Let's now turn to Slide number 4, which involves non-GAAP metrics.

Thank you, Tony, and good morning, everyone. Welcome, and thank you all for joining us today. Let's turn to Slide number 6 for a brief recap of our non-GAAP financial results for the first quarter of fiscal 2024. We delivered solid financial performance in the first quarter of fiscal year and released several key product offerings since our last earnings call. Revenue was $211.1 million, representing year-over-year growth of over 1%. We expanded both our gross margin and operating margins and grew our diluted EPS by nearly 30% year-over-year to deliver $0.31 per diluted share in the period. We also accomplished several product milestones with the release of our next-generation solutions that have already been well received by customers, and that we expect to start contributing to revenue in the second half of the fiscal year. This includes the release of our visibility with our broader platform that provides performance, security, and availability across one common data framework. By proactively identifying areas of complexity, fragility, and risk, the platform unlocks insights at unparalleled scale to deliver the intelligence needed to increase visibility, improve agility, and keep data and applications secure. Additionally, we relaunched our Omnis Cyber Intelligence Solution. This next generation of OCI is an advanced network detection and response for solution that uses highly scalable deep packet inspection and multiple threat detection at the source to detect threats in real-time. OCI also applies historical investigation of high-fidelity network metadata and packets. In the face of rising cyber threats, OCI provides security teams with real-time packet level visibility across their digital infrastructure and helps identify threats earlier in the attack life cycle. OCI also quickens investigation by gathering network-based forensic evidence to reduce the Mean Time to Response. OCI is a valuable tool for verifying the effectiveness and improving the existing cybersecurity ecosystem, ensuring compliance, and lowering the risk of successful cyber-attacks. We also released our two new DDoS solutions. The first is adaptive DDoS, which helps protect enterprises from rapidly spreading and dynamic DDoS attacks. It adapts to the evolving threat landscape and automated countermeasures used to address cyber-attacks, including the latest multi-vector dynamics attacks. And the second is mobile security, which extends our powerful DDoS capability that service providers currently leverage in their wireline networks to now protect their mobile network and address their distributed threat surface. Now let's move to Slide number 7 for some further perspective on market and business. Starting with our enterprise customer vertical. In the first quarter of fiscal year 2024, enterprise revenue grew nearly 13% year-over-year, driven by the expansion in both our cybersecurity and service assurance businesses. We remain confident that our value proposition of extending visibility to the edges of the network will continue to resonate with enterprise customers seeking to cover blind spots, address control challenges, and facilitate their leverage of off-premise and cloud solutions as part of their digital transformation and new network architecture initiatives. Moving to our service provider customer vertical. As expected, revenue in the first quarter for this vertical declined approximately 9% year-over-year, primarily due to the lower level of radio frequency propagation modeling project revenue in the second quarter compared with the same quarter last year. We continue to see domestic and international carriers investing in their 5G deployments. Notably, several carriers now have the spectrum and deployed stand-alone networks in certain markets and are ready to drive traffic over those networks once 5G required applications materialize. We believe that as the 5G adoption advances and 5G traffic volumes increase, our core visibility and cybersecurity solutions will be required. We are prepared and ready to support carriers through this inevitable transition with our differentiated solutions. Michael will provide more insight regarding customer orders in the vertical during his remarks. Now let's move to Slide number 8 to review our outlook. Looking ahead, we remain excited about the market opportunity we are seeing for both our existing and new solutions, and are reiterating our fiscal year 2024 outlook. We also continue to see the supply chain challenges that drove the increase in fulfillable backlog resolving and anticipate that fulfillable backlog will continue to return to more normalized levels. We remain focused on operating the business with a balanced approach to driving revenue growth and profitability as we manage through the dynamic macro environment and position NetScout to deliver long-term sustainable value for our stakeholders as guardians of the connected world. In summary, we delivered solid first quarter financial results and achieved several product milestones that establish a foundation for delivering our objectives for fiscal year 2024 and beyond. We remain confident that NetScout is well positioned to help customers address the challenges and opportunities of today's digital world through our unique and expanding solutions. We look forward to sharing our progress with everyone throughout the remainder of our fiscal year. With that, I'll turn the call over to Michael.

