Southeast Airport Group unit buys operator for $992M

CPC Aeroportos’ 20-airport portfolio is now part of ASUR, while first-half adjusted EBITDA declined 7.5%.

Rhea-AI Filing Summary

SOUTHEAST AIRPORT GROUP (symbol: ASR) is the issuer of record for a Form 6-K filing submitted to the SEC. ASUR’s subsidiary Aeropuerto de Cancún completed its acquisition of 100% of CPC Aeroportos on September 1, 2026, from Motiva for approximately R$5.1 billion (U.S.$992.2 million), following customary closing adjustments. CPC Aeroportos operates a portfolio of 20 airports in Latin America. At closing, Aeropuerto de Cancún drew U.S.$1,230 million under a bridge facility to fund the purchase price and related costs; unused commitments were terminated effective September 9, 2026.

For the six months ended June 30, 2026, ASUR reported revenue of Ps.18,377.9 million, up 5.0%, while Adjusted Consolidated EBITDA fell 7.5% to Ps.9,942.5 million and net income fell 10.1% to Ps.5,311.0 million. Passenger traffic was approximately 36.2 million, compared with 36.3 million a year earlier. These historical results include ASUR Airports, acquired in December 2025, but exclude CPC Aeroportos, whose acquisition closed after the period.

At June 30, cash and cash equivalents were Ps.11,641.4 million, Total Debt was Ps.26,779.7 million and Total Net Debt was Ps.15,138.3 million. Operating cash flow was Ps.7,646.4 million, up 31.6% year over year.

Positive

• Total revenue rose 5.0% to Ps.18,377.9 million in first-half 2026.
• Operating cash flow increased 31.6% to Ps.7,646.4 million.

Negative

• Adjusted Consolidated EBITDA fell 7.5%; net income fell 10.1%.

Filing Explained

The bridge facility matures November 5, 2027; about 189 million dollars of its draw is intended for minority purchases or, if unused, debt repayment.

On August 20, 2026, ASUR shareholders approved a reorganization under which minority shareholder ITA will merge into ASUR to integrate technical-assistance and technology-transfer services. The company expects the transaction to issue approximately 7.2 million new shares; if issued, these would increase the share count and reduce existing holders’ percentage ownership, absent offsetting changes.

Separately, Aeropuerto de Cancún agreed to acquire Zurich Airport International’s 25% interest in the Confins holding company, equivalent to an indirect 12.75% interest in the airport concession; closing is expected in December 2026, subject to conditions and adjustments. Infraero has exercised a tag-along right over its 49% concession interest, with the acquisition still subject to definitive documentation; a contemplated 10.2% Curaçao-related interest purchase remains subject to negotiation, documentation and closing conditions.

The CPC Bridge Facility carries interest at Term SOFR plus a variable margin ranging from 125 basis points annually during the first 90 days to 250 basis points from day 451 through its November 5, 2027 maturity. Of the U.S.$1,230 million drawn, approximately U.S.$189 million is intended for the potential minority-interest purchases; any amount not used for them is to repay outstanding debt.

5 terms

Adjusted Consolidated EBITDA financial

"Adjusted Consolidated EBITDA decreased 7.5% to Ps.9,942.5 million"

Adjusted consolidated EBITDA is a company’s total operating profit across all subsidiaries before interest, taxes, depreciation and amortization, further cleaned up by removing one-time items and unusual costs so recurring cash performance is clearer. Investors use it like a simplified cash-earnings number to compare profitability and ability to pay debt or fund growth across periods and peers—similar to looking at a household’s regular monthly income after stripping out rare or accidental expenses.

Debt Coverage Ratio financial

"ASUR’s Debt Coverage Ratio was 7.9x"

Term SOFR financial

"applicable Term SOFR rate plus a variable margin"

Term SOFR is a benchmark interest rate that reflects the cost of borrowing money over a specific period, based on actual transactions in the financial markets. It is used by lenders and borrowers to set the interest rates on loans and financial contracts, helping to ensure rates are fair and transparent. For investors, understanding term SOFR helps gauge borrowing costs and the overall direction of interest rates in the economy.

acquisition method of accounting financial

"using the acquisition method of accounting in accordance with IFRS 3"

Total Net Debt financial

"Total Net Debt was Ps.15,138.3 million"

Non-IFRS Financial Measures

For convenience of investors, this report presents certain non-IFRS financial measures with respect to ASUR’s historical consolidated financial information presented herein, which does not include or give effect to CPC Aeroportos or the Acquisition. These measures are not recognized under IFRS Accounting Standards. Specifically, we present:

· EBITDA, Adjusted Consolidated EBITDA, Adjusted EBITDA Margin and Total Revenue Excluding Construction Services Revenue;

· Total Debt and Total Net Debt;

· Total Debt / LTM Adjusted Consolidated EBITDA and Total Net Debt / LTM Adjusted Consolidated EBITDA; and

· Debt Coverage Ratio.

This report also presents CPC Aeroportos Adjusted EBITDA, as defined and reconciled below.

This report also presents certain financial information for the twelve months ended June 30, 2026 (“LTM”). We calculate such LTM figures by adding the applicable figure for the six-month period ended June 30, 2026 to the corresponding figure for the year ended December 31, 2025 and subtracting the corresponding figure for the six-month period ended June 30, 2025.

Non-IFRS financial measures do not have standardized meanings and may not be directly comparable to similarly titled measures adopted by other companies. We present these non-IFRS financial measures as supplemental measures of our operating performance, indebtedness, liquidity and leverage.

These measures have limitations as analytical tools and should not be considered in isolation or as substitutes for analysis of our results of operations or financial condition presented in accordance with IFRS Accounting Standards.

The definitions and calculations set forth immediately below relate solely to ASUR’s historical consolidated financial information and do not apply to CPC Aeroportos or its historical financial information. CPC Aeroportos Adjusted EBITDA is separately defined and reconciled below.

EBITDA, Adjusted Consolidated EBITDA and Adjusted EBITDA Margin

ASUR calculates EBITDA as consolidated net income plus income tax, share of loss of investments accounted for using the equity method, comprehensive financing costs and depreciation and amortization. Adjusted Consolidated EBITDA is calculated as EBITDA adjusted for certain items, consisting of excluding the effect of IFRS 16 in respect of ASUR Airports, LLC and adding back non-ordinary items in Mexico. According to ASUR, non-ordinary items in Mexico generally consist of expenses incurred in connection with accidents or weather events. We believe Adjusted Consolidated EBITDA provides useful information to investors in evaluating our operating performance and our ability to service debt and fund capital expenditures. EBITDA and Adjusted Consolidated EBITDA should not be considered an alternative to net income as an indicator of our operating performance or an alternative to cash flow as an indicator of liquidity.

Total Revenue Excluding Construction Services Revenue is calculated as total revenue less construction services revenue and is presented to exclude the effect of IFRIC 12 with respect to the construction of, or improvements to, concessioned assets. Adjusted EBITDA Margin is calculated by dividing Adjusted Consolidated EBITDA by Total Revenue Excluding Construction Services Revenue. In Mexico and Puerto Rico, because equal amounts of construction services revenue and construction costs are recognized, construction services revenue does not affect Adjusted Consolidated EBITDA but does affect the denominator used to calculate Adjusted EBITDA Margin. In Colombia, construction services revenue includes a reasonable margin over actual construction costs and therefore does affect Adjusted Consolidated EBITDA. We believe Adjusted EBITDA Margin provides useful information to investors in evaluating our operating performance.

The following table sets forth a reconciliation of EBITDA and Adjusted Consolidated EBITDA to net income, and the calculation of Adjusted EBITDA Margin, for the six-month periods ended June 30, 2026 and 2025 and the year ended December 31, 2025.

Total Debt, Total Net Debt and Leverage Ratios

Total Debt represents the sum of short-term bank loans, short-term debt, long-term bank loans and long-term debt. Total Net Debt is calculated as Total Debt less cash and cash equivalents. Only cash and cash equivalents are deducted in calculating Total Net Debt.

Total Debt / LTM Adjusted Consolidated EBITDA is calculated as Total Debt divided by LTM Adjusted Consolidated EBITDA for the applicable twelve-month period, and Total Net Debt / LTM Adjusted Consolidated EBITDA is calculated as Total Net Debt divided by LTM Adjusted Consolidated EBITDA for the applicable twelve-month period. For purposes of these leverage ratios, “LTM Adjusted Consolidated EBITDA” means ASUR’s Adjusted Consolidated EBITDA for the applicable twelve-month period, with the twelve-month amount for an interim reporting date determined by adding the applicable six-month period to the preceding full year and subtracting the corresponding six-month period of the preceding year. We believe these measures provide useful information to investors in evaluating our indebtedness, liquidity and leverage. Total Debt and Total Net Debt should not be considered alternatives to total liabilities or other measures calculated in accordance with IFRS Accounting Standards, and the leverage ratios should not be considered in isolation or as substitutes for analysis of our financial position and results of operations.

ASUR reports a Debt Coverage Ratio using the calculation methodologies applicable to its Mexico and Puerto Rico operations, which reflect the formulas contained in the applicable financing arrangements in each jurisdiction. For Mexico, the applicable interest coverage ratio is calculated as LTM EBITDA divided by LTM interest expense, subject to the adjustments provided in the applicable financing arrangements. For Puerto Rico, the applicable debt coverage ratio is calculated as LTM Cash Flow Generation divided by LTM debt service, in each case as defined in the applicable financing arrangements. Colombia was included in this calculation for periods in which Airplan had outstanding debt; Airplan prepaid its remaining syndicated bank loan on April 22, 2026 and, accordingly, Colombia is not included in the calculation as of June 30, 2026. The aggregate Debt Coverage Ratio combines the applicable numerator and denominator amounts for Mexico and Puerto Rico, and, for periods prior to June 30, 2026, Colombia. As of June 30, 2026, ASUR’s Debt Coverage Ratio was 7.9x.

CPC Aeroportos Adjusted EBITDA

For purposes of this report, “CPC Aeroportos Adjusted EBITDA” means CPC Aeroportos’ profit for the period or year, adjusted to reverse the effects of current and deferred income tax and social security contribution expense or benefit and net finance costs, depreciation and amortization, and adjusted to reverse the results of equity-accounted investees.

CPC Aeroportos Adjusted EBITDA is a non-IFRS measure presented as a supplemental measure of operating performance; it is not a substitute for profit or cash flow and may not be comparable to similarly titled measures used by other companies. CPC Aeroportos management uses CPC Aeroportos Adjusted EBITDA as a supplemental measure to evaluate the operating performance of its fully consolidated operations and to facilitate comparisons of operating performance across periods. We believe CPC Aeroportos Adjusted EBITDA provides additional useful information to investors because it presents operating performance independently of income tax and social security contribution effects, net financing results and depreciation and amortization, and excludes the results of equity-accounted investees, which are not fully consolidated in CPC Aeroportos’ financial statements.

The adjustment for net finance costs reverses CPC Aeroportos’ net financing result, including both financial expenses and financial revenues. The adjustment for the results of equity-accounted investees removes CPC Aeroportos’ share of the net results of its joint ventures and other investments accounted for under the equity method because the underlying revenues, operating expenses, depreciation and amortization, financing costs and income taxes of those investees are not consolidated in CPC Aeroportos’ financial statements. Accordingly, CPC Aeroportos Adjusted EBITDA does not reflect the operating performance of CPC Aeroportos’ equity-accounted joint ventures.

CPC Aeroportos Adjusted EBITDA is calculated separately from the EBITDA and Adjusted Consolidated EBITDA measures presented with respect to ASUR. Although these measures are based on a similar EBITDA framework, the adjustments applied to each measure differ and, accordingly, CPC Aeroportos Adjusted EBITDA is not directly comparable to ASUR’s EBITDA or Adjusted Consolidated EBITDA.

In making an investment decision, investors should not consider CPC Aeroportos Adjusted EBITDA as an alternative or substitute for measures presented in accordance with IFRS Accounting Standards, including profit or operating cash flows, or consider it in isolation from CPC Aeroportos’ financial results presented in accordance with IFRS Accounting Standards.

Certain numerical figures shown as totals in some tables may not be an arithmetic aggregation of the figures that precede them due to rounding.

OPERATING AND FINANCIAL REVIEW

The following is a summary and discussion of our unaudited condensed consolidated interim financial information as of June 30, 2026 and December 31, 2025 and for the six-month periods ended June 30, 2026 and 2025. The following tables and discussion should be read in conjunction with our audited consolidated financial statements included in our annual report on Form 20-F for the year ended December 31, 2025.

Our unaudited condensed consolidated interim financial information has been prepared in accordance with IAS 34 “Interim Financial Reporting.” The same accounting policies, presentation and methods of computation applied in our audited consolidated financial statements included in our annual report on Form 20-F for the year ended December 31, 2025 have been applied in our unaudited condensed consolidated interim financial information, except for income tax and the adoption of amended IFRS Accounting Standards effective from January 1, 2026. Our unaudited condensed consolidated interim financial information does not include all of the information and disclosures required in annual financial statements and should be read in conjunction with our audited consolidated financial statements. Results for the six-month period ended June 30, 2026 are not necessarily indicative of results for the year ending December 31, 2026 or any future period.

Because the acquisition of ASUR Airports was completed on December 11, 2025, our consolidated results for the six-month period ended June 30, 2026 include the results of ASUR Airports, while our consolidated results for the six-month period ended June 30, 2025 do not include the results of that business.

Beginning in 2026, ASUR Airports is presented as a separate reportable segment because its results are regularly reviewed separately by our chief operating decision maker and are material to an understanding of our commercial operations in the United States.

The historical financial information and related operating and financial review presented below do not include CPC Aeroportos and do not give effect to the Acquisition, which was completed after June 30, 2026. See “Recent Developments—Acquisition of CPC Aeroportos and Related Financing” and “Pro Forma Financial Information.”

(2) Total Revenue Excluding Construction Services Revenue is calculated as total revenue less construction services revenue and is presented to exclude the effect of IFRIC 12 with respect to the construction of, or improvements to, concessioned assets. In Mexico and Puerto Rico, because equal amounts of construction services revenue and construction costs are recognized, construction services revenue does not affect Adjusted Consolidated EBITDA but does affect the denominator used to calculate Adjusted EBITDA Margin. In Colombia, construction services revenue includes a reasonable margin over actual construction costs and therefore does affect Adjusted Consolidated EBITDA. We use Total Revenue Excluding Construction Services Revenue as the denominator for Adjusted EBITDA Margin because we believe it provides a more meaningful measure of our operating performance.

Consolidated Results of Operations for the Six-Month Periods Ended June 30, 2026 and 2025

The comparability of our financial and operating performance for the six-month period ended June 30, 2026 as compared to the corresponding period in 2025 was affected by the inclusion of the results of ASUR Airports, which we acquired on December 11, 2025, and by translation effects resulting from fluctuations in the exchange rates of the currencies of our foreign operations relative to the Mexican peso. Accordingly, our consolidated results for the six-month period ended June 30, 2026 include the results of ASUR Airports for the full six-month period, while our consolidated results for the six-month period ended June 30, 2025 do not include the results of that business.

The historical financial information and related operating and financial review presented below do not include CPC Aeroportos and do not give effect to the Acquisition, which was completed on September 1, 2026. See “Recent Developments—Acquisition of CPC Aeroportos and Related Financing” and “—Pro Forma Financial Information.”

Revenues

Our consolidated total revenues increased 5.0%, or Ps.875.0 million, to Ps.18,377.9 million for the six-month period ended June 30, 2026 from Ps.17,502.9 million for the corresponding period in 2025. The increase primarily reflected a 41.2% increase in construction services revenues and an 8.0% increase in non-aeronautical services revenues, partially offset by a 3.5% decrease in aeronautical services revenues. Excluding construction services revenues, total revenues increased 0.6% to Ps.15,698.8 million from Ps.15,604.9 million.

Revenues from aeronautical services. Aeronautical services revenues decreased 3.5%, or Ps.351.8 million, to Ps.9,667.6 million for the six-month period ended June 30, 2026 from Ps.10,019.5 million for the corresponding period in 2025. Total passenger traffic decreased 0.3% to approximately 36.2 million passengers from approximately 36.3 million passengers. Passenger traffic at our Mexican airports decreased 2.4% and passenger traffic at LMM Airport decreased 2.8%, partially offset by a 7.3% increase in passenger traffic at our Colombian airports. The decrease in aeronautical services revenues principally reflected lower passenger charges, landing fees and passenger walkway revenues.

 8

Revenues from non-aeronautical services. Non-aeronautical services revenues increased 8.0%, or Ps.445.7 million, to Ps.6,031.1 million for the six-month period ended June 30, 2026 from Ps.5,585.4 million for the corresponding period in 2025. The increase primarily reflected Ps.822.4 million of revenues contributed by ASUR Airports, which had no comparable contribution in the prior-year period, and a 9.2% increase in non-aeronautical services revenues in Colombia. These increases were partially offset by decreases of 9.3% and 5.4% in non-aeronautical services revenues in Mexico and Puerto Rico, respectively. Total commercial revenues per passenger increased 8.5% to Ps.153.5 from Ps.141.5. The principal drivers of these changes were increases in food and beverage and other services revenues, partially offset by decreases in duty-free store and car rental revenues.

Revenues from construction services. Construction services revenues increased 41.2%, or Ps.781.1 million, to Ps.2,679.2 million for the six-month period ended June 30, 2026 from Ps.1,898.0 million for the corresponding period in 2025, principally reflecting higher construction activity in Mexico and Colombia. Construction services revenues in Mexico increased 43.4% to Ps.2,382.4 million, while construction services revenues in Colombia increased to Ps.64.3 million from Ps.6.9 million. Construction services revenues in Puerto Rico increased 1.3% to Ps.232.5 million.

Operating Expenses

Our consolidated operating expenses increased 22.7%, or Ps.1,810.9 million, to Ps.9,800.0 million for the six-month period ended June 30, 2026 from Ps.7,989.1 million for the corresponding period in 2025. Excluding construction costs, operating expenses increased 16.9% to Ps.7,120.8 million from Ps.6,091.0 million.

The increase in operating expenses reflected, among other factors, a 41.2% increase in construction services costs to Ps.2,679.2 million, a 29.6% increase in depreciation and amortization to Ps.1,601.0 million, an 11.2% increase in short-term employee benefits to Ps.1,167.7 million and a 45.2% increase in professional fees to Ps.280.4 million, as well as increases in security services, expected credit loss expense and other costs. These increases were partially offset by a 7.3% decrease in concession fees and Airport Use Right (DUAC) to Ps.1,378.1 million, a 6.9% decrease in technical assistance fees to Ps.198.6 million and a 4.4% decrease in electricity costs to Ps.271.6 million. The six-month period ended June 30, 2026 included approximately Ps.469.0 million of net rental costs associated with ASUR Airports. At the consolidated level, the allowance for doubtful accounts associated with ASUR Airports was approximately Ps.40.7 million.

Operating Profit

As a result of the factors described above, operating profit decreased 9.8%, or Ps.935.9 million, to Ps.8,578.0 million for the six-month period ended June 30, 2026 from Ps.9,513.8 million for the corresponding period in 2025. Operating margin decreased to 46.7% from 54.4%.

Adjusted Consolidated EBITDA decreased 7.5% to Ps.9,942.5 million for the six-month period ended June 30, 2026 from Ps.10,749.8 million for the corresponding period in 2025, and Adjusted EBITDA Margin decreased to 63.3% from 68.9%.

Comprehensive Financing Cost

Our comprehensive financing cost decreased 1.9% to Ps.1,076.9 million for the six-month period ended June 30, 2026 from Ps.1,098.1 million for the corresponding period in 2025. Interest expense increased to Ps.1,532.3 million from Ps.574.1 million, interest income decreased to Ps.588.0 million from Ps.847.7 million, and our net foreign exchange loss decreased to Ps.220.4 million from Ps.1,371.6 million. The 2026 period also included a Ps.87.9 million fair value gain, compared with no corresponding amount in 2025. Interest expense included Ps.238.8 million related to lease liabilities, principally associated with ASUR Airports.

Taxes

Income tax expense, including current and deferred income taxes, decreased 12.7% to Ps.2,188.9 million for the six-month period ended June 30, 2026 from Ps.2,506.0 million for the corresponding period in 2025. Our effective income tax rate was 29.2% for the six-month period ended June 30, 2026 compared with 29.8% for the corresponding period in 2025. The decrease in income tax expense principally reflected lower income before income taxes and the lower effective income tax rate.

Net Income

As a result of the factors described above, net income decreased 10.1%, or Ps.597.4 million, to Ps.5,311.0 million for the six-month period ended June 30, 2026 from Ps.5,908.4 million for the corresponding period in 2025. Net income attributable to controlling interest decreased 9.7% to Ps.5,109.6 million from Ps.5,660.6 million, while net income attributable to non-controlling interest decreased 18.7% to Ps.201.4 million from Ps.247.8 million.

Liquidity and Capital Resources

Sources of Liquidity

Historically, our operations, financing and investing activities have been funded primarily through cash flows from operations. We have also used external financing, including bank borrowings and debt issued by Aerostar, to fund capital expenditures and acquisitions.

As of June 30, 2026, cash and cash equivalents were Ps.11,641.4 million, compared with Ps.11,116.3 million as of December 31, 2025. Total indebtedness was Ps.26,779.7 million as of June 30, 2026, compared with Ps.27,486.6 million as of December 31, 2025. Short-term bank loans and short-term debt totaled Ps.16,271.7 million as of June 30, 2026, compared with Ps.625.9 million as of December 31, 2025, while long-term bank loans and long-term debt totaled Ps.10,507.9 million as of June 30, 2026, compared with Ps.26,860.7 million as of December 31, 2025. The decrease in total indebtedness primarily reflected foreign-currency translation effects and the repayment of Ps.323.9 million of principal in Colombia.

As of June 30, 2026, 68.3% of our indebtedness was denominated in Mexican pesos and 31.7% was denominated in U.S. dollars, consisting of indebtedness of Aerostar in Puerto Rico. As of the same date, Aerostar had undrawn revolving credit facilities of U.S.$20.0 million and U.S.$10.0 million.

As of June 30, 2026, Total Net Debt was Ps.15,138.3 million and Total Net Debt / LTM Adjusted Consolidated EBITDA was 0.8x.

Based on our current forecasts, we expect to meet our financial obligations as they fall due for at least the next twelve months.

Cash Flows for the Six-Month Period Ended June 30, 2026 as Compared to Cash Flows for the Six-Month Period Ended June 30, 2025

The following table summarizes the sources and uses of cash for the six-month periods ended June 30, 2026 and 2025, from our consolidated statements of cash flows:

		Six-month period ended June 30,
		2026								2025
		U.S.$ (1)				Ps.				U.S.$ (1)				Ps.
		(in millions) (unaudited)

(1) U.S. dollar amounts presented in this table have been translated at Ps.17.4693 per U.S.$1.00 solely for convenience.

Operating activities. Net cash flows provided by operating activities increased 31.6%, or Ps.1,838.0 million, to Ps.7,646.4 million for the six-month period ended June 30, 2026 from Ps.5,808.4 million for the corresponding period in 2025. The increase principally reflected lower income taxes paid and higher adjustments to income before income taxes, including depreciation and amortization and interest expense, partially offset by lower income before income taxes and less favorable net movements in operating assets and liabilities.

Investing activities. Net cash flows used in investing activities were Ps.1,830.1 million for the six-month period ended June 30, 2026, compared with net cash flows provided by investing activities of Ps.309.6 million for the corresponding period in 2025. The change principally reflected the absence in 2026 of the Ps.1,537.7 million redemption of investments in financial instruments recorded in the 2025 period, higher investments in machinery, furniture, equipment and concession improvements of Ps.2,494.6 million compared with Ps.2,035.8 million, and lower interest received of Ps.588.0 million compared with Ps.846.9 million, partially offset by movements in restricted cash.

