Carey Smith
Thank you, Dave. Good morning, and welcome to Parsons' fiscal year 2023 and fourth-quarter earnings call.
I want to start by thanking all 18,500 employees Parsons Corporation for their contributions to an exceptional 2023. We executed on our growth strategy, delivered our customers' critical missions, and achieved record financial results for our shareholders.
For the full year and the fourth quarter, we delivered the strongest financial results since our IPO, including records for total revenue, organic revenue, adjusted EBITDA, operating cash flow, and contract awards.
Starting with the full year, we exceeded $5.4 billion in revenue for the first time and delivered record organic revenue growth of 23%, making us an industry leader in both our federal solutions and critical infrastructure segments. We had consistent results throughout the year with organic growth in excess of 20% for each of the last three quarters of the year and double-digit organic growth in all four quarters.
Our strong results for the year were driven primarily by our ability to win and ramp new contracts, strong hiring and retention, and on-contract growth.
In 2023, we delivered over $460 million in adjusted EBITDA for the first time in our company's history and continue to expand our margin achieving 13 basis points of improvement for the year. Total revenue grew 30%, while adjusted EBITDA increased by 32%. Our ability to drive adjusted EBITDA grow faster than our revenue growth demonstrates our focus on margin expansion.
For the full year, our contract awards increased 40% to a record $6 billion, which equates to a 1.1 times book-to-bill ratio. In addition, our fiscal year 2023 cash flow increased by 72% over 2022 to a record $408 million.
For the fourth quarter, total revenue increased 35% year over year and 34% organically. Adjusted EBITDA grew by 30% over the prior year period, and cash flow from operations was $190 million. During the fourth quarter, we won two single award contracts worth more than $100 million each. This brings our total contract wins that are greater than $100 million to [15] for the full year, a new record for Parsons. Our ability to successfully deliver on our customers' missions has allowed us to continue to win new work and secure [big peaks].
Also, our exquisite federal solutions portfolio is aligned with national security's near-peer threat priorities, and our digitally enabled critical infrastructure business is capitalizing on unprecedented global infrastructure spend.
Significant fourth quarter wins included a single award classified contract for continued a new work and support of the United States government. This five-year contracts valued at over $250 million, of which we booked $50 million in the fourth quarter. A new $150 million single-award contract to serve as lead designer on a major infrastructure replacement project in the northeast United States. We plan to book the full value of the contract in the first quarter of 2024.
A new $80 million contract to provide remediation of lead contaminated soil for United States customer. We booked $73 million on this contract in the fourth quarter. We were also awarded a prime position on two multiple award IDIQ contracts. The first one is a new five-year contract for the Army Corps of Engineers with a ceiling value of $245 million for environmental remediation. This contract includes infrastructure investment and Jobs Act funding related to environmental protection, [HC] cleanup projects. We continue to win significant environmental remediation projects.
During the fourth quarter, we also completed our comprehensive assessment investigate for a major Fortune 100 industrial clients. We completed this project from investigation to treatment without causing any downtime for the customer's facility, which is a testament to the innovation, creativity, and expertise about multidisciplinary PFAS team.
Parsons water treatment lab in Syracuse, New York has been a leader in water treatment innovation for more than 30 years.
The second multiple award contract that we won in the fourth quarter is a new five-year General Services Administration, public building services program. In this contract is an estimated selling value of $200 million.
After the fourth quarter of 2023 ended, we were awarded two significant contracts. We were selected by the Department of Labor Job Corps to assist with planning, management, and oversight of their facilities program. This single award five-year [recompete] contract has a ceiling value of over $115 million.
We were also awarded a new three-year $87 million contract to provide project management services for a major tourism and entertainment development project in the Middle East.
During the fourth quarter, we completed the acquisition of I.S Engineers, which is a Texas-based full-service consulting engineering firm that specializes in transportation engineering, including roads and highways and program management. This acquisition adds critical infrastructure talent and strengthens our portfolio in this large and growing state. Texas is poised to receive nearly $30 billion in total transportation funding from the infrastructure investment and Jobs Act between 2022 and 2026.
The acquisition of I.S. Engineers marks our third acquisition in 2023, which includes two acquisitions in critical infrastructure and one of federal solutions.
In addition to bolstering our critical infrastructure portfolio through strategic acquisitions, we strengthened and reorganized segment to better align with our customers, geography, and end markets and better position Parsons to capitalize on the unprecedented global infrastructure spend. For informational purposes, we have provided historical financial results in the back of our earnings press release for our new business units.
