PITTSBURGH, May 5, 2026 /PRNewswire/ -- MSA Safety Incorporated (NYSE: MSA), a global leader in the development of advanced industrial safety technology products and solutions that protect people and facility infrastructure, today announced it has entered into a definitive agreement to acquire Autronica Fire and Security ("Autronica") for approximately $555 million.

Founded in 1957, Autronica is a designer, manufacturer, and supplier of fire detection, gas detection, and alarm systems. Autronica serves the critical infrastructure, energy, and maritime sectors. Based in Trondheim, Norway, Autronica employs approximately 500 employees globally.

"We are excited to welcome Autronica to the MSA Safety family," said Steve Blanco, MSA Safety President and CEO. "This acquisition accelerates our fixed detection growth strategy by adding a highly complementary, scaled fire and gas systems business. Autronica enhances our ability to participate earlier in project design and to deliver more integrated safety solutions across critical infrastructure, energy, and marine applications. The acquisition marks another key pillar of our Accelerate strategy, reinforcing our focus on expanding our detection platform and advancing our portfolio through strategic acquisitions," he said.  

"With Autronica's strong technological expertise and leadership in fire and gas safety systems, we expect to leverage the combined portfolio to further enhance our ability to meet demanding customer safety requirements across high–hazard and regulated environments," Mr. Blanco continued. "The combination positions MSA to expand into a large, growing addressable market supported by regulatory drivers, technical complexity, and long renewal cycles for mission–critical assets. In addition, Autronica's complementary geographic footprint enables both organizations to leverage regional strengths, expand global reach, and deliver greater value to customers worldwide. Autronica's mission statement, zero loss of lives, is strategically aligned with MSA's Mission, Vision and Values."

Commenting on the transaction, Autronica CEO, Sindre Utne said, "Joining MSA Safety marks an exciting next step for Autronica. MSA's leadership position in safety and detection technologies, its strong systems and solutions capabilities, and its long-standing customer relationships make it an ideal owner as we work to maximize our growth potential." He added, "By leveraging MSA's global market reach, distribution channels, and deep detection expertise, we see a significant opportunity to expand and combine our solution offering, deepen engagement with customers earlier in the project lifecycle, and extend our reach well beyond the installed base and the markets we serve."

The transaction is expected to close in the third quarter of 2026, subject to customary closing conditions and regulatory approvals, and will be funded through a combination of cash on hand and borrowings under MSA's existing credit facility. The acquisition is expected to be accretive to growth and margins, with synergies. Autronica is a capital-efficient business that generates significant free cash flow and is expected to be accretive to adjusted EPS in the first full year of ownership. In 2025, the company recorded approximately $160 million in sales with an adjusted EBITDA margin of approximately 20%.
