Immatics (NasdaqCM:IMTX) Valuation Check After Dilutive Follow-On Equity Offering and Sharp One-Day Share Price Drop

Listen to the news

Immatics (NasdaqCM:IMTX) just priced a follow on equity offering, selling 12,500,000 new shares at 10 dollars each to raise about 125 million dollars, a move that directly affects shareholder dilution and funding runway.

See our latest analysis for Immatics.

The sharp 1 day share price return of negative 14.24 percent after the raise comes on the back of a powerful 90 day share price return of 75.82 percent and 1 year total shareholder return of 30.85 percent, suggesting momentum is cooling but the broader rerating remains intact.

If you are weighing biotech risk reward trade offs after Immatics latest move, it is worth exploring other healthcare stocks that might have a different balance of growth and dilution risk.

With shares still trading at a steep discount to analyst targets despite robust revenue growth but persistent losses, investors now face a pivotal question: Is Immatics undervalued after the raise, or already pricing in its future growth?

Price-to-Sales of 12.5x: Is it justified?

Immatics last closed at 10.18 dollars and the stock screens as expensive on a price-to-sales basis compared with both peers and the wider biotech group.

The preferred multiple here is the price-to-sales ratio, which compares the companys market value with its annual revenue. This is a common yardstick for loss making, high growth biotechs where earnings are not yet meaningful.

Immatics trades on a price-to-sales ratio of 12.5 times, above both its direct peer average of 10.3 times and the broader US biotech industry at 12 times. This implies investors are already paying a premium for its pipeline and forecast growth, even though our fair price-to-sales indicator suggests a much lower level of about 1 times as a potential anchor the market could converge toward if sentiment cools.

That premium multiple stands out, not just versus comparable biotech names but also against the estimated fair ratio. It signals a valuation that is materially richer than what fundamentals alone might justify if execution or trial news were to disappoint.

Result: Price-to-Sales of 12.5x (OVERVALUED)

However, setbacks in pivotal trials or slower than expected revenue traction from its TCR pipeline could quickly compress that premium valuation.
