Aethlon Medical, Inc. (NASDAQ: AEMD) surged up 383.22% to $6.91 in exceptionally active trading, with roughly 80.0 million shares changing hands versus average daily volume of about 1.1 million. The stock rallied after Aethlon announced a definitive all-stock merger with private biotech North Immunology and an oversubscribed $180 million private placement expected to finance the combined company into the second half of 2028. Following the transaction’s expected closing, legacy Aethlon holders would own about 4.75% of the renamed North Immunology, which is expected to trade under the ticker NRTX.

The rally followed Surf Air’s first commercial contract for its Palantir-powered OperatorOS platform with Sprintbach Aviation; under the revenue-sharing agreement, Surf Air will receive a percentage of revenue from flights run through the software, providing a new potential software-revenue stream beyond its airline operations.
