Q3-2024 Analysis
Ooma Inc
Ooma reported a strong financial performance in Q3 with total revenue of $59.9 million, a non-GAAP net income of $4 million, and EBITDA of $5 million. The company achieved a 14% year-over-year increase in business subscription and services revenue organically and secured a 17% growth in EBITDA compared to Q3 of the previous year. During the quarter, Ooma also made a significant move by acquiring 2600Hz, a move aimed to unlock operational benefits and enhance strategic capabilities.
Ooma pursued strategic expansions to increase its revenue from business customers. Notably, Ooma Office added premium features and new integrations, such as with Clio. The company also announced its service launch for International Workplace Group (IWG) in Asia and Africa, and now serves IWG in 30 countries across five regions. Additionally, Ooma continued to focus on the hospitality vertical and the AirDial strategy, securing new resellers and two of its largest AirDial customers to date.
Following the acquisition of 2600Hz, Ooma has been working on integrating teams, rationalizing spending, and establishing a combined strategy. This strategy includes leveraging Ooma's technology and scale to strengthen 2600Hz in the market, along with rolling out new services to 2600Hz customers. The response from 2600Hz's customer base has been positive, and there is excitement about the potential synergies and new opportunities with Ooma.
Ooma provided its financial outlook, expecting total Q4 revenue to be between $61.2 million and $61.8 million, including a full quarter's impact from 2600Hz. Q4 net income is expected to range from $3.1 million to $3.4 million, with non-GAAP diluted EPS between $0.12 and $0.13. For fiscal year 2024, the company anticipates a total revenue of $236.3 million to $236.9 million, with a non-GAAP net income between $14.9 million to $15.2 million, and adjusted EBITDA of $19.4 million to $19.7 million. The non-GAAP diluted EPS for fiscal 2024 is expected to range between $0.57 to $0.58.

Thank you, Matt. Hi, everyone. Welcome to Ooma's Third Quarter Fiscal Year 2024 Earnings Call. Thanks for joining us. I can report that Q3 was another strong quarter for Ooma. We performed well financially and made a major advance by acquiring 2600Hz during the quarter. We look forward to reviewing our progress with you. Our Q3 results include $59.9 million in revenue, $4 million of non-GAAP net income and $5 million of EBITDA. Organically, for Q3, which is to say, excluding the impact of 2600Hz, we increased our business subscription and services revenue 14% year-over-year. We held our OpEx spending nearly flat to 1 year ago, and we grew our EBITDA by 17% versus Q3 last year. Our annual exit recurring revenue, including 2600Hz, is now $225 million. We feel these results demonstrate good progress for the company and strong performance for the quarter.During Q3, we continued to pursue the strategies we have outlined throughout this year to expand Ooma's revenues from business customers. Ooma Office, our award-winning solution for small to medium-sized businesses added premium features and new integrations. One of our most exciting new integrations is with Clio, the #1 software used in the legal industry. Users of Clio can now integrate their Ooma calling and communications with their Clio experience. This integration is available as part of Ooma's Pro Plus service tier and contributes to our long-term strategy of increasing our premium office users and raising our average revenue per user.I'm pleased to report that in Q3 we once again sequentially increased our ARPU from business customers. I'm also pleased to report that 56% of our new Office customers were premium users and that premium users now make up 28% of our total office customer base.It was exciting in Q3 to announce finally the name of our largest customer, International Workplace Group, or IWG, which is also known by the name Regus. We made the announcement in conjunction with the launch of our services for IWG in Asia. In Q3, we rolled out our platform for the Africa region and started serving IWG in South Africa.In total, we now serve IWG in 30 countries across 5 different regions, and we are working with them to expand further. We anticipate slower international expansion in Q4, given the holidays, followed by a pickup in Q1 as we roll out to new countries throughout the first half of next year.Outside of North America, we also expanded with Ooma Enterprise, which began serving a new customer with locations spread across Australia, Netherlands, Spain and the U.K. in addition, of course, to here in the U.S.A. In our targeted hospitality vertical, we once again landed over 50 new hospitality locations, the largest of which being a property with 474 rooms and another being our second airport hotel. In general, we believe our strategy in Enterprise to focus on select verticals is giving us advantages in the market.In Q3, we continued to pursue our AirDial strategy aggressively. In particular, we hired additional sales personnel and signed a total of 4 new AirDial resellers, one of which touchtone communications we announced in our press release. These resellers join a number of others we are already partnered with for AirDial, including T-Mobile and more recently, U.S. Cellular. We also announced that Viking Electronics, who is a manufacturer of more than 500 security and communications products, including emergency phones, entry systems, elevator phones and campus safety phones began recommending AirDial to its