SAN FRANCISCO (REUTERS) - The iPhone is back.

Apple on Tuesday (Jan 28) reported sales and profits for the holiday shopping quarter above Wall Street expectations, powered by a rise in iPhone sales for the first time in a year and soaring demand for add-ons like AirPods wireless headphones.

The strong performance outweighed concern about the coronavirus in China, a major market as well as manufacturing hub for Apple, and a slight revenue miss in the company's closely watched services business, which includes the new Apple TV+ streaming offering.

Shares of Apple rose 2 per cent in after-hours trade.

Apple gave a revenue forecast for the quarter ending in March above Wall Street expectations.

Chief executive Tim Cook told Reuters the company was using a wider-than-normal prediction range because of the uncertainty created by the coronavirus outbreak in China. Cook said Apple has shut one store in China and reduced hours at others and is restricting employee travel due to the virus.

"We have limited travel to business-critical situations as of last week," he said. "The situation is emerging and we're still gathering lots of data points and monitoring it very closely."

Apple has suppliers in the Wuhan area, the heart of the outbreak, but has alternatives, Cook said. He said that factories outside Wuhan area also faced delayed reopenings after the Lunar New Year holiday until Feb. 10, but that Apple has tried to account for the delayed restart of work in its wider revenue forecast.

In terms of consumer demand within China for Apple's products, Cook said Apple is seeing reduced foot traffic in its stores there. It has reduced hours at some stores and is also checking the temperatures of employees. Cook also said that Apple's channel partners - third-party stores that sell its products - are also facing some closures.

"Apple also is forecasting a stronger Q2 than analysts predicted, but the fact that the coronavirus is spreading in unpredictable ways in China, where Apple has most of its hardware built, could upset this optimistic forecast," said eMarketer principal analyst Yoram Wurmser.

The number of active iPhones, computers and other devices owned by customers, called the installed base, grew by 100 million to more than 1.5 billion over the past year, and Apple executives set a new target of 600 million paid subscribers for music, TV, gaming and other services by the end of calendar 2020.

Apple's share price has more than doubled since Cook warned a year ago that the company was likely to miss financial targets for its biggest sales quarter of its fiscal 2019. In the year since, Apple slashed prices in China, one of its most important markets, to rekindle sales there. The company also made a push into paid services, rolling out a credit card with Goldman Sachs and subscription gaming and television services last year.

"Services are important, but the trajectory is heading on target. I feel they've made good progress on that front," said Hal Eddins, chief economist for Apple shareholder Capital Investment Counsel. "It's easier to take a small miss like that in context when they also lift the Q2 revenue figures higher."

Net profit hit an all-time high of US$22 billion (S$29.9 billion) on record quarterly revenue of US$91.8 billion for the quarter ended Dec 28, compared with analyst estimates of US$88.5 billion in revenue, according to IBES data from Refinitiv.

The company forecast US$63.0 billion to US$67.0 billion in revenue for the quarter ending in March, ahead of estimates of US$62.4 billion, showing it believes that its phones and other devices such as AirPods wireless headphones will continue to sell well during what is often a slow time of year.

Apple reported services revenue of US$12.7 billion, below analyst estimates of US$13 billion, and up from US$10.9 billion the year before. Many investors think that services revenue eventually will boost Apple's gross margins, which were 38.35 per cent in the December quarter compared with estimates of 38.06 per cent.

The shift toward services, however, depends on Apple continuing to grow its base of users and sign them up for recurring subscriptions that analysts view as potentially more lucrative than hardware sales, which can be inconsistent because they are large purchases that consumers make only every few years. Apple said it now has more than 1.5 billion active installed devices and 480 million subscribers to both its own and third-party paid services, compared with 1.4 billion devices and 360 million subscribers a year earlier.

Cook said the company's Apple TV+ subscription streaming video service released last fall was a "rousing success" and that it is "very strong, both the people that are getting it in the bundle and the people that are paying for it that haven't bought a new device."

Solid iPhone sales of US$55.96 billion compared with analyst estimates of US$51.6 billion and year-before sales of US$52 billion snapped a yearlong trend of major sales declines for Apple's biggest-selling hardware product. Cook said that the iPhone 11 and iPhone 11 Pro models drove the growth and also factored into the company's forecast, calling the devices "the strongest iPhone lineup we've ever had."

But Apple's wearables segment - which, along with AirPods, also includes the Apple Watch - hit US$10.0 billion in revenue versus estimates of US$9.5 billion, up sharply from US$7.3 billion the year before. Bernstein analyst Toni Sacconaghi wrote in a note to clients that sales of AirPods alone - a metric Apple does not disclose - may have reached US$3.5 billion to US$4 billion in the December quarter, a rise of 150 per cent from the year before.

Cook told Reuters that Apple could not make enough AirPods and Apple Watch Series 3 devices to meet demand during the fiscal first quarter and continues to be short on both. Cook said Apple does not have an estimate for when it will be able to fulfill demand for each.

"We're working on both of those very hard," Cook told Reuters.

For the December quarter, Apple reported earnings per share of US$4.99, compared with analyst estimates of US$4.55 per share. For the quarter ending in March, Apple forecast gross margins of between 38.0 per cent and 39.0 per cent, compared with analyst estimates of 38.2 per cent.
