JD Wetherspoon Plc issues a third profit warning in 2026 after costs rise faster than expected, affecting earnings at its pub chain. Bloomberg and The Guardian report that the company signals it may miss profit expectations, pointing to continuing pressure across UK hospitality. The Guardian says the chair, Tim Martin, tells investors that substantial increases in costs are being felt, including higher bills for energy, food and labour, as well as tax-related costs. The reports characterize the warnings as part of a broader strain on the hospitality sector, where operator margins are under pressure from elevated operating expenses. Bloomberg adds that the latest warning comes after earlier profit alerts during the year, making it the third warning in 2026. The company’s guidance and financial outlook are not detailed in the provided summaries, but both outlets emphasize the same core issue: higher costs are eroding pub earnings.