customers and distributors after performing their own extensive testing of AirDial.As we've mentioned, we believe AirDial offers the best solution in the marketplace for replacing increasingly expensive and soon to be decommissioned copper lines that are connected to elevators, fire alarm panels, older PBX equipment and more. We are thrilled by the validation we are seeing by the many resellers we have signed up for AirDial.We are also thrilled to have announced in Q3 that Elevator World magazine, the leading media voice in the vertical transportation industry, selected Ooma for the 2023 Ellies Awards in the category of Best Communication System Supplier, honoring the Ooma AirDial solution for POTS replacement.We are not standing still either in our continued improvement of AirDial. Just recently, we announced that AirDial now incorporates Ooma's patented multipath technology. Multipath creates a continuous dual connection between AirDial and the public switch to telephone network by transmitting data packets simultaneously through 2 separate data links.Unlike other approaches where calls are dropped on failover, where there can be delays before failover occurs and where other issues can occur related to the quality of individual transport links, Ooma's multipath technology provides seamless backup for customers who enable 2 internet connections to their AirDial device. Multipath provides one more example of how Ooma stands out by providing the full end-to-end AirDial solution encompassing both cloud and customer premise equipment.While not announced, we also made additional improvements in Q3 to AirDial's Remote Device Manager, or RDM, as we call it. RDM gives our AirDial customers the ability to provision, monitor, manage and control all of their AirDial devices from one portal. We view RDM as another key differentiator for AirDial.I'm pleased to report that in Q3, we landed what we expect will become our 2 largest AirDial customers today. One of these customers is a large retailer with many individual brands. We've already started rolling out AirDial to one brand of stores owned by this customer, where we are displacing another POTS replacement solution. We expect this rollout is just Phase 1 with this customer.The other customer is a provider in the elevator industry with access to a very large number of opportunities. I'm pleased to report our backlog of potential sales opportunities grew again in Q3, and we have many large opportunities that we are pursuing.I'd like to turn now to 2600Hz, which is the new business we acquired back in October. As a reminder, 2600Hz provides open source, core calling functionality named KAZOO that is in use today by many telecom providers. Since initially launching KAZOO over 1 decade ago, 2600Hz has also expanded to provide its own non-open source suite of pre-built UCaaS, CPaaS and call center applications. Telecom providers have the choice of relying solely on open source KAZOO and building applications themselves or contracting with 2600Hz for a more complete solution.2600Hz today provides hosted cloud, private cloud and customer hosted solutions to approximately 130 paying customers who serve hundreds of thousands of end users. The company runs data centers in 8 locations spread across North America, Europe and Oceania, maintains a workforce of about 100 employees and contractors and has revenues of approximately $7 million annually.3 main reasons drove our decision to acquire 2600Hz. We made this acquisition to capitalize on the opportunity we see in the wholesale marketplace to unlock significant operational benefits between Ooma and 2600Hz and to enhance Ooma's strategic position and ability to serve the fundamental needs of large carriers and other partners.It's now been about 6 weeks since 2600Hz became part of Ooma. In that time, we have blended our 2 teams together, rationalized spending in certain areas and established our new combined strategy. Central to our strategy is to strengthen 2600Hz in the marketplace by leveraging Ooma's application technology, scale and low-cost position and by launching new services. We are now actively working internally to provide 2600Hz customers, telecom services delivered in a CPaaS business model. We're also working to leverage some of Ooma's key user applications for the benefit of 2600Hz customers.2600Hz's customer base has responded with positive feedback on our acquisition. They are excited about our strategic direction and the intellectual property and resources we bring as a larger scale and more mature organization. Similarly, we already have active conversations underway with a number of possible new customers. These conversations will take time as possible customers evaluate KAZOO and get to know us, but we are optimistic about their potential. Overall, I believe our integration with 2600Hz is going well, and we are on track as promised, to make the acquisition adjusted EBITDA accretive to Ooma within 6 months.Finally, I'm thrilled to mention that the publication you see today recently named the KAZOO communications solution from 2600Hz as the Best White Label Solution at the prestigious UC Partner Awards 2023. KAZOO was chosen by a panel of 12 leading analysts in the cloud communications industry from a field of 4 finalists. Of course, we're not surprised since we know KAZOO's modern API-based architecture sets it apart in the industry.With that, I will now turn the call over to Shig, our CFO, to discuss our results and outlook in more detail and then return with some closing remarks.
