First Solar
Makes solar panels a different way, as a thin coating on glass instead of silicon wafers, mostly in American factories, for the companies building large solar farms.
The scores
Growth2/4 ↓
Revenue guided at or below last year and backlog fell 5.0 GW in six months. The profit that did grow is a credit.
Business quality3/4 ↑
The only large US maker whose domestic line imports no cell or polysilicon. But Qcells has just built the same position in silicon.
Financial position4/4 →
Cash of $1.688B against $37.6M of debt, capital spending funded from operations, no maturity inside the horizon and no financing need.
Execution record2/4 ↓
A pattern of slippage: revenue guided below last year, the second South Carolina phase pushed to mid-2027, the Asian capacity decision deferred again.
Per share capture4/4 →
Share count up 0.20% in a year, no debt, no convertible, no share-funded deals. Nothing stands between operating value and the holder.
Potential3/4 ↑
Bounded and largely committed: 45.1 GW contracted to 2030, roughly a year of the whole US market. The price upside is expected, not signed.
Risk profile2/4 →
Two policies decide the profit and both are externally controlled: a credit Congress can cut, a floor Commerce can waive. Two customers, a tenth each.
Valuation3/4 ↑
Cheap on reported profit, not on what produces it: 7.4 times guided cash profit is fair for a stream that stops in 2032.
Evidence quality3/4 →
Central claims now rest on the proclamation's own annex and the filings. The first pass read the scope from industry commentary and got it wrong.
The Verdict
We rate First Solar attractive. It makes solar panels as a thin coating on glass, mostly in American factories. The business is solid, but its whole profit is a government manufacturing credit, and the market prices it as a subsidy that will end. What the price leaves out is a new rule setting a minimum price and a tariff on imported panels and cells. First Solar makes most of its panels at home and uses no cells, while American rivals assemble imported ones, so the rule lands on their costs. The price is fair and pays nothing for that. The view hinges on new order prices rising.
The long caseAmerica needs more electricity again and solar is the fastest to build; First Solar makes its panels at home, so new import rules raise its rivals' costs, not its own.
The evidence under this - 9 claims
- The credit is disclosed as $1.6B to one decimal place, so the residual is inside its own rounding: anything from $1.55B to $1.65B leaves operating income between +$47M and -$53M. The sign is uncertain; the order of magnitude is not.
- Operating costs in 2025 included production start-up expense for Louisiana, which a steady-state business would not carry.
- Guided operating costs include $90M to $100M of production start-up expense for South Carolina, and guided gross profit is struck after $115M to $135M of costs for factories deliberately held idle. Adding both back leaves roughly break-even rather than a loss, so this is a company investing through the line rather than one that cannot make money.
- The pairing of the worst gross profit with the largest credit is arithmetic on the stated ranges, not a disclosed combination; management does not say the two ends move together.
- The $8B rests on my own discount rate and a flat-to-2029 credit profile; at 8% it is nearer $9B and at 14% nearer $7.3B, which moves the residual by about a fifth either way.
- The residual is not paying for nothing. It buys 45.1 GW contracted through 2030, $1.688B of net cash, six US plants and a technology no rival runs - the loss before the credit is struck after start-up and idle costs a steady-state business would not carry.
- The credit is earned on modules produced in the US and sold to a third party, which is not identical to modules sold in the US, so the ratio is an approximation of domestic production rather than of domestic sale.
- The balance is imported and now faces the same floor as anyone else's imports. Its contracted book is struck near $0.30 a watt, below the $0.38 floor, so that volume depends on the exemption for contracts fixed before 6 August 2026.
- Cell capacity is being built: Qcells alone is adding 3.3 GW at Cartersville, which roughly doubles the national figure, and the trade body's own dashboard would not open to an automated fetch so this rests on its figures as reported.
- Capacity is not utilisation. A module maker holding cell inventory or sourcing from an allied country pays the floor later rather than never.
- The discount rate and the flat-to-2029 profile are both mine. At 8% the figure is nearer $9B and at 14% nearer $7.3B, so the estimate carries a spread of about a fifth of itself either way.
- The credits are sold to third parties at a discount the company does not disclose, so the cash is less than the credit.
- Congress cut other energy credits in July 2025 and could reach this one before 2032, which would make the estimate an upper bound.
The company
Almost every solar panel starts as silicon, melted, sawn into wafers, made into cells in one plant and assembled in another. First Solar skips all of that: it coats a sheet of glass with a thin film of cadmium telluride, cuts it into cells with a laser and seals it under a second sheet.
