Kinross Gold Stock Down 11.4%: Why K and KGC Fell on a 2027 Guidance Cut
Kinross Gold closed at $34.50 in Toronto on Thursday, down 11.36%, after the company said in a September 23 update that it will fall short of its own production guidance for this year and next. Gold itself finished at $4,307.80, down 0.25%, and Wheaton Precious Metals fell 0.73%. The gap between the metal and this particular miner is the entire story of the session.
Around it, very little happened. The S&P/TSX Composite finished at 35,706.46, down 0.13%. The S&P 500 slipped 0.02% to 7,704.13 and the Nasdaq added 0.01% to 26,939.37. Underneath those flat closes the Canadian tape was split about as wide as it gets, with technology up 2.12% and the gold sector down 1.34%.
What Kinross actually said
In its operational and return of capital update, Kinross said it now expects full-year 2026 and 2027 attributable production “to be 2% to 3% below the low end of the previously disclosed guidance, with approximately 1.84 to 1.86 million gold equivalent ounces … expected per year.”
The causes are named and specific. At La Coipa in Chile, “a series of unprecedented winter weather events throughout the third quarter disrupted mining and milling activities,” compounded by higher than expected copper grades and lower recoveries in some sulphide ore. At Round Mountain in the United States, “lower mining rates and lower than expected grades and recoveries have reduced annual production expectations in 2026 and 2027.”
Two to three percent fewer ounces is not an 11% problem. The costs are.
The number that moved the stock
Kinross guided in July, in its second-quarter results release, to 2026 all-in sustaining cost of $1,730 per ounce sold, plus or minus 5%. The top of that range is about $1,817. Wednesday’s update puts AISC at $1,850 to $1,900 per ounce. The new range does not overlap the old one at any point. Production cost of sales moved the same direction, from $1,360 plus or minus 5% to $1,420 to $1,460.
Fewer ounces spread over the same fixed cost base is arithmetic every miner lives with. What turns it from a bad quarter into a repricing is the second year. Round Mountain’s shortfall is explicitly a 2026 and 2027 problem, so the market had to mark down two years of unit economics in one session rather than waiting to see whether the weather at La Coipa was a one-off.
Kinross also raised its return of capital target from 40% to 50% of free cash flow for 2026, on top of roughly $800 million already returned this year including about $655 million of share repurchases. That did not offset it, which is itself informative: buying back stock does nothing for the cost per ounce of digging the next one up. It is why we rank Canadian gold stocks on margin rather than ounces. Production and cost guidance move independently, and only the spread between them is what a shareholder owns.
The rest of the tape
Crude was the day’s other large move. WTI settled at $95.25, up 3.35%, after Bloomberg reported that a senior Iranian military official said Tehran could widen the war to the Indian Ocean if it is attacked, worsening the outlook for a deal to reopen the Strait of Hormuz. Canadian producers barely responded. The energy sector rose 0.37%, with Suncor up 1.31% and Canadian Natural up 0.98%. A 3% move in crude that producers largely ignore is usually the market treating it as a risk premium rather than a change in the price they will realize, which is the case for judging Canadian energy stocks on what survives $70 oil instead of on the print of the day.
Technology led, helped by a 5.94% jump in Meta after its Connect event drew attention to its AI products. Celestica rose 3.42%, Shopify 2.36% and Constellation Software 2.18%. Rate-sensitives lagged: utilities fell 1.06% and real estate 1.22%. That is consistent with where rate pricing sits. One-month CORRA futures settled September 23 implying about 11.63 basis points above the 2.25% overnight target, or roughly a 47% chance of a hike on October 28. The target has been at 2.25% since October 2025.
What is next
Statistics Canada publishes July GDP by industry on September 29, the last major domestic read before the Bank of Canada’s October 28 decision. For Kinross, the next scheduled test is third-quarter results, where the company has already told the market to expect about 425,000 attributable gold equivalent ounces.
