First Solar, Inc. (FSLR) | The Buildout — AI Infrastructure
The Verdict
First Solar makes cadmium-telluride thin-film solar modules and sells them to developers and large power buyers. The AI buildout reaches the company through a single channel: data-center electricity demand creates demand for new utility-scale solar, and those projects need modules. First Solar supplies the modules, not the batteries or inverters. Its scarce asset is not solar capacity in the abstract but U.S.-made modules with a domestic bill of material that do not depend on Chinese crystalline-silicon supply chains, a compliance input that hyperscaler-backed projects need.

What We Like
- Contracted backlog of 45.1 GW worth $13.6B at June 30, 2026, with deliveries scheduled through 2030, and the U.S. manufacturing fleet described as substantially committed through 2028.
- 41 of the 45 GW of backlog carries some form of domestic-content requirement, tying the order book to U.S. policy.
- Q2 2026 gross margin of about 57% and adjusted EBITDA of $644M, a 61% adjusted EBITDA margin.
- Up to $0.6B of contingent CuRe adjuster revenue sits across 23.4 GW of contracts, the majority expected in 2027 and 2028.
- Cash and short-term investments of $1.73B against $194M of total debt, after the India DFC loan was fully prepaid.
What We’re Watching
- Section 232 implementation terms. The company applauded a 2026-08-06 polysilicon action, but the source material does not describe the floor price, waivers, or quotas that management says govern bookings, ASPs, and the Southeast Asia decision.
- The Southeast Asia capacity decision on roughly 1.8 GW of fully finished international capacity, held pending Section 232; the 10-Q flags impairment risk on international equipment and facilities.
- Margin quality, specifically whether the estimated $89M net IEEPA tariff benefit repeats, refines, or reverses. Management calls it subject to refinement.
- South Carolina finishing facility: phase 1 production start guided to H2 2026; phase 2 completion moved out to mid-2027.
Operating momentum is intact, with record sales volume, a 57% gross margin, and adjusted EBITDA above the high end of its preview range. But the case now turns on policy rather than execution. Guidance has been reaffirmed twice without a raise despite those beats, and backlog slipped sequentially from 47.9 GW to 45.1 GW as management held U.S. bookings. The open question is whether Section 232 terms land strongly enough to convert roughly 4 GW of sidelined demand into firm, higher-priced orders.
Earnings
In Q2 2026, the quarter ended June 30, First Solar reported net sales of about $1.06B, down about 4% year over year. Management attributed the decline mostly to lower prior-year contract-termination revenue rather than weaker demand, and reported record Q2 and first-half sales volume. Gross margin reached about 57%, up roughly 12 percentage points, helped by an estimated $89M net IEEPA tariff benefit, a higher mix of modules qualifying for Section 45X credits, and lower logistics costs. Net income was $423M, and adjusted EBITDA was $644M, above the high end of the company's $400-$500M preview range. The quarter also carried the company past 100 GW of cumulative module sales.

those 3 projects that have been announced recently are about 5 gigawatts of capacity. Half of that volume of that 5 gigawatts I referenced is directly communicated and tied to Google as a hyperscale. The other 2.5 gigs, they have not disclosed the counterparties.— Mark Widmar, CEO, 2026-07-30
Management tone: Management came across confident on operations but patient and non-committal on policy. The shift from the Q1 2026 call to the Q2 2026 call was about policy visibility, not performance: in April management said Section 232 clarity was expected most likely in Q2 2026, and by July the CEO said, "I cannot give you any level of confidence maybe more than what you have right now." Guidance was held steady across both quarters despite beats. Management was candid on cost pressure and on the Southeast Asia underutilization, and firm in opposing waivers or quotas under Section 232.
Management Guidance
For full-year 2026, management reaffirmed the guidance ranges shown above. Assumptions include $2.10B-$2.19B of Section 45X tax credits and $115M-$155M of underutilization costs. On the Q2 2026 call, management initiated Q3 2026 guidance of 3.9-4.5 GW of volume and $625M-$775M of adjusted EBITDA, and updated its net tariff impact assumption to $60M-$80M.
Trajectory
Revenue has come down from the record quarters of late 2025, when it reached $1,595M in the September quarter and $1,683M in December, to roughly $1.05B in each of the last two quarters. The Q2 year-over-year decline of about 4% reflects lower prior-year contract-termination revenue rather than softer volumes, and management reported record Q2 and first-half sales volume. The gross margin line moved the other way, from 46.6% in Q1 2026 to 57.3% in Q2 2026. Part of that step is policy rather than operations, alongside a higher mix of 45X-qualifying modules and lower logistics costs.
The Model
The model projects FY+1 revenue of $5.10B and EBITDA of $2.42B, a 47.5% margin, and FY+2 revenue of $6.35B and EBITDA of $3.08B, a 48.5% margin. The near term is anchored by the 45.1 GW contracted backlog and the back-half weighting of the 2026 volume plan of 17.0-18.2 GW, against roughly $2.10B of revenue recorded in the first half. FY+2 depends on converting sidelined U.S. bookings, the South Carolina finishing line ramping from its H2 2026 phase 1 start, and CuRe adjuster revenue arriving mostly in 2027 and 2028.

