Anil?.

Thank you, Tony, and good morning, everyone. Welcome, and thank you all for joining us today. Let's now turn to Slide #6 for a brief recap of our non-GAAP financial results in the second quarter and the first half of our fiscal year 2023.

Focusing first on the second quarter of fiscal year 2023, we delivered strong financial results and drove progress across our strategic growth priorities during the quarter. Importantly, this included further expanding our cybersecurity business. Second quarter revenue was $228.1 million, representing year-over-year growth of nearly 8%.

Our revenue expansion was driven by 10% product revenue growth and more than 5% service revenue growth, both on a year-over-year basis. Of note, our cybersecurity and service assurance product lines continued to grow in the quarter on a year-over-year basis.

With this revenue growth and our healthy operating leverage, we delivered $0.50 per diluted share in the second quarter of fiscal year 2023, representing diluted earnings per share growth of approximately 21% year-over-year. Now moving on to the first half of fiscal year 2023.

During the period, revenue was $436.9 million, growing by nearly 9% year-over-year. This increase was driven by product revenue growth of more than 14% and service revenue growth of nearly 4%. During the same period, cybersecurity revenue grew by 14%, while service assurance revenue grew by more than 6%. All comparisons are on a year-over-year basis.

Additionally, we delivered $0.81 of diluted earnings per share in the first half of the fiscal year 2023, representing diluted earnings per share growth of approximately 21% year-over-year. Now let's move to Slide #7 for some further perspective on marketing -- market and business insights.

Starting on the cybersecurity front, we recently released our DDoS threat intelligence report for the first half of 2022. In it, we highlighted many of the current trends and challenges within this critically important area.

Our report finding demonstrate how adept and sophisticated cyber criminals have become at leveraging new DDoS attack vectors and their other metrologies to attempt to bypass organization defense measures. The report also highlighted the significant geopolitical implications of today's DDoS attacks.

In short, many of these bad actors are openly embracing online aggression to cause disruption and geopolitical unrest through the high-profile DDoS attack campaigns.

[Indiscernible] with our state-of-the-art platform for increased visibility and defensibility, we play an important role in this ecosystem and remain confident in our ability to help customers navigate these challenges while also capitalizing on the opportunities of today's digital world.

In line with these trends, our Omnis suite of cyber intelligence product has continued to gain traction, although it still only accounts for a small portion of our revenue stream.

During the second quarter, for example, one of our large customers continued to integrate with the NetScout platform by incorporating Omnis into the current installation base. Additionally, we continue to innovate in the cybersecurity area, introducing new solutions like Arbor Insight to help address the evolving threat landscape.

When combined with Arbor Sightline, this solution can dramatically enhance and extend the company's capabilities in threat detection, service delivery and network operator visibility. Now let's turn to our customer verticals for more business insights, starting with our service provider.

Service provider revenue increased by 11% year-over-year in the first half of fiscal year 2023. This increase was primarily due driven by higher revenue related to radio frequency propagation modeling project from Tier 1 carriers in North America.

Importantly, we continue to seek carriers to invest in the 5G deployment, both for planning purposes as well as for stand-alone build-out, where these -- where these same carriers also are starting to deploy commercial traffic. In our enterprise customer vertical, revenue grew by approximately 6% year-over-year in the first half of fiscal year 2023.

This top line expansion was driven by growth in both our cybersecurity and service assurance business line as enterprises continue to demand best-in-class cybersecurity solution as well as visibility solutions capable of helping them to better protect their systems and facilitate the acceleration of their digital transformation.

In addition, we are leveraging our growing set of comprehensive solutions to execute a platform approach, which is also starting to resonate with customers. Michael will provide more insight regarding customer wins within our verticals during his remarks. Now let's move to Slide #8 to review our outlook.

Looking ahead, we plan to continue managing our operations prudently, taking a balanced approach to revenue growth and profitability. Overall, we recognize the current uncertainty in the macroeconomic environment.

We also remain confident about our business prospects and are excited about the market opportunity we are seeing for our NetScout visibility and defensibility platform. With this context, we are reiterating our fiscal year 2023 outlook that we shared with you in early August on our first quarter earnings call.

