Pinned straw:
Gosh, the author is a bit harsh in calling Brickworks "no moat" imo @Chagsy
Over the last decade, according to Commsec, Brickworks has averaged a 28% net margin (very much juiced by non-cash gains from property revaluations and its Soul Patts stake) but still well above what you'd expect from a no-moat business. To be fair, the Building Products segment is commoditised and cyclical, and much lower margin. Still, I'd argue that its scale, vertically integrated operations, and strategic location of clay pits offer some not-insignificant competitive advantages.
But i'm just nit picking.
I do agree that the share price jumps are a bit overdone. Soul Patts reckons the merger will unlock $1.2 billion in value, largely from simplifying the cross-shareholding structure, improving liquidity, and boosting index appeal. But on the day of the announcement, Brickworks alone jumped by that amount in market cap, with Soul Patts adding another $1.8 billion. So, the combined gain of ~$3 billion far exceeds what they suggested the restructure might unlock.
That tells you one of two things: either management lowballed the upside, or the market is getting well ahead of itself.
