The Hain Celestial Group (Hain Celestial) has announced that Mark Schiller will replace founder Irwin Simon as president and CEO, effective from 5 November.

The move is part of the company’s efforts to regain its position in natural, fresh and organic food segments. The company is a manufacturer of products such as Terra vegetable chips and BluePrint cold-pressed juices.

In the last fiscal year, which ended in June, the company’s US sales had dipped by 2%.

Natural-foods seller Whole Foods also witnessed decreased sales due to the increase of larger grocers such as Walmart and Kroger entering the natural and organic food market. Whole Foods was bought by Amazon in 2017.

Schiller has more than 25 years of experience in the food industry. Most recently, he served as chief commercial officer for Pinnacle Foods.

Conagra Brands purchased Pinnacle for approximately $8.2bn excluding debt. This transaction was completed last week.

“I look forward to working with the team as we build upon the company’s strong foundation and take Hain Celestial’s business to the next level of growth.”

Schiller said: “I am proud of what we accomplished during my eight years at Pinnacle Foods and believe in driving continuous operational improvements while making disciplined investments in innovation and brand building to achieve success at Hain Celestial.

“I look forward to working with the team as we build upon the company’s strong foundation and take Hain Celestial’s business to the next level of growth.”

Schiller will be nominated as a director of the company at its annual meeting of shareholders, which is scheduled to take place on 5 December.

In June, Hain Celestial announced that Simon will step down as the CEO and serve as the company’s non-executive chairman.

Simon said: “Mark is an incredibly talented executive and I am confident he can lead Hain Celestial in its next phase of growth to generate value for all of our stakeholders.

“His disciplined management style, entrepreneurial spirit and relentless passion for profitable growth will serve Hain Celestial well as our team works to further advance our strategic objectives.”

Headquartered in Lake Success, New York, Hain Celestial is an organic and natural products company with operations in North America, Europe, Asia and the Middle East.
