Asia Telecom Stocks Underperformed Broader Market in April; AI and 6G Become New Drivers

Overview

This report is a monthly review by UBS of the Asia and global telecom industry for April 2026, focusing on sector performance, key drivers, and individual stock dynamics. The report notes that while Asia telecom stocks generally underperformed the broader market, some companies achieved significant outperformance due to AI deployment, regulatory tailwinds, and ARPU recovery. Institutions maintain buy ratings on operators in markets such as Indonesia, Thailand, and Hong Kong, and closely watch structural trends including 5G/6G technology evolution, satellite internet, and enterprise-level AI services. Additionally, the report warns of earnings pressure and regulatory risks facing some North American telecom stocks.

Core views

The Asia telecom sector generally underperformed the market in April, rising 9.7% vs the broader market's 12.3%, but showed clear structural divergence. SK Telecom surged 21.5% due to investor expectations regarding its 0.3% equity stake in Anthropic, while Vodafone Idea rose 20% benefiting from the Indian government's freeze and reduction of its AGR debt. Institutions highlight True Corporation, Telkom Indonesia, Indosat, and HKT Trust as key recommendations, citing continuous improvement in ARPU, stabilized competitive landscapes, and optimized capital expenditures. In India, Bharti Airtel's ARPU growth and expansion in non-mobile businesses (enterprises and data centers) are core highlights. While Vodafone Idea still faces financial risks, regulatory support brings hope. On the technology front, operators are accelerating the deployment of enterprise-level AI services, such as Singtel's AI.dea, Telkom Indonesia's Agentic AI, and PLDT's KAl, aiming to enhance corporate client efficiency. Satellite internet and 5G convergence has become a new trend. T-Mobile partnering with Starlink to launch enterprise "SuperBroadband" services, as well as VEON's Banglalink and Amazon acquiring Globalstar, all point to the commercial potential of D2D (Device-to-Device) services. China launched the world's first pre-6G test network in Nanjing, marking the transition of 6G technology from concept to infrastructure integration. On regulation, the Indian government froze a substantial amount of AGR debt for VIL, alleviating financial pressure. Meanwhile, regulators are exploring policies on open access and spectrum management to foster market competition. In North America, AT&T and Verizon received buy ratings due to accelerated service revenue and EBITDA growth. T-Mobile is also favored for strong financial performance and attractive valuation. In contrast, BT Group's sell rating was maintained due to expected free cash flow below guidance by 2030, highlighting growth bottlenecks faced by developed market operators.

Analysis framework

UBS's analysis adopts a multi-dimensional framework: First, through price-volume decomposition of monthly stock performance and consensus earnings forecasts (NTM/CY2026), identifying outperforming individual stocks and their drivers (e.g., SKT's AI narrative, VIL's regulatory tailwinds). Second, applying transmission logic across the upstream, midstream, and downstream value chain, analyzing how 5G construction, satellite internet, and AI services jointly reshape telecom operator business models, transitioning from traditional connection services to high-value-added digital solutions. Third, via industry concentration analysis, pointing out that in markets like Indonesia and Thailand, competition has shifted from price wars to service and efficiency competition, providing room for profit repair. Finally, using valuation methods (PE/EV/EBITDA) for horizontal comparison of different regional markets, finding that Asia operator valuations are generally lower than North America and Europe, but earnings growth expectations are higher, supporting the judgment of their relative investment value.

Methodology notes

• Industry/Industrial Analysis FrameworkSupply-demand framework

  Slowing supply-side competition, rising demand-side ARPU

  The report believes the core contradiction in the Asia telecom market has shifted from past fierce low-price competition (supply surplus) to the demand side's ARPU (Average Revenue Per User) recovery. Analyzing SIM card pricing data in Indonesia and Thailand, it was found that operators did not significantly lower prices due to holidays but instead maintained prices through personalized plans, indicating that vicious competition on the supply side is easing, creating conditions for profit improvement.

• Industry/Industrial Analysis FrameworkPenetration S-curve

  Inflection point of 5G and satellite internet penetration

  The report views 5G network construction, enterprise-level AI services, and satellite internet (D2D) as new growth curves for the telecom industry. By analyzing events such as T-Mobile's partnership with Starlink, China's pre-6G testing, and Amazon's acquisition of Globalstar, it believes these technologies are moving from the early adoption stage (low penetration) to an inflection point of accelerated popularity, becoming core drivers for the next few years.

• Cyclical and Prosperity FrameworkProsperity Inflection Analysis

  Telecom industry profitability inflection

  By comparing operator historical profitability data with current trends (e.g., Indosat, True Corp's continuous ARPU improvement), the report judges that the Asia telecom industry is recovering from the trough and entering a period of profit repair inflection. This judgment is based on triple evidence of cost control, capital expenditure decline, and ARPU recovery, rather than relying solely on the macroeconomic cycle.

• Valuation MethodPE/PEG valuation

  Valuation comparison based on earnings growth

  When assessing Asia and North American operators, the report not only compares current PE multiples but also focuses on future 2-3 year earnings growth expectations (CAGR), combined with EV/EBITDA indicators, judging that Asia operators have higher growth potential at relatively lower valuations, thus reaching the conclusion of greater attractiveness.

• Macroeconomics FrameworkInterest rate parity

  Impact of interest rate changes on telecom stock cash flow and valuation

  The report analyzes the impact of the interest rate environment on telecom stocks, noting that in a downward interest rate cycle, the discounted value of telecom stocks' free cash flow (FCF) will increase, supporting stock prices. At the same time, a high interest rate environment increases debt costs, putting pressure on financial status. This analysis is based on the basic relationship between interest rates and corporate financing costs.

• Industry/Industrial Analysis FrameworkSubstitution Effect Analysis

  Voice and SMS services replaced by OTTs

  The report explicitly points out that income sources such as traditional voice, SMS, and international calls are continuously being replaced by OTT applications like WeChat and WhatsApp. This is a long-term structural challenge facing the telecom industry, forcing operators to transform towards data and value-added services.

• Company Fundamentals and Financial FrameworkFree cash flow analysis

  Free Cash Flow (FCF) as a core profitability indicator

  When evaluating companies like BT Group and Telstra, the report treats Free Cash Flow (FCF) as a core indicator, believing it is the most important standard for measuring a company's real profitability and dividend capability, rather than simple profits or EBITDA.
