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 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 and adjusted EBITDA for the 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 1.1x 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 re-compete. 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 life contaminated soil free 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 Treatability Lab in Syracuse, New York has been a leader in water treatment innovation for more than 30 years. The second multiple award contract that we won in the fourth quarter is a new five-year General Services Administration Public Building Services program. In this contract 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 re-compete 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, in 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 Parsons' core defense markets are growing at mid to high single digits. Given world-wide 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 owners 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 to 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?
