Tal Hayek

Good morning, everyone, and welcome to our Q4 and 2021 investor presentation. My name is Tal Hayek, and I'm the Co-Founder and CEO of Acuity. And I'm very happy to be here live from our Toronto office after many quarters that we were not here and the office is alive again, full of energy, and I can't even describe, I have to see that. I'd like to start by thanking the Acuity family for delivering an amazing year. We've seen a year of growth of 16% on a year-over-year basis. We've seen illumin numbers grew by 37% in Q4 alone, sequentially, and 580% year-over-year growth. Now we can compare it on a year-over-year basis at our fifth quarter and on the illumin side. So look at those numbers grow. Our expectations when we launched illumin, which is to reach about $10 million in the first year. And last year alone, we reached $26 million. So illumin went from 0 to $27 million in just 5 quarters. Brand-new product that was launched in Q4 of 2020, already $27 million in that 5 quarters. What an amazing achievement to celebrate. In Q4, our overall revenue was up by 5%. Well, that was below our expectation. The majority of the reasons are things like the supply chain issue and slower travel and hospitality sector that is coming back, but still hasn't come back like we're expecting it to come back by now. Overall revenue was $122 million for the year. Well, that's a growth of 16%. But when you look at it on a constant currency basis, it's closer to 24% growth. And why is it important to look at it this way, because our -- most of our revenue are in U.S. dollars, and we're reporting in Canadian dollars. So if you really want to know the true growth rate, look at our constant currency numbers. In Q4, we delivered $36.8 million, 5% growth and a constant currency growth of close to 8%. That was below our expectation. And as I said before, some of the reasons are supply chain issues and the travel and hospitality industry that is taking longer than we expected. Supply chain, I think it's pretty self-explanatory. We have a whole bunch of clients that are simply don't have products or not enough product to ship. So they're slowing down their spent. And we also have potential clients that are on the pipeline that are not closing as fast as we expected because, again, they don't have the product to ship. So that's those -- that part as well. Obviously, that's a temporary issue. We expect that to be resolved sometime this year. In addition to that, we have the travel and hospitality business that we were expecting to come back by now big time, and we'll share a little bit more information about that in a second. In Q4, 28% of our revenue was already from illumin. So we're starting to get to a place that illumin is more and more critical mass of our business. And we do expect in the second part of the year, it's going to be the majority of our business. In Q4, we had 62 clients using our new platform, illumin. That's 62 clients that are taking advantage of being able to connect the journey of their campaign and being able to really send the messages that they want to send to their clients as a journey and not send every message on its own. So that is something that's very important that more and more clients are taking advantage of. We've seen 26 clients, Tier 1 clients running on illumin in Q4. And we've seen some specific verticals that did very well. So we talked about the travel as it's coming back. And we've seen 831% growth. But it was only 3% of our revenue, as you guys may recall, before the pandemic, travel and hospitality used to be close to 30% of our revenue. So we do predict that it's coming back and it's coming back big time this year, and we will see that as a big growth driver. Another driver is health care. Health care has grown 256% in Q4 alone over Q4 of last year. It's now 11.4% of our business in Q4, and we again see health care to continue driving forward. Connected TV, connected TV is an integral part of what we do with illumin. It's easy to sell a connected TV campaign. But when you can put it on illumin, and you can see the effect of seeing an ad on TV to your ROI, that makes it a much more filling story, and we're seeing more and more of our clients resonating with that message. We've seen over 200% growth in CTV sales in this year or 2021 over 2020, and we expect that to be -- continue to be a driver for us in the future. And I'd like to share a little bit of the illumin success story. And today we will focus a little bit on our legacy clients that moved into illumin. So it's a bucket of 4 clients that used our system, our legacy system in 2020. They spent $2.4 million, and they moved to illumin last year. And then they spent $5.2 million, the same clients, and that's up 118%. We -- I'm telling that story because I do believe that as we get more and more clients moving from the legacy system into the illumin system, then we will see the average spend per client go on. And this is something we all at Acuity are extremely proud of, the growth rate of illumin. Again, we launched it 5 quarters ago and look at the way it's been growing. We've achieved $26 million in revenue in 2021 and product that is brand-new and just went to market very recently. So when we see all of these signs, it's so encouraging to us that we feel very comfortable that illumin is changing the world and it's time to invest more and more in it. So we are investing to meet the growing demand of the future. And the investment is really happening across the org. The majority of the investment is obviously happening in sales and in marketing, but also in research and development, in infrastructure, in people, in organization in general. And to be more specific, we're investing $11 million this year into that. And we do believe the results will happen in the second part of the year. And what is that result? Well, to be simply put, we believe that the top line growth this year will be 20% to 25%. Again, making those investments, we will see the top line -- the majority of the top line growth happening in the second part of the year. I'd also like to share that when you think about illumin revenue, I'd like to share that 70% of that revenue came from new business to Acuity, which means brand-new logo. That's been our focus from day 1, to bring brand-new logos to illumin. And the concept of illumin opened up a lot of new doors and a lot of new customers for us. And many people are asking us, when are you going to start switching more and more of your legacy clients into illumin. We're very close to it. Some of the reasons are; one, we've been focused on bringing new business in. But number 2, there's a whole bunch of features on the roadmap that are not completed yet, and we're working very hard to complete them. And without them, it doesn't make sense to transfer some of our legacy clients into it. Once we're in that position, which I do believe it's going to be in the second part of the year, we will be able to move more and more of those legacy clients into the illumin side. And then we expect the average spend per client to go on. I'd like to share that the bulk of illumin revenue is coming from managed service. Why? Well a few reasons. Number one, it's a brand-new product. It's a brand-new concept. So people are not using it, they don't always know how to run a fully connected journey. So we're doing it for them. They're learning a lot from it. We're learning a lot from it and making the product better. And we are -- the intent is to move them along and move them to the Self-Serve side very, very quickly. On top of that, I'm very happy to announce that we've made an investment into a dedicated sales team that only sell Self-Serve. I do think there's something to be said about focus. And I believe that this investment is already starting to pay off big time. So by next investor conference, I do believe we'll be able to share some more specific numbers. And I do believe that people are going to be very happy with the results that we're showing out there. With that, I'd like to introduce Elliot, our CFO, to share some financial results.

