Shearwater Group plc (AIM: SWG) — Investment Research Note
Executive summary
Shearwater is a UK-based cybersecurity buy-and-build group operating two segments — Services (managed security, systems integration, penetration testing, advisory) and Software (SecurEnvoy identity/access management + GeoLang data discovery), selling primarily to UK blue-chip corporates and government. After a painful FY23 (revenue -26%, £6m goodwill impairment) trading has inflected sharply, with FY25 revenue of £39.5m (15-month period) and FY26 tracking to c.£42m and £2.5m adjusted EBITDA — both ahead of consensus 2026-07 FY26 trading update. The single most important valuation point is that at £14.2m market cap the group is trading on c.5.7x FY26E EV/EBITDA (£8.6m EV / £2.5m EBITDA) with £5.6m net cash — a low-teens multiple for a growing niche cyber-services business.
Fair value estimate
- Fair value range: 75p – 110p per share (implied market cap £17.9m – £26.2m)
- Methodology: EV/EBITDA multiple on FY27E adjusted EBITDA, cross-checked against EV/sales.
- Assumptions:
- FY27E revenue: £46m (c.10% growth from FY26E £42m)
- FY27E adjusted EBITDA: £3.0m – £3.5m (margin expanding from 6% toward 7-8% on operating leverage)
- Target EV/EBITDA multiple: 6x – 8x (a discount to listed cyber peers reflecting AIM micro-cap illiquidity, thin margins and mixed track record)
- Add net cash of £5.6m
- Low case: 6x × £3.0m + £5.6m = £23.6m ≈ 99p; but I anchor low to £17.9m/75p to reflect the disappointing Software line and the low-quality Services gross margin (17-20% under new revenue recognition)
- High case: 8x × £3.5m + £5.6m = £33.6m — clipped to £26.2m/110p to avoid crediting the AI-cross-sell narrative
- Vs. current £14.2m market cap: mid-point £22m implies +55% upside (range: +26% to +85%)
- Cross-check: on FY26E EV/sales of 0.2x, peers (Kape, Corero, Osirium historically) traded 1-3x; even 0.4x sales for the mid-point would imply a £22m EV / £27m market cap.
Sector context
- ICB Technology / Software & IT Services confirmed.
- Quality/growth profile is below typical cybersecurity peers: gross margins are Services-industry-typical low-20s%, not SaaS-like 70-80%; EBITDA margin is 6% vs. 15-25% for scaled cyber names. Balance sheet quality is above peer average (net cash, no debt).
- Listed comparables: Corero Network Security (LON: CNS — DDoS, UK AIM), Kape Technologies (delisted, prior peer), NCC Group (LON: NCC — larger cyber-services). Also loosely comparable: Osirium Technologies (LON: OSI, PAM software).
Investment thesis
- Sharp trading inflection with beats above consensus in FY25 and FY26. FY26 revenue of c.£42m and adjusted EBITDA of £2.5m are above broker estimates of £35.5m/£2.4m, extending the run from FY24 (£22.6m / £0.9m) 2026-07 FY26 trading update.
- Fortress balance sheet at a micro-cap valuation. £5.6m net cash represents c.40% of market cap; the board is now seeking shareholder approval to reallocate reserves to enable buybacks and/or a dividend 2026-07 FY26 trading update. Downside is protected by tangible cash and by G-Cloud framework revenue visibility.
- Genuine cybersecurity beneficiary of AI-driven attack surface expansion. Management explicitly cites "accelerated integration of AI across our end markets that increasingly fuels the need for secure systems" and has secured major multi-year contracts (£7.3m mobile operator extension, £9m financial services renewal, £12.9m 5G monitoring, $12.8m telco) that speak to real demand 2026-03 interim; 2024-11 interim.
Key risks
- Gross margin quality is weak and structurally opaque. Under the revised IFRS revenue policy, Services gross margin was 17% in H1 FY26 vs. 24% restated prior year, driven by cloud-hosted/reseller mix. Small changes in mix drive large swings in EBITDA on this cost base 2026-03 interim.
- Concentration and lumpy revenue. One customer accounted for £8m of FY23 revenue (30% of group); H1 FY26 accounted for £1.5m of receivables timing that pushed period-end cash to £2.2m. Loss or delay of a single major contract is a material profit event 2023-09 final results; 2026-03 interim.
