A Philippines brewing company plans to raise $4 billion as it transitions from a brewer and food maker into an investor in mining, airlines, roads and energy.

Brewer San Miguel and its parent company, San Miguel Corp. (OTCMKTS:SMGBY), have made more than $5.6 billion worth of purchases since 2008, Bloomberg reported.

Part of CEO Roman Ang’s strategy has been to invest in companies like Manila Electric Co. (OTCMKTS:MERVF), which has tripled in value. At the same time, Ang has gained control of Petron Corp. (OTCMKTS:PNENY), the country’s largest refiner.

“Ang has been an opportunistic entrepreneur and he has seen better opportunities, so he’s selling assets that have already paid off to fund these new ventures,” said Marvin Fausto, chief investment officer at BDO Unibank (OTCMKTS:BDOUF). “He’s moving assets from one to the other, liquidating those where he has made money, and financing opportunities that will eventually pay off, like toll roads and airlines.”

San Miguel is looking to boost its revenue to $50 billion in five years, and the company announced 40 acquisitions worth about $8 billion since 2000, according to Bloomberg.
