Good morning, and welcome to Aveanna Healthcare Holdings fourth quarter 2021 earnings conference call. Today's call is being recorded and we have allocated one hour for prepared remarks and Q&A. At this time, I'd like to turn the conference over to Shannon Drake, Aveanna's Chief Legal Officer and Corporate Secretary. Thank you. You may begin.
Thank you, operator. Good morning, everyone, and thank you for joining us today. Speaking on today's call are Rod Windley, Aveanna's Executive Chairman, Tony Strange, Aveanna's Chief Executive Officer and President, David Afshar, Aveanna's Chief Financial Officer, and Jeff Shaner, Aveanna's Chief Operating Officer.

With that, I will turn the call over to Aveanna's Chief Executive Officer, Tony Strange. Tony?
Thank you, Shannon, and good morning, everyone. Thank you for joining Aveanna's fourth quarter and 2021 year-end earnings call. On the call today, we will provide some insights into our Q4 results, update you on current operating and reimbursement environments, bring you up to speed on our most recent M&A activity, as well as lay out our expectations for the full year 2022.
Before we get into these results and the details, I'd like to take a minute and thank the Aveanna team. As you know, this is our first year-end reporting period for Aveanna as a public company. Our legal, accounting, and finance teams have done an outstanding job in preparing us for today. We've successfully completed our audit, finalized the 10-K as well as the proxy all within the required timelines, and have line of sight into accelerating our filings by a few weeks for next year.
In addition, I'd like to thank all of our branch personnel and our caregivers for what you do each and every day. By putting our patients and our families first, you create the foundation on which these results are built. Thank you for your dedication and your hard work.
Let's jump right into our results. As a reminder, at the end of Q3, we acknowledged that the pandemic was continuing to provide disruption to the labor markets, and as a result, we lowered our revenue expectations to a range of $1.675 billion-$1.680 billion. However, through a disciplined approach to managing gross margins, we felt confident that we could maintain our full year EBITDA guidance of $185 million.
I'm pleased to report that for the year ending 12/31/2021, we reported revenues of approximately $1.679 billion and adjusted EBITDA of approximately $184.2 million or 11%. Given the ongoing headwinds of the pandemic, inclusive of the sudden onset of the Omicron variant, we're extremely proud of our year-end results. Congratulations to all of our operators for a job well done in a very difficult environment.
In thinking through our year-over-year comparisons, I'd like to remind everyone that Aveanna uses a 4-4-5 calendar for accounting purposes. As a result, every five years, the fourth quarter has an extra week, making it a 53-week year. Aveanna's 2020 results include this 53rd week, making it a 14-week fourth quarter.
Revenue for the quarter was $414 million, down 1.9% from Q4 of 2020. However, adjusted for the 53rd week for comparative purposes only, revenue would have been up 5.6%. Likewise, EBITDA for the quarter was $45.8 million, up 1.3% over Q4 of 2020. Again adjusting for the 53rd week for comparison purposes, EBITDA would have been up by 9.1%. Jeff will provide further details of our segment results in his prepared comments.
We believe that eventually the pandemic will be in our rearview mirror, and having displayed the discipline to protect our gross margins during these difficult times, we will be well positioned to accelerate growth once again. Along with the disciplined approach to managing expenses, we continue to experience rate wins across our diversified payer platform.
As I mentioned on our last call, 24 of our 31 states have put through rate increases in the last 12 months. For the first time in my career, we have managed care plans, state Medicaid agencies, and even CMS reaching out and asking what can be done to increase access to home and community-based services. We continue to see benefit expansions in several of our key states and are already discussing further rate improvements in states that recently put through rate increases in 2021.
While growing, Medicare represents only 12% of our overall revenue, making it the largest single concentration of any one payment source. We have 31 unique payment systems across as many states. In addition, we have in excess of 250 individual Medicaid managed care contracts. While Medicare is a very good partner in our Home Health & H ospice business, Medicaid is an excellent payer partner in the states in which we operate.
Payers fully understand the impact that COVID-19 has had on access to care and have been not only willing but eager to deploy more resources to manage the care of these individuals in their homes. By way of example, we're in discussions with a couple of payers that are willing to explore new operating and payment models for Private Duty Services that move away from an hourly fee-for-service model to a broader care management model, allowing for greater flexibility in staffing requirements. We believe that our payer diversity, along with our desire to drive innovation within the benefit, provides us multiple opportunities in the expansion of home and community-based care.
Let's turn our attention to our most recent M&A activity. As reported during Q4, both Accredited and Comfort Care transactions closed in December. Both transactions are well into integration, and both are tracking at or ahead of schedule. As you may recall, we expect these two transactions to deliver approximately $200 million a year in annualized revenue. I'd like to welcome all of the employees from Accredited and from Comfort Care to the Aveanna family and to say thank you for all the hard work that's gone into integration thus far. We're excited to have you as part of the Aveanna story.
We had originally thought that we would pay for these transactions through cash on our balance sheet, with some additional debt while maintaining leverage around 4.5x, and then use equity to fill the gap. However, given that the stock was trading at $6-$7 range, we decided that it would be in the best interest of our shareholders to fund the entirety of the transactions with cash and debt, taking leverage to the 6x range. In doing so, we're able to reduce the overall cost of capital and are quite comfortable with the resulting leverage profile.
