Hi, everyone. Thanks for joining us today. Our next presentation, presenting company is Ooma, which is traded on the New York Stock Exchange under the ticker symbol OOMA. Ooma creates powerful, connected experiences for businesses, consumers, and service providers, delivered through smart, cloud-based communications, platforms, and services. Here to tell you more about the company is Ooma's President, CEO, and Chairman, Eric Stang, and CFO, Shig Hamamatsu.
Thank you. Hi, everyone. Appreciate you joining us today. Let me first say, safe harbor statement, we're gonna make some forward-looking statements, and you can read the rest of this in that regard. So Ooma, providing, we believe, leading communications services from the cloud, and we try to use our technology to really create elegant, simple solutions, just saw a friend in the back there, so that they can be accessible to everyone. And in that regard, small businesses are a key focus for us as a company, as well as residential consumers. But to just give you a little scaling on the company itself, we have a January 31 year-end, so we're now in our fiscal year 2025. Last quarter, we did about $64 million, so we're running a little bit over $250 million a year run rate.
Along with that, we generated 9% EBITDA and $7 million in cash flow from operations. So we're a healthy, growing company, very little debt. We primarily earn revenue through our SaaS platform. About 93% of our revenue is recurring revenue. We have about 1.25 million core users. Core users are our residential and business UCaaS users and AirDial users, which I'll get into, but core users does exclude users on our wholesale platform and users who use our mobile app, Talkatone. So about 1,100 and some employees based in Sunnyvale, California, offices in Florida, Vancouver. In total, we're in a little bit over 30 countries today, though.
We have one very large customer, IWG Regus, the place you can go rent space for businesses, has used us, is using us through many of their locations. On the UCaaS side, we have kind of three areas to the business. The middle one is our primary focus today. That's our small business solution we call Ooma Office. We like to say it helps a small business sound like a big business at a small business price. We've put together a turnkey solution curated for the needs of a small business so that they can get up and running without the need of an IT professional and also save money, most likely, doing so. I'll be talking more about this as I go along, but I can tell you it's a very full-featured solution.
You'll get a PBX in the cloud with extension dialing, mobile app, desktop app to use your computer if you wish, call recording, video meetings, messaging, a whole host, eFax, a whole host of features on the platform, which really help a small business, kind of put the whole package together for communications. But we started out as a company serving residential customers. That's on the left here, the Ooma Telo, and that's still a very strong business for us today. A little bit less than $100 million of our $250 million a year in revenue comes from residential.
That business has been essentially flat for us the last several years, although we did announce last week in our earnings call that we have a new resale partner that has signed up with us that is going to be using our Ooma Telo to replace copper lines they now have in place with their customers. This is a great, sizable opportunity for us with a very large ILEC, local exchange carrier, where we think that will start to drive growth on the residential side as well. Ooma Enterprise, this is a smaller part of our business today. We don't talk too much about it. Here, we tend to focus on specific segments or verticals where we can bring a unique solution. The primary one for us today is hotels, hospitality.
We have hundreds of hotels on our platform today, and we're adding 50-plus hotels a quarter as we grow, and we're really excited about the potential here because we think we put together a very unique solution that's differentiated from the rest of the market. This kind of makes up our UCaaS go-to-market, with most of our spending from a sales marketing perspective on the small and medium business, Ooma Office in the middle. But we have two new areas, which I'll get to in a minute because I forgot I had this slide here. We're also very excited that in third-party surveys of users, we have been ranked number one for both our small business solution and our residential solution. PC Magazine does a user survey.
You can see that we have come out on top, which we're very proud of, and Consumer Reports has ranked us the number one residential phone service in America for, gosh, many years now. And so, and we feel we've built really solid solutions, which is kind of the foundation of the company. So these are the two new areas I wanted to talk about, which are also growth opportunities for us today. They are smaller than what I've already talked about, but, growing more quickly, as you'd expect. The first is our product on the left. We call it AirDial, and, it's there to be used to replace, copper lines that are going to equipment at businesses that, and for equipment that isn't easily served by, say, fiber or a standard internet connection.
There are millions of copper lines in the U.S. In fact, we've seen estimates of 10 million or more copper lines that are going to be sunsetted or go away over the next several years. In the meantime, they're going up in price, that's for sure, and we can drop an AirDial solution in place to replace that copper line, serve the equipment like the copper line was still there, and generate a great recurring revenue stream for us. I'll talk more about this in a minute, but it's kind of a new market opportunity that's just developing today, and is exciting. I mean, folks like AT&T have given estimates that they're gonna sunset half their copper lines or more within just a couple of years. So there's real momentum gaining around replacing copper lines.
