A dramatic plunge gripped Semirara Mining and Power Corp. (SMPC) shares on Monday, plummeting 21.39% after news surfaced that their long-held coal operating contract for Semirara Island faced denial of renewal.
The stock price tumbled to a low of P25.40 during trading before settling at P26.10 – a significant drop from Friday’s closing price of P33.20. This sudden shift sent ripples through the market, raising questions about the future of the nation’s largest coal producer.
The decision stemmed from a legal opinion sought by the Department of Energy (DoE) from the Department of Justice, effectively preventing a direct renewal of the 50-year contract. Instead, the DoE announced plans to open the opportunity to competitive bidding later this year.
While SMPC stated they hadn’t received official notification, the company emphasized their decades of experience on Semirara Island as a powerful advantage in the upcoming bidding process. They highlighted their established infrastructure, technical expertise, and extensive equipment as key strengths.
The original contract, dating back to 1977, granted SMPC exclusive mining rights on the island for 35 years, extending until 2012. A subsequent 15-year extension kept operations running until 2027, but the company’s recent request for another 13-year extension met with resistance.
Semirara Island holds the largest coal deposits in the country, making SMPC responsible for approximately 97% of the nation’s domestic coal output. This dominance underscores the high stakes involved in securing the renewed contract.
Despite producing 12.9 million metric tons of coal in the first nine months of 2025, driven by both exports and internal power plant needs, SMPC experienced an 18.7% decline in coal revenues, reaching P24.73 billion due to falling prices.
Coal revenues contribute nearly 45% of SMPC’s core net income, which itself saw a 37% decrease, landing at P9.89 billion. This financial vulnerability makes the contract renewal even more critical for the company’s stability.
Analysts warn that the uncertainty surrounding the contract could significantly impact future earnings. Losing the contract would force SMPC to either find alternative coal sources or fundamentally reshape its business model to avoid shrinking profit margins.
The potential impact extends beyond SMPC, with concerns raised about increased power generation costs at the Calaca power plants, which heavily rely on Semirara coal. The ripple effect could be felt throughout the energy sector.
Even if SMPC wins the bid, analysts caution that the long-term outlook hinges on the specifics of the new contract – including its duration, production limits, royalty rates, and tax obligations. These terms will ultimately determine the company’s future profitability.
Without a secure replacement for its Semirara Island operations, experts predict a substantial drop in SMPC’s valuation, a decline investors are likely to immediately reflect in the share price. The future remains uncertain, but SMPC’s established presence and operational capabilities position them as a strong contender in the upcoming bidding war.
