Why It Matters
AUM is a key metric for asset managers because it directly affects management fees, potential performance fees and therefore revenue and earnings. Reporting preliminary AUM gives investors an early view of investor flows and portfolio valuation trends for the quarter ended March 31, 2026, but this filing does not provide audited financial results or specific revenue/earnings guidance. Investors should review the attached press release (Exhibit 99.1) and await any further disclosures or quarterly financial statements for detailed impact on revenue and quarterly results.
