Good day, ladies and gentlemen, and welcome to Ziff Davis Q4 and Year-End 2021 Earnings Call. My name is Paul, and I will be the operator assisting you today.
(Operator Instructions)
On this call will be Vivek Shah, CEO of Ziff Davis; and Bret Richter, Chief Financial Officer of Ziff Davis. I will now turn the call over to Bret Richter, Chief Financial Officer of Ziff Davis. Thank you. You may begin.
Bret Richter - CFO
Thank you. Good morning, ladies and gentlemen, and welcome to the Ziff Davis Investor Conference Call for Q4 and Fiscal Year 2021.
As the operator mentioned, I am Bret Richter, Chief Financial Officer of Ziff Davis, and I'm joined by our Chief Executive Officer, Vivek Shah.
A presentation is available for today's call. A copy of this presentation is available at our website. When you launch the webcast, there is a button on the viewer on the right-hand side, which will allow you to expand the slides. If you have not received a copy of the press release, you may access it through our corporate website at www.ziffdavis.com.
In addition, you'll be able to access the webcast from this site. After completing the formal presentation, we will be conducting a Q&A. The operator will instruct you at that time regarding the procedures for asking questions. In addition, you can e-mail questions to investor@ziffdavis.com.
Before we begin our prepared remarks, allow me to read the safe harbor language. As you know, this call and the webcast will include forward-looking statements. Such statements may involve risks and uncertainties that would cause actual results to differ materially from the anticipated results. Some of those risks and uncertainties include, but are not limited to, the risk factors that we have disclosed in our SEC filings, including our 10-K filings, recent 10-Q filings, various proxy statements and 8-K filings as well as additional risk factors that we have included as part of our slide show for the webcast. We refer you to discussions in those documents regarding safe harbor language as well as forward-looking statements.
In addition, please note that these fourth quarter and full year 2020 and 2021 results are preliminary, unaudited and subject to adjustments. In particular, due to the complexity of the October 7, 2021, spin-off of Consensus and the related transactions, including the debt-for-debt exchange, the presentation of the transaction's impact on the company's financial statements including the presentation of continuing and discontinued operations and the size of the gain associated with the retention of 19.9% safety consensus is still being finalized.
Any change to the impact of the unrealized gain on investment of $290 million associated with the retention of the 19.9% stake in consensus would be material to our GAAP net income from continuing operations. As a result of the foregoing, certain information provided here and is subject to change.
Now let me turn the call over to Vivek for his remarks.
Vivek R. Shah - CEO, President & Director
Thank you, Bret. I've got to say, it's great to have you in our team. Good morning, everyone. We're very pleased to have capped off an exceptional 2021 with a strong fourth quarter. While the successful spin-off of Consensus justifiably garnered a lot of attention in 2021, Ziff Davis delivered exceptional pro forma results at the same time. Revenues of nearly $1.4 billion, up over 26% year-over-year and adjusted EBITDA of $485 million, up over 28% year-over-year. We also exited the year with the strongest balance sheet and deepest financial resources we've ever had. We posted over 10% revenue growth in Q4 with advertising revenues up 7% and subscription revenues up 15%.
As I described in our last call, we expected to see a deceleration in growth in Q4, with RetailMeNot lapping itself as well as a tough comp with strong online shopping season and the introduction of the ninth generation of gaming consoles during 2020's Q4.
On the advertising front, our growth was driven primarily by our health and wellness properties where we continued to see strong demand from pharma marketers looking to reach patients and physicians within relevant content. In January, Everyday Health announced the addition of Cleveland Clinic to its trusted care access portfolio. In a multiyear partnership, Everyday Health will exclusively represent ad inventory on clevelandclinic.org and bring first-to-market solutions to our advertising partners.
We're proud to have been entrusted to further the Cleveland Clinic's mission and support their best-in-class medical content. Our pregnancy and parenting business led by BabyCenter, has been increasingly active in supporting clinical trial recruiting and pregnancy exposure registries, including key COVID-related studies. Our shopping properties were slightly up in the quarter, even with RetailMeNot, lapping itself beginning in November and the tough overall shopping comp.
Advertising and gaming and entertainment was also slightly up, a year after the new gaming consoles were released and our B2B tech advertising continued its momentum from Q3 with strong ad revenue growth.
We continue to believe that our advertising franchise has some meaningful advantages. First, we match advertising to relevant content, not the behavioral data. In other words, our ads are placed based on the content you're consuming, not based on third-party data.
Second, we operate in high-value verticals like tech, gaming, health and shopping where there are endemic advertisers who value audiences exhibiting purchase intent.
Third, our advertising solutions attract large blue-chip marketers who tend to spend more consistently over time in small markets.
And finally, our advertising solutions are performance-driven, providing measurable results for clients. On the subscription front, we saw some very nice growth out of our connectivity businesses, with continued strength from our Ookla and Ekahau offerings. We also saw a nice boost to subscription revenue from the timing benefit of our Moz acquisition, which closed in June of 2021. This is an acquisition that we remain very excited about, as evidenced by the renaming of our marketing technology business to the Moz Group. The Moz Group now consists of an integrated portfolio of marketing technology offerings that includes SEO, e-mail marketing and second line voice services.