Financing activities. Net cash flows used in financing activities decreased 13.4%, or Ps.805.6 million, to Ps.5,216.4 million for the six-month period ended June 30, 2026 from Ps.6,022.0 million for the corresponding period in 2025. The decrease in net cash used principally reflected dividends paid of Ps.3,000.0 million in the 2026 period compared with Ps.15,000.0 million in the 2025 period, partially offset by the absence of Ps.9,500.0 million of bank borrowings obtained in the 2025 period, Ps.323.9 million of bank-loan principal repayments in 2026, higher lease principal payments of Ps.456.2 million compared with Ps.5.7 million and higher interest payments of Ps.1,334.7 million compared with Ps.509.0 million.

Indebtedness

As of June 30, 2026, our consolidated outstanding indebtedness was Ps.26,779.7 million, a decrease of 2.6% from Ps.27,486.6 million as of December 31, 2025. Our indebtedness as of June 30, 2026 was concentrated in Mexico and Puerto Rico.

The following table summarizes selected consolidated debt information as of June 30, 2026 and December 31, 2025:

		As of June 30,  2026								As of December 31,  2025
		U.S.$ (1)				Ps.				U.S.$ (1)				Ps.
		(in millions)
Short-term bank loans			908.3				15,867.0				12.6				220.4
Short-term debt			23.2				404.7				23.2				405.5
Long-term bank loans			138.7				2,423.4				1,053.1				18,396.3
Long-term debt			462.8				8,084.5				484.5				8,464.4
Total Debt			1,533.0				26,779.7				1,573.4				27,486.6
Cash and cash equivalents			666.4				11,641.4				636.3				11,116.3

(1) U.S. dollar amounts presented in this table have been translated at Ps.17.4693 per U.S.$1.00 solely for convenience.

At June 30, 2026, Mexico had Ps.18,290.5 million of indebtedness, consisting of Ps.15,867.0 million of short-term bank loans and Ps.2,423.4 million of long-term bank loans. Puerto Rico had Ps.8,489.2 million of indebtedness, consisting of Ps.404.7 million of short-term debt and Ps.8,084.5 million of long-term debt. Colombia and our United States commercial operations had no indebtedness reflected in ASUR’s June 30, 2026 Total Debt calculation. The increase in Mexico's indebtedness from December 31, 2025 to June 30, 2026 primarily reflected accrued interest and did not result from additional borrowings.

 13

As of June 30, 2026, we were in compliance with the financial covenants under our borrowing arrangements. The net leverage ratio for the relevant Mexican facilities was approximately 1.7 times, compared with a maximum permitted ratio of 3.5 times, and the applicable interest coverage ratios ranged from approximately 7.9 to 11.1 times. Aerostar’s debt service coverage ratio was approximately 1.9 times compared with its applicable minimum requirement.

The CPC Bridge Facility, which had original aggregate commitments of U.S.$1,299 million and under which U.S.$1,230 million was drawn at the closing of the Acquisition, was entered into after June 30, 2026 and therefore is not reflected in the historical indebtedness described above. Effective September 9, 2026, all remaining unused commitments under the CPC Bridge Facility were terminated. See “Recent Developments—Acquisition of CPC Aeroportos and Related Financing” and “Pro Forma Financial Information.”

As of June 30, 2026, CPC Aeroportos had Ps.20,918.7 million of consolidated indebtedness, consisting of Ps.178.0 million of current loans and financing, Ps.4,565.2 million of non-current loans and financing, Ps.255.3 million of current debentures and Ps.15,920.1 million of non-current debentures, including indebtedness incurred by subsidiaries in Brazil, Costa Rica and Curaçao. Because CPC Aeroportos was acquired after June 30, 2026, this indebtedness is not included in ASUR’s historical indebtedness described above. Of this indebtedness, approximately Ps.17,469.3 million (U.S.$1.0 billion) related to debt facilities of BH Airport, Bloco Sul and Bloco Central in respect of which Motiva acts as guarantor. In connection with the Acquisition, Aeropuerto de Cancún agreed to use its best efforts to obtain the replacement, release or extinguishment of the applicable Motiva guarantees following the closing of the Acquisition. The replacement credit support, which remains under negotiation, may include corporate guarantees and/or additional collateral. Further, Corporación Quiport S.A., an equity-accounted joint venture of CPC Aeroportos in Ecuador, had Ps.8,377.1 million of financial liabilities as of June 30, 2026 on a 100% basis; such indebtedness is not consolidated by CPC Aeroportos. Following the Acquisition, approximately U.S.$49 million of indebtedness of Concessionária do Aeroporto da Pampulha S.A. and CPC Aeroportos was repaid in September 2026. Because such repayment occurred after June 30, 2026, the related amounts remain reflected in the June 30, 2026 historical information. See Exhibits 99.3 and 99.4.

Capital expenditures increased 22.5% to Ps.2,494.6 million for the six-month period ended June 30, 2026 from Ps.2,035.8 million for the corresponding period in 2025. Capital expenditures in the 2026 period consisted principally of Ps.2,173.1 million invested in the modernization of our Mexican airports under our master development plans, Ps.253.0 million in Puerto Rico, Ps.64.4 million in Colombia and Ps.4.1 million in our United States commercial operations.

In addition, CPC Aeroportos’ Brazilian airport concessions include significant capital investment commitments over their respective concession terms. The aggregate investment commitments relating to the sixth-round concessions are approximately R$14.5 billion (U.S.$2.8 billion) and those relating to the seventh-round concessions are approximately R$8.6 billion (U.S.$1.7 billion).

RECENT DEVELOPMENTS

Acquisition of CPC Aeroportos and Related Financing

On September 1, 2026, our subsidiary Aeropuerto de Cancún completed the Acquisition by acquiring the entire equity interest owned by Motiva Infraestrutura de Mobilidade S.A. (“Motiva”) in CPC Aeroportos. The purchase price for Motiva’s interest was approximately R$5.1 billion (U.S.$992.2 million), following customary closing adjustments. CPC Aeroportos operates and manages, through its investments in concessionaire companies, a portfolio of 20 airports in Latin America, including 17 in Brazil and one in each of Ecuador, Costa Rica and Curaçao. During 2025 and the six-month periods ended June 30, 2025 and 2026, the airports operated and managed by CPC Aeroportos served approximately 48 million, 23 million and 24 million passengers, respectively.

At the September 1, 2026 closing, Aeropuerto de Cancún acquired 100% of the shares of CPC Aeroportos and thereby acquired CPC Aeroportos’ then-existing direct and indirect equity interests in the underlying airport businesses. Certain of those interests are held through intermediate holding companies and certain underlying airport concessionaires continue to have minority shareholders.

In addition to the Acquisition, Aeropuerto de Cancún is pursuing the acquisition of certain additional minority equity interests in underlying airport holding and concessionaire companies. These separate acquisitions were not completed concurrently with the September 1, 2026 Acquisition. Aeropuerto de Cancún has agreed to acquire Zurich Airport International AG’s 25% interest in Sociedade de Participação no Aeroporto de Confins S.A., which is equivalent to an indirect 12.75% interest in Concessionária do Aeroporto Internacional de Confins S.A. This acquisition is expected to close in December 2026, subject to the satisfaction of applicable closing conditions and certain adjustments under the relevant transaction documents. In addition, Infraero has exercised its tag-along right with respect to its 49% interest in Concessionária do Aeroporto Internacional de Confins S.A., and the related acquisition remains subject to the execution of definitive transaction documentation. Separately, Aeropuerto de Cancún is contemplating the acquisition of a 10.2% Curaçao-related minority interest held by Zurich Airport International AG, subject to the negotiation and execution of applicable transaction documentation, the satisfaction of applicable closing conditions and certain adjustments.

On August 14, 2026, Aeropuerto de Cancún, as borrower, and ASUR, as guarantor, entered into a senior unsecured bridge credit facility with original aggregate commitments of U.S.$1,299 million (the “CPC Bridge Facility”). At the closing of the Acquisition, Aeropuerto de Cancún drew U.S.$1,230 million under the CPC Bridge Facility to fund the purchase price and related costs. Approximately U.S.$189 million of the amount drawn is intended to fund the potential acquisitions of the interests held by Zurich Airport International AG and Infraero described above. To the extent such amounts are not used to fund the minority interest acquisitions described above, they will be applied to repay outstanding indebtedness. Effective September 9, 2026, Aeropuerto de Cancún terminated all remaining unused commitments under the CPC Bridge Facility. The CPC Bridge Facility bears interest at the applicable Term SOFR rate plus a variable margin ranging from 125 basis points per annum during the first 90 days to 250 basis points per annum from day 451 through maturity, and matures on November 5, 2027.

Acquisition of URW Airports

On December 11, 2025, our subsidiary ASUR US Commercial Airports, LLC completed the acquisition of URW Airports, LLC, now ASUR Airports, LLC. The transaction was announced at an enterprise value of U.S.$295 million, and, as of December 11, 2025, the purchase price was adjusted to U.S.$308 million. Through ASUR Airports, LLC, we operate and manage retail, food and beverage and other commercial concession programs at several U.S. airports, including Terminals 1, 2, 3 and 6, the Tom Bradley International Terminal and the Tom Bradley International Terminal West at Los Angeles International Airport, Terminal 5 at Chicago O’Hare International Airport, and Terminal 8 and New Terminal One at John F. Kennedy International Airport.

On December 5, 2025, Aeropuerto de Cancún and ASUR US Commercial Airports, LLC, as borrowers, and ASUR, as guarantor, entered into a Ps.6,390 million senior unsecured bridge credit facility (the “ASUR US Bridge Facility”) to finance a portion of the purchase price of ASUR Airports, LLC and related transaction costs, fees and expenses. The ASUR US Bridge Facility bears interest at the applicable TIIE de Fondeo rate plus a variable margin ranging from 75 basis points per annum during the first 90 days to 200 basis points per annum from day 451 through maturity, and matures on June 5, 2027. ASUR US Commercial Airports, LLC funded the purchase price with cash on hand and borrowings under the ASUR US Bridge Facility.

ASUR Airports Commercial Program Terms

The current terms of our commercial programs at Los Angeles International Airport extend through June 30, 2038, and the term of our program at ORD Terminal 5 extends through June 8, 2039. The term of our program at JFK New Terminal One extends until ten years after the earlier of (i) the completion date of the final phase constructed by the terminal operator under the applicable lease agreement and (ii) the date set forth in the baseline schedule for completion of Phase B2, an expansion of the terminal that will include additional commercial spaces, but in no event later than October 31, 2039, in each case subject to applicable extension rights. The current term of our program at JFK Terminal 8 extends through December 31, 2036.

Corporate Reorganization Involving ITA

On August 20, 2026, our shareholders approved a corporate reorganization pursuant to which Inversiones y Técnicas Aeroportuarias, S.A.P.I. de C.V. (“ITA”), which was one of our minority shareholders, will merge into ASUR, in order to integrate into ASUR the technical assistance and technology transfer services previously provided by ITA. The transaction involves entities under common control and is expected to result in the issuance of approximately 7.2 million new shares of ASUR’s capital stock. We do not expect the transaction to have a significant impact on our consolidated financial statements.

PRO FORMA FINANCIAL INFORMATION

The unaudited pro forma condensed combined financial information furnished as Exhibit 99.4 to this report has been prepared in accordance with Article 11 of Regulation S-X and consists of (i) an unaudited pro forma condensed combined statement of financial position as of June 30, 2026, giving effect to the Acquisition and the related financing as if they had occurred on June 30, 2026, and (ii) unaudited pro forma condensed combined statements of income for the year ended December 31, 2025 and for the six-month period ended June 30, 2026, giving effect to the Acquisition and the related financing as if they had occurred on January 1, 2025.

The Acquisition is being accounted for in our consolidated financial statements as a business combination using the acquisition method of accounting in accordance with IFRS 3 “Business Combinations,” with ASUR treated as the accounting acquirer. The pro forma purchase accounting adjustments, including the allocation of the purchase price to the assets acquired and liabilities assumed, are based on preliminary estimates and assumptions and are subject to change as the purchase price allocation is finalized. The financing adjustments reflect the U.S.$1,230 million actually drawn under the CPC Bridge Facility at the closing of the Acquisition, presented net of directly attributable issuance costs. Actual amounts may differ materially from the preliminary amounts reflected in the pro forma financial information.

Notes to the Unaudited Condensed Consolidated Interim Financial Statements

June 30, 2026 and December 31, 2025

Figures expressed in thousands of Mexican pesos (Ps$), thousands of U.S. dollars (USD$) and thousands of Colombian pesos (COP$), except for number of shares, earnings per share and exchange rates.

Note 1 - General information and significant events:

Grupo Aeroportuario del Sureste, S. A. B. de C. V. (the Company or ASUR) and its subsidiaries (collectively, the Group) operate nine airports in southeastern Mexico, the Luis Muñoz Marín International Airport in San Juan, Puerto Rico, six airports in Colombia and commercial programs at selected airport terminals in the United States. The Company’s Series B shares are listed on the Mexican Stock Exchange and its American Depositary Shares are listed on the New York Stock Exchange.

1.1 Sustainability and climate-related matters

The Group’s Sustainability Committee oversees the sustainability strategy, proposed targets, mitigation and adaptation initiatives and the sustainability report. The Group’s principal physical climate risks include extreme heat, which can increase electricity consumption for cooling systems, and hurricanes, particularly for Cancún and San Juan. Principal transition risks include higher airline operating costs that could affect passenger demand, higher electricity costs and requirements to incorporate renewable energy.

Management evaluated the measures and actions implemented in response to sustainability and climate-related risks and concluded that their financial effects were reflected in the estimates and judgments applied in these condensed consolidated interim financial statements. No additional material financial impact was identified at June 30, 2026.

1.2 Seasonality and passenger traffic

Passenger traffic and the Group’s results are affected by seasonal travel patterns. Results for an interim period are therefore not necessarily indicative of the results for the full year. Passenger traffic for the six-month periods ended June 30 was as follows:

Passengers (thousands)		Six months period ended June 30, 2026				Six months period ended June 30, 2025				Three months period ended June 30, 2026				Three months period ended June 30, 2025
Domestic – Mexico			9,396				9,516				4,850				4,935
Domestic – Aerostar			6,151				6,351				3,009				3,123
Domestic – Airplan			6,754				6,252				3,302				3,173
Total domestic passengers			22,301				22,119				11,161				11,231
International – Mexico			11,054				11,446				4,661				5,081
International – Aerostar			834				838				445				456
International – Airplan			2,025				1,934				983				966
Total international passengers			13,913				14,218				6,089				6,503
Total passengers			36,214				36,337				17,250				17,734

Note 2 - Basis of preparation and material accounting policy information:

These condensed consolidated interim financial statements as of June 30, 2026, December 31, 2025 and for the three and six-month periods ended June 30, 2026 and 2025 have been prepared in accordance with International Accounting Standard (IAS) 34, Interim Financial Reporting. These condensed consolidated interim financial statements prepared in accordance with International Financial Reporting Standards as issued by the IASB (”IFRS Accounting Standards”) do not include all the information and disclosures required in the annual financial statements and should be read in conjunction with the Group’s annual consolidated financial statements as of December 31, 2025, and any public announcements made by the Company during the interim reporting period. However, selected explanatory notes are included to explain events and transactions that are significant to an understanding of changes in the Group’s financial position and performance since the last annual consolidated financial statements.

The same accounting policies, presentation and methods of computation applied in the annual consolidated financial statements for 2025 have been applied in these condensed consolidated interim financial statements, except for the Income tax (see note 15) and the adoption of amended IFRS Accounting Standards effective from January 1, 2026. These financial statements have been prepared on a going concern basis and principally under the historical cost convention, except for investment properties and other items measured at fair value in accordance with the applicable IFRS Accounting Standards.

2.1 Use of estimates and judgments

The preparation of condensed consolidated interim financial statements requires management to make judgments, estimates and assumptions that affect the application of accounting policies and the reported amounts of assets, liabilities, income and expenses. Actual results may differ from these estimates. Estimates and underlying assumptions are reviewed on an ongoing basis, and revisions are recognized in the period in which the estimates are revised and in any future periods affected. Material changes in judgments and estimates during the period are described in Notes 9, 10, 15 and 19.

Notes to the Unaudited Condensed Consolidated Interim Financial Statements

June 30, 2026 and December 31, 2025

2.2 New and amended IFRS Accounting Standards effective in 2026

Pronouncement		Principal requirement		Effect on the Group
Amendments to IFRS 9 and IFRS 7 - Classification and Measurement of Financial Instruments		Clarify recognition and derecognition dates, the SPPI assessment and disclosures for instruments with contractual terms that can change cash flows.		No material impact identified
Annual Improvements to IFRS Accounting Standards - Volume 11		Amend IFRS 1, IFRS 7, IFRS 9, IFRS 10 and IAS 7.		No material impact identified
Amendments to IFRS 9 and IFRS 7 - Contracts Referencing Nature-dependent Electricity		Amend the own-use and hedge accounting requirements and introduce targeted IFRS 7 disclosures.		No material impact identified
IFRS Interpretations Committee agenda decisions published through June 30, 2026		Include decisions addressing transaction costs under IFRS 9, certain IFRS 16 arrangements and fair presentation under IAS 1.		No material impact identified

2.3 Standards issued but not yet effective

IFRS 18, Presentation and Disclosure in Financial Statements, is effective for annual reporting periods beginning on or after January 1, 2027. The Group is assessing the effects on the structure of the statement of profit or loss, classification of income and expenses, required subtotals, aggregation and disaggregation and disclosures for management-defined performance measures. The Group currently reports EBITDA and adjusted EBITDA measures outside the financial statements and is evaluating whether those measures will meet the definition of management-defined performance measures. IFRS 18 will be applied retrospectively, including to the 2025 and 2026 comparative information presented in the 2027 interim and annual financial statements.

IFRS 19, Subsidiaries without Public Accountability: Disclosures, is also effective from January 1, 2027. The parent company is not eligible to apply IFRS 19 in its consolidated financial statements. The Group is evaluating whether eligible subsidiaries will be permitted to apply the reduced disclosure requirements in their separate financial statements. Such application would not affect the Group’s consolidated financial statements.

IFRS 20, Regulatory Assets and Regulatory Liabilities: In May 2026, the IASB issued IFRS 20, Regulatory Assets and Regulatory Liabilities, which establishes accounting requirements for entities subject to regulatory agreements that determine the amount an entity is entitled to charge customers for goods or services supplied and the timing of when that compensation is included in the amounts charged to customers. IFRS 20 requires an entity within its scope to recognize regulatory assets and regulatory liabilities arising from differences in timing between the recognition of compensation for goods or services supplied and the inclusion of that compensation in the amounts charged to customers. The Standard also establishes requirements for the measurement, presentation and disclosure of regulatory assets, regulatory liabilities, regulatory income and regulatory expense. IFRS 20 is effective for annual reporting periods beginning on or after January 1, 2029, with earlier application permitted, and will replace IFRS 14, Regulatory Deferral Accounts.

Group is currently assessing and identifying all the potential impacts that the adoption of the new standard will have on the consolidated financial statements and notes.

Note 3 - Segment information:

The chief operating decision maker reviews financial information for Cancún, Aerostar, Airplan, ASUR Airports, Mérida, Villahermosa, Services and Other operations. Following the acquisition of ASUR Airports LLC on December 11, 2025, ASUR Airports is presented as a separate reportable segment beginning in 2026 because its results are regularly reviewed separately by the chief operating decision maker and are material to an understanding of the Group’s commercial operations in the United States. Accordingly, there is no corresponding ASUR Airports segment information for the six-month period ended June 30, 2025, as the business was not part of the Group during that period.

Depreciation expense on land, furniture and equipment was Ps$51,825 for the six-month period ended June 30, 2026 (2025: Ps$44,921). Depreciation of right-of-use assets included in this note was Ps$3,669 (2025: Ps$3,526). Total capital expenditures, including concession assets and investment properties, are disclosed in Note 3.

Depreciation expense on land, furniture and equipment was Ps$26,477 for the three-month period ended June 30, 2026 (2025: Ps$22,623). Depreciation of right-of-use assets included in this note was Ps$1,862 (2025: Ps$1,799). Total capital expenditures, including concession assets and investment properties, are disclosed in Note 3.

Note 9 - Investment properties - Net:

Investment properties comprise rights and improvements related to commercial premises operated by ASUR Airports at LAX, ORD and JFK. Right-of-use assets that meet the definition of investment property are presented in this line item and measured subsequently at fair value in accordance with IAS 40. Changes in fair value are recognized in profit or loss. The fair value measurement is classified within Level 3 of the fair value hierarchy.

Component		December 31, 2025				Foreign currency Translation				Net additions / reclassifications				June 30, 2026
Leasehold improvements			843,878				(24,935	)			218,209				1,037,152

Fair value adjustment component			2,824,479				(83,457	)			-				2,741,022
Subtotal - improvements and fair value			4,662,324				(137,761	)			22,448				4,547,011
Right-of-use assets classified as investment property			8,096,625				(239,240	)			(217,161	)			7,640,224
Total investment properties			12,758,949				(377,001	)			(194,713	)			12,187,235

Fair value is determined principally by using discounted cash flow techniques based on contractual rental income, expected occupancy, operating costs, capital expenditures, terminal values and market participant discount rates. Independent external valuation specialists support management’s valuation. The principal unobservable inputs at the latest valuation date were as follows:

Property		Discount rate				Investment horizon (years)
LAX			8.75	%			12.7
ORD			8.75	%			13.7
JFK T1			11.75	%			13.11
JFK T8			9.00	%			11.1

Based on the December 31, 2025 valuation, a one percentage point increase in the discount rates would have decreased the fair value by approximately Ps$781,638, while a one percentage point decrease would have increased the fair value by approximately Ps$646,182. The sensitivity is presented to illustrate the effect of a reasonably possible change and should be updated for the June 30, 2026 valuation if the underlying cash-flow projections or valuation assumptions changed materially.

Notes to the Unaudited Condensed Consolidated Interim Financial Statements

June 30, 2026 and December 31, 2025

There were no potentially dilutive ordinary shares during the periods presented; therefore, basic and diluted earnings per share were the same.

Note 15 - Income taxes:

Income tax expense for the interim period is recognized based on management’s best estimate of the weighted-average annual effective income tax rate expected for the full financial year, applied to the pre-tax income of the interim period. In addition, there were no enacted or substantially enacted tax rates to recognize the remeasurement of deferred tax balances in the interim periods. The estimated annual effective income tax rate reflects the expected mix of taxable income and applicable tax rates in the jurisdictions in which the Group operates, as well as the expected effect of permanent differences, tax incentives and other items affecting the annual effective tax rate. The estimated annual effective income tax rate is reassessed at each interim reporting date based on changes in facts and circumstances and updated expectations for the full financial year.

As of June 30, 2026, the Company operates in Mexico, Colombia, Puerto Rico, and the United States and continues to monitor developments related to the implementation of Pillar Two legislation in these jurisdictions. Based on its assessment, the Company has determined that the Pillar Two rules do not have a material effect on the Company's unaudited condensed consolidated financial position, unaudited condensed consolidated results of operations, or unaudited condensed consolidated cash flows as of and for the six-month period ended June 30, 2026.

For the six-month period ended June 30, 2026, compensation of key management personnel was Ps$126,962 and emoluments to the Board of Directors and committees were Ps$9,293. For the year ended December 31, 2025, short-term compensation of key management personnel was Ps$191,020 and emoluments to the Board of Directors and committees were Ps$12,068.

Management determined that compensation of key management personnel for the six-month periods ended June 30, 2026 and 2025 as a follow:

Transaction		June 30, 2026				December 31, 2025
Short term salaries and other benefits paid to key personal			126,962				191,020
Fees paid to the Board of Directors and Committees			9,293				12,068

Furthermore, there were no material changes in the relevant compensation arrangements or any new material related-party arrangements during the period.

