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 of 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 growth 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 our repeats. Also, our exquisite federal solutions portfolio is aligned with national security 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 and new work in support of the United States government. This five-year contract 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 a United States customer. We booked $73 million on this contract in the fourth quarter. We were also awarded prime positions 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 Agency cleanup projects. We continue to win significant environmental remediation projects. During the fourth quarter, we also completed a comprehensive assessment, investigation, and treatment of PFAS for a major Fortune 100 industrial client. 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 of a multidisciplinary PFAS team. The 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. And this contract has an estimated ceiling 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 repeat 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 IS 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 IS Engineers marks our third acquisition in 2023, which includes two acquisitions in critical infrastructure and one in federal solutions. In addition to bolstering our critical infrastructure portfolio through strategic acquisitions, we strengthened and reorganized this segment to better align with our customers, geographies, and end markets. and better position Parsons to capitalize on the unprecedented global infrastructure spent. 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 Corporate Equality Index for active support and inclusion of the LGBTQ plus 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 increases 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 in two high growth and complementary segments that continue to experience significant tailwinds. Starting with federal solutions, the proposed defense budget supports an $886 billion top-line budget, which is 3% higher overall than 2023. However, the Parson's 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 remains strong in all three geographies where Parsons operates, the United States, Canada, and the Middle East. We are leveraging our core competencies in engineering design, program management, and owner's representative to win and deliver on large, complex programs. As an industry leader in applying digital transformation to infrastructure, we look forward to continuing to transform this industry. Given our strong performance and 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 off a total revenue base that is $1.2 billion higher than it was at the end of 2022. In addition, we expect average 20 to 30 basis points of margin expansion each year through 2025 and a free cash flow conversion rate of 100% or more of 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?

speaker
Dave

Thank you, Carrie. As Carrie indicated, our fourth quarter and fiscal year of 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 a rail and transit project, for which we realized a $38 million favorable impact to fourth quarter adjusted EBITDA. On the second program, within equity and earnings, we took a $58 million adjusted EBITDA charge. The impact was the result of supply chain challenges identified during the procurement of materials. Normalized margins excluding these 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. The 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 driven primarily by increased volume on new and existing contracts, accretive acquisitions, and continuing to closely manage costs. I'll turn now to our operating segments, starting first with Federal Solutions, where fourth quarter revenue increased by $280 million, or 50% from the fourth quarter of 2022. This increase was driven by organic growth of 47% and the contribution from our ceiling 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 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, or 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% and the inorganic revenue contribution from acquisitions. Organic growth was driven by higher volume on both Middle East and North America infrastructure programs. Critical infrastructure 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 profits from accretive organic growth on both new and existing contracts. For the full year, critical infrastructure's 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 infrastructure's adjusted EBITDA for the full year increased by $22 million, or 14% from 2022, and adjusted EBITDA margin decreased 50 basis points to 7.2%. The adjusted EBITDA increase was driven primarily by accretive organic growth and operating leverage. The lower margin was the result of fourth quarter $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 years, respectively. 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 in the prior year period. Our operating cash flow for the full year increased 72% to $408 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 leverage, strong free cash flow outlook, and balance sheet 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 a 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 IJA and global infrastructure investments will continue to drive demand and new business well into the future. Our recent contract awards and backlog 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 is closely aligned to the national defense strategy, low recompete risk, $8.6 billion of total backlog included fund backlog of $5 billion, and $14 billion of contracts won that are not yet reflected in backlog. For 2024, we expect revenue to be between $5.8 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 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 activity is expected to be between $350 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 Kerry mentioned, we're increasing the long-term targets we provided at our March 2023 investor day. At that time, we expected 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 off 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 of 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 our organic growth with two to three accretive acquisitions per year to further drive shareholder value. In summary, we've reported exceptional results from the fourth quarter in a full year, and I'm confident in our ability to achieve results within our 2024 guidance ranges. We are operating in well-funded markets, have a great team that is executing at a high level, and I believe we are 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 Carrie.

speaker
Carrie 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 is 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 macro environment trends in two well-funded segments in six growing and enduring markets. With that, we will now open the line for questions.

speaker
Operator

Thank you. As a reminder, to ask a question, please press star 11 on your telephone and wait for your name to be announced. To withdraw your question, please press star 11 again. Please stand by while we compile the Q&A roster. The first question comes from Sheila Kayaglu with Jeffries. Your line is open.

speaker
Sheila Kayaglu

Good morning, everyone. Thank you so much. Happy Valentine's Day. I just want 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 is related to that. You know, you started off 23 years. guiding for organic growth up four. You closed up 23% and you accelerated into the year, which is kind of amazing. So I guess, what unlocked that? Can you talk about, was it hiring? Was it just award wins, new business? And how do you expect that to progress? Obviously, you've raised your long-term target.