Our cybersecurity business was flat in the quarter. We continue to explore growth opportunities for the business. Our guidance for 2022 projects overall revenue growth of approximately 10% at the midpoint. I'll point out that we have not incorporated any future acquisitions into our guidance. Therefore, we are only providing an outlook for the businesses that we currently own. We will update guidance as appropriate if acquisitions materially affect our range.
We're projecting our advertising revenues to grow high single digits in 2022. We expect stronger growth in the second half than the first half for 2 reasons: first, Q1 and Q2 of 2021 were strong growth quarters for us, making the comps more challenging; second, as I discussed in our last call, we are cautious about the impact of supply chain disruptions on our advertising clients.
We are seeing campaigns being delayed and budgets being curtailed as some of our marketers, especially in tech and retail, are having production and fulfillment challenges. These delays aren't sector-specific because in the case of pharma, which is our single largest ad category, we are seeing no supply chain challenges whatsoever. We are projecting our subscription business to grow in the low teens with strong growth at our connectivity and martech groups, offset by some weakness in our cybersecurity group.
We see continued demand for our expanded set of offerings and connectivity from Speedtest to Ekahau to Downdetector to our most recent addition RootMetrics. We believe we are now the most complete source of broadband analytics in the market. We also project our Moz Group to have a very strong growth year with a combination of organic and acquired revenue growth. With respect to our other revenues, which are still very small at about 3% of revenues, we are seeing strong growth of over 50% with our Humble games publishing business continuing to drive this growth, with our newest indie hit, Unpacking, already selling over 300,000 units since its release in December 2021.
We continue to look for ways to scale our indie publishing operation. We are projecting adjusted EBITDA margins of 36%, which is about 100 basis points better than 2021. That translates into about 13% adjusted EBITDA growth at the midpoint. As you know, the company-stated goal is to double earnings every 4 to 5 years, which implies a 15% to 20% earnings CAGR.
Since 2012, we've done better than that by doubling earnings 3x. But this is not a linear endeavor. There is an understandable lumpiness that comes with a capital allocation and programmatic acquisition strategy. We invest our shareholders' capital responsibly and where we believe we can generate outstanding returns. If and when we consummate transactions in 2022, then it should only enhance our growth rates.
Let me provide you with an update on our ESG efforts. We're getting ready to publish our inaugural ESG report for 2021 in the next few weeks. The report will include findings from the company's first greenhouse gas inventory, which calculates our carbon emissions for 2019, 2020 and 2021. In doing so, we've laid the groundwork to set a science-based target. The report also reflects the company's efforts to align with GRI, SASB, and TCFD reporting standards.
In addition to our environmental efforts, we're also heavily focused on our DEI efforts. The report highlights key data points around our workforce representation, hiring and inclusivity and promotions among others. It also details the policies, programs and practices, which address the material topics most important to our company and its stakeholders.
In this realm, I'd just like to mention that Ziff Davis recently received a perfect score on the Human Rights Campaign's 2022 Corporate Equality Index, earning us the designation as a best place to work for LGBTQ plus equality. In some, we've made great strides in the company's ESG journey and look forward to publishing our upcoming report.
Lastly, in the spirit of Black History Month, I'd like to mention a few exciting initiatives. In 2020, Humble Bundle launched its Black Game Developer Fund, committing $1 million annually towards this unique program, which provides black game developers, the assistance and resources to create and publish games. Since its inception, the Black Game Developer Fund has signed and provided support to over 20 qualifying developers.
We've also continued our focus on health in equality in Everyday Health, with our Black Health Facts resource center. We have launched a new 6-part series on health change makers, celebrating those who have made a positive impact on the health and wellbeing of their communities and beyond. These are just a couple of examples of how Ziff Davis leverages its platforms to support communities and color.
Now let me pass the call back to Brent.
Bret Richter - CFO
Thank you, Vivek. Let's discuss our financial results. Our earnings release reflects both our GAAP and non-GAAP financial results for Q4 2021 and the full year 2021. Our earnings release also reflects pro forma adjustments for the impact of various asset dispositions, explanations for and reconciliations of these adjustments are provided in our earnings release. As you may recall from our previous earnings calls, we sold our Australian and New Zealand voice assets in August 2020 and our U.K. voice assets in February 2021.
In September 2021, we completed the sale of our B2B backup business. As a result, while certain of these divestitures impact Q4 2020, none of these divestitures impact our Q4 2021 results. On October 7, 2021, we completed the spin-off of Consensus. I'd like to recognize my colleagues at Ziff Davis and many of the company's former team members that joined Consensus for executing such an important transaction for our company and its shareholders.
