[Bruce McClelland, executive]

Great. Thanks, Joni. Good morning, everyone, and thanks for joining us at this new time today to discuss our Q1 results and outlook for the year.I'd like to start with a few comments on the major announcement we just released with Verizon this morning. As I've mentioned on recent calls, there's a significant opportunity with telecom service providers and large enterprises, including the U.S. Federal Government to complete the replacement of legacy TDM voice switching platforms with modern cloud-based solutions. There's a strong ROI for our customers with multiple benefits, including improved overall quality and reliability of the service, significant cost savings from lower power consumption and cooling requirements, a reduction in facilities and floor space that can be repurposed to meet the exponential growth in data consumption for mobile and broadband services and lower engineering and operations effort needed to manage this complex network, all while significantly reducing the environmental footprint made from providing this critical communication service.We're very excited about this new multi-year program with Verizon. It's an extension of the ongoing work we've been doing together, but on a much larger scale. Ribbon will provide both product and professional services to rapidly decommission legacy central office equipment while fully maintaining current services and features. The initial deployment phase of the program will be over the next 3 years, leveraging our full portfolio of virtual and cloud-native call controllers and session border controllers, advanced analytics, line access and universal media gateways. We expect the program to generate over $300 million in revenue for Ribbon over that period, with potential for follow-on programs to continue to support Verizon's efforts in building the most advanced networks.We've worked closely with the Verizon team to reduce the implementation cost by defining a focused large scale project that has economy of scale benefits. This is a major endorsement of both Ribbon's portfolio and expertise in the migration of these complex communication networks. The measured approach Verizon is taking to migrate services and preserve significant revenue streams is applicable to practically all our other service provider customers, where we aim to develop similar programs and generate significant benefits from this cloud migration.Now on to our first quarter 2024 results. We had an excellent first quarter where our strategy to leverage our long-term relationships to diversify and grow our business continues to pay off. Profitability improved significantly year-over-year and exceeded the high end of our guidance range with adjusted EBITDA of $12 million. We benefited from a favorable mix of sales to customers in the quarter, particularly in the EMEA region where sales increased 24% as compared to the first quarter last year. The higher sales in EMEA resulted in strong gross margins exceeding 40% in the IP Optical segment as well as the seventh straight quarter of year-over-year sales growth. This includes customers across a number of markets including service provider, defense and critical infrastructure.Gross margin in the Cloud & Edge business was also strong in the quarter, primarily due to continued growth in the enterprise market with product sales increasing 15% year over year. This includes a number of voice modernization projects with U.S. government Federal agencies. The strong gross margin and reduction in operating expenses of 5% year-over-year contributed to earnings exceeding the top end of our guidance for the quarter.Adjusted EBITDA over the trailing 12 months increased to $105 million for the company, a major improvement trend over the last several quarters. While lower spending from U.S. Tier 1 service providers continued to impact our Cloud & Edge results with sales declining 11% year-over-year this quarter, with our new Verizon program and the potential for similar engagements with other customers, we believe we've reached a low point and expect solid recovery in the business. We expect the new Verizon program alone to underpin this business for the next several years.This quarter, we also continued to increase the software content of our product sales, growing from 25% to 29% year-over-year increasing margins. The continued growth in enterprise has been a key driver behind the higher software sales, improved margins and solid earnings contribution. Overall, company sales in the quarter were at the lower end of our guidance with a few million dollars of equipment in transit at the end of the quarter and site readiness delays with a few smaller deployments for rural customers in the U.S.Now a little more detail on each of our operating segments. Building on the momentum from the second half of 2023, IP Optical Network sales