As part of our 80-year history of cultivating a responsible enterprise, Parsons is proud to be recognized with the highest achievable score of 100 by the Human Rights Campaign Foundation on their 2023-2024 for Corporate Equality Index for active support and inclusion of the LGBTQ+ community.
In addition, Parsons was recognized as a Best for Vets company by the Military Times for supporting veterans post-military careers. In 2023. We were also named as one of the world's most ethical companies by Ethisphere for the 14th consecutive year, one of the world's best companies by Time Magazine, and one of the best employers for diversity by Forbes.
In summary, we are executing on our strategy and delivering our customers' missions as we continue to post record results and strong growth rates across all financial metrics. We also expanded margins and closed an accretive acquisition that strengthens our engineering expertise and increase our footprint in a high-growth geography.
As we enter 2024 and the 80th anniversary of our company, we are excited about our long-term prospects. We are well positioned into high growth and complementary segments that continue to experience significant tailwinds. Starting with federal solutions. The proposed defense budget supports an [$886 million] top line budget, which is 3% higher overall than 2023. However, the Parsons core defense markets are growing at mid to high single digits. Given worldwide geopolitical events, we continue to see strong demand for our solutions, including cyber, electronic warfare, signals collection, space, missile defense, and critical infrastructure protection.
Our focus remains on outpacing our nation's near-peer threats with our differentiated solutions.
In critical infrastructure, global demand remained strong in all three geographies where Parsons operates, the United States, Canada, and the Middle East. We are leveraging our core competencies and engineering design, program management, and owners' representative to win and deliver a large complex programs. As an industry leader in applying digital transformation and infrastructure, we look forward to continuing to transform this industry.
Given our strong performance in our confidence in our current outlook, we are pleased to update the long-term guidance we provided at our Investor Day on March 15, 2023. Matt will share more details. But in summary, we're raising our revenue growth targets, which is also up a total revenue base that is $1.2 billion higher than it was at the end of 2022.
In addition, we expect to average 20 to 30 basis points of margin expansion each year through 2025 and our free cash flow conversion rate of 100% or more adjusted net income. We also expect to continue to supplement our organic growth with two to three accretive acquisitions per year in order to enhance our technology differentiation, move further up the integrated solutions value chain, and drive additional shareholder value.
With that, I'll turn the call over to Matt to provide more details on our 2023 financial results, 2024 guidance, and our enhanced long-term financial targets. Matt?
Matthew Ofilos
Thank you, Carey. As Carey indicated, our fourth quarter and fiscal year 2023 were highlighted by record results in a number of areas, including total revenue, organic revenue, adjusted EBITDA, operating cash flow, and contract awards.
Total revenue of $1.5 billion for the fourth quarter of 2023 increased 35% from the prior-year period and was up 34% on an organic basis. Adjusted EBITDA of $128 million increased 30% from the fourth quarter of 2022, and adjusted EBITDA margin decreased 30 basis points to 8.6%. The adjusted EBITDA increase was driven primarily by accretive organic growth on recent contract wins as well as growth on existing contracts.
Our adjusted EBITDA growth for the quarter was negatively impacted by a net $20 million headwind from adjustments on two separate programs. On the first program, we reached a positive proposed judgment on rail and transit project for which we realized a $38 million favorable impact to fourth quarter in adjusted EBITDA.
On the second program within equity and earnings, we took a $58 million adjusted EBITDA charge. The impact of the result of supply chain challenges identified during the procurement of materials. Normalized margins, excluding two adjustments, would have been 9.9% and 8.9% for the fourth quarter and full year, respectively.
Total revenue for the fiscal year 2023 increased 30% from prior year and was up 23% on an organic basis. The strong organic growth throughout the year was driven by the ramp up of recent contract wins and growth on existing contracts. Acquisitions contributed approximately $274 million of revenue for the full year.
SG&A expenses for the full year were 16% of total revenue compared to 18.5% in 2022. Intentional focus on efficient spend positions the portfolio well to continue to drive margin expansion. Fiscal year 2023 adjusted EBITDA of $465 million increased 32% from 2022, and adjusted EBITDA margin increased over 10 basis points to 8.5%. The adjusted EBITDA increases were primarily by increased volume on new and existing contracts, accretive acquisitions, and continuing to closely manage costs.
