STAMFORD, Conn. and GREENWICH, Conn., Jan. 20, 2022 /PRNewswire/ — Alliance Animal Health (“Alliance” or “the Company”), a leading acquirer and operator of veterinary hospitals for companion animals, today announced that it has received a significant growth investment from the Flagship Fund of L Catterton, the largest global consumer-focused private equity firm. LightBay Capital will retain a significant minority stake. Terms of the transaction were not disclosed.

Founded in 2016, Alliance Animal Health is a multi-site owner, operator, and business partner to veterinarians across the United States. The Company’s partnership model and infrastructure drives alignment and sustainable business growth while allowing veterinarians to continue to practice medicine independently.

“As we continue to collaborate with our veterinary partners across the United States, L Catterton’s extensive expertise in the consumer healthcare and pet categories will support our mission of connecting and serving pet patients and parents and being the preferred partner for veterinarians,” said Matt Sussman, CEO and Co-Founder of Alliance Animal Health. “This growth investment will enable us to become an even stronger partner to veterinarians, supporting their practices through continued investments in hospitals, training, recruitment, and business resources. I’m grateful for LightBay Capital’s continued partnership and commitment to the business. This investment marks an important milestone in our journey, and we look forward to continuing to build on our strong momentum.”

“Alliance Animal Health is a differentiated business with an attractive platform for sustainable, industry-leading growth,” said Andrew Taub, a Managing Partner in L Catterton’s Flagship Fund. “We know the consumer healthcare and pet sectors well and look forward to leveraging our expertise in collaboration with Alliance’s outstanding team to build on the Company’s success.”

“Alliance operates in a highly fragmented market and we see a compelling opportunity to build density in existing markets and expand into new ones,” added Rajan Shah, a Principal in L Catterton’s Flagship Fund. “We are excited to help Alliance achieve its growth potential and are thrilled to partner with this best-in-class organization.”

“We’re proud of the substantial investments the Alliance team has made in people, process, and technology since our initial partnership in 2019,” said Nav Rahemtulla, Co-Founder and Partner at LightBay Capital. “We’re looking forward to continuing our involvement and working with L Catterton to support Alliance’s success,” added Ben Herman, Partner at LightBay Capital.

L Catterton has significant global experience partnering with leading consumer healthcare and pet businesses.
