Syndax Pharmaceuticals (SNDX) Stock May Be Fully Priced After Trial Setback

Listen to the news

Syndax Pharmaceuticals has seen its share price come under pressure this year, and the latest clinical setback has only sharpened the question of what investors are really paying for in terms of sales. With sentiment shaken, the key issue is whether the current market value lines up with what the business actually generates on the top line.

  • Year to date, Syndax Pharmaceuticals stock has fallen 35.9%, which puts fresh focus on how much investors are now paying for each dollar of the company’s sales.
  • The failure of axatilimab in the Phase 2 IPF trial removes one potential future revenue stream, which can shift how investors think about the durability and scale of sales from the rest of the pipeline.
  • There is a second opinion on Syndax Pharmaceuticals worth weighing. See what analysts think Syndax Pharmaceuticals's shares could be worth.

The issue now is whether Syndax Pharmaceuticals' current share price is justified by its sales when set against the Fair Ratio benchmark.

Has Syndax Pharmaceuticals Run Too Far on Sales?

P/S is usually a cleaner yardstick for a biotech like Syndax Pharmaceuticals where earnings and free cash flow are still deep in the red. On this measure, the stock trades on a P/S of 4.8x, which is below the broader biotech industry average of 11.1x and also below the peer group average of 22.4x for similar companies.

The Fair Ratio framework, which looks at Syndax Pharmaceuticals' growth assumptions, margins, size and risk profile, points to a lower sales multiple than where the shares currently change hands. Because the latest axatilimab IPF trial failure removes one potential future revenue stream, the current P/S can still leave limited room for disappointment if the remaining pipeline underdelivers. For anyone weighing the stock, the gap between the live P/S and the Fair Ratio benchmark is the key question to test. Explore the numbers behind Syndax Pharmaceuticals's P/S valuation.
