Ladies and gentlemen, thank you for standing by. And welcome to the Ribbon Communications First Quarter 2018 Earnings Conference Call. [Operator Instructions]. As a reminder, this conference is being recorded on Thursday, April 26, 2018. I would now like to turn the conference over to Sara Leggat, Head of Investor Relations. Please go ahead, ma'am.

Thanks, Sarah. Good morning and welcome to our First Quarter 2018 Financial Results Conference Call. On the call with me today, are Fritz Hobbs, President and CEO; and Daryl Raiford, CFO. Today's press release and supplemental data have been posted to our IR website at ribboncommunications.com. A recording of this call and a transcript will be available on our IR website shortly after the call. Please note that during this call, we'll be making forward-looking statements regarding items, such as business, strategy, future market opportunities and the company's financial outlook. Actual events or financial results may differ materially from these forward-looking statements and are subject to various risks and uncertainties, including, without limitation, economic conditions, market acceptance of products and services, the timing of customer purchasing decisions, revenue recognition, our ability to successfully integrate GENBAND and Sonus, difficulties leveraging market opportunities and the impact of cost-containment efforts. A discussion of these and other factors that may affect our future results is contained in each of Ribbon Communications' latest annual, quarterly and current reports on Form 10-K, 10-Q and 8K, and in today's earnings release, all of which are available on our IR website. Additionally, many of the risks and uncertainties could cause actual results to differ materially from these forward-looking statements. While we may elect to update or revise forward-looking statements at some point, we specifically disclaim any obligation to do so. During our call, we'll be referring to certain GAAP and non-GAAP financial measures. Reconciliations of historical non-GAAP measures to comparable GAAP financial measures are included in our presentation on our website and in our earnings press release issued today. With that let me turn it over to our President and Chief Executive Officer, Fritz Hobbs.

Thank you, Sara, and good morning to everyone on the call today. First quarter was our first full quarter operating as Ribbon Communications. We're pleased with our performance including non-GAAP revenue of $135 million, and adjusted EBITDA of $1 million. We quickly established Ribbon as an innovative technology provider, meeting the customers' demand for secure, real-time communications. Specifically, we have brought our capabilities and solutions to the market and are leading the network modernization trend for both service providers and enterprises. On our last call, I stated that our top priority for 2018 is to ensure that Ribbon turns in a highly efficient manner -- runs in a highly efficient manner, and that we capture cost synergies as part of the merger integration process. We believe that driving meaningful profitability will lead directly to increased shareholder value. We have operationalized over $65 million in annualized cost synergies to date, which exceeds the target we shared with you all at the time of the merger. Following our solid first quarter performance, we believe we are well positioned to deliver against our previously provided guidance of $75 million of -- in adjusted EBITDA for the fiscal 2018. This morning, I'd like to update you on our business integration and the other strategic priorities outlined during our last call. I will then turn the call over to Daryl, who will discuss our first quarter financial results in greater detail. Our team has worked tirelessly to ensure that our integration efforts have been as seamless as possible for our customers and partners. We've already operationalized many of our necessary actions and are on track with our remaining integration efforts. We are driving efficiencies and realizing synergies across our cost structure. On the cost of goods sold front, we are optimizing our supply chain, operations…

Thanks, Fritz, and good morning, everyone. I'm going to review our non-GAAP financial results for the first quarter 2018 and then provide commentary on our outlook for the remainder of 2018. The slides on our IR website have the details regarding our historical financial performance. Our reporting framework is consistent with what we have presented in prior periods. I encourage you to get these materials from our IR website. As a reminder, when I refer to non-GAAP in conjunction with a financial metric, these financial metrics exclude the effect of purchase accounting and other items detailed in our earnings materials. Our non-GAAP financial metrics are reconciled for you at the end of both the today's press release and our earnings presentation, and both are available on our Investor Relations website. Turning to the first quarter, Ribbon produced a solid financial performance that exceeded our expectations. We are pleased with our sales performance as our sales team kicked of the new year armed with a combined Ribbon products and solutions offering directed at both our large installed customer base and our rich pipeline full of new prospects. We believe we have a unique value proposition of real-time communication products offering in software, hardware and cloud-native solutions. In summary terms, our first quarter 2018 non-GAAP financial results were as follows, total non-GAAP revenue was $135 million; gross margin was 57%; loss per share was $0.04; and adjusted EBITDA in the first quarter of 2018 was $1 million. We view these results as a positive indication of solid business performance. Ribbon's first quarter non-GAAP revenue of $135 million exceeded our initial outlook by $10 million as we benefited from improved product sales due to higher order volume and stronger professional services revenue from accelerated project completions. Ribbon's first quarter non-GAAP adjusted EBITDA was…

