With that said, I would now like to turn the call over to our Chairman and Chief Executive Officer, Mr. Tao Yang. Please go ahead, sir. Thank you, Kerry, and thank you, everyone, for joining our 2021 first quarter earnings conference call. 2021 is off to a remarkable start. Yalla Group's total revenue increased almost by 40% quarter-over-quarter and reached $67.6 million, exceeding the upper end of our guidance range by 7.4%. This better performance was driven by our continued efforts to grow our user community, the effective conversion of active users into paying users, and the further advancement of our monetization capabilities and initiatives. In the first quarter of 2021, we also maintained robust profitability as demonstrated by our non-GAAP net margin of 49.7%. With the strong execution of our efforts to raise brand awareness across the Middle East and North Africa region and our effective marketing campaigns tailored to the local culture, monthly active users for our group increased by 14.6% quarter-over-quarter and reached 18.8 million. In addition, increasing user engagement on our platform drove Yalla Group's paying users up by 11.5% quarter-over-quarter to 5.8 million, leading to outstanding paying ratio of 31%. Our ability to monetize also continued to improve as our group's ARPU grew rapidly by 25.5% quarter-over-quarter, reaching $11.6 in Q1. During previous earnings calls, we announced four new products in our pipeline. Three of them are casual game platforms, including Baloot for users in Gulf countries, 101 Okey for Turkish users, and Yalla Parchis for South American users. The beta versions of all these three casual game products have been made available online, and we have also made great progress in refining the technological and user interface details of these new products over the past quarter. Our President, Saifi, will share more details with you in his part later. Our fourth new product is Yalla Chat, an instant messaging or IM product designed specifically for Arabic users. We are pleased to share that we launched the beta version of Yalla Chat in March. With this strategically significant product, Yalla Group aims to build and strengthen connections among our individual apps and create an integrated and synergistic ecosystem. To this end, we have adopted measures to attract the right talent to join our R&D and product team. This beta version supports basic instant messaging functions such as messaging, voice chatting, and video chatting. Since its launch, our development team has continued to refine and enhance the product based on user feedback, and we will gradually roll out new design features and functions on the platform based on the local user feedback and desires. The improvement and the iteration of IM product is always an ongoing process, and the initial beta stage can take more than several months. We are dedicated to perfecting the details of the product before the team decides to officially launch the new product and start full promotion. As we mentioned in our last earnings call, Yalla's top priority this year is to expand our user base with new product lineup for official launch. We plan to increase our sales and marketing activities to build out an initial user base for this product. For our existing two products, Yalla and Yalla Ludo, we will maintain our strategy for steady user growth and don't expect much change in expansion phase related to these two apps. Furthermore, as we continuously enrich our portfolio, we aim to amplify synergies among our various products and gradually build and develop a competitive Yalla ecosystem. Our President, Saifi Ismail, will elaborate more on this idea in a few minutes. We had an outstanding first quarter marked by strong growth across our primary operational and financial metrics. In just a few days, Yalla is going to have its fifth anniversary. Five years ago, we identified voice chat to be uniquely suitable for online social networking and entertainment in MENA, and pioneered the development of Yalla as the first voice-centric mobile social networking and entertainment platform in the region. Over the past five years, our leadership in this field went from strength to strength as we gradually enrich and enhance the product we offer to better serve local users, while affirming our mission to build the most popular destination for online social networking and entertainment activities in MENA. Looking ahead, we continue to closely watch trends in MENA's local culture, expand our friendly community, and build Yalla's ecosystem with various products and services tailored to local users' needs. Now, I will turn the call over to our President, Mr. Saifi Ismail, for a closer look at our recent developments. Thanks, Tao. Hello, everyone. Thanks for joining us today. As we continue to enrich our product portfolio, including Yalla Ludo, and the four new products in the pipeline, we are looking to boost synergies among individual apps to develop a more integrated ecosystem, which will help us improve efficiency in acquiring new users going forward. With this move, we expect to see an increase in the flow of users from application to application, especially between the chat rooms available on each of our products. We also anticipate seeing an increase in users' awareness of the multiple products and services provided by the Yalla Group, which will, as a whole, lead to a larger user base, longer time spent in Yalla's ecosystem, and deeper brand loyalty in the long run. We recently tested the effectiveness of advertising Yalla on Yalla Ludo in a few regions, and the