A record year with a caveat

SRT Marine Systems (LSE:SRT) published audited results for the year to 30 June 2026 on 9 November, and the headline numbers confirmed the growth flagged in July. Revenue rose 46% to £114.1m and profit before tax increased 653% to £10.7m, giving Basic Earnings Per Share of 4.29p.

The same statement, however, records that the auditors identified a material uncertainty relating to going concern. For a company reporting its largest order book, that combination needs explaining.

About the company

SRT Marine Systems supplies maritime surveillance and domain awareness systems to national governments. Its products include tracking and communications technology used to monitor vessels and coastal waters. Projects are large and take time, with payments linked to milestones.

What the uncertainty relates to

The company attributes the uncertainty to two factors: possible mismatches in timing between receipts from customers and payments to suppliers, and near-term repayments of Loan notes. In other words, the issue identified is cash timing rather than any shortage of demand.

SRT sells large maritime surveillance and domain awareness systems to national governments. Such projects typically require a supplier to buy equipment and commit engineering resources before reaching milestone payments, and government payments can slip for administrative or political reasons. When several big projects run at once, the gap between money out and money in can widen even as profits rise.

A material uncertainty paragraph is commonly included alongside an otherwise unmodified audit opinion; it signals that the outcome depends on events that are not wholly within management's control.

Cash and contracts

The cash figures show both progress and constraint. Net cash generated from operations was £37.7m, against £1.0m a year earlier. Year-end cash stood at £57.1m, of which £27.4m was restricted, typically meaning it is tied to specific contracts or guarantees. That leaves about £29.7m freely available. The year also included the £17.5m share issue completed in April.

Commercially, LSE:SRT converted £218.4m of system contracts during the year, lifting the contracted order book to £539.5m, and said its validated prospect pipeline had grown to £2.4bn. R&D spending also increased, to £5.0m.

Why it matters

The order book underpins revenue visibility, but each new contract can initially absorb cash. If LSE:SRT continues to win work at this pace, it may need further facilities, customer advances, guarantees or new shares to bridge the timing gap. Shareholders already absorbed dilution in April, so the mix of future funding is relevant to them. The company had not announced any new Facility alongside the results.

There is a more positive reading too. Operating cash generation of £37.7m shows that milestone payments are arriving at scale, and the year-end cash position was firmer than a year earlier. The question raised by the auditors concerns the pattern of flows over the coming months rather than the underlying profitability of the contracts.

Risks and limitations

Concentration on a small number of sovereign customers means a single delayed payment can have an outsized effect. Political changes, procurement disputes and Supply chain disruption, which affected margins on one project last year, could all alter cash flows.

The results in numbers

Revenue of £114.1m, up 46%, implies prior-year revenue of about £78.2m. Profit before tax of £10.7m, up 653%, implies about £1.4m a year before, so the Business moved from a small profit to a substantial one. Profit before tax of £10.7m on revenue of £114.1m is a Margin of about 9.4%. Net cash from operations of £37.7m against £1.0m shows the improvement in cash generation, though the going-concern note highlights timing.

What the going-concern uncertainty means

Auditors report a material uncertainty when events or conditions may cast significant doubt on the company's ability to continue as a going concern, and the company has disclosed them adequately. It does not mean the company is insolvent, and the audit opinion can still be unmodified. The two causes given, timing of receipts and payments, and near-term repayments of loan notes, point to Liquidity management. Cash of £57.1m includes £27.4m restricted, so free cash of about £29.7m is available for general purposes.

Order book and pipeline

Contracts of £218.4m converted in the year, and the order book of £539.5m is about 4.7 times annual revenue. A validated pipeline of £2.4bn is about 4.4 times the order book. The pipeline is a measure of potential, and conversion is uncertain. A large order book provides visibility but also implies large purchases of equipment ahead of payments, which is the cash-timing pressure.

Investment and funding

The £17.5m share issue completed in April added cash during the year. R&D spending of £5.0m is about 4.4% of revenue. The loan note repayments mentioned as a Factor are scheduled, so the company will need cash or refinancing to meet them. Management's ability to match customer receipts to supplier payments is central to the auditors' conclusion.

Contract structure and working capital

Large government systems are usually delivered under contracts that pay in stages, with the supplier funding equipment purchases and engineering effort in advance. The gap between those outflows and the milestone receipts is the Working Capital need. When several large contracts are in progress at once, the need can be large even if each contract is profitable.

The company has £27.4m of restricted cash, which may be tied to guarantees given to customers. This is normal in contracts of this type, but it means that the free cash is smaller than the headline balance.

The loan notes due for repayment add a fixed obligation to the picture. If receipts from customers arrive on time, the company can meet those payments from operating cash flow, which is why the auditors drew attention to timing.

The year's results, with revenue up 46% and profit before tax up 653%, show the business moving from a long period of heavy Investment towards profitable delivery. The pipeline of £2.4bn indicates the potential for further orders, but each win must be funded and delivered.

What comes next

Management hosted a results webcast on 10 November. The Annual General Meeting is scheduled for 16 December at 11am at the company's Midsomer Norton offices, preceded by an investor open day from 9am. Investors will look there, and in subsequent contract announcements, for evidence of milestone receipts, progress on refinancing the loan notes and conversion of the £2.4bn pipeline into signed contracts with clear payment schedules. The interim period to 31 December will be the first test of whether the cash gap is narrowing.
