Jack in the Box ousts CEO, names Mark King interim leader

Jack in the Box pushed out CEO Lance Tucker and installed board chair Mark King as interim chief executive, a move that signals the company is still very much in turnaround mode as store crews, franchisees and managers brace for more pressure on sales, labor and underperforming locations.

The change was effective immediately on May 13, 2026. King had already been on the board since November 2025 and had served as board chair since March 2026, giving the company a familiar hand at the top while it searches for a permanent leader. Alan Smolinisky was named lead independent director in the same leadership shuffle.

The executive reset came after another weak quarter. Jack in the Box said same-store sales fell 3.8% in the quarter ended April 12, 2026, with franchise same-store sales down 3.9% and company-owned same-store sales down 2.8%. The company also reported diluted earnings per share from continuing operations of $0.65 and operating EPS of $0.76. Management said trends improved into the third quarter, but the latest numbers show a chain still struggling to stabilize traffic and spend.

For restaurant workers, the bigger story is what the turnaround already has in motion. Jack on Track, introduced on April 23, 2025, was pitched as a companywide plan to improve long-term financial performance, strengthen the balance sheet and support an asset-light business model. In a February 2026 investor presentation, the company said Tucker sold Del Taco to reduce debt and refocus on Jack in the Box, reevaluated lease terms and market penetration, and let franchisees close unprofitable locations. The chain has already closed dozens of underperforming restaurants and says it expects to close 150 to 200 more.

That kind of footprint reduction can land hard on the front line. Jack in the Box operates and franchises about 2,135 restaurants across 21 states, so every closure ripples through hours, schedules and job security. For line cooks, cashiers, hosts and shift managers, a tighter turnaround can mean more retraining, heavier pressure on labor targets, stricter attention to speed and waste, and a morale hit when stores disappear or teams are reshuffled. In a business already shaped by staffing shortages, high turnover and uneven pay across the front and back of house, another CEO change raises the same question workers have heard before: whether the next phase brings stability, or just faster restructuring.
