NEW YORK, Jan 2, 2026, 15:50 ET — Regular session
- SIDU was up about 34% at $4.20, trading near the session high on heavy volume.
- A new Schedule 13G showed CVI Investments and Heights Capital Management reporting a 7.4% stake.
- Traders are weighing fresh ownership disclosures against dilution risk after a late-December share sale.
Shares of Sidus Space Inc (SIDU) jumped about 34% on Friday, putting the Nasdaq Capital Market-listed stock at $4.20 in afternoon trade. The session range ran from $3.39 to $4.44 with volume above 132 million shares, market data showed.
The move comes as traders scan a newly filed Schedule 13G — an SEC form used to disclose large passive stakes — showing a 7.4% position in the space and defense technology company.
Why it matters now: the ownership update follows a late-December equity financing that increased share supply. In small-cap names, fresh disclosures and new issuance can magnify day-to-day swings.
A filing dated Dec. 31 showed CVI Investments Inc. and Heights Capital Management Inc. reported beneficial ownership of 4 million Sidus shares, or 7.4% of the class. The form listed Dec. 22 as the event date triggering the disclosure and said Heights is the investment manager to CVI. Sidus Space, Inc.
Schedule 13G is typically used by investors who say they are not seeking to influence or change control of the issuer; it differs from Schedule 13D, which is associated with activist intentions.
In a Dec. 26 Form 8-K, Sidus said it agreed to sell 10.8 million shares at $1.50 each in a registered direct offering, for gross proceeds of about $16.2 million. The company said the deal closed on Dec. 29 and that it planned to use proceeds for sales and marketing, operational costs, product development, manufacturing expansion and working capital. Sidus also said it would issue ThinkEquity warrants to buy up to 540,000 shares at $1.875 per share, exercisable immediately for five years. Sidus Space, Inc.
Registered direct offerings use an effective SEC registration statement so the issued shares are registered for resale, unlike private placements. In a best-efforts deal, the agent markets the shares but does not guarantee a set amount will be sold.
For traders, the financing matters because new shares and warrants can add to dilution — the reduction in existing holders’ ownership percentage when more shares are issued.
Sidus has also pointed to defense work as a growth lever. In December it said it was one of the awardees under the Missile Defense Agency’s SHIELD indefinite-delivery/indefinite-quantity contract vehicle, which the company said carries a $151 billion ceiling; CEO Carol Craig said, “This milestone reflects our ability to deliver integrated solutions across multiple domains.” Sidus Space, Inc.
An IDIQ contract sets broad terms and a maximum value but does not guarantee revenue; task orders are competed and awarded over time. Investors will watch for any task-order wins or backlog updates tied to that program.
Sidus has no upcoming events listed on its investor calendar, leaving traders focused on additional SEC filings and any further capital-raising moves. Sidus Space, Inc.
In the near term, traders are watching whether SIDU can hold above $4 and whether it revisits the $3.14 prior close as support. The session high near $4.44 is another level in focus going into the close.
