PHINIA announced Tuesday it has entered into a definitive agreement to acquire all of the issued and outstanding shares of Swedish Electromagnet Invest AB (SEM).

Founded in 1915, PHINIA states SEM is a prominent provider of advanced natural gas, hydrogen and other alternative fuel ignition systems, injector stators and linear position sensors primarily for the commercial vehicle, industrial and off-highway markets.

Under the terms of the agreement, PHINIA will pay $47 million (452 million Swedish krona) for the acquisition of SEM, which is expected to generate approximately $50 million of annual revenue and approximately $10 million of annual adjusted EBITDA. The transaction, which is subject to customary closing conditions, is expected to close in the third quarter of 2025, PHINIA states. 

PHINIA expects the acquisition to enhance PHINIA’s product portfolio and strategy, enabling the company to explore adjacent market opportunities and provide customers with a wider range of products and turnkey solutions. The company states the move not only strengthens PHINIA’s commitment to sustainability but also establishes the company as a key player in the transition towards alternative fuel technologies.

“SEM’s product portfolio complements PHINIA's business by adding over a century of industrial experience and expertise in advanced ignition solutions for on- and off-road commercial and industrial engines,” says Brady Ericson, president and CEO at PHINIA. 

“The acquisition aligns with PHINIA’s strategy of exploring alternative, carbon-neutral and carbon-free fuels, and expanding its presence in the commercial vehicle, industrial and aftermarket sectors. This positions PHINIA to lead the development of zero- and lower-carbon solutions, supporting our journey towards carbon neutrality.”

PHINIA and SEM’s complementary portfolios broaden the range of technical solutions PHINIA can bring to its customers. In particular, the combination of PHINIA’s Engine Management System experience and SEM’s significant experience with advanced ignition systems strengthens PHINIA’s position as a full system provider. The company says adding ignition systems to the existing PHINIA portfolio of fuel system components, electronics, software and calibration capabilities will bring further opportunities to optimize the combustion process and strengthen PHINIA’s value proposition.
