Net income swings at Grupo Cibest (NYSE: CIB) as tax and costs rise

Rhea-AI Filing Summary

Grupo Cibest reported first-quarter 2026 net income attributable to shareholders of about COP 1.5 trillion, a sharp rebound from the prior quarter but below 1Q25. Results reflect stronger net interest income and loan growth, partly offset by higher provisions, operating expenses and a new temporary wealth tax.

The consolidated net interest margin improved to 7.03% as higher rates lifted yields more than funding costs. Gross loans reached COP 262 trillion and deposits COP 272 trillion, both growing year-on-year, while asset quality metrics remained manageable despite a modest rise in past-due loan ratios.

Insights

Banking sector analyst

Profit rebounded on stronger core banking income despite tax and cost pressures.

Grupo Cibest generated net income attributable to shareholders of COP 1.46 trillion in 1Q26, reversing a large loss in 4Q25. The key driver was higher net interest income of COP 5.18 trillion as loan portfolio yields rose faster than deposit costs, lifting the consolidated net interest margin to 7.03%.

Asset growth was steady, with gross loans at COP 261.8 trillion and deposits at COP 271.7 trillion. Credit costs eased quarter-on-quarter, with provision charges of COP 1.23 trillion and a cost of credit of 1.90%, while 30‑day and 90‑day past-due ratios of 3.63% and 2.51% indicate contained, though not improving, asset quality.

However, operating expenses increased 24.41% year-on-year to COP 4.04 trillion, driven by a new temporary wealth tax of COP 374 billion and higher personnel costs. Equity fell 8.50% versus 4Q25 to COP 36.4 trillion after a COP 4.3 trillion profit distribution and ongoing share buybacks. Subsequent filings may provide more detail on how these structural taxes and capital actions influence medium-term profitability and capital ratios.

5 terms

Discontinued Operation financial

"it is presented as a Discontinued Operation."

A discontinued operation is a part of a company that has been sold, closed, or is planned to be shut down, and will no longer be part of its ongoing business activities. For investors, it matters because it can significantly affect a company's financial results and future outlook, similar to removing a large, ongoing project from a company's operations. Recognizing discontinued operations helps investors better understand a company's current performance separate from parts that are no longer active.

Net interest margin financial

"The net interest margin for 1Q26 was 7.03%, an increase of 27 basis points"

Net interest margin measures how much a bank earns from lending and investing compared with what it pays for funding, expressed as a percentage of its interest-earning assets. Think of it like a grocery store’s markup: it shows the gap between buying cost and selling price per dollar of goods — here, the cost is interest paid and the sale is interest received. Investors watch it because a higher margin usually means a bank is more profitable and better at managing interest rate and credit conditions.

Cost of credit financial

"a quarterly annualized cost of credit of 1.90%."

The cost of credit is the total price a borrower pays to use someone else’s money, including interest, fees, and any other charges over the life of a loan or credit line. Like the fuel bill for running a business, higher credit costs reduce profits and cash flow, change how much a company can borrow, and affect investor judgments about valuation, risk and future growth prospects.

Wealth tax financial

"a non-recurring effect associated with the accrual of the wealth tax under the new temporary wealth tax decree"

Past due loan ratio financial

"The 30-day past due loan ratio was 3.63% and 2.51% for 90 days."

1Q26

GRUPO CIBEST (NYSE: CIB; BVC: CIBEST AND PFCIBEST) REPORTS FINANCIAL RESULTS

FOR THE FIRST QUARTER OF 2026.

•On December 18, 2025, Grupo Cibest disclosed to the market the execution of a share purchase agreement with Inversiones Cuscatlán Centroamérica S.A. for the sale of 100% of the shares of Banistmo S.A. As a result, Banistmo S.A. must be classified as an Asset Held for Sale, in accordance with IFRS 5 – Non-current Assets Held for Sale and Discontinued Operations, and given that it constitutes a significant line of business, it is presented as a Discontinued Operation. Once the criteria for classifying an asset or group of assets as held for sale are met, the Statement of Financial Position is not restated for prior periods; instead, the corresponding assets and liabilities are presented separately as of the classification date. Additionally, since the criteria for classification as a Discontinued Operation are met, the results of the discontinued operation must be presented separately from those of the continuing operations in the Income Statement, on a comparative basis for all periods presented, which implies restating prior periods.

