This study examines how climate-related natural disasters affecting auditors personally influence audit quality. Using cognitive resource and stress-and-coping theories, we argue that disaster exposure strains auditors’ information processing, risk assessment, and professional skepticism, increasing the likelihood of audit deficiencies. Drawing on U.S. PCAOB Form AP data from 2016–2024, we link partners’ residential addresses to county-level disasters and employ a difference-in-differences design. We find that audits led by disaster-exposed partners exhibit lower audit quality, reflected in higher rates of restatements and material restatements, with the results remaining robust across alternative specifications. Our additional analyses indicate that the documented decline in audit quality is not driven by concurrent client or audit office exposure to natural disasters but instead reflects audit partners’ personal disruptions. We also find evidence of spillover effects from affected partners to their client portfolios, and the decline in audit quality remains consistent across different levels of disaster severity. Our findings show how contemporary life shocks shape professional judgment and offer implications for audit firms and regulators amid intensifying climate-related disruptions.
