What The Price Assumes (Inversion)

The assumption today's price embeds, recovered by inverting the valuation.

The operating-margin figure is value-band context at year 8: derived from the framework's value band, a separate calculation — not part of the priced-in solve.

Solve inputs: computed at a 10.3% cost of capital with 4% terminal growth over a 5-year stage.

How unusual the bet is: within-range (limited comparison data)

Valuation X-Ray

The price is supported by asset-based and earnings-power and relative-multiple and growth-DCF value. A value/asset-supported name, not a pure growth bet.

How the valuation models price the stock relative to the market price. Price/FV above 1.0 means the market pays more than that lens defends (expensive); at or below 1.0 the lens can defend the price.

Families that justify the price: Asset, Earnings, Relative, Growth

The models below discount at their own flat-beta convention rates (cost of equity 9.3%, WACC 9.2%); the inversion above states its own rate.

Economic-Unit Decomposition (Sum Of The Parts)

Only one reportable economic unit is present in the current topology source. Consolidated operating lenses remain available, but there is no multi-unit decomposition.

No total common-equity value is stated. One or more material units lack a supported unit value. The displayed values are an indicative subtotal; consolidated debt and cash cannot be applied to a fraction of the company.

Solvency

Bullet Takeaways

• First Solar sells almost nothing into the spot market: as of March 31, 2026 it "had entered into contracts with customers for the future sale of 47.9 GW of solar modules", worth 14.4 billion dollars of revenue it expects to book through 2030.
• Two buyers each took a tenth or more of module sales in 2025 and the industry added roughly 105 GW of new manufacturing capacity that year, most of it in China, so both the order book and the selling environment are more concentrated and more crowded than the headline growth suggests.
• Second-quarter results are scheduled for July 30, 2026, and the line to watch is that contracted order book, which slipped from 50.1 GW at the close of December to 47.9 GW three months later.

Bull Case

Four different families of valuation method get pointed at this company, and the striking thing is how little daylight separates them from the quote on the screen. Book value plus profitability lands modestly under where the shares trade. So does the approach that capitalises today's earnings and credits no growth at all. Comparisons against other listed solar companies and the discounted cash-flow builds both land above. A module manufacturer is supposed to be a story stock, priced on a decarbonisation narrative and defended with adjectives. This one is being valued roughly the way you would value a profitable machine shop.

The reason sits in the factory. Nearly every competitor builds modules from crystalline silicon wafers bought through a multi-tier supply chain that runs largely through China, which means their cost structure is somebody else's cost structure plus a margin. First Solar makes thin-film cadmium telluride modules on its own lines, start to finish, and the annual report is unsentimental about what that is for: "Our differentiated technology, integrated manufacturing process, and tightly controlled supply chain help limit the risks associated with outsourcing". Keeping that process ahead has taken more than two billion dollars of cumulative research spending across two decades by the company's own count, and the work continues; the same filing describes "the construction of a dedicated perovskite development line at our Ohio facility".

What the process buys commercially is an order book most manufacturers would not recognise. The contracted 47.9 GW carries an aggregate value of 14.4 billion dollars and runs through 2030, close to three years of current sales already committed under contract before a single new customer conversation happens. And it converts. Operating income over the four quarters through March 2026 came to 1.72 billion dollars on 5.42 billion dollars of revenue, which is close to a third of every sales dollar in an industry where several listed competitors cannot earn a positive one.

The heavy building is largely behind it. Additions to plant and equipment ran 1.53 billion dollars in 2024, 869.9 million in 2025, and 118.5 million in the first quarter of 2026 against 206.0 million in the same quarter a year earlier. The same operating profit is worth considerably more to an owner when the factories it funds are finished than when they are half-built, and the business generated far more from operations in fiscal 2025 than it put into plant that year. That gap is the part of the story that shows up late.

There is one asset here that no multiple picks up. First Solar owns United States patents covering TOPCon, the crystalline-silicon architecture its competitors have been converting to, and it is enforcing them. In April 2025 "Mundra, whose parent corporation is Adani Green Technology Limited, filed a lawsuit in the United States District Court for the District of Delaware seeking a judgment declaring that it has not infringed two of our U.S. TOPCon patents", and the company answered with a suit of its own the following month. A thin-film manufacturer collecting royalties on silicon technology it does not itself use is an unusual position to hold.

None of this makes the company immune to what modules sell for, and the bear is right that the selling environment is worsening rather than improving. The bull answer is that the cost position, the contracted book and the balance sheet all exist precisely to survive that, and the valuation is not asking for more than survival.

Bear Case

Begin with what management does with the money, because that is usually the honest statement of what management believes. First Solar closed March holding roughly 1.96 billion dollars more in liquid assets than it owes in borrowings. None of it comes back to owners. There is no dividend. The share count has not fallen; it has drifted up about 0.3% a year since early 2022, which is what stock compensation looks like when nothing is being retired against it. Every dollar the business earns is recycled into manufacturing capacity.

Into what, is the question. The 10-K states the scale of the industry build-out plainly: "we estimate that in 2025 approximately 105 GW of capacity was added by solar module manufacturers, primarily in China". That is more than double this company's entire contracted order book, added by other people in a single year. And the filing draws its own conclusion: "We believe the solar industry may from time to time experience periods of structural imbalance between supply and demand, and that excess capacity will continue to put pressure on pricing". Building into that is a defensible strategy for the low-cost producer. It is not a strategy that tolerates being wrong about who the low-cost producer is.