•Net income attributable to shareholders for 1Q26 was COP 1.5 trillion. This figure represents an increase of 178.66% compared to the previous quarter and a decrease of 16.15% compared to 1Q25. The quarterly annualized return on equity (ROE) of Grupo Cibest was 14.89% for the quarter and 7.65% for the last 12 months.

•The net interest margin for 1Q26 was 7.03%, an increase of 27 basis points compared to 4Q25. Net interest income was COP 5.2 trillion, a 7.00% increase compared to 4Q25 and a 9.15% increase compared to 1Q25.

•Grupo Cibest gross loan portfolio reached COP 262 trillion, representing a 2.14% increase compared to the previous quarter and a 6.50% increase compared to 1Q25. The quarterly increase is mainly due to the performance of the commercial portfolio. Deposits closed 1Q26 at COP 272 trillion, a 2.76% increase compared to 4Q25 and 10.41% compared to 1Q25. The quarterly growth is mainly due to time deposits and savings accounts.    

•Provision charges for 1Q26 amounted to COP 1.2 trillion, representing a 15.54% decrease compared to 4Q25 and a quarterly annualized cost of credit of 1.90%. The behavior of provision expenses is mainly explained by lower spending in the commercial segment, due to higher provision rates for specific clients in the previous quarter. This effect was partially offset by higher expenses associated with updating macroeconomic models. The 30-day past due loan ratio was 3.63% and 2.51% for 90 days.

•Shareholders’ equity attributable stood at COP 36.4 trillion as of March 31, 2026, representing an 8.50% decrease compared to the previous quarter and 10.48% compared to 1Q25. This quarterly change is primarily due to the shareholders' meeting's approval of the profit distribution.

•In terms of digital strategy, a positive trend is observed as of March 31, 2026, Bancolombia had 9.4 million active digital customers on the Mi Bancolombia app (measured over a 30-day period), as well as 28.7 million accounts on Nequi, of which 23.3 million were active.

•For the sole purpose of providing comparability for the analysis of the entity's performance in 1Q26, the document presents the statement of financial position and main indicators of Grupo Cibest as of 1Q26 compared with pro forma statements of previous quarters that exclude the accounting impacts derived from the Banistmo sale agreement.

Total loans, net			232,077,161			243,100,034			248,207,459			2.10			%			6.95			%

During the first quarter of 2026, the gross loan portfolio reached a balance of COP 261,833 billion, representing quarterly growth of 2.14% and an annual increase of 6.50%.

This performance was primarily driven by the growth of the commercial portfolio, which registered an increase of 2.43% in the quarter and 4.47% compared with 1Q25, largely explained by the performance of Bancolombia S.A., with greater activity in the corporate and business segments. Banco Agricola stood out with the highest percentage growth, supported by higher lending in corporate and institutional banking segments, the same drivers behind BAM’s expansion.

The mortgage portfolio continued to show a positive trajectory, with growth of 2.47% compared to the previous quarter and an annual variation of 13.25%. This performance was primarily driven by Bancolombia S.A. In contrast, the mortgage portfolio in Central America showed less dynamism during the quarter.

Meanwhile, the consumer loan portfolio registered moderate growth during the quarter, with a 0.98% increase compared to 4Q25. This performance reflects a more challenging macroeconomic environment, which has led to a more cautious approach to loan origination and slower growth. Performance during the period was mainly driven by credit card, personal loans, payroll loans, and Nequi products. Year-over-year, the consumer loan portfolio grew by 8.52%, primarily due to the performance of Bancolombia S.A., demonstrating that, despite the slowdown observed during the quarter, the portfolio maintains positive growth compared to 1Q25.

