LON:CER - Cerillion PLC
Executive Summary
Cerillion PLC is a London-listed provider of billing, charging and customer relationship management software, with a focus on communications and media organisations; the supplied research does not provide a defensible market-share figure, so its precise market position remains unconfirmed.
The investment case requires order momentum to convert into revenue and EBITDA, while the next material checkpoint is the full-year FY2026 result, whose timing has not been confirmed in the supplied material; the primary risk is that contract timing and margin pressure leave earnings materially below expectations and no identifiable near-term catalyst supports a re-rating.
OPPORTUNISTIC BUY. Conviction Score: 55/100. The view would change if FY2026 results confirm the earnings and margin shortfall indicated by the research, or if a recovery in order intake and earnings visibility emerges without further guidance reductions.
Thesis break: A further reduction in FY2026 revenue or EBITDA guidance, delayed recognition of the order book, the loss of the Omantel contract or another material contract, or a dilutive equity raise would invalidate the investment thesis regardless of price.
Business Model
Cerillion generates revenue by supplying billing, charging and customer relationship management software solutions to communications and media organisations. The supplied material indicates that contract timing is central to the financial profile: new orders doubled to GBP 39.6m by 30 March 2026 from GBP 19.6m in the first half of 2025, principally because of the Omantel contract.
Revenue recognition depends on the delivery and acceptance of contracts, making order intake an important indicator of future revenue rather than immediate recognised sales. The research cited an expected first-half revenue of about GBP 18.0m and EBITDA of GBP 6.2m, implying a first-half EBITDA margin of approximately 34%, although this figure comes from an interview rather than a primary results announcement and should be treated as unconfirmed.
The competitive moat is not quantified in the available evidence. Cerillion's specialist billing and charging software, domain expertise and customer relationships may support switching costs, but the supplied material does not provide retention rates, recurring-revenue disclosure, customer concentration, market share or comparative margin data. The principal business-model dynamic is therefore the conversion of a rising order book into recognised revenue and sustainable EBITDA while avoiding the margin pressure identified in the research.

Thesis Evaluation
Bull Case (23% weight)
New orders of GBP 39.6m at 30 March 2026 convert into recognised revenue as expected, FY2026 guidance stabilises and the new Chief Financial Officer improves financial delivery. If earnings recover and contract momentum becomes visible through subsequent results, the shares could reach 950p within 12 months.
Base Case (47% weight)
The order book supports some recovery, but conversion delays and margin pressure prevent a full re-rating, while FY2026 earnings remain below the previously expected trajectory. The most likely 12-month valuation is 760p, modestly above the current 710p price but consistent with an OPPORTUNISTIC BUY and a conviction score of 55/100.
Bear Case (30% weight)
Contract timing slips further, margin pressure persists and no material new contract offsets the earnings shortfall identified in the April 2026 trading update. If the market concludes that the 15.29 price-to-earnings multiple is unsupported by near-term earnings delivery, the shares could fall to 500p within 12 months.
Key Risks
- Revenue conversion and contract timing: Order intake may not convert into recognised revenue on the expected timetable, leaving FY2026 revenue below the prior outlook. Estimated probability: 45%. Impact: severe.
- Margin pressure: The research identifies weaker margin guidance, increasing the risk that cost growth or delayed delivery prevents improvement in EBITDA conversion. Estimated probability: 40%. Impact: severe.
- Absence of near-term catalysts: The supplied research identifies no firm contract win, acquisition or other hard catalyst capable of offsetting the earnings downgrade. Estimated probability: 50%. Impact: moderate.
- Earnings downgrade and valuation risk: Further guidance reductions could undermine the stated 15.29 price-to-earnings valuation and trigger a further de-rating. Estimated probability: 35%. Impact: severe.
- Customer and contract concentration: The reported doubling of orders was driven principally by the Omantel contract, creating concentration risk if deployment is delayed or the associated revenue is lower than expected. Estimated probability: 30%. Impact: moderate.
- Execution through financial leadership change: Greg Price became Chief Financial Officer on 1 May 2026, adding transition and execution risk during a period of weaker guidance. Estimated probability: 25%. Impact: moderate.
Who Should Own It / Avoid It
Ideal for: investors who accept company-specific execution risk and can tolerate a wide range between the 500p bear target and the 950p bull target over a minimum 12-month holding period; the position is appropriate only for investors able to monitor results, guidance and order conversion closely.
Avoid if: investors require recurring revenue visibility, dividend income, low volatility or a high degree of balance-sheet confidence, because the April 2026 earnings downgrade, margin pressure and absence of a firm near-term catalyst leave the outcome unusually dependent on management delivery.
Recommendation
OPPORTUNISTIC BUY - 55/100. The tier reflects a credible recovery case supported by GBP 39.6m of new orders at 30 March 2026, but also a clear earnings and margin setback that keeps conviction below a high-conviction rating. The call would upgrade if subsequent results demonstrate order conversion, stable guidance and evidence that margin pressure is easing. It would degrade if further guidance reductions, delayed contract revenue or the loss of a material contract undermine cash earnings visibility. At the current price of 905.10p the shares trade at or above our base-case target of 760.00p: the base case is fully priced, existing holders should consider trimming, and new positions are not advised above 586.67p.
The probability-weighted value across our three scenarios is 725.70p, 20% below the current price of 905.10p - the market is currently pricing the shares ahead of our probability-weighted view. Levels below are derived from the scenario targets and probabilities above, not from percentage offsets to today's price.
below 586.67p - below this level the upside to the base-case target (760.00p) is at least 2x the downside to the bear case (500.00p), the minimum risk/reward we require before committing new capital.
between 586.67p and 760.00p - the base case is not yet fully priced, so existing holders are paid to wait, but new money gets no margin of safety in this zone.
above 760.00p - at this level the base case is fully reflected in the price and anything beyond it is paying for a bull scenario we weight at 23%.
if A further reduction in FY2026 revenue or EBITDA guidance, delayed recognition of the order book, the loss of the Omantel contract or another material contract, or a dilutive equity raise would invalidate the investment thesis regardless of price, regardless of price - the bear target of 500.00p is the backstop, not an arbitrary percentage stop.
