‌Market and Competitive Environment

In FY25, the Thai economy operated in a challenging environment amid global uncertainties and trade tensions, alongside domestic factors that continued to weigh on consumer sentiment. While government support measures and temporary export tailwinds provided some support, overall economic conditions remained pressured.

The mobile industry maintained positive momentum, supported by sustained customer demand for reliable, high-quality connectivity, driving data usage growth and ongoing 5G adoption, alongside demand for value-added services such as premium sports content. Stricter SIM registration requirements further enhanced user security and raised overall industry standards. Competition remained centered on value-based and personalized offerings to address evolving digital needs.

The fixed-broadband industry continued to expand, driven by rising household connectivity demand and increasing adoption of innovative products and entertainment. Demand increasingly reflected the adoption of higher-speed broadband, bundled content, smart routers, and IoT-based services that enhanced the in-home digital experience. In FY25, competitive dynamics moved beyond pure connectivity, with operators emphasizing product innovation and network reliability.

The enterprise segment benefited from accelerating digital transformation among Thai corporates, together with ongoing investments by global OTT and big-tech players. These trends sustained demand for enterprise connectivity, cloud services, and data-center solutions.

The IT retail industry delivered solid growth in FY25, supported by device upgrade cycles and accelerated purchasing amid concerns over potential increases in device prices related to tax tariffs. Demand was observed across both premium and entry-level segments, with higher unit sales and increased 5G smartphone penetration. The launch of the iPhone 17 further supported market demand and helped sustain sales momentum.

Core service revenue guidance to be around 3-5% focusing on quality growth and an exceptional user experience

In 2026, core service revenue is expected to grow by approximately 3-5%, outpacing Thailand's GDP, supported by continued expansion of the digital economy. While the macroeconomic environment remains cautious amid global geopolitical risks, trade frictions, and softer consumer sentiment, AIS will continue to focus on disciplined execution, quality growth, and delivering an exceptional user experience. Structural tailwinds from rising mobile and fixed-broadband data usage, together with ongoing digital transformation across consumer and enterprise segments, continue to underpin growth. Revenue expansion will be driven by sustained connectivity demand, ARPU uplift, and the rollout of value-added digital services.

In the B2C segment, growth will be supported by rising connectivity demand, higher data consumption, and deeper penetration across mobile and home broadband services. AIS will continue to enhance ARPU through personalized offerings, premium digital, entertainment, and sports content via global partnerships, as well as expanded services beyond basic connectivity. These include smart-home solutions, IoT connectivity, AI-enabled cloud services for home and small-office use, and premium content delivered through the AIS Playbox platform, reinforcing customer engagement and revenue resilience.

In the B2B segment, growth is expected to be driven by accelerating demand for Enterprise Data Services (EDS), cloud solutions, and domestic and international data-center services. This momentum is supported by ongoing digital transformation across enterprises, increasing adoption of 5G-enabled use cases, and continued innovation in connectivity, cloud, and digital infrastructure solutions, positioning AIS as a trusted partner for enterprise digitalization.

EBITDA to growth around 2-4% broadly tracking revenue growth, as the Company prioritizes spending to build a foundation for long-term growth

EBITDA growth will be supported by revenue and device sales margin expansion. With a focus on sustaining long-term growth and competitiveness, AIS continues to invest in network and IT modernization, and selectively in content, aimed at enhancing digital capabilities, scalability, and elevating customer experience, which may moderate near-term margin expansion.

In addition, strategic investments in virtual banking among others are expected to establish new growth platforms and diversify future earnings beyond traditional connectivity services, although they may exert pressure on EBITDA in the early stages. AIS expects virtual bank to become profitable in year 4 onwards.

CAPEX is at approx. 30-35bn to sustain network quality leadership in line with increasing demand in connectivity and to build foundation for sustainable medium-term growth.

The CAPEX reflects a new investment phase aligned with anticipated growth in data consumption and long-term network quality leadership, with YoY increase primarily reflecting higher mobile network investment. Spending will focus on expanding network capacity and coverage to support continued growth in 5G and broadband usage, and accommodate rising traffic demand. Network modernization is expected to support customer stickiness and ARPU resilience.

