About Mammoth Energy Services, INC.

Mammoth Energy Services, Inc. is a U.S.-based energy services company listed on the NASDAQ under the ticker TUSK in the United States. The company has historically positioned itself as an integrated provider to the power grid and to parts of the oilfield services value chain. Its headquarters are in Oklahoma City, Oklahoma, which fits its operational footprint in energy infrastructure and field services. From a business perspective, Mammoth has operated across several complementary lines: electric transmission and distribution infrastructure services, equipment rentals, sand services, remote accommodations, and, historically, drilling and completion-related services. Recent disclosures show a meaningful portfolio reshaping. In 2025, the company completed the sale of its infrastructure services subsidiaries involved in transmission and distribution work and also sold its hydraulic fracturing equipment and related assets. Those divestitures materially reduced exposure to more capital-intensive and cyclical businesses and reflect a broader strategic reset. More recently, management has emphasized capital allocation and has highlighted investments in aviation as a growth-oriented platform. Competitively, Mammoth is best viewed as a niche small-cap services provider rather than a large-scale industry leader. It does not have the breadth or scale of major global oilfield service groups, but it can compete where specialized equipment, flexibility, and project execution matter. The company’s more streamlined balance sheet is also an important part of the investment case. In its first-quarter 2026 update released on May 11, 2026, Mammoth said it ended the quarter debt-free with approximately $125 million of cash, cash equivalents, and marketable securities, which gives it financial flexibility to invest in the business or return capital to shareholders. Geographically, Mammoth’s business is primarily U.S.-focused, serving utilities and energy customers across domestic markets. Its remote accommodation activities also suggest exposure to industrial and energy regions where workforce housing and logistical support are needed. Recent highlights include the 2025 asset sales, the company’s continued portfolio rationalization, and its May 2026 earnings release. For French-speaking investors, Mammoth is therefore a U.S. NASDAQ-listed restructuring story: a smaller, specialized energy services company trying to redeploy capital after shrinking its legacy service base. The key questions now are execution, cash deployment, and whether new investments can create durable shareholder value.