Our GAAP income statement and balance sheet reflect the financial activity related to Consensus through October 7, 2021, in discontinued operations. We will focus our discussion today, and my commentary will primarily relate to our pro forma non-GAAP financial results from continuing operations, which exclude the contributions from the Consensus business for the periods up through the date of the spin and exclude the contributions from our divested businesses, the periods that they were owned by Ziff Davis.
Now let's review the summary of the quarterly financial results on Slide 4. We reported pro forma revenue from continuing operations of $408.6 million for the quarter as compared with $370.1 million for the prior year period, reflecting growth of 10.4%. Pro forma adjusted EBITDA from continuing operations was $161.6 million for Q4 2021 as compared with $151.3 million for the prior year period, reflecting growth of 6.8%. Our adjusted EBITDA margin for the quarter was 39.5%.
Let's turn to EPS. But first, I should highlight that our GAAP net income and EPS for Q4 2021 reflect the sizable gain associated with our retained stake in Consensus. As we have discussed on prior calls, we are pursuing alternatives that would allow us to achieve a tax-free disposition of our stake in Consensus. And as a result, our financial statements do not reflect taxes on this GAAP gain, resulting in a significant after-tax contribution from this gain to GAAP net income and EPS for the quarter.
This gain is not reflected in our adjusted non-GAAP earnings per diluted share. As for our adjusted non-GAAP earnings per diluted share, for the fourth quarter, we reported $2.17. This figure reflects a 0.5% increase as compared with our Q4 2020 pro forma results. Please note that our Q4 2021 EPS reflects the dilutive effect of the retirement of our 3.25% convertible notes earlier this year offset in part by certain recent share repurchases, which I will discuss shortly.
Turning to Slide 5. For our fiscal year, we delivered very strong pro forma growth in revenue, adjusted EBITDA and adjusted non-GAAP earnings per diluted share from continuing operations. 2021 total pro forma revenue grew 26.8% to $1.383 billion. Pro forma adjusted EBITDA grew 28.3% to $484.6 million and we had adjusted EBITDA margins of 35%. Pro forma adjusted non-GAAP earnings per diluted share grew 31.4% to $6.11.
On Slide 6 and 7, we have provided performance summaries for our 2 primary types of revenue. Advertising and subscriptions. In addition to the quarterly and annual revenues, we have also started disclosing new metrics related to these revenue streams on a quarterly basis for 2021. As you can see on Slide 6, Q4 pro forma advertising revenue grew 7% as compared with the prior period. Our annual advertising revenue grew 34%, net advertising revenue retention is an annual trailing 12-month statistic that we update quarterly.
Net advertising revenue retention compares advertising revenue generated by a defined group of advertisers in 1 trailing 12-month period to advertising revenue generated by these advertisers in the prior comparable period. Our goal is to have retention in excess of 100%, which we had in all 4 quarters in 2021, with Q4 coming in at a very strong rate of 112%.
In the fourth quarter, Ziff Davis had more than 2,000 advertisers with a quarterly spend of at least $2,500 each. Quarterly revenue per advertiser was at its highest level this year at more than $131,000.
Slide 7 depicts our subscription revenue performance. Q4 pro forma subscription revenue grew at 15%, the same level of subscription revenue growth that we achieved for the year. Subscribers were down slightly as compared to the year's prior quarters, primarily due to modest decreases at cybersecurity and Humble Bundle.
However, average monthly revenue per subscriber reached its highest level this year at nearly $20 per subscriber, with an increase of higher revenue value Moz and connectivity customers and our churn rate remained at 3%.
Slide 8 provides quarterly and year-over-year pro forma revenue growth rates delineated by organic and acquired revenue growth. Revenues from businesses owned for at least a full 12 months are included in organic revenue, while acquired revenues are from those businesses we've owned for less than 12 months. For the full year 2021, we achieved a 10% organic revenue growth rate. This rate slowed in the fourth quarter as expected because of RetailMeNot being included in November and December of both periods and the relative strength of IGN advertising during last year's Q4. If you exclude the impact of RetailMeNot and IGN, the quarter's organic growth was about 5%.
Before turning to guidance, I'd like to spend a moment on Slide 9, which depicts a number of elements of our balance sheet. Our balance sheet is extremely strong. And as discussed on prior calls, was enhanced through certain transactions related to the spin-off of Consensus.
We have significant cash liquidity with $695 million of cash and cash equivalents as of year-end, more than $350 million of short- and long-term investments and significant leverage capacity, both on a gross and net leverage basis. We continue to be committed to keeping gross leverage at 3x adjusted EBITDA or below, and we are currently well within this metric with year-end 2021 gross leverage of 2.5x adjusted EBITDA.
As of 2021 year-end, our net leverage was 1x and only 0.3x, if you include the value of our short- and long-term investments. We will continue to be thoughtful and opportunistic as we allocate our investable resources to pursue enhanced shareholder value. During the fourth quarter, we did just that. We repurchased $25.4 million of our 4% and 5.8% notes and repurchased $47.7 million of our common shares. These repurchase activities continued in the first quarter when we repurchased an additional $54.6 million of these notes and $58.7 million of our shares.
