Chairman's statement FY2026 has been another important year in Filtronic's evolution. While the ﬁnancial performance reﬂects a deliberate period of investment following several years of signiﬁcant growth, the progress made across our customer base, technology roadmap, operational capabilities and strategic positioning gives the Board increased conﬁdence in the scale of the opportunity ahead. Filtronic enters its next phase of development with stronger foundations, broader market exposure and enhanced long-term growth potential. As a Board, our role is to provide eﬀective oversight, constructive challenge and long-term stewardship. We continue to ensure that management is positioned not only to deliver today's objectives but also to build a business capable of sustaining success over many years. During FY2026, the Board remained focused on those priorities: supporting investment in future growth, maintaining strong ﬁnancial discipline, strengthening governance and ensuring that the organisation continues to evolve as the business scales. Filtronic is a very diﬀerent company from that of only a few years ago. Today, Filtronic operates a higher-value, increasingly scalable and more strategically signiﬁcant business model, characterised by greater levels of repeat production revenue, longer duration programmes, deeper customer relationships and growing participation in critical communications infrastructure. These characteristics provide increased visibility, resilience and opportunity as the business continues to scale. The increasing scale of the business opportunities ahead, the strategic importance of our customer relationships and the complexity of our programmes require the Company to continue maturing in every aspect of its operations. The Board has therefore placed considerable emphasis on organisational capability, leadership development, succession planning and ensuring that the Company's governance and control environment develops in line with its ambitions. One of the Board's responsibilities is to balance opportunity with risk. Throughout the year we carefully considered the pace of investment in technology, facilities and people against the need to preserve the Group's strong ﬁnancial position. We remain convinced that disciplined investment is essential to securing Filtronic's long- term competitive advantage and creating sustainable shareholder value. At the same time, we continue to maintain a rigorous approach to capital allocation and risk management. The Board also continued to engage actively with shareholders during the year. We greatly value the constructive dialogue we have with both existing and prospective investors, whose feedback provides valuable insight into how the Company is perceived and where we can continue to improve. We remain committed to maintaining high standards of transparency, governance and communication as the Company continues to grow. The Board recognises that our success is built upon technical excellence, innovation and a commitment to customers. As the organisation grows, preserving these qualities while developing the leadership, processes and capabilities required of a larger international technology business remains a key priority. On behalf of the Board, I would like to thank all our employees for their continued commitment and professionalism and commitment to excellence. Their contribution is fundamental to Filtronic's success. I would also like to thank our customers, suppliers and shareholders for their continued trust and support. Looking ahead, the Board believes Filtronic is entering its next ﬁve years from a position of strength. The Group has established strong relationships with world-leading customers, expanded its addressable market, signiﬁcantly enhanced its manufacturing capacity and developed a technology roadmap aligned with some of the most attractive growth themes across space, defence and advanced communications. Together, these factors underpin our conﬁdence in the Company's long-term prospects. Supported by a strong balance sheet and net cash position, the Group retains the ﬂexibility to continue investing in technology, capacity and capability while maintaining appropriate ﬁnancial discipline. The foundations that have been established over recent years provide conﬁdence that the Company is well placed to deliver sustainable long-term growth and create enduring value for all of its stakeholders. The Group enters FY2027 with a strong order book and multi-year customer commitments which gives the Board a high level of conﬁdence to deliver the current market expectation. To address a key strategic priority, the customer concentration of our lead client is expected to reduce further whilst increasing revenue, reﬂecting the progress we are making on new customer acquisition. The market phasing and timing of our product road maps will mean that revenue and proﬁtability are expected to be weighted towards the second half of the year as we ramp to volume on our next-generation E band Gallium Nitride monolithic microwave integrated circuit technology ("GaN") programme. We look to the future with conﬁdence while remaining committed to the disciplined governance and long-term stewardship that will continue to underpin the Company's success.

