Apple said sales growth in its current quarter, which ends in September, is likely to come in below Wall Street expectations as supply chain problems continue to weigh on the business. The company indicated it is having trouble securing enough parts to deliver products on time.

The weaker outlook overshadowed an otherwise solid third-quarter performance. Even with strong recent results, investors focused on the company’s warning that supply constraints could limit how much revenue it can generate in the near term.

The forecast triggered a sharp drop in Apple’s share price, reflecting concern that component shortages and broader supply chain disruptions are still affecting one of the world’s biggest technology companies. Apple’s comments suggest that demand may remain healthy, but converting that demand into shipments is becoming more difficult.

For the market, the key issue is not only Apple’s latest results but how long the parts shortage will last. With the iPhone maker facing ongoing supply hurdles, attention is now on whether production and deliveries can improve enough to support faster growth in coming quarters.