E
Elliot Muchnik
executive

Good morning, and thank you for joining us today. I'm pleased to present our Q4 and our full year results, which are driven by strong illumin growth and a continued economic recovery post pandemic. Today, our focus is on 2021 financial results, but we are extremely excited about what lies ahead in the second half of 2022 and beyond, as investments we made in Q4 and continue to make in early 2022 will begin to contribute to growth in revenues and profitability. As we move forward, we are dedicated to expanding the reach of our unique and industry-leading technology platform to advertisers throughout the world. And on that note, I would like to discuss our financial results for Q4 and fiscal 2021. In Q4, the total revenue is $36.8 million, which is compared to $35.1 million in Q4 2020, which is up 5% year-over-year. Non-illumin revenue, which includes managed service and Self-Serve was $26.6 million in Q4 2021 compared to $27.8 million in Q4 2020, a slight decrease year-over-year. We attribute this decline to the adoption of illumin by legacy clients as well as select industry verticals that are still recovering for the pandemic. And revenue from our illumin platform totaled $10.2 million, up 37% sequentially compared to $7.4 million in Q3 2021, and it's up considerably from our first quarter of illumin revenue of $1 million at the end of 2020. Gross profit or net revenue was $19.1 million in Q4 2021 compared to $18.3 million in Q4 2020, a 4.8% increase year-over-year. Gross profit margin or net profit margin was 52% in Q4 2021, which is in line with our Q4 2020 margin of 52.1%. Total operating expenses for the quarter totaled $16.3 million compared to $11.7 million for the same period in 2020, an increase of 39%. And operating expense as a percentage of revenue was 44.2% for the quarter compared to 33.3% in the prior year. I would like to discuss the key drivers of this increase in operating expense. Primarily, the increase was driven by a $1 million increase in headcount costs driven by higher commissions tied to higher overall annual revenues, new hires in sales, technology and administration and an increase of $0.5 million for travel and entertainment as we return to pre-pandemic level of sales-related activity. In Q4 2020, our costs also benefited from the forgiveness of a pandemic payroll loan of $1.8 million. This onetime benefit was recorded in Q4 2020 and applied against our U.S. payroll costs. This is also a material driver of our year-over-year comparison. And finally, balance of the increase in operating expenses was driven by a return to our offices and related costs plus increases in year-over-year run rates related to our NASDAQ listing earlier in the year, including, but not limited to, insurance, listing fees and professional and advisory fees. Our adjusted EBITDA in Q4 2021 totaled $5.9 million compared to $7.8 million in Q4 2020, a 24.9% decrease quarter-over-quarter. This decline is related to our strategic investments to drive illumin's future growth that we discussed earlier as well as the factors that I mentioned impacting our overall OpEx, specifically the loan forgiveness of $1.8 million. Net income for Q4 was $2.5 million compared to $4.2 million in Q4 2020. For overall fiscal 2021 results, total revenue was $122 million, which is up 16.3% compared to $100.9 million in 2020. This includes $26 million in illumin revenue for the full year, which considerably surpassed our own internal target of $10 million. We are very proud to have achieved this rapid growth in 2021 despite the supply chain and COVID-related headwinds we encountered. Our gross profit or net revenue in 2021 was $63.6 million compared to $54.1 million prior year or up 17.5%. Gross margin was 52.1% for the year compared to 51.6% in the prior year. And our total operating expenses for the full 2021 year totaled $54.2 million compared to $47.1 million in 2020, an increase of 15%. This increase related in part to the investments I had mentioned earlier that will support