After management comments, we'll host a Q&A session with the financial community only. It is now my great pleasure to turn the call over to Oakleigh.
Thank you, Will, and thanks for joining us this morning. As we highlighted in our press release, Gogo's 2021 4th quarter marked an outstanding end to a transformative year for our company, our first full year as a pure-play business aviation connectivity leader. I'm incredibly proud of all that our team has accomplished and how well-positioned we are to create substantial value in the future. Let me start with a little highlight reel of key 2021 achievements that reflects the relentless focus and determination of our world-class Gogo team. Together, we met an intense surge in demand for BA connectivity equipment and data. In the midst of a global supply chain crisis, we scaled AVANCE shipments by 40%, and we successfully introduced business aviation's first unlimited data and streaming plan.
We hit historic financial inflection points, turning in positive quarterly net income and earnings per share for the first time in Q3 and positive free cash flow for the full year 2021. We completed a comprehensive refinancing that reduced our annualized interest expense by more than $70 million, giving us the financial strength to invest in improving our products and services, to further de-lever our balance sheet, to secure components in a supply-constrained world, and to return capital to shareholders when appropriate. We entered the exciting 200,000 aircraft-strong general aviation market with our Cirrus partnership, offering Gogo IFC on the G2+ Vision Jet. We gained traction in the under-penetrated light jet and turboprop markets, as evidenced by our recent announcement that the Pilatus fractional operator, PlaneSense, is installing our AVANCE L3 on their entire fleet of 46 PC-12s and PC-24s.
We executed extremely well on our Gogo 5G project, including most recently completing a test bed that sets Gogo up for an on-time, on-budget commercial launch in the 2nd half of 2022. We also signed up Jet Edge and Duncan Aviation to 5G commitments that will help secure a successful commercial launch. We continued our strategic initiative to drive penetration of our future-proof AVANCE platform with a 46% increase in installed base in 2021, and AVANCE now representing 39% of our ATG installed base, up from 30% at the end of 2020. We also achieved a 96% equipment retention rate for the year, which raised our rolling average equipment lifetime on an aircraft from 17 years to 18 years. Each quarter, we exceeded and then raised 2021 guidance, including exceeding Q4 expectations with the performance we announced today.
This is evidence of the very strong demand for IFC in the business aviation market and our superior performance in meeting that demand. As a reminder, we provided initial 2021 revenue and adjusted EBITDA guidance ranges of $300 million-$320 million and $105 million-$120 million respectively, significantly below the numbers we delivered today. We also introduced long-term financial targets on our year-end 2020 call, and we raised those targets again today, reflecting our bullish outlook on business aviation demand for in-flight connectivity and confidence in our continued ability to meet that demand. We've truly come into our own as a new Gogo, and our financial performance this year bears that out. We ended fiscal 2021 with record total revenue, driven by record AVANCE shipments and record service revenue.
We ended the year with 6,400 aircraft online, just short of 11% higher than at the end of 2020. We hit $3,300 in ARPU for Q4, up almost 8% from Q4 2020, and we grew full-year adjusted EBITDA 54% year-over-year. I'll focus my remarks this morning on the factors that drove our strong 4th quarter performance and that we believe will continue to drive our growth in the future. I'll share progress on our key strategic initiatives, and I'll introduce our 2022 financial guidance and updated long-term targets before turning it over to Barry. Then we'll open up the call for questions. It's evident from our 4th quarter that demand for BA travel and connectivity remains very strong.
We believe the two primary tailwinds driving that demand are the growth in high-net-worth individuals over the last decade and the significant increase in data consumption driven by growing usage of video-intense, social, and work-related applications, partly driven by the COVID pandemic. We also believe those tailwinds are sustainable, setting us up for long-term continued success as we execute on our strategy of enhancing our ATG network and driving market penetration of our AVANCE platform. Growth in the number of high-net-worth individuals over the past decade has driven significant growth in the cohort of people who can afford to fly privately, either on their own jets or through fractional shares or charters.
Not only has that cohort grown, but it's also grown younger, with 67% of the respondents in a recent Gogo brand study now from generations X, Y, and Z, and only 32% from my old Baby Boomer generation. COVID drove that cohort to try private aviation as an alternative to commercial airlines. Now that they've tried it, they're not going back. OEM sales of new jets and fleet sales of fractional ownerships are up dramatically, largely driven by new private flyers, indicating that those new flyers are making long-term financial commitments to private aviation. The 2nd tailwind, the dramatic increase in data consumption, is also driven partly by COVID.
The pandemic fundamentally changed the way that people of all ages think about connectivity as the work from anywhere and the socialize from anywhere cultures became the norm and drove demand for highly interactive, data-intense applications like Zoom, FaceTime, or Office 365. These two trends drove a 78% increase in the data consumed by business aircraft on our network in Q4 2021 versus pre-pandemic Q4 2019. The biggest variables driving that increase were a 38% increase in megabytes consumed per flight and a 29% increase in flights per day. The shift in data consumption drove 2.5 times as many customers to request plane upgrades as requested downgrades in 2021 versus a roughly even split between upgrades and downgrades in 2019.
We expect this growth in data consumption to continue driving ARPU as video-heavy content becomes more pervasive and ultimately as the metaverse and connected aircraft applications enter the aircraft cockpit and cabin. Fortunately, Gogo will have the capacity to meet this demand. Since offloading mainline commercial airline fleet several years ago, we have freed up a lot of capacity in our network and project that we could accommodate roughly triple the number of aircraft we have on our network today. We also expect the number of aircraft on our network to continue to grow, and that will drive the number of service plans we sell. We finished Q4 with 6,400 aircraft online, up 10.8% year-over-year, and we expect continued strong growth this year.
In Q4, we booked record new equipment orders, and our equipment order backlog already accounts for 90% of the 2022 equipment revenue in our guidance today. In fact, we see that trend continuing for the long term. Today, only 30% of the 24,000 business aircraft in North America have broadband in-flight connectivity. We expect that number to grow to 50% by the end of 2025, and a leading business aviation trade association projects that number to grow to almost 100% by 2035. Our bullishness on the business aviation market is buoyed by what we see in our OEM and dealer distribution channels. OEMs such as Textron, Bombardier, and Gulfstream are reporting the highest order flow in 15 years.