increased 9% year-over-year in the first quarter, with the majority of the growth coming from the EMEA region. This resulted in stronger margins for the segment consistent with the previous quarter at 41% and a significant improvement of $17 million in adjusted EBITDA versus the first quarter last year.In EMEA, the critical infrastructure private networks market segment continues to be a great fit for our portfolio, where high performance and information security are major differentiators. We had a number of expansion projects in the defense sector with customers such as the Israeli Defense Force, the Swiss Army and the Finnish Defense Forces. We also had several new projects with customers in segments such as energy distribution, railways and education. This all complemented ongoing business with a number of service provider customers across the region.In the Asia Pac region, sales to key customers in India, including Bharti Airtel and Tata Teleservices were down only slightly year-over-year and included the full portfolio of both optical transport and IP routing products. There are also very positive signs that Vodafone Idea will complete their long-awaited capital injection with the company's public offering successfully completing this week. They plan to invest aggressively in 5G upgrades and we believe we are very well positioned to be a key supplier as they reinvest in their network, driving growth for the India region in the second half of this year.In the Americas region, IP Optical sales increased year-over-year in Canada and Latin America, while shipments into the U.S. were lower in the Rural Broadband segment this quarter due to customer timing and site readiness delaying revenue recognition into the second quarter.From a product line perspective, sales of our Apollo Optical Transport products were once again strong this quarter, increasing 9% year-over-year. This reflects the stronger mix of these products sold into the EMEA region and is a good start to the year. I expect this optical growth trend to continue as our new Apollo 9400 platform and shipments continue to grow, supporting the highest 1.2-terabit per second speeds available in the market today. We're effectively expanding our addressable market with this platform and are able to better address services such as data center interconnect, complementing the current 9600 platform that's favored by telecom operators. We shipped more than 50 9400 chassis so far and have a pipeline of more than 20 opportunities in process.Sales of our Neptune IP routers grew 2% year-over-year in the first quarter, reflecting lower rural sales this quarter. Also, the first quarter of 2023 where the first volume shipments to Bharti for the 5G Cell Site Router last year, climbing their deployments and building some inventory. We expect this product line to continue to grow with a very good pipeline of new customer opportunities. Overall, IP Optical product and service bookings were 1.07x revenue in the quarter, building backlog for the second quarter.In our Cloud & Edge segment, as expected, the lower spend from U.S. Tier 1 service providers continued to affect our year-over-year comparisons with the reduced spending starting midway through the second quarter last year. Excluding sales to our large U.S. Tier 1 customers, revenue in the first quarter from all other customers grew 1% year-over-year, despite lower overall industry investment. With the new Verizon program, we expect a significant improvement going forward.Enterprise Cloud & Edge product sales increased 15% year-over-year in the quarter with the continued expansion of a major voice modernization project with the U.S. Federal agency. We expect this trajectory to continue in the second quarter. The Cloud & Edge business continued to drive strong profitability due to higher software mix and product and service bookings were good in the quarter at 1.06x revenue.We expect a much stronger second half of the year in our Cloud & Edge business with the continued momentum in enterprise and a significant increase in sales to service providers. This includes the beginning of the new network modernization program with Verizon. We expect initial product shipments from that project to begin in the third quarter and deployment services to ramp as the program accelerates, exiting the year at $100 million per year run rate, once again with this key customer, providing a strong foundation for growth in this segment. We continue to maintain a strong reoccurring maintenance business across our customer base and have approximately 80% of this year's maintenance revenue and backlog or under contract for the Cloud & Edge business as well as for the IP Optical segment.With that, I'll turn it over to Mick to provide additional detail on our first quarter results and then come back on to discuss outlook for the second quarter. Mick?

