The question in focus

Cohort's largest single order disclosed so far in its current financial year is a €140.7 million contract won by its German Subsidiary ELAC SONAR, announced on 14 August 2026, and the September AGM statement said more about the order book that followed.

In short, the Polish order strengthens multi-year visibility rather than transforming near-term earnings. Deliveries are scheduled to run into the mid-2030s, so Revenue from it should be spread across roughly a decade, while the board has kept its existing expectations for the year to April 2027 unchanged.

About the company

Cohort is a Holding Company for defence technology businesses based near Reading. Its subsidiaries are grouped into two areas: communications and intelligence, and sensors and effectors. ELAC SONAR, based in Germany, sits in the second group and designs sonar systems for naval vessels, including submarines. Other group companies Supply electronic warfare, communications and engineering services to defence customers, with a significant share of work coming from the UK Ministry of Defence and allied navies.

Defence suppliers typically work on long programmes, which gives them visibility but also ties results to government budgets, procurement timetables and delivery milestones.

What ELAC has agreed to supply

According to the 14 August announcement, ELAC will provide integrated sonar systems for Poland's Orka submarine programme, working with Saab, which the release describes as a partner on the programme. Work began immediately. Chief executive Andy Thomis said the order confirmed ELAC's standing as a provider of advanced digital sonar and described the collaboration with Saab as important.

LSE:CHRT said the contract, together with other recent wins, should enhance adjusted Earnings per share in the following financial year and beyond. It did not publish a revenue phasing schedule, Margin assumption or currency hedging detail, so the precise annual contribution cannot be calculated from public disclosures.

How the order book has moved

Cohort's final results for the year ended 30 April 2026 reported revenue of £306.4 million, up 13%, adjusted operating profit of £36.3 million, up 32%, and adjusted Earnings Per Share of 61.9p. Order intake was £314.2 million and the closing order book a record £618.8 million. A final Dividend of 12.10p was proposed, 10% higher, and the bank Facility was renewed and expanded to £175 million.

By the AGM on 24 September, LSE:CHRT said the order book stood at about £700 million in mid-September, covering close to 90% of expected FY27 revenue. The rise of roughly £80 million since April is broadly consistent with the euro-denominated Orka award being booked alongside continuing deliveries, although the company has not supplied a bridge between the two figures.

Why the contract matters

Cohort (LSE:CHRT), based near Reading, is a holding company for defence technology businesses split between communications and intelligence, and sensors and effectors; ELAC sits in the latter. Naval sonar is among its most export-orientated activities, and a long-dated programme with a major European prime contractor gives the German Business a durable workload as Baltic and NATO navies increase spending.

High revenue cover matters because the board has said FY27 performance will be weighted towards the second half. A large share of the year's revenue already being under contract reduces reliance on new orders landing late in the period, though it does not remove execution risk.

Risks and limitations

Long submarine programmes can be rescheduled by governments or prime contractors, and slippage would push revenue to later years. Fixed-price engineering work carries cost-overrun risk, while euro income translated into sterling introduces currency sensitivity. A second-half-weighted year also leaves less room for delivery delays before April.

Interpreting the order and the order book

The €140.7m order is large in relation to the group's annual revenue of £306.4m, equal to roughly half of a year's revenue at current exchange rates, but because deliveries run into the mid-2030s the annual contribution is expected to be much smaller. If it were spread evenly over ten years, the average would be about €14m a year, a modest addition to group revenue. Its value lies in the length of the programme, which supports the workload at ELAC over a long period.

The record closing order book of £618.8m at 30 April and about £700m in mid-September, covering close to 90% of FY27 revenue, show how much of the year's revenue is already contracted. High cover reduces dependence on new orders in the second half, when the group expects its revenue to be concentrated.

The financial base

Revenue of £306.4m, up 13%, and adjusted operating profit of £36.3m, up 32%, indicate improving operating margins, which rose to roughly 11.8% from about 10.1% a year earlier. Adjusted earnings per share of 61.9p and a final dividend of 12.10p, up 10%, round out a year of growth. The expanded £175m bank facility provides funding capacity for Working Capital and acquisitions, while the company has said the contract and other recent wins should enhance adjusted earnings per share in the following year.

Watching the programme risk

Naval programmes can be rescheduled by governments or prime contractors, and the company works with Saab on Orka, so the timetable depends on the programme as a whole. Fixed-price engineering contracts expose a supplier to cost overruns, and euro revenues translate into sterling at changing rates. The interim report for the six months to 31 October 2026 is the next checkpoint, and it should show how much of the Orka work is starting to contribute.

Defence contracts and timing

Defence orders are often large and are delivered over several years, so the revenue they produce is spread across many reporting periods. The date of an award therefore says little about when the revenue will be recognised, which depends on delivery milestones and customer acceptance.

A large order also affects the order book, which is a measure of work contracted but not yet delivered. A larger order book supports visibility for future years, although the conversion of orders into revenue and profit depends on the company delivering on time and on budget.

What to watch next

The next scheduled checkpoint is the interim report for the six months to 31 October 2026. That release should show how much Orka work has started to flow through revenue, whether the order book has held near £700 million and whether management still expects the year's outcome to meet its existing view.