Given the risk of rising interest rates, we have put in place two different forms of hedges across all of our outstanding debt. While we're comfortable with the current leverage, it's our long-term desire to reduce leverage through accretive acquisitions and/or the use of operating cash flow to pay down debt. David's gonna provide some additional detail on our operating cash flow, debt structure, and the hedges that I just talked about.
As I mentioned on the last call, we will focus the first half of 2022 making sure that these businesses are fully integrated and look for further acquired growth in the second half of the year. As a reminder, we have a $200 million delayed draw term loan for which we're already servicing the spread associated with the debt. In addition, we have $182 million of availability under our revolving credit facility should additional financing be needed. We believe that we're well positioned to continue to grow through acquisitions as opportunities present themselves.
That brings us to where we are now and how we're thinking about the full year 2022. Like most businesses, the Omicron variant has had a meaningful impact on our business. Through most of the pandemic, we had between 200 and 300 caregivers out or quarantined due to COVID at any one time. Beginning in December, we saw that number begin to climb, and it climbed to almost 3,000 caregivers for most of January and February. By mid-March, we saw that number begin to trend back down, and I'm pleased to say that as of today, we're back down to those pre-Omicron levels.
In addition, during the same period, we experienced the great vaccine mandate debate. While the OSHA mandate was ultimately rejected, the CMS mandate has been upheld. While complying with vaccine mandates has been a struggle for most companies, including Aveanna, I'm proud to report that 98% of all of our employees have either been vaccinated or have a qualifying exemption on file, and we are in compliance with all local, state, and federal mandates.
All of these transitory disruptions have had an impact on our business, not only in Q4 but more specifically in Q1. While the impacts of Omicron have subsided, the labor markets continue to offer challenges in identifying and hiring enough caregivers to meet the demand. We anticipate these challenges to continue through the first half of 2022, with much of them being realized in the first quarter.
Keep in mind that Q1 will reflect a full quarter of Accredited and Comfort Care but partially offset by the disruption of Omicron, which could negatively affect revenues in the range of $30 million and EBITDA in the range of $10 million-$12 million. As a result, we believe that revenues for the full year 2022 will be in the range of $1.890 billion-$1.920 billion and adjusted EBITDA will be in the range of $190 million-$205 million or between 10% and 11%.
Notwithstanding further disruptions from additional variants and assuming that the labor market stabilize, we would expect the second half of 2022 to return to a run rate of $215 million-$225 million in EBITDA on an annualized run rate basis. In summary, Aveanna is a diversified home care company generating $1.9 billion in revenue with EBITDA margins between 10% and 11%, and we will consistently grow in the low- to mid-teens year-over-year.
We have an excellent track record clinically and a strong commitment to compliance. Like Medicare, Medicaid is an excellent payer for home and community-based care. The demand for our service has never been higher, and the sentiment from regulators and payers alike is that home care is a solution, not a problem. We believe that Aveanna is positioned to continue its role as a leader in the provision of care and the innovation that will redefine home care as we know it today. With that, I'll turn the call over to Jeff for a little bit deeper dive into our segment results.
Thank you, Tony. Before I dive into Q4 and our 2021 year-end operating indicators and key metrics, I'd like to spend a few minutes on our COVID vaccination efforts, Omicron variant impact, and caregiver employment trends.
As Tony mentioned, we are very pleased with our overall Aveanna vaccination and approved exemption rate of 98%. Our collective efforts to fully vaccinate our staff has largely been achieved, and at this point, all new employees are documented with a vaccine or qualified exemption at their hire date. While this was a major push for 2021 and specifically Q4, we are in full compliance with local, state, and federal laws regarding vaccination status. Going forward, we see this process being a part of how we manage the business day to day.
The Omicron variant had an impact on our December results as it picked up steam aggressively into the new year. We experienced the greatest disruption from Omicron in Q1 of 2022, as it affected almost 10x the number of quarantined employee cases. Prior to December, we averaged 200-300 employees per week in quarantine status and therefore not working. By late December, that number had grown to over 1,000 employees per week, and at its peak in Q1, almost 3,000 employees per week in quarantine. Although short lived, Omicron left a significant mark on our ability to staff open shifts, admit new patients, and complete even day-to-day branch tasks.
Now on to caregiver employment trends. Without the benefit of knowing the impact of the upcoming Omicron variant, we made the strategic decision to invest in a one-time effort to reengage caregivers and provide them with a monetary incentive to stay engaged or return to Aveanna. We refer to this program as the return to work program.
In short, the program began in December and ran through December 31st . During the program, caregivers were incentivized to do one of the following: either, a, join Aveanna as a new nurse, b, rejoin Aveanna if they previously worked for us but had left, C, work additional hours if they already worked for us, or lastly, commit to working exclusively for Aveanna.
Leading up to the onset of Omicron, we saw 10 straight weeks of increased caregiver engagement. On a one-time basis, we invested close to $11 million in cash to run the program, with moderate success. The return to work program has ended, and at this time, we do not have plans to reinstitute similar programs for 2022.
Now on to the Private Duty Services segment. During Q4, we produced $330.5 million of revenue. Revenue was driven by approximately 9 million hours of care provided during the quarter or a 7.7% decline in volume over Q4 2020. The 7.7% decline in PDS volume is adjusted for the comparable 13-week Q4 2020.