Thank you, Eric, and good afternoon, everyone. Before I dive into our third quarter financial results, I'd like to quickly recap the financial aspects of the 2600Hz acquisition we completed on October 20, 2023, right before the end of the third quarter. We acquired 2600Hz for approximately $33 million in cash, and there are no other contingency payments for this acquisition. With regard to funding of cash purchase price, we used approximately $50 million of our cash from balance sheet and the remaining $80 million came from a new $30 million revolving line of credit from Citizens Bank.2600Hz is expected to add approximately $7 million in annual recurring revenue to Ooma. The acquisition of 2600Hz is expected to be accretive to our adjusted EBITDA within 6 months and make increasing contribution to our overall adjusted EBITDA as operational synergies are realized in subsequent periods.Now I'm going to review our third quarter financial results and then provide our outlook for the fourth quarter and full year fiscal 2024.We delivered another solid quarter with a total revenue of $59.9 million, which included $0.23 million of subscription and services revenue from 2600Hz for the last 12 days of the quarter. Excluding 2600Hz revenue contribution, Q3 revenue came in at $59.6 million at the high end of our guidance range of $59 million to $59.6 million. On a year-over-year basis, total revenue grew 6% in the third quarter, driven by the growth of Ooma business, which accounted for 58% of total subscription and services revenue as compared to 55% in the prior year quarter.Q3 product and other revenue came in at $4 million as compared to $4.9 million in the prior year. The prior year Q3 product revenue included certain [ accessory ] sales that did not recur this year.On the profitability front, the third quarter non-GAAP net income was $4 million. Excluding $0.3 million of net loss from 2600Hz, the third quarter non-GAAP net income was $4.3 million, exceeding our guidance range of $3.8 million to $4.1 million and represented 24% increase over $3.5 million in the prior year quarter.Now, some details on our Q3 revenue. Excluding the impact of 2600Hz, Ooma Business subscription and services revenue grew 14% year-over-year in Q3, driven by user growth. On the Residential side, subscription and services revenue were flat year-over-year. As a reminder, we had a onetime churn event during the first quarter of this fiscal year with a particular customer with an unusual application where we lost approximately 4,000 tele users, which continue to impact our year-over-year comparison in Q3.For the third quarter, total subscription and services revenue was $55.9 million or 93% of total revenue as compared to $51.7 million or 91% of total revenue in the prior year quarter.Now some details on our key customer metrics. Please note that the key metrics I'm about to discuss do not include any metrics related to 2600Hz users. Given the wholesale nature of 2600Hz's business, we do not intend to blend 2600Hz user metrics into our traditional core user metrics, which will continue to represent the key metrics related to Ooma Business and Residential users only. We ended the third quarter with 1,241,000 core users, up from 1,237,000 core users at the end of the second quarter. At the end of the third quarter, we had 475,000 business users or 38% of total core users, an increase of 8,000 from Q2.Our blended average monthly subscription and services revenue per core user, or ARPU, increased 3% year-over-year to $14.63, driven by an increase in mix of business users, including higher ARPU Office Pro and Pro Plus users. During the third quarter, we continued to see a healthy Office Pro and Pro Plus take rate with 56% of new Office users opting for these higher tier services, which was up from 50% in the prior year quarter. Overall, 28% of Ooma Office users have now subscribed to our Pro or Pro Plus tier.Our net dollar subscription retention rate for the quarter was 99% as compared to 99% in the second quarter. Our annual exit recurring revenue, which now consists of recurring revenue from Ooma core users and 2600Hz users, grew to $225 million and was up 10% year-over-year.Now some details on our gross margin. Our subscription and services gross margin for the third quarter was 72% as compared to 73% in the prior year. Q3 subscription and services gross margin this year was impacted by certain investments we made for our largest customer as we started the further expansion into Asia and Africa in the third quarter as well as investments in our customer support resources for ongoing AirDial [indiscernible].Products and other gross margin for the third quarter was negative 73% as compared to negative 35% for the same period last year. As mentioned on the previous calls, the decline in Q3 product gross margin this year versus last year was anticipated and primarily due to the following 2 factors: first, we saw a sell-through impact of certain higher cost components that we have procured in the last fiscal year to stay ahead of pandemic-driven supply chain issues; and second, the prior year Q3 product gross margin benefited from certain [ accessory ] sales that did not recur this year. We continue to expect product and other gross margin for the remainder of fiscal 2024 to be negatively impacted by onetime excess component costs running through the P&L and currently estimate product and other gross margin for the fourth quarter to be in the