speaker
Carrie Smith

Well, thank you, Shield, for the question. 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 this year at 66% with 93% of re-competes. We've secured all four of our major re-competes 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 deliver double-digit organic growth. So it's not one business unit driving persons. All four business units are delivering.

speaker
Sheila Kayaglu

Maybe if 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 implied for 2024? How do you see it? How much is locked in, whether it's in the backlog or the unbooked pipeline?

speaker
Carrie Smith

Yes, so we're really pleased with the Middle East growth being over 30% this year. We had some very strong wins in 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 with that said, the Middle East also, that growth is expected to peak somewhere between 2028 and 2030. So the nice thing is we've got strong tailwinds in both of our angiographies for the long foreseeable future.

speaker
Andy

Great, thank you.

speaker
Carrie Smith

Thanks, Sheila.

speaker
Operator

Please stand by for the next question. The next question comes from Toby Summer with Truist Securities. Your line is open.

speaker
spk11

Hey, good morning. This is Jasper Bibb on for Toby. I guess just following up on the negative 20 million adjustment in the CI segment, can you update us how much of that riskier 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?

speaker
Carrie 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 going to wrap up the first quarter of this year, which it did. That is going to send a $18 million tailwind for us as we enter this year because we had $18 million right 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's 90% done and it 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 had been bid back in 2019 prior to COVID. So we got initial quotes at that time. We completed the design several years later, and we went back and we refreshed those quotes. We had less supplier availability, and those suppliers' prices have gone up. The good news is that this is kind of a one-off, I'm going to say, 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 look to 2024, we're going to be expanding our margins by 40 basis points.

speaker
Dave

Yeah, Jasper, I'd just add relative to critical infrastructure specifically, you know, the total year was about 7.2% within that business. We're expecting about 8.5% in 2024. Federal will still be in kind of the low nines, called 9.2%, and that's how we get to the 8.9% midpoint. Carrie and I have talked long term that by 2025, our goal is to have both segments operating over 9%. And a lot of the new work that we're bidding, as we've mentioned, is trending toward double digits. So really positive about the long-term projections for critical infrastructure.

speaker
spk09

Thanks.

speaker
spk11

And then the organic growth is obviously really impressive this quarter, but ran significantly ahead of your backlog growth in the book to bill. So just how should we think about the ability of the backlog, what you're seeing in the bid pipeline, some of the awards you won after the quarter to support further growth in 24 and 25?

speaker
Carrie Smith

Yes, 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. It's at $58 billion. Out of the $58 billion, we have 110 awards that are greater than $100 million. We also have a waiting 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 that have option years or unbooked ceiling. And we're confident on a good portion of that being able to convert over the next three years.

speaker
spk11

Got it. 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 and other expense in the guide.

speaker
spk13

So just any color on what that might be related to.

speaker
Dave

Yeah, I would say the overall pipeline for M&A remains strong. I think we're, you know, anything that's in the guide is related to prior transactions. So, as we mentioned, we closed the IS engineers deal in Q4. And so, again, the M&A pipeline is quite strong. We feel good about we closed three transactions in 2023. Our goal is two to three in 2024 as well.

speaker
Carrie 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 in the past. We generally look at companies that are between about $100 million and $500 million annual revenue. But as you noted, we did buy IS 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 you tend 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.

speaker
spk10

Thank you for taking the questions.

speaker
Carrie Smith

Thanks, Jasper.

speaker
Operator

Please stand by for the next question. The next question comes from Bert Subin with Stiefel. Your line is now open.

speaker
Bert Subin

Hey, good morning. I guess I'll echo everyone's thoughts. I mean, just amazing results.

speaker
spk24

Thank you, Bert. Thanks, Bert.

speaker
Bert Subin

So, Kerry, maybe just to follow up to an earlier question, you know, how do you think you keep momentum going in federal solutions? I mean, you just grew essentially 4,000 basis points above the industry in the fourth quarter. And I'm just curious how much of that was driven by, you know, specific contracts, be it Bold Venture or additional work with the FAA. 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.

speaker
Carrie Smith

Yes. So to take the second part first, our visibility is very good. The good news, too, we have very low repeat, 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 roughly 50% of that to transition. How do we keep the momentum going is continue to keep a laser focus on our six core end markets. Those markets are all growing between 5% to 12% compound annual growth rate. Our goal has been to be differentiated, 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 in 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. If you look at critical infrastructure protection, the work that we've been doing with Department of State has been very good. Also one work in Indo-PACOM, expanding our footprint there with Kwajalein housing. If you look over on the infrastructure side and transportation, we were awarded what at the time was our biggest design job since IPO with JFK Highways. We just surpassed that with the 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 the GIGA projects And the fact that we're not even going to see a peak there until later, you know, 2028 to 2030 timeframe, I think we've got a lot of momentum in the business.