In all, we repurchased 1 million shares at an average price of $106.43, which is part of our opportunistic share buyback program in which we repurchased shares under return profile, we believe, is highly compelling. As you may recall from our prior calls, in order for the cash distribution that we received from Consensus to be tax-free to Ziff Davis. These proceeds must be used within 1 year of the spin for a specific set of allowed disbursements. These repurchases qualify. We also deployed approximately $30 million in cash for a number of Q4 and prior period acquisitions, again, all consistent with our balanced approach to capital allocation.
Moving forward, we will continue to consider repurchase activities that we believe are accretive to shareholder value, while seeking investment opportunities that we believe are particularly attractive opportunities for us to grow our business and generate attractive returns. I'd like to provide a few additional details related to our guidance, which is described on Slides 11 and 12.
Overall, our Q4 2021 preliminary unaudited results were consistent with or better than the midpoints of the guidance that we updated last quarter. With regards to our 2022 guidance, the midpoints of our revenue adjusted EBITDA and adjusted non-GAAP income per diluted share guidance, implied growth rates of approximately 10%, 13% and 9% as compared with the 2021 preliminary unaudited pro forma results from continuing operations that we presented today. We believe that these expectations are strong, particularly in consideration of the current business environment. With regards to certain details underlying this guidance, in 2022, we expect advertising revenue growth in the high single digits, subscription revenue growth in the low teens and other revenue growth of nearly 50%. Given the seasonality of our digital media properties, we anticipate that roughly 20% and 30% of our revenues will be in the first quarter and fourth quarter, respectively.
The company expects to have an adjusted EBITDA margin of approximately 36% for the year, post the spin-off of Consensus, which had a higher concentration of international revenue as compared with Ziff Davis, we expect our non-GAAP tax rate to increase. Many factors go into a projected tax rate, but we currently expect an annual rate of between 23.5% to 25%.
Note, these rates often fluctuate quarterly. Additional details related to our share-based comp and anticipated share count are outlined on the slides as well. Following our business outlook slides are our supplemental materials, including reconciliation statements for the various non-GAAP measures to the nearest GAAP equivalent. This section includes a GAAP reconciliation on Page 15 that reflects free cash flow from continuing operations and discontinued operations for 2021 of $402.5 million.
This figure reflects contributions from the disposed assets and Consensus through their disposal dates or the distribution date, respectively. Going forward, on an annual basis, we expect free cash flow to approximate adjusted EBITDA, less capital expenditures, interest and taxes, the impact of working capital and any sources and uses that are excluded from our non-GAAP financials.
Note that given the timing of interest, tax payments and changes in working capital, quarterly cash flows can fluctuate meaningfully. It's been a milestone quarter for the company, and we are excited to pursue additional opportunities in 2022.
With that, I would now ask the operator to rejoin us to instruct you on how to queue for questions.

And the first question is coming from Shyam Patil from Susquehanna International Group.
Shyam Vasant Patil - Senior Analyst
Congrats on the fourth quarter and the outlook. I just had a couple of quick questions. First question, Vivek, can you talk a little bit about the supply chain issues you commented on. I mean, certainly, those seem to be impacting a lot of companies in the sector. Maybe if you could talk about which businesses, which verticals, and then just your level of confidence that these will be a less of an issue in the second half?
And then second, on the M&A environment, just curious, just your take on whether or not the changes in the public markets and valuations that we've seen over the past few months. Is that something that you think helps you guys be more aggressive in terms of doing M&A? Or is that something that could potentially lead to a slowing? I mean, certainly you guys have been quite aggressive since you've been CEO, but just kind of curious on your take there.
Vivek R. Shah - CEO, President & Director
Yes, great. Thank you. So on your first question with respect to supply chain challenges, they manifest or would manifest primarily in our retail and tech categories. And the way that would work is that, look, and we saw this at the beginning of the pandemic where there were supply issues at a number of retailers and the retailers came to us and said, look, it's not useful for you to generate demand for products that we can't fulfill.
And so while we're not quite at that level of challenge, we are seeing signs of it. It is built into our expectations into our guidance really for the first to second quarter. But we're pretty optimistic based on the discussions that we're having with our marketing clients and our advertising partners that this will alleviate over time. I think also the tech hardware category, which is not insignificant for us, given that tech is an important category, though it is more software than hardware, I will point out, but you do have chip shortages and chip shortages also contribute to lack of availability.
So to answer your question, I think we have appropriately built in any potential challenges around supply chain into our guidance and remain pretty confident that over the course of the year, those will work themselves out.
Now on your second question with respect to the M&A environment, I do think you are right that generally speaking, there is more sobriety in the marketplace around valuations, which obviously always plays to our advantage as an active buyer of businesses. And obviously, right now, we're as well capitalized and positioned as we've ever been to execute against transactions. So that combination is frankly very exciting for us. And now with the team very focused on the acquisition program and system after a year, where not only did we have the spin-off of Consensus, we had a number of other dispositions. It was a very, very active transactional year. It wasn't an active acquisition year, which everyone has seen. And I think that energy that we were allocating to the various activities to spin off and to divest will show up in our M&A activity.
