Rithm Acquisition Corp-A

MicroAlgo Inc. shares surged 20.88% in pre-market trading after announcing a novel algorithm for automating quantum circuit design, but the company has not yet disclosed customers, pricing, or a launch timeline.

Rithm Capital shares dropped to a 52-week low of $8.77, declining 3.3% amid heavy trading volume. The selloff reflects broader pressure on mortgage REITs as interest rates climb.
