Montauk Renewables Announces First Quarter 2024 Results

PITTSBURGH, PENNSYLVANIA – May 9, 2024—Montauk Renewables, Inc. (“Montauk” or “the Company”) (NASDAQ: MNTK), a renewable energy company specializing in the management, recovery, and conversion of biogas into renewable natural gas (“RNG”), today announced financial results for the first quarter ended March 31, 2024.

First Quarter Financial Highlights:

• Revenues of $38.8 million, increased 102.5% compared to the first quarter of 2023

• Net Income of $1.9 million, increased 148.8% compared to the first quarter of 2023

• Non-GAAP Adjusted EBITDA of $9.5 million, increased 212.7% compared to the first quarter of 2023

• RNG production of 1.4 million MMBtu, increased 4.4% compared to the first quarter of 2023

• RINs Sold of 7.9 million, increase of 167.5% compared to the first quarter of 2023

Our profitability is highly dependent on the market price of Environmental Attributes, including the market price for RINs. As we self-market a significant portion of our RINs, a strategic decision not to commit to transfer available RINs during a period will impact our operating revenue and operating profit. We made a strategic determination to not transfer all available D3 RINs generated and available for transfer during the first quarter of 2024. As of result of this strategic decision, we have approximately 3,351 RINs in inventory from 2024 RNG production. In April 2024, we signed a second feedstock supply agreement which includes additional access to hog spaces with this individual feedstock supplier. When added to the first feedstock supply agreement, which was signed in the fourth quarter of 2023, we believe we are on pace to target the 120 thousand hog spaces which will provide sufficient feedstock under our Duke Energy REC agreement. Additionally, in the first quarter of 2024, we successfully commissioned the last expansion of our Pico digestion capacity project. With the increased digestion capacity, we produced approximately 39% more MMBtu during the first quarter of 2024 compared to the first quarter of 2023.

First Quarter Financial Results

Total revenues in the first quarter of 2024 were $38.8 million, an increase of $19.6 million (102.5%) compared to $19.2 million in the first quarter of 2023. The increase is primarily related to an increase in self-monetized RINs in the first quarter of 2024 as a result of our strategic decision in the first quarter of 2023 to not self-market a significant amount of RINs from 2023 RNG production due to 2023 D3 RIN index price volatility. Additionally, an increase in realized RIN pricing of 61.7% during the first quarter of 2024 as compared to the first quarter of 2023 contributed to the increase in revenues. Our RNG Operating and maintenance expenses in the first quarter of 2024 were $12.1 million, an increase of $0.8 million (7.0%) compared to $11.3 million in the first quarter of 2023. The primary driver of this increase was related to timing of preventative maintenance expenses at our Rumpke and Atascocita facilities. Our Renewable Electricity Generation operating and maintenance expenses in the first quarter of 2024 were $2.3 million, a decrease of $0.6 million (19.9%) compared to $2.9 million in the first quarter of 2023, primarily due to the reversal of our asset retirement obligation liability related to the sale of our Security facility. Total general and administrative expenses in the first quarter of 2024 were $9.4 million, flat as compared to $9.5 million in the first quarter of 2023. Operating income in the first quarter of 2024 was $2.4 million, an increase of $16.5 million (116.7%) compared to an operating loss of $14.2 million in the first quarter of 2023. Net income in the first quarter of 2024 was $1.9 million, an increase of $5.6 million (148.8%) compared to a net loss of $3.8 million in the first quarter of 2023.

First Quarter Operational Results

We produced approximately 1.4 million Metric Million British Thermal Units (“MMBtu”) of RNG in the first quarter of 2024, an increase of less than 0.1 million compared to 1.4 million in the first quarter of 2023. We want to highlight that our Pico facility produced 9 MMBtu more in the first quarter of 2024 as compared to the first quarter of 2023 related to the commissioning our digestion expansion project. We produced approximately 54 thousand megawatt hours (“MWh”) in Renewable Electricity in the first quarter of 2024, an increase of 8 thousand MWh compared to 46 thousand MWh produced in the first quarter of 2023. Our Security facility produced approximately 3 thousand MWh more in the first quarter of 2024 compared to the first quarter of 2023 as a result of prior period engine maintenance. Our Bowerman facility produced approximately 3 thousand MWh more in the first quarter of 2024 compared to the first quarter of 2023 primarily related to timing of preventative engine maintenance.

Reaffirmed 2024 Full Year Outlook

• RNG revenues are expected to range between $195 and $215 million

• RNG production volumes are expected to range between 5.8 and 6.1 million MMBtu

• Renewable Electricity revenues are expected to range between $18.0 and $19.0 million

• Renewable Electricity production volumes are expected to range between 190 and 200 thousand MWh

Use of Non-GAAP Financial Measures

This press release and the accompanying tables include references to EBITDA and Adjusted EBITDA, which are Non-GAAP financial measures. We present EBITDA and Adjusted EBITDA because we believe the measures assist investors in analyzing our performance across reporting periods on a consistent basis by excluding items that we do not believe are indicative of our core operating performance.

In addition, EBITDA and Adjusted EBITDA are financial measurements of performance that management and the board of directors use in their financial and operational decision-making and in the determination of certain compensation programs. EBITDA and Adjusted EBITDA are supplemental performance measures that are not required by or presented in accordance with GAAP. EBITDA and Adjusted EBITDA should not be considered alternatives to net (loss) income or any other performance measure derived in accordance with GAAP, or as an alternative to cash flows from operating activities or a measure of our liquidity or profitability.
