April 6, 2026. Antin Infrastructure Partners has acquired Sapphire Gas Solutions, a vertically integrated provider of compressed natural gas (CNG) and liquified natural gas (LNG) solutions, from funds managed by affiliates of Apollo. The acquisition is being made by Antin’s Flagship Fund V.
Founded in 2005 and headquartered in Conroe, Texas, Sapphire provides critical, low carbon energy solutions to utility, commercial & industrial (C&I) and renewable natural gas (RNG) customers. The company owns and operates specialized infrastructure to compress, liquify, transport and store CNG and LNG for end users. It currently operates in 30 US states, serving over 120 customers.
Sapphire benefits from significant tailwinds within the US energy sector as C&I and data center load growth outpace existing infrastructure capacity and create a fundamental need for resilient, on-site energy solutions. Sapphire’s CNG and LNG solutions represent an economically attractive alternative and allow customers to reduce carbon emissions, especially when supplied as RNG. With Antin’s support, Sapphire is well positioned to capitalize on these favorable energy reliability and sustainability trends.
Founder and CEO Sam Thigpen will continue to lead Sapphire’s management team, which brings deep sector expertise and a proven track record of delivering unique technical solutions for its customers, complementing Antin’s expertise in investing in and growing infrastructure businesses.