Since our AVANCE platform is installed on roughly 60% of the aircraft coming off the line destined for North American delivery, that is a very positive trend for Gogo. We're seeing even more demand in the dealer channel and are currently predicting a 50% increase in units shipped to dealers this year and projecting that dealers will represent more than 65% of our new shipments in 2022. Taken together, data, flight, and aircraft demand drove outstanding Q4 top-line growth for Gogo with record revenue of $92.3 million, up 19% year-over-year. We hit record service revenue of $69.3 million and very strong equipment revenue of $23 million. Our continued growth demonstrates the virtuous cycle of our business model in action.
Equipment sales profitably expand our base of subscribers, generating recurring, sticky, high-margin service revenue, which drives cash flow to invest in improving our network and platform, which in turn attracts new customers, driving more equipment shipments, generating more recurring, sticky, high-margin service revenue, et cetera. Finally, let me touch on our bottom line. Gogo's ability to translate the powerful demand tailwind I just described into bottom-line value is a testament to the exceptional unit economics of our business. Even excluding our huge Q4 income tax benefit, we delivered positive net income and positive EPS for the 2nd quarter in a row, both of which marked a nice contrast to the losses we ran in Q4 2020. We also more than doubled our quarterly adjusted EBITDA over Q4 2020, and we drove more than $50 million in free cash flow for the last half of the year.
We're proud of our results and the momentum we're building, and I'm proud of the Gogo team, which continues to rise to the challenge of meeting exceptional demand and executing on our strategic initiatives in a supply-constrained world. Now, let me turn to our strategic initiatives for a moment. Gogo has two major strategic initiatives aimed at deepening our competitive moat and driving long-term shareholder value. First, enhancing our ATG network to keep pace with customers' on-ground connectivity expectations, and 2nd, driving penetration of our flexible future-proof AVANCE platform. I'll start with enhancing our ATG network. The first step in the successful execution of that objective is the commercial launch of our Gogo 5G network in the 2nd half this year.
5G data speeds and low latency will be a top differentiator for Gogo as business customers increasingly require seamless video conferencing and VPN access, and leisure travelers expect living room quality streaming capabilities for accessing video-intense social media. We previously announced and continue to expect Gogo 5G to deliver 25 Mbps on average, with peak speeds in the 75-80 Mbps range, a significant improvement over the already competitive speeds AVANCE delivers today and leapfrogging both GEO-satellite competitors and a potential ATG competitor. As a reminder, our potential ATG competitor is still working toward a 4G network launch that they say will deliver speeds roughly equivalent to what we already deliver with AVANCE L5, and significantly slower than what we will deliver with Gogo 5G.
Even if all goes according to the potential competitor's plan, their eventual 4G solution will not be able to compete with Gogo 5G on speeds, not to mention many other product and service deficiencies that make a successful launch of their product highly improbable. As I'm sure most of you know, this potential competitor filed a lawsuit against us on Monday, alleging that our 5G implementation infringes on four of their patents. This from a company that has invested hundreds of millions of dollars over the past eight years and is now six years late on delivering a functioning nationwide network. Our patent attorneys and engineers have studied the entire SmartSky patent portfolio, and we know these four patents very well. I can assure you, we do not infringe on those patents, and we will fight this lawsuit with extreme vigor.
Now let me move to 5G advantages over geo-satellite competitors. First, they're limited to the super mid and heavy jet segments of the market because of the size and weight of their gimbaled antennas, and their equipment is more expensive and more difficult to install than ATG. But more importantly, we think 5G will outperform geo on speeds and on latency. Based on user customer surveys we've conducted, geo satellites provide speeds of 2-17 Mbps, depending on the provider, a bit slower than our 5G will offer. But more important, due to the 44,000-mile round trip that packets have to travel to reach the internet and then come back to the aircraft, they suffer very high latency, making interactive video difficult. While our ATG network is limited to the continental U.S. and Canada, geos have the advantage of near global coverage.
However, 87% of all global BA flight hours are in North America, and 77% are within the United States, which gives us a very large addressable market. In terms of 5G milestones, we've now passed all technical hurdles and are into the deployment and commercial launch phase of the 5G program. We reached a major deployment milestone at the end of last year when we completed a seven-tower test bed on time and on budget. The test bed includes sites in both remote and populated locations in order to validate that the network is operating as designed. We'll complete the other 143 towers at a rapid pace throughout the first half of 2022. Last week, we announced that the Gogo 5G aircraft antenna has received STC and parts manufacturer approval, or PMA, from the FAA.
Receipt of PMA is an important milestone as it essentially means that the FAA has green-lighted the mass production of our 5G radio antennas ahead of our 5G deployment. On the commercial side, we've already signed Jet Edge as Gogo's 5G launch customer. Jet Edge has AVANCE L5 installed across most of its large cabin fleet today. We'll upgrade 50 of those aircraft to Gogo 5G, which gives us a really strong head start on delivering our 5G projections. Additionally, Duncan Aviation, the largest independent MRO in the world, is upgrading all of its existing full equipment AVANCE L5 STCs to include Gogo 5G, which will cover more than 30 aircraft models, including aircraft manufactured by Bombardier, Gulfstream, Dassault, and Textron.
As Barry will touch on in a moment, 2022 is a big investment year as we deploy the 5G network, ramp up our sales and marketing, and fund inventory to support installation demand. It's worth noting that we expect to fund the entire 5G network out of internally generated cash flow. In fact, just one year of interest savings from our recent refinancing more than covers our entire 5G CapEx costs. Now let me move to our other major strategic initiative, AVANCE Penetration. AVANCE is a platform, not a product, that runs across multiple form factors and computing platforms and affords us tremendous opportunities to drive profitable growth by improving stickiness, introducing adjacent products, and penetrating adjacent markets.
AVANCE affords us many opportunities for growth, but for purposes of this conversation, one of the more important features of AVANCE is its multi-bearer capabilities, which allows us to add multiple networks to the aircraft in order to deliver more data capacity for passengers and crew. For instance, we could partner with a global LEO provider and add capacity from their LEO network to AVANCE's existing ATG capacity to deliver even more data to the aircraft. We could do that by simply developing an ESA antenna that sits on the fuselage of the plane and plugging that into the AVANCE platform inside the plane. That would be it from a hardware installation perspective. The rest of the install would be accomplished with an over-the-air software upgrade.
