Thank you, Dave. Good morning. Welcome to Parsons' first quarter 2025 earnings call. We are pleased with our performance this quarter as we achieved record first quarter results for total revenue, net income, earnings per share, adjusted EBITDA and adjusted EBITDA margin. In addition, total backlog and funded backlog are at all-time highs. We also delivered a $52 million year-over-year improvement in our operating cash flow, achieved our best employee retention since 2020, and we reported a 1.1 times book-to-bill ratio, which was supported by a 1.4 times ratio in our Critical Infrastructure segment. We achieved these results despite our confidential federal contract operating at a reduced volume compared to 2024. As we reported last quarter, our contract has continued. However, a related contract was paused due to a presidential executive order, which has caused lower volume on our work. On today's call, we continue to provide transparency and to illustrate the strength of our entire portfolio and the growth we're experiencing in the rest of our business, we will discuss revenue results both with and without this confidential contract. Additionally, we are reiterating all 2025 guidance metrics. As stated last quarter, the guidance midpoint is aligned to the negotiated value of option year two of the confidential contract. As we wait for the decision on this important mission to proceed, I commit to investors that we will continue to deliver best-in-class execution across the entire portfolio. In the Critical Infrastructure segment, we are capitalizing on unprecedented spending in both North America and Middle East infrastructure markets. In the United States, this is particularly exciting, given the current infrastructure spend is not expected to peak until 2028, and we'll have a six to eight year tail after that. In addition, discussions on the next surface transportation bill are already underway. Our focus on hard infrastructure such as roads and highways, bridges, airports, rail and transit has bipartisan support and is a priority for the new administration. In the U.S., we continue to win some of the largest and highest priority projects in our company's history, recognized by engineering news record in the top three companies in three categories we are punching well above our weight class. Our Middle East infrastructure business also continues to excel. Where we're the number one program manager throughout the region. In Saudi Arabia, we're involved in nearly every major project throughout the Kingdom as we help them achieve Saudi Vision 2030 and prepare for the upcoming world events, including the Asian Games, the World Cup and the Expo. The expected public investment fund giga project spend for infrastructure is $1.3 trillion by 2030. In the UAE, we're experiencing significant growth as Abu Dhabi implements their urban evolution program and Dubai to place their 2040 master plan. Also, Qatar has a National Vision 2030 objective, which is driving our expansion in that country. The focus of the Gulf Cooperation Council countries on trade and tourism, diversification and a booming real estate market is accelerating infrastructure demand. Given our six decade history in the region and proven performance on delivering new complex projects, we are well positioned to continue to capitalize on these long-term tailwinds. Representing 46% of Parsons Q1 revenue, we expect our global infrastructure portfolio to continue to thrive, not just this year, but well into the next decade. In our Federal Solutions segment, we're excited about the upward momentum in the defense budget with the congressional Republicans releasing a budget reconciliation bill that would increase defense spending in the coming years by $150 billion. Our portfolio aligns with major budget reconciliation areas, including missile defense, munitions, Pacific and nuclear deterrence, border security and more. In addition, plans were unveiled for the first potential $1 trillion defense budget in fiscal year 2026. Parsons portfolio alignment to 10 of the 17 priority areas outlined in the February 2025 Department of Defense memo is encouraging. Since we anticipate 8% of the budget to be realigned to these focus areas for each year across the future year's defense program. Parsons strong position and differentiated capabilities in integrated air and missile defense, aviation modernization, space superiority, counter unmanned air systems, cyber operations, electronic warfare, munitions and border security as well as our geographic presence in the Indo-Pacific region will enable us to capitalize on this increased spending. We are a non-traditional company that was purpose built to be agile and innovative, and we're, therefore, pleased to see the administration's focus on software acquisition pathways, commercial solutions opening and other transaction agreements to enable us to rapidly deploy solutions that are operationally relevant. This approach aligns very well with our strategy that's been in place since the day that I became the CEO of Parsons to be an advanced solutions integrator that differentiates with software. Parsons organic investments and strategic acquisitions have positioned us as a technology leader in important emerging national security markets including artificial intelligence, assured position, navigation and timing, cyber, signals intelligence and biometrics. And finally, our synergistic national security and infrastructure portfolio uniquely positions us to help solve some of the world's most difficult challenges. These include critical infrastructure protection of our utilities, water, facilities, transportation and health care systems. PFOS, PFAS, emerging contaminant elimination. Aviation modernization for both the Federal Aviation Administration and Global Airports. Events Management, such as the upcoming Olympics, World Cup and Expo. Rebuilding of cities, towns and countries throughout the world and energy resilience. We are excited about the unique growth aspects at the intersection of critical infrastructure and Federal Solutions and how we've been able to leverage our differentiated portfolio. Moving to our first quarter results. Record total revenue for the first quarter was $1.6 billion, a 1% increase over the prior year period and