Non-GAAP Operating Income excludes stock-based compensation expense, amortization of acquired intangible assets, Finance transition cost, and other non-recurring items. Non-GAAP Net Income further adjusts for the related tax effects on the above items. 3. Free Cash Flow is defined as net cash provided by (used in) operating activities less capital expenditures. Free Cash Flowdoes not represent residual cash flow available for discretionary expenditures. 4. Bookings for the Data & AI segment are defined as the total contract value of new engagements entered into during a specified period, including adjustments for changes in contract scope and early terminations. Bookings are not necessarily indicative of future revenues, as actual realization depends on project execution and client retention. 5. Billable Headcount represents the number of revenue-generating consultants actively deployed on client engagements as of the last business day of the reporting period. This metric excludes bench personnel and internal support staff. 6. Average Bill Rate is calculated as total Talent segment revenue divided by cumulative billable hours of deployed consultants during the reporting period, expressed as an hourly rate. 7.
