Matthew O'Brien's questions to Integer Holdings (ITGR) leadership

Question · Q3 2025

Matthew O'Brien asked about the approximate $70 million reduction in the CMD outlook for next year, questioning if it was evenly split between the two EP products and if these were emerging customers outside the top three. He further clarified if the EP and neuromodulation impacts were from emerging customers and if the neuromodulation impact was from an existing, sizable customer seeing less adoption.

Answer

Payman Khales, President and CEO-elect, clarified that the approximate $70 million reduction is for three products (two EP, one neuromodulation), not just two EP products. He confirmed these are emerging customers, part of a group of 10 customers with products in the market or launch phases. Khales stated that Integer's EP business is broad, serving both large OEMs and others, and could not be more specific. For neuromodulation, he confirmed that one customer, which had sizable growth in 2025, is now seeing less market adoption, leading to a significant decline in 2026.

Question · Q3 2025

Matthew O'Brien sought to confirm the estimated $70 million reduction to the CMD outlook for 2026 across three products. He also asked for clarification on whether 'emerging customers' are those outside Integer's top three largest clients and if the neuromodulation impact involves a sizable customer experiencing less adoption.

Answer

Payman Khales, President and CEO-elect, confirmed the estimated reduction was 'in the ballpark' for three products (two EP, one neuromodulation). He clarified that 'emerging customers' are newer clients with new products and therapies, not necessarily the largest OEMs. He also confirmed that the neuromodulation customer had significant growth in 2025 but expects a sizable decline in 2026 due to slower market adoption.

Matthew O'Brien's questions to KESTRA MEDICAL TECHNOLOGIES (KMTS) leadership

Question · Q1 2026

Matthew O'Brien inquired about the drivers behind the strong sequential and year-over-year prescription growth in the quarter, asking about the current market share and the company's target for market share by the end of the fiscal year. He also asked whether new sales representatives primarily focus on converting existing accounts from competitors or on expanding the overall market.

Answer

President and CEO Brian Webster attributed prescription growth to improving metrics for fully onboarded reps and new reps successfully ramping up productivity. He estimated current market share at around 12%. Webster explained that new reps are directed to high-prescribing accounts first, leveraging pre-existing relationships where applicable, while established reps focus on further penetrating existing accounts and opening new ones to expand the market. He also noted that the competitor's recent study on sudden cardiac death risk would help expand the overall WCD market.

Matthew O'Brien asked about the drivers behind the strong sequential prescription growth, Kestra Medical Technologies' current annualization of cases, and the expected percentage of all WCD prescriptions for ASSURE by year-end.

Answer

Brian Webster (President and CEO) attributed prescription growth to improving metrics for fully productive reps and successful onboarding of new reps. He noted that new reps initially target high prescribers, while existing reps focus on deeper penetration and opening new accounts to expand the market. He also viewed the competitor's large German WCD study as beneficial for overall market expansion, shining a light on the ongoing need for WCDs.
