Thanks, operator. Good morning, everyone, and thank you for joining us for our first quarter 2022 earnings call. You may have seen early today we announced that DISH selected RADCOM to monitor their new 5G cloud network. This exciting news continues the positive momentum since the start of 2022. This is the second new 5G customer win that brings us to a total of $50 million in new contracts this year. Our first quarter was another quarter of solid revenue growth, while at the same time we significantly improve our bottom line. Revenue grew 16% year-over-year for the first quarter, reaching $10.6 million. This is our 11th straight quarter of revenue growth year-over-year, and I'm very pleased with our results. As mentioned, DISH selected RADCOM to monitor America's first 5G Smart Network.
DISH Wireless announced a few years ago that they plan to deploy 5G network capable of serving 70% of the U.S. population by June 2023. This starts the nationwide rollout at the beginning of the month by launching first in Las Vegas. DISH announced in their recent earnings calls that they expect to launch in about 25 markets by June. We feel proud to be DISH assurance partner as they begin to roll out America's first 5G Smart Network. DISH selected RADCOM because they wanted best-in-class assurance solution that seamlessly integrates into the cloud. RADCOM ACE will monitor their standalone 5G network, the first fully deployed on public cloud. Our cloud technology will run on Amazon Web Services, AWS, and help DISH launch 5G smoothly and monitor the service quality across its nationwide rollouts.
Last month, we announced a multi-year 5G assurance contract win with a mobile network in Europe. This new order covers assurance for this European operator's 5G network. RADCOM ACE will enable the operator to monitor its end-to-end 5G network performance and provide end-to-end visibility that helps the operator make real-time data-driven decisions and proactively improve the network performance, ensuring top quality services are delivered to its customers. These wins were achieved based on our innovative cloud technology and the advanced capabilities of RADCOM ACE, which provides an intelligent-automated assurance platform built for the cloud and 5G. We believe they strengthen our position as a 5G assurance provider and are an important acknowledgement of our leadership in this market. Therefore, we expect RADCOM ACE to gain further interest for more operators and play an essential role in facilitating the transition to 5G.
With these two new customers and previous wins, our 5G strategy is paying off. At the same time, we remain focused on capturing the growth potential we see in our current sales pipeline with both new and existing customers. We also see good momentum for the 5G market in the mid and long term, and believe it will be a catalyst for growth as the market ramps up, creating more sales engagements that can bring additional multi-year contracts and increased market share. We believe that our 5G strategy provides us with a foundation for future revenue growth beyond our account sales engagement. With the market evolving rapidly, our continued investment in research and development to extend our technological leadership within this space is vital. We believe this to be a key enabler for our future business.
We will continue to invest strategically in R&D to enhance our RADCOM ACE solution, increase our 5G capabilities, expand our AI-driven insights, and seamlessly integrated our solution to the cloud. All these capabilities are aligned with the market needs and have already borne fruit, as noted with our recent wins. Our pipeline continue to be healthy and expand while having a good mix of opportunities from our current installed base and new customers. We also see positive momentum with the number of engagements, the level of engagements, and our pipeline's total addressable market size. We believe that our position as best-in-class assurance provider for cloud-native 5G networks and our cloud expertise and knowledge will continue to drive positive returns. The bottom line is that the demand looks strong, and we have a solid pipeline of opportunities that has the potential to increase our market share. Turning to the installed base.
Last month, we announced that AT&T renewed its multi-year assurance contract with RADCOM as we entered our sixth year of partnership with this leading telecom operator. With this contract, we have a significant backlog that provides good visibility into 2022, and we expect our business with AT&T to remain strong as we continue our partnership. AT&T mentioned in a recent earnings call that their Net Promoter Score are up year-over-year. In addition, they are experiencing historically low churn levels, which they assign to the improvements to the customer experience. We believe that assurance solution are vital for monitoring service quality and ensuring a good customer experience. Therefore, we continue delivering cutting-edge software releases as we support the evolution of their network and monitoring their customer experience as they continue evolving their underlying network infrastructure to the cloud.
Rakuten Mobile achieved a very high score in newly published report from Ookla, which compared network performance in Tokyo with other cosmopolitan cities all over the world. This report demonstrates how Rakuten Mobile has deployed a high-performing quality network in Japan at lightning speed using the latest cutting-edge technology that competes with leading operators worldwide. Rakuten has stated our solution importance in supporting their journey as they build the world's first virtualized network. Our solution provides end-to-end service and subscriber visibility in a cloud-native environment, and it's vital to help them ensure network performance and automate their network operations. We are delighted with the progress in our partnership with Rakuten. We continue to develop our solution using the latest cloud-based deployment processes to provide state-of-the-art software releases as the network continually evolves.
