Half Yearly Report

SOFTWARE RADIO TECHNOLOGY PLC

("SRT" or the "Group")

HALF YEARLY REPORT FOR THE SIX MONTHS ENDED 30 SEPTEMBER 2012

SRT, the AIM-quoted developer and supplier of maritime identification and tracking technologies, announces its unaudited interim results for the six months ended 30 September 2012.

Results

For the six months ended 30 September 2012, revenue and profit after tax were £3.47 million and £0.15 million respectively. As at 30 September 2012, the Group had cash of £1.55 million and no borrowings. Both profit after tax and cash benefited from the receipt of a R&D tax credit of £0.32 million.

The gross profit margin for the period was 42% due to the unusually high revenue weighting of our lower margin products, coupled with a provision against surplus components used in products which have been replaced by our new ranges. Given that our product margins range from 30% to 80%, there will be variations in our overall margin, but we remain comfortable with our target long term gross profit margin of 50%.

Administrative expenses increased by 21% over the comparable prior period, primarily due to the amortisation of development expenditure as sales of new products commenced.

Stock and work in progress of £3.59 million reflected our build-up of stock to meet expected orders from multiple markets, in particularly the EU Inland Waterway, EU Fisheries, Russian and Asian markets. With a larger product range, more markets and poor demand timing visibility, coupled with an average six month production lead time for all our products due to individual component lead times, we expect our stock and WIP levels will continue to fluctuate significantly going forward.

During the first half we continued to provide Class A units to customers addressing the EU Inland Waterway and the first phase of the EU Fisheries market. The Inland Waterway mandate has a completion deadline of 31 December 2012 and we expect the remainder of the applicable vessels not yet fitted to comply with the regulations either immediately before the deadline or within a few months thereafter when enforced by inspection.

The deadline for the first phase of the EU Fisheries mandate was 31 May 2012 and we saw demand for Class A devices over a period of five months straddling that date. We expect a similar pattern for the next phase which has a deadline of 31 May 2013, resulting in the majority of revenue for this market falling into our next financial year.

We have a significant number of Class A devices in stock and due for delivery and so can react quickly to order flow. However, timescales are not under our, or our customers', control and the outcome for the full year, both in terms of revenue and overall margin, will be dependent on the timing and rate of orders, particularly in respect of the Inland Waterway mandate.

Products and Markets

During the first six months SRT continued its planned new product development investment programme. Both the 'Search And Rescue Transponder' (SART) and 'Aids To Navigation' (AtoN) products are nearing completion, with SART expected to commence first deliveries in December and AtoN during the first quarter of 2013. In addition to our core product developments we have undertaken various customer-specific modifications to products, such as the integration of GLONASS into our Class A and Class B products for the Russian market, the completion of a number of custom OEM products based on our modules and supporting various customers to integrate our modules into their own target enclosures and products.

SRT now has a global customer base of over 70 customers, purchasing a variety of AIS modules and OEM products. Of these we estimate that 40 are addressing the growing non-mandated 'core' AIS market where owners of commercial and leisure vessels choose to purchase AIS devices without any regulatory requirement. During the first half we continued to work closely with our customers to complete and expand their AIS product offerings and expect this work to continue through the second half. I am pleased to report that we have started to see the benefits of this investment as revenues from our core market customers have grown steadily during the first half. As our customers complete the integration of our new devices into their product portfolios and AIS becomes more mainstream and a standard fit on larger leisure and commercial vessels in years to come, we expect to see continuing and accelerating revenue growth in this segment with regular orders from customers addressing these large and diverse markets.

We have seen maritime domain awareness (MDA) become increasingly important, with AIS being adopted as a critical element of next generation MDA projects worldwide. These projects are in various stages of implementation and range in size from a few to many hundreds of thousands of vessels. In the last few years, we have seen mandates come into effect in Europe, Russia, China and Mexico creating substantial markets that SRT, in partnership with our customers, has begun to address.

In 2011 Russia announced a national commercial mandate and in September this year we commenced the supply of GLONASS enabled Class A and Class B devices to our Russian customer who placed orders totalling $1.6m during the first half. We expect this market to be a significant opportunity for SRT over the next three years.

After a five year gestation period, the AIS mandate in Mexico commenced, resulting in an order worth $3.8m for our Identifier product. Our strategic stock of Identifier components purchased in November 2011, enabled us to manufacture and ship half of the order during the period, and by working with our component suppliers and manufacturing partner, we will ship the balance during December 2012. We understand that up to a further $16m of Identifiers will be required to complete the programme over the next two years.

Over the last six months we have actively supported our customers to conduct a range of demonstrations and trials in Asia, India, Middle East and S. America. These trials are a significant investment for the authorities, SRT and our customers and are often indicative of a project moving towards its implementation phase and therefore the commencement of orders for SRT. Based upon current information we expect to see one or two of these projects entering their implementation phase during our second half and therefore generating some initial small orders, with further increasingly substantial orders to follow.

In September 2012, we commenced the soft launch of our new Aids to Navigation (AtoN) module and product solutions. This is a complex, high value device deployed on buoys and other navigation markers to provide electronic warnings and other environmental information to authorities and mariners. This product range benefits from our latest generation core technology which has resulted in a very small device with an exceptionally low power consumption which is the critical factor for this product. Initial market reaction to our soft launch was very positive. We are now in discussions with a range of potential customers and expect formal contracts to be signed during the second half and first deliveries of product to commence during the first half of the next financial year. We believe that a substantial market exists for this product.

Summary

I am pleased to be reporting solid progress against our long term strategic plan to be a global leader in maritime domain awareness technologies and product solutions. Our next generation product development programme is nearing completion and we have made excellent progress integrating our new products into an expanded customer base, thus positioning SRT to benefit from the growing core markets and the wide number of project opportunities which are now active or pending.
