SEATTLE - Apple Inc. said Monday that net income for the most recent quarter soared 70 per cent on strong sales of iPhones, though iPad sales fell short of expectations.

Shares fell in after-hours trading. Apple's stock had been breaking through record-high prices for more than a week on high hopes for the iPad.

Apple sold 4.2 million of its new tablet-style computer during the fiscal fourth quarter, fewer than the approximately 5 million that analysts, on average, had expected.

The company sold 14.1 million iPhones from July through September, more than the 12 million or so analysts were looking for. Apple Chief Financial Officer Peter Oppenheimer said in an interview that had the company been able to make more iPhones, that number would have been even higher.

Sales of the iPad might have been constrained by supply issues. Oppenheimer said the company was able to increase production of the iPad toward the end of the quarter.

Apple's net income rose to $4.3 billion, or $4.64 per share, from $2.5 billion, or $2.77 per share, in the same period last year.

Revenue jumped 67 per cent to $20.3 billion from $12.2 billion last year.

Both revenue and net income were record amounts for Apple. The company also did significantly better than Wall Street analysts expected. Analysts polled by Thomson Reuters expect Apple to earn $4.08 per share on $18.9 billion in revenue.

"When you're shipping the best products ever, these are the results you expect to see," Oppenheimer said.

Shares of Apple, which is based on Cupertino, Calif., plunged $20.69, or 6.5 per cent, to $297.31 in extended trading after the release of results. In the regular session earlier, the stock rose $3.25, or 1 per cent, to $317.99.

For the full fiscal year, Apple's net income jumped 70 per cent to $14 billion, or $15.15 per share, from $8.2 billion or $9.08 per share.

Revenue jumped 52 per cent to $65.2 billion from $42.9 billion.
