    Mike Polark's questions to Embecta (EMBC) leadership • Q3 2025

    Question

    Mike Polark from Wolfe Research sought further clarification on the impact of geopolitical tensions in China, specifically the trend of preferring local manufacturers. He also asked whether Embecta benefits from syringe demand created by compounding pharmacies selling GLP-1 medications in vials.

    Answer

    CEO Devdatt Kurdikar explained that the updated guidance reflects revised distributor demand in China, driven by the challenging geopolitical environment that may favor local brands and by potential inventory rebalancing. Regarding GLP-1s, Kurdikar stated that while Embecta's syringes could be used with compounded drugs, the company is strategically focused on the much larger, officially indicated opportunity of co-packaging its pen needles with generic GLP-1 therapies, which is expected to be a more significant long-term revenue driver.

    Question

    Mike Polark from Wolfe Research, LLC asked for a quantification of the net inventory destocking headwind included in the full-year guidance and requested the number of active U.S. implanting centers as of June 30.

    Answer

    VP of Investor Relations Ezgi Yagci confirmed that an Inspire IV inventory destocking headwind is factored into the second-half guidance but declined to provide a specific quantification, noting the timing element makes it difficult to pinpoint. She disclosed that the number of active U.S. centers was 'a little over 1,500' at quarter-end, a slight increase from year-end 2024, as the pace of new center openings was intentionally moderated to focus on the Inspire V launch.

    Mike Polark's questions to Beta Bionics (BBNX) leadership • Q2 2025

    Question

    Mike Polark of Wolfe Research, LLC asked about the mix of growth from new versus existing prescribers and questioned the risk of the CMS pay-as-you-go model influencing commercial contracts.

    Answer

    CFO Stephen Feider stated that growth is coming from both deeper penetration in existing accounts and expansion into new territories, but declined to quantify the mix. On the CMS proposal, Feider saw no immediate risk of it spreading to commercial plans. CEO Sean Saint added that the company has proactively insulated itself from this risk by already implementing a pay-as-you-go model in the pharmacy channel, which prepares them for such a market shift.