The order book is also narrower than its size implies. During 2025 "Silicon Ranch Corporation and NextEra Energy each accounted for 10% or more of our modules business net sales", and the company "sold the majority of our solar modules to customers with projects in the United States", which shows up in the revenue mix as the United States at 96% of the total. Two large buyers, one policy regime. Contracts have failed before: terminations by two customers pulled 61.0 million dollars of previously received advance payments into revenue and cut the contracted volume accordingly. And the book is now shrinking rather than growing, from 50.1 GW at the end of December to 47.9 GW at the end of March.

There is a product question underneath all of that. The annual filing warns that "the identified manufacturing issues affecting certain Series 7 modules may adversely impact the average selling prices of our modules or the carrying value of our inventories", and that warranty claims from customers may rise with them. For a company whose entire commercial argument is that its modules are the reliable ones, a quality issue is not an ordinary cost line. It is an attack on the reason the premium exists.

What makes this bear case awkward to state is that it is not an overvaluation argument, and dressing it as one would be dishonest. The quote embeds something like 9.7% a year of operating-profit growth held for a five-year stretch, which sits comfortably inside what this company has recently delivered. The requirement is not the problem. The base it is applied to might be: policy-supported domestic demand, a content premium that exists because Washington decided it should, and a cost advantage that assumes the competition does not close the gap. Shrink that base by a third and the modest growth requirement stops being modest, because the thing being grown got smaller first.

Valuation

Take the quote as given and ask what it assumes. Today's level implies operating profit compounds at roughly 9.7% a year and keeps it up over a five-year stretch, on the kind of economics the business has actually been earning rather than an improved version of them. Measured against its own recent record, that pace is unremarkable. The demand is duration, not speed.

The methods behind that arithmetic disagree with each other, and the shape of the disagreement is the useful part. Book value plus profitability, and the version that capitalises current earnings while crediting no growth whatsoever, both land modestly under where the shares trade. Comparisons against other listed solar companies, and the cash-flow builds, land well above. That is the signature of a value-supported name rather than a growth bet: the optimistic approaches are the ones calling it cheap, and the conservative ones are not calling it expensive by much. Nothing in the set requires a heroic assumption to reach today's number, which is a rarer configuration than it sounds.

What has to be true is a margin. Over the four quarters through March 2026 the company earned 1.72 billion dollars of operating profit on 5.42 billion dollars of revenue, close to a third of every sales dollar. The priced-in assumption does not require that to improve. It requires it to hold, which is a different question and a harder one, because the contracted book that supports it converts on a schedule the company has already published: the 47.9 GW under contract is revenue "we expect to recognize as revenue through 2030 as we transfer control of the modules to the customers". Visibility is real here in a way it is not for most manufacturers, and it runs out.

The cohort makes the point sharper. NXT, which sells trackers rather than modules, runs an operating margin near 19.6% on 3.56 billion dollars of trailing revenue. ENPH, in microinverters, earns 6.9% at the operating line. SEDG loses money there outright. First Solar earning close to a third of revenue as operating profit is why the peer-multiple comparisons land above the quote rather than below it: the group it is measured against is markedly less profitable than it is, and applying that group's multiple to this company's earnings produces a number the market has not paid.

The balance sheet does not carry much of the argument, and that is itself informative. Liquid assets exceed total borrowings by roughly 1.96 billion dollars, the interest bill is trivial against operating profit, and operations fund the capital programme rather than the other way round. That does not create value; it buys the right to be wrong about a year of module demand without the question becoming existential. In a manufacturing industry carrying structural oversupply, that is the more relevant kind of protection, and it is the reason a cyclical earnings base can be underwritten at all.

Catalysts

Second-quarter results are scheduled for July 30, 2026. The first quarter was reported on April 30, 2026, so the coming print is the first full read on how the business moved through the middle of the year.

The contracted order book is the number that matters most in it. It stood at 50.1 GW covering 15.0 billion dollars of future module sales on December 31, 2025, and 47.9 GW covering 14.4 billion dollars three months later. Value per watt barely moved between the two, so the change is volume rather than discounting: contracts converted into shipments faster than new ones were signed. One quarter of that is seasonality. Two quarters of it is a demand signal.

Capital spending runs alongside as the second thread. Additions to plant and equipment were 869.9 million dollars in 2025 against 1.53 billion in 2024, and 118.5 million in the first quarter of 2026 against 206.0 million a year earlier, the profile of a build-out that is finishing rather than starting. Separately, the patent docket stays live: Mundra Solar, a subsidiary of Adani Green, filed for a declaratory judgment of non-infringement on two of the company's United States TOPCon patents in Delaware on April 15, 2025, and First Solar filed its own suit on May 9, 2025. The outcome is not visible from here. The asymmetry is: a favourable ruling monetises technology the company does not use, and an unfavourable one costs it nothing it currently earns.

Methodology Note

• Priced-in inversion: the valuation is inverted on the current price to recover the operating-income growth, duration, and steady-state margin the price embeds (ROE for financials, FFO growth for REITs).
• Valuation x-ray: the valuation models, grouped into four families (asset, earnings, relative, growth). Each model is expressed as a price/FV ratio (distance from price), not a point fair-value estimate. The spread across families is the disagreement.
• Economic-unit decomposition (SOTP): each disclosed business unit is assigned its native valuation basis before any multiple is applied. Operating units are valued on enterprise value; funded financial units are valued on their own common equity, because their borrowings fund earning assets rather than levering the parent. A company total is stated only once every material unit carries a supported value and the parent capital bridge reconciles.