Patient demand continues to be at all-time highs as we continue to partner with children, hospitals, and payers to find new solutions to get our pediatric patients home. The primary drivers of the decline in volume was the number of caregivers exposed to Omicron and the overall labor shortages. I do expect PDS hours to improve in Q1 2022 on a sequential basis, even with the impact of the Omicron variant.
Our Q4 revenue per hour of $36.56 was up $1.85 from Q4 of 2020, or 4.6%. This was primarily driven by reimbursement rate improvements and Medicaid program enhancements. With 24 2021 PDS rate increases, we continue to actively pass through wage rate improvements to our caregivers. We are already experiencing rate wins into 2022 and expect this trend to continue as we progress throughout the new year.
Turning to our cost of labor and gross margin metrics. We achieved $86.7 million of gross margin or 26.2% in Q4. However, when adjusted for the approximately $11 million invested into the return to work caregiver program, our Q4 comparable gross margin would have been 29.6%. As this caregiver program was one-time investment in Q4, I expect PDS gross margins to remain in the 29%-30% range moving forward.
Our spread per hour of $9.59 was also impacted by the return to work program. On a comparable basis, Q4 spread per hour would have been $10.81, down from its peak of $11.18 in Q3 of 2021. As I mentioned during our Q3 call, we continue to pass through the rate increases in the form of strategic investments in caregiver wages to drive volume growth in our PDS segment. Long term, I still believe $10-$10.50 is the ideal spread per hour target, balanced against a 3%-4% year-over-year organic volume growth, for our PDS segment.
As Tony mentioned, we closed on the Accredited Home Care acquisition in December. Our IMO team is working through the integration plans, and I am pleased with the progress we've made to date. We expect to wrap up the Accredited integration and synergy capture by the end of Q2. California continues to be a very important state to our Aveanna story, and the Accredited business only further strengthens our position.
Moving on to our Home Health & Hospice segment for Q4, where we have continued to expand our geographic presence in Alabama and Tennessee with our acquisition of Comfort Care. I'm pleased to share that we are moving efficiently through integration and the Comfort Care team has assimilated very well into our Aveanna family. The business is performing in line with expectations, and we expect to finish integration and the majority of synergy capture in Q2.
During the quarter, we produced $48.7 million in revenue, a 181% increase over Q4 2020. This growth was driven by 10,500 total admissions, approximately 67% being episodic, and 11,000 total episodes of care. These volumes are in line with the Q4 seasonality of the home health business and reflect the impact of the Omicron variant in December. Revenue per episode for Q4 was $2,942, up 1.7% from Q3.
On a current run rate basis, our Home Health & Hospice division is approaching $300 million in annualized revenue. I'm pleased with the organic growth rates of our Home Health & Hospice business and believe it will remain a high- single-digit admission growth segment for Aveanna.
From a cost and margin perspective, Q4 gross margins were 45.9%, primarily driven by higher seasonal PTO usage and the temporary impact of the Omicron variant in December. 2021 annual gross margins were 47.2%, and we believe there remains additional room for improvement. We see the Home Health & Hospice business segment's ideal gross margins landing in the 48%-50% range.
Lastly, we continue to ramp up our clinical innovation investments to support the value-based purchasing efforts in home health. We are well positioned for value-based purchasing and look to benefit from its nationwide expansion in 2023.
Now, on to our Aveanna Medical Solutions segment results for Q4. During the quarter, we produced $34.9 million of revenue. Revenue was driven by approximately 77,000 unique patients served, UPS, or revenue per UPS of $453.39. Revenue per UPS was down approximately $10 or 1.9%. The primary driver of rate decline was the impact of the national enteral contract we signed effective September 1st, 2021. The longer-term impact on rate per UPS should normalize in the $440-$460 per UPS range. Lastly, from a volume perspective, adjusted for the 13-week Q4 2020 impact, volumes for Q4 were flat year-over-year.
We're experiencing enteral product supply chain delays that have temporarily burdened our ability to fill orders. In some cases, we have patients needing specialty enteral products, and the supplier doesn't have inventory available. We see these supply chain issues as temporary in nature and are working with our distribution partners to immediately address them.
Turning to our cost of goods and gross margin metrics. We continued to experience stability in gross margin, with $15.4 million in Q4 or 44.1%. Medical Solutions 2021 gross margin of 44.6% was in line with our expectations. Moving forward into 2022, we expect gross margins to remain in the 41%-43% range as a result of the impact of the national payer contract mentioned above and pressures on supply chain product availability.
Finally, the demand for our enteral nutrition product and services continue to be very robust. Our industry-leading clinical model and highly efficient distribution network will allow us to weather the short-term impact of the supply chain shortages. We remain upbeat about the long-term value that Medical Solutions provides and its positive growth impact to Aveanna as a whole.
In summary, all three of our business segments have proven to be very resilient in a challenging environment. I am proud of our disciplined approach to managing margins while investing in additional caregiver wages. The Aveanna team is dedicated to providing high- quality and cost-effective health care in our patients' homes. Regardless of the short-term market conditions, home care remains the number one choice of our patients, families, referral sources, and payers. With that, I'd like to turn the call over to Dave for additional color on 2021. Dave?
Thanks, Jeff. Tony and Jeff have provided some details on the fourth quarter, and I'll go ahead and provide an overview of fiscal year 2021, as well as provide some cash flow, debt, and hedging details. Starting out with revenue: 2021 revenue was $1.68 billion, an increase of $184 million or 12.3% from 2020.