At an individual level, Bancolombia S.A. reported quarterly growth of 3.25% in its gross loan portfolio. For its part, Banco Agricola recorded a quarterly increase of 2.52% (measured in USD), and Banco Agromercantil a quarterly increase of 1.07% in its portfolio (measured in USD).

Loan portfolio breakdown by currency and region

1.2. Funding

At the close of 1Q26, customer deposits totaled COP 271,722 billion, representing 77.30% of total liabilities.

This balance increased 2.76% compared to 4Q25 and 10.41% compared to 1Q25. The quarterly growth is mainly explained by time deposits, especially treasury time deposits and digital time deposits, associated with the increase in interest rates due to expectations of a higher benchmark interest rate from the Central Bank. Savings accounts, meanwhile, grew primarily in the institutional segment, also driven by higher interest rates. In contrast, checking accounts showed a quarterly decrease, mainly in the government segment.

Demand deposits remained the main source of funding, accounting for 57.66% of total funding at quarter-end. However, their share declined compared to 4Q25, driven by lower contributions from both savings accounts, which decreased from 47.23% to 46.73%, and checking accounts, which fell from 11.40% to 10.94%. In contrast, time deposits gained a larger share of the funding mix, rising from 32.52% in 4Q25 to 33.61% in the current quarter, an increase mainly due to the higher interest rate offered by this type of deposit. The other funding components remained relatively stable during the period.

1.3. Shareholders’ Equity

Equity attributable to shareholders at the end of 1Q26 was COP 36,377 billion, a decrease of 8.50% compared to 4Q25 and 10.48% compared to 1Q25. This quarterly and year-on-year change is explained by the approval of the profit distribution plan for COP 4.3 trillion on March 24th by the shareholders' meeting.

Likewise, reserves decreased 3.14% in the quarter, mainly attributed to the execution of the share buyback program approved by the extraordinary shareholders' meeting on June 9, 2025, for an amount of up to COP 1.35 trillion, the execution of which began on July 17, 2025. As of March 31, 2026, 50.54% of the approved amount had been executed, which is equivalent to 12,644,634 shares repurchased, of which 54.6% correspond to preferred shares, 40.6% to ADRs and 4.8% to ordinary shares.

The first quarter of 2026 closed with a net profit of COP 1,457 billion, equivalent to COP 1,535 per share (USD 1.68 per ADR). This result was primarily driven by the performance of net interest income, due to higher loan portfolio returns. However, the profit for the period was impacted to a greater extent by a non-recurring effect associated with the accrual of the wealth tax under the new temporary wealth tax decree, established by Legislative Decree 0173 of February 24, 2026, issued by the National Government under the state of economic, social, and ecological emergency.

The quarterly annualized return on equity (ROE) of Grupo Cibest was 14.89% in the first quarter of 2026 and 7.65% for the last 12 months.

2.1.Net Interest Income & Net Interest Margin

Net interest income reached COP 5,182 billion in 1Q26, an increase of 7.00% compared to 4Q25 and 9.15% compared to 1Q25. This growth was mainly due to higher interest income resulting from increased returns on the consumer and mortgage loan portfolios, due to the increase in the Central Bank's benchmark interest rate.

While the higher interest rate exerted pressure on the cost of funds for savings accounts and time deposits at Bancolombia S.A., interest expenses grew at a slower pace than income generated by productive assets. This difference contributed positively to the expansion of net interest income during the quarter.

The annualized weighted average cost of deposits was 3.97% in 1Q26, representing an increase of 6 basis points compared to 4Q25.

The loan portfolio NIM stood at 7.84% during the quarter, representing an increase of 27 bps compared to 4Q25 and 60 bps compared to 1Q25, reflecting the greater expansion of asset returns relative to the cost of funds. Meanwhile, investment NIM reached 1.82%, an increase of 33 bps compared to 4Q25, explained by a larger average portfolio size and higher income from debt securities valuations. On an annual basis, there was a decrease of 86 bps compared to 1Q25, considering that during that period there were lower levels of devaluation in the zero-coupon yield curves. As a result, the consolidated NIM stood at 7.03%, an increase of 27 bps compared to 4Q25 and 39 bps compared to 1Q25.

