Why These Defense Stocks Are Declining This Week

6. Sidus Space, Inc. (NASDAQ:SIDU)

Weekly Decline: -21.25%

Sidus Space, Inc. (NASDAQ:SIDU) is engaged in the design, manufacture, launch, and data collection of commercial satellites. It serves aerospace, commercial space, and defense industries. The company’s share price has plummeted 61% in 2025, and was down by 21.25% last week.

Weak financial position is one of the major drivers of the stock’s poor performance. Sidus Space, Inc. (NASDAQ:SIDU) reported a net loss of $14.3 million for fiscal 2023, which was up from $12.8 million in the prior year. The company has continued to make losses during the first three quarters of fiscal 2024.

While a 90% year-over-year increase in revenue in Q3 2024 did raise a glimmer of hope for recovery, investors remain concerned about the company’s weak gross profit margins, which stood at just 2% during the third quarter – the most recent declared results.
