We were very pleased to finally announce on 2 October 2023 the closing of the acquisition of Microwave Technology, Inc (“MwT”) but the unexpected delays in completing the transaction due to the associated regulatory processes, means that amalgamation activities that we hoped to have well underway by now have only just started. We are confident the assimilation work will be achieved successfully but realisation of the benefits will correspondingly move out beyond our initial expectations. That said, MwT substantially enlarges the Group’s product portfolio, complements our existing R&D capabilities and expands our system level understanding, allowing us to better capitalise on the market opportunities we see. Results and trading Despite the global macroeconomic backdrop, the Group’s financial performance for the six months to 30 September 2023 was positive and generally in line with our expectations. In a reverse of the comparative period of the prior year, revenue growth was tempered by the weakening of the average US Dollar rate against Sterling. The movement in currencies becomes less material at the profit level since costs below the revenue line are primarily denominated in other currencies. Revenue for the first six months increased by 5% to £10.58m (H1 FY22: £10.05m). Gross profit increased 4% to £7.94m (H1 FY22: £7.62m) and profit from operations, increased by 9%, before the £0.30m of external costs incurred in this half relating to the acquisition of MwT. Profit before taxation only marginally increased to £1.87m (H1 FY22: £1.83). The tax charge of 22% is higher than expected but reflects the changes in rules relating to R&D tax credits and a higher corporation tax rate. The result is that profit after taxation fell to £1.47m (H1 FY22: £1.87m), EBITDA was broadly flat at £3.23m (H1 FY23: £3.25m) and diluted EPS was 9.31p (H1 FY23: 11.58p). Cash balances at the end of the period stood at £20.95m (31 March 2023: £22.26m), a reduction of £1.31m after a £1.75m spend on share buybacks and £932k on dividend payments. Dividend The Board is recommending an unchanged half year dividend of 5.0p per share (H1 FY23: 5.0p per share), payable on 12 January 2024 to shareholders on the Register on 22 December 2023 with an ex-dividend date of 21 December 2023. Property Following the sale of the first parcel of land just prior to commencing the current financial year, building work has commenced at the Group’s Essex Headquarters site, Oval Park, including relocating the car parks to the rear of the buildings and is scheduled to be completed before the current year end. The remaining excess land, circa 15 acres, which was granted planning permissions in February 2023 was placed on the market early October. Further interest in the Group’s excess commercial property in Fareham, Hampshire is currently being explored, following cessation of the negotiations referenced in the Group’s annual report. Board and senior management At the time of the Annual General Meeting (“AGM”) in August, I announced my intention to revert to the role of Non‑Executive Chairman once the MwT acquisition had been completed and for this to coincide with additional appointments. In the last week we have strengthened the Board with the promotion of Mark McCabe to the position of Chief Operating Officer and the promotion of Michelle Jones to the senior management position of Director of Finance. These actions enhance the Board and leadership team bringing a diverse set of skills, expertise and experience whilst adding impetus. With these enhancements in place, I am stepping back to the position of Non-Executive Chairman with immediate effect. The formalities of appointing Nathan Zommer as a Non‑Executive Director are expected to be completed in the next couple of weeks following which an announcement will be made. Employees As I indicated at the start of my statement, this is a very demanding year and we clearly need the support of all employees to succeed with our ambitions. Throughout our operations globally, we are fortunate to have a great team of talented, hard-working, and dedicated employees and the Board thanks them all sincerely. Prospects and outlook The business continues to make good progress and has the appropriate blend of experience, enthusiasm and skills to continue to achieve its medium-term objectives. Despite the challenges brought by multiple headwinds facing businesses in all sectors, we currently expect full year revenues to be slightly ahead of current market expectations, with the majority of the growth attributable to the addition of MwT. Profitability is expected to be in line with current market expectations, with anticipated costs relating to the incorporation of MwT likely to temper further growth this year. Notwithstanding the macroeconomic environment, the Board has confidence in the strategy being followed and believes the robustness of our business model and a continued focus on sustainable growth will deliver a meaningful uplift in performance beyond the current year. Nigel Clark Non-Executive Chairman 5 December 2023 CML Microsystems Plc Half Yearly Report FY24 4 Operational and financial review Introduction The Group began the current financial year focused on growth, supported by relatively resilient end markets, a healthy order book and an evolving presence in new and emerging growth sectors. Amidst an inflationary environment, global economic uncertainty and a backdrop of several industry commentators predicting the semiconductor market will shrink by double-digit percentage points in 2023, the delivery of revenue growth through the first six-month period is a pleasing outcome and serves to highlight the resilience of our business. Equally welcome was the completion of the acquisition of Microwave Technology, Inc (MwT) on 2 October 2023, ending