OKLAHOMA CITY, March 1, 2024 /PRNewswire/ -- Mammoth Energy Services, Inc. ("Mammoth" or the "Company") (NASDAQ:TUSK) today announced payment of $50.6 million from the Puerto Rico Electric Power Authority ("PREPA") for a portion of the work its wholly-owned subsidiary Cobra Acquisitions LLC ("Cobra") completed in the aftermath of Hurricane Maria. This is in addition to $13.4 million paid by PREPA in January 2024. As previously announced, on December 1, 2023, Cobra entered into an agreement to transfer approximately $54.4 million of its outstanding receivable with PREPA to SPCP Group, LLC ("SPCP Group"). The aggregate payments from PREPA in 2024 totaling $64.0 million fully satisfied the obligations to SPCP Group and resulted in Cobra receiving approximately $9.6 million in cash.

Mark Layton, Chief Financial Officer of Mammoth commented, "We're pleased to have received these payments from PREPA, which has allowed us to extinguish the liability owed to SPCP Group and collect nearly $10 million in cash. We continue to pursue payment of the outstanding amounts owed to Cobra, including the associated interest, as these payments represent only a portion of the amounts still owed to us."

In addition, today Mammoth reported financial and operational results for the fourth quarter and full year ended December 31, 2023.

Financial Overview for the Fourth Quarter and Full Year 2023:

Total revenue was $52.8 million for the fourth quarter of 2023 compared to $102.9 million for the same quarter of 2022 and $65.0 million for the third quarter of 2023. Total revenue for the full year of 2023 was $309.5 million, a decrease of 15% compared to $362.1 million in 2022.

Net loss for the fourth quarter of 2023 was $6.0 million, or $0.12 loss per diluted share, compared to net income of $4.8 million, or $0.10 per diluted share, for the same quarter of 2022 and net loss of $1.1 million, or $0.02 loss per diluted share, for the third quarter of 2023. Net loss for the full year of 2023 was $3.2 million, or $0.07 per fully diluted share, compared to net loss of $0.6 million, or $0.01 per fully diluted share for 2022.

Adjusted EBITDA (as defined and reconciled below) was $10.5 million for the fourth quarter of 2023, compared to $24.1 million for the same quarter of 2022 and $13.4 million for the third quarter of 2023. Adjusted EBITDA was $71.0 million for the full year of 2023 compared to $86.1 million for 2022.

Arty Straehla, Chief Executive Officer of Mammoth commented, "The fourth quarter proved to be challenging, largely due to additional deferred activity by exploration and production companies, commodity price fluctuations, and customer budget exhaustion. Despite the operational softness we experienced this year, 2023 marked several accomplishments for Mammoth as we completed a significant debt refinancing transaction, began receiving payments from PREPA on our outstanding receivable and entered into an agreement to monetize a portion of our outstanding PREPA receivable.

"In 2023, we entered into a new revolving credit facility agreement and a new term loan agreement, which refinanced, in full, Mammoth's indebtedness outstanding under our previous revolving credit facility. We believe these new agreements provide Mammoth with a solid liquidity base for years to come. During 2023, we also received our first payments from PREPA in more than four years totaling $22.2 million. In addition, we entered into an agreement to monetize a portion of our outstanding receivable with PREPA, which allowed us to increase liquidity and invest in our business. We used a portion of the proceeds to repay in full our outstanding borrowings under the new revolving credit facility, which currently remains undrawn. We plan to use the remainder of the proceeds to invest back into our business, which may include upgrading an additional hydraulic fracturing fleet with dual fuel capabilities. This incremental dual fuel fleet would result in three of our six fleets having dual fuel capabilities."

Commenting further, Straehla said, "We exited 2023 with a strong balance sheet and a secure financing structure that positions Mammoth for future growth. We have entered 2024 with an improving line of sight, particularly in our infrastructure and sand divisions, and we will be opportunistic in our well completions business as commodity prices improve and activity increases. I am proud of the hard work and perseverance that our teams have demonstrated across our organization. Our continued commitment to safety and high-quality standards propels our organization forward."

MAMMOTH ENERGY SERVICES, INC.

RECONCILIATION OF NON-GAAP FINANCIAL MEASURES

Adjusted EBITDA

Adjusted EBITDA is a supplemental non-GAAP financial measure that is used by management and external users of the Company's financial statements, such as industry analysts, investors, lenders and rating agencies. Mammoth defines Adjusted EBITDA as net (loss) income before depreciation, depletion, amortization and accretion expense, gains on disposal of assets, net, impairment of goodwill, stock based compensation, interest expense and financing charges, net, other (income) expense, net (which is comprised of interest on trade accounts receivable and certain legal expenses) and provision (benefit) for income taxes, further adjusted to add back interest on trade accounts receivable. The Company excludes the items listed above from net (loss) income in arriving at Adjusted EBITDA because these amounts can vary substantially from company to company within the energy service industry depending upon accounting methods and book values of assets, capital structures and the method by which the assets were acquired. Adjusted EBITDA should not be considered as an alternative to, or more meaningful than, net (loss) income or cash flows from operating activities as determined in accordance with GAAP or as an indicator of Mammoth's operating performance or liquidity. Certain items excluded from Adjusted EBITDA are significant components in understanding and assessing a company's financial performance, such as a company's cost of capital and tax structure, as well as the historic costs of depreciable assets. Mammoth's computations of Adjusted EBITDA may not be comparable to other similarly titled measures of other companies. The Company believes that Adjusted EBITDA is a widely followed measure of operating performance and may also be used by investors to measure its ability to meet debt service requirements.

The following tables provide a reconciliation of Adjusted EBITDA to the GAAP financial measure of net (loss) income on a consolidated basis and for each of the Company's segments (in thousands):

Adjusted Net (Loss) Income and Adjusted (Loss) Earnings per Share

Adjusted net (loss) income and adjusted basic and diluted (loss) earnings per share are supplemental non-GAAP financial measures that are used by management to evaluate the Company's operating and financial performance. Mammoth defines adjusted net (loss) income as net (loss) income before impairment of goodwill. Mammoth defines adjusted basic and diluted (loss) earnings per share as (loss) earnings per share before the effects of impairment of goodwill and impairment of other long-lived assets. Management believes these measures provide meaningful information about the Company's performance by excluding certain non-cash charges, such as impairment of goodwill and impairment of other long-lived assets, that may not be indicative of the Company's ongoing operating results. Adjusted net (loss) income and adjusted (loss) earnings per share should not be considered in isolation or as a substitute for net (loss) income and (loss) earnings per share prepared in accordance with GAAP and may not be comparable to other similarly titled measures of other companies. The following tables provide a reconciliation of adjusted net (loss) income and adjusted (loss) earnings per share to the GAAP financial measures of net (loss) income and (loss) earnings per share for the periods specified.
