Activist stake amendment (position change)
Actionable Insight • Neutral

The sponsor's reduced stake is a mechanical adjustment tied to the over-allotment option expiration, not a strategic exit. Monitor for any initial business combination announcement, as the sponsor still holds a controlling 20.71% stake and the SPAC's clock is ticking.