neighborhood of negative 70%. On an overall basis, total gross margin for Q3 was 62% as compared to 64% in the prior year quarter.And now some details on operating expenses. Total operating expenses for the third quarter were $33.4 million, up $0.6 million or 2% from the same period last year. Excluding the impact of 2600Hz, the total operating expenses increased $0.1 million or effectively flat from the same period of last year.Sales and marketing expenses for the third quarter were $16.8 million or 28% of total revenue and flat year-over-year. Excluding the impact of 2600Hz, sales and marketing expenses for the third quarter were $16.6 million or a decrease of $0.3 million from the same period last year as we control our spend into increased profitability.Research and development expenses were $11.3 million or 19% of total revenue, up 3% on a year-over-year basis from $11 million, driven by investments in new features for Ooma Office and Enterprise as well as AirDial. Excluding the impact of 2600Hz, R&D expenses for the third quarter were $11 million, flat compared to the same period last year. G&A expenses were $5.3 million or 9% of total revenue for the third quarter compared to $4.9 million for the prior year quarter. The year-over-year increase in G&A expenses was primarily due to an increase in personnel costs.Non-GAAP net income for the third quarter was $4 million or diluted earnings per share of $0.15. Excluding the impact of 2600Hz, non-GAAP net income for the third quarter was $4.3 million or diluted earnings per share of $0.16 as compared to $0.14 in the prior year quarter.Adjusted EBITDA for the quarter was $5 million or 8% of total revenue. Excluding the impact of 2600Hz, adjusted EBITDA for the quarter was $5.2 million or 9% of total revenue and represented a 17% increase over $4.5 million for the same period last year. We ended the quarter with total cash investments of $18.9 million. We generated cash from operations of $1.9 million as compared to $2.5 million in the same period last year.As mentioned earlier, we funded a cash purchase price of 2600Hz with a combination of cash from our balance sheet and an $18 million draw from a new $30 million revolving line of credit. The new credit facility has a 3-year term and the borrowing under it will bear interest rate based on [ SOFR ] plus 210 basis points or approximately 7.5% of all-in borrowing rate at the time of the drawdown in October. The additional details on the credit facility are available in our Form 8-K filed on October 23, 2023, as well as in our Form 10-Q to be filed later this week. On the headcount front, we ended a quarter with 1,192 employees and contractors, which included new team members from 2600Hz.Now I will provide guidance for the fourth quarter and full fiscal year 2024. Our guidance is on a non-GAAP basis and has been adjusted for expenses such as stock-based compensation, amortization of intangibles and certain non-recurring items. Additionally, the guidance reflects a full quarter impact of 2600Hz starting in the fourth quarter as well as interest expense for the outstanding balance under the new credit facility and the partial benefit of related restructuring activities took place earlier in the fourth quarter. We expect total revenue for the fourth quarter of fiscal 2024 to be in the range of $61.2 million to $61.8 million, which includes $3.8 million to $4.1 million of product revenue.We expect the fourth quarter net income to be in the range of $3.1 million to $3.4 million. As mentioned earlier, Q4 net income guidance includes a full quarter impact of interest expense related to the new credit facility, which is estimated to be approximately $0.4 million. Additionally, the guidance assumes interest expense will be sequentially lower by approximately $0.2 million, given that $15 million of cash from balance sheet was spent towards a cash purchase price of 2600Hz.Non-GAAP diluted EPS is expected to be between $0.12 and $0.13. We have assumed 26.7 million weighted average diluted shares outstanding for the fourth quarter. For full fiscal year 2024, we expect total revenue to be in the range of $236.3 million to $236.9 million.In terms of revenue mix for the year, we expect 93.5% of total revenue to come from subscription and services revenue and the remaining 6.5% from products and other revenue. We expect non-GAAP net income for fiscal '24 to be in the range of $14.9 million to $15.2 million.Fiscal 2024 net income guidance also reflects an increase in interest expense related to the new credit facility of approximately $0.4 million as well as a reduction in interest income of approximately $0.2 million for the reasons stated earlier.Based on this non-GAAP net income guidance range, we estimate our adjusted EBITDA for fiscal 2024 to be $19.4 million to $19.7 million or approximately 8% of revenue. We expect non-GAAP diluted EPS for fiscal '24 to be in the range of $0.57 to $0.58. We have assumed approximately 26.3 million weighted average diluted shares outstanding for fiscal 2024.In summary, we are pleased with our solid performance in the third quarter. The team has done a great job of growing business subscription revenue 14% year-over-year organically, while keeping operating expenses effectively flat in today's economic environment, which resulted in year-over-year organic non-GAAP net income and adjusted EBITDA growth of 24% and 17%, respectively.I'll now pass it back to Eric for some closing remarks. Eric?
