Earnings call transcript: Quartix Holdings PLC sees strong growth in H2 2025

Quartix reported revenue of GBP 35.7m, up 12% YoY, operating profit of GBP 8.7m, up 34%, and free cash flow doubled to GBP 5.2m; EPS rose to GBP 0.1318. ARR ended at GBP 37m with 334,000 subscriptions (up 11%), ARR growth +GBP 4.5m, and 47% of ARR outside the U.K.; management cited product rollouts (plug & track, connected dash cam) and indirect sales expansion as priorities. The company benefited from lower 4G unit manufacturing costs and the closure of loss-making German subsidiary Konetik, while an accounting policy change reclassifying trackers as PPE had offsetting P&L effects. Shares jumped 10.85% to close at GBP 235 (from 212) on the results; no numeric 2026 guidance was provided.

Analysis

Quartix’s results reveal more than a one-off beat — they expose a business moving from hardware-heavy economics toward higher-margin recurring software through two levers: cheaper, user-install hardware and higher-value connected peripherals. That combination amplifies free cashflow sensitivity to ARR growth: a modest acceleration in subscription additions or ARPU can flow disproportionately to the bottom line because marginal cost per incremental vehicle is falling and payback periods on customer acquisition compress.

Be cautious on headline margin expansion: the firm’s accounting reclassification lengthens the depreciation horizon for installed units, smoothing costs into the balance sheet and inflating near-term operating metrics vs the old treatment. This creates a timing arbitrage — the market may price in permanent margin improvement while the underlying cash cycle and replacement/upgrade costs still carry multi-year tails and potential lumpiness.

Product and go-to-market dynamics are the primary catalysts and risks. A successful U.S. roll-out of the new self-fit unit and a scalable indirect channel could unlock a multi-year TAM re-rate; conversely, supplier concentration on the new 4G units or delays in type approval could produce sudden incremental costs and churn in regions undergoing legacy network upgrades. Watch short-term NRR trends and ARR bookings over the next 2-6 quarters as the real test of sustainable growth and monetization of dash-cam data networks.

Key Decisions for Investors

• Long Quartix (LSE: QTX) — tactical core position (2–3% portfolio) with a 12–18 month horizon. Rationale: asymmetric upside if ARR acceleration and indirect-channel rollout execute; target +30% total return. Risk control: set a hard stop at −12% and trim to half size on +20% move.
• Call-spread alternative — buy a 12–15 month QTX call 20–25% OTM and sell a further OTM call 45–50% above entry to finance cost. Rationale: levered exposure to successful Plug & Track U.S. type approval and dash-cam rollouts with defined downside (premium lost). Appropriate size: <1% notional of portfolio.
• Pair trade to isolate execution risk — long QTX / short MiX Telematics (JSE: MIX) or a larger hardware-exposed peer, equal notional. Rationale: expresses view that Quartix’s software-upgrade and unit-cost gains will re-rate faster than hardware-heavy players; expected alpha over 6–12 months if Quartix NRR holds. Manage: close if pair diverges >15% or if Quartix NRR falls below 97%.
• Hedge against accounting/operational re-rate — buy a 3–6 month put spread on QTX (e.g., 10–20% OTM long put funded by selling deeper OTM put). Rationale: protects downside from a reversion in market multiple driven by scrutiny of the accounting change or a product delay. Limit size to 0.5–1% portfolio.