[Miguel Lopez, executive]

Thank you, Bruce. Good morning, everyone. We were very pleased with our financial performance in the first quarter as we exceeded the high end of our guidance for gross margins and adjusted EBITDA on strong performance by IP Optical Networks in particular. On a trailing 12-month basis, our adjusted EBITDA is $105 million back to levels over $100 million prior to the 2022 supply chain disruption. As always, please refer to our Investor Relations page on the Ribbon website for supplemental financial information. You will also see that we have now included an Excel worksheet to facilitate your analysis.Let's begin with financial results at the consolidated corporate level. In the first quarter of 2024, Ribbon generated revenues of $180 million, which is a decrease of 3.5% from the prior year. Non-GAAP gross margin was 55.1%, which is 700 basis points higher than prior year due to a positive product and regional mix. As you will hear, both business segments had significant improvements in gross margin percentages versus prior year.Non-GAAP operating expenses were $91 million, an improvement of $5 million, or 5% year-over-year, driven by continued reductions in R&D and sales expenses from last year's restructuring efforts. Non-GAAP net loss was negative $1 million, which is a $2 million improvement from the previous year. This generated non-GAAP diluted loss per share of negative $0.01, which is an increase of $0.01 versus prior year. Our non-GAAP tax rate year-to-date was 35%.Our interest expense for the quarter was $6 million consistent with the previous year. Adjusted EBITDA was $12 million in the quarter, which is a great $14 million improvement from last year's EBITDA loss of negative $2 million. This is the best first quarter profit performance in the last three years. Our basic share count was 172 million shares and our fully diluted share count was 175 million shares for the quarter.Now, let's look at the results of our 2 business segments. In our Cloud & Edge business, first quarter revenue was $102 million, a decrease of 11% year-over-year, driven by lower product sales at U.S. Tier 1 service providers. We are increasingly confident that we can grow our revenues for this business segment with the incremental business from Verizon's network modernization program. The Cloud & Edge business had a strong first quarter non-GAAP gross margin of 66%, up about 500 basis points from the prior year. This improvement was driven by an increasing mix of software product sales, which were 68% of total product revenues. The Cloud & Edge business segment continues its steady cash and profit contribution with an adjusted EBITDA of $17 million, or 17% of revenues.Let's turn to our IP Optical Networks business results. We recorded first quarter revenue of $78 million, which was an improvement of $6 million, or a 9% increase versus the prior year. Non-GAAP gross margin for IP Optical Networks was 41%, up about 1,400 basis points from the prior year from 27% in the first quarter of 2023. This resulted in gross profit of $32 million, which is a $12 million or 64% improvement from previous year, mostly driven by lower product costs and better regional mix from EMEA sales. If you recall, 1 year ago, we made sales of our initial long haul optical transport infrastructure equipment to India at lower margins. Adjusted EBITDA for the quarter was a loss of $6 million, which is an improvement of $17 million year-over-year. This is the seventh straight quarter of year-over-year improvement in IPON profitability. We continue to strive for positive adjusted EBITDA for this business segment in 2024 as it continues to grow.Let's now discuss total company cash flows and capital structure. Cash from operations was excellent with a positive $13 million in the quarter. That's now 2 positive cash flow quarters. We used cash in the quarter of $3 million for capital expenditures and our quarterly $5 million term loan repayment. We ended the quarter with $31 million of cash and cash equivalents and increased $4 million from the end of 2023.Our senior term loan balance was at $230 million and the $75 million revolver loan had zero balance outstanding. Per the bank covenant calculations, which include $55 million of our preferred equity and total debt, among other adjustments, we comfortably met both of the term loan covenant metrics in the first quarter. Our bank leverage ratio was at 2.71x, which is within our target range of 2x to 3x. The fixed charge coverage ratio was 1.77x.Speaking of debt, we have started the process of refinancing our capital structure, both the term loan and preferred shares. As part of this process, we have already received a B2 rating from Moody's and a B- from Standard and Poor's, both with a stable outlook. You may have noticed that we rescheduled this earnings call from the afternoon to the morning to accommodate the Lenders kickoff meeting this very afternoon. Assuming stable market conditions, we expect to have our refinancing done in several weeks. We remain confident in the continued support of our financial partners to obtain a flexible and long-term capital structure to sustain a profitable growth.Now, I'll turn the call back to Bruce to provide more comments on our outlook for the second quarter.

