Mark Schneider and Robert Davis are not publicly documented as relatives, longtime colleagues, or direct business partners. The clearest verified connection is professional: Ulf Mark Schneider, the former CEO of Nestlé, and Robert M. Davis, chairman and CEO of Merck, were both listed as members of the American Heart Association CEO Roundtable in 2023.
That distinction matters because both names belong to high-profile corporate executives with substantial experience in health-related industries. Their careers have crossed within the same executive leadership network, but authoritative corporate records do not show that they worked for the same company or held a direct business partnership.
Mark Schneider and Robert Davis: the verified connection
The strongest documented link between Schneider and Davis comes from the American Heart Association’s CEO Roundtable, a collaboration of major corporate leaders focused on employee health, health-care access, mental well-being, innovation and evidence-based workplace health programs. The organization says participating companies collectively represent millions of employees and family members.
A CEO Roundtable membership roster updated on November 27, 2023 lists:
| Executive | Company on 2023 roster | Position listed |
|---|---|---|
| Mark Schneider | Nestlé | CEO |
| Robert M. Davis | Merck | Chairman and CEO |
Both appear on the same membership page, with Davis and Schneider positioned next to one another in the published roster.
This shared membership establishes a genuine professional overlap. It does not, however, establish a personal friendship, financial partnership, family relationship or direct corporate alliance between the two men.
One plausible reason the names are paired in online searches is this executive network and its published membership materials.
Who is Mark Schneider?
Ulf Mark Schneider, usually known professionally as Mark Schneider, is a German-American business executive best known for leading Nestlé and, before that, health-care group Fresenius.
Nestlé’s official biography records Schneider as CEO of Fresenius Group from 2003 to 2016. He became Nestlé’s chief executive in 2017, after earlier positions including CFO of Fresenius Medical Care and several senior roles within the Haniel Group. He holds a finance and accounting degree and doctorate from the University of St. Gallen and an MBA from Harvard Business School.
Schneider’s background is unusual for the leader of a global food and beverage company because much of his earlier executive career was spent in health care. At Nestlé, that experience coincided with the company’s continued emphasis on areas such as nutrition, health science, pet care and higher-growth consumer categories.
Why did Mark Schneider leave Nestlé?
Nestlé announced in August 2024 that Schneider would relinquish his positions as CEO and member of the company’s board, with Laurent Freixe taking over effective September 1, 2024. Nestlé credited Schneider with shaping its portfolio during approximately eight years in charge, particularly around coffee, pet care and nutritional health products.
Schneider therefore should no longer be described as the current CEO of Nestlé.
What is Mark Schneider doing now?
As of 2026, Schneider remains active in major corporate governance roles.
Roche lists him as a member of its Board of Directors since 2023. Its current biography records his Nestlé tenure as 2017 to 2024 and also lists his membership on the Siemens Supervisory Board.
Roche shareholders re-elected Schneider to the company’s board at its March 2026 annual general meeting.
He also joined the Siemens AG Supervisory Board on February 13, 2025. Siemens had described Schneider at the time of his election as a potential future successor to supervisory-board chairman Jim Hagemann Snabe.
Who is Robert Davis?
The Robert Davis connected with this search is most credibly Robert M. Davis, commonly called Rob Davis, the chairman and CEO of Merck & Co., Inc.
Merck’s current leadership profile states that Davis joined the pharmaceutical company as chief financial officer in 2014. He later became president in April 2021, CEO and a board member on July 1, 2021, and chairman of the board on December 1, 2022.
His career before Merck included senior positions at Baxter, where he served as president of its medical products business and previously held roles including CFO, treasurer and president of the renal business. Before Baxter, Davis spent approximately 14 years at Eli Lilly and Company.
Davis has a bachelor’s degree in finance from Miami University, an MBA from Northwestern University’s Kellogg School of Management and a law degree from Northwestern University Pritzker School of Law.
Is Robert Davis still CEO of Merck?
Yes. Merck’s current leadership page identifies Davis as chairman of the board and chief executive officer, and Merck’s May 2026 annual shareholders meeting also identified him as chairman, president and CEO.
Merck’s 2025 annual filing, published in 2026, likewise identifies Robert M. Davis as chairman, chief executive officer and president.
Davis therefore remains an active corporate CEO, unlike Schneider, whose Nestlé chief executive tenure ended in 2024.

How their careers compare
Schneider and Davis share several broad characteristics, but their career paths are distinct.
Schneider built much of his reputation through corporate finance and health-care management before spending almost eight years leading the world’s largest food and beverage company. His post-Nestlé activities have moved toward board-level governance at companies including Roche and Siemens.
Davis has remained much more closely tied to the pharmaceutical industry. His career includes Eli Lilly, Baxter and Merck, and his present responsibilities center on Merck’s medicines, vaccines, research pipeline and global operations. Merck also lists him as chair of the Pharmaceutical Research and Manufacturers of America board and vice president of the International Federation of Pharmaceutical Manufacturers and Associations.
Their shared American Heart Association CEO Roundtable membership therefore makes sense in a broader leadership context. Schneider brought experience spanning health care, nutrition and global consumer products, while Davis represented one of the world’s major pharmaceutical businesses.
Did Mark Schneider and Robert Davis work together?
There is no verified evidence in their official biographies that Schneider and Davis were colleagues at the same company.
Schneider’s documented executive history includes Haniel Group, Fresenius Medical Care, Fresenius Group and Nestlé, followed by board positions including Roche and Siemens.
Davis’s documented career includes Eli Lilly, Baxter and Merck.
The overlap is therefore best understood as participation in a broader corporate leadership initiative rather than shared employment.
Were they both involved with the American Heart Association?
Yes, and this is the most concrete connection between them.
Mark Schneider was already named among American Heart Association CEO Roundtable members while serving as Nestlé CEO in 2017.
By the November 2023 roster, both Schneider of Nestlé and Davis of Merck appeared in the same membership group.
The AHA describes the Roundtable as a leadership collaborative through which CEOs work on issues such as workplace health, mental health, access to health care, employee well-being and health innovation.
The organization’s current members page continues to list Robert M. Davis of Merck. Schneider is not listed on the current membership page, which is consistent with the fact that he is no longer Nestlé’s CEO, although the AHA does not state on that page why individual former members are absent.
Are Mark Schneider and Robert Davis related?
No credible public record reviewed for this topic identifies Mark Schneider and Robert M. Davis as relatives.
Their different documented career histories also provide no indication of a family relationship. Searches combining their names are better explained by their presence within corporate leadership networks such as the American Heart Association CEO Roundtable.
Is there a business partnership between Mark Schneider and Robert Davis?
No direct partnership between the two executives is documented by Nestlé, Merck, Roche, Siemens or the American Heart Association sources examined here.
Their verified relationship is better described as membership in the same multi-company executive initiative, rather than a bilateral partnership between Schneider and Davis.
Why are Mark Schneider and Robert Davis searched together?
The exact reason behind every search cannot be known, but there is a clear documentary explanation.
The 2023 American Heart Association CEO Roundtable roster contains both executives on the same membership page and even places their entries beside each other. That type of document can cause names to become associated in search indexes, knowledge systems and pages built from corporate leadership data.
Readers should therefore be cautious with pages that imply a deeper connection without supplying evidence.