Jonathan Neale Chair 3 August 2026 Chief Executive's review When I reﬂect on FY2026, I see a business that has reached an important inﬂection point in its evolution. While our reported revenue of £55.5 million was marginally below last year's record performance, we saw year on year organic sales growth and delivered adjusted EBITDA marginally ahead of adjusted expectations at £11.3 million (FY2025: £17.0m). While FY2026 reﬂects a year of continued investment, customer diversiﬁcation and operational scaling, I believe the fundamental strength of the business has never been greater. We enter FY2027 with enhanced visibility, broader market opportunities and signiﬁcantly improved strategic positioning. Over the past twelve months we have continued to broaden our customer base, expand our technology leadership, invest in manufacturing capacity and strengthen the organisation for the next phase of growth. As a result, we enter FY2027 with greater strategic momentum, improved visibility and a business that is materially stronger than it was a year ago. The market backdrop for Filtronic is arguably the most compelling it has been in the Company's history. Rapid growth in satellite communications, increasing defence expenditure and the escalating demand for secure, high- capacity communications infrastructure are driving sustained investment in the advanced RF technologies that sit at the core of our expertise. The convergence of the space and defence sectors is fundamentally changing the communications landscape. Governments are increasing defence spending at unprecedented levels, commercial space continues to scale rapidly, and both markets are demanding higher performance, greater bandwidth and more resilient communications networks. These long-term structural trends are creating a sustained increase in demand for advanced RF technology, particularly at mmWave frequencies where Filtronic has built a reputation as one of the industry's leading specialists. Our strategy has always been straightforward: develop technologies that solve the most diﬃcult RF engineering challenges, build deep partnerships with world-class customers, and continually invest ahead of demand. The progress we have made during FY2026 demonstrates that this strategy is working. Despite the signiﬁcant progress made over recent years, I believe we are still in the early stages of our journey. The markets in which we operate continue to expand rapidly, our technology roadmap is strengthening, and our ambition remains unchanged: to establish Filtronic as a globally recognised leader in advanced RF solutions for the world's most demanding communications applications. Perhaps the clearest evidence of this is the increasing diversiﬁcation of the business, both in terms of customers and the products we are delivering in our focus markets. Several years ago, we recognised that whilst our strategic relationship with our primary customer represented a transformational opportunity, long-term shareholder value would ultimately be created through broadening our customer base and applying our technologies across multiple markets and applications. During FY2026 we made signiﬁcant progress against this objective. Revenue from our largest customer reduced to 68% of Group revenue (FY2025: 83%). Importantly, this diversiﬁcation has been achieved while continuing to grow our engagement with our largest customer, demonstrating that expansion of the business is being driven by the addition of new programmes and customers rather than a reallocation of existing revenue streams. This not only reduces customer concentration risk but demonstrates that Filtronic's technologies are increasingly recognised by multiple global leaders. Importantly, our growth is not being driven by a single product or programme. We continue to expand our technology portfolio, extending our capabilities across higher frequency bands and investing in next-generation gallium nitride ("GaN") solutions that we believe will underpin the next wave of satellite communications and defence systems. In 2026 we launched new products in E, V and W-band, and sampled our ﬁrst full SSPA system at world leading 200W for a solid-state V-band ampliﬁer. As spectrum utilisation continues to migrate towards higher frequencies, our expertise in RF design and complex manufacturing positions us exceptionally well to address markets where technical barriers to entry remain high. Technology leadership alone, however, is not suﬃcient. Customers increasingly require partners capable of delivering both innovation and industrial scale. During FY2026 we therefore continued to invest heavily in the capabilities required to support substantially larger programmes. The successful relocation into our new headquarters represents far more than additional manufacturing space; it provides the operational platform from which we can support the signiﬁcant growth opportunities we see ahead, future prooﬁng our business to support in excess of £200 million revenues in the future. Alongside this investment, we have strengthened our engineering capability, enhanced programme management disciplines and continued to develop the talent that diﬀerentiates Filtronic.

