Repligen (RGEN) has been under pressure after a weaker February jobs report hit healthcare stocks, even as the company recently reported quarterly and full year 2025 results that showed positive revenue and net income figures.

At a share price of US$119.99, Repligen has seen a 1 day share price return of 4.03% decline, a 30 day share price return of 15.61% decline, and a 1 year total shareholder return of 22.94% decline. This suggests momentum has been fading as investors weigh improving earnings against concerns over margins, scale and the broader pullback in healthcare stocks after the weaker jobs report and recent critical research.

With earnings now back in positive territory and the share price still under pressure, the key question is whether Repligen’s recent weakness has gone too far, creating an opportunity, or whether the market is already correctly pricing in its future growth.

Most Popular Narrative: 37.1% Undervalued

Repligen’s most followed valuation story pegs fair value at $190.89, well above the recent US$119.99 close. This sets up a clear gap for investors to assess.

Strong and sustained order growth across biopharma, CDMO, and capital equipment segments supported by record multi quarter book to bill ratios and a robust funnel positions the company for above market revenue increases as therapy pipelines expand and demand for advanced bioprocessing solutions rises.

Result: Fair Value of $190.89 (UNDERVALUED)

However, that upside story still hinges on biotech funding stabilising and gene therapy demand improving. Both areas have seen recent softness that could undermine those optimistic assumptions.

Another Angle: Rich Multiple Tells A Different Story

On earnings, Repligen looks expensive. The shares trade on a P/E of about 138x, compared with roughly 34x for the US Life Sciences industry and 37x for peers. Our fair ratio sits nearer 26x, and that gap suggests plenty of valuation risk if expectations cool.
