Walgreen Boots Alliance CEO Rosalind Brewer has stepped down from the company, leaving it now with two vacant top executive roles.

The board and Brewer “mutually agreed” she would leave the company and its board effective yesterday, Deerfield, Illinois-based Walgreens said in a press release this morning.

Walgreens’ board has appointed Ginger Graham, the company’s current lead independent director, as its interim CEO. Brewer will advise Walgreens as it searches for a permanent CEO, a role for which she will receive a monthly consulting fee of $375,000 through February 2024, according to a Walgreens U.S. Securities & Exchange Commission filing.

Brewer has also been given a separation and transition agreement that provides her with $9 million in cash severance, which is equal to two times the sum of her base salary plus her target annual bonus, according to the filing. She will also receive payment of any annual bonus earned in this current fiscal year and will vest in the remaining unvested portion of her long-term incentive package.

“I am grateful to have had the opportunity to lead Walgreens Boots Alliance and to work alongside such talented and dedicated colleagues,” Brewer, 61, said in the press release. “I am confident that (Walgreens) is on track to be a leading consumer-centric health care company, serving thousands of communities across the country, especially those that need access to health care the most.”

Brewer's departure comes shortly after Chief Financial Officer James Kehoe announced in July that he was leaving for an opportunity in the technology sector.

Walgreens’ stock was down 5.6% late Friday morning. The company declined to comment further beyond its press release.

“On behalf of the entire board, I would like to thank Roz for her contributions to WBA,” Walgreens Executive Chairman Stefano Pessina said in the press release. “Roz navigated the company through the global pandemic, overseeing the critical rollout of vaccines in Walgreens pharmacies and to high-risk populations across the country. She furthered our consumer-facing capabilities while supporting the culture of community and team-member engagement in difficult times. We appreciate her hard work and commitment to the company during this period of unprecedented change.”

Brewer, Walgreens’ first Black and woman CEO, joined the company just as COVID-19 vaccines were becoming available to the public, making its pharmacies a key destination for many Americans seeking the vaccines. With more people in stores, Walgreens’ business saw a boost that has begun to falter as the pandemic subsides.

Brewer also joined Walgreens at a time when the company was embarking on a transformation to shift away from its traditional pharmacy retail roots and toward a health care company that offers primary care in its network of more than 8,000 stores. As part of the health care plan, Brewer oversaw Walgreens’ acquisitions of two assets, including post-acute and home care firm CareCentrix and specialty pharmacy Shields Health Solutions.

So far, the health care plan hasn’t paid off for Walgreens, which employs 325,000 people. The company missed Wall Street estimates and slashed its full-year profit forecast when it revealed its most recent earnings in June. Walgreens’ stock fell as much as 11% that day, the lowest level since late 2010 and the company’s biggest intraday loss since Nov. 17, 2020, when online retail giant Amazon.com said it would expand its push into U.S. prescription drug sales.

In today’s press release, Walgreens also disclosed that it expects its full-year 2023 adjusted earnings per share to be at or near the low end of its previously stated range of $4 to $4.05 a share. Walgreens’ next earnings call is expected to take place in mid-October.

Amid the financial trouble, Walgreens has laid off hundreds of employees this summer and announced plans to close 450 stores in the U.S. and U.K.

Investors also haven’t expressed enthusiasm for Walgreens’ plan. The company’s stock is down 28% over the past year.

Even still, Walgreens leaders have told investors they are committed to the health care strategy despite trying to break into a competitive and crowded industry.

Walgreens also now faces a threat from CVS Health with the latter's launch of a new biosimilar commercialization business. CVS Health is expanding its enterprise in a manner that could pose competitive threats to Walgreens and global drug manufacturer AbbVie.

Before Walgreens, Brewer did a stint as chief operating officer at Starbucks. Before that, she was CEO of warehouse retailer Sam’s Club, a division of Walmart.

Unlike Brewer, who had no health care experience, her interim replacement, Graham, comes to the role after holding health care leadership positions over the past three decades. From 2003 to 2007, she was president and CEO of Amylin Pharmaceuticals. Prior to that, she was group chairman for cardiology medical technology Guidant.

Graham has been on Walgreens’ board since 2010 and was named its lead independent director in October 2022.

“By capitalizing fully on the strength of WBA’s strong mission, values, and brand we have an enormous opportunity to play an even more valued role in local healthcare delivery,” Graham said in the press release. “My focus will be on our people and our operations, working together to drive shareholder value creation and ensuring a smooth transition as soon as we identify the next CEO for the future.”

In an analyst report Friday morning, Elizabeth Anderson, a managing director and research analyst at Evercore ISI, wrote that it “makes sense” for Walgreens to search for new leadership with a health care background.

“The timing of today’s announcement will likely take many by surprise, but the event less so given the magnitude of the company’s core pharmacy business concerns and the (year-to-date) stock performance,” Anderson wrote. “Given the recent company performance, we do see the interim CEO and CFO positions as potentially creating some investor unease, particularly as the business is at a core inflection point.”
