Allen & Overy (A&O) and Clifford Chance (CC) are among seven firms to have won roles on Chilean conglomerate Sigdo Koppers' $790m (£500m) acquisition of Belgian cement and mining services company Magotteaux, reports The Am Law Daily.

A&O took the lead advising Santiago-based Sigdo, a holding company for more than 40 industrial businesses in the heavy construction, engineering, manufacturing, and mining sectors.

Corporate partners Richard Cranfield, Pierre-Olivier Mahieu and Dominic Morris are leading a cross-border team representing Sigdo, while A&O finance partner Elizabeth Leckie is also working on the transaction.

The magic circle law firm handled due diligence issues in South Africa and India in tandem with Indian firm Trilegal.

Brazilian law firm Barbosa Muessnich & Aragao and Mexican firm Mijares Angoitia Cortes & Fuentes are also advising Sigdo, with Chilean firm Barros & Errazuriz serving as local counsel.

Magotteaux, a portfolio company of London-based private equity firm IK Investment Partners, turned to CC for lead counsel. David Walker, the firm's London-based global head of private equity, advised Magotteaux and IK on the transaction.

A team from Stikeman Elliott in Montreal led by corporate partner Gayle Noble is serving as Canadian counsel to Magotteaux on the deal, which was announced in late August.

Sigdo will acquire the company for about $680m (£430m). Including debt and other adjustments, the transaction's value increases to about $790m.
