BT Group stands on the precipice of exiting the premium sports broadcasting arena after 12 years, with advanced negotiations underway to sell its 50% stake in TNT Sports to joint venture partner Warner Bros. Discovery (WBD). This £750+ million transaction – expected to coincide with BT’s FY2025 earnings announcement – marks a pivotal strategic realignment for both companies. For BT, it concludes a costly experiment in content-driven customer acquisition, while WBD gains full control of critical sports rights to fuel its European streaming ambitions[1][3][6].
Anatomy of a Decade-Long Sports Bet
From Broadband Bundles to Billion-Dollar Rights
BT’s foray into sports broadcasting began in 2013 with the launch of BT Sport, a £2.5 billion gamble to differentiate its broadband offerings through exclusive Premier League and UEFA Champions League rights[10][14]. Early bundling strategies showed promise – 4 million households gained access via BT broadband or Virgin Media partnerships by 2015[9]. However, the economics of premium sports rights soon overwhelmed customer acquisition benefits. By FY2024, TNT Sports reported a £187.5 million pre-tax loss despite £1.15 billion in revenue, with rights costs consuming 68% of income[11][20].
Metric | 2015 | 2020 | 2024 |
---|---|---|---|
Annual Rights Spend | £960M | £1.2B | £1.4B* |
Operating Margin | -12% | -9% | -16.3% |
Subsidized Bundles | 38% of broadband base | 29% of broadband base | 17% of broadband base |

The Discovery Partnership: A Halfway House Exit
BT’s 2022 joint venture with WBD created temporary relief through a £93 million upfront payment and £540 million earn-out structure[5][7]. However, the agreement contained a critical poison pill – WBD’s call option to acquire BT’s stake before 2026 at predetermined terms[7][13]. With TNT Sports’ losses widening 155% year-over-year in 2024[11], CEO Allison Kirkby accelerated divestment plans to refocus on BT’s £15 billion fiber and 5G rollout[3][16].
Warner Bros. Discovery’s Endgame
Streaming Calculus: Sports as HBO Max Anchor
WBD’s acquisition secures exclusive rights to Premier League, UEFA Champions League, and Olympic Winter Games 2026 content – critical differentiators for its HBO Max streaming launch targeting 12 million UK subscribers by 2027[2][6]. Integration with Eurosport UK’s cycling and winter sports portfolio creates a £2.1 billion rights library, enabling tiered pricing:

Synergy Realization Challenges
While WBD anticipates £300 million in annual cost synergies through production consolidation, analysts caution about integration risks:
“Merging TNT’s 11.2 million linear subscribers with Discovery+’s 4.3 million UK streaming base requires delicate content curation. Over-indexing on sports could alienate lifestyle audiences.”

Industry Implications: The New Content Arms Race
Telecoms Retreat, Streamers Advance
BT’s exit mirrors a broader European trend of telcos divesting media assets to fund network upgrades. Vodafone sold its TV platforms in 2023, while Deutsche Telekom reduced its Paramount+ stake. Conversely, WBD’s move signals streamers’ renewed focus on live sports – Amazon Prime Video now holds 22% of Europe’s premium sports rights, up from 9% in 2020[12][15].
Regulatory Hurdles on the Horizon
The UK Competition and Markets Authority (CMA) may scrutinize WBD’s post-acquisition 38% share of live sports broadcasting. Precedents suggest remedies could include:
- Mandatory sublicensing of 15-20% Premier League rights
- Divestment of niche sports properties (e.g., MotoGP)
- Price caps on wholesale distribution to Sky/Virgin Media[6][12]
Path Forward: Execution Risks and Opportunities
BT’s Capital Reallocation Strategy
The stake sale’s proceeds (£600-750 million estimated) will bolster BT’s £5 billion Project AltNet fiber expansion. However, JV wind-down costs could reach £85 million, including:
Cost Category | Estimate (£M) |
---|---|
Staff Redundancies | 42 |
Contract Exits | 23 |
Technology Migration | 20 |

WBD’s Make-or-Break 2026 Timeline
Success hinges on hitting three Q2 2026 milestones:
- HBO Max UK launch with integrated TNT Sports content
- 15% reduction in per-subscriber content costs through AI-driven personalization
- Securing 2027-2030 Premier League rights before November 2026 auction[6][12]
Conclusion: A Bellwether for Converged Media Strategies
This transaction exemplifies the unraveling of telcos’ content ambitions in the face of streaming’s second wave. For BT, it’s a return to infrastructure-first pragmatism. For WBD, the test is whether £2.1 billion in sports rights can translate to streaming profitability where previous entertainment-focused models failed. The outcome will shape investment decisions across both industries through the decade’s end.