I will turn now to our operating segments. Starting first with federal solutions, where our fourth-quarter revenue increased by $280 million or 50% from the fourth quarter of 2022. This increase was driven by organic growth of 47% in the contribution from our Sealing Tech acquisition, which closed in August of 2023. Organic growth was driven primarily by the ramp up of recent contract wins and growth on existing contracts.
federal solutions' adjusted EBITDA increased by $35 million or 73% from the fourth quarter of 2022, and adjusted EBITDA margin increased 130 basis points to 9.8%. These increases were driven primarily by increased volume on new and existing contracts with effective cost controls.
For the full year, federal solutions' revenue increased by $808 million or 30% -- 36% from 2022. This increase was driven by organic growth of 25% and approximately $264 million from acquisitions. Organic growth was driven by the ramp-up of recent contract wins and growth on existing contracts. Federal solutions' adjusted EBITDA for the full year increased $90 million, were 45% from 2022, and adjusted EBITDA margin increased 60 basis points to 9.6%. These increases were driven primarily by organic operating leverage, accretive acquisitions, and [$20 million] of non-recurring incentive fees recognized in the second quarter of 2023.
Moving now to our critical infrastructure segment. Fourth-quarter revenue increased by $111 million or 21% from the fourth quarter of 2022. This increase was driven by organic growth of 20% in the inorganic revenue contribution from acquisitions. Organic growth was driven by higher volume on both Middle East and North America infrastructure programs.
Critical infrastructure's adjusted EBITDA decreased by $5 million or 10% from the fourth quarter of 2022. Adjusted EBITDA margin decreased 240 basis points to 7.0%. The adjusted EBITDA decreases were driven by the $20 million negative net impact previously discussed, partially offset by profit s from accretive organic growth on both new and existing contracts.
For the full year, critical infrastructures' revenue increased by $440 million or 22%, almost all of which was organic. Organic growth was driven by expansion in both the Middle East and North America. Critical infrastructures' adjusted EBITDA for the full year increased by $22 million or 14% from 2022, and adjusted EBITDA margin decreased 50 basis points to [72%]. The adjusted EBITDA increase was driven primarily by accretive organic growth and operating leverage. The lower margin was the result of fourth quarter's $20 million net impact from the two programs previously discussed.
Excluding the Q4 impact, critical infrastructure margins were 10.1% and 8.1% for the quarter and total year's prospectively.
Next, I'll discuss cash flow and balance sheet metrics. Our net DSO at the end of Q4 2023 was 59 days, down 10 days from the prior year period. Our fourth quarter operating cash flow totaled $190 million compared to $89 million from the prior year period. Our operating cash flow for the full year increased 72% to $400 million. Our strong cash flow was driven by improved profitability and strong collections across the portfolio.
Total year free cash flow conversion was 120%. Capital expenditures totaled $10 million in the fourth quarter of 2023 and $40 million for the full year. CapEx continues to be well controlled and remains in line with our planned spend of less than 1% of annual revenue. Our balance sheet remains strong as we ended the fourth quarter with a net debt leverage ratio of 1.0 times compared to 1.4 at the end of 2022, even after closing three acquisitions in 2023.
Our low leveraged, strong free cash flow outlook and [batch] capacity will enable us to continue to make internal investments and accretive acquisitions to support long-term growth.
Turning to bookings for the fourth quarter. Year over year, contract award activity increased 13% to $1.2 billion. On trailing 12-month basis, contract awards increased by 40% and our book-to-bill ratio was 1.1 times on an enterprise basis and in both business segments. Our book-to-bill ratio for the fourth quarter was 0.8 times.
In our critical infrastructure segment, we have achieved a quarterly book-to-bill ratio of 1.0 times or better for 13 consecutive quarters. We remain optimistic that IGA and global infrastructure investments will continue to drive demand and new business well into the future.
Our recent contract awards and backlogs to support our long-term critical infrastructure margin goal of approximately 9% by 2025. Our backlog at the end of the fourth quarter totaled $8.6 billion, up $413 million or 5% from the fourth quarter of 2022.
Next, I'll turn to our guidance. When establishing our guidance, we've contemplated key variables, which include a competitive labor market, uncertainty around domestic budgets, and challenging inflation. However, we're confident in our ability to achieve results within our improved guidance ranges given significant tailwinds, including unprecedented global infrastructure spend, a federal portfolio that's closely aligned to the national defense strategy, low recompete risk, $8.6 billion of total backlog included funded backlog of $5 billion, and $14 billion of contracts won that are not yet reflected in backlog.