Our 2021 revenue growth was primarily attributable to $146 million of growth in our Home Health & Hospice segment, as our 2020 HHH M&A contributed a full year of revenue in 2021, as well as incremental partial year revenue provided by our 2021 HHH M&A. Our PDS and Medical Solutions segments also contributed incremental revenue of $28 million and $9 million, respectively, to our 2021 revenue growth. As Tony and Jeff both mentioned, fiscal year 2020 contained 53 weeks, as compared to 52 weeks in 2021, which affects the comparability of our 2021 key performance measures to 2020.
Now turning to gross margin. Our gross margin percentage increased to 32.3% in 2021 from 30.4% in 2020. This was attributable to the significant growth in our HHH business, which has a higher gross margin percentage than our PDS business, as well as a 50 basis point increase in our PDS gross margin percentage.
Field contribution margin also increased 30 basis points to 14.6% in 2021 from 14.3% in 2020. As we think about Field contribution, recall that while HHH has higher gross margins relative to PDS, it also has higher branch and regional administrative expenses. As a result, we would not expect to see the full amount of the increases in gross margin percentage flow through to Field contribution margin.
Corporate expenses were 7.8% of revenue in 2021, as compared to 7.6% of revenue in 2020, primarily as a result of growth in our non-cash share-based compensation costs, as further discussed in footnote 13 to our financial statements and in our MD&A. Adjusted corporate expenses, however, decreased from 5.5% of revenue in 2020 to 5% in 2021. The principal adjustments from corporate expenses to adjusted corporate expenses in 2021 include integration costs and non-cash share-based compensation, and can be found in the corresponding table in our press release.
I'd like to provide a little color on the goodwill impairment charge [we recorded in Q4. We observed a] significant decline in our market capitalization over the course of 2021. The continuing impact of COVID-19 on our business has pressured our clinical workforce and caregiver availability in our core PDS businesses, thereby constraining PDS volume growth and expectations. As a result, we recorded a $117.7 million impairment charge in our PDS segment in the fourth quarter.
Moving on to net operating loss, net loss and adjusted EBITDA. Operating loss was $36.1 million for fiscal year 2021, as compared to $3.5 million in 2020. While operating loss was positively impacted by a $31.5 million increase in Field contribution in 2021, the primary driver of the increase in operating loss was $42 million of incremental goodwill impairment charges that we took in 2021 versus 2020.
Net loss was $117 million in 2021 compared to $57.1 million in 2020. There are a number of moving parts driving the increase in net loss, which you can see in our income statements, with the primary drivers being the increase in operating loss I mentioned earlier, as well as the absence of a $50 million legal settlement that we received in 2020. As Tony mentioned earlier, we were pleased to report adjusted EBITDA of $184.2 million for fiscal year 2021, a $31.8 million or 21% increase from 2020. This represents an 11% adjusted EBITDA margin for 2021.
Turning to operating cash flow. Net cash used by operations was $11.4 million in 2021. Bear in mind, though, that this included $38.1 million of cash repaid to government agencies in 2021 related to certain CARES Act items, including $25.9 million paid to the IRS for payroll taxes that we deferred in 2020 and $12.2 million paid to CMS for advances received in 2020 by certain of the companies we acquired.
Over time, some of our analysts and investors have asked questions about how to think about GAAP operating cash flow in relation to adjusted EBITDA, and I want to provide some color on that here. When you think about our operating cash flow in relation to our adjusted EBITDA, there are a couple significant drivers of variances between the two, with the largest being cash paid for interest.
In 2021, cash paid for interest was $59 million. As a result of rising forward-looking market expectations for interest rates in 2022, based on current leverage, we expect the cash paid for interest will increase in 2022 and be more significant in relation to our adjusted EBITDA.
Our M&A-related costs also create a variance between adjusted EBITDA and operating cash flow. M&A-related costs include acquisition-related costs and integration costs, both of which you can find in our adjusted EBITDA reconciliation in MD&A and which approximated $30 million in 2021. COVID-related costs were $19 million in 2021, which can also be found in our adjusted EBITDA reconciliation.
One last item is the $38.1 million of cash repaid to government agencies in 2021 related to the CARES Act items that I mentioned a moment ago. This caused, in part, working capital to drive a significant variance between adjusted EBITDA and operating cash flow in 2021.
To finish up on this topic. And overall, hopefully, this provides some useful color on some of the larger drivers of variances between adjusted EBITDA and operating cash flow. I would also encourage you to review our statements of cash flows included in our audited financial statements, as well as our adjusted EBITDA reconciliation in MD&A, because the examples I've provided here are not all inclusive but again intended to provide useful reference points and color.
I'll now provide a credit facility and hedging update. As a refresher, after our IPO last April, we used $407 million of the proceeds to fully repay our second lien term loan at the time and pay $100 million down against our first lien term loans. In August 2021, we refinanced our first lien term loans into a single $860 million first lien term loan bearing interest at LIBOR plus 3.75% with a 50 basis point floor.
In Q4, we entered into a new $415 million second lien term loan to finance our Q4 M&A for the reasons that Tony mentioned earlier. The new second lien term loan bears interest at LIBOR plus 7%, also with a 50 basis point LIBOR floor. In Q4, we also entered into a $150 million accounts receivable securitization facility. In aggregate, we had $1.39 billion of outstanding variable- rate debt as of year-end.
