Incitec Pivot Limited announced that, despite extensive efforts, it has been unable to secure an economically viable long-term gas supply to its Gibson Island (GI) plant beyond its current contract. As a result, IPL will cease manufacturing operations at the site at the end of the current natural gas feedstock supply arrangements which expire at the end of December 2022. Despite this decision to cease manufacturing with natural gas at the end of 2022, the feasibility study into industrial-scale production of green ammonia at GI will be progressed to potentially re-purpose the facility. IPL remains fully committed to being the leading supplier of quality fertilisers and soil health services to the agricultural sector. Urea, sulphate of ammonia and other specialty products will be sourced from IPL's existing international import supply chains to replace these manufactured products. IPL's Brisbane fertiliser distribution centre operation will continue beyond the closure of the manufacturing operations. The impact on IPL's earnings from January 2023 is as follows: Earnings from GI domestically manufactured products will cease. Dyno Nobel Asia Pacific will make alternative arrangements for ammonium nitrate production that utilises approximately 20,000 tonnes pa of ammonia that is currently supplied from GI. The financial impact of these alternative arrangements is expected to range between $5 million -$10 million pa. Stranded Corporate and insurance costs are expected to be approximately $10 million pa, representing costs that have previously been allocated to the GI plant. The decision to close the GI manufacturing facility after more than 50 years of operation is expected to impact up to 170 IPL employees.