And then on the right, our core platform, which we use in our solutions, is also available standalone for other companies that want to wholesale it and then build their own solutions to sell on top of it. And that platform we call 2600Hz. This is actually an acquisition we made last fall, but it's something we've used in our business for many years. And this gives us an entrée into many other providers of UCaaS and other types of services with a wholesale platform that they can build off of. And I'm gonna talk more about that in a minute, too.
So, but, you know, worldwide, we think there's a vast market opportunity here, of carriers and others that are using, others' platforms, which they'll need to move off of and be looking for a new platform to use. So kind of an extension of what we do in a different go-to-market approach. So saying a little bit more about AirDial, this is the kind of equipment that we would serve with it: an elevator phone, an alarm panel, a gate phone, a door entry phone. There's a lot of this type of equipment across the United States. You know, imagine a retailer with three thousand stores around the country, and they've got some of this stuff in every store. They need an AirDial in every store to power that equipment.
Those are the kind of customers we see out there, and we've been winning. This equipment isn't easily converted to work on a regular internet-type IP connection, so it becomes a very cost-effective solution to switch to AirDial. Either the copper line, you're being forced to because the copper line's being turned off, or you're also just doing it to save money. This is an important growth area for us. I can tell you, too, that same local exchange carrier that has copper in the ground that I talked about for residential earlier is also going to be rolling out AirDial for us, and this will become a major new opportunity for growth for us with AirDial. We have about 15 resellers of AirDial today.
Those include T-Mobile, US Cellular, some other companies we've announced, and now this new local exchange carrier who has the copper in the ground and is gonna be moving towards AirDial as their next solution is an exciting development for us. Our 2600Hz platform, to say a little bit more about it, we're very proud of the fact that it's been built in a very modern, designed way, which is to say it's API-based. There's roughly 300 APIs that make up how you use the platform. That means it's a very flexible and customizable platform, and that's where it really shines, I think, in the industry. We announced a quarter ago that a new customer for the...
had signed for us with the 2600Hz. They're going to use the 2600Hz platform to replace what they already have in market today. It's really exciting for us because this customer should become one of our very largest customers as a company, and they're gonna be rolling out this fall. We expect that they'll convert most or all of their users over to the new platform they're going to have in market based on 2600Hz, you know, through next year. They love this platform because they could build something unique to what they wanna do. Also, their prior platform that they're moving away from, they built off of a CPaaS solution, a CPaaS provider, if you know what I mean by that.
By moving to 2600Hz , they can host the platform themselves, get more control, probably a lower cost structure, and it just gives them the flexibility to take the next step. So it was a very big win for us, and we're excited about it, considering how big a customer we expect them to be. We've won some other customers on our 2600Hz platform already, and but this is really a developing market as more and more carriers and others try to think through what they're gonna do next from a platform standpoint. I've talked a lot about our platform. I won't say much about this slide, but we think we've got some unique capabilities. It's all Ooma in-house. We're not leveraging some third-party application.
As you can see, we're able to use it both to drive advanced solutions, but also lower costs for our customers. Speaking about cost, we estimate that our cost to provide service is about half that of what's kind of average in our industry. That's because we've designed everything kind of end-to-end with a model in mind that can drive a lower cost structure. Our ARPU is running on our core users about $15 a month, and you can see that we're driving a 72% margin off of that. You can look at some of our competitors and do these kind of calculations and see that we've gotten our cost structures to a very low level competitively, and we think that's a real competitive advantage as we go forward.
Small businesses, in particular, want and need a whole range of services, but they're very value-conscious, and we need to offer them, be able to offer them probably at a savings to what they were already using. We're able to do that by having driven what we feel is a very competitive cost structure. We look at the market, and this is North America, although we are in thirty-some countries, but we focus mainly on North America, as most of our sales come from. There's a large number of business lines, and you can see how some have converted and some, and most, have yet to convert.
We estimate there's about 6.5 million small businesses in North America of 1 to 20 employees, and less than half of them have converted to our types of cloud solutions. So, there's just a massive market opportunity to go after. At the small business level, you know, there's also a lot of new business formation and just a lot of interest in our kinds of solutions because it can make the business stronger. With small business, we offer premium tiers of service now. You can get integrations into your CRM solution, depending on what you have.
