Audax Private Equity, an alternative investment manager, completed the acquisition of S.J. Electro Systems, a controls technology company. Financial terms were not disclosed. “We believe that positive industry tailwinds coupled with the current fragmentation of the wastewater control solutions manufacturing market strategically positions SJE to continue to scale through both organic and inorganic growth opportunities. We look forward to working closely with Dave and the entire team as SJE enters its next phase of growth," Jay Mitchell, Audax Private Equity Managing Director.
