Dana McNabb has been appointed Chief Executive Officer of General Mills, becoming the first woman to lead the 160-year-old food company.

General Mills announced on 30 September 2026 that its board had unanimously elected McNabb, currently Chief Operating Officer, to succeed Jeff Harmening as Chief Executive Officer. The appointment takes effect on 1 January 2027, when Harmening will become Executive Chair of the company’s board.  

McNabb’s appointment comes after a 27-year career at General Mills, where she has held senior positions spanning marketing, general management, international operations, enterprise strategy and growth. She became Chief Operating Officer in June 2026, giving her responsibility for all four of the company’s operating segments and key functions including sales, supply chain, innovation, technology and quality.  

Her promotion places a long-serving company executive at the centre of General Mills’ next phase as the food industry responds to changing consumer behaviour, cost pressures and increasing competition.

McNabb joined General Mills in Canada in 1999 and built her career across several parts of the business.

Her early experience was in marketing, working across the company’s Cereal, Snacks, Meals and Dairy businesses. She later became Vice President of Global Marketing for Cereal Partners Worldwide, the General Mills joint venture with Nestlé based in Switzerland.  

In 2016, McNabb became President of the company’s US Cereal operating unit. She subsequently served as Group President for Europe & Australia, Chief Strategy & Growth Officer and, from 2024, Group President of North America Retail.

In 2025, she added responsibility for General Mills’ North America Pet business before being appointed Chief Operating Officer in June 2026.  

Her career has therefore covered both consumer-facing and enterprise-level responsibilities, from brand marketing and category management to international operations and corporate strategy.

McNabb holds a bachelor’s degree in commerce from the University of Ottawa and an MBA from London Business School. She also serves on the board of Cereal Partners Worldwide. 

General Mills is one of the world’s major food companies, with a portfolio that includes Cheerios, Nature Valley, Blue Buffalo, Häagen-Dazs, Old El Paso, Pillsbury, Betty Crocker, Totino’s and Annie’s.

The company generated fiscal 2026 net sales of $18 billion, while its share of non-consolidated joint venture net sales was $1 billion.  

The company has also changed considerably during Harmening’s tenure as CEO.

Harmening became CEO in 2017 and oversaw changes to the company’s portfolio, including its expansion into pet food through the acquisition of Blue Buffalo. General Mills has also increased its investment in digital capabilities during his leadership. The company said it has delivered more than $17 billion to shareholders through dividends and share repurchases during his tenure and has revamped about a third of its portfolio for growth.  

McNabb will now take over responsibility for the company’s next stage.

McNabb has identified profitable growth as the immediate priority.

In her first statement following the appointment, she said the company would focus on building digitally enabled demand generation and modernising its supply chain as part of an effort to improve how the business operates.  

The focus comes as packaged food companies face a more demanding consumer environment.

Reuters reported that General Mills is dealing with high inflation, pressure on consumer spending and competition from private-label products. The company is also facing higher costs, including tariff-related increases affecting packaging materials.  

General Mills recently reported first-quarter fiscal 2027 results that exceeded analysts’ expectations for sales and profit, while reaffirming its full-year outlook. Reuters also reported that the company’s shares had fallen significantly during 2026 before the leadership announcement.  

McNabb therefore enters the CEO role at a point when the company is seeking to strengthen growth while managing costs and responding to changes in what consumers want from established food brands.

Unlike an external appointment, McNabb’s promotion means General Mills will be led by an executive who has spent almost three decades inside the organisation.

That experience spans the company’s major operating areas and several international markets.

As Group President of Europe & Australia, she led a business that General Mills says returned to growth during her tenure. As President of US Cereal, she led the business during a period when it regained leadership of the US cereal category for the first time in 15 years, according to the company’s executive biography.  

Her more recent responsibilities have given her a broader view of the company.

As Chief Operating Officer, McNabb currently oversees North America Retail, North America Pet, North America Foodservice and International, alongside Sales, Supply Chain and Innovation, Technology and Quality.  

That combination of brand, consumer, operational and strategic experience will now form the basis of her leadership of the entire company.

McNabb’s appointment is notable not only because she is the first woman to become CEO of General Mills, but also because it represents the culmination of a long internal career.

She joined the company at a time when her career was beginning in marketing and has since moved through increasingly senior positions across the organisation.

Her appointment comes amid continued attention on women’s representation in senior corporate leadership. The significance of the General Mills announcement therefore extends beyond a single executive appointment, particularly given the scale and history of the company.

For General Mills, however, the transition is also a business decision centred on continuity and the company’s next phase of growth.

The board said its succession process had been conducted over several years before selecting McNabb. Maria Henry, General Mills’ Independent Lead Director, said McNabb had made significant contributions across the company’s global operations and had a strong understanding of its consumers, brands and industry.  

McNabb will officially become CEO on 1 January 2027, while Harmening moves into the role of Executive Chair.

The leadership transition gives McNabb responsibility for a portfolio of some of the world’s best-known food brands at a time when consumers are becoming increasingly selective about price, value, convenience and product choice.

Her immediate agenda includes returning General Mills to profitable growth, strengthening demand generation and modernising the company’s supply chain.

For McNabb, the appointment represents the latest step in a 27-year career with the company.
