There's a section of his pay package that says:

  The Performance Hurdles will be adjusted by the Committee equitably and proportionately as determined by the Committee in a manner designed to preserve the economic opportunity provided under the Award, (a) higher to account for acquisition activity for which stock is provided as consideration; and (b) lower to account for a split-up, spin-off, dividend or other distribution (whether in the form of cash, shares, other securities, or other property) or divestiture activity, in each case, that could be considered material to the achievement of the Performance Hurdles, as applicable.

Matt Levine's recent opinion piece for Bloomberg ("GameStop Doesn’t Have Enough Stock", https://archive.ph/3h8wf) goes into a bit more detail about it, including why such an acquisition might still help him get there even if it doesn't instantly get him halfway.
