The updates reflect material changes in guidance—notably higher all-in iron ore costs (58–62 vs. 52–56 US$/t) and significantly lower all-in nickel costs (10,000–11,500 vs. 12,000–13,500 US$/t)—driven by revised assumptions on exchange rates, commodity prices, and operational performance. This is a forward-looking operational and financial guidance update that would affect investor assessment of the company's cost structure and profitability outlook, but it does not fit the discrete event categories (no earnings release, no M\u0026A, no impairment charge disclosed).
