Taecker, Chief Engineering and Operations Officer of Aqua Metals, had 1,006 shares withheld on February 24, 2026 to satisfy tax withholding related to the vesting of a previously reported restricted share grant. The withheld shares were valued at $4.76 each for a total of $4,789. This was a tax-withholding disposition (not an open-market sale).

• Withheld shares: 1,006 at $4.76 per share; total value $4,789.

Context

• Tax-withholding share dispositions are routine when restricted stock or RSUs vest and should not be interpreted as a directional buy or sell signal. The filing shows the withholding covered the tax liability on vested awards; a sizable portion of equity remains in unvested RSUs per the footnote.
