How “Most active RIA acquirers” is calculated

An acquisition is a dated transfer of a registered investment adviser's business to another adviser, read from Form ADV filings (the target's withdrawal and its advisers' registrations moving to the acquirer) and from the firms' announcements.

From 7 October 2024 to 7 October 2026. The window moves with the calendar, and the ranking is recomputed from the records every hour.

• Each acquirer is counted once per acquired firm.
• The date is the deal date where announced, else the date the advisers moved on the registration record.
• Ranked by the number of distinct counted events in the window. A tie is broken by the date of the firm's most recent counted event, then alphabetically.

• Internal restructurings, where a firm re-registers under a related entity.
• Acquisitions with no date, or dated outside the window.

• SEC and state Form ADV filings (IAPD) for both firms
• FINRA BrokerCheck and IAPD registrations of the advisers who moved
• The firms' own announcements
