## Questions

### How does EIG source proprietary deal flow in the energy sector?

EIG's deal origination relies on a global network of energy operators, project developers, and national oil company relationships cultivated over four decades. The firm's willingness to provide structured solutions — such as preferred equity, mezzanine debt, or pipeline capacity monetizations — gives it access to transactions that traditional equity funds or bank lenders do not pursue. EIG's permanent capital vehicles also enable it to hold assets indefinitely, which differentiates the firm in negotiations with counterparties that want long-term partners rather than short-term financial buyers.

### What investment stages does EIG typically target?

EIG concentrates on brownfield and mid-life energy assets — existing infrastructure, producing oil and gas fields, and operating power plants — rather than greenfield exploration or early-stage technology. The firm targets assets requiring capital for expansion, de-bottlenecking, or recapitalization. This stage preference reflects the cash-flow profile EIG's institutional LPs expect: contracted or production-linked revenues with visible downside protection, not binary exploration outcomes.

### What is EIG's known posture on co-investments alongside external GPs?

EIG frequently structures co-investment opportunities for its limited partners and regularly partners with sovereign wealth funds and other institutional investors on large-scale transactions. The 2021 Aramco pipeline deal, for example, involved Mubadala Investment Company alongside other institutional co-investors in a consortium anchored by EIG. The firm views co-investment structures as a way to scale check sizes on large infrastructure deals while offering LPs concentrated exposure without additional management fees.

### Does EIG participate in fund commitments or only direct deals?

EIG is a principal investor executing direct transactions and structured financings, not a fund-of-funds allocating to third-party managers. The firm underwrites individual energy assets and companies directly, maintaining in-house technical, legal, and operational due-diligence capabilities. EIG does not market itself as a fund-of-funds vehicle or a gatekeeper selecting external energy GPs on behalf of clients.
