Most Popular Narrative: 6% Undervalued

With Penumbra’s fair value from the most widely followed narrative now at $306.79 and a share price just under $290, there is a modest gap between where consensus thinks the stock should trade and where it sits today. This close alignment suggests investor expectations are running nearly in lockstep with analyst forecasts, a sign of heightened interest and high stakes for coming earnings and clinical milestones.

The soon-to-be-released STORM-PE randomized trial is poised to provide Level 1 evidence comparing Penumbra's thrombectomy technology to standard anticoagulation for pulmonary embolism. A positive outcome could expand guideline adoption, significantly accelerate procedure volumes, and drive substantial revenue growth by rapidly increasing penetration in a very underpenetrated, large market.
