Operational Review

EnSilica has continued to make strong operational progress, delivering record first-half revenues and growing profitability in H1 FY26. This performance reflects the execution of EnSilica's stated strategy to build a scalable fabless semiconductor business, our advanced ASIC design capability and expanded portfolio of production silicon, supported by sustained momentum across our core satellite communications and safe and secure semiconductor markets.

Design and non-recurring engineering ("NRE") activity during the Period remained robust, underpinned by both long-term customer engagements and new programme awards. These activities continue to support a growing pipeline of advanced ASIC programmes progressing through key execution milestones towards tape-out and production, providing the foundation for future compounding chip supply and royalty revenues.

Revenues for the six months ended 30 November 2025 increased by 37% to £12.7 million (H1 FY25: £9.3 million), reflecting growth across both chip supply and design-led revenues. Recurring revenues from chip supply of £3.9 million represented a 34% increase on the prior period, a key operational metric as the Group transitions from a consultancy-led model to a multiple revenue-stream business. The Group also delivered EBITDA profit of £1.7 million (H1 FY25: EBITDA loss of £0.2 million), demonstrating consistent financial maturity as both operating leverage and revenues increase.

Operational progress continued beyond the Period end, with further programme advancement, new contract awards, and additional purchase orders secured, strengthening both near-term revenue visibility and the longer-term supply pipeline.

Contract wins and other highlights for H1 FY26 include:

• Five ASICs now in the supply phase generating recurring revenues, with a broader portfolio of advanced ASIC programmes in the design phase supporting the growth of future chip supply
• Project advancement of multiple customer ASIC programmes towards tape-out, including successful prototype and test-chip activity to validate key design elements ahead of full device completion
• New definition and feasibility-stage contracts secured across satellite payload and other high-growth applications, strengthening the longer-term pipeline and providing pathways to potential multi-year NRE and supply agreements
• Receipt of a $1.4 million purchase order to progress a satellite payload ASIC into its next development phase, following completion of an initial feasibility study
• Award of a £5 million UK Contract for Innovation by the UK Government's Department for Science, Innovation & Technology to develop a secure, quantum-resilient processor ASIC for application across critical, national infrastructure
• Secured prototype development programme for an enhanced electronic road-tolling ASIC, striving for next-generation functionality and opportunities for a future commercial supply programme
• Demonstrated ability to scale production volume, with cumulative shipments exceeding 10 million ASICs on a long-running automotive supply programme
• Continued relevance of the Group's Post-Quantum Cryptography-ready security IP and architectures across focus markets, aligned with increasing regulatory and resilience requirements

Outlook

With 95% of business already booked, the Board has confidence in achieving management expectations for FY26. Revenues are expected to continue to be weighted towards the second half of the financial year, reflecting the timing of customer milestones and scheduled chip tape-outs.

The Group's diversified revenue model continues to gain traction, with a growing base of recurring chip supply revenues complemented by a strong order book of design and non-recurring engineering programmes. This blend is stimulating operating leverage and improving profitability, as more programmes progress from development into sustained production.

Increasing contributions from chip supply activities, together with disciplined investment in IP and engineering capability, are driving a phased reduction in cash consumption. As production revenues scale, the Board anticipates achieving positive monthly operational cash generation by the end of calendar year 2026. The Board looks forward to the future with confidence with the prospects of the business underpinned by longer term secular demand trends.

Finance Review

H1 FY26 saw significant revenue and EBITDA growth as a result of development revenues generated from the new ASIC design and supply customers, alongside further robust growth in supply revenues. Revenues grew 37% to £12.7 million compared to the £9.3 million achieved in H1 FY25. Chip supply revenues at £3.9 million continued their upward trajectory, whilst NRE revenues grew substantially, driven by the NRE contracts won in FY25. Consultancy revenues were subdued at £3.0 million due to the focus on the key NRE projects won in FY25, in line with our strategy to transition to a multiple-revenue-stream business.