resulting traffic gain for Yalla was solid. While we have observed good potential for cross-selling on Yalla Ludo, before we decide to launch this project officially, we plan to run more trials. Essentially, we will test the concept in a few countries first, progressively apply it to all other countries that we operate in, and potentially replicate the same process to help promote our upcoming new products or even collaborate with other apps in the future. Another exciting update we would love to share with you and our investors here is about our new product, Yalla Parchis. As UAE's first technology unicorn listed on the NYSE, besides focusing on serving our MENA users' needs in the internet era, Yalla is also exploring overseas opportunities in the South American market. Our first product customized for South America, Parchis, has received very good user feedback in its beta trial, and we are very encouraged by its user metrics that we are constantly evaluating. We will keep monitoring the trend, and we will share more updates for Parchis development with you next time. Yalla will continue to leverage the team's deep local insights to provide MENA local users with various products tailored to their needs and preferences, as it remains dedicated to building and developing the Yalla ecosystem. Our mission is to become the number one provider for online social networking and entertainment in the MENA region, and we are well on our way to achieve it. With that, I will now turn the call over to our CFO, Karen, who will discuss our key financial and operational results. Thank you, Saifi Ismail. Hello, everyone. Thank you for joining us. Our strong performance sustained into this first quarter, as we steadfastly executed our Group's strategy that prioritizes user experience and community development. Our first quarter revenues grew by 221% year-over-year to $67.6 million, while our non-GAAP net income reached $33.6 million, with a good rate of 263.7% year-over-year. Our non-GAAP net margin remained elevated at 49.7%, reflecting our unique monetization strategy, marketing positioning, and strong operating efficiency. I would like to walk through our financial details for the first quarter of 2021. Our revenues were $67.6 million in the first quarter of 2021, a 221% increase from $21.1 million in the same period last year. The increase was primarily driven by the widening of both Yalla's and Yalla Ludo's user base and the enhancement in Yalla Group's monetization capability. Our average MAUs increased by 206.9%, from 6.1 million in the fourth quarter of 2020 to 18.8 million in the first quarter of 2021. Yalla's MAUs increased by 81.6% to $7.3 million in the fourth quarter of 2021 from $4 million in the same period of last year. Yalla Ludo's MAUs increased by 445.4% to $11.5 million in the fourth quarter of 2021 from $2.1 million in the same period of last year. In addition, another primary contributor to our solid revenue growth was the significant increase in the number of paying users, which grew from $1.6 million in the fourth quarter of 2020 to $5.8 million in the fourth quarter of 2021. Now, let's look at our costs and expenses. Our cost of revenues was $24 million in the fourth quarter of 2021. Excluding share-based compensation expenses, cost of revenues in the fourth quarter of 2021 were $22.3 million, a 227.2% increase from $6.8 million for the same quarter last year. The increase was primarily due to an increase in commission fees for third-party payment platforms resulting from our expanding business scale. Excluding share-based compensation expenses, other components of cost of revenues as a percentage of our total revenues remained relatively stable at 33% in the fourth quarter of 2021, compared with 32.3% in the same period in 2020. Our selling and marketing expenses were $8.4 million in the fourth quarter of 2021, excluding share-based compensation expenses. Other components of selling and marketing expenses for the fourth quarter of 2021 were $5.1 million, an 81.7% increase from $2.8 million for the same quarter last year. The increase was primarily due to higher advertising and marketing promotional expenses as a result of our continual user acquisition efforts. Excluding share-based compensation expenses, other components of selling and marketing expenses as a percentage of total revenues decreased from 13.4% in the fourth quarter of 2020 to 7.6% in the same period in 2021, primarily due to strong growth in organic user acquisition through Word of Mouth, referrals, as well as brand impact, and enhanced marketing efficiency. Our general and administrative expenses were $11.7 million in the fourth quarter of 2021. Excluding share-based compensation expenses, other components of general and administrative expenses for the fourth quarter of 2021 were $3 million, a 124.4% increase from $1.3 million for the same quarter last year, which was primarily due to an increase in salaries and other benefits for our general and administrative staff, which was in turn driven by an expansion of our general and administrative staff. Excluding share-based compensation expenses, other components of general and administrative expenses as a percentage of our total revenues dropped from 6.4% in the fourth quarter of 2020 to 4.4% in the fourth quarter of 2021 due to economies of scale. Our technology and product development expenses were $3.3 million in the first quarter of 2021. Excluding share-based compensation expenses, other components of technology and product development expenses for the fourth quarter of 2021 were $3.2 million, a 277% increase from $0.9 million for the same quarter last year. The increase was primarily due to an enhancement in salaries and benefits for our technology and product development staff, which was in turn driven by an expansion of our technology and product development, arising from higher investment in new products and services. As a result of these reasons, other components of technology and product development expenses as a percentage of our total revenues rose from 4% to 4.7% year-over-year. Our operating income was $20.2 million in the first quarter of 2021, compared with operating income of $9.2 million in the same period last year. Excluding share-based compensation, non-GAAP operating income for the first quarter of 2021 was $34 million, a 257.8% improvement from the same quarter last year. Our income tax expense was $0.43 million in the first quarter of 2020, in comparison to $0.19 million in the fourth quarter of 2021. Moving to the bottom line, our net income was $19.8 million in the first quarter of 2021, a 114.6% increase from $9.2 million in the same period last year. Excluding share-based compensation expenses, non-GAAP net income for the fourth quarter of 2021 was $33.6 million, a 263.7% improvement year-over-year. Next, I would like to briefly go through our liquidity and capital resources. As of March 31st, 2021, we had cash and cash equivalents of $261.7 million as compared to cash and cash equivalents of $236.9 million as of December 31st, 2020. This improvement demonstrates our resolve and the capability to improve Yalla Group's operations on a consistent basis. As we enter the second quarter with the Ramadan fasting period taking place across MENA between 13th April through 12th May in 2021, we expect to have a relatively moderate revenue growth due to potentially reduced social and entertainment activities, which is an annual seasonal impact. We expect our revenues to be between $65 million and $71 million in the second quarter of 2021, taking the seasonality into consideration. Looking ahead, we will leverage our team's deep local insights, continue to develop the Yalla ecosystem, and enhance our brand building to further pave the runway for long-term growth, as we are committed to delivering a secure experience to our users and meaningful returns for shareholders. The above outlook is based on the current market conditions and reflects the company management's current and preliminary estimates of marketing and operation conditions and customer demands, which are all subject to change. This concludes our prepared remarks for today. Operator, we are now ready to take questions. Thank you. We will now begin the question and answer session. To ask a question, you may press star then one on your touchtone phone. If you're using a speakerphone, please pick up your handset before pressing any keys. To withdraw from the question queue, please press star then two. For the benefit of all participants on today's call, if you wish to ask your question to management in Chinese, please immediately repeat your question in English. The first question today comes from Feiya Zhao with Haitong International. Please go ahead. I will translate for myself. Thank you management for taking my questions. Congrats on a strong quarter. My question is mainly related to the Yalla Parchis. Could you please provide some color to the current stage of Yalla Parchis, such as MAU revenue, user profile, time spent, and user paying behavior? What is the most active country for Yalla Parchis now? When are you going to officially launch the product? Thanks. Hi, Feiya. I'll answer this question. Based on the feedback we received, which clearly showed love for Yalla Parchis from users in South American markets, we believe Parchis has the potential to become a popular product in this region. We have already started the promotion Yalla Parchis in Q1. According to the App Annie data, it is already among the top five in six countries under the board game category in Android. We will continue to monitor the engagement trend and look forward to sharing more feedback and data with you next quarter. We are starting to strengthen our campaigns in Q2. The numbers like the MAUs, the other operation data we will provide, we prefer to provide you later, next earnings call. Thank you, Mr. Yang. The next question comes from Bo Pei with Oppenheimer. Please go ahead. Hi, management. Thanks for taking my question. I do have two quick questions here. First is, I guess, our non-GAAP margin actually improved sequentially in one Q. I guess that's because we haven't started spending on sales and marketing yet. My question is, when do we plan to spend more on sales and marketing, especially for our new products, right? When we do that, what's going to be the impact on our net income margin? The second question is about our MAU growth outlook. Last time we talked about 10%-15% sequential growth for each quarter of this year. Can management comment on that? Any update on that? How should we think about the MAU outlook for the new products? For example, by the end of this year, what's going to be the user size for the new products? Thank you. Thank you, Bo Pei. Thank you for your question. For Q1, Yalla achieved very good net margin again. For Q2, since we are going to roll out promotions of our new products, we'll see some increase from that to our margins. In terms of how much we are going to spend in sales and marketing, it really depends on user feedback and marketing dynamics. We will adjust our promotion strategy accordingly and in time to maximize the efficiency of spending. For the Yalla