Going-concern doubt — flagged Aug 6, 2026

Substantial doubt about the company's ability to continue as a going concern.

“Management has determined that we currently lack the liquidity needed to sustain operations for a reasonable period of time, which is considered to be at least one year from the date that the unaudited condensed financial statements and the notes thereto included in the Report under Item 1. "Financial Statements" are issued, as we expect to continue to incur significant costs in pursuit of our acquisition plans. In addition, Management has determined that if we are unable to complete an initial Business Combination within the Completion Window, then we will cease all operations except for the purpose of liquidating. These conditions raise substantial doubt about our ability to continue as a going concern.”

Who Holds DRDBW

Last 6 quarters through Jun 30, 2026

Each kind of 13F filer's share of the common shares 13F filers report. Holder type comes from regulatory records, never the filer's name; style, turnover and horizon are measured from each filer's own 13F book. The quarter selector does not change this card.

Jun 30, 2026: 36 filers, like-for-like change -0.6%; actively managed books -0.6%.

Holder type Share Filers Change
Registered adviser 73.9% 23 -1.6%

How the mix is measured

Shares are 13F common shares restated to today's split basis; options and principal amounts are left out. The change compares only filers with a 13F in both quarters and keeps each filer in its bucket of the later quarter on both sides; a filer that continues under a new CIK is compared through its successor. Holder type comes from each filer's current regulatory profile; client base and private funds come from the Form ADV roster current at each quarter end (rosters from December 2019, so an earlier quarter reads Unknown). Style, turnover, horizon and book size are measured from each filer's 13F book in the newest measured quarter, and Not measured means none was. Actively managed books are those measured systematic-like, concentrated or diversified active.

Conviction and Crowding

36 13F filers, quarter ended Jun 30, 2026

Measured across every 13F filer's common-share book once the quarter's filing window closed. Crowding counts filers with high turnover or that advise private funds on Form ADV.
