MPE Partners has sold MSHS and Pacific Power Group to Industrial Service Solutions, a portfolio company of Wynnchurch Capital. The transaction marks the exit of MPE Partners from its investment in the combined businesses, which provide industrial service solutions and power generation equipment across North America.

MSHS specializes in marine and industrial engine services, while Pacific Power Group distributes and services power generation equipment. The companies had been operating under MPE Partners' ownership, though specific financial terms of the sale were not disclosed in the brief announcement. Industrial Service Solutions' acquisition expands its portfolio of industrial service providers.

The deal represents another successful exit for MPE Partners, which focuses on middle-market industrial companies. For Wynnchurch Capital, the acquisition adds to its growing portfolio of industrial service businesses, though the firm's broader strategy for the combined entity remains to be seen.
