Mirrabooka Raises Payout and Opens the Reinvestment Door - Here's What Income Investors Should Do

Mirrabooka (ASX: MIR) has announced the terms for its dividend reinvestment plans ahead of the final and special dividend payment. For investors who think in terms of income streams rather than screen color, this is the kind of mechanics-level detail that matters more than the headline.

Here's what you need to know about the payout, the reinvestment terms, and whether this LIC still earns a place in an income-focused portfolio.

The Dividend

Mirrabooka has declared a fully franked final dividend of 6.5 cents per share plus a special dividend of 3.0 cents per share. Combined with the interim dividend of 4.5 cents paid in February, the total comes to 14.0 cents per share for FY2026 - up from 11.0 cents in FY2025.

Both components are fully franked at the 30% corporate tax rate. The entire payment is sourced from capital gains on which the company has paid tax, carrying an LIC capital gain component of 13.57 cents per share. For eligible Australian resident shareholders, that means a tax deduction in your return, which effectively boosts the net value of what you receive.

The payment date is August 21, 2026. Shares trade ex-dividend on July 30.

The Reinvestment Terms

This is where the mechanics get interesting. Mirrabooka offers two paths for reinvesting your dividend:

The DRP lets you automatically buy more shares with your cash dividend. You still receive franking credits and the LIC capital gain deduction, but you'll pay income tax on the reinvested amount. That makes it attractive for investors in lower tax brackets or self-managed super funds where the franking credits offset the tax bill.

The DSSP works the same way mechanically, but the shares aren't treated as a dividend. No income tax at receipt, no franking credits, no LIC deduction. You defer the tax event until you eventually sell. That makes it sensible for high-income taxpayers who want to compound without triggering a tax bill each period.

Both plans carry zero brokerage, zero GST, and zero transaction costs. You can elect to reinvest all, part, or none of your dividend, and you can join or leave at any time.

The pricing is set at a nil discount to the volume-weighted average price over the five trading days following the ex-dividend date. In plain English: you buy new shares at fair market value, no better, no worse. That protects existing shareholders from dilution and keeps the structure clean. Participation notices are due by 5:00 PM AEST on Monday, August 3.

The Underlying Picture

Behind the dividend, Mirrabooka reported a 63.6% increase in net profit to $13.0 million for the year ended June 30, 2026. Revenue from operating activities was up 36.1% to $15.5 million, driven by higher investment income, a stronger trading portfolio, and increased option portfolio income.

But the portfolio itself told a different story. The one-year return was negative 10.8%, compared to the benchmark's positive 7.8% including franking. Management explained the gap as a function of sector allocation: limited exposure to resources (which rallied), weakness across industrial and consumer names, and a valuation de-rating in software holdings amid AI disruption fears.

The tension between surging accounting profit and negative portfolio return is worth sitting with. The profit reflects realized gains and income already banked. The negative return reflects unrealized losses sitting in current holdings. For the dividend payer, the realized number is what matters - the cash is there, the gains have been taken, and the dividend has been declared. For the long-term holder, the portfolio drag is what deserves attention.

Management's longer track record does some of the heavy lifting on confidence here. Since inception in April 1999, MIR has delivered 11.6% per annum versus 8.5% for the benchmark. That's 27 years of compounding, not a single year.

Is the Income Stream Intact?

That's the question. The rest is detail.

On the durable side: the payout is sourced from realizable capital gains, the balance sheet is debt-free, and the management expense ratio sits at approximately 0.15% - among the lowest of any actively managed LIC.

On the cautious side: the LIC structure means dividends can swing from year to year depending on realized gains. MIR has a pattern of higher final dividends (often boosted by specials) and lower interim dividends - this year's 14.0-cent total sits on the higher end of recent payouts. If portfolio performance remains weak and realized gains dry up, the 27% dividend increase from FY2025 may not repeat.

Where MIR Fits in an Income Portfolio

Mirrabooka isn't designed to be a bond substitute or a growth engine. It's a low-cost wrapper around 50 to 70 small and mid-cap Australian companies, managed for long-term total returns with fully franked income. It works best when:

• You want diversified small-cap exposure without picking individual stocks
• Fully franked dividends with LIC tax efficiency fit your personal tax position
• You're comfortable accepting periodic underperformance in exchange for low costs and long-term active management
• You plan to reinvest dividends over years, not quarters

It doesn't work well if you need rock-steady income with minimal fluctuation, or if you're looking for short-term capital gains.

The Bottom Line

Mirrabooka's DRP and DSSP are priced fairly at nil discount, and the 14.0-cent total dividend for FY2026 represents a genuine step up from the prior year. The tax structure - fully franked with a meaningful LIC capital gain component - continues to work in shareholders' favor.

The portfolio underperformed this year. That's a real concern worth monitoring, not a sign of structural failure. The longer track record, the debt-free position, and the ultra-low cost base suggest the model remains sound.

For the income investor, the practical question is simpler than the portfolio debate: is the cash flow engine intact, do the reinvestment terms improve your long-term position, and does this holding play a clear role inside a diversified income architecture? On that basis, MIR still earns its place. If you're receiving the dividend, the DRP or DSSP is worth electing - the compounding mechanics work in your favor.
