Apple Inc. has announced a pivotal leadership change as its Chief Operating Officer (COO), Jeff Williams, prepares to step down from the COO role after a distinguished 27-year tenure at the company. The transition will take place later this month, with Sabih Khan, currently Apple’s Senior Vice President of Operations, set to take over the role. Williams will remain at Apple through his retirement later this year, continuing to report to CEO Tim Cook and overseeing the company’s design team as well as its health initiatives, including the Apple Watch.

The End of an Era: Jeff Williams’ Legacy

Jeff Williams first joined Apple in 1998, rising swiftly through the ranks and eventually succeeding Tim Cook as COO after Cook became CEO in 2011. Williams is widely credited with building and refining Apple’s world-class global supply chain, an operational feat that allowed Apple to consistently roll out blockbuster products such as the iPhone, iPad, and Apple Watch at an unprecedented scale and efficiency.

During his tenure, Williams played a key role in maintaining product quality and cost competitiveness, navigating complex manufacturing landscapes across Asia. He was also instrumental in launching the Apple Watch in 2015—a new product category that soon redefined the smartwatch market and positioned Apple as a leader in consumer wearables. In 2019, following the retirement of Apple’s legendary chief designer Jony Ive, Williams led the critical industrial design team, shaping the look and feel of products across Apple’s portfolio.

Apple CEO Tim Cook praised Williams in a recent statement: “Jeff has helped to create one of the most respected global supply chains in the world; launched Apple Watch and overseen its development; architected Apple’s health strategy; and led our world-class design team with great wisdom, heart, and dedication.”

Williams, now 62, cited a desire to spend more time with family and friends as a key reason for his retirement. “June marked my 27th anniversary with Apple, and my 40th in the industry,” he said, calling his time at the company an “incomparable journey” and expressing confidence in the team’s continued success.

Sabih Khan: The Next COO

Sabih Khan, who will assume the COO responsibilities, has a track record of operational excellence, having overseen Apple’s supply chain, manufacturing, product quality, planning, procurement, and order fulfillment since joining the executive team in 2019. Khan’s leadership has been pivotal in navigating disruptions from the global pandemic, geopolitical tensions, and the ongoing complexity of sourcing components from multiple continents.

Born in India, Khan earned his bachelor’s degree from Tufts University and holds a master’s in mechanical engineering from Rensselaer Polytechnic Institute. Before joining Apple’s procurement group in 1995, he worked in engineering and technical leadership roles at GE Plastics. Known for his hands-on approach, Khan famously responded to a major manufacturing problem by immediately flying to China to resolve it personally—a dedication applauded by colleagues, including Tim Cook.

Khan’s promotion comes at a critical time for Apple. The company faces mounting challenges, including the U.S. government’s recent imposition of tariffs on technology imports and increasing pressure to shift more manufacturing out of China and into domestic facilities or other international markets. Apple’s deft handling of these challenges, anchored by a resilient supply chain, remains essential to its continued global leadership.

Apple’s Ongoing Supply Chain Challenges

The leadership shuffle occurs against the backdrop of significant global supply chain pressures. The Biden administration’s latest tariffs on components from countries such as China, Vietnam, and India have complicated Apple’s logistics and procurement strategies. Hardware production, in particular iPhone assembly, relies on a tightly integrated supply network stretching across Southeast Asia, with only a fraction of Apple’s manufacturing currently located in the U.S.

Political pressure to localize production has intensified, with U.S. officials frequently urging Apple to move more assembly and parts sourcing stateside. In 2024, Apple announced plans to increase stateside investment and began assembling select Mac models in Texas. However, global diversification remains the cornerstone of its supply strategy, with new facilities and suppliers added across India, Vietnam, and Mexico to mitigate geopolitical risks.

Apple’s ability to maintain high product quality and reliable delivery timelines, even amid chip shortages, shipping delays, and regulatory shifts, stands as a testament to Williams’ and now Khan’s leadership in operations. The company’s quarterly earnings continue to reflect strong demand for its products; in Q2 2025, Apple reported revenue of $96.3 billion, with iPhone sales accounting for nearly 54% of the total. The success of emerging product lines such as the Apple Watch and AirPods—both deeply reliant on flawless operational execution—further underscores the importance of a smooth leadership transition.

Strategic Implications for Apple’s Future

The change in operational leadership is likely to have broad strategic implications. Williams’ ongoing role in design and health initiatives signals that Apple is doubling down on product innovation, particularly in health technology—an area that has delivered rapid growth and significant consumer interest. Apple’s status in the wearables and health monitoring market was solidified with robust Apple Watch sales, outpacing traditional watchmakers and earning the company a spot atop the global wristwear charts.

Meanwhile, Sabih Khan’s focus on operational resilience will prove crucial as Apple continues to expand into new territories and faces competitors ranging from Samsung and Xiaomi to fast-moving tech startups. Efforts to minimize dependency on single-region suppliers are expected to accelerate, with increased partnerships across India and North America.

Investors and industry analysts are closely watching the transition. In early July, Jefferies upgraded Apple to a ‘Hold’ rating, citing stable management and ongoing demand for flagship products, but also flagged continued uncertainty in global trade and regulatory landscapes.

The Road Ahead

As Apple orchestrates this high-profile leadership handover, the company’s unrivaled reputation for operational excellence will be both tested and reinforced. Jeff Williams leaves behind a legacy of perseverance through transformational change, while Sabih Khan steps into the COO role with challenges and opportunities alike.

For Apple, the next chapter will be shaped by the continuing evolution of its global supply network, tightening regulatory environments, and unyielding consumer expectations. With the combined experience of Williams, Khan, and CEO Tim Cook at the helm, Apple aims to remain at the forefront of technological innovation, supply chain mastery, and product design—continuing to set the gold standard for the world’s most valuable company.
