AI Summary
The Horizon Space SPAC merges with SL Bio to form SL Science and list on Nasdaq as SLBT on June 15, 2026. SL Bio carries an implied equity value of about $5.57 billion with a $7.8 million PIPE to fund gamma delta T cell programs for solid tumors, emphasizing standardization and scalable manufacturing. The governance expansion should support rapid clinical and commercial growth.
Sentiment Rationale
