Editing Rinker Group (section)

==History==
Rinker Group was established as a separate entity in 2003 through its demerger from [[CSR Limited]]. CSR had earlier purchased Rinker Materials, which was founded by Marshall "Doc" Rinker and A.V. Hansen in 1926. The company has approximately 14,000 employees and as of 2004 has sales of around US$3,700 million and a market capitalization of about US$5 billion.  Its net profit was US$492 million in the 2003-04 financial year.

In the Companies Target Statement over [[Cemex]]'s takeover bid they showed the group's result from 98 (they were at this time owned by Commonwealth Sugar Refineries). They revealed that the compound average growth rate for EBITDA is 24.8 while sales grew at 14.3% average compound. Taking these figures it's evident that in nine fiscal years, their EBITDA margin has doubled from 14% to 28%. This means on average over the last 9 years 32.9% of any amount that sales grow by (14.3%) will result in 32.9% sales growth directly translated into EBITDA.

Rinker Group was acquired by CEMEX, the world's third-largest cement producer, through its subsidiary CEMEX Australia Pty Ltd. in a US$14.2 billion takeover bid. As of June 2007, CEMEX owned a 67.3% stake in Rinker Group. The [[chief executive officer]] was David Clarke, who had long worked in CSR's heavy building products division.  The chairman of the board of directors was [[Hector Medina from Cemex|Hector Medina]], executive vice-president of CEMEX.  The other board members were also nominees from CEMEX.

CEMEX Australia was sold to Holcim in June 2009 as part of an AUD 2 billion takeover bid and is now known as Holcim Australia.
The deal included the Readymix and Humes business units and CEMEX's 25% stake in Cement Australia (one of Australia's major cement manufacturers) but did not include the US-based Rinker Materials Corporation.<ref>{{cite web| url = https://www.smh.com.au/business/holcim-snaps-up-cemex-australia-for-2b-20090615-c8gh.html| title = Holcim snaps up Cemex Australia for $2b| date = 15 June 2009}} </ref> In 2016, Cemex sold its Rinker Materials pipe business to Quikrete.<ref>{{cite web | url=https://www.powderbulksolids.com/wire-cloth/cemex-selling-us-reinforced-concrete-pipe-unit-500m | title=CEMEX Selling U.S. Reinforced Concrete Pipe Unit for $500M | date=29 November 2016 }}</ref>