Thank you, Anil, and good morning, everyone. Slide 10 outlines the areas that I will be covering today, starting with Customer Win highlights in the first quarter. In our enterprise customer vertical, our proven technology and long, productive partnerships with our install base of customers have always been a strong foundation for our business. As customers continue to adapt, advance, and expand their IT strategies, they continue to depend on NetScout to ensure the success of these transitions. As an example, during the quarter, we won a mid-seven-figure service assurance order with a large US regional bank in support of their data center transformation. The opportunity arose from the bank's initiative to upgrade its infrastructure from on-premises to a distributed, co-lo based architecture. NetScout's solutions have been critical to several areas of the bank's business, including online banking and Unified Communications call centers. Our long and productive partnership positioned NetScout to win the business, despite the competitive bidding process. Now, turning to the service provider customer vertical, we remain focused on supporting both our domestic and international carriers' 5G network evolutions. We also continue to support our service providers in their security efforts as cyberattack incidents permeate and threat surfaces continue to expand. As examples from the quarter, on the service assurance front, a long-standing Tier-1 North American carrier customer placed additional orders with us amounting to a mid-seven-figure sum as they continue to advance their 5G projects. On the security front, a mid-sized international service provider customer placed a low-seven-figure order for our Arbor products to upgrade their DDoS protection, replacing a competitor. The main driver for this investment was to deliver a reliable so-called 'clean pipe,' leveraging an integrated detection and mitigation solution for their high-value customer base. We won the order due to our superior technology, strong reputation, and positive references from the leaders in their sector. These strengths, combined with our recent innovative new product offerings, should continue to drive customer interest in our best-in-class solutions in the rapidly evolving cybersecurity environment. Turning to go-to-market activities, we remain focused on promoting our industry leadership, trusted brand, next-generation solutions, and platform. This included attending several high-profile events such as the RSA conference, Cisco Live, Dell Technology World, and Big 5G. In the second fiscal quarter, we plan to participate in VMware Explore and Black Hat, to name a few. Looking ahead, NETSCOUT plans to host its customers and partners at our Annual Engage Technology and User Summit from October 2nd to October 5th this year in Orlando, Florida. At Engage 2023, we'll demonstrate how our Visibility Without Borders Platform provides a unified approach to addressing the industry's most pertinent issues, including how performance, security, and availability challenges are multiplying and are often interconnected and overlapping. We'll also highlight our next-generation Omnis Cyber Intelligence solution and our new DDoS products such as Adaptive DDoS and Mobile Security. Thank you, everyone. That concludes my remarks, and I will now turn the call over to Jean.