Thank you, Daryl. In summary, by executing our business integration, we have meaningfully improved our financial profile while moving forward with a commitment to provide innovative solutions, outstanding service and worldwide reputation representation for our customers. This year will provide a sound foundation for Ribbon going forward on many fronts. As our customers continue to navigate the trends in the industry, we have the products, resources and commitment to help them succeed. All of us at Ribbon are excited about the future. I would now like to ask the operator to open the call up for questions-and-answers.

[Operator Instructions]. Our first question comes from the line of Dmitry Netis with William Blair & Company.

My question is kind of twofold. First, I know you don't guide quarterly, but can you give us a little bit of a kind of view into how you expect the revenue to project as you go through the next 3 quarters? Is there any seasonality sort of built in here? Do we get any choppiness in revenue? Was that a steady kind of sequential -- I'm sorry, well, I suppose it's sequential off of Q1, but give us a sense how to think about the progression as you go through the year?

Well, historically the pattern has been that we have a stronger second half. And we don't see anything that indicates that our history is going to change, so we feel that, that's a good way to think about it. But beyond that, it's -- again, it's a chunky business in many regards but basically, we would suspect or expect that the second half will be stronger.

Okay. And usually -- typically your Q2 is better than Q1? Is that a fair assumption?

It is true that typically the first quarter is -- Dmitry, this is Daryl. It is true that the first quarter is seasonally the lowest quarter.

Okay. Very good. And then second question on gross margins. It was a little, I suppose, below my estimate, but I wanted to see how you're thinking about that gross margin as you move through the year. If you could double-click on that and tell us how it plays out as you move forward? That would be great as well.

Well, we are happy with our gross margin this quarter, and we do believe that as cost synergies manifest themselves through the year that, that will be improving in conjunction with our other financial metrics like OpEx and things like that.

Can you give us a little bit color of what drove -- in December it was 61.5%, you went to 57%. What was some of the elements of kind of the lower gross margin? I get the leverage as you built volume and top line revenue, but was there anything specific that -- COGS or anything else? Some product lines...

No, there is no...

That kind of contributed to a lower margin that you intend to maybe take out as you go through the year given the kind of 10% decline on revenue, as you sort of rationalize your portfolio. Is there anything you can give us -- to give us confidence as that margin will build up as you cleanup some of the products or anything else that's going on there?

I think you hit on the major contributive factor, which is in the fourth quarter our non-GAAP reported revenue was $169 million. Seasonally the fourth quarter is always very high and we do get a lot of leverage across that, and that did yield the margin that you quoted. This quarter, we're reporting $135 million or nearly -- $135 million on a sequential basis reduction, which we expected in terms of seasonality. And that revenue coverage across the fixed cost base is the principal contributing factor.

And maybe a couple more, if I may. On EBITDA, you came in $11 million higher than guidance, which kind of gives you a better view into that $75 million target that you have for the year. Anything -- again, is there anything that we should be thinking about as you progress through the year as far as choppiness in this EBITDA progression, or is it sort of a steady buildup and you get kind of the most benefit in Q4?

Well, we are very pleased with EBITDA, as I said moments ago, the higher than expected from the initial outlook revenue did disproportionally and benefit our EBITDA, and we're delighted with that. That is demonstrating the scale that we're -- then the leverage that we're building in the business. Moving forward, I would not expect that we take a -- as we look over the quarters and just seasonally, I would not expect that we take a step backward on that we continue to progress towards $75 million -- our firm guidance on the $75 million for the full year.

Okay. My last question is more of a product related, if I may. I wanted to get a sense of how session border controllers are doing versus maybe a media gateway business. Anything you can talk to -- that trajectory sequentially or on a year-over-year basis? I suppose, whichever way you want to address it, that'll be good, but just sort of trying to understand, how your legacy product is doing relative to growth?

Right, and I understand that, just as an overview, we said before and we do still -- we maintain at that. We sell solutions to our customers and in the network modernization or network transformations space, the solution mix is highly dependent upon the individual customers, specific network configurations and what types of products they may need, as part of delivering the network transformation solution. With that said, on a pro forma basis to this time last year, softswitch and media gateways were flat and SBCs were slightly up.