17.2 Proposed acquisition of Companhia de Participações em Concessões

On January 26, 2026, the shareholders authorized the potential acquisition of an equity interest in Companhia de Participações em Concessões ("CPC"), which has interests in airport concessions in Brazil, Ecuador, Costa Rica and Curaçao. The contemplated transaction was expected to be financed principally through debt. As of June 30, 2026, the transaction remained subject to the satisfaction of customary closing conditions and required approvals. Accordingly, no acquisition accounting has been recognized in these condensed consolidated interim financial statements. Subsequent developments are described in Note 21.

Notes to the Unaudited Condensed Consolidated Interim Financial Statements

June 30, 2026 and December 31, 2025

As of June 30, 2026 and 2025, the amount of undiscounted contractual cash flows associated with maturities greater than 5 years of long-term debt including interest amounts to Ps.10,650,000 and Ps.8,846,000, respectively.

As of June 30, 2026 and 2025, the amount of undiscounted contractual cash flows associated with lease liabilities maturing in more than 5 years amounts to Ps.6,411,913 and Ps.6,492,092.

Management monitors forecast and actual cash flows, debt maturities, covenant headroom and available committed facilities. Based on current forecasts, management expects the Group to meet its financial obligations as they fall due for at least twelve months from the authorization date.

At June 30, 2026, the Group held cash and cash equivalents of Ps.11,641,384, comprising Ps.4,748,176 of cash at banks and on hand and Ps.6,893,208 of short-term investments. These amounts represent the Group’s principal financial assets available to meet short-term liquidity requirements. See Note 6.

In addition, Aerostar maintained undrawn committed revolving credit facilities of USD$20 million maturing in December 2026 and USD$10 million maturing in December 2027. See Note 13. The availability of these facilities is subject to compliance with their applicable contractual terms and financial covenants. At June 30, 2026, the Group was in compliance with its financial covenants.

18.3 Credit risk

Credit risk arises principally from passenger charges and other amounts receivable from airlines and commercial counterparties. The Group performs ongoing credit evaluations and recognizes expected credit losses as described in Note 7. Cash and short-term investments are placed with financial institutions that management considers to have adequate credit quality.

18.4 Fair value measurements

The carrying amounts of cash and cash equivalents, trade receivables, trade accounts payable and other short-term financial instruments approximate their fair values because of their short maturities. Bank loans and Short- and Long-Term debt are measured at amortized cost; their fair values are determined using market interest rates and are classified within Level 2 of the fair value hierarchy. Investment properties are measured at fair value within Level 3, as described in Note 9.

As of June 30, 2026, the fair value of financial assets and liabilities is similar to their carrying amounts.

Note 19 - Critical accounting judgments and key sources of estimation uncertainty:

The judgments and estimates that have the most significant effect on the amounts recognized in these condensed consolidated interim financial statements are consistent with those described in the 2025 annual financial statements, except for updates resulting from current-period facts and circumstances. The principal areas are summarized below.

Area		Key judgment or estimate
Revenue recognition and maximum tariff compliance		Determining the timing of satisfaction of performance obligations, estimating discounts and monitoring regulated revenue against maximum tariffs.
Useful life and amortization pattern of the Airplan concession		Estimating the expected pattern of regulated and non-regulated revenue through the concession periods.
Impairment of concessions, commercial rights and goodwill		Forecast passenger traffic, revenue growth, operating margins, discount rates, terminal values and concession terms.
Fair value of investment properties		Projected rents, occupancy, capital expenditures, operating costs, discount rates and investment horizons.
ASUR Airports purchase price allocation		Identifying acquired assets and liabilities and measuring investment properties, lease liabilities, non-controlling interests, deferred taxes and goodwill.
Interim income taxes		Estimating the weighted-average annual effective tax rate and recognizing discrete items and recoverability of deferred tax assets.

Note 20 - Reconciliation of liabilities arising from financing activities:

Movement		Aerostar debt				Bank loans
Opening balance			8,869,864				18,616,699
Interest accrued			239,868				965,751
Interest paid			(244,086	)			(856,763	)
Principal payments			(129,328	)			(323,875	)
Foreign currency translation			(247,074	)			(111,353	)
Closing balance			8,489,244				18,290,459

The reconciliation includes accrued interest and unamortized transaction costs. Lease liability movements are disclosed in Note 11 and should be added to this reconciliation if management concludes that a combined financing-liability reconciliation provides more useful information.

Note 21 - Events after the reporting period:

a) On August 20, 2026, the Company’s shareholders approved a corporate reorganization to integrate into ASUR the technical assistance and technology transfer services currently provided by Inversiones y Técnicas Aeroportuarias, S.A.P.I. de C.V. (“ITA”). The transaction involves entities under common control and is expected to result in the issuance of approximately 7.2 million net new shares of ASUR’s capital stock. The Company does not expect the transaction to have a significant impact on its consolidated financial statements.

b) Management evaluated events occurring after June 30, 2026 through authorization date. As described in Note 17.2, on January 26, 2026, the shareholders authorized the potential acquisition of an equity interest in Companhia de Participações em Concessões ("CPC"), which has interests in airport concessions in Brazil, Ecuador, Costa Rica and Curaçao. Subsequent to June 30, 2026, and prior to the authorization date of these condensed consolidated interim financial statements, the Group completed the acquisition of Motiva Infraestrutura de Mobilidade S.A.'s entire equity interest in CPC on September 1, 2026, following the satisfaction of all conditions precedent under the related purchase agreement. The purchase price amounted to approximately R$5.1 billion (US$992.2 million), subject to customary closing adjustments, and was financed through a loan facility arranged in connection with the acquisition. As a result of the transaction, the Group expanded its airport portfolio through interests in airports located in Brazil, Ecuador, Costa Rica and Curaçao.

As of the authorization date of these condensed consolidated interim financial statements, the determination of the fair values of the identifiable assets acquired and liabilities assumed, as well as the related purchase price allocation, had not been finalized. Accordingly, the accounting for the acquisition remains preliminary and will be completed in accordance with IFRS 3, Business Combinations, during the applicable measurement period. Because the acquisition was completed after June 30, 2026, no amounts related to the acquired business have been recognized in these condensed consolidated interim financial statements.

Except for the matter described above, management identified no events after the reporting period that required adjustment to, or material disclosure in, these condensed consolidated interim financial statements.

Note 22 - Authorization of the financial statements:

These unaudited condensed consolidated interim financial statements and the accompanying notes were authorized and proposed for issuance to the Board of Directors by Lic. Adolfo Castro Rivas, Chief Executive Officer of Grupo Aeroportuario del Sureste, S. A. B. de C. V.

Independent Auditors’ Report on Consolidated Financial Statements

To the Shareholders and management of

Companhia de Participações em Concessões

São Paulo

Report on the Audit of the Consolidated Financial Statements

Opinion

We have audited the consolidated financial statements of Companhia de Participações em Concessões (“the Company”), which comprise the consolidated statement of financial position as at December 31, 2025, the consolidated statements of profit or loss, comprehensive income, changes in equity and cash flows for the year then ended, and notes, comprising material accounting policies and other explanatory information.

In our opinion, the accompanying consolidated financial statements give a true and fair view of the consolidated financial position of the Company as at December 31, 2025, and of its consolidated financial performance and its consolidated cash flows for the year then ended in accordance with IFRS Accounting Standards as issued by the International Accounting Standards Board (IFRS Accounting Standards).

Basis for Opinion

We conducted our audit in accordance with International Standards on Auditing (ISAs). Our responsibilities under those standards are further described in the Auditors’ Responsibilities for the Audit of the Consolidated Financial Statements section of our report. We are independent of the Company in accordance with the ethical requirements that are relevant to our audit of the consolidated financial statements in Brazil, and we have fulfilled our other ethical responsibilities in accordance with these requirements. We believe that the audit evidence we have obtained is sufficient and appropriate to provide a basis for our opinion.

Responsibilities of Management for the Consolidated Financial Statements

Management is responsible for the preparation and fair presentation of the consolidated financial statements in accordance with IFRS Accounting Standards, and for such internal control as management determines is necessary to enable the preparation of consolidated financial statements that are free from material misstatement, whether due to fraud or error.

In preparing the consolidated financial statements, management is responsible for assessing the Company’s ability to continue as a going concern, disclosing, as applicable, matters related to going concern and using the going concern basis of accounting unless management either intends to liquidate the Company or to cease operations, or has no realistic alternative but to do so.

Auditors’ Responsibilities for the Audit of the Consolidated Financial Statements

Our objectives are to obtain reasonable assurance about whether the consolidated financial statements as a whole are free from material misstatement, whether due to fraud or error, and to issue an auditors’ report that includes our opinion. Reasonable assurance is a high level of assurance, but is not a guarantee that an audit conducted in accordance with ISAs will always detect a material misstatement when it exists. Misstatements can arise from fraud or error and are considered material if, individually or in the aggregate, they could reasonably be expected to influence the economic decisions of users taken on the basis of these consolidated financial statements.

As part of an audit in accordance with ISAs, we exercise professional judgment and maintain professional skepticism throughout the audit. We also:

· Identify and assess the risks of material misstatement of the consolidated financial statements, whether due to fraud or error, design and perform audit procedures responsive to those risks, and obtain audit evidence that is sufficient and appropriate to provide a basis for our opinion. The risk of not detecting a material misstatement resulting from fraud is higher than for one resulting from error, as fraud may involve collusion, forgery, intentional omissions, misrepresentations, or the override of internal control.

· Obtain an understanding of internal control relevant to the audit in order to design audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control.

· Evaluate the appropriateness of accounting policies used and the reasonableness of accounting estimates and related disclosures made by management.

· Conclude on the appropriateness of management’s use of the going concern basis of accounting and, based on the audit evidence obtained, whether a material uncertainty exists related to events or conditions that may cast significant doubt on the Company’s ability to continue as a going concern. If we conclude that a material uncertainty exists, we are required to draw attention in our auditors’ report to the related disclosures in the consolidated financial statements or, if such disclosures are inadequate, to modify our opinion. Our conclusions are based on the audit evidence obtained up to the date of our auditors’ report. However, future events or conditions may cause the Company to cease to continue as a going concern.

· Evaluate the overall presentation, structure and content of the consolidated financial statements, including the disclosures, and whether the consolidated financial statements represent the underlying transactions and events in a manner that achieves fair presentation.

· Plan and perform the group audit to obtain sufficient appropriate audit evidence regarding the financial information of the entities or business units within the group as a basis for forming an opinion on the consolidated financial statements. We are responsible for the direction, supervision and review of the audit work performed for purposes of the group audit. We remain solely responsible for our audit opinion.

We communicate with management regarding, among other matters, the planned scope and timing of the audit and significant audit findings, including any significant deficiencies in internal control that we identify during our audit.

Other information

The Company’s concessions consist of the operation of infrastructure projects through the collection of tariffs and revenues arising from the operation of the assets granted, as well as from the rental of areas and commercial spaces. The concessionaires are responsible for constructing, repairing, expanding, preserving, maintaining, and operating the infrastructure under concession, in accordance with the respective concession agreements. The Concession Grantors will transfer to the concessionaires the real estate and other assets in their possession upon execution of the concession agreements. The concessionaires are responsible for ensuring the integrity of the assets transferred to them, as well as for making new investments in the construction or improvement of the infrastructure.

The concession agreements establish annual adjustments to the basic tariffs in accordance with specific formulas set forth therein, which are generally based on inflation indices also specified in the agreements. Although the concession agreements do not include renewal clauses, the concession term may be extended in the event that the economic and financial rebalancing of the agreement executed between the parties is required.

The rights of the concession grantors to terminate the Group’s concession agreements include the unsatisfactory performance of the concessionaire and the material breach of the terms of such agreements.

The Group’s concession agreements may be terminated at the initiative of the concessionaire in the event of non-compliance with contractual standards by the concession grantor, such as the concession grantor’s failure to make payments as established in the agreement, by means of specific legal action filed for such purpose. In this case, the services provided by the Group’s concessionaires may not be interrupted or suspended until a final and unappealable judicial decision is rendered.

Execution of the Share Purchase and Sale Agreement

However, a few highway concession agreements provide for the right to reimbursement relating to the investments necessary to ensure the continuity and adjustment of the services comprised by the concession agreement, provided that they were not depreciated/amortized and the implementation of which, duly authorized by the Concession Grantor, has taken place over the last five years of the concession period.

Notes to the consolidated financial statements for the years ended December 31, 2025 and 2024

(Expressed in thousands of Mexican pesos, unless otherwise indicated)

Use of estimates and judgments

The preparation of the consolidated financial statements requires Management to make judgments, estimates and assumptions that affect the application of accounting policies and the reported amounts for assets, liabilities, revenues and expenses. Actual profit or loss may differ from those estimates.

Estimates and assumptions are periodically reviewed by the Company’s Management, and the changes are recognized prospectively.

Uncertainties regarding assumptions and estimates

Information about uncertainties related to assumptions and estimates at the reporting date that have a significant risk of resulting in a material adjustment to the carrying amounts of assets and liabilities in the next year is included in the notes:

8.1. Expected credit loss: main assumptions for determining credit risk;

9.2. Recognition of deferred tax assets: availability of future taxable profit against which temporary deductible differences and tax losses can be used;

13. Amortization of intangible assets: amortization rate;

16. Provision for labor and social security risks: determination of sufficient value to cover probable estimated losses from ongoing lawsuits; and

20. Financial instruments measured at fair value: premises for measuring fair value, based on observable data.

3. Material accounting policies

The Group has consistently applied the following accounting policies to all periods presented in these consolidated financial statements.

3.1. Consolidation basis

Business combinations

Business combinations are accounted for using the acquisition method when the acquired set of activities and assets meets the definition of a business and control is transferred to the Group.

The Company measures goodwill as the excess of the fair value of the consideration transferred (including the recognized amount of any non-controlling interest in the acquiree) over the fair value of the identifiable assets acquired and liabilities assumed, all measured at the acquisition date. If the resulting amount is negative, a gain on a bargain purchase is recognized immediately in profit or loss.

17

Companhia de Participações em Concessões

Notes to the consolidated financial statements for the years ended December 31, 2025 and 2024

(Expressed in thousands of Mexican pesos, unless otherwise indicated)

In business combinations involving concession arrangements with defined contractual terms, any excess amount attributable to the future economic benefits arising from the concession is allocated to the concession intangible asset and amortized over the concession period, based on the pattern in which the related economic benefits are expected to be consumed.

Transaction costs, other than those associated with the issuance of debt or equity securities, incurred in a business combination are recognized as expenses as incurred.

If the initial accounting for a business combination is incomplete by the end of the reporting period in which the combination occurs, the provisional fair values recognized to date are presented. These provisional amounts are adjusted during the measurement period (one year), or additional assets or liabilities are recognized to reflect new information obtained about facts and circumstances that existed at the acquisition date and, if known, would have affected the amounts recognized at that date.

Subsidiaries and joint ventures

The Company controls an entity when it is exposed to variable returns or has the right over the variable returns that arise from its involvement with the entity, also having the capacity to affect those returns using its power over the entity. The financial statements of the subsidiaries are included in the consolidated financial statements from the time control is obtained until the date it no longer exists.

The financial information of subsidiaries is fully consolidated in the consolidated financial statements.

The Company elected to initially measure any non-controlling interest at its proportionate share of the identifiable net assets of the acquiree at the acquisition date. Changes in the Company’s ownership interest in a subsidiary that do not result in a loss of control are accounted for as equity transactions.

When the entity loses control over a subsidiary, the Company derecognizes the assets and liabilities and any non-controlling interest and other components recorded in equity relating to that subsidiary. Any gain or loss from loss of control is recognized in the statement of profit or loss. If the Group retains any interest in the former subsidiary, that interest is measured at fair value at the date control is lost.

The financial information of joint ventures (ventures over which the Company exercises joint control, directly or indirectly, with one or more investor(s) through a contractual arrangement) are accounted for in the consolidated financial statements using the equity accounting method.

Description of main consolidation procedures

The consolidated financial statements include the financial information of the Company and its direct and indirect subsidiaries, as disclosed in Note 11.

The main consolidation procedures are as follows:

− Elimination of intercompany asset and liability account balances;

− Elimination of equity interests, reserves, and accumulated profits (losses) of the subsidiaries;

− Elimination of intercompany revenues and expenses and unrealized profits arising from transactions conducted by companies that are an integral part of the consolidation;

− Elimination of taxes on the portion of unrealized profits. Unrealized gains (losses) arising from transactions with investees, recognized under the equity accounting method, are eliminated against the investment in proportion to the parent company’s ownership interest in the investee; and

− The interests of non-controlling shareholders, in the shareholders’ equity and in the profit (loss) for the year in subsidiaries, are presented under the line item “Non-controlling interests (NCI)”.

3.2. Foreign currency

Transactions in foreign currency

Monetary assets and liabilities denominated in foreign currency are translated into the Company’s functional currency at the exchange rate prevailing at the end of the reporting year. Non-monetary assets and liabilities purchased or denominated in foreign currency are converted according to the exchange rates prevailing on the transaction dates or on the fair value measurement date, when this is used, and are included in the carrying amounts in Brazilian Reais of these transactions, not being subject to subsequent exchange-rate variation.

Gains and losses from exchange rate variations on the assets and liabilities are recognized in the statement of profit or loss.

Foreign operations

The assets and liabilities of foreign operations, including goodwill and fair value adjustments arising from the acquisition, are translated into Brazilian reais at the exchange rates prevailing at the reporting date. The revenue and expenses of foreign operations are translated into Brazilian reais at the monthly average exchange rate.

(Expressed in thousands of Mexican pesos, unless otherwise indicated)

Foreign currency translation differences are recognized in Other Comprehensive Income and accumulated under the caption Currency translation adjustments in equity. If the subsidiary is not wholly owned, the corresponding portion of the translation difference is attributed to non-controlling interests.

Translation of financial statements from the functional currency to the presentation currency

The financial information of each entity included in the consolidation of CPC’s consolidated financial statements are prepared using the functional currency of the primary economic environment in which it operates. At the entity level, transactions in foreign currencies other than the functional currency of the entity are initially measured using the exchange rates prevailing at the dates of each transaction. Foreign currency monetary items in the statement of financial position are translated using the closing exchange rate as of the reporting date. Foreign exchange gains and losses resulting from the settlement of such transactions and from the remeasurement at period end of foreign currency monetary assets and liabilities are recognized in the consolidated statement of income, under the captions “Finance income” or “Finance expense.” For consolidation purposes, the financial statements of subsidiaries whose functional currency is different from the CPC’s presentation currency are translated into MXN. Assets and liabilities are translated at the exchange rates prevailing at the reporting date, while income and expenses are translated at average exchange rates for the year. Exchange differences arising from the translation of the financial statements of subsidiaries whose functional currency differs from the Group’s presentation currency are recognized in other comprehensive income and accumulated in equity as a cumulative translation adjustment.

3.3. Revenue from agreements with customers

A five-step model for accounting of revenue arising from agreements with customers is applied, so that revenue is recognized at an amount that reflects the consideration to which the entity expects to receive in exchange for the transfer of the assets or services control to a customer.

The five steps mentioned above are: (1) identification of agreements with customers; (2) identification of the performance obligations; (3) determination of transaction price; (4) allocation of transaction price for performance obligations; and (5) revenue recognition.

Airport revenue is recognized when airport services are used by customers.

Ancillary revenue is recognized when the related services are rendered. Revenue from operating leases is recognized on a straight-line basis over the lease term.

Construction revenue: under IFRIC 12, when the concessionaire provides infrastructure construction or improvement services, revenues and costs related to these services are calculated, which are determined according to the stage of completion of the physical progress of the contracted assignment, which is aligned with the measurement of assignments performed.

Tariff values are agreed upon at the conclusion of each concession agreement, which provide for annual readjustments.

The Company also earns revenue from the provision of administrative services to other non-controlled companies within the Group and recognizes such revenue as the services are rendered.

Revenues are not recorded if there is significant uncertainty as to their realization.

See note 18 for further details.

3.4. Financial instruments

Initial recognition and measurement

Accounts receivable and debt securities are initially recognized on the date they originated. All other financial assets and liabilities are initially recognized when the Group becomes one of the parties to the contractual provisions of the instrument.

A financial asset (unless in the case of trade receivables from customers without a significant financing component) or a financial liability is initially measured at fair value, plus or minus, for an item not measured at fair value through profit or loss (FVTPL), the transaction costs that are directly attributable to its acquisition or issuance. Trade receivables without a significant financing component are initially measured at the transaction price.

Subsequent classification and measurement

Financial assets

In initial recognition, a financial asset is classified as measured: at amortized cost; or at FVTPL.

21

Companhia de Participações em Concessões

Notes to the consolidated financial statements for the years ended December 31, 2025 and 2024

(Expressed in thousands of Mexican pesos, unless otherwise indicated)

Financial assets are not subsequently reclassified after their initial recognition unless the Group changes its business model for managing financial assets, in which case all affected financial assets are reclassified on the first day of the reporting period following the change in the business model.

A financial asset is measured at amortized cost if it meets both of the following conditions and is not designated as measured at FVTPL:

· it is maintained within a business model whose objective is to hold financial assets in order to collect contractual cash flows; and

· its contractual terms generate, on specific dates, cash flows related only to payment of principal and interest on the outstanding principal amount.

All financial assets not classified as measured at amortized cost, as described above, are classified as FVTPL. This includes all derivative financial assets. At initial recognition, the Group may irrevocably designate a financial asset that would otherwise meet the requirements to be measured at amortized cost as at FVTPL if doing so eliminates or significantly reduces an accounting mismatch that would otherwise arise.

Financial assets - Assessment of the business model

The Group assesses the objective of the business model in which a financial asset is held in a portfolio because this best reflects how the business is managed and how information is provided to Management. The information considered includes:

· the policies and goals established for the portfolio and the practical functioning of such policies. They include whether Management’s strategy focuses on obtaining contractual interest revenue, maintaining a certain interest rate profile, matching the duration of financial assets with the duration of related liabilities or expected cash outflows, or the realization of cash flows through the sale of assets;

· how the portfolio’s performance is evaluated and reported to the Group’s Management;

· the risks that affect the performance of the business model (and the financial asset held in that business model) and the way those risks are managed;

· how business managers are remunerated, for example, whether the remuneration is based on the fair value of the assets managed or on the contractual cash flows obtained; and

· the frequency, volume, and timing of sales of financial assets in prior periods, the reasons for such sales, and expectations for future sales.

Notes to the consolidated financial statements for the years ended December 31, 2025 and 2024

(Expressed in thousands of Mexican pesos, unless otherwise indicated)

Transfers of financial assets to third parties in transactions that do not qualify for derecognition are not considered sales, consistent with the Group’s continuing recognition of the assets.

Financial assets held for trading or managed with performance measured at fair value are measured at fair value through profit or loss.

Financial assets – Assessment of whether contractual cash flows are only payments of principal and interest

For the purposes of such assessment, “principal” is defined as the fair value of a financial asset upon initial recognition. “Interest” is defined as a consideration for the value of money over time for the credit risk associated with the outstanding principal over a given period and for the other basic risks and costs of loans (for example, liquidity risk and administrative costs), as well as a profit margin.

The Group considers the contractual terms of the instrument to assess whether the cash flows are solely payments of principal and interest. This includes assessing whether the financial asset contains a contractual term that could change the timing or value of contractual cash flows so that it would not meet this condition. In making this assessment, the Group considers:

· contingent events that change the value or timing of cash flows;

· terms that may adjust the contractual rate, including variable rates;

· prepayment and extension of the term; and

· terms that limit the Group’s access to cash flows from specific assets (for example, based on the performance of an asset).