For '24, we expect revenue to be between $5.8 billion and $6 billion. This represents 8% growth at the midpoint of the range, and 7% growth on an organic basis. Our adjusted EBITDA is expected to be between $505 million and $545 million, with a margin of 8.9% at the midpoint of our revenue and adjusted EBITDA guidance ranges. This represents adjusted EBITDA growth of 13% and margin expansion of approximately 40 basis points from 2023, achieving our Investor Day commitments.
The growth in adjusted EBITDA and associated margins is expected to be driven by improved program performance, accretive wins, and a continued focus on operating leverage. Our cash flow from operating activities, which is expected to be between $350 million and $410 million. At the midpoint of the guidance range, we expect free cash flow conversion to be approximately 100% of adjusted net income.
2024 cash flow is expected to be down from 2023, primarily due to the exceptional fourth quarter that accelerated approximately $30 million in receipts from 2024.
Our other key assumptions in connection with our 2024 guidance and our quarterly cadence are outlined on slide 15 in today's PowerPoint presentation located on our Investor Relations website. As Carey mentioned, we are increasing the long-term targets we provided at our March 2023 Investor Day. At that time, we expect the total revenue growth of 4% to 6% and organic growth of 3% to 5%. We now believe that we can achieve organic revenue growth of mid-single digits or better through 2025.
With performance in 2023, a strong outlook for 2024, we are raising our revenue growth targets of a total revenue base that is $1.2 billion higher than it was at the end of 2022.
In addition, we continue to expect an average of 20 to 30 basis points to margin expansion each year through 2025 and a free cash flow conversion rate of 100% or more of adjusted net income. These targets indicate we expect total revenue to exceed 6 billion and adjusted EBITDA margin to be over 9% by the end of 2025. These implied targets indicate adjusted EBITDA growth is expected to outpace total revenue growth through 2025.
We expect to supplement organic growth with two to three accretive acquisitions per year to further drive shareholder value. In summary, we reported exceptional results from the fourth quarter and full year. I'm confident in our ability to achieve results within our 2024 guidance ranges. We are operating in well-funded markets, had a great team that is executing at a high level, and I believe we're making the right organic and inorganic investments to continue to drive growth and margin expansion into the business.
With that, I'll turn the call back over to Carey.
Carey Smith
Thank you, Matt. I'm very pleased with the continued strong performance of our company. We delivered record fourth-quarter and full-year results for total revenue, organic revenue growth, adjusted EBITDA, operating cash flow, and contract awards. In addition, we're executing on our strategic M&A program, which driving additional growth into our business.
Our team is delivering consistent results, and we're benefiting from tailwinds in each segment. We expect our momentum to continue, given our portfolio is well aligned to important macroenvironment trends into well-funded segments and six growing and enduring markets.
With that, we will now open the line questions.
Question and Answer Session
Operator
(Operator Instructions) Sheila Kahyaoglu, Jefferies.
Sheila Kahyaoglu
Good morning, everyone. Thank you so much. Matt and Carey, happy Valentines Day. I just wanted to say. I think we're all pretty in love with these results and what you've done with Parsons. So congratulations. I mean, it's pretty phenomenal.
So I guess my first question's related to that. You started off '23 guiding for organic growth up [for]. You closed up 23% and you accelerated into the year, which is kind of amazing. So I guess, what unlocks that? Can you talk about was it hiring? Was that just award wins? New business? And how do you expect that to with progress? Obviously, you've raised your long-term targets.
Carey Smith
Well, thank you, Sheila, for your questions. Happy Valentine's Day to you as well. So I would say hiring and retention have continued to be strong. Our consistent trailing 12-month book-to-bill of greater than [1.0] has helped us win new programs. We had record win rates to share at 66%, with 93% of recompetes. We've secured all four of our major recompetes that are $2 billion programs. And I would say business development is hitting it across the board on all cylinders.
What I'm probably most proud of is all four business units delivered double-digit organic growth, so it's not one business unit driving Parsons. All four business units are [delever ed].
Sheila Kahyaoglu
Maybe we could delve into the critical infrastructure growth and just the segmentation on a regional basis. It looks like Europe, Middle East, Africa are growing 2x, North America. So can you just talk about the balance of those two in the high single-digit growth for 2024? How do you see it? How much is locked in, whether it's in the backlog or the unbooked pipeline?
