Gilead (GILD) Stock Stays Cheap After A 143% Five Year Run

Simply Wall St·08/29/2026 23:30:26
Listen to the news

Gilead Sciences stock has delivered very strong gains over the past few years, yet current valuation checks still suggest the shares screen as inexpensive on several metrics. The question for investors is how that strong track record and the latest product approvals align with a profile that continues to lean cheap.

  • Over 5 years the stock has returned about 143%, which puts recent moves in the context of a long, powerful run that investors now need to judge against today’s pricing.
  • The recent approvals for Bixlenvo in HIV and the expanded European role for Trodelvy can support expectations for future cash flows. Any setbacks in clinical data, safety perceptions or uptake for these therapies may weigh on what investors are willing to pay.
  • Gilead Sciences currently earns a high value score, and 5 out of 6 checks point to a stock that looks undervalued on the broader set of valuation measures.

The issue now is whether Gilead Sciences shares still offer enough valuation appeal after such a strong multi year performance.

Spot 44 high quality undervalued stocks that share Gilead Sciences' mix of strong multi year returns and a high value score, while they still screen as inexpensive on key fundamentals.

Is Gilead Sciences Still Cheap on Sales?

P/S is often a useful reference point for a company like Gilead Sciences where revenue and cash flow are key focus areas for investors. It provides a straightforward way to compare what the market pays for each dollar of sales against other biotechs.

Gilead Sciences currently trades on a P/S of 5.9x. This is below the biotech industry average of 13.2x and below the peer average of 7.3x. On Simply Wall St’s fair multiple framework, which looks at factors such as growth, margins, size and risk, a P/S of 10.0x would be more in line with Gilead Sciences. That fair ratio is comfortably above the current level, which indicates a discount on this metric.

Despite the recent approvals for Bixlenvo and the expanded role for Trodelvy in Europe, the stock still trades below what this model suggests would be a reasonable P/S multiple.

On the P/S multiple, Gilead Sciences stock appears undervalued compared with both its fair ratio and sector benchmarks.

The Bottom Line

For Gilead Sciences, the valuation story still leans on a market multiple that screens as undervalued relative to peers and the tailored fair ratio. The high value score lines up with that signal and suggests the current price already bakes in a fair amount of caution on execution and pricing risk. From here, the key question is whether uptake and pricing for the newer therapies are strong enough to keep supporting that discount, or whether the current level already reflects the right balance between the pipeline opportunity and those risks.