Thank you, Michael, and good morning, everyone. I will review key metrics for our first quarter of fiscal year 2024 and provide some additional commentary on our fiscal year 2024 outlook. As a reminder, this review focuses on our non-GAAP results unless otherwise stated, and all reconciliations with our GAAP results appear in the presentation appendix. During the quarter, total revenue grew 1.1% year-over-year to $211.1 million. Product revenue declined 3.7% and service revenue grew 5.4%, both on a year-over-year basis. We ended the first quarter with backlog of approximately $16 million, consisting of approximately $12 million of fulfillable orders and approximately $4 million of radio frequency propagation modeling projects. We anticipate that backlog will return to historically normalized levels as global supply chain challenges appear to be subsiding and as radio frequency propagation modeling projects have led to the deployment of the 5G infrastructure needed for supporting business and consumer applications. Our first-quarter fiscal year 2024 gross profit margin was 78.3%, up 3.8 percentage points over the same quarter last year. As you may recall, the prior year's quarterly gross margin was impacted by approximately $15 million in radio frequency propagation modeling projects, which had an average gross margin of less than 30%. Quarterly operating expenses increased 3.6% year-over-year, primarily attributable to increased sales headcount, travel, and events. We reported an operating profit margin of 14.0%, compared with 11.7% in the same quarter last year. Diluted earnings per share were 31 cents, compared with 24 cents in the same quarter last year, an increase of 29.2% year-over-year. Turning to slide 13, I'd now like to review key revenue trends by customer verticals and product lines. For the first quarter of fiscal year 2024, our enterprise customer vertical revenue grew 12.9%, while our service provider customer vertical revenue declined 9.3%. During the quarter, our enterprise customer vertical accounted for 52% of our total revenue, while our service provider customer vertical accounted for the remaining 48%. Now, turning to our product lines. In the first quarter of fiscal year 2024, our cybersecurity revenue increased by 9.9% and our service assurance revenue declined 2.4%, both on a year-over-year basis. Turning to slide 14, which shows our geographic revenue mix. Compared to last year's first quarter, our revenue was less concentrated in the U.S. due to the prior year's higher radio frequency propagation modeling project revenue. There were no customers representing 10% or more of our total revenue in the quarter. Slide 15 details our balance sheet highlights and free cash flow. We ended the quarter with $390.5 million in cash, cash equivalents, marketable securities, and investments, representing a decrease of $37.4 million since the end of fiscal year 2023. Free cash flow for the quarter was a use of $24.3 million. From a debt perspective, we ended the first quarter of fiscal year 2024 with $100 million outstanding on our $800 million revolving credit facility, which expires in July 2026. We currently have capacity in our share repurchase authorizations and, subject to market conditions, plan to be active in the market. To briefly recap our other balance sheet highlights, accounts receivable, net, was $108.3 million, a decrease of $35.6 million since March 31, 2023. The Days Sales Outstanding (DSO) metric at the end of the first quarter of fiscal year 2024 was 44 days, in line with the end of the first quarter of fiscal year 2023, and a decrease from 58 days at the end of our fiscal year 2023. Let's move to slide 16 for commentary on our outlook. I will focus my review on our non-GAAP targets for fiscal year 2024. As Anil noted earlier, we are reiterating our non-GAAP outlook for fiscal year 2024 that was presented during our May 4, 2023, fourth quarter and full fiscal year 2023 earnings call. As a reminder, for fiscal year 2024, we continue to anticipate revenue in the range of $915 to $945 million, which implies a low single-digit growth rate at the midpoint of the range. The effective tax rate is anticipated to be in the range of 20 to 22%. Assuming approximately 74 to 75 million weighted average diluted shares outstanding, we expect non-GAAP diluted earnings per share to be between $2.20 and $2.32, which implies a mid-single-digit growth rate at the midpoint of the range. I'd also like to offer some context on the first half of fiscal year 2024. At the midpoint of our full fiscal year 2024 outlook ranges, for revenue we continue to anticipate delivering approximately 46 to 48 percent of our revenue outlook during the first half of the fiscal year. For earnings per share, we anticipate delivering mid-single-digit diluted EPS growth for the first half of the fiscal year, on a year-over-year basis. That concludes my formal review of our financial results. Thank you, and I'll now turn the call over to the operator for Q&A.

Thank you, and I'll now turn the call over to the operator for Q&A. At this time, if you would like to ask a question your telephone is currently unmuted. We'll take our first question from Matthew Hedberg with RBC Capital Markets.

Great congrats on Q1, Anil, maybe to start with you. Between your service assurance business, it was down obviously a little bit, and enterprise was up significantly. Can you give us a sense just on overall demand trends? Do you think there's been some form of stabilization? Obviously, you guys have delivered consistent results here. But what are you hearing from customers out there from a buying perspective? And maybe where you most optimistic from a demand perspective as this year continues to progress?

Yes. Thanks, Matt. So, I think the first thing is the quarterly trend on service provider business usually has not been meaningful because of lumpy deals. On a year-over-year basis, there's not much change from what we talked about at the prospect of the last conference call. You have heard some earnings and challenges in the service provider, which sometimes tend to lengthen the sales cycle. But overall, the biggest investment we have made on the product side this year is combining the Arbor and NetScout technology to create some new solutions. We relaunched that OCI product, which we talked about as well as we announced new options and new features in the form of adapted DDoS and some other features in both the service provider side, which is the mobile security and on the enterprise side. So, we see that as we are expecting this to be a growth area and more so on the enterprise side this year, but also on the service provider side.

That's helpful. Actually, that was a segue into the next question on OCI in particular. Maybe just a little bit more color on what that means from a product perspective, a go-to-market perspective, how material is that relaunch? And from a pipeline generation perspective, is that one of the bigger announcements coming out of the cyber-attacks?

Yes. So right now, since we just relaunched the product and announced it in the April timeframe, I think it does not have an impact on the one earlier, but we are expecting some improvement in that area quickly and hopefully have an impact in the second half. The big change is that the industry is really focused on the mitigation of cyber threats, and there has been less and less focus on early detection, which we think is the key to success in dealing with cyber threats. So that’s a big change that doing analytics at source to perform more detection early in the life of the cyberattack is what we see as the differentiator in this NDR space and network detection and response.

