NEW YORK, December 31, 2025, 19:07 ET — After-hours
- Sidus Space (SIDU) jumped about 32% in regular trading before slipping in after-hours.
- The company this week closed a $16.2 million stock offering priced at $1.50 a share.
- A new Schedule 13G filing disclosed a 7.4% stake held by CVI Investments and Heights Capital.
Sidus Space Inc shares surged in year-end trading on Wednesday, closing up 31.9% at $3.52 and then sliding about 10.8% in after-hours to $3.14. The Nasdaq-listed stock ranged from $2.48 to $4.20 on the day as volume ran above 168 million shares. 1
The sharp move matters because Sidus, like many early-stage space hardware and data companies, relies heavily on access to capital markets. When financing news hits, the stock can swing quickly as investors recalibrate near-term cash runway versus dilution.
It also comes at a moment when traders are paying close attention to how much new stock is coming to market. A large share sale can pressure prices by increasing supply, even as it shores up liquidity.
Sidus said on Monday it closed a best-efforts offering of 10.8 million Class A shares at $1.50 per share, for gross proceeds of about $16.2 million. The company said it plans to use the net proceeds for sales and marketing, operating costs, product development, manufacturing expansion and working capital, and said ThinkEquity acted as sole placement agent. 2
A regulatory filing showed the deal was structured as a registered direct offering — shares sold directly to investors under an SEC registration, rather than a traditional underwritten bookbuild. The filing said ThinkEquity’s cash fee was 7% of the purchase price and that the placement agent would receive warrants — a right to buy shares later — for up to 540,000 shares at $1.875 each, exercisable immediately and running for five years. 3
A separate disclosure added to the tape on Wednesday. A Schedule 13G filing — a form used by investors to report significant stakes in public companies — showed CVI Investments, Inc. and Heights Capital Management, Inc. reported beneficial ownership of 4 million shares, or 7.4% of Sidus’ Class A stock. 4
Together, the offering and warrant package highlight a key issue for traders in thinly capitalized names: fresh funding can extend operating runway, but it also brings new potential share issuance that can weigh on prices once stock and warrants are sold or exercised.
The stock’s rally has also been supported by defense-related headlines earlier in December. Sidus said on Dec. 22 it was among awardees under the Missile Defense Agency’s SHIELD indefinite-delivery/indefinite-quantity contract — a government framework that sets a spending ceiling but awards work through later task orders — with a total ceiling of $151 billion. “This milestone reflects our ability to deliver integrated solutions across multiple domains,” founder and CEO Carol Craig said at the time. 5
Other space-linked names were weaker in late trade on Wednesday, pointing to a move driven more by company-specific catalysts than a broad sector bid. Planet Labs was down about 0.1%, BlackSky fell roughly 3%, and Virgin Galactic slipped nearly 3%.
Investors will now watch whether Sidus can sustain elevated prices as the market digests the new supply tied to the offering and placement-agent warrants. They will also look for clarity on revenue timing tied to any SHIELD task orders and follow-on announcements that could confirm demand for its manufacturing and defense offerings.
The company has not listed any upcoming events on its investor relations calendar, leaving the next earnings date and near-term update cadence unclear. 6
