Key Events

  • Substantial Open Market Sale

    Mark N. Tompkins, a 10% owner, sold 95,000 shares of Aeluma, Inc. common stock for a total value of $1,534,585 in open market transactions between January 29 and February 2, 2026.

  • Continued Shareholder Reduction Trend

    This sale follows a previous Form 4 on January 23, 2026, which reported another 10% owner selling over $2.0 million in stock, and a Schedule 13D/A on January 2, 2026, detailing a former COO and Director significantly reducing their beneficial ownership.


Analysis

This Form 4 filing indicates a significant open market sale by Mark N. Tompkins, a 10% owner of Aeluma, Inc., disposing of over $1.5 million in common stock. This transaction, representing a notable portion of the company's market capitalization, contributes to a recent pattern of substantial shareholder reductions. It follows a Form 4 filed on January 23, 2026, reporting another 10% owner's sale of over $2.0 million, and a Schedule 13D/A on January 2, 2026, where a former executive significantly cut their stake. Such a series of large insider and major shareholder sales could signal a lack of confidence or a strategic shift in investment by key stakeholders, potentially creating downward pressure on the stock.

At the time of this filing, ALMU was trading at $15.85 on NASDAQ in the Manufacturing sector, with a market capitalization of approximately $283M. The 52-week trading range was $5.69 to $25.88. This filing was assessed with negative market sentiment and an importance score of 7 out of 10.
