Jack in the Box misses Q1 revenue estimates as sales fall 4.3%; JACK rises after EBITDA outlook

Jack in the Box Inc. (NASDAQ: JACK) reported Q1 2026 revenue below Wall Street expectations, with sales falling 4.3% year over year to $254.3 million. GAAP earnings were $0.53 per share, 23.7% below analyst consensus. Same-store sales declined 3.8% year over year, broadly in line with recent weakness. The company operated 2,128 locations in the quarter, continuing a two-year trend of restaurant closures averaging 6.4% annually. Over the past two years, same-store sales have declined at an average annual rate of 4.2%. Interim CEO Mark King said results “did not meet expectations,” though trends improved into the third quarter. Analysts expect revenue to grow 1.1% over the next 12 months. Despite the earnings and sales miss, Jack in the Box shares rose 2.1% to $13.07 after the report, supported by EBITDA that topped estimates and full-year EBITDA guidance above consensus.