As a reminder, this outlook target revenue in the range of $895 million to $925 million and non-GAAP EPS in the range of $1.91 to $2.03 for fiscal year 2023. Jean will provide additional color on our outlook in her remarks. In summary, we delivered solid results in the second quarter and first half of our fiscal year 2023.

We are driving clear progress to our strategic priorities, and we remain excited about our core service assurance and DDoS security solutions as well as our new and innovative Omnis solution.

With a unique and powerful platform, deep industry expertise and established customer base, we are well positioned to help customers address the challenges and opportunities of today's increasingly connected and complex digital world. We look forward to sharing our progress with everyone throughout the remaining 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 wins.

In our service provider customer's vertical, we continue to expand our installed base by leveraging both our incumbency and rich portfolio of offerings to better support providers as they steadily advance their 5G build-outs.

As an example, during the quarter, we received a mid-7-figure order from a Tier 1 North American carrier that has consistently increased their 5G-related purchasing from us.

This order was a combination of additional radio frequency propagation modeling, service assurance for their radio access network and other 5G-related products in the migration and capacity expansion of their network.

Importantly, in addition to leveraging our solutions within their mobile business, this customer is also utilizing our service assurance platform within their corporate IT systems. In our enterprise customer vertical, we received a low 8-figure order from a large North American health insurance organization during the second quarter.

Last year, this customer placed a 7-figure order with us for service assurance solutions. And this quarter, they added a full Omnis cybersecurity suite and additional service assurance solution to further utilize our platform's integrated capabilities.

With the convenience of our shared visibility platform and power of our deep packet inspection at scale, we continue to see our comprehensive suite of enterprise solutions attention among our customers.

Finally, as Anil mentioned in his discussion of our recent Threat Intelligent report, we continue to see an increased awareness around DDoS attacks and capacity expansion stemming from the rapid growth in the application traffic and the increasing retent geopolitical situation around the world.

For example, in the second quarter, we received a mid-7-figure order from a large global financial institution that is based in the U.S. and is also a long-standing customer, to extend the DDoS mitigation capacity and upgrade their key data centers to 100-gigabits capacity.

In terms of go-to-market activities, during the quarter, we continue to attend more in-person events. This provided us with additional opportunities to engage with our customers and demonstrate our platform's unique and innovative capabilities.

For example, we recently attended the Black Hat Conference, one of the world's leading cybersecurity trade shows, as well as VMware Explore, a conference for digital transformation and cybersecurity.

At these high-profile events, we engaged with new prospects and existing customers to demonstrate the power of our platform for integrated visibility and cybersecurity. Looking ahead, we plan to attend the upcoming AWS re:Invent conference in November of this year, where we will showcase NetScout's platform as well as our collaboration with AWS.

We have also continued to enhance our customer value proposition by collaborating with other major technology companies and have recently announced several of these initiatives. Through these collaborations, we can help our customers to better address the current threat landscape and navigate the challenges and opportunities of our digital world.

An example is a joint strategic initiative with Ericsson and Swisscom, which was officially announced by Ericsson in October. Through this collaboration, we delivered what is believed to be the world's first solution for cloud-based packet data processing.

By leveraging the strength of each organization, this solution can deliver meaningful improvements in network service assurance, analytics and cybersecurity.

For example, this solution combines Ericsson's and NetScout's technologies to address the challenges of providing end-to-end monitoring and securing 5G networks when in a qualified and encrypted environment.

As a result, Swisscom is utilizing the solution in this newly-deployed cloud-native DLS encrypted 5G network as well as for its existing services to ensure the delivery of mission-critical services with 5G.

Going forward, we aim to continue leveraging the strength of our platform to help our customers better navigate and capitalize on emerging opportunities in today's increasingly connected world. Thank you, everyone. That concludes my prepared 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 second quarter and first half of fiscal year 2023 and provide some additional commentary on our fiscal year 2023 outlook.

As a reminder, this review focuses on our non-GAAP results, unless otherwise stated, and all reconciliations within our GAAP results appear in the presentation appendix. Regardless, I will note the nature of such comparisons. Slide #12 details the results for the second quarter and first half of our fiscal year 2023.

