RELX rises as AI helps with new products and costs

RELX shares rose 1.5% to 2,491p after reporting higher H1 results, including 7% underlying revenue growth and a 9% increase in adjusted operating profit to £1.7B. Margins improved to 35.5% from 34.8%, supported by growing demand for its analytics and decision-making tools.

Analysis

RELX is behaving like a classic compounding quality franchise: the market should read this less as a one-quarter beat and more as evidence that mission-critical analytics still carry pricing power even in a slower macro. The real signal is that margin expansion came without obvious volume leverage, which suggests product mix and pricing are doing more of the work than cost-cutting. That matters because it supports a higher durability multiple versus broad software and information peers that are more exposed to discretionary IT budgets.

Second-order winners are the adjacent data vendors with similarly sticky workflows: S&P Global, Moody’s, LSEG, and Wolters Kluwer should see this as confirmation that enterprise buyers are still paying for decision support, compliance, and workflow integration. The competitive threat is not another legacy publisher so much as AI-assisted substitution: if large-language-model tools can compress the value of search, summarization, and drafting, the first place pressure shows up is in seat growth, not immediately in revenue, because contracts renew slowly. That makes the next 1-3 quarters more important than the headline quarter.

The contrarian read is that the move may be too small to matter unless management turns this into a sustained guidance upgrade path. If demand was truly broadening, we would expect a clearer acceleration in new business or retention metrics, not just better margins. Watch for any sign that margin gains are partly timing-driven; if growth reverts toward mid-single digits or renewal pricing cools, the stock should trade back toward a premium-quality valuation band rather than a growth rerating.

Key Decisions for Investors

• Buy RELX on pullbacks over the next 1-2 weeks only if the stock gives back the initial pop; this is a quality compounder trade, not a momentum chase. Target a 6-12 month hold if management sustains mid/high-single-digit organic growth.
• Pair trade: long RELX / short a more cyclical enterprise software basket or weak information vendor proxy if you want to express 'sticky analytics wins, discretionary IT lags.' Risk to the pair is a broader re-rating of software multiples rather than RELX-specific execution.
• Relative-value watch item: compare RELX versus S&P Global (SPGI) and Moody’s (MCO) into the next reporting cycle. If RELX continues to show better margin progression without sacrificing growth, it supports a premium multiple versus slower-moving peers.
• Set a falsifier alert on any slowdown in underlying revenue growth toward low-single digits or margin mean reversion below ~35% on a sustained basis. That would argue the current move is fully priced and the stock should revert to a cash-generation multiple, not a growth multiple.