And I think it is a more benign environment for us. So that's what I would say. And I would also say -- and just to remind everyone that the way in which we source and generate opportunities is across every single business unit inside of every division and at the corporate level. And so that combination and that approach to sourcing generally yields a pretty robust pipeline of opportunities for us to consider.
Operator
Next question is coming from Cory Carpenter from JPMorgan.
Cory Alan Carpenter - Analyst
I have 2 as well. I think you were one of the few companies that guided some margin expansion this year. So just hoping you could talk about the drivers here and how you were able to alleviate some of the cost pressures other companies are seeing. And then I think, secondly, on M&A, hoping you could talk a bit about the acquisition of Emma's Diary that you announced a few weeks ago.
Vivek R. Shah - CEO, President & Director
Thanks, Cory. Look, I think that -- and I'm happy you point this out. We have always been careful spenders at Ziff Davis and we're really thoughtful about how we spend shareholders' money. And so we have been very focused on operating expenses and ensuring that we're seeing the appropriate returns from everything that we put forward and every dollar that we spend. And I think that the process around the Consensus spin also gave us an opportunity to really review everything.
And so it's not one thing. I think it's the continued mindset and ensuring that we stay at or above our target margins, which are in the mid-30s. And I'm glad that we've gotten -- we've arrived there sooner. And this is an environment where a lot of expenses are returning to the P&L and to the business, whether those are travel expenses, et cetera. I will also point out that our business model is generally particularly around the advertising model, a lot of the advertising revenues have high operating leverage. So the degree to which we can outperform in advertising. The flow-through to EBITDA can be quite attractive and it can be quite accretive then to the overall margin profile of the company.
On your second question around Emma's, we're really excited for the brand. As you may know, our parking and pregnancy business has been predominantly in the U.S., BabyCenter and What To Expect are very strong and very popular U.S.-based pregnancy applications and brands. Obviously, babies are born all over the world. And so we've had a real desire to start to expand our footprint and take our business model, our proven business model in the category to territories outside of the United States. The U.K. happens to be our second biggest territory, but much smaller, particularly for BabyCenter. And so the opportunity for us to expand in a market that would be a national market for us to expand, with a brand that is of the caliber of the brands that we own in its market and where we believe we've got a monetization formula and a business model that will help to unlock revenues makes it an exciting deal. It is small. It is not -- it is a small-ish deal, but I think it is representative of a little -- of our ambition in this category.
Operator
And the next question is coming from Dan Ives from Wedbush.
Daniel Harlan Ives - MD of Equity Research
So just on M&A, can you just talk about from a size of deals. Like is there an appetite to do some larger deals here, just given the position you're in whether it's -- you may be add another pillar. I mean how should we just think about that to the -- most of the year?
Vivek R. Shah - CEO, President & Director
Yes, Dan, it's a good question. And as I've said in the past, I guess I'll reiterate here. If there is a sweet spot of deals for this company over the last decade that has worked really, really well, sort of lower mid-market type acquisitions, and I think we're going to continue to stay there. I don't think our -- I don't think the fact that we have more capacity means larger deals, I think it just may mean more of the kind of deals that we've done, which we feel comfortable with, given that we have so many different business units that are competing for capital and have the wherewithal to create value from acquisitions.
I just think it mitigates our risk. It spreads our bets, and I think it feeds more parts of the company in a really healthy and productive way. Having said all of that, we are always open to a larger deal. Our level of confidence must be extremely high. And as you know, and think of those as more platform-type deals. We haven't done many, right? In the history of the company, I'd say the first platform deal with the acquisition of Ziff Davis itself in 2012, followed by the acquisition of the Everyday Health business in 2016 and then -- 4 years after that.
So it seems to happen on every 4-year cadence, there was the RetailMeNot acquisition. But in no case did we expand in excess of -- would have been $500 million or 10%, it's far less than 10% of the enterprise value of the company. I have had a sort of a threshold that we would never entertain anything that was in excess of 20% of the enterprise value of the company. But again, we haven't come close to that level of transaction. So I wouldn't conclude that given the healthy balance sheet, we are big game hunting. I think our hunting is the same hunting it's been. It's just we think we can -- we have the capacity to transact on more opportunities.
Operator
And the next question is coming from James Breen from William Blair.
James Dennis Breen - Communication Services Analyst
Just one again on the M&A side around the gaming industry. Obviously, we've seen some large M&A deals happen around gaming. Just any thoughts there, whether there's opportunity for M&A or potentially to sell some of that you have?
And then secondly on Ookla, with 5G rolling out and the government broadband build out, any additional inquiries you're seeing around that just for businesses to get more insight into what's happening in the broadband markets.