Carey Smith
Yes. We're really pleased with the Middle East growth being over 30% this year. We had some very strong wins and large programs, particularly in Saudi Arabia, that occurred, but also doing well in the UAE. North America is also doing extremely well and had strong organic growth. And if you look at that, it was 16%. So both organizations are doing well.
I would say North America is going to continue to speed up because we haven't hit the peak yet on the infrastructure investment and Jobs Act. We expect that to be around the 2027 timeframe. But that said, the Middle East also that growth is expected to peak somewhere between 2028 and '30. So the nice thing is we've got strong tailwinds in both of our [NG] and geographies for a long foreseeable future.
Operator
Tobey Sommer, Truist Securities.
Jasper Bibb
Hey, good morning. This is Jasper Bibb on for Tobey. I guess just following up on a negative $20 million from the [NCI] segment, can you update us how much of that risk your legacy work is still in the segment today? And with a near 10% margin. Excluding those adjustments, how should we think about the go-forward margin profile as that business comes out of the portfolio?
Carey Smith
Sure. Thanks for the question. So this was not one of the two legacy programs that you've heard us refer to previously. Fortunately, we had indicated that one of those programs was just going to wrap up the first quarter of this year, which it did. That is going to present a $18 million on tailwind for us as we enter the share because we had $18 million write-off on that particular program last year.
The second legacy program is still on track to complete in the third quarter of this year, and that program is 90% and exceeded some recent technical milestones. The program that we had, the $20 million impact or the $58 million write-down was due to supply chain impacts from material procurement. It was a job that have been bid back in 2019 prior to COVID. So we got initial quotes at that time.
Once we get into design several years later and we went back and we refresh those quotes, we had less supplier availability and those suppliers, prices have gone up. The good news is that this is kind of one-off, I'm going to stay, within our portfolio because we stopped bidding this type of work years ago. So we don't have other large contracts that have a big majority of material pass through.
I'm really pleased that even with this impact, the great job that we've done expanding margins, we were up 13 basis points for the year. We grew EBITDA dollars at 32% with revenue up 30%. So EBITDA is growing faster. And as we looked at 2024, we're going to be expanding our margins by 40 basis points.
Matthew Ofilos
Jasper, I'd just add relative to critical infrastructure specifically, the total year was about 7.2% within the business. We're expecting about 8.5% in 2024. Federal will still be in kind of a low 9%, [or 9.2%]. And that's how we get to the [8%, 9%] midpoint.
Carey and I have talked long term that by 2025, our goals have both segments operating over 9. and a lot of the new work that we're bidding, as we've mentioned, is trending double digit. So really positive about the long-term projections for critical infrastructure.
Jasper Bibb
Thanks. And then the organic growth is obviously really impressive this quarter. But ramp significantly ahead of your backlog growth from a book to bill. So how should we think about the ability of the backlog? What you're seeing in the bid pipeline, the awards you won after the quarter that support further growth in '24 and '25?
Carey Smith
Yeah. So we're pleased that we were able to win the 15 awards greater than $100 million. And as we announced, we've had two greater than $100 million already as we go into this year. The bid pipeline is very robust. It's the highest it's ever been for our business, such at $58 billion. Other than $58 billion, we have 110 awards that are greater than $100 million.
We also have a weighting notice of award, $4 billion. And within there, we have eight programs greater than $100 million. And then we've talked about the $14 billion of unbooked backlog. So that's basically comprised of contracts. They have option years or unbooked ceiling, and we're confident on good portion, and that being able to convert over the next three years.
Jasper Bibb
Got it. A last question for me. I just wanted to ask about M&A appetite and the size of deals you might be looking at. I guess we did notice the $10 million in transaction rather expensive [guidance]. So just any color on what that might be related to.
Matthew Ofilos
Yeah, I would say the overall pipeline for M&A remains strong. I think we're -- withanything that's in the guide is related to prior transactions. So we as we mentioned, we closed the I.S. Engineers deal in Q4. And so again, the M&A pipeline is quite strong. We feel good about -- we've closed three transactions in 2023. And our goal is two to three in 2024 as well.
Carey Smith
And I'll just add to that. So we're looking at both federal and critical infrastructure. The size of the deals will continue to be around what we've done the past. We generally look at companies that are between about $105 million, $100 million annual revenue.
But as you noted, we did buy I.S. Engineers for $10 million. And the reason for that is that it was located in a key state that's going to have a lot of potential growth. And what we intend to see is smaller deals on the critical infrastructure side versus the federal side of the house.
