Segment Reporting [Abstract]  
Reconciliation of Revenues and Income from Segments to Consolidated Asset information by segment is not presented, as this measure is not used by the chief executive officer, who is the chief operating decision maker ("CODM"), to assess the Company’s performance.
For all segments, the CODM uses segment revenue and segment profit in the annual budgeting and forecasting process. The CODM considers budget-to-actual variances on a monthly and quarterly basis for both segment revenue and profit when making decisions about allocating operating and capital resources to the segments. The CODM also uses segment revenue and profit to assess the performance for each segment by comparing the results of each segment with one another and in determining the compensation of certain employees.

Effective January 1, 2026, the Company will be updating its segment reporting to align with industry evolution, its updated operating model, and how internal reporting will be provided to the CODM. As a result, the Contract Sales & Medical Solutions segment, which has become more closely related operationally to the Technology & Analytics Solutions segment commercial offerings, will be incorporated into the Technology & Analytics Solutions segment, which is renamed Commercial Solutions. Additionally, Real-World Late Phase and certain other Real-World offerings that have become more closely related operationally to the clinical research business, will be moved from the Technology & Analytics Solutions segment to the Research & Development Solutions segment. The Company will reflect the recast of segment information on this basis beginning with its Form 10-Q for the three months ended March 31, 2026.
The Company’s reportable segment information is presented below:
