Merus (MRUS): Reassessing Valuation After a 120% Year-to-Date Rally and Strong Multi-Year Returns

Merus (MRUS) has quietly turned into one of the stronger biotech performers this year, with the stock up more than 120% year to date as investors reprice its antibody pipeline potential.

See our latest analysis for Merus.

That kind of rerating has not come out of nowhere, with Merus enjoying a powerful 90 day share price return of 42.16% and a standout three year total shareholder return of 597.77%. This suggests momentum is still firmly building around its pipeline story.

If Merus has caught your eye, this is also a good moment to see what else is working in healthcare by scanning healthcare stocks for other potential ideas.

Yet with the shares now hovering around analyst targets after a stunning multi year run, investors must ask whether Merus is still trading below its true pipeline potential or if markets have already priced in the next leg of growth.

Price to Book of 9.5x, is it justified?

At a last close of $96.92, Merus trades on a rich valuation that looks stretched against many biotech peers, but not extreme within its closest group.

The preferred multiple here is the price to book ratio, which compares the company’s market value to its net assets on the balance sheet. For early stage, loss making biotechs, this metric often captures how intensely investors are pricing in future pipeline success rather than current earnings power.

Merus changes hands at 9.5 times book value, which is markedly more expensive than the broader US biotech industry average of 2.7 times. This signals that investors are assigning a substantial premium for its anticipated revenue growth and bispecific antibody pipeline. However, that 9.5 times multiple actually screens as good value relative to a tighter peer set, where the average price to book is an even richer 15.7 times. This suggests Merus is not the priciest way to gain exposure to this corner of the sector.

However, significant clinical setbacks or partnership disruptions could quickly erode confidence in the Merus pipeline premium and pressure its richly valued shares.