Prepayment is consistent with the payment criterion of principal and interest if the prepayment amount represents, in the most part, unpaid amounts of principal and interest on the outstanding amount of principal— which may include reasonable compensation for the early termination of the contract. Furthermore, in relation to a financial asset acquired at a value lower or greater than the nominal value of the agreement, the authorization or requirement of prepayment at a value representing the nominal value of the agreement plus contractual interest accrued (but unpaid) (which may also include reasonable offsetting for anticipatory termination of the agreement) are treated as consistent with this criterion if the fair value of the prepayment is insignificant at the initial recognition.

Financial assets – Subsequent measurement and gains and losses

Financial assets at amortized cost	These assets are subsequently measured at amortized cost using the effective interest method. The amortized cost is reduced by impairment losses. The revenue from interest, exchange gains and losses, and impairment are recognized in the statement of profit or loss. Any gain or loss on derecognition is recognized in the statement of profit or loss.
Financial assets at FVTPL	These assets are subsequently measured at fair value. Net profit or loss, including interest, is recognized in the statement of profit or loss.

Derecognition

Financial assets

The Group derecognizes a financial asset when:

· the contractual rights to the cash flows from the asset expire; or

· it transfers the contractual rights to receive the contractual cash flows on a financial asset in a transaction where:

· all the risks and benefits of ownership of the financial asset are substantially transferred; or

· the Group neither transfers nor retains substantially all the risks and rewards of ownership of the financial asset and does not retain control over the financial asset.

The Group enters into transactions in which it transfers assets recognized in the balance sheet but retains all or substantially all of the risks and rewards of the transferred assets. In such cases, financial assets are not derecognized.

Financial liabilities

The Group derecognizes a financial liability when its contractual obligations are discharged, cancelled, or expire. The Group also derecognizes a financial liability when its terms are modified and the cash flows of the modified liability are substantially different, in which case a new financial liability based on the modified terms is recognized at fair value.

24

Companhia de Participações em Concessões

Notes to the consolidated financial statements for the years ended December 31, 2025 and 2024

(Expressed in thousands of Mexican pesos, unless otherwise indicated)

Upon the derecognition of a financial liability, the difference between the terminated carrying amount and the consideration paid (including transferred assets that do not transit through the cash or liabilities assumed) is recognized in the statement of profit or loss.

Hedge accounting

The Company designates certain hedging instruments related to foreign currency and interest rate risk as fair value hedges or cash flow hedges.

At the beginning of the hedging relationship, the Company documents the relationship between the hedging instrument and the hedged item, along with its risk management objectives and its strategy for undertaking various hedging transactions. Additionally, at the inception of the hedge and on an ongoing basis, the Company documents whether the hedging instrument used in a hedging relationship is highly effective in offsetting changes in the fair value or cash flow of the hedged item attributable to the hedged risk.

Note no. 20 provides further details on the fair value of derivative instruments used for hedging purposes.

Cash flow hedge: hedge of the exposure to variability in cash flows that is attributable to a particular risk associated with a recognized asset or liability (such as all or some of the future interest payments on a variable-rate debt) or a highly probable anticipated transaction that could affect profit or loss.

The effective portion of changes in the fair value of derivatives that is designated and qualified as a cash flow hedge is recognized in other comprehensive income and accumulated in the cash flow hedge item, in equity, and is limited to the cumulative change in the fair value of the hedged item, determined on a present value basis, since the inception of the hedge. Losses or gains related to the ineffective portion are recognized immediately in the profit or loss for the period.

Amounts previously recognized in other comprehensive income and accumulated in equity are reclassified to profit or loss in the period in which the hedged item is recognized in profit or loss, under the same heading in the income statement in which such item is recognized.

Hedge accounting is discontinued when the Company cancels the hedging relationship, the hedging instrument expires or is sold, terminated, or enforced, or when it no longer qualifies as hedge accounting.

When the hedged transaction is no longer expected to occur, the accumulated and deferred gains or losses in equity are recognized immediately in profit or loss.

(Expressed in thousands of Mexican pesos, unless otherwise indicated)

Offsetting

Financial assets and liabilities are offset and the net amount is presented in the balance sheet when, and only when, the Group currently has a legally enforceable right to offset the amounts and intends either to settle them on a net basis or to realize the asset and settle the liability simultaneously.

3.5. Cash and cash equivalents and financial investments

Cash and cash equivalents

Cash and cash equivalents encompass the balances of cash and immediately convertible financial investments with insignificant risk of change in value. These funds are kept for the purpose of meeting short-term commitments.

In addition to the criteria above, the projected resource outflows for the next 3 months from the date of the evaluation are used as a classification parameter.

Financial investments

Financial investments comprise financial assets whose expected realization exceeds three months from the acquisition date, or that are not readily available for general use, and therefore do not qualify for classification as cash and cash equivalents.

3.6. Transaction cost in the issuance of debt securities

Costs incurred to raise funds from third parties are initially deducted from the carrying amount of the related financial liability and subsequently recognized in profit or loss as the term elapses, based on the amortized cost method, which considers the Effective Interest Rate (EIR) of the transaction to appropriate financial charges during the term of the transaction. The internal return rate takes into account all cash flows, from the net present value of the transaction through all payments made or to be made, for the settlement of the transaction.

3.7. Property, plant, and equipment

Recognition and measurement

Property, plant, and equipment are measured at the historical cost, including acquisition and construction costs, less accumulated depreciation and any accumulated impairment losses, when necessary.

26

Companhia de Participações em Concessões

Notes to the consolidated financial statements for the years ended December 31, 2025 and 2024

(Expressed in thousands of Mexican pesos, unless otherwise indicated)

The costs of property, plant, and equipment are composed of expenditures that are directly attributable to the acquisition/construction of the assets, including the costs of materials, direct labor, and any other costs to place the asset in the location and condition necessary for it to operate. Additionally, for qualified assets, loan costs are capitalized.

When parts of an item of property, plant, and equipment have different useful lives, they are accounted for as individual items (major components) of property, plant, and equipment.

Other expenditures are capitalized only when there is an increase in the future economic benefits of the item of property, plant, and equipment to which it refers; if not, it is recognized in the statement of profit or loss as expenses.

Gains and losses on disposal of an item of property, plant, and equipment determined by comparing the proceeds from disposal with the carrying amount of the same are recognized in the statement of profit or loss as other operating revenues/expenses.

The replacement cost of a property, plant, and equipment component is recognized as such when it is probable that future economic benefits are embodied in it and its cost can be reliably measured. The carrying amount of a component replaced by another is written off. The maintenance costs are recognized in the statement of profit or loss when incurred.

Depreciation

Depreciation is calculated using the straight-line basis, at the rates compatible with the economic useful life and/or concession period, whichever is shorter. The useful lives are shown in note 12.

The depreciation methods, useful lives, and residual values are reviewed at the end of each year and potential adjustments are recognized as changes in accounting estimates.

3.8. Intangible assets

The Company has the following intangible assets:

· Software licenses and development costs

These assets are measured at cost less accumulated amortization and accumulated impairment losses, if any. Amortization is recognized on a straight-line basis over their estimated useful lives.

27

Companhia de Participações em Concessões

Notes to the consolidated financial statements for the years ended December 31, 2025 and 2024

(Expressed in thousands of Mexican pesos, unless otherwise indicated)

· Infrastructure exploration rights – see Note 3.14.

Assets under construction are classified as Construction in Progress.

3.9. Impairment of assets

Non-derivative financial assets

The Group recognizes allowances for expected credit losses on financial assets measured at amortized cost.

Expected credit losses with a significant financing component are measured over 12 months, unless credit risk has increased significantly, in which case losses allowances are measured over the entire life of the asset.

Expected credit losses for 12 months are credit losses that result from potential default events within 12 months after the reporting date (or in a shorter period if the expected life of the instrument is less than 12 months).

Provisions for losses regarding trade receivables without a significant component of financing are measured at a value equal to a credit loss estimated for the instrument’s entire life, which derives from all possible default events throughout the financial instrument’s expected life.

The maximum period considered in estimating expected credit losses is the maximum contractual period over which the Group is exposed to credit risk.

In determining whether the credit risk of a financial asset has increased significantly since initial recognition and in estimating expected credit losses, the Group considers reasonable and supportable information that is relevant and available without undue cost or effort. This includes quantitative and qualitative analyses based on the Group’s historical experience, credit assessment, and consideration of forward-looking information (forward-looking).

Expected credit losses are estimates weighted by the probability of credit losses. When applicable, credit losses are measured at present value, based on the difference between the cash flows due to the Group in accordance with the agreement and the cash flows the Group expects to receive. The expected credit losses are discounted by the effective interest rate of the financial asset.

28

Companhia de Participações em Concessões

Notes to the consolidated financial statements for the years ended December 31, 2025 and 2024

(Expressed in thousands of Mexican pesos, unless otherwise indicated)

The gross carrying amount of a financial asset is written off when the Group has no reasonable expectation of recovering the financial asset in full or in part. However, financial assets written off may still be subject to collection activities to comply with the Group’s procedures for recovering amounts due.

The loss allowance for financial assets measured at amortized cost is deducted from the gross carrying amount of the assets and charged to profit or loss.

Non-financial assets

The carrying amounts of non-financial assets are reviewed annually to determine if there is an indication of impairment loss. For impairment testing purposes, assets are grouped into cash-generating units (CGUs), and, if any such indication exists, the recoverable amount of the respective CGU is estimated.

The Group determines an asset’s value in use based on the present value of expected cash flow projections, based on budgets approved by Management, as of the valuation date and through the end of the concession term, considering discount rates that reflect the specific risks associated with each cash-generating unit.

During the projection period, the key assumptions considered are related to estimates of traffic for the infrastructure projects held, indices used to adjust tariffs, growth in Gross Domestic Product (GDP) and the respective GDP elasticity of each business, operating costs, inflation, capital expenditures, discount rates, and contractual rebalancing.

An impairment loss is recognized in the statement of profit or loss when the carrying amount of an asset exceeds its estimated recoverable amount.

The recoverable value of an asset is the higher between its value in use and its fair value less costs of disposal. The value in use is based on estimated future cash flows discounted to present value using a discount rate before taxes that reflects current market evaluations of the value of money over time and the specific risks of the asset.

At the end of each reporting period, the Group assesses whether there is any indication that previously recognized impairment losses may no longer exist or may have decreased. An impairment is reversed in case of changes in the estimates used to determine the recoverable value, only to the extent that the asset’s carrying amount does not exceed the carrying amount that would have been determined, less depreciation or amortization, had no impairment been recognized.

(Expressed in thousands of Mexican pesos, unless otherwise indicated)

3.10. Provisions

A provision is recognized in the balance sheet when the Company has a legal or unformalized obligation incorporated as a result of a past event, which can be reliably estimated, and it is probable that economic resources will be required to settle the obligation. Provisions are calculated by discounting the expected future cash flows at a pre-tax rate which reflects the current market evaluations as to the value of the cash over time and the specific risks of the liability. The financial costs incurred are recorded in the statement of profit or loss.

3.11. Financial revenues and expenses

Financial revenue basically comprises interest from financial investments, changes in the fair value of financial assets, which are recorded through the profit or loss for the year, and positive adjustments for inflation and exchange rate variations on financial instruments, whether classified as assets or liabilities.

Financial expenses basically comprise interest, inflation adjustments and exchange-rate variations on financial liabilities, rearrangement of adjustments to present value on provisions, and changes in the fair value of financial assets measured at fair value through profit or loss. Loan costs that are not directly attributable to the acquisition, construction, or production of qualifying assets are recognized in the statement of profit or loss for the year using the effective interest method.

3.12. Employee benefits

Defined contribution plans

A defined contribution plan is a post-employment benefit plan under which an entity pays fixed contributions to a separate entity (pension fund) and will have no obligation to pay further amounts. Obligations for contributions to defined contribution pension plans are recognized as employee benefit expenses in the statement of profit or loss, for the periods in which the services are rendered by the employees.

Short-Term Employee Benefits

Short-term employee benefit obligations are measured on an undiscounted basis and are recorded as expenses as the related service is provided.

Notes to the consolidated financial statements for the years ended December 31, 2025 and 2024

(Expressed in thousands of Mexican pesos, unless otherwise indicated)

3.13. Income tax and social security contributions

Current and deferred income tax and social contribution are calculated based on the tax rates of 15% plus a surcharge of 10% on taxable profit in excess of BRL 240 (annual basis – equivalent to MXN 824) for income tax and 9% on taxable profit for social security contribution on net income, considering the offsetting of tax losses and negative basis of social security contribution limited to 30% of the taxable profit.

Current and deferred taxes are recognized in the statement of profit or loss unless they are related to items recognized directly in equity.

Current taxes are the taxes payable on the taxable profit for the year, at rates effective on the date of consolidated financial statements.

Deferred taxes are recognized in relation to temporary differences between the carrying amounts of the assets and liabilities for accounting purposes, and the corresponding amounts are used for taxation purposes. Deferred tax assets and liabilities are measured based on tax rates that are expected to be applied to the temporary differences when they are reversed, based on tax rates that were decreed up to the reporting date, which reflect the uncertainty related to tax on profit, if any.

To determine current and deferred income tax, the Company takes into consideration the impact of uncertainties on positions taken on taxes and if the additional income tax and interest payment should be made. The Company believes that the provision for income tax recorded in liabilities is adequate for all outstanding years, based on its evaluation of several factors, including interpretations of tax laws and past experience. This evaluation is based on estimates and assumptions that may involve a range of judgments on future events. New information may be provided, making the Company change its judgment on the adequacy of the existing provision; such changes will impact income tax expenses for the year in which they are made. Deferred tax assets and liabilities are offset when there is a legally enforceable right to compensate current tax assets and liabilities, and the latter relate to income taxes levied by the same tax authority on the same taxable entity subject to taxation.

A deferred income tax and social security contribution asset is recognized for tax losses, negative bases, and deductible temporary differences, to the extent that it is probable that future taxable profit will be available against which these can be used, such use being limited to 30% of future annual taxable profit.

Deferred tax assets arising from temporary differences consider the expected generation of future taxable profit, based on a technical feasibility study approved by management, which includes assumptions that are affected by expected future conditions of the economy and the market, in addition to assumptions of growth in the revenue arising from each operating activity of the Company, which may be impacted by economic reductions or growth, expected inflation rates, traffic volume, among others.

31

Companhia de Participações em Concessões

Notes to the consolidated financial statements for the years ended December 31, 2025 and 2024

(Expressed in thousands of Mexican pesos, unless otherwise indicated)

Deferred tax is not recognized for:

· temporary differences on the initial recognition of assets and liabilities in a transaction that is not a business combination, and which does not affect the taxable profit or loss, nor the accounting result; and

· temporary taxable differences arising from the initial recognition of goodwill.

3.14. Service concession agreements – Infrastructure operation right (IFRIC 12)

The infrastructure, within the scope of Technical Interpretation IFRIC 12 - Concession Agreements, is not recognized as the concessionaire’s property, plant, and equipment, since the concession agreement sets forth only the transfer of ownership of these assets for the provision of public services, and they are handed over to the Concession Grantor after the termination of the relevant agreement. The concessionaire has access to construct and/or operate the infrastructure for the provision of services for a specified period under the concession agreement.

Under the terms of the concession agreements in the scope of IFRIC 12, the concessionaire is a service renderer, building or improving the infrastructure (construction or improvement services) used to provide a public service and operates and maintains this infrastructure (operation services) during a determined period.

If the concessionaire provides construction or improvement services, received or receivable remuneration is recorded at fair value. This remuneration may correspond to a right over an intangible asset, financial asset, or both. The Concessionaire recognizes an intangible asset to the extent it receives the right (authorization) to charge the users for the provision of public services. The Concessionaire recognizes a financial asset to the extent that it has the unconditional contractual right to receive cash or another financial asset from the Concession Grantor for the construction services.

Such financial assets are measured at their fair value on initial recognition and then measured at amortized cost.

Should the Company be partially remunerated for the construction services through a financial asset and partially through an intangible asset, each item of the remuneration received or receivable is individually registered, and it is initially recognized at the fair value of the remuneration received or receivable.

32

Companhia de Participações em Concessões

Notes to the consolidated financial statements for the years ended December 31, 2025 and 2024

(Expressed in thousands of Mexican pesos, unless otherwise indicated)

The infrastructure operation right results from expenses on construction works for improvements in exchange for the right to charge users for the use of the infrastructure. This right is comprised of construction cost plus profit margin and loan costs attributable to this asset. The Company estimated that any margin, net of taxes, is immaterial, considering it as zero.

The infrastructure exploration right may also arise from payments to the Granting Authority in exchange for the right to charge users for the use of the infrastructure, such as the existing concessions at BH Airport, Bloco Sul, Bloco Central and Pampulha.

Expenditures incurred in the performance of improvement construction works that do not generate future economic benefits are recorded as costs when incurred, as they do not meet the criteria for recognition of intangible assets.

Because concession agreements are subject to execution, construction of infrastructure improvement works are only recognized in the accounting records when they are physically executed.

Additionally, the Company accountably recognizes the non-monetary assets from the concession agreements entered into with the Concession Grantors related to the extension of terms resulting from economic rebalancing, according to the characteristics mentioned above, as intangible assets at its fair value, since there is no associated performance obligation, as intangible assets, the corresponding entry being revenue in the profit or loss. Regarding the amount registered in the profit or loss, deferred tax liabilities are constituted, originating from the temporary difference.

Amortization of the infrastructure exploration right is recognized in profit or loss based on the expected economic benefit curve over the concession term, taking into consideration the estimated curve of airport passenger traffic as the basis for amortization.

3.15. Segment information

Segment information is presented in accordance with IFRS 8 – Segment Information.

The Company’s Management in place at the reporting date, appointed by the Motiva Group and acting as the Chief Operating Decision Maker (“CODM”), regularly reviewed the Company’s operational and financial information for purposes of performance assessment and resource allocation.

Based on the information reviewed by the CODM as of the reporting date, the Company operated in a single operating segment, consisting of airport concession activities. Therefore, segment information is presented on a consolidated basis.

3.16. New standards not yet in effect

Certain new standards will become effective for periods ending after January 01, 2026, and have not been adopted in the preparation of these consolidated financial statements.

Presentation and disclosure of consolidated financial statements

IFRS 18 will replace IAS 1 – Presentation of Financial Statements and applies to annual reporting periods beginning on or after January 1, 2027. The new standard introduces the following key new requirements:

· Entities are required to classify all income and expenses into five categories in the statement of profit or loss: operating, investing, financing, discontinued operations, and income tax. Entities are also required to present a newly defined operating profit subtotal. Entities’ net profit will not change.

· Management-defined performance measures (MPMs) are disclosed in a single note to the financial statements.

· Enhanced guidance is provided on how to group information in the financial statements.

Additionally, all entities are required to use the operating profit subtotal as the starting point for the statement of cash flows when presenting operating cash flows using the indirect method.

The Group is still in the process of assessing the impact of the new standard, particularly with respect to the structure of the Group’s statement of profit or loss, statement of cash flows, and additional disclosures required for MPMs. Entities are required to classify all revenues and expenses into five categories in the Statement of Profit or Loss, namely: operating, investing, financing, discontinued operations, and income tax.

Other accounting standards

The following amended standards are not expected to have a significant impact on the consolidated financial statements:

· Nature-related electricity agreements (amendments to IFRS 7 and IFRS 9); and

· Classification and Measurement of Financial Instruments (amendments to IFRS 7 and IFRS 9).

3.18. Tax reform

On December 20, 2023, Constitutional Amendment No. 132 was enacted, establishing the Consumption Tax Reform based on the Dual VAT model: the Contribution on Goods and Services (CBS - Federal) and the Tax on Goods and Services (IBS - Subnational).

On January 16, 2025, Complementary Law No. 214/2025 (originating from PLP 68/2024) was enacted, regulating the main provisions of the new regime and the Excise Tax (IS).

34

Companhia de Participações em Concessões

Notes to the consolidated financial statements for the years ended December 31, 2025 and 2024

(Expressed in thousands of Mexican pesos, unless otherwise indicated)

On April 30, 2026, Decree No. 12,955/2026 was published, regulating the CBS, providing, among other aspects, for the incidence, calculation basis, and passive subjection, as well as the operational rules applicable to the federal tax.

The transition to the new system will take place between 2026 and 2032. Given the current transition phase and the dependence on regulatory definitions, the quantitative effects of the Reform on the calculation of taxes cannot yet be estimated with precision. Consequently, there were no measurable impacts on these consolidated financial statements as of December 31, 2025.

Management notes that the concession agreements operated by the Group provide for economic and financial rebalancing arising from impacts on revenue. Therefore, any increases in tax costs resulting from the transition shall be subject to economic and financial rebalancing.

3.19 Share-based payment

Share-based payments, payable in shares, are accounted for at the fair value of the equity instruments granted at the grant date. This cost is recognized over the vesting period of the instruments.

4. Determination of fair values

A number of the Company’s accounting policies and disclosures require the determination of fair value, for both financial and non-financial assets and liabilities. Fair values have been determined for measurement and/or disclosure purposes, based on the following methods. When applicable, additional information about the assumptions made in determining fair values is disclosed in the notes specific to that asset or liability.

· Cash and banks

The fair values of these financial assets are equal to the carrying amounts, considering their immediate liquidity.

· Financial investments

The fair value of financial assets measured at fair value through profit or loss is determined by reference to their closing prices on the date of recognition of financial statements.

(Expressed in thousands of Mexican pesos, unless otherwise indicated)

· Non-derivative financial liabilities

The fair value determined for accounting and/or disclosure purposes is calculated based on the present value of projected future cash flows. The rates used in calculations were obtained from public sources (B3 and Bloomberg).

The Company uses observable market data as much as possible to measure the fair value of an asset or a liability. Fair values are classified at different levels in a hierarchy based on inputs used in valuation techniques in the following way. The different levels are defined below:

· Level 1: (non-adjusted) prices traded in active markets for identical assets and liabilities;

· Level 2: inputs, other than prices traded in active markets included in tier 1, that are observable for the asset or liability, either directly (prices) or indirectly (derived from prices); and

· Level 3: assumptions, for assets or liabilities, which are not based on observable market data (non-observable inputs).

5. Financial risk management

5.1 Overview

The Company is exposed to the following risks:

a) Credit risk;

b) Interest rates and inflation risk;

c) Foreign exchange rate risk; and

d) Financial risk and liquidity.

Information on the Company’s exposure to each of the abovementioned risks, the goals, policies, and processes for measuring and managing risk and capital is presented below. Additional quantitative disclosures are included throughout these consolidated financial statements.

a. Credit risk

Credit risk arises from the possibility that the Company and its subsidiaries may incur losses resulting from default by counterparties or financial institutions that hold cash and cash equivalents or financial investments. To mitigate these risks, the Group adopts as a practice the analysis of the financial and equity position of its counterparties, as well as the establishment of credit limits and ongoing monitoring of outstanding positions, except for accounts receivable from Concession Grantors, which are primarily subject to concession risk. As regards financial institutions, operations are only carried out with low-risk financial institutions, assessed by rating agencies. Further details in this regard can be found in Notes 7, 8, 10, 14, 15, and 20.

Notes to the consolidated financial statements for the years ended December 31, 2025 and 2024

(Expressed in thousands of Mexican pesos, unless otherwise indicated)

b. Interest rates and inflation risk

Arises from the possibility of reduced gains or increased losses arising from oscillations in interest rates on its financial assets and liabilities.

The Company and its subsidiaries are exposed to floating interest rates, primarily related to variations in: (1) the Long-Term Interest Rate (TJLP) and the Interbank Deposit Certificate (CDI) applicable to borrowings in Brazilian reais; (2) the General Market Price Index (IGP-M), the Broad Consumer Price Index (IPCA), and the CDI applicable to debentures; and (3) the IGP-M and IPCA applicable to the concession term. The interest rates of financial investments are mainly linked to the CDI rate variation. Further details in this regard can be found in Notes 7, 10, 14, 15, and 20.

