Sibanye-Stillwater trims US PGM output forecast after five‑week strike

Sibanye-Stillwater announced that its US platinum‑group‑metal (PGM) production for 2026 will be 15% lower after a five‑week strike at its Montana operations. The company now expects US output of 245,000‑255,000 ounces, down from the prior guidance of 280,000‑300,000 ounces. Third‑quarter production fell 19% year‑on‑year to 59,417 ounces, and gold output dropped 12% to 155,449 ounces. EBITDA rose 9% year‑on‑year to 10.8 billion rand, while the firm raised its cost guidance in response to the labor disruption.

The reduced US PGM supply tightens a market that already relies heavily on imports, potentially supporting prices and affecting downstream users such as automotive and defense manufacturers. Higher cost guidance signals increased operating expenses for the remainder of the year.
