CLEANSPARK (CLSK) CFO Gary Vecchiarelli Exercises Options, Sells Shares

What Happened
Gary Anthony Vecchiarelli, President and CFO of CLEANSPARK (CLSK), executed a conversion/exercise of 1,606 derivative securities into 1,606 shares at an exercise price of $0 on 2026-08-13. On 2026-08-14, 632 of those shares were surrendered/withheld at $11.51 per share to cover tax withholding obligations, generating a tax withholding value of $7,274. The Form 4 shows the withholding transaction was made pursuant to a Rule 10b5-1(c) plan.

Key Details

• Transaction dates: conversion/exercise 2026-08-13; tax withholding (disposition) 2026-08-14. Filing date: 2026-08-14 (timely).
• Prices and values: exercise/conversion price $0 for 1,606 shares; 632 shares withheld at $11.51 each = $7,274 withheld.
• Transaction codes: M = exercise/conversion of derivative; F = payment of exercise price or tax liability (withholding).
• Shares owned after transaction: not specified in the excerpt of the filing provided.
• Notable footnotes: the withholding was executed under a Rule 10b5-1(c) trading plan adopted May 13, 2026 (F1). The filing also references multiple outstanding RSU/LTIP/STPA awards with various vesting and performance conditions (F2–F7).

Context

• An exercise/conversion at a $0 price can reflect conversion of vested RSUs or awards with no cash strike; the Form 4 labels it a derivative exercise but does not specify the award type.
• The 632-share action is a tax-withholding event (common after vesting) rather than an open-market sale; the economic impact is modest (~$7.3K).
• Use of a 10b5-1 plan means the withholding/sale was prearranged, which typically reduces the implication of trading timed to nonpublic information.