We do have two hedges in place against our debt. The first is a $520 million notional interest rate swap that converts $520 million of variable- rate debt to fixed- rate debt. The swap expires in June 2026. We also have an $880 million notional interest rate cap, which caps our exposure to LIBOR increasing over 3%. The interest rate cap expires in February 2027.
In summary and as I wrap up here, our 2021 operating results underscore the resilience of the Aveanna team amidst a challenging operating environment. Our IPO and subsequent capital structure improvements have prepared us to take advantage of the opportunities ahead of us with liquidity that is supportive of our 2022 acquisition goals.
In addition, I'd like to say a big thank you to the entire Aveanna team for supporting the timely completion of our audit and filing of our first 10-K as a public company. In particular, our accounting, revenue cycle, finance, and legal teams have moved mountains to make it all happen. Our professional services providers, including Ernst & Young and Greenberg Traurig, have provided exceptional service to Aveanna in the process. With that, operator, I think we're ready to open it up for questions.
Thank you. Ladies and gentlemen, at this time, we will be conducting a question- and- answer session. If you'd like to ask a question, you may press star one on your telephone keypad. A confirmation tone will indicate your line is in the question queue. You may press star two if you would like to remove your question from the queue. For participants using speaker equipment, it may be necessary to pick up your handset before pressing the star keys.
In the interest of time, please limit yourself to one question and one follow-up so we may get to everyone's questions. Our first question comes from the line of Pito Chickering with Deutsche Bank. Please proceed with your question.
Hey, good morning, guys. A lot to unpack here. I guess, on the PDS segment, what happens during the first quarter when the patients were unable to sort of be staffed in the first quarter? Do they go back to the hospital? Do they live without care? Or do they go to another provider? How should we think about sort of that rebounding back when your staff is available?
First of all, thank you for your question, Pito. Let me tell you what doesn't happen. They didn't leave and go to another provider. Outside of that, all of the above is probably true. Some patients might have had to seek care in a hospital if they're, you know, ventilator or trach dependent. The most common answer is the family has to pick up that additional care. Mom and dad or grandmother or, you know, brothers and sisters all have to chip in and pick that care up.
You know, I thought where your question was headed, though, that once those hours are lost, there's really no way to go back and make up those hours. To your point, as the caregivers reengage or come back out of quarantine, then we can begin staffing those hours. I think we talked about in the prepared remarks that we really kind of saw that bottom. January and February were pretty dire months in terms of the impact of Omicron. In March, we began seeing those caregivers reengage. Jeff, anything you wanna add to that?
Just the fact that, Pito, like, as Tony said, with this variant, it was really a seven- to 10- day quarantine period. It was a rolling period because it was exposures and positive confirmations on so many different states and different communities.
To Tony's point, we paid those caregivers as if they had worked in that period of time that they were gone, which was our policy all along, which did allow those caregivers to stay with us. You know, this is a very transient group of PRN employees. We felt it was necessary to pay them, to keep them whole through that process. As abrupt as it was, the positive side of it was those nurses and caregivers did come back after their quarantine.
I echo Tony's comments. It's a tremendous burden placed on the parents, on the family. They have to be up with these pediatric children and sometimes 24 hours a day, you know, stay with them while they're sleeping. You can imagine the family and the pressure it puts on them, b ut you know, we are pleased to be able to reengage the caregivers after the quarantine period was over.
Okay. One sort of guidance question. I assume that there'll be a lot of questions around guidance today, but sort of, you know, two parts. The first one, can you sort of help me bridge, you know, what fourth quarter EBITDA would've been if all the deals had closed at the beginning of the quarter, just, you know, as a launchpad in the first quarter? I was estimating around $53 million. This is in the ballpark.
The second one. You know, with the first quarter effectively closed, you gave guidance on the first half of the year, but can you be more specific about, you know, range of first quarter EBITDA? Just that'll give us sort of the cadence into the rest of the year.
All right. Well, let me see if I can take that kind of one piece at a time. If you think about Q4 with a full quarter impact of both Accredited and Comfort Care. However, let me caution you because we won't have realized all of the synergies that quickly in the Comfort Care and Accredited deal. Remember the synergies will roll on as we move throughout really the first half of 2022.
Pito, I wanna be careful because we don't really provide quarterly guidance. If you were to take our fourth quarter numbers and think that there's probably another, you know, call it, $6 million, you know, $6 million-$7 million of additional EBITDA associated with having the full year of, I mean, a full quarter of Accredited and Comfort Care in place, and then offset that by the impacts of Omicron, t hat's kind of how to think about fourth quarter, moving into first quarter.
However, for all the reasons we've already talked about, the Omicron variant really impacted our business January and February. You can really see it across all three segments. However, the most significant was private duty because that's where we got one nurse, one patient, and if that nurse is not working, you know, revenue is not being generated.
We think the impact of that in Q1 is gonna be pretty significant. I think in my prepared remarks I painted a picture where we could see revenues being off in total, you know, in the range of $30 million in Q1 and, you know, impacting EBITDA, which is really a gross margin number, kind of in that $10 million-$12 million. For those reasons, you know, our full year outlook is reduced by the impact of what we're gonna experience in Q1 and maybe bleeding into Q2 a little bit. That's the picture that we're trying to paint.
We're actually giving more color than we would be accustomed to because when you're thinking about Aveanna being a, you know, I think, the numbers we use, $215 million-$225 million EBITDA run rate company, I think that's still the right way to think about our business. It's just we're gonna have a different starting point because of the impact that Omicron had in Q1.
