Four distinct revenue streams flowed through STC:
September 2015 (EFTA00310331): A Letter Agreement between STC and Edmond de Rothschild Holdings establishes a contingency fee: STC would receive $25 million if the EDRH U.S. Department of Justice settlement was $75 million or less. The engagement is described as "risk analysis and estate planning" using "algorithms."
The fee framing is notable: STC — described in its own EDC certificate as a biomedical informatics and DNA database company — was contracted to provide "risk analysis" using "algorithms" for a Rothschild entity facing a DOJ enforcement action. The full Rothschild relationship is documented in GOY-11: The Rothschild Financial Network.
In April 2017, STC issued three invoices to Leon Black, then chairman of Apollo Global Management:
| EFTA | Amount | Description |
|---|---|---|
| EFTA00787656 | $10,000,000 | "financial strategy and planning services" |
| EFTA00587065 | $8,000,000 | "financial strategy and planning" |
| EFTA00585170 | $11,000,000 | "financial strategy and planning" |
These three invoices total $29 million in a single month. Public reporting and court filings established that Black paid Epstein approximately $140 million over the course of their relationship — routed through STC. The invoices describe the same generic "financial strategy and planning" language across all three, despite representing different amounts.
STC was the vehicle through which Epstein invested in:
EFTA01362870 provides the most complete revenue snapshot:
| Revenue Category | H1 2017 Amount |
|---|---|
| Fee income | $8,000,000 |
| Dividends and interest | $1,300,000 |
| Long-term capital gains | $4,700,000 |
| Equity income from SFL | $1,600,000 |
| Income from Haze Trust | $521,000 |
| Total revenue | $15,996,835 |
| Net income | $14,026,237 |
| Margin | 87.7% |
An 87.7% net margin on $16M in H1 revenue indicates minimal operating expenses — consistent with a shell entity performing "no real services" while routing fees from external sources.
WHAT THIS SHOWS AND DOES NOT SHOW: The revenue streams establish that STC received $165M+ from identifiable sources (Rothschild, Leon Black, investment returns). The 87.7% net margin suggests minimal actual service delivery. This does NOT establish that STC's consulting services were fictitious — the Rothschild settlement outcome may have justified the contingency fee, and Leon Black has stated he received financial advice. The characterization of STC as performing "no real services" comes from the USVI Superior Court, not from this analysis.
