Thanks, Vijay. Our solid overall first quarter performance reflects the strength of our business model and ongoing demand for our environmental solutions. As Vijay mentioned, we are especially pleased with our strong year-over-year margin performance at an operating segment level as a result of the favorable business mix, the in-demand nature of our services and the early returns from our pricing actions. We also benefited from M&A which we expect to be more meaningful this year, given the resumption of our typical M&A cadence as demonstrated by our recent acquisitions since the beginning of the year. Moving to our first quarter performance on Slide 8. Total revenue for the first quarter was $131.4 million compared to $134.7 million in the prior year quarter, primarily due to lower demand for COVID-19-related services provided by CTEH, lower revenues in a discontinued lab and the timing of projects in our remediation and reuse segment. Excluding revenue from COVID-19-related services and discontinued businesses, revenue was up 17.2% year-over-year, given strong organic growth in our assessment permitting and response and measurement and analysis segments, an increase in CTEH environmental response revenues and the contribution of acquisitions. First quarter consolidated adjusted EBITDA was $16.6 million and represented 12.6% of revenue. Excluding discontinued businesses and including start-up losses which we no longer add back, consolidated adjusted EBITDA of $16.6 million compares to $14.4 million in the prior year, an increase of 15.2% and consolidated adjusted EBITDA margins improved from 11.2% in Q1 2022 to 12.8% in the current year. As we've highlighted on prior calls, Montrose's performance needs to be assessed annually. This is how we evaluate the business due to the stronger predictability of the business on an annual basis. This is consistent with how we hire staff, allocate resources and manage the company. Turning to our business segments on Slides 9 and 10. We are primarily focused on meeting or exceeding our targets for adjusted EBITDA dollars and cash flow conversion and we remain pleased with our results. We also continue to drive margin improvement at the operating level and we were pleased to see operating segment's adjusted EBITDA margin increased 190 basis points to 19.7% compared to 17.8% in the prior year quarter, mainly due to the transition of CTEH away from COVID-19 services, strong demand for our environmental testing services and the benefits of pricing which more than offset the expected decline in remediation and reuse revenue. Excluding results from discontinued businesses and including start-up losses in the prior year, operating segment's adjusted EBITDA margin increased 290 basis points year-over-year. Beginning this year, organic revenue growth for total revenue and for the assessment, permitting and response segment excludes CTEH to provide a better sense of underlying performance for that segment and our business without CTEH variability. In our assessment, permitting and response segment, revenue increased 14.5% year-over-year to $52.2 million. The year-over-year increase was driven primarily by organic growth and, to a lesser extent, the positive contributions from acquisitions. Within CTEH, a significant increase in environmental response revenues fully offset the anticipated steep decline in COVID-19-related services. AP&R segment adjusted EBITDA increased 48.2% year-over-year to $14.3 million, or 27.3% of revenue, up from 21.1% in the prior year quarter, reflecting the benefits of organic growth and the favorable CTEH [ph] revenue mix, given environmental response revenues generate higher margins than COVID-19-related revenues and higher aggregate margins across our other businesses within this segment. In our measurement & analysis segment, revenue increased 7% to $42.5 million, primarily attributable to strong organic growth. While M&A segment adjusted EBITDA increased slightly, the decline as a percent of revenue was mainly due to a decrease in revenues and adjusted EBITDA from a discontinued lab. Excluding the impact of the discontinued lab and including start-up losses in the prior year, segment adjusted EBITDA margin increased to 15.6% from 13.7% in the prior year, reflecting strong demand for our testing services and the benefits from our pricing actions. In our remediation and reuse segment, revenues were $36.7 million compared to $49.3 million in the prior year quarter as a result of the winding down of certain high-dollar-value projects. The decrease was partially offset by revenues from acquisitions. The decrease in R&R segment adjusted EBITDA as a percentage of revenue was a result of lower revenues. Moving to our capital structure on Slide 11. First quarter cash flow from operating activities was $3 million compared to cash used in operations of $18.3 million in the prior year quarter. Cash used in operations in the prior year includes payment of acquisition-related consideration of $19.5 million. Excluding this acquisition-related payment, cash provided by operating activities increased by $1.8 million year-over-year compared to adjusted cash from operating activities of $1.2 million in the prior year quarter. This year-over-year increase was primarily due to an increase in working capital in the current period of $9.7 million versus an increase in working capital in the prior year period of $12.5 million, partially offset by lower earnings before noncash items of $0.9 million. These strong operating cash flows reflect our ongoing focus on balancing the generation of cash with investments in technology, R&D and corporate infrastructure to ensure continued scalability. Our leverage ratio as of March 31, 2023 which includes the impact of recent acquisitions and the acquisition-related contingent earn-out obligations payable in cash, was at 1.4x. The cash we have on the balance sheet and the interest rate swap we put in place in January 2022 have resulted in almost no exposure to rising interest rates at current borrowing levels. Our Series A2 preferred stock has no maturity date. We have the option but not an obligation, to redeem the preferred shares at any time for cash. The prepayment penalty expired in April of this year. We view this preferred equity instrument as favorable to the value creation potential in the business, given its flexible dynamics and the fixed nature of the dividend in a rising interest rate environment. If you include the $182 million balance of the Series A2 equity and our market cap, our total equity capitalization stands at approximately $1.3 billion. Moving to our improved full-year outlook on Slide 13. We have had a strong start to the year. Based on EBITDA performance in the first quarter and momentum in our overall business, we are raising our full-year growth outlook for consolidated adjusted EBITDA to be in the range of $70 million to $76 million compared to the prior range of $68 million to $74 million. Our higher consolidated adjusted EBITDA outlook represents low double-digit growth and margin expansion over the prior year. Our expectation for revenue is unchanged, in the range of $550 million to $600 million, representing mid- to high single-digit growth for the full year. Our revenue and consolidated adjusted EBITDA outlook does not include any benefit from future acquisitions that have not been completed. In conclusion, our improved 2023 outlook reflects our confidence in our ability to execute against our growth strategy. The in-demand nature of our unique environmental solutions, expanding customer relationships, solid customer retention and cross-selling success all position us well to expand our market share as a leader in the environmental services space. Over the longer term, our investments in R&D are expected to generate significant returns as we look to capture end market and regulatory tailwinds in the greenhouse gas measurement and mitigation, PFAS remediation, renewable energy and carbon capture spaces. Thank you all for joining us today and for your continued interest in Montrose. We look forward to the opportunities we see ahead and updating you on our progress next quarter. Operator, we are ready to open the line to questions.
