    Amazon (AMZN) Stock Could Be 43% Undervalued After AI Tax Break Scrutiny

    Listen to the news

    Amazon.com has delivered a 97.8% share price gain over the past 3 years, and with the stock now around US$246.67, the key issue is whether that climb is still grounded in the cash it can generate for shareholders.

    • That 97.8% 3 year return puts a lot of expectation into Amazon's future cash flows. This makes any gap between price and intrinsic value especially important to understand.
    • Heavy investment in AI infrastructure, data centers and logistics, alongside regulatory and wage pressures described in recent headlines, can reshape both the timing and durability of the cash flows that underpin any Discounted Cash Flow (DCF) estimate.
    • If you'd rather focus on earnings, this one's for you. See what Amazon.com's 19.7x P/E says about the price.

    The issue now is whether Amazon's current share price lines up with what its cash flows support when run through a Discounted Cash Flow (DCF) lens.

    If you want a second reference point while you weigh Amazon.com against its cash flows, a focused stock screen can help you compare it with 88 AI infrastructure stocks.

    Does Amazon.com Look Undervalued on Cash Flow?

    The Discounted Cash Flow (DCF) model here takes Amazon.com’s projected cash generation and pulls it back into today’s dollars to see what those future streams could be worth. Over the last twelve months the group produced about $32.6b of free cash flow, and the model then assumes that cash flow grows rather than shrinks over time.

    Those projections are not smooth. The estimates include a dip in free cash flow in 2027 before climbing to well over $100b a year by 2030. This aligns with a period of heavy AI, data center and logistics spending, followed by a period when those assets are expected to generate more cash. The DCF outcome sits substantially above the current share price of $246.67. This suggests the market is placing a discount on those long term forecasts and the execution risk that comes with them. The letters from Senate Democrats on AI related tax breaks help explain why some investors may still treat the stock cautiously even if the cash flow model points higher than the screen quote.