Its buyers build large solar farms, and many choose it for the tax credits an American-made panel unlocks: about 41 GW of its 45 GW of contracted orders ask for home-grown content.
The evidence under this - 3 claims
- It does import semi-finished product from Malaysia and Vietnam to feed the South Carolina finishing line, and how that is classified on entry is not established here - if it enters as a module it is covered.
- Glass, steel, copper and the tellurium itself are imported and face other tariff regimes; the claim is only that the polysilicon measure misses them.
- The 15% tariff and the floor apply at entry, so a rival assembling in the US from imported cells pays on the cell, not the module - a smaller base than the module floor implies.
How it makes money
It sells panels by the watt under contracts signed years ahead, and collects a manufacturing credit of roughly 17 cents on each American-made watt it sells. The credit is booked as a lower cost, so it shows up as profit: without it, 2025's $1.597B of operating profit would have been a $3.1M loss.
The evidence under this - 5 claims
The rate is the company's own reading of its eligibility as a vertically integrated producer, and the 10-K says the credit phases down from 2030 and that modifications to the law or its interpretation could change it.
- The credit is disclosed as $1.6B to one decimal place, so the residual is inside its own rounding: anything from $1.55B to $1.65B leaves operating income between +$47M and -$53M. The sign is uncertain; the order of magnitude is not.
- Operating costs in 2025 included production start-up expense for Louisiana, which a steady-state business would not carry.
Where the money comes from, stream by stream
| Stream | Share of sales (FY2025) | How it earns it |
|---|---|---|
| Solar modules, United States | 95.7% | Thin-film panels sold by the watt to utility-scale developers and power producers, mostly under multi-year contracts and mostly made in US plants. |
| Solar modules, India | 3.7% | Panels from the Indian plant sold in rupees to Indian developers. |
| Solar modules, other countries | 0.6% | Panels invoiced in France and elsewhere, a remnant of the European business. |
Who runs it
Mark Widmar has run First Solar since 2016, after five years as its finance chief, and Alexander Bradley has run finance since then. Insiders own about 0.4% of the shares, so the people running it are paid to run it rather than owners of it. Their bonus rides on profit before start-up costs, which the government credit alone clears, then on cost per panel, research, American sales and cash; long-term shares ride on future orders and a new technology, none on the share price.
The evidence under this - 4 claims
The stakes are being sold down on schedule: Widmar adopted a Rule 10b5-1 plan in November 2025 to sell 39,951 shares by 10 November 2026 and Bradley one for 19,646 by 30 September 2026 (S01, Item 9B; and C16).
The threshold is struck after the Section 45X credit, which reduces cost of sales (C03), and 2025 operating income before the credit was about nil (C05), so the gate that funds the pool was met by the credit rather than by the manufacturing margin.
The committee says 2026 awards are weighted more heavily to performance units again, and restricted units do tie realised pay to the share price; shareholder return appears in the proxy only in the required pay-versus-performance table, not as an award metric.
Why it wins, and who could beat it
Why customers come back
Its protection is two rules, not the panel. One is the credit. The other arrives on 4 December: imported modules must sell for at least $0.38 a watt and cells $0.22, plus 15%. That covers First Solar's panel too, but binds only imports, and about 70% of its volume is made in America with no cell step. American silicon assemblers have 69.9 GW of module capacity on about 3 GW of cells, so nearly all pay.
Its two US-listed silicon rivals are each worth under $1B, and both lose money.
The evidence under this - 7 claims
The rate is the company's own reading of its eligibility as a vertically integrated producer, and the 10-K says the credit phases down from 2030 and that modifications to the law or its interpretation could change it.
- The credit is earned on modules produced in the US and sold to a third party, which is not identical to modules sold in the US, so the ratio is an approximation of domestic production rather than of domestic sale.
- The balance is imported and now faces the same floor as anyone else's imports. Its contracted book is struck near $0.30 a watt, below the $0.38 floor, so that volume depends on the exemption for contracts fixed before 6 August 2026.
- It does import semi-finished product from Malaysia and Vietnam to feed the South Carolina finishing line, and how that is classified on entry is not established here - if it enters as a module it is covered.
- Glass, steel, copper and the tellurium itself are imported and face other tariff regimes; the claim is only that the polysilicon measure misses them.