Vivek R. Shah - CEO, President & Director
Jim, these are great questions. So obviously, the gaming industry there has been a number of pretty high profile and significant transactions in the industry, which we watch with great attention, and we think it could yield actually more revenue and more marketing dollars unlocked, as some of these larger, more consolidated players tried to start to deliver on the promise of these combinations. So there could be some positive tailwinds around our assets with respect to what's going on.
I also think -- it shows up in our other revenues, which is still small, but our efforts in the Humble games publishing area also, I think, is beneficial as I think a lot of these larger platform companies want to continue to build their libraries and we'll seek in the publishers like us and our titles to add to their libraries. So we've become a little bit of an arms dealer to some of these platforms, which was something we were anticipating. So that also aligns, I think, with what we're seeing in the marketplace. And then remember, because we're largely games, media, yes, digital store front as well.
I do think that we can still transact in the space without being concerned about asset values, making it hard for us to acquire in the space. So I'm not concerned about that. On the aspect of can we unlock value, I would say this about all of our businesses, and I think demonstrated by what we experienced last year with Consensus. If we see an opportunity to unlock meaningful and sustained shareholder value through a separation, whether it's a sale or a spin or a carve-out IPO or whatever. We're going to continue to really ensure that if those are available to us, we will take advantage of those. And so I think we have our eyes open across our portfolio for opportunities like that. That's not a new statement. That's something we've always said, but I think given that we've acted in a meaningful way with the Consensus spend and the confidence that we frankly garner from that experience, we feel that there may well be opportunities like that, as we think about the company's portfolio. So look, I think that there's a lot to like.
Now you asked about connectivity in 5G. It is worth pointing out that the connectivity set of businesses, the Ookla, Ekahau group of assets are our fastest-growing assets, however you look at them organically, total growth et cetera. We executed a really important transaction strategically in RootMetrics. So for those who follow broadband, analytics and testing, there has been a long haul sort of bifurcation in the market.
There are those who believe in crowd-sourced testing and analytics, that's what we have historically done. Where individuals, test their speeds and the aggregate of analytics, help inform network owners and operators as to the quality of their networks as benchmarked against their competition. But there's also something called drive testing, which is to actually equip vehicles with devices and software to measure how those devices are performing in motion, driving along a highway. And that is drive testing.
We've never had drive testing, data or capabilities within this group. So the opportunity now to bring drive testing and RootMetrics is certainly the market leader in drive testing has been for a while. And I'm sure you've seen all the ads where people are promoting their RootMetrics scores, having that combination puts us now complete in terms of an analytics point of view.
We no longer are engaging in the debate of which is better. We have all of them. And so we have any and all views into network performance, which we think is going to be very powerful. And I think 5G just fills into that, right? These are our networks, how are they doing? Are they meeting the need? I think that's just going to open up even more opportunity for us.

And the next question is coming from Rishi Jaluria from RBC.
Rishi Nitya Jaluria - Analyst
Wonderful. I have 2 here, one for Bret and one for Vivek. For Bret, I wanted to maybe unpack the organic number a little bit. And obviously, the 2% is a little bit of a decel from what we saw in Q3 and Q2, but I wanted to understand maybe the drivers of that. Number one, we obviously don't have the compares from 2020. And I imagine the comparison in Q2 and Q3 were probably substantially easier than they were in Q4. So if we think about that, maybe how much of that is attributable to the tough comps? How much to the RetailMeNot and kind of the drag on organic growth that brings as well as maybe the tougher e-commerce season.
And then for Vivek, look, can you remind us what sort of impact you saw specifically from IDFA, especially in light of what we've seen for some of the larger Internet platforms for IDFA. And why you feel you're maybe a little bit more insulated from that impact than others in the space.
Bret Richter - CFO
Great. Thanks, Rishi. I'll take the question on organic growth, first. I think, first and foremost, Well, certainly, we're here and focused on the quarter, particularly our first quarter after the Consensus spin and emerging as sort of our new platform for growth I think there should be as much focus on the full year organic growth this fourth quarter, and we'll talk about the fourth quarter in a second.
I mean we did 10% organic growth for the full year, and that is a significant contributor to the overall value creation of our company in the past that we're on. And we talk about our growth ambitions, and we talk about being a total growth company, we generally think about getting about half of that growth from organic and half from M&A and of course, M&A feeds into all the questions that have been asked on this call and the timing and the nature and whatnot, but on a full year basis, our organic growth is strong.
With regards to the fourth quarter and, yes, maybe a lower rate. There are a handful of factors. One of those factors is we lapped RetailMeNot acquisition, and that leads into the equation. We had very tough comps from last year overall. Last fourth quarter, extremely strong for the industry and the company and IGN, dragged us down a little bit for the quarter as well. But overall, looking at the last 12 months and the growth that we put up, I really believe that's (inaudible).
