Chairman's Statement

The first half of the financial year has been very busy with much progress made across both our systems and transceivers businesses. With systems contracts worth £160m to deliver, our project teams have been working closely with the relevant customers and third-party suppliers on the substantial preparatory and planning work required for their delivery, with multiple milestones scheduled for H2, several of which are substantial revenue generating milestones. Alongside this our transceivers business has made good progress growing its sales and distribution as well as launching new products which we expect to sell well during H2.

As already reported in our October 2023 trading statement, during the H1 period ending 30th September 2023, our systems business did not generate any revenues having not completed any revenue milestones and as such the £5.5m of Group revenues we are reporting derives entirely from our transceivers business. Gross profit was 37%, resulting in a loss for the period of £4.6m, and a period end cash position of £3.9m.

Systems

Our systems business, which provides maritime surveillance and monitoring systems for government agencies such as coast guards and fisheries, has made good progress on existing, new and prospective contracts. Our existing contract with BFAR in the Philippines is in its final completion stage and is expected to be completed during the second half. Having completed the first phase of our £40m Middle East Border Agency project, we have been working closely with the customer to aggregate and plan the next two phases into a single phased implementation which we expect to commence during Q4 of this financial year. This work has included significant project planning as well as preparation and staging of equipment ready to make the first invoice and payment generating deliveries upon instruction to proceed from the customer.

Much planning work has also been completed in respect of our $180m (£145m) contract with a SE Asia National Coast Guard (as announced on 18 May 2023), which is expected to commence in the next few months upon completion of a government-to-government loan agreement, which is in its final formal stages. This work has included the completion of the substantial procurement planning which includes supplier selection, price and terms negotiation and detailed project planning with the customer and our local civil works contractors. This has included multiple in-country meetings as well as a recent multi-agency final project planning and review meeting in the UK with the end customer and the UK government present. We expect to commence first deliveries during Q4, which will also include the first substantial revenue milestones.

We have also been working closely with an existing long-standing Middle East Coast Guard who wishes to move on to the next stage of their maritime surveillance system strategy and expand and enhance their existing system. Following the usual period of consultations which has defined the scope of this follow-on phase we have received official notification that they are now ready to proceed and are awaiting issue of the contract, expected shortly, whereupon we shall immediately commence implementation with some deliverables potentially falling into H2 depending on the exact timing of contract and equipment procurement lead times.

In tandem with this focused work on existing customers, our sales and support teams have substantially progressed negotiations and project specification discussions with several of our validated new contract opportunities and as such we expect to see further new contracts in the near future. In general, we continue to see growing interest and engagement from nation-state agencies who desire to acquire independent maritime surveillance capabilities to transform their understanding and monitoring of their marine domains and adopt a digital intelligence lead approach to active management and law enforcement.

The SRT-MDA System has continued its development journey and has grown to be a sophisticated national scale integrated surveillance and monitoring system which can be configured for either coast guard and or fisheries users. Our development teams continue to enhance its capabilities with particular focus around its data fusion, analytics and command & control capabilities. This is a long-term continuous improvement development roadmap which is the foundation of our success and will support the long-term relationships we form with customers.

Transceivers

Our transceivers business, which develops and sells maritime navigation safety and communication transceivers, continues to grow, with revenues 5% ahead of the comparative period last year. This growth reflects the established long-term market trend of marine navigation digitisation and SRT's position as the dominant provider of AIS and related transceiver systems. We see a blend of growing regulation and market-ripple adoption driving demand, for example the Port of Antwerp has recently extended existing regulation affecting certain classes of commercial vessels to make it mandatory that all vessels operating there are required to have an AIS.

We have continued to grow our global distribution network which now consists of over 5,000 entities, from dealers and distributors for our own em-trak brand to leading original equipment manufacturers ("OEM's") located across the world from Australia, Japan to Europe and USA. Of note is our high margin Digital ATON Systems ("DAS") sub-division which is focused on providing specialist navigation devices for buoys and infrastructure. We see a substantial global opportunity and have launched new kitted products which make it easy for ports, waterways, and marine infrastructure owners to implement these systems with full interoperability with their existing systems. This is revealing new and unexpected opportunities, an example being a new opportunity whereby many thousands of fish farms in the EU will require tracking and monitoring using AtoN's from next year. We now have a dedicated salesperson focused on this growing market, and this has started to bear fruit with more sales and a growing pipeline of opportunities.

