## Questions

### Who runs investment decisions at Aethon Energy?

Gordon McCormick, the founder and CEO, maintains direct oversight of the firm's acquisition strategy and portfolio allocation. The firm does not disclose an independent investment committee structure, and McCormick's three-decade tenure makes him the central decision-making figure. Key basin-level operating decisions are delegated to field-based management teams, but material capital allocation decisions flow through the Dallas headquarters.

### How does Aethon source proprietary deal flow?

Aethon sources acquisitions through longstanding relationships with public E&P companies divesting non-core assets, a channel demonstrated by its deals with Anadarko, BP, and Tellurian. The firm's permanent-capital structure allows it to move quickly on negotiated bilateral transactions without the execution risk that private-equity fund timelines introduce. Its deep operational presence in the Haynesville — where it is the largest private producer — gives it basin-level intelligence that competitors without operated positions lack.

### Which sectors does Aethon explicitly avoid?

Aethon has shown no appetite for offshore exploration, international oil and gas assets, or downstream refining and marketing. The firm concentrates exclusively on onshore US producing basins. It has also avoided the public-equity energy space, maintaining a purely private portfolio without disclosed positions in publicly traded E&P companies or energy-sector equities.

### How is Aethon's institutional capital partnership structured?

In 2023 the Canada Pension Plan Investment Board and Dutch pension manager PGGM committed roughly $3 billion to a managed partnership designed to acquire and develop Haynesville natural gas assets, with Aethon serving as the operator. This vehicle sits alongside Aethon's own balance-sheet capital rather than within a commingled fund, giving each institutional partner direct exposure to a defined asset pool under Aethon's operational control.

### What is Aethon's known posture on gas versus oil exposure?

Aethon has tilted its portfolio increasingly toward natural gas-weighted assets, anchored by its dominant Haynesville position, which produces primarily dry gas. The firm retains oil-weighted positions in the Permian and Rockies, but its largest capital commitments since 2016 have targeted gas resources. This gas concentration makes Aethon a significant but under-the-radar participant in US LNG feedgas supply chains.
