Helix Exploration PLC (HEX) — Investment Research Note
Executive summary
Helix is a UK-listed, US-focused helium micro-cap that in February 2026 became Montana's first commercial helium producer at its Rudyard field and, in July 2026, acquired the Keyes helium liquefaction complex in Oklahoma for US$11m to become a vertically integrated independent helium producer. Across the five-year window the company has moved from pre-IPO (April 2024) to first production (Feb 2026), first spot offtake (May 2026) and integrated producer-liquefier (July 2026), funded by a succession of equity placings (totalling >£22m since IPO) and recurring losses (FY25 loss £1.86m; H1 FY26 loss £0.77m). The single most important valuation point is that near-term fair value is overwhelmingly a function of the un-proven Rudyard cash-flow ramp and the quality of the Keyes earnings stream — neither of which is yet in audited group accounts.
Fair value estimate
Methodology: sum-of-the-parts NAV (asset-based), triangulated against a lightly risk-adjusted earnings capitalisation of the two production hubs. A DCF is not reliable at this stage because fewer than six months of production exists.
| Component | Approach | GBP (m) |
|---|---|---|
| Keyes complex (Oklahoma) | US$3.4m annualised EBITDA (US$1.42m × 12/5) × 6–8x, less $1m escrow ≈ £15–20m | 15 – 20 |
| Rudyard (Montana) | Mgmt guidance $15–25m peak post-tax profit; probability-weighted NPV8 at 50% confidence ≈ US$30–60m | 22 – 45 |
| Treasure State Drilling rig | At recent transaction value US$0.6m | 0.5 |
| Net cash post July raise | £16m placing + £1.6m retail less US$12m Keyes cash cost ≈ £6–8m | 6 – 8 |
| Equity value | £44 – 74m | |
| Per-share (280.6m shares) | 16p – 26p |
A bull case (helium spot prices sustain 33–50% YoY uplift mentioned in the 2 July 2026 placing announcement, both hubs run flat-out) gets to roughly £100–120m / 36–43p. A bear case (slower well tie-ins, lower helium realisations, dilution to fund further drilling) is c.£30m / 11p.
Fair value range: 16p – 36p per share; implied market cap £45m – £101m. Current: 29p / £81.4m. Absolute upside at the midpoint (26p) ≈ −10% — i.e. close to fair, modestly to the full side.
Sector context
Confirmed classification: Energy (industrial-gas / helium sub-sector within upstream resources). Helix sits well below the typical Energy peer in scale, consistency of disclosure and balance-sheet strength; it is more a junior exploration-and-development listing than a conventional energy producer. Closest listed comparables are Pulsar Helium (TSXV: PLSR), Blue Star Helium (ASX: BNL) and the larger, cash-generative Air Liquide / Linde / Air Products (these are not comparables for valuation but set the floor for helium end-market pricing).
Investment thesis (bull case at the current price)
- Transition from explorer to vertically-integrated producer is largely complete and funded. First production (23 Feb 2026), first spot offtake (May 2026), rig acquisition (June 2026) and Keyes liquefaction completion (13 July 2026) have all occurred in a 5-month window, with cash topped up by a £16m placing at 22p 2026-07-02 Acquisition/Placing; 2026-07-13 Completion.
- Favourable helium backdrop. Management cites spot helium prices up ~33% YoY, periodic spikes >50%, and the structural decline of the BLM Cliffside/Hugoton system — plus a reference to Iran/Qatar disruption described as "Helium Shortage 5.0" 2026-03-26 Annual Report; 2026-07-02 Placing. If prices hold, Rudyard's unit economics (pricing was "materially ahead of pre-IPO assumptions" per 30 June 2026 interim) convert directly to margin.
- Keyes acquired at a stated 65% discount to US$31m replacement cost, with US$2.91m revenue / US$1.42m EBITDA already demonstrated for the 5 months to 31 May 2026 2026-07-02 Acquisition. If reproducible, that is a c.3.2x trailing EV/EBITDA entry price on a scarce (one of six US liquefaction facilities) asset.
Key risks
- Serial dilution and short operating history. Share count has grown from 22.7m (Mar 2024) to c.280m post-July 2026 placing, with retained losses of £4.8m at Mar 2026 and no reported group revenue in H1 FY26 2026-06-30 Half-year. The AGM pricing of options on Drachs' nominees (strike £0.10–£0.22 vesting on share-price hurdles) signals further equity creep 2026-07-03 Result of Placing.
- Single-asset, single-commodity, early-stage execution. With three wells currently flowing and a fourth connecting, membrane throughput cap is already an issue (US$0.5m membrane upgrade earmarked in July use-of-proceeds). Any well under-performance, PSA/membrane downtime or offtake renegotiation would materially re-rate the stock 2026-07-02 Placing use of proceeds.