We've been very selective. We're going to continue to keep our high bar of companies growing greater than 10% top line, greater than 10% EBITDA margin. And we're also looking for companies that have technology differentiation, but a good pipeline.
Operator
Bert Subin, Stifel.
Bert Subin
Hey, good morning. I guess I'll echo everyone's thought. It's just amazing results.
Carey Smith
Thank you, Bert.
Matthew Ofilos
Thanks, Bert.
Bert Subin
So, Carey, maybe just a follow-up from earlier question. How do you do you think you keep momentum going in federal solutions? I mean, we just grew essentially 4,000 basis points above the industry in the fourth quarter. Just curious how much of that was driven by unit specific contracts being full venture or additional work with the FA? And then how good is your visibility as we think to '24, '25? I guess it's pretty good since you're updating those longer-term targets.
Carey Smith
Yes. So I'll take the second part first. Our visibility is very good. The good news, too, we have very low recompete, which we mentioned on the call. But it's less than 5% as we go into this year. We also have that $14 billion of unbooked contracts. So the visibility and line of sight to that transitioning is good over the next three years. We anticipate a roughly 50% to transition.
How do we keep the momentum going is we continue to keep laser focus on our six core markets. Those markets are all growing between 5% to 12% compound annual growth rate. Our goal has been to be differentiated and be a top player in each of those market areas.
And one thing I was happy about when you look at our wins across the year and those 15, we won in almost every single area. If you look at environmental remediation, for example, we won work and the mine jobs. We expanded our presence in army ammunition, plant modernization. If you look at cybersecurity, we've been very, very strong with cyber command as well as the GSA job. And doing with [Department of State] has been very good.Also in work [Endo Paycom], expanding our footprint there was [housing].
If you look over on the infrastructure side, in transportation, we were awarded what at the time was our biggest design jobs since IPO with JFK highways. We just surpassed that with IT infrastructure job that I announced on the call today, which will now be our new biggest design job that we've had.
And then finally, urban development. The team over in the Middle East has just done an amazing job of securing our position on all [bigger] projects. And the fact that we're [naming], I see a peak there until later in 2020 to 2030 timeframe. I think we've got a lot of momentum in the business.
Bert Subin
Maybe just as my follow-up, Carey. You talked about the Middle East there. It's clearly been an engine for pretty [subdued] growth. We saw a slowdown of the growth basis. it is still very elevated. As we look forward, can you just talk about I guess what the risks are in the region? Are you seeing any spillover from conflict and Red Sea, and Israel [loss]? Or I guess as we think beyond that, is there a geographic dispersion you expect? I mean, it sounds like [soggy], but really strong. Are you seeing strength of UAE? Are you seeing a rebound in [cutter]? Just curious how the Middle East is shaking out.
Carey Smith
Yes. So from a risk perspective, the conflicts really dealt pertain to the type of work we do because we're really doing infrastructure. I would call it helping Saudi really build out their infrastructure, whether it's transportation infrastructure, whether it's new industrial cities, whether it's new entertainment and tourism.
That building is just going on across the country and will continue for a long time. It's great for their -- all the people that live there because they'll have places to go for entertainment. Their education systems getting improved. Their healthcare is getting improved. So I'd say that's terrific.
On the conflict side, where we would see potential opportunity is in our federal solutions business because of the type of areas we play in. Whether that's cybersecurity, missile defense, and intelligence type of work. We also do some RF emulator projects that we've seen deployed.
Our geographic dispersion. We are the largest and Saudi Arabia, about 60%, 65% of our business is there. That's also been our fastest-growing, followed by the UAE, which has not had strong growth. UAE's focus has been on mixed-use developments and continuing to build out whether it's Dubai or Abu Dhabi, which where most of our work there is. And we did recently the UAE World Expo.
In Qatar, we were heavily involved in the World Cup. We did that traffic management system for that. We also did they [Lusao City], which we were recognized as an outstanding consultant for our performance there. But I would say Qatar will probably out of the three of those be the slowest, with Saudi being the fastest, followed by UAE.
Bert Subin
Thanks, Carey. I guess, Matt, just as a sort of a last follow-up. On the cash side, it sounds like generation looks really good. And talking more like two to three deals a year versus maybe wanted to deployment either sort of willing to wait until you guys buy the next deal.