To make the math clear, let's say that in five years, we improve ATG to deliver 50 Mbps, and in that same time frame, LEO networks are deployed that can deliver 100 Mbps. If we added the LEO network to the existing AVANCE ATG installation, that configuration would deliver 150 Mbps, much greater than either the ATG or LEO network could deliver on their own. The global broadband initiative would allow us to, first, pursue the 14,000 business aircraft outside North America. Next, pursue geo-satellite installations on large North American jets that fly global missions. 3rd, defend and drive stickiness in our core North American market of medium-sized and smaller aircraft by offering LEO capacity if they need more capacity than what ATG alone can offer.
We think that we have some natural advantages over potential LEO competitors in pursuing the global LEO broadband initiative. First, our AVANCE installed base is several times larger than our competitors' install bases. It will be far cheaper for those aircraft to upgrade with Gogo and leverage the AVANCE system they already have in place than to rip out AVANCE and install new systems for all the functionality that AVANCE already provides. 2nd, our deep and mutually profitable distribution channel relationships with OEMs and dealers. We're already line fit in all business aircraft, and we have our 120 dealer network already outfitted to install AVANCE. Adding an ESA to their installations would be relatively simple compared to cutting in a whole new product. 3rd, speed to market.
We can simply amend the OEM type certificates and aftermarket supplemental type certificates that already exist for AVANCE to add the ESA antenna, just like we're doing now for 5G, giving us a speed to market advantage over competitors who will be starting from scratch. In short, we see tremendous upside of the LEO strategy via AVANCE. If we proceed, we expect to accelerate our growth in the latter half of this decade, and we expect our investment would be modest compared to our 5G investment, and it would be spread over several years. Another way AVANCE gives us opportunity to grow is the ability to remix common componentry into new form factors while using the same AVANCE software to address the specific needs of adjacent markets. Our entry into the general aviation market is a good example.
We accomplished this by developing the small form factor of AVANCE L3 and by lowering our service floor to 3,000 feet with a software upgrade, not an equipment upgrade. With those changes, we've gained traction both in the smaller fuselage segments of the business aviation market and in the 200,000-strong general aviation market. Two markets where our competitors' equipment is too large to compete. The beauty of it is that with the same software and using common AVANCE componentry, we can continue to develop new form factors that will further help us penetrate those markets. To summarize, AVANCE gives us a lot of opportunities to improve equipment stickiness, introducing adjacent products, and growing into adjacent markets. For those reasons, growing the AVANCE install base is core to our strategy. So far, we've been quite successful at that.
AVANCE is the most successful broadband product ever launched in business aviation, with just over 2,500 aircraft online at year-end 2021, up 46% over prior year. It's installed on more aircraft than our two biggest competitors combined. We reported 105 net AVANCE installs in the month of December alone and 267 for the quarter. We project at least 25% growth in AVANCE unit shipments this year. As I already mentioned, we've already booked 90% of those orders. We also see demand drivers that lead us to believe we can exceed our 25% unit growth target and are intensely focused on our supply chain to see if we can make that happen.
Now I'll touch briefly on our financial guidance before turning the call over to Barry, beginning with a few caveats. First, our 2022 guidance does not include potential strategic investments like the LEO global broadband product I discussed a moment ago. Assuming we green-light those initiatives, we'll roll those into our projections and update guidance as appropriate. 2nd, we've long characterized 2022 as an investment year, focused on finishing our 5G deployment and supporting its launch with all the resources necessary to succeed. That said, we expect to still grow adjusted EBITDA and still have positive free cash flow despite those investments. We're also extending and raising our long-term financial targets driven by the strong equipment sales we're seeing today and the usage trends I highlighted earlier in the call, both of which will drive sticky, high-margin, recurring service revenue for many years to come.
In turn, those new financial targets are the springboard for our capital allocation strategy, which Barry will walk you through in a minute. We have our 5G investment well in hand, and we zeroed in on our target leverage ratio. As soon as we complete sizing our strategic growth opportunities, we can vector in on our approach to returning capital to shareholders. Let me conclude by saying we believe Gogo presents a unique and compelling opportunity. We serve an under-penetrated market that should provide opportunity for years of profitable growth. We differentiate ourselves based on our deep understanding of that market and our ability to create unique services and products tailored to the specific needs of that market.
On top of that, we see numerous opportunities to deploy modest amounts of capital into adjacent products and into adjacent markets to accelerate profitable growth in the latter half of the decade. We're excited about the future and Gogo's ability to deliver for our customers, employees, and shareholders as we execute on that strategy for long-term value creation. Now I'll turn it over to Barry.
Thanks, Oak, and good morning, everyone. We're pleased to have capped off a very strong 2021 by continuing to set new records in the 4th quarter. Our 2022 financial guidance and the increased long-term targets we announced this morning underscore our confidence in the significant value creation opportunity ahead. Before we talk about our expectations in more detail, I'll walk through our 4th quarter results, starting with the top line. Total revenue for the 4th quarter was $92.3 million, increasing 19% year-over-year and 6% sequentially, fueled by strong growth in both service and equipment revenue as demand continued to exceed our expectations. Gogo's top-line growth is a reflection of the accelerating strength of the business aviation market and Gogo's unique ability to capitalize on that growing demand.
Our record service revenue of $69.3 million in the 4th quarter represents an increase of 22% year-over-year, driven mainly by more AVANCE units coming online and stronger ARPU. On a sequential basis, our 4th quarter service revenue grew 5%. ATG aircraft online reached record levels of 6,400, up 11% compared to the 4th quarter of last year and 4% sequentially. As Oak highlighted, AOL growth, accompanied by our subscription-based service revenue, is the biggest driver of our long-term value creation, as we are fortunate to operate in an under-penetrated BA market with significant headroom for continued growth. New customer activations represented 66% of our total activations during the quarter, the strongest ratio in two years.
As further demonstration of the strength of the demand for connectivity, data usage continues to grow along with aircraft online, growing 78% in the 4th quarter of 2021 over the pre-pandemic levels in the 4th quarter of 2019. ARPU grew to $3,301, representing an increase of 8% year-over-year and 1% sequentially. As Oak mentioned, demand for data by passengers as well as our unlimited streaming plan and other innovative new products we've introduced contributed to this continued ARPU expansion. Turning now to equipment revenue. Gogo delivered very strong equipment revenue of $23 million for the 4th quarter, an 11% increase year-over-year and a 10% increase sequentially, reflecting strong demand for both our AVANCE L3 and L5 products.
