Thank you, Adrianne, and good afternoon, everyone. Thank you for joining us. Before we begin, I'd like to thank our Onterris employees around the world. Their dedication, technical excellence and commitment to our clients are central to what we do, and I want to thank them for all that they do. Their commitment to our clients and to one another is why we continue to succeed. This afternoon, I'll share how we're thinking about second quarter results, discuss our updated 2026 outlook and summarize priorities we are focusing on to strengthen Onterris and enhance value creation for all stakeholders. As we have noted each quarter, our business is best assessed on an annual basis. Demand for environmental science-based solutions can be variable in any given quarter, particularly when environmental emergency response activity is significantly above or below historical levels. On an annual basis, the underlying demand profile and long-term trajectory of the business is very consistent. This is why we manage our operations on an annual basis, and we recommend you similarly view our performance. Second quarter revenue was $186.7 million, below our expectations, primarily due to historically low environmental emergency response and related recovery services. Consolidated adjusted EBITDA was $31.9 million or 17.1% of revenue. Although revenue was lower, EBITDA margins increased from 16.9% in the prior year quarter, reflecting successful ongoing cost optimization. I would also like to remind our audience that the second quarter of 2025 included approximately $53.6 million of revenue associated with the single environmental emergency response event and the recovery work that followed. While second quarter revenue declined without that single event, second quarter 2026 revenue grew. Based on our first half performance and current visibility, we are updating our full year revenue guidance range to $740 million to $790 million. This revised range reflects 3 drivers at the midpoint. First, approximately $45 million lower pass-through revenue; second, approximately $40 million lower emergency response revenue; and third, approximately $20 million of other revenue impacts and examples of other revenue impacts include temporary regulatory waivers, some of which were recently issued for federal and state air permitting rules that remain promulgated. We are also updating our full year EBITDA guidance range to $117 million to $120 million, a change of $9 million at the midpoint. The encouraging news is despite a more significant drop in revenue, the impact on EBITDA is limited and our margins are higher. Every outcome within this updated EBITDA guidance range would represent a new record for Onterris. That's not just a financial milestone. It is evidence that the business continues to become more profitable even in a year when revenue expectations have moved lower. EBITDA margins at the midpoint of the updated guidance have increased to 15.5%, representing approximately 150 basis points of expansion compared to last year and 50 basis points of margin expansion compared to our original 2026 guidance. Successful ongoing cost optimization offsets a meaningful portion of the earnings impact from the lower revenue outlook. It is also important to note that despite a lower revenue outlook, our full year operating cash flow expectations are largely unchanged from the beginning of the year due to the strong underlying performance of our core business. We continue to expect strong operating cash flow equal to approximately 60% of full year EBITDA, including $70 million to $80 million in the second half of 2026. We also expect year-end leverage of approximately 2.5x, which is flat year-on-year despite $30 million of share repurchases, an additional $16 million in payments for bonuses earned in 2025 and $11 million in contingent acquisition-related payments in the first half of this year. Taken together -- our revised expectations reflect underlying growth in the core business, improved profitability and strong cash generation power of the business. Our expectations are grounded in our relatively predictable testing business and known Consulting and Treatment projects. To be clear, this shift in 2026 outlook does not diminish the importance of environmental emergency response to Onterris. Response remains an important capability for our clients and attractive business for us and important for cross-selling. It is often the beginning of long-term client relationships that extend well beyond the initial response. The updated outlook reflects the activity we see today and does not include environmental emergencies that have not yet occurred. Our focus is on the priorities within our control, serving our clients, maintaining cost discipline, executing known Consulting and Treatment projects, supporting continued momentum in our testing business and converting a greater share of revenue into earnings and cash flow. That work is strengthening Onterris, and our core thesis is unchanged. Environmental challenges remain increasingly interconnected. Our clients are looking for partners who can help them navigate a series of interconnected challenges across their operations, and that's exactly where Onterris is positioned and why underlying demand remains strong. The integrated platform we've built over the past several years is allowing us to improve profitability even in a year where certain revenue streams are performing below our initial expectations. We also expect to resume disciplined bolt-on acquisitions within our valuation and leverage parameters. We believe all of these efforts will continue to maximize value for shareholders. And with that, I will turn it over to Allan to walk through the updated outlook and our financial results in greater detail.
