Thank you, Adrienne, and welcome to everyone joining us today. I will start with an update on our record 2025 results, provide 2026 guidance, and speak generally about the earnings presentation shared on our website. Allan will then provide the financial highlights, and following our prepared remarks, we will host the question-and-answer session. Before we get into the numbers, I want to acknowledge the extraordinary work of our approximately 3,500 colleagues around the world. 2025 was a record year across every key dimension: revenue, EBITDA, and cash flow. The reason we win quarter after quarter and year after year isn't luck or timing. It's because we bring science, field expertise, and urgency to the problems our clients need solved right now. Our results continue to demonstrate that environmental stewardship, human development, and shareholder value creation are not intention. At Montrose, we are for planet and for progress. As we have noted each quarter, our business is best assessed on an annual basis as demand for environmental science-based solutions does not follow consistent quarterly patterns. We manage our operations on an annual basis, and we recommend you similarly view our performance that way. With that context, I'm extremely pleased to report that 2025 was the strongest year in Montrose's history. We delivered full year revenue of $830.5 million and consolidated adjusted EBITDA of $116.2 million, both record highs and both well above the initial guidance we provided at the start of 2025. Let me put that record performance in context. Revenue grew 19.3% versus 2024, driven by organic growth of 12.7%, which meaningfully exceeded our long-term organic growth target of 7% to 9%. All 3 segments delivered solid organic revenue growth, thriving despite the ongoing regulatory uncertainty from the U.S. federal government. Consolidated adjusted EBITDA grew 21.3% year-over-year, and our consolidated adjusted EBITDA margin expanded for the third consecutive year, reaching 14% in 2025, representing 180 basis points of improvement since 2022. And importantly, we did not just grow the top and bottom line. We delivered record cash flow and exceeded every major strategic objective we set for ourselves in 2025, which Allan will expand upon in his remarks. Montrose has now delivered approximately 20% revenue CAGR from 2020 through 2025, outpacing the Russell 2000 constituent average, driven by roughly 13% average annual organic growth and resilient demand tailwinds across our diversified end markets. I am very proud of this team for delivering these exceptional results while maintaining their focus on our mission and on our clients. I also want to take a moment to address something directly because we continue to hear questions about it from investors. There is a persistent narrative in the market that U.S. regulatory volatility and uncertainty creates meaningful headwinds for Montrose. Let me be direct. The macro and regulatory backdrop for environmental services and solutions remains as constructive as we have seen, and the performance we delivered in 2025 is the clearest possible evidence of that. In 2025, approximately 90% of our clients operated in a diverse subset of private sector industries, including energy, utilities, transportation, industrial manufacturing, chemicals, and technology. Our work creates more efficient operations, reduces their environmental impact, and derisks their growth. We achieved this by delivering environmental consulting, measurement, and treatment through a unified service model. The real economy still needs a reliable environmental partner, and this demand doesn't stop for a new headline cycle. As industrial activity picks up in our key markets in the U.S., Australia, and Canada, we are seeing increased demand from the mining industry, pharmaceutical companies, particularly the GLP-1 manufacturers, the semiconductor industry, and technology companies building data centers. The air monitoring or water treatment needs for our clients in these sectors has picked up materially and were not part of our outlook 18 months ago. We expect these dynamics to support strong organic growth well into the foreseeable future. Despite the strong demand tailwinds across the majority of our business, 2 regulatory dynamics, in particular, have garnered a fair amount of recent attention. On methane, the market perception is that recent EPA framework changes, such as the Endangerment Finding repeal, threaten our business. The reality is there is no material impact on our services expected in the near term. Even though the essence of U.S. EPA changes haven't altered the regulations underpinning our work, more importantly, our methane services work is concentrated with large operators in states with independent stringent regulations, including states like Colorado, Texas, California, and Pennsylvania, states that have implemented their own monitoring frameworks and continue to set expectations that require credible monitoring and abatement. Meanwhile, the EU methane regulation extends the market for emissions monitoring, reporting, verification, and abatement to exporters, including U.S. LNG and oil producers. Because Montrose invested early in advanced monitoring and verification-ready technologies, our energy clients can achieve better, faster, and more cost-effective outcomes. With global deadlines phasing through 2030, demand is now more predictable. And on PFAS, while the market remains focused on headlines, PFAS is already a high-margin growth driver across our segments. U.S. EPA and White House actions continue to elevate PFAS as a priority. In Q2 2025, the U.S. EPA provided clarity on national PFAS standards, which expanded our pipeline. Ongoing state actions around maximum contaminant levels, AFFF remediation, and industrial discharge standards are also driving long-term demand for our services. States and utilities are tightening expectations around landfill leachate, for example. And as a result, pretreatment and full-scale opportunities increased for Montrose in 2025, and we expect elevated accretive organic growth in water treatment through 2026 and beyond. We are seeing similar demand increases in our Australian market. On broader regulatory uncertainty, again, our track record speaks for itself. We have delivered consistent organic growth across multiple administrations and regulatory cycles. This is not a coincidence. It is a function of our business model. Our business is predominantly private sector, with U.S. federal government exposure of less than 3% of revenue. The private sector clients that represent 90% of our work are not waiting on Washington. They have their own environmental obligations, their own sustainability commitments, and their own operational needs that drive sustained, predictable demand for our services. It is important to note that our addressable market for water treatment extends well beyond PFAS itself. Our water treatment total addressable market exceeds $250 billion. Ours is a water technology business, not just a PFAS business. Our IP and process expertise are solving challenges across contaminants and industries, from pharma and semiconductors to waste and industrial clients. PFAS is a tailwind, but the larger story is scalable, trusted water technology