A key highlight in the year was the ongoing development of our strategic relationship with our largest customer, including the award of a second major contract valued at $62.5m (£47.3m). The programme marks the ﬁrst production deployment of our E-band GaN technology and supports the transition of this platform from development into volume manufacture. We also continued to broaden our presence across the wider space sector. During the year, we secured an $8.0m contract with a US-based customer for the development and qualiﬁcation of high-performance ampliﬁer systems. This was followed, post year end, by a further contract award from the same customer to design a state-of-the- art, high frequency transmit/receive ("Tx/Rx") module. Together, these awards strengthen our position within the broader US space ecosystem and demonstrate the growing recognition of Filtronic as a trusted partner for advanced RF solutions to Tier 1 space players. They also reﬂect increasing demand for our diﬀerentiated technology across a widening range of satellite communications applications, supporting our strategy to diversify our customer base and create multiple long-term growth opportunities within the global space market. Alongside our continued progress in the US, we secured further aerospace and defence contracts across Europe, including multi-year programmes supporting Low Earth Orbit satellite constellation deployments and advanced defence electronics applications. These contract wins demonstrate our growing penetration of adjacent markets and further strengthen the diversiﬁcation of our customer base. One of the characteristics I value most within Filtronic is our willingness to invest for the long term. We have consistently prioritised sustainable value creation over short-term optimisation, investing in technology, facilities and people ahead of revenue. Whilst this inevitably creates periods where investment runs ahead of ﬁnancial returns, I believe it is precisely this discipline that has enabled Filtronic to establish itself as a trusted strategic partner to some of the world's most demanding technology organisations. Our ﬁnancial position provides us with the ﬂexibility to continue executing this strategy with conﬁdence. We maintain a strong balance sheet and healthy proﬁtability enabling us to continue investing organically while remaining disciplined in our allocation of capital. Looking ahead, I believe Filtronic has never been better positioned. We enter FY2027 with a record order book providing approximately 90% visibility against current market expectations, an increasingly diversiﬁed customer base, expanded manufacturing capabilities and a growing portfolio of proprietary technologies addressing attractive end markets. Combined with a strong balance sheet and a substantial pipeline of opportunities, these factors provide us with conﬁdence in both the near-term outlook and our longer-term growth potential. We possess the technology, customer relationships, manufacturing capability and talented people required to convert the plentiful opportunities we see into sustainable long-term growth. None of this would be possible without the commitment, expertise and determination of our people. Their passion for engineering excellence, innovation and customer success continues to deﬁne Filtronic and remains our greatest competitive advantage. I would like to thank every member of the team for their outstanding contribution throughout the year, together with our customers, partners and shareholders for their continued trust and support. The opportunities ahead are signiﬁcant. We remain focused on disciplined execution, continued innovation and delivering sustainable long-term value for all our stakeholders. I have every conﬁdence that Filtronic is exceptionally well placed to build on the strong foundations established during FY2026 and create substantial value in the years ahead. Nat Edington Chief Executive Oﬃcer 3 August 2026 Financial Review I am pleased to present the ﬁnancial review for the year ended 31 May 2026. This has been a year in which strategic investment and ﬁnancial discipline have moved in step with one another. The Group operates in a large and growing market opportunity, across space, defence and aerospace, and the Board's clear priority this year has been to invest ahead of that opportunity with conviction, while maintaining the ﬁnancial rigour that has always underpinned the Group's performance. Investment has been deliberate and targeted at a number of strategic areas including the internal capabilities needed to convert our growing opportunity pipeline. This includes the commercial capacity to broaden the customer register, engineering resource to advance our technology roadmap and customer programmes, and a

