FLD updates S-1 prospectus and revises Bitcoin-secured credit deal

Rhea-AI Filing Summary

Fold Holdings, Inc. has an effective registration statement covering up to 9,282,287 shares of common stock and is filing a new prospectus supplement to incorporate its latest Current Report on Form 8-K. The supplement keeps the existing S-1 in place but updates it with recent information.

The amendment raises the loan fee to 8.5 percent per annum and sets loan assets of up to 45,000,000 USD, secured by Bitcoin held in cold storage at qualified custodians under a tri-party control agreement. Collateral thresholds are reduced, with an initial collateral level of 160%, a collateral call level of 135%, a liquidation level of 115%, and a collateral refund level of 190%, with a maturity date of September 30, 2026.

Insights

Capital structure and credit analyst

Fold tightens Bitcoin-backed loan terms, trading higher interest for lower collateral buffers.

The company’s subsidiary, Fold, Inc., has amended its Master Loan Agreement with Two Prime Lending Limited for a Bitcoin‑secured facility of up to 45,000,000 USD. The annual loan fee increases from 6.5% to 8.5%, which raises borrowing costs but may reflect revised market pricing for this type of digital‑asset collateralized lending.

In exchange, collateral requirements are reduced, lowering the initial collateral level to 160%, with collateral call, liquidation, and refund levels at 135%, 115%, and 190%, respectively. These changes mean less Bitcoin needs to be pledged per dollar borrowed, but also narrow the buffer against adverse Bitcoin price moves before a collateral call or liquidation level is reached.

Collateral remains fully segregated in cold storage with qualified custodians under a tri‑party control agreement, while allowing a limited “Permitted Re‑Pledge” for bona fide receivables financings, with access to collateral only after an Event of Default that continues beyond any notice and cure period. The loan is structured as a fixed term facility with a prepayment option, a first utilization date of September 30, 2025 and a maturity date of September 30, 2026, so subsequent disclosures will show how much of the up to 45,000,000 USD capacity is actually drawn.
