Thank you, Angela, and hello, everyone. Welcome to our fourth quarter 2025 results conference call. To begin, I am pleased to report our exceptional financial performance for 2025, driven by our dedicated efforts. Chunghwa Telecom's revenue, operating income, income before tax and EPS for 2025 all exceeded the upper end of our guidance, reflecting our strong execution and market-leading position. On the revenue front, our full year revenue reached an all-time high, demonstrating our continued focus on strengthening our core businesses and active expansion in the ICT sector. Notably, our full year EPS of TWD 4.99 marked an 8-year high, extending our annual growth momentum for the sixth consecutive year. This milestone underscore our commitment to driving innovation and enhancing long-term shareholders' value. Based on the strong outperformance in 2025, we are entering 2026 with confidence for our telecom businesses. We see Taiwan's mobile market remaining stable and favorable to us as the market leader. We are also pleased with our fixed broadband performance and will extend the successful existing strategy for further ARPU enhancement. In terms of ICT business, our technology capability will continue to remain cutting edge to support future growth. A particular highlight is our satellite opportunities as we believe demand of satellite services as the communication backup solution will increase with our satellites of OneWeb and SES commencing operation in 2025. The Astranis satellite will join in second half of 2026 to enhance our multilayer satellite capability. Furthermore, we will also focus on extending pre-6G-related opportunities in AIoT, satellite and big data services and expect their combined revenue to surpass the TWD 10 billion in 2026. We particularly expect to convert our AI capabilities into our service offering. We expect to assist our customers to integrate AI into their operational processes, legal compliance and infrastructure management. In addition, as a leader in AI drive connectivity, we are introducing AI edge computing into our AIDC to create a new revenue stream alongside our continued construction of AIDC in 2026. Ultimately, in the fourth quarter, we were honored with multiple awards recognizing both our ESG accomplishments and the technical acknowledgment. We won The Asset's Jade Award for corporate sustainability leadership for the fifth time, received the several AI Innovation Award at the World Communication Awards for our smart customer services solution and was recognized as the only Taiwanese telecom company on Newsweek's World's Most Trustworthy Companies 2025 list. More importantly, we have secured 4.6 billion kilowatt hour of renewable energy through a 20-year Corporate Power Purchase Agreement, CPPA, to support our 2045 net zero commitment. Now let's turn to our fourth quarter 2025 results. Please flip to Page 4 for the business overview. Please turn to Page 5 to review our success in Taiwan mobile market. In the fourth quarter, we solidified our leadership position in Taiwan's mobile market for 2025 with record highs across all dimensions. According to data from our telecom regulator, our mobile revenue market share climbed to unprecedented 41%, while our subscriber market share rose to 39.7%, mainly driven by continued growth in the postpaid subscriber. We are pleased with this strong result. Our 5G performance was equally impressive. Based on regulators' data, our 5G subscriber market share increased to 39.2%, further solidify our industry-leading position. The 5G penetration rate among our smartphone users climbed to 46.4% by the end of 2025, while the average monthly fee uplift from 5G migration remained robust at 41%. Given this solid momentum, we were especially encouraged by our strong mobile service revenue growth in the fourth quarter, which achieved a recent record high of 4.7% year-over-year. Postpaid ARPU also grew 3.6% year-over-year. We expect this positive trajectory to continue, supported by Taiwan's favorable mobile market landscape. Let's move on to Slide 6 for our fixed broadband business update. In the fourth quarter, our fixed broadband ARPU continued its upward trajectory, reaching a new high of TWD 819 per month. This represents a 3.8% increase in revenue and a 0.5% increase in subscribers year-over-year. This strong result were driven by our high-speed upgrade promotion and MOD bundle packages, which successfully boosted customer adoption of higher tier plans. Subscribers choosing speed of 300 megabits per second and above grew by 13% year-over-year, while those opting for 500 megabits per second and above recorded a double-digit growth and the subscription for 1 gigabits per second and above doubled in the fourth quarter. Slide 7 provides a detailed overview of the highlights from our consumer application services. In the fourth quarter, our multiple-play packages, which integrate mobile, fixed broadband and WiFi services increased by 17% year-over-year, marking the 16th consecutive quarter of expansion and representing the collective growth momentum of our customer business group. In 2025, despite the absence of major global sporting event broadcasting, resulting in overall subscription loss, our Hami video service demonstrated a solid resilience as its ARPU increased by more than 