Matthew Ofilos
Yeah, I think that's right, Bert. But obviously, we have the share buyback program that's kind of nominal. We did about $11 million with our share buyback in 2023. But definitely, the focus is on M&A. And to your point, team has done an amazing job with the $400 million of cash for the year, just focused on working capital improvements. And so the cash is generating and we're really achieving critical milestones.
So really excited about the cash position. The 1.0 leverage puts us in a great place to keep pushing deals. I'd say the transition from kind of a one to two deals to two to three is a mix of going from kind of a heavier federal to a mix of federal N CI. Where the CI deals, as Carey mentioned, are a little bit smaller. So we have capacity to just kind of get to the two to three.
Carey Smith
And then M&A really helps our momentum as well , whether it's if I look at the [Sealing Tech] really expanded our presence in defense of cyber. We were strong in offensive. Now, we can cover full spectrum cyber operations. I talked about I.S. Engineers, expanding our presence in Texas. The two of us together can move up the value chain and bid and win larger jobs.
And then IP cases kind of nice at the intersection between federal and critical structure, providing cyber compliance for on energy and water companies. So those -- all of those acquisitions as well as the ones that we've done in prior years are healthy momentum.

Andrew Wittmann, Baird.
Andrew Wittmann
Great. Good morning. Thanks for taking my question. I think I might just have one question today. As I look at the capital structure, you got this $400 million convertible note out there. It fully hedged with the bond hedge that you've got on it. And it looks like the conditions to convert that to equity have been met with the trading performance of the stock here in the last several months.
So I guess my question is, what are you going to do about $400 million face that's totally hedged out? Like I guess is it fair to figure that is basically kind of gone or like not the balance sheet because you've got to hedge that takes out the dilution that would result if you converted it? And what do you expect to do in practical sense with this? And if anything at all?
Matthew Ofilos
Andy, thanks for the question. I would say the we obviously look to the balance sheet constantly. We want to make sure that we're capable of continuing to do the M&A. The convert that we have in place has been a great deal for both us and kind of the convert holders as the stock has performed so well.
So all in all, we continue to look at it. I would say it remains on the balance sheet. It is [local] current until August of this year. But we're continuing to look at options as we go forward. So no solid plan yet, but always looking at opportunities.

Alex Dwyer, KeyBanc Capital Markets.

So I wanted to ask about the organic revenue growth guidance of 7% this year. How that splits between the segments this year? And if we can parse through the different assumptions from hiring and retention to win rate to the ramp up for contracts? And if there's upside to the 7% revenue guide, where do you think we're most likely to see this upside come from?
Carey Smith
Yeah. So the 7% is roughly equal with federal being a little bit higher growth. And as far as upside, I would say across the portfolio, again, because of if you look at the 15 wins we've had in 2023 that we announced in this year so far, [greater than 102 that] we just it's across the board in all six of those end market areas. They really affects all four of the business units.
Matthew Ofilos
Then I would say, it's kind of get to the high end. As Carey mentioned, I think in her script a little bit around the labor markets. I think the US budget obviously getting deal done that we create. And so kind of those, those are the things that we're working through in terms of trying to get from the midpoint of the high end.
Alex Dwyer
Got it. Thanks. And then the critical infrastructure backlog continues to remain strong. But I wanted to ask about Federal Solutions with a 0.7 book-to-bill this quarter. How much of that was the impact of the continued CRs? And should we continue to expect this segment to remain below 1 time until the government gets a full budget?
Carey Smith
So I would say for Q4 is always slight for federal government services. Third quarter is usually kind of a peak, but I would say the trailing 12 months as we look at what's very important, and that's been a 1.1. And so I think our federal business has been delivering quite fine. On that CR, I know I don't expect that to drive being below 1.0 times. And the reason I don't is because we've already won a lot of work that $14 billion and the majority of that is, in fact, role that we have been booked yet that we can still convert. We also -- by the way, one other variable, we've got 59% funded backlog, which is very high.
Operator
Louie DiPalma, William Blair.
Louie DiPalma
Are the exit or ceiling pack and [IPE] acquisitions performing significantly better than their revenue run rate prior to being acquired? And when Parsons integrate these assets, are you able to unlock significant cross-selling revenue synergies that make the returns much more attractive than the original multiple may suggest?
Carey Smith
Yes. So I would say [exited] has certainly been outperforming on our revenue front. Sealing Tech has really recent, but we do expect here they're going to deliver very strong performance. I'll talk about that a minute. And IPE is on track with our expectations.