Page 6

new enlarged manufacturing facility in Sedgeﬁeld to support the business at greater scale. The Group has continued to maintain healthy cash reserves, despite this signiﬁcant investment for growth, and as a result enters the next phase of development with a strengthened balance sheet, a broader customer base, and the operational capacity to capitalise on the opportunity ahead. New customer acquisition has translated into a natural reduction in the dependency of our largest customer. This is evidenced through a series of contract wins, each to a diﬀerent customer, demonstrating execution against the objective of broadening the customer base. Importantly, this has been achieved alongside further entrenchment within our lead customer, as the period includes the Group's largest ever contract win with SpaceX for next- generation E-band GaN products. As a result of this work, the Group enters the new ﬁnancial year with a strong order book that substantially underwrites the current forecast numbers. Revenue As anticipated, this year represented a natural pause in the Group's recent trajectory of exceptional growth, with headline revenue decreasing marginally to £55.5 million (2025: £56.3 million). Excluding the impact of the factors outlined below, the Group delivered underlying year-on-year organic sales growth of 6% to £59.7m. · An amortisation charge to revenue of £3.5m (FY2025: £1.3m) for the SpaceX share warrant agreement reducing revenue by £2.2m year-on-year; and · A drag from the US dollar, in which a signiﬁcant portion of revenue is recognised, which weakened across the ﬁnancial year making each dollar sale less valuable than that of prior year by £2.0m. Importantly, there was also a sizeable reduction in customer dependency risk during FY2026 as the revenue from our largest customer reduced to 68% (2025: 83%), due to the commercial success described above, in widening our customer base as planned. We expect this to reduce further as a percentage in the outlook period as we convert our pipeline into order book with other major players across our markets. The space market continues to perform well, and this year has beneﬁtted from new customers including Airbus, Viasat and our recently acquired, but conﬁdential, US customer, adding meaningful revenue. The addition of these new logos will drive further growth in the space market into the next ﬁnancial year and beyond. Overall, this year saw a decline in space revenue of 12%, despite a volume increase due to the FX headwinds already mentioned, a charge to revenue of £3.5m for the share warrant charge and a planned strategic pricing strategy. Revenue from the aerospace and defence sector grew by 135%, demonstrating our ability to enhance our reach in this core market, in line with our guidance to the market. A large element of this revenue relates to the contract to supply airborne radar systems to our lead defence customer. As a result of the two large contract wins commencing which were announced in the year. The momentum continues to build, and we expect to deliver further year-on-year growth in the coming year to this sector. Demand in the critical communications market beneﬁtted from the rollout of the new platform for use in P25 networks although this is likely to replace the legacy combiner product going forward rather than being additive. This resulted in a 28% increase in revenue to this market. IFRS 15 'Revenue from Contracts with Customer' requires the SpaceX share warrants to be treated as a non-cash variable consideration payable to the customer. The charge to revenue in the year was £3.5m (2025: £1.3m). Operating costs and headcount Operating costs increased by 19% in the year to £25.1m (2025: £21.0m) demonstrating the controlled investment we continue to make to ensure we capitalise on the signiﬁcant market opportunity ahead. Most of this

Page 7

investment was people related particularly within engineering disciplines, business development, bid management and the manufacturing function. Engineering headcount has again increased substantially to support both product development and customer delivery. We now service a considerably larger portfolio of programmes, reﬂecting the growing opportunity within the space sector and the corresponding demand placed on our supply capabilities. Recruitment remains an area of active risk management, given the ongoing industry-wide challenge relating to the skills shortage in RF engineering. However, we are encouraged by recent success in attracting new talent and onboarding across our four UK engineering development sites, particularly at our Cambridge site, which has provided access to a deeper talent pool. To further strengthen our workforce, we are focused on building an organisation ﬁt for the future by increasing graduate recruitment and expanding our apprenticeship programme, ensuring a pipeline of skilled engineers to support our growth ambitions. This also aligns well with our sustainability strategy to provide high- quality jobs in the local community. To maintain ﬂexibility and manage workload peaks, we continue to partner with external engineering ﬁrms and contract engineering resource on a variable cost basis, especially where niche skills or additional capacity is required. This is a cost-eﬀective method of securing the relevant skills without the long-term commitment of hiring permanent employees. Manufacturing headcount increased as we converted temporary production staﬀ to permanent roles, allowing us to retain the skills developed within the team. This was particularly important as pipeline opportunities converted into ﬁrm orders and forward demand became more visible. The business development team has been substantially strengthened during the period to capitalise on the signiﬁcant market opportunity we see, and to expand coverage in terms of both customer volume and geographic reach, with Asia excluding China, now identiﬁed as a key territory for growth. To further professionalise the organisation, we have also established a bid management function to support sales and marketing, enabling us to service a greater number of bids in a timely and eﬃcient manner. This has the added beneﬁt of protecting capacity within the engineering team, allowing them to prioritise design rather than bid work. Salary-related costs remain the Group's largest overhead, representing 74% of total operating costs, increasing by 28% and totalling £4.1 million, which is a signiﬁcant driver of the overall rise in operating costs. This increase is reﬂected in headcount, which grew to 236 employees (2025: 186) as at 31 May 2026, and is analysed further below: Number 2026 2025 Manufacturing 109 89 Research and development (engineering) 92 72 Sales and marketing 12 6 Administration 23 19 Total headcount 236 186 Engineering spend as a percentage of revenue is a critical key performance indicator ("KPI") for the Group, reﬂecting its importance in driving long-term, sustainable growth. We have previously guided that we aim to control this R&D spend at around 13% of revenue; however, given the scale of the opportunity we are seeing and the position the Group has secured in the market, underpinned by its deep understanding of high-frequency RF engineering, we are pursuing the technology roadmap more aggressively to maintain our competitive advantage and position ourselves for success, in this substantial market opportunity. Consequently, spend has temporarily increased to 17% (2025: 12%). Other costs increased by 3%, in line with inﬂation, to support the ongoing scale-up of the business. Maintaining ﬁnancial discipline to tightly control these costs remains important in ensuring we deliver strong returns on both the top and bottom line. The increase reﬂects additional headcount in support functions, along with recruitment fees associated with ongoing headcount growth and higher insurance costs. Other operating income beneﬁtted substantially from the UK R&D tax regime. The Group recognises R&D tax credits, through the new merged scheme, within operating proﬁt. Within the year, operating income included a beneﬁt of £1.2m. Adjusted EBITDA The Group utilises an alternative performance measure ("APM") to provide a clearer view of underlying business performance. The APM adopted is adjusted EBITDA as it measures the quality of earnings without the impact of non-cash expenses such as depreciation, amortisation and share-based payments, including the charge associated with SpaceX share warrants which is recognised against revenue.