25% year-over-year in the fourth quarter. Looking ahead, with the launch of Disney+ bundle this January and our ongoing partnership with Netflix, coupled with the exciting pipeline of popular sporting events such as the FIFA World Cup, Asia Games and et cetera, we expect to drive further revenue growth throughout 2026. Meanwhile, our consumer cybersecurity subscription recorded 11% year-over-year growth with revenue also achieving double-digit gains, contributing to the steady growth for our consumer business group illustrated the key development in our enterprise ICT business. In the fourth quarter, our group's ICT revenue declined by 6% year-over-year due to a higher comparison base in the same period last year, though our full year ICT revenue still recorded robust year-over-year growth. Meanwhile, our recurring ICT revenue grew 15% year-over-year, continuing to show strong momentum, supported by increases across all major service lines, particularly contributions of AIoT, IDC and international public cloud services. Looking at the specific service categories, revenue from IDC, Big Data and 5G private network grew by 19%, 3% and 88% year-over-year, respectively. IDC performance benefited primarily from project completion in Mexico, while big data service revenue increased driven by its recurring revenue growth. Revenue from 5G private network surged, supported by the project revenue recognition from both public and private sector customers. However, revenue from cloud and AIDC business declined by 16% and 27% year-over-year, respectively, due to a high base last year. Our cybersecurity service revenue also decreased by 16% year-over-year as the majority of our cybersecurity revenue for 2025 had already been recognized in 3 quarters. Notably, despite the quarterly fluctuation, both cloud service and cybersecurity business still delivered full year revenue growth. We are also proud to share that we secured an AI customer service solution to build the first integrated AI customer services system for a leading financial institution in Taiwan. Furthermore, we secured a flagship government system integration project to upgrade the labor insurance platform to next-generation infrastructure with a contract value exceeding TWD 3 billion. In addition to further leverage our sea, land and sky network deployment and expand our satellite business scale, we successfully incorporated our satellite services as part of the government's joint procurement contract framework, paving the way for more long-term service contracts from government agencies. Lastly, our deployment of remote surveillance platform for correctional institution nationwide brought us 5 additional new projects in the fourth quarter with a total contract value of TWD 150 million. We expect to further replicate and scale this success in the coming year. Slide 9 illustrates the performance of our international subsidiaries. In the fourth quarter, our international subsidiaries revenue decreased 7% year-over-year, mainly due to softened demand for voice services as well as higher comparison base in the United States and the Japan ICT market last year. However, we were glad to see a 12% year-over-year revenue increase in Southeast Asia market as we completed multiple planned construction projects in Singapore and Thailand, a trend that we expect to continue through 2026. Notably, our Malaysia subsidiary commenced operations in December 2025, aiming to provide more timely, high-efficient ICT integration services for Taiwanese and multinational enterprise in the growing Southeast Asia market. Look ahead of 2026, we maintain a relatively optimistic outlook for our global market development as we have secured several AI supply chain projects in the United States in our pipeline, including key projects in Texas and California, which is expected to significantly boost our U.S. market performance in 2026. Now let's move on to Page 10 for the financial performance of our 3 business groups. In the fourth quarter, our CBG delivered a robust 6% year-over-year revenue growth, supported in both mobile and fixed broadband services, plus higher sales driven by the iPhone demand. However, its income before tax slightly decreased, mainly dragged by the final phase of 3G telecom equipment impairment, which has fully recognized in the fourth quarter and a higher comparison base from government subsidies recorded in the same period last year. Our EBG revenue decreased by 7.9% year-over-year as most of our major ICT project has already been recognized in previous quarters, resulting in a 7% year-over-year drop in the EBG ICT revenue. Income before tax was also impacted by the onetime impairment mentioned earlier. Encouragingly, EBG mobile and fixed broadband services as well as its satellite services still delivered solid growth momentum this quarter. As for our IBG business, revenue grew by 2.5% and income before tax increased by 1.8% year-over-year, driven by rising demand for the international IDC services and stronger roaming revenue. Furthermore, we are pleased to report that our submarine cables, SJC2 and the first phase of Apricot were completed this quarter and further boosted IBG's fixed line services revenue by 2.2% year-over-year. Now I would like to hand the call over to Audrey for financial updates.