The Group’s concession tariffs are adjusted based on inflation indices.

c. Exchange rate risk

This risk arises from the possibility of fluctuations in the exchange rates of foreign currencies used for the acquisition of equipment and supplies abroad, as well as for the settlement of financial liabilities. In addition to amounts payable and receivable in foreign currencies, the Company has investments in subsidiaries and joint ventures abroad and has cash flows from purchases and sales in other currencies. The Company, its subsidiaries, and joint ventures continually assess whether to enter into hedging transactions to mitigate these risks.

The investees finance part of their operations through loans and financing denominated in foreign currencies linked to the U.S. dollar (USD) equivalent, as of December 31, 2025.

For further details, see Notes 14 and 20.

d. Financial risk and liquidity

This risk arises from the choice between equity financing (capital contributions and retained earnings) and third-party capital used by the Company and its subsidiaries to finance their operations. Liquidity risk is the risk that the Group will encounter difficulties in meeting obligations associated with financial liabilities that are settled through cash payments or the delivery of another financial asset. To mitigate liquidity risks and optimize the weighted average cost of capital, the Group monitors investment and indebtedness levels in accordance with market standards and compliance with covenants set forth in loan, financing, and debenture agreements. Management believes that the Company and its subsidiaries have the capacity to maintain business continuity under normal operating conditions.

11.4 Other relevant information – Legal, administrative-regulatory, and arbitration proceedings related to concession agreements issues

The Company and its subsidiaries are parties to legal, administrative-regulatory, and arbitration proceedings related to concession agreements matters.

In the context of concessions in general, administrative-regulatory proceedings are the formal instruments through which interaction between concessionaires and Concession Grantors occurs (such as a service provider relationship with the customer) regarding various topics relating to the concession agreements, covering, but not limited to, matters that affect the contractual interpretation and the economic-financial balance of the concession. Such administrative-regulatory proceedings can be initiated by either party, and technical, regulatory, contractual, and legal topics of different natures regarding the dynamics of the concession are presented and discussed. During their course, such proceedings bring preliminary or non-definitive positions regarding the legal expectations of each requesting party. Administrative decisions must be made in compliance with the governing legislation and the concession agreements themselves and, in general, may be subject to judicial or arbitration review.

The nature of these contractual discussions typically involves tariff adjustments, force majeure events (i.e., COVID-19 pandemic), changes to the time of execution or scope of the construction works provided for in the concession agreements, controversies regarding compliance or non-compliance with specific contractual requirements, or even the form of measurement.

There are uncertainties related to the measurement of regulatory proceedings, including: (i) the understanding of each party on the topic, (ii) negotiations or their subsequent developments, which substantially alter the amounts involved, (iii) the complexity of measurement, which commonly involves technical expertise, (iv) the high probability of different issues being evaluated and resolved jointly, based on the respective net balance of the recognized claims of each party, and (v) the form of settlement.

Final resolutions on regulatory issues can occur in different, non-exclusive ways, such as: (i) receipt or payment in cash, (ii) extension or reduction of the concession agreement term, and (iii) reduction or increase of commitment to future investments, increase or reduction of the tariff.

Furthermore, rebalancing received in the form of a tariff increase or reduction is recognized as the service is provided by the concessionaire, as well as rebalancing in the form of a reduction or increase in future investment commitments, which, being executory agreements, will be recognized with the realization of the infrastructure improvement construction work. Management reiterates its confidence in the current legal procedures applicable to concession agreements and assesses the risk of loss of discussions related to regulatory matters of the agreements as being remote and/or with no expectation of cash disbursement.

Retention Portion

The fair value of the portion linked to the retention, consisting of 31,217 shares, was determined by the market price of the Motiva’s shares, on April 16, 2025 (grant date), of MXN 41.99, and is conditional only on the passing of time and the provision of the service by employees.

The plans granted in 2023 and 2024 maintain the same characteristics disclosed in the explanatory notes to the financial statements for the year ended on December 31, 2024, and 2023. In the first half of 2025, 32,371 shares were granted, and 287,302 shares were canceled due to terminations, leaving 58,876 shares to be exercised as the vesting period progresses.

In the fiscal year period ended December 31, 2025, the amount of MXN 3,238 related to the plans granted in 2023, 2024, and 2025 was reversed from an expense, with a corresponding entry to capital reserve.

Settlement of share-based payment awards

In connection with the sale transaction of CPC, concluded on September 1, 2026 (see note n. 1), the following settlement conditions apply to the outstanding long-term incentive plans:

· Lock-up: The one-year lock-up restriction is released upon closing of the transaction.

· Retention Tranche (50% of each grant): Motiva’s shares will be transferred to the beneficiaries at closing, with immediate settlement, regardless of the originally established vesting schedule.

· Performance Tranche (50% of each grant): Settlement remains subject to the measurement and achievement of the applicable TSR index. The vesting periods are accelerated and deemed fulfilled as of the closing date; however, the actual transfer of shares is contingent upon confirmation that the TSR target has been met, and this tranche remains restricted until the index is determined.

· Share transfer (2023, 2024 and 2025 grants): Settled through the transfer of shares at closing, under the conditions described above.

The lock-up release process has been initiated, with the share transfer expected to take place in October 2026.

(a) Carrying amounts are gross from transaction costs.

Loans and Debentures Measured at Amortized Cost - If the criterion of recognizing these liabilities at their fair value (Level 2) were adopted, the resulting balances would be as follows:

		Consolidated
		12/31/2025								12/31/2024
		Carrying amount				Fair value				Carrying amount				Fair value
Debentures (a)			15,298,505				14,940,398				14,395,221				13,609,035
Loans and financing (a)			4,796,018				4,748,654				4,704,250				5,956,821

(a) Carrying amounts are gross from transaction costs.

Fair values were calculated by projecting cash flows up to the maturity of the transactions based on future rates obtained from public sources (e.g., B3, ANBIMA, and Bloomberg), adding contractual spreads and brought to present value using a pre-fixed rate (pre-DI), plus credit risk components, which considers the ANBIMA triple-A credit curve on the base date as the spread.

20.2 Derivative financial instruments

The main purpose of the operations conducted as of December 31, 2025, is to protect against fluctuations in other indexes and interest rates, without a speculative nature. Accordingly, they are characterized as hedge instruments and recorded at fair value through profit or loss.

The Company contracted and settled NDF (Non-Deliverable Forward) for protection against exchange-rate variation in relation to open balances with supplier Alstom.

All derivative financial instruments were traded over-the-counter (OTC).

20.3 Sensitivity analysis

Sensitivity analyses are established based on assumptions and premises related to future events. The Management of the Company and its subsidiaries regularly review these estimates and assumptions used in calculations. However, the settlement of transactions involving these estimates may result in amounts that differ from estimated amounts, as a result of the subjectivity inherent to the process used to prepare the analyses.

In the sensitivity analysis calculations, new contracts of operations with derivatives were not considered other than the current ones.

For the A and B stress scenarios of the sensitivity analysis, the Company adopted the percentages of 25% and 50%, respectively, which are applied to present the situation showing relevant sensitivity to variable risk.

20.3.1 Sensitivity analysis of interest rate variations

The table below presents the amounts arising from foreign exchange variations and interest on loan, financing, debenture, intercompany loan, bond, and other financial instrument agreements with post-fixed rates, within the 12-month period, i.e., through December 31, 2026, or through the maturity date of each transaction, whichever occurs first.

Independent Auditors’ Report on Review of Consolidated Interim Financial Information

To the Shareholders and management of

Companhia de Participações em Concessões

São Paulo

Introduction

We have reviewed the accompanying consolidated statement of financial position of Companhia de Participações em Concessões (“the Company”) as at June 30, 2026, the consolidated statements of profit or loss, comprehensive income, changes in equity and cash flows for the six-month period then ended, and notes, comprising material accounting policies and other explanatory information (“the consolidated interim financial information”). Management is responsible for the preparation and fair presentation of this consolidated interim financial information in accordance with IFRS Accounting Standards as issued by the International Accounting Standards Board (IFRS Accounting Standards) including the requirements of IAS 34, “Interim Financial Reporting”. Our responsibility is to express a conclusion on this consolidated interim financial information based on our review.

Scope of Review

We conducted our review in accordance with the International Standard on Review Engagements 2410, “Review of Interim Financial Information Performed by the Independent Auditor of the Entity”. A review of interim financial information consists of making inquiries, primarily of persons responsible for financial and accounting matters, and applying analytical and other review procedures. A review is substantially less in scope than an audit conducted in accordance with International Standards on Auditing and consequently does not enable us to obtain assurance that we would become aware of all significant matters that might be identified in an audit. Accordingly, we do not express an audit opinion.

KPMG Auditores Independentes Ltda., uma sociedade simples brasileira, de responsabilidade limitada e firma-membro da organização global KPMG de firmas-membro independentes licenciadas da KPMG International Limited, uma empresa inglesa privada de responsabilidade limitada.

Conclusion

Based on our review, nothing has come to our attention that causes us to believe that the accompanying consolidated interim financial information do not give a true and fair view of the financial position of the Company as at June 30, 2026, and of its financial performance and its cash flows for the six-month period then ended in accordance with IFRS Accounting Standards including the requirements of IAS 34, “Interim Financial Reporting”.

Other information

The Company’s concessions consist of the operation of infrastructure projects through the collection of tariffs and revenues arising from the operation of the assets granted, as well as from the rental of areas and commercial spaces. The concessionaires are responsible for constructing, repairing, expanding, preserving, maintaining, and operating the infrastructure under concession, in accordance with the respective concession agreements. The Concession Grantors will transfer to the concessionaires the real estate and other assets in their possession upon execution of the concession agreements. The concessionaires are responsible for ensuring the integrity of the assets transferred to them, as well as for making new investments in the construction or improvement of the infrastructure.

The concession agreements establish annual adjustments to the basic tariffs in accordance with specific formulas set forth therein, which are generally based on inflation indices also specified in the agreements. Although the concession agreements do not include renewal clauses, the concession term may be extended in the event that the economic and financial rebalancing of the agreement executed between the parties is required.

The rights of the concession grantors to terminate the Group’s concession agreements include the unsatisfactory performance of the concessionaire and the material breach of the terms of such agreements.

The Group’s concession agreements may be terminated at the initiative of the concessionaire in the event of non-compliance with contractual standards by the concession grantor, such as the concession grantor’s failure to make payments as established in the agreement, by means of specific legal action filed for such purpose. In this case, the services provided by the Group’s concessionaires may not be interrupted or suspended until a final and unappealable judicial decision is rendered.

Execution of the Share Purchase and Sale Agreement

On November 18, 2025, Motiva Infraestrutura de Mobilidade S.A. (“Motiva” or “Motiva Group”), the ultimate parent company of CPC, entered into a share purchase with Aeropuerto de Cancún, S.A. de C.V., a subsidiary of the Grupo Aeroportuario del Sureste (“ASUR”), pursuant to which Motiva agreed to sell, and ASUR agreed to acquire, all of the shares of CPC.

On September 1, 2026, the transaction was completed following the satisfaction of all conditions precedent. As a result of the completion of this transaction, CPC became a direct subsidiary of Aeropuerto de Cancún, S.A. de C.V. and an indirect subsidiary of ASUR, and Motiva ceased to hold any ownership interest in CPC.

Reversible assets, option to renew concession agreements, and rights to terminate the agreement

All rights, privileges, and assets acquired, built, or transferred under the concession agreement are returned to the Concession Grantor at the end of the concession period, as a general rule, no indemnification is payable upon such reversion. However, a few highway concession agreements provide for the right to reimbursement relating to the investments necessary to ensure the continuity and adjustment of the services comprised by the concession agreement, provided that they were not depreciated/amortized and the implementation of which, duly authorized by the Concession Grantor, has taken place over the last five years of the concession period.

2. Presentation of the consolidated interim financial information

Statement of compliance

These consolidated interim financial information have been prepared in accordance with IFRS Accounting Standards as issued by the International Accounting Standards Board (“IFRS Accounting Standards”) including the requirements of IAS 34 - Interim Financial Reporting.

On September 21, 2026, the Company’s Management authorized the issuance of the consolidated interim financial information.

15

Companhia de Participações em Concessões

Notes to the consolidated interim financial information for the six-month period ended June 30, 2026

(Expressed in thousands of Mexican Pesos, unless otherwise indicated)

Measurement basis

The consolidated interim financial information have been prepared on a historical cost basis, except for financial instruments measured at fair value through profit or loss.

Functional and presentation currency

The functional currency of CPC is BRL (Brazilian Real). These consolidated interim financial information were presented in Mexican pesos (“MXN”). All balances have been rounded up to the nearest thousand, unless otherwise indicated.

Use of estimates and judgments

The preparation of the consolidated interim financial information requires Management to make judgments, estimates and assumptions that affect the application of accounting policies and the reported amounts for assets, liabilities, revenues and expenses. Actual profit or loss may differ from those estimates.

Estimates and assumptions are periodically reviewed by the Company’s Management, and the changes are recognized prospectively.

Uncertainties regarding assumptions and estimates

Information about uncertainties related to assumptions and estimates at the reporting date that have a significant risk of resulting in a material adjustment to the carrying amounts of assets and liabilities in the next year is included in the notes:

8.1. Expected credit loss: main assumptions for determining credit risk;

9.2. Recognition of deferred tax assets: availability of future taxable profit against which temporary deductible differences and tax losses can be used;

13. Amortization of intangible assets: amortization rate;

16. Provision for labor and social security risks: determination of sufficient value to cover probable estimated losses from ongoing lawsuits; and

20. Financial instruments measured at fair value: premises for measuring fair value, based on observable data.

3. Material accounting policies

The Group has consistently applied the following accounting policies to all periods presented in these consolidated financial statements.

3.1. Consolidation basis

Business combinations

Business combinations are accounted for using the acquisition method when the acquired set of activities and assets meets the definition of a business and control is transferred to the Group.

The Company measures goodwill as the excess of the fair value of the consideration transferred (including the recognized amount of any non-controlling interest in the acquiree) over the fair value of the identifiable assets acquired and liabilities assumed, all measured at the acquisition date. If the resulting amount is negative, a gain on a bargain purchase is recognized immediately in profit or loss.

In business combinations involving concession arrangements with defined contractual terms, any excess amount attributable to the future economic benefits arising from the concession is allocated to the concession intangible asset and amortized over the concession period, based on the pattern in which the related economic benefits are expected to be consumed.

Transaction costs, other than those associated with the issuance of debt or equity securities, incurred in a business combination are recognized as expenses as incurred.

If the initial accounting for a business combination is incomplete by the end of the reporting period in which the combination occurs, the provisional fair values recognized to date are presented. These provisional amounts are adjusted during the measurement period (one year), or additional assets or liabilities are recognized to reflect new information obtained about facts and circumstances that existed at the acquisition date and, if known, would have affected the amounts recognized at that date.

Subsidiaries and joint ventures

The Company controls an entity when it is exposed to variable returns or has the right over the variable returns that arise from its involvement with the entity, also having the capacity to affect those returns using its power over the entity. The financial information of the subsidiaries are included in the consolidated interim financial information from the time control is obtained until the date it no longer exists.

The financial information of subsidiaries is fully consolidated in the consolidated interim financial information.

The Company elected to initially measure any non-controlling interest at its proportionate share of the identifiable net assets of the acquiree at the acquisition date. Changes in the Company’s ownership interest in a subsidiary that do not result in a loss of control are accounted for as equity transactions.

17

Companhia de Participações em Concessões

Notes to the consolidated interim financial information for the six-month period ended June 30, 2026

(Expressed in thousands of Mexican Pesos, unless otherwise indicated)

When the entity loses control over a subsidiary, the Company derecognizes the assets and liabilities and any non-controlling interest and other components recorded in equity relating to that subsidiary. Any gain or loss from loss of control is recognized in the statement of profit or loss. If the Group retains any interest in the former subsidiary, that interest is measured at fair value at the date control is lost.

The financial information of joint ventures (ventures over which the Company exercises joint control, directly or indirectly, with one or more investor(s) through a contractual arrangement) are accounted for in the consolidated interim financial information using the equity accounting method.

Description of main consolidation procedures

The consolidated interim financial information include the financial information of the Company and its direct and indirect subsidiaries, as disclosed in Note 11.

The main consolidation procedures are as follows:

− Elimination of intercompany asset and liability account balances;

− Elimination of equity interests, reserves, and accumulated profits (losses) of the subsidiaries;

− Elimination of intercompany revenues and expenses and unrealized profits arising from transactions conducted by companies that are an integral part of the consolidation;

− Elimination of taxes on the portion of unrealized profits. Unrealized gains (losses) arising from transactions with investees, recognized under the equity accounting method, are eliminated against the investment in proportion to the parent company’s ownership interest in the investee; and

− The interests of non-controlling shareholders, in the shareholders’ equity and in the profit (loss) for the year in subsidiaries, are presented under the line item “Non-controlling interests (NCI)”.

3.2. Foreign currency

Transactions in foreign currency

Monetary assets and liabilities denominated in foreign currency are translated into the Company’s functional currency at the exchange rate prevailing at the end of the reporting period. Non-monetary assets and liabilities purchased or denominated in foreign currency are converted according to the exchange rates prevailing on the transaction dates or on the fair value measurement date, when this is used, and are included in the carrying amounts in Brazilian Reais of these transactions, not being subject to subsequent exchange-rate variation.

18

Companhia de Participações em Concessões

Notes to the consolidated interim financial information for the six-month period ended June 30, 2026

(Expressed in thousands of Mexican Pesos, unless otherwise indicated)

Gains and losses from exchange rate variations on the assets and liabilities are recognized in the statement of profit or loss.

Foreign operations

The assets and liabilities of foreign operations, including goodwill and fair value adjustments arising from the acquisition, are translated into Brazilian reais at the exchange rates prevailing at the reporting date. The revenue and expenses of foreign operations are translated into Brazilian reais at the monthly average exchange rate.

Foreign currency translation differences are recognized in Other Comprehensive Income and accumulated under the caption Currency translation adjustments in equity. If the subsidiary is not wholly owned, the corresponding portion of the translation difference is attributed to non-controlling interests.

Translation of financial statements from the functional currency to the presentation currency

The financial information of each entity included in the consolidation of CPC’s consolidated financial statements are prepared using the functional currency of the primary economic environment in which it operates. At the entity level, transactions in foreign currencies other than the functional currency of the entity are initially measured using the exchange rates prevailing at the dates of each transaction. Foreign currency monetary items in the statement of financial position are translated using the closing exchange rate as of the reporting date. Foreign exchange gains and losses resulting from the settlement of such transactions and from the remeasurement at period end of foreign currency monetary assets and liabilities are recognized in the consolidated statement of income, under the captions “Finance income” or “Finance expense.” For consolidation purposes, the financial statements of subsidiaries whose functional currency is different from the CPC’s presentation currency are translated into MXN. Assets and liabilities are translated at the exchange rates prevailing at the reporting date, while income and expenses are translated at average exchange rates for the period. Exchange differences arising from the translation of the financial statements of subsidiaries whose functional currency differs from the Group’s presentation currency are recognized in other comprehensive income and accumulated in equity as a cumulative translation adjustment.

3.3. Revenue from agreements with customers

A five-step model for accounting of revenue arising from agreements with customers is applied, so that revenue is recognized at an amount that reflects the consideration to which the entity expects to receive in exchange for the transfer of the assets or services control to a customer.

The five steps mentioned above are: (1) identification of agreements with customers; (2) identification of the performance obligations; (3) determination of transaction price; (4) allocation of transaction price for performance obligations; and (5) revenue recognition.

Airport revenue is recognized when airport services are used by customers.

Ancillary revenue is recognized when the related services are rendered. Revenue from operating leases is recognized on a straight-line basis over the lease term.

Construction revenue: under IFRIC 12, when the concessionaire provides infrastructure construction or improvement services, revenues and costs related to these services are calculated, which are determined according to the stage of completion of the physical progress of the contracted assignment, which is aligned with the measurement of assignments performed.

Tariff values are agreed upon at the conclusion of each concession agreement, which provide for annual readjustments.

The Company also earns revenue from the provision of administrative services to other non-controlled companies within the Group and recognizes such revenue as the services are rendered.

Revenues are not recorded if there is significant uncertainty as to their realization.

See note 18 for further details.

3.4. Financial instruments

Initial recognition and measurement

Accounts receivable and debt securities are initially recognized on the date they originated. All other financial assets and liabilities are initially recognized when the Group becomes one of the parties to the contractual provisions of the instrument.

20

Companhia de Participações em Concessões

Notes to the consolidated interim financial information for the six-month period ended June 30, 2026

(Expressed in thousands of Mexican Pesos, unless otherwise indicated)

A financial asset (unless in the case of trade receivables from customers without a significant financing component) or a financial liability is initially measured at fair value, plus or minus, for an item not measured at fair value through profit or loss (FVTPL), the transaction costs that are directly attributable to its acquisition or issuance. Trade receivables without a significant financing component are initially measured at the transaction price.

Subsequent classification and measurement

Financial assets

In initial recognition, a financial asset is classified as measured: at amortized cost or to FVTPL.

Financial assets are not subsequently reclassified after their initial recognition unless the Group changes its business model for managing financial assets, in which case all affected financial assets are reclassified on the first day of the reporting period following the change in the business model.

A financial asset is measured at amortized cost if it meets both of the following conditions and is not designated as measured at FVTPL:

· it is maintained within a business model whose objective is to hold financial assets in order to collect contractual cash flows; and

· its contractual terms generate, on specific dates, cash flows related only to payment of principal and interest on the outstanding principal amount.

All financial assets not classified as measured at amortized cost, as described above, are classified as FVTPL. This includes all derivative financial assets. At initial recognition, the Group may irrevocably designate a financial asset that would otherwise meet the requirements to be measured at amortized cost as at FVTPL if doing so eliminates or significantly reduces an accounting mismatch that would otherwise arise.

Financial assets - Assessment of the business model

The Group assesses the objective of the business model in which a financial asset is held in a portfolio because this best reflects how the business is managed and how information is provided to Management. The information considered includes:

21

Companhia de Participações em Concessões

Notes to the consolidated interim financial information for the six-month period ended June 30, 2026

(Expressed in thousands of Mexican Pesos, unless otherwise indicated)

· the policies and goals established for the portfolio and the practical functioning of such policies. They include whether Management’s strategy focuses on obtaining contractual interest revenue, maintaining a certain interest rate profile, matching the duration of financial assets with the duration of related liabilities or expected cash outflows, or the realization of cash flows through the sale of assets;

· how the portfolio’s performance is evaluated and reported to the Group’s Management;

· the risks that affect the performance of the business model (and the financial asset held in that business model) and the way those risks are managed;

· how business managers are remunerated, for example, whether the remuneration is based on the fair value of the assets managed or on the contractual cash flows obtained; and

· the frequency, volume, and timing of sales of financial assets in prior periods, the reasons for such sales, and expectations for future sales.

Transfers of financial assets to third parties in transactions that do not qualify for derecognition are not considered sales, consistent with the Group’s continuing recognition of the assets.

Financial assets held for trading or managed with performance measured at fair value are measured at fair value through profit or loss.

Financial assets – Assessment of whether contractual cash flows are only payments of principal and interest

For the purposes of such assessment, “principal” is defined as the fair value of a financial asset upon initial recognition. “Interest” is defined as a consideration for the value of money over time for the credit risk associated with the outstanding principal over a given period and for the other basic risks and costs of loans (for example, liquidity risk and administrative costs), as well as a profit margin.

The Group considers the contractual terms of the instrument to assess whether the cash flows are solely payments of principal and interest. This includes assessing whether the financial asset contains a contractual term that could change the timing or value of contractual cash flows so that it would not meet this condition. In making this assessment, the Group considers:

· contingent events that change the value or timing of cash flows;

· terms that may adjust the contractual rate, including variable rates;

· prepayment and extension of the term; and

· terms that limit the Group’s access to cash flows from specific assets (for example, based on the performance of an asset).