Focusing on our quarterly performance, total revenue grew 7.6% year-over-year to $228.1 million. Product revenue grew 10% and service revenue grew 5.4%, both on a year-over-year basis.

At the end of the quarter, our total backlog was approximately $80 million, consisting of approximately $45 million of fulfillable orders and approximately $35 million of radio frequency propagation modeling projects, with nearly $20 million of the radio frequency propagation modeling amount categorized as deferred revenue from an accounting perspective.

As a reminder, while fulfillable orders are those we believe can be readily converted into revenue upon shipment or fulfillment, the radio frequency propagation modeling projects require certain execution steps in conjunction with the carrier's timing before they can convert to revenue.

Gross profit margin was 76.8% in the second quarter, down 1.5 percentage points year-over-year. This quarter's gross margin was impacted by approximately $15 million of radio frequency propagation modeling projects, which had an average gross margin of less than 30%.

Quarterly operating expenses increased 2.2% year-over-year, mostly due to the return of pre-pandemic activities such as in-person events and travel and partially due to a competitive employment market. We reported an operating profit margin of 23.7% compared with 22.3% in the same quarter last year. Diluted earnings per share was $0.57.

Clarifying earlier statements, I'll repeat, the diluted earnings per share was $0.57 compared with $0.47 in the same quarter last year, representing an increase of 21.3% year-over-year. Turning to Slide 13, I'd now like to review key revenue trends by customer verticals and product lines.

Please note that all comparisons here are on a year-over-year basis, consistent with our other remarks. For the first 6 months of fiscal year 2023, our service provider customer vertical revenue grew 11%, while our enterprise customer vertical revenue grew 6.4%.

During the same period, our enterprise customer vertical accounted for approximately 51% of our total revenue, while provider customer vertical accounted for the remaining 49%. Now turning to our product lines. For the first half of fiscal year 2023, our cybersecurity revenue increased by 14.3% while our service assurance revenue increased by 6.6%.

During the same period, our service assurance product line accounted for approximately 73% of our total revenue, while our cybersecurity product line accounted for the remaining 27%. Turning to Slide 14, which shows our geographic revenue mix.

In the first half of fiscal year 2023, our revenue was more concentrated than usual in the U.S., primarily due to higher revenue related to radio frequency propagation modeling projects from Tier 1 domestic carriers.

Additionally, one customer represented 10% or more of our total revenue in the second quarter and the first half of our fiscal year 2023. Slide 15 details our balance sheet highlights and free cash flow.

We ended the second quarter with $367.1 million in cash, cash equivalents and marketable securities, representing a decrease of $7.5 million since the end of the fiscal -- sorry, since the end of the first quarter of fiscal year 2023. Free cash flow for the quarter was $7.1 million.

As a reminder with regard to share repurchase program activity, we entered into an accelerated share repurchase agreement in our first quarter of fiscal year 2023 to repurchase $150 million of our common stock.

We received approximately 70% of the total shares estimated to be repurchased pursuant to the ASR agreement in our first quarter or approximately 3.3 million shares. We anticipate receiving the remaining approximately 30% of the program shares when the program concludes no later than December 31, 2022.

From a debt perspective, we ended the second quarter of fiscal year 2023 with $200 million outstanding on our $800 million revolving credit facility, which expires in July 2026. To briefly recap our other balance sheet highlights, accounts receivable net was $139.1 million, representing a decrease of $9.1 million since March 31, 2022.

The DSO metric at the end of the second quarter of fiscal year 2023 was 52 days versus 64 days at the end of the second quarter of the prior year and 64 days at the end of our fiscal year 2022. Let's move to Slide 16 for commentary on our outlook. I will focus my review on our non-GAAP targets for fiscal year 2023.

We are reiterating our non-GAAP outlook for fiscal year 2023 that was last presented during our first quarter fiscal year 2023 earnings call on August 4, 2022. As a reminder, for fiscal year 2023, we anticipate revenue in the range of $895 million to $925 million, which implies a mid- to high single-digit top line growth rate.

The effective tax rate is anticipated to be in the range of 20% to 22%, assuming between 73 million and 74 million weighted average diluted shares outstanding, which includes the estimated impact of the $150 million accelerated share repurchase program.

