-Chipmaker Micron Technology Inc said it expects no impact on near-term production from component shortages driven by the Ukraine crisis, but costs are expected to rise. Ukraine's two leading neon suppliers, which produce about half the world's supply of the key chip-making ingredient, have halted their operations, threatening to drive up prices and worsen an ongoing semiconductor crunch. Global chip output was already under pressure after the pandemic drove up demand for cellphones, laptops and later cars, forcing some firms to scale back production. That same demand helped Micron forecast current-quarter revenue above estimates and deliver higher-than-expected results in the second quarter, sending shares up more than 4%.
