Houston-based private equity firm Ara Partners has purchased Germany’s Vacuumschmelze (VAC), a producer of magnetic materials for products such as electric vehicles, from funds overseen by asset manager Apollo. The purchase price wasn’t disclosed.

VAC is the only producer in the Western Hemisphere of electric-vehicle-grade permanent magnets. It also makes magnetic materials for the industrial, aerospace, medical, and renewable energy sectors.

Earlier this year, VAC announced a deal with automotive giant General Motors to build a North American factory for the production of magnets for the electric motors of GM-made EVs. The factory, set to open in 2025, will initially product enough magnets to supply 1 million EVs each year. The magnets will be made of alloys of rare-earth elements.

GM forecasts it will manufacture 1 million EVs per year in North America by 2025.

“We believe the demand for VAC’s differentiated, customized products will continue to grow rapidly as companies around the world decarbonize their industrial processes and the electrification of mobility advances, and we look forward to leveraging our expertise to further enable VAC’s continued success,” Tuan Tran, a partner at Ara Partners, says in a news release.

Ara Partners specializes in investments in the decarbonization sector.

Founded in 1923, VAC was owned by technology conglomerate Siemens for more than 65 years. Ohio’s OM Group acquired VAC in 2011. Four years later, Apollo purchased OM Group for more than $1 billion, putting VAC in the hands of the asset manager.

As of June 30, Ara Partners had about $4.4 billion in assets under management, while Apollo had $617 billion in assets under management.

The accolades keep coming for Houston-based geothermal energy company Fervo Energy.

Fervo sits atop Time magazine’s and Statista’s 2026 list of America’s Top GreenTech Companies. Fervo ranked No. 6 on the list last year.

The ranking honors 250 companies in the U.S. based on their environmental impact, innovation and financial strength. Fervo joins five other Houston-area companies on the list.

  • No. 49 Quaise Energy, an MIT Energy Initiative spinout that’s developing a drilling system designed to convert existing power stations for geothermal power production
  • No. 71 Plus Power, which develops, owns and operates battery energy storage systems
  • No. 98 Utility Global, whose technology enables industrial decarbonization
  • No. 199 Solugen, whose technology converts plant-based feedstocks into carbon-negative chemicals
  • No. 215 Noodoe, which specializes in EV charging stations and software

Fervo says its approach to enhanced geothermal systems (EGS)—including horizontal drilling, AI-enabled drilling and exploration, advanced reservoir engineering, and fiber-optic sensing—demonstrates how validated technology can help deliver reliable zero-emission power.

“By applying drilling technology from the oil and gas industry, we have proven that we can produce 24/7 carbon-free energy resources in new geographies across the world,” Fervo co-founder and CEO Tim Latimer said last year.

Other recent recognitions for Fervo includes:

  • The 2025 Houston Innovation Awards named it Scaleup of the Year
  • MIT Technology Review put Fervo on its 2025 list of the 10 global climatech companies to watch
  • Time named Fervo one of the 100 Most Influential Companies of 2025
  • Fervo was hailed as the Global Cleantech Group 100 North American Company of the Year
  • Fervo was among Congruent Ventures’ and Silicon Valley Bank’s 50 by 2050 companies, all of which are poised to advance global decarbonization over a 25-year span
Just last month, Fervo secured $421 million in debt financing for the construction of its 500-megawatt Cape Station geothermal project in Utah. And in December, the company landed an oversubscribed $462 million Series E round of funding, pushing its valuation to an estimated $1.4 billion. Fervo filed for an IPO earlier this year.
