NEW YORK, January 1, 2026, 17:27 ET — Market closed
- Sidus Space shares climbed about 17% in the last session on unusually heavy volume.
- Late-December filings detailed a $16.2 million registered share sale priced at $1.50.
- A new SEC ownership disclosure showed CVI Investments and Heights Capital Management holding 7.4%.
Sidus Space shares closed up about 17% at $3.14 on Wednesday, after swinging between roughly $2.50 and $4.20 on about 170 million shares traded. U.S. markets are closed on Thursday for the New Year holiday.
The move matters because the microcap space-and-defense contractor has leaned on equity raises for funding. Fresh capital can buy time, but it also increases the share count and can pressure returns for existing holders.
A Schedule 13G — a disclosure investors file when they own more than 5% of a company — showed CVI Investments and Heights Capital Management held 4 million Sidus shares, or 7.4% of the class. Heights said it acts as investment manager to CVI, according to the filing. Sidusspace
The company agreed to sell 10.8 million shares in a registered direct offering — a share sale registered with the SEC and placed directly with a small group of investors — at $1.50 apiece, for about $16.2 million in gross proceeds, an 8-K filing dated Dec. 26 showed. ThinkEquity served as placement agent and received warrants — the right to buy shares later at a fixed price — to purchase up to 540,000 shares at $1.875 each, the filing said. Sidusspace
Sidus said the offering, which it closed on Dec. 29, will fund sales and marketing, operations, product development, manufacturing expansion and working capital. Sidusspace
That financing backdrop is one reason traders have fixated on the stock. In thinly traded names, added supply from new shares can quickly change the balance between buyers and sellers.
Investors have also tracked the company’s defense push. In December, Sidus said it was among awardees under the Missile Defense Agency’s SHIELD IDIQ contract vehicle — a framework contract that lets an agency issue task orders over time — which it said carries a $151 billion ceiling. “This milestone reflects our ability to deliver integrated solutions across multiple domains,” founder and CEO Carol Craig said.

The stock’s year-end surge adds to a pattern of sharp moves around capital raises and contract headlines. That volatility can persist even when there is no fresh fundamental update, as liquidity thins and speculative positioning shifts.
Before the next session on Friday, traders will watch for follow-through after the holiday break and any additional SEC paperwork tied to recent financings. Ownership updates can also move fast in small floats when new holders cross disclosure thresholds.
Technically, Wednesday’s high near $4.20 and the intraday low around $2.50 are near-term markers, with $3 a round-number level investors often watch. The $1.50 offering price and the $1.875 warrant strike are other reference points for traders gauging potential supply.
Sidus has not listed any upcoming events on its investor-relations calendar, leaving the next earnings date and contract updates as the main items on watch. For now, trading focus is on whether volume cools back toward normal levels after the year-end spike. Sidusspace
