Attock Refinery Limited (ARL) has announced a temporary shutdown of its Heavy Crude Distillation Unit, effective February 5, 2026, due to an unusual accumulation of Premier Motor Gasoline (PMG) inventories. This decision was communicated in a notice to the Pakistan Stock Exchange, as reported by ProPakistani and Business Recorder. The refinery cited reduced upliftment by oil marketing companies as the primary reason for the inventory build-up. To prevent a complete halt of operations, ARL decided to shut down the unit while ensuring that other crude units and downstream processing units remain operational. According to the Business Recorder, ARL assured stakeholders that it would continue to meet its committed supply volumes and maintain uninterrupted dispatches for the current month despite the shutdown.
