Approach 1: ATI Discounted Cash Flow (DCF) Analysis

A Discounted Cash Flow, or DCF, model estimates what a company might be worth by projecting its future cash flows and discounting them back to today’s value. It is essentially asking what those future dollars are worth in your hands right now.

For ATI, the model used is a 2 Stage Free Cash Flow to Equity approach, based on cash flows in US$. The latest twelve month free cash flow is about $362.7 million. Analyst and extrapolated projections supplied to the model point to free cash flow of $821.0 million in 2029, with a full set of yearly estimates out to 2035 built into the calculation.

Putting all those discounted cash flows together gives an estimated intrinsic value of US$140.98 per share. Against the recent share price of US$151.70, the DCF implies the stock is about 7.6% above this estimate, which is a relatively small gap and suggests the market price is close to what this model supports.

Result: ABOUT RIGHT

ATI is fairly valued according to our Discounted Cash Flow (DCF), but this can change at a moment's notice. Track the value in your watchlist or portfolio and be alerted on when to act.

Approach 2: ATI Price vs Earnings

For a profitable company, the P/E ratio is a useful quick check because it links what you pay per share to the earnings that support that price. Higher growth expectations or lower perceived risk often justify a higher P/E, while slower growth or higher risk usually call for a lower, more cautious multiple.

ATI currently trades on a P/E of 51.20x. That sits above both the Aerospace & Defense industry average of 36.43x and the peer group average of 42.57x. This suggests the market is currently assigning ATI a richer earnings multiple than many of its sector peers.

Simply Wall St’s Fair Ratio for ATI is 33.16x. This proprietary metric estimates what ATI’s P/E might be given factors such as its earnings growth profile, industry, profit margin, market cap and key risks. Because it blends these company specific inputs, it can often be more tailored than a simple comparison with broad industry or peer averages.

Set against the current P/E of 51.20x, the Fair Ratio of 33.16x indicates that ATI is trading at a higher multiple than this model would typically support.

Result: OVERVALUED

Upgrade Your Decision Making: Choose your ATI Narrative

Earlier it was mentioned that there is an even better way to understand valuation, so Narratives on Simply Wall St let you attach a clear story to your numbers by linking your view on ATI’s future revenue, earnings and margins to a concrete forecast and Fair Value, then comparing that Fair Value with the current price to help you decide if the share price fits your thesis. All of this is available within an easy tool on the Community page that updates automatically when new news or earnings arrive.

For ATI, one investor might build a Narrative around a higher Fair Value of US$191.0 that leans on assumptions such as revenue growth of 9.36% a year, a 14.37% profit margin, a future P/E of 34.59x and a discount rate of 7.68%. Another could anchor on a lower Fair Value of US$113.0 using revenue growth of 5.97%, an 11.95% profit margin, a future P/E of 25.63x and a discount rate of 7.82%. Seeing these side by side helps you decide which story you find more reasonable for ATI at today’s price.

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

Fair Value: US$191.00

Gap to Fair Value: about 20% below this narrative fair value based on the last close.

Revenue Growth Assumption: 9.36% a year

• Analysts in this camp anchor on strong long term demand for ATI’s specialty alloys linked to global air travel, decarbonization needs and major aerospace customers.
• The view leans on higher projected revenue growth, rising profit margins, share buybacks and a lower future P/E than today to support the US$191.00 fair value.
• Key risks include alternative materials gaining share, heavier regulatory and capital spending, concentrated aerospace exposure and global trade frictions.

Fair Value: US$113.00

Gap to Fair Value: about 34% above this narrative fair value based on the last close.

Revenue Growth Assumption: 5.97% a year

• This camp focuses on pressure from substitutes, changing manufacturing methods, supply chain localization and intense competition that could cap ATI’s long run profitability.
• The numbers build in slower revenue growth, more modest margin expansion, a lower future P/E and share count growth to arrive at a US$113.00 fair value.
• Upside risks to this view center on persistent aerospace demand, high value proprietary products, backlog support and ongoing efficiency gains that could keep earnings higher for longer.

Seeing these two ATI Narratives side by side lets you decide which set of assumptions feels closer to how you think earnings, margins and valuation should evolve from here.
