Bristol Myers Squibb (BMY) Stock May Be 46% Below Fair Value As FDA Approval Lands

Simply Wall St·08/18/2026 11:31:54
Listen to the news

Bristol-Myers Squibb stock has delivered a 40.6% 1 year return, while both its Discounted Cash Flow (DCF) intrinsic value estimate and market multiples currently point to the shares trading at a discount to what the business may be worth.

  • The 40.6% gain over the past year suggests sentiment has improved, yet current valuation signals still indicate the market price may be below intrinsic value.
  • Recent FDA accelerated approval for ZENBEXUS can support expectations for future cash flows, while the revived $6.7b lawsuit linked to delayed drug approvals may weigh on how investors price in legal and execution risk.
  • Bristol-Myers Squibb screens as undervalued on most metrics, with 5 of 6 valuation checks pointing to a cheaper entry point than many peers.

For investors, the debate is whether that apparent discount, including an intrinsic value estimate suggesting the stock may be 45.6% undervalued, still offers enough upside after such a strong 12 month run.

Find out why Bristol-Myers Squibb's 40.6% return over the last year is lagging behind its peers.

Does Bristol-Myers Squibb Look Undervalued on Cash Flow?

The Discounted Cash Flow (DCF) model values Bristol-Myers Squibb by estimating the cash the business may generate for shareholders in the future and discounting it back to today.

Based on this 2 Stage Free Cash Flow to Equity model, Bristol-Myers Squibb is valued using last twelve month free cash flow of about $11.45b and projections that assume broadly stable to modestly declining free cash flows over time. On these inputs, the DCF estimate points to an intrinsic value of about $119 per share. Compared with the current share price, that implies the stock is 45.6% undervalued.

The revived $6.7b lawsuit over delayed drug approvals helps explain why the market may still be pricing Bristol-Myers Squibb below the intrinsic value suggested by its cash flows.

On this DCF view, Bristol-Myers Squibb stock appears undervalued relative to what its projected cash generation supports.

Is Bristol-Myers Squibb a Bargain on Earnings?

P/E is a useful lens for Bristol-Myers Squibb because earnings remain a central focus for investors in large, established pharmaceutical companies. On this measure, the stock trades on a P/E of 14.2x, which is below both the Pharmaceuticals industry average of 16.4x and a wider peer average of 58.5x.

The tailored fair P/E for Bristol-Myers Squibb is 18.2x. This reflects what investors might typically pay given the company’s size, sector, profitability profile and risk factors. The current 14.2x level sits below that fair ratio, which suggests the market is applying a discount to the earnings stream even after the strong 1 year share price move and recent news flow around new therapies and legal proceedings.

On the P/E multiple, Bristol-Myers Squibb stock appears undervalued relative to what investors might usually pay for its earnings profile.

The Bottom Line

The intrinsic value estimate from the Discounted Cash Flow (DCF) model and the earnings multiple both point to Bristol-Myers Squibb screening as undervalued, even after recent news flow and legal headlines. The broad valuation checks look strong and the discount suggests the market is still cautious on future execution, legal outcomes and how the pipeline offsets key patent expiries. For you as an investor, the key question is whether that discount compensates for those risks or whether it reflects a value trap if cash flows and earnings do not evolve as optimists expect.