22

Companhia de Participações em Concessões

Notes to the consolidated interim financial information for the six-month period ended June 30, 2026

(Expressed in thousands of Mexican Pesos, unless otherwise indicated)

Prepayment is consistent with the payment criterion of principal and interest if the prepayment amount represents, in the most part, unpaid amounts of principal and interest on the outstanding amount of principal—which may include reasonable compensation for the early termination of the contract. Furthermore, in relation to a financial asset acquired at a value lower or greater than the nominal value of the agreement, the authorization or requirement of prepayment at a value representing the nominal value of the agreement plus contractual interest accrued (but unpaid) (which may also include reasonable offsetting for the early termination of the contract) are treated as consistent with this criterion if the fair value of the prepayment is insignificant at the initial recognition.

Financial assets – Subsequent measurement and gains and losses

Financial assets at amortized cost	These assets are subsequently measured at amortized cost using the effective interest method. The amortized cost is reduced by impairment losses. The revenue from interest, exchange gains and losses, and impairment are recognized in the statement of profit or loss. Any gain or loss on derecognition is recognized in the statement of profit or loss.
Financial assets at FVTPL	These assets are subsequently measured at fair value. Net profit or loss, including interest, is recognized in the statement of profit or loss.

Derecognition

Financial assets

The Group derecognizes a financial asset when:

· the contractual rights to the cash flows from the asset expire; or

· it transfers the contractual rights to receive the contractual cash flows on a financial asset in a transaction where:

· all the risks and benefits of ownership of the financial asset are substantially transferred; or

· the Group neither transfers nor retains substantially all the risks and rewards of ownership of the financial asset and does not retain control over the financial asset.

23

Companhia de Participações em Concessões

Notes to the consolidated interim financial information for the six-month period ended June 30, 2026

(Expressed in thousands of Mexican Pesos, unless otherwise indicated)

The Group enters into transactions in which it transfers assets recognized in the balance sheet but retains all or substantially all of the risks and rewards of the transferred assets. In such cases, financial assets are not derecognized.

Financial liabilities

The Group derecognizes a financial liability when its contractual obligations are discharged, cancelled, or expire. The Group also derecognizes a financial liability when its terms are modified and the cash flows of the modified liability are substantially different, in which case a new financial liability based on the modified terms is recognized at fair value.

Upon the derecognition of a financial liability, the difference between the terminated carrying amount and the consideration paid (including transferred assets that do not transit through the cash or liabilities assumed) is recognized in the statement of profit or loss.

Hedge accounting

The Company designates certain hedging instruments related to foreign currency and interest rate risk as fair value hedges or cash flow hedges.

At the beginning of the hedging relationship, the Company documents the relationship between the hedging instrument and the hedged item, along with its risk management objectives and its strategy for undertaking various hedging transactions. Additionally, at the inception of the hedge and on an ongoing basis, the Company documents whether the hedging instrument used in a hedging relationship is highly effective in offsetting changes in the fair value or cash flow of the hedged item attributable to the hedged risk.

Note no. 20 provides further details on the fair value of derivative instruments used for hedging purposes.

Cash flow hedge: hedge of the exposure to variability in cash flows that is attributable to a particular risk associated with a recognized asset or liability (such as all or some of the future interest payments on a variable-rate debt) or a highly probable anticipated transaction that could affect profit or loss.

The effective portion of changes in the fair value of derivatives that is designated and qualified as a cash flow hedge is recognized in other comprehensive income and accumulated in the cash flow hedge item, in equity, and is limited to the cumulative change in the fair value of the hedged item, determined on a present value basis, since the inception of the hedge. Losses or gains related to the ineffective portion are recognized immediately in the profit or loss for the period.

Amounts previously recognized in other comprehensive income and accumulated in equity are reclassified to profit or loss in the period in which the hedged item is recognized in profit or loss, under the same heading in the income statement in which such item is recognized.

24

Companhia de Participações em Concessões

Notes to the consolidated interim financial information for the six-month period ended June 30, 2026

(Expressed in thousands of Mexican Pesos, unless otherwise indicated)

Hedge accounting is discontinued when the Company cancels the hedging relationship, the hedging instrument expires or is sold, terminated, or enforced, or when it no longer qualifies as hedge accounting.

When the hedged transaction is no longer expected to occur, the accumulated and deferred gains or losses in equity are recognized immediately in profit or loss.

Offsetting

Financial assets and liabilities are offset and the net amount is presented in the balance sheet when, and only when, the Group currently has a legally enforceable right to offset the amounts and intends either to settle them on a net basis or to realize the asset and settle the liability simultaneously.

3.5. Cash and cash equivalents and financial investments

Cash and cash equivalents

Cash and cash equivalents encompass the balances of cash and immediately convertible financial investments with insignificant risk of change in value. These funds are kept for the purpose of meeting short-term commitments.

In addition to the criteria above, the projected resource outflows for the next 3 months from the date of the evaluation are used as a classification parameter.

Financial investments

Financial investments comprise financial assets whose expected realization exceeds three months from the acquisition date, or that are not readily available for general use, and therefore do not qualify for classification as cash and cash equivalents.

3.6. Transaction cost in the issuance of debt securities

Costs incurred to raise funds from third parties are initially deducted from the carrying amount of the related financial liability and subsequently recognized in profit or loss as the term elapses, based on the amortized cost method, which considers the Effective Interest Rate (EIR) of the transaction to appropriate financial charges during the term of the transaction. The internal return rate takes into account all cash flows, from the net present value of the transaction through all payments made or to be made, for the settlement of the transaction.

25

Companhia de Participações em Concessões

Notes to the consolidated interim financial information for the six-month period ended June 30, 2026

(Expressed in thousands of Mexican Pesos, unless otherwise indicated)

3.7. Property, plant, and equipment

Recognition and measurement

Property, plant, and equipment are measured at the historical cost, including acquisition and construction costs, less accumulated depreciation and any accumulated impairment losses, when necessary.

The costs of property, plant, and equipment are composed of expenditures that are directly attributable to the acquisition/construction of the assets, including the costs of materials, direct labor, and any other costs to place the asset in the location and condition necessary for it to operate. Additionally, for qualified assets, loan costs are capitalized.

When parts of an item of property, plant, and equipment have different useful lives, they are accounted for as individual items (major components) of property, plant, and equipment.

Other expenditures are capitalized only when there is an increase in the future economic benefits of the item of property, plant, and equipment to which it refers; if not, it is recognized in the statement of profit or loss as expenses.

Gains and losses on disposal of an item of property, plant, and equipment determined by comparing the proceeds from disposal with the carrying amount of the same are recognized in the statement of profit or loss as other operating revenues/expenses.

The replacement cost of a property, plant, and equipment component is recognized as such when it is probable that future economic benefits are embodied in it and its cost can be reliably measured. The carrying amount of a component replaced by another is written off. The maintenance costs are recognized in the statement of profit or loss when incurred.

Depreciation

Depreciation is calculated using the straight-line basis, at the rates compatible with the economic useful life and/or concession period, whichever is shorter. The useful lives are shown in note 12.

The depreciation methods, useful lives, and residual values are reviewed at the end of each year and potential adjustments are recognized as changes in accounting estimates.

Notes to the consolidated interim financial information for the six-month period ended June 30, 2026

(Expressed in thousands of Mexican Pesos, unless otherwise indicated)

3.8. Intangible assets

The Company has the following intangible assets:

· Software licenses and development costs

These assets are measured at cost less accumulated amortization and accumulated impairment losses, if any. Amortization is recognized on a straight-line basis over their estimated useful lives.

· Infrastructure exploration rights – see Note 3.14.

Assets under construction are classified as Construction in Progress.

3.9. Impairment of assets

Non-derivative financial assets

The Group recognizes allowances for expected credit losses on financial assets measured at amortized cost.

Expected credit losses with a significant financing component are measured over 12 months, unless credit risk has increased significantly, in which case losses allowances are measured over the entire life of the asset.

Expected credit losses for 12 months are credit losses that result from potential default events within 12 months after the reporting date (or in a shorter period if the expected life of the instrument is less than 12 months).

Provisions for losses regarding trade receivables without a significant component of financing are measured at a value equal to a credit loss estimated for the instrument’s entire life, which derives from all possible default events throughout the financial instrument’s expected life.

The maximum period considered in estimating expected credit losses is the maximum contractual period over which the Group is exposed to credit risk.

In determining whether the credit risk of a financial asset has increased significantly since initial recognition and in estimating expected credit losses, the Group considers reasonable and supportable information that is relevant and available without undue cost or effort. This includes quantitative and qualitative analyses based on the Group’s historical experience, credit assessment, and consideration of forward-looking information (forward-looking).

27

Companhia de Participações em Concessões

Notes to the consolidated interim financial information for the six-month period ended June 30, 2026

(Expressed in thousands of Mexican Pesos, unless otherwise indicated)

Expected credit losses are estimates weighted by the probability of credit losses. When applicable, credit losses are measured at present value, based on the difference between the cash flows due to the Group in accordance with the agreement and the cash flows the Group expects to receive. The expected credit losses are discounted by the effective interest rate of the financial asset.

The gross carrying amount of a financial asset is written off when the Group has no reasonable expectation of recovering the financial asset in full or in part. However, financial assets written off may still be subject to collection activities to comply with the Group’s procedures for recovering amounts due.

The loss allowance for financial assets measured at amortized cost is deducted from the gross carrying amount of the assets and charged to profit or loss.

Non-financial assets

The carrying amounts of non-financial assets are reviewed annually to determine if there is an indication of impairment loss. For impairment testing purposes, assets are grouped into cash-generating units (CGUs), and, if any such indication exists, the recoverable amount of the respective CGU is estimated.

The Group determines an asset’s value in use based on the present value of expected cash flow projections, based on budgets approved by Management, as of the valuation date and through the end of the concession term, considering discount rates that reflect the specific risks associated with each cash-generating unit.

During the projection period, the key assumptions considered are related to estimates of traffic for the infrastructure projects held, indices used to adjust tariffs, growth in Gross Domestic Product (GDP) and the respective GDP elasticity of each business, operating costs, inflation, capital expenditures, discount rates, and contractual rebalancing.

An impairment loss is recognized in the statement of profit or loss when the carrying amount of an asset exceeds its estimated recoverable amount.

The recoverable value of an asset is the higher between its value in use and its fair value, less costs of disposal. The value in use is based on estimated future cash flows discounted to present value using a discount rate before taxes that reflects current market evaluations of the value of money over time and the specific risks of the asset.

28

Companhia de Participações em Concessões

Notes to the consolidated interim financial information for the six-month period ended June 30, 2026

(Expressed in thousands of Mexican Pesos, unless otherwise indicated)

At the end of each reporting period, the Group assesses whether there is any indication that previously recognized impairment losses may no longer exist or may have decreased. An impairment is reversed in case of changes in the estimates used to determine the recoverable value, only to the extent that the asset’s carrying amount does not exceed the carrying amount that would have been determined, less depreciation or amortization, had no impairment been recognized.

3.10. Provisions

A provision is recognized in the balance sheet when the Company has a legal or unformalized obligation incorporated as a result of a past event, which can be reliably estimated, and it is probable that economic resources will be required to settle the obligation. Provisions are calculated by discounting the expected future cash flows at a pre-tax rate which reflects the current market evaluations as to the value of the cash over time and the specific risks of the liability. The financial costs incurred are recorded in the statement of profit or loss.

3.11. Financial revenues and expenses

Financial revenue basically comprises interest from financial investments, changes in the fair value of financial assets, which are recorded through the profit or loss for the year, and positive adjustments for inflation and exchange rate variations on financial instruments, whether classified as assets or liabilities..

Financial expenses basically comprise interest, inflation adjustments and exchange-rate variations on financial liabilities, rearrangement of adjustments to present value on provisions, and changes in the fair value of financial assets measured at fair value through profit or loss. Loan costs that are not directly attributable to the acquisition, construction, or production of qualifying assets are recognized in the statement of profit or loss for the year using the effective interest method.

3.12. Employee benefits

Defined contribution plans

A defined contribution plan is a post-employment benefit plan under which an entity pays fixed contributions to a separate entity (pension fund) and will have no obligation to pay further amounts. Obligations for contributions to defined contribution pension plans are recognized as employee benefit expenses in the statement of profit or loss, for the periods in which the services are rendered by the employees.

(Expressed in thousands of Mexican Pesos, unless otherwise indicated)

Short-Term Employee Benefits

Short-term employee benefit obligations are measured on an undiscounted basis and are recorded as expenses as the related service is provided.

3.13. Income tax and social security contributions

Current and deferred income tax and social contribution are calculated based on the tax rates of 15% plus a surcharge of 10% on taxable profit in excess of BRL 240 (annual basis – equivalent to MXN 814) for income tax and 9% on taxable profit for social security contribution on net income, considering the offsetting of tax losses and negative basis of social security contribution limited to 30% of the taxable profit.

Current and deferred taxes are recognized in the statement of profit or loss unless they are related to items recognized directly in equity.

Current taxes are the taxes payable on the taxable profit for the year, at rates effective on the date of consolidated interim financial information.

Deferred taxes are recognized in relation to temporary differences between the carrying amounts of the assets and liabilities for accounting purposes, and the corresponding amounts are used for taxation purposes. Deferred tax assets and liabilities are measured based on tax rates that are expected to be applied to the temporary differences when they are reversed, based on tax rates that were decreed up to the reporting date, which reflect the uncertainty related to tax on profit, if any.

To determine current and deferred income tax, the Company takes into consideration the impact of uncertainties on positions taken on taxes and if the additional income tax and interest payment should be made. The Company believes that the provision for income tax recorded in liabilities is adequate for all outstanding years, based on its evaluation of several factors, including interpretations of tax laws and past experience. This evaluation is based on estimates and assumptions that may involve a range of judgments on future events. New information may be provided, making the Company change its judgment on the adequacy of the existing provision; such changes will impact income tax expenses for the year in which they are made. Deferred tax assets and liabilities are offset when there is a legally enforceable right to compensate current tax assets and liabilities, and the latter relate to income taxes levied by the same tax authority on the same taxable entity subject to taxation.

A deferred income tax and social security contribution asset is recognized for tax losses, negative bases, and deductible temporary differences, to the extent that it is probable that future taxable profit will be available against which these can be used, such use being limited to 30% of future annual taxable profit.

Companhia de Participações em Concessões

Notes to the consolidated interim financial information for the six-month period ended June 30, 2026

(Expressed in thousands of Mexican Pesos, unless otherwise indicated)

Deferred tax assets arising from temporary differences consider the expected generation of future taxable profit, based on a technical feasibility study approved by management, which includes assumptions that are affected by expected future conditions of the economy and the market, in addition to assumptions of growth in the revenue arising from each operating activity of the Company, which may be impacted by economic reductions or growth, expected inflation rates, traffic volume, among others.

Deferred tax is not recognized for:

· temporary differences on the initial recognition of assets and liabilities in a transaction that is not a business combination, and which does not affect the taxable profit or loss, nor the accounting result; and

· temporary taxable differences arising from the initial recognition of goodwill.

3.14. Service concession agreements – Infrastructure operation right (IFRIC 12)

The infrastructure, within the scope of Technical Interpretation IFRIC 12 - Concession Agreements, is not recognized as the concessionaire’s property, plant, and equipment, since the concession agreement sets forth only the transfer of ownership of these assets for the provision of public services, and they are handed over to the Concession Grantor after the termination of the relevant agreement. The concessionaire has access to construct and/or operate the infrastructure for the provision of services for a specified period under the concession agreement.

Under the terms of the concession agreements in the scope of IFRIC 12, the concessionaire is a service renderer, building or improving the infrastructure (construction or improvement services) used to provide a public service and operates and maintains this infrastructure (operation services) during a determined period.

If the concessionaire provides construction or improvement services, received or receivable remuneration is recorded at fair value. This remuneration may correspond to a right over an intangible asset, financial asset, or both. The Concessionaire recognizes an intangible asset to the extent it receives the right (authorization) to charge the users for the provision of public services. The Concessionaire recognizes a financial asset to the extent that it has the unconditional contractual right to receive cash or another financial asset from the Concession Grantor for the construction services.

Such financial assets are measured at their fair value on initial recognition and then measured at amortized cost.

31

Companhia de Participações em Concessões

Notes to the consolidated interim financial information for the six-month period ended June 30, 2026

(Expressed in thousands of Mexican Pesos, unless otherwise indicated)

Should the Company be partially remunerated for the construction services through a financial asset and partially through an intangible asset, each item of the remuneration received or receivable is individually registered, and it is initially recognized at the fair value of the remuneration received or receivable.

The infrastructure operation right results from expenses on construction works for improvements in exchange for the right to charge users for the use of the infrastructure. This right is comprised of construction cost plus profit margin and loan costs attributable to this asset. The Company estimated that any margin, net of taxes, is immaterial, considering it as zero.

The infrastructure exploration right may also arise from payments to the Granting Authority in exchange for the right to charge users for the use of the infrastructure, such as the existing concessions at BH Airport, Bloco Sul, Bloco Central and Pampulha.

Expenditures incurred in the performance of improvement construction works that do not generate future economic benefits are recorded as costs when incurred, as they do not meet the criteria for recognition of intangible assets.

Because concession agreements are subject to execution, construction of infrastructure improvement works are only recognized in the accounting records when they are physically executed.

Additionally, the Company accountably recognizes the non-monetary assets from the concession agreements entered into with the Concession Grantors related to the extension of terms resulting from economic rebalancing, according to the characteristics mentioned above, as intangible assets at its fair value, since there is no associated performance obligation, as intangible assets, the corresponding entry being revenue in the profit or loss. Regarding the amount registered in the profit or loss, deferred tax liabilities are constituted, originating from the temporary difference.

Amortization of the infrastructure exploration right is recognized in profit or loss based on the expected economic benefit curve over the concession term, taking into consideration the estimated curve of airport passenger traffic as the basis for amortization.

3.15. Segment information

Segment information is presented in accordance with IFRS 8 – Segment Information.

The Company’s Management in place at the reporting date, appointed by the Motiva Group and acting as the Chief Operating Decision Maker (“CODM”), regularly reviewed the Company’s operational and financial information for purposes of performance assessment and resource allocation.

32

Companhia de Participações em Concessões

Notes to the consolidated interim financial information for the six-month period ended June 30, 2026

(Expressed in thousands of Mexican Pesos, unless otherwise indicated)

Based on the information reviewed by the CODM as of the reporting date, the Company operated in a single operating segment, consisting of airport concession activities. Therefore, segment information is presented on a consolidated basis.

3.16. New standards not yet in effect

Certain new standards will become effective for periods ending after January 01, 2026, and have not been adopted in the preparation of these consolidated interim financial information.

Presentation and disclosure of financial statements

IFRS 18 will replace IAS 1 – Presentation of Financial Statements and applies to annual reporting periods beginning on or after January 1, 2027. The new standard introduces the following key new requirements:

· Entities are required to classify all income and expenses into five categories in the statement of profit or loss: operating, investing, financing, discontinued operations, and income tax. Entities are also required to present a newly defined operating profit subtotal. Entities’ net profit will not change.

· Management-defined performance measures (MPMs) are disclosed in a single note to the financial statements.

· Enhanced guidance is provided on how to group information in the financial statements.

Additionally, all entities are required to use the operating profit subtotal as the starting point for the statement of cash flows when presenting operating cash flows using the indirect method.

The Group is still in the process of assessing the impact of the new standard, particularly with respect to the structure of the Group’s statement of profit or loss, statement of cash flows, and additional disclosures required for MPMs. Entities are required to classify all revenues and expenses into five categories in the Statement of Profit or Loss, namely: operating, investing, financing, discontinued operations, and income tax.

Other accounting standards

The following amended standards are not expected to have a significant impact on the consolidated interim financial information:

· Nature-related electricity agreements (amendments to IFRS 7 and IFRS 9); and

· Classification and Measurement of Financial Instruments (amendments to IFRS 7 and IFRS 9).

(Expressed in thousands of Mexican Pesos, unless otherwise indicated)

3.18. Tax reform

On December 20, 2023, Constitutional Amendment No. 132 was enacted, establishing the Consumption Tax Reform based on the Dual VAT model: the Contribution on Goods and Services (CBS - Federal) and the Tax on Goods and Services (IBS - Subnational).

On January 16, 2025, Complementary Law No. 214/2025 (originating from PLP 68/2024) was enacted, regulating the main provisions of the new regime and the Excise Tax (IS).

On April 30, 2026, Decree No. 12,955/2026 was published, regulating the CBS, providing, among other aspects, for the incidence, calculation basis, and passive subjection, as well as the operational rules applicable to the federal tax.

The transition to the new system will take place between 2026 and 2032. Given the current transition phase and the dependence on regulatory definitions, the quantitative effects of the Reform on the calculation of taxes cannot yet be estimated with precision. Consequently, there were no measurable impacts on these consolidated interim financial information as of June 30, 2026.

Management notes that the concession agreements operated by the Group provide for economic and financial rebalancing arising from impacts on revenue. Therefore, any increases in tax costs resulting from the transition shall be subject to economic and financial rebalancing.

3.19 Share-based payment

Share-based payments, payable in shares, are accounted for at the fair value of the equity instruments granted at the grant date. This cost is recognized over the vesting period of the instruments.

4. Determination of fair values

A number of the Company’s accounting policies and disclosures require the determination of fair value, for both financial and non-financial assets and liabilities. Fair values have been determined for measurement and/or disclosure purposes, based on the following methods. When applicable, additional information about the assumptions made in determining fair values is disclosed in the notes specific to that asset or liability.

34

Companhia de Participações em Concessões

Notes to the consolidated interim financial information for the six-month period ended June 30, 2026

(Expressed in thousands of Mexican Pesos, unless otherwise indicated)

· Cash and banks

The fair values of these financial assets are equal to the carrying amounts, considering their immediate liquidity.

· Financial investments

The fair value of financial assets measured at fair value through profit or loss is determined by reference to their closing prices on the date of recognition of consolidated interim financial information.

· Non-derivative financial liabilities

The fair value determined for accounting and/or disclosure purposes is calculated based on the present value of projected future cash flows. The rates used in calculations were obtained from public sources (B3 and Bloomberg).

The Company uses observable market data as much as possible to measure the fair value of an asset or a liability. Fair values are classified at different levels in a hierarchy based on inputs used in valuation techniques in the following way. The different levels are defined below:

	·	Level 1: (non-adjusted) prices traded in active markets for identical assets and liabilities;
	·	Level 2: inputs, other than prices traded in active markets included in tier 1, that are observable for the asset or liability, either directly (prices) or indirectly (derived from prices); and
	·	Level 3: assumptions, for assets or liabilities, which are not based on observable market data (non-observable inputs).

5. Financial risk management

5.1 Overview

The Company is exposed to the following risks:

a) Credit risk;

b) Interest rates and inflation risk;

c) Foreign exchange rate risk; and

d) Financial risk and liquidity.

35

Companhia de Participações em Concessões

Notes to the consolidated interim financial information for the six-month period ended June 30, 2026

(Expressed in thousands of Mexican Pesos, unless otherwise indicated)

Information on the Company’s exposure to each of the abovementioned risks, the goals, policies, and processes for measuring and managing risk and capital is presented below. Additional quantitative disclosures are included throughout these consolidated interim financial information.

a. Credit risk

Credit risk arises from the possibility that the Company and its subsidiaries may incur losses resulting from default by counterparties or financial institutions that hold cash and cash equivalents or financial investments. To mitigate these risks, the Group adopts as a practice the analysis of the financial and equity position of its counterparties, as well as the establishment of credit limits and ongoing monitoring of outstanding positions, except for accounts receivable from Concession Grantors, which are primarily subject to concession risk. As regards financial institutions, operations are only carried out with low-risk financial institutions, assessed by rating agencies. Further details in this regard can be found in Notes 7, 8, 10, 14, 15, and 20.

b. Interest rates and inflation risk

Arises from the possibility of reduced gains or increased losses arising from oscillations in interest rates on its financial assets and liabilities.

