Tyler Mulier's questions to Donaldson Company Inc (DCI) leadership • Q3 2025
Question
Tyler Mulier, on behalf of Brian Drab from William Blair, questioned the sustainability of the aftermarket business's growth, given an implied deceleration in Q4 guidance. He also asked about visibility in the Aerospace & Defense segment and the potential for tough comparisons in fiscal 2026.
Answer
CEO Tod Carpenter attributed the aftermarket's strength to typical seasonality where Q3 and Q4 are strongest, combined with successful market share gains. For Aerospace & Defense, he confirmed long-term project visibility but noted that near-term lumpiness is difficult to predict due to supply chain uncertainties. He expressed confidence in the segment's strength despite these challenges.
