USA Rare Earth (USAR) closes Serra Verde deal; $100 million DFC tranche discharged at closing

What the closing filing actually adds

The lock-up terms had been on the record for six weeks as well. Friday's 8-K points back to the definitive proxy filed on July 24th, where the form of the agreement ran as an annex. So the closing confirmed those restrictions instead of introducing them, and that's most of what a closing 8-K is for. They work in thirds. The filing describes the signers as Serra Verde's shareholders plus certain employees and consultants. For each of them, one third of the stock is held for 90 days, one third for 180, and one third carries no restriction under those agreements at all. The DFC goes unnamed among the signers, so the ladder covers the people who signed it and stops there. The separate track is registration, the paperwork that lets restricted stock be resold to the public, and USA Rare Earth agreed to file its resale statement one business day after closing. That statement is the usual route to market, though restricted shares can also move later under an exemption such as Rule 144.

Then comes the loan, which is the one place the closing moved a number. Merger Sub assumed Serra Verde's finance agreement with the DFC, a facility sized at up to $565 million. That splits into an initial tranche of up to $465 million and an incremental tranche of up to $100 million. The incremental piece had been funded before closing. The DFC held warrants issued alongside it. Those warrants were cancelled just before the merger and converted into merger consideration. Once that consideration and the outstanding fees and interest were paid, the 8-K says the incremental principal was deemed repaid in full. The obligations were deemed satisfied and discharged. So the debt riding into USA Rare Earth is the initial tranche, capped at $465 million, not the headline $565 million. The filing skips a closing-date balance, though it does give a June 30 figure. The pro forma exhibit puts $425.0 million outstanding across both tranches at that date. Subtract the $100 million discharged at closing and the last disclosed initial-loan balance is $325 million, before any later draws or repayments.

On terms, the initial loan carries the secured overnight financing rate plus 4.0 percent with a floor of zero, a term of up to fifteen years, and repayment in up to 49 quarterly sculpted installments. Sculpted is a project finance word: each payment gets sized against projected cash flow, so there's a different figure due most quarters. The collateral is the Brazilian business, all of Merger Sub's shares plus substantially all of its assets.

A new chief executive on October 1st

Two directors joined the board on the day the deal closed. Thras Moraitis, who ran Serra Verde, is now president of USA Rare Earth and has taken a seat. He gets the chief executive job on October 1st, when Barbara Humpton retires from it, and his base salary is set at 905,000 Swiss francs. Sir Mick Davis joins as well. He chaired Serra Verde and used to run Xstrata. A side agreement gives Vision Blue the right to name one more director for as long as it holds at least 5 percent of the stock.

"Today marks a significant milestone for USA Rare Earth, and I am pleased to welcome the Serra Verde team to our platform," Humpton said in the announcement. Moraitis, in the same release, called the combination "the culmination of a 15-year journey to build a scaled, sustainable source of the vital rare earth materials that power the technologies of the future."

What they bought is a mine in Goias, Brazil that started producing in January 2024. It's still being tuned. The company says the first stage should hit a run rate of about 4,000 tons a year of total rare earth oxide by the end of 2026. A second stage is under construction. It targets average production of 6,400 tons, with commissioning expected to begin within twelve months. USA Rare Earth also describes Serra Verde as the only scaled producer outside Asia of all four magnetic rare earths. That's why Washington keeps writing checks around it, the same federal push behind a $400 million scandium loan to Sunrise Energy Metals. A government-backed vehicle capitalized at $1.55 billion agreed in August to buy the first phase of the output for fifteen years, which we covered when the vehicle was finished.

The open question the filing leaves behind is what the unrestricted stock does. Registration makes a sale possible, and the document leaves intent alone. The DFC, for its part, converted warrants into its stake. Any selling turns up in later filings, and those land on USAR's filings page as they arrive.