Cash consumption slowed dramatically during the Period with the business generating an inflow of £0.8 million, helped by advance contract milestone payments. Operational cash outflows have also diminished sharply over the last 12 months with the Group well placed to become operationally cash flow positive on a monthly basis by the end of calendar year 2026, a goal supported by growing higher margin recurring supply revenues.

As part of the Group's strategic growth strategy and in conjunction with the Group's customers, EnSilica continues to co-invest in the development of customer ASICs, as well as its own intellectual property and know-how. As such, the Group has invested a further £3.1 million (H1 FY25: £2.6 million) in supply contracts and intellectual property assets with the expected return on the investment generated by long-term, high-margin, recurring supply or royalty revenues.

Financial Summary

Revenues

H1 FY26 Group revenues were £12.7 million (H1 FY26 £9.3 million) up 37%. Chip supply revenues continued their upward trajectory, increasing 34% to £3.9 million (H1 FY25: £2.9 million). This increase has been driven by growth in customer demand and in particular growing revenues from the industrial ASIC which taped out at the end of FY24. NRE revenues in the Period more than doubled to £5.8 million (H1 FY25: £2.2 million) driven by the NRE contracts won in FY25. As expected, Consultancy revenues were lower in the Period at £3.0 million (H1 FY25: £4.1 million) due to a large customer consultancy project not recurring in H1 FY26, as well as the business focus on supporting progression of the key NRE projects won in FY25.

The Group continues to focus on developing chip supply revenues through NRE projects as part of its fabless business model, with the established consultancy revenues providing a further reliable income stream.

Gross Margin

Gross margins in H1 FY26 of 38% slightly outperformed the 37% achieved in the prior year, mainly due to increased supply revenues. Margins are expected to continue incrementally increasing as the Group's higher margin chip supply revenues increase and become a larger share of the Group's overall revenues.

Operating Expenses

Operating expenses at £3.9 million were higher than in H1 FY25 (£3.6 million) due to investments in operational staff, as well as facility cost increases.

Other Income

Other income includes income received from government grants as well as the RDEC tax credit of £0.6 million.

EBITDA

As a result of the large increase in revenues, EBITDA increased significantly by £1.9 million from a loss of (£0.2) million in H1 FY25 to a profit of £1.7 million in H1 FY26.

Loss after tax

The Group's loss after tax decreased to £0.5 million (H1 FY25: £1.2 million loss) after the interest expense decreased by £0.2 million to £0.3 million in H1 FY26 (H1 FY25: £0.5 million) due to the one-off loan refinancing charges incurred in H1 FY25 not recurring in H1 FY26. Tax has been impacted by the deferred tax charge on intangible assets capitalised with no offsetting taxable losses in H1 FY26.

Headcount

Average Group headcount was increased in the Period to 199 (FY26: 179) by the recruitment of engineers to service the new NRE and design contracts won by the Group in the period, including the hiring of 16 engineers in Hungary.

Cash flow

The Company generated net cash flow from operations of £4.4 million after an EBITDA profit of £1.7 million and positive working capital movements of £2.7 million assisted by large customer contract upfront milestone payments received. The Company made investments in intangibles of £3.1 million, mainly driven by the co-development of customer projects, and spent £0.2 million on capital expenditure. Interest paid on loans and leasehold property liabilities amounted to £0.3 million, leading to total cash generation of £0.8 million.

Net proceeds from financing included loan repayments of £0.5 million and lease liability repayments of £0.3 million. The movement in cash in the period was therefore flat at £nil million.

General information

EnSilica plc is a public limited company incorporated in the United Kingdom, quoted on the AIM Market of the London Stock Exchange. The Company is domiciled in the United Kingdom, and its registered office is 100 Park Drive, Milton Park, Abingdon, OX14 4RY. The consolidated unaudited financial statements comprise the Company and its subsidiaries (together referred to as the 'Group'). The Company is a leading fabless design house focused on custom ASIC design and supply for OEMs and system houses, as well as IC design services for companies with their own design teams. The Company has world-class expertise in supplying custom RF, mmWave, mixed signal and digital ICs to its international customers in the automotive, industrial and communications markets. The Company also offers a broad portfolio of core IP covering cryptography, radar and communications systems. EnSilica has a track record in delivering high quality solutions to demanding industry standards. The Company is headquartered near Oxford, UK and has design centres across the UK and in Bangalore, India and Porto Alegre and Campinas, Brazil, and also Budapest, Hungary.

