On this edition of Stock Movers:

- West Pharmaceutical Services (WST) shares advanced as much as 28%, a record one-day climb, after the maker of packaging components for the drug industry boosted its adjusted profit and net sales outlook for the full year. 

- Chipotle Mexican Grill (CMG) shares plunged after cutting its annual outlook for the second time this year, suggesting that honey chicken and burrito giveaways haven’t been enough to offset a traffic slump that the company attributed to economic anxiety. Sales at established restaurants are now expected to be about flat for the full year, the company said Wednesday. It previously forecast the metric would expand by a low-single digit. The shares tumbled as much as 14% in New York, their biggest intraday drop since March 2020. The stock was down 12% this year through Wednesday’s close, among the worst performers in US restaurants. Chipotle had already cut its annual guidance earlier this year after economic uncertainty, among other factors, dinged results.

- Southwest Airlines (LUV) shares fell after the carrier said it expects economic turmoil to wipe out as much as $1 billion of its annual pre-tax profit this year and offered shareholders a much-reduced outlook for the balance of 2025. Earnings before interest and taxes for the year will be $600 million to $800 million, Southwest said in a statement on Wednesday that also included second-quarter results that fell short of analyst expectations. The carrier originally expected $1.7 billion in pre-tax profit at the start of the year. Southwest is one of a few companies so far to put a price on the fallout from President Donald Trump’s efforts to reset global trade, inflation and economic uncertainty that caused travel demand to collapse early this year. Most carriers pulled financial guidance in April, saying it was impossible to forecast demand.