Vivek R. Shah - CEO, President & Director
And then just on the question around IDFA and the overall ad environment. What I would say is that I do believe that the pendulum is swinging in our direction in that content-oriented and contextually driven advertising solutions are coming into favor. Where, as I described, advertising is placed against the specific content adjacent to specific content versus based on interest and data collection. And since IDFA was really designed on the changes with respect to IDFA to somewhat disable interest-based advertising targeting, that obviously has had a negative impact on the platforms that rely on it. That's not us.
And so from our point of view, the challenges relating to IDFA, third-party cookie deprecation and the overall market view of swinging back to being an environment that they value, premium environment, where the content and the factors of consuming the content indicate something about your purchase intent, that is what we do. And so I do believe that we're going to find ourselves in a favored position. I'll make one other point on this, which is some of -- all of the larger platforms have a full range of customers from large enterprise buyers of advertising, down to the smallest businesses.
And if you parse some of their challenges, it's been more on the long tail. Our advertising business is really ahead of the tail type business, over 2,000 enterprise-level buyers of advertising, which demonstrates far more retention and recurrence of revenue. I mean one thing I would say for those who watch the company and study the company, the net ad revenue retention statistics are remarkable, they are enviable no matter what industry you look like. Their SaaS-like revenue retention is really sticky, really retentive and that is, I think, the characteristic of the customer base that we have. So there's a lot of new information in today's report and presentation, it's a lot to get through, I know. But we felt that it was important in this are -- really our first opportunity to really talk about Ziff Davis going forward and how to think about the company. So I would encourage everyone to spend some time with the data that's in there.

And the next question is coming from Charlie Erlikh from Baird.
Charles Joseph Erlikh - Senior Research Associate
I just wanted to dig into the strong expected subscription growth in 2022. It's great to see that. Just love to get a little bit more detail on what's driving that? What are the key pieces there? And any color on that would be great.
Vivek R. Shah - CEO, President & Director
Yes. No, thank you. So it's a combination of real strength in the broadband business. So remember, the subscription business is roughly 60% the cybersecurity and martech subscription offerings. And then the balance is the connectivity subscriptions and the gaming subscriptions. So in that mix, the strength of the connectivity offerings is the primary organic driver of growth. Add to that expected organic growth within the martech offering, and that group is now called the Moz Group plus the acquisition timing benefit of Moz itself.
Remember, Moz was a mid-year 2021 acquisition. And so there is a timing benefit going into 2022. It is offset slightly by a cybersecurity suite that we are still scratching at looking for growth opportunities. It's a great business unit $200 million of revenue in cybersecurity, mid-30s EBITDA margin. But as I've talked about in the past, I wouldn't mind trading a little bit of that margin to accelerate the topline growth because I think the value of a more organically, though profitable, a highly profitable cybersecurity business, the value of that could be quite substantial, given just what the cybersecurity market looks like today. But the mix of those things, we're excited for that level of growth, and we see opportunities also within the Humble business that could be an addition to what we've modeled. So it is a good part and a good story as we look into this year.
Charles Joseph Erlikh - Senior Research Associate
Great. And if I can just squeeze one more in for Bret. You guys have talked about a 60% EBITDA free cash flow conversion rate in the past. Is that how we should be thinking about 2022 as well from a free cash flow standpoint? Because I think that might imply that free cash flow might be down year-over-year if that's the conversion rates. So any info on that would be awesome.
Bret Richter - CFO
Yes. Thanks, Charlie. Yes, free cash flow and free cash flow conversion continue to be a tremendous focus for the company, obviously, post the spin of Consensus and they have, to some degree, different margin dynamics than the overall company, those margins are going to change. I think, first and foremost, thinking about free cash flow is really a 12-month view. In any given quarter, you have sort of ups and downs. There could be working capital factors, timing of certain payments, our balance sheet and our interest expense and whatnot. Generally, we think about it in sort of a very holistic way, adjusted EBITDA, less our CapEx, interest taxes, the working capital will work itself out. Sometimes there's other sources and uses that are typically outflows to the company that we exceed for non-GAAP and all that plays in.
But we will continue to target the company towards about a 60% conversion rate of free cash flow, and we think that is healthy, overall, for a business like ours, producing significant amounts of after-tax, fully leveraged liquidity for us to pursue capital allocation alternatives. And yet, looking -- depending on the metric you use, and there's a tremendous amount of ins and outs with the company between dispositions, spin-off, the change in the balance sheet, not sure exactly which metric you're looking at, but we anticipate producing meaningful free cash flow to continue to fuel our strategy.
Vivek R. Shah - CEO, President & Director
And the only thing I'll point out is, remember, what you're looking at in the document, the historic free cash flows include the fax business. Consolidated -- discontinued and continuing up. So that would obviously indicate that the free cash flow of the continuing ops would be different.

And the next question is coming from Jon Tanwanteng from CJS Securities.
Jonathan E. Tanwanteng - MD
My first one is for Vivek. Do you expect to continue to see that pendulum swing towards you in the net spending this year? Or do you expect maybe some of the bigger players could cause some of that back as they adjust and adapt their business models for the new privacy and regulatory pressures that are out there. We saw Snap do that. I'm wondering if there's any possibility that the other bigger players could do that as well.
