Apple Inc on Thursday reported record sales in the holiday quarter, beating estimates as it benefited from high iPhone demand in China and withstanding supply chain constraints and Omicron variant disruptions.

Chief Executive Tim Cook had warned in October that chip shortages were affecting the manufacturing of most Apple products and could lead to over $6bn in lost sales.

Chief Financial Officer Luca Maestri told Reuters news agency in an interview that the effect had indeed been more than $6bn, but that constraints would decrease in the current quarter, ending in March.

“The level of constraint will depend a lot on other companies, what will be the demand for chips from other companies and other industries. It’s difficult for us to predict, so we try to focus on the short term,” he said.

With few rival phones debuting in the holiday shopping season, the iPhone 13, which started shipping days before the quarter began, led to worldwide phone sales revenue for Apple of $71.6bn, a 9 percent increase from the 2020 holiday season that handily beat Wall Street targets, according to Refinitiv data.

Apple’s smartphone market share in China reached a record 23 percent in the holiday quarter, when it was the top-selling vendor there for the first time in six years, research firm Counterpoint Research reported on Wednesday.

The company’s overall fiscal first-quarter revenue was $123.9bn, 11 percent up from last year and higher than analysts’ average estimate of $118.7bn. Profit was $34.6bn, or $2.10 per share, compared with analysts’ expectations of $31bn and $1.89 per share.

The coronavirus pandemic has accelerated the adoption of digital tools for communication, learning and entertainment, powering Apple to blowout sales across each of the company’s segments, including computers, accessories and tablets.

Apple’s services business, which covers paid apps such as Apple TV+, Apple Music and Apple Fitness+, also has seen a big bump. Services revenue rose 24 percent to $19.5bn, topping analysts’ estimates of $18.6bn. The company has 785 million paying subscribers across its offerings, an increase from 620 million a year ago and 745 million last quarter.

Sales for iPads fell 14 percent to $7.25bn compared with analyst estimates of $8.2bn, seeming to confirm industry predictions that iPads would have low priority for any scarce parts.

Sales for Macs rose 25 percent to $10.9bn compared with estimates of $9.5bn, and sales for accessories rose 13 percent to $14.7bn compared with estimates of $14.6bn.

For investors, the growing services business is helping mitigate production challenges. Apple is trading at 27 times expected earnings over the next 12 months. While down from as much as 35 a year ago, it remains above the company’s five-year average of 20 times expected earnings, according to Refinitiv.

Apple is facing antitrust pressure in the United States and Europe that could lead to new regulations that cut into its services revenue.

Late last month, the Dutch Authority for Consumers and Markets (ACM) ordered Apple to make changes for apps on offer in the Apple App Store in the Netherlands by January 15 or face fines, after it found that the US company had abused its market dominance by requiring dating app developers to exclusively use Apple’s in-app payment system.

Supply chain issues are dragging on and concerns remain about how long it will take Apple to deliver its next big product, such as an augmented reality headset or an electric vehicle.

Apple had reported strong customer response to its latest release, the AirTag, when the accessory began shipping in the fiscal third quarter of 2021.

Apple posted a rare revenue miss in the fiscal quarter ended September 25, which CEO Cook attributed to pandemic-related supply constraints and manufacturing disruptions that together cost the company an estimated $6bn in sales.

But smaller rivals are struggling to keep up with production, leading to Apple market share gains in regions such as China, said Angelo Zino of CFRA Research in a research note.

“Since Apple has many customised components going into the iPhones, Macs, Apple Watch and others and the scale (volume and price) at which it procures, Apple has been able to lock in suppliers’ capacities to timely produce those parts with lesser delays,” said Neil Shah of Counterpoint Research.