Page 8

Adjusted EBITDA for the year was £11.3m (2025: £17.0m), representing a 34% decrease, while operating proﬁt was £4.0m (2025: £13.4m), representing a 70% decrease. This reduction was driven partly by softer gross proﬁt, reﬂecting the deliberate pricing strategy to secure increased volumes, which resulted in a slight dilution in earnings quality, and partly by increased overheads arising from headcount growth. The table below shows the reconciliation of operating proﬁt delivered at £4.0m (2025: £13.4m) to adjusted EBITDA of £11.3m (2025: £17.0m). 2026 2025 Reconciliation of operating proﬁt to adjusted EBITDA £000 £000 Operating proﬁt 3,971 13,442 Depreciation 2,359 1,315 Amortisation 586 537 Share warrant charge 3,504 1,303 Share-based payments 837 414 Adjusted EBITDA 11,257 17,011 Taxation Our tax strategy is aligned with our core values and ﬁts within our overall corporate governance structure. Our strategy ensures that we comply with all tax laws wherever we do business and that we pay all taxes that we are legally required to pay when they fall due. To safeguard our reputation as a responsible taxpayer we do not participate in any tax planning arrangements that do not comply with either the legal interpretation or the spirit of tax laws. A tax credit of £0.8m (2025: £0.7m) was recognised in the year. The Group beneﬁts from R&D tax credits and the Patent Box regime, reﬂecting the advancement of science and technology embodied in the new products we develop, which reduce taxable proﬁt on qualifying R&D activities and products. We also make use of the Annual Investment Allowance ("AIA"), which provides tax relief on capital expenditure, and utilise ﬁrst-year allowances on capital purchases above the AIA threshold. Research and development costs ("R&D") Total R&D costs in the year before capitalisation and amortisation of development costs were £9.3m (2025: £6.7m). The Group incurred engineering costs on a mix of customer funded developments and progression of the technology roadmap. The Group remains committed to investing in R&D as a key driver for future revenue growth and consequently measures R&D spend as a KPI. Key areas of spend in the year included product development for space applications, in both the ground station and the payload, and aerospace and defence. The year ahead will see us continue to invest in the development of our own strategic technology roadmap and proprietary intellectual property ("IP"), enabling us to build long-term shareholder value in the years ahead. Where product development is customer speciﬁc, we seek to receive a Non-Recurring Engineering ("NRE") charge to maintain a healthy cashﬂow during the development phase of engineering projects and ensure commitment from our customer. When developing our own technology roadmap and IP, we invest from our own cash reserves unless we have successfully secured grant ﬁnancing. Technology developed for the LEO space market, across multiple frequency bands, in both ground station applications and the payload have been developed exclusively from internal funds this year. Consequently, we capitalised £2.3m of development costs in the year (2025: £1.5m). The Group capitalises its development costs in line with IAS 38 as set out in note 1 to the ﬁnancial statements. A reconciliation of R&D costs before capitalisation and amortisation can be seen in the table below along with details of our conservative approach to capitalisation of R&D: 2026 2025 Reconciliation of R&D costs £000 £000 R&D costs in income statement 7,481 5,625 Capitalisation of development costs 2,303 1,496 Amortisation of development costs (452) (440) R&D cash spend 9,333 6,681 When capitalising development costs, an impairment review is undertaken of each development programme to test the carrying value does not require impairment in line with IAS 36. Capital expenditure - plant and machinery and right of use assets (excluding property leases) An elevated level of capital expenditure was undertaken in the year to support expansion plans, including completion of construction work on the new, state-of-the-art facility at Sedgeﬁeld, which will serve the business