What Could Go Right — and Wrong
- Section 232 lands with a floor price and without meaningful waivers or quotas, unlocking the roughly 4 GW of sidelined U.S. demand.
- CuRe adjusters convert from notifications into recognized revenue, up to $0.6B across 23.4 GW of contracts, majority in 2027 and 2028.
- The roughly 1.8 GW of idled Malaysia and Vietnam capacity returns to earning, ending the approximately $30M per quarter underutilization drag.
- South Carolina finishing phase 1 starts production in H2 2026 and phase 2 completes in mid-2027, lifting domestic-content supply.
- The perovskite Series 6 pilot line reaches operational readiness in 1H 2027 at up to 1 GW of capacity.
- Section 232 arrives with waivers or quotas that dilute the strategic intent, which management says would compress the policy premium.
- The $89M net IEEPA tariff benefit refines downward, or commodities and freight keep rising; management calls the input-cost environment one of the most challenging it has faced.
- The Southeast Asia decision becomes a shutdown with an impairment, turning the roughly $30M per quarter drag into a one-time charge.
- Backlog keeps slipping from 47.9 GW as the pause in U.S. bookings persists.
- Competitors add U.S. crystalline-silicon capacity. Canadian Solar, T1 Energy, and Tesla all point that way, competing for the same domestic-content premium.
Looking Ahead
The next year turns on Section 232. The company endorsed a 2026-08-06 action on polysilicon and derivatives, but management had waited all year for terms, and the source material does not describe them. Strong terms would let three things happen: the Southeast Asia capacity decision, conversion of the sidelined U.S. bookings, and clearer pricing into 2029 and 2030. Weak terms point the other way. Discrete, dated commitments to check include the South Carolina finishing phase 1 production start in H2 2026, the CuRe launch in India in early 2027, the perovskite pilot line's operational readiness in 1H 2027, South Carolina phase 2 in mid-2027, and CuRe replication running through 1H 2028.
- H2 2026South Carolina phase 1 — Finishing facility production start; tests the reshoring plan.
- End of 2026Sidelined bookings convert — ~2 GW under CP plus ~2 GW in talks may become firm backlog.
- Early 2027CuRe launch in India — First Series 6 Indian line converted to the CuRe upgrade.
- 1H 2027Perovskite pilot line — Up to 1 GW pilot reaches operational readiness in Perrysburg.
- Mid-2027South Carolina phase 2 — Completion slipped to mid-2027 to fold in CuRe earlier.
- 1H 2028CuRe replication completes — Up to $0.6B of adjuster revenue, majority in 2027-2028.

The Company
First Solar makes cadmium-telluride thin-film solar modules in a single segment it calls the Modules Business. Its two shipped products are the Series 6 Plus, a glass laminate about 4 feet by 6 feet, and the Series 7, a larger 4-by-7-foot form factor. The 10-K describes the company as the world's largest thin-film solar module manufacturer and the largest solar module manufacturer in the Western Hemisphere. It reported surpassing 100 GW of cumulative module sales in Q2 2026.
The company is substantially U.S.-based and vertically integrated. It operates manufacturing plants in Perrysburg and Lake Township, Ohio; Trinity, Alabama; and Iberia Parish, Louisiana, with a finishing facility under construction in Gaffney, South Carolina, plus plants in Kulim, Malaysia; Ho Chi Minh City, Vietnam; and Tamil Nadu, India. A next-generation CdTe upgrade, CuRe, is being replicated across the Series 6 and Series 7 fleet, and a perovskite pilot line in Perrysburg targets operational readiness in 1H 2027. Management says it will source supply first from fully integrated U.S. factories, then the South Carolina finishing line, then international facilities.
Business Segments
Competitive Landscape
First Solar competes in a module market where, in management's words, "the vast majority of our competitors are Chinese and tend to play by a different set of rules." Its position rests on a CdTe thin-film technology that does not depend on Chinese crystalline-silicon supply chains, and on a substantially U.S.-based manufacturing footprint. The order book reflects that: 41 of 45 GW of backlog carries some form of domestic-content requirement. The company has enforced TOPCon patents in District Court against JinkoSolar and Canadian Solar, and on 2026-02-24 petitioned the USITC against ten respondents; it said on 2026-09-15 it intends to withdraw the ITC complaint while continuing the District Court suits.
- JinkoSolarSued by First Solar in District Court on 2025-02-25 over TOPCon patents, and a respondent in the USITC petition.
- Canadian SolarSued by First Solar on 2025-05-09 over TOPCon patents, and a respondent in the USITC petition.
- Newly named in the competitor set. Management said a Tesla TOPCon choice would imply infringement and it would enter a commercial conversation; Tesla's own call does not mention First Solar.
- Named competitor; calls itself a Section 232 "poster child" with a domestic polysilicon-to-cell chain and has acquired TOPCon IP it can license in the U.S.
- Hanwha QCellsNamed in filings and a USITC respondent in First Solar's TOPCon petition.
Supply Chain
First Solar turns refined cadmium and tellurium into finished solar modules for utilities and project developers. Its 10-K says several key inputs, including CdTe, tellurium, substrate glass, and manufacturing equipment, are single-sourced or sourced from a limited number of suppliers.