- Keyes diligence and integration risk. The US$2.91m / US$1.42m revenue/EBITDA figures are unaudited, 5-month, and come with a US$1m escrow and a US$1.6m working-capital adjustment 2026-07-02 SPA terms. A standard warranty/indemnity shortfall or a tolling customer loss would halve the implied Keyes contribution.
Operating leverage
Helium production is moderately high operating leverage in principle but with a very small denominator at Helix today. The group P&L shows administrative + operational costs of £0.78m against zero revenue in H1 FY26 (vs £0.52m prior H1); fixed-cost infrastructure (£5.5m PP&E in buildings/gathering/PSA plant) is largely in place at Rudyard, so each incremental Mcf of helium flows through at near-wellhead gross-margin minus modest variable processing cost. Management's own framing — "pre-tax cashflow of circa US$4m per well per year" at Rudyard, with four wells online at full membrane capacity, and projected "peak sustained post-tax profit of US$15–25m per year" — implies a step-change relative to today's cost base of £1–2m per annum. Keyes adds a different lever: the plant has material spare capacity for third-party tolling, which converts fixed-cost coverage into pure margin on each incremental Mcf tolled. If helium spot pricing stays elevated and both hubs run near design capacity, a 10–20% revenue beat vs today's run-rate could easily more than double group operating profit from a low base; but note this is leverage off a tiny base, not leverage off a mature P&L. 2026-06-30 H1; 2026-07-02 Placing; 2026-03-26 Annual Report.
Value-trap signals
- Recurring equity dilution with no cash-flow history (five placings/subscriptions since IPO).
- A related-party placing: largest shareholder Drachs subscribed £7m of the £16m July placing and acquired board appointment rights plus performance options, declared an AIM Rule 13 related-party transaction 2026-07-03 Result of Placing.
- Auditor flagged a "material uncertainty relating to going concern" in the FY24 Annual Report 2025-02-17 Annual Report, Note 2.2.
- Single-commodity, single-geography-cluster exposure with no hedging policy disclosed.
Earnings vs. expectations
Because Helix has reported no revenue in any audited period yet, there is no earnings-beat/miss history to assess. Operationally, management has broadly delivered on milestones it set at IPO: Rudyard first production slipped from "Q4 2025" (June 2024 Interim) to "Q2 2025" (Feb 2025 Annual) and ultimately landed at 23 Feb 2026 — a slip of 3–6 months. Scoping-study NPVs have been revised upwards (Ingomar NPV8 of US$303m in June 2024 vs. Rudyard net revenue of US$115–220m over 12.5-year life stated repeatedly from Mar 2025 onward). Pattern: timelines slip modestly, resource/NPV figures are revised up; no visible analyst-consensus pattern because no consensus EPS line exists.
Conviction
Conviction: 2 (low). Anchors: (i) a concrete acquisition price and 5-month EBITDA readout for Keyes anchor one asset; (ii) replacement-cost benchmarking for Keyes gives a defensible floor; (iii) the July 2026 placing at 22p provides a very recent market-cleared print for the whole business. Limits: (i) less than six months of helium production and no audited group revenue — the Rudyard half of the SOTP is almost entirely forward-looking; (ii) helium pricing is opaque with no deep spot market, so EBITDA and NPV conclusions are highly sensitive to realised prices that even management admits are not transparently quoted.
Driver scoring summary (0–100)
ai_beneficiary28 — helium is a semiconductor-manufacturing input, so there is a tangential tie to the AI buildout, but Helix is a sub-scale commodity producer with no pricing power over the AI value chain; the AI mention in filings is downstream-demand colour, not revenue capture.operating_leverage62 — fixed-cost upstream infrastructure plus Keyes's spare tolling capacity; genuine leverage, but on a tiny base and highly sensitive to realised helium pricing.earnings_surprise_trend50 — no earnings history to judge; this is a "not enough data" 50.cyclicality70 — single-commodity producer in a market with documented multi-cycle supply shocks.moat35 — scarcity of US liquefaction capacity (one of six) is a modest structural edge; otherwise commodity economics.leverage22 — net cash post-July raise, no bank debt disclosed.earnings_quality40 — zero revenue in H1 FY26, prior auditor going-concern caveat, and reliance on unaudited 5-month Keyes figures.management_quality48 — delivered first production and executed Keyes at a stated large discount, but heavy use of related-party placings and performance-option issuance.growth_momentum70 — from zero to producer-plus-liquefier in 18 months; direction is clearly up, albeit from a very low base.overall_score290 — thin, indirect AI linkage; valuation close to or slightly above a defensible central NAV; genuine operating leverage but on a sub-scale and fragile base. Not a fit for the investor's "AI-receiver + fair price + durable downside protection" strategy.