2.2.        Fees and Income from Services

Net income from fees and other services in 1Q26 was COP 1,251 billion, representing a 0.86% decrease compared to 4Q25 and a 30.15% increase compared to 1Q25.

Fee income registered a quarterly decrease of 9.68%, mainly due to slower growth in bancassurance and in fees associated with debit and credit card billing compared to 4Q25, a quarter that traditionally exhibits greater seasonality. However, strong performance was maintained in card issuance and distribution during 1Q26. This variation was partially offset by the improved performance of banking services at Bancolombia, related to electronic services, and at BAM, due to billing and transaction management services. On an annual basis, debit and credit card fees registered significant growth, which, along with the strong performance of banking and bancassurance services, drove an 11.83% increase in fee income compared to 1Q25.

Meanwhile, fee expenses decreased by 21.3% quarter-on-quarter and 9.33% year-on-year. The variation observed in both periods is mainly due to the reclassification of fee expenses related to sales, collections, and other services, which were reclassified as operating expenses, starting in 2026.

1Q26

*Figures in billions

2.3.        Other operating income

Total other operating income reached COP 854.7 billion in 1Q26, representing a 22.2% decrease compared to 4Q25. This quarter-over-quarter change was mainly attributable to lower income from foreign exchange derivatives due to greater devaluations of the swap curve, as well as lower foreign exchange gains reflecting the normalization of realization income from the foreign exchange portfolio, which had shown exceptional performance in the last quarter of 2025.

On an annual basis, this item registered a 3.28% increase, mainly due to improved performance of realization income compared to 1Q25.

Gains on the sale of assets declined on a quarter-over-quarter basis, primarily due to mark-to-market valuation income from investment funds recognized in 4Q25, which was not recorded in 1Q26.

2.4. Dividends received, and share of profits of equity method investees

Total dividends and other net income from equity investments closed at COP 131 billion in 1Q26, representing a decrease of 58.43% compared to 4Q25 and 3.73% compared to 1Q25. The quarterly variation is mainly explained by a base effect associated, on the one hand, with the partial recovery of the impairment recorded in the investment in Tuya S.A. during the last quarter of 2025 and, on the other hand, with the dividends received from Viva Malls, an investment vehicle included in the Colombia Real Estate Fund FIC, which were also recognized in 4Q25.

2.5.         Asset Quality and Provision Charges

At the end of 1Q26, the principal balance for past due loans (those that are overdue for more than 30 days) totaled COP 9.237 billion, equivalent to 3.63% of the total gross portfolio, while 90-day past-due totaled COP 6.384 billion, representing 2.51%. The growth in the 30-day ratio is associated with consumer and mortgages, and the stronger origination activity in recent quarters. Despite the deterioration of macroeconomic expectations in Colombia, all portfolios showed resilient performance during the quarter.

The coverage, measured by the ratio of allowances for loan losses (principal) to past-due loans (30 days overdue), was 132.69% at the end of 1Q26, lower than the 1    34.41% recorded in 4Q25. Loan deterioration (new past-due loans including write-offs) totaled COP 1,290 billion, higher when compared to 4Q25. The increase in new NPL formation, consistent with the rise in the 30-day NPL ratio, is by origination dynamics tied to a strategy focused on higher risk-adjusted returns. In contrast, write-offs decreased during the quarter, continuing the trend observed in the previous period.

Provision charges (after recoveries) totaled COP 1,229 billion in the quarter, representing a 15.54% decrease compared to the previous quarter. This performance is explained by lower expenses associated with the commercial segment and certain specific clients, when compared with the previous quarter. In contrast, higher spending was observed due to the updated models, which incorporated a deterioration in Colombia's macroeconomic outlook for 2026.

8

1Q26

Provisions as a percentage of the average gross portfolio, quarterly annualized, was 1.90% in 1Q26 and 1.81% over the last 12 months, representing a decrease of 41 basis points compared to the previous quarter and an increase of 19 basis points compared to 1Q25. Loan loss provisions (for the principal) totaled COP 12,257 billion, representing coverage equivalent to 4.82% of the gross loan portfolio.

