Amberjack Capital Partners (“Amberjack”) is pleased to announce the sale of Milestone Environmental Services (“Milestone” or the “Company”), a portfolio company of Amberjack Capital Fund I, to SK Capital Partners.

Milestone was founded in 2014 via a partnership between the Company’s executive management team and Amberjack to pioneer a proprietary and environmentally superior method of disposing mission-critical and challenging energy waste streams.  Since inception, Milestone has grown into the leading independent energy waste management platform throughout the United States’ most productive energy regions.  The Company provides a secure means for its customers to permanently sequester hydrocarbon-containing energy waste, thereby preventing greenhouse gas emissions and groundwater contamination.  More recently, the Company created a new business segment, Milestone Carbon, and emerged as a leader in permanent carbon sequestration services.  Leveraging the Company’s core competencies in energy waste sequestration, Milestone Carbon is focused on developing and operating injection sites that permanently sequester CO2 to enable a broad range of emitters to achieve their decarbonization goals.

The team at Amberjack could not be prouder of the Milestone team for building the innovative and market-leading company Milestone has become.  We are grateful to the Company’s management team for the many years of partnership and we commend CEO Gabriel Rio and CFO Frank Schageman for their stewardship of the business since the Company’s founding.  Amberjack is honored to have supported the Company during its formative years of development and looks forward to the Company’s continued growth and development.
