Eli Lilly (LLY) Stock Trades At A Discount After Its 439% Run

Simply Wall St·09/27/2026 01:26:04
Listen to the news

Eli Lilly has turned into one of the most closely watched pharmaceutical stocks, with the share price at US$1,183.46 and a very large 5 year gain putting fresh focus on whether the underlying cash flows can carry that kind of valuation. After such a strong stretch, the key issue for you is whether the stock price still matches what the company’s future cash generation can support.

  • The stock has returned 439.4% over 5 years, which puts a lot of weight on the question of how much cash Eli Lilly can realistically produce and sustain over time.
  • Recent FDA approvals, new drug launches and large scale manufacturing investments may support expectations for higher revenue and cash inflows, but they can also reshape the timing and size of future outlays and risks that need to be built into any valuation work.
  • If you'd rather focus on earnings, this one's for you. See what Eli Lilly's 39.5x P/E says about the price.

The issue now is whether today’s price is adequately backed by the cash flows that Eli Lilly is expected to generate over the coming years under a Discounted Cash Flow (DCF) view.

Is Eli Lilly Still Cheap on Cash Flow?

The Discounted Cash Flow (DCF) model here is built on the cash the business can return to shareholders over time. Eli Lilly generated about $13.6b in free cash flow over the last twelve months, and the model assumes those cash flows keep growing from that base rather than flattening out or shrinking. That growth path is reflected in rising projected free cash flows over the next decade, then a slower second stage as the company matures.

On those assumptions, the DCF output suggests Eli Lilly’s intrinsic value sits substantially above the current share price of $1,183.46. The recent FDA approval of Onswik for once weekly insulin use helps explain why analysts are comfortable modelling higher future cash generation, even if the market price has already moved a long way. If you want to see how that gap is quantified, along with the detailed cash flow path and discount rate inputs, you can explore the full model through.