our future growth and the variances discussed during the Q4 overview, but to a larger degree, specifically for travel and entertainment, insurance and our listing fees. Operating expenses as a percentage of revenue in 2021 were 44.4% compared to 44.9% in 2020. We generated adjusted EBITDA of $20.3 million for the full year, up 28.3% from the $15.8 million we generated in 2020. And net income for the full year 2021 totaled $10.6 million, which is an increase of 186% compared to the net income of $3.7 million in 2020. Moving on to the balance sheet. As you could see on this slide, our cash balance as of December 31, 2021, stood at $102.2 million, a considerable increase from the $22.6 million as of December 31, 2020. And this increase is largely due to the proceeds from our successful cross-border public offering in June as well as additional cash flow we generated during the fourth quarter despite increased spending in the latter part of the year to further capitalize on our unique consumer journey platform, illumin. I'm very happy to report that Acuity's balance sheet is now at the strongest level in the company's history. For some additional corporate data points, as of December 31, 2021, Acuity had 60.7 million common shares outstanding or 64.4 million on a fully diluted basis, translating into a market cap of just under 200 million. Insider ownership is at approximately 12% of issued and outstanding shares. In summary, while we saw lingering effects of the pandemic, we're extremely proud of our strong revenue growth in the fourth quarter and for the full year. Given our performance and the continued sales momentum driven by illumin, we're comfortable with reiterating the previous guidance we provided for fiscal 2022. Our top line growth is expected to grow organically by 20% to 25% for the next year. We're taking a conservative approach as we not only see continued effects of COVID-19 on key client segments, uncertainty around the macroeconomic outlook and inflation as well as overall geopolitical uncertainty. Supply chain issues are likely to be exacerbated given the tragic events in Ukraine. On a more granular level, we expect revenue growth to be more weighted towards the second half of the year. And based on our current pipeline, we expect modestly lower Q1 revenues on a year-over-year basis. This is reflective of both a return to more normal pre-COVID seasonality, continued headwinds from supply chain and the surge of the Omicron and Delta variance in late Q4. And also, in Q1 2020, we benefited from the concentrated spend from a one-off large campaign around legislative change around delayed tax filings. And as we move through the course of 2022, we will continue to invest into our platform and capabilities. 70% of that investment will be directed towards sales growth by increasing our presence in key markets. And the balance of the investment is focused on research and development growth to enhance the illumin product to support new client relationships and increase data throughput capacity. And these investments will impact 2022 by approximately $11 million. Again, the majority of which is driven by new hires and investing in our brand presence and reach. We expect to hire almost 90% of our hiring target by the end of Q2. And this upfront investment will temporarily exacerbate the impact of our initially lower revenues on EBITDA. But despite these short-term effects, this upfront investment will ultimately set the stage for both delivery and supporting the increased level of activity and market demand that we have experienced over the previous quarters. And overall, we expect 2022 EBITDA to increase by 10% over the prior year. Furthermore, we remain steadfast in our acquisition strategy and hope to add to the Acuity platform during the course of the year. We are currently evaluating several accretive opportunities and look forward to providing you with updates on our progress. And with that, I would like to pass it over back to Tal for his concluding remarks. Thank you.

