EXHIBIT 99.1 News Release First Solar, Inc. Announces Third Quarter 2026 Financial Results, Updates Guidance, and Announces $500 Million Share Repurchase Program • Net sales of $1.23 billion, a decrease of 23% year-over-year • Net income per diluted share of $5.30, an increase of 25% year-over-year • Adjusted EBITDA of $744 million, an increase of 11% year-over-year • Gross cash balance of $1.6 billion and net cash balance of $1.5 billion • First Solar board of directors authorizes $500 million share repurchase program • Contracted sales backlog of 44.0 GW as of September 30, 2026 PHOENIX, Arizona, October 29, 2026 – First Solar, Inc. (Nasdaq: FSLR) (the “Company”), America’s leading PV solar technology and manufacturing company, today announced financial results for the third quarter ended September 30, 2026 and updated its 2026 guidance. Net sales were $1.23 billion for the third quarter of 2026, a 23% decrease compared to the third quarter of 2025, driven primarily by a decrease in the volume of modules sold to third parties. The Company reported third quarter net income of $571 million, or $5.30 per diluted share, compared to $456 million, or $4.24 per diluted share, in the third quarter of 2025. Adjusted EBITDA was $744 million compared to $671 million in the third quarter of 2025. Net cash balance decreased to $1.5 billion as of September 30, 2026 from $2.4 billion as of December 31, 2025, driven by working-capital needs and capital expenditures primarily for our U.S. facilities, partially offset by Section 45X cash receipts and IEEPA tariff refunds received. “Section 232 represents a structural change in how the United States approaches solar manufacturing,” said Mark Widmar, Chief Executive Officer. “As a technology company and the only fully-integrated utility-scale solar manufacturer without dependency on the Chinese crystalline silicon supply chain, we believe we are structurally positioned to benefit from this environment.” Additionally, the Company’s board of directors authorized a share repurchase program of up to $500 million, effective immediately. This authorization reflects confidence in the long-term value of the business while preserving our disciplined approach to capital allocation and ability to continue investing in technology development and growth. The timing and amount of share repurchases will be determined by the Company based on its evaluation of market conditions and other factors. The share repurchase authorization has no expiration date, does not obligate the Company to acquire any particular amount of shares, and may be suspended or discontinued at any time. —————————— See “Non-GAAP Financial Measures” for additional information on Adjusted EBITDA and a reconciliation of Adjusted EBITDA to net income, which is the most directly comparable GAAP measure. 1 1 1 www.firstsolar.com

Our updated 2026 guidance is summarized below: Prior Current Volume Sold 17.0GW to 18.2GW 16.0GW to 17.0GW Net Sales $4.9B to $5.2B $4.6B to $4.9B Gross Profit $2.4B to $2.6B Unchanged Operating Expenses $610M to $635M Unchanged Adjusted EBITDA $2.6B to $2.8B $2.55B to $2.75B Capital Expenditures $0.8B to $1.0B $0.6B to $0.8B Net Cash Balance $1.7B to $2.3B Unchanged —————————— Assumes $2.07 billion to $2.19 billion of Section 45X tax credits and underutilization costs of $110 million to $120 million. Assumes $80 million to $90 million of production start-up expense. Adjusted EBITDA reflects addbacks of approximately $201 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. Net Cash is defined as cash, cash equivalents, restricted cash, restricted cash equivalents, and marketable securities, less expected debt at December 31, 2026. Expected debt excludes factoring arrangements with recourse. From a fourth quarter earnings cadence perspective, we anticipate our module sales to be between 4.3 GW and 5.3 GW, including 3.4 GW to 4.3 GW from our U.S. manufacturing operations. These factors are expected to result in forecasted fourth quarter Adjusted EBITDA between $643 million and $843 million. 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, freight-related costs, and certain factors related to the Inflation Reduction Act of 2022 (the “IRA”), as amended by the One Big Beautiful Bill Act of 2025. 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 third quarter 2026 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, October 29, 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, and amortization (“EBITDA”), EBITDA Margin, Adjusted EBITDA, and Adjusted EBITDA Margin, non‐GAAP measures to provide supplemental information to our U.S. generally accepted accounting principles (“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, and net income margin. 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. 8 www.firstsolar.com

EBITDA Margin and Adjusted EBITDA Margin are calculated as EBITDA and Adjusted EBITDA, respectively, divided by net sales. The most directly comparable GAAP measure is net income margin, calculated as net income divided by net sales. Our presentation of EBITDA, EBITDA Margin, Adjusted EBITDA, and Adjusted EBITDA Margin 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, EBITDA Margin, Adjusted EBITDA, and Adjusted EBITDA Margin 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, EBITDA Margin, Adjusted EBITDA, and Adjusted EBITDA Margin differently than we do because they do not have standardized definitions, which limits their usefulness as comparative measures in relation to other companies.
