Thank you, Constantino. Hello, everyone, and welcome to Turkcell's 2025 Third Quarter Earnings Call. On the call today, we have our CEO, Ali Taha Koc; and CFO, Kamil Kalyon. They will provide an overview of our financial and operational results for the quarter, followed by a Q&A session. Before we begin, I would like to kindly remind you to review our safe harbor statement, which is available at the end of our presentation. With that, I will now turn the call over to Mr. Ali Taha.
Ali Koç: Thank you, Ozlem. Good afternoon, everyone, and thank you all for joining us today. This quarter once again demonstrated Turkcell's strong momentum powered by disciplined operations, sharp execution and the strength of our growth engines. We delivered 11% revenue growth, reaching TRY 60 billion, driven primarily by our core telecommunication business. Strong ARPU performance, a growing subscriber base and rising data center revenues all contributed to this outstanding performance. Group EBITDA increased 11% to TRY 26 billion, achieving a solid 43.9% margin, a clear reflection of our continued cost discipline. In addition to our operational success, prudent financial management strengthened our bottom line. Lifting net income from continuing operations up by 31.8% to TRY 5.4 billion. Competition remained intense this quarter. Even so, we added 569,000 net postpaid subscribers. Through targeted pricing and upselling, mobile ARPU rose 12%, once again proving our ability to deliver double-digit growth in a highly competitive environment. Residential fiber ARPU also grew by 17.3% year-on-year in the third quarter. Our strategic growth areas also continued to perform strongly. Data center and cloud revenues grew 51%, and our renewable energy capacity from solar fields across 4 cities in Turkiye has reached 37.5 megawatt. Next page, please. We are proud to reinforce our leadership with the successful outcome of the 5G spectrum tender, a defining milestone for Turkiye's digital future. The results were exactly in line with our expectations and reaffirm our leadership position. We secured 160 megahertz of spectrum, the maximum capacity available to a single operator in this tender. This allocation enabled us to deliver speeds exceeding 1,000 megabit per second while paving the lowest cost per megahertz per subscriber among all operators. 5G will be commercially launched in April 2026, marking the beginning of a new chapter in Turkiye's digital transformation. It will empower industries such as manufacturing, transport, health care and education with high-speed connectivity to regions that currently lack fiber access. Once 5G officially launches, these customers will be among the first to experience 5G speeds. And just as we have done over the past 30 years, we will continue to lead in this new era of connectivity. We are fully ready to shape Turkiye's 5G future and drive the next wave of digital transformation. Next page, please. Let's take a closer look at the key operational highlights from the third quarter. Competition in the mobile market was strong as we expected, maintaining our dynamic and customer-centric approach, we continue to expand our customer base. We recorded 569,000 net postpaid additions, bringing our total net gains to 2 million over the past 12 months. As a result, our mobile subscriber base exceeded 39 million. Leveraging our AI-driven dynamic micro segmentation approach, we executed our upsell strategies with precision. We offered customers precisely targeted offers, moving the vast majority of our base to higher tier plan. In addition, the share of postpaid subscribers, a key driver of revenue growth, rose by 4.6 percentage points year-on-year to 79%. These efforts, together with higher seasonality, delivered double-digit mobile ARPU growth of 12%, reflecting our continued focus on value-driven growth. Our mobile churn rate was 2.6%, primarily reflecting the ongoing competition and high activity in the number portability market. Next page, please. Now let's move on to our fixed broadband operations. With a focus on fiber customers, we had a net add of 33,000 this quarter, bringing our Turkcell fiber base to over 2.5 million. Including sales over other operators' infrastructure, we introduced 55,000 new customers to high-quality fiber services. Our fiber strategy is best described by a simple principle, high quality and high speed. With this approach, since last year, we remain committed to offering 1,000 megabit per second speeds and delivering greater value to our customers. Year-on-year, the number of subscribers on these plans more than tripled. With effective pricing adjustments, a higher proportion of customers on 100 megabit per second plus plans and 88% commitment rate to 12-month contracts, our residential fiber ARPU grew 17.3% year-on-year in the third quarter. As we continue to strengthen our fiber network, we expanded our footprint with 107,000 new home passes, reaching 6.2 million households. Our 42.6% take-up rate is a clear indication that our fiber investments are effectively planned. Next page, please. Let me now turn on to our strategic areas, beginning with Digital Business Services. Digital Business Services delivered robust 97% revenue growth, reaching TRY 4.9 billion, supported by recurring service income and stronger hardware sales. The backlog from system integration projects reached a remarkable TRY 5 billion. Data center and cloud revenues continued their strong momentum, increasing 51% year-on-year in real terms. We had targeted an 8.4 megawatt capacity expansion at the beginning of 2025, guided by our vision of keeping Turkiye's data within Turkiye, and we successfully activated that capacity in this quarter. Thanks to our early-stage investment, we have established a strong market position, becoming the leading player in the enterprise colocation market. We are preparing for our next strategic move in data centers and cloud businesses, which will further strengthen our leadership. Next page, please. Now moving on to another of our strategic pillars, techfin. Our techfin ecosystem, representing 6% of consolidated revenues achieved 20% year-on-year growth in the third quarter, outpacing the group's overall performance. This growth was mainly driven by our digital payment company, Paycell, which achieved a 42% increase in revenues. Within Paycell, POS and Pay Later services were the key contributors supported by favorable regulatory revisions in mobile payment limits and broader adoption of POS solutions. Our Financell brand, providing customers with fast and flexible financing solutions continued to expand its loan portfolio, reaching TRY 7.5 billion despite the high interest rate environment. The net interest margin improved to 5%, driven by more favorable funding costs. Financell continued to support the sales of Samsung A26, locally manufactured 5G smartphone exclusive for Turkcell with a total of 54,000 contracted sales since its launch in April. Next page, please. Despite global geopolitical and macroeconomic headwinds, we delivered performance that exceed our expectations over the first 9 months of the year. In line with these strong results and the revised CPI outlook, we are upgrading our 2025 guidance. Reflecting our solid momentum and confidence in the sustainability of our results, we are revising our revenue growth expectations upwards to around 10% and raising our EBITDA margin target to 42% to 43% range. Even as we continue our intensive investment cycle, we are revising our operational CapEx to sales target to around 23%, mainly driven by the acceleration in revenue recognition. As for our data center and cloud revenues, we are also revising our growth guidance upwards to around 43%. With that, I will now hand over to our CFO, Mr. Kamil Kalyon, to walk us through the financial highlights.