Tal Hayek

Thank you, Elliot. As you can see, we are super excited about the illumin adoption. We believe that we will see 20% to 25% top line growth this year, and the majority will happen in the second part of the year. I want to reemphasize that illumin over-exceeded our expectations after we launched it, and we're ready for it to over-exceed our expectations again. And it leaves us very comfortable in making investments in the future, investments in growth. The majority of our investment is happening in sales and marketing. I want to share something. In the past, it was very hard for Acuity to come into a, let's say, new geographical market and hire the best of the best people in that market. So what we did is we went and we hired amazing people, and together, we developed them to be superstars. And today, the situation is a little better. We can come into a market and hire existing superstars. Why? For 2 main reasons. Number one, we have the budget. But that's a small part of it. The big part is we have illumin. And I tell you, as soon as we demo illumin to that salespeople that thinking about joining illumin, and if they had any doubts in their mind, that's the moment that they changed their mind because illumin is the one that sells everything. It shows them the future of advertising, and they want to be a part of it. So we're so glad to report that we have quite a few salespeople that we've made a hire to that are the best of the best in the field. And when you do those kind of things, there's always a lag. We're very happy that those people are taking a chance of us because they are taking a chance, leaving a very successful job with a huge book of business and coming to a new business is always a risk. But they're taking that risk because they see the future, and they see the very bright future of illumin. The lag that I'm talking about, I do believe is going to be smaller than normal because of the level of people that we're getting in. And therefore we will see major results in the second part of the year. From the $11 million investment we're making, 70% of it will go into marketing and sales. With that, I would like to thank you all for joining us today. And Elliot and I would like to welcome you to our Q&A section.

Operator

[Operator Instructions] Our first question comes from Aravinda at Canaccord.

A
Aravinda Galappatthige
analyst

Congrats on a robust quarter under difficult conditions, I suspect. 2 for me, I'll stick to that to a limit. The first is where Tal actually left off on the development of the sales team. Can you just give us a sense of what proportion of the expanded sales team you've hired so far? And a little bit more about sort of the makeup of the sales people that you've hired. Are these individuals with existing enterprise relationships that they can kind of bring into Acuity? Or is it -- will they sort of be -- would these accounts be sort of relatively new to them, but with obviously a lot of sales background? That's my first question. And my second question is for both Tal and Elliot. Given where the share price is, given where your cash is and given the very specific guidance you've given, is there a temptation to maybe consider share buybacks? I know that you've raised and you're looking to grow maybe some M&A, but given the variance of what I think most pedigrees of intrinsic value of the stock and where it is, is that a discussion that you're having at this point?

T
Tal Hayek
executive

So yes, so regarding the sales org, we've done a lot of changes in the sales org from reorganizing it to splitting it up and having a Self-Serve team now. And after we've done that, we started going and hiring people with books of business. So to answer your questions, everybody that we're hiring now, they have a book of business. They're very experienced people. They have deep relationships, and that's why we expect the normal lag that you have for salespeople to be much, much shorter. And obviously payback is faster. And as I said before, it was tough for us to hire these types of people in the beginning because budget issues, but mostly because we didn't really have something to wile them with. And with illumin, it's something that everybody wants to come and join the -- what we're doing because they see what it's doing for the future. So that's where it is from a sales perspective. Now you asked about the share buyback. And you and I have talked about it before, and we were generally against it because we want to use our cash for growth. But when we talked about the share price was in a different place, and now it's becoming to a place that it's starting to be very hard not to do it. So I'm going to say that we are now in very, very serious discussions with our Board and strongly considering it. And we will share the news obviously when we make a final decision. But I can't see anything more attractive to buy right now than Acuity.

E
Elliot Muchnik
executive

Aravinda, you asked that from a percentage perspective, about 2/3 of our target for the sales account have been hired despite challenging market conditions, but we've been very successful in attracting those set of professionals.

A
Aravinda Galappatthige
analyst

Was some of that already in the Q4 numbers as well, some of that spend or not really?

E
Elliot Muchnik
executive

Very little. People joined us late in Q4, so the impact was minimized on Q4, with the majority in the next year, the current year.

Operator

Our next question comes from Laura Martin at Needham.

T
Tal Hayek
executive

And while we wait for Laura to come on, I'd like to share with everyone that we are live from the Toronto office. Very, very exciting time here at Acuity to see the office full of energy and live again. So a good indicator that the world is back to life.

L
Laura Martin
analyst

So I have a couple -- I'll just ask 2. I have 10, but I'll ask 2 because that's the rule. So the first one is, we saw total revenue for the year about 16%. It went to 5% growth year-over-year in revenue. In the fourth quarter, you're going to go negative revenue according to Elliot's comments. So my question becomes, what gives you confidence you can hit your full year number given the decel we've actually seen in the P&L near term? Let's start there.