The Company and its subsidiaries are exposed to floating interest rates, primarily related to variations in: (1) the Long-Term Interest Rate (TJLP) and the Interbank Deposit Certificate (CDI) applicable to borrowings in Brazilian reais; (2) the General Market Price Index (IGP-M), the Broad Consumer Price Index (IPCA), and the CDI applicable to debentures; and (3) the IGP-M and IPCA applicable to the concession term. The interest rates of financial investments are mainly linked to the CDI rate variation. Further details in this regard can be found in Notes 7, 10, 14, 15, and 20.

The Group’s concession tariffs are adjusted based on inflation indices.

c. Exchange rate risk

This risk arises from the possibility of fluctuations in the exchange rates of foreign currencies used for the acquisition of equipment and supplies abroad, as well as for the settlement of financial liabilities. In addition to amounts payable and receivable in foreign currencies, the Company has investments in subsidiaries and joint ventures abroad and has cash flows from purchases and sales in other currencies. The Company, its subsidiaries, and joint ventures continually assess whether to enter into hedging transactions to mitigate these risks.

36

Companhia de Participações em Concessões

Notes to the consolidated interim financial information for the six-month period ended June 30, 2026

(Expressed in thousands of Mexican Pesos, unless otherwise indicated)

The subsidiaries finance part of their operations through loans and financing denominated in foreign currencies linked to the U.S. dollar (USD) equivalent, as of June 30, 2026.

For further details, see Notes 14 and 20.

d. Financial risk and liquidity

This risk arises from the choice between equity financing (capital contributions and retained earnings) and third-party capital used by the Company and its subsidiaries to finance their operations. Liquidity risk is the risk that the Group will encounter difficulties in meeting obligations associated with financial liabilities that are settled through cash payments or the delivery of another financial asset. To mitigate liquidity risks and optimize the weighted average cost of capital, the Group monitors investment and indebtedness levels in accordance with market standards and compliance with covenants set forth in loan, financing, and debenture agreements. Management believes that the Company and its subsidiaries have the capacity to maintain business continuity under normal operating conditions.

Information on the maturity of financial instruments liabilities may be obtained in the respective note.

The table below shows non-derivative financial liabilities according to maturity intervals, corresponding to the period remaining in the balance sheet until the contractual maturity date. These are gross, non-deducted amounts and include payment of contractual interest:

(b) Provisions: For labor, tax, civil and contractual risks, equity-accounted investments (PLR), and losses allowances – accounts receivable.

CPC and its subsidiary SPAC did not recognize deferred tax assets on tax loss carryforwards and negative tax bases amounting to MXN 769,056 and MXN 899,605, respectively, as there is no expectation of generating taxable profit in the long term. If recognized, the deferred tax asset balance (IRPJ/CSLL) would amount to MXN 273,229 as of June 30, 2026 (MXN 267,082 as of December 31, 2025).

11.4 Other relevant information – Legal, administrative-regulatory, and arbitration proceedings related to concession agreements issues

The Company and its subsidiaries are parties to legal, administrative-regulatory, and arbitration proceedings related to concession agreements matters.

In the context of concessions in general, administrative-regulatory proceedings are the formal instruments through which interaction between concessionaires and Concession Grantors occurs (such as a service provider relationship with the customer) regarding various topics relating to the concession agreements, covering, but not limited to, matters that affect the contractual interpretation and the economic-financial balance of the concession. Such administrative-regulatory proceedings can be initiated by either party, and technical, regulatory, contractual, and legal topics of different natures regarding the dynamics of the concession are presented and discussed. During their course, such proceedings bring preliminary or non-definitive positions regarding the legal expectations of each requesting party. Administrative decisions must be made in compliance with the governing legislation and the concession agreements themselves and, in general, may be subject to judicial or arbitration review.

The nature of these contractual discussions typically involves tariff adjustments, force majeure events (i.e., COVID-19 pandemic), changes to the time of execution or scope of the construction works provided for in the concession agreements, controversies regarding compliance or non-compliance with specific contractual requirements, or even the form of measurement.

There are uncertainties related to the measurement of regulatory proceedings, including: (i) the understanding of each party on the topic, (ii) negotiations or their subsequent developments, which substantially alter the amounts involved, (iii) the complexity of measurement, which commonly involves technical expertise, (iv) the high probability of different issues being evaluated and resolved jointly, based on the respective net balance of the recognized claims of each party, and (v) the form of settlement.

Final resolutions on regulatory issues can occur in different, non-exclusive ways, such as: (i) receipt or payment in cash, (ii) extension or reduction of the concession agreement term, and (iii) reduction or increase of commitment to future investments, increase or reduction of the tariff.

Furthermore, rebalancing received in the form of a tariff increase or reduction is recognized as the service is provided by the concessionaire, as well as rebalancing in the form of a reduction or increase in future investment commitments, which, being executory agreements, will be recognized with the realization of the infrastructure improvement construction work. Management reiterates its confidence in the current legal procedures applicable to concession agreements and assesses the risk of loss of discussions related to regulatory matters of the agreements as being remote and/or with no expectation of cash disbursement.

17.4. Long-Term Incentive Plans, payable in shares

No new Long-Term Incentive Plans were granted during the semester. The plans granted in prior years retain the characteristics disclosed in the notes to the respective consolidated interim financial information, with 185,580 shares remaining to vest as the vesting period progresses.

Settlement of share-based payment awards

In connection with the sale transaction of CPC, concluded on September 1, 2026 (see note n. 1), the following settlement conditions apply to the outstanding long-term incentive plans:

· Lock-up: The one-year lock-up restriction is released upon closing of the transaction.

· Retention Tranche (50% of each grant): Motiva’s shares will be transferred to the beneficiaries at closing, with immediate settlement, regardless of the originally established vesting schedule.

· Performance Tranche (50% of each grant): Settlement remains subject to the measurement and achievement of the applicable TSR index. The vesting periods are accelerated and deemed fulfilled as of the closing date; however, the actual transfer of shares is contingent upon confirmation that the TSR (Total Shareholder Return) target has been met, and this tranche remains restricted until the index is determined.

· Share transfer (2023, 2024 and 2025 grants): Settled through the transfer of shares at closing, under the conditions described above.

The lock-up release process has been initiated, with the share transfer expected to take place in October 2026.

17.5. Profit retention reserve

On April 30, 2026, at the Annual General Meeting, the retention of MXN 360,672 in the Retained Earnings Reserve was approved, as previously disclosed as an additional dividend as of December 31, 2025.

(a) Economic and financial rebalancing revenue for Aeris, resulting from the execution of the 4th Amendment to the Airport Concession Agreement for the operation of Aeroporto Juan Santamaría.

18.1 Seasonality of operations

The airport segment is subject to seasonality at airports located both abroad and in Brazil, with peak demand from leisure travelers occurring in December, January and July, driven by school holidays and Northern Hemisphere vacation periods, as well as extended public holidays such as Christmas, New Year, Carnival (in Brazil), and Holy Week. Additional demand peaks arise from traditional local festivals in the states and/or municipalities where the airports are located, including the Festa de São João in São Luís and Petrolina, and the Oktoberfest in Blumenau.

Although business travel demand tends to decline during these same periods, the increase in leisure travel demand generally more than offsets such reduction, which generally contributes positively to the Group’s operating performance during these periods.

For the 12 months ended June 30, 2026, the reported net operating revenue of MXN 10,050,000 and profit before tax and social contribution of MXN 566,828.

(Expressed in thousands of Mexican Pesos, unless otherwise indicated)

(a) Carrying amounts are gross of transaction costs.

Loans and Debentures Measured at Amortized Cost - If the criterion of recognizing these liabilities at their fair value (Level 2) were adopted, the resulting balances would be as follows:

		Consolidated
		06/30/2026								12/31/2025
		Carrying amount				Fair value				Carrying amount				Fair value
Debentures (a)			16,312,042				15,231,834				15,298,505				14,940,398
Loans and financing (b)			4,781,638				4,697,290				4,796,018				4,748,654

(a) Carrying amounts are gross from transaction costs.

Fair values were calculated by projecting cash flows up to the maturity of the transactions based on future rates obtained from public sources (e.g., B3, ANBIMA, and Bloomberg), adding contractual spreads and brought to present value using a pre-fixed rate (pre-DI), plus credit risk components, which considers the ANBIMA triple-A credit curve on the base date as the spread.

20.2 Derivative financial instruments

The main purpose of the operations conducted as of June 30, 2026, is to protect against fluctuations in other indexes and interest rates, without a speculative nature. Accordingly, they are characterized as hedge instruments and recorded at fair value through profit or loss.

The Company contracted and settled NDF (Non-Deliverable Forward) for protection against exchange-rate variation in relation to open balances with supplier Alstom.

All derivative financial instruments were traded over-the-counter (OTC).

A summarized table of derivative instruments contracted for the Company is shown below:

						Reference value								Gross values contracted and settled								Income (loss)
						(Notional)								Received/(paid) local currency								Gain/(loss) in comprehensive income
Operation		Maturity date				2026				2025				2026 Jan - Jun				2025 Jan - Jun				2026 Jan - Jun				2025 Jan - Jun
NDF - foreign exchange risks							-				1,307,174				(41,723	)			-				(41,723	)			-
Assets position			2025				-				1,307,174				(41,723	)			-				(41,723	)			-

20.3 Sensitivity analysis

Sensitivity analyses are established based on assumptions and premises related to future events. The Management of the Company and its subsidiaries regularly review these estimates and assumptions used in calculations. However, the settlement of transactions involving these estimates may result in amounts that differ from estimated amounts, as a result of the subjectivity inherent to the process used to prepare the analyses.

In the sensitivity analysis calculations, new contracts of operations with derivatives were not considered other than the current ones.

For the A and B stress scenarios of the sensitivity analysis, the Company adopted the percentages of 25% and 50%, respectively, which are applied to present the situation showing relevant sensitivity to variable risk.

Total net effect of gains / (losses)		(55,447,624	)	(6,163,754	)	(6,817,596	)	(7,472,121	)
The interest rates considered were (1):
		CDI rate increase	(2)	14.14	%	17.68	%	21.22%
		IPC-A	(3)	1.99	%	2.48	%	2.98%
		TJLP	(4)	9.13	%	11.42	%	13.71%
		CDI rate decrease	(2)	14.14	%	17.68	%	21.22%

(1) The rates presented above served as the basis for the calculation and were used in the 12 months of the calculation:

The assumptions used to determine the discount rates for levels 2 to 4 are detailed below:

(2) Rate as of 06/30/2026, published by B3. The increase in the CDI rate was taken into account to calculate the stress scenarios for both liabilities and investments, so that the total net impact at risk can be observed by offsetting the increase in financial investments against the increase in liabilities.;

(3) Accumulated annual variation in the past 12 months, published by the Brazilian Institute of Geography and Statistics (IBGE);

(4) Rate on 06/30/2026, published by the BNDES;

(5) Rate on 06/30/2026, published by the Central Bank of Brazil;

(6) The exposure amounts do not include adjustments to fair value, are not deducted from transaction costs, and do not consider the balances of interest on 06/30/2026, when they do not affect the calculations of subsequent effects; and

(7) The stress scenarios consider depreciation of the risk factors (CDI rate, Long Term Interest Rate (TJLP), Amplified Consumer Price Index (IPCA), and Special System for Settlement and Custody (Selic) rate).

Acquisition of Companhia de Participações em Concessões (CPC Aeroportos)

(Thousands of Mexican pesos, unless otherwise indicated, except share and per share amounts)

INTRODUCTION

On November 18, 2025, Aeropuerto de Cancún, S.A. de C.V. (the "Issuer"), a wholly owned subsidiary of Grupo Aeroportuario del Sureste, S.A.B. de C.V. ("ASUR" or the "Company"), entered into a share purchase agreement with Motiva Infraestrutura de Mobilidade S.A. (B3: MOTV3) ("Motiva" or the "Seller") to acquire 100% of the shares of Companhia de Participações em Concessões ("CPC Aeroportos"). The acquisition was completed on September 1, 2026 (the "Closing Date") following satisfaction of the conditions precedent, including the required Brazilian airport-sector and antitrust approvals (the "Acquisition").

At the Closing Date, the purchase price for CPC Aeroportos was R$5.1 billion (approximately U.S.$992.2 million), following customary closing adjustments, compared with R$5.0 billion (U.S.$936 million) agreed at signing. The consideration was denominated and settled in Brazilian reais. For purposes of this unaudited pro forma condensed combined financial information, the closing consideration has been translated into Mexican pesos as described in Note 3(ii).

On August 14, 2026, the Issuer, as borrower, and ASUR, as guarantor, entered into a U.S.$1,299 million bridge facility (the "CPC Bridge Facility"). At the closing of the Acquisition, the Issuer drew U.S.$1,230 million under the CPC Bridge Facility to fund the purchase price and related costs. For purposes of this unaudited pro forma condensed combined financial information, the financing adjustments reflect the U.S.$1,230 million actually drawn, presented net of directly attributable issuance costs, with no portion of the purchase price funded with cash on hand. The Interest Period tenor elected and the corresponding Term SOFR fixing are those set out in the executed borrowing and rate-setting documentation.

CPC Aeroportos holds interests in 20 airport concessions in Brazil, Ecuador, Costa Rica and Curaçao. The portfolio includes the Confins and Pampulha airports in Belo Horizonte, the South Block and Central Block airports in Brazil, and the international airports of Quito, San José and Curaçao, and serves more than 45 million passengers per year. Seventeen of the 20 concessions have more than 15 years of remaining concession term. The Acquisition adds four new markets in Latin America and the Caribbean to ASUR's existing operations in Mexico, the United States, Puerto Rico and Colombia.

The following unaudited pro forma condensed combined financial information has been prepared in accordance with Article 11 of Regulation S-X, Pro Forma Financial Information, to illustrate the effects of the acquisition on ASUR's historical consolidated financial statements. The unaudited pro forma condensed combined statement of financial position as of June 30, 2026 gives effect to the acquisition as if it had occurred on June 30, 2026, and the unaudited pro forma condensed combined statements of income for the year ended December 31, 2025 and for the six months ended June 30, 2026 give effect to the acquisition as if it had occurred on January 1, 2025, the first day of the most recently completed fiscal year presented. All amounts are presented in thousands of Mexican pesos unless otherwise indicated.

The acquisition is accounted for as a business combination under the acquisition method in accordance with International Financial Reporting Standard ("IFRS Accounting Standards”) 3, Business Combinations, as issued by the International Accounting Standards Board ("IASB"). ASUR was identified as the accounting acquirer. ASUR prepares its consolidated financial statements in accordance with IFRS Accounting Standards as issued by the IASB.

This unaudited pro forma condensed combined financial information is presented for illustrative purposes only and is not necessarily indicative of ASUR's actual financial position or results of operations had the acquisition occurred on the dates indicated. It is also not a projection of future results. These statements do not reflect any anticipated synergies, operating efficiencies, cost savings or integration costs that may result from the acquisition.

The pro forma information previously furnished in connection with the proposed acquisition was prepared before the Acquisition had closed and reflected the information available at that time. This exhibit applies the acquisition method under IFRS 3 to the completed Acquisition and incorporates the CPC Aeroportos historical information for the year ended December 31, 2025 and for the six months ended June 30, 2026, together with the preliminary purchase price allocation and the financing adjustments described in Notes 4 and 5.

The pro forma information should be read in conjunction with:

● ASUR's Annual Report on Form 20-F for the fiscal year ended December 31, 2025, including the audited consolidated financial statements included in Item 18, and ASUR's unaudited condensed consolidated interim financial statements as of and for the six months ended June 30, 2026, included as Exhibit 99.1 to the Form 6-K furnished to the U.S. Securities and Exchange Commission on September 28, 2026;

● the audited consolidated financial statements of CPC Aeroportos as of and for the year ended December 31, 2025, prepared in accordance with IFRS Accounting Standards as issued by the International Accounting Standards Board (IFRS Accounting Standards), included as Exhibit 99.2 to the Form 6-K furnished to the U.S. Securities and Exchange Commission on September 28, 2026, the unaudited consolidated interim financial information of CPC Aeroportos as of June 30, 2026 and for the six-month period ended June 30, 2026, prepared in accordance with IFRS Accounting Standards as issued by the International Accounting Standards Board (IFRS Accounting Standards), including the requirements of IAS 34, included as Exhibit 99.3 to the Form 6-K furnished to the U.S. Securities and Exchange Commission on September 28, 2026, and ASUR's Report of Foreign Private Issuer on Form 6-K furnished to the SEC on September 1, 2026 announcing the closing of the Acquisition; and

● the accompanying notes to the unaudited pro forma condensed combined financial statements.

The pro forma adjustments presented below are preliminary and remain subject to change. The pro forma financial information is presented as of June 30, 2026 and for the year ended December 31, 2025 and for the six months ended June 30, 2026. The purchase price allocation has not been completed, and the pro forma financing adjustments reflect the Interest Period tenor elected and the corresponding Term SOFR fixing under the CPC Bridge Facility. See Note 7.

NOTES TO THE UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL INFORMATION

(Thousands of Mexican pesos unless otherwise indicated)

NOTE 1 - BASIS OF PRESENTATION

The accompanying unaudited pro forma condensed combined financial information has been prepared in accordance with Article 11 of Regulation S-X using the acquisition method of accounting under IFRS 3 to illustrate the effects of the Acquisition by the Issuer of 100% of the shares of CPC Aeroportos.

The unaudited pro forma condensed combined statement of financial position as of June 30, 2026 gives effect to the Acquisition as if it had occurred on that date. The unaudited pro forma condensed combined statements of income for the year ended December 31, 2025 and for the six months ended June 30, 2026 each give effect to the Acquisition as if it had occurred on January 1, 2025, the first day of the most recently completed fiscal year presented. The Acquisition closed on September 1, 2026; accordingly, the historical information underlying this presentation predates the Closing Date, and the pro forma information does not purport to reflect events occurring between the relevant historical reporting date and the Closing Date, except for the transaction accounting adjustments described herein.

The historical financial information has been derived from the sources described below:

· ASUR historical. Audited consolidated financial statements as of and for the year ended December 31, 2025, included in Item 18 of ASUR's Annual Report on Form 20-F for the fiscal year ended December 31, 2025, prepared in accordance with IFRS Accounting Standards as issued by the IASB; and unaudited condensed consolidated interim financial statements as of and for the six months ended June 30, 2026, prepared in accordance with IAS 34, Interim Financial Reporting, and furnished to the SEC on Form 6-K on July 23, 2026.

· CPC Aeroportos historical. The historical financial information for CPC Aeroportos has been derived from (i) the CPC audited consolidated financial statements for the year ended December 31, 2025, included as Exhibit 99.2 to the Form 6-K furnished to the U.S. Securities and Exchange Commission on September 28, 2026, and (ii) CPC Aeroportos’ unaudited consolidated interim financial information as of and for the six months ended June 30, 2026, which was subject to a review in accordance with International Standard on Review Engagements 2410, “Review of Interim Financial Information Performed by the Independent Auditor of the Entity,” in each case presented in Mexican pesos, included as Exhibit 99.3 to the Form 6-K furnished to the U.S. Securities and Exchange Commission on September 28, 2026.

The unaudited pro forma condensed combined financial information includes certain reclassifications of the historical financial information of CPC Aeroportos presented in the "CPC Aeroportos As reclassified (Note 8)" column, which have been made for the sole purpose of conforming that presentation to the financial statement captions used by ASUR in its consolidated financial statements. Those reclassifications are described in Note 8, which identifies the historical CPC Aeroportos financial statement captions affected, the corresponding amounts reclassified and the purpose of each material reclassification made to conform CPC Aeroportos’ historical presentation to ASUR’s financial statement presentation. They are not transaction accounting adjustments.

The pro forma condensed combined financial information included is for illustrative purposes only and does not represent the actual combined consolidated operating results that would have been achieved had the transaction been completed on the assumed dates, nor is it intended to project ASUR's future combined consolidated operating results or financial position.

Pro forma adjustments

The unaudited pro forma condensed combined financial information includes transaction accounting adjustments that are necessary to depict the accounting for the Acquisition and the related financing in accordance with IFRS Accounting Standards. Following the 2020 amendments to Article 11, transaction accounting adjustments are not required to have a continuing impact on the combined results. The adjustments are presented in two columns: column (A), acquisition and purchase price allocation, and column (B), financing. These adjustments primarily reflect the preliminary application of the acquisition method, including the recognition and measurement of the identifiable assets acquired and liabilities assumed based on management's preliminary estimates.

The preliminary goodwill reflected herein has been determined based on the consideration transferred, the historical carrying amounts of the identifiable net assets acquired and the non-controlling interests, as the fair value measurements required by IFRS 3 have not yet been completed. The preliminary goodwill is subject to change as additional information becomes available, including upon completion of the valuation analyses and the determination of the fair values of the identifiable assets acquired, liabilities assumed and non-controlling interests. IFRS 3 permits a measurement period of up to twelve months from the acquisition date to adjust provisional amounts. Differences between the preliminary estimates and the final purchase accounting may be material.

No management's adjustments reflecting synergies or other expected benefits of the transaction have been presented.

NOTE 2 - ACCOUNTING POLICIES

Both ASUR and CPC Aeroportos prepare their financial information in accordance with IFRS Accounting Standards. Management has performed an initial review of the accounting policies of the Business to identify potential differences from those of ASUR. Based on that initial review, management did not identify differences that would have a material impact on the unaudited pro forma condensed combined financial information, and accordingly no pro forma adjustments related to accounting policy differences have been reflected. That review will be completed as part of the integration of the Business, and any policy alignment identified may result in adjustments to the amounts presented. Certain captions specific to the Business — principally obligations with the concession grantors — do not exist in ASUR's historical statement of financial position and are presented under their own caption in the unaudited pro forma condensed combined statement of financial position, as shown in Note 8(a).

NOTE 3 - PRELIMINARY PURCHASE CONSIDERATION AND GOODWILL CALCULATION

Total preliminary consideration

		June 30, 2026
Purchase price paid at closing (millions of Brazilian reais)		R$	5,100			Note 3(i)
Purchase price paid at closing (millions of U.S. dollars)		U.S.$	992.2			Note 3(i)
USD/MXN exchange rate applied at the acquisition date			17.4693				Note 3(ii)
Total consideration transferred in cash			17,333,039

i. Purchase price paid at closing was R$5,100 million (U.S.$992.2 million), following customary closing adjustments, as announced on September 1, 2026. The price agreed at signing on November 18, 2025 was R$5,000 million (U.S.$936 million).

ii. The consideration was denominated and settled in Brazilian reais. For purposes of this unaudited pro forma condensed combined financial information, the U.S. dollar equivalent of U.S.$992.2 million disclosed in the material event has been translated into Mexican pesos at the USD/MXN closing rate at the balance sheet date presented, resulting in consideration of Ps.17,333,039 as of June 30, 2026 (USD/MXN 17.4693). The resulting implied BRL/U.S.$ rate of the transaction is 5.1401.

iii. The Issuer acquired 100% of the shares of CPC Aeroportos, which was all of the interest held by Motiva. Motiva itself never held 100% of certain underlying concession entities — such as Corporación Quiport S.A. (46.5% interest), the concessionaire of the Quito airport — with the remainder held by third parties. That third-party interest was not part of this transaction and continues to be held by the same third parties. Consistent with the Company's election to measure non-controlling interests at their proportionate share of the acquiree's identifiable net assets under IFRS 3.19, this interest is presented on a provisional basis at the carrying amount already recognized in CPC Aeroportos' historical financial information — a deficit of Ps.479,538 as of June 30, 2026 — pending completion of the underlying fair value measurement, which may result in a material change. See Note 4(A4).

iv. ASUR held no previously owned equity interest in CPC Aeroportos.

v. The amounts currently presented for the acquired assets are provisional and are based on their historical carrying amounts, as no preliminary fair value adjustments have been recognized. Accordingly, the preliminary purchase price allocation currently reflects the consideration transferred compared with the historical carrying amounts of the identifiable assets acquired and liabilities assumed, with the resulting excess presented as preliminary goodwill. The fair value measurement required by IFRS 3 for the airport concession intangible assets has not yet been completed and may result in a material adjustment to the preliminary purchase price allocation, together with the related deferred tax effects. ASUR currently expects this work to be substantially completed within the measurement period permitted under IFRS 3, which cannot exceed one year from the acquisition date.

vi. Bank loans and concession grantor obligations are identified as the principal liabilities to be measured at fair value at the acquisition date. No fair value adjustment has been recognized on a preliminary basis. The fair value of receivables is expected to approximate their contractual amount, and no recoverability concerns have been identified.

vii. Preliminary goodwill of Ps.7,489,400 as of June 30, 2026 represents the excess of the total consideration to be allocated over the identifiable net assets acquired, measured on a provisional basis at their historical carrying amounts. The preliminary goodwill calculation reflects total consideration of Ps.17,333,039 plus the non-controlling interest of Ps.(479,538), which represents a deficit, less identifiable net assets acquired of Ps.9,364,101, resulting in preliminary goodwill of Ps.7,489,400. The amount remains preliminary because the fair value measurements required by IFRS 3 have not yet been incorporated into the allocation and the fair value of the non-controlling interests has not been finalized, and it is not deductible for income tax purposes. Goodwill will be allocated to the relevant cash-generating units and tested for impairment in accordance with the applicable IFRS Accounting Standards. Management believes that the preliminary goodwill recognized in the purchase price allocation is supported by, among other factors, the expected synergies from integrating CPC Aeroportos’ airport concessions with ASUR’s existing portfolio and the strategic expansion into new markets in Latin America and the Caribbean, as described in the Introduction.

