Mammoth Energy Services, Inc.：高管交易动态
Mammoth Energy Services, Inc.属于能源行业。其高管的申报经由SEC (Form 4)发布。过去一年（2025年10月22日至2026年10月22日），共有13份申报出自4位高管。
期内所有公开市场交易均为买入：3位高管共进行7笔买入，金额€915万，没有一笔卖出。在市场上买入意味着按当时价格投入个人资金，这与以股份形式获得报酬截然不同。2026年6月22日由Wexford Capital LP公布的买入金额为€910万，是期内最大的一笔。参与买入的有3位高级管理人员等。
其中1笔买入发生在公司另一位高管买入后的30天之内。多位不同高管在短时间内买入同一只股票，称为集群买入，这种情形比单笔买入更受研究者关注。有记录的最近一笔买入公布于2026年9月17日，即52天前。通过SEC (Form 4)，交易与发布之间的中位间隔为5天。在美国，内部人须在交易后两个工作日内提交Form 4表格。
十二个月内共13份申报，低于我们在同一交易所跟踪的3,171家公司的中位数（24份申报）。回溯至覆盖起点2016年，高管共申报29笔买入和40笔卖出。根据10-K年报，截至2025年12月31日的财年营收达4429.2万 USD，净利润为459.7万 USD。
这些数据整理自监管申报（来源：SEC (Form 4)），仅描述高管的操作，并非投资推荐。

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.
