[144] Mammoth Energy Services, Inc. SEC Filing

Rhea-AI Filing Summary

Mammoth Energy Services, Inc. (TUSK) reports a proposed insider sale under Rule 144: a director filed to sell 102,178 common shares with an aggregate market value of $231,000 on Nasdaq through Sanford C. Bernstein & Co., LLC, with an approximate sale date of 08/12/2025. The filing shows the shares were received as director compensation on four dates: 12/13/2021, 06/02/2022, 06/12/2023 and 06/10/2024; payment for the proposed sale is listed as cash.

The company has 48,130,000 shares outstanding, so the proposed sale represents about 0.21% of outstanding shares. The filer reports nothing to report for securities sold in the past three months and includes the standard representation that they are not aware of any undisclosed material adverse information about the issuer.

Insights

Financial Analyst

TL;DR An insider is seeking to sell a small number of shares (≈0.21% of outstanding) received as director compensation; impact appears minimal.

The Form 144 discloses a proposed sale of 102,178 common shares for $231,000 through Sanford C. Bernstein on Nasdaq, derived from director compensation awarded across four dates. With 48.13 million shares outstanding, the transaction size is modest relative to market capitalization and unlikely to materially affect valuations or liquidity. The filing notes no sales in the prior three months and specifies cash proceeds.

Corporate Governance Expert

TL;DR Routine Rule 144 notice for a director compensation-based sale; governance disclosures appear standard and non-material.

The notice documents an insider complying with Rule 144 procedures by reporting a proposed sale and confirming no undisclosed material adverse information. The broker and sale date are specified, and acquisition history is shown as director compensation. This represents customary disclosure of insider liquidity rather than a governance red flag, given the small stake relative to total shares outstanding.
