In Q3 25, the Company updated its definition of PitchBook licensed users, primarily to remove Morningstar and PitchBook users. Q3 24 user counts reported here reflect the updated methodology. Please see p. 50 of this presentation for more information. The timing of activities, such as user maintenance, user audits, provisioning access, shutting off of users, and updates to the user lists when enterprise clients renew, results in fluctuations in licensed user counts over time. As a result, licensed user growth trends are best assessed on a rolling 12- month basis. 0.0% 18,767 18,771 Morningstar Direct Licenses Q3 24 Q3 25 0.0% 113,410 113,453 PitchBook Platform Licensed Users* Q3 24 Q3 25

Appendix C: Additional Information 50 In Q3 25, the Company updated its definition of PitchBook licensed users, primarily to exclude Morningstar and PitchBook employees. The historical time series presented here reflects the updated definition. The sequential decline in licenses between Q2 25 and Q3 25 is largely due to the rationalization of licensed user lists associated with recent large renewals. 96,016 99,830 102,795 109,543 113,410 113,447 114,259 116,421 113,453 PitchBook Licenses - Updated Methodology Q3 23 Q4 23 Q1 24 Q2 24 Q3 24 Q4 24 Q1 25 Q2 25 Q3 25 0 15 30 45 60 75 90 105 120 PitchBook Licensed-User Definition PitchBook Platform Licensed Users* *Prior to Q3 25, the PitchBook platform licensed user count reflected active users, including Morningstar and PitchBook active users. In Q3 25, the Company updated its definition of PitchBook licensed users, primarily to remove Morningstar and PitchBook users. The timing of activities, such as user maintenance, user audits, provisioning access, shutting off of users, and updates to the user lists when enterprise clients renew, results in fluctuations in licensed user counts over time. As a result, licensed user growth trends are best assessed on a rolling 12-month basis. 51 New Investor Q&A Schedule For questions received by 5pm CT on: Expected 8-K Response Date: Nov. 5, 2025 Nov. 25, 2025 Dec. 5, 2025 Dec. 23, 2025 Jan. 5, 2026 Jan. 26, 2026 March 5, 2026 March 25, 2026 Starting in November 2025, the Company is implementing a schedule for its responses to investor questions.
