Aeluma CEO terminates planned stock sale arrangement

Aeluma, Inc. (NASDAQ: ALMU) disclosed on October 21, 2026, that its President and Chief Executive Officer, Jonathan Klamkin, terminated a pre-established trading plan. The company filed a Form 8-K with the U.S. Securities and Exchange Commission to report the event, which occurred after the plan had been in effect for more than five months.

The terminated arrangement was adopted on May 23, 2026, under Rule 10b5-1 of the Securities Exchange Act of 1934. This type of plan allows executives to schedule stock sales in advance, providing a defense against allegations of insider trading if the trades occur while the executive is aware of material nonpublic information. The specific arrangement permitted Klamkin to sell up to 300,000 shares of Aeluma common stock.

Aeluma is headquartered at 27 Castilian Drive in Goleta, California. The company is incorporated in Delaware and operates as an emerging growth company. Its common stock, which carries a par value of $0.0001 per share, trades on The Nasdaq Stock Market LLC under the ticker symbol ALMU. The Form 8-K was signed by Christopher Stewart, the company's Chief Financial Officer, and dated October 22, 2026.

The termination of the trading plan means that Klamkin will not proceed with any further sales of Aeluma shares under that specific pre-arranged schedule. The filing notes that the plan was previously reported in the company's Annual Report on Form 10-K for the fiscal year ended June 30, 2026. No other changes to executive compensation or ownership structures were mentioned in the current report.