The performance of Stages 2 and 3, which remained stable during the quarter, demonstrates that the portfolio has responded adequately to the deterioration containment strategies derived from the risk appetite defined for the segments and sectors with the greatest exposure in recent years.

2.6.        Operating Expenses

During 1Q26, operating expenses totaled COP 4,044 billion, representing an increase of 6.77% compared to 4Q25 and 24.41% compared to 1Q25. Operating efficiency closed at 54.51% in the quarter and 50.88% over the last 12 months..

Personnel expenses (salaries, employee benefits, and bonuses) totaled COP 1,554 billion in the quarter, representing an increase of 6.48% compared to 4Q25 and 10.18% compared to 1Q25. In both cases, the increase is mainly explained by the annual salary adjustment applied at Bancolombia S.A.

General expenses totaled COP 2,491 billion in the quarter, registering a 6.95% increase compared to the previous quarter and a 35.32% increase compared to 1Q25. Both increases are mainly explained by the provision for wealth tax, incurred in Bancolombia S.A. and the other Colombian subsidiaries in February, amounting to COP 374 billion. Other administrative expenses related to business transformation decreased in the first quarter due to seasonal effects, as these types of costs tend to increase gradually toward the end of the year. During the quarter, expenses associated with collections and customer service, previously recorded as commission expenses, were reclassified. The reclassified amount for the quarter totaled COP 102 billion. Going forward, these items will continue to be presented as operating expenses and not as commission expenses.

As of March 31, 2026, Grupo Cibest had 33,588 employees, 795 branches, 5,803 ATMs, 34,949 banking correspondents and more than 33 million customers.

*Figures in billions

2.7.        Taxes

Cibest Group's income tax expense was COP 710 billion, resulting in an effective tax rate of 33%. The increase in the effective rate was primarily due to the recognition of the wealth tax, established for legal entities by Decree 173 of February 24, 2016, issued within the framework of the economic, social, and ecological state of emergency declared on February 11, 2016. This tax is recognized in the accounting records as part of operating expenses; however, since it is not deductible for income tax purposes, it does not reduce the taxable base, thus increasing the effective tax rate for the period. Even so, the effective rate continues to reflect the combination of tax benefits in force in the different geographies where the Group operates, among which in Colombia the exempt income associated with

1Q26

the mortgage portfolio for social housing and investments in productive fixed assets stand out, as well as the tax benefits in Guatemala, El Salvador and Panama, related to exempt income from the returns of securities issued by those governments.

3.BREAK DOWN OF PRINCIPAL OPERATIONS

The following tables summarize the financial statements of our operations in each country.

BANCOLOMBIA S.A. (STAND ALONE) – COLOMBIA

In 2026, Colombia faces a complex environment marked by external and internal shocks. Globally, geopolitical conflicts have increased financial volatility through disruptions in energy supply and heightened risk aversion, while locally, fiscal deterioration and electoral uncertainty have put upward pressure on the sovereign risk premium. Against this backdrop, the economy has continued in a phase of macroeconomic stabilization, with GDP growth of 2.6% in 2025, primarily driven by household consumption and public spending. However, this growth has an unfavorable composition due to weaker private investment, which has kept the fixed investment rate low compared to pre-pandemic levels. Simultaneously, inflation has accelerated above 5% in the first months of 2026, fueled by a sharp increase in the minimum wage and risks associated with rising energy costs, increasing the likelihood that it will exceed 6% in the second half of the year. In response, the Central Bank has resumed a cycle of interest rate hikes, reaching 11.25%, prioritizing a contractionary and prudent stance aimed at containing inflationary pressures and anchoring expectations, despite divided opinions. All of this is occurring within a challenging fiscal framework, following the activation of the Fiscal Rule's escape clause, which has pushed the deficit to 6.4% of GDP and gross debt to nearly 65% of GDP by the end of 2025. Even so, the country is expected to gradually move toward greater stabilization of its main macroeconomic indicators.

