First Solar (Nasdaq: FSLR) posts strong 2025 results and raises 2026 EBITDA outlook

Rhea-AI Filing Summary

First Solar, Inc. reported strong 2025 results and issued detailed 2026 guidance. Net sales for 2025 were $5.2 billion, up from $4.2 billion in 2024, driven by a 24% increase in third‑party module volume. Full‑year diluted net income per share rose to $14.21, with fourth quarter diluted EPS of $4.84.

Year‑end 2025 cash, cash equivalents, restricted cash, restricted cash equivalents, and marketable securities, less debt, reached $2.4 billion, helped by proceeds from sales of Section 45X tax credits and strong operating cash flows. Reported 2025 Adjusted EBITDA was $2.36 billion.

For 2026, guidance includes net sales of $4.9 billion to $5.2 billion, Adjusted EBITDA of $2.6 billion to $2.8 billion, volume sold of 17.0 GW to 18.2 GW, capital expenditures of $0.8 billion to $1.0 billion, and an expected year‑end net cash balance of $1.7 billion to $2.3 billion.

Positive

• Strong 2025 growth and profitability: Net sales increased to $5.2 billion from $4.2 billion, full-year diluted EPS reached $14.21, and Adjusted EBITDA was $2.36 billion, showing meaningful scale and earnings expansion.
• Reinforced balance sheet: Year-end 2025 cash, restricted cash, and marketable securities, less debt, rose to $2.4 billion, driven by operating cash flow and monetization of Section 45X tax credits.

Insights

Renewable energy equity analyst

First Solar posts strong 2025 growth and robust 2026 outlook.

First Solar delivered solid 2025 growth, with net sales rising to $5.2 billion from $4.2 billion, mainly on higher third‑party module volumes. Full‑year diluted EPS reached $14.21, and 2025 Adjusted EBITDA was $2.36 billion, indicating strong profitability.

Balance sheet strength improved, as cash, equivalents, restricted cash, and marketable securities less debt increased to $2.4 billion by December 31, 2025, aided by Section 45X tax credit monetization and operating cash flows. This provides flexibility to fund capacity expansions and withstand industry volatility.

For 2026, guidance implies stable to modestly higher revenue of $4.9–$5.2 billion and higher Adjusted EBITDA of $2.6–$2.8 billion. Expected Section 45X tax credits of $2.10–$2.19 billion and planned capital expenditures of $0.8–$1.0 billion highlight ongoing U.S. manufacturing investment under current policy assumptions.

News Release

First Solar, Inc. Announces Fourth Quarter and Full Year 2025 Financial Results and 2026 Guidance

•Net sales of $5.2 billion for 2025 and $1.7 billion for the fourth quarter

•Net income per diluted share of $14.21 for 2025 and $4.84 for the fourth quarter

•2025 year-end gross cash balance of $2.9 billion and net cash balance of $2.4 billion

•2026 net sales guidance of $4.9 billion to $5.2 billion

•2026 Adjusted EBITDA guidance of $2.6 billion to $2.8 billion(1)

•2026 year-end net cash balance guidance of $1.7 billion to $2.3 billion

PHOENIX, Arizona, February 24, 2026 – First Solar, Inc. (Nasdaq: FSLR) (the “Company”) today announced financial results for the fourth quarter and year ended December 31, 2025.

Net sales for the fourth quarter were $1.7 billion, an increase of $0.1 billion from the prior quarter. The increase was primarily driven by an increase in the volume of modules sold in the fourth quarter. Net sales for the full year 2025 were $5.2 billion compared to $4.2 billion in the prior year, driven by a 24% increase in third‑party module volume.

The Company reported fourth quarter net income per diluted share of $4.84 and full year net income per diluted share of $14.21.

Cash, cash equivalents, restricted cash, restricted cash equivalents, and marketable securities, less debt at the end of the fourth quarter increased to $2.4 billion from $1.5 billion at the end of the prior quarter. The increase was primarily the result of additional proceeds received from the sale of our 2025 advanced manufacturing production tax credits under Section 45X of the Internal Revenue Code (“Section 45X tax credits”) and operating cash flows, partially offset by capital expenditures associated with our Louisiana facility.