- The 15% tariff and the floor apply at entry, so a rival assembling in the US from imported cells pays on the cell, not the module - a smaller base than the module floor implies.
- Cell capacity is being built: Qcells alone is adding 3.3 GW at Cartersville, which roughly doubles the national figure, and the trade body's own dashboard would not open to an automated fetch so this rests on its figures as reported.
- Capacity is not utilisation. A module maker holding cell inventory or sourcing from an allied country pays the floor later rather than never.
The threat
Qcells has built the first American factory that makes every step of a silicon panel on one site, adding 3.3 GW of cells, so it collects the same credits and pays no cell floor.
Cheaper imported silicon is the other threat; First Solar is pursuing patent suits against those rivals in court.
The evidence under this - 3 claims
- Qcells' total US output is put at 8.6 GW against the roughly 17 GW of US module capacity First Solar projects for 2027, so the rival position is real and roughly half the size.
- The claim rests on the rival's own announcement, which is the party with most reason to overstate readiness; nameplate capacity is not shipped volume.
- Cell capacity is being built: Qcells alone is adding 3.3 GW at Cartersville, which roughly doubles the national figure, and the trade body's own dashboard would not open to an automated fetch so this rests on its figures as reported.
- Capacity is not utilisation. A module maker holding cell inventory or sourcing from an allied country pays the floor later rather than never.
- 2026-09-24editedThe company said on 15 September 2026 that it will withdraw its Section 337 complaint without prejudice and move to terminate the investigation, keeping its district-court TOPCon suits. The claim described a petition still being pursued; it now records both the petition and the withdrawal. The Federal Register shows no termination yet, so the next 10-Q is where it is confirmed.

How big it could get
How big this could get
Developers plan 43.4 GW of large American solar farms in 2026, up 60%. At the $0.38 floor that is about $16.5B of panels a year. First Solar already has 45.1 GW contracted through 2030, roughly one year of the whole market.
The evidence under this - 3 claims
Who has signed
Contracted orders total 45.1 GW worth $13.6B, delivering through 2030 at about $0.30 a watt; Silicon Ranch and NextEra Energy each took a tenth of 2025 sales. None of it captures the new floor: the contracts adjust for tariffs only within a limit the company does not state.

What growth costs
Growing has made First Solar's running costs a smaller slice of each sale, since office and sales costs barely rose as revenue nearly doubled. The real cost of growth is factories: for three years it spent more than a third of its sales building them. And its reported profit comes from the credit, not from this.
The evidence under this - 3 claims
- Over the four quarters to June 2026 the two lines rose back to 9.0 cents, research and development reaching 5.0, so the fall is not one way.
- Production start-up is a separate income-statement line of 1.5 to 2.8 cents a year that the numbers card does not carry; it is what each new factory costs before it ships, and it never fell below 1.5 cents.
The 2025 fall reflects factories finished rather than a cheaper growth model: the second South Carolina phase is still to be built, so the ratio rises again with the next capacity step.
- The credit is disclosed as $1.6B to one decimal place, so the residual is inside its own rounding: anything from $1.55B to $1.65B leaves operating income between +$47M and -$53M. The sign is uncertain; the order of magnitude is not.
- Operating costs in 2025 included production start-up expense for Louisiana, which a steady-state business would not carry.
The last report (30 Jul)
Quarter ended June 2026, filed figures.
The second quarter of 2026 looked excellent, with 57.3 cents of each sales dollar left after production costs. But $88.6M of that was expected refunds of tariffs a court struck down, and the first half's $769.2M of profit came with $359.8M of cash consumed.
The telling figures are orders. Contracted orders shrank for a third quarter running, from 50.1 GW to 45.1 GW, though the 1.9 GW won since the last call fetched about $0.36 a watt, above the $0.30 of the older ones.
What it did to the thesisIt weakened the near-term picture but not the argument. Profit leaned on one-off refunds and orders kept shrinking. Yet the newest orders came in at higher prices, the first sign that the new floor on imported panels may lift what buyers pay, which keeps the view Attractive.
The quarter in detail
Sales growth from the previous quarter, filed figures.
Earnings per share $3.92 against $2.90 expected; $3.92 as filed, with no adjustments.
The evidence under this - 5 claims
- The figure is inclusive of technology adjusters that have not yet been earned, so it is a contracted maximum rather than cash received.
- Management said most of the bookings happened in July, after the quarter closed, so it is a number the quarterly filings do not yet carry.
