Financial Data and Key Metrics Changes - Total revenue for Q1 2023 was $131.4 million, a decrease from $134.7 million in the prior year quarter, primarily due to lower demand for COVID-19-related services and project timing in the remediation and reuse segment [16][17] - Consolidated adjusted EBITDA was $16.6 million, representing 12.6% of revenue, an increase of 15.2% from $14.4 million in the prior year, with adjusted EBITDA margins improving from 11.2% to 12.8% [17][22] - The company raised its full-year 2023 EBITDA outlook to a range of $70 million to $76 million, up from the previous range of $68 million to $74 million, indicating low double-digit growth and margin expansion [22] Business Segment Performance - In the Assessment Permitting and Response segment, revenue increased 14.5% year-over-year to $52.2 million, driven by organic growth and acquisitions, with adjusted EBITDA increasing 48.2% to $14.3 million, reflecting a margin of 27.3% [39] - The Measurement and Analysis segment saw a revenue increase of 7% to $42.5 million, primarily due to strong organic growth, with adjusted EBITDA margin rising to 15.6% from 13.7% in the prior year [40] - The Remediation and Reuse segment experienced a revenue decline to $36.7 million from $49.3 million in the prior year quarter, attributed to the winding down of high-value projects, although this was partially offset by revenues from acquisitions [1][6] Market Data and Key Metrics Changes - The U.S. EPA's focus on PFAS and methane emissions is expected to drive demand for the company's services, particularly in environmental consulting and testing [8][9][10] - The company is well-positioned to assist clients in navigating the evolving regulatory landscape, which is expected to enhance demand for its services [11] Company Strategy and Industry Competition - The company is focusing on acquisitions to enhance its service offerings, with a reduced cadence last year due to strong organic growth, but expects to capitalize on its M&A pipeline this year [2] - Investments in R&D are anticipated to yield significant returns, particularly in greenhouse gas measurement, PFAS remediation, and renewable energy sectors [43] Management's Comments on Operating Environment and Future Outlook - Management expressed confidence in the company's ability to solve environmental challenges and create value for shareholders, citing strong cash flow and a robust balance sheet [3][13] - The company remains insulated from political and economic swings, with a strong outlook for organic growth across its service lines despite anticipated moderation in certain segments [3][32] Other Important Information - The company’s leverage ratio as of March 31, 2023, was 1.4x, with minimal exposure to rising interest rates due to cash reserves and interest rate swaps [41] - The Series A2 preferred stock has no maturity date, providing flexibility in capital structure [21] Q&A Session Summary Question: Can you provide details on the Matrix Solutions acquisition? - The acquisition is in the process of shareholder vote and is expected to close in the second quarter, but it will not materially impact the overall profile as CTEH did [46][47] Question: What is the market opportunity in Canada? - The company sees significant opportunities in Canada due to favorable environmental policies and expects strong client-based opportunities across both Canada and the U.S. [48][62] Question: How durable are the margins in the Assessment and Permitting segment? - The margins are expected to be durable, with a run rate of $75 million to $95 million in revenue and approximately 25% EBITDA margins [51] Question: Should we expect growth in the remediation and reuse revenue for the full year? - The company anticipates flat growth for 2023 compared to 2022, with a strong outlook for 2024 to 2025 [54][55] Question: Is there any sensitivity around CapEx projects in the assessment and permitting area? - The company is not significantly exposed to discretionary spending and remains confident in its fundamental work despite broader economic uncertainties [69]
