Insights

TL;DR: Significant insider sales of 2.7M shares at ~$10.50–$12.65 reduce aggregate insider stake but large beneficial ownership remains.

The Form 4 shows material open-market dispositions totaling 2,700,000 common shares executed in multiple tranches at weighted-average prices between $10.8022 and $12.3711. After these sales, the reporting persons continue to hold large indirect positions (around 79.4M–81.2M shares), indicating the transactions were partial reductions rather than full exits. The filing clearly maps the chain of ownership among Bitfury entities and Mr. Vavilovs and includes the required weighted-average pricing disclosures and offers to provide per-trade detail on request.

TL;DR: Transactions are transparently disclosed with ownership chain explained; beneficial ownership disclaimers are included.

The filing provides compliant disclosure of multiple sales by related reporting persons and includes explanatory footnotes detailing record holders and ownership relationships. Each entity disclaims beneficial ownership beyond pecuniary interest, consistent with typical Section 16 reporting. The completeness of footnotes and the offer to provide detailed per-price trade breakdowns support regulatory transparency.