[Bruce McClelland, executive]

Great. Thanks, Mick. As I said last quarter, I'm very confident in our ability to continue to grow revenue and improve profitability this year. The new Verizon program will provide a strong foundation for the company with opportunity for similar programs with other telecom operators. We expect revenue from the Verizon program to begin in the third quarter with deployment ramping over time. The improved margin trend over the last few quarters and the strong profitability in Q1 further increase our confidence of achieving our full year guidance.In addition to the recovery in the Cloud & Edge telco business, we continue to add significant new wins with U.S. Federal agencies that are initiating their own voice modernization programs. In fact, we have a very strong and growing global government and defense business that leverages our entire portfolio of voice and data products and a strong professional services practice tailored for this market vertical. The scalability, reliability and information security aspects of our products are significant differentiators and there's a larger market that we are not yet fully addressing. We have made this a strategic area of investment given the large opportunity, particularly in North America and Europe. Globally, the government and Federal market segment accounted for almost 10% of overall sales for Ribbon in 2023.From a portfolio perspective, I'm excited about our innovation pipeline. As I mentioned earlier, our new Apollo 9400 Compact Modular Optical Transport platform is gaining momentum and significantly expands the portion of the market that we can address, including long-haul transport, subsea networking and data center interconnect.While we've already been successful penetrating these markets and have multiple deployments with customers such as Bharti, IPS, Ciena and Telehouse. The 9400 platform has been purposely designed for the unique environmental requirements of these market segments. We conservatively estimate $1 billion increase to our addressable market and are excited about the momentum behind this new product with the industry leading 1.2 terabit per second coherent optics.At the recent Optical Fiber Communication Conference at San Diego, we made a joint announcement with Cisco, highlighting the interoperability between our 9400 platform and the Cisco NCS 1014 platform. Interoperability and optical networking is very rare and is a great endorsement of our open networking strategy. This will enable our customers to stay on the cutting edge of technology without being locked into proprietary solutions.In our IP Routing portfolio, we continue to expand our product line and just completed the introduction of the Neptune 2400 high performance aggregation router. Leveraging a common network operating system, the 2400 is a great fit for middle mile and edge aggregation applications and supports a rich set of IP routing features and capabilities. This allows us to address a growing number of IP services. This 4.8 terabit non-blocking router supports a significant number of 100 gig and 400 gig client side interfaces, making it an ideal platform for a number of high capacity applications with coherent ZR+ optical uplinks.The lens by which our customers manage our portfolio of data networking products is our cloud-native Muse platform. With our customers, we've identified a number of practical applications that can benefit from the power of generative AI. Complex network planning, rapid false isolation and root cause analysis and intelligent network optimization are great examples of the way we are leveraging generative AI to improve our products and differentiate our solutions.So we're off to a solid start in the first quarter and are making very good progress on our key strategic goals, including achieving sustainable profitability in our IP Optical business, returning to growth in our telco voice infrastructure business, diversifying and expanding sales in enterprise market verticals including financial, health care and government information security, and accelerating innovation and capturing cost efficiencies with full integration of our product teams.For the second quarter, we expect sequential growth in both of our businesses. In IP Optical, we expect continued momentum in the EMEA region as well as growth in North America and Asia Pacific. We expect gross margins to continue to be in the high 30s or better. In Cloud & Edge, we expect improvement in the U.S. Tier 1 environment coupled with growth in enterprise as well as the additional U.S. Federal projects. Based on this, for the second quarter, we're projecting revenue in a range of $200 million to $210 million, non-GAAP gross margins of 53.5% to 54.5%, and non GAAP adjusted EBITDA in a range of $20 million to $25 million. Our guidance for the full year remains unchanged, although as I mentioned earlier, we're definitely off to a good start to meet these financial objectives, along with a strong second half.Operator, that concludes our prepared remarks, and now we can take a few questions.

[Operator]

[Operator Instructions] Our first question is coming from Christian Schwab with Craig-Hallum.

[Christian Schwab, analyst]

Congratulations on the big Verizon order. Just a couple questions about that. One, what type of gross margin over time should we assume that, that will be done at? And then as far as the $300 million, 3-year time frame, is that back end loaded, or does that -- I know it's going to start in the second half, but does it step up big in '25? Any color there would be great.