T
Tal Hayek
executive

Yes. There's a few things, okay. So let's talk about Q1. So in Q1 of 2020, we had one very large seasonal client that did not renew due to agency -- switching agencies and so forth. That was a very large client. If we actually isolate that number, we actually would have seen growth. But putting that aside, we're fairly happy with what's happened in Q1, just because of what I just mentioned. But on top of that, when we talk about the $11 million of investment that we made, I remember, 70% of it went into marketing and sales. We haven't made investments in our -- in that type of growth for many, many years, we're really focusing on the EBITDA part. And now that we -- number one, we've proven that the illumin story resonates with the market. So we're very comfortable making those types of investments in the future. So all of that money going into marketing and sales is going to accelerate our growth. And because there's a lag time every time you make those types of investments, we see that happening in the second part of the year. So that's -- now, we're already seeing great results, #1 from our hiring. We hired great people. So -- and looking at our pipelines and looking at our closed sales, our annual closed sales already, all the indicators are that we will have that 20% to 25% top line growth this year.

L
Laura Martin
analyst

And then, Elliot, on your comments, I just want -- maybe a couple for you. Actually, I'm going to try to cram them into my second question. I thought what I heard you say, Elliot, is that illumin lowered your year-over-year margin. And I would have guessed that illumin would have increased your margins. Did I misunderstand that about when you said the transition to illumin lowered your net revenue margin?

E
Elliot Muchnik
executive

I don't believe it actually did, even if that's what I have it came across, but I don't believe we said that, maybe that was a misunderstanding. But illumin has not. We still see these very similar margins across the board. I'm very confident in the underpinnings of our ability to buy media well. And so that hasn't happened yet. We do expect that as we move more into what Tal said about self-service that we'll see a decline in our margins. So you'll see that as a proportion of Self-Serve illumin growth for sure.

L
Laura Martin
analyst

And then what's the CTV? Just a housekeeping thing for you. What -- how much CTV, I saw in your slide, it was up 251% for CTV for 2021. What was CTV revenue in the fourth quarter or '21, whichever one you have off the top of your head or both?

E
Elliot Muchnik
executive

I think we're comfortable with saying that we believe that this year, it's going to be about 10% of our revenue. So that should give you a good indicator of the numbers.

L
Laura Martin
analyst

But you're not going to give us last year, right?

E
Elliot Muchnik
executive

We didn't [indiscernible] last year, no.

Operator

Our next question, dialing in by phone, comes from Drew McReynolds at RBC.

T
Tal Hayek
executive

Thank you, everyone, for joining us by video. I know this is something we've been trying for the last few quarters, and we're getting really good feedback for that. So we appreciate all the analysts coming on and cooperating with video. It's a little bit outside the box, but we love seeing your faces.

D
Drew McReynolds
analyst

A couple for me. Maybe first, Tal, just on the M&A side. Just maybe provide an update on just the environment out there, things that would be of interest to Acuity. And just within the context of a quickly changing market in all aspects out there. Secondly, just on illumin, and I'm obviously the new kid on the block here from the analyst perspective. In terms of modeling the revenue contribution from illumin, is there kind of a target percentage of revenues? I think in your remarks, you spoke to maybe the majority of revenues coming in the back half of 2022, but I may have missed that. So just trying to kind of level set expectations here on the revenue trajectory for illumin. And then third and final, in terms of the reinvestment, I think, Elliot, you kind of widely communicated that ramp-up. If you get the success that you're anticipating in the back half of 2022, should we expect another kind of ramp up in reinvesting in the business to go and capture incremental growth looking into 2023?

T
Tal Hayek
executive

Okay. Great questions. Let's start with the M&A one. So we've seen a lot of activities in the last few weeks from the M&A side. Some of it is due to our efforts. So we set up our own team here, and we hired a consultant in Europe that is actively going out and looking for targets for us. We're also looking at many targets in North America as well. So we're looking at many. We're having many conversations. There's nothing imminent at the moment. But what I would say is I do think it's a better time now. The valuation expectations definitely came down. And there are some great companies out there that we can do a lot together with them and add a lot of value, strategic value and financial value to us. So I'm very encouraged with the science of what we're seeing and the pipelines on the M&A side is just getting fuller and fuller all the time. So obviously, something that we really want to do this year. But we're always very cautious not to make a mistake there because the mistake there is it could be a big mistake. So we've done 4 acquisitions to date. All of them were successful. We have a lot of experience with it by now with the integration and everything, and we know exactly what we're looking for. Illumin, you asked about the illumin dollars. So 28% of the revenue in Q4 was illumin. We're seeing that continue to grow. So the percent of revenue, illumin will grow every quarter, I believe, every quarter. By the second half of the year, I believe it's going to be the majority. So over 50% of it is going to be illumin. And our intent is to start transferring people from the legacy system into the illumin system later on this year and at some point to turn off the legacy system. We don't know exactly when that's going to be. Again, the intent is, hopefully, by the end of the year or there's going to be a very small amount of people left on the legacy system. We do expect the customers that we move to illumin that we're going to be seeing an increase in average spend. So there's an upside there. And obviously, we'll keep adding more and more new deals, new logos, new companies into illumin. On top of that, we're making all of those investments, the new salespeople that has new relationship, that's making the new introductions, and we're investing in the marketing and the brand. So more leads are coming internally. So all of that is a great recipe for success. And then you asked an interesting question, you asked if the investment pays off. I hate that word if. I would say when this investment pays off because we thought very hard and long before we did it, and we are very confident that it's going to pay off. We're only going to see a fraction of it happening in 2022. The majority of the payback from that is going to happen in 2023 without any further investments. We could make a decision to invest more and to hire more people on the sales side. And that could be a very logical decision. But because of the lag time, most of -- like it's going to affect some of this year, but the majority of the payback is happening in 2023. So 2023 is going to be even more aggressive growth. I hope that answers the question.