And we'll take our next question from James Fish with Piper Sandler.

Maybe just a follow-up on Matt's initial question. What are you guys seeing specifically with your Tier 1 North America carrier customers, given some of your competitors were kind of out there talking earlier this quarter about digestion and inventory stuffing? Just trying to understand how you guys feel about the pipeline in those large customers.

Well, if you take the radio frequency orders out of the picture and both the backlog and that, I think the pipeline is good overall. But we don't just do business with Tier 1 carriers; people call Tier 2 is also a significant portion of our business where there are about 10 or so Tier 2 providers, and also some of the cable companies like Charter and Comcast are getting into the 5G business. So, we think we can make up for some of the shortfalls if there are challenges on the service on the traditional mobility provider side with these initiatives that we can pursue. All the top 4 or 5 cable operators are big customers of NetScout already on both the Arbor side and the fixed line side. So that's how we see the overall service provider business; our mobility, both on the security side and on the service assurance side, I think we are in good shape.

Got it. And Jean, for you. On the backlog side, first off, I appreciate the continued disclosure here as we start to normalize overall. But it sounds from last quarter pretty meaningfully. Is this level of backlog of $16 million or so normal as we think about coming out of fiscal Q4 into fiscal Q1? Or what's giving the confidence in the outlook then? It seems like it's about half of your normal backlog if we compare it to long-term disclosures where it was somewhere around $25 million, $30 million in the past in fiscal Q4.

Yes. Actually, if you look back over a long period of time, and I would say at least the last 10 years, our average backlog has probably been closer to somewhere between $10 million to $15 million. It’s been as low as around $200,000. Just to reiterate, the backlog started growing in Q3, Q4 of FY ‘22, and that was again due to the hardware issues in the supply chain. So, people were buying software. As we said in the comments, we see it normalizing back to somewhere probably between $10 million to $15 million. Obviously, we always like backlog. So, if we have the opportunity to continue, we would be very happy with that. What gives us confidence to reiterate our revenue guidance is a few things. One, as you've seen in the headlines, the 5G infrastructure has been pretty much laid down. I can point to all of the radio frequency propagation modeling projects that we had; the antenna is capturing signals, the RAN network is getting established. For us, it’s less about the infrastructure build and more about the applications that will go over the 5G network. What we hear when we talk to various people in the industry is that hopefully, private networks within enterprise would be the first killer app. That has been slower to start mostly due to the chip shortage. We are hopeful that since the 5G infrastructure has been established, the applications will start to bring production traffic, which is where our products are really needed. As Anil said, in security, we have the relaunch of OCI, which we discussed. In talking to certain salespeople, they’ve seen pockets of sales, especially internationally, where they have a lot of opportunities where customers are really liking what we can do. We also have mobile security, which has launched and has been in development for a few years. Anil also mentioned the adapted DDoS. When we point to those areas, this is what we would give confidence to the range of $915 to $945 million at this point.

I will take our last question from Kevin Liu with K. Liu & Company.

From a near-term perspective, given the government business that typically hits in the September quarter. Just wondering how that pipeline looks to you today and whether you expect any sort of meaningful uptick in that revenue this year versus last year?

We actually had a good overall Q1 for government, including some federal. So right now, again, they are our big demand for our products, and it always is what gets funded. We probably would see right now being consistent on a year-over-year basis with what we had in Q2 of last year.

Got it. And then just with all of the new security announcements that you guys have, do you expect that to contribute meaningfully to the second quarter results? Or would we still see kind of a more normal mix between your service provider and enterprise business? And then maybe longer-term, just when do you think security starts to shift more materially in terms of the overall revenue mix here?

If we examine the security revenue, it primarily consisted of DDoS, which accounted for nearly all of last year's security revenue, with a small contribution from OCI. Our strategy to expand the security business encompasses three key areas: enhancing mobile security and other initiatives on the service provider front, refreshing our DDoS solutions for enterprise clients, and growing OCI within the enterprise security domain, which had minimal impact last year. We anticipate that the growth in the security sector this year will significantly exceed the overall growth of the business.

And it appears that we have no further questions at this time. I will now turn the program back over to Tony Piazza for any additional or closing remarks.

Thank you, operator. This concludes our call for today. Thank you all for joining us and enjoy the rest of the day.

That concludes today's teleconference. Thank you for your participation. You may now disconnect.