[Miguel Lopez, executive]

So on the gross margin question, we have a mix of product and services that we're supplying to the program. So it may vary a little bit, just depending on the activity in a particular quarter, you know, blended, it's probably a little below the current gross margin level for Cloud & Edge, which is, as you know, high 60s. So it's a little below that just because of the higher content in hardware and services, but still pretty solid, obviously.On the question on kind of the speed and the ramp, we definitely get started in earnest in the second half of this year and kind of achieve full velocity as we get into 2025 and stay at that level for a couple of years, effectively. So this is a pretty extensive program. You can imagine the effort that's required to go into these switching centers and switching out equipment seamlessly and everything. So there's quite a -- it's a pretty long process, which is great. It's going to be a great program.

[Christian Schwab, analyst]

Great. And then I just have one quick follow-up. Just on the real broadband stuff, you know, other people inside the space are kind of suggesting that, that really doesn't kick off till Q1 of '25. But it sounds like maybe some of the things that you're working on may start a little bit sooner than that. Did I hear that incorrectly? Or how should we be thinking about that?

[Miguel Lopez, executive]

Yes. So the BEAD program, the $42 billion BEAD program doesn't really start until next year timeframe. In fact, I think for us it's kind of second half of next year. About half of the world broadband programs we have in process today are assisted in one form or fashion from other federal funding programs like RDOF and those sorts of programs. So we've got a nice base, a nice funnel of activity there, even prior to the larger funding program coming in.

[Christian Schwab, analyst]

Fantastic. No other questions.

[Operator]

Next question today is coming from Dave Kang from B. Riley securities.

[Dave Kang, analyst]

My first question is the follow-on on that Verizon win. So Verizon was a major customer. So just wondering, what's the delta between the old program versus the new one?

[Bruce McClelland, executive]

Dave, so this is obviously a major step up from the current run rate we're at today. I think I mentioned in the remarks that we'd exit the year at greater than $100 million per annum run rate with them, which is maybe where we were a few years ago, you know back when other programs were very active. So we get back to that level or better in the next few years here as this program really starts to gain energy.

[Dave Kang, analyst]

So like, you know, back to where Verizon was several years ago, but what was the run rate in recent years, like, in the last year or 2? Were they like $50 million going to $100 million or any color there?

[Bruce McClelland, executive]

Dave, yes, given they're a 10% plus customer, we actually break them out in our [ QNRK ]. I can't remember the exact number for '23, but I think it was in -- Mick, do you remember what the number was?

[Miguel Lopez, executive]

It was 10% or 11%.

[Bruce McClelland, executive]

So, [ 75 million, 80 million ], yes.

[Dave Kang, analyst]

Okay. All right. And then just a question on India, if you can talk about, you know, what's going on there. And also you mentioned the Vodafone Idea. What kind of opportunities do you see? Which products? Any color there would be great.

[Bruce McClelland, executive]

Yes, absolutely. So in the first quarter, sales in India were essentially flat to what we did a year ago. And if you recall a year ago, we had a really good quarter. We started to step up the deployments in India. I think we grew 30% total last year. So it's good to see that business continue to be solid. The key customers there today are names like Bharti and Tata and a little bit with Reliance and a few others.Vodafone, as you recall is the third largest mobile operator in the region and needed to refinance their balance sheet, which has been a discussion now for probably a year. It was great to see, actually on Monday this week, they closed the equity raise process that they were doing, the secondary offer. I think it was well oversubscribed according to the articles I read. I think there's a debt funding that follows that. And then their strategy is to obviously work on catching up in the market, investing pretty heavily, both in 4G capacity as well as a 5G build out.And what we provide is some of the optical and IP infrastructure as well as we're a provider on the voice side, on the Cloud & Edge business as well. So we're glad to see that really start to move in the right direction and hope that business grows pretty substantially in the second half of the year.

[Dave Kang, analyst]

And my last question is the Ciena sounded very cautious about the optical demand, optical market right now, even European market, but I didn't really get that from you guys. Is there like a market share shift going on? Why are you a little bit more optimistic than Ciena?