Page 9

well through the next phase of growth. Investment in plant and machinery related primarily to automated test equipment, providing the capability to service additional frequency bands under development, as well as new production lines to support the scale-up of operations. Total capital expenditure for the year was £10.3m (2025: £4.0m). Warranty provision In line with industry practice, the Group provides warranties to customers over the quality and performance of the products it sells. Reﬂecting a full risk analysis of current commercial contracts at 31 May 2026, the warranty provision was £0.4m (2025: £0.2m). Dilapidation provision The Group leases facilities at four sites in the UK and one in the USA with each of the leases requiring the site to be restored to its original condition. At 31 May 2026, the dilapidation provision was £0.3m (2025: £0.3m). Cash position and banking facilities The Group recorded a decrease in cash and cash equivalents to £12.9m (2025: £14.5m) at the year-end. Cash generated from operating activities in the year was £11.8m (2025: £13.8m) as adjusted EBITDA performance and advance customer payments drove cash generation, albeit with an oﬀset from an increase in working capital synonymous with improved trading. Net cash, when including all debt except property leases at the end of the period, was £10.8m (2025: £12.3m), whilst overall net cash including property leases was £7.3m (2025: £10.8m) due to the addition of the 10-year lease agreement signed in the year for the new state-of-the-art site at Sedgeﬁeld. The Group's banking facilities are provided by Santander UK plc ("Santander"). The Group has a £10.0m Revolving Credit Facility ("RCF") with Santander, which was uplifted from £5.0m in January 2026. This provides a high-level of cash headroom to facilitate future growth of the business should further ﬁnancing be needed. As at 31 May 2026 the facility was undrawn (2025: undrawn). Our covenants under this facility are debt service cover and interest cover measures, which have both been met throughout the year with substantial headroom available. Regular reviews take place of our foreign currency cash ﬂows. The Group undertakes hedging only where there are highly probable future cash ﬂows and to hedge working capital exposures. The Group does most of its trading with customers in US dollars which creates a requirement to put in place a level of hedging contracts against the US dollar surplus that is expected to arise. Going concern In assessing going concern, the Board have considered: · The principal risks faced by the Group which are discussed within the 'Risk management' section of the Annual Report; · The ﬁnancial position of the Group including forecasts and ﬁnancial plans; · The healthy cash position at 31 May 2026 of £12.9m (2025: £14.5m) and the additional headroom available through the undrawn RCF of £10m (2025: undrawn); and · Economic headwinds with the potential for customers to reassess their priorities, with opportunities postponed or curtailed. Following the above considerations, the directors are satisﬁed that the Group has adequate ﬁnancial resources to continue in operational existence for a period of at least 12 months from the date of this report. Accordingly, the going concern basis has been adopted in the preparation of the Annual Report for the year ended 31 May 2026.