what was a protracted process due to US government national security considerations relating to the technology and skillset the business possesses. Work is now underway to unlock the global potential of the MwT product portfolio and to exploit the synergies that exist. First half progress has been positive at the revenue level, although larger than anticipated acquisition costs affected the underlying growth in operating profitability. Excluding these one-off costs, profit from operations increased by 9%. Nevertheless, prior investments in people and products coupled with the strategy being followed positions CML well to capture meaningful growth as the enlarged Group moves forward. Strategy The Group’s vision is to be the first-choice semiconductor partner to technology innovators, together transforming how the world communicates. Our focus is on the definition, development and marketing of standard semiconductor products that deliver compelling technical and commercial benefits to our customers. In turn, our customers utilise these solutions to develop and subsequently market end-products that are essential for the efficient and reliable transportation of voice and/or data across a predominantly wireless medium. The global communications market is huge, with a myriad of end-application areas ranging from mobile/cellular networks to precise positioning systems to short-range remote-control devices. Within this vast landscape of opportunity, CML is actively participating in a number of sub-markets that leverage our strengths and have excellent growth potential on a sustainable basis. These markets include mission critical communications, wireless networks and satellite, Industrial Internet of Things (“IIoT”) and more recently, broadcast radio. The addressable market in terms of semiconductor content easily exceeds $1bn. Continued investment in research and development is essential to enable CML to take full advantage of the large market opportunity available. Various new product programmes are underway comprising mixed-signal complex SoC projects with multi-year engineering cycles along with more rapid micro/millimetre wave developments. The blended result is delivering more products to market each year against what is a relatively stable absolute R&D spend. Markets and operations Across the prior full financial year to 31 March 2023, revenues from Group customers producing voice-centric wireless communications equipment delivered good growth, with the contribution from data centric applications slightly weaker due to some customers having procured inventory in excess of their end-market needs. In the first half of the current financial year, across most of the major customers,0 the voice equipment manufacturers once again achieved a solid advance in revenues whereas sales increases from data applications, such as IIoT, M2M, AMR were more moderate. We have seen early indications that order intake from this sector is set to improve but across the next few months, we are nonetheless taking a cautious stance. Geographically, performance across the first six months within Asia was good, with a 7.5% increase in sales revenue. However, the economic and geo-political situation in parts of the region, including China and Korea, has the potential to temper growth prospects. Within China, those customers that are producing end-products for local consumption have better forecast visibility than those reliant on exports. We therefore remain mindful of the backdrop globally and have moderated our expectations for the second half year period. The global voice communications markets addressed by the Group include the Land Mobile Radio/Private Mobile Radio (LMR/PMR) sector, encompassing high performance mission critical end-applications through to low-cost digital radio standards for use in the leisure and retail sector. For data‑centric markets, “smart everything” is driving data throughput increases within industry verticals such as agriculture, construction, smart grid/city and marine safety. CML has been a significant player in these end-application areas for many years and continues to invest appropriately in growth opportunities. CML Microsystems Plc Half Yearly Report FY24 5 Operational and financial review continued Markets and operations continued In recent years, building upon substantial markets knowledge and “design for manufacturing” capabilities for silicon devices, CML commenced the development of high‑performance Radio Frequency ICs (“RFICs”) and Monolithic Microwave ICs (“MMICs”) using compound semiconductor technologies, including GaAs and GaN. The twelve-month period to 31 March 2023 represented the first full financial year with availability of a number of new products that are marketed under CML’s SµRF brand and, over time, the flow of revenue from this expanding portfolio of IC’s is expected to constitute a very sizeable proportion of the Group’s total revenues. One key R&D initiative outlined at the time of announcing the FY23 full year results in June 2023, was a low-power radio receiver solution for Digital Radio Mondiale (“DRM”). DRM is a digital radio broadcast standard that has been adopted for wide area broadcasting in China, India and Pakistan and is expected to be deployed in several other nations. The DRM service provides high quality stereo audio across long distances and wide areas using low-cost, low-power infrastructure. The DRM module was formally announced at the International Broadcasting Convention (IBC) in Amsterdam in September and is a complete “antenna to speaker” module, containing all hardware, software, IP and patent licences required for a radio equipment manufacturer to easily realise a dual mode (digital and analogue) DRM capable receiver. The module offers a 60% cost reduction and 80% power reduction over