BT Group Plc forecast declining revenues for 2027 that missed analyst estimates, as Chief Executive Officer Allison Kirkby continues a turnaround plan to stem customer losses and fend off growing competition. The warning underscores the mounting pressure facing Britain's largest telecommunications provider as rivals intensify their challenge for residential and business subscribers.

Kirkby inherited a company grappling with eroding market share in a sector where new entrants and aggressive pricing from established players have intensified rivalry. The revenue decline projection suggests BT's efforts to retain customers have yet to produce meaningful results, leaving the company vulnerable to further margin compression in its core fixed-line and mobile operations.

The forecast represents a significant setback for BT's strategic overhaul, which aims to revitalize the group's competitive position while managing heavy investments in fiber network expansion. Investors will closely monitor whether Kirkby's turnaround initiatives can reverse the trajectory before the 2027 target year arrives.
