QUARTIX TECHNOLOGIES PLC (QTX) — Investment Research Note
Executive summary
Quartix is a UK-based subscription vehicle telematics vendor serving ~33,550 small-to-medium fleet customers (~343,000 vehicles) across the UK, France, USA and expanding continental European markets, with 97% of revenue recurring. Since founder Andy Walters returned as Executive Chairman in late 2023, the group has re-focused on organic ARR growth, delivered accelerating gross margins (80.0% H1 2026), and grown ARR by 11–14% p.a. while more than doubling free cash flow between 2024 and 2025. The most important valuation point today: this is a genuinely high-quality, cash-generative, net-cash subscription business trading at a modest premium to a fair intrinsic value — attractive to a quality-at-a-reasonable-price investor, but with only tangential AI exposure.
Fair value estimate
Range: 260p – 320p per share, implied market cap £126m–£155m.
- Methodology: blended DCF and forward P/E cross-check.
- Forward earnings multiple: FY26 consensus Adj EBIT £10.1m 2026-07-27 interim, ~23% underlying tax (H1 2026 underlying tax £1.1m on £4.8m PBT 2026-07-27 interim) → ~£7.8m normalised earnings ≈ 16.1p normalised EPS. At 16-20x forward earnings (justified by 97% recurring revenue, 80% gross margin, net-cash balance sheet, 24%+ Adj EBIT margin), fair value = 258p–322p.
- EV/EBITDA cross-check: FY26e EBITDA guidance ~£15m 2026-07-08 trading; 8-10x = £120-150m EV + £5m net cash = 258p–320p.
- FCF cross-check: FY25 FCF £5.2m 2026-03-25 final; FY26 guidance £4.9m 2026-07-08 trading. At 4-5% FCF yield fair range = 200p-260p (lower end of range).
- Central estimate: 290p per share / £141m mcap.
- vs. current mcap £122.6m: absolute upside ≈ +18.5% to mid, range −0% to +30%.
Sector context
- ICB Technology / Software & Computer Services classification is accurate: this is subscription vertical SaaS with an integrated hardware element (now on-balance-sheet under IAS 16 following the 2025 FRC review 2026-03-25 final).
- Quality profile is above typical AIM technology peers: consistently profitable, cash-generative, net cash, high recurring revenue, low customer concentration (largest client <1% of sales 2025-10-06 trading).
- Listed peer set is thin. Nearest UK-listed comparators: Microlise Group (SAAS) (larger fleet tech, lower gross margin), Trakm8 (TRAK) (smaller, more volatile), AB Dynamics (ABDP) (adjacent automotive tech, richer valuation). International peers Samsara (US) and Geotab (private) operate at very different scale and multiples.
Investment thesis
- High-quality subscription compounder trading at a reasonable price. 97% recurring revenue, 80% gross margin (H1 2026, restated basis), 24% Adj EBIT margin, £4.8m net cash and NRR of 96.9% 2026-07-27 interim. Blended forward multiple of ~15x earnings understates the durability of the cash flow stream.
- Continental Europe is the growth engine and it is executing. Italy ARR +39%, Spain +31%, Germany +20%, France +14% TTM to June 2026 2026-07-27 interim; management is stepping up investment into H2 2026 and 2027 including dashcam launch in Continental Europe 2026-07-27 interim. This structurally lifts group growth above the mid-single-digit UK rate.
- Operational discipline post-Konetik cleanup. The Konetik acquisition was written off in full 2024-03-04 final and management pivoted decisively back to core telematics; TCSV17/18 hardware refresh cuts unit cost, FY25 FCF doubled to £5.2m 2026-03-25 final, and the group returned 10p total dividend for 2025 (vs 4.5p 2024).
Key risks
- AI-agent substitution risk to the value proposition is low but not zero. The core buyer is a tradesperson SME; if a future AI-driven fleet automation product from a hyperscaler bundled telematics as a commodity feed, per-vehicle ARR could compress. Not disclosed but inferred.
- Slowing NRR and US churn. Group NRR slipped to 96.9% from 97.3% 2026-07-27 interim; US subscription base declined 3% TTM. If UK NRR continues to drift (100% → 99.4% 2026-07-27 interim), the compounding thesis weakens.
- Accounting policy volatility raises watch-flags. The FRC-driven IAS 16 restatement in 2025 2026-03-25 final materially altered the P&L geography and produced a £1.1m prior-year tax adjustment in H1 2026 2026-07-27 interim. The auditors' report is unqualified but the episode shows that reported EBITDA has been sensitive to accounting choices.
Operating leverage
The cost base is substantially fixed — ARR per employee reached £220,000 in H1 2026 (from £198k a year earlier 2026-07-27 interim), gross margin is 80%, and administrative expenses grew only 2% on 12% revenue growth in H1 2026 2026-07-27 interim. Under IAS 16, incremental subscriptions carry an immediate cash cost (unit + install) but are depreciated over 7 years, so reported P&L operating leverage on ARR growth is high: H1 2026 gross profit grew £1.9m on £2.1m revenue increase — near-90% incremental gross margin. A 10-20% revenue beat above the current £40.3m consensus would plausibly add £3–5m to Adj EBIT (£10.1m → £13–15m), i.e. a 30-50% profit uplift — meaningful but not multiples of profit, because management would likely reinvest a portion into sales/marketing (as the H1 2026 £1.0m S&M step-up demonstrates 2026-07-27 interim). This is a solid but not extreme operating-leverage story: the "spare capacity" is real, but growth is a steady 11-14% ARR compounder, not a runaway top-line.
Value-trap signals
None identified of concern. Minor watch-items: (i) the FRC restatement is not a value trap but a reminder to read the reconciliations; (ii) US and UK NRR softness bears monitoring; (iii) Konetik was a poor capital-allocation decision, since fully cleaned up.
Earnings vs. expectations
Across the 2024–2026 period Quartix has consistently met or modestly beaten market expectations. H1 2025: management raised guidance to "slightly ahead" 2025-07-24 interim. FY 2025 trading update Jan 2026: revenue and EBITDA "ahead of current market expectations" 2026-01-08 trading update. H1 2026 interim confirmed FY market expectations of £40.3m rev / £10.1m Adj EBIT / £4.9m FCF 2026-07-27 interim. The 2023 Konetik-related impairment was the last material downside surprise, and the last four consecutive result cycles have been in-line to marginally ahead. Track record supports moderate confidence in the current-year guide.
Conviction
4 — high. Anchoring the fair value: (i) 97% recurring revenue with 22+ years of subscription-based track record gives high confidence in near-term revenue; (ii) management guidance has been reliable for four consecutive reporting cycles; (iii) multiple valuation methodologies (P/E, EV/EBITDA, FCF yield) converge on £120–150m. Limiting the conviction: (i) the recent IAS 16 restatement means historical margin trajectory needs re-normalising, adding noise to the multi-year picture; (ii) the terminal growth rate for a mature SME telematics business is uncertain — 4–5% or lower is plausible in a mature market, which caps DCF-implied value.
