Insights

Institutional Ownership Analyst

Passive ownership disclosure: 1.33M units, 2.76% stake.

The Schedule 13G/A amendment lists West Texas Minerals LLC, Davidson Kempner Capital Management LP and Anthony A. Yoseloff as reporting persons holding 1,331,868 Common Units. The filing cites February 24, 2026 as the outstanding-share anchor: 48,255,450 units.

The filing structure and the use of Schedule 13G/A language indicate a passive or investment-manager reporting posture rather than an active-control intent. Future SEC filings or Form 13D would be needed to show activist or control plans.

3 terms

Schedule 13G/A regulatory

"This Statement is filed by each of the entities and persons listed below"

A Schedule 13G/A is an amended public filing with the U.S. securities regulator that updates a previous Schedule 13G, disclosing when an individual or group holds a substantial (typically over 5%) stake in a company and is claiming a passive, non‑controlling intent. Investors monitor these updates because rising or falling holdings can signal changing confidence, potential future moves, or shifts in voting power — like watching a public ledger where large shareholders quietly adjust their positions.

Beneficially owned financial

"Amount beneficially owned: The information required by Item 4(a)"

Beneficially owned describes securities or assets where a person has the economic rights and control—such as the right to receive dividends and to direct voting—even if legal title is held in another name. Think of it like having the keys and using a car that’s registered to someone else: you get the benefits and make decisions. Investors care because beneficial ownership reveals who truly controls value and voting power, affecting corporate decisions and takeover dynamics.

Dispositive power financial

"Shared Dispositive Power 1,331,868.00"

Dispositive power is the authority to decide the final outcome of an asset, legal claim, contract, or corporate action — in effect the power to dispose of or resolve something. For investors it matters because whoever holds that authority can determine who gets paid, who controls an asset or vote, and how risks and returns are allocated; think of it like holding the key that lets you lock in the winner or loser in a deal.
