Disc Medicine (IRON) Reports Encouraging RESTORE PV Data, Is The Stock Undervalued?

Simply Wall St·09/17/2026 11:28:10
Listen to the news

Disc Medicine (IRON) is back in focus after new Phase 2 RESTORE-PV data on its antibody DISC-3405 in polycythemia vera reported controlled hematocrit, fewer phlebotomies, and improved patient-reported symptoms.

Despite the positive RESTORE-PV update, Disc Medicine’s share price has slipped over recent weeks. The 7-day share price return is down 10.38% and the 30-day share price return is down 14.34%, while the 1-year total shareholder return of 12.35% suggests longer term holders have still seen gains, even as recent momentum has faded.

Capitalize on the renewed interest in Disc Medicine and compare it with other hematology focused biotechs by scanning our hand picked 16 high quality undiscovered gems now.

Disc Medicine now trades at US$68.57 while analyst targets and intrinsic value estimates sit much higher. Are investors looking at a temporary pullback, or is there a deeper mismatch between price and fair value?

DCF suggests Disc Medicine could be materially undervalued

The SWS DCF model estimates a future cash flow value for Disc Medicine of $228.43 per share compared with the recent $68.57 trading price, which points to a wide valuation gap.

This framework projects the company’s expected future cash flows and then discounts them back to today using a required return, so you get a single present value number instead of a loose range of opinions. It treats the stock as a claim on all those future cash streams rather than just next quarter’s headlines.

For a clinical stage biotech like Disc Medicine, with minimal current revenue and a forecast revenue growth rate of 67.1% per year, this kind of model puts more weight on long dated potential than near term losses. That also means small changes in assumptions around future success rates or timing can move the fair value materially. This helps explain why the model value can sit far above or below the latest share price for long periods.

Look into how the SWS DCF model arrives at its fair value.

Result: DCF fair value of $228.43 (UNDERVALUED)

Still, the story around Disc Medicine can change quickly if clinical timelines slip or if ongoing trials fail to support the current valuation gap.

Price ratios send a more cautious signal

On simple price ratios, Disc Medicine looks less clear cut. The stock trades at a P/B of 4.1x, which is richer than the US Biotechs group at 2.2x, yet below its closer peer average of 7.7x. That mix suggests some optimism is already baked in, even if peers trade on loftier multiples.

For investors, this means the upside hinted at by other models could come with meaningful valuation risk if sentiment cools or trial news disappoints. The fair ratio, which reflects where the P/B could move toward over time, becomes important context. Is the current premium justified by the pipeline and balance sheet, or is it leaning too hard on future success?
