Good morning. Thank you for participating in the Parsons Corporation Annual Meeting of Stockholders. I'm Carey Smith, CEO and President of Parsons Corporation. Please join me in welcoming key participants who are attending this meeting, including our Board of Directors, company executives, ESOP Trustee, Ascensus, and audit firm, PwC. From our Board, I'd like to welcome George Ball, Mark Goldthorpe, Steve n Leer, Letitia Long, Ellen Lord, Sarah Macdu, Harry T. McMahon, M. Christian Mitchell, Robert H. Smith, Suzanne Vautrinot, and David C. Wajsgras. Also joining the meeting today are company executives, Matt Ofilos, Chief Financial Officer, John Martinez, Chief Legal Officer and Corporate Secretary, and Dave Spille, Senior Vice President, Investor Relations.
Members of the ESOP Policy and Advisory Committee are in attendance, as are Will Glasgow and Bill Ryan, representatives from Ascensus, the ESOP Trustee. Joining us from PricewaterhouseCoopers, the corporation's independent registered public accounting firm, is Kathleen Hopley and Austin Ureel. Most importantly, I want to welcome our stockholders that are participating in today's meeting. Thank you for your support of Parsons. The meeting will come to order. I will preside over the meeting. Parsons' Chief Legal Officer, John Martinez, will act as Secretary of the meeting. Joining us from American Election Services, the Inspector of Elections for the annual meeting is John Mumber.
As described in your proxy statement, at today's meeting, we will address the following matters, election of directors, the approval of the ratification of the appointment of PricewaterhouseCoopers as Parsons' independent auditors for fiscal year 2026, and an advisory vote to approve executive compensation. Before starting the formal business of the meeting, I would like to reiterate some of the key points I shared in my letter to our stockholders in our annual report.
I will refer to certain non-GAAP financial measures, which, as a reminder, are not a substitute for their comparable GAAP measures. A reconciliation of GAAP to non-GAAP measures can be found in our annual report on Form 10-K for the year ended 31 December 2025, which is available on our website. 2025 was a dynamic year that reinforced the strength of our diverse and resilient portfolio despite headwinds such as the longest government shutdown in history, regulatory shifts, and government reprioritization. Thanks to the more than 21,000 dedicated, focused, mission-driven members of our Parsons team, both of our segments achieved significant gains, posting strong total revenue and adjusted EBITDA results. Our trailing 12-month book-to-bill ratio was greater than 1.0, which has been maintained since our IPO in 2019. Adjusted EBITDA margins expanded 60 basis points to 9.6%, a company record.
Additionally, we delivered free cash flow conversion of 100% and exceeded the high end of our fiscal year 2025 cash flow guidance range. We also completed three accretive and strategic acquisitions in 2025 and a fourth in January of 2026, welcoming the teams and capabilities of TRS, Chesapeake Technology International, Corp. Applied Sciences, and Altamira to our Parsons family. From 2023-2025, we drove long-term stockholder value by exceeding the high end of all our Investor Day targets, total revenue, adjusted EBITDA, and operating cash flow. These results demonstrate that our growth strategy is working. As stockholders, you know that our focus is always on the future, anticipating and delivering on our global customers' most urgent needs.
I remain confident in our momentum, thanks to our strong alignment to global priorities and long-term tailwinds, including continued infrastructure investment across our geographic markets and our Critical Infrastructure segment in an exquisite, operationally relevant portfolio of capabilities in our Federal Solutions segment. As I shared in my letter, we can also uniquely use our synergistic portfolio to expand our offerings in cyber, critical infrastructure protection, per- and polyfluoroalkyl substances or PFAS, decontamination and community rebuild, emergency management, energy resiliency, and aviation modernization by bringing expertise and solutions from across our global capabilities to deliver the next-generation integrated solutions our customers need and our world demands. Going forward, we plan to continue our strategy as an advanced solutions integrator that designs, builds, and integrates complex end-to-end systems to drive clear mission and business outcomes.
Customers choose us as their single accountable partner for measurable improvements in cost, speed, and performance. By exploiting digital technology, including artificial intelligence, we believe we will further accelerate growth, create transformative solutions, and enhance efficiency. Foundational to our success is our strong, stable, and funded backlog and $11 billion of single-award contract wins that I've previously noted we have not yet booked, complemented by our leading positions in six growing, enduring, and profitable end markets. Our growth trajectory, underpinned by our tailwinds, backlogs, and our truly dedicated global workforce and culture, are why we believe our strategy will continue to work and how we will continue to deliver long-term stockholder value. Thank you for being a stockholder and for your support to our company. Now, let us proceed to the business agenda.
We will entertain relevant questions from stockholders once we have concluded the formal business set forth in the agenda. Please refer to our rules of conduct posted on the meeting website. Will the Secretary of the Meeting report on the quorum?