[Bruce McClelland, executive]

Yes, I think it depends on the segments, the part of the market where we're focused. Clearly, Ciena has a large business with the large carriers, strong business with the ICPs, where we're doing well is critical infrastructure, defense segments and some of the carriers. So the diversification that we've got has helped us here. Having both an optical portfolio and an IP routing portfolio really helps us. And so the result was, yet again, another quarter of growth, seven quarters in a row now, where we've had year-over-year growth in that segment. I think, it was 9% in the first quarter.

[Operator]

Next question is coming from Trevor Walsh from JMP Securities.

[Trevor Walsh, analyst]

Bruce, you mentioned last quarter about the larger Federal deal that had slipped into 1Q. Just more for confirmation on that, did the bulk of the revenue expected from that deal then kind of fall in the quarter, or might there be more kind of that further ramps up, kind of, next quarter throughout the year? And then I've got a follow-up, just kind of a broader kind of Federal spending atmosphere.

[Bruce McClelland, executive]

Trevor, good question. So as it turned out, that deal that has been awarded the revenue is actually still coming. So we expect actually more of it here this quarter and throughout the year. In the first quarter, we actually closed another deal, another extension deal with another agency. So you can get the idea, there's a lot of these kind of going in parallel. And as I've mentioned a few times, trying to predict the timing on them tends to be a little bit of a challenge. But it's great to see that we've got, I'll say, multiple irons in the fire, right? All these agencies need to do a modernization program not unlike the program we talked about with Verizon, where we're replacing legacy TDM infrastructure with modern cloud-based technology. And so in the first quarter, we had another couple of really substantial deals close and go to revenue. And the one I talked about last quarter is still coming forward, which is great.

[Trevor Walsh, analyst]

Great. That's super helpful and actually good segue to where I was going to kind of follow-up. Just we hear kind of different takes from companies that we cover that are doing business within the Federal kind of sphere around just the government funding via continuing resolution, et cetera, and some of the challenges there with the current Congress. Just curious to see what your take is and whether or not that is or isn't kind of affecting some of the timing on some of these things, and how you maybe see that progressing through the year? Obviously, not going to have you pontificate necessary along the election outcome, but just how you see that overall Federal business kind of flowing and kind of maybe some of the trends that you're seeing specific to Ribbon?

[Bruce McClelland, executive]

Yes, we definitely see it as a distraction. Even if funding is allocated and available on a particular program that we're working on, which generally speaking, is the case, either the CR process or the distraction around the shutdown threats back a few quarters ago, just tends to be a distraction for the people you're engaged with. They can't help but be distracted by it, particularly if there's a looming shutdown, they're planning around how they manage through that, et cetera.Again, the good news is we haven't seen any programs be unfunded or canceled or delayed. It's just does it get over the finish line one quarter versus the next one is really what we see. So, so far it seems to be manageable. You know, I did emphasize a little bit, and in fact, there's a new slide in our deck that's posted on the website just how significant the Federal and the government space has become for the company.In addition to the work we're doing here in the U.S. around voice modernization, we have a really important business internationally with a number of government agencies, both on the kind of the military side, the defense side, as well as on the civilian side. We're building out really secure -- highly secure information service networks is really important. And I think we're really differentiated there. If you get into the details on the products in the way that we encrypt traffic, the way that we protect message flows, et cetera, is pretty unique. And so that whole segment is really growing for us and was almost 10% of sales last year. So it's another important segment in diversifying the company.

[Trevor Walsh, analyst]

Great. Terrific. Maybe just one last one for me and then I'll get back in the queue. You had mentioned in your prepared remarks around just some of the differentiating factors around the security and kind of cyber aspects of the products. I'm just wondering, is it a function of kind of competitive products not really having anything to kind of help customers on that front? Or is it more just not -- just something that's not up on par with what you guys are currently doing? Just could you maybe just double click a little bit in terms of how you see that differentiation actually playing out on the security front?