We had a record 285 AVANCE product shipments in the 4th quarter, representing 10% growth year-over-year and 8% growth sequentially, with increases in both the aftermarket and OEM channels. I wanna highlight that our 887 total AVANCE shipments in fiscal 2021 represents 40% year-over-year growth. These strong results are based on the robust market demand, which began in late 2020 and increased throughout 2021, ultimately exceeding our original 2021 internal budget by 30%. We exited 2020 by posting an outstanding 4th quarter through a combination of typical seasonal strength, promotional activity, and the beginning of business aviation's recovery from the effects of the pandemic. The confluence of these factors somewhat masked the fundamental demand-driving shifts that solidified and accelerated during 2021 to drive unprecedented demand for Gogo equipment.
Looking to 2022, we are experiencing continued strength in AVANCE shipments and now expect growth at or above the high end of our previous expectations of 20%-25% growth over 2021 levels. We exit the 4th quarter of 2021 with a very strong order backlog, representing again 90% of our expected equipment shipments for 2022. This backlog meaningfully de-risks the achievement of the targets we communicated this morning. I'll provide more color on our guidance later in my remarks. Now turning to profitability, Gogo delivered service margins of 80% in the 4th quarter, ahead of our expectations, largely due to lower than anticipated network costs. Excluding the impact of the regulatory surcharge credit that bolstered our 3rd quarter service margins, our service margins increased 250 basis points sequentially.
We expect our long-term service margins to trend to the high 70% range throughout our five-year planning horizon. On the equipment side, Gogo delivered equipment margins of 37% in the 4th quarter, a 400 basis point sequential decrease. This decrease is in line with the expectations we set on previous calls for declining equipment margins in the near and intermediate term as we pursue our strategic objective of increasing AVANCE penetration, which Oak has discussed in some detail. In alignment with this objective, we anticipate equipment margins to be lower for 2022 than they were for 2021. Importantly, from a financial perspective, AVANCE equipment sales are the foundation for high-margin recurring service revenue, which in turn is the engine of our future value creation.
Moving to operating expenses, 4th quarter combined engineering, design and development, sales and marketing, and general and administrative expenses excluding depreciation and amortization of $28 million decreased 8% year-over-year. This decrease reflected the increased employee bonus expense recorded in Q4 2020 as we made the decision to shift the form of the annual bonus payment from stock-based compensation to cash. Now I'll provide some additional detail on our Gogo 5G program and spending profile. I'll start by saying we are on track to deploy our network in the 2nd half of 2022 on time and on budget. As planned, our 5G spend increased in the 4th quarter to $4.6 million, comprised of $1.7 million in OpEx and $2.9 million in CapEx.
I'll note that our GAAP 5G CapEx spend came in lower than we expected for this quarter due to a lag in the timing of $4 million in invoices that will be paid and reported in the 1st quarter of 2022. To be clear, the timing of this reported spend is not indicative of a slowdown in our deployment schedule. For 2022, we have budgeted external development and deployment OpEx of $11 million, an increase of $7 million over 2021, and additional Gogo 5G related investments in marketing, production operations, and network costs of $6 million. This results in an approximately $13 million increase in total OpEx related to 5G in 2022 versus 2021, and of course impacts the adjusted EBITDA growth rate for 2022.
To reiterate our overall expectations for CapEx, we expect that over 90% of our total Gogo 5G investment will be completed by the end of 2022. We expect 2022 CapEx to be approximately $65 million, with approximately $50 million of the spend tied to Gogo 5G. After Gogo 5G is launched, we continue to expect ongoing capital expenditures in the $15 million-$20 million range annually, supporting very attractive adjusted EBITDA to free cash flow conversion rates in 2023 and beyond. Now on to our bottom line. As expected, our adjusted EBITDA was slightly lower in the 4th quarter at $39.6 million, down 3% sequentially due to the one-time regulatory surcharge credit in Q3 and higher operating expenses in the 4th quarter as anticipated.
On a year-over-year basis, quarterly adjusted EBITDA more than doubled, driven by significantly higher profit from our subscription-based service revenue as we have grown AOL nearly 11% year- over- year. Last year's 4th quarter also included the higher bonus expense I described. As we mentioned earlier, Gogo generated positive net income from continuing operations for the second consecutive quarter. Our reported net income includes an income tax benefit of $188 million in the 4th quarter due to the partial release of the valuation allowance on our deferred tax assets. Based on our expectations for continuing strong operating performance, additional reversals of a remaining valuation allowance of $111 million may occur within the next 12 to 18 months.
Importantly, even excluding the impact of the valuation allowance, Gogo delivered positive net income from continuing operations of $21.5 million in the 4th quarter. This translates to basic earnings per share from continuing operations of $0.18 and diluted earnings per share of $0.17. As of December 31st, 2021, Gogo had $689 million in federal net operating losses. With our substantial NOL position, we do not expect to pay meaningful cash taxes for an extended period of time, though we may pay some cash taxes by the end of our planning horizon. For the 4th quarter, Gogo generated record free cash flow of $25.7 million, reflecting our strong top line and adjusted EBITDA performance.
This also includes the impact of the comprehensive refinancing we completed in April, which materially reduced our annual interest expense and enhances our strategic and financial flexibility. While we expect some shifts quarter to quarter, for example, due to the timing of our 5G expenditures, our expectation is to deliver positive annual free cash flow going forward. As you know, we substantially increased expectations for free cash flow in 2023 and 2025 on our 3rd quarter call. As I'll talk about in a moment, we continue to expect a very significant ramp in free cash flow beginning in 2023. Before I move to a discussion of Gogo's capital allocation priorities and our balance sheet position, I'll briefly summarize our full year 2021 fiscal year results.
We achieved significant top line growth due to strong tailwinds driving the business aviation market, which by all indications are sustaining, coupled with solid execution. Gogo generated total revenue of $335.7 million, up 24% from 2020, and well above the high end of our guidance range. We delivered service revenue of $259.6 million, up 22% from 2020, with service gross profit also growing 22%, a key contributor to our significant free cash flow growth. Equipment revenue was $76.1 million for the full year, up 32% from 2020, well above our expectations, as I mentioned. For the full year 2021, we achieved adjusted EBITDA of $151 million, a 54% year-over-year increase, and also significantly ahead of our 2021 guidance.
