Activist stake amendment (position change)
Actionable Insight • Neutral

The exchange of preferred for common shares increases Heilbron's common equity stake without cash outlay, but the absence of new activist demands suggests this is a portfolio rebalancing move. Monitor for any future 13D amendments that signal a shift in strategy or escalation of demands.
