Insights

Securities Attorney

Form 144 notices list proposed affiliate sales and multiple grant lots.

These notices are administrative filings that report intended sales of Common Stock by affiliates and identify broker details and grant-origin share lots. The excerpt lists numerical entries (for example, 103,927 and 124,249,941) and a filing date of 05/11/2026.

Because Form 144 is a notice of proposed sale, actual sale execution, pricing, and proceeds are not confirmed here; subsequent SEC or broker reporting would show completed transactions.

FAQ

AI-generated questions and answers. How Rhea-AI works. Not financial advice.

What does Matador Resources' Form 144 filing mean (MTDR)?

It reports proposed sales of Common Stock by affiliates or insiders. The filing lists multiple grant-origin lots and broker details, including numeric entries such as 103,927 and a date of 05/11/2026, but does not itself confirm completed sales.

Does the Form 144 show how many shares Matador Resources sold?

No, it notifies planned sales rather than completed transactions. The excerpt lists share‑lot numbers (for example, 103,927 and 124,249,941) and broker information; actual sale quantities and proceeds would appear in subsequent trade reports.

Who is identified as the broker or recipient in the filing?

The excerpt includes a broker reference to Edward Jones with an address and NYSE notation. The filing text lists broker details alongside the grant-origin share entries and the 05/11/2026 anchor.

Are the listed grant entries in Form 144 immediately transferable?

The filing lists grant-origin lots (dates and share counts) but does not state transferability. The entries show grant dates and quantities; any transferability or sale execution depends on the affiliate's actions and applicable resale rules.
