MONTROSE ENVIRONMENTAL GROUP ANNOUNCES STRONG THIRD QUARTER 2023 RESULTS

  • Revenue Increases 28.9% with Continued Margin Expansion -

  • Net Loss of $(7.5) Million; Consolidated Adjusted EBITDA1 Increases 36.2% to $23.3 Million -

  • Significant Increase in Cash Flow from Operations -

Little Rock, Arkansas (November 7, 2023) – Montrose Environmental Group, Inc. (the “Company,” “Montrose” or “MEG”) (NYSE: MEG) today announced results for the third quarter ended September 30, 2023.

Montrose Chief Executive Officer and Director, Vijay Manthripragada, commented, “We are proud to report another quarter of exceptional results. The surge in organic growth across many of our service lines and the contribution from the Matrix acquisition in Canada helped drive record levels of quarterly revenue and Consolidated Adjusted EBITDA1. We are particularly pleased with the continued improvement in our margin profile and robust operating cash flow generation, which validate the strategic portfolio shift in our Remediation and Reuse segment, our pricing strategy, and the ongoing integration of the Matrix team. Our recent acquisitions have been very additive and continue to provide scale, expertise and geographic reach.”

Mr. Manthripragada continued, “As we look to the full year 2023, we are reiterating Revenue and Consolidated Adjusted EBITDA1 guidance. The regulatory landscape, with new and pending rules on methane leak detection and air emissions standards, continues to generate tailwinds. Additionally, the private sector’s commitment to environmental stewardship and resiliency, through initiatives such as net-zero commitments and environmental justice, is creating opportunities throughout our comprehensive service offerings. Our history has shown that our business is resilient across economic and political cycles and despite a very challenging macro-economic backdrop, our teams continue to deliver as we have shown all year. We remain very optimistic about our outlook and incredibly grateful to all of our colleagues around the world.”

_______________________________

(1) Consolidated Adjusted EBITDA, Adjusted Net Income (Loss) and Adjusted Net Income (Loss) per Share are non-GAAP measures. See the appendix to this release for a discussion of these measures, including how they are calculated and the reasons why we believe they provide useful information to investors, and a reconciliation for historical periods to the most directly comparable GAAP measures.

Third Quarter 2023 Results

Total revenue in the third quarter of 2023 was $167.9 million compared to $130.3 million in the prior year quarter, an increase of 28.9%. The increase in revenues was primarily due to the acquisition of Matrix, organic growth in the Assessment, Permitting and Response segment, organic growth in the Measurement and Analysis segment, and an increase in CTEH revenues, partially offset by lower revenues in a specialty lab that is being discontinued and our Remediation and Reuse segment driven by the timing of projects and a strategic shift in our biogas business to focus on higher margin services. Excluding revenue from the legacy O&M contracts, and the specialty lab being discontinued, of $2.0 million and $4.6 million, in the third quarters of 2023 and 2022, respectively, revenue in the third quarter of 2023 was $165.9 million compared to $125.7 million in the prior year quarter, an increase of 32.0% over the prior year period.

Net loss was $(7.5) million, or a loss of $(0.39) per share, in the third quarter of 2023 compared to a net loss of $(5.7) million, or a loss of $(0.33) per share, in the prior year quarter. The year-over-year increase was primarily attributable to an increase in the fair value adjustment on our Series A-2 preferred stock in the current year, compared to a fair value gain on our interest rate swap in the prior year, as well as a higher interest and tax expense in the current year, partially offset by improved operating performance.

Adjusted Net Income1 was $9.4 million, and Adjusted Net Income per Share1 was $0.18, in the third quarter of 2023 compared to Adjusted Net Income1 of $7.8 million, and Adjusted Net Income per Share1 of $0.12 in the prior year quarter. The year-over-year increase was primarily attributable to an increase in revenues.

