Actionable Insight • Neutral

Monitor for further filings regarding the proposed redomicile to the U.S. and any board or management changes. Oldridge's insider status and stated intent to work with management suggest a collaborative rather than confrontational approach, but the potential for governance shifts could introduce near-term volatility.
