About this update from Msa Safety Incorporated

Strategic Divestiture of Global Leader in Fire, Smoke, and Gas Detection Solutions NEW YORK, May 5, 2026 /PRNewswire/ -- Sentinel Capital Partners, a private equity firm that invests in promising midmarket companies, today announced that it has signed a definitive agreement to sell Autronica Fire and Security, a standalone unit of its Spectrum Safety Solutions platform, to MSA Safety (NYSE: MSA), a global leader in safety products and technology. The transaction is valued at approximately $555 million. Headquartered in Trondheim, Norway, Autronica is a designer, manufacturer, and supplier of fire detection, gas detection, and alarm systems for many critical infrastructure, energy, and maritime applications. Autronica holds numerous regulatory certifications for harsh environments, with a mission to protect life, environment, and property. Sentinel acquired Autronica in 2024 in a carveout of Carrier Global Corporation's industrial fire business, now Spectrum Safety Solutions. In March 2026, Sentinel also agreed to sell Spectrum's Marioff division, a provider of high-pressure water mist fire suppression solutions, to private equity firm Inflexion. The divestitures of Autronica and Marioff position Spectrum to focus on its U.S.-headquartered detection and monitoring businesses, Det-Tronics and Fireye. "We appreciate Sentinel's support and strategic guidance over the past two years," said Sindre Utne, Autronica's CEO. "Their partnership helped us scale thoughtfully and expand geographically while staying true to our culture and commitment to excellence." "We're proud to have partnered with Sindre and the entire Autronica team," said Eric Bommer, Sentinel's Co-Managing Partner. "It's been rewarding to participate in the company's growth and development. Autronica is well positioned to continue its impressive growth trajectory as part of MSA Safety." Sentinel's experience in industrials includes investments in Alemite (industrial lubrication equipment and components); Chromalox (commercial and industrial electric heating products and systems); ECM Industries, NSI Industries, and Power Products (electrical products); IEP Technologies (systems and services that suppress, isolate, and vent combustible dust or vapor explosions); and RotoMetrics (rotary tooling products).