Thanks, Shig. Q3 was a busy quarter for us. We worked to grow our business user base and to expand internationally. We also invested significantly to increase our AirDial sales team, number of resellers and pipeline of opportunities, and with those, our AirDial installed user base. On top of these, we also closed on our 2600Hz acquisition and took steps to integrate 2600Hz into Ooma and along with that, optimize our cost structure. I feel we're well along on our plans for 2600Hz and the acquisition is going smoothly. Our plans for Q4 entail continued focus on our multiple strategies for growth, in combination with sensible expense management and continued cash generation from operations.Thank you. We'll now take questions.
[Operator Instructions] Our first question comes from the line of Mike Latimore with Northland Capital Markets.
On the -- your largest customer, which is [ now ] Regus, how many users do you think that they will have by fiscal year-end now? And then I think you said you expect to launch new countries next year. I guess what's the kind of incremental opportunity next year?
Yes. So we're over 85,000 users with them now. And we did not have as much growth in Q3 as we might have because some of these new countries are taking a little bit more work on both sides to bring up and get going. And Q4 will be a little slower too just with -- it's a lot of work to do this and the teams need a little bit of a break. But we'll be up over 90,000 at the end of the fiscal year. And I've talked in the past that we could get to maybe 120,000 or so, and that's where we're working towards for the first half of next year. But each -- it's an extra effort every country we add and the countries are smaller now than the ones at the outset. So how fast we get there, I'm not exactly sure. But we're anticipating the first half of next year is still busy with [ adding ] users.
And then how much is the U.S. small business market? Any noticeable change versus last quarter in terms of just sales cycles, collections, just general activity in sort of small business UCaaS land?
Actually, no. Sales cycles are similar. No collections issues other than the normal ones we have. We're a little cautious for Q4 because, as we remember last year with the holidays and all, small businesses were busy or finishing up their years. And then, obviously, we kicked off in January with a good market opportunity. But we think the markets -- it was stronger during the COVID time when everyone was figuring out new solutions, but it's still robust. And most importantly, there's a big market that's yet to be brought up to a modern communication solution like Ooma provides. So we see lots of opportunity to go after.
And just last one on product gross margin. Once some of the anomalies come out of the mix here, what should that product gross margin normalize to?
Yes. It's -- probably we're talking about Q2 next year once we get through the consumption of the higher cost components, Mike. But I think a normalized range, I would say, 50% to 55% kind of [ range ]. We traditionally were there before we had this component. So that's what I would say.
Our next question comes from the line of Erik Suppiger with JMP Securities.
First off, just on the outlook for Q4. It does seem as though you're looking for relatively flat sequential growth on the subscription revenue on an organic basis. Is there any reason you're more conservative there?
So on an overall total revenue basis, one of the reason is we had about $400,000 of non-recurring product revenue in Q3 that we're not going to have in Q4. So that's [ why ] the total revenue seems flat quarter-over-quarter. And then there is one adjustment that -- on the business subscription side that in a sequential basis we're making that really just onetime in nature, and it's now fundamentally nothing different about the trend itself. So if you take out these 2 items, fundamentally, we see still the subscription revenue growing at a more normalized level, which is, I would say, several [ hundred thousand dollars ] quarter-over-quarter. So it's a little bit hard to see, obviously, with some of these pointers, but that's what we see.
