Discussion of non-GAAP financial measures

Our non-GAAP financial measures should only be read in conjunction with our consolidated financial statements prepared in accordance with GAAP. We believe these measures help investors understand our core operating results without the effect of often one-time charges and other items outside normal operations. They are not a substitute for financial measures prepared under U.S. GAAP.

Refer to the schedules at the end of this release for additional information, including a reconciliation of our GAAP to non-GAAP measures.

* not meaningful

Our non-GAAP financial measures reflect the following adjustments:

•Stock-based compensation: We have excluded stock-based compensation from our non-GAAP operating expenses and profitability measures. Although stock-based compensation is a key incentive offered to our employees, and we believe such compensation contributed to our revenues recognized during the periods presented and is expected to contribute to our future revenues, we continue to evaluate our business performance, excluding stock-based compensation.

•Capped call transactions: We have excluded gains and losses related to our capped call transactions held at fair value under U.S. GAAP. The capped call transactions are expected to reduce common stock dilution and/or offset any potential cash payments we must make, other than for principal and interest, upon conversion of the Notes. We believe excluding these amounts from our non-GAAP financial measures is useful to investors as the types of events giving rise to them are not representative of our core business operations and ongoing operational performance.

•Legal fees: Includes legal and related fees arising from proceedings outside the ordinary course of business. We believe excluding these amounts from our non-GAAP financial measures is useful to investors as the disputes giving rise to them are not representative of our core business operations and ongoing operational performance.

•Repurchases of convertible senior notes: We have excluded gains from the repurchases of Convertible Senior Notes. We believe excluding these amounts from our non-GAAP financial measures is useful to investors as the types of events giving rise to them are not representative of our core business operations and ongoing operational performance.

•Restructuring: We have excluded restructuring from our non-GAAP financial measures. Restructuring fluctuates in amount and frequency and is significantly affected by the timing and size of our restructuring activities. We believe excluding the impact from our non-GAAP financial measures is useful to investors as these amounts are not representative of our core business operations and ongoing operational performance.

•Interest on convertible senior notes: In February 2020, we issued convertible senior notes, due March 1, 2025, in a private placement. We believe that excluding the amortization of issuance costs provides a useful comparison of our operational performance in different periods.

•Amortization of intangible assets: We have excluded the amortization of intangible assets from our non-GAAP operating expenses and profitability measures. Amortization of intangible assets fluctuates in amount and frequency and is significantly affected by the timing and size of acquisitions. Investors should note that intangible assets contributed to our revenues recognized during the periods presented and are expected to contribute to future revenues. Amortization of intangible assets is likely to recur in future periods. We believe excluding these amounts provides a useful comparison of our operational performance in different periods.

8

•Foreign currency transaction loss (gain): We have excluded foreign currency transaction gains and losses from our non-GAAP profitability measures. Foreign currency transaction gains and losses fluctuate in amount and frequency and are significantly affected by foreign exchange market rates. Foreign currency transaction gains and losses are likely to recur in future periods. We believe excluding these amounts provides a useful comparison of our operational performance in different periods.

•Other: We have excluded gains and losses from our venture investments, capital advisory expenses, and incremental expenses incurred integrating acquisitions. We believe excluding these amounts from our non-GAAP financial measures is useful to investors as the types of events giving rise to them are not representative of our core business operations and ongoing operational performance.

•Diluted weighted-average number of common shares outstanding:

•Stock-based compensation: In periods of non-GAAP income, we've included the dilutive impact of stock-based compensation in our non-GAAP weighted-average shares. In periods of GAAP loss, these shares would have been excluded from our GAAP results as they would be anti-dilutive for GAAP. We believe including the dilutive effect of stock-based compensation in our non-GAAP financial measures in periods of income is helpful to investors as this provides a useful comparison of our operational performance in different periods.

	2023		2022
GAAP	(21)	%	(165)	%
non-GAAP	22	%	22	%

Our GAAP effective income tax rate is subject to significant fluctuations due to several factors, including excess tax benefits generated by our stock-based compensation plans, gains and losses on our capped call transactions, tax credits for stock-based compensation awards to research and development employees, and unfavorable foreign stock-based compensation adjustments. We determine our non-GAAP income tax rate using applicable rates in taxing jurisdictions and assessing certain factors, including historical and forecasted earnings by jurisdiction, discrete items, and ability to realize tax assets. We believe it is beneficial for our management to review our non-GAAP results consistent with our annual plan's effective income tax rate as established at the beginning of each year, given tax rate volatility.

Our non-GAAP free cash flow measures reflect the following adjustments:

We believe excluding these amounts provides a useful comparison of our operational performance in different periods.

•Legal fees: Includes legal and related fees arising from proceedings outside the ordinary course of business. We believe excluding these amounts from our non-GAAP financial measures is useful to investors as the disputes giving rise to them are not representative of our core business operations and ongoing operational performance.

ANNUAL CONTRACT VALUE

(in thousands, except percentages)

Annual contract value (“ACV”) - ACV represents the annualized value of our active contracts as of the measurement date. The contract's total value is divided by its duration in years to calculate ACV. ACV is a performance measure that we believe provides useful information to our management and investors. In 2023, we changed our ACV calculation methodology for maintenance and all contracts less than 12 months to align with other contract types. Previously disclosed ACV amounts have been updated to allow for comparability.
