TPXimpact Holdings PLC (TPX) — Investment Research Note

Executive summary

TPXimpact is a UK AIM-listed digital-transformation services firm that derives over 90% of revenue from UK public-sector clients (Central Government, HMLR, NHS, HMPPS, DEFRA, DfE, MHCLG). Across the five-year window the group has gone through acquisition-led expansion, a severe post-election revenue shock in FY25, and a successful three-year turnaround that culminated in FY26 adj EBITDA of c.£8.6m, 11.0% margin and net debt of c.£4.2m, materially ahead of consensus 2026-04-22 FY trading update. The single most important point for valuation today is that the share price has already re-rated 6x from c.14p in Oct-2025 to 84p, pricing in most of the recovery — the next leg depends entirely on the new FY27-FY29 plan to be unveiled, with the business trading on roughly 9-10x FY26 EV/EBITDA.

Fair value estimate

Fair value range: 80p – 115p per share | Implied market cap £74m – £107m

Methodology: EV/EBITDA on FY27e adj EBITDA, cross-checked against DCF.

• FY26 adj EBITDA = £8.6m; new business wins of £122m plus a clean balance sheet should support mid-single-digit revenue growth and continued margin expansion in FY27. I assume FY27e adj EBITDA of £9.5-11.0m.
• Peer multiple range: 8-11x EV/EBITDA (UK IT-services / government digital peers: Kainos, Made Tech, Netcall, Softcat; AIM micro-cap discount applied).
• Mid-case EV = £10m × 9.5x = £95m, less net debt £4.2m = equity value c.£91m, or c.98p per share.
• Low case: £9.5m × 8x − £4.2m = £72m (77p). High case: £11m × 11x − £4.2m = £117m (126p).

Vs latest disclosed market cap of £78.9m, this gives an absolute upside of c.+16% at the midpoint (range −5% to +37%). Current price is at the low end of fair value — modestly undervalued, not a bargain.

Sector context

• ICB classification Technology / Technology confirmed; functionally this is an IT services / public-sector digital consultancy, closer to professional services than scalable software.
• Quality, growth and leverage profile all in line with small-cap UK public-sector IT services. Lower gross margin (31.7%) than software-rich peers, but cleaner balance sheet than many AIM-listed services companies.
• Closest listed peers: Kainos Group (KNOS), Made Tech (MTEC), Netcall (NET), and more loosely Capita on the big-ticket end. Private peer set includes Nortal, BJSS, Scott Logic.

Investment thesis

1. Turnaround complete and operational discipline is now proven. Adj EBITDA margin lifted from 5.5% (FY24) to 7.3% (FY25) to 11.0% (FY26), with net debt cut 50% and leverage down to 0.5x 2026-04-22 FY trading update. The company has credibility it did not have 18 months ago.
2. Order book momentum has returned post-Spending Review. £122m of new business wins in FY26 including DEFRA (£39m), NHS England (£22m, extendable to £33m), HMLR uplift (£11m) and HMPPS (£9m) underpin FY27 revenue growth after FY26's flat line 2026-02-24 Q3 trading update.
3. Clean balance sheet and new RCF create optionality. Net debt £4.2m on a £11m RCF + £5.5m accordion + £4m overdraft, with covenants comfortably passed 2025-12-02 interim results. The business can self-fund the next strategic plan without dilution risk.

Key risks

1. UK Central Government concentration (~65% of revenue) is a single-customer-type risk. FY25 showed how a change of government and in-year spending controls can wipe 8-10% off revenue overnight 2025-02-06 Q3 trading update revision. This is structural.
2. Low gross margin for a "technology-enabled services" business. 31.7% gross margin reflects a services/body-shop economic model — a 1% utilisation drop or an election-triggered procurement freeze flows almost directly through to EBITDA (as it did in FY25) 2024-11-28 interim results.
3. AI positioning is more marketing than monetised revenue line. The filings describe TPX as "AI practitioners" but do not disclose an AI-driven revenue line, pricing uplift or margin benefit; AI is referenced as a capability sold into clients rather than captured 2025-12-02 interim results.

Operating leverage

TPX has modest operating leverage, not the "pure software" variety. Cost of sales is c.68% of revenue (people-cost dominated) and the central cost base is comparatively lean (admin ex-adjustments ~£9m p.a.). The FY25→FY26 experience is instructive: revenue up ~1% while adj EBITDA grew 54%, suggesting most incremental revenue dropped at close to 40-50% contribution margin once utilisation is well-managed. Where management targets 10-15% top-line growth under the new plan (previous guidance), an EBITDA margin reaching 13-14% is plausible — i.e. a 15% revenue beat would plausibly add c.30-40% to operating profit, not multiples. Fixed costs (central admin, premises, systems) are modest; the real swing factor is utilisation of permanent FTEs vs reliance on contractors 2024-11-28 interim results; 2026-04-22 FY trading update.

Value-trap signals

• Historical goodwill impairments (£14.5m in FY24, £5.6m H1-FY24, £4.5m FY25) suggest earlier acquisitions were overpaid for.
• Chronic reported losses even as adjusted EBITDA grows — reported loss per share was (10.1)p in FY25.
• Share-based payment charges of £1.4m p.a. and recurring "restructuring and transformation" costs that are "exceptional" every year.
• Customer concentration in UK Central Government; vulnerability to spending reviews.
• Pence of statutory profit per share remains elusive even post-turnaround.

Not a terminal value trap, but these signals warrant discount vs peer multiples.

Earnings vs. expectations

• FY24 (May-2024): Trading update confirmed revenue c.£84m, in middle of £5-6% margin guidance → met.
• H1 FY25 (Nov-2024): Revenue −9.2%, Adj EBITDA £2.3m (margin 6.1%) — in line with Oct-24 downward revision → met revised.
• Q3 FY25 (Feb-2025): Revised FY25 revenue guidance down 8-10% vs original flat target → miss.
• FY25 (May-2025): Adj EBITDA at top of 1-2% margin growth guidance; revenue in line → met revised.
• H1 FY26 (Dec-2025): Adj EBITDA £3.2m vs £2.3m prior year, in line → met.
• Q3 FY26 (Feb-2026): Upgraded EBITDA guidance to ≥£7m (from £6-7m).
• FY26 (Apr-2026): Revenue £78.1m vs consensus £76.2m; Adj EBITDA £8.6m vs consensus £7.1m → material beat.

Pattern: One major miss (FY25, driven by UK election/Spending Review disruption), followed by consistent in-line to beat-consensus delivery through FY26. Management credibility rebuilt but short track record of beats.

Conviction

Conviction: 3 (moderate).

Anchoring factors: (i) clean, well-disclosed financials with a transparent reconciliation to adjusted measures; (ii) demonstrated FY26 beat validates the turnaround narrative; (iii) peer-multiple approach is appropriate for a UK services business of this size.

Limiting factors: (i) the next three-year plan has not yet been published, so FY27-FY29 trajectory is a judgement call; (ii) the business is a professional-services firm with inherent earnings variability driven by the UK Central Government procurement cycle.