speaker
Bert Subin

Maybe just as my follow-up, Carrie, you talked about the Middle East there. It's clearly been an engine for pretty significant growth. We saw it slow down on the growth basis, but 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 just from conflict and Red Sea? you know, in Israel, Hamas, or I guess as we think beyond that, you know, is there a geographic dispersion you expect? I mean, it sounds like Saudi's been really strong. Are you seeing strength in the UAE? Are you seeing a rebound in Qatar? Just curious how the Middle East is shaking out.

speaker
Carrie Smith

Yes, so from a risk perspective, the conflicts really don't pertain to the type of work we do because we're really doing infrastructure work. 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 all the people that live there because they'll have places to go for entertainment. Their education system is 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, intelligence type of work. We also do some RF emulator projects that we've seen deployed. Our geographic dispersion, we are the largest in Saudi Arabia, about 60%, 65% of our business is there. That's also been our fastest growing, followed by the UAE, which has 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 is 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 the traffic management system for that. We also did the Lausanne 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.

speaker
Bert Subin

And, Carrie, I guess, Matt, just as sort of a last follow-up, on the cash side, you know, it sounds like Generation looks really good. And, you know, talking more like two to three deals a year versus maybe one to two. I guess in the meantime, how are you thinking about capital deployment? Are you just sort of willing to wait until you guys find the next deal?

speaker
Dave

Yeah, I think that's right, Bert. You know, obviously we have the share buyback program that's kind of nominal. We did about $11 million worth of share buyback in 2023, but definitely the focus is on M&A. And to your point, you know, the team has done an amazing job with the $100 million in op 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 the one to two deals to two to three is a mix of, you know, going from kind of a heavier federal to a mix of federal and CI, where the CI deals, as Kerry mentioned, are a little bit smaller. So we have capacity to kind of get to the two to three.

speaker
Carrie Smith

And that M&A really helps our momentum as well. You know, whether it's, if I look at the three recent deals, ceiling tech really expanded our presence in defensive cyber. We were strong in offensive. Now we can cover full-spectrum cyber operations. I talked about ISN 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 Keys is kind of nice at the intersection between federal and critical infrastructure, providing cyber compliance for energy and water companies. So all those acquisitions, as well as the ones that we've done in prior years, are helping momentum.

speaker
IP Keys

Great. Thank you so much, Ben and Kerry.

speaker
Operator

Thank you. Please stand by for the next question. The next question comes from Andrew Whitman with Bayard. Your line is open.

speaker
Andrew Whitman

Great. Good morning. Thanks for taking my question. I think I might just have one question today, and it's for Matt. As I look at the capital structure, you've got this $400 million convertible note out there. It's 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 thought or my question is, what are you going to do about this $400 million face that's totally hedged out? Like, I guess, is it fair to think of that as basically kind of gone or like not on the balance sheet because you've got the 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, if anything at all?

speaker
Dave

Yeah, I'd say, Andy, thanks for the question. I would say we obviously look at 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, you know, we continue to look at it. I would say that it remains on the balance sheet. It won't go current until August of this year. But we're continuing to look at options, you know, as we go forward. So no solid plan yet, but always looking at opportunities. Okay. Thank you.

speaker
Andy

Thanks, Andy. Thanks, Andy.

speaker
Operator

Please stand by for the next question. The next question comes from Alex Dwyer with KeyBank Capital Markets. Your line is open.

speaker
Alex Dwyer

Hi, team. Congrats on a great quarter.

speaker
spk24

Thank you, Alex. Thanks, Alex.

speaker
Alex Dwyer

So I wanted to ask about the organic revenue growth guide 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 of contracts. And if there's upside to this 7% revenue guide, where do you think we're most likely to see this upside come from?

speaker
Carrie 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 If you look at the 15 wins we've had in 2023, the 100 and the two that we just announced this year so far, it's across the board in all six of those end market areas. So it really affects all four of the business units.

speaker
Dave

Yeah, and I would say, you know, to kind of get to the high end, as Carrie mentioned, I think in her script, a little bit around, you know, labor markets. I think the U.S. budget, obviously, getting a deal done would be great. And so kind of those are the things that we're looking through in terms of trying to get from the midpoint to the high end.

speaker
Alex Dwyer

Got it. Thanks. And then the critical infrastructure backlog continues to remain strong, but I wanted to ask about federal solutions with the 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 one times until – the government gets a full budget?