Our next question comes from the line of Sarah James with Barclays. Please proceed with your question.
Thank you. I'm gonna stick on the guidance topic here for a little bit. You guys mentioned a couple other moving pieces. You've got really strong rate increases coming through, which generally tend to affect PDS hours. Can you talk about the cadence of rolling those out? Should we think about them being fully put into your hourly rates for the full year, starting in 1Q? And then the supply chain issues that you flagged, are those included in guidance, and do you think about it just being a 1Q issue?
Jeff, in a minute, I'll want you to answer the question about how we're thinking about the rate increases flowing through in 2022. You know, Sarah, because you were kind of pulling at that Q1 number, let me remind everybody that in Q1, especially in private duty where everything is so labor intensive, we typically see a higher payroll tax impact during the first quarter. That really kind of rights itself in March and April. That's another thing that's gonna pull on that first quarter a little bit.
I think, some of our most recent increases you've actually seen in a portion or some of Q4, we'll get to experience that in the full quarter. As both Jeff and I mentioned in our prepared remarks, we're already seeing, in some cases, some of the same payers that put through rate increases in 2021 back at the table in discussions with 2022. With that, Jeff, why don't you comment about how we think about those, you know, playing
Yeah.
Throughout the course of the year.
Yeah. Hey, Sarah. Yeah, I think Tony said it well. You know, we already have four rate increases that are in the books for this year. Those have effective dates, you know, in Q1 and Q2. We're already engaged with dozens of other states as they trend towards their usually July 1st and September and October 1st fiscal year- end and year beginning date. I think we'll see ourselves, you know, back in the mid, probably mid-teens, high teens from rate wins.
Then I think, you know, we've continued to evolve our strategy around increasing the benefit opportunities through home and community-based services, and we see a real opportunity to continue to do that this year. I think, as Tony mentioned, you know, a lot of the burden has fallen on the families, the parents that are with these children every day.
I think that we see, you know, a couple of states that embrace the parent being a lesser- skilled worker, and we are continuing to lobby for that acceptance in more states. We had one state adopt that this year, 2022. I think we'll see more states adopt that family member becoming a, you know, becoming a full-time caregiver of ours on the lesser skill or unskilled piece.
The second part of that was the supply chain for AMS. You know, Sarah, that really kind of built up over, I'll call it, the last four months of last year as the supply chains, as we saw the ships out in L.A. port. You know, some of those ships have our enteral specialty products, and they're coming from Europe. And we just saw that our distribution partners were starting to run thin on inventory, especially on the specialty products, n ot as much the generics but the specialty products.
You know, many of our young-young kids, kids, you know, kind of, you know, zero-five age, really are on specialty formulas that are very specific to their disease state. Getting those products and getting them back in the shelves so we can distribute them was a big deal. I do see light at the end of the tunnel in that.
I think, as we look forward, certainly Q1 continued to be pressure on the supply chain as it related to AMS supply. I think, as we look out, we see some of the issues being solved in Q2 and then, certainly by summer, much of that inventory being resupplied so that we can ship every and any medical solution enteral product that is needed at the time the patients need it.
Great. Just one follow-up here on rates. Can you help us understand, are there any states where the rate enhancements have been part of a multiyear budget so you have some go-forward clarity? As we come to the end of the public health emergency and the enhanced FMAP is rolled back, are you guys having any discussions with states on their view of program funding?
Yeah. That's a great question, Sarah. I think I'd answer both; o r maybe, c, all the above. We've got permanent rate. Looking backwards, of the 24 of those, we have permanent rate. We have temporary rates that have continued to be temporary and moved into the future around the public health emergency.
Lastly, I would say we're also seeing one-time payments. States that are using the home and community-based services Fed rewards as one-time payment updates. You know, the thing that we're most focused on is long-term rate. We're most focused on moving the rate long term to continue to attract nurses.
I would say, secondary to what I said before, we are very focused at moving the benefit, you know, additional services, both of skilled, non-skilled services. Also, as Tony mentioned, we now have audiences with the largest Medicaid managed care providers in America talking about a different payment model.
I think that's what excites us the most is they have come to us and said, "Let's come up with a different solution to where we can keep these kids out of the hospitals, keep them safe at home, and truly reduce the total cost of care." That to us is the exciting part of the future.
Sarah, I'll answer the other side of your question, though, and maybe I interpreted it wrong. If your question related to what is the risk of downside in the event that rate were to pull back, I can tell you that, in our view today, we don't have any rates that are pulling back. Our rate is only gonna be where it is or positive from here for the foreseeable future.
Thank you, Sarah.
Our next question comes from the line of A.J. Rice with Credit Suisse. Please proceed with your question.
Hi, everybody. I just wanna make sure I understand. I know there's a lot in the first quarter going on for 2022, but when you look at the rest of the year, and I understand there may be a little spillover into the second quarter, your revenue growth assumption for the back half of the year, if you take out the contribution from acquisitions, have you changed your thinking about what the organic growth was?
I think we talked about this year, because of labor, originally not being the 8%-10% organic growth but maybe being more in the mid-single digits. It almost looks like, unless I'm doing the math wrong, which is possible, you're now looking at something in the low single digits. Is that right? Can you give us a little more flavor on what's baked in acquisition versus organic in the as you come out of the Q1 noise?