In this context, Bancolombia S.A.'s loan portfolio grew 3.26% in 1Q26 compared to the previous quarter. This growth was primarily driven by the commercial loan portfolio, thanks to the dynamism of the corporate segment, especially in January, associated with clients who brought forward their loan applications in anticipation of a central bank increase in the benchmark interest rate. Additionally, disbursements increased due to the severance pay campaign, aimed at financing this benefit payment to employees. The consumer loan portfolio maintained positive performance, although at a slower pace than in previous quarters, with Nequi, personal loans, and payroll loans standing out. Meanwhile, the mortgage portfolio continued the positive growth trend observed over the previous two years.

Regarding deposits, the total balance increased by 3.133% during the quarter, mainly due to the stronger performance of time deposits, especially treasury certificates of deposit (CDs) and digital time deposits. This performance was associated with higher interest rates, amid expectations of a higher benchmark interest rate from the Central Bank of Colombia (Banco de la República). Savings accounts saw growth concentrated in the institutional segment, also driven by higher interest rates. In contrast, checking accounts experienced a quarterly decrease, primarily due to the government segment.

Bancolombia S.A.'s net income in 1Q26 reached COP 1.31 trillion, representing a 0.18% increase compared to 4Q25. Net interest income increased, mainly due to higher loan portfolio income, driven by a higher rate of return on the commercial loan portfolio. Income

11

1Q26

from consumer and mortgage loan portfolios also increased as a result of a higher average balance during the quarter. To a lesser extent, treasury income also increased, mainly due to higher income from debt securities valuations. This trend was partially offset by an increase in interest expenses, primarily resulting from higher interest rates on savings accounts and time deposits. The net interest margin (NIM) was 7.49% for 1Q26, compared to 7.04% in 4Q25.

Provision expenses decreased during the quarter, mainly due to lower spending in the corporate and SME segments. In contrast, higher expenses related to macroeconomic models were observed, as a result of updated risk models that incorporated new macroeconomic projections. These projections include a higher benchmark interest rate and inflation at year-end, as well as lower GDP growth expectations than previously estimated. The cost of credit stood at 1.97%, decreasing 29 basis points compared to 4Q25 due to a provision made in the previous quarter related to a deterioration in the macroeconomic outlook.

Net commissions registered a quarterly increase, mainly due to a greater reduction in expenses compared to income. This behavior is largely due to the reclassification of collection and telephone channel expenses to operating expenses. Within the latter, the strong performance of debit and credit card commissions stands out, associated with the increase in the number of cards issued.

Operating expenses increased compared to the previous quarter, primarily due to the provision for the wealth tax established by the national government.

Finally, the annualized quarterly ROE was 19.15% for the quarter.

The core solvency ratio was 11.14%, and the total solvency ratio was 13.15%. The decrease compared to the previous quarter is mainly due to dividends declared to Grupo Cibest.

The statement of financial position, income statement, and main indicators of Bancolombia S.A. are presented below. The 1Q26 cut-off is compared with pro forma figures from previous quarters, assuming the improvement of the corporate evolution towards Grupo Cibest in those cut-offs respectively, with the sole purpose of providing comparability for the analysis of the entity's performance in 1Q26.

1Q26

BANAGRICOLA- EL SALVADOR

Economic activity in El Salvador saw a marked acceleration in growth last year, reaching 3.9% from 2.6% in 2024. This performance was driven by a 24.7% increase in construction, boosted by the ongoing implementation of more than 120 infrastructure projects expected to be completed around 2028-2030. Regarding prices, although inflation has remained low in recent years, pressures from higher fuel and fertilizer prices could lead to temporary increases in costs for both consumers and producers. In the external sector, an expected slowdown in remittances starting this year could limit households' ability to further increase their consumption; meanwhile, exports could benefit somewhat from the tariff agreement reached with the United States, which puts the country in a better position relative to its main competitors. However, uncertainty remains regarding the evolution of the conflict in the Middle East and the disruptions it may cause to international trade. Therefore, the most optimistic growth forecasts for the country are based primarily on favorable domestic dynamics, thanks to the positive spillover effects of the construction sector on private employment, financial activities, and commerce—a trend expected to continue throughout the forecast period.

