SAN FRANCISCO — Shortly after Apple used a  new tax law last year to bring back most of the $252 billion it had  held abroad, the company said it would buy back $100 billion of its  stock.
On Tuesday, Apple announced its plans for another major chunk of the money: It will buy back a further $75 billion in stock.
“Our first priority is always looking after the business and making  sure we continue to grow and invest,” Luca Maestri, Apple’s finance  chief, said in an interview. “If there is excess cash, then obviously we  want to return it to investors.”
Apple’s record buybacks should be welcome news to shareholders, as  the stock price is likely to climb. But the buybacks could also expose  the company to more criticism that the tax cuts it received have mostly  benefited investors and executives.
Separately on Tuesday, Apple said slumping iPhone sales shrank its  profit 16.4 percent, to $11.56 billion, in the latest quarter compared  with a year ago.
In the period, the company’s second fiscal quarter, iPhone sales fell  17.3 percent from the same period a year ago, to $31 billion, in part  because of a larger drop in revenue in the China region. The company’s  services revenue, which includes app sales, grew 16.2 percent to $11.45  billion.
Overall results exceeded Wall Street’s expectations and Apple’s share  price rose about 5 percent in after-hours trading. Investors had  anticipated a slowdown in iPhone sales but some signs suggested business  was rebounding.
Timothy D. Cook, Apple’s chief executive, said on a call with  analysts that business in China increased toward the end of the quarter.  He attributed the improvement partly to price cuts, the Chinese  government’s economic stimulus, and loosening trade tensions with the  United States.
Apple said it expected revenue for the current quarter would be $52.5  billion to $54.5 billion, exceeding analysts’ forecasts. The company  also announced a 5 percent increase to its dividend.
While stock buybacks have plenty of critics, many economists say the  money is better off flowing into investors’ pockets and into the economy  instead of sitting in Apple’s coffers.
“The money isn’t disappearing,” said Alan Auerbach, an economics and  law professor at the University of California, Berkeley. “Apple is  basically saying: We have all this money and we prefer not to invest it  right now, so we’ll give it to our shareholders.”
Still, Apple’s decision to return so much cash to investors is likely  to provide more grist for liberal politicians who argue that giant  stock buybacks are manipulations of the stock market.
Sens. Chuck Schumer, the Democratic Senate leader, and Bernie  Sanders, I-Vt., a presidential candidate, recently proposed restricting  such buybacks, saying they increase inequality by putting billions of  dollars in the pockets of wealthy shareholders instead of into new  plants and higher wages.
“It’s total insanity,” said Ralph Nader, the consumer advocate and  former presidential candidate. “The main incentive, which they will not  admit to, is it improves the metrics for executive compensation that  consultants develop for them.”
Nader and other corporate critics say Apple could spend a small  fraction of the $75 billion it plans to give to investors on a way to  effectively recycle the world’s computer waste, cut the prices of  iPhones that have swelled past $1,000, or increase the pay of its  contract workers in China. Apple has said the starting pay for workers  at the world’s biggest iPhone factory, in Zhengzhou, China, is about  $3.15 an hour.
But some economists say that thinking is simplistic: Corporations  aren’t the government and shouldn’t be expected to invest large sums in  ventures that won’t contribute to profits.
“Firms should reinvest internally when it’s their best use of  capital, and they should pay it out to investors when it’s not,” said  Laurie Hodrick, a visiting finance professor at Stanford University who  studies how corporations use their cash.
Maestri, Apple’s finance chief, said Apple invested an appropriate  amount in its business before deciding how much to return to  shareholders. During the past two quarters, Apple’s spending on research  and development increased 15.7 percent to $7.85 billion. “Certainly  making investments that are not productive are not good for anybody,” he  said.
When it repatriated its cash under the new tax law, Apple paid $43  billion less than it would have under previous rates, bigger savings  than any other American company, according to the Institute on Taxation  and Economic Policy, a research group in Washington. Apple has also  saved billions of dollars under the lower corporate tax rate. Apple says  it is spending billions in the United States, hiring new workers,  building data centers, expanding offices in Texas and investing in some  outside manufacturers.
For many big companies like Apple, stock buybacks also support higher  compensation for employees, since so many of them are paid in part with  company stock, said Ed Yardeni, president of the stock market research  firm Yardeni Research.
Companies in the S&P 500 bought back a record $806 billion in  stock last year, up from $519 billion in 2017, according to data from  Howard Silverblatt, senior index analyst for S&P Dow Jones Indices.
Apple has returned the largest amounts to shareholders in history,  Silverblatt said. From 2014 through 2018, Apple bought back $229 billion  in stock, or more than the value of Home Depot, the 18th most valuable  company in the S&P 500 index.
During that period, Microsoft was second in stock buybacks, with $66  billion, according to Silverblatt. Apple accounted for seven of the  eight largest quarterly stock buybacks in history, including the latest  quarter, Silverblatt said.