You can also use other capabilities that can make your business stronger, help you engage with your customers better, even have information provided to you when someone calls you that gets pulled out of your contacts or right off the internet. These are some of the ways in which we help to strengthen our small businesses. So it's obviously a massive market. It's growing 7%, as you can see here, according... you know, overall, we are growing faster, and Shig's gonna talk about that in a minute. So I've kind of talked a little bit about our go-to-market, but on the UCaaS side, it's primarily through direct sales and some reseller partners.
When we move over to our AirDial solution for POTS replacement, we have direct and partner sales, but we also have a number of resale partners that we're working with, including this latest one that I spoke about. And we do a lot of internet-based advertising and radio advertising and other ways that we try to reach out to customers to let them know about our solutions. Geographically, we are pretty widespread now, but our primary focus is still North America, just out of where we direct our resources for growth. So with that, let me just finish my part by saying we see a lot of small business out there with underserved needs.
Large businesses like hotels that have custom requirements we can serve uniquely, resellers that want to offer their own brand solutions with our 2600Hz platform or reselling some of our other product solutions, and you know, we're also growing adjacently in which, and geographically as we bring more and more features into our products over time. Shig? It's all yours.
Thank you. Good afternoon. I'm gonna quickly go over our financial profile. We just reported a quarter where we reported the $64.1 million quarterly revenue in Q2, and you can see on the far right, the breakdown of it, and as Eric mentioned earlier, on an annual basis, right now, we're running about $255 million. 93% of that is recurring revenue, and this is a core users profile to the right. In other words, Eric mentioned earlier that we have 1.25 million core users today, and the trend we are seeing is that we got an increasing mix of business customers. We just hit the 500,000 user count for business users, and they're generating 60% of recurring revenue.
The importance of that is that we have a higher ARPU for business customers compared to residential users. And what that also means that the, we're gonna improve the margin over time as we continue to increase the mix of business users. You might notice that the residential customer numbers are declining slowly, but with this ILEC win that we announced coming out Q2, with a residential opportunity, we believe that we have a significant opportunity to actually turn that around, particularly starting next year. Oh, excuse me, I meant backwards here. So here's the annual recurring revenue to the right. So we have $233 million and growing, and that was 8% growth year-over-year.
And with the business, revenue, customer revenue growth and also now the ILEC opportunity for residential, we believe we can continue to grow that even further at a nice pace in the future. ARPU is $15.07. That's a mix of business customers and the residential customers, and as you can see, we have an increase in that as well every year, every quarter. And we believe that we, we are the, one of the very few, if not the only one, in the UCaaS space to actually grow in that ARPU over time. So gross margin, so to the left is the historical, non-GAAP gross margin. Recurring revenue is 72%, overall, 62%. You might notice that there's 72% last year and this year so far, but that's part of it is we acquired companies we're integrating.
And so over time, as we continue to execute on synergies on the acquired businesses, and also to the extent, as I said earlier, we increase the mix of business customers with higher ARPU, we believe we can get to mid- to high-70s on the recurring margin in the future. This is a nice chart. We just reported the. So bar chart represents trailing twelve months adjusted EBITDA number in terms of dollars, and green line graph shows the trailing twelve months free cash flow. As you can see, we have steadily increased trailing twelve months adjusted EBITDA. We just reported the record $5.6 million adjusted EBITDA for Q2. That's a quarter record, 9% adjusted EBITDA margin.
We also generated $18 million of operating cash flow, trailing twelve months, and $12 million of free cash flow. You can see the accelerating free cash generation in the green line chart. We've got a pretty simple clean balance sheet. We carry about $17 million in the most recent quarter cash, a very low debt. Actually, we incurred debt only because we bought 2600Hz about nine months ago. We are paying that down very quickly. So low debt, we generate cash. Cash from operation was also a record in Q2, $7 million, and we have bought back also a couple of million dollars of our own stock in the quarter.
And we continue to be very opportunistic about buying back our stock, going forward as well as we generate more cash. Lastly, I wanna go over this mid to long-term model. So, middle of the page, you see, Q2, FY 2025, we just reported. And so again, 9% adjusted EBITDA, that was a record for the company. As we move towards a short-term, near-term, 1 to 2 years, we believe we have a pretty good visibility to get into the double-digit adjusted EBITDA range. And main driver with that is we have incurred 19% revenue for R&D so far to date, and a lot of the heavy investments that will drive the future revenue growth, so that will include the Ooma Office continued growth. We also have AirDial growth.
