Core Scientific, Inc. (CORZ) experienced a significant after-hours plunge of 5.60%, following the release of its first-quarter fiscal 2026 financial results.

The company reported a net loss of $347.2 million for the quarter, a sharp swing from profitability, despite a 44.9% year-over-year revenue increase to $115.2 million. The results included substantial non-cash impairment charges of $266.5 million, which weighed heavily on investor sentiment.

Adding to the negative pressure, regulatory filings revealed that the company's Chief Legal and Administrative Officer, Todd M. DuChene, sold 10,000 shares of common stock just days before the earnings release, which may have contributed to the bearish after-hours reaction.