speaker
Carrie Smith

So I would say first, fourth quarter is always late for federal government services. Third quarter is usually kind of a peak. But I would say the trailing 12 months is what we look at, which is very important, and that's been a 1.1. And so I think our federal business has been delivering quite fine. On the CR, no, I don't expect that to drive being below a 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 federal that we haven't 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.

speaker
Alex Dwyer

Thank you. Very helpful. Appreciate the thoughts.

speaker
Operator

Thanks, Alex. Thanks, Alex. As a reminder to ask a question, Please press star one one on your telephone and wait for your name to be announced. One moment for our next question. The next question comes from Louie De Palma with William Blair. Your line is open.

speaker
Alex

Carrie, Matt, and Dave, good morning and great fourth quarter. You're setting the bar very high.

speaker
Matt

Thank you, Louie. Thanks, Louie.

speaker
Alex

Are the Exitor ceiling tech and IP keys acquisitions performing significantly better than their revenue run rates prior to being acquired? And when Parsons integrates 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?

speaker
Carrie Smith

Yes, so I would say ExaTor has certainly been outperforming on a revenue front. Ceiling Tech is really recent, but we do expect, you know, they're going to deliver a very strong performance. I'll talk about that in a minute. And IP Keys is on track with our expectations. We do get the value, as you're pointing out, Louis, 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 that. Great example would be IP Keys. They have a book of customers, hundreds of customers, in the utility and the water space. So in addition to selling those customers their capabilities, we can also sell the broader person's 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 Ceiling Tech and IP Keys and coming up with a new product line offering called Cyberscape, and we're going to be putting IP Keys capabilities on the fly awake at Ceiling Tech. So that's how quickly we do the integration and we drive synergies. But that's definitely a big factor helping our momentum.

speaker
Alex

Great. And another one, Parsons has been particularly strong with capturing customers classified cyber contracts over the past year. What is, in general, what is driving that strength? And are these cyber contracts or some of them affiliated with the geopolitical conflicts in Europe, the Middle East, and Asia? And in general, what is Parsons' presence with the Indo-PATCOM things?

speaker
Carrie Smith

Okay, so take the first one. What's driving the cyber? I would say, first, we're one of the leaders in offensive cyber, and that comprised about 75% of our business. 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 time of need, as you mentioned, such as the conflict affiliation. I can't comment too much more on that in depth just due to the classification nature. In the Indo-PACOM, we have several 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 for the Missile Defense Agency through our team's contracts. We're on Kwajalein Island. We built the Kwajalein Airfield. We're also just recently won the Kwajalein Housing, and we're looking for continued expansion there. Particularly, that budget got increased from $9.1 billion to 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 on cyber and intelligence type of work.

speaker
Alex

Great. And one for Matt. Are your acquisitions, are they typically margin accretive? And you just forecast that you would expect two to three acquisitions per year. And so, in general, should these acquisitions be one of the drivers for your continued margin expansion that you've guided to as part of that 2025 outlook?

speaker
Dave

Yeah, absolutely, Louie. We target adjusted EBITDA of 10% or better, and so all these companies are performing well. I 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 expected to be accretive in a very short term and have strong cash flow as well.

speaker
Louie

Excellent. Thanks, everyone.

speaker
Operator

Thanks, Louie. One moment for our next question. The next question comes from Mariana Perez-Mora with Bank of America. Your line is open.

speaker
Louie

Hi, this is Samantha Styro on for Mariana. Hi, 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 kind of getting those certifications, are you seeing still a strong or like a long wait list there?

speaker
Carrie Smith

Yeah, so overall in labor and hiring, 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 a percent 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 moved to DCSA back in 2019, and when it did, they were able to drop the backlog, and I want to 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 area is always going to be the most difficult, though, to hire, but we've seen some improvement in recent years.

speaker
Louie

Great. And then on these programs that you have the $14 billion of unbooked, would those require more hiring to keep up with? And are you kind of hiring ahead of that? Or do you have the people in place already?

speaker
Carrie Smith

Yes, so it's a mix. And I'll put them into two categories. When you look at it, about half that $14 billion of unbooked is option years. So those would be current programs that we're performing and we'll get follow-on options. In general, most of those would have the people performing the contract today. There might be some increased or surged scope as you go into the options, but generally those would be on board. The ones where we would get additional labor is the ones that are unbooked ceiling. So an example of that would be we won an air-based air defense program in Europe, and so that has just shy of a billion-dollar ceiling. So we book that as we get task orders, and those task orders represent all new work. So it's about 50-50. Got it.

