Market Downturn: Horizon Space Acquisition II, Astrotech, Momentus, Destiny Tech100, and SATG Face Significant Losses

• A completed SPAC business combination triggered major volatility in Horizon Space Acquisition II Corp.
• Several high-volatility small-cap stocks and space-related names declined sharply during the session.

Today’s market showed significant losses for several companies and funds, including Horizon Space Acquisition II Corp. (NASDAQ: HSPT), Astrotech Corporation (NASDAQ: ASTC), Momentus Inc. (NASDAQ: MNTS), Destiny Tech100 Inc. (NYSE: DXYZ), and the Leverage Shares 2x Long SATS Daily ETF (NASDAQ: SATG). These stocks and funds experienced sharp price drops driven by company-specific events, sector volatility, and leveraged product mechanics.

Horizon Space Acquisition II Corp. led the decline, falling to $5.80. The move came after SL BIO Ltd. and Horizon Space Acquisition II announced the closing of their business combination. After the transaction, SL Bio and Horizon Space became wholly owned subsidiaries of SL Science Holding Limited, which is expected to trade on the Nasdaq Global Market under the ticker symbol SLBT beginning June 15, 2026. 

Astrotech Corporation shares fell to $19.01, despite the company recently announcing that its 1st Detect TRACER 1000 system received ECAC certification for wand swabbing in aviation security operations. Since this was positive operational news, the decline appears more likely tied to volatility and profit-taking after earlier momentum rather than a negative company announcement.

Momentus Inc. dropped 26.69% to $11.95 on heavy trading volume of more than 10 million shares. The company had recently attracted investor attention after strengthening its balance sheet and reporting mission progress, but today’s decline suggests traders were taking profits after a sharp prior move. No clear same-day negative company announcement was confirmed.

Destiny Tech100 Inc (DXYZ). fell to $28.97. DXYZ remains highly volatile because it trades as a closed-end fund offering exposure to private technology companies, including SpaceX, and has previously traded at a significant premium to its reported net asset value.

The Leverage Shares 2x Long SATS Daily ETF fell to $14.11. This ETF is designed to deliver 200% of the daily performance of EchoStar Corporation (NASDAQ: SATS), before fees and expenses. Because EchoStar shares declined sharply, SATG’s 2x long structure magnified the move lower.

In summary, the day’s losses were driven by different factors rather than one single market theme. Horizon Space Acquisition II declined around the closing of its business combination with SL BIO, Astrotech and Momentus experienced high-volatility pullbacks, Destiny Tech100 remained pressured by valuation and private-market exposure concerns, and SATG fell because of weakness in EchoStar shares. Investors should separate confirmed catalysts from speculation when analyzing these sharp market moves.
