Approach 1: T1 Energy Discounted Cash Flow (DCF) Analysis

A Discounted Cash Flow model takes estimates of a company’s future cash flows and discounts them back to today using a required rate of return, to arrive at an estimate of what the business could be worth per share right now.

For T1 Energy, the model used is a 2 Stage Free Cash Flow to Equity approach based on cash flow projections in $. The latest twelve month free cash flow is a loss of $227.78 million. Analyst inputs and Simply Wall St extrapolations then project free cash flow moving through a series of years, reaching $630.44 million in 2035, all discounted back to today using the model’s assumptions.

On this basis, the DCF model estimates an intrinsic value of about $13.90 per share. Compared with the recent share price of $11.50, this implies the stock trades at roughly a 17.3% discount to that valuation. Under these cash flow assumptions, this suggests T1 Energy may be undervalued.

Result: UNDERVALUED

Our Discounted Cash Flow (DCF) analysis suggests T1 Energy is undervalued by 17.3%. Track this in your watchlist or portfolio, or discover 46 more high quality undervalued stocks.

Approach 2: T1 Energy Price vs Sales

For companies where earnings are weak or volatile, the P/S ratio is often a useful way to think about valuation, because it compares the stock price to revenue rather than profit, which can swing with investment cycles and accounting items.

Higher growth expectations or lower perceived risk can justify a higher “normal” P/S ratio, while slower growth or higher risk tends to support a lower one. T1 Energy currently trades on a P/S of 3.65x, compared with the Semiconductor industry average of 9.35x and a peer group average of 5.93x, so the stock sits below both of these broad benchmarks.

Simply Wall St’s Fair Ratio metric suggests a P/S of 5.12x could be reasonable for T1 Energy, based on factors such as its growth profile, profit margins, industry, market cap and risk characteristics. This is more tailored than a simple comparison with peers or the industry because it attempts to align the multiple with the company’s specific fundamentals. With the current 3.65x P/S sitting below the 5.12x Fair Ratio, the stock screens as undervalued on this measure.

Upgrade Your Decision Making: Choose your T1 Energy Narrative

Earlier it was mentioned that there is an even better way to understand valuation, so Narratives are introduced here as your own story for T1 Energy that connects what you think about its business to a simple forecast for revenue, earnings and margins, then into a Fair Value that can be compared with the current price to help inform buy or sell decisions. All of this is within the Simply Wall St Community page, where these Narratives are updated automatically as fresh news or earnings arrive. One investor might build a more cautious T1 Energy Narrative anchored around a Fair Value near US$6.00, while another might lean into a more optimistic story closer to US$15.00, and you can see how each story translates into different numbers rather than just a single target.

For T1 Energy, however, we will make it really easy for you with previews of two leading T1 Energy Narratives:

Fair Value: US$15.00

Recent Price vs Fair Value: trading about 23.3% below this narrative fair value

Revenue Growth Assumption: 68.5% per year

• Views T1 Energy as a potential beneficiary of rising U.S. power demand from AI data centers and onshoring, with its G1 Dallas and G2 Austin facilities supporting the development of an integrated solar supply chain.
• Includes an assumption of a shift from current losses to earnings of US$266.8 million by around 2029, supported by higher margins and monetization of Section 45X tax credits.
• Requires confidence that T1 Energy can execute the G2 Austin build out, maintain policy support and address contract and construction risks without major setbacks.

Fair Value: US$9.10

Recent Price vs Fair Value: trading about 26.4% above this narrative fair value

Revenue Growth Assumption: 24.7% per year

• Frames T1 Energy as heavily exposed to U.S. policy support, complex compliance rules and competitive solar markets, which together could limit long term profitability.
• Builds in revenue and margin improvement to 2029, with earnings of US$172.7 million in the model, but pairs this with a view that the current share price runs ahead of those assumptions.
• Emphasizes funding needs, potential changes to incentives and industry pricing pressure as key reasons why future returns could fall short of more optimistic expectations.

Both narratives use the same company and similar public information but reach different conclusions about what appears reasonable for T1 Energy's fair value. Your job as an investor is to decide which story, if either, aligns best with your own assumptions about policy, capital access and long term demand, then size any position accordingly.
