Ever hear of Sidus Space (SIDU) ?
Chances are that most readers have not, despite the fact that the shares have been publicly traded since late 2021. And no sell-side analysts that I know of cover the firm. The Merritt Island, Florida (Cape Canaveral) based firm is a space industry solution provider. The firm offers services such as satellite design, payload hosting, mission management and AI-enhanced sensor Data-as-a-Service software.
The firm's flight modular satellite, the LizzieSat, is a 3D-printed, multi-sensor, multi-use, multi-mission capable spacecraft that is customizable and built to adapt to changing technology. The firm's 3D printing capabilities include functional prototype and production parts. The firm serves and plans to serve government, defense, intelligence and commercial clientele globally. Recently, Sidus Space announced a partnership with Simera Sense for AI-enhanced imaging to be integrated into the upcoming LizzieSat-4 mission.
Financial Results
Sidus released the firm's results for the fiscal year completed December 31, 2025, on Wednesday morning.
For the full year, Sidus generated revenue of $3.384 million (-27.6%), while the cost of that revenue ran up to $9.076 million (+47.8%). Operating expenses grew 56.6% to $22.316 million. After accounting for non-operating expenses, the firm's net income/loss printed at -$29.474 million, down from -$17.524 million in the year prior. Kind of awful.
Why Show Interest?
Sidus has secured a spot in the U.S. Missile Defense Agency's $151 billion SHIELD program. That's the Scalable Homeland Innovative Enterprise Layered Defense program. The firm was only included in this program as of December 22, 2025, so nine days ahead of the close of the reporting period covered above. This program opens the door for this firm to be taken seriously as a defense contractor, which could obviously be a positive revenue generator moving forward.
In addition, the firm has been selected as a subcontractor on the NASA-funded design study covering space-based radar payloads that would ultimately track orbital debris and space domain awareness as the area above us gets more and more crowded.
Balance Sheet
Sidus ended the year with a cash position of $43.176 million and current assets of $50.689 million. Current liabilities add up to $15.021 million including an asset-based loan of $8.212 million. This puts the firm's current ratio at a quite robust 3.37.
Total assets amount to $66.091 million, which includes only a very small portion labeled as "intangible." Total liabilities less equity comes to $15.455 million. The firm has no longer term debt on the books. This is a very strong balance sheet and what debt there is could be paid off more than five times over out of cash.
Conclusion
This would be a very speculative play, but there is positive momentum in the execution of the business, and the balance sheet is in better than good shape.
Management has raised cash in the past through dilution and that is likely to happen again. The $10,000 Portfolio is willing to take a small stake in this name and let it sit for a while to see if new revenue does blossom off of that late 2025 deal.
Tuesday's Trades
On Tuesday, I wrote of my intention to
-Sell one April 24 $9.50 (ONDS) call for a rough $0.50
-Offer one May 8 $8.00 (OCUL) call at $1.00 (or better). The spread is wide and the series is illiquid, so this may not get done.
Obviously, the market went into uber-rally mode shortly after this was published. What I did was:
-Sold one April 24 $10.50 ONDS call for $0.60
-Offered one May 8 $9.00 OCUL call at $1.25. This offer expired.
Wednesday's Intention
Buy 100 shares of SIDU at or close to the last sale of $2.25.

Please note that due to factors including low market capitalization and/or insufficient public float, we consider SIDU to be small-cap stock. You should be aware that such stocks are subject to more risk than stocks of larger companies, including greater volatility, lower liquidity and less publicly available information, and that postings such as this one can have an effect on their stock prices.
