McDonald's (MCD) is shaking up its board of directors with three new appointments as long-serving member Sheila A. Penrose retires.

Penrose sat on the McDonald's board for over 15 years, leading the chain's Sustainability and Corporate Responsibility Committee. She is set to retire on Sept. 30.

"For over 15 years, Sheila has been a deeply committed and highly valued member of our Board. We have all benefited from her thoughtful counsel, strong expertise and unwavering dedication to McDonald's," Enrique Hernandez, Jr., McDonald's chairman of the board, said in a statement.

New appointments to McDonald's board include Anthony Capuano, CEO at Marriott International; Jennifer Taubert, executive vice president and worldwide chairman of Pharmaceuticals at Johnson & Johnson; and Amy Weaver, president and chief financial officer at Salesforce. The election of Capuano, Taubert, and Weaver will take place on Oct. 1.

Capuano will bring his experience in real estate and his leadership of Marriott with a focus on franchising and driving digital customer engagement, while Taubert will provide her expertise in global business, especially in dynamic environments. Weaver will come to the board with extensive financial, legal, and digital experience.

Chris Kempczinski, McDonald's president and CEO, said, "I'm excited to welcome Tony, Jennifer and Amy to McDonald's. They are inspiring leaders with a demonstrated track-record leading large, complex organizations. Their experience stewarding some of the world's most respected global brands will benefit McDonald's greatly and position the company for continued growth."

The news of the board appointments comes as McDonald's made a splash in the last few days with reports that it was testing a Chicken Big Mac in select restaurants in Miami. The menu move is one of its latest attempts to garner more customers, the Washington Post reported.

The chain previously tested the Chicken Big Mac in the U.K. to an overwhelmingly positive response from consumers, the news outlet said. McDonald's has also partnered with numerous celebrities to create special combo meals.

The company also recently ended the testing of its McPlant – a plant-based burger – which analysts said generated disappointing results. McDonald's said the tests "concluded as planned," according to Restaurant Dive.

As of Monday premarket hours, shares of McDonald's were trading at $264.45, down $2.09, or 0.78%.