Basis of preparation

The consolidated interim financial statements of the Company have been prepared in accordance with UK-adopted International Accounting Standards (IFRS) as issued by the International Accounting Standards Board (IASB) and the Companies Act 2006.

Going concern

For the period ending 30 November 2025, the Group generated revenues of £12.7 million and an operating profit of £0.4 million; and generated cash flow from operations of £4.5 million. As at 30 November 2025 the Group held cash balances of £2.0 million and the Group's financing arrangements consisted of a loan of £4.9 million from Bank of Scotland. In considering the basis of preparation of the financial statements, the Directors have prepared a cash flow forecast for a period of at least 12 months from the date of approval of these financial statements based on the latest forecasts for the financial year 2026 and 2027. The Directors have undertaken a rigorous assessment of the 2026 and 2027 forecast and assessed identified downside risks and mitigating actions. The assumptions around project sales, staffing and purchases are based on management's expectations over the forecast period.

Under the current forecast scenarios, the Group has sufficient cash resources to continue in operation for a period of at least 12 months from the date of approval of these interim financial statements. In the event of a downside scenario crystallising, with delays to key revenue generating project milestones or new contracts not being secured in time, the Company could be at risk of breaching its financial loan covenants if an accommodation with Bank of Scotland could not be reached. Whilst the Company maintains a very good relationship with Bank of Scotland and is confident of securing its support, if the Company is unable to secure a waiver or amendment to its financial covenants, this would cause the outstanding loan to become immediately repayable which would give rise to a material uncertainty as defined in auditing and accounting standards related to events or conditions that may cast significant doubt on the entity's ability to continue as a going concern, and in such circumstances, it may therefore be unable to realise its assets and discharge its liabilities in the normal course of business.

• the Company's ability to continue to be successful in winning new customers and building its brand as demonstrated by the signing of 6 new development and supply agreements and two design agreements in the last 18 months with a lifetime value greater than $100 million,
• the Company's history of being able to access equity capital markets as evidenced by the raising of £5.2 million gross equity in May 2024, availability of factoring and discussions for additional debt headroom / further debt financing and,
• the Company's customer contracted order book with approximately 70% of revenues for the forecast period being contracted and,

Accounting policies

Basis of consolidation

The consolidated interim financial statements comprise the financial statements of the Company and its subsidiaries as at 30 November 2025. Control is achieved when the Group is exposed, or has rights, to variable returns from its involvement with the investee and has the ability to affect those returns through its power over the investee. Specifically, the Group controls an investee if, and only if, the Group has:

‣ Exposure, or rights, to variable returns from its involvement with the investee

‣ The ability to use its power over the investee to affect its returns generally, there is a presumption that a majority of voting rights results in control. To support this presumption and when the Group has less than a majority of the voting or similar rights of an investee, the Group considers all relevant facts and circumstances in assessing whether it has power over an investee, including:

‣ The contractual arrangement(s) with the other vote holders of the investee

‣ Rights arising from other contractual arrangements

Consolidation of a subsidiary begins when the Group obtains control over the subsidiary and ceases when the Group loses control of the subsidiary. Assets, liabilities, income and expenses of a subsidiary acquired or disposed of during the year are included in the consolidated financial statements from the date the Group gains control until the date the Group ceases to control the subsidiary. Profit or loss and each component of OCI are attributed to the equity holders of the parent of the Group and to the noncontrolling interests, even if this results in the non-controlling interests having a deficit balance. When necessary, adjustments are made to the financial statements of subsidiaries to bring their accounting policies in line with the Group's accounting policies. All intra-group assets and liabilities, equity, income, expenses and cash flows relating to transactions between members of the Group are eliminated in full on consolidation. A change in the ownership interest of a subsidiary, without a loss of control, is accounted for as an equity transaction. If the Group loses control over a subsidiary, it derecognises the related assets (including goodwill), liabilities, non-controlling interest and other components of equity, while any resultant gain or loss is recognised in profit or loss. Any investment retained is recognised at fair value.

