STOCKHOLDERS' EQUITY AND COMPENSATION ARRANGEMENTS

Groupon, Inc. Incentive Plan

In August 2011, we established the Groupon, Inc. 2011 Incentive Plan, as amended and restated (the "2011 Plan"), under which options, RSUs and performance stock units for up to 11,875,000 shares of common stock are authorized for future issuance to employees, consultants and directors. The 2011 Plan is administered by the Compensation Committee of the Board. As of September 30, 2022, 3,203,455 shares of common stock were available for future issuance under the 2011 Plan.

Restricted Stock Units

The restricted stock units granted under the Groupon, Inc. Stock Plans (the "Plans") generally have vesting periods between one and four years and are amortized on a straight-line basis over their requisite service period.

The table below summarizes restricted stock unit activity under the Plans for the nine months ended September 30, 2022:


	Restricted Stock Units	Weighted-Average Grant Date Fair Value (per unit)
Unvested at December 31, 2021	2,205,235	$	31.06
Granted	2,233,380	19.14
Vested	(915,272)	33.25
Forfeited	(514,350)	26.94
Unvested at September 30, 2022	3,008,993	$	22.20

As of September 30, 2022, $52.2 million of unrecognized compensation costs related to unvested restricted stock units, excluding any impact of forfeitures, are expected to be recognized over a remaining weighted-average period of 1.19 years.

Performance Share Units

We have previously granted performance share units under the Plans that vest in shares of our common stock upon the achievement of financial and operational targets specified in the respective award agreement ("Performance Share Units"). We have also granted performance share units subject to a market condition ("Market-based Performance Share Units"). Our existing Performance Share Units and Market-based Performance Share Units are subject to continued employment through the performance period dictated by the award and certification by the Compensation Committee of the Board that the specified performance conditions have been achieved.

During the nine months ended September 30, 2022, 20,494 shares of our common stock were issued upon vesting of Performance Share Units granted in 2020 and prior based on the Board's certification of our financial and operational metrics for the year ended December 31, 2020. The weighted average grant date fair value of those shares was $31.97 per share. As of September 30, 2022, we have recognized substantially all expense related to the 17,269 unvested Performance Share Units and the 33,333 unvested Market-based Performance Share Units
