Alastair will continue as a non-executive director, providing his intimate knowledge of the business to aid long-term capital investment decisions.

He joined the business in 1987, taking over from his late father as managing director in 1995. In 2007 he was made chairman and went on some years later to appoint the firm’s first non-family managing director.

In 1995, Macphie’s turnover was £14 million and since then has grown to current year revenues exceeding £73m, delivering record growth over the last three years.

Alastair said: “In four years, Macphie will mark 100 years in business. This is a remarkable achievement and one we look forward to celebrating.

“It has been 29 years since I first took on the role of managing director and it has been amazing watching the company grow. Despite the recent challenges, last year we reported record sales, double-digit growth, and healthy profitability.

“In recent years we’ve strengthened our leadership team with several key appointments – including my nephew Ed Widdowson as strategy, people and sustainability director - to lay the foundations for the next 100 years. Ed is the fourth generation of the family to be involved in the business.”

He continued: “I indicated to the board some time ago my ambition to step down this year and we’ve been working at getting the business into great shape with strong leadership and a clear growth strategy; with that in place, now is the right time to make this transition”.

Macphie CEO Andy Stapley said: “Alastair has been a reassuring constant at Macphie, providing wise counsel, dedication and passion for the business and our people.

“He has overseen huge changes in the company, investing in the manufacturing capability and our people, making sure the business stays ahead of its time, leading on sustainability and meeting the changing needs of our customers.”

Alastair’s stepping down follows last year’s completion of a £5m refurbishment of its Glasgow factory, while plans are advancing for major upgrades to its Glenbervie facility.

As of 1 April, Mr Soutar will take on the role of chairman, with Mr Stapley, who has been in post since 2018, as CEO. Mr Souter first joined the business as a non-executive director in late 2022.

He has had a highly successful executive career in the food sector, bringing over 30 years of leadership experience with household names such as Baxters, Auntie Bessie’s, and William Jackson Food Group.

Mr Soutar said: “I’ve known Macphie for many years, and I’m delighted to take up this appointment and look forward to supporting the business with its ambitious plans.”

On stepping back from the business Alastair still has plenty to keep him busy. He continues to chair the Macphie family non-food businesses and holds several non-executive directorships. It will also allow him “to concentrate his efforts in the community”. In 2020, Alastair was appointed Lord Lieutenant of Kincardineshire, a role which he holds for the next 12 years.
