Who owns E.B. Mawson & Sons Pty Ltd & Controlled Entities
One company in the researched set discloses a stake in E.B. Mawson & Sons Pty Ltd & Controlled Entities, none of it sized by anyone who discloses it. E.B.

E.B. Mawson & Sons Pty Ltd, trading as Mawsons, is an Australian construction materials producer that quarries sand, gravel and crushed rock and supplies ready mixed concrete and landscaping products across regional Victoria and southern New South Wales. It runs roughly 36 quarries and pits, 46 concrete plants and seven landscape centres, along with mobile crushing and screening plant and its own delivery fleet, serving towns from Mildura and Bendigo to Yarrawonga and across the Goulburn Valley. The business was started in 1912 by E.B. (Barney) Mawson as a contracting firm and moved into concrete batching in the 1960s. Since 2007 it has been run as a joint venture between the founding Mawson family interests and the cement producer Adbri, and it expanded in 2021 by acquiring the Milbrae concrete, quarrying and mobile crushing business.

E.B. Mawson & Sons Pty Ltd & Controlled Entities files nothing with the SEC, so none of this comes from a filer record. The description was written for this site in August 2026 from Mawsons company history, Mawsons about page, AdBri buys half of Mawsons, ABC News, 11 December 2007 and Mawsons announcement on the Milbrae acquisition. The ownership figures below come from the holders' filings instead, and are sourced row by row.
The disclosed stakes
One row per position. Where a holder reports the same company in two share classes, both rows are shown rather than summed, because the class is part of a position's identity.
Where each figure comes from
A private stake has no ownership form behind it, so the source is always the holder's own filing or disclosure. Anything modelled says so, with the arithmetic.
- CRH plc. Australia. Products/services: Aggregates and readymixed concrete. Not consolidated: accounted for under the equity method. CRH's FY2025 10-K reports a single combined 'Equity method investments' balance of $737 million as of 31 Dec 2025 ($620 million at 31 Dec 2024, $649 million at 31 Dec 2023, per the Adjusted ROIC reconciliation in Item 7 MD&A) covering ALL of the entities in this exhibit table together. The filing does not disclose a per-investee carrying value, so value_usd is null here per the combined-balance rule; the combined figure is recorded in notes and unknowns, not assigned to this row. sourcesource 2
What this page is not
It is not a complete register. It lists the holders who happen to be inside the researched set and disclosed the stake themselves. A private company can have many other shareholders, and nothing here rules them out: venture investors, founders and employees usually appear in no public filing at all. Percentages are of E.B. Mawson & Sons Pty Ltd & Controlled Entities where a holder stated one, and are missing where no holder did.
