Thanks, Vijay. We are very pleased to have delivered strong third quarter results. Our resilient performance throughout the year thus far, reflects the themes we've discussed since becoming a public company over three years ago as new environmental regulations and corporate mandates continue to drive demand for our unique environmental solutions. Our business remains strong and continues to grow given our successful execution of attractive M&A, ongoing cross selling successes, and expanding customer relationships. Moving to our revenue performance on slide eight. We saw organic growth across many of our service lines helped drive revenues to record levels in the third quarter. Our third quarter revenues increased 28.9% to $167.9 million compared to the prior year quarter. Year-to-date revenues were up 13.2% versus the prior year period to $458.5 million. The primary driver of revenue growth in both periods was the positive contributions from acquisitions including Matrix, strong organic growth in our Assessment, Permitting and Response and Measurement and Analysis segments, and an increase in CTEH revenues. This was partially offset by lower revenues in a specialty lab that has been discontinued and the change in our Remediation and Reuse segment given the timing of projects and a strategic shift in our biogas business to focus on higher margin, lower revenue services. Growth in our year-to-date revenue was also impacted by our planned exit from legacy O&M contracts in 2022. Excluding revenue from discontinued businesses, revenue was up 32% to $165.9 million in the third quarter and was up 16.4% to $452.6 million year-to-date. Looking at our consolidated adjusted EBITDA performance on Slide 9, third quarter consolidated adjusted EBITDA was a record $23.3 million or 13.9% of revenue. This compares to consolidated adjusted EBITDA of $17.1 million or 13.1% of revenue in the prior year quarter. The year-over-year improvement was driven by higher revenues and higher operating margins, driven in part by the benefit of pricing. Year-to-date, consolidated adjusted EBITDA was $61.1 million or 13.3% of revenue compared to consolidated adjusted EBITDA of $48.4 million or 12% of revenue in the prior year. With that said, I'll reemphasize that Montrose's performance needs to be assessed annually as quarterly results are not always indicative of annual performance. Turning to our business segments on slides 10 and 11. As we previously highlighted, we remain primarily focused on meeting or exceeding our target for adjusted EBITDA dollars and operating cash flow generation with the longer-term goal of optimizing our margin profile. To that end we were pleased to see the impacts of shifts through our service portfolio, which helped contribute to the increase in operating segments, adjusted EBITDA margin to 19.5%. In our Assessment, Permitting and Response segment revenues increased 22.8% year-over-year to $57 million. The year-over-year increase was driven primarily by organic growth, growth in revenues from CTEH, and to a lesser extent, the positive contributions from acquisition. CETH is entirely in this segment so that business' increase in environmental response revenues are fully captured here. AP&R segment adjusted EBITDA increased 51.5% year-over-year to $14.9 million or 26.1% of revenue, up from 21.2% in the prior year quarter, reflecting the benefits of organic growth, favorable CTEH revenue mix, and higher aggregate margins across our other businesses within the segment. In our Measurement and Analysis segment revenue increased 15.3% to $50.5 million primarily attributable to double digit organic growth as well as the benefits from acquisitions completed subsequent to the end of the prior year quarter. M&A segment's adjusted EBITDA increased 22% to $10.4 million or 20.5% of revenue, up from 19.4% in the prior year quarter, reflecting strong demand for our testing services and the benefits from our pricing action. In our Remediation and Reuse segment revenues increased 50.6% to $60.5 million, primarily due to the acquisition of Matrix and partially offset by the anticipated decline in revenues from certain large water treatment projects and the recent pivot in our biogas business to focus on higher margin, lower revenue project. The decrease in R&R segment's adjusted EBITDA as a percentage of revenue was due to lower water treatment revenues and the dilutive impact of Matrix, partially offset by the higher contribution margins within our biogas business. Our margin optimization efforts are well on track at Matrix and we expect to see low to mid-teens adjusted EBITDA margins by the end of 2024, up from low-single digits at the time of acquisition. Moving to our capital structure on slide 12. Year-to-date cash flow from operating activities was $41.5 million, which improved compared to cash provided by operating activities of $8.2 million in the prior year period. Cash flow from operations includes the payment of acquisition related contingent consideration of $0.6 million in the current year and $19.5 million in the prior year respectively. Excluding these acquisition-related payments, cash from operating activities was $42.1 million in the first nine months of 2023 compared to cash from operating activities of $27.7 million in the first nine months of 2022, an increase of $14.4 million and representing an adjusted EBITDA to operating cash flow conversion of 69%. The year-over-year increase in operating cash flows was driven primarily by a lower working capital build and higher earnings before non-cash items compared to the prior year period. These strong operational 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 September 30, 2023, which includes the impact of acquisition related contingent earn-out obligations payable in cash was at a healthy 1.9 times. Our current leverage ratio and inclusive of our fixed rate on $170 million of debt under our interest rate swaps, our weighted average interest rate under our credit facility was 4.4% as of September 30, 2023 with no exposure to rising interest rates at current borrowing levels. Our Series A-2 preferred stock has no maturity date and we have the option, but not the obligation to redeem the preferred shares at any time for cash. The holder has the option to convert up to $60 million to common equity in April of next year. We view this preferred equity instrument 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 of the Series A-2 equity in our market cap, our total equity capitalization stands at approximately $948 million. Moving to our reiterated full-year outlook on Slide 14. Based on our strong performance so far in 2023 and the expectation for CTEH business to return to run rate levels during the fourth quarter, we reiterate our outlook for full-year 2023 revenues to be in the range of $590 million to $640 million, and for consolidated adjusted EBITDA to be in the range of $75 million to $81 million. Our revenue and consolidated adjusted EBITDA outlook for the full-year continues to represent double-digit growth and margin expansion over the prior year. As we begin to look ahead to next year, we anticipate strong organic growth in 2024 and we'll provide a more fulsome outlook next quarter. In summary, demand for our environmental solutions remains robust and our reaffirmed outlook for 2023 represents our optimism in the positive trajectory of our business. We remain as confident as ever in our ability to deliver shareholder value through our best-in-class suite of environmental solutions and to capitalize on end market and regulatory tailwinds. 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 lines to questions.
