Pay Versus Performance

In accordance with Item 402(v) of Regulation S-K, we are providing the following information about the relationships between compensation actually paid to named executive officers and Company performance. In this section, we refer to “compensation actually paid” (“CAP”) and other terms used in the applicable SEC rules. CAP reflects adjusted values to equity awards during the years shown in the table based on year-end stock prices, various accounting assumptions, and projected performance modifiers, but does not reflect actual amounts paid out for those awards. CAP generally fluctuates due to stock price performance and varying levels of projected and actual achievement of performance goals. For a discussion of how our compensation committee assessed “pay-for-performance” and how our executive compensation program is designed to link executive compensation with the achievement of our financial and strategic objectives as well as stockholder value creation, see “Compensation Discussion and Analysis” above.

2022	Gregg Coccari	Sarah Blanchard, Greg Brown, Prasad Gune, and Llibert Argerich
2021	Gregg Coccari	Sarah Blanchard and Velayudhan Venugopal

(2) The compensation actually paid to our PEO reflects the following adjustments required by applicable SEC rules from total compensation reported in the Summary Compensation Table:

			2021		2022
	Summary Compensation Table Total Compensation for PEO	(a)	$	8,119,586	$	827,481
-	Grant Date Fair Value of Stock Awards and Option Awards Granted in Fiscal Year	(b)		7,285,517		—
+	Fair Value at Fiscal Year End of Outstanding and Unvested Stock Awards and Option Awards Granted in Fiscal Year	(c)		5,150,470		—
+	Change in Fair Value of Outstanding and Unvested Stock Awards and Option Awards Granted in Prior Fiscal Years	(d)		16,901,011		(7,352,637)

-	Fair Value as of Prior Fiscal Year End of Stock Awards and Option Awards Granted in Prior Fiscal Years That Failed to Meet Applicable Vesting Conditions During Fiscal Year	(g)		—		—
=	Compensation Actually Paid		$	44,992,372		$                (15,622,773)

For purposes of the adjustments to determine “compensation actually paid”, we computed the fair value of the stock option awards and RSUs in accordance with ASC 718 at the end of the relevant fiscal year, other than fair values of equity awards that vested within 2022 and 2021, which are valued as of the applicable vesting date. The valuation assumptions used in the calculations of such amounts are set forth in the notes to our audited financial statements included in our Annual Report.

(3) The average compensation actually paid to our non-PEO named executive officers reflects the following adjustments required by applicable SEC rules from total compensation reported in the Summary Compensation Table:

			2021		2022
	Average Summary Compensation Table Total Compensation for Non-PEO Named Executive Officers	(a)	$	10,721,755	$	5,232,058
-	Grant Date Fair Value of Stock Awards and Option Awards Granted in Fiscal Year	(b)		10,240,286		4,631,799
+	Fair Value at Fiscal Year End of Outstanding and Unvested Stock Awards and Option Awards Granted in Fiscal Year	(c)		9,304,017		3,761,186
+	Change in Fair Value of Outstanding and Unvested Stock Awards and Option Awards Granted in Prior Fiscal Years	(d)		1,351,197		(1,085,448)
+	Fair Value at Vesting of Stock Awards and Option Awards Granted in Fiscal Year That Vested During Fiscal Year	(e)		—		5,076,319

-	Fair Value as of Prior Fiscal Year End of Stock Awards and Option Awards Granted in Prior Fiscal Years That Failed to Meet Applicable Vesting Conditions During Fiscal Year	(g)		—		3,836,888
=	Average Compensation Actually Paid to Non-PEO NEOs		$	12,875,733	$	3,321,491

For purposes of the adjustments to determine “compensation actually paid”, we computed the fair value of the stock option awards and restricted stock units in accordance with ASC 718 at the end of the relevant fiscal year, other than fair values of equity awards that vested within 2022 and 2021, which are valued as of the applicable vesting date, and the fair value of RSUs granted in 2022 in exchange for the cancellation of stock options in connection with the Exchange Program or Mr. Brown’s option cancellation agreement, which are valued based on the incremental fair value of such RSUs on the applicable grant date. The valuation assumptions used in the calculations of such amounts are set forth in the notes to our audited financial statements included in our Annual Report.

(4) Total shareholder return is calculated by assuming that a $100 investment was made on at the close of trading on the first full day of trading of our common stock (October 29, 2021) and reinvesting all dividends until the last day of each reported fiscal year.

(5) The peer group used is the Nasdaq Computer Index, as used in the performance graph shown in our annual report. Total shareholder return is calculated by assuming that a $100 investment was made at the close of trading on the first full day of trading of our stock (October 29, 2021) and reinvesting all dividends until the last day of each reported fiscal year.

(6) The dollar amounts reported are our net income (loss) reflected in our audited financial statements.

(7) In our assessment, revenue is the most important financial performance measure (other than stock price) that we used in 2022 to link compensation actually paid to performance. The dollar amounts reported show our revenue as reflected in the audited financial statements included in our Annual Report.
