M&G (LSE:MNG) shows one of the more alarming-looking numbers in the FTSE 100, a Payout Ratio of minus 446.9%. Yet behind that figure lies a company whose Capital position has been strengthening, and whose shares have fallen from their August high, leaving the Yield above 6.5%. For readers trying to judge the reliability of an income stream, the gap between the headline ratio and the underlying capital picture is the central lesson.

Why the ratio is negative

As of 7 October 2026, M&G had an annual Dividend of 20.5p per share and a latest payment of 6.8p, a trailing 12-month yield of 6.6% and an indicated yield of 6.6%. The payout ratio of minus 446.9% arises because the calculation sets a positive dividend against a loss on the trailing Earnings measure. A payout ratio is normally the dividend divided by earnings per share, so when earnings turn negative the result flips sign. A negative ratio cannot be read as a level of cover in the ordinary sense, and it should not be mistaken for a sign that the dividend is more than four times covered.

The first-half figures explain the backdrop. M&G reported on 3 September an IFRS loss after tax of £165 million, compared with a profit of £248 million a year earlier. Short-term Investment return fluctuations reduced results by £551 million, including £325 million before tax linked to proposed Ground Rent legislation. Those movements affect statutory accounts heavily at a life and savings group, even when the underlying Business is performing well, because the value of Assets and liabilities is marked to market and can swing from period to period.

The measures that matter more

On the measures management emphasises, the half looked considerably better. Adjusted operating profit rose 15% to £435 million, with asset management up 24% and the life business up 9%. Operating capital generation was £372 million, down from £408 million a year earlier, while total capital generation rose to £375 million from £354 million. The Solvency II coverage ratio improved to 247%, from 242% at the end of 2025.

Net flows from the open business reached £2.4 billion, and the company expects low double-digit growth in adjusted operating profit for the full year. It also says it is on track for £2.7 billion of cumulative operating capital generation, excluding new business strain, over 2025 to 2027.

For a business of this type, capital generation and solvency are a better test of dividend affordability than statutory earnings. The Solvency II ratio compares the capital an insurer holds with the capital regulators require, so a ratio of 247% suggests a substantial buffer. Capital generation, in turn, shows how much surplus the business produces each year after meeting those requirements, and it is the pool from which dividends are ultimately paid.

A progressive record, at a measured pace

The Interim Dividend of 6.8p at M&G (LSE:MNG), up from 6.7p, is set at one third of the previous year's total under M&G's progressive policy. It went ex-dividend on 10 September and was due to be paid on 16 October. The full-year dividend grew by 2.0%, which is modest beside the yield.

M&G has paid a dividend for seven consecutive years and increased it for six of them. That record is short by FTSE 100 standards, reflecting the company's demerger from Prudential (LSE:PRU) in 2019. The pattern so far has been one of small, steady increases, which is what the formula for the interim implies. Because the first payment each year is fixed as a proportion of the prior year's total, the interim says little about trading in the current half. The final dividend carries the real information about how the board views the year.

For income investors, the combination of a high yield and a low growth rate describes a different proposition from a company offering a lower starting yield with faster increases. Here, the return comes mainly from the cash payment itself, and a rise of 2.0% would not keep pace with higher rates of inflation.

A falling share price lifts the yield

Part of the attraction of the current yield comes from the shares themselves. They have fallen by roughly 16% from their early August high, and because yield rises as price falls, the same Cash Dividend now represents a larger percentage. A forecast dividend of 21.1p for 2026 would represent a yield of about 6.9% on the same basis. Forecasts can change, however, and a higher yield can reflect market concern as well as a more generous payment. Readers should treat a rising yield as a prompt for questions about the reasons behind the share price move, rather than as a measure of safety.

What to watch

The next major marker is the full-year results and the final dividend at LSE:MNG, which will show whether the steady increases continue. Investors should also follow progress on bulk Annuity flows, the cost-to-income ratio against a 70% target, and how the proposed Ground Rent legislation develops, since it has already had a visible effect on reported results.

Asset management is the other half of the story. It earns fees on client assets, so its profit rises with net inflows and with market levels, and the 24% rise in its adjusted operating profit shows how quickly that line can respond. The life side is steadier but slower. Together, the two businesses give the group a mix of fee income and insurance margins that can support payments through different market conditions.

Another point of interest will be whether capital generation continues to cover the cash cost of the dividend comfortably. Any shift in the Solvency II ratio, either from market movements or from regulatory changes, would be an early signal of how much room the board has to continue its progressive approach.
