Republic Services Inc., a US-based provider of environmental services and solid waste management solutions, has acquired Shamrock Environmental, a regional wastewater treatment firm. The transaction closed on February 14, 2025, with the financial terms not disclosed publicly.

Acquirer: Republic Services Inc.
Target: Shamrock Environmental (US)

Closing Date: February 14, 2025

The deal sees Republic Services expanding its footprint in the growing wastewater treatment market along the East Coast from Florida to Pennsylvania. This strategic move aligns with the company's objective to bolster its portfolio of waste processing and environmental services.

Shamrock Environmental was previously a portfolio company of CenterOak Partners, a private equity firm that partnered alongside management to build the business over several years into a scaled provider.
