BioMarin Pharmaceutical (BMRN) has quietly staged a double digit rebound over the past month, even though the longer term chart still shows steep drawdowns that left many growth investors underwater.

See our latest analysis for BioMarin Pharmaceutical.

At a share price of $61.15, BioMarin’s sharp 1 day and 1 month share price returns contrast with a still negative year to date move and a three year total shareholder return that remains deeply underwater. This suggests sentiment is improving, but long term holders are only starting to see the pressure ease.

If BioMarin’s rebound has you rethinking the wider sector, this could be a good moment to scan for opportunities across healthcare stocks that match your risk and growth preferences.

With BioMarin trading at a hefty discount to analyst targets despite solid revenue and earnings growth, investors face a key question: is this a mispriced rare disease leader, or is the market already baking in future gains?

Most Popular Narrative: 30.9% Undervalued

Compared to BioMarin Pharmaceutical’s last close at $61.15, the most widely followed narrative sees fair value materially higher, implying substantial upside if its assumptions play out.

Company's operational leverage and disciplined cost management as new products move from R&D to commercial stage combined with efforts to improve patient adherence and maximize market penetration are likely to support margin expansion and drive earnings growth.

Read the complete narrative.

Want to see what powers that upside case? The narrative leans on accelerating earnings, a richer margin profile, and a future earnings multiple usually reserved for sector leaders. Curious which specific growth and profitability bets need to land for that valuation to hold?

Result: Fair Value of $88.48 (UNDERVALUED)

Have a read of the narrative in full and understand what's behind the forecasts.

However, downside risks remain, including intensifying competition around Voxzogo, as well as higher R&D and SG&A spending that could pressure margins and earnings.

Another Angle on Valuation

Even with the 30.9 percent upside implied by the narrative fair value, BioMarin’s 22.6 times earnings multiple sits above both the US Biotechs industry at 20.7 times and peers at 20.4 times. The fair ratio points closer to 24.6 times. However, does paying a premium today leave less margin for error?
