USANA Health Sciences, Inc. (NYSE:USNA) announced today a leadership transition as part of the Company's ongoing commitment to accelerating growth and enhancing shareholder value. Kevin Guest is returning to lead the Company as Chief Executive Officer, effective immediately. Mr. Guest, who has spent more than three decades at the Company, including eight years as CEO and the last three years as Executive Chairman, has agreed to again serve as USANA's CEO and will continue serving as Chairman. Mr. Guest succeeds Jim Brown, who has stepped down from his position of CEO and President.

"We thank Jim for his contributions and his leadership over the past 19 years and in his role as CEO over the past 3 years," said Gilbert Fuller, lead independent director of the Board. "As USANA enters its next phase, the Board believes this transition will position the Company to accelerate strategic priorities that meaningfully contribute to long-term growth opportunities."

"Kevin has the full support of the Board and the Company's senior leadership team. He also has good relationships with the Company's sales force and brings a combination of deep sales, organizational and strategic experience," continued Mr. Fuller.

"I am truly energized to return to the Company and lead this exceptional organization once again," Mr. Guest said. "I know firsthand the strength of our sales force and management team, the resilience of our culture, the differentiation of our science-based products, and the meaningful opportunities ahead. I'm grateful to the Board for their confidence, and I look forward to working closely with our team to drive the next chapter of sustainable growth."

During his eight years as CEO, from 2015 to 2023, Mr. Guest guided USANA through a period of meaningful global expansion, strengthened operational performance, and elevated the Company's position as a leader in health and wellness. Under his leadership, USANA achieved record results, deepened its presence across key international markets, and reinforced a culture of excellence that continues to define the organization today. His ability to build high‑performing teams, navigate complex industry dynamics, and maintain a clear strategic vision earned the confidence of the Board and the broader USANA community.