We do get the value as you're pointing out, Louie, from the cross selling. We haven't factored in revenue or cost synergies as we've made these acquisitions. So anything that we get is kind of above and beyond. Great example would be IPEs. They have a book of customers, hundreds of customers in the utility in the water space. So in addition to selling those customers, their capabilities, we can also solve a broader persons capabilities in those market areas.
Likewise, we can take their products to our current utility and water, wastewater customers and sell that. We've seen synergies already even between Sealing Tech and IPEs and coming up with a new product line offering on called Cyber Escape. And we're going to be putting IPEs capabilities on the fly away cuts at Sealing Tech, such how quickly we do the integration and we drive synergies. But that's definitely a big factor helping our momentum.
Louie DiPalma
Great. And another one, Parsons has been particularly strong with capturing classified fiber contracts over the past year. In general, what is driving that strength? And are these cyber contracts or some of them from affiliated with the Geopolit Ical conflicts in Europe, the Middle East, and Asia? And in general, what is Parsons presence with Endo Paycom mix?
Carey Smith
Okay. So I'll take the first one. What's driving the cyber? I would say first for one of the leaders in offense of cyber, and that comprise about 75% of our business on. We have in-depth relationships across the Department of Defense military services as well as the intelligence community and customers like cyber command. So we've been able to get a very strong position. We've done work for them for a long time. They know they can count on us, particularly in a timing issue as you mentioned such as the complex affiliation.
I can't comment on too much more on that nature. Endo Paycom, we have efforts underway, we've been on Guam for over three decades supporting public works. That's through our critical infrastructure group. We also are on Guam supporting defense of Guam through the missile -- for the missile defense [change shape] through our teams contract.
We're in [Cluj line] Island. We built the Cluj line airfield. We're also just recently won the Cluj line housing, and we're looking for continued expansion there. Particularly that budget cut increased from $9.1 billion over $14 billion in the [NDAA] so that's going to be a big focus area.
And then on our defense and intelligence side, we have over 100 folks located out in Hawaii that are working in cyber and intelligence type of work.
Louie DiPalma
And one for Matt. Your acquisitions, are they typically margin accretive and you can't forecast that you would expect to have three acquisitions per year or so in general. Should these acquisitions being one of the drivers for your continued margin expansion that you've guided to and are about 2025 outlook?
Matthew Ofilos
Yes, absolutely. Louie. We target them adjusted EBITDA of 10% or better. And so all these companies are performing well. I'd like to say that we like to buy companies that are doing well and bring them in and have them do better as part of Parsons versus kind of betting on the come, whether it's on revenue growth or margin. So yeah, absolutely. Each one of these acquisitions are expect it to be accretive in a very short term and have strong cash flow as well.
Operator
Mariana Pérez Mora, Bank of America.
Samantha Sparrow
Hi, this is Samantha Sparrow on from Mariana, if I'm incorrect, but I just wanted to ask about labor and hiring and kind of what you're seeing on these, what you just mentioned the classified contracts on kind of getting those certifications. Are you seeing still a strong for like a long wait list there?
Carey Smith
Yes. So overall and labor and hiring, and we're doing very well. Obviously, that's been critical to driving our organic growth. We've seen our retention improve. In fact, it improved by over [8%] year to year, which is very strong. And we were already ahead of PWC industry benchmarks in that area.
As far as classified contracts the clearance processing move to of DCSA back in 2019. And when it did, they were able to drop the backlog. And I must say, it was close to 75%. And they also sped up the clearance processing time for secret and top secret, which has really helped us. Classified areas always going to be the most difficult though, to higher, but we've seen some improvement in recent years.
Samantha Sparrow
Great. And then on these programs that you have, the $14 billion of unbooked. Would those require more hiring to keep up with? Minority [time] hiring ahead of that? Or do you have the people in place already?
Carey Smith
Yes. So it's a mix, so I'll put them into two categories. When you looked at it, about half that $14 billion of unbooked as option years. So those would be current programs that were performing and we'll get follow-on options. In general, most of those would have the people performing their contract today. There might be some increased or surge scope as you go into the options. But generally, those would be onboard.
The ones where we would get additional labor is the ones that are unbooked ceiling. So a case example of that would be we won an air-based air defense program in Europe. So that has just shy of $1 billion ceiling. So we book that as we get task orders, and those task orders represent all new work. So it's about 50-50.
Operator
That is all the time we have for questions today. I would now like to turn the call back to Dave for closing remarks.
