BKHA · Black Hawk Acquisition Corp · Shareholders & Ownership
Substantial doubt about the company's ability to continue as a going concern.
“The Company has incurred and expects to continue to incur significant professional costs to remain as a publicly traded company and to incur significant transaction costs in pursuit of the consummation of a Business Combination. In connection with the Company's assessment of going concern considerations in accordance with Financial Accounting Standard Board's Accounting Standards Update ("ASU") 2014-15, "Disclosures of Uncertainties about an Entity's Ability to Continue as a Going Concern," management has determined that these conditions raise substantial doubt about the Company's ability to continue as a going concern. In addition, if the Company is unable to complete a Business Combination within the Combination Period, the Company's board of directors would proceed to commence voluntary liquidation and thereby a formal dissolution of the Company. There is no assurance that the Company's plans to consummate a Business Combination will be successful within the Combination Period. As a result, management has determined that such an additional condition also raises substantial doubt about the Company's ability to continue as a going concern. The unaudited consolidated financial statements do not include any adjustments that might result from the outcome of this uncertainty.”View the 10-Q filed Oct 6, 2026

13D/G-only counts each filer's latest 13D or 13G that no 13F report of the listing contains, that names no 13F filer and that no counted insider files. Funds are never summed: their shares sit inside their advisers' 13F reports.

Shares are restated onto today's split basis. Change compares each row with the same holder's previous filing in the same source; a dash means there is none to compare. Nested 13D/G, insider and fund rows are not summed, since a 13F report already holds them.
