Undated item: SpaceX bond sale to replace bridge financing
People familiar with the matter said the partner bank group working with SpaceX (SPCX.O) may begin investor calls as early as next week to discuss a bond offering after the company completes a record IPO. The sources said the bond sale is expected to total at least $20 billion, with investor outreach starting as early as Monday. The plan and timing remain subject to change.
SpaceX plans to issue investment-grade dollar bonds for the first time, with proceeds used to replace a $20 billion bridge loan due in September 2027. IPO filing documents submitted by SpaceX to the US Securities and Exchange Commission show that, as of March 31, the bridge loan accounted for the bulk of the company’s $29.1 billion in long-term debt. The sources said Bank of America, Citi, JPMorgan Chase, Goldman Sachs and Morgan Stanley jointly provided the bridge loan and will lead the underwriting of the planned bond issuance.