Our new NEXUS marine communication VHF/DSC radio system is now in its later stages of development and commenced its testing phase along with a soft launch to our dealers in the November METS exhibition. We have had a stronger market reaction than was expected and received forward orders for over 100 units within the first three days of the soft launch. We expect to complete all final testing and pre-production by the summer of 2024 and start shipping product in Autumn 2024. This is approximately 12 months later than we had originally planned due to a conscious decision to be cautious and undertake a much more extensive product testing and refinement period due to the complexity of the product and to ensure our first voice communications product is of a standard commensurate with what the market expects from an SRT device.

Outlook

I acknowledge and appreciate shareholders concerns regarding the financial performance imbalance between the two halves of this financial year; however, this is the nature of the timing of revenue related deliverables on our current systems projects and was expected. With the revenue milestones scheduled for the second half, we are confident of our full year performance.

Going forward, with multiple system contracts running in parallel, we expect a smoother distribution of revenues across financial periods. However, I must highlight that the exact timing of deliverables on a project are influenced by multiple factors, some of which beyond our control and thus they can easily slip either side of an accounting line. This does not detract from the fundamentals of our business which are now built on robust, proven products that deliver multiple revenue streams with defensible profit margins, being delivered by an experienced team into a global market whose growth is driven by strong fundamentals of security, safety and environment protection.

CONSOLIDATED STATEMENT OF COMPREHENSIVE INCOME

FOR THE SIX MONTHS ENDED 30 SEPTEMBER 2023

NOTES TO THE INTERIM FINANCIAL STATEMENTS

Accounting Policies

Basis of preparation

The interim financial information in this report has been prepared using accounting policies consistent with International Financial Reporting Standards (IFRS) as adopted by the United Kingdom. IFRS is subject to amendment and interpretation by the International Accounting Standards Board (IASB) and the IFRS Interpretations Committee and there is an ongoing process of review and endorsement by the UK Endorsement Board. The financial information has been prepared on the basis of IFRS that the Directors expect to be adopted by the UK Endorsement Board and applicable as at 31 March 2024.

Non-statutory accounts

Financial information contained in this document does not constitute statutory accounts within the meaning of section 434 of the Companies Act 2006 ("the Act"). The statutory accounts for the year ended 31 March 2023 have been filed with the Registrar of Companies. The report of the auditors on those statutory accounts was unqualified and did not contain a statement under section 498(2) or (3) of the Companies Act 2006. The audit report drew attention by way of emphasis to a material uncertainty relating to going concern and included an emphasis of matter paragraph in relation to the uncertainties associated with the forecasting of future revenues and profits.

The financial information for the six months ended 30 September 2023 and 30 September 2022 is unaudited. The interim financial statements will be available to download on the Company's website www.srt-marine.com from 20 November 2023.

Accounting policies

The accounting policies as applied by the Group are the same as those applied by the Group in the consolidated financial statements for the year ended 31 March 2023.

(Loss) / earnings per share

The basic (loss) / earnings per share has been calculated using the loss for the period of £4,618,680 (six months ended 30 September 2022 - profit of £2,122,712, year ended 31 March 2023 - profit of £69,520) divided by the weighted average number of ordinary shares in issue of 187,174,103 (six months ended 30 September 2022 - 180,676,939 and year ended 31 March 2023 - 180,961,021).

During the period ended 30 September 2023, the Group has incurred a loss for the period and therefore there is no impact of the share options granted on diluted earnings per share.

For the previous period ended 30 September 2022, the calculation of diluted earnings per share has been calculated on profit for the period of £2,122,712 (year ended March 31 2023 profit of £69,520). It assumes conversion of all potentially dilutive ordinary shares, all of which arise from share options. A calculation is performed to determine the number of shares to be issued for no consideration. The number of dilutive shares under option at 30 September 2022 was 1,787,866 (At March 31 2023 1,958,724) and the weighted average number of ordinary shares for the purposes of dilutive earnings per share was 182,464,805 (year to 31 March 2023 182,919,745).

Borrowings

The bank loan was drawn down in September 2023 as a short-term loan provided under the UK Government Recovery Loan Scheme (RLS) at an interest rate of 3.5% above base rate.

Other loans relate to drawdowns on a secured note programme which has been arranged by LGB Capital Markets. The loan note liabilities are secured by a floating charge over the Group's assets. The loans have terms of up to 3 years and interest rates of 8-12%.

During the current period and previous year, a covenant in relation to debt service cover was breached and a waiver from loan note holders was obtained shortly after the period/year end. Due to the waiver not being received prior to the period/year end, IAS 1 requires that the loans are classified as being repayable in less than one year.
