(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. 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.

(3) Synopsys' second quarter of fiscal year 2023 and 2022 ended on April 29, 2023 and April 30, 2022, respectively. For presentation purposes, we refer
to the closest calendar month end.

(4) The adjustment includes non-GAAP expenses attributable to non-controlling interest and redeemable non-controlling interest.
