Cyberattack causes company-wide operational disruption and order backlog at Simpson Manufacturing

On October 10, 2023, Simpson Manufacturing disclosed unauthorized activity affecting its information technology infrastructure and applications. The company took systems offline to contain the incident. SEC filings subsequently confirmed approximately three days of widespread business disruption, while the company's annual reporting identified a resulting backlog of orders that was fulfilled within approximately one week. The documented interruption of shipment and order-fulfillment activities establishes a material operational consequence. The company later reported no material financial impact to its business.
