Three months ago, Nike gave a rosy outlook for the rest of the year as it benefited from consumers splurging on sneakers for running and hiking as they returned to their routines after over a year of staying at home.
Still, some analysts have cut their outlook for Nike's sales, predicting that lockdowns and factory closures in Vietnam, where about half of all Nike footwear is manufactured, will cause shortages during the crucial shopping season.
"We believe the risk of significant cancellations beginning this holiday and running through at least next spring has risen materially for Nike as it is now facing at least two months of virtually no unit production at its Vietnamese factories," BTIG analysts wrote in a note.
Many factories in Vietnam's manufacturing hubs have been shut or are operating with drastically fewer on-floor workers since mid-July as a surge in Delta variant cases forced the government to implement tight containment policies.
Other apparel companies including Abercrombie & Fitch and Adidas AG have taken a hit to their businesses due to production issues in Vietnam.
Some analysts, however, see Nike using its scale to offset the sales impact from Vietnam shutdowns.
Since the start of September, analysts have cut their full-year sales expectations for Nike to $49.81 billion from $50.34 billion due to worries about supply shortages
Full-year earnings per share estimates have also fallen to $4.24 from $4.33, according to IBES data from Refinitiv.
Nike's revenue for the reporting quarter is expected to have risen 17.7 percent to $12.46 billion from a year earlier.
The blue-chip stock has gained 11 percent this year, but is down about 10 percent from its record high hit in August.
