Question · Q3 2025
Dave Windley inquired about the demand and growth trajectory for Nelson Labs' core lab testing business, and asked for insights into the Q4 sequential progression, including revenue growth and margin pullback, particularly regarding Nordion's lumpiness.
Answer
Chairman and CEO Michael Petras noted core lab testing was doing well with routine volumes picking up, and growth in areas like extractable leachable testing. He explained that the Q4 revenue and margin dynamics were influenced by Nelson Labs' expert advisory services and Nordion's expected significant year-over-year decline due to timing, despite Nordion's full-year performance being above expectations.
