After more than a decade, global energy giant Saudi Aramco has returned to the Philippines through a strategic investment in Unioil Petroleum Philippines, Inc.

Unioil confirmed today that it has sold a 25 percent stake to Aramco, a move expected to enhance its capabilities, drive innovation, and strengthen sustainability and customer satisfaction.

As part of the partnership, Unioil will introduce the Aramco and Valvoline brands to the local market.

Unioil CEO Janice Co Roxas-Chua described the deal as a “major milestone in Unioil’s 58-year history.”

“We are confident that this will equip us to accelerate growth, drive further innovation, and solidify our position as a leader in the wholesale and retail fuels market,” Roxas-Chua said.

For Unioil President Kenneth C. Pundanera, the investment aligns with the company’s goal “to be the fuel retailer of choice and support our customers with top-tier fuel solutions.”

With operations spanning Luzon, Visayas, and Mindanao, Unioil offers cleaner and advanced fuel products to customers.

Aramco’s return is particularly noteworthy given its history in the country.

The oil titan once held a 40 percent stake in Petron Corp. before selling it for $550 million to the UK-based Ashmore Group in 2008. Eventually, the stake was taken by business tycoon Ramon Ang, who now leads Petron.
