MSA Safety said it will buy Autronica Fire and Security for about $555 million, adding a fire and gas detection business that generated roughly $160 million in sales in 2025.
The deal values Autronica at about 3.5 times its 2025 revenue and comes as MSA looks to deepen its position in critical infrastructure, energy and maritime markets. Autronica, founded in 1957 and based in Trondheim, Norway, employs about 500 people worldwide.
MSA said the acquisition should close in the third quarter of 2026. It plans to fund the purchase with cash on hand and borrowings from its existing credit facility.
Autronica’s 2025 adjusted EBITDA margin was about 20%, implying roughly $32 million in adjusted EBITDA on last year’s sales. MSA said the transaction is expected to be accretive to adjusted earnings per share in the first full year of ownership and to add to growth and margins.
For MSA, the acquisition expands its fixed detection business and increases its exposure to a market it described as more than $3 billion. The company said Autronica’s technology should help it get involved earlier in project design and deliver more integrated safety systems across high-hazard applications.
MSA itself reported 2025 revenue of $1.9 billion and has about 5,300 employees across more than 40 international locations. Today the company's shares have moved 5.02% to a price of $173.56. Check out the company's full 8-K submission here.
