    What went well

    • The company's proprietary products are driving strong growth across multiple segments and regions. Their SynerGraft pulmonary valve has no competitors, and the On-X valve is the market-leading mechanical valve with data showing an 87% reduction in major bleeding. This is leading to increased market share, with a 30% global share in mechanical valves and over 50% in the U.S., indicating significant room for growth internationally.
    • Positive clinical data reinforces the efficacy of their key products, supporting further adoption. The 5-year post-approval study of the On-X valve shows a significant reduction in major bleeding without increasing thromboembolism. Surgeons are seeing this data and questioning why they would use any other valve.
    • Operational improvements and increased supply are contributing to strong revenue growth. The company has had no supply problems for over 1.5 years, and improvements have increased yields. The Ross procedure is growing extremely fast, and as the market share leader, they are capitalizing on this growth, expecting double-digit growth in their tissue business for the year.

    What went wrong

    • The company reported negative free cash flow of $9.1 million in Q1 2024, and management is not committing to positive free cash flow in every quarter, which raises concerns about cash generation and liquidity.
    • Despite strong Q1 performance, management is not raising its full-year adjusted EBITDA guidance, suggesting potential pressures on future earnings due to expected catch-up in R&D spending or other uncertainties.
    • Gross margins are expected to remain flat year-over-year despite significant revenue growth, indicating limited operating leverage and potential cost pressures affecting profitability.

    Q&A Summary

    1. On-X Valve Market Share and Potential
      Q: How much market share can On-X gain, including bioprosthetic valves?
      A: On-X holds about 30% global share in the mechanical valve market, exceeding 50% in the U.S.. With significant room for international growth, the company is aggressively targeting the mechanical segment. Recent data may open opportunities in the bioprosthetic market for patients under 65, but management is currently focused on mechanical valves.

    2. Pricing Power of On-X Valve
      Q: Can you increase On-X valve pricing given recent data?
      A: Management believes On-X's superior clinical data positions it between mechanical and tissue valves, granting potential for price increases. They consider it the best mechanical valve and intend to exploit this pricing power, though specifics were not disclosed.

    3. Tissue Business Growth and Sustainability
      Q: Can tissue business sustain double-digit growth beyond this year?
      A: The tissue business benefits from the rapid growth of the Ross procedure, operational improvements increasing yields, and price increases annualized in Q1. Management feels strong about achieving double-digit growth this year and sees ongoing opportunities, though supply constraints may impact long-term growth.

    4. Aortic Business Growth Drivers
      Q: What drove the strong growth in the aortic business?
      A: The aortic stent graft business grew 23% GAAP and 19% constant currency. Growth is driven by proprietary products like AMDS, which showed a 72% reduction in mortality in recent U.S. trials. Additional technologies like the frozen elephant trunk and branched stent grafts are also contributing to rapid growth.

    5. SG&A Leverage and Expenses
      Q: How sustainable is the SG&A leverage achieved this quarter?
      A: Management sees SG&A leverage as a significant opportunity going forward. While a 500 basis point improvement may not occur every quarter, strong revenue growth enhances model leverage. They expect SG&A expenses to remain consistent with Q4 levels, driving solid leverage year-over-year.

    6. Free Cash Flow Outlook
      Q: What is the free cash flow outlook for the rest of the year?
      A: Cash flow can vary quarterly, but management expects positive free cash flow for the full year, likely stronger in the second half due to heavier cash outlays in the first half.

    7. NEXUS Trial and Acquisition Option
      Q: What's the update on NEXUS and potential acquisition?
      A: The NEXUS trial has enrolled 44 out of 60 patients, showing strong results. Completion is expected in the second half. Management sees NEXUS as a meaningful opportunity to treat chronic dissections or aneurysms of the arch with a catheter and is closely monitoring the trial due to their investment and acquisition option.

    8. Maintaining Guidance Despite Strong Q1
      Q: Why maintain guidance despite strong Q1 performance?
      A: It's early in the year, and part of the strong start was due to timing of R&D spending, which will occur later. Management prefers to wait and observe the year's progression before adjusting guidance.

    9. Gross Margin Expectations
      Q: How do you see gross margins, especially for tissue products?
      A: Overall gross margins are expected to remain relatively flat year-over-year. The SynerGraft pulmonary valves have margins above the company average, and their growth serves as a tailwind for margins.

    10. NEO's Growth in EMEA
      Q: Can you discuss NEO's performance and expansion?
      A: NEO is experiencing rapid growth through expansion into Asia, Latin America, and Europe. As a proprietary technology with a unique stent system, it offers better outcomes than competitors. The company is aggressively pursuing this opportunity, though NEO is not yet approved in the U.S. or Japan.