Critical accounting estimates and judgements

Intangible assets - capitalisation, impairment and amortisation of development expenditure

Judgement

Estimation

Impairment of non-financial assets

Impairment exists when the carrying value of an asset or cash generating unit exceeds its recoverable amount, which is the higher of its fair value less costs of disposal and its value in use. The fair value less costs of disposal calculation is based on available data from binding sales transactions, conducted at arm's length, for similar assets or observable market prices less incremental costs of disposing of the asset. The value in use calculation is based on a DCF model. The cash flows are derived from the forecasts for the next five to seven years and do not include restructuring activities that the Group is not yet committed to or significant future investments that will enhance the performance of the assets of the CGU being tested. The recoverable amount is sensitive to the discount rate used for the DCF model as well as the expected future cash-inflows and the growth rate used for extrapolation purposes.

These estimates are most relevant to goodwill and other intangibles with indefinite useful lives recognised by the Group. The key assumptions used to determine the recoverable amount for the different CGUs, including a sensitivity analysis, are disclosed and further explained in Note 7.

Revenue

Estimation

The Company maintains complete and accurate records of employees' time and expenditure on each project which is regularly assessed to determine the percentage completion, and thereby whether it is appropriate to recognise revenues.

Segmental analysis

The Board continues to define all the Group's trading as operating in the integrated circuit design market and considers all revenue to relate to the same, one operating segment.

Disaggregation of revenue

Revenue in respect of the supply of products is recognised at a point in time. Design and related services, including income for the use of IP, are recognised over the period when services are provided.

The nature of the design services and projects is such that there can be significant customers as a proportion of revenue in any one year but that these may be different customers from year to year. During the six months to 30 November 2025 the largest customer contributed £2.5million (20% of revenue). Two other customers contributed over £1.0m of revenue during the period leaving just over 50% of the £12.7m made up of customers each contributing around 5% or less of revenue.

During the comparable period to 30 November 2024 there were three customers with sales of between £1.3 million and £2.5 million making up 65% of revenues, with a further two customers with sales of £0.5 million to £1.0 million resulting in the top five customers contributing 77% of revenue.

Alternative performance measures

These items are included in normal operating costs of the business but are significant cash and non-cash expenses that are separately disclosed because of their size, nature or incidence. It is the Group's view that excluding them from operating profit gives a better representation of the underlying performance of the business in the year.

The Group's primary results measure, which is considered by the directors of EnSilica plc to better represent the underlying and continuing performance of the Group, is EBITDA as set out below. EBITDA is a commonly used measure in which earnings are stated before net finance income, amortisation and depreciation as a proxy for cash generated from trading.

Capitalised development expenditure relates to developed intellectual property in respect of circuit and chip design. The recoverable amount of a cash generating unit (CGU) is assessed using a value in use model across each individual project that forms the intellectual property that has been capitalised. The value in use for each portion is dependent on the expected life cycle of the CGU using a discount factor of 11.5% (H1 FY25: 11.5%), being the cost of capital for the CGU.

Trade and other receivables

In November 2024, existing borrowings with carrying value of £3.6 million were redeemed by way of a Term Loan for £3.0 million, and a Revolving Credit Facility (RCF) of £3.0 million, which was drawn down in 2 tranches. The loan liability is stated net of unamortised loan issue costs of £216,000 at 30 Nov 2025 (30 November 2024: £290,000).

The term loan of £3.0 million is secured by fixed and floating charges over the assets of the group and bears interest at rates of 3.5% over the Bank of England Base Rate. It is repayable in monthly instalments over the period to November 2027.

The revolving credit facility of £3.0 million is secured by fixed and floating charges over the assets of the group and bears interest at the Bank of England Base Rate plus 2.5%.
