ESSA Industries Indonesia is trading at IDR 645, down 5.15%, amid broad Indonesian equity selling and weaker ammonia prices.

  • On September 11, 2026, IHSG fell 0.55% at the open and later neared 2% amid higher oil prices, Iran–U.S. tensions, and rising Treasury yields.
  • Ammonia prices fell from US$791.90 per ton on June 25 to US$496.90 on September 1, threatening ESSA’s second-half margins.
  • No new company-specific explanation was identified; prior first-half profit growth offers limited immediate support.