speaker
Matt

speaker
Carrie 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 of 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 growth 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 our repeats. Also, our exquisite federal solutions portfolio is aligned with national security 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 and new work in support of the United States government. This five-year contract is 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 a United States customer. We booked $73 million on this contract in the fourth quarter. We were also awarded prime positions 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 Agency cleanup projects. We continue to win significant environmental remediation projects. During the fourth quarter, we also completed a comprehensive assessment, investigation, and treatment of PFAS for a major Fortune 100 industrial client. 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 of a multidisciplinary PFAS team. The 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. And this contract has an estimated ceiling 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 repeat 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 IS 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 IS Engineers marks our third acquisition in 2023, which includes two acquisitions in critical infrastructure and one in federal solutions. In addition to bolstering our critical infrastructure portfolio through strategic acquisitions, we strengthened and reorganized this segment to better align with our customers, geographies, and end markets. and better position Parsons to capitalize on the unprecedented global infrastructure spent. 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 Corporate Equality Index for active support and inclusion of the LGBTQ plus 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 increases 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 in two high growth and complementary segments that continue to experience significant tailwinds. Starting with federal solutions, the proposed defense budget supports an $886 billion top-line budget, which is 3% higher overall than 2023. However, the Parson's 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 remains strong in all three geographies where Parsons operates, the United States, Canada, and the Middle East. We are leveraging our core competencies in engineering design, program management, and owner's representative to win and deliver on large, complex programs. As an industry leader in applying digital transformation to infrastructure, we look forward to continuing to transform this industry. Given our strong performance and our confidence in our current outlook, we are pleased to update the long-term guidance we provided at our investor day on March 15th, 2023. Matt will share more details, but in summary, we're raising our revenue growth targets, which is also off a total revenue base that is $1.2 billion higher than it was at the end of 2022. In addition, we expect average 20 to 30 basis points of margin expansion each year through 2025 and a free cash flow conversion rate of 100% or more of 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?

speaker
Dave

Thank you, Carrie. As Carrie 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 a rail and transit project, for which we realized a $38 million favorable impact to fourth quarter adjusted EBITDA. On the second program, within equity and earnings, we took a $58 million adjusted EBITDA charge. The impact was the result of supply chain challenges identified during the procurement of materials. Normalized margins excluding these 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. The 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 driven primarily by increased volume on new and existing contracts, accretive acquisitions, and continuing to closely manage costs. I'll turn now to our operating segments, starting first with federal solutions, where fourth quarter revenue increased by $280 million, or 50% from the fourth quarter of 2022. This increase was driven by organic growth of 47% and the contribution from our ceiling 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 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, or 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% and the inorganic revenue contribution from acquisitions. Organic growth was driven by higher volume on both Middle East and North America infrastructure programs. Critical infrastructure 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 profits from accretive organic growth on both new and existing contracts. For the full year, critical infrastructure's 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 infrastructure's adjusted EBITDA for the full year increased by $22 million, or 14% from 2022, and adjusted EBITDA margin decreased 50 basis points to 7.2%. The adjusted EBITDA increase was driven primarily by accretive organic growth and operating leverage. The lower margin was the result of fourth quarter $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 years, respectively. 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 in the prior year period. Our operating cash flow for the full year increased 72% to $408 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 leverage, strong free cash flow outlook, and balance sheet 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 a 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 IJA and global infrastructure investments will continue to drive demand and new business well into the future. Our recent contract awards and backlog 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 is closely aligned to the national defense strategy, low recompete risk, $8.6 billion of total backlog included fund backlog of $5 billion, and $14 billion of contracts won that are not yet reflected in backlog. For 2024, we expect revenue to be between $5.8 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 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 activity is expected to be between $350 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 Kerry mentioned, we're increasing the long-term targets we provided at our March 2023 Investor Day. At that time, we expected total revenue growth of 4% to 6%, and organic growth of 3 to 5 percent. 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 off 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 of 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 our organic growth with two to three accretive acquisitions per year to further drive shareholder value. In summary, we've reported exceptional results from the fourth quarter in a full year, and I'm confident in our ability to achieve results within our 2024 guidance ranges. We are operating in well-funded markets, have a great team that is executing at a high level, and I believe we are 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 Carrie.

speaker
Carrie 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 is 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 macro environment trends in two well-funded segments in six growing and enduring markets. With that, we will now open the line for questions.