With a partial offset for stock compensation dilution, we expect non-GAAP diluted earnings per share to be between $1.97 and $2.03. To reiterate and clarify from previous comments, it's $1.97 and $2.03 for the earnings per share guidance. I'd also like to offer some color on the second half of our fiscal year 2023.

Assuming the midpoint of our revenue outlook range, we currently anticipate that our remaining fiscal year 2023 revenue will be nearly evenly split between our third and fourth quarters, with expectations for our third quarter revenue to be 1 to 2 percentage points higher than our fourth quarter revenue in the SKU between third quarter and fourth quarter.

With regards to the second half earnings per share, assuming the midpoint of our non-GAAP EPS range, we currently anticipate receiving approximately 60% in the third quarter and approximately 40% in the fourth quarter.

As we have discussed previously, our third quarter gross margin will contain a higher product mix of radio frequency propagation modeling project activities, which has a lower gross margin. That concludes my formal review of our financial results.

Before we transition to Q&A, I'd like to quickly note that our upcoming IR conference participation is listed on Slide 17. Thank you, and I'll now turn the call over to the operator for Q&A..

[Operator Instructions] We will take our first question from Matt Hedberg with RBC..

Nice consistency in the quarter here. You're reiterating guidance for the year, which is nice to see. Jean, thanks for the added color on expectations for the second half just there.

With a lot going on, maybe could you talk to some of your confidence points for the second half?.

Sure. I think as we mentioned in our earlier comments, that we've been seeing good activity across a wide variety of the trends that we participate in, the trends being 5G. So we have some 5G projects that have come in from Tier 1s. We have still calibration that we are executing on, which is in part of the backlog.

In the enterprise, we have been seeing digital transformation and some customers going through what I would call a not necessarily a refresh but maybe a reconsideration phase of things they had purchased in the past that didn't work out as well in this much more complicated digital environment.

And then finally, within security, as mentioned, we have been updating the road map and coming out with the new products that Anil talked about as well as the initiation of the Omnis. So we have a combined portfolio of solutions now that works well for 5G digital transformation, the threats of cybersecurity.

As you'll note, the backlog in the shippable portion and that, again, is the portion that was not available -- was not able to be shipped at the end of the quarter but probably has already been shipped and will convert into revenue was still consistent with the prior year -- prior quarters entering backlog.

The only thing that changed was the execution of calibration. So when we look forward to the end of this year, at this point, we are comfortable with reaffirming our revenue ranges..

That's great. And then could you talk to federal business in the quarter with the fiscal year-end? I think you've previously commented to most of those projects being funded.

Just anything around federal worth pointing out for us?.

I think as Jean is looking at this, Matt, it was better than last year but that's because last year was not that great. So I mean, there is still uncertainty in terms of the project budgets and timing and the fiscal year was just over.

But since it's not a big portion of our total revenue, I think this is probably not -- I mean, there are other factors which could impact things in the future than the federal business..

Yes. Just to add, some numerics to that. I would say basically, the service revenue in the U.S. federal government, so the portion that is support, has been consistent on a year-over-year basis, which is good, which means that they're still using our products and they still want to use -- still want to have support on those.

Product revenue was probably slightly flat with what it was in Q2. So overall, on a dollar basis, it was relatively consistent with prior year's Q2. That's the U.S. federal government piece..

We will take our next question from James Fish with Piper Sandler..

I want to follow up on the question before that, before the Fed. With the reiterated guide, I just want to understand the puts and takes you're thinking about here, given the macro environment, especially on the international side where budgets are a little bit tighter, you have elongating sales cycles. Obviously, you got a benefit from the 5G builds.

But we did hear from some of your networking peers that have cited weakness here already. Just trying to understand how you guys are thinking about order growth in the back half of the year..

So Jim, thanks for the question. So I think there's another dynamic plays out on our business in addition to the very good backlog we had entering this year. When we look at the networking peers, they are mostly infrastructure companies, and we have a trailing effect on both spending cuts and spending opportunities once the network build-out is done.