Operator

Our next question is going to come from Eric Martinuzzi from Lake Street.

E
Eric Martinuzzi
analyst

I'm trying to better feel for the seasonality of the revenue during the year. Obviously, you've given us a full year number of about $150 million, and you've given us a Q1 that's down slightly year-on-year. But if I could look at it maybe on a first half, second half, and this is for either Tal or Elliot, is it kind of a 40-60, 35-65? Help me with the seasonality of the revenue during the year based on what you see now.

T
Tal Hayek

So we're not really breaking our soft guidance into those kind of numbers. But if you look at our historicals and historical in the ad tech, in general, again, I'm not giving you exact numbers. But I think the number is usually 40-60. Maybe it's just slightly under 40 for the first half and slightly over 60 for the second half. But again, I'm not looking at concrete numbers, but I think that that's what you will find if you look at historical.

E
Eric Martinuzzi
analyst

Yes. And I fully acknowledge the large seasonal customer you had in the year ago comp that makes it a little bit more difficult than maybe in a normal year. And then second question for me on the adjusted EBITDA. You talked about revenues down potentially in Q1 here. A year ago, we had adjusted EBITDA of -- I've got $4.5 million here on revenue of [ 274 ]. Should we assume the same kind of -- if rates are down here in Q1 of '22 slightly that the adjusted EBITDA will be down slightly as well? And then can you size that? Can you put a number on it? Or is it just too difficult?

E
Elliot Muchnik
executive

Q1, you're referring to Q1, Eric, of course.

E
Eric Martinuzzi
analyst

Yes.

E
Elliot Muchnik
executive

Yes. So for Q1, we expect it to be lower than the prior year from a relative perspective because of the investment that we're making and the lower revenues that we've guided to. So for Q1, our EBITDA will be substantially lower than the prior year. But by the end of the year, which is important, we expect overall EBITDA to grow year-over-year by 10%. So again very…

E
Eric Martinuzzi
analyst

But still positive in Q1 of '22.

E
Elliot Muchnik
executive

We believe very close, yes. Very -- we believe that it will be a lower EBITDA, but it should be positive.

T
Tal Hayek
executive

Eric, just to add to that, remember, we were not on the NASDAQ in the Q1 EBITDA the year before. The NASDAQ itself has naturally a lot of expenses, mostly from an insurance perspective.

Our next question is going to come from Dillon Heslin at ROTH.

D
Dillon Heslin

First, on illumin, how much of that growth is coming from moving some of your legacy customers onto illumin during the second half of the year? Like what's organic from new pipeline versus customers that you're switching over? And then I think you mentioned in 2020 versus 2021, those that you did switch, their spent was about of 100% or 118% in dollar terms. Like is that a realistic expectation for what you see going forward?

T
Tal Hayek
executive

So the percentage of -- so 70% of our revenue for illumin so far came from brand-new business to Acuity, right? So that would leave about 30% that moved over. So that's your first question. The second was, yes, we saw -- when we look at the group of 4 customers that switched in -- from 2020 to 2021 from the legacy system to illumin, we saw 118% increase in spend. Is it realistic to see it for every customer? Probably not. Is it realistic to see it for some clients? Absolutely yes. Remember that when you run a campaign on illumin, you're running a full final campaign, which is very different than just a lower funnel that people normally do on DSPs. So therefore your investment in the campaign is usually larger. Now there are customers who are going to use illumin just for the lower funnel part, which is, for us, it's a shame because it's not using it to the full potential. But there are still customers who are used to doing it that way. And those customers will see more or less the same results. So I do believe the average spend for clients will go up. And it potentially will go up 118%. But probably the average is going to be lower. The average increase will be lower than that.