We believe this work will continue helping our product mature and provide valuable experience when more operators implement standalone 5G and look to our 5G standalone assurance expertise. In February, our sales team attended the Mobile World Congress in Barcelona, Spain, the leading telecom industry event. The event was held in person after a couple of years due to COVID limitations. As we covered in a recent blog post that summarized the congress, we saw evidence of our belief that real-time analysis through automated assurance will be vital for 5G network operations. Operators need to make their network more intelligent, dynamic, and autonomous to deliver quality 5G services. Strong themes at the congress were the transition to 5G standalone, cloud-based networks, public cloud providers, and Rakuten Symphony.
All these are areas of interest for RADCOM, and inquiries about our solution were very positive, which we believe will lead to additional sales opportunities. Similar to the Mobile World Congress returning, we see that in-person industry events in general are starting to return. After two years of being an online event in the US, the BIG 5G Event , the leading industry conference in North America, is back to an in-person event. We see this is happening globally, which is a positive sign as we believe that in-person meetings are starting to resume. As a result, we will be able to generate more sales opportunity and advance our current engagements. We believe the 5G market remains strong, while still only being at the early stages. We see that the direction and momentum of our market are very positive and align with our strategy.
The complexity of these new 5G network architectures requires automated assurance solution to isolate network issues, optimize performance, and provide cornerstone to building network with extensive automation. We also hear this from our customers. To summarize, I am incredibly pleased with our performance at the start of fiscal year 2022. Revenues are up year-over-year, and we improved our bottom line. In addition, we continue to receive industry-wide recognition by telecom operators rolling out advanced cloud-based 5G networks and looking for forward-looking assurance solution to help their 5G transformations. We are excited to win several new noteworthy multi-year assurance contracts. We were selected by DISH as the assurance vendor to monitor America's first 5G Smart Network and added another new customer in Europe for a further 5G assurance contract. We look forward to providing our advanced cloud-native software to help ensure great mobile experiences for more subscribers.
Our cloud and 5G assurance expertise continue to expand through multiple customers deployments, which we believe will become a key differentiator as the market gains momentum. We are helping operators make data-driven decisions in real time by transitioning to software-based, more intelligent, and more automated networks. I am confident of our future success and the business strategy we are pursuing with our innovative cloud-native offering and the role we expect to play in the 5G transformation. Based on our recent wins that provides greater visibility and our healthy pipeline of opportunities, we are optimistic about our ability to deliver a growth year above our initial revenue guidance provided in February. Therefore, we are increasing our fiscal 2022 revenue guidance from a range of $42million-$45 million to a range of $43million-$47 million.
With that, I would like to turn the call over to Hadar Rahav, our CFO, who will discuss the financial results in detail.
Thank you, Eyal, and good morning, everyone. Now please turn to slide eight for our financial highlights. To help you understand the results, I will refer mainly to non-GAAP numbers which exclude share-based compensation. We ended the first quarter of 2022 with $10.6 million in revenue, increasing from $9.1 million in the first quarter of 2021. We are pleased with our consistent growth trend, representing 11 consecutive quarters of year-over-year growth. Our gross margin in the first quarter of 2022 on a non-GAAP basis was 74%. Please note that our gross margin can fluctuate depending on the revenue mix. Our gross R&D expenses for the first quarter of 2022 on a non-GAAP basis were $4.9 million, a slight increase of $113,000 compared to the first quarter of 2021.
We received a grant of $218 thousand from the Israel Innovation Authority during the quarter, compared to a grant of $68 thousand in the first quarter of last year. As a result, our net R&D expenses for the first quarter of 2022 on a non-GAAP basis were $4.7 million compared to $4.8 million in the first quarter of 2021. We expect the Israel Innovation Authority grant in the second quarter to be a similar level as in the first quarter. Sales and marketing expenses for the first quarter of 2022 were $2.6 million on a non-GAAP basis, increasing $227 thousand compared to the first quarter of 2021.
G&A expenses for the first quarter of 2022 on a non-GAAP basis were $825,000, with no significant change from the first quarter of 2021. Operating loss on a non-GAAP basis for the first quarter of 2022 was $274,000 compared to an operating loss of $1,130,000 for the first quarter of 2021. Net income for the first quarter of 2022 on a non-GAAP basis was $614,000 or a net income of $0.04 per diluted share compared to a net loss of $1,030,000 or a net loss of $0.07 per diluted share for the first quarter of 2021. The positive net income was due to financial income derived from interest and fluctuation of foreign exchange.