Free cash flow of $58 million was well ahead of the more than $40 million expectation we set for the full year on our November 21st earnings call. All in, 2021 was a remarkable year. The strength of the business aviation market, customers increasing demands for connectivity, and Gogo's robust business model as a pure play business aviation company all contributed to this outsized performance. We believe this positions us well for significant future value creation. Now let's turn to a discussion of our balance sheet. Gogo is in a very strong liquidity position. We exited 2021 with a cash balance of $145.9 million, and our $100 million revolver remains undrawn.
At the end of the 4th quarter, we had approximately $824 million in outstanding debt, including the $721.4 million term loan B, and approximately $103 million in outstanding convertible notes. Based on our strong financial performance in 2021, we exited the year with a net leverage ratio at 4.5 times adjusted EBITDA. Notably, this is down from a net leverage ratio well into double digits four years ago. We're tremendously proud of the progress Gogo has made on our debt reduction goals. The sale of our CA business on December 1, 2020, and the comprehensive refinancing completed in April 2021, have enabled us to reduce our debt by nearly one-3rd from the 2020 levels. As a result of our progress, Gogo's balance sheet is now a competitive strength.
As we mentioned on our 2nd and 3rd quarter earnings calls, Gogo committed approximately $10 million in cash for additional inventory purchases during 2022 to ensure we can deliver on equipment orders that already stretch well into 2022. Looking ahead, as previously announced, we expect to settle any conversions of the $103 million of convertible notes in stock prior to their maturity on May 15. Given our current stock price relative to the $6 conversion price, we expect all holders of the remaining converts to elect to convert into a total of approximately 17.1 million shares. As a result of our comprehensive refinancing plan, our annualized cash interest expense will have been reduced from $111 million before our April 2021 refinancing to approximately $33 million after the convertible notes mature in May of this year.
Our strong balance sheet and operating performance provide us with significant strategic and financial flexibility. On previous calls, we indicated that we would pursue a balanced capital allocation strategy focused on four primary actions in the following order of priority. First is enhancing the capacity and performance of our ATG network through the deployment of 5G. Second is reducing overall leverage to an appropriate operating level. Thirdly is making strategic investments in our business, such as the global broadband initiative, to capitalize on market opportunities and further strengthen our competitive position. Finally, returning capital to shareholders. We made considerable progress on the first two of these actions with Gogo 5G on track and deleveraging ahead of schedule, driven by our strong financial results. We're now actively addressing the latter two priorities. With respect to value-enhancing strategic investments, as Oak discussed, Gogo is seriously evaluating a LEO-based global broadband initiative.
This would increase the number of planes in our available served market and further defend our strong market position in North America. While we are also exploring other strategic investments, we would only execute on any of these if they are meaningfully value-enhancing to our business. With respect to our fourth priority, the timing and amount of a potential return of capital will be informed by our capital structure strategy. Our targeted capital structure includes maintaining minimum available liquidity of $125 million, with the majority of this liquidity comprised of cash, but also considering our revolver capacity. Secondly, a targeted net leverage ratio of less than 4x. We expect to achieve this net leverage target in the 2nd quarter of 2022 after the expected equitization of our convertible notes in May.
Given our strong cash position and the additional dilution from the expected equitization of our convertible notes, our board is evaluating capital allocation strategies that may include share repurchases. Let me add one final housekeeping point related to our capital structure. You may remember that when GTCR exchanged its convertible notes for common stock last April, we entered into a registration rights agreement that gives GTCR customary demand and piggyback rights with respect to shares held by GTCR and its affiliates. The registration rights agreement, as amended, requires the company to have a shelf registration statement declared effective by May 23, 2022. Now I'll turn to the guidance we announced this morning, starting with some color on our 2022 projections. We continue to expect significant top-line growth.
At the end of September, we said we expected growth in AVANCE shipments of at least 25% in 2022, and that was on top of the strong 2021 performance we've outlined. I'll iterate that 90% of the equipment revenue included in our 2022 top-line guidance is already in our backlog, which meaningfully de-risks our 2022 revenue plan. In spite of our expectations for strong top-line growth, we view 2022 as an investment year, particularly for Gogo 5G, and we wanna be clear that we don't expect our bottom line to grow at the pace we delivered in 2021. Our priority is to deploy our 5G network and support its successful launch with healthy sales and marketing investments. We also anticipate higher working capital needs as we meet higher demand for AVANCE unit shipments.
Our wider free cash flow range reflects potential additional spending to secure inventory to support that demand. We expect our EBITDA to be weighted toward the 2nd half of 2022, which will set the table for a substantial increase in EBITDA, and particularly free cash flow growth in 2023. Turning to the numbers, we announced the following 2022 guidance in our press release this morning. We expect 2022 revenue in the range of $380 million-$395 million, reflecting double-digit service and equipment revenue growth. We anticipate 2022 adjusted EBITDA in the range of $150 million-$160 million, reflecting a planned increase in Gogo 5G investment, as previously discussed.
We expect free cash flow of $25 million-$45 million, including cash interest payments of approximately $36 million and capital expenditures of approximately $65 million, with approximately $50 million of the CapEx spend tied to Gogo 5G. The 2022 guidance and long-term targets are derived from our baseline budget and recently updated baseline long-term model, which include Gogo 5G but do not include potential strategic investments currently under consideration, including a global broadband initiative. The 2022 adjusted EBITDA and free cash flow guidance and long-term targets do include a preliminary estimate of the defense cost for the SmartSky Networks lawsuit filed against Gogo this week. Now turning to our long-term targets. We are updating our baseline long-term targets as follows. Revenue growth at a compound annual growth rate of approximately 15% from 2021 through 2026.
It's worth noting that we expect to be able to maintain this 15% CAGR target for an additional year in spite of dropping 2021, which represented 24% growth over 2020 as the initial year. Annual adjusted EBITDA margin approaching 50% in 2026, up from the low 40s in 2022 and 2023. Free cash flow of approximately $125 million in 2023, following the deployment of the Gogo 5G network in 2022, increasing to over $200 million beginning in 2025. Before we open the call up to questions, I'd like to reiterate our thanks to the entire Gogo team for the outstanding performance this quarter and throughout 2021. Our results are a testimony to your dedication, ingenuity, and unwavering focus on delivering for our customers and reaching our strategic goals. Thank you, team. Operator, this concludes our prepared remarks. We're now ready for our first question.
