Investment company Mitchell Family Office (MFO) has acquired Cos Bar, a luxury multi-brand beauty retailer in the US.

The financial terms of the deal have not been disclosed.

Founded in 1976, the retailer operates stores throughout the US and serves a “highly engaged” luxury clientele.

MFO managing partner Mark Mitchell said: "Cos Bar is a brand with deep heritage, a loyal client base, and a phenomenal reputation for excellence in luxury beauty.

"We are thrilled to partner with the Cos Bar team to honour the company's legacy while positioning it for future growth. At MFO, we invest in brands with strong founders and passionate leaders, and we see tremendous opportunity to build on Cos Bar's success with innovation, scale, services and technology."

The retailer already operates an omnichannel distribution network and plans to expand geographically.

MFO said it will support Cos Bar’s “evolution” and its “vision for the future” as the company enters its next chapter.

Cos Bar CEO Oliver Garfield said: "MFO is the ideal partner for Cos Bar's next chapter. Their proven track record of success in growing impactful businesses and shared values perfectly aligns to build on our legacy and accelerate growth as Cos Bar approaches the milestone 50th anniversary.

“Together, we will be able to expand our reach, enhance the client experience, and continue to set the standard in luxury beauty retail."
