LON:CER - Cerillion PLC
Executive Summary
Cerillion PLC is a London-listed supplier of billing, charging, revenue management and customer relationship management software for telecoms operators and utility companies, with a pre-paid and post-paid BSS suite deployed across the UK, Europe, the Middle East and the Americas. The company is a long-standing specialist in its niche, competing principally against larger BSS vendors by offering a more modular, lower-total-cost-of-ownership platform.
The investment case rests on hard contract momentum - most visibly the Omantel engagement and the Armenian upsell, both flagged in the H1 trading update - translating into a record order book that supports H2 licence revenue recognition, dividend growth, and continued European expansion. The principal near-term catalyst is the H1 2026 results print and the management commentary on H2 licence timing, which will determine whether the order intake converts into reported revenue on schedule. The main risk is that licence revenue slips into a later period, that peers with deeper pipelines outperform on contract announcements, or that the absence of imminent M&A limits re-rating catalysts.
BUY. Conviction Score: 65/100. The view would shift to a more cautious stance if H1 2026 results show a material revenue slip versus management guidance of roughly GBP 18.0m and EBITDA of about GBP 6.2m, or if a named contract loss is disclosed in the interims.
Thesis break: A material H1 2026 revenue or EBITDA miss versus management guidance, or the disclosed loss of a named contract such as Omantel or the Armenian upsell customer, would invalidate the thesis regardless of price.
Business Model
Cerillion generates revenue from licences, subscription and support fees, and professional services delivered against its BSS platform, which covers pre-paid and post-paid billing, rating and charging, CRM, and analytics for telecoms and utility operators. The product is sold both as an outright perpetual licence with associated implementation services and, increasingly, on a subscription basis, which produces a recurring revenue stream that underpins forward visibility. Implementation and professional services contribute the lumpiest element of revenue and tend to skew the timing of recognition between reporting periods.
The customer base is concentrated in telecom operators and, to a lesser extent, utility companies, with notable contract wins including Omantel in the Middle East and an upsell into an Armenian customer, both of which were highlighted in the H1 2026 trading update. New orders doubled to GBP 39.6m as at 30 March 2026 versus GBP 19.6m a year earlier, providing hard evidence of demand momentum and reinforcing the order book that supports H2 licence revenue. The competitive moat rests on deep domain specialisation in telecoms billing, a track record of multi-year deployments, and the high switching cost once a BSS platform is integrated into a customer's rating, charging and customer management workflows.
Management expects H1 2026 revenue of approximately GBP 18.0m and EBITDA of about GBP 6.2m, with the full-year performance weighted to the second half on the back of the elevated order book. Dividend growth has been referenced by sell-side coverage as a supporting element of the cash-generative profile. The recurring share of revenue is not disclosed at a granular level in the research data, but the subscription component of the platform is identified as a structural tailwind to revenue quality.

Thesis Evaluation
Bull Case (33% weight)
New orders of GBP 39.6m convert into H2 2026 licence revenue ahead of plan, dividend growth continues, and Cerillion announces either a follow-on upsell with the Armenian customer or a new contract win, prompting a re-rating. Analyst price targets have moved from GBP 12.49 to GBP 15.23 over five quarters per third-party trackers, supporting an upside scenario. Bull case 12-month target of 1450p.
Base Case (48% weight)
The H1 2026 results print lands close to guidance of GBP 18.0m revenue and GBP 6.2m EBITDA, the order book converts as scheduled into H2 licence revenue, and dividend growth is maintained at recent pace, with sell-side targets drifting modestly higher. The P/E of roughly 20x does not appear stretched against the growth profile but offers limited surprise absent fresh catalysts. Base case 12-month target of 1180p.
Bear Case (19% weight)
Licence revenue slips into a later reporting period, peer BSS vendors secure larger reference wins, and the absence of M&A or fresh named catalysts caps re-rating potential. P/E compression to the high-teens is plausible in a softer sector tape, exposing the stock to a material drawdown from current levels. Bear case 12-month target of 700p.
Key Risks
- Licence Revenue Timing Slippage: H1 2026 results show revenue or EBITDA materially below guidance of GBP 18.0m and GBP 6.2m, deferring licence recognition into later periods and weighing on the order-to-revenue conversion story. Estimated probability: 30%. Impact: moderate.
- Peer Outperformance on Named Contracts: Larger BSS competitors secure higher-profile telecom reference wins, drawing investor mind-share away from Cerillion despite its own order momentum and limiting multiple expansion. Estimated probability: 25%. Impact: moderate.
- Small-Cap Liquidity and AIM Register Constraints: Limited free float and AIM-listing dynamics restrict institutional accumulation, increasing share-price volatility around results and risking a discount to intrinsic value. Estimated probability: 35%. Impact: moderate.
- Absence of M&A or New Named Catalysts: With no imminent acquisition or major new contract announcements in the pipeline, the share price lacks a fresh re-rating trigger and may trade sideways even if H1 results are in line. Estimated probability: 40%. Impact: low.
- CFO Transition Execution Risk: Greg Price is expected to join no later than 1 May 2026; any delay in regulatory clearance or a weak first reporting cycle under the new CFO could unsettle the financial narrative. Estimated probability: 15%. Impact: low.
Who Should Own It / Avoid It
Ideal for: UK small-cap and specialist software investors with a tolerance for AIM-listed volatility and a minimum holding period of 12 to 18 months. Suits investors looking for exposure to recurring revenue dynamics in telecom and utility billing, who can underwrite a single-name position against the risk of licence revenue slippage between reporting periods.
Avoid if: Investors requiring deep liquidity, those unable to tolerate a sub-GBP 200m market-cap register, or anyone benchmarking exclusively against large-cap US software peers where Cerillion's P/E and growth rate profile would appear less compelling. The name is also unsuitable for investors with a strict requirement for near-term dividend yield or for mandates that exclude AIM-listed equities.
Recommendation
BUY - 65/100. The recommendation reflects a constructive view on the order book, the Omantel-led new order doubling to GBP 39.6m, and management's clear visibility into H2 2026 revenue, partially offset by the absence of imminent M&A and the risk of licence revenue slippage. An upgrade to a higher tier would require a clean H1 print in line with or ahead of guidance plus a fresh named contract catalyst, or a credible M&A announcement. A downgrade would follow a material miss against the GBP 18.0m revenue and GBP 6.2m EBITDA guide, a disclosed loss of a named customer, or sustained peer outperformance on contract wins. At the current price of 930.00p the shares trade above our buy ceiling of 860.00p: the thesis is credible but the price is not - new positions only below that level.
The probability-weighted value across our three scenarios is 1177.90p, 27% above the current price of 930.00p - the market has not yet priced our probability-weighted view. Levels below are derived from the scenario targets and probabilities above, not from percentage offsets to today's price.
below 860.00p - below this level the upside to the base-case target (1180.00p) is at least 2x the downside to the bear case (700.00p), the minimum risk/reward we require before committing new capital.
between 860.00p and 1180.00p - 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 1180.00p - 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 33%.
if A material H1 2026 revenue or EBITDA miss versus management guidance, or the disclosed loss of a named contract such as Omantel or the Armenian upsell customer, would invalidate the thesis regardless of price, regardless of price - the bear target of 700.00p is the backstop, not an arbitrary percentage stop.