Vivek R. Shah - CEO, President & Director
I mean, look, there's always that possibility, and you can't underestimate the empires that exist in our world and their ability to try to manage through the challenges. But I -- look, I think that even prior to the IDFA changes, we had a lot of strength and momentum because I think our performance-driven solutions and the verticals we're in, aren't relying on a disabling of interest-based advertising. They compete well side by side.
So I would say that even if there is that response from the large platforms around some of their challenges. I don't think that changes our view, of our growth potential and where we're looking to go. And so no, I'm not concerned about that. I think more if the pendulum does swing our way, it's just more upside for us. But I don't view it as a threat because we've operated for a long time in an environment where we've had to sit side by side with very large hegemonic level players within the advertising ecosystem.
Jonathan E. Tanwanteng - MD
Got it. That's good color. Bret, just a question on the guidance. Can you talk about the EPS growth rate this year versus the EBITDA growth rate? Just why the discrepancy? I would normally expect EPS growth rate to be higher than EBITDA.
Bret Richter - CFO
Yes. I think, look, there's a couple of factors there. Again, we have to be very careful about our comparable periods and what we're looking at, given the changing dynamics of the company. Keep in mind that in the second half of this year, we converted the 3.25% converts, which increases our share count going forward. It only blends in, in the current period. We started -- we purchased some stock late in the fourth quarter and in the first that really doesn't factor into the fourth quarter.
So again, the measure that you're looking at. Our tax rate pro forma for the Consensus spin is going to go up. The Consensus business had a much higher concentration of international revenues and in venues of lower taxes and in some cases, some dip in tax dynamics and credits. So as we said in our guidance, we're going to see a little bit of a higher tax rate, but generally, the topline growth is going to feed the earnings machine and on a per share basis, it's -- that really may be dilution in tax dynamic are the 2 biggest contributors.
Jonathan E. Tanwanteng - MD
Okay. Great. And if I could sneak one more in there. Vivek, do you have the pipeline today to drive that earnings growth you're expecting to achieve over the next several years? Or is that something that you're still going to need to find the targets for. Just help us understand what you have in the pipeline against that goal of earnings.
Vivek R. Shah - CEO, President & Director
Listen, so step back, we -- our stated goal is to double earnings every 4 to 5 years. That's what we are looking to do, and we've done that 3 times in the last decade. So we're ahead of plan. And that combination is it's a combination of growing earnings from the portfolio we own and adding to our portfolio. So remember, this guidance, which from an earnings point of view, 13% at the midpoint, essentially gets us there, has no M&A from this point forward baked into the year. And as you can see on the schedule, in the slides, we had a fair amount of acquired revenue each year.
So I would say that -- I think I would look at it as the fact that we're growing this much without a lot of M&A activity in 2021 and without building in any into 2022 guidance puts us, I think, in a very enviable position for this year. Longer term, I would simply say that given the balance sheet we have and given the 10-year track record of putting our balance sheet to work, I remain confident in our ability to double earnings every 4 to 5 years.

And the next question is coming from Joe Goodwin from JMP Securities.
Joseph P. Goodwin - VP & Equity Research Analyst
Great. Can you just share what the assumptions are for organic growth within the guidance for 2022?
Vivek R. Shah - CEO, President & Director
It's about half of the revenue.
Joseph P. Goodwin - VP & Equity Research Analyst
Okay. So consistent with -- okay. And then I guess, could you -- can you describe maybe just what are some of the headwinds that you're seeing on the cybersecurity business today or the weaknesses that you're seeing like kind of what's going on there? And then you say you're looking at some of the different strategies. But I guess, what are some of those strategies that you're exploring?
Vivek R. Shah - CEO, President & Director
Yes. The biggest issue we've got there is how do you compete for customer acquisition in a very frothy environment where competitors have allowables higher than ours because they're willing to not generate profit. And so -- and we've run into this before. And I think we just have to be clever and crafty in the way in which we market. The customer acquisition LTV equation is very hard right now in the cybersecurity space. But to be clear, we have a very good franchise. It's just not a high-growth franchise and not a contributor to the overall organic growth of the company, right?
If you're not an organic grower, you are definitionally not contributing to the organic growth and it is a $200 million-ish revenue business. So we would like to return to growth. I think if I were to look in the portfolio, the area where we're seeing kind of the most challenges, specifically in the VPN space, it's a very competitive space, and they are -- we've got competitors who are prioritizing topline growth over profitability in, I think, non-sustainable way, that I think will -- as I've seen in many other markets, will, at some point, work itself out, but that's the environment win.
But it is a customer acquisition issue. There's certainly things we need to do on the product side that we're working on. That's a matter of time, ways in which we can improve our offerings and the user experience, but those are all in the pipeline, and I feel confident about that. It really comes down to how do we get the cap LTV equation right for the businesses.