And then you said Regus could reach, I think you said 120,000 end users. How many countries would you anticipate that, that will be?
70 or so. Over 50 for sure. We're already able to serve more countries than they're -- we're now in with them as we wait for conversions and rollout to happen. But I believe we'll be in a vast majority of the countries that are now in. They're in a total of about 100 countries, but I need to be a little conservative because I think we'll see how it runs out in the tail. Some of the countries are quite small.
And then how do you anticipate generating follow-on business with those countries? Is that kind of -- can you talk a little bit about the timing around that?
Well...
[ Follow on ] business with additional customers that is.
Sure. So obviously, the next 6 to 9 months is just rollout phase of -- as we've discussed here. They are a growing organization. So that's potential growth for us. And also, we're serving their -- the kinds of users of theirs that we're serving are the ones that have -- that are operating in their buildings. They have other users that do other things with them, that are a potential for us down the road as our more premium solutions that we could roll out with them as well. I don't want to get too much into where we see it evolving next, but we think we'll have more opportunities for growth after we get this rollout under our belt.
Our next question comes from the line of Josh Nichols with B. Riley.
I was wondering if you could elaborate a little bit -- I think you mentioned that in the quarter you landed 2 AirDial customers that you think ultimately are probably going to become the largest customers. I know AirDial has taken a little bit longer to ramp than originally anticipated. But could you provide a little bit more clarity on the type of market opportunity that those 2 customers represent? And do you have any visibility into what type of installed units these 2 customers alone could represent if we think about over the next 12 to 18 months?
Sure. Yes, we mentioned -- to clarify my words, we mentioned they could be the 2 -- our 2 largest customers to date. We do have other customers we are pursuing in our sales funnel that are even larger. But each one is thousands of users, and let me put it that way, not over 10,000, but thousands of users potential. The other thing we've seen is all through this year -- the first 3 quarters of this year, the number of opportunities in our sales funnel, particularly the number of potential users in our late-stage sales process has grown each quarter, and that also helps us get a better understanding of where we can go with this.We did make a big step in Q3. We were able to fill several sales positions for AirDial, which will allow us to go after the market more strongly. We have 10 different verticals that we're pursuing with AirDial. And if you look at the opportunities we have and even just what these couple of customers can represent, it continues to be a very positive opportunity for us. But obviously, as you said, we need to get -- we would like to move faster, and we're doing -- and we're investing to do that.
And then just 1 or 2 small things. Shig, did you mention, I think you said product revenue would be between $3.8 million and $4.1 million for the fourth quarter?
Yes, correct. Yes, that's correct.
So [indiscernible] [ kind of ] in line.
Yes.
And then last question. I know that there's like a big delta between the GAAP and the non-GAAP guidance for 4Q. I know that's not super surprising given the acquisition. I was just kind of curious what you were expecting for onetime costs? Just trying to think about how to manage or model the cash flow for 4Q?
Yes. So the fourth quarter, we're going to have a few onetime costs. So one item is our restructuring cost -- restructuring activities we undertook. There's a cost associated with it, it's in press release, Josh, with $0.5 million that we're incurring there in Q4. And we also have some additional acquisition-related costs. But we can get -- it's actually in the press release too, and happy to get you a little more detail there.
Our next question comes from the line of Brian Kinstlinger with Alliance Global Partners.
Congrats on the successes with AirDial. My one question is last quarter you talked about, there were challenges in the pace of installations. Some of it were people, some of it were the various places where installs might happen. What progress has the company made, especially within its control -- the piece of [indiscernible] control, if any, to help improve installation rates?
Yes. I feel we've got that well in hand, actually. We have a customer right now who wanted to roll out to quite a significant number of locations and do it all in 1 week, and we did it. And -- so when a customer is ready to move and if the customer knows what their needs are and where their needs are and has the access and all that planned out, we can move quickly with them. Not all our customers are like that. Some customers can take several months just to even stand up a proof of concept and test something for then a couple of months more. But sometimes you get customers who have a deadline and they want to move. So I feel like the pace of rollout is being driven more from what customers can accomplish than what -- than our team. We're ready to go.