Our next question is going to come from Rob Goff at Echelon.

Tal Hayek

I'm just interested to know how many people are working out of the office and how many people are working from home these days.

R
Robert Goff
analyst

Congratulations on a very solid quarter. I'm pleased to see the revenues, very pleased on the margins. With respect to your revenue guidance of 20% to 25%, just mathematically, if you're starting off lower on the first quarter, would it be fair to say that you look to exit the year pushing 30% revenue growth that would make sense?

T
Tal Hayek
executive

I didn't run the exact numbers, but obviously, it's going to be more aggressive growth at the end of the year in order to achieve those numbers.

R
Robert Goff
analyst

In looking at the composition, exiting the year, you've indicated more than half of the revenues exiting would be from illumin. You've also indicated that CTV could be roughly 10%. And I know there are some overlapping CTV and illumin. Could you talk to the reasonableness of illumin plus CTV exiting the year being more than 60% of revenues?

T
Tal Hayek
executive

Again, it's hard to tell because it's a little bit far away, but my best guess is that absolutely, like we're going to be in a run rate of more than 60% in the last quarter.

R
Robert Goff
analyst

And then just one last if I may. With respect to the revenue guidance there, what sort of recovery would it be reflecting in the COVID sensitive areas? And would it reflect any very significant illumin contracts? I know the sales cycles there are longer, but if you could address that, it would be very much appreciated.

T
Tal Hayek
executive

So it's -- I would say that when we're thinking about the one sector is the travel and entertainment, we see that that's coming back. Now we're not thinking it's going to be 30% of our revenue this year, but it's going to be a more significant part. And so that's a great upside. At the same time, there's other industries like we shared like the health care that is something that always does well, right? So with profit, without profit, it does well. And more and more of the budget is going online and more and more of the budget is going programmatic. So I don't think we're so dependent on specific industries coming up. Also, our sales team is very agile. Even when the pandemic started and we lost 30% of our revenue, more than 30%, 30% on the travel and entertainment, right away, they started shifting into health, into retail, into all of these other things that recovered us very fast from that downturn. So in general, I would say that we have a very good team and a very good product. And if things change to more pandemic or more issues with war issues or anything else that would lead for specific verticals not to do well. We are very well equipped to move to other verticals that will do well.

E
Elliot Muchnik
executive

And Rob, we did not assume any large wins. We've taken a very conservative perspective there. We think we're making terrific progress, but we also know that that is, like you mentioned, longer sales cycle. So in our assumptions, we did not assume that, although we would be very pleased to see that occur. But we are just basing it on a more kind of constructive and more of a conservative approach to our forecast.

Our next question will come from Daniel Rosenberg at Paradigm.

D
Daniel Rosenberg

I had a question around privacy regulation. I was just wondering if you could provide some commentary on any changes on how you view the impacts of big tax, privacy changes on your business since we last spoke.

T
Tal Hayek
executive

No. I always like to go back to the way that the open Internet operates, right? So we can go into details on how to do things and how it's going to get done and all of that. But I think the better way to approach it is how does it work? And how does it work today is all the content is being provided free for consumers, and it's being paid for by advertisers. My personal belief is that consumers are not going to start to pay for this content that they're getting for free today. And therefore it has to be -- continue to be subsidized by advertisers. And therefore the advertisers -- and we will have to show relevant ads to the consumers. So having said that, we will be able to find a mechanism to do it. Today, there's no issues, like we can fully do that. There's always been talks about either the cookies or IDFA and all of that other stuff. At the end of the day, we're not dependent on IDFA. The cookies have not -- are not going away as we know for about 2 years and then it's very doubtful if they're ever going to go away. But even when and if they go away, we would switch to either the universal device ID or any of the other partnership that we're doing and developing with our suppliers, our customers, the vendors or even our competitors, we're working on a regular basis to build those systems and there's going to be a replacement. So that's where I believe it's going to take us. The cookie has been tried -- the third-party cookie has been tried to be taken away for over 20 years now, and it -- unsuccessfully because the Internet needs it at the moment. So if we make changes to that, we also have to make changes in other ways that we will be able to deliver even in a better way.

D
Daniel Rosenberg
analyst

Sure. So I mean, certainly agree that the risks are manageable and a solution will come. But in terms of actual expectations around exposure to any immediate changes, if -- whether it be on Android phone tracking or if in 2 years from now cookies do come. Any commentary you could give around how dependent are you on these things and the preliminary test maybe you're running with other alternatives?

