Insights

Financial Analyst

TL;DR: Routine Schedule 13G discloses an 8.09% passive stake with sole voting and dispositive power; material as a sizable minority holding.

The filing reports a meaningful minority position of 8,408,391 shares (8.09%) in ProPetro (PUMP). Sourcerock asserts passive intent by using Schedule 13G and certifying the shares were acquired in the ordinary course, which typically signals no plan to seek control. However, sole voting and dispositive power over the shares means Sourcerock can determine votes and transactions for this block, giving it practical influence over shareholder outcomes despite the passive intent. This is a material ownership disclosure that investors and governance analysts should note.

Compliance / Risk Analyst

TL;DR: Filing appears procedurally complete and includes certification and POA; classification as an investment adviser aligns with Schedule 13G usage.

The Schedule 13G includes required elements: issuer identification, CUSIP, reporting person details, exact share counts, percentage of class (8.09%), and a signed certification dated 08/15/2025. A power of attorney is referenced as Exhibit 24 authorizing the signatory. Classification as type "IA" (investment adviser) and filing on Schedule 13G indicates the filer claims passive investment intent, reducing immediate regulatory concern about control transactions. From a compliance perspective, the document contains the standard attestations and disclosures expected for this filing type.
