Mid-market private equity firm Straight Bat has sold the majority of its stake in Kase Building and Restoration Group back to the company's founder, simultaneously slashing the investment's value by 64 percent.

The transaction, disclosed late Tuesday, marks a decisive exit for the investor after a period of underperformance at the building services provider.

The steep valuation haircut underscores the challenges facing some mid-market buyouts in the construction and restoration sector.

By returning control to the founder, Straight Bat effectively cedes operational influence while crystallizing significant losses on the position.

The move suggests a strategic retreat from an asset that failed to meet the firm's return hurdles.

This development adds to a broader narrative of portfolio pruning among private equity firms as they reassess holdings in cyclical industries.
