Nestlé has appointed Antonia Wanner as chief communications and sustainability officer and a member of the group's executive board, expanding her responsibilities beyond sustainability to include corporate communications.Wanner succeeds Lisa Gibby, who will leave the company later this year and return to the United States after more than three years leading the communications function.The leadership change comes during a period of significant transformation for the Swiss food and beverage giant. During Gibby's tenure, Nestlé navigated multiple CEO transitions, operational restructuring and a series of high-profile corporate challenges, including scrutiny of its bottled water business, concerns over infant formula sugar content, a global product recall affecting dozens of markets, and workforce reductions.Reflecting on her time at the company, Gibby said: "It's been an extraordinary journey—supporting leadership changes, navigating complex issues, and helping transform the communications function along the way. It challenged me in ways I couldn't have imagined and remains one of the most rewarding chapters of my career."Gibby joined Nestlé's global leadership team in 2023 after serving as vice-president of corporate communications for the company's US operations. Earlier in her career, she held the role of director of global communications at ONE Campaign and founded LKG Communications, a consultancy serving corporate and advocacy clients.Wanner brings nearly three decades of experience within Nestlé. Since joining the company in Germany as an in-house lawyer in 1996, she has held senior leadership roles across legal, procurement, sales and sustainability functions. Most recently, she served as chief sustainability officer, leading the company's environmental and social responsibility agenda.Nestlé CEO Philipp Navratil said the move reflects the company's intention to more closely align communications and sustainability."Antonia will make corporate communications an even stronger driver of business impact, closely aligned with our strategic priorities and focused on disciplined execution. Bringing corporate communications and sustainability closer together will strengthen credible stakeholder engagement and support long-term value creation," he said.
