First Gen Shares Surge on Reported $5 Billion Takeover Approach.

MANILA, July 15, 2026 — Shares of First Gen Corporation climbed as much as 33% on Tuesday after reports that Indonesia's PT Barito Renewables Energy has made a $5 billion takeover proposal for Energy Development Corp. (EDC), one of Southeast Asia's largest geothermal power producers.

The reported offer fueled strong buying interest in First Gen, the Philippine energy company that holds a controlling stake in EDC. Investors interpreted the potential transaction as a sign of rising valuations for renewable energy assets across the region, where demand for clean power continues to accelerate.

Neither First Gen, Energy Development Corp., nor PT Barito Renewables Energy had publicly confirmed the reported proposal at the time of writing.

Investors Bet on Renewable Energy Growth

The market reaction reflects growing confidence in renewable energy companies as governments and businesses accelerate efforts to reduce carbon emissions and strengthen energy security.

Geothermal power has attracted increasing investor attention because it provides stable, round-the-clock electricity generation, making it a valuable complement to intermittent renewable sources such as solar and wind.

Analysts say high-quality geothermal assets have become increasingly attractive as investors seek long-term infrastructure investments capable of delivering predictable cash flows.

Strategic Value of Energy Development Corp.

Energy Development Corp. is among the largest geothermal energy producers in Southeast Asia, operating an extensive portfolio of geothermal, hydroelectric, wind, and solar assets across the Philippines.

A successful acquisition would significantly expand PT Barito Renewables Energy's presence in the regional renewable energy market while strengthening its portfolio of low-carbon power generation assets.

For First Gen, any potential transaction involving EDC would represent one of the most closely watched developments in the Philippine energy sector this year.

Regional Consolidation Gains Momentum

The reported bid comes as mergers and acquisitions within Asia's renewable energy industry continue to gain momentum. Rising electricity demand, supportive government policies, and increasing corporate commitments to decarbonization have encouraged companies to pursue strategic acquisitions to expand their clean energy portfolios.

Southeast Asia has emerged as a key investment destination due to its growing economies, expanding power demand, and abundant renewable energy resources. Investors are increasingly targeting established operators with proven assets and long-term growth potential

Market Outlook

While the reported proposal remains subject to confirmation and any required regulatory approvals, the sharp rally in First Gen's shares underscores investor confidence in the long-term outlook for renewable energy infrastructure.

If the transaction proceeds, it could become one of the largest renewable energy acquisitions in Southeast Asia, highlighting the region's growing importance in the global energy transition and reinforcing geothermal power's strategic role in future electricity generation.

Market participants will now watch for official statements from the companies involved, as well as any regulatory filings that could provide further clarity on the reported acquisition discussions.
