Advent International and Leonard Green & Partners to Partner with Genstar Capital and Management to Drive Next Chapter of Growth at Prometheus Group

Additional Investment and Resources to Accelerate Prometheus Group’s Expansion and Growth in the Industrial Software Space

RALEIGH, June 5, 2024 Prometheus Group (“Prometheus”), a Genstar Capital (“Genstar”) portfolio company, announced today that Advent International (“Advent”), joined by Leonard Green & Partners (“LGP”), will make a significant strategic investment in the company. As part of the transaction, Genstar, which acquired Prometheus Group in 2019, and Eric Huang, CEO and founder of Prometheus, will continue to retain meaningful stakes in the company.

Eric Huang commented, “Prometheus Group’s intuitive enterprise asset management software solutions help clients optimize productivity and efficiency by breaking down the functional silos between maintenance, operations, and engineering. We are very thankful for Genstar’s leadership over the past five years and will rely on their continued guidance. We have only increased our capabilities with the addition of Advent, one of the world’s largest and most experienced global private equity investors, and LGP, a top-tier growth-focused and management-first private equity firm. We have already benefited from the valuable and actionable insights we gleaned from Advent and LGP during the investor process. We look forward to taking advantage of Advent’s international reach and network of industry veterans to significantly bolster our aspirations of being a truly global operator. LGP’s proprietary approach towards growth, leading research operations, and business network will significantly reduce our learning curve as we begin the next leg of our journey.”

Prometheus Group’s solutions utilize intuitive software and data analytics to deliver a uniform experience across the platform and are trusted by the largest asset-intensive companies in the world operating in the oil & gas, chemical, pulp & paper, mining & metals, utilities, food & beverage, and pharmaceutical industries. The company has completed a number of strategic acquisitions since 2019 to expand its offerings in the industrial maintenance software space, with the additional products allowing operators to simplify maintenance and gain additional savings and operational efficiencies from their asset data.

With this incremental investment, Prometheus plans to continue its commitment to innovation and excellence by extending its already comprehensive suite of industrial maintenance software solutions. The company will also expand its customer service and go-to-market efforts, with a particular focus on international markets including Europe and Asia. With this investment, Prometheus aims to support its clients’ maintenance and operations efforts even more broadly across their organizations and asset bases.

Eric Wei, Managing Director at Advent, said, “Many asset-intensive industries are still in the early innings of their digitization journey, and we see a long runway for Prometheus to continue to expand beyond its already strong customer base, especially by extending its reach internationally. Eric and his team have developed an innovative end-to-end product that has been purpose-built for the maintenance and operations workflow. We are excited to leverage Advent’s multi-sector footprint and global presence to help accelerate Prometheus’ impressive growth in partnership with management, Genstar, and LGP.”

Usama Cortas, Partner at LGP, said, “Prometheus is an exceptional company – exactly the type of company with which we like to partner. We invest in companies that win with people, have a differentiated culture, and are market leaders with multiple levers for growth. Prometheus has built an incredibly successful track record of helping customers optimize asset management, maintenance, and operations. We are thrilled to partner with Advent, Genstar, Eric Huang, and the broader Prometheus team and look forward to supporting the continued growth of the business.”

Eli Weiss, Managing Partner at Genstar Capital, said, “It has been an honor and pleasure to work with Eric Huang and the Prometheus team to build the business together over the last five years.  This milestone is a great achievement, and we look forward to continuing to the next chapter of ownership with the Prometheus team, Advent, and LGP.”
