CLSK · Cleanspark, Inc. · Shareholders & Ownership
One customer — 100% of revenue (the nine months ended June 30, 2026)
“The Company has one mining pool operator (Foundry Digital) that represented 100% of revenue for the nine months ended June 30, 2026 and 2025. Revenues from Foundry Digital represented 100% of the Company's total revenues for each of those years, as all bitcoin mining rewards are received through the Foundry mining pool.”
Every disclosed holder of CLSK in one list: 13F institutions, Schedule 13D and 13G filers, insiders (Forms 3, 4 and 5) and registered funds, each from its own latest filing. Holders nest by CIK and SEC reporting links, never by name, and each is summed once.

49 more nested rows are not shown here; Every filing lists them all.
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.
