Carl Douglas McMillon (born October 17, 1966), known as Doug McMillon, is an American business executive who served as the president and chief executive officer (CEO) of Walmart, Inc. from February 2014 to January 2026. His tenure at the helm of the world's largest company by revenue spanned nearly twelve years, during which he oversaw Walmart's transformation from a traditional brick-and-mortar retailer into a major e-commerce competitor. McMillon's career at Walmart began in the summer of 1984, when he was a seventeen-year-old high school student unloading trailers at a company warehouse. Over the course of a four-decade career, he rose through multiple divisions of the company, leading Sam's Club as its president and CEO from 2005 to 2009 and heading Walmart International from 2009 to 2013, before being named to Walmart's top position. Upon his retirement in January 2026, McMillon was succeeded by John Furner, with McMillon remaining on Walmart's board of directors.

Early Life

Carl Douglas McMillon was born on October 17, 1966, in Memphis, Tennessee. He grew up in a family connected to Walmart; his father was a dentist who also had ties to the company's operations in Arkansas.

McMillon's introduction to Walmart came during the summer of 1984, when he was seventeen years old. He joined the company as a summer associate, working in one of Walmart's distribution warehouses where his primary responsibility was unloading delivery trailers. This early experience in the company's logistics operations gave McMillon a ground-level understanding of Walmart's supply chain, an area that would remain central to his strategic focus throughout his career. The summer warehouse job was McMillon's first exposure to the scale and operational complexity of the retail business, and he returned to the company after completing his education.

McMillon has spoken publicly about the formative nature of these early years. In a 2026 interview with Fortune, he reflected on the trajectory from unloading trailers as a teenager to leading the entire corporation, describing a career that was built over four decades of incremental advancement through the company's various divisions and leadership roles.

Education

McMillon attended the University of Arkansas, where he earned a Bachelor of Science degree. He later completed a Master of Business Administration (MBA) at the University of Tulsa. His choice of the University of Arkansas was consistent with Walmart's deep roots in the state, where the company was founded and maintains its headquarters in Bentonville. The MBA from the University of Tulsa provided McMillon with a formal grounding in business strategy and management that complemented his practical, operations-based experience within Walmart's warehouse and retail divisions.

Career

Early Career at Walmart

After his initial summer work as a teenager, McMillon rejoined Walmart and began a steady ascent through the company's ranks. His career path took him through various operational and management roles across multiple Walmart divisions, giving him broad exposure to the company's domestic and international businesses. McMillon held positions in buying, merchandising, and general management, progressively taking on larger responsibilities.

His progression through the company reflected a pattern common among Walmart's senior leadership, in which executives are expected to have direct experience with store operations and supply chain management before moving into corporate strategy roles. McMillon's tenure across different functional areas positioned him as a well-rounded executive with knowledge spanning logistics, merchandising, and international retail operations.

President and CEO of Sam's Club (2005–2009)

In 2005, McMillon was appointed president and CEO of Sam's Club, Walmart's membership-based warehouse club division. The role gave him responsibility for one of the company's major business segments, overseeing hundreds of warehouse club locations across the United States.

During his four-year tenure at Sam's Club, McMillon led efforts to refine the division's merchandising strategy and membership value proposition. The warehouse club business model, which relies on annual membership fees and high-volume, low-margin sales, required a different operational approach than Walmart's traditional discount stores. McMillon's leadership at Sam's Club demonstrated his ability to manage a large-scale retail operation with its own distinct customer base and competitive dynamics, separate from but complementary to the broader Walmart enterprise.

President and CEO of Walmart International (2009–2013)

In 2009, McMillon moved from Sam's Club to become president and CEO of Walmart International, the company's division overseeing all operations outside the United States. This was a significantly larger and more complex portfolio, encompassing retail operations across multiple continents, including markets in Latin America, Asia, Europe, and Africa.

Leading Walmart International exposed McMillon to the challenges of operating retail businesses across diverse regulatory environments, cultural contexts, and competitive landscapes. The international division during this period accounted for a substantial and growing portion of Walmart's total revenue, making it a critical component of the company's overall strategy. McMillon's successful stewardship of the international portfolio from 2009 to 2013 positioned him as one of the leading candidates to succeed Mike Duke as Walmart's top executive.

CEO of Walmart (2014–2026)

On November 25, 2013, Walmart announced that McMillon would succeed Mike Duke as president and CEO, effective February 1, 2014. At forty-seven years of age, McMillon became one of the younger CEOs in the company's history and, notably, someone who had started at the very bottom of the organization as a summer warehouse worker. The Financial Times reported on the succession, noting McMillon's extensive internal experience and the continuity it represented for the company.

E-Commerce Transformation

One of the defining strategic priorities of McMillon's tenure as CEO was the transformation of Walmart into a major e-commerce player. When he assumed the role in 2014, the company faced growing competition from Amazon and other online retailers. Walmart's online sales, while substantial in absolute terms, lagged behind those of its primary digital competitor. In June 2015, The New York Times reported that Walmart was "strengthening e-commerce" efforts as it worked to close the gap with Amazon in online retail.

