Listed Investment companies occupy a distinctive place in the income landscape, and Mirrabooka Investments (ASX: MIR) is among the better-known names focused on small and mid-cap Australian and New Zealand shares. Managed within the Australian Foundation Investment Company stable, Mirrabooka has cultivated a following among investors who value fully franked dividends and a long-term approach, and with a trailing Yield of about 5.62%, it remains a talking point for income seekers.

Dividend Snapshot

A trailing yield near 5.62% indicates security holders have received roughly 5.62 cents of income for every dollar invested at the recent price, a figure that moves inversely with the share price. For FY2025, Mirrabooka paid a final dividend of 6.5 cents per share, fully franked, taking total Ordinary Dividends for the year to 11 cents per share, also fully franked. That was lower than the 13 cents paid in FY2024, a figure that had included a 2.5-cent special dividend. Full franking is a hallmark of Mirrabooka's distributions and a key part of its appeal, since eligible Australian shareholders can access franking credits that enhance the effective after-tax income. As a LIC, Mirrabooka aims to smooth dividends over time using its reserves, which can help cushion payouts through periods of market volatility.

What Is Supporting the Dividend?

Mirrabooka's dividends are funded from the income it earns on its investment portfolio, primarily dividends received from the smaller companies it holds, together with realised gains and accumulated reserves. The FY2025 payout came against a backdrop of lower profitability, with full-year profit easing to around $7.9 million from $10.7 million a year earlier. A defining strength of the LIC structure is the ability to draw on profit reserves and franking-credit balances to maintain relatively stable dividends even when underlying income dips in a given year. This is why the reduction from FY2024 largely reflected the absence of the prior Special Dividend rather than a collapse in the ordinary payout.

What Income Investors Should Watch

The key variables for income investors are the performance of small and mid-cap markets and the level of income the portfolio generates. Smaller companies can be more volatile than large caps, and their dividend flows can be less predictable, which feeds through to Mirrabooka's own income. The company's capacity to sustain fully franked dividends depends on ongoing portfolio income, realised gains and the depth of its reserves. Investors may watch the net Tangible Asset backing, whether the shares trade at a premium or discount to that asset value, and the direction of the ordinary dividend as distinct from any special payments. Dividend sustainability remains subject to market conditions, and a trailing yield can be lifted simply by share-price weakness.

Outlook

Mirrabooka offers income investors a franked-dividend profile combined with exposure to smaller listed companies, wrapped in a structure designed to smooth returns over time. The FY2025 result showed a softer year for profit and a return to an ordinary-only dividend after the prior special, yet the LIC's reserves and franking position underpin its ability to keep paying fully franked distributions. The trailing yield will continue to shift with the share price, and future dividends remain contingent on portfolio performance rather than guaranteed by history. For those seeking franked income with a small-cap tilt, Mirrabooka stays worth monitoring, with realistic expectations about market cyclicality.
