Brian Niccol

Taco Bell (2011–2018)

In October 2011, Taco Bell named Niccol their new chief marketing and innovation officer. Niccol joined Taco Bell during a time when sales had stagnated. The brand had spent millions of dollars to fight a class action lawsuit regarding the quality of its beef. While the lawsuit was dismissed, Taco Bell sales dropped 5% in Q2 2011, which the company attributed to damaged consumer perceptions of its food. In January 2012, the brand introduced a breakfast menu, as well as a more upscale "Cantina Bell" menu to compete against fast-casual restaurants like Chipotle Mexican Grill. These plans helped reverse Taco Bell's fortunes, with the company posting an 8% increase in fiscal year 2012.

On January 1, 2015, Niccol was promoted to chief executive officer (CEO) of Taco Bell. He presented an ongoing plan for Taco Bell to be appealing to Millennials and future generations. Niccol led a successful turnaround effort at Taco Bell as CEO.

Chipotle Mexican Grill (2018–2024)

In March 2018, Niccol became the CEO of Chipotle Mexican Grill, replacing founder Steve Ells. Prior to Niccol's arrival, Chipotle had been facing a string of food safety issues beginning in 2015 that had damaged customer trust. The restaurant chain had also tried introducing new items like a queso to mixed reception. In June 2018, Chipotle announced that they were closing up to 65 locations that year. However, Chipotle faced another food safety setback when an outbreak of Clostridium perfringens at a location in Ohio made over 600 people sick in July 2018. In response, Niccol introduced a marketing campaign in September of that year aimed at reminding customers of the restaurant's fresh ingredients and preparation. He credited the advertisements for helping to improve sales.

Although Niccol had moved west to Newport Beach, California to join Taco Bell, he did not move back east to Denver when he joined Chipotle. Rather, under his leadership, Chipotle moved its headquarters from Denver to Newport Beach. During his tenure, he helped double Chipotle's revenue while its profits increased almost seven times. The stock price of Chipotle has increased by almost eight times under Niccol. Niccol also increased salaries for Chipotle's retail staff and expanded employee benefits.

In 2023, Niccol's total compensation at Chipotle was $22.5 million.

Starbucks (2024–)

On August 13, 2024, Niccol was named the incoming chairman and chief executive officer of Starbucks. Niccol replaced Mellody Hobson as the chairman and Laxman Narasimhan as the CEO. On the day of the announcement, shares of Starbucks gained 24.5%. Niccol received a starting salary of $1.6 million and a $10 million starting bonus, with an additional $75 million in equity grants designed to pay out over time and an annual cash incentive opportunity at a target of 225 percent of his base salary. Overall Niccol received $97.8 million in total compensation in 2024, equivalent to 6,666 times the median employee pay at Starbucks for that year.

At the outset of his tenure as CEO, Niccol developed and started implementing a "Back to Starbucks" plan. This included the potential for a doubling of Starbucks's store count in the US. In the fiscal second quarter Starbucks's operating margin fell to 6.9% from 12.8% as expenditure swelled on the turnaround plan. Niccol refused to move the company's headquarters from Starbucks Center in Seattle to a location closer to his residence in Orange County, California. This was disappointing for Starbucks investors who had hoped that a move would revitalize the company by enabling it to draw upon the much larger Southern California talent market for its headquarters staff, as had occurred at Chipotle.

The ongoing 2025 Starbucks workers' strike started under Niccol's tenure as CEO, amid accusations of unfair labor practices and stalling contract negotiations.