solutions. The short answer for Montrose is this: macro and regulatory drivers are tailwinds that endure. The backdrop is familiar, economic volatility, policy fluctuations, and evolving regulatory frameworks drive complexity that creates demand for the various services where we choose to compete and where we have built capability. Our private sector clients tell us 3 things consistently: their long-term outlook has not changed, domestic industrial activity is a net positive, and they remain committed to state regulations and international rules because compliance is a license to grow. With more than 6,000 clients, we've seen very few material changes to operating policies. That durability underpins our confidence. We expect to publish a study with the Financial Times around Q2 2026 that demonstrates how the private sector is responding to U.S. environmental policy volatility. By and large, the data shows that the private sector, Montrose's clients, are staying the course and that steadiness is manifesting in our numbers. These dynamics are a meaningful part of our confidence as we launch our 2026 guidance. Transitioning first to our priorities for 2026. Our strategic focus is clear and consistent with what you have heard from us. Let me take this in 3 pieces. First, organic revenue growth and margin expansion. Our go-to-market strategy, anchored by cross-selling our unique portfolio of services to private sector clients, coupled with regulatory and policy tailwinds across our key markets, and broad increases in industrial activity, continues to demonstrate the resilience and compounding power of our integrated platform. We have exited 2025 with strong momentum in all 3 segments, and we see broad-based demand across the private sector clients in 2026. As one data point, the percent of revenue from cross-selling increased from 53% to 62%. Our growth is not dependent on acquiring any more customers, but rather on deepening the relationship with our existing customers. Second, strong cash flow generation. We have consistently prioritized working capital discipline and operational efficiency. The 93% operating cash conversion we delivered in 2025 was extraordinary. While we do not expect to sustain that exact level, we remain confident in achieving 60% operating cash conversion in 2026, which exceeds our long-term 50%-plus operating cash flow to consolidated adjusted EBITDA target. Free cash flow is also expected to remain robust in 2026, providing the foundation for our capital allocation strategy. Third, strategic capital allocation. Now that we have completed the balance sheet simplification we committed to in 2025, we have expanded flexibility to deploy capital in ways that enhance the shareholder value, including through organic investments, M&A, and share repurchases. I will come back to each of these in a moment. Turning to our 2026 outlook. We are introducing guidance of $840 million to $900 million in revenue and $125 million to $130 million in consolidated adjusted EBITDA. At the midpoint, that represents approximately 10% EBITDA growth compared to 2025. This guidance does not assume any acquisition impact. We are targeting approximately 15% consolidated adjusted EBITDA margins in 2026, reflecting the operating leverage inherent in our model, ongoing efficiency gains, and the benefit of our higher-margin service mix. This is an important signpost for us and one I want to clearly anchor on for the investment community. Organic revenue growth of 7% to 9% remains our long-term expectation. And for 2026, we expect to be at the high end of that range. Revenue in the second half of 2026 is expected to be higher than the first half, with the second half contributing approximately 60% of full year consolidated adjusted EBITDA given the timing of current projects. Our 2026 environmental emergency response revenue assumption is in the range of $50 million to $70 million, consistent with our long-term framework. As always, our formal guidance assumes no impact from future acquisitions. I also want to highlight a milestone that is easy to overlook, but tells a powerful story about the compounding cash generation power of this business. Between 2025 and 2026, we expect to generate approximately $180 million in cumulative operating cash flow. We achieved record operating cash flow of $107 million in 2025 alone, a 93% conversion rate. We expect sustained strong conversion in 2026, supported by ongoing margin expansion and working capital discipline. This trajectory positions Montrose to continue enhancing cash flow and driving shareholder value. Before I hand the call over to Allan, I want to reaffirm the framework that underpins our capital allocation philosophy and our ability to create long-term shareholder value. On organic investments, we will continue allocating 1% to 2% of revenue annually to high-return investments in proprietary technology, software development, patents, R&D, and growth capital expenditures. These are the innovations that expand our applications and strengthen our competitive position over time. And they are a large part of why our organic growth has averaged 13% for the past 5 years. On balance sheet strength, our strong liquidity provides flexibility for strategic initiatives while we maintain a disciplined and balanced approach. On share repurchases, I am pleased to announce that we are in a strong position to begin returning capital directly to shareholders through our existing $40 million share repurchase authorization. Considering the ongoing disconnect between the company's strong financial and operating performance, our near- and long-term optimistic outlook, and our current public stock valuation, the program reflects our confidence in Montrose's business trajectory. The confidence we have in our performance, our 2026 outlook, and the macro tailwinds supporting this business makes this the right moment to begin this program in a systematic and ongoing way. On acquisitions, having delivered on every objective we set when we announced the acquisition pause in late 2024, including full balance sheet simplification, record cash flow and continued margin expansion, we are now in a strong position to return to accretive acquisitions in 2026. Acquisitions remain a key part of our long-term strategy, our growth algorithm, and our investment thesis, and our pipeline today is as robust as we've seen in recent years. As we have said before, we will remain prudent on leverage. We remain focused on highly strategic, accretive tuck-ins that enhance cross-selling opportunities, expand market presence, and optimize our service mix for continued margin enhancement. In summary, 2025 was a record year for Montrose in every meaningful sense. We delivered record revenue, record EBITDA, record cash flow, and record margins. We exceeded every key strategic objective we set for ourselves. We enter 2026 with a simplified balance sheet, strong liquidity position, and clear strategic momentum. Demand remains very strong in all of our key markets, the United States, Australia, and Canada. I am extremely proud of the Montrose team and everything they have accomplished, and I remain deeply optimistic about what lies ahead. Thank you for your continued interest in Montrose. And with that, I will hand it over to Allan.