- India bookings in the same half ran at about $0.20 per watt, so the $0.36 is one market rather than the company's price.
The price, and where we disagree
In short. Fair. The price pays for the US tax credit First Solar earns on each panel it makes, and nothing for the new minimum price on imported panels, which could lift what rivals must charge.
The shares hit $269.70 the day after the floor was announced in August, then gave the whole move back within three weeks. The company's forecast predates the rule, so nothing it has published prices the floor. The first sign comes with the September-quarter results on October 29: the price new orders fetch.
The evidence under this - 4 claims
- The guidance was set on 2026-02-24 and reaffirmed on 2026-07-30, both before the August proclamation, so it prices no part of the measure.
- A securities class action covering the period to 2026-02-24 alleges the company understated how far its tariff response would hurt 2026.
- The figure is inclusive of technology adjusters that have not yet been earned, so it is a contracted maximum rather than cash received.
- Management said most of the bookings happened in July, after the quarter closed, so it is a number the quarterly filings do not yet carry.
- India bookings in the same half ran at about $0.20 per watt, so the $0.36 is one market rather than the company's price.
How we read the multiple
Buyers pay about 13 times a year's profit, against about 19 usually. But most of that profit is a tax credit that shrinks from 2030 and ends in 2032. Counting cash and debt, the company costs about $21B:
- About $8B of that pays for the tax credit still to come.
- That leaves about $12B for the factories, forecast to lose $110M to $425M this year without the credit.
- So the import floor counts for nothing, though imports sold for about 27 cents a watt in August, below the 38-cent floor.
Against its own history. Cheaper than its own usual level for each dollar of profit, and that profit is mostly the credit the market expects to end.
The evidence under this - 6 claims
- The discount rate and the flat-to-2029 profile are both mine. At 8% the figure is nearer $9B and at 14% nearer $7.3B, so the estimate carries a spread of about a fifth of itself either way.
- The credits are sold to third parties at a discount the company does not disclose, so the cash is less than the credit.
- Congress cut other energy credits in July 2025 and could reach this one before 2032, which would make the estimate an upper bound.
- The $8B rests on my own discount rate and a flat-to-2029 credit profile; at 8% it is nearer $9B and at 14% nearer $7.3B, which moves the residual by about a fifth either way.
- The residual is not paying for nothing. It buys 45.1 GW contracted through 2030, $1.688B of net cash, six US plants and a technology no rival runs - the loss before the credit is struck after start-up and idle costs a steady-state business would not carry.
- Guided operating costs include $90M to $100M of production start-up expense for South Carolina, and guided gross profit is struck after $115M to $135M of costs for factories deliberately held idle. Adding both back leaves roughly break-even rather than a loss, so this is a company investing through the line rather than one that cannot make money.
- The pairing of the worst gross profit with the largest credit is arithmetic on the stated ranges, not a disclosed combination; management does not say the two ends move together.
- It is one marketplace's median rather than a customs series, and the buyers on it are not the whole market.
- A floor above the clearing price is a floor importers may respond to by leaving the market rather than by paying it, so the gap overstates what any seller collects.
Priced against its rivals
There is no group to price it against. JinkoSolar and Canadian Solar sell the same panel to the same buyers, but the vendor cannot reconcile JinkoSolar's income statement, and one rival alone is not a group. The price is judged against its own history instead.
Where we disagree with the market
A subsidised commodity maker whose earnings expire with the credit, so the tariff win is a trade; 30 of 74 analysts say hold or sell.
The floor lifts what rivals must charge. First Solar makes most of its panels here, so the rule lands on their costs, not its own.
The easy reading was that thin-film panels are exempt. They are not, and once that proved false the real mechanism was easy to miss: a floor that binds imports, in a country whose silicon assemblers import almost every cell.
The rule is also softer than it looks. An importer that documents its price pays only the gap to the floor, so a rival importing at $0.32 pays $0.06, not $0.38, and contracts signed before 6 August are exempt.
What analysts say, and the evidence
The evidence under this - 6 claims
- The credit is earned on modules produced in the US and sold to a third party, which is not identical to modules sold in the US, so the ratio is an approximation of domestic production rather than of domestic sale.
- The balance is imported and now faces the same floor as anyone else's imports. Its contracted book is struck near $0.30 a watt, below the $0.38 floor, so that volume depends on the exemption for contracts fixed before 6 August 2026.
