A Semiconductor Business That Pays a Dividend

CML Microsystems Plc (LSE:CML) develops mixed-signal, RF and microwave semiconductors for global communications markets, including industrial internet of things and satellite applications. Unlike most smaller technology companies, it has a long history of paying dividends to shareholders, supported by a cash-rich and debt-free balance sheet.

With a dividend yield of 3.79%, LSE:CML sits inside the 2% to 4% range. However, the dividend has not been covered by Earnings during the recent industry downturn, making sustainability the central question for income investors.

FY26 Results: A Year of Two Halves

On 17 June 2026, CML published full-year results for the year ended 31 March 2026 under the headline of a strong second-half recovery and strategic progress positioning the company for renewed growth. Revenue fell 10.7% to £20.45 million from £22.90 million. Gross Profit was £12.89 million, giving a gross Margin of 63% compared with 69% a year earlier, reflecting a higher contribution from non-recurring engineering income.

The company reported a small pre-tax loss that narrowed compared with the previous year. Issues reported at the interim stage, relating to securing supply of certain core products and unplanned engineering work to restore shipments of specific products, were successfully resolved. Looking ahead to the 2027 financial year, CML said it expects solid progress in both operating profitability and sales revenue.

The $30 Million GNSS Contract

A key highlight of the year was a landmark 12-year design and supply agreement valued at more than $30 million with a leading global manufacturer of industrial GNSS equipment. Management sees the deal as validation of CML's evolution into a systems-level partner rather than simply a component supplier, and it provides long-term revenue visibility.

Dividend Policy and Recent Payments

The board recommended a final dividend of 6.0p per share, unchanged from the previous year, taking the total for the year to 11.0p, also unchanged. The final dividend was paid on 21 August 2026 to shareholders on the register on 7 August.

CML has maintained its 11.0p annual dividend for several years. In 2021, it also paid a 50p Special Dividend following the sale of a subsidiary. The board has stated that it has maintained its dividend policy throughout a multi-year transitional period as a signal of confidence in the long-term potential of the business. It has also said it wants to reach the stage where payments are covered by trading profitability and cash generation as quickly as possible.

Dividend Cover and Funding

At present, the dividend is not covered by earnings. With a small statutory loss per share in the latest year, the payout is being funded from the company's cash reserves. The total annual cost of the dividend is roughly £1.8 million, based on around 16 million shares in issue.

The Balance Sheet provides a cushion. Cash increased to £12.80 million at the year end from £9.92 million, and the company has no debt. Net Assets rose to £51.45 million, including a £1.88 million Revaluation surplus on its remaining Oval Park land and buildings.

Market Sentiment

The shares fell about 6% on results day to around 277p as investors focused on the revenue decline and continued losses. With a Market Capitalisation of around £45 million to £50 million, LSE:CML is a micro-cap. On investor forums and social platforms, some see the company as an undervalued, debt-free technology business with a supportive dividend, while others worry that prolonged lack of earnings cover could eventually force a cut.

Risks to the Dividend

The main risk is that the expected recovery in profitability takes longer than hoped, leaving the dividend reliant on cash reserves for an extended period. Semiconductor Demand is cyclical, and customer inventory adjustments can cause sharp swings in revenue. Currency movements also matter, as a large share of sales is overseas. The board has made clear that it will keep the dividend policy under review in light of financial performance and the macroeconomic environment.

Verdict: Is the 3.79% Yield Sustainable?

CML Microsystems Plc (LSE:CML) offers a 3.79% yield that is currently funded by cash rather than profits. The debt-free balance sheet and growing cash position mean the dividend can be sustained in the short term, and the $30 million GNSS agreement improves long-term visibility. However, sustainability over the medium term depends on CML returning to profitability in the 2027 financial year, as management expects. Income investors should monitor the interim results closely for evidence that earnings are rebuilding towards dividend cover.