existing DRM technologies in the market. At IBC, it was announced that the DRM module has been adopted by leading manufacturer Gospell Digital Radio Technology Co, Ltd for two new portable radio families. In support of the broadening product portfolio and expansion into new sub-markets, we exhibited at a number of trade shows through the period, including IMS Microwave Week in San Diego, European Microwave Week in Berlin and the International Broadcasting Convention (IBC) in Amsterdam. The multi-year investments in people, products and equipment have positioned us well to continue to expand the business. The traditional voice and data centric markets have provided strong foundations on which to expand into the micro/millimetre wave and, more latterly, broadcast radio arenas. Within these newer markets we are at the early stages of a journey to drive the business forward strongly and sustainably. Acquisition of Microwave Technology, Inc On 2 October 2023, immediately following the half year end, we completed the acquisition of Silicon Valley based semiconductor company Microwave Technology, Inc. (“MwT”). Founded in 1982, MwT is a recognised leader in the design, manufacturing and marketing of GaAs and GaN based MMICs, Discrete Devices, and Hybrid Amplifier Products for commercial wireless communication, defence, space, and medical (MRI) applications. The acquisition expands upon the Group’s growing product portfolio and complements its existing capabilities, providing essential knowhow and experience in high-frequency system level understanding, product manufacturing and packaging techniques. Work is now underway to ensure maximum market exposure for the product range acquired and investment areas have been identified that will improve USA-based production capacity and efficiency positioning the enlarged Group for growth in the years that follow. As a Group, CML now has internal final testing capabilities in the UK, Asia and the Americas, providing the flexibility required to address regional customer demands as they evolve. Financial review Sales revenues for the opening six-month trading period increased by 5% to £10.58m (H1 FY23: £10.05m) and include a currency headwind against the comparable period one year ago. Re-stated on a constant currency basis, revenues increased by 9%. Regionally, the improvements came from greater sales into Europe and the Far East, with the Americas territory posting a decline. Excess inventory across a handful of customers tempered further growth following the supply chain dynamics that have been a feature of the last two years. Higher sales levels combined with a slight reduction in gross margin delivered a gross profit of £7.94m (H1 FY23: £7.62m) representing an increase of 4%. Given cost of sale pressures, in part due to supplier raw material price increases that were experienced across multiple years, maintenance of the gross margin is a pleasing outcome at this interim stage. Distribution and administration (D&A) expenses were higher at £6.32m (H1 FY23: £5.77m) and whilst an increase over the previous year was expected, the prolonged process associated with and leading up to completion of the MwT transaction resulted in additional costs of £0.30m being incurred. Excluding third-party one-off costs associated with the MwT acquisition, profit from operations improved by 9% to £1.90m (H1 FY23: £1.75m). This is a key measure of the Group’s performance over the period under review, although under international accounting standards, the income statement does not highlight these costs as exceptional, hence the reported figure was lower at £1.61m. Finance income was noticeably up at £0.24m (H1 FY23: £0.10m) and reflected the improved deposit rates being achieved on the Group’s strong cash balances. Finance expenses were negligible. CML Microsystems Plc Half Yearly Report FY24 6 Operational and financial review continued Financial review continued Adjusted EBITDA came in at £3.23m (H1 FY23: £3.25m). Profit before tax was flat at £1.87m against £1.83m for the prior year first half. An income tax charge of £0.41m was recorded compared to a credit of £0.04m for the comparable period with the main contributing factors being lower UK R&D tax credits following changes to government policy and an increase in the corporation tax rate from 19% to 25%. The tax charge led to a diluted earnings per share figure of 9.31p against 11.58p for the prior year. For some time, the Group has deliberately operated with a raised level of inventory in keeping with its strategy to help minimise the impact customers feel from the supply chain dynamics over recent years. This year is no different and despite the slight drop in inventory levels to £2.19m (H1 FY23: £2.30m), expectations are for this to climb to a higher level over the next 12-18 months due to an expanded product range along with growth expectations. The Group continues to be debt free and had cash balances amounting to £20.95m at 30 September 2023 (31 March 2023: net cash of £22.26m). This follows investments of £2.01m in R&D activities, £0.60m in property, plant and equipment and shareholder returns of £2.57m by way of share repurchases (net of shares issued) and dividend payments. The strong balance sheet gives us a range of options as we look to win new clients and grow organically as well as the potential for future acquisitions in the medium-term.

The measurement policies the Group uses for segmental reporting under IFRS 8 are the same as those used in its financial statements. The Group is focused for management purposes on one primary reporting segment, being the semiconductor segment, with similar economic characteristics, risks and returns, and the Directors therefore consider there to be one single segment, being semiconductor components for the communications industry.
