Question · Q3 2025

Daniel Clark asked what factors would drive international CAG recurring revenue growth from its current 13% (days-adjusted) to the higher end of the 15%-16% growth potential.

Answer

Jay Mazelsky, President and CEO, explained that achieving 15-16% growth involves continued Salesforce expansions (disciplined, market-ready, product-market fit), specific products like ProSite One, building out the global reference lab network for next-day performance, and ensuring strong in-country customer support ahead of commercial investment.