Preliminary goodwill calculation

The preliminary goodwill calculation below is based on the historical carrying amounts of the identifiable assets acquired and liabilities assumed and does not yet incorporate the fair value measurements required by IFRS 3. Accordingly, it does not represent a completed purchase price allocation and remains subject to change upon completion of the required valuation analyses.

NOTE 4 - ADJUSTMENTS TO THE PRO FORMA CONDENSED COMBINED STATEMENT OF FINANCIAL POSITION

4 (A1). Consideration paid. Reflects the closing consideration of R$5,100 million (U.S.$992.2 million), translated to Ps.17,333,039 as of June 30, 2026 using the USD/MXN closing rate described in Note 3(ii). The consideration was denominated and settled in Brazilian reais.

4 (A2). Goodwill. Reflects preliminary goodwill of Ps.7,489,400 as of June 30, 2026, presented within intangible assets, airport concessions and goodwill – Net. The amount remains preliminary because the fair value measurements of the identifiable assets acquired and liabilities assumed required by IFRS 3 have not yet been incorporated into the allocation and the fair value of the non-controlling interests has not been finalized. See Note 3(vii).

4 (A3). Elimination of the equity of the acquiree. Reflects the elimination, against the consideration transferred, of the equity attributable to the controlling interests of CPC Aeroportos, amounting to Ps.9,843,639 as of June 30, 2026. The elimination is presented against the individual equity captions of the acquiree — capital stock, capital reserves, other comprehensive loss and retained earnings — and does not extend to the non-controlling interests described in Note 4(A4).

4 (A4). Non-controlling interests. Aeropuerto de Cancún acquired 100% of the interest held by Motiva in CPC Aeroportos; no new non-controlling interest arises at that level. A pre-existing non-controlling interest remains at the level of certain underlying concession entities not wholly owned by CPC Aeroportos, principally Corporación Quiport S.A. (46.5%), since Motiva never held that portion; it was not acquired and continues to be held by the same third parties. Under the Company's election to measure non-controlling interests at their proportionate share of identifiable net assets (IFRS 3.19), this interest is presented on a provisional basis at CPC Aeroportos' historical carrying amount — a deficit of Ps.479,538 as of June 30, 2026 — pending completion of the fair value measurement, and no separate transaction accounting adjustment has been recorded. See Note 3(iii).

4 (A5). Fair value adjustments. No step-up has been recognized on the airport concession intangible assets or on the liabilities identified in Note 3(vi), and no related deferred tax has been recognized. The fair value measurements required by IFRS 3 have not yet been completed and may result in material adjustments to the balances currently reflected in these unaudited pro forma financial statements. Once determined, the step-up will increase intangible assets and deferred tax liabilities in the statement of financial position and potentially, will give rise to incremental amortization over the remaining term of each concession in the statement of income.

4 (A6). Transaction costs. Acquisition-related transaction costs that are not financing costs are expensed as incurred under IFRS 3.53 and do not form part of the consideration transferred or goodwill. As substantially all such costs had already been recognized in the historical financial statements, no material additional adjustment was required, other than the amounts described in Note 5(A2).

4 (A7). Foreign currency translation. Reflects the application of IAS 21 as described in Note 7. Goodwill and any fair value adjustments are recognized as assets and liabilities of the foreign operation and translated at the closing rate; subsequent translation differences are recognized in other comprehensive income.

4 (B1). Acquisition financing. On August 14, 2026, the Issuer, as borrower, and ASUR, as guarantor, entered into the U.S.$1,299 million CPC Bridge Facility. At the Closing Date, the Issuer drew U.S.$1,230 million under the CPC Bridge Facility to fund the purchase price and related costs. The financing adjustment reflects the U.S.$1,230 million actually drawn, recognized net of the directly attributable issuance costs described in Note 4(B2) at an initial carrying amount of Ps.21,290,338 as of June 30, 2026, translated at the USD/MXN closing rate at that date. The facility matures on November 5, 2027 and has no scheduled amortization, with the outstanding principal due in full at maturity, subject to contractual prepayment provisions. Because the facility matures more than twelve months after the balance sheet date presented, the liability has been classified as a non-current bank loan.

4 (B2). Debt issuance costs. The financing adjustment includes costs that are directly attributable to the U.S.$1,230 million drawn under the CPC Bridge Facility described in Note 4(B1), estimated at U.S.$11,271 thousand (approximately 0.92% of the principal). These costs are netted against the carrying amount of the financial liability, which is presented within bank loans in the pro forma statement of financial position, and are subsequently recognized using the effective interest method in accordance with IFRS 9; a straight-line amortization over the tenor of the facility has been used as a proxy for the effective interest method. The resulting amortization forms part of the pro forma finance cost described in Note 5(B1), and its income tax effect is described in Note 5(B2). Acquisition-related costs that are not directly attributable to the financing are accounted for separately under IFRS 3.53 as described in Note 4(A6).

NOTE 5 - ADJUSTMENTS TO THE PRO FORMA CONDENSED COMBINED STATEMENT OF INCOME

5 (A1). Incremental amortization. No adjustment has been recognized because the fair value step-up on the airport concession intangible assets has not been determined. Once determined, incremental amortization will be recognized within the cost of aeronautical and non-aeronautical services over the remaining term of each concession, together with the related deferred tax effect.

5 (A2). Transaction costs. Total acquisition-related transaction costs are estimated at U.S.$1,631 equivalent to Ps.33,459 using the exchange rate as of January 1, 2025, consistent with the pro forma assumption that the Acquisition had been consummated on that date. These costs primarily include legal advisory, due diligence and other professional services directly related to the Acquisition, excluding financing-related costs. Of this total, U.S.$1,547 (Ps.28,229) had already been recognized in the historical financial statements of ASUR and/or CPC Aeroportos, as applicable, as of the respective historical reporting dates. The remaining costs expected to be incurred after the Closing Date are not material. These costs are non-recurring and are not expected to have a continuing impact on the combined results.

5 (A3). Non-controlling interests. No adjustment has been recognized in the allocation of pro forma net income between controlling and non-controlling interests. The non-controlling interests presented are the same non-controlling interests already reflected in the historical results of ASUR and of CPC Aeroportos, and the transaction accounting adjustments in columns (A) and (B) have been allocated in full to the controlling interests because they arise at the level of the Issuer. The allocation will be revisited once the ownership structure of each CPC Aeroportos concession and the fair value of the non-controlling interests have been established. See Note 4(A4).

5 (B1). Pro forma finance cost. The pro forma finance cost is based on the U.S.$1,230 million drawn under the CPC Bridge Facility and comprises interest accrued for the period plus the amortization of the directly attributable issuance costs described in Note 4(B2). It amounts to Ps.1,492,639 for the year ended December 31, 2025 and Ps.756,920 for the six months ended June 30, 2026, and is presented as an increase in interest expense.

The CPC Bridge Facility bears interest at Term SOFR plus a contractual Applicable Margin that increases in 90-day blocks from 125 basis points per annum beginning on the Closing Date to 250 basis points per annum from day 451 through the Maturity Date. Consistent with the pro forma assumption that the financing was in place from the beginning of each period presented, the contractual margin schedule was applied from the beginning of each respective period, resulting in weighted average margins of approximately 163.1 basis points for the year ended December 31, 2025 and 137.4 basis points for the six months ended June 30, 2026. Interest is computed on an Actual/360 basis.

The annual interest rates applied were 3.76% for the year ended December 31, 2025 and 3.76% for the six months ended June 30, 2026, calculated as Term SOFR plus a weighted average contractual Applicable Margin. For purposes of the pro forma adjustments, the CPC Bridge Facility is assumed to have been entered into on January 1, 2025, and the contractual Applicable Margin is applied on a continuous basis from that assumed inception date across all periods presented. Under the CPC Bridge Facility, the Applicable Margin increases in successive 90-day increments, starting at 125 basis points per annum for the first 90 days and stepping up periodically to 250 basis points per annum from day 451 through maturity. Accordingly, the weighted average Applicable Margin for each pro forma period reflects the applicable contractual step-ups based on the number of days elapsed since January 1, 2025, without resetting the Applicable Margin at the beginning of the 2026 interim period. The adjustment reflects the financing as if it had been in place at the beginning of each period presented and does not duplicate financing costs already recognized in the historical information. The financing adjustment also includes the foreign exchange effect of translating the U.S. dollar-denominated facility into Mexican pesos, determined by reference to the USD/MXN rates at the beginning and at the end of each period presented, which results in a foreign exchange gain of Ps.3,145,725 for the year ended December 31, 2025 and of Ps.1,119,423 for the six months ended June 30, 2026. As required by SEC Financial Reporting Manual 3260.1, the following table presents the estimated effect of a hypothetical 12.5 basis point (1/8%) increase or decrease in the assumed Term SOFR rate — holding the contractual Applicable Margin, day-count convention, floor and absence of a credit spread adjustment constant — on pro forma finance cost, pro forma net income attributable to controlling interests and pro forma basic and diluted earnings per share, for each period presented:

		Year ended Dec 31, 2025				Six months ended Jun 30, 2026
Effect on pro forma finance cost (before income tax)			30,254				13,733
Effect on pro forma net income attributable to controlling interests (net of income tax)			21,178				9,613
Effect on pro forma basic and diluted earnings per share			0.071				0.032

5 (B2). Tax effect of the adjustments. Reflects the income tax effect of the financing adjustments described in Note 5(B1), comprising the pro forma finance cost and the foreign exchange effect on the CPC Bridge Facility, computed at the 30% Mexican statutory rate. The net amount recognized is an increase in income tax of Ps.495,926 for the year ended December 31, 2025 and of Ps.108,751 for the six months ended June 30, 2026. The deductibility of interest remains subject to the limitation in Article 28, section XXXII of the Mexican Income Tax Law (30% of adjusted taxable income), which has not been modeled.

NOTE 6 - EARNINGS PER SHARE

No equity instruments were issued in connection with the Acquisition. Accordingly, the Acquisition had no impact on the weighted average number of shares outstanding, and no pro forma adjustment to the weighted average number of shares is required. ASUR had 300,000,000 weighted average shares outstanding for the historical periods presented. Pro forma basic and diluted earnings per share have been computed by dividing pro forma net income attributable to controlling interests by 300,000,000 shares, resulting in Ps.41.207 for the year ended December 31, 2025 and Ps.18.256 for the six months ended June 30, 2026.

NOTE 7 - SIGNIFICANT ASSUMPTIONS, LIMITATIONS AND MATTERS PENDING COMPLETION

The following matters were outstanding at the date of this exhibit and are expected to affect the amounts presented, in certain cases materially:

a. Periods presented. The CPC Aeroportos historical information for the year ended December 31, 2025 has been sourced from the CPC audited consolidated financial statements included as Exhibit 99.2 to the Form 6-K furnished to the U.S. Securities and Exchange Commission on September 28, 2026, and the CPC Aeroportos historical information as of and for the six months ended June 30, 2026 has been sourced from the CPC unaudited consolidated interim financial information, which was subject to a review in accordance with International Standard on Review Engagements 2410, included as Exhibit 99.3 to the Form 6-K furnished to the U.S. Securities and Exchange Commission on September 28, 2026. In each case, the financial information is presented in Mexican pesos.  

b. Exchange rate at the acquisition date. The consideration has been translated from its U.S. dollar equivalent at the USD/MXN closing rate at the balance sheet date presented — 17.4693 at June 30, 2026. The translation of the CPC Aeroportos historical columns uses the closing rate for the statement of financial position and the average rate for the period for the statement of income; those rates, and the BRL/MXN closing rate at September 1, 2026, have been determined by reference to the closing and average rates published for the respective periods. See Note 3(ii).

c. Terms of the acquisition financing. The CPC Bridge Facility has a committed amount of U.S.$1,299 million and was entered into on August 14, 2026. At the Closing Date, the Issuer drew U.S.$1,230 million under the facility. The pro forma adjustments reflect that drawdown and issuance costs of U.S.$11,271 thousand. The facility bears interest at Term SOFR plus the contractual Applicable Margin described in Note 5(B1), computed on an Actual/360 basis, and matures on November 5, 2027 with no scheduled amortization. The contractual margin schedule, day-count convention, 0% Term SOFR floor and absence of a credit spread adjustment are fixed terms of the CPC Bridge Facility. The Interest Period tenor elected and the corresponding Term SOFR fixing are those set out in the executed borrowing and rate-setting documentation. See Notes 4(B1), 4(B2) and 5(B1).

d. Fair value measurements and preliminary goodwill. The fair values of the airport concession intangible assets, the relevant liabilities and the non-controlling interests have not been finalized. The identifiable assets acquired and liabilities assumed have therefore been reflected at the carrying amounts included in CPC Aeroportos’ historical financial information. Accordingly, the goodwill currently presented is preliminary and has been determined based on the consideration transferred, the carrying amounts of the identifiable net assets acquired and the non-controlling interests. The preliminary goodwill will be updated upon completion of the fair value measurements required by IFRS 3. See Notes 3 and 4(A5).

e. Post-closing adjustments. Any purchase price adjustment arising after the Closing Date and any measurement-period adjustment under IFRS 3 will be reflected in accordance with IFRS 3, including through retrospective adjustment of provisional amounts when required.

NOTE 8 - RECLASSIFICATIONS

The historical financial information of CPC Aeroportos has been reclassified in order to conform its presentation to the financial statement captions and the presentation used by ASUR in its consolidated financial statements. The "CPC Aeroportos As reclassified (Note 8)" column of each of the unaudited pro forma condensed combined financial statements presents the financial information of CPC Aeroportos after giving effect to the reclassifications described in this note. The "CPC Aeroportos historical" column of each of the tables below presents the historical financial information of CPC Aeroportos using the captions and amounts included in its financial statements.

These are reclassifications for presentation purposes only. They do not change the historical financial information of CPC Aeroportos for any period presented, and the reclassification column of the statement of financial position table below nets to nil. In the statement of profit or loss tables, each reclassified line nets to nil; the reclassification column as a whole does not, because the CPC Aeroportos historical and CPC Aeroportos as reclassified columns follow different sign conventions for costs, expenses and income tax, as described following those tables. The transaction accounting adjustments arising from the Acquisition and from the related financing are presented separately in columns (A) and (B) of the unaudited pro forma condensed combined financial statements and are described in Notes 4 and 5.

The reclassifications have been determined on a preliminary basis. Upon completion of the review of the accounting policies and of the presentation of the Business described in Note 2, additional reclassifications may be identified and the final presentation may differ from the presentation reflected herein.

The following tables present the reclassifications made to CPC Aeroportos’ historical financial information solely to conform its presentation to ASUR’s financial statement presentation. For each reclassification, the tables identify the originating CPC Aeroportos financial statement caption, the corresponding ASUR financial statement caption, the amount reclassified and the resulting balance. The numbered explanations following the tables describe the nature and purpose of each material reclassification. These reclassifications are presentation adjustments only and do not constitute transaction accounting adjustments.

CPC Aeroportos presents revenue and expense captions that differ from those used by ASUR and presents its statement of profit or loss by nature, whereas ASUR presents its statement of comprehensive income by expense function. The same reclassifications have been applied to both periods presented and are described below; amounts are shown for the year ended December 31, 2025 and for the six months ended June 30, 2026, respectively. Amounts in the CPC Aeroportos historical column are presented with the signs used in CPC Aeroportos’ issued statements of profit or loss, in which costs, expenses and income tax expense are presented as negative amounts and reversals of provisions and allowances are presented as positive amounts. Amounts in the CPC Aeroportos as reclassified column are presented consistent with ASUR’s presentation, in which costs, operating expenses and income tax are presented as positive amounts deducted in arriving at net income, and the components of the comprehensive financing result are presented with their own sign.

(16) Net operating revenue — aeronautical and construction services. CPC Aeroportos presents its revenue in a single caption, net operating revenue, in its statement of profit or loss. Based on the breakdown of net operating revenue disclosed in Note 18 to CPC Aeroportos’ financial statements, airport revenue of Ps.7,678,930 and Ps.4,002,170, which comprises the regulated tariff revenue of the concessions and corresponds to ASUR’s aeronautical services caption, is reclassified to aeronautical services, and construction revenues (IFRIC 12) of Ps.1,521,304 and Ps.794,391 are reclassified to construction services. For the six months ended June 30, 2026, net operating revenue presented in CPC Aeroportos’ statement of profit or loss (Ps.5,022,122) differs by Ps.1 from the total of the breakdown disclosed in its Note 18 (Ps.5,022,121) due to rounding; this difference has been included in aeronautical services, which amount to Ps.4,002,171.

(17) Net operating revenue — other revenue. Reclassification from net operating revenue, based on the same breakdown, of accessory revenues of Ps.387,964 and Ps.187,519, rebalancing revenue of Ps.20,738 and nil, and revenue from services provided among related parties of Ps.29,055 and Ps.38,041, for a total of Ps.437,757 and Ps.225,560, to non-aeronautical services.

(18) Costs of services provided. Reclassification of services, grant cost, depreciation and amortization (depreciation, amortization, and impairment for the six months ended June 30, 2026), personnel costs, materials, equipment and vehicles and other, for a total of Ps.4,067,789 and Ps.2,280,281, to cost of aeronautical and non-aeronautical services, consistent with ASUR’s presentation of operating costs by function. Construction costs of Ps.1,521,304 and Ps.794,391 are reclassified to cost of construction services. The allocation between ASUR’s cost captions and administrative expenses follows the function assigned by CPC Aeroportos in its issued statements of profit or loss: all line items presented within costs of services provided are reclassified to cost of aeronautical and non-aeronautical services or cost of construction services, and all line items presented within operating expenses (administrative and general expenses) are reclassified to administrative expenses (see (19)). No amounts have been reallocated between functions, and the same mapping has been applied to both periods presented.

(19) Operating expenses — administrative and general expenses. Reclassification of personnel expenses; services; materials, equipment and vehicles; depreciation and amortization; non-deductible expenses, provisions and fines; advertising campaigns and events, fairs and newsletters; Rouanet Law, audiovisual, sports and other incentives; (provision) reversal for civil, labor, social security, and contractual risks; travels and lodging expenses; water, electricity, telephone, internet and gas; legal and judicial expenses; contributions to trade unions and class associations; taxes, fees and notary fees; property rentals and condominiums; (allowance) reversal for expected credit losses; and other operating expenses, which CPC Aeroportos presents within operating expenses for a total of Ps.(859,504) and Ps.(369,761), to administrative expenses. (Provision) reversal for civil, labor, social security, and contractual risks of Ps.72 and Ps.71,503 and (allowance) reversal for expected credit losses of Ps.5,551 and Ps.3,993 represent net reversals in both periods and are therefore presented as positive amounts in the CPC Aeroportos historical column, consistent with CPC Aeroportos’ issued statements of profit or loss.

(20) Financial revenues. CPC Aeroportos presents financial revenues in a single caption in its statement of profit or loss, amounting to Ps.403,632 and Ps.199,379. Based on the breakdown disclosed in Note 19 to its financial statements, earnings on financial investments of Ps.327,115 and Ps.146,627 and interest and other financial revenues of Ps.67,104 and Ps.51,328, for a total of Ps.394,219 and Ps.197,955, are reclassified to interest income. The exchange-rate variation on foreign suppliers included in financial revenues is described in (22).

(21) Financial expenses. CPC Aeroportos presents financial expenses in a single caption in its statement of profit or loss, amounting to Ps.(3,431,629) and Ps.(2,016,365). Based on the breakdown disclosed in Note 19 to its financial statements, interest on loans, financing, debentures and commercial notes, inflation adjustments on those instruments and on the obligations with the concession grantors, present-value adjustments on the obligations with the concession grantors and on lease liabilities, losses on derivative transactions and fees, commissions and other financial expenses, in each case net of capitalized borrowing costs of Ps.155,767 and Ps.40,703, for a total of Ps.3,425,141 and Ps.2,017,050, are reclassified to interest expense, the caption used by ASUR for its financing costs. Capitalized borrowing costs are presented net within financial expenses in CPC Aeroportos’ issued statements of profit or loss (Note 19), in accordance with IAS 23, and agree with the capitalization of borrowing costs presented in its statements of cash flows. The exchange-rate variation on foreign suppliers included in financial expenses is described in (22).

(22) Foreign exchange results. Reclassification of the exchange-rate variation on foreign suppliers, which CPC Aeroportos presents within financial revenues and financial expenses, to exchange income on foreign currency and exchange loss on foreign currency, according to whether it represents a gain or a loss. For the year ended December 31, 2025, these amounts comprise a gain of Ps.9,413 and a loss of Ps.(6,488). For the six months ended June 30, 2026, they comprise a gain of Ps.1,424 presented within financial revenues and a net credit of Ps.685 presented within financial expenses, both of which are presented within exchange income on foreign currency for a total of Ps.2,109.

(*) Captions presented by CPC Aeroportos under a name that differs from ASUR’s corresponding caption: equity accounted-investees and current and deferred income tax and social security contribution. These amounts are presented in full under the corresponding ASUR captions, share of results of investments accounted for using the equity method and income tax, respectively. CPC Aeroportos includes its equity accounted-investees within profit before financial result, whereas ASUR presents it after the comprehensive financing result; accordingly, it is presented after that result in the CPC Aeroportos as reclassified column.

The reclassifications described above do not change CPC Aeroportos’ historical net operating revenue of Ps.9,637,991 and Ps.5,022,122, costs of services provided of Ps.(5,589,093) and Ps.(3,074,672), gross profit of Ps.4,048,898 and Ps.1,947,450, operating expenses of Ps.(859,504) and Ps.(369,761), equity accounted-investees of Ps.588,424 and Ps.256,185, profit before financial result of Ps.3,777,818 and Ps.1,833,874, net finance costs of Ps.(3,027,997) and Ps.(1,816,986), or profit for the year and for the period of Ps.631,319 and Ps.41,743, for the year ended December 31, 2025 and for the six months ended June 30, 2026, respectively.

Depreciation and amortization. CPC Aeroportos’ historical depreciation and amortization expense amounted to Ps.813,131 for the year ended December 31, 2025 and Ps.573,420 for the six months ended June 30, 2026.
