• Honeymoon Q3 FY26 production of 203 klbs U3O8 drummed, C1 cost of $60/lb (US$41/lb)
• FY26 production guidance reduced to 1.40-1.45 Mlbs U3O8 drummed due to adverse weather conditions
• FY26 C1 cost guidance of $36-40/lb (US$24-26/lb) and AISC guidance of $60-64/lb (US$40-42/lb) reconfirmed

Boss Energy's Q3 FY26 report highlighted operational difficulties at the Honeymoon project, with production of 203 klbs U3O8 drummed, down 56% from the previous quarter. This was primarily due to the impact of heavy and repeated rainfall events during March, which restricted site access and limited the delivery of key reagents. As a result, Boss has revised its FY26 production guidance to 1.40-1.45 Mlbs U3O8 drummed, down from the previous guidance of 1.6 Mlbs. However, the company has reconfirmed its FY26 C1 cost guidance of $36-40/lb (US$24-26/lb) and AISC guidance of $60-64/lb (US$40-42/lb), indicating that it expects to deliver towards the upper end of the range. During the quarter, Boss also made progress on the New Feasibility Study for Honeymoon, including advancement of a new Mineral Resource Estimate and the calibration of a reactive transport simulation model. The company also continued the development of wide-spaced wellfield trials at Honeymoon and East Kallaroo, which it believes could deliver a substantial reduction in the cost structure. Additionally, Boss provided updates on its Gould's Dam and Jason's Deposit projects, noting that the development pathway for both has been accelerated over the past six months.
