Not financial advice. --- # Bitmine Reports $5.4B Unrealized ETH Loss and Ongoing Internal Control Flaws The ether treasury firm's fiscal 2026 Form 10-K revealed a $6.31 billion net loss, persistent control weaknesses, and a new 10-year staking agreement. ## At a glance - **What happened:** Bitmine Immersion Technologies filed its Form 10-K reporting ineffective internal controls, an unrealized $5.4 billion ETH loss, and a $6.31 billion net loss for fiscal 2026. - **Why it matters:** The persistence of internal control deficiencies for a second year underscores accounting risks at the largest institutional ether treasury holder. - **Who is affected:** Bitmine Immersion Technologies shareholders, KPMG, and staking partner American Validator LLC. - **What's next:** Bitmine will file a transition report covering the stub period from Sept. 1 to Dec. 31, 2026, as it aligns its fiscal year to the calendar year. - **Primary source:** [Bitmine Says Its Controls Are Still Not Effective as ETH Ended the Year $5.4 Billion Below Cost](https://unchainedcrypto.com/bitmine-says-its-controls-are-still-not-effective-as-eth-ended-the-year-5-4-billion-below-cost/) — unchainedcrypto.com ## Key points - Bitmine held 5,901,837 ETH valued at $14.56 billion against a $19.95 billion cost basis as of Aug. 31, 2026. - Internal controls over financial reporting remained ineffective for the second consecutive year despite hiring KPMG and overhauling systems. - The firm booked a $6.31 billion net loss for fiscal 2026 and agreed to a 10-year, 1.5% staking fee deal with American Validator LLC. ## Editorial remark - **Context:** Bitmine aggressively scaled its ether balance sheet over the past two years, aiming to accumulate up to 5% of circulating supply. However, rapid growth outpaced the company's internal accounting infrastructure, triggering ongoing governance scrutiny under SEC reporting requirements. - **Impact:** Shareholders face significant accounting oversight risks alongside a $6.31 billion annual net deficit driven by token impairments, even as validation revenue grew to $124.8 million. - **Watch:** The filing of Bitmine's transition report covering Sept. 1 through Dec. 31, 2026, which will show whether KPMG validates remedial accounting controls. Bitmine Immersion Technologies disclosed in its annual Form 10-K filing that its internal financial reporting controls remained ineffective for a second consecutive year as its digital asset portfolio finished fiscal 2026 sharply below cost [1]. The SEC filing, submitted on Nov. 10, covers the 12 months ending Aug. 31, 2026 [1]. The ether treasury firm chaired by Tom Lee held 5,901,837 $ETH at the close of its fiscal year, carrying a fair value of $14.56 billion against a cost basis of $19.95 billion—an unrealized markdown of roughly $5.4 billion [1]. Driven primarily by these markdowns, Bitmine posted an annual net loss of $6.31 billion, compared to net income of $348.6 million in the prior fiscal year [1]. The company also booked a $143.7 million net loss on $ETH-referenced derivative positions, with no contracts open at year-end [1]. Meanwhile, annual revenue increased to $124.8 million from $6.1 million, with staking and validation activities accounting for approximately 97% of the total [1]. At the time of writing, ETH traded at $2,059. ## Governance and Staking Revisions Management previously recognized material weaknesses spanning all five components of the COSO internal-control framework as of Aug. 31, 2025 [1]. Despite implementing an enterprise resource planning system, hiring external consultants, adding accounting staff, and hiring KPMG to replace auditor Bush & Associates in April, Bitmine concluded that the deficiencies persisted because newly deployed controls lacked sufficient operating history [1]. Operational structures also shifted following the fiscal year-end [1]. Bitmine terminated its management services agreement with Ethereum Tower LLC on Sept. 3 without incurring a breakup fee [1]. The following day, Bitmine's staking unit, MAVAN, entered a 10-year advisory contract with affiliate American Validator LLC, agreeing to pay 1.5% of staking rewards generated from the company's staked assets [1]. A subsequent update on Nov. 9 showed holdings expanding to 6,070,092 $ETH, representing 4.97% of the circulating supply as the company approaches its stated 5% threshold, following earlier acquisitions tracked by [Basis Desk](https://basisdesk.news/news/bitmine-buys-20m-eth-nears-five-percent-supply) [1]. The firm is shifting its fiscal year-end to Dec. 31 and plans to file a transition report spanning Sept. 1 through Dec. 31, 2026 [1]. ## Sources 1.