The corporation's proxy statement was sent by Broadridge Financial Services to all of the corporation's stockholders of record as of February 13, 2026. The ESOP trustee is the corporation's largest stockholder. The trustee has the right to vote all of the corporation's shares, which are held in the ESOP trust. Each ESOP participant has the right to advise the trustee on how their interest in the trust should be voted. I possess a certified true and complete copy of all of the stockholders of the company at the close of business on February 13, 2026, the record date. The number of shares of common stock outstanding at the record date and entitled to vote was 107,011,496. Each share of Class A common stock is entitled to one vote.
I confirm that a sufficient number of shares of the corporation's common stock are present for the meeting, either through attendance or by proxy, representing a quorum for the meeting. The meeting is therefore legally constituted.
On the basis of the report of the Secretary, I declare that a quorum is in attendance. Before we begin with the formal business of the meeting, would the Secretary please take a moment to review the procedures that will be followed during today's meeting?
As Ms. Smith mentioned, there are three matters for consideration at this Annual Meeting of Stockholders. One, the election of four Class 1 Director nominees to the Board of Directors of the Parsons Corporation. Two, the approval of the ratification of the corporation's independent registered public accounting firm for fiscal year 2026. Three, a non-binding advisory vote on the compensation for the corporation's Named Executive Officers as disclosed in the Compensation Discussion and Analysis section, or CD&A of the proxy statement. After the presentation of all the agenda items, the polls will be closed. First matter to be voted upon is the election of four Class 1 Director nominees to serve from the time of election and qualification until the 2029 Annual Meeting of Stockholders. The nominees for election to the Board of Directors are Carey Smith, Letitia Long, Harry T. McMahon, and Robert H. Smith.
The second matter to be voted upon is the ratification of the appointment of PricewaterhouseCoopers as the independent registered public accounting firm for the Parsons Corporation for the fiscal year 2026. The third matter to be voted upon is the advisory vote of the corporation's stockholders for approval of the compensation of the corporation's named executive officers, as disclosed in the Compensation Discussion and Analysis section of the proxy statement.
We will now proceed to the voting on the agenda items, as well as the question and comment period relating to the agenda items. I want to emphasize that if you have previously voted by proxy and do not wish to change your vote, you do not need to vote again on the virtual meeting website. Voting on the website revokes your prior proxy. If any stockholder has not already voted or wants to change his or her vote, please do so prior to the closing of the polls. I declare the polls open. Does any stockholder have a question or comment relating to any of the agenda items?
We have a stockholder question related to the agenda. The stockholder is requesting where they can find the Compensation Discussion and Analysis as it relates to the company performance, which will inform voting on Question one, which relates to the election of four director nominees named in the proxy.
Thank you for your question. The Compensation Discussion and Analysis is set forth beginning on page 29 of the proxy statement, which discusses company performance in 2025, among other things, and Director Compensation discussion begins on page 70 of the proxy statement.
There are no further stockholder questions that relate to the agenda.
I will be closing the polls momentarily. If any stockholder has not already voted or wants to change his or her vote, please do so at this time. I will pause for a brief moment to allow any last votes to be submitted. I now declare the polls closed. Would the Secretary please provide the preliminary voting results on the proposals?
Based on the preliminary count of the Inspector of Election, stockholders have elected each of the four Class 1 director nominees. Stockholders have ratified the appointment of PricewaterhouseCoopers as the independent registered public accounting firm for Parsons Corporation for the fiscal year 2026. Stockholders have ratified the advisory vote on the compensation of the corporation's named executive officers. The final vote results will be disclosed in a Form 8-K filed with the Securities and Exchange Commission. This concludes the formal business of the Parsons Corporation annual meeting of stockholders.
Thank you, Mr. Martinez. Do we have any questions submitted by stockholders?
We have a question submitted by a stockholder as follows. With the recent stock price depression, what is the company's approach to address it?
Thank you very much for your question. Recently, there have been dynamics at play that have impacted our stock price, including but not limited to DOD, the longest government shutdown in history, a contract cancellation by the administration, and the Middle East conflict with Iran. As a company, we are focused on what we can control and having alternatives for what we can't control. Despite the challenges we faced in 2025, we delivered very strong cash flow, margin expansion, and strong revenue growth, excluding the contract that was canceled by the administration. When assessing a company's performance, it's important to examine the creation of long-term shareholder value. From December 31st, 2021, through December 31st, 2025, Parsons stock improved 83.7%, nearly doubling the S&P 500 growth of 43.6%.
I am confident that by persisting with our growth strategy, we believe we will drive long-term stockholder value as we did in 2022, 2023, and 2024, each of which had stock price returns of more than 35%.
Finally, for answers to any questions pertaining to the employee stock ownership plan, I refer ESOP participants to the ESOP administrator, USI. They can also be reached at 855-539-8695 between 7:00 A.M. and 7:00 P.M. Central Time, or via online inquiry at retirementFocus, all one word, .com. If the stockholders have questions, they may contact Mr. Dave Spille, Parsons Senior Vice President for Investor Relations.
That concludes the 2026 Annual Meeting of Stockholders of Parsons Corporation. The meeting is now adjourned. Thank you for attending and for your continued interest in Parsons Corporation.
The conference has now concluded. Thank you for attending today's presentation. You may now disconnect.
