Thanks, Lynne. Good morning and welcome to our fourth quarter and fiscal year 2017 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 the call, we will 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 risk and uncertainties including, without limitation, economic condition; market acceptance of our 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 in contained in each of Ribbon Communications' latest annual, quarterly and current reports filed with the SEC and in today's earnings release, all of which are available on our IR website. Additionally, many risks and uncertainties could cause actual results to differ materially from any 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 will be referring to certain GAAP and non-GAAP financial measures. Reconciliation 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. Good morning to everyone on the call. In late October 2017, we completed the merger of Sonus and GENBAND, which transformed our business. We rebranded our company as Ribbon Communications, which signified our role as an innovative technology provider, positioned to meet the growing demand for secure real-time communications. I'm encouraged by the future outlook for Ribbon as we are well-positioned to lead the network modernization trends for both service providers and enterprises. In December 2017, I became the CEO of Ribbon. I believe I can leverage my prior executive experience driving transformational change and generating significant long-term shareholder value. During my first few months at Ribbon, the extended management team and I've been focused on reviewing our go-to-market strategy, evaluating our product portfolio and driving integration activities and related cost synergies. I'm very impressed at the level of talent that has come together to create Ribbon. The executive team surrounding me – starting with David Walsh, GENBAND's former CEO, Daryl Raiford, our CFO and former CFO of GENBAND – is made up of industry veterans with deep domain expertise, representing a balanced mix of the best of both companies. We retain key management such as Mike Swade to lead sales, Patrick Joggerst to lead marketing and business development. Additionally, our operations and services are led by Steven Bruny, a highly experienced industry executive. Kevin Riley who has overseen the successful SBC product development efforts at Sonus is our current CTO. And we welcomed Tony Scarfo back to the ribbon team in January to lead our combined products and R&D functions. Susan Villare, formerly interim CFO for Sonus, leads our financial planning and treasury. And John McCready continues to lead strategy and corporate development. This is an exceptional team. I'm also very pleased with the combined company's…

Thanks, Fritz. And good morning, everyone. I'm going to review our non-GAAP financial results for fourth-quarter and full-year 2017 and then turn to commentary on 2018. As a reminder, our non-GAAP financial results are reconciled for you at the end of both of today's press release and our earnings presentation. Both are available on our investor relations website. Our full-year results include 12 months of Sonus operations and two months of GENBAND operation. 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. I will also use the term pro forma, which means the combination of the respective results of Sonus and GENBAND as if combined at the beginning of the period presented. Overall, we had a very exciting quarter with the launch of Ribbon Communications on October 27. Beginning immediately post-close, our sales team began to aggressively promote the value proposition of Ribbon's secure real-time communications software, hardware and cloud native solution. Our merger integration plans kicked off in earnest immediately and we made substantial progress. And importantly, Ribbon's fourth-quarter revenue, gross margin and earnings metrics exceeded the guidance we provided externally during our third quarter earnings call on both a standalone and a combined basis. On a non-GAAP basis, our fourth-quarter 2017 total revenue was approximately $170 million. Gross margin was 61%. Operating expenses were $80 million. Earnings per diluted share was $0.27. And adjusted EBITDA was $28 million. The acquisition of GENBAND was immediately accretive to Ribbon. For the full year 2017, on a non-GAAP basis, total revenue was $353 million. Gross margin was 66%. Operating expenses were $202 million. Diluted EPS was $0.51. And adjusted EBITDA was $41 million. Our fourth-quarter non-GAAP revenue benefited from stronger-than-expected session border…

Thank you, Daryl. In summary, while we face near-term market challenges, I feel confident that both our market position and expanded global reach will allow us to take share and benefit from cross-selling opportunities over the long term. We will continue to invest in our core products and new cloud-based initiatives, while we are being highly disciplined on our cost structure, driving cost efficiencies throughout the organization. In addition, our balance sheet gives us the flexibility to further consolidate the market, to drive both revenue growth and financial scale. Reflecting on the achievements of Ribbon over the last three months, I personally want to thank all the employees of Ribbon for a solid fourth-quarter 2017 financial results as it was indeed a very busy quarter – closing the merger, delivering on our guidance, and commencing our integration and restructuring initiatives. All of us at Ribbon are excited about the future. I would now like to ask the operator to open the call for questions and answers.

Thank you. [Operator Instructions]. And our first question comes from the line of Dmitry Netis with William Blair. Please proceed.

Hi, guys. This is Steven Sarver in for Dmitry. So, you mentioned that you're still seeing challenges in North America. I guess relating specifically to Verizon and AT&T, what are you expecting from those two customers in 2018?

Good morning, Steven. This is Daryl. How are you? It's good to speak with you. We do expect, specifically to Verizon and AT&T, while we don't really speak to the customers to that much definition, we do expect some dampening of their demand in the near term, at least the first half of 2018.

Okay. And then, just relating to the guidance, you said you expect the first quarter pressure to persist throughout 2018. Are you guys taking more of a conservative stance and you don't have that much visibility and you just want to be a little bit more conservative? Or how do you feel about the rest of the year?

