Cogent Biosciences (COGT) Valuation After Positive APEX and SUMMIT Trial Results in Systemic Mastocytosis

Cogent Biosciences (COGT) just delivered another important clinical update, with positive APEX Part 2 results in advanced systemic mastocytosis and full SUMMIT data in nonadvanced disease, reinforcing bezuclastinib as its core value driver.

See our latest analysis for Cogent Biosciences.

Those back to back APEX and SUMMIT wins help explain why Cogent’s 90 day share price return is 230.41% and its 1 year total shareholder return sits at 404.46%, suggesting bullish momentum rather than a one off spike.

If this kind of trial driven move has your attention, it could be worth exploring other innovative names in healthcare stocks to see what else fits your strategy.

With bezuclastinib now boasting three pivotal wins in 2025 and shares already up more than fourfold in a year, the key question is whether Cogent remains mispriced or if the market is already factoring in its next stage of growth.

Price to Book of 30.9x: Is It Justified?

Cogent Biosciences last closed at $39.55, and on a price to book basis the stock screens as richly valued versus both peers and the wider biotech space.

The price to book multiple compares a company’s market value with the net assets on its balance sheet, a common yardstick for pre revenue biotechs where traditional earnings based metrics are not yet meaningful.

In Cogent’s case, investors are paying a substantial premium, with a 30.9x price to book ratio despite the business remaining loss making and generating less than $1 million in revenue. This implies the market is embedding significant expectations for future bezuclastinib driven cash flows long before profitability arrives.

That premium stands out sharply against the US Biotechs industry average of 2.6x and an 8.3x peer group average. This underscores how aggressively the stock is being priced relative to balance sheet value and suggests sentiment has moved well ahead of traditional valuation anchors.

Result: Price to book of 30.9x (OVERVALUED).

However, setbacks in Phase 3 bezuclastinib data or delays across the broader pipeline could quickly challenge today’s rich multiple and momentum-driven narrative.
