BT Shares Slide as Government Signals Opposition to Stake Increase and Results Weigh on Sentiment

Regulatory resistance to Bharti Enterprises, weak customer trends and an unsettled macro backdrop combine to pressure BT stock

By Marcus Reed

BT Group shares fell sharply amid news that the British government plans to block any attempt by Sunil Bharti Mittal to increase his nearly 25% holding, compounding investor concern after disappointing full-year results and mounting customer losses at Openreach. Broader risk-off market conditions, driven in part by escalating geopolitical tensions and rising oil prices, added to selling pressure on capital-intensive telecom names.

BT Shares Slide as Government Signals Opposition to Stake Increase and Results Weigh on Sentiment

Key Points

  • UK government plans to block any increase in Sunil Bharti Mittal's stake, removing a bullish ownership narrative for BT.
  • BT guided UK service revenues of £15.1-15.4bn for 2026-27 versus £15.4bn reported last year.
  • Openreach lost 825,000 broadband customers in the past year and expects a further 800,000 loss in 2026-27, pressuring service volumes and ARPU dynamics.

BT shares dropped 3.1% in intraday trade, touching a session low of 209.7p, after a politically charged development unsettled investors. Reports that the UK government will oppose any move by Indian billionaire Sunil Bharti Mittal to further increase his stake in the company removed a key source of investor optimism.

Bharti Enterprises currently holds just under a quarter of BT. The conglomerate had previously been viewed as a potential source of confidence for the group, so official resistance to additional accumulation represents a meaningful change to that narrative.

The government announcement intensifies pressure on BT following an already difficult earnings season. The stock experienced a 5% decline the previous Thursday after full-year results were poorly received by the market.

On guidance, BT expects UK service revenues in the 2026-27 year to be in a range of £15.1 billion to £15.4 billion, compared with £15.4 billion reported in the prior year.

Customer metrics in the full-year disclosure were also a concern. BT reported a loss of 825,000 Openreach broadband customers over the year, and management expects to lose a further 800,000 in 2026-27.

Analyst sentiment has been unfavourable. UBS kept a Sell rating on BT Group as recently as May 18.

Macro developments are adding to the company-specific headwinds. On May 28, futures suggested BritainFTSE 100 would open sharply lower, with futures down 0.9%. The pan-European STOXX 600 also fell 0.4% that day, with all major regional bourses lower amid rising US-Iran tensions.

Oil prices climbed more than 2.5% to about $97 a barrel as hostilities escalated and Kuwait intercepted hostile missile and drone threats. That risk-off environment has tended to pressure rate-sensitive, capital-intensive telecom stocks in the region.

The combination of a de facto cap on further share accumulation by the groupshareholder, disappointing revenue and customer trends at Openreach, and a worsening macro backdrop created broad selling pressure in the stock on the day.

Technically, analysts noted the stock was struggling around key moving averages, with daily momentum indicators turning negative and no fresh supportive news to counter the downside. The share price was trading around 210.2p, well below its 52-week peak of 242p, suggesting investors are reassessing how quickly and sustainably BT can execute its turnaround plan.


Summary

BT shares slid after the UK government signalled opposition to any bid by Sunil Bharti Mittal to raise his stake, compounding investor concerns stemming from weak full-year results, significant Openreach customer losses and a risk-off market environment influenced by geopolitical tensions and rising oil prices.

Key points

  • Government opposition to further stake accumulation by Bharti Enterprises - impacts BT shareholder dynamics and investor sentiment.
  • Weak operational results and guidance - UK service revenue guidance of £15.1-15.4bn for 2026-27 versus £15.4bn prior year.
  • Customer attrition at Openreach - a loss of 825,000 customers in the year with a forecasted further loss of 800,000 in 2026-27 - impacts telecom services and broadband market dynamics.

Risks and uncertainties

  • Regulatory and political intervention - government refusal to permit stake increases could limit strategic options and influence investor appetite for telecom equities.
  • Weak revenue and customer trends - continued declines in UK service revenue and Openreach subscribers could put further strain on operating performance.
  • Broader market volatility - geopolitical tensions and rising oil prices are creating a risk-off environment that disproportionately affects rate-sensitive, capital-intensive telecom firms.

Risks

  • Regulatory intervention restricting stake increases could limit strategic transactions and depress investor confidence in the telecom sector.
  • Continued declines in UK service revenue and large Openreach customer attrition could further undermine BT's operating performance and cash flow.
  • Escalating geopolitical tensions and higher oil prices are fostering a risk-off environment that adversely affects rate-sensitive, capital-intensive telecom stocks.