- Long history of missing expectations and volatile results. FY24 revenue came in at £22.5m vs. £32.5m consensus (a 31% miss), and FY23 also missed materially; the two recent beats need to be seen against a longer pattern of misses, and this remains a sub-scale (£14m cap) AIM stock with limited analyst coverage 2024-04 FY24 trading update; 2023-03 trading update.
Operating leverage
Shearwater's cost base is modestly fixed but not the classic high-operating-leverage SaaS profile. Central group costs of £1.3-1.8m plus divisional overheads of c.£5-6m give a fixed cost floor of c.£7m, against gross profit of £6-10m. The Software segment (11% of revenue) has genuine leverage — 62-72% gross margin and 36-40% EBITDA margin at just £2.6m revenue 2026-03 interim — but is too small to move the group. The Services segment, which dominates, runs at 17-22% gross margin because much revenue is pass-through reseller/licensing where cost of sales scales 1-for-1. The result: a 10-20% revenue beat likely converts to a c.£0.8-1.5m EBITDA uplift (i.e. +30-60% on £2.5m EBITDA) — meaningful but not "multiples of profit." The most promising leverage vector is the Software division scaling on its existing R&D base: incremental software licence revenue would drop at 60%+ contribution margin. The G-Cloud 15 expansion (from 32 to 55 products) is the near-term catalyst 2026-03 interim.
Value-trap signals
- Revised revenue recognition policy (announced FY25) that materially reduces headline Services gross margin — needs monitoring for further changes.
- £6m goodwill impairment in FY25 and a further £6m in FY23 across SecurEnvoy/Xcina — 30% of net asset value has been written off since FY22.
- £47m accumulated losses vs. £22m share capital / £34m share premium — the group has cumulatively destroyed capital across its buy-and-build history.
- Software revenue declining — down 12% YoY in H1 FY26 despite being the higher-margin segment.
- Historic pattern of guidance misses (FY23, FY24) before recent beats.
- 19% related-party (director) stake — governance to watch though voting alignment is a positive.
Earnings vs. expectations
- FY22 (Jul 2022): revenue £35.9m vs. no explicit prior guidance — beat with EBITDA £4.4m ahead of expectations.
- FY23 (Mar 2023 update): revenue £27m vs. consensus £37.7m, EBITDA breakeven vs. £4.4m consensus — material miss.
- FY24 (Apr 2024 update): revenue £22.5m vs. consensus £32.5m, EBITDA £1m vs. £2.5m — material miss.
- FY25 (Jul 2025 update): revenue £41m vs. consensus £39m, EBITDA £2.2m vs. £2.0m — beat.
- FY26 (Jul 2026 update): revenue £42m vs. consensus £35.5m, EBITDA £2.5m vs. £2.4m — beat. Pattern: two large misses (FY23, FY24) followed by two consecutive beats (FY25, FY26). Recent execution has clearly improved under Higgins/Hall, but the four-year track record is mixed and the base rate of guidance reliability is not yet re-established.
Conviction
Conviction: 3 (moderate).
Supporting: (i) two years of consistent, above-consensus delivery with the beats confirmed via inside-information RNS; (ii) fortress balance sheet with £5.6m net cash and imminent capital-return authorisation, providing a hard downside anchor; (iii) low multiple (c.3.4x EV/EBITDA on FY26E) means even a conservative peer-relative multiple generates upside without a re-rating narrative.
Limiting: (i) recurring accounting-policy changes and repeated £6m goodwill impairments make historical comparisons unreliable and cast doubt on prior earnings quality; (ii) demonstrated 30%+ downside surprise on revenue in both FY23 and FY24 — a repeat would collapse the thesis, and the concentrated customer book makes this a live risk at this scale.
Driver commentary
- AI beneficiary: Genuine cybersecurity exposure, augmented by rising AI-driven threat surfaces (management commentary is credible, not just marketing). But scale is tiny and value capture is dominated by reseller pass-through rather than proprietary IP.
- Operating leverage: Moderate. Software subsegment has real leverage but is 11% of revenue; Services is largely reseller economics.
- Cyclicality: Low — cyber budgets are non-discretionary; FY23 miss was execution/timing, not cyclical.
- Moat: Narrow — differentiation is relationships and specific product accreditations (G-Cloud, defence-cleared MFA); no network effects.
- Leverage: Net cash, no debt — fortress.
- Earnings quality: Weakest driver. Revenue-recognition changes, large goodwill write-offs, "adjusted EBITDA" that excludes £0.7-1m annual amortisation of acquired intangibles that are real economic costs.
- Growth momentum: Strong right now — two consecutive beats, contract pipeline visible.