Whilst the information included in this preliminary announcement has been prepared on the basis of International Accounting Standards in conformity of the requirements of the Companies Act 2006 as applicable to companies reporting under those standards, this announcement does not itself contain suﬃcient information to comply with IFRSs. The Company expects to publish full ﬁnancial statements within two months of this announcement. The ﬁnancial information set out above does not constitute the Company's statutory accounts for the years ended 31 May 2026 or 31 May 2025. The ﬁnancial information for 2025 is derived from the statutory accounts for 2025 which have been delivered to the registrar of companies. The auditor has reported on the 2026 accounts; their report was: (i) unqualiﬁed (ii) did not include a reference to any matters to which the auditor drew attention by way of emphasis without qualifying their report and (iii) did not contain a statement under section 498 (2) or (3) of the Companies Act 2006. The statutory accounts for FY2026 were ﬁnalised on the basis of the ﬁnancial information presented by the directors in this preliminary announcement and will be delivered to the registrar of companies in due course. Going Concern In accordance with corporate governance requirements and the statement of directors' responsibilities, and as disclosed in the Directors' Report, the directors have undertaken a review of forecasts and the Group's cash requirements to consider whether it is appropriate that the Group continues to adopt the going concern assumption. At 31 May 2026, the Group had cash at bank of £12.9m and access to an undrawn revolving credit facility of £10.0m. The Board recognises the uncertain economic and political environment that the world faces and has reviewed the business outlook to reﬂect this uncertainty. Cash ﬂow forecasts have been prepared to model various scenarios over a three-year period based on the Group's ﬁnancial and trading position, principal risks and uncertainties and strategic plans. A downside scenario was modelled, to stress-test the business, where programme curtailment and/or delays may adversely aﬀect forward-looking demand to levels lower than those initially modelled in the base case scenario including reduced demand from a major customer. A severe but plausible scenario was also modelled that took the downside scenario and modelled further programme delays. The scenarios modelled including the severe but plausible model, demonstrate the Group has adequate cash for the next twelve months from the date of the approval accounts.

New Accounting Standards There are a number of new standards, including, amendments to standards and interpretations that are eﬀective for ﬁnancial statements after this reporting period, but the Group has not adopted them early. None of these are expected to have a material impact on the results or ﬁnancial position of the Group. Notes to the Preliminary Financial Information for the year ended 31 May 2026 2 Segmental analysis IFRS 8 requires consideration of the identity of the chief operating decision maker ('CODM') within the Group. In line with the Group's internal reporting framework and management structure, the key strategic and operating decisions are made by the Board who reviews internal monthly management reports, budget and forecast information as part of this. Accordingly, the Board is deemed to be the CODM. The CODM has identiﬁed one operating segment within the Group as deﬁned under IFRS 8. In turn, this is the only reportable segment of the Group as the entities in the Group have similar products and services, production processes and economic characteristics. Therefore, there is no allocation of operating expenses, proﬁt measures or assets and liabilities to speciﬁc commercial markets. Accordingly, the CODM assesses the performance of the operating segment on ﬁnancial information which is measured and presented in a manner consistent with those in the ﬁnancial statements by reference to Group results against budget. The Group proﬁt measures are adjusted operating proﬁt and adjusted EBITDA, both disclosed on the face of the consolidated income statement. No diﬀerences exist between the basis of preparation of the performance measures used by management and the ﬁgures in the Group ﬁnancial statements. The Group has two customers representing individually over 10% of revenue each and in aggregate 78% of revenue. This is split as follows: • Customer A - 68% (2025: 83%) • Customer B - 10% (2025: 6%) Revenue by destination Total 2026 2025 £000 £000 United Kingdom 6,718 3,946 Europe 2,821 1,205 Americas 45,865 51,163 Rest of the World 125 4 ---------- ---------- 55,529 56,318 ====== ====== Split of non-current assets by location Total 2026 2025 £000 £000 United Kingdom 27,282 15,004 Americas 407 613 ---------- ---------- 27,689 15,617 ====== ====== Non-current assets relate to property, plant and equipment, right of use assets, goodwill and other intangibleassets and deferred tax.