Third quarter 2023 Consolidated Adjusted EBITDA1 was $23.3 million, representing 13.9% of revenue, compared to $17.1 million or 13.1% of revenue in the prior year quarter, primarily due to higher revenues driven by organic growth and acquisitions.

First Nine Months 2023 Results

Total revenue in the first nine months of 2023 increased 13.2% to $458.5 million compared to $404.9 million in the prior year period. The increase in revenues was primarily due to organic growth in the Assessment, Permitting and Response, organic growth in the Measurement and Analysis segment, an increase in CTEH revenues, and the contributions of acquisitions completed since the beginning of 2022, partially offset primarily by lower revenues in a specialty lab that is being discontinued and our Remediation and Reuse segment driven by the timing of projects and a strategic shift in our biogas business to focus on higher margin services. Excluding revenue from the legacy O&M contracts, and the specialty lab being discontinued, of $5.9 million and $16.0 million, in the nine-month periods of 2023 and 2022, respectively, revenue in the first nine months of 2023 was $452.6 million compared to $388.9 million in the prior year, an increase of 16.4% over the prior year period.

Net loss was $(29.4) million, or $(1.39) per share, in the first nine months of 2023 compared to a net loss of $(21.0) million, or $(1.12) per share, in the prior year period. The year-over-year change was primarily attributable to changes in the fair value of business acquisition contingencies, the net impact of fair value adjustments related to our Series A-2 preferred stock conversion option and interest rate swaps in the current year compared to the prior year, as well as higher interest expense and higher stock-based compensation in the current year.

Adjusted Net Income1 was $21.6 million, and Adjusted Net Income per Share1 was $0.31, in the first nine months of 2023 compared to Adjusted Net Income1 of $18.7 million, and Adjusted Net Income per Share1 of $0.22, in the prior year period.

Consolidated Adjusted EBITDA1 for the first nine months of 2023 was $61.1 million, representing 13.3% of revenue, compared to $48.4 million, or 12.0% of revenue, in the prior year period, an increase of 26.3%. The increase in Adjusted Net Income1, Adjusted Net Income per Share1, and Consolidated Adjusted EBITDA1 was primarily due to higher revenues.

Operating Cash Flow, Liquidity and Capital Resources

Cash provided by operating activities for the first nine months ended September 30, 2023 was $41.5 million compared to cash provided by operating activities of $8.2 million in the prior year period, an increase of $33.3 million, or 407.9%. Cash flow from operations includes payment of contingent consideration of $0.6 million and $19.5 million in the current and prior year periods, respectively. Excluding these acquisition-related contingent earnout payments, which are not part of day-to-day operations, cash flow from operating activities was $42.1 million compared to $27.7 million in the prior year period, an increase of $14.4 million, or 52.0%.

As of September 30, 2023, we had total debt, before debt issuance costs, of $168.1 million and $148.2 million of liquidity, including $23.2 million of cash and $125.0 million of availability on our revolving credit facility. At our current leverage ratio and inclusive of our fixed rate on $170.0 million of debt under our interest rate swaps, our weighted average interest rate was 4.4% as of September 30, 2023.

As of September 30, 2023, Montrose’s leverage ratio under its credit facility, which includes recently completed acquisitions and acquisition-related contingent earnout payments that may become payable in cash, was 1.9 times.

Full Year 2023 Outlook

The Company reiterates its full year 2023 Revenue and Consolidated Adjusted EBITDA1 outlook. The Company expects Revenue to be in the range of $590 million to $640 million. Consolidated Adjusted EBITDA1 is expected to be in the range of $75 million to $81 million for the full year 2023.

The revenue and Consolidated Adjusted EBITDA1 outlook does not include any benefit from future acquisitions that have not yet been completed.

