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.