Ladies and gentlemen, if you have a question at this time, please press the star and then the number one key on your touch-tone telephone. If your question has been answered or you wish to remove yourself from the queue, please press the pound key. Your first question comes from the line of Phil Cusick with JPMorgan. Your line is open. You may now ask your question.
Hi, this is Amir for Phil. Any update on supply chain for getting the ATG units this year? At what level of growth might you hit some issues? Beyond that, for the expected revenue growth for 2022, can you break out your expectations for equipment versus service revenue growth?
Why don't I take the supply chain piece, and Barry can take the breakout on growth. You know, managing supply chain is very tricky these days, as I'm sure you're aware. We have secured supply with you know, guarantees, et cetera, to meet our equipment budget and the 25% unit growth that we forecast. We are very busy trying to secure more supply, and I think we've made substantial progress on that. We have sort of two tiers. We have sort of the natural well, I'll say an increase in demand that we see out there that we'd like to meet, which is one level of target, and I think we're getting very close to being able to say that we've nailed that down.
Probably have more guidance on that later in the year. Then we have more of a stretch goal for the second half that, you know, we're still working hard on trying to secure. It's challenging world, but, you know, our balance sheet's helping us out in that we can come in and prepay where we need to. We also, I would say that our common componentry strategy, where, you know, L3, L5 and future form factors, you know, use the same components. They use them in different mixes and different configurations, but they're the same components. That gives us the ability to have more, you know, bigger orders and have more sway with our suppliers. Both those things are helping us out right now. You know, we're optimistic, but we're not to the point where we're gonna be raising equipment guidance.
Amir, on your question about the breakdown, you know, we aren't providing details on that. I would just say that, we are, as you see, of course, setting expectations for a 15% CAGR over the full planning horizon. Based on the guidance that we're giving for revenue in 2022, you can see that we expect to get out of the gate strongly, in that area. Again, we expect to have strong growth in both service revenue and equipment, with expect probably in percentage terms, equipment revenue to growing a little bit, more strongly in terms of the higher rate than service revenue because of the demand that we're seeing.
Thank you, guys. One more, if I may. On the CapEx spend in 2022, how should we be thinking about the cadence of that? Does some of that CapEx for 5G roll over into 2023? Thank you.
Yeah. The CapEx spend, as you know, is largely tied to the tower builds in 2022. That CapEx spend is going to be primarily over the first three quarters, but will be spread throughout the year. It'll be loaded in that first three-quarter time period, would be our expectation. There will be some CapEx for 5G continuing into 2023, but 90% of the CapEx spend will be completed by the end of 2022 is our expectation.
Thank you, guys. Congrats on the quarter.
Thanks, Amir.
Thank you.
Thanks, Amir.
Your next question comes from the line of Scott Searle with Roth Capital. Your line's open. You may now ask your question.
Hey, good morning. Thanks for taking my questions. Nice job on the quarter, guys. Hey, maybe just quickly to jump into the service provider revenue and guidance for 2022. I'm wondering, how are you seeing ARPU trend given the uptake of AVANCE, given the pending 5G launch? Also starting to see GA contribution, which I assume comes in at lower ARPUs. Then I had a follow-up.
Yeah, Scott, I mean, I think we've guided to sort of 3%-4% ARPU growth over time in the five-year guidance. You know, we kind of blew that away this year because we had a you know a lot of upward pressure on ARPU from our streaming, unlimited streaming and data plan. I think that you know we still continue to see ARPU, and Barry can give you the exact number, but in the 3%-4% growth range for the five-year model, and I think that's you know kind of what we would guide to this year.
Gotcha.
Yeah.
Great.
That's, Scott, over time, it's basically 13% driven by AOL growth, and 3% is ARPU growth over the horizon from 2021-2026.
Very helpful.
Scott, like
Oh.
Scott, sorry. As like you point out, I mean, we've got upward pressure, you know, at the high end of the market that wants these big unlimited plans. Then as we make more progress in the general aviation market and in the, you know, the light jet market, you know, those people tend to buy lower rate plans, so there's downward pressure as well. That's all good for us. I mean, that's all, you know, in absolute terms, that's all growth.
Then, oh, maybe if I could to dive into the 15% CAGR through 2026. It's a big number. It's a step up from what you guys have been talking about before. Certainly, there are strong demand characteristics in terms of under-penetration in the marketplace. But I'm wondering, you know, why your comfort level is so strong at this current time. A couple of items and clarifications. What are you thinking about in there in terms of GA contribution? It sounds like LEO contribution or potential LEO contribution really isn't built into that. That comes in the back half of the decade. Maybe if I could throw on top of that, too. The LEO, potential LEO investment. I'm not sure if I've heard you size the magnitude of what that would require. Thanks.
Yeah, sure. Scott, let's break that question down into a couple pieces. I'm sorry, you started with?
Oh, well, the 15% CAGR, really the
Oh.
The confidence level now, by now, and what are you factoring into that?
Yeah, sorry. Thank you. Yeah, the great thing about that number, frankly, is that, you know, we lost a really high growth year of 24% at the beginning. You know, the recovery from COVID, we had tremendously strong growth. That came out of the model, and we added another year at the end. Being able to hang in at that 15% CAGR, we thought it was really good. You know, in terms of projections, you know, we sort of built these models from the bottom up, and we're looking at demand in various segments of the market and how it flows through the distribution channels. You know, we're pretty confident in those.
You know, a lot of like right now, you know, a lot of this growth, we're already booking orders for 2023. You know, we have you know, pretty good visibility as we look ahead at least over the next couple of years. When you look at the unpenetrated market and the fact that we're getting traction in some of the less penetrated parts of the market, you know, we're very confident in these numbers barring you know, a massive global recession or this you know, unfortunate war blowing up on us and you know, causing some macro events that come in and impinge on us. We feel good about that. In terms of the GA, what we have in the model now are sort of our current GA commitments.
We've got a few other things going that we've factored in that we think are fairly high probability. It's not a big number, frankly, but there is some GA included in there. LEO is not in. You know, in our vernacular, we call that an overlay. Right now it's sitting as a long-term financial model that we haven't laid into our long-term projections. When we greenlight it, then we will roll it in.