I guess my second question for Shig would be, when the installations start ramping and they become a more meaningful piece of revenue, just remind us the puts and takes to product revenue and margin versus subscription and services?
Yes. So as the installation [indiscernible] -- So we're reporting the cost and revenue related to installation activity itself in a product, along with the product itself. And so we're going to start to see that product revenue increase as we ramp on the installation. And I think we talked about it earlier, but our intent is to not lose money on the installation activities, meaning that we pass on a cost to customer to achieve that. And so my take on that is, as we have more AirDial-related product installation revenue, product margins should improve as well over time. Obviously, that will precede the ramp on the subscription revenue related to AirDial because the installation needs to happen in front of it. And we're still seeing a pretty good trend on AirDial ARPU on the service side, and we think it's going to be accretive to our subscription margin today as we ramp on the subscription side as well.
[Operator Instructions] Our next question comes from the line of Matthew Harrigan with Benchmark.
Firstly, since you're not including 2600Hz in your KPIs, I mean, it's pretty evident we're going to be modeling that longer term. You talked about some of the growth opportunities there with some of the customized apps and certainly even better monetization of KAZOO. What's your ambition in terms of the long-term growth rate there, which presumably exceed that -- your core business? And then secondly, on your existing subscription business, you said that 28% are taking Pro or Pro Plus right now. I mean, you've got a good product incrementally at pretty low incremental cost. Why is it -- I know I've asked you this before, but how -- do you consider building more to marketing to upgrade the installed base? I don't know whether it's much more of a brotherly [ shove ] than it looks like on the surface to get people to upgrade. But presumably, you could be affording more utility for our customers and ramping [ user ] [ growth ] rate, while you do it at the same time?
Yes. Well, we do a bit of outreach to our existing customer base around Pro and Pro Plus. You got to keep in mind that when they came on board as users, they self-selected at the time with our solution. So they're pretty happy with what they've got, many of those users. In some cases, it's hard to reach out to them too, because marketing e-mails don't always get to flow through. But we do see customers as they expand, starting to tap into some of our new capabilities. And as I said, the new customers coming on board are coming on -- more than half of them are taking a premium tier.It might be -- part of it a little bit might be to just -- you really need to explain it to customers and our salespeople are able to do that with the new customers. It's a little bit hard to have those conversations at that level with our installed base. But it is something we work on and we can develop more resources too going forward. First question again...?
Would there be [indiscernible] you do -- sort of push free trial for like 1 month or 3 months just show [ them ] the capabilities? I assume the expenses wouldn't be that high to do it? Or is that let's just offer it in terms of the software upgrade?
No. We do different kinds of things, sometimes more or less of that nature. Yes, it's a good question. And what we tend to do today is just send e-mails with a little bit of information on some of the features that people could get. But free trials aren't a bad way to go either and keep that in mind.
I think, Matt, your first question was something on the line of, with respect to 2600Hz, what sort of growth rate that you could assume in relation to the core business, or something like that, right?
Yes.
Exactly, because it's pretty -- people are going to be modeling that separately since you're not including that in your core KPIs, as you stipulated.
Yes. We're a little reluctant to try to answer that question with too much detail because it's only been 6 or 7 weeks that we've been developing this opportunity now and [ owned ] it. But we do see real meaningful opportunities. There are users out there of the KAZOO platform from an open source perspective that could be converted over into paying users by offering them more than what they have today. There are significant opportunities for new customers to be brought on to the platform, some of whom would be moving off another platform that's out there, and others that just are going to sunset maybe something they've built internally and want to move to something more modern. I think we are close to getting our first customer to move off of another company's platform and on the KAZOO. But we'll have to wait and see if we close that in Q4.And then thirdly, the CPaaS services -- and we have a very specific effort in place today to bring Ooma's cost structure and scale in telecom services as a CPaaS offering to the installed base and then move from there. Predicting what that will be for next fiscal year is hard for us. I think that we'll learn a lot in the next 3 months in our sales efforts and then be able to give better guidance at the end of the next quarter.
Our next question comes from the line of Arjun Bhatia with William Blair.
