Mesoblast (ASX:MSB) Valuation in Focus After Ryoncil Secures U.S. Reimbursement Milestone

Mesoblast (ASX:MSB) shares have drawn attention after the company announced that its Ryoncil therapy received a permanent J-Code from U.S. Centers for Medicare & Medicaid Services, effective October 1. This update simplifies reimbursement and billing for providers.

Mesoblast’s latest breakthrough with Ryoncil arrives as investor optimism has been building steadily. After lagging earlier in the year, the share price has surged 75% in the past three months, and the one-year total shareholder return now stands at an impressive 99%. These gains suggest momentum is returning, supported by regulatory milestones and hopes for broader adoption.

Price-to-Book Ratio of 4x: Is it justified?

Mesoblast's price-to-book ratio stands at 4x, noticeably lower than both the Australian Biotechs industry average of 4.9x and the peer average of 4.4x. This suggests the shares offer relative value at the last close of A$2.89.

The price-to-book ratio tells investors how much they are paying for each dollar of net assets the company holds. In the biotech sector, where future profits are often speculative, the price-to-book can indicate market confidence in a company’s innovation pipeline or highlight a disconnect between tangible assets and market expectations.

With Mesoblast trading below its peer group and sector on this ratio, the market could be underestimating the company’s growth outlook or built-in optionality from its therapy approvals. If the broader market moves closer to its fair ratio, there may be further upside ahead.

Result: Price-to-Book Ratio of 4x (UNDERVALUED)

However, investors should note that Mesoblast’s consistent net losses and reliance on breakthrough approvals could limit share price gains if clinical or regulatory setbacks occur.