Our next question comes from the line of Mike Latimore with Northland Capital Markets.

Just in terms of the revenue mix, products and service, can you give some general guidance on how you think about that mix, whether it's this year or just longer term?

General guidance and how we think about the mix. This year's quarter achieved a revenue on a non-GAAP reported basis of $60 million, and that is in line with last year pro forma, and services were just slightly less and that's just related to completion timing and the recognition of professional services compared to the prior period. So the mix, we expect to remain roughly in line with what the companies have experienced in the past. There's nothing -- no substantial factor that would drive a material mix change.

Got it. And then on the -- you sort of called out Kandy and then the SBC as a service, carry the services, maybe growth areas. Can you give us a little color on -- as a percent of revenue, what were those categories or as a percent of bookings? And then some color on what kind of growth rate you expect from that group over time?

Well, we are encouraged with the funnel and the opportunities that Fritz set out, that are within proof of concept and we're moving forward under contract with. The revenue in 2018, we expect to be immaterial or -- and in terms of Kandy [indiscernible] Ribbon Protect. Our growth rates we're -- we are evaluating those and watching those. It depends on the robustness of the funnel and the closure rate during the second half of 2018, and the deploy rate from our customers. But we do expect the revenues from both of those on a -- to the -- in total to be less material or not material to the -- as a percentage to the total company revenue.

And just last on the enterprise segment. Do you see that kind of growing as a percent of revenue or staying kind of roughly where it's been?

We do. On an as reported non-GAAP, as reported basis, our -- it's in our Investor Day. You'll see that our enterprise to service provider mix did reduce. Well, and that's with the addition of the GENBAND legacy business within that and so we're doing a compare back to without the GENBAND business. We do expect that financial metric of 14% for enterprise as a percent of revenue to be -- to naturally grow some, as we continue to pursue our enterprise strategy.

[Operator Instructions]. Our next question comes from the line of Mark Kelleher with D.A. Davidson.

If you look at your couple of key partnerships, Verizon and Microsoft, how does the revenue play out to those 2? Is it lumpy? Is it a consistent growth? Is it seasonal? How does the partnership between Microsoft and Verizon play out in revenue?

The partnership with Microsoft is primarily related to supplying SBCs, and they -- our lower capacity SBCs, and that is a more steady channel relationship. Verizon is a different situation, the Sonus legacy company did report approximately $10 million from sale of software to Verizon around SBC -- the SBC software product and virtualized product in the third quarter of 2017, to the extent that more software sales like that occur. You know they could be -- and they are -- that could be material as deployments occur, then that would be more lumpy. It's not really a channel business, it's more of a software sale. So it's -- they're not really related to each other very well, with Microsoft being more channel related and Verizon being more service provider deployment.

And you talked about rationalizing your product portfolio. I guess that relates to some of the overlap in the SBCs between GENBAND and Sonus. Is that right?

Yes, that is a good size component of that. We did say last quarter, that we've undertaken a streamlining of our product portfolio to reduce or eliminate products that do not meaningfully contribute to profitability. And that process is ongoing. SBCs -- GENBAND SBCs would be a -- we are evaluating that and looking at that and working with customers on it as an example.

Okay. And I know in the past you've talked about the opportunity for industry consolidation. Can you just maybe update us on your thoughts there?

Well, I think that the -- what's becoming increasingly clear to me is someone who's relatively new to the industry, is that there's a -- there really is an interesting development going on here which is, as the larger and larger customers, they want broader and broader reach of product line, broader and broader geographical reach, and we think that we are actually uniquely positioned in that regard, because we really have been doing this for many years on both of the prior companies. So we think our global footprint is going to be very relevant. So that means that there may be -- we think and I think, there'll be opportunities to either collaborate with some of the midsized companies, maybe there'll be some acquisition opportunities, but we really are open for discussion anywhere along any of those lines, because I do think our built-in asset of being involved across the world is really relevant -- increasingly relevant in the way this industry is going.

There are no further questions registered. I'll turn the call back over to the presenters.

Well, thank you everyone, for joining our call this morning. As we've said, Ribbon is very pleased with our results. We look forward to speaking with you as we progress through the months of May and into June. Fritz and I will both be at a number of different conferences and we hope to be able to see you then. Thank you.

Ladies and gentlemen, that does conclude the conference call for today. We thank you all for your participation, and ask that you please disconnect your lines.
