Highlights

• Impax Asset Management paid 10p in two dividends, ex-dividend on 19 February and 11 June 2026.

• The June payment of 2p was far smaller than the 8p paid in March, pointing to a lower interim.

• On a delayed price of 89.80p from 16 October 2026, the 10p total equates to an 11.14% yield.

• The firm manages funds focused on environmental markets, mainly alternative energy, water and waste, for institutional and private investors.

Two payments, very different sizes. Impax Asset Management (LSE:IPX) put 8p into shareholders' hands in March and followed with just 2p in July, leaving a trailing total that looks generous on today's share price but conceals a clear change of pace. Understanding why that matters is the heart of the story.

The two payments

The larger payment, 8p, went ex-dividend on 19 February 2026 and was paid on 20 March 2026. The smaller one, 2p, went ex on 11 June 2026 and was paid on 17 July 2026. Together they equal 10p. Neither is labelled as final or interim, and no special Dividend was found, so both are counted as ordinary. For LSE:IPX, the calendar shows one payment in the first quarter and another in the summer.

Yield and its limits

Dividing 10p by the delayed price of 89.80p from 16 October 2026 produces a trailing Yield of 11.14%. That number looks eye-catching, yet it blends a large earlier payment with a much smaller recent one. A yield built from the latest payment alone would look far lower. Forward guidance has not been confirmed, so investors should not read the trailing figure as a promise of what comes next. A trailing yield is a record of what was paid, not a forecast of what will be.

About the business

Impax is a London-based Investment manager. Through subsidiaries it provides investment services to funds focused on environmental markets, mainly alternative energy, water and waste, and manages funds and segregated accounts for institutional and private investors. It was founded in 1998 and was formerly Impax Group plc. It trades on AIM and did not appear in the FTSE 250 or FTSE SmallCap lists checked. Its Revenue comes largely from management fees, which depend on the value of Assets under management.

Why asset manager dividends move

Asset managers earn fees linked to the value of the assets they run. When markets rise or clients add money, fee income grows, and boards may feel comfortable raising dividends. When markets fall or funds see outflows, profit can fall quickly and payouts follow. Impax Asset Management has shown a step down from 8p to 2p across its two payments, so shareholders should look at the explanation in the next results rather than assume the earlier level will return.

Risks to weigh

The step down from 8p to 2p across the two payments is itself a warning that the distribution can shrink. Dividend cover should be checked in the company's filings, and a Payout Ratio near 95% of earnings, if accurate, leaves little headroom. A theme-focused manager can also be sensitive to the popularity of environmental investing. Check the next results announcement for the profit figure and the dividend policy.

Fees, markets and the dividend

The link between markets and fees is direct for Impax Asset Management (LSE:IPX). A rise in the value of environmental equities lifts assets under management and therefore revenue, while a fall has the opposite effect. Performance fees, where they apply, can add variability. Because fixed costs such as salaries do not fall with markets, profit can swing more than revenue. A dividend policy that pays out a high share of Earnings leaves less room to absorb such swings.

Reading the trailing yield correctly

The 11.14% figure is a mathematical result of dividing 10p by 89.80p, but it overstates the income that a new buyer would be likely to receive if the smaller interim becomes the pattern. A careful approach is to look at the most recent payment, multiply it by the number of payments expected in a year, and compare the result with the trailing total. If the two numbers differ widely, as they do here, the trailing yield should be treated with caution.

Dividend cover

Dividend cover measures how many times Earnings Per Share exceed the dividend per share. A figure above 1 means earnings are larger than the payment, and a figure below 1 means the company is paying out more than it earned. Cover is a useful guide, but Cash Flow also matters, because dividends are paid in cash, and one-off items can distort earnings in a single year.

What to watch next

The next signals for LSE:IPX are assets under management, net flows and the interim dividend. If the smaller 2p payment becomes the new interim level, the trailing yield will drift lower as the 8p payment drops out of the twelve-month window. If the larger payment returns, the yield could hold near its current level. Investors who want income should follow the trend in earnings as closely as the headline yield.
