Satellite communications threat manageable in the near term; HSBC maintains preference for TMUS

Overview

This report assesses the impact of SpaceX/Starlink's connectivity business expansion on the US telecom industry. HSBC believes Starlink has growth potential in spectrum, satellite capacity, and enterprise connectivity, but its entry into mass-market mobile communications remains constrained by technical capabilities, satellite launch cadence, terrestrial deployment, customer distribution, relative pricing, and regulatory requirements.

Core views

Starlink's current key growth sources are enterprise businesses, including government contracts, aviation, and cruise connectivity services, and it does not fully compete with the core services of traditional US telecom operators in the near term. US telecom operators' earnings fundamentals are expected to remain resilient, with risks skewed more toward market sentiment than near-term performance. HSBC continues to rank TMUS as its preferred US telecom stock, while maintaining a Hold view on SPCX, which has a high valuation and relies on numerous long-term assumptions.

Analysis framework

The report uses bottom-up serviceable obtainable market estimates to adjust Starlink's market size derived from weighted-average ARPU, and assesses its competitive impact on traditional telecom operators by incorporating population and geographic exclusions, income affordability, pricing comparisons, satellite and terrestrial network performance, regulatory access, and deployment progress.

Methodology notes

• Market sizingTAM and SOM analysis

  Total addressable market and serviceable obtainable market

  Compares the company's disclosed TAM with HSBC's estimated serviceable obtainable market, incorporating geographic, income, technology, and pricing constraints.

• Valuation methodsSum-of-the-parts valuation (SOTP)

  Segment-based valuation

  The report evaluates SpaceX's space, connectivity, and artificial intelligence businesses separately and applies probability weightings to long-term business opportunities.

• Competitive analysisRelative pricing and network capability comparison

  Competitiveness of satellite versus terrestrial networks

  Compares Starlink with traditional telecom offerings in pricing, coverage, capacity, latency, and customer switching conditions to assess the feasibility of mass-market substitution.

Asset mapping & comparison

Structured mapping from thesis to named assets (strengths, weaknesses, peers, risks).

• T-Mobile US, Inc. (TMUS)

  Preferred stock in the US telecom sector

  Strengths

  HSBC believes its earnings resilience is relatively strong, while traditional operators have deep experience in capacity management, product portfolios, promotions, and customer retention.

  Weaknesses

  It may continue to be affected by satellite communications substitution narratives and market sentiment.

  Comparison

  Starlink's current enterprise business has limited direct competition with TMUS's core business; homogeneous competition in mass-market mobile communications still requires Starlink to resolve capacity, channel, and terrestrial deployment issues.

  Risks

  Earlier-than-expected scaling of V3 satellites, rapid rollout of Starlink terrestrial networks, lower pricing, or changes in partnership models could all intensify competition.

• SpaceX (SPCX)

  Satellite connectivity expansion leader

  Strengths

  It has the Starlink network, EchoStar spectrum resources, government and enterprise connectivity opportunities, and potential growth use cases including aviation, maritime, and connected vehicles.

  Weaknesses

  Consumer market size assumptions are aggressive; satellite launches, terrestrial deployment, channel development, pricing competitiveness, and regulatory approvals all face constraints.

  Comparison

  Satellite connectivity is suitable for remote areas, backup connectivity, and specific enterprise scenarios, but is unlikely to fully replace terrestrial networks in mass-market communications in dense cities in the near term.

  Risks

  Weaker-than-expected pricing power, regulatory restrictions, obstacles to spectrum acquisition, delays in V3 deployment, and high capital expenditure.

Key data

• HSBC estimate of consumer broadband and mobile SOMUSD105-310bn78%-92% below the company's implied TAM.
• Consumer broadband SOMUSD40-120bnCompared with company TAM of USD660bn.
• Mobile communications SOMUSD60-185bnCompared with company TAM of USD740bn.
• Starlink global consumer connectivity customersApproximately 12 millionThe report believes significant expansion of the distribution network is still required to compete with traditional operators in the United States.
• V3 satellite critical scale targetApproximately 1,000 satellites, target Q2-2027HSBC believes Starship's launch cadence and commercialization capability have not yet been sufficiently validated.
• Starlink fixed broadband coverage164 markets, 3.3 billion peopleMobile services currently cover 12 countries, with a further 19 countries expected to launch later.
• SPCX disclosed share price and target priceUSD133.29 / USD117Corresponds to a Hold rating.

Impact & implications

For US telecom stocks, Starlink's expansion will continue to create substitution risks at the valuation and sentiment levels, especially in underserved, rural, and high-ARPU markets; however, fiber and 4G/5G retain structural advantages in economics and performance in core urban and suburban areas. Competitive risks could rise if V3 deployment, terrestrial spectrum networks, or partnerships with operators advance materially faster than expected.

Risks

• The time for V3 satellites to reach critical capacity is later than management expects.
• Insufficient Starship commercialization and launch frequency constrain satellite deployment speed.
• Starlink pricing is 1.4-3.5 times higher than terrestrial broadband in many countries, while mobile pricing is 2.3-24.3 times higher, weakening mass-market penetration.
• Spectrum, landing rights, licensing, and local data regulatory requirements across countries may delay expansion.
• If technology upgrades materially improve urban network performance, or smaller operators actively partner with Starlink, its market opportunity could exceed HSBC's estimates.
• Traditional telecom operators may face valuation and sentiment pressure due to expectations of satellite substitution.

What to watch

• V3 satellite launch cadence, Starship commercialization progress, and the critical capacity target for Q2-2027.
• Starlink mobile service launch timing, and the cost and progress of terrestrial spectrum network deployment.
• Starlink's wholesale, partnership, or competitive arrangements with US operators.
• Distribution channels, pricing plans, and customer-acquisition strategy for consumer phone services.
• Changes in the growth mix between enterprise and consumer revenue.
• Local US regulation and spectrum and licensing approvals in other countries.