Against this backdrop, Banco Agrícola's loan portfolio closed the quarter with 2.52% growth (measured in USD), driven by the commercial loan portfolio, particularly in the corporate, construction, institutional, and business segments, reflecting increased lending activity in larger-scale transactions. Additionally, the growth in the consumer loan portfolio was mainly due to personal loans and credit cards, associated with greater use of these products by individual customers. On the deposit side, growth was also recorded, driven by improved performance in savings accounts for both individuals and businesses, as well as increased use of digital channels. Current accounts increased, driven by higher balances in the institutional and government segments. In contrast, time deposits decreased, associated with slower activity in the corporate segment in response to adjustments in deposit rates.

Banco Agrícola's net income for 1Q26 was COP 118.5 billion, a 23.33% decrease compared to 4Q25. Net interest income decreased compared to the previous quarter, primarily due to lower income from treasury operations related to the normalization of positive valuations recorded in the previous quarter and lower yields on sovereign bonds. On the expenses side, a decrease was observed, associated with lower costs for time deposits. The net interest margin for 1Q26 was 6.90%, representing a decrease of 107 basis points compared to 4Q25.

Net provisions for the period increased, associated with lower recoveries in the collection management of portfolios with a higher risk appetite in the retail segment. Consequently, the cost of credit was 2.02% for the quarter, an increase compared to 4Q25. Provisioning trends are aligned with the increase in non-performing loan levels across higher-risk portfolios. However, these levels remain within the bank’s risk appetite.

Net commissions decreased, primarily due to lower revenues from credit and debit cards, as well as remittances, and a base effect resulting from a reclassification of other income to commission income in 4Q25, which was normalized in 1Q26.

Operating expenses also decreased compared to the previous quarter, mainly due to lower overhead costs. This is largely attributable to the normalization of amortization and depreciation, which typically peak in the fourth quarter, associated with the activation of development projects and other non-recurring accounting entries. Additionally, maintenance expenses decreased.

Finally, the annualized quarterly ROE was 20.53%.

The total solvency ratio was 13.60%. The increase compared to the previous quarter is mainly due to the appropriation of retained earnings and current-quarter earnings.

1Q26

GRUPO AGROMERCANTIL HOLDING – GUATEMALA

The country has shown one of the best performances in the Central American region in recent years, driven by solid growth in financial activities and resilient exports, with the economy expanding by 4.3% last year. On the price front, although inflation has consistently remained below the Bank of Guatemala's 4.0% target, rising energy prices stemming from the conflict in the Middle East are expected to put upward pressure on the indicator in the short term. Looking ahead, the economy is expected to maintain a favorable trajectory, as increased investment in infrastructure projects and tourism offset the potential reduction in remittances resulting from a more restrictive immigration policy in the United States. In line with this outlook, President Arévalo's administration has demonstrated a greater willingness to increase spending on infrastructure and social programs, and it is estimated that public administration spending will provide an additional boost to growth. However, it is important to highlight that Guatemala has historically been characterized by its fiscal strength and that, while there are plans to expand spending, a slight deterioration in public finances over the next few years would not be perceived as an alarming factor by analysts and rating agencies. Finally, in this context, Fitch Ratings raised the country's rating to BB+ last October, placing it one step away from achieving investment grade with the three major agencies, a decision anticipated to be made this year.

BAM's loan portfolio closed 1Q26 with a 1.07% increase in USD terms, explained by greater lending activity in commercial transactions. In consumer lending, personal loans registered a decrease driven by a more cautious lending appetite, partially offset by the strong performance of credit cards and other products. Meanwhile, the mortgage portfolio showed a decrease. As for deposits, savings and checking accounts showed positive growth. While time deposits declined, primarily in the institutional segment.

BAM's net income for 1Q26 was COP 81.8 billion, representing a 300.09% increase compared to the previous quarter.

