Investor-specific impacts and likely areas of influence:

• Bharti Airtel Limited (25.40% as of 5 Dec 2025)
  • Leverage: Largest single-block holder - can block special resolutions requiring a 75% majority when aligned with other large holders.
  • Operational: Enables cross-border product bundling, roaming and wholesale capacity agreements, and potential co-investment in emerging markets (notably South Asia and Africa).
  • Strategic risk: A large strategic stake can steer BT towards international mobile and wholesale growth strategies, and influences CEO/board appointments if активно engaged.
• Deutsche Telekom AG (12.22% as of 3 Nov 2025)
  • Technology collaboration: Facilitates R&D and network-sharing discussions (5G/FTTP), and informs BT's mobile strategy given DT's scale.
  • Voting alignment: Can form a strategic bloc with Bharti on telecom-specific initiatives, affecting capital allocation to network CapEx.
• BlackRock, Inc. (3.55% as of 3 Nov 2025)
  • Governance muscle: As a large global asset manager, BlackRock's votes and stewardship letters influence executive pay, climate and ESG disclosures, and board refreshment.
  • Market signaling: Changes in BlackRock's holdings can prompt stock price movement due to ETF/index fund flows.
• The Vanguard Group, Inc. (3.04% as of 3 Nov 2025)
  • Passive but pivotal: Likely to vote conservatively on governance issues; less activist engagement but important in close votes.
• T. Rowe Price Group, Inc. (2.38% as of 3 Nov 2025)
  • Growth emphasis: May push for strategies that enhance long-term revenue and EBITDA growth (e.g., higher mobile ARPU initiatives, fiber rollouts, enterprise services).
• UBS Asset Management AG (1.92% as of 3 Nov 2025)
  • Stewardship: Adds institutional oversight on sustainability reporting, capital allocation and risk management via proxy voting.

Implications for BT's capital and strategic decisions:

• Board and governance: With large strategic shareholders present, board composition and CEO accountability are areas where shareholder preferences will carry weight.
• Capital allocation: Institutional investors balance dividend and buyback expectations against heavy network CapEx; strategic shareholders may prefer reinvestment for international growth.
• M&A and partnerships: Bharti and Deutsche Telekom stakes increase the probability of joint ventures, spectrum-sharing deals, and cross-border commercial agreements rather than outright disposals.
• Market perception: Reporting by BlackRock, Vanguard, T. Rowe Price and UBS means changes in BT's ESG and financial metrics are quickly reflected in index funds and institutional flows, affecting liquidity and valuation multiples.