“Our growth journey continued into 2025, with the commissioning of our new Louisiana factory and our decision to establish a new facility in South Carolina,” said Mark Widmar, Chief Executive Officer. “As we navigated a rapidly evolving environment, we maintained a disciplined approach to contracting and remained anchored in our core principle of pricing and delivery certainty, a key differentiator that our customers value.”

(1)See “Non-GAAP Financial Measures” for additional information on Adjusted EBITDA. As further discussed within our 2026 guidance section, we cannot, without unreasonable effort, predict certain items required to develop the most directly comparable GAAP measure, GAAP net income, and therefore do not provide GAAP net income guidance reflecting these items.

The complete 2026 guidance is as follows:

			2026 Guidance(1)
Volume Sold			17.0GW			to			18.2GW
Net Sales			$4.9B			to			$5.2B
Gross Margin(2)			$2.4B			to			$2.6B
Operating Expenses(3)			$610M			to			$635M
Adjusted EBITDA(4)			$2.6B			to			$2.8B
Capital Expenditures			$0.8B			to			$1.0B
Net Cash Balance(5)			$1.7B			to			$2.3B

——————————

(1)From a first quarter earnings cadence perspective, we anticipate our module sales to be between 3.4 GW and 4.0 GW. We forecast our Section 45X tax credits to be between $330 million and $400 million in the first quarter. These factors are expected to result in forecasted first quarter Adjusted EBITDA between $400 million and $500 million.

(2)Assumes $2.10 billion to $2.19 billion of Section 45X tax credits, and underutilization costs of $115 million to $155 million

(3)Assumes $110 million to $120 million of production start-up expense.

(4)Adjusted EBITDA reflects addbacks of approximately $213 million for share-based compensation, Section 45X tax credit discounts, underutilization, and production start-up expenses. See “Non-GAAP Financial Measures” for additional information on Adjusted EBITDA.

(5)Defined as cash, cash equivalents, restricted cash, restricted cash equivalents, and marketable securities, less expected debt at the end of 2026.

The guidance figures presented above are forward-looking statements that are subject to a variety of assumptions and estimates, including with respect to the impact of public policies such as tariffs, export controls, or other trade remedies and certain factors related to the Inflation Reduction Act of 2022 (the “IRA”) as amended by the One Big Beautiful Bill Act of 2025. Among other things, such factors include (i) the total Section 45X tax credits available to us and (ii) the timing and ability to monetize such credits. Our outlook assumes the current U.S. policy environment persists, and in addition, that permitting processes and timelines will remain consistent with historical levels. Investors are encouraged to listen to the conference call and to review the accompanying materials, which contain more information about First Solar’s fourth quarter and full year 2025 financial results, 2026 guidance, and financial outlook.

We are not providing forward-looking guidance for GAAP net income or a quantitative reconciliation of the Adjusted EBITDA guidance range to GAAP net income, the most directly comparable GAAP measure, because we are unable to predict with reasonable certainty the potential occurrence, financial impact or recognition period of significant items, such as share-based compensation, Section 45X tax credit discounts, contingencies and certain other gains or losses, as well as related income tax accounting because such items have not occurred, are out of our control, and/or cannot be reasonably predicted without unreasonable effort. These significant items are uncertain, depend on various factors, and could have a material impact on GAAP reported results for the guidance period. See “Non-GAAP Financial Measures” for more information on Adjusted EBITDA, including identification of significant items that we believe are not indicative of our ongoing operations.

Conference Call Details

First Solar has scheduled a conference call for today, February 24, 2026, at 4:30 p.m. ET, to discuss this announcement. A live webcast of this conference call and accompanying materials are available at investor.firstsolar.com. A replay of the webcast will also be available on the Investors section of the Company’s website approximately two hours after the conclusion of the call and remain available for 30 days.

Non-GAAP Financial Measures

This press release includes earnings before interest, taxes, depreciation, amortization and accretion (“EBITDA”) and Adjusted EBITDA, non‑GAAP measures, to provide supplemental information to our GAAP results. These non‑GAAP measures are not prepared in accordance with GAAP and should not be considered a substitute for, or superior to, the most directly comparable GAAP measure, net income. Investors should review our financial information in its entirety and not rely on any single financial measure.

