After a somewhat disappointing Q4 2012, Apple will announce its earnings through the first fiscal quarter of 2013 – but the fourth calendar quarter – on Wednesday, Jan. 23. The Cupertino, Calif.-based tech giant updated its investor page on Wednesday with the new information.

Apple will announce its quarterly earnings, including sales figures from the holidays, iPhone 5 and iPad Mini, among others, shortly after the stock market closes at approximately 4:30 p.m. ET.

“Apple plans to conduct a conference call to discuss financial results of its first fiscal quarter on Wednesday, January 23, 2013 at 2:00 p.m. PT / 5:00 p.m. ET,” the company said.

Apple had its most successful quarter ever this same time last year; one year later, most analysts expect the company to break all of its previous earnings records.

Apple’s Q1 2013 earnings will be the first quarter to include sales from the company’s latest and greatest consumer devices, including the iPhone 5, fifth-generation iPod Touch, seventh-generation iPod Nano, fourth-generation iPad, 13-inch Retina MacBook Pro, newly-updated Mac Mini, redesigned iMac, and first-generation iPad Mini.

Last year, it only took the release of the iPhone 4S, the iPad 2 and the iBooks 2 platform to achieve the most successful quarter in history. Apple claimed $46.33 billion overall, $13.1 billion in profit and $17.5 billion in cash for the quarter ended Dec. 31, 2011.

Apple’s guidance for its Q1 2013 earnings, on the other hand, sets the table for $52 billion in revenue and earnings per diluted share of $11.75. If Apple meets its own expectations, it will easily best its strongest quarter in history.

Apple’s most recent quarter, Q4 2012 ended Sept. 29, was a rare miss for Apple, and one of the only earnings reports to fall below Wall Street’s estimates. Apple reported quarterly fiscal Q4 income of $8.2 billion on $8.67 a share, which was up from $6.62 billion ($7.05 a share) a year ago). Apple’s Q4 2012 earnings did, however, see revenue jump by 27 percent to $36 billion, with the vast majority of that cash flow coming from the iPhone and iPad.

Despite a disappointing fourth quarter, Apple still sold 26.9 million iPhone units and 14 million iPad units; Wall Street predicted 25 million iPhone units sold, but believed the iPad would sell more than 17 million units, which it didn’t. Earnings from Q1 2013 ought to help even those iPad numbers out, given the introduction of the iPad 4 and iPad Mini in October.

Apple’s stock (Nasdaq: AAPL) fell in late-afternoon trading on Thursday, falling from its mid-morning high of $549 a share down to $542 a share.
