0108 GMT - Citi expects downside risk to FY27 earnings estimates for gold miner Northern Star. That is primarily due to weaker-than-anticipated forecast production and higher-than-expected costs. The company's Yandal and Pogo mines are the main sources of cost pressures, with all-in sustaining cost forecasts higher than Citi's expectations by 18% and 16%, respectively, the bank says. "Investor focus now shifts to KCGM ramp-up execution, whether Yandal's higher-cost base persists beyond FY27 and any changes in strategic direction under the incoming CEO and refreshed board," Citi says. It has a neutral rating and A$24.30 target on Northern Star. Shares are up 8.2% at A$24.38.
