Chunghwa Telecom May Revenue NT$ 19.52 Billion, Revenue and EBITDA Both Hit Record Highs for May

　　Chunghwa Telecom announced its unaudited consolidated operating results for May 2026. In May, the unaudited consolidated revenue was NT$ 19.52 billion. Operating income was NT$ 4.35 billion, and income before tax was NT$ 4.39 billion. Net income attributable to stockholders of the parent company was NT$3.36 billion and EBITDA reached NT$ 7.77 billion, while EPS was NT$0.44.

　　According to Chunghwa Telecom, consolidated revenue increased by 5.4% year-over-year, primarily driven by growth engines of core telecom and ICT services, alongside strong iPhone sales and increased subsidiary revenue fueled by AI demand. Both consolidated revenue and EBITDA in May reached record highs for the same period.

　　ICT revenues delivered double-digit growth in May, primarily supported by the completion of AI server-related construction projects, and robust demand for enterprise-tailored private cloud solutions. As a result, IDC and cloud service revenues grew approximately 30% year‑over‑year. In addition, the successful delivery of multiple integrated projects, including tax-related systems, healthcare information systems and digital transformation initiatives, further pushed overall ICT revenue to increase by double digit year over year.

　　Telecom core services continued to demonstrate stable growth. Mobile service revenue increased by 3.3% year-over-year, driven by the continued increases in 5G subscribers, which drove steady growth in monthly subscription revenue, as well as continued growth in mobile data revenue from rising roaming demand. Moreover, the Company’s incentives provided for VIP related with the “2026 hito Pop Music Awards” effectively boosted VIP e-membership conversion with double-digit growth, enhancing customer stickiness and overall user experience. During the Mother’s Day promotional period, integrated marketing initiatives, including rate plan promotions, handset subsidies, and reward point incentives, successfully stimulated new subscriptions and handset upgrades, contributing to the overall sustained net-adds growth.

　　Fixed broadband revenue increased by 3.4% year-over-year, supported by stable demand for high-speed services, with subscribers using 300Mbps-or-higher packages growing by 14% year-over-year, reflecting an ongoing upgrade trend. Meanwhile, the number of customers subscribing Hami Video through fixed broadband showed a notable increase, supporting video revenue growth and demonstrating the Company’s success of cross-product integration.

　　In addition, revenue from international private leased circuit (IPLC) grew by 14% year-over-year, driven by the completion of domestic circuit deployment projects. This performance highlights robust demand for high-quality network infrastructure and our strong competitive positioning in infrastructure and digital transformation services.

　　As of May 2026, the accumulated unaudited consolidated revenue was NT$100.01 billion. Operating income was NT$ 22.28 billion and income before tax was NT$ 22.46 billion. Net income attributable to stockholders of the parent was NT$ 17.20 billion and EPS was NT$ 2.22.

NON-GAAP FINANCIAL MEASURES

　　To supplement the Company’s consolidated financial statements presented in accordance with International Financial Reporting Standards pursuant to the requirements of the Financial Supervisory Commission, or T-IFRSs, Chunghwa Telecom also provides EBITDA, which is a "non-GAAP financial measure”.  EBITDA is defined as consolidated net income (loss) excluding (i) depreciation and amortization, (ii) total net comprehensive financing cost (which is comprised of net interest expense, exchange gain or loss, monetary position gain or loss and other financing costs and derivative transactions), (iii) other income, net, (iv) income tax, (v) (income) loss from discontinued operations.

　　In managing the Company’s business, Chunghwa Telecom relies on EBITDA as a means of assessing its operating performance because it excludes the effect of (i) depreciation and amortization, which represents a non-cash charge to earnings, (ii) certain financing costs, which are significantly affected by external factors, including interest rates, foreign currency exchange rates and inflation rates, which have little or no bearing on our operating performance, (iii) income tax (iv) other expenses or income not related to the operation of the business.

CAUTIONS ON USE OF NON-GAAP FINANCIAL MEASURES

　　In addition to the consolidated financial results prepared under T-IFRSs, Chunghwa Telecom also provide non-GAAP financial measures, including “EBITDA”. The Company believes that the non-GAAP financial measures provide investors with another method for assessing its operating results in a manner that is focused on the performance of its ongoing operations.

　　Chunghwa Telecom’s management believes investors will benefit from greater transparency in referring to these non-GAAP financial measures when assessing the Company’s operating results, as well as when forecasting and analyzing future periods. However, the Company recognizes that:

• lthese non-GAAP financial measures are limited in their usefulness and should be considered only as a supplement to the Company’s T-IFRSs financial measures;
• lthese non-GAAP financial measures should not be considered in isolation from, or as a substitute for, the Company’s T-IFRSs financial measures;
• lthese non-GAAP financial measures should not be considered to be superior to the Company’s T-IFRSs financial measures; and
• lthese non-GAAP financial measures were not prepared in accordance with T-IFRSs and investors should not assume that the non-GAAP financial measures presented in this earnings release were prepared under a comprehensive set of rules or principle.

　　Further, these non-GAAP financial measures may be unique to Chunghwa Telecom, as they may be different from non-GAAP financial measures used by other companies. As such, this presentation of non-GAAP financial measures may not enhance the comparability of the Company’s results to the results of other companies. Readers are cautioned not to view non-GAAP results as a substitute for results under T-IFRSs, or as being comparable to results reported or forecasted by other companies.