Thank you. As a reminder, to ask a question, please press star 11 on your telephone and wait for your name to be announced. To withdraw your question, please press star 11 again. Please stand by while we compile the Q&A roster. The first question comes from Sheila Kayaglu with Jeffries. Your line is open.

speaker
Sheila Kayaglu

Good morning, everyone. Thank you so much. Happy Valentine's Day. I just want 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 is related to that. You know, you started off 23 years. guiding for organic growth up four. You closed up 23% and you accelerated into the year, which is kind of amazing. So I guess, what unlocked that? Can you talk about, was it hiring? Was it just award wins, new business? And how do you expect that to progress? Obviously, you've raised your long-term target.

speaker
Carrie Smith

Well, thank you, Shield, for the question. 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 this year at 66% with 93% of re-competes. We've secured all four of our major re-competes 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 deliver double-digit organic growth. So it's not one business unit driving persons. All four business units are delivering.

speaker
Sheila Kayaglu

Maybe if 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 implied for 2024? How do you see it? How much is locked in, whether it's in the backlog or the unbooked pipeline?

speaker
Carrie Smith

Yes, so we're really pleased with the Middle East growth being over 30% this year. We had some very strong wins in 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 with that said, the Middle East also, that growth is expected to peak somewhere between 2028 and 2030. So the nice thing is we've got strong tailwinds in both of our angiographies for the long foreseeable future. Great, thank you. Thanks, Sheila.

speaker

Please stand by for the next question. The next question comes from Toby Summer with Truist Securities. Your line is open.

speaker
spk11

Hey, good morning. This is Jasper Bibb on for Toby. I guess just following up on the negative 20 million adjustment in the CI segment, can you update us how much of that riskier 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?

speaker
Carrie 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 going to wrap up the first quarter of this year, which it did. That is going to send a $18 million tailwind for us as we enter this year because we had $18 million right 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's 90% done, and it 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 had been bid back in 2019 prior to COVID, so we got initial quotes at that time. We completed the design several years later, and we went back and we refreshed those quotes. We had less supplier availability, and those suppliers' prices have gone up. The good news is that this is kind of a one-off, I'm going to say, 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 look to 2024, we're going to be expanding our margins by 40 basis points.

speaker
Dave

Yeah, Jasper, I'd just add relative to critical infrastructure specifically, you know, the total year was about 7.2% within that business. We're expecting about 8.5% in 2024. Federal will still be in kind of the low nines, called 9.2%, and that's how we get to the 8.9% midpoint. Carrie and I have talked long term that by 2025, our goal is to have both segments operating over 9%. And a lot of the new work that we're bidding, as we've mentioned, is trending toward double digits. So really positive about the long-term projections for critical infrastructure.

speaker
spk09

Thanks.

speaker
spk11

And then the organic growth is obviously really impressive this quarter, but ran significantly ahead of your backlog growth in the book to bill. So just how should we think about the ability of the backlog, what you're seeing in the bid pipeline from the awards you won after the quarter to support further growth in 24 and 25?

speaker
Carrie Smith

Yes, 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. It's at $58 billion. Out of the $58 billion, we have 110 awards that are greater than $100 million. We also have a waiting 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 that have option years or unbooked ceiling. And we're confident on a good portion of that being able to convert over the next three years.

speaker
spk11

Got it. 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 and other expense in the guide.

speaker
spk13

So just any color on what that might be related to.

speaker
Dave

Yeah, I would say the overall pipeline for M&A remains strong. I think we're, you know, anything that's in the guide is related to prior transactions. So, as we mentioned, we closed the IS engineers deal in Q4. And so, again, the M&A pipeline is quite strong. We feel good about we closed three transactions in 2023. Our goal is two to three in 2024 as well.

speaker
Carrie 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 in the past. We generally look at companies that are between about $100 million and $500 million annual revenue. But as you noted, we did buy IS 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 you tend 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.

speaker
spk10

Thank you for taking the question.

speaker
Carrie Smith

Thanks, Jasper.

speaker
Operator

Please stand by for the next question. The next question comes from Bert Subin with Stiefel. Your line is now open.

speaker
Bert Subin

Hey, good morning.

speaker
Operator

I guess I'll echo everyone's thoughts.

speaker
Bert Subin

I mean, just amazing results.

speaker
spk24

Thank you, Bert.

speaker
Bert Subin

Thanks, Bert. So, Kerry, maybe just to follow up to an earlier question, you know, how do you think he keeps momentum going in federal solutions? I mean, he just grew essentially 4,000 basis points above the industry in the fourth quarter. And I'm just curious how much of that was driven by, you know, specific contracts, be it Bold Venture or additional work with the FAA. 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.

speaker
Carrie Smith

Yeah, so to take the second part first, our visibility is very good. The good news, too, we have very low repeat, 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 So the visibility and line of sight to that transitioning is good over the next three years. We anticipate roughly 50% of that to transition. How do we keep the momentum going is continue to keep a laser focus on our six core end markets. Those markets are all growing between 5% to 12% compound annual growth rate. Our goal has been to be differentiated, 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 in 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. If you look at critical infrastructure protection, the work that we've been doing with Department of State has been very good. Also one work in Indo-PACOM, expanding our footprint there with Kwajalein Housing. If you look over on the infrastructure side and transportation, we were awarded what at the time was our biggest design job since IPO with JFK Highways. We just surpassed that with the 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 the GIGA projects And the fact that we're not even going to see a peak there until later, you know, 2028 to 2030 timeframe, I think we've got a lot of momentum in the business.