[Bruce McClelland, executive]

Yes. So I think it comes from kind of the close engagement with a number of these agencies where we're dialoguing with them on what are their requirements, what are their future needs, and then building some of that into the product. So it starts out with somewhat of a custom capability, and then we make it more general that we can bring it to market to other similar agencies. And it actually helps out the rest of our critical infrastructure business if we're selling to an energy company or an energy distribution company, like American Electric Power, AEP, we talked about last quarter, the capabilities that we've built in for a defense application end up differentiating us in that space as well. So it's a bit of a long sales cycle, but once you're in dialoguing, understanding the future requirements, it really makes the whole portfolio better.

[Operator]

Next question is coming from Tim Savageaux from Northland Capital Markets.

[Timothy Savageaux, analyst]

Congrats on the results and the outlook, especially on the bottom line execution there. And you mentioned AEP, Bruce, and that was really the focus of my first question. That was one of a couple of deals, seemingly significant opportunities that you guys talked about last year along with AT&T. And I guess I wanted to ask about contributions from those opportunities in the first half, I guess, maybe Q1 or Q2, or what your expectations are for the year, and then maybe some broader commentary on your Tier 1 pipeline in IP Optical? And I'll follow-up from there.

[Bruce McClelland, executive]

Tim, if I just kind of take those one in time here. So, on AEP, the press release we did with them back early first quarter was at the culmination of signing a contract with them and becoming one of their suppliers in the network. We're now fully engaged with them on that program and have not deployed anything yet, but in process, if you will. So that's mostly a second half year program for us from an actual revenue perspective. So early days still, but great to have that partnership start to develop. And again, very similar to the types of deployments we have in Europe already today, with a number of energy distribution customers, like Axpo as an example, that's in the Swiss region.The AT&T engagement continues to progress nicely where we've been able to leverage both the voice core as well as our IP routing platforms into a combined solution that helps them modernize their TDM network. Somewhat similar to the Verizon announcement today, but a little different deployment strategy there. Again, that program just kind of continues to progress quarter by quarter throughout this year and hopefully scale into future years here.And maybe, Tim, the other questions around Tier 1 opportunities, again, as we've seen, the sales cycle is long on these, but particularly, as I mentioned, with the new platform we just introduced, that really moves us into the leading edge around optical transport. We're seeing good engagement there, activity both from an RFP, RFI process as well as proof of concept trials in the lab, in network, et cetera. So I'm hopeful we'll progress on some more of those types of announcements as the year goes on here.

[Timothy Savageaux, analyst]

Great. And then switching over to the Cloud & Edge side, I think, last quarter, you're talking about some different trends across the Tier 1 and kind of enterprise Federal part of the business, sort of leading to kind of a flattish outlook for the year, seems to be a change here in terms of looking for some growth in Cloud & Edge, maybe as a result of the Verizon deal, maybe some other factors. But can you confirm that your outlook is a little bit stronger here and talk about what's driving that for Cloud & Edge?

[Bruce McClelland, executive]

Yes. So the answer to that is definitely yes. As we put full year guidance together back in the early February timeframe, we had visibility on a number of these programs. We obviously had the discussion with Verizon in process at that point, and we're hopeful that, that would come to fruition. And you know as we sit here today, clearly being able to announce that today is a big deal for us and really puts a solid foundation under that business, not only in the second half of this year, but the next several years. So that significantly improves our confidence in that view, not only are we expecting growth in enterprise and Federal in Cloud & Edge, I think we definitely have the opportunity to grow now in service provider, which is a different -- kind of a different message. So it definitely gives us a lot more confidence in the outlook and we'll see where we're at mid-year.

Thank you. We reached the end of our question-and-answer session. I'd like to turn the floor back over to Bruce for any further or closing comments.

[Bruce McClelland, executive]

Okay. Great. Well, yes, thanks for that and thanks again for everyone being on the call here early this morning and in the interest in Ribbon Communications. We really look forward to speaking with many of you in the upcoming investor conferences. We have quite a slate coming up here in the second quarter and keeping you updated on our progress. So thanks very much and have a good week.

[Operator]

Thank you. That does conclude today's teleconference. You may disconnect your line at this time, and have a wonderful day. We thank you for your participation today.
