RingCentral (RNG) is breaking out to new 52-week highs following a strong 4Q25 beat-and-raise performance, underscored by accelerating profitability, rising AI monetization, and expanding capital returns. EPS grew 20% yr/yr to $1.18, topping expectations, as non-GAAP operating margin expanded 140 bps to 22.8%, driven by operating leverage, improved sales and marketing efficiency, disciplined hiring, offshoring, vendor consolidation, and increased internal AI usage. Record free cash flow of $126 mln in Q4 (+13% yr/yr) capped a year in which FCF surpassed $500 mln, reinforcing confidence in the durability of the model. Reflecting that strength, RNG initiated its first-ever quarterly dividend of $0.075 per share and increased its share repurchase authorization to $500 mln.

• Non-GAAP EPS rose 20% to $1.18 as margin expanded to 22.8%, benefiting from revenue growth outpacing expense growth, SBC reduction (down over 300 bps as a % of revenue), and tight cost controls.
• AI-powered products reached $100 mln in ARR, with pure AI ARR nearly tripling yr/yr and ARR from AI-utilizing customers now approaching 10% of total ARR, more than doubling yr/yr.\
• AI portfolio momentum is being driven by AIR (AI Receptionist), AVA (AI Virtual Assistant), and ACE (AI Conversation Expert), which automate, assist, and analyze customer interactions; AIR customer count reached 8,300 (+44% sequentially), while ACE customers climbed 144% yr/yr.
• AI-utilizing customers exhibit higher ARPU and net retention rates above 100%, creating a structural tailwind as AI attach rates are meaningfully higher in new logo wins.
• Q4 free cash flow hit a record $126 mln, up 13% yr/yr, supporting both balance sheet deleveraging and enhanced shareholder returns.
• RNG is targeting 20% GAAP operating margin over the next 3-4 years, driven by sustained 80%+ subscription gross margins, operating leverage, SBC reduction toward 3-4% of revenue, internal AI efficiencies, and disciplined expense growth.
• For 1Q26 and FY26, RNG guided above expectations on both revenue and EPS, calling for FY26 non-GAAP EPS of $4.76-$4.97, non-GAAP operating margin expansion to 23.0-23.5%, GAAP margin near 9% at midpoint, and FCF of $580–$600 mln.

Briefing.com Analyst Insight

RNG’s quarter highlights a company successfully pivoting toward AI-led growth while expanding profitability. AI is no longer conceptual -- it is monetizing meaningfully, with $100 mln in ARR and nearly 10% of total ARR tied to AI-utilizing customers who spend more and churn less. The agentic voice AI strategy, centered on AIR, AVA, and ACE, positions RNG at the top of the B2C communications funnel, enhancing stickiness and expanding wallet share. Margin expansion is being fueled by structural cost discipline, SBC reductions, and operating leverage, while subscription gross margins remain above 80%. Importantly, FY26 guidance signals continued EPS and FCF growth alongside further margin expansion, supporting both reinvestment and capital returns. With a new dividend and expanded buyback, RNG is demonstrating confidence in durable cash flow generation as it transforms into an AI-driven communications platform.