First Solar’s management uses these non-GAAP financial measures to better understand and compare operating results across periods. Management believes these non-GAAP financial measures reflect First Solar’s ongoing business in a manner that will allow for meaningful period-to-period comparisons and analysis of trends in First Solar’s business. Management also believes that these non-GAAP financial measures provide useful information to investors and others to understand and evaluate First Solar’s operating results and prospects in the same manner as management.

The following are explanations of each of the adjustments that we incorporate into Adjusted EBITDA, as well as the reasons we add back each of these individual items to determine Adjusted EBITDA:

1.Foreign currency (loss), net: Refers to the net effect of gains and losses resulting from holding assets and liabilities and conducting transactions denominated in currencies other than our subsidiaries’ functional currencies. Foreign currency is excluded because the timing of such currency‑related impacts is uncertain and may obscure underlying operating performance and trends.

2.Other expense, net: Primarily comprises miscellaneous items and financing fees, such as gains/losses on investments or other discrete non‑operating items. These amounts are generally driven by market factors, financing and investment decisions, or one‑time transactions rather than core operations and can be volatile across periods.

3.Share‑based compensation: Is a non‑cash charge reflecting the grant‑date fair value of equity awards recognized over vesting periods. We exclude it because it is significantly influenced by equity program design and stock price volatility, limiting comparability across companies and periods.

4.Section 45X tax credit discounts: When we sell Section 45X tax credits, the cash proceeds received may be less than the notional credit amount due to market pricing, counterparty terms, and payment timing. Economically, this shortfall is akin to a financing cost — the cost of converting a future cash benefit into earlier liquidity — rather than a reflection of underlying manufacturing performance. We therefore exclude these transfer discounts from Adjusted EBITDA to improve comparability across periods and to separate core operating results from financing/monetization decisions.

5.Underutilization (unallocated fixed production overhead): If our plant utilization is abnormally low, the portion of our indirect manufacturing costs related to the abnormal utilization level is expensed as incurred rather than absorbed into inventory. We exclude these costs because they are sensitive to timing, production curtailments, and transitory disruptions.

6.Production start‑up: Consists of costs associated with operating a production line before it is qualified for commercial production, including the cost of raw materials for solar modules run through the production line during the qualification phase, employee compensation for individuals supporting production start-up activities, and applicable facility related costs. Production start-up expense also includes costs related to the selection of a new site and implementation costs for manufacturing process improvements to the extent we cannot capitalize these expenditures. We exclude these costs because they are driven by discrete expansion and launch activities and are not reflective of our ordinary operating performance. These costs are typically incurred over a defined ramp‑up period, can vary significantly based on the timing and scale of new expansions, and may not be indicative of our run‑rate cost structure once a facility or initiative reaches normal utilization levels.

Management believes adjusting our GAAP results for the items described above to determine Adjusted EBITDA is useful to investors in assessing underlying operating performance and comparing period-to-period results, because

these items (i) are largely non‑cash, (ii) can vary significantly based on timing of capacity ramps, start‑ups, and discrete events, or (iii) are not reflective of our ongoing operating cost structure.

Our presentation of EBITDA and Adjusted EBITDA should not be construed as an implication that our actual future results will be unaffected by the items contemplated by the adjustments described above. Our presentation of EBITDA and Adjusted EBITDA has limitations, including (among others):

•it does not reflect all of our cash expenditures;

•it does not reflect changes in our working capital needs;

•it does not reflect the discount on the sale of our Section 45X credits;

•it does not reflect the interest expense on our indebtedness;

•it does not reflect any income tax expenses we may incur or payments we may be required to make; and

•it does not reflect the impact of capacity ramps, start-ups, and discrete charges resulting from certain matters that we believe may not be indicative of our ongoing operations.

Other companies in our industry may calculate EBITDA and Adjusted EBITDA differently than we do because they do not have standardized definitions, which limits their usefulness as comparative measures in relation to other companies.
