ABSTRACT This study examines whether CEO managerial ability shapes the repetition of firms' climate‐related disclosures in mandatory 10‐K filings. Climate reporting is highly judgment based and central to firms' broader climate‐risk management strategies, yet little is known about why some firms repeatedly use similar climate narratives and others revise them extensively. Using 12,533 US firm‐year observations from 2005 to 2023, we measure climate‐disclosure repetition through four dictionary‐based similarity metrics and an AI‐based semantic embedding approach. CEO ability is captured using an efficiency‐adjusted managerial ability score. The results show that firms led by higher‐ability CEOs provide more repetitive climate narratives over time. These findings remain robust across matching procedures, entropy balancing, within‐year disclosure‐alignment tests, lagged‐ability models, and change‐on‐change specifications. Overall, the study highlights managerial capability as an important driver of firms' long‐term climate‐communication strategies and introduces intertemporal repetition as a novel dimension of climate‐disclosure practice.