speaker
Bert Subin

Maybe just as my follow-up, Carrie, you talked about the Middle East there. It's clearly been an engine for pretty significant growth. We saw it slow down on the growth basis, but 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 just from conflict in Red Sea? You know, in Israel, Hamas, or I guess as we think beyond that, you know, is there a geographic dispersion you expect? I mean, it sounds like Saudi's been really strong. Are you seeing strength in the UAE? Are you seeing a rebound in Qatar? Just curious how the Middle East is shaking out.

speaker
Carrie Smith

Yes, so from a risk perspective, the conflicts really don't pertain to the type of work we do because we're really doing infrastructure work. 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 all the people that live there because they'll have places to go for entertainment. Their education system is 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, intelligence type of work. We also do some RF emulator projects that we've seen deployed. Our geographic dispersion, we are the largest in Saudi Arabia, about 60%, 65% of our business is there. That's also been our fastest growing, followed by the UAE, which has 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 is 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 the traffic management system for that. We also did the Lausanne City Expo. 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.

speaker
Bert Subin

And, Carrie, I guess, Matt, just as sort of a last follow-up, on the cash side, you know, it sounds like Generation looks really good. And, you know, talking more like two to three deals a year versus maybe one to two. I guess in the meantime, how are you thinking about capital deployment? Are you just sort of willing to wait until you guys find the next deal?

speaker
Dave

Yeah, I think that's right, Bert. You know, obviously we have the share buyback program that's kind of nominal. We did about $11 million worth of share buyback in 2023, but definitely the focus is on M&A. And to your point, you know, the team has done an amazing job with the $100 million in op 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 the one to two deals to two to three is a mix of, you know, going from kind of a heavier federal to a mix of federal and CI, where the CI deals, as Kerry mentioned, are a little bit smaller. So we have capacity to kind of get to the two to three.

speaker
Carrie Smith

And that M&A really helps our momentum as well. You know, whether it's, if I look at the three recent deals, ceiling tech really expanded our presence in defensive cyber. We were strong in offensive. Now we can cover full-spectrum cyber operations. I talked about ISN 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 Keys is kind of nice at the intersection between federal and critical infrastructure, providing cyber compliance for energy and water companies. So all those acquisitions, as well as the ones that we've done in prior years, are helping momentum.

speaker
IP Keys

Great. Thank you so much, Matt and Kerry.

speaker
Operator

Thank you. Please stand by for the next question. The next question comes from Andrew Whitman with Bayard. Your line is open.

speaker
Andrew Whitman

Great. Good morning. Thanks for taking my question. I think I might just have one question today, and it's for Matt. as i look at the capital structure you've got this 400 million dollar convertible note out there it's uh fully hedged uh with the bond hedge uh that you've got uh on it and it looks like the the conditions uh to convert that to equity uh have been met with the trading performance of the stock here in the last several months so i guess my thought or my question is what are you going to do about this 400 million dollar face that's totally hedged out like I guess, is it fair to think of that as basically kind of gone or like not on the balance sheet because you've got the 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, if anything at all?

speaker
Dave

Yeah, I'd say, Andy, thanks for the question. I would say we obviously look at 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, you know, we continue to look at it. I would say that it remains on the balance sheet. It won't go current until August of this year. But we're continuing to look at options, you know, as we go forward. So no solid plan yet, but always looking at opportunities. Okay. Thank you.

speaker
Andy

Thanks, Andy. Thanks, Andy.

speaker
Operator

Please stand by for the next question. The next question comes from Alex Dwyer with KeyBank Capital Markets. Your line is open.

speaker
Alex Dwyer

Hi, team. Congrats on a great quarter.

speaker
spk24

Thank you, Alex. Thanks, Alex.

speaker
Alex Dwyer

So I wanted to ask about the organic revenue growth guide 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 of contracts. And if there's upside to this 7% revenue guide, where do you think we're most likely to see this upside come from?

speaker
Carrie 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 If you look at the 15 wins we've had in 2023, greater than 100, and the two that we just announced this year so far, it's across the board in all six of those end market areas. So it really affects all four of the business units.

speaker
Dave

Yeah, and I would say, you know, to kind of get to the high end, as Carrie mentioned, I think, in her script a little bit around, you know, labor markets. I think the U.S. budget, obviously, getting a deal done would be great. And so those are the things that we're looking through in terms of trying to get from the midpoint to the high end.

