US-based smoothie franchise Smoothie King has entered a minority growth investment agreement with private equity company Main Post Partners.

Details of the size of the investment were not shared by either party.

Smoothie King, established in 1973, operates 1,200 stores throughout the US and is headquartered in Dallas, Texas.

In its press release, Smoothie King stated that the collaboration opens a “powerful new chapter” for the company, enabling “accelerated growth, innovation and market leadership”.

The investment reflects a “strong vote of confidence” in the company’s “vision, team, and long-term potential."

North Point served as Smoothie King’s exclusive financial advisor for the deal.

Smoothie King majority shareholder and CEO Wan Kim stated: “At Smoothie King, our vision is to make the world a better place by nourishing healthy habits, and that starts with having partners who share our vision and embrace our values.

“We have been extremely impressed by Main Post's track record of growing franchise brands the right way – by building a strong culture, focusing on the guest, and always thinking long term.”

Main Post managing partner Jeff Mills stated: "We are very impressed by the strength of the Smoothie King brand and reputation, the quality and innovation of the product offerings and its commitment to the guest experience.

“We are excited to partner with Smoothie King's strong leadership team and franchisees to support the company in capitalising on its Clean Blends menu, impressive customer service ranking, 1,200-plus unit restaurant base and category leadership.

“Smoothie King is well-positioned to enter its next phase of growth and fulfil its bold and inspiring vision to become one of America's favourite brands.”
