NEW YORK, December 31, 2025, 2:48 PM ET — Regular session
- Sidus Space shares rose about 33% in afternoon trading on Nasdaq.
- The move follows the company’s closing of a $16.2 million public share offering.
- Traders are weighing fresh cash proceeds against dilution from newly issued stock.
Shares of Sidus Space, Inc. (SIDU) jumped about 33% to $3.56 by 2:48 p.m. ET on Wednesday. The stock traded between $2.48 and $3.74, with about 112.7 million shares changing hands.
The rally comes two sessions after Sidus said it closed a best-efforts public offering, raising about $16.2 million in gross proceeds by selling 10.8 million shares at $1.50 each. The company said it plans to use the funds for sales and marketing, operating costs, product development, manufacturing expansion, and working capital. 1
That matters for investors because financing terms can drive short-term trading in microcap stocks, especially when new shares are issued at a steep discount to where the stock later trades. New capital can extend runway, but it also increases share count and can pressure prices if holders sell.
A U.S. securities filing dated Dec. 29 outlined fees tied to the deal. Sidus said it agreed to pay ThinkEquity a 7% cash fee, reimburse up to $125,000 in expenses, and issue warrants to buy up to 540,000 shares at $1.875 per share, exercisable immediately with a five-year term. 2
A “registered direct” offering is a sale of newly issued shares to investors using an existing SEC registration, rather than an unregistered private placement. It can speed up fundraising, but it still dilutes existing shareholders.
Wednesday’s surge left Sidus trading well above the $1.50 offering price. The placement-agent warrants are also in the money at current levels, meaning they can add to dilution if exercised.
Moves in small U.S. space and satellite-linked names were mixed. Redwire was down about 4.3%, while Spire Global slipped about 2.5%.
For traders, the next focus is whether the stock can stabilize after a wide intraday range and heavy volume, or whether the financing-driven move fades into the close.
Investors are also watching for follow-on disclosures tied to the offering, including any updates on share issuance and how quickly proceeds translate into manufacturing expansion and product development. Sidus’ investor calendar currently lists no upcoming events. 3
With the cash raise now complete, attention turns back to execution: landing contracts, scaling production, and showing progress toward revenue that can reduce reliance on frequent equity sales.