Yeah. A.J., nothing has changed in our thought process. Matter of fact, and I'll even unpack it a little bit further, w e still think of that private duty business, that core private duty business, in the skilled side of that. We're growing in that, you know, 3%, 3%-4% range. In the unskilled side of private duty, you know, that business, to all the reasons Jeff talked about, we expect it to grow in the high single digits.
Our Medicare Home Health & H ospice business is gonna grow in the high single digits. Our AMS business is gonna grow in the high single digits. You know, overall, I think our growth rate, we still believe, will be in that, you know, 5%-6% year-over-year organically. I think, as you see us get through the end of 2022, we're assuming that those kind of growth rates are, you know, will come back. I don't think our thoughts have changed at all.
I think maybe what you might be seeing is kind of the ramping back of the big dip that we're taking here in the first half of the year. I think you're seeing some of the impact of ramping that back. You know, we have a little bit of seasonality that we have to contend with for Q3.
In general, Q3 is usually one of our lower quarters, so you may be seeing that built in. I don't think our sentiment on the overall business has changed at all. If anything, I think we see that there's opportunity for upside on that. Our Home Health & Hospice business is growing. You know, some of the creative and innovative things that Jeff talked about with some of our payers, where we're now able to hire family members to provide care and have greater flexibility with staffing, I think all of those things will go into accelerating growth rates.
Okay. Maybe similar question on the labor front. I know, a lot of moving parts in the fourth quarter, in the first quarter. Again, as you move into the second and then definitely the second half, what is your assumption about year-to-year labor costs on whatever metric you're looking at it for both the PDS business and the adult h ome business? W hat kind of increase are you assuming baked into that guidance?
Well, you know, I think the best way to think about that, A.J., is in Jeff's prepared remarks, he referenced spread again. Instead of focusing on the margin, we will kind of focus on that spread. In states where we see rate increases, we will take those rate increases and, in a very disciplined manner, pass some of those rate increases along in wages to our caregivers.
And that in and of itself will help facilitate growth, b ut as it relates to the spread, we're gonna be very disciplined about passing these rate increases through to caregivers in the form of wages because we have to manage the gross margin. In this business, once you give up the gross margin, you will never get it back.
It takes that 30% gross margin, you know, for us to run that business, and we'll be disciplined about it. I guess what I'm trying to paint a picture for you, when we get a rate increase in a state, and I'll let, Jeff, you comment on this, we just don't say, "Okay, well, let's just give everybody an increase across the state." You know, it's market by market and sometimes patient by patient.
Yes. And A.J., as Tony said, you know, the rate increase is effective on one specific date for all patients that fit a certain, you know, reimbursement model. Then to Tony's point, it takes us weeks, in many cases months, to spread that wage rate out. And that's why I think, our spread, we feel confident, will still be in that probably north of $10.50 range in PDS and in Q1 and probably closer to $10.50 in Q2.
On the adult side, I think as we said in our prepared remarks, we still see room for a gross margin improvement. I think, you know, we're still growing our systems and our KPIs for our home health and now our hospice business. You know, I think we were in the 47% range at the end of last year, for the full year, and we see that probably growing into the, you know, 48%-49% range in 2022. I think there's still room for improvement on the HHH side.
Jeff, I think the best demonstration of that. G uys, I'm doing this all from memory, but if you go back to Q1 of 2020, I believe the spread was right at $10.50. In Q2, it went to $10.80, and then in Q3, it jumped all the way to $11.18. Both on our Q2 call and on our Q3 call, Jeff, we talked about having to pull that number back a little bit because, at $11.18, that's actually running a little bit hot.
What you're seeing play through 2021 is exactly what we said would happen, is that as these rate increases come through, there is somewhat of a lag time between that and when you start passing those down through wages. I think, you know, the spread Jeff talked about today was just over $10.80, I think, is a good demonstration of that, you know, putting some of those dollars back to work. We'll continue to do that in a stair step function as these rates continue to improve throughout 2022.
Our next question comes from the line of Brian Tanquilut with Jefferies. Please proceed with your question.
Hey, good morning, guys. Just shifting gears a little bit. I know there's been a lot of discussion on gross margins, but as I look at your regional and corporate expenses down sequentially and even down year-over-year in corporate, I'm just trying to figure out the durability of these levels and how you're thinking about kind of like G&A growth going forward.
Well, we'll you know, when we grow through acquisitions, those are the areas where we'll get the most synergies. As I made a comment a while ago, you know, we will begin to see the synergies associated with, you know, a $200 million increase, associated with Accredited and Comfort Care. We'll begin to see those synergies flow through in the first half of the year. In terms of durability, we think we will be able to continue to control those expenses and leverage those expenses as the company grows.
Now, some, you know, some of that is attributable to, you know, some insurance premiums and other things like managing through accrued incentives. You know, every single quarter, we true up incentives to where the business is operating that day. All of those things will continue to play through. We think the leverage is quite sustainable at the SG&A line for corporate, regional, and area expenses.
Got it. Tony, since we're on the topic of home nursing, I know you said that the two acquisitions are performing at or above plan. Just any comments you can make in terms of what you're seeing in terms of like nurse recruitment and the referral patterns that you're seeing coming out of the hospitals as you've started digesting those two assets?
Well, as it relates specifically, I'm gonna broaden your question. As it relates specifically to those two assets, their businesses are doing well. We've not seen any slowdown or pullback from referral volumes or admissions or hours staffed. So those two businesses specifically are doing great. You know, matter of fact, I'll tell you, the folks out at the Accredited deal in California, that's been a pleasant surprise. Their volumes have not only held but improved. We're really excited about both those transactions.
