Well, thank you, Lynn, and thank you all for joining today's call to review our fourth quarter and full year 2025 results and discuss our business outlook for 2026. Let me also welcome Anne to her first earnings call as President of ICF International, Inc. And with that, let me start by saying that our fourth quarter results were firmly within our guidance ranges and capped a year in which ICF International, Inc. demonstrated notable resilience amid challenging conditions, our federal government business. In fact, delivered on what we said we would one year ago, and we are in to return to revenue growth in 2026 that at the midpoint represents an over 10% year-on-year swing. To summarize, 2025 revenues were firmly within our guidance framework, despite the direct and indirect impacts of the six-week government shutdown, we maintained our full year adjusted EBITDA margins at 2024 levels, despite the 7.3% dip in revenues. Revenues from non-federal clients increased 14% to account for 57% of full year revenues, led by 24% growth of revenues from commercial energy clients, of which 15% represented organic growth. And I'd say if any of year was a book-to-bill ratio of 1.19, a firm backlog of $3.4 billion, and a business development pipeline of $8.6 billion. All metrics that underpin our growth expectations for 2026. As I just highlighted, we saw robust demand for our services to commercial, state, and local, and international government clients throughout 2025, benefiting from the investments we have made over the last several years to build out key growth areas further diversify our business. In fact, we anticipate that this client set will achieve double-digit revenue growth again this year to account for more than 60% of our total revenues in 2026. The top performer in this grouping continued to be commercial energy, where client revenues reached just under $550 million and grew 23% in the fourth quarter and 24% in 2025. We are expecting another year of double-digit growth in this client category in 2026. The primary growth driver continues to be sustained strong demand from our utility clients for our market-leading energy efficiency, flexible load management, electrification, and grid optimization programs. Accounted for approximately 80% of our 2025 commercial energy revenues. These are critical areas for utility clients as they address the tremendous projected growth electricity demand, and the need for green resilience affordable energy. ICF International, Inc. is the market leader in developing and implementing residential energy efficiency, and new related programs for utilities with a 35% market share. We are continuing to gain market share the commercial and industrial energy efficiency space approaching a 20% share of this part of the market. Our market growth is a direct result of the strong performance of our programs, which consistently meet or exceed client objectives, as a consequence, we are winning a recantase benefiting from expanded scopes of work and taking away contracts from other providers. Additionally, revenues from our commercial energy advisory work picked up in the second half as the regulatory environment became clear to developers investors in the energy space. We saw higher demand for our grid engineering services, associated with accommodating data center loads as utilities expedite development of new substations. ICF International, Inc.'s energy keep engineering capabilities expanded considerably with our acquisition of CMY in 2023, but strengthened our offerings in grid modernization. And this is an area that we expect to build out further organically and potentially through tuck-in acquisitions. We're also seeing additional demand from small modular nuclear reactor developers seeking DOE funding market perspectives and regulatory support, along with demand for policy work, regarding SMRs from states and stakeholders. We also foresee work exploring the transmitted impacts of upgrading existing nuclear facilities. Our work on renewables is expected to continue to grow in 2026 led by solar and battery storage, a significant amount of renewable development has been safe harbor for investment tax credit purposes, creating sustained demand for our services for at least the next two to three years. Also, despite the reduced support from removals by the new administration, we see consistent private sector interest renewable and storage development on non-federal lands. This trend will continue through the advanced economics of these technologies and the need to meet the near-term demands of rapid load growth. And keep in mind that when we refer to our commercial energy revenues of $550 million this number does not include our energy-related work for federal, state and local, and international government clients, which amount to approximately $60 million in 2025. In fact, our commercial energy clients very much value ICF International, Inc.'s public sector work as it gives us a broader perspective on emerging technologies, as well as regulatory and policy issues. Moving ahead to our state of local government clients, our revenues increased 4.3% in the fourth quarter up 2.2% for the year. Our disaster recovery work accounted for approximately 45% of our 2025 state and local revenues and reflected our current support for over 80 active disaster recovery projects in 23 states and territories. ICF International, Inc. is recognized as a market leader in the development implementation of disaster recovery and mitigation programs just a few days ago announced that we were awarded a comprehensive management services contract by the state of Florida. This contract will enable us to compete for a wide variety of opportunities to help Florida improve, and accelerate statewide program delivery and strengthen long-term infrastructure resilience and we are very encouraged by this