Diluted earnings per share is calculated by adjusting basic earnings per share for the potential dilution from share options and share warrants. For the purposes of the diluted earnings per share calculation, it is assumed that all performance conditions attached to the share option schemes have been met as of the reporting date. The weighted average number of shares in issue during the year and the resulting earnings per share calculations are as follows: 2026 2025 £000 £000 Proﬁt for the year 4,557 14,049 ====== ====== '000 '000 Basic weighted average number of shares 219,797 218,854 Dilution eﬀect of share options and share warrants 36,603 13,389 ---------- ---------- Diluted weighted average number of shares 256,400 232,243 ---------- ---------- Basic earnings per share 2.07p 6.42p Diluted earnings per share 1.78p 6.05p ====== ====== Notes to the Preliminary Financial Information for the year ended 31 May 2026 6 Taxation

This related to the supply of E-band Solid State Power Ampliﬁers ("SSPAs") and new technology being developed for SpaceX for use in their Starlink constellation. The warrant agreement grants SpaceX the right to acquire up to 21,712,109 shares of the Company (equivalent to 10% of the Company's total share capital at the inception of the warrant agreement). The exercise price of vested warrants is 33.0p per share, based on the closing mid-market price at 23 April 2025, which is the date prior to signing the warrant agreement. The directors assessed the warrants and made a judgement that the warrants should be treated as equity instruments as deﬁned by IAS 32. This is because the warrants have a ﬁxed consideration at 33.0p per share for a ﬁxed number of units to exercise. Notes to the Preliminary Financial Information for the year ended 31 May 2026 10 Share Warrant Reserve (continued) The warrants have been recognised in the ﬁnancial statements based on the value at the date of signing of the agreement. An initial entry has been made in contract assets measured at fair value, but not subsequently remeasured, with the corresponding entry to equity. The initial fair value of the warrants at inception was £2,605,453, based on a fair value per warrant of £0.11 and the total number of warrants expected to vest over the 5-year vesting period. The directors have judged all of the warrants will vest, otherwise SpaceX and Filtronic would not have entered into the agreement. The warrants represent non-cash consideration payable to a customer under IFRS 15. Therefore, the contract asset, which eﬀectively represents a deferred volume rebate, is amortised to revenue based on when the units are supplied to SpaceX. In the year, there was no charge to revenue in the period relating to this tranche. The fair value of the warrants was determined using the Black-Scholes Model valuation method using a number of variables that require judgement including share price volatility, discount to the bid price, the risk-free rate and the expected life of the warrants. There are a number of variables that require judgement within this model including the risk-free rate, share price volatility, the vesting period and a bid price discount. Tranche 3

Page 18

On 19 March 2026, the Company entered into a second warrant arrangement with SpaceX expanding the Original strategic partnership entered into on 23 April 2025 to secure an increased allocation of business for the Group. The vesting of these warrants is dependent on certain performance conditions relating to the procurement of E-band SSPAs to support the Starlink constellation. The warrant agreement grants SpaceX the right to acquire up to 10,949,079 at 92.8p per share. The accounting treatment of the warrants has been judged by management and has been determined to be treated the same as tranche 1 and 2. An initial entry has been made in contract assets measured at fair value, but not subsequently remeasured, with the corresponding entry to equity. The initial fair value of the warrants at inception was £3,504,000, based on a fair value per warrant of £0.93 and the total number of warrants expected to vest over the 5-year vesting period. The directors have judged all of the warrants will vest, otherwise SpaceX and Filtronic would not have entered into the agreement. The warrants represent non-cash consideration payable to a customer under IFRS 15. Therefore, the contract asset, which eﬀectively represents a deferred volume rebate, is amortised to revenue based on when the units are supplied to SpaceX. There was a charge to revenue for tranche 3 in the year of £3,504,000. The fair value of the warrants was determined using the Black-Scholes Model valuation method using a number of variables that require judgement including share price volatility, discount to the bid price, the risk-free rate and the expected life of the warrants. There are a number of variables that require judgement within this model including the risk-free rate, share price volatility, the vesting period and a bid price discount. 11 Dividends The directors are not proposing to pay a dividend for the year ended 31 May 2026 (2025: £nil).