Then you use tools. So I think if we see some headwinds on the macroeconomic side, we'll probably see that, and we'll update that at the end of the fiscal year. So we feel comfortable the range which we have allows us to manage this and with all the other pipeline and other information and visibility we have.

And despite some of the things you are seeing in the international side, we, at this point, feel comfortable with the guidance..

That's helpful, Anil.

Obviously, still elevated backlog, I'll agree, but how are you guys thinking about that backlog returning to kind of normal as supply chain does start to open up? Is it by fiscal year-end of '24, earlier or later? And then Jean, it sounds like there was a little bit more professional services mix this quarter in the service revenue.

Is that right? Or is it just kind of the natural flow-through of maintenance starting to pick up as products grew last year?.

What is flowing through this quarter in service revenue is something that happens almost every year. We have back maintenance people that sign up for contracts after their original due date. And so any period of service that you've provided flows right through revenue at that time.

So I think in Q3 of last year, we had some -- a lot of back maintenance or some back maintenance. Q2 of this year, I would say the delta between -- the delta in back maintenance was probably maybe attributed to about $5 million..

Okay. And then on the backlog timing, like when we go back to the -- I think the historical range was about $25 million, $30 million historically, where you sit around $80 million today.

I guess are you guys thinking about it as like a 6-quarter or 8-quarter kind of time frame?.

Well, I think overall, it will be somewhere in between because of hopefully higher growth because of our cybersecurity initiatives. So some of the new initiatives, even though this year, we feel comfortable with the guidance, a lot of the new things have not really significantly contributed to this.

And we have a general feeling that cybersecurity is less prone to macroeconomic challenges than service assurance. So the investment we made last year, so our plan is that our backlog will be somewhere between the traditional one, which we had, like you talked about $30 million, $40 million to the elevated one, mainly because of calibration.

I mean, calibration business is still possible this year, but nowhere will be at the size of what it was last year. So it's hard to predict what the backlog is going to be like this or lower or higher in the next 18 months. But I think when we talk about the guidance for next year, it will reflect our insights into that..

We will take our next question from Kevin Liu with K. Liu & Company..

Just wanted to clarify some comments around kind of the macroeconomic impacts on your business.

Have you guys seen anything to date in terms of delays or project cancellations that are concerning at all? And then I was just wondering, with cybersecurity maybe being a little bit more insulated, whether you're expecting your service provider business to hold up fairly well..

Overall, I think we see, Kevin, that so far, at least, we have not seen any delays which has got to my attention any big deals or anything. And how this changes over the next 3, 4 months, we'll see.

But we are still benefiting here and there from the -- we have very little supply chain problem because being a corporate company and the way we package our software and we have some partners, we take care of that.

So we think that we might -- even in this environment, we might benefit from some supply chain dollars coming from other vendors to us in this last quarter. So right now, I think we are not seeing those effects.

But like I said earlier, that we'll have to carefully watch it and make -- and when we provide the guidance for next fiscal year, we will keep that into account. But so far, luckily, we are not seeing any real issues. We keep hearing in other earnings calls, but fortunately, we are not seeing anything so far..

Understood. That's good to hear. And then just on the expense side of things, you guys talked about things starting to return to kind of pre-pandemic types of spend with in-person activities.

Just wondering as we look out to next year and maybe in the future, do you feel like this is kind of a more normalized baseline that should recur from year to year? Or do you think there's even more kind of interest in activities that will continue to pick up and that we should account for?.

I would say that the amount of travel is not as high as we would have originally thought in this fiscal year. So next year, I could see where some travel would repopulate in the P&L.

Also depending on economic times and as everyone -- a lot of people have experienced significant compensation rate increases, we would have to see if that occurs in our next fiscal year also. Barring that, those 2, off the top of my head, I don't see any other operating expenses that would come through.

And so as the company generates incremental revenue, we will continue to have traditionally strong flow-through to our operating margin and our earnings per share..

Great. Congrats on the quarter end..

We have no further questions on the line at this time. I will turn the program back over to Tony Piazza for any additional or closing remarks..

Thank you, operator. That concludes our call for today. Thank you for joining us, and have a good day..

This does conclude today's program. Thank you for your participation. You may disconnect at any time..