win. We continue to see HUD-funded procurement opportunities resulting from nearly $12 billion appropriation to enable long-term residential recovery, from disaster declarations in 2023 and 2024, and are actively positioning to compete for these procurements. As has been widely reported, the future rule of FEMA is under review. FEMA provides funding for the rebuilding of public infrastructure such as hospitals and schools following disasters and while this review has slowed the flow of funds, believe funding will ultimately flow to state and local governments. Lastly, our international government revenues increased 12.8% in the fourth quarter and 7.6% for the year, reflecting the ramp-up of contracts we won in late 2024 and early 2025 with the European Commission and the UK government. We expect to see greater growth in 2026 with a full ramp up of those contracts. Plus in January, we announced two significant new contracts to design and deliver large-scale communication campaigns across all 27 European Union member states. To sum up, we expect our revenues from non-federal clients to increase at a double-digit rate this year. Account for over 60% of our full year 2026 revenues. Let me now turn to the federal arena. As you know, 2025 was a challenging year. But we are looking ahead to a much improved 2026 for ICF International, Inc. Our revenues from federal government clients declined 25% year-on-year in 2025 as a result of contracts canceled between February and May, the slowdown in new procurements, and the direct and indirect impacts of the six-week government shutdown. In terms of where we stand today, our federal business is on much shorter footing than last year at this time. We were awarded approximately $1.1 billion in federal government contracts in 2025, representing about one half of our total contract wins for the year. About half of that amount represented new business including expanding the scope of current contracts, this is a good indication of ICF International, Inc.'s strong positioning in our federal markets. After last year's government shutdown ended, procurement activity picked up, and that momentum continued into 2026. Are seeing continued emphasis on efficiency, which we are well-positioned for, given that the vast majority of IT modernization work I think that's about one half of our federal government revenues, is outcome-based and done under fixed price and time and materials contracts. And we are starting to see a shift towards federal agencies outsourcing more work is creating additional opportunities for us. I know investors are concerned about the potential for GenTeC AI tools, such as Cloud Code and Gemini and Codex, eliminate the need for platform and service providers to play a central role in modernizing federal IT systems Ejecta coding tools can certainly speed up development they cannot replace the need for federal IT modernization. Here are three additional points to consider with respect to ICF International, Inc. First, as I just noted, 90% of our IT modernization work is outcome-based. Our civilian agency clients require a lot of support in this area. Thus, if we cannot complete certain projects in less time, at lower cost thanks to Adjenta AI, utilize available funding to move on to the next project. In other words, reducing costs increases the amount of backlog we can tackle for a client. Second, there is funding federal government budgets for IT modernization are robust. And recent reports indicate that a significant majority of federal IT systems still need modernization. And third, it is all about what you are doing and not doing in this arena. ICF International, Inc. does not maintain legacy systems. They do not manage project management offices. We do not run federal call centers. And we have exited others that we expect it to be commoditized due to AI. Rather, our work is in the higher end, higher margin areas like application development, cloud services, AI government governance, automation, data curation, and system post processing. In summary, AI is an accelerator and a net positive for ICF International, Inc., as we have already seen material improvement in our productivity, both in our client work and the internal management of our business. Looking across our technical development work more generally, we expect continued scrutiny around spending. But the market backdrop is much more stable than it was a year ago. And we see solid opportunities aligned with our core capabilities, particularly where agencies are modernizing systems improving efficiency, advancing mission-critical public health and or infrastructure priorities. In 2026, we expect revenues from federal clients to decline at a high single-digit rate. The 2026 will be a difficult comp as revenues in the 2025 included federal government work that was canceled between March and May. I'm sorry. February and May. On the plus side, we generally expect sequential improvement in federal revenues from the first quarter through the 2026 returning to year-on-year growth by the fourth quarter. To sum up our federal work, we have a firm backlog federal government contracts, a significant pipeline, and expect revenues from our IT modernization work increase this year. In 2025, we did navigate difficult business conditions to emerge as a stronger company in many ways. We are more diversified. We are more efficient. We are more agile. These advantages are positive catalysts for ICF International, Inc. in 2026 and beyond, demonstrated our confidence in ICF International, Inc.'s long-term outlook by repurchasing approximately 564,000 shares of our common stock last year of which about 220,000 were purchased in the fourth quarter. So with that, I will turn it over to our CFO, Barry Broadus, for his financial review. Barry? Thank you, John, and thank you, everyone, for joining today's call.
