ESAB to Acquire Eddyfi Technologies for $1.45 Billion

Eddyfi Technologies has always sounded like motion, like signal, like something moving through steel and coming back with the truth. Founded in November 2009 and operational by April 2010, the company grew up inside the hard physics of inspection, where guesses get people hurt and accuracy keeps the lights on. Martin Thériault built it that way from the start, not as a science project but as a business that respected what inspectors actually face at three in the morning with a deadline and a shutdown clock ticking.

That foundation matters now because Eddyfi Technologies is no longer just a clever name in nondestructive testing. It is more than 1,000 people deep, shaped by acquisitions that were about capability, not trophies. Halfwave AS came in with its subsea intelligence in a deal announced February 18, 2020 and closed later that year. Zetec followed, announced in late summer 2021 and closed February 2022 in a $350 million transaction that put serious scale behind advanced ultrasonic inspection. In May 2023, Sensor Networks Inc. joined the fold, adding phased array muscle and bringing Jeff Anderson into the story, first as President and General Manager of SNI, then into a much bigger seat.

As of March 24, 2025, Jeff Anderson carries the President and CEO titles at Eddyfi Technologies. He inherits a company that knows how to listen to metal and a market that is suddenly paying closer attention. Martin Thériault is now Founder, CEO, and Chairman of Previan, the parent company that spent years assembling this portfolio with intent. John Tourlas continues to run global sales, translating physics into purchase orders across industries that do not tolerate maybes.

Then came the moment that made the floor go quiet. ESAB Corporation, founded in 1904 and operating in more than 150 countries with roughly 10,300 employees, stepped forward. Led by Chief Executive Officer Shyam P. Kambeyanda, ESAB outlined 2025 guidance of roughly $2.84 billion in revenue and core adjusted EBITDA north of $539 million, while pointing to a $5 billion expansion opportunity. Inside that context, Eddyfi Technologies is not an accessory. It is signal amplification.

This also marks a structural shift. In June 2025, Previan separated Eddyfi Technologies and NDT Global into independent entities, clarifying focus and accountability. The Eddyfi name keeps doing what it always promised, sending energy into complex assets and pulling back certainty, only now with the backing and expectation that come when industrial giants start listening harder.

Steel remembers everything. Pipes, planes, bridges, and pressure vessels all keep receipts. Eddyfi Technologies has built a business around reading them cleanly, and the next chapter feels less like a finish line and more like a frequency change that serious operators will want tuned in real time.