We also have residential growth coming up and other areas. All those heavy investments to drive that future growth is mostly behind us. So we believe that we can try to show some more, a lot more leverage in the R&D expense line to get it down to closer to mid-teens of revenue. And again, as I mentioned earlier, we think there's a room to drive the subscription margin higher as well. So those couple areas are major drivers of both the near term and the long-term adjusted margin expansion. Long-term column, we see that as four- to five-year timeframe, and we think we have a chance to double revenue from $250 million today, roughly, to $100 million, to get to that 20% plus margin. So that's $100 million or more of EBITDA dollars.
How do we do that? So we're gonna grow Ooma Office solution. We think that's a lot of runway left to grow the $100 million out of Ooma Office Solutions. We believe the AirDial alone can drive a $100 million of growth from where we are today to the next four, five years. We think the 300,000 lines installed on AirDial can drive a $100 million of recurring revenue out of AirDial. And by the way, that's 300,000 out of 10 million lines we think there are in the United States. So that's 3% market share target to get to that level. And lastly, the remaining $50 million, we can generate that growth from 2600Hz wholesale solution, as well as the residential solution.
So that's how we go from where we are today to four to five years double revenue to get to the 20% plus EBITDA margin. So that's the financial profile for us. Thank you.
Any questions? If anyone has questions... No questions?
Can you just explain on the opportunity for the new highlight you recently announced?
Yeah. So we announced that a top ten-sized incumbent local exchange carrier, someone with their own copper plant in the ground, they wanna sunset their copper, and they chose Ooma to do that. On the residential side, they've got hundreds of thousands of residential copper line users. For phone service, they're going to switch them out over time to an Ooma Telo for residential, which is exciting. I mean, we have seven hundred and fifty thousand residential users today, so, you know, talking to one customer with hundreds of thousands of users can make a sizable impact.
And then on the business side, they have hundreds of thousands of lines in place today with businesses, smaller-sized businesses, and they're going to use AirDial for any applications where there's hard-to-serve equipment, and they need connectivity to look like a, like a copper line. So again, a very big upside opportunity for us towards getting to that three hundred thousand lines that we're trying to drive overall for AirDial. It was an exciting win for us. The last two quarters, we've had exciting win each quarter, with the you know one quarter prior, the large customer on the 2600Hz side. So, and as we look at the industry, we think we can land more resale partners, as we go forward.
Our goal is to add one or two reseller partners for AirDial or Ooma residential each quarter. Yes, in the back.
Can you talk to competitors or competitive products?
Sure. It varies by each of the three or four segments I've talked about. In the small business UCaaS, it's pretty much cable or AT&T line or something like that. Most of our customers are moving to the cloud for the first time and getting the experience of all these additional, you know, capabilities they haven't had before. When you move to AirDial, there's a couple of large aggregators. These are companies that buy and resell solutions primarily and try to be your one-stop telecom provider to large companies. The two that we see most active and with an alternative to AirDial are Granite and MetTel, if you've come across them. Now, we particularly run into them where it's a customer, where they already have that customer for other reasons.
And then, on the 2600Hz platform front, I didn't go into this so much, but the BroadSoft and Metaswitch platforms that are out there today, aren't, are. Well, in the case of Metaswitch, actually going away over time. And, there's ourselves, and generally, there's Crexendo with NetSapiens. And after that, there aren't many platforms to turn to. So we feel, we're in a pretty unique position to be, the next generation platform for a lot of these partners. Eric? Yeah.
Yeah, the retention, just wondering, you know, with the kind of rumbling in the macroeconomy, are you seeing any signs of maybe retention issues with your SMB customer base?
Is the short answer. Our SMB customer base has been, if you looked at retention or stability, it's been very stable, for years and years. And I think our net dollar retention rate, which, you know, is a calculation that also includes increases at existing customers, runs around 99% or 100%, as a retention rate. But generally, our churn, both for residential and small business, on average, runs around 1% a month, and it's stable.
I think we're just about at time here. Really appreciate you guys presenting today, and thank you all for attending.
Thanks, everybody. Appreciate it.