In parallel, investment in core IT systems, including application rationalization, will improve operating efficiency, service agility, and long-term scalability, aiming to build solid digital foundation and improve customer experience.

The planned CAPEX allocation broadly comprising approximately 55-60% mobile, around 20% broadband, approximately 10% enterprise, and around 15% IT and others. Over the medium term, CAPEX is expected to remain around 15% of total revenue.

Dividend policy at minimum 70% of net profit

AIS is committed to driving long-term growth while delivering returns to shareholders. We place importance on maintaining strong financial health and flexibility to pursue future growth. Our dividend policy is to pay a minimum of 70% of net profit. By preserving cash flow, we ensure that we have the financial flexibility to lead, compete, and pursue growth prospects in any changing circumstances.

The dividend payment shall be made twice a year and is based on consolidated earnings and subjected to the availability of retained earnings on the separate financial statements. In all cases, dividend payment shall depend on cash flow and investment plan including any other future obligations of the Company and/or subsidiaries. Such dividends shall not adversely affect the Company and its subsidiaries' ongoing operations.

‌Recent development in Sustainability

Decarbonization Project Implementation

In 2025, the Board of Directors approved a new target to reduce GHG emissions intensity (Scope 1 and Scope 2) per unit of data traffic by 25% by 2030 (using 2024 as a baseline), following the achievement in GHG emission reduction in 2024 by 90% (from baseline 2015).

To support this goal, AIS has launched

Decarbonization Implementation starting in 2025.

The initiative focuses on three key areas.

  1. Improving energy efficiency through smart cooling systems, inverter air conditioners, LED lighting, and consolidating 3BB network equipment.

  2. Switching to cleaner transport by replacing vehicles with EVs, hybrids, and using e-forklifts.

  3. Expanding renewable energy use by installing solar panels and sourcing green power.

These initiatives support AIS's goal to cut carbon emissions and operate more sustainably.

AIS ID: Mobile Identity Authentication Service

In November 2025, AIS launched "AIS ID" in collaboration with ETDA and the NBTC, introducing Thailand's first Mobile ID service in the telecom sector. The service allows customers to verify their identity for online transactions using their mobile number, with liveness detection technology to enhance security and prevent fraud, in line with national regulatory standards.

1185 Scam SMS Reporting Service



In October 2025, AIS launched the "1185 Snap & Share" service to enhance customer cyber safety. The service allows users to report scam SMS messages by simply sending a screenshot to SMS number 1185. AIS will verify and block fraudulent senders within 24 hours to prevent further scams. The service is free and unlimited for all AIS customers.

191 Emergency Location Service

In August 2025, in collaboration with the Metropolitan Police Bureau, AIS announced the launch of Thailand's first "191 Emergency Location Service (191 ELS)", enabling automatic caller location identification for Android users on the AIS network without additional apps. Using Advanced Mobile Location (AML) technology, the system transmits the caller's location directly to emergency centers, enhancing accuracy, response time, and public safety through AIS's intelligent network.

Waste Management

Aligned with Target

Achieved (in 2025)

1 Rationale of current Climate Action target :

  • AIS main GHG emissions come from electricity use across network towers and data facilities, making utility-related emissions (Scope 2) the dominant source.

  • Structural Limitations in Thailand's Electricity Decarbonization Mechanisms

    • Power Purchase Agreements (PPAs): Corporate PPAs are not yet legally permissible in Thailand. As such, AIS cannot directly procure renewable electricity from independent producers-a key instrument typically used by global peers to achieve near-term decarbonization.

    • Renewable Energy Certificates (RECs): The Thai REC market faces double-counting issues, as renewable power fed into the national grid remains in the Grid Emission Factor (GEF) while producers issue RECs to corporate buyers. This leads to the same GHG reduction being claimed twice, conflicting with the GHG Protocol's principles of transparency and exclusivity.

  • Given these limitations, AIS must carefully assess the feasible decarbonization pathway before adopting a Net Zero emission target in line with the Science Based Targets initiative (SBTi). This includes monitoring the development and enforcement of clearer regulatory frameworks that will shape future compliance and implementation.
