Overview
RELX is a UK-listed information and analytics group with four segments: Risk (LexisNexis Risk Solutions), Scientific/Technical/Medical (Elsevier), Legal (LexisNexis Legal & Professional), and Exhibitions (RX). The moat is strongest in Risk and Legal where proprietary datasets and integration into customer workflows (fraud/identity, compliance, legal research/drafting) create recurring revenue and switching costs. STM combines content rights with research platforms (e.g., ScienceDirect and research intelligence tools) that are embedded in institutional workflows, supporting pricing power but facing open-access and procurement pressure. Exhibitions has more cyclical economics; advantages are mainly event brand strength and two-sided marketplace dynamics at flagship events, aided by digital/data tools. Market cap as of 2025-12-29: ~USD 74.83B (Yahoo Finance: https://finance.yahoo.com/quote/RELX/).