Non-GAAP Financial Information

In addition to our results under GAAP, in this release we also present certain other supplemental financial measures of financial performance that are not required by, or presented in accordance with, GAAP, including, Consolidated Adjusted EBITDA, Adjusted Net Income (Loss) and Adjusted Net Income (Loss) per Share. We calculate Consolidated Adjusted EBITDA as net income (loss) before interest expense, income tax expense (benefit) and depreciation and amortization, adjusted for the impact of certain other items, including stock-based compensation expense and acquisition-related costs, as set forth in greater detail in the table below. We calculate Adjusted Net Income (Loss) as net income (loss) before amortization of intangible assets, stock-based compensation expense, fair value changes to financial instruments and contingent earnouts, discontinuing specialty lab, and other gain or losses, as set forth in greater detail in the table below. Adjusted Net Income (Loss) per Share represents Adjusted Net Income (Loss) attributable to stockholders divided by the weighted average number of shares of common stock outstanding during the applicable period.

Consolidated Adjusted EBITDA is one of the primary metrics used by management to evaluate our financial performance and compare it to that of our peers, evaluate the effectiveness of our business strategies, make budgeting and capital allocation decisions and in connection with our executive incentive compensation. Adjusted Net Income (Loss) and Adjusted Net Income (Loss) per Share are useful metrics to evaluate ongoing business performance after interest and tax. These measures are also frequently used by analysts, investors and other interested parties to evaluate companies in our industry. Further, we believe they are helpful in highlighting trends in our operating results because they allow for more consistent comparisons of financial performance between periods by excluding gains and losses that are non-operational in nature or outside the control of management, and, in the case of Consolidated Adjusted EBITDA, by excluding items that may differ significantly depending on long-term strategic decisions regarding capital structure, the tax jurisdictions in which we operate and capital investments.

These non-GAAP measures do, however, have certain limitations and should not be considered as an alternative to net income (loss), earnings (loss) per share or any other performance measure derived in accordance with GAAP. Our presentation of Consolidated Adjusted EBITDA, Adjusted Net Income (Loss) and Adjusted Net Income (Loss) per Share should not be construed as an inference that our future results will be unaffected by unusual or non-recurring items for which we may make adjustments. In addition, Consolidated Adjusted EBITDA, Adjusted Net Income (Loss) and Adjusted Net Income (Loss) per Share may not be comparable to similarly titled measures used by other companies in our industry or across different industries, and other companies may not present these or similar measures. Management compensates for these limitations by using these measures as supplemental financial metrics and in conjunction with our results prepared in accordance with GAAP. We encourage investors and others to review our financial information in its entirety, not to rely on any single measure and to view Consolidated Adjusted EBITDA, Adjusted Net Income (Loss) and Adjusted Net Income (Loss) per Share in conjunction with the related GAAP measures.

Additionally, we have provided estimates regarding Consolidated Adjusted EBITDA for 2023. These projections account for estimates of revenue, operating margins and corporate and other costs. However, we cannot reconcile our projection of Consolidated Adjusted EBITDA to net income (loss), the most directly comparable GAAP measure, without unreasonable efforts because of the unpredictable or unknown nature of certain significant items excluded from Consolidated Adjusted EBITDA and the resulting difficulty in quantifying the amounts thereof that are necessary to estimate net income (loss). Specifically, we are unable to estimate for the future impact of certain items, including income tax (expense) benefit, stock-based compensation expense, fair value changes and the accounting for the issuance of the Series A-2 preferred stock. We expect the variability of these items could have a significant impact on our reported GAAP financial results.

In this release we also reference our organic growth. We define organic growth as the change in revenues excluding revenues from our environmental emergency response business, from acquisitions for the first twelve months following the date of acquisition and excluding revenues from businesses held for sale, disposed of or discontinued. As a result of the potential annual volatility in CTEH’s revenues due to the emergency response aspect of their business, we will no longer be including CTEH revenues in the calculation of organic growth. Management uses organic growth as one of the means by which it assesses our results of operations. Organic growth is not, however, a measure of revenue growth calculated in accordance with U.S. generally accepted accounting principles, or GAAP, and should be considered in conjunction with revenue growth calculated in accordance with GAAP. We have grown organically and expect to continue to do so.