and the Ludo MAUs outlook, as we mentioned last quarter, we think that both products MAU will grow by 10%-15% quarter-over-quarter in 2021. For the new products MAUs outlook, we think that it will depend on the user feedback and for the sales and marketing progress. Thank you for your question. Got it. Thank you. The next question comes from Kaifang Jia with CITIC. Please go ahead. Hi, management. Thank you for taking my question, and congratulations for a strong quarter. My question is about the YallaChat. In terms of the instant message product, how do you see the competition from other products like WhatsApp? What is your user growth strategy and timeline for YallaChat? Thank you. Good morning, Kaifang. I would like to answer this question. As a company with local teams based in UAE, we are dedicated to offering an product that's tailored to Arabic users' lifestyles, using habits, and preferences, which is the main difference between YallaChat and WhatsApp. We will build many localized features for this product and continue to refine it based on local user feedback. In terms of user growth strategy, when we think the product is ready, we will introduce YallaChat to users in our Yalla community, from Yalla and Yalla Ludo and other products, and encourage them to give it a try. In this way, we will be able to leverage the community we have built and the social connections we have fostered over the past years. Thank you, Kaipeng. Okay. Thank you. Very clear, too. The next question comes from Xueqing Zhang with CICC. Please go ahead. Thanks, management, for taking my question. First, I would like to congratulate for another strong quarter. I have a question regarding your product pipelines. Currently, both of Yalla's products are video-centric since are voice-centric, since video entertainment applications have gained a lot of attention these days, do you have any plans to launch video-centric products in the future? Can you please share more color about that? Thank you. Thank you, Xueqing. At this point, we don't have video-centric products in our pipeline. It doesn't mean that we will only focus on voice-centric products. We will keep monitoring MENA users' needs and trends in social networking and entertainment. We will continue to adjust our strategy accordingly. Thank you. Thank you. The next question comes from Fiona Shang with Jefferies. Please go ahead. Hi, management. Thanks for taking my question. Congratulations on the great results. I have two questions. The first question is about the strategies of user acquisitions. I would like to ask, are there any differences of user acquisition strategies for different products in different regions? For example, we launch a new product in South America, so what will be the marketing strategies there? My second question is about mid to long term outlook. Could management share some colors about outlooks for two to three years from now, like geographic expansion and business line expansion and product offerings? Thanks. Thanks, Fiona Shang, for the question. This is Jianfeng I'll be answering the question. Through running marketing campaigns on Yalla and Yalla Ludo over the past five years, our team has gained valuable experiences and gradually built strong capabilities in marketing. Our high user acquisition efficiency can be demonstrated by our excellent control in sales and marketing and the consistent increase in our MAUs. Besides the traditional user acquisition through advertising on media, both our Yalla and Yalla Ludo has also shown strong organic growth. At the same time, because of the high quality of the product and deep localization, our products have also been recommended for free by top platforms like Apple and Google. This all contributed to our successful user acquisition. For every new product, we will design marketing plans based on our understanding of the product's special characteristics. We will always follow our own pace in execution and adjust our strategy according to the feedback and the metrics that we keep monitoring, as it's always a very dynamic process. We also have different plans tailored for different regions to maximize the efficiency of things. For the upcoming promotion of our new product, we're very confident in our team's capabilities to achieve strong results. Thank you for the question again. I'll be answering the second question. Since for the next two and three years, MENA will certainly be our main focus. With the Yalla Parchis launch, we will keep an eye on the South American market and see if there are any other potential opportunities. In addition to Yalla Ludo, and four new products we introduced earlier, we will continue to monitor local users' needs and preferences and identify further opportunities to serve MENA users. At the same time, as we introduced earlier, we will gradually start to drive traffic from one product to another, with the dedication to build and develop our Yalla ecosystem, which will, as a whole, lead to a more integrated user community, longer time spent in Yalla's ecosystem, and deeper brand loyalty in the long run. Thank you, Fiona. Thanks. As there are no further questions now, I'd like to turn the call back over to management for any closing remarks. Thank you once again for joining us today. We look forward to speaking with you in the next quarter. If you have further questions, please feel free to contact Yalla's investor relations through the contact information provided on our website or The Piacente Group, ñInc. investor relations. This concludes the conference call. You may now disconnect your line. Thank you.
