Kroger's Conduct Crisis: When Ethics Investigations Trump Earnings

Rodney McMullen's fifty-year arc at Kroger—from stock clerk to chief executive—ended not with a farewell tour or a graceful transition, but with an abrupt exit triggered by a board investigation into personal conduct. The investigation, which wrapped in 2024, found McMullen's behavior "inconsistent with Kroger's Policy on Business Ethics," though the board was careful to note the misconduct bore no relation to financial performance, operations, reporting, or any Kroger employees. Translation: whatever happened in McMullen's personal life stayed in McMullen's personal life, but it was incompatible with sitting in the corner office of America's largest supermarket chain.

The resignation left a leadership vacuum at precisely the wrong moment. Kroger's fundamental challenge—convincing inflation-battered consumers that the grocery store is where their money should go—demands steady hands and undivided attention. Instead, the company inherited instability. Other top executives departed in McMullen's wake, suggesting either a broader cultural reckoning or at minimum the kind of organizational uncertainty that talented people tend to exit. The $24.6 billion merger with Albertsons, blocked by federal regulators in 2024, had already knocked the company off its transformational footing. Now Kroger was searching for a CEO while navigating margin compression that would make a private equity firm weep.

Enter Greg Foran, the Walmart veteran whom Kroger appointed as McMullen's successor less than a year after the resignation. Foran arrives with credentials that resonate with Wall Street's view of what grocery retail needs: digital competence and operational discipline. At Walmart U.S., where he spent six years before departing in 2019, Foran championed online ordering and pickup capabilities—the kind of omnichannel muscle that separates winners from Chapter 11 fodder in modern retail. He then led Air New Zealand through a pandemic-era digital transformation, which on paper demonstrates an ability to navigate existential crises without having a very public ethical reckoning.

The market's reaction was unambiguous. Kroger shares climbed as much as 8% on the Foran announcement, a vote of confidence that felt almost defensive. Wall Street was essentially saying: Thank God, a competent person is taking the wheel. Which is another way of saying the previous governance situation was sufficiently dire that mere professional credibility registered as news.

The question lurking beneath the market enthusiasm is the one that always matters most in these situations: what did the board know, and when did they know it? McMullen's conduct investigation didn't materialize overnight. Board investigations into CEO personal conduct typically begin somewhere—a complaint, a pattern, a whistleblower, a moment of institutional discomfort that finally bubbles up to the audit committee. The gap between whatever triggered the investigation and the ultimate resignation is the gap where governance happens or fails.

Kroger's board presumably exercised appropriate oversight by initiating and completing the investigation. But the abruptness of McMullen's exit, combined with the subsequent exodus of other executives, suggests the organization wasn't prepared for the transition. Leadership vacuums don't fill themselves in grocery retail, where the difference between a 2.5% and a 3.2% margin determines whether you're a going concern or a restructuring candidate. The operational challenges don't pause for management transitions. Consumers don't stop eating. Competitors don't stop improving.

Foran inherits a company that needs to prove it can earn consumer loyalty in an inflationary environment where every percentage point of price premium requires trust and consistency. He arrives to a workforce that has witnessed a CEO's abrupt departure for ethical violations and the subsequent departures of multiple senior leaders. He takes the helm of an organization that lost a transformational deal and continues to lose margin share to competitors.

For Foran, the question is whether his Air New Zealand track record in digital transformation and his Walmart experience in omnichannel execution can translate to a grocer in the middle of a governance reset. For Kroger's board, the question is whether appointing a competent external operator addresses the underlying problem: an organization that allowed its long-serving CEO's personal conduct to become incompatible with the job before anyone acted.

Wall Street cheered the appointment because Foran represents professional competence in a moment of institutional doubt. But cheering a new CEO is the easiest thing Wall Street does. Watching him navigate the actual problems—margin compression, consumer skepticism, internal uncertainty, and a board's apparent surprise at discovering the previous CEO was behaving unethically—will be considerably more instructive.