On a GAAP basis, as you can see on slide 7, our net loss for the first quarter of 2022 was $0.6 million or a net loss of $0.04 per diluted share compared to a net loss of $1.7 million or a net loss of $0.12 per diluted share for the first quarter of 2021. At the end of the first quarter of 2022, our headcount was 286. Turning to the balance sheet. As you can see on slide 11, our cash equivalents, and short-term bank deposits as of March 31, 2022, were $70.9 million. That ends our prepared remarks. I will now turn the call back to the operator for your questions.
Thank you. Ladies and gentlemen, at this time, we'll begin the question and answer session. If you have a question, please press star one. If you wish to cancel your request, please press star two. If you are using speaker equipment, kindly lift the handset before pressing the numbers. Your questions will be pulled in the order they are received. Please stand by while we pull for your questions. The first question is from Arjun Bhatia of William Blair. Please go ahead.
Perfect. Thank you very much for taking my questions and congrats on the DISH win. Maybe I'll just start there. With the subscription model, can you just give us a sense of the timing of how that deal may layer into the model over time? Is that something that can be fully ramped this year sometime, maybe Q3, Q4? And then how do you think about the future expansion opportunity you have with DISH as they roll out, is there room for further expansion there?
Hi, good morning. Dish, we are very excited from our new announcement about the win of the agreement with DISH Wireless. This is, as our business model with other accounts is a multiyear subscription like concept that we are expecting revenue to be over the multiple year course. The win is recent, and it typically takes one or two quarters until revenue starts. We expect revenue to start in the second part of the year, while most of the revenue will come in the following years, and we will get into full capacity as we evolve. Dish, as you probably aware, we are building our new 5G network, and we cover in the agreement this multiyear term.
We are definitely looking and excited to further expand with them into additional areas and expand with them as they grow. As they just announced this week in Las Vegas, they are looking to go nationwide and capture dozens of millions of subscribers. It's definitely a very exciting time for us.
Perfect. That's very helpful. If I could just ask on the product side, you know, can you touch a little bit, not just with DISH, but overall in terms of the pipeline you're seeing. What role is AI and kind of, you know, predictive analytics playing in driving pipeline and new business? Obviously, that's a big value proposition for these network operators, where they wanna predict an outage before it occurs, and they wanna get better visibility into their networks. Is that a major part of the conversations that you're having with customers? How has that dynamic and the conversation changed over the last year or so?
Yeah. Actually, this is a great question, as in the last two years, we were very busy building the infrastructure and the, I would call it, the basic capabilities in order to have the best solution to monitor 5G networks. Last year, we announced our RADCOM AIM capabilities, which are exactly addressed, as you mentioned, how we can do more predictive and more automated analytics and generate insight from the network. This is actually becoming our secret sauce, and in many occasions, we see more and more interest from customers to see not only how they can monitor and ensure their network, but really how they can use these advanced technologies to become more efficient, to enhance their automation, and to get more of the data that is collected by the assurance solution. Definitely this is something that is being discussed.
It's something that captures a lot of interest, and I see more and more demand for this technology as we go. This is part of the area we are going to continue investing as part of our R&D investments.
Great. Last one for me. You mentioned, you know, Mobile World Congress in Barcelona. Just with the traction that you're seeing in the pipeline with reopening, and travel and expenses returning, how do you think about the change or the increase in operating expenses as we get back to in-person events and your salespeople, you know, start going out and having in-person meetings again? Should we expect the second half of the year to ramp up as travel comes back? You know, I assume that's obviously baked into guidance, but we just would love to hear how you're thinking about that, as the year progresses here.
Yeah. First of all, we are very excited to see that the industry is starting to get back to on-site. Some of the effect is already there as we resumed in the last quarter and even in the previous quarter, some of our travel and on-site engagements. We do expect to see slight increase on our sales and marketing due to these on-site events, but we are all eager to meet our customers, so I believe this would enhance our ability to close new business. Mainly as RADCOM, that we are targeting to land and expand into new accounts. This is definitely gonna help us to get more confidence for more customers. Overall, we are very happy from this new trend, and hopefully with COVID, you never know, hopefully this will continue during 2022.
Slight increase, not something dramatic. Yeah, some of the expenses are going to be higher as travel has a cost.
Perfect. Yeah, I think we're all for that return to in-person events and seeing everybody in person. Thanks for taking the questions. Congrats again.
Thank you.
There are no further questions at this time. This concludes the RADCOM Ltd. first quarter 2022 results conference call. Thank you for your participation. You may go ahead and disconnect.