a 2% decline on an organic basis. If you exclude the revenue impact from our confidential contract, our total and organic revenue growth rates would have been 11% and 7%, respectively. These results are in line with the mid-single digit or better organic revenue growth target we provided on our fourth quarter 2024 earnings call. This growth validates the strength of our portfolio and our alignment to national security and infrastructure priority spending areas. Margins were exceptionally strong in the first quarter as we achieved record first quarter adjusted EBITDA margins of 9.6% at the enterprise level and 10.3% within our Critical Infrastructure segment. Our margin expansion is driven by our emphasis on our infrastructure core competencies, including program management, owners engineer and design engineering. This deliberate focus and performance execution drove 40 basis points of margin expansion in the first quarter of 2025. For the total year, margins are projected to expand 30 basis points after expanding 50 basis points in 2024. We also delivered record first quarter net income and earnings per share. Additionally, cash flow results were favorable as a result of strong collections in both segments. During the first quarter, we achieved a book-to-bill ratio of 1.1 times on an enterprise basis, driven by strong win rates of 68% and large contract wins. For the first time since our IPO, we exceeded $1 billion in quarterly contract awards in our Critical Infrastructure segment and achieved our 18th consecutive quarter with a book-to-bill ratio of 1.0 or greater. In our Federal Solutions segment, award activity met our expectations with a book-to-bill ratio of 0.9 times. In addition, this is the seventh consecutive quarter where our pipeline has exceeded $50 billion, illustrating the demand for our solutions and only the second quarter in the history of our company with a backlog of more than $9 billion. We continue to win large strategic contracts across both segments and all six end markets. In this quarter, we were awarded four contracts that each exceeded $100 million, demonstrating the demand for our Federal Solutions and the national security alignment of our portfolio, three of the four wins greater than $100 million in the first quarter were in our Federal segment, and we won an additional $95 million federal contract during the quarter. And just after the quarter ended, we were awarded another new federal contract valued at greater than $100 million. With that background, let me discuss our first significant first quarter wins. We were awarded an option year totaling $243 million on our general services administration contract. This for both new and continuing defense work, delivering global quick reaction capabilities to leverage advanced technology solutions across the old domain battle space. This award is part of our cyber and intelligence end market, which continues to achieve double-digit revenue growth after two years with growth of more than 20%. We received $232 million in option year funding from a confidential customer in our critical infrastructure protection market. We were awarded a follow-on program and construction management contract in Dubai valued at over $200 million. In the UAE, we're seeing continued growth in both our transportation and urban development markets. An additional $125 million ceiling value modification was added to Parsons cyber threat hunt forward program. In Space and Missile Defense, we received a new $95 million contract for operational fielding and sustainment of the United States Air Force Europe, Air Defense early warning capability to U.S. and NATO partners across the European Command area of operations. And after the first quarter ended, we were awarded a new five year task order for cyber assessment work, supporting the Defense Threat Reduction Agency. This single award contract has a ceiling value of $138 million. During the first quarter, we acquired TRS Group, an industry leader in PFAS, thermal and holistic environmental remediation, having cleaned hazardous and toxic substances from soil, ground water and fire suppression systems for global clients. This $37 million acquisition enhances Parsons environmental remediation capabilities in both operating segments and serves as a force multiplier for our industry leading PFAS remediation solutions. As a testament to the importance of ethics and integrity in our company, we are proud to be named one of the world's most ethical companies by Ethisphere for the 16th consecutive year. In summary, I am pleased with our first quarter results as we achieved records across the financial metrics. In addition, we leveraged our balance sheet and closed an accretive acquisition and opportunistically executed on our share repurchase program. Our balanced portfolio and 6 growing and profitable end markets are enabling us to achieve mid to high-single digit organic growth across the company, excluding the confidential contract. Simultaneously, our adjusted EBITDA continues to expand faster than our top line, resulting in margin expansion. In Critical Infrastructure, we're capitalizing on unprecedented global infrastructure spending and leveraging our strong position and reputation in the North America and Middle East markets. In Federal Solutions, our portfolio is aligned with the new administration's national security priorities as well as their desire to deliver fast, innovative and operationally relevant solutions that outpace near peer threats. As we look to the future, we have long-term tailwinds in both segments. In addition, we have record total backlog of $9.1 billion, of which 69% is funded. Approximately $12 billion of contract wins that we have not yet booked. A $55 billion pipeline that includes over 100 opportunities that are worth more than $100 million each and 19 opportunities worth more than $500 million each and we have only 2% of our revenue up for recompete in 2025. As a result of these tailwinds and the proven confidence I have in our team's ability to deliver strong financial results, I'm extremely excited about our bright future and our ability to continue to drive long term shareholder value. With that, I'll turn the call over to Matt to provide more details on our first quarter financial results. Matt?
