RELX & Wolters Kluwer: Pushing back on the AI pushbacks Engaging in an AI debate comes with risks. So we found when our ever inventive Director ofResearch came to us with AI-generated pushbacks to our 27 May “Charting a 2027-29 pathto AI reality”. As it happens, they sensibly coincide with real world investors concerns, whichwe address in this more condensed report.

We expect sufficient visibility for users to make informed choices by end 2027. Witha sales cycle of typically of 2-3 years, we assume clarity by end 2029 for all segments, asthe post 2027 sales cycle will have fully played out. We acknowledge the speed at whichthis clarity will emerge is more of a moving target. We assume clarity will emerge faster for “WKL is most exposed, with real risk that high-margin assets get structurally dilutedby free or lower-cost AI-native competitors”1/ WKL risk exposure largely reflects thedifficulty of “grasping” a very diversified portfolio spread across fragmented small, medium BERNSTEIN TICKER TABLE INVESTMENT IMPLICATIONS We rate RELX Outperform with a 3,450p PT, Wolters Kluwer Outperform with a €102 PT DETAILS 27 May 2026 - RELX & Wolters Kluwer: Charting a 2027-29 path to AI clarity6 May 2026 - Quick Take: Wolters Kluwer 1Q revs tracking well vs reiterated FY outlook - UTD Expert AI adoption ramping up29 Apr 2026 - Quick Take: RELX French Legal Tech Doctrine acquisition underlines confidence in Legal AI prospects29 Jan 2026 - Quick Take: RELX - ChatGPT Prism...

Weestimate at current share prices 50% and 90% of RELX & WKL portfolios are implicitly “challenged”.

This reflects •Segments with the highest confidence/lowest risk profile remain in our view those embedded in proprietary content ieessentially within RELX Risk Insurance solutions and US Legal content.
