Sentinel Closes Sale of Spectrum Safety Solutions' Autronica Unit

Divests Global Leader in Fire, Smoke, and Gas Detection Solutions

NEW YORK, July 9, 2026 /PRNewswire/ -- Sentinel Capital Partners, a private equity firm that invests in promising midmarket companies, today announced the sale of 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, for $555.0 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 from Carrier Global Corporation (NYSE: CARR) as part of a complex carveout that created Spectrum Safety Solutions. During Sentinel's ownership, Autronica strengthened its global commercial organization, expanded its product portfolio, and further reinforced its leadership in mission-critical fire and gas detection. In March 2026, Sentinel also agreed to sell Spectrum's Marioff unit, a provider of high-pressure water mist fire suppression solutions, to private equity firm Inflexion. Together, these divestitures position Spectrum to focus on its U.S.-headquartered detection and monitoring businesses, Det-Tronics and Fireye.

"Sentinel has been a valued partner throughout this important chapter of Autronica's development," said Sindre Utne, Autronica's CEO. "Their strategic support helped us accelerate growth while remaining focused on our employees, customers, and long-term vision. We're proud of and grateful for what we accomplished together."

"It's been a privilege to work alongside Sindre and the talented Autronica team," said Eric Bommer, Sentinel's Co-Managing Partner. "Over the past two years, the team has strengthened the business, expanded its global footprint, and built a strong foundation for the future. We thank them for a productive partnership and wish them continued success 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).

Citi and J.P. Morgan served as exclusive financial advisors to Sentinel, and Kirkland & Ellis provided legal counsel.