Under McMillon's leadership, Walmart invested heavily in its digital infrastructure, including the expansion of online grocery pickup and delivery services, the development of its e-commerce platform, and the integration of its physical store network with digital ordering systems. By the time of his retirement, Retail Dive described McMillon's technology and e-commerce investments as a lasting legacy, noting that the company had undergone "a decade of change" under his leadership.

Investments in Labor and Wages

McMillon's tenure also included significant investments in Walmart's workforce. In October 2015, The New York Times reported that McMillon publicly defended the company's investments in labor, stores, and web operations during a period when Walmart's stock was under pressure. The investments in higher wages and improved employee training represented a shift in the company's approach to labor costs, which had historically been a subject of public criticism.

The wage increases and workforce investments came at a cost to short-term profitability. Business Insider reported in November 2015 that Walmart's stock performance reflected investor concerns about the spending levels. McMillon maintained that the investments were necessary for the company's long-term competitiveness, arguing that better-paid and better-trained employees would deliver improved customer service and operational performance.

Social Issues and Public Engagement

McMillon drew attention for engaging publicly on social issues during his tenure, a departure from the more reserved posture traditionally adopted by Walmart's leadership. In June 2015, Crain's Chicago Business reported on McMillon's decision to speak out on social issues, noting that the CEO saw "a chance to make a difference." Bloomberg News similarly reported that McMillon expressed a belief that the company could use its position to address broader societal concerns.

This willingness to address topics beyond the company's immediate business operations marked a notable evolution in Walmart's corporate posture. McMillon's public statements on social matters were covered extensively in the business press and positioned him as a CEO willing to engage with contentious issues.

Sustainability and Operations

McMillon oversaw several operational initiatives during his time as CEO. In 2014, Walmart announced plans for a major transition to LED lighting across its supercenter locations globally, a move aimed at reducing energy consumption and operational costs.

Attracting Higher-Income Shoppers

By the later years of McMillon's tenure, Walmart had expanded its customer base beyond its traditional value-focused demographic. Fox Business reported in early 2026 that Walmart was attracting more higher-income shoppers, a trend that accelerated during periods of elevated inflation when consumers across income levels sought lower prices. This broadening of Walmart's customer base represented a strategic achievement under McMillon, as it suggested the company had improved its appeal across multiple market segments.

Retirement and Succession

On November 14, 2025, Walmart announced that McMillon would retire as CEO in January 2026, after nearly twelve years in the position. CNBC reported that McMillon had overseen the company's transformation into "an e-commerce behemoth" during his tenure. His successor, John Furner, had previously served as president and CEO of Walmart U.S.

In a post-retirement interview with Inc.com, McMillon stated that Furner was "better suited" for the next phase of the company's development, a remark that drew attention for its candor and humility. McMillon also reflected on his career in an extensive interview with the Harvard Business Review, which described Walmart under his leadership as "the world's biggest company in revenue terms."

In a separate interview with WWD, McMillon looked back on his twelve years as CEO, discussing the challenges of leading transformation at such a large organization and the process of reshaping the retail giant's strategy and operations.

McMillon remained on Walmart's board of directors following his departure from the CEO role.

Personal Life

McMillon is married to Shelley McMillon. The couple has two children. McMillon has maintained a relatively low public profile regarding his personal life, consistent with the corporate culture at Walmart, which has historically emphasized operational substance over executive celebrity.

In a 2026 interview with Fortune, McMillon offered advice to younger workers entering the job market, stating that "life is too short" to remain in a job one dislikes and encouraging members of Generation Z to find work that "does not feel" like an obligation. He also gave career advice in an earlier 2010 interview with USA Today, during his time leading Walmart International.

Legacy

McMillon's nearly twelve-year tenure as Walmart CEO is characterized primarily by the company's strategic pivot toward e-commerce and digital integration. When he assumed the role in 2014, Walmart's online capabilities were widely seen as trailing those of major competitors; by the time of his retirement, the company had built a significant digital retail operation and had integrated its physical store footprint with online ordering, pickup, and delivery services. Retail Dive described McMillon's technology and e-commerce efforts as a lasting legacy that fundamentally changed the company.

His investments in employee wages and working conditions represented another significant dimension of his leadership. By raising wages and investing in worker training, McMillon attempted to address longstanding criticisms of Walmart's labor practices while arguing that such expenditures would produce returns in the form of improved customer service and reduced employee turnover.

McMillon's career arc — from teenage warehouse worker to CEO of the world's largest company by revenue — has been cited in business media as an example of internal promotion and long-term career development within a single organization. The Harvard Business Review featured McMillon in a major interview upon his departure, reflecting the significance attributed to his leadership of a corporation with more than two million employees and operations spanning multiple countries.

His willingness to engage publicly on social issues marked a shift in the corporate posture of Walmart and contributed to a broader trend among large American corporations in which CEOs increasingly weighed in on societal matters beyond their immediate business operations.