T
Tal Hayek
executive

So I think that's -- look, for example, when Google made their change, and people who are really dependent on the traffic on their apps, they were hurting. We don't do any -- less than 1% of our traffic is on apps. So we were not really dependent on it, and it didn't really affect us, right? So the biggest impact that could happen to us is a cookie issue, right? And we -- so that's what we really, really are working towards to solve. And we're doing that by replacing it with some type of universal ID. We're working with many companies to do it. And we have our own universal ID at the backend that matches them all together, so we can figure out who the people are. And in fact, the universal ID for me is a better solution than the cookies because now we don't have to guess that you're the same person on your mobile device, on your computer, on your connected TV, you're all going to have one universal ID that connects you. So that's -- in my opinion, that's where we're going. And therefore I don't believe there's a revenue impact on Acuity.

Our final question comes from Kevin Krishnaratne at Desjardins.

K
Kevin Krishnaratne
analyst

I had a question for you on illumin, the illumin wins, maybe the conversations you're having with the clients that are spending on illumin. Any sense of how you're being viewed from a competitive point of view? Where is this budget coming from in your view? Is it are clients simply expanding their budget? Or do you think you might be winning some share from a company like The Trade Desk, for example? Any commentary on essentially how you're stacking up now that it's been 1 year with the product against some of the bigger guys out there?

T
Tal Hayek
executive

Yes, I would say both. So some of it, the budgets are coming from the general spend, and they're just allocating it to illumin. They're seeing what are the results. They're seeing the insights they're getting from it. They're spending more on it and they're liking it. Some of it -- budget is coming from innovation. So it's all about trying new things and learning new things. And an increase in budget in general as it comes to the -- to what you spend on the Internet. So -- and don't forget that ROI is also very important to them at the end of the day. So when you deliver that ROI, then you get more and more of their budget. So it's a combination of all of it. We're definitely taking some business from other companies. We're definitely capturing some of the incremental spend that people are spending and the things that we're trying to do for innovations.

K
Kevin Krishnaratne
analyst

Well, it's good to hear that there's some -- potentially some competitive displacements there. Sort of a part B on this question is just I'm trying to understand illumin. I would think the consumer journey and the way the product is designed that there should be -- how to think about the amount of CTV that you're driving on an illumin win? Is it 1/3 of a client budget spend on a campaign coming from CTV? Is it more? It would seem that you should be getting a bigger portion of CTV when you're winning in illumin. Any thoughts there?

T
Tal Hayek
executive

Kevin, I'm not sure if we can see what's happening behind us, but there's a room that's full of journey. And there are 3 sections to it. It starts with awareness, then it goes to engagement and then it goes to conversion. So -- but awareness is usually the piece that you would see the CTV on and awareness is usually the biggest investment of the campaign because once you move people from the awareness, you may have a million people on the awareness side. And then you decide which ones are moving into the next stage. And it's substantially a lower amount of people, let's say, 20,000 people that now are aware of you, and now you want to engage them more. And then you start engaging them, that could still be with videos, but it could be a combination of many things. And then once they're fully engaged, all you want to do is bring them back to the website to convert them, right? So -- and that's even a smaller amount of people. So it could be more than 30% of the budget between, let's say, video, online video and CTV. But every campaign, a lot of it is about the algorithm, making decision and seeing what works best for that specific campaign. So I'm sorry, I can't give you a general rule of how much CTV per campaign. I can tell you that it's very effective. It's easy to see that it's effective when you're using illumin. If you're just running CTV, it's very hard to see. So that's why people really, really like it as a part of the campaign.

K
Kevin Krishnaratne
analyst

Yes. No, got you. So look forward to hopefully pushing much higher than 10% CTV growth over the coming back half of the year. Just a last question. As you think about -- a lot of people have asked about the guidance forming for 2022 and maybe just more Q1 and Q2. Can you talk about anything on Europe, I think Europe is maybe 10%, maybe a little higher than your revenue. Any just thoughts on client discussions there, given what's happening in the region right now would be helpful.

T
Tal Hayek
executive

Yes. So Europe, as you know, we have a location in Barcelona. It's doing well. It's growing. It's delivering its numbers. We're actually seeing more and more Self-Serve clients coming out of that region. We don't really see so far any effect as for what's happening in the region. So it's really hard to say. Nobody knows what's going to happen next. So far, we haven't seen any serious effect on revenue.

K
Kevin Krishnaratne
analyst

Good to hear. Yes. So the client -- the discussions with clients, they're spending, it's just as expected?

T
Tal Hayek

Yes, absolutely, absolutely. Yes.
