Dream Finders Homes entered subscription agreements on September 14, 2026, selling 225,000 shares of Series B Convertible Preferred Stock for $225.0 million, and used the proceeds to redeem its Series A preferred stock.

The preferred stock ranks senior to common stock on dividends and liquidation, carries a 12.00% cumulative dividend, and can convert to Class A common stock at a discount after six years, so it adds a senior claim and potential dilution for common shareholders.

On September 15, 2026, Iridium signed a fourth amendment to its credit agreement, tied to its pending merger with Rocket Lab. The amendment states that the merger will not count as a change of control under the credit agreement, so the term loans can remain outstanding after closing. Certain loan terms become more costly for Iridium only after the merger closes, including higher interest margins, a repricing premium and an exit fee.
The amendment, dated September 15, 2026, is among Iridium, Iridium Satellite LLC, the lenders and Deutsche Bank AG New York Branch as agent.
After closing, term loan rates would be SOFR plus a 2.50% to 3.00% margin, or base rate plus a 1.5% to 2.00% margin, based on Iridium's credit ratings.
After closing, a 1.00% prepayment premium applies to repricing transactions, and a 1.00% exit fee applies to term loans prepaid after the first anniversary of closing.
The merger agreement with Rocket Lab was dated June 28, 2026; the Fourth Amendment's changes take effect only if the merger closes.