I'm gonna expand your question a little bit, and I think both Jeff made a comment about it, and so did I. The demand for our services has never been higher. You know, we have, especially on the private duty side, we have patients in hospitals waiting to come home. As a matter of fact, we referenced this at our most recent health care conference. There's now a Los Angeles Times article. There's a Philadelphia Inquirer article. There's a Washington Post article all around patients waiting to come home and the lack of access to care, for home and community-based care.
We think this just creates a tremendous tailwind going forward, that people have to recognize and investments need to be made into expanding home and community-based care through some of the innovative things that Jeff talked about. You know, let's pay, you know, caregivers. Let's pay family members to keep these patients at home. I think we're well positioned to, you know, lead that innovation, and we're pretty excited about it.
Our next question
Thanks, Brent.
Comes from the line of Matt Borsch with BMO Capital Markets. Please proceed with your question.
Sorry about that [audio distortion] how you expect [audio distortion] markets to shake out as we get to the [audio distortion] would agree with your assumption that [audio distortion] let's all hope [audio distortion]. You know, how do you [audio distortion] within that estimate that [audio distortion] constraints [audio distortion] .
Matt [crosstalk].
Mr. Borsch, your line is cutting in and out.
Yeah. Matt, I mean, operator [crosstalk] .
Okay. Is that better?
Matt, I'm sorry. You were cutting in and out. We couldn't hear your question.
[audio distortion] try again, if possible. I'll circle back [audio distortion].
Operator [crosstalk]. Yeah. Operator, I'm sorry. Matt, if you can hear us, we'll be glad to catch up with you in a little bit. Operator, maybe we'll go to the next question while Matt sorts out his audio.
Our next question comes from the line of Joanna Gajuk with Bank of America. Please proceed with your question.
Yes, good morning. How are you? Thanks so much for taking the question. I guess, one question and one follow-up. The one question, in terms of the cash flow. S o obviously you highlight a couple of these different things that impacted, you know, last year. How should we think about the cash outlook for this year going forward?
Joanna, thanks for your question. You know, I think we have a good cash flow generation opportunity. You know, when you look at the net cash used of $11 million in 2021, you know, just recall that $38 million that I mentioned that we repaid related to CARES Act items on the deferred payroll taxes as well as the CMS advances. So that $38 million, you know, weighed down our cash used for operations in 2021.
You know, I'd say, you know, when you think about the overall flux in cash flow year-over-year, you know, that change might jump out at you. You know, again, consider some of the non-recurring items that bring the change into perspective. You know, the biggest driver of the year-over-year change in cash flow was $47 million of cash provided in 2020 related to those social security taxes that we deferred as permitted by the CARES Act.
In 2021, we repaid $26 million of this to the IRS in the fourth quarter. That's a comparative usage of $73 million in operating cash year-over-year. The other significant item driving the flux was a $50 million legal settlement we received last year.
As we look out, you know, into 2022, we expect to generate positive operating cash flow. Bear in mind that we will pay another $25 million or so to the IRS in the fourth quarter of 2022. Those are some of the larger moving parts in cash flow, but I also direct you to our liquidity and capital resources section in the 10-K for some more insight on that.
Right. Because I guess, now with additional debt for the two deals that you closed in Q4, that's what I was getting at, whether you expect to be, you know, positive operating cash flow, you know, considering the incremental interest expense. It sounds like you think it's gonna be positive for the year [crosstalk].
That's right, Joanna. That's right. I mean we think we've got a good opportunity in front of us. As Tony mentioned earlier, we're already servicing the spread on our delayed draw term loans. Any, you know, M&A that we drive or that we secure with that delayed draw will be, you know, very accretive to operating cash flow.
Okay. If I may, just a follow-up on the discussion previously of in terms of the two acquired assets because, I guess, previously where you talk about, you know, combined. I guess they were kind of running at a $40 million annualized EBITDA. But, you know, it seems like, you know, maybe there was some impact there too. So can you kind of frame for us whether this is still kind of the run rate for those two assets or, you know, how much lower, I guess, you know, they're running at because of the, you know, what's happening in Q1? Thank you.
Yes. I think the answer to your question is we have not changed our thought process or outlook about these acquisitions at all. You know, we still believe that they're going to perform at or better than the model we discussed before. Now, with that said, neither Accredited nor Comfort Care are immune to the impacts of Omicron in Q1. You know, they're experiencing the same kind of staffing issues that we've described, you know, for the rest of our business.
With that said, all of the impact inclusive of Accredited and Omicron were in the numbers that I talked about, where we felt like it was going to impact revenues by $30 million and EBITDA by $10 million-$12 million. That's inclusive of the impact that it would have with Accredited and with Comfort Care. Hopefully, that answers your question.
There are no further questions in the queue. I'd like to hand the call back to management for closing remarks.
Thank you, operator. Again, thank you guys for investing your time in learning about Aveanna and being interested in our story. As always, we've tried to be as transparent as possible. We'll also make ourselves available to anybody that needs to, you know, do some additional follow-up. You know, please give us a call and let us know. I hope you have a great day, and thanks for your time.
Ladies and gentlemen, this does conclude today's teleconference. Thank you for your participation. You may disconnect your lines at this time, and have a wonderful day.
