Thanks, Christian. Hi, everyone. Welcome to Aurora Mobile's 2026 First Quarter Earnings Call. Before I comment on our Q1 results, I would like to remind everyone that we have uploaded the quarterly earnings deck on our IR website. You may refer to the deck as we proceed with the call today. As we've done in the past, the simple description that I would give to the first quarter of 2026 is a good spring brings a good year. Within this first quarter of 2026, our achievements are as follows: Firstly, in this quarter, the group recorded revenue of RMB 93.3 million, representing a solid 5% year-over-year growth. Secondly, our global flagship product, EngageLab continues to shine. The EngageLab ARR for March 2026 surged to a record high of $11.7 million, representing 172% year-over-year growth. Thirdly, gross profit grew by 13% year-over-year. Gross margin improved by 490 basis points between the year. Along the way, we delivered the fourth consecutive quarter of U.S. GAAP net profit. Trust you would agree with me, the Q1 that we have delivered was indeed a fairly good set of financials, and this is a great way to kick off a brand-new 2026 financial year. Let me now share more on the business aspects. Q1 of each year is always the tough quarter for majority, if not all of businesses. Just to share, within the first quarter of the year, we have the shorter month of February, coupled with the long Chinese New Year holidays, business activities tend to be slower at this time of the year. Despite the slower quarter of the year, we worked harder and smarter and managed to pull through with relative excellent results. Our total Q1 group revenue reached RMB 93.3 million, representing a solid 5% year-over-year growth. In this quarter, Developer Services recorded great 15% revenue growth year-over-year, but vertical applications revenue dipped 19% year-over-year. Developer services revenues, which consists of subscription service and value-added services delivered strong performance with 15% growth year-over-year but decreased 6% quarter-over-quarter. Our core business, developer subscription services delivered another quarter of excellent revenue number of RMB 64.9 million, representing growth of 21% year-over-year and 5% quarter-over-quarter. The year-over-year revenue growth was mainly driven by increases in both customer number and ARPU. In this quarter, subscription revenue recorded its highest level in history yet at RMB 64.9 million, surpassing the RMB 61.9 million high level in Q4 of 2025. Now let's move on to the update on our global flagship product, Engage Labs. As we have seen in the past 12 to 18 months, Engage Labs is now the indisputable primary driver of revenue growth for Aurora Mobile. and it is on great acceleration path. First, EngageELabs ARR has refreshed its own record and achieved a new milestone of $11.7 million as of March 2026. For the second consecutive quarter, we recorded very remarkable year-over-year ARR growth. In this quarter, the growth was 172%. Secondly, EngageLab continues to record another strong quarter. Cumulative signed contract value amounted to RMB 185 million by the end of Q1 of 2026. In Q1 alone, we won and signed up about RMB 28 million worth of new contracts. It has again shown the great growth momentum for this business. Thirdly, we continue to witness the influx of new global customers signing up to purchase EngageLab. In this quarter alone, we have converted and won over 223 new customers all over the world. The customer number has grown by 120% year-over-year to 1,864. We are very pleased with the new wins. Fourthly, the recognized revenue for EngageLab in Q1 of 2026 reached RMB 24 million, representing an outstanding 210% growth year-over-year. We continue to see great strength in EngageLab business expansion. The revenue growth, new wins and great ARR numbers were all result of the great work done by the team to meet and exceed overseas customers' needs and expectations quarter-over-quarter. We saw more customers converted to using EngageLab platform due to the superior suite of products we have to address their needs. Equally important is our service-oriented mindset to attend to and resolve customers' issues on a timely basis. Let me take a few minutes to share with you on our Aurora Mobile competitive advantages based on what I have witnessed for the past 18 to 24 months and why we can grow the EngageLab revenue with strength quarter-over-quarter. Firstly, over the years, we have built mature, highly concurrent and elastically scalable underlying infrastructure polished through years of commercial operation. This infrastructure supports massive data processing, real-time delivery and global traffic scheduling for our customers. Secondly, we have completed global market layout at an early stage and have established solid brand recognition in overseas digital service sectors. Thirdly, we possess exclusive capabilities, helping our customers to unify their full life cycle user data, covering acquisition, activation, engagement, retention and conversion. Fourthly, our products are equipped with self-developed native AI technology, deeply embedded in full product scenarios together with standardized automated workflow engines. Our solutions help customers boost operational efficiency, realize intelligent management and cut labor costs significantly. Fifthly, we have spent considerable effort ensuring we fully comply with global stringent data regulations, including privacy protection, cross-border data transmission and regional data residency rules, meeting market access requirements across Europe, America, Southeast Asia and other key regions. Fifth equally important is our lightweight architecture features easy access and low development barriers to developers and enterprise technical teams for cloud integration and launch. At the same time, it lowers potential customers reaching depletion barriers and greatly improve market replication efficiency. I believe these competitive advantages will no doubt solidify our position in the global user engagement space and market. These advantages are pivotal to long-term revenue acceleration in the years to come. On to our global expansion road map, we made great progress in Q1 of 2026. Within the first 3 months of 2026, we managed to sign up and finalize 9 other new overseas partners. These overseas partners will help us to sell into the local customers in their respective countries. As of now, we have 26 independent partners globally working together to help us further expand our reach and footprint to more overseas customers. Within subscription revenue, some of the notable wins in this quarter include, but are not limited to, the largest TV company in the world for their China operations, SF Express, Guo Securities, Du Security and JG International. Value-added services revenues were RMB 6.7 million, down 53% quarter-over-quarter. The decrease was mainly attributable to the absence of the traditional quarterly online shopping festivals, mainly the Double 11 or Double 12 in Q1. Now let me pass the call over to Sean Net, who will take you through the metrics on vertical applications and financial performance for this quarter.
