• • International exposure: ~30% of net revenues from non-U.S. subsidiaries; U.S.-China tensions flagged as specific regional threat to Hong Kong operations
• • Operational vulnerability: no fully redundant systems; no business interruption insurance; hybrid work model increases cyber incident exposure
• • Key-person dependency: Thomas Peterffy controls ~73.7% combined voting power; Compensation Committee he chairs sets his own pay
• • Structural risk: potential $44.6B tax basis step-up liability requiring 85% of realized tax savings paid to Holdings under Tax Receivable Agreement
