Disc Medicine (IRON) has attracted investors’ attention after submitting a New Drug Application for bitopertin aimed at accelerated FDA review, alongside Phase 2 results for DISC-0974 that suggest broader use with existing JAK inhibitor therapies.

See our latest analysis for Disc Medicine.

The share price has moved to $80.94 after a 4.63% 1 day share price return. However, the 30 day share price return of a 12.25% decline contrasts with a 14.40% 90 day share price return and a very large 3 year total shareholder return of about 4x. This pattern suggests that momentum has been choppy rather than one directional as investors reassess growth prospects and pipeline risk after the bitopertin NDA and DISC-0974 data.

If Disc Medicine’s update has you looking across the sector, this is a useful moment to scan other healthcare stocks that could fit a similar high impact thesis.

With revenue still at US$0 and a net loss of US$181.11 million, alongside a very large 3-year return and a price well below some analyst targets, you have to ask: is IRON mispriced or already reflecting future growth?

Price to Book of 5.3x: Is it justified?

At a last close of US$80.94, Disc Medicine trades on a P/B of 5.3x, which screens as expensive against the broader US biotech peer group.

P/B compares the market value of the company with its net assets on the balance sheet. It is often used for early stage or loss making biopharma names where earnings are not yet meaningful. For a business with US$0 in revenue and a net loss of US$181.11 million, a higher P/B usually reflects investor willingness to pay a premium for the pipeline and potential future cash flow rather than current fundamentals.

What stands out is that IRON is described as good value when compared with a peer average P/B of 6.2x, yet expensive against the wider US Biotechs industry average of 2.7x. So, within its closer peer set the valuation sits at a discount, while across the industry it carries a premium that implies the market is assigning relatively high expectations to Disc Medicine’s hematology pipeline and forecast 55.5% annual revenue growth.

Result: Price-to-book of 5.3x (ABOUT RIGHT)

However, there are clear pressure points, including zero revenue alongside a US$181.11 million loss and heavy reliance on successful outcomes from multiple early stage hematology programs.

Another View: Our DCF Model Paints A Very Different Picture

While the 5.3x P/B suggests Disc Medicine is priced richly against the broader biotech group, our DCF model reaches a very different conclusion. With estimated fair value at US$586.29 versus a share price of US$80.94, the model flags a very large potential undervaluation. This raises the question: which signal do you trust more?