speaker
Alex Dwyer

Got it. Thanks. And then the critical infrastructure backlog continues to remain strong, but I wanted to ask about federal solutions with the 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 one times until the government gets a full budget?

speaker
Carrie Smith

So I would say fourth quarter is always late for federal government services. Third quarter is usually kind of a peak. But I would say the trailing 12 months is what we look at, which is very important, and that's been a 1.1. And so I think our federal business has been delivering quite fine. On the CR, no, I don't expect that to drive being below a 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 federal that we haven't 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.

speaker
Alex Dwyer

Thank you. Very helpful. Appreciate the thoughts.

speaker
Operator

Thanks, Alex. Thanks, Alex. As a reminder to ask a question, Please press star 11 on your telephone and wait for your name to be announced. One moment for our next question. The next question comes from Louie De Palma with William Blair. Your line is open.

speaker
Alex

Kari, Matt, and Dave, good morning and great fourth quarter. You're setting the bar very high. Thank you, Louie. Thanks, Louie. Are the Exitor ceiling tech and IP keys acquisitions performing significantly better than their revenue run rates prior to being acquired? And when Parsons integrates 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?

speaker
Carrie Smith

Yes, so I would say ExaTor has certainly been outperforming on a revenue front. Sealing Tech is really recent, but we do expect, you know, they're going to deliver a very strong performance. I'll talk about that in a minute. And IP Keys is on track with our expectations. We do get the value, as you're pointing out, Louis, 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 that. Great example would be IP Keys. They have a book of customers, hundreds of customers, in the utility and the water space. So in addition to selling those customers their capabilities, we can also sell the broader person's 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 Ceiling Tech and IP Keys and coming up with a new product line offering called Cyberscape, and we're going to be putting IP Keys capabilities on the fly awake at Ceiling Tech. So that's how quickly we do the integration and we drive synergies. But that's definitely a big factor helping our momentum.

speaker
Alex

Great. And another one, Parsons has been particularly strong with capturing customers classified cyber contracts over the past year. What is, in general, what is driving that strength? And are these cyber contracts or some of them affiliated with the geopolitical conflicts in Europe, the Middle East, and Asia? And in general, what is Parsons' presence with the Indo-PATCOM? Thanks.

speaker
Carrie Smith

Okay, so take the first one. What's driving the cyber? I would say, first, we're one of the leaders in offensive cyber, and that comprised about 75% of our business. 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 time of need, as you mentioned, such as the conflict affiliation. I can't comment too much more on that in depth just due to the classification nature. In the Indo-PACOM, we have several 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 for the Missile Defense Agency through our team's contracts. We're on Kwajalein Island. We built the Kwajalein Airfield. We're also just recently won the Kwajalein Housing, and we're looking for continued expansion there. Particularly, that budget got increased from $9.1 billion to 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 on cyber and intelligence type of work.

speaker
Alex

Great. And one for Matt, are your acquisitions, are they typically margin accretive and you just forecast that you would expect two to three acquisitions per year? And so in general, should these acquisitions be one of the drivers for your continued margin expansion that you've guided to as part of that 2025 outlook?

speaker
Dave

Yeah, absolutely, Louis. We target adjusted EBITDA of 10% or better, and so all these companies are performing well. I 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 expected to be accretive in a very short term and have strong cash flow as well.

speaker
Louie

Excellent. Thanks, everyone.

speaker
Operator

Thanks, Louis. Thanks, Louis. One moment for our next question. The next question comes from Mariana Perez-Mora with Bank of America. Your line is open.

speaker
Louie

Hi, this is Samantha Styro. I'm from Mariana. Hi, 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 kind of getting those certifications, are you seeing still a strong or like a long wait list there?

speaker
Carrie Smith

Yes, so overall in labor and hiring, 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 a percent 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 moved to DCSA back in 2019, and when it did, they were able to drop the backlog, and I want to 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 area is always going to be the most difficult, though, to hire, but we've seen some improvement in recent years.

speaker
Louie

Great. And then on these programs that you have the $14 billion of unbooked, would those require more hiring to keep up with? And are you kind of hiring ahead of that? Or do you have the people in place already?

speaker
Carrie Smith

Yes, so it's a mix. And I'll put them into two categories. When you look at it, about half that $14 billion of unbooked is option years. So those would be current programs that we're performing and we'll get follow-on options. In general, most of those would have the people performing the contract today. There might be some increased or surged scope as you go into the options, but generally those would be on board. The ones where we would get additional labor is the ones that are unbooked ceiling. So an example of that would be we won an air-based air defense program in Europe, and so that has just shy of a billion-dollar ceiling. So we book that as we get task orders, and those task orders represent all new work. So it's about 50-50. Got it. Thank you so much.

speaker
Matt

Thank you.

speaker
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.