Well, Steven, stepping back from a big picture, first, you see the same companies in the space that we see, bringing down their 2018 guidance. We're participating in the same space as these other companies. Second, you're reading the same market analyst reports that we're reading as well. And our account managers are out with our customers every day, gauging the buying behavior and hearing what they expect in terms of their purchasing patterns and their buying behavior and we're taking that into account. And, fourth, we have said that we – our intent is to transition the GENBAND SPC customer base to the Sonus SPC customer base. And we believe that that is a good opportunity for us in the long term, but in the near-term that does take some time to transition, as Fritz said, and it takes a little bit of a time for the customers to certify that in their labs. So, taken that altogether, from the space picture, from the market picture, what we're hearing from our customers, we do expect at least through the first half for it to persist and then we'll be watching the second half closely.

Got it. And then, one more, if I may. Just, Fritz, I was just wondering. Since you've taken over as president and CEO, has anything changed in the strategy after the merger close?

No, I don't think. I think the opportunity that I've seen being exposed to this for the first time is, obviously, we have a very strong balance sheet. We've got a company that can generate earnings and cash. So, I think the whole approach to looking at the world with some firepower behind us in the financial sense, I think, is a very positive. It might be something we've emphasized even more than we might have three or four months ago.

And our next question comes from the line of Mike Latimore with Northland Capital Markets. Please proceed.

Hey, guys. This is Nick Altmann on for Mike. Thanks for taking our questions. Just a couple regarding Kandy. Can you guys just first talk about your plans for Kandy this year? And maybe give some color on what additional services you'll be adding?

This is Fritz, Nick. I'd like to have – Myk Konrad is with us who is the head of consumer – customer relations. He has a very good view on this and maybe he could speak to it. Gets over my paygrade pretty quickly.

Hey there, Nick. This is Myk Konrad, VP of product management here at Ribbon. And from a Kandy perspective, I think your question was around what new things we'll be adding. So, I think you can expect us to keep putting out new features and functionality along the two lines that we've been talking about on Kandy. On the UC-as-a-service front, the other one on the CPaaS front. And as I think both Daryl – Daryl mentioned earlier we do believe that there is a lot of upside for us on the CPaaS front going forward. So, hopefully, you'll be hearing about that over this next year.

Got it. okay. And just in terms of the go-to-market strategy with Kandy, do you guys have any key distribution partners there? And then, I guess, a follow-up just in regards to the CPaaS side of things, how much focus is on the developer channel?

So, we do have some key distributors that we are working with. We'll be announcing those more as they come to fruition. And from a developer perspective, obviously, to have a – to get really deep in CPaaS, you need more developers and we are working with ISVs on that – independent software vendors.

Got it. Thank you.

Thank you. [Operator Instructions]. And our next question comes from the line of Mark Kelleher from D.A. Davidson. Please proceed.

Great. Thanks for taking the questions. Is it possible to break out the revenue contribution from GENBAND in the quarter, the two months?

Yes. It is possible. And good morning. Hey, it's nice to speak with you. The revenue contribution from GENBAND for the two months in the quarter was $92.4 million.

Okay, great. And then, I'm just trying to reconcile some previous comments that were made at the time of the deal announcement. Generally, the two companies – correct me if any of this is wrong; that's why I'm saying it – generally, if the two companies were generating $25 million in EBITDA per year, the thought was you could put that together, you'd get $50 million and then get $50 million of cost savings to get to $100 million. So, you're giving guidance for $75 million. I'm just trying to – and you said you're ahead of schedule in these cost savings. I'm just trying to reconcile $100 million to the $75 million. Is there something I'm missing?

Absolutely. It's a good question. Our comments in May and June of last year and we maintained through all of 2017 was that we expected to end 2018 on an exit run rate of $100 million of adjusted EBITDA. And we are fully – we believe that we are fully on track for that. The $100 million is derived from as if all of the combination synergies that we're undertaking as of right now would have been in place at the first of this year. That yield us $75 million – because they're not. That yields a $75 million adjusted EBITDA outlook, but it does correspond completely to the $100 million we have said before.

Great. That's very helpful. And then, you talked about the transformation of GENBAND customers over to the Sonus architecture, is there more of a headwind there than you had been anticipating? What's the dynamic there in terms of sales impact?

No. It's not more than we're anticipating. We did say on October 30, and we've made the remarks before, that subsequent to the merger announcement where Sonus was to acquire GENBAND, the GENBAND SPC sales demand did take a bit of a pause, which was natural if you're merging with an SPC company. We are working very aggressively, now since the merger has closed, to expose our worldwide GENBAND customer base to the Sonus SPC product line. We feel it's a very strong lineup. We're very excited about it, but it does take some time to introduce that, to get that into network planning and to get that certified and into the pipeline.

Okay, great. Thanks.

Thank you. And there are no further questions at this time.

Well, thank you, everyone. It was a pleasure speaking with you today and we look forward to speaking with you in the future.

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