(1) Synopsys manages the business on a long-term, annual basis, and considers quarterly fluctuations of revenue and profitability as
normal elements of our business. Amounts may not foot due to rounding.

(2) These segments results are consistent with the information required by ASC 280, Segment Reporting. Synopsys' chief operating decision
maker (CODM) is our Chief Executive Officer (CEO). The CODM does not allocate certain operating expenses managed at a consolidated level
to our reportable segments and, as a result, the reported operating income and operating margin do not include these unallocated expenses as
shown in the table above. Amounts may not foot due to rounding.

(3) Synopsys' fourth quarter of fiscal year 2022 and 2021 ended on October 29, 2022 and October 30, 2021, respectively. For presentation
purposes, we refer to the closest calendar month end.

(4) This excludes the gains from the mark-up of a cost method investment to fair value upon obtaining control through the acquisition
recorded in Other income (expense).

(5) This includes non-GAAP expenses attributable to redeemable non-controlling interest.
