Penumbra (PEN) Q1 2025: U.S. Thrombectomy Grows 25% as CAVT Drives Market Share Gains
Penumbra’s first quarter underscored the accelerating impact of its proprietary CAVT thrombectomy platform, with U.S. revenue surging and gross margin expanding as operating leverage improves. Management’s guidance signals confidence in sustained domestic momentum, even as China headwinds persist and new innovation cycles ramp. Investors should watch for product launches and U.S. commercial execution as key catalysts through 2025.
Summary
- U.S. Thrombectomy Outperformance: Flash 2.0 and CAVT technology drove rapid share gains and volume-led growth.
- Margin Expansion Signals Operating Leverage: Gross margin improved as product mix and manufacturing productivity offset inflation and international drag.
- Innovation Pipeline in Focus: New launches like Ruby XL and Thunderbolt set up further competitive differentiation and revenue drivers.
Performance Analysis
Penumbra delivered 16% revenue growth year-over-year, with the U.S. thrombectomy business leading at 25% growth and now comprising nearly 80% of total sales. The U.S. VTE (venous thromboembolism) franchise, powered by Flash 2.0 and CAVT (computer-assisted vacuum thrombectomy, a proprietary clot removal technology), grew 42% as hospitals and physicians increasingly converted from legacy therapies and competitor devices. Arterial and stroke segments also posted robust gains, with new products like Lightning Bolt 12 and Bolt 6X accelerating adoption, particularly in procedures previously addressed with open surgery.
Gross margin expanded 160 basis points to 66.6%, driven by favorable thrombectomy mix and operational productivity. Operating income more than doubled as disciplined R&D and SG&A spending, aided by the wind-down of the Immersive business, further improved profitability. International revenue declined due to a $6.7 million drop in China, but EMEA and other regions grew, reflecting CAVT traction where reimbursement supports adoption. The balance sheet remains strong with $379 million in cash and no debt, even after initial investment in a Costa Rica facility for future supply chain flexibility.
- Volume-Led Growth Dominates: Most revenue gains stemmed from new patient volume as physicians shifted away from open surgery and competitive devices.
- China Remains a Drag: International results were tempered by China, but excluding China, international thrombectomy rose 18%.
- Operating Efficiency Improves: R&D and SG&A leverage, partly from Immersive exit, supported margin expansion even as commercial team investment continued.
Penumbra’s performance demonstrates the power of a differentiated technology platform and disciplined execution, with U.S. momentum offsetting international volatility and creating a foundation for further innovation-led growth.
Executive Commentary
"Our strong first quarter results underscore Flash 2.0’s durable growth and momentum in VTE, with 2.0’s demonstrated value proposition continuing to drive conversions from anticoagulation, lytics, and other mechanical thrombectomy platforms to CAVT for both PE and DVT."
Adam Elsesser, Chairman and CEO
"We ended the first quarter of 2025 with cash, cash equivalents and marketable securities balance of $378.8 million and no debt, which is an increase of $38.7 million sequentially driven by strong operating profitability and includes our initial capital expenditure investment in Costa Rica of $10.7 million."

Strategic Positioning
1. CAVT Platform Drives Share Gains
CAVT, or computer-assisted vacuum thrombectomy, is Penumbra’s proprietary clot removal technology that continues to rapidly displace both open surgery and competitive mechanical thrombectomy products. Physician word-of-mouth and clinical data are accelerating adoption, particularly in VTE and arterial markets that have historically seen slower shifts from legacy treatments. Management is leveraging this momentum through targeted market access and commercial investments, focusing on converting new accounts and expanding the addressable patient base.
2. Innovation Pipeline and Product Launches
Penumbra’s innovation engine remains a core differentiator, with recent FDA clearance and expedited inventory build for Ruby XL, a larger-diameter peripheral coil for embolization. The late Q1 launch of Red 72 “Silver Label” in neurovascular stroke has already driven strong physician uptake, while the Thunderbolt platform, now under FDA review, promises to further raise the bar for speed and efficacy in clot extraction. The company is also investing in new embolization and access tools to broaden its leadership across vascular interventions.
3. Resilient U.S. Focus Amid International Volatility
With nearly 80% of revenue now U.S.-based, Penumbra is insulated from current international headwinds, particularly in China where macro and reimbursement issues persist. The company’s U.S. manufacturing base and domestic sourcing for most components also reduce tariff and supply chain risk. Strategic investment in a Costa Rica facility will provide optionality to serve global markets more flexibly as conditions evolve.
4. Margin Expansion and Operating Leverage
Margin expansion is being driven by favorable product mix, operational productivity, and disciplined cost management, including the wind-down of the Immersive business. Management reiterated its goal of exceeding 70% gross margin by end of 2026, with sequential improvements expected in the second half of 2025 following a temporary Q2 dip tied to Ruby XL launch costs.
5. Commercial Execution and Market Access Initiatives
Penumbra’s commercial strategy is increasingly sophisticated, leveraging health economic data, targeted market access programs, and a focused salesforce to drive adoption. Early evidence from scientific meetings and physician feedback suggests that these efforts are gaining traction, particularly as hospitals seek improved patient outcomes and reduced length of stay.
Key Considerations
This quarter’s results highlight Penumbra’s ability to drive volume-led growth, expand margins, and invest in innovation while navigating international headwinds. The company’s U.S.-centric revenue mix, robust balance sheet, and pipeline of new product launches position it well for continued outperformance.
Key Considerations:
- Technology Adoption Wave: CAVT and Flash 2.0 are catalyzing rapid conversion from legacy therapies, driving new patient volume and market share gains.
- Innovation as a Growth Engine: Ruby XL and Thunderbolt launches are set to expand Penumbra’s addressable market and reinforce competitive differentiation.
- Margin Tailwinds from Product Mix: High-margin thrombectomy products and operational efficiency are supporting gross and operating margin expansion.
- International Diversification Remains a Challenge: China macro headwinds persist, though EMEA and other regions are showing early signs of CAVT traction where reimbursement allows.
- Commercial Team Investment: Strategic hiring and market access initiatives are designed to sustain growth and deepen penetration, especially in underpenetrated U.S. arterial and embolization markets.
Risks
Penumbra faces ongoing risks from international market volatility, particularly in China, where macroeconomic and reimbursement challenges are likely to persist through at least Q2. Product launch execution and regulatory timing, especially for Thunderbolt, will be critical to maintaining momentum. Competitive responses, including price increases by peers, could pressure market share or margin if adoption waves slow or hospitals shift procurement strategies.
