VF Corporation, whose brands include such names as Vans, The North Face, and Timberland, announced that it cut its full-year revenue forecast as it struggles to stock store shelves due to delivery delays caused by worker shortages at factories in Vietnam in a press release shared at the end of January.

The company’s shares fell 2.3% in premarket trading, as it also warned of a slower-than-anticipated growth in its main brands, Supreme streetwear and Vans. Worker shortages in Vietnam have hurt many retail companies that are just beginning to recover from forced factory closures due to COVID-19 lockdowns last year, the release stated. Port congestion and higher freight charges have also added to the issues currently being faced in the apparel industry.

VF Corp. said in the release that COVID-19-related manufacturing capacity constraints affected third-quarter results, but added that it expects capacity be back to near full in the coming weeks. The apparel maker forecasts fiscal 2022 revenue of about $11.85 billion, just below its prior estimate of about $12 billion.

The Denver, Colorado-based company’s total revenue rose 22% to $3.62 billion in the third quarter that ended on Jan. 1st, according to IBES data from Refinitiv.
