RIGHTMOVE PLC (RMV) — Investment Research Note

Executive summary

Rightmove operates the UK's dominant residential property portal, monetising estate agents and new-homes developers through subscription packages and incremental digital products on a near-monopolistic network (c.90% share of time per Comscore, >80% direct/organic traffic) 2026-07 half-year. Across the five-year window revenue has compounded at a mid-to-high single-digit pace (£289m 2019 → £425m 2025 → guided £450m 2026E), with underlying operating margin holding in the high-60s–low-70s even through heavy platform investment and AI integration. The single most important valuation point today: the stock trades at c.14–15× FY26E underlying EPS versus a historical 20–30× range — a monopoly digital network with 69% underlying margins is being offered at a discounted multiple, largely because of a lowered 2026 revenue guide (6–8% vs 8–10%) and the overhang of a £1.56bn CAT class-action certification hearing in November 2026 2026-07 half-year.

Fair value estimate

Methodology: forward P/E (primary) cross-checked against FCF yield.

• FY26E underlying EPS: c.30.5p (2025 base 29.1p × ≥5% guided growth) 2026-07 half-year
• Target multiple range: 16–19× — justified by: 69% operating margin, >100% cash conversion, c.90% direct-traffic moat, mid-single-digit organic growth, limited balance-sheet risk. Lower than the 2017–2022 average (c.25×) to reflect slower top-line, legal overhang, and the newly introduced leverage.
• Implied per-share: 490p – 580p, midpoint 535p
• Implied market cap: £3,553m – £4,205m, midpoint £3,879m
• FCF cross-check: 2025 operating cash £308m, capex c.£10m → c.£298m free cash → at midpoint market cap of £3.9bn implies 7.7% FCF yield (reasonable for a durable asset-light compounder).

Vs current £3,281m (442.8p): absolute upside c.+18% to midpoint, range -3% to +31%.

Sector context

Confirmed as Real Estate (ICB), though RMV is a classified-advertising / vertical-SaaS business economically rather than a landlord. Its quality profile is well above the sector average: no property on balance sheet, no cyclical rental income, 69% operating margin vs sub-20% for most REITs. Nearest listed comps are the global property portals: REA Group (ASX:REA), CoStar (NASDAQ:CSGP), and (loosely) Zillow (NASDAQ:Z). On financial profile RMV sits closest to REA — both are near-monopoly local portals with high-60s margins and dominant network effects.

Investment thesis

1. Monopoly network with pricing power that remains underutilised. Agency ARPA grew 8% in H1 2026 (+£116 to £1,636/month) through package upgrades and new products despite flat membership, and Agency retention hit the highest level in over 10 years at 96% 2026-07 half-year. Three years of mid-single-digit ARPA growth without customer attrition demonstrates genuine pricing power, not elasticity-limited revenue growth.

2. Operating leverage to AI-adjacent product monetisation. "Ask Rightmove" conversational search drove a c.40% uplift in average time on site and nearly double the lead-send propensity; AI-enabled Online Agent Valuation drove c.50% more unique valuation leads to agents and was the fastest-growing new product ever 2026-07 half-year. These are AI products whose incremental revenue drops directly to the bottom line on a 69%-margin cost base.

3. Valuation discount creates asymmetric payoff. Shares derated from 668p (Oct 2025) to 442.8p — c.-34% — on the New-Homes-driven guide reduction and legal overhang, pushing the forward P/E to c.14–15× vs a 20–30× historical range. The Board has backed its own view of value with a £200m RCF funding c.£330m of buybacks on top of the dividend, a step-change in capital return 2026-07 half-year.

Key risks

1. £1.56bn Competition Appeal Tribunal class action. Certification hearing November 2026; management says claim is "without merit" and 2026 exceptional costs are £4-7m, but adverse certification or ruling could materially affect valuation and sentiment 2026-07 half-year.

2. New Homes end-market structurally weak. Development listings fell 6% YoY in H1 2026 to lowest level in over a decade; management warns conditions among worst since GFC. Direct cause of the 2026 revenue guidance cut and a drag on >10% of group revenue 2026-07 half-year.

3. AI-driven disintermediation risk. <0.5% of H1 2026 traffic came from LLMs, but this is a key emerging risk disclosed in the principal-risks section; a consumer shift to AI agents searching across property datasets could erode the network effect that underpins the moat 2026-07 half-year, inferred structural risk.

Operating leverage

Rightmove is a textbook high-operating-leverage business. The underlying cost base in H1 2026 was £70.7m against revenue of £225.8m, implying a c.69% underlying operating margin. The great majority of costs are fixed: payroll (c.60% of the cost base — H1 2026 employee benefits £41.4m across 935 FTEs), cloud infrastructure, and marketing — none of which scales with ARPA or new product uptake. Gross margin is effectively >95% (there is virtually no cost of revenue in a subscription portal). A 10% revenue beat vs current £450m guidance (c.£45m incremental revenue) would, at a c.90% incremental contribution margin, add c.£40m to operating profit on a base of c.£300m — a c.13% profit uplift from a 10% revenue beat. A 20% beat compounds non-linearly as marketing and fixed R&D leverage further; incremental contribution margins on existing-customer upsell approach 95%. The clearest observable inflection points: (i) Strategic Growth Areas (Commercial, Rentals, Mortgages) grew 14% in H1 2026 against guidance of 20–30% full-year growth and already generate £17.5m revenue 2026-07 half-year — these ride on the same fixed platform; (ii) Agency membership stabilising with Optimiser Edge penetration at 36% and still climbing 2026-07 half-year.

Value-trap signals

None of the classic value-trap red flags are present. Revenue is still growing (not declining), the balance sheet is pristine (modest £200m RCF just drawn to fund buybacks, not operations), dividends have been raised, auditor is unqualified, there are no related-party concerns, and the £1.56bn legal claim is disclosed and management is fighting it. The one yellow flag worth flagging: 2026 revenue guidance was cut mid-year (8-10% → 6-8%) — the first visible guidance miss in several years, and worth watching if repeated.

Earnings vs. expectations

Across the filings, Rightmove has a strong track record of meeting or marginally beating its own guidance:

• FY2024: delivered revenue £389.9m / +7% (within 7-9% guidance), 70% underlying margin (in line) — in line.
• FY2025: guidance 8-10% revenue, 70% margin; delivered £425.1m / +9%, 70% margin — in line / modest beat.
• H1 2026: reiterated FY guidance at AGM (8-10% revenue); cut at H1 to 6-8% in July 2026 due entirely to New Homes volumes — first visible miss vs own guide.

Analyst consensus is not disclosed in the filings; the November 2023 trading update noted trading "marginally ahead of consensus expectations" 2023-11 trading statement. Pattern: a company that previously consistently met its own guidance has now had one external-market-driven downgrade — not a credibility problem yet but worth monitoring.

Conviction

Conviction: 4 (high).

Anchoring factors: (1) exceptionally clean financials and consistent 5-year disclosure with unqualified audits by EY; (2) the business model is simple and the valuation methodology (forward P/E on highly cash-converting underlying earnings) is unambiguous; (3) multiple cross-checks (P/E, FCF yield, and management's own willingness to lever the balance sheet to buy back shares) all point in the same direction.

Limiting factors: (1) the £1.56bn CAT class action adds genuinely uncapped downside and makes any precise fair-value point suspect; (2) the AI disintermediation question is unanswerable from the filings — current data (<0.5% LLM traffic) is reassuring but 5-year forward is unknowable.
