MARATHON OIL COMPANY LLC

The ownership records associated with this profile list several institutional holders, including SPDR S&P 500 ETF Trust, Fidelity 500 Index Fund, iShares Core S&P 500 ETF and Wellington Management Group, LLP, each shown holding stakes of under 2%. This pattern of small, similarly sized index-fund and asset-manager holdings is characteristic of the public shareholder register of a listed corporation, not of the membership interests in a privately held Texas limited liability company such as Marathon Oil Company LLC.

Texas does not require a limited liability company to publicly disclose its members or their percentage interests, and no independently verified shareholder, membership-interest or beneficial-ownership filing specific to Marathon Oil Company LLC was located. Records available through the Texas Secretary of State for this entity type do not include a public members’ register.

Separately, Marathon Oil Corporation – a similarly named New York Stock Exchange-listed company (ticker: MRO) that is a distinct legal entity from this Texas LLC – ceased to be an independently traded public company after ConocoPhillips completed its acquisition of Marathon Oil Corporation on 22 November 2024. Historical index-fund and institutional shareholder data of the kind shown in this profile would be consistent with that former public company’s shareholder register rather than with a current ownership record for Marathon Oil Company LLC.

Data availability: Not found. No shareholder or ultimate-beneficial-owner information specific to Marathon Oil Company LLC as a Texas limited liability company could be independently verified as of the information date (September 2026).

The source registry lists four individual officers together with a corporate registered agent for Marathon Oil Company LLC, as of the registry’s information date. The listed roles – Vice President, Controller & Chief Accounting Officer; Executive Vice President of Operations; and Executive Vice President, General Counsel & Secretary – correspond to senior leadership titles previously held at Marathon Oil Corporation, a separate, similarly named public company acquired by ConocoPhillips in November 2024.

External, dated sources indicate that at least two of the named individuals had moved to other companies before this LLC’s Texas registration became effective in September 2025. Zach B. Dailey, listed here as Vice President, Controller & Chief Accounting Officer, was appointed Executive Vice President and Chief Financial Officer of Talos Energy Inc., effective 18 August 2025, according to Talos Energy’s own announcement and a related U.S. Securities and Exchange Commission filing. Kimberly O. Warnica, listed here as Executive Vice President, General Counsel & Secretary, was appointed Executive Vice President and Chief Legal Officer of APA Corporation in January 2025 and named that company’s Corporate Secretary in August 2025, according to APA Corporation’s own leadership disclosures.

These external appointments indicate that the officer roster shown in this record may not reflect the current officers of Marathon Oil Company LLC as of the information date, and should be treated with caution pending confirmation from a Texas Secretary of State filing naming this entity’s current officers directly. No reliable, independently verifiable current-status information was located for the remaining named individual, Michael A. Henderson.

The registered agent named for the entity, Corporation Service Company (doing business as CSC Lawyers Incorporating Service Company), is a corporate registered-agent provider rather than a natural person; its Austin, Texas address is a service-of-process and correspondence address only, and is not the residence or workplace of any individual officer.

Nationality is not disclosed for any named individual in the source registry, and Texas company filings of this type do not require nationality or country-of-residence information to be publicly reported.
