It looks like Chemring Group PLC (LON:CHG) is about to go ex-dividend in the next three days. The ex-dividend date is one business day before the record date, which is the cut-off date for shareholders to be present on the company's books to be eligible for a dividend payment. The ex-dividend date is an important date to be aware of as any purchase of the stock made on or after this date might mean a late settlement that doesn't show on the record date. In other words, investors can purchase Chemring Group's shares before the 15th of August in order to be eligible for the dividend, which will be paid on the 6th of September.

The company's next dividend payment will be UK￡0.026 per share. Last year, in total, the company distributed UK￡0.072 to shareholders. Based on the last year's worth of payments, Chemring Group has a trailing yield of 1.8% on the current stock price of UK￡4.03. Dividends are an important source of income to many shareholders, but the health of the business is crucial to maintaining those dividends. We need to see whether the dividend is covered by earnings and if it's growing.

Dividends are typically paid from company earnings. If a company pays more in dividends than it earned in profit, then the dividend could be unsustainable. Chemring Group paid out more than half (64%) of its earnings last year, which is a regular payout ratio for most companies. That said, even highly profitable companies sometimes might not generate enough cash to pay the dividend, which is why we should always check if the dividend is covered by cash flow. Chemring Group paid out more free cash flow than it generated - 174%, to be precise - last year, which we think is concerningly high. It's hard to consistently pay out more cash than you generate without either borrowing or using company cash, so we'd wonder how the company justifies this payout level.

While Chemring Group's dividends were covered by the company's reported profits, cash is somewhat more important, so it's not great to see that the company didn't generate enough cash to pay its dividend. Were this to happen repeatedly, this would be a risk to Chemring Group's ability to maintain its dividend.

Have Earnings And Dividends Been Growing?

Stocks in companies that generate sustainable earnings growth often make the best dividend prospects, as it is easier to lift the dividend when earnings are rising. Investors love dividends, so if earnings fall and the dividend is reduced, expect a stock to be sold off heavily at the same time. For this reason, we're glad to see Chemring Group's earnings per share have risen 17% per annum over the last five years. Earnings have been growing at a decent rate, but we're concerned dividend payments consumed most of the company's cash flow over the past year.
