RELX PLC is moving to buy Doctrine, the legal AI firm out of Paris, aiming to strengthen LexisNexis’ legal workflow footprint in Europe. Neither side is sharing the price tag, and for the time being, Doctrine and LexisNexis will remain distinct businesses.
Timing couldn’t be tighter. RELX dropped 1.4% to £26.73 on Tuesday, trailing a modestly positive FTSE 100. The stock is still sitting roughly 36% under its 52-week peak, highlighting persistent questions from investors about RELX’s ability to hold its legal and analytics turf as AI competition heats up.
Founded in 2016, Doctrine pulls together French and other civil-law rulings, statutes and regulatory texts, pairing them with AI for search, drafting, and legal analysis. According to RELX, about 27,000 legal professionals across France, Italy, Germany and Spain now use the platform each day.
Sean Fitzpatrick, chief executive for global legal at LexisNexis Legal & Professional, described Doctrine’s team and platform as a fit with LexisNexis’s global reach. Doctrine CEO Guillaume Carrère said RELX is “the natural next chapter” for their mission. GlobeNewswire
Summit Partners, which backs Doctrine, called the transaction a put option deal—meaning RELX is now on the hook to buy the company, pending talks with French employee representatives as required by law. The sale still faces the usual hurdles: foreign direct investment sign-offs and regulatory green lights.
Just days after RELX stuck to its 2026 forecast, the deal comes through. The company said performance was solid across all four business segments early this year and anticipated robust “underlying” growth—meaning figures stripped of currency shifts, acquisitions, disposals, and event timing—across revenue, adjusted operating profit, and adjusted EPS.

Legal remains the wild card here. RELX reported that law firm and corporate legal segments are showing double-digit growth, helped along by customers embracing its Lexis+ platform, which now features Protégé—an AI legal assistant built right in.
Rob Hales at Morningstar noted RELX didn’t put out any Q1 figures and left its guidance language untouched. Still, he sees the shares as sharply undervalued. Hales added the company’s “wide moat is secure,” despite the information services sector taking a hit from the AI-driven selloff. Morningstar
Management at RELX can point to its 2025 forecasts as a cushion. Adjusted operating profit reached £3.34 billion, with revenue climbing 7% to £9.59 billion. The company also bumped up its full-year dividend to 67.5 pence per share. Chief Financial Officer Nick Luff, speaking to Reuters, said RELX’s advantage lies in deploying its proprietary algorithms on newly refreshed data and content.
RELX continued snapping up its own shares. According to an RNS filing, the company repurchased 4.03 million ordinary shares via J.P. Morgan Securities from April 20 to April 24 and has bought a total of 42.58 million shares since Jan. 2.
The field is only getting more crowded. Just last week, Freshfields and Anthropic announced plans to build legal AI tools together, and Thomson Reuters keeps advancing its CoCounsel offering into legal workflows. For RELX and rivals like Wolters Kluwer, the challenge now is to prove that their proprietary content and specialist workflow platforms can still justify higher price tags.
The concern: AI might be outpacing RELX’s ability to turn its tech into products with clear price tags. Back in February, Schroders analyst Jonathan McMullan told Reuters that the stock slide showed a “deepening structural debate.” He pointed to AI’s velocity as making it tougher to justify long-term valuations, especially after Anthropic’s automation play rattled shares of RELX, Wolters Kluwer and Thomson Reuters.

Right now, Doctrine looks more like a tactical move than a completed transaction. RELX needs to get through employee consultations and regulatory processes before anything’s wrapped, and with the price still under wraps, investors are left guessing if this is a smart, bargain buy for growth or simply a defensive move that could come at a premium.
