SpacDeskConvertible Note
A debt instrument used in SPAC transactions that converts into equity — typically common stock or warrants — at or after the business combination, often issued by the sponsor as a working-capital bridge or by the combined company as post-closing financing.
Convertible notes appear at multiple stages of the SPAC lifecycle, serving different purposes depending on the context. The most common is the sponsor's working-capital loan: a promissory note from the sponsor to the SPAC, funding day-to-day operating expenses during the target search. These notes typically convert into warrants (at $1.00 or $1.50 per warrant) at the sponsor's election upon business combination closing.
In the deal context, convertible notes are sometimes used as part of the transaction financing alongside or instead of a traditional PIPE. A convertible note PIPE offers investors downside protection through the debt component while preserving equity upside through the conversion feature. These structures became more common in 2023–2025 as PIPE investors demanded more favorable terms in a buyer's market.
Post-closing, the combined company may issue convertible notes as a bridge financing mechanism. These are particularly common when the de-SPAC closed with high redemptions and limited cash, and the company needs capital before it can access the public equity markets via a secondary offering. The conversion terms — strike price, maturity, and anti-dilution protections — are critical for modeling the company's fully diluted share count.
Convertible notes add complexity to SPAC dilution analysis. Unlike shares, which have a fixed dilution impact, convertible instruments create conditional dilution that depends on conversion timing, stock price, and the noteholder's election. SpacDesk tracks convertible instruments across the capital structure, flagging their potential dilution impact in the fully diluted share count calculations.