Net interest income decreased by 5.21% quarter-on-quarter, primarily due to lower portfolio income associated with a shorter accrual period, the aforementioned dynamics of the consumer portfolio, and lower treasury income from the valuation of securities with the Government of Guatemala. Meanwhile, interest expenses decreased by 11.36%, explained by lower costs on time deposits, in line with their lower balance and maturities in the institutional segment, as well as lower interest on loans from financial institutions following amortizations made during the quarter.

Provisioning performance at BAM reflected the improvement in asset quality, as both 30-day and 90-day NPL ratios declined. Provision expenses decreased compared to the previous quarter, as a result of less impairment pressure, mainly in personal loans. In this context, the cost of credit for 1Q26 was 1.63%, decreasing compared to 4Q25 and 1Q25.

Fees contributed positively to income generation, mainly associated with syndicated loans and structured transactions.

Operating expenses decreased compared to the previous quarter, driven by lower labor costs associated with plant optimization, as well as a reduction in overhead expenses, particularly depreciation and marketing, along with efficiencies resulting from the optimization of the operating structure.

Finally, the annualized quarterly ROE was 16.21%.

The core solvency ratio was 7.26%, and the total solvency ratio was 12.49%. The decrease compared to the previous quarter was mainly due to dividends declared and approved.

1Q26

BANISTMO- PANAMA

Panama's economy grew by 4.4% in 2025, exceeding our forecast of 4.1%. This performance continues to be driven by the productive activity of the logistics sector, led by the Panama Canal, whose operations efficiently weathered the pressures on international trade generated by US tariff policy. Household consumption supported the trade and financial sectors, which ended the year with growth of 3.6% and 5.2%, respectively. Tourism remained robust, boosting restaurant and hotel production to 5.9%, while construction showed a recovery during the last quarter of the year, reaching an expansion of 2.7%. As such, both the IMF and the World Bank maintain optimistic projections for the Panamanian economy: the IMF forecasts growth of 3.8% for 2026, while the World Bank projects 3.9%.

In this context, Banistmo’s loan portfolio ended the quarter with a 1.50% decrease, measured in U.S. dollar terms. This performance reflects contractions in both the commercial and mortgage portfolios.The mortgage portfolio also declined, as loan disbursements during the period did not offset repayments and amortizations. In contrast, the consumer portfolio showed growth, mainly driven by the performance of general-purpose loans and auto loans.Regarding deposits, balances increased, primarily reflecting higher levels in both time and demand deposits.Time deposits increased mainly in the retail and SME segments, while demand deposits showed improved performance, driven by savings and checking accounts, particularly within the retail, preferred and corporate segments.

Banistmo's net income for 1Q26 was COP 100.6 billion, representing a 129.28% increase compared to the previous quarter. Net interest income decreased, primarily due to lower interest income, which fell as a result of reduced loan portfolio income, affected by a lower average loan volume. This performance was partially offset by a greater contribution from the treasury portfolio, driven by liquidity operations. Meanwhile, interest expenses decreased, associated with lower costs on time deposits and bonds. The net interest margin for 1Q26 was 3.03%, slightly lower than the 3.05% recorded in 4Q25.

Regarding net loan loss provisions, there was a decrease compared to the previous quarter, mainly due to a seasonal effect associated with the suspension of personal loan repayments at year-end, which allowed the period to begin with lower delinquency rates and provisioning requirements. This performance was partially offset by a one-off increase resulting from the deterioration of a client in the corporate segment.

Operating expenses decreased compared to the previous quarter, primarily due to lower overhead costs associated with reductions in fees, professional services, marketing, and other operating expenses, as well as the exclusion of amortization and depreciation expenses in accordance with regulations applicable to discontinued operations. Additionally, there was a decrease in bonuses due to adjustments in provisions, which was partially offset by an increase in labor expenses related to higher salary costs.

Finally, the annualized quarterly ROE was 8.97%.

The core solvency ratio was 13.14%, and the total solvency ratio was 15.01%. The increase compared to the previous quarter is mainly due to the decrease in the loan portfolio.