If I could just go back to the user growth. I know it sounded like it was your largest customer region that was driving some of the headwinds there. But if we look to other customers, are you seeing similar kind of muted growth there in Q3 and Q4? Or is it largely related to Regus where we're seeing slower growth from the customer base -- from the user base rather?
Yes. Well, we're thinking for both Q3 and Q4. Particularly Q4 now, we're going to see, as you said, muted growth with our large customer. But beyond that, we want to be cautious because Q4 is an interesting quarter with the holidays involved and small businesses taking time off for being very busy with the holiday time. It's not always the best time for customer acquisition. We're being very sensible about that in our investment strategies. We are controlling our sales and marketing spend. We're happy with our customer acquisition costs, and we're improving the EBITDA commensurately. Our EBITDA is growing faster than our -- the growth of our other metrics. So I think we have a good plan for Q4. And -- but yes, we're being a little guarded just to wait and see how it turns out.I can give one more data point. I know you didn't ask about Residential. But we're pleased with our Residential business thus far into the quarter. We're through Black Friday and Cyber Monday and that Thanksgiving period when we want to drive some sales on the Residential front, and we were happy with what we achieved this year compared to 1 year ago. So that's one piece of positive news that we already have.
And then maybe going back to Regus. I know you're talking about expanding into other countries and the opportunity that could pose longer term. How should we think about what that process is like to go into other countries? How long does it typically take to open up a new geography? How many resources are required? What are the challenges? Maybe just help us understand that process a little bit better.
Sure. I'm going to repeat some of the things I may have said in previous calls, I apologize. But -- so it starts with putting our capabilities into the region. Because we're dealing with communications services, you have to be mindful of internet distances and delays that can affect the quality. So we have to have fully standalone instances of what we do in each region where we want to serve the countries there.As I said, we're in 5 regions today, and we can serve all the countries now pretty much in those regions, although we aren't yet. And then we have 2 more regions to stand up between now and the middle of next year. Once we have those 7 regions in place, we'll have very good coverage. And then it comes down to what you need to do to be in that particular country. There may be certain laws and regulations you have to conform to, certainly language and other adaptations to the platform, maybe calling patterns. You have to decide how you're going to deliver services from a carrier partner status. And then once you have that in place, plan a rollout strategy that involves converting away from something already in place, and there's a lot of work to do that.So we tend to roll out with our large customer kind of country by country or a couple of countries in the region at a time and then you move on to the next ones. And we went into Hong Kong in Q3. We went into South Africa in Q3. There are other countries in Asia that we're expanding in, in Q4. We'll be finishing up South Africa in Q4, and we'll just be rolling out from there.It's giving us an incredible footprint on a much bigger stage than we've operated on in North America, and I think that's a really valuable asset for Ooma as we look forward, not only for our UCaaS solutions, but also, frankly, for AirDial. And we're going through the thinking right now on what our priorities will be for next year to start to capitalize on this asset beyond North America.And AirDial will be a very strong contender for that because we think we have such a unique solution there and kind of a unique market opportunity at this time. So it's exciting for us to have this in place. We're well down the train on all of this, not to go on, but it's been years in the making to be where we are today. And we're just getting over, I think, the final hurdles.
And sorry, one more if I can just follow up. And the -- Is the subscription and services gross margin following this international build-out? Meaning once this is -- once you have the additional regions stood up by the middle of next year, should that be the trough in subscription gross margins? Or are there other factors that maybe I'm not considering there?
Yes. So certainly, we talked about this a little bit, but we're making some investments related to the expansion that Eric and I talked about -- we just talked about. So it's pulling down revenue a little bit upfront -- I mean the gross margin a little bit upfront on the subscription side. I think -- going into second half of next year, I think we started to see more scale efficiency there. Well, we expect [ our ] largest customer as well. And also, [ near term ] remember that 2600Hz gross margin on recurring revenue isn't quite at the level that corporate Ooma margin is either. So as we walk through the further expansion of largest customer, along with the synergies related to 2600Hz, I think second half of next year is a good point to start to see some improvements on the subscription margin.
There are no further questions in the queue. I would now like to turn the call back over to Eric for closing remarks.
Well, thank you, everyone. We've gone the full hour, so I won't say more, but I appreciate your attendance today. Thank you very much. Bye-bye.
Ladies and gentlemen, this concludes today's conference call. Thank you for your participation. You may now disconnect.
