Marine Products Corporation (NYSE:MPX) stock is about to trade ex-dividend in 4 days. The ex-dividend date is usually set to be one business day before the record date which is the cut-off date on which you must be present on the company's books as a shareholder in order to receive the dividend. 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. Thus, you can purchase Marine Products' shares before the 9th of August in order to receive the dividend, which the company will pay on the 10th of September.

The company's next dividend payment will be US$0.14 per share, and in the last 12 months, the company paid a total of US$0.56 per share. Looking at the last 12 months of distributions, Marine Products has a trailing yield of approximately 5.6% on its current stock price of US$9.98. Dividends are a major contributor to investment returns for long term holders, but only if the dividend continues to be paid. We need to see whether the dividend is covered by earnings and if it's growing.

Dividends are typically paid out of company income, so if a company pays out more than it earned, its dividend is usually at a higher risk of being cut. Marine Products paid out 74% of its earnings to investors last year, a normal payout level for most businesses. 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. Marine Products paid out more free cash flow than it generated - 140%, to be precise - last year, which we think is concerningly high. We're curious about why the company paid out more cash than it generated last year, since this can be one of the early signs that a dividend may be unsustainable.

Marine Products does have a large net cash position on the balance sheet, which could fund large dividends for a time, if the company so chose. Still, smart investors know that it is better to assess dividends relative to the cash and profit generated by the business. Paying dividends out of cash on the balance sheet is not long-term sustainable.

While Marine Products'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 Marine Products's ability to maintain its dividend.

Have Earnings And Dividends Been Growing?

Stocks with flat earnings can still be attractive dividend payers, but it is important to be more conservative with your approach and demand a greater margin for safety when it comes to dividend sustainability. If earnings fall far enough, the company could be forced to cut its dividend. That explains why we're not overly excited about Marine Products's flat earnings over the past five years. Better than seeing them fall off a cliff, for sure, but the best dividend stocks grow their earnings meaningfully over the long run.

Another key way to measure a company's dividend prospects is by measuring its historical rate of dividend growth. Marine Products has delivered 14% dividend growth per year on average over the past 10 years.

To Sum It Up

Should investors buy Marine Products for the upcoming dividend? It's not great to see earnings per share have been flat and that the company paid out an uncomfortably high percentage of its cash flow over the past year. Cash flows are typically more volatile than earnings, but this is still not what we like to see. It's not an attractive combination from a dividend perspective, and we're inclined to pass on this one for the time being.

With that being said, if you're still considering Marine Products as an investment, you'll find it beneficial to know what risks this stock is facing. Our analysis shows 1 warning sign for Marine Products and you should be aware of this before buying any shares.