- Cell capacity is being built: Qcells alone is adding 3.3 GW at Cartersville, which roughly doubles the national figure, and the trade body's own dashboard would not open to an automated fetch so this rests on its figures as reported.
- Capacity is not utilisation. A module maker holding cell inventory or sourcing from an allied country pays the floor later rather than never.
- The top-up structure makes the measure weaker per module than a flat $0.38 would be: a rival importing at $0.32 a watt pays $0.06, not $0.38. It also makes the burden proportional to how cheap the import is, which is the design - the cheapest importer pays the most - so the competitive effect is preserved even though the headline overstates the tariff on any given entry.
- The permanent-prohibition penalty cuts the other way and is unusually severe for a customs certification. Its practical effect is to make the pre-August contract exemption expensive to use aggressively, since the downside of getting it wrong is exclusion from the US market rather than a duty bill - which argues that fewer rivals will lean on the exemption than its existence implies.
- This rests on law-firm readings of the proclamation rather than on the customs guidance that will actually administer it, and the documentation an importer must produce is not established here.
- It cuts both ways: it protects First Solar's own imported volume against a floor above its contracted price, and it equally protects every rival's pre-existing contracts, so it delays the benefit as well as the cost.
What could go wrong, and how we would know
The risks
- The floor may not bite. Importers that document their price pay only the gap to the floor, and contracts signed before 6 August are exempt.
- The credit can be cut. Profit rests on a credit that begins phasing down in 2030 and ends in 2032; Congress could cut it sooner.
- Cells made at home. Qcells added 3.3 GW of American cells. Enough more, and rivals stop paying the cell floor.
- Shrinking contracted orders. They have fallen three quarters running, from 50.1 GW to 45.1 GW.
- A shareholder lawsuit. It alleges the company understated what tariffs would cost it in 2026.

- Operating costs in 2025 included production start-up expense for Louisiana, which a steady-state business would not carry.
- Qcells' total US output is put at 8.6 GW against the roughly 17 GW of US module capacity First Solar projects for 2027, so the rival position is real and roughly half the size.

What we still do not know
- How much the cell floor actually adds to a rival's cost. Nobody has published it, though customs trade data could answer it.
- What the tariff clauses in existing contracts are worth; the company has not said.

What would change our view
- Attractive→NeutralThe market pays for the floor
It needs:
- ○Its value, debt included, rises to about 11 times this year's forecast profit before interest, tax and depreciation: the floor finally priced.about ≈$289.27 today, 40% above the last close
- Attractive→UnattractiveThe floor does not bind
It needs any of:
- ○Waivers, quotas or documented top-ups let imported silicon panels keep selling below the floor.watched as it happens
- ○New American orders settle below $0.30 a watt once the floor is in force.checked at the next results, due by 29 Oct
- ○Congress cuts the manufacturing credit before its 2030 phase-down, removing the $8B the price already pays for.watched as it happens
We would also be wrong if
- American cell factories grow enough that rivals stop paying the imported-cell floor.

- 4 December 2026 Minimum import price and 15% tariff take effect, with customs guidance due before it: How the floor is administered: what documentation importers owe and how widely the pre-August contract exemption is used, which decides how much of rivals' cost it reaches.
- February 2027 Q4 2026 results and the FY2026 10-K: 2026 delivered against $4.9B to $5.2B of revenue and $2.10B to $2.19B of credits, the first 2027 guidance under the floor, and the year-end backlog.

- 2 OctNewsFirst Solar files a new TOPCon patent suit; the case rests elsewhere. View heldFirst Solar sued JA Solar and American Panel Solutions in Delaware for infringing its TOPCon cell patent.
- 24 SepNewsTrade-commission patent case dropped; court suits continue. View heldThe import ban it sought was upside the thesis never counted, and the patent suits against its silicon rivals carry on in court.
- 15 SepThesis reviewThe floor is a top-up, but harder to game. View heldRead in full, the rule charges a documented importer only the gap to the floor, but bars for good any importer whose paperwork proves wrong. The two roughly offset.
- 25 AugThesis writtenAttractive, medium convictionWritten after the shares gave back the whole jump that followed August's import floor, on the reading that its thin-film panel fell outside the rule.
- 25 AugThesis reviewThin-film exemption proved false; the case survives. View heldThe rule covers its panel too. The advantage is that the floor binds imports, and First Solar makes most panels at home with no cells, while American rivals import theirs.
