## Questions

### How does JSSI Aviation Capital source its deal flow?

Deal flow originates primarily through the parent company's maintenance-program client network, which covers thousands of business jets globally. JSSI's technical advisors and service-sales teams identify owners and flight departments seeking liquidity, replacement aircraft, or lease restructuring, giving the investment arm a direct origination channel that bypasses broker-intermediated auctions. The firm also sources through long-standing relationships with aircraft manufacturers, completion centers, and corporate flight departments.

### Does JSSI Aviation Capital invest in commercial aviation or only business jets?

The firm's mandate is concentrated on the business-aviation segment — mid- to large-cabin corporate jets and turboprops — rather than commercial-airline equipment. This focus aligns with the parent company's maintenance-program specialism and data advantage. Commercial-aviation assets, which require different technical-underwriting capabilities and capital-reserve modeling, are not part of the disclosed strategy.

### What geographic markets does JSSI Aviation Capital cover?

The firm invests across North America, Europe, and the Middle East, mirroring the footprint of its parent's installed base of maintenance-program clients. The United States represents the largest concentration of assets given the size of the domestic business-aviation fleet, but European and Middle Eastern transactions feature regularly where corporate operators seek financing or lease restructuring.

### Who are the key investment decision-makers at JSSI Aviation Capital?

The firm has not publicly disclosed its investment-committee composition or named a chief investment officer. Senior leadership historically has included executives with backgrounds spanning aviation finance, asset-backed lending, and the parent company's technical-services operations, but specific named principals are not a matter of public record.

### Does JSSI Aviation Capital co-invest with external institutional partners?

Yes. In 2023, the firm acknowledged raising a dedicated aviation-finance vehicle alongside a syndicate of institutional co-investors to expand its lending capacity. The firm also structures club-style transactions where larger aircraft or portfolio acquisitions require capital pooling beyond its own balance sheet.
