The Deal
Audax Private Equity first partnered with Rensa in 2022.

Following this success, Audax and Rensa trusted Lincoln to leverage its deep sector expertise within the filtration market and its broad relationships across the financial sponsor and strategic buyer universe to identify the ideal partner. The partnership with AEA and British Columbia Investment Management Corporation (BCI) will support the company’s continued growth strategy as a global leader within filtration.
Joe Rogers, a Partner at Audax Private Equity, said, “Lincoln was an exceptional partner to Audax and the Rensa team throughout this transaction.”
Matt Gosselin, a Managing Director at Audax Private Equity, added, “Lincoln’s deep knowledge of the filtration sector, thoughtful positioning of Rensa’s differentiated platform and growth opportunities and strong execution capabilities were instrumental in achieving a successful outcome.”

The high level of interest generated throughout the process reflected both the quality of the business and the strength of the platform Brandon and the Rensa team have built in partnership with Audax.