We haven't really sized it other than to say it's, you know, relatively modest compared to our 5G investment, and I think you know what our 5G investment is. Also, the LEO investment would be spread out, would be peanut buttered a little more than the 5G investment is. Most of the 5G investments this year, the LEO investment would be, you know, it's gonna take a couple of years of development and so it's moved over two, three years.
Perfect. Thanks. Nice quarter, guys.
You bet. Thanks, Scott.
Thanks.
Your next question would be coming from the line of Lance Vitanza with Cowen. Your line's open.
Thanks, guys. Thanks for taking the questions. I had two. The first is on the long-term financial targets, the meaningful increase in your targeted EBITDA margin. I'm wondering if you could discuss the factors that are leading to your more encouraging outlook there. In particular, as part of that, how does competition, potential competition figure into that longer-term target? In particular, if we're all wrong and SmartSky Networks does get its act together, should we expect that would negatively impact your margin target? Thanks.
I'll touch on the beginning. I'll touch on the end, and then, Barry, why don't you take the beginning of the question. In terms of our long-term model, we do factor in competition. You know, we project continuing positive trends for our GEO competitors in the segments of the market they address or are starting to address. From a SmartSky Networks, you know, we have included them in our projections. You know, we don't project them having tremendous success, but you know, in order to be conservative, we've assumed that they actually launch at some point and you know, win some portion of the aircraft. You know, as we watch them, as we learn more about them, and we do deep analysis, you know, we think the odds of success are very low there, to be honest. you know, we still have them in our models.
Yeah. Lance, to your question about EBITDA margins and why we see those going up, there are a couple of drivers of that. In the next couple of years, we do expect to have lower equipment margins as we invest in the penetration of the AVANCE platform, as we've talked about. That's a very conscious effort to use that to drive service revenue. What's really driving the expanding margin over time is the growth in the service revenue combined with operating leverage.
When you look at, you know, OpEx as a percentage of revenue over time, we expect that to come down meaningfully. We're seeing that as we drive the kind of G&A reductions that we've talked about for a couple of years, and we're seeing that happen. Really is a combination of the mix of strong service revenue and operating leverage without having to increase the OpEx at the same rate as the revenues are growing over time.
Thanks. Just lastly for me, you know, Oak, you gave your assurances that Gogo has not infringed on the four patents that are identified in that current SmartSky Networks lawsuit. Can you offer assurances that Gogo hasn't infringed on any of their other patents as well?
Yeah. Our lawyers and engineers have reviewed all of their patents, and we do not infringe on any valid patent of theirs, and we've stated that before. I'm not gonna get into talking about these four in particular, just because from a litigation perspective, we don't wanna, you know, tip our hand in any way to them, and they, you know, they do listen to these calls. I'll refrain from, you know, talking about the four in particular.
Thanks, guys.
Your last question. Oh, I'm sorry. Your next question comes from the line of Ric Prentiss with Raymond James. Your line's open.
Thanks. Good morning, everyone.
Hey, Ric.
A couple of questions I wanna follow up. Obviously, supply chain is the key item in a lot of industries. Sounds like you're gonna try and get some more supply. How should we think about dollar-wise? Last year, you, I think, spent about $10 million to get in this kinda pre-purchase stuff. How should we think about magnitude of what you're trying to put to work this year to make sure you've got supply?
Yeah, I wouldn't.
Yeah, Rick, the $10 million we didn't spend all that last year. The $10 million is the amount that we're looking to spend this year. We have identified the needs for, you know, a meaningful portion of that, but not all of it. We'll use that to drive it. In combination with the other things we're doing, Rick, you know, a number of things we're doing, running our MRP program with a much longer horizon, 18-24 months, and have. That shows the demand that we can then place orders on, so we can get on better allocation. We have designed the products with alternative parts that we can get so that we're not completely reliant on sole source parts.
We've actually helped some of our suppliers source parts when they have not been able to do that. We're doing a number of things to really drive that supply chain success. As we mentioned, we feel good about being able to deliver on the expectations for equipment that we've set on this call, but we think the demand could drive higher opportunity there. That's really the piece we're working on now is how do we increase the supply chain capacity to deliver on those potentially higher opportunities.
Makes sense. Another hot topic is inflation. How are you guys looking at inflation? How is it affecting your business?
Yeah. We have some inflation built into our plans. We have, you know, wage inflation built in. We have cost inflation on our materials. We have that built into our plans. Interestingly, you know, a meaningful portion of our cost structure is not generally tied to inflationary trends. Like backhaul and the network operations, and we've seen actually some declines in that over time as backhaul costs get more aggressive. When you combine that with high gross margins, you know, it's not like being in the grocery store business. With the high gross margins, we're, you know, a little less vulnerable to that than we would otherwise be, but it's certainly something that we're mindful of.
Last one for me is over the months of November, December to January, the phrase 5G started taking on a very different connotation to consumers. The press and the FAA going out there kind of scaring people about what could happen with air travel with the C-band, but they didn't actually call it C-band. They were calling it 5G. What have you heard from your OEMs or dealers and end users about 5G? Are they concerned about what 5G means? Are they concerned about anything with aviation related that way, either affecting your sales or just impacting concept of what 5G means?
Yeah. I think we communicated well with our distribution channels. I think they all understand the difference between the C-band and the spectrum we're operating in, and frankly, understand that the media kinda confused C-band and 5G. 5G, as you know, uses lots of different spectrum. The spectrum we use isn't anywhere close to the spectrum that was in question. We haven't seen any impact on our sales as a result of that.
That's great 'cause obviously it caused a lot of concern. I said even just inside my own household, people are going, "Can we fly?" It's like, "Yes, you can.
Well, most of that has been cleared up. The FAA has cleared, you know, most of the altimeters in question, so.
Yeah. Good to hear it's not affecting demand or concerns. All right. Thanks, guys. Stay well.
Thank you.
Your next question comes from the line of Landon Park with Morgan Stanley. Your line's open.
Thank you. Good morning, everyone.
Hey, Landon.
I was wondering if you guys. I think last quarter, you guys said that your backlog lead time had stretched all the way out to, like, six months. I think you referenced earlier that you're already taking orders for 2023. Where is that lead time at now versus last quarter? Just any thoughts there on when that might start to normalize?
