Comparing Sage and RELX: Which UK Software Stock to Buy?

Overview:

• Sage: Strong cloud revenue and recurring subscriptions support its long-term growth outlook.

• RELX: A lower forecast P/E ratio and higher expected dividend yield make it attractive to value-focused investors.

• Investment choice: RELX offers better value, while Sage may appeal to investors who prefer faster software growth.

Sage and RELX represent two distinct pathways for investors seeking long-term expansion within the UK market. Sage provides payroll, accounting, and business software, whereas RELX delivers data, analytics, and research to scientific, legal, and commercial clients. Both maintain deep customer relationships, but RELX presents a more compelling valuation, while Sage achieves faster revenue acceleration.

Sage Delivers Strong Cloud Growth

During the first nine months of fiscal 2026, Sage posted underlying revenue of GBP 2.062 billion, representing an 11% increase. Sage Business Cloud turnover advanced 15% to GBP 1.762 billion, while recurring revenue hit GBP 2.002 billion, also up 11%. Software subscription revenue improved by 13%, with subscriptions now accounting for 84% of the total revenue stream.

These figures highlight the company’s heavy reliance on recurring payments rather than standalone software transactions. Because small and medium-sized enterprises depend on its payroll and accounting tools for daily operations, cost tracking, and regulatory tax compliance, demand for these utilities typically remains resilient during economic slowdowns.

Sage anticipates organic revenue expansion surpassing 9% for fiscal 2026 alongside enhanced operating margins. The firm has additionally pursued growth via cloud and artificial intelligence acquisitions. On October 5, it unveiled agreements for WholeHelp and Moovin’Cloud, following an October 1 deal for Paperless that offers an additional avenue for expansion. Although these transactions could accelerate cloud transition and task automation, each buyout carries inherent execution risks.

RELX Combines Profit Growth with a Lower Valuation

RELX generated GBP 4.871 billion in revenue throughout the first half of 2026, marking a 7% underlying improvement. Adjusted operating profit climbed 9% to GBP 1.727 billion, and adjusted earnings per share advanced 11% at constant exchange rates to reach 68.6 pence. An adjusted cash-flow conversion rate of 98% demonstrates robust cash generation capabilities.

Through businesses like LexisNexis, RELX offers specialised decision support tools and information services. Corporate entities, researchers, and legal professionals depend on these platforms for reliable data. Its proprietary assets and niche instruments may help preserve its market standing as artificial intelligence transforms information discovery.

The interim payout rose by 7% to 20.9 pence per share alongside ongoing share repurchases. RELX fulfilled GBP 1.75 billion of a planned GBP 2.25 billion buyback initiative during the opening half of the year, with an additional GBP 400 million scheduled prior to the close of December. Conversely, leverage warrants attention, as the net debt-to-EBITDA ratio registered at 2.3 times as of June.

Share Prices Favor RELX on Value

At the close of trading in London on October 15, 2026, shares of Sage traded at GBP 11.335 while RELX stood at GBP 28.86. Sage gained 5.64% during the session, lifting its year-to-date performance to 4.66%. RELX advanced 4% on the day but remains down 4.44% across the year.

Consensus market forecasts place Sage’s fiscal 2026 price-to-earnings multiple at 25.5 times, compared to 22.4 times for RELX. Looking to fiscal 2027, these multiples contract to 21.7 times for Sage and 20 times for RELX. Projected dividend yields for 2026 sit at 2.07% for Sage and 2.53% for RELX.

For income- and value-oriented investors, these metrics grant RELX the advantage due to its reduced forecast multiple and superior yield. Nonetheless, a lower valuation does not guarantee enhanced returns, as future profitability, market sentiment, and entry prices all influence ultimate outcomes.

AI Creates Both Opportunity and Risk

Artificial intelligence presents both expansion prospects and new challenges for both entities. Sage can leverage the technology to streamline administrative finance procedures, elevate client support, and enhance its cloud applications, with rapid top-line growth attracting proponents of enterprise software subscriptions.

RELX can integrate AI into data analytics, legal research, and targeted decision platforms. Because certain investors worry that emerging AI products might cannibalize demand for legacy research services, RELX must demonstrate the enduring value of its proprietary data and specialized instruments against competing offerings.

Additionally, RELX must navigate debt expenses and maintain strong liquidity. Sage faces a distinct hurdle: its elevated valuation leaves minimal margin for error regarding missed targets or decelerating growth. Both companies demand careful tracking of earnings, profit margins, and customer demand.

Final Verdict: RELX has the Edge

For value-seeking participants prioritizing steady profit progression, dividend distributions, and buybacks, RELX emerges as the more compelling option. A modest projected price-to-earnings ratio and robust cash flows support this view, though debt burdens and AI vulnerabilities require close monitoring.

Conversely, Sage may suit investors prioritizing rapid software expansion who are comfortable accepting a higher valuation. Robust cloud income and an extensive subscription foundation represent core advantages, while recent corporate acquisitions could unlock fresh growth channels.

The upcoming catalyst for RELX is its nine-month trading update scheduled for October 22, 2026, where observers will look for sustained top-line momentum and a reaffirmed full-year outlook. For Sage, key indicators include maintaining organic growth above 9%, preserving subscription income, and expanding operating margins. Ultimately, the superior investment will be the enterprise that successfully translates current strengths into enduring earnings expansion at a reasonable price.
