NextDC plunges 44% on profit warning; Nvidia in talks to back Firmus after failed IPO

Australian data centre operator NextDC fell 44% after issuing a profit warning, deepening sector-wide investor concerns about AI infrastructure spending. Separately, Nvidia is reportedly in talks to inject capital into Firmus, a data centre firm whose IPO failed, signaling continued consolidation and capital strain in the sector.