Well, we're very creative in terms of how we manage lead time, and we don't wanna miss an install if we have the opportunity to get it. You have to understand, in our market, you know, jets come in for their maintenance in a scheduled manner. You know, the MROs and dealers would have their floors booked up now pretty well, you know, for the year, and we've been able to meet that demand so far. That's good. Look, if somebody came in and needed a box in three months, I'm sure we'd figure out a way to get it to them. You know, we are, you know, technically we're booked into the 4th quarter now, but we never wanna miss an order.
Okay.
The 2023 orders we've got aren't because of lead time. That's just because of the MROs, you know, buying equipment for a specific maintenance event that's gonna happen in 2023, not in 2022. Most of the-
Great.
Most of the stuff we've shipped is, and when it goes to dealers, most of what we ship is booked for a particular customer already.
Great. Thanks for that color. On the capital returns, I think you guys referenced the 4x of that. I think that was a 2Q number. Is that also the long-term level that you're comfortable with, when you're considering buybacks or dividends? Or how are you thinking about where that long-term leverage should settle out?
Yeah, we think about it in two phases, Landon. The first is that we want to get to a net leverage ratio of less than four times. That will kind of be the threshold at which we start to really think about when we might consider returning to capital, what that timing might be. As we've discussed, we need to make sure that we finish sizing the strategic investments to inform that decision. Getting to less than four times is the initial target. Then what we would run the company with beyond that is a you know something that we will look at more carefully as we hit that ratio and see what the right level of the debt is on an ongoing basis. For now, you know, we've put a stake in the ground less than four times.
Okay. Great. Then just the last one from me. On the lawsuit, the preliminary injunction, do you have an expected timeline on when you think that matter could at least be settled?
No. I mean, frankly, this is news that is relatively new. We did anticipate this happening at some point. Frankly, we probably thought it would happen a little closer to our 5G launch than it is. You know, we have actually not even received papers yet, but you know, we factored this into our budget. We have some money already set aside for defense. You know, I think any guidance on timing now would be premature.
Okay, great. Thanks very much.
Thank you, Landon.
Is the last question Louis? Yeah.
Your last question comes from the line of Louis DiPalma with William Blair. Your line's open.
Great. Thanks, Oak, Barry, and Will, good morning. For Barry, can you please repeat the comments that you said about the potential share buyback? Just because it seems to be a pretty significant contrast, you know, relative to Gogo's history in which I think you previously alluded to how you had 10x leverage, and you used to be burning $100 million or more in cash on a quarterly basis. What are the different stages and thresholds in terms of leverage and timeline associated with 5G and the LEO Broadband initiative that investors should consider as you and your board of directors evaluates a potential share buyback? Thanks.
Yeah, we're in a very different place, Louis, than we were from the time we first started having these conversations with you, as you know. It's a privileged position to be in and to be able to even think about these things. What we said is that we expect to achieve this net leverage target in the 2nd quarter of 2022 after the equitization of the convertible notes in May and that given the cash position and that dilution from the equitization, our board's evaluating capital allocation strategies that may include share repurchases.
It's something that we are looking at. Kind of the things that inform that will be the amount and timing of the strategic investments in things like global broadband. We wanna make sure we're conservative about those and have ample dry powder for those. But having said that, you know, we are in a strong cash position now, and it's something that we are kind of evaluating in terms of what the right time might be, in this context. We're in a privileged position, I guess, at this stage.
Thanks, Barry. For Oak, I was wondering, what is the development status of LEO satellite antennas for business aviation? Are there any antennas available now that you are currently trialing on aircraft, or are there any available for other service providers, or are these antennas still in the development stages?
In the development stages, Louis. I mean, there's a lot of debate around antennas that will access LEO constellations. We think the best technology is an electronically steerable antenna. You know, we are in the process of talking to providers that we would work with in developing one. You know, we're not gonna give away our secret sauce in terms of what we think about design on this call. You know, we know the BA market very well, and our goal is to design something that is very particular to that market and will fit that market. In terms of ESAs for aviation, I mean, they've been used in the military for quite a long time.
They're very, very expensive in the military. They are in development for commercial aviation now, and there are some that I think are in an experimental status at this point and have been put on jets and flown. But those are much larger, frankly, than what would fit on a business aviation aircraft. The trick is, the smaller the antenna, the lower the power. As the power goes down, the harder it is to maintain the link budget with the satellite.
Right
That's why it's been the challenge in business aviation. It's a matter of being able to get enough power and have it work without creating too much heat in the aircraft and burning a hole in the fuselage, and get enough power that you've got a good signal and a good product. That's difficult. You know, but we're working on it, and you know, we are optimistic.
One final question. Oak, do you have any estimate for how many days would it take an MRO to install the 5G antenna for a customer that already has the AVANCE L5 system, and how complicated would that upgrade be?
Well, it's an antenna swap. Initially, it would involve the addition of a small modem box as well. We're looking to simplify this over time. So, you know, we'll have more to say about that later. You know, I'm not gonna estimate the exact number of days. I think our dealer partners would like to keep that between themselves and their customers. But it's, you know, it's nowhere near as complicated as installing a new system because all the wiring's in place. The main box is in place. You know, the cabin's already been installed with the wireless access points and all that. So it's a lot simpler than starting with a new system. The other point I was gonna make. Sorry, I'm having a senior moment. You'd asked about the amount of time, Louis, and what was the other part of your question?
No, that the complexity, and you basically answered it in terms of the
Yeah
The swap.
Oh, I'm sorry. The other part, the other thing I was gonna say is that because we're gonna be able to start shipping antennas, you know, now that we have PMA, you know, we're probably gonna start, you know, shipping some of the equipment so people can actually get pre-fitted with the antennas and some of the other stuff when they go in for maintenance this year, even though the 5G product isn't launched. They'll just be ready for, like, a box swap when the product actually launches later. We're giving the people essentially an opportunity, if they have a maintenance event, to sort of pre-install a lot of what you'd need to actually implement 5G with AVANCE. Yeah.
Sounds good. Thanks everyone, and congrats on the quarter.
Thanks.
Thanks, Barry. Thanks, Louie.
Thank you. I would now like to turn the conference back to the company for any closing remarks.
Okay, thank you. That concludes our 4th quarter call. We appreciate your participation and talk soon. Have a great day.
Thank you all. I appreciate it.
Thanks, guys.
Ladies and gentlemen, this concludes today's conference. Thank you for your participation, and have a wonderful day. You may all disconnect.
