Trading Update and Notice of Results

Positive momentum, trading ahead of market expectations

CML Microsystems Plc (the "Group" or the "Company"), which develops mixed-signal, RF and microwave semiconductors for global communications markets, is pleased to today issue a trading update for the first half of the current financial year (six-month period to 30 September 2022).

The Board is pleased to report that trading for the first half has been strong. Revenues are expected to be well ahead of last year on a constant currency basis and have been further boosted by an exchange rate tailwind. Gross margin has remained robust whilst overheads are in line with expectations. As a result, profitability is expected to be significantly ahead of management's earlier expectations.

At the current rate of trading and based on current exchange rates, the Board expects that for the full year ending 31 March 2023 both revenues and profitability will be ahead of market expectations.

Research and development activities, operational investments and the introduction to market of new products are all proceeding well, and the forward order book remains healthy.

The Board remains confident in the Group's strategy and its ability to deliver significant, sustainable growth over the coming years.

About CML Microsystems PLC

CML develops mixed-signal, RF and microwave semiconductors for global communications markets. The Group utilises a combination of outsourced manufacturing and in-house testing with trading operations in the UK, Asia and USA. CML targets sub-segments within Communication markets with strong growth profiles and high barriers to entry. It has secured a diverse, blue chip customer base, including some of the world's leading commercial and industrial product manufacturers.

The spread of its customers and diversity of the product range largely protects the business from the cyclicality usually associated with the semiconductor industry. Growth in its end markets is being driven by factors such as the appetite for data to be transmitted faster and more securely, the upgrading of telecoms infrastructure around the world and the growing prevalence of private commercial wireless networks for voice and/or data communications linked to the industrial internet of things (IIoT).

The Group is cash-generative, has no debt and is dividend paying.
