NEW YORK (

TheStreet

) -- Shares of

Red Hat

(RHT) - Get Report

fell in late trades on Monday despite a 2-cent profit beat from the Raleigh, N.C.-based open-source software company in its latest quarter.

After the close, Red Hat posted non-GAAP earnings of $55.7 million, or 28 cents a share, on revenue of $290 million for the three months ended Nov. 30. The average estimate of analysts polled by

Thomson Reuters

was for a profit of 26 cents a share on revenue of $289.6 million in the quarter.

The in-line revenue performance looks disappointing though given that Red Hat had come in at least $10 million above consensus in the previous two quarters.

"We continued to deliver consistent performance across our business which resulted in strong growth in our key financial metrics. At the same time, we continued to invest in strategic growth initiatives," said Charlie Peters, the company's chief financial officer, in a statement. "When compared to the first three quarters of last fiscal year, our year-to-date revenue, non-GAAP operating income and operating cash flow are up 26%, 35% and 35%, respectively."

On its conference call, the company said it expects earnings of 26 to 27 cents a share with revenue ranging from $289 million to $292 million for its fiscal fourth quarter ending in February. Wall Street's current consensus view is for a profit of 26 cents a share in the quarter on revenue of $292.5 million in the period.

For its full fiscal year, Red Hat now sees earnings of $1.07-$1.08 per share. The average analysts' view sits at a profit of $1.05 a share.

Shares were last quoted at $42.81, down 7%, on volume of around 800,000. The stock is flat in the past year but had already declined 14% based on Monday's regular session close at $46.05 since hitting a 52-week high of $53.42 on Nov.16.

AT&T

Shares of

AT&T

(T) - Get Report

slumped in the extended session after the Dow component said it's dropping its bid to acquire

T-Mobile

.

The transaction, which valued T-Mobile at $39 billion, was sidelined by the anti-trust concerns of U.S. regulators, who argued the combination would lead to less choice and higher prices for consumers.

As a results of scrapping the deal, AT&T said it expects to record a pre-tax charge of $4 billion in its fiscal fourth quarter to reflect a break-up fee being paid to

Deutsche Telekom

, the parent company of T-Mobile.

AT&T also said it's entering a "mutually beneficial" roaming agreement with Deutsche Telekom but didn't provide further details on terms.

The company criticized regulators in its press release announcing the decision.

"The actions by the Federal Communications Commission and the Department of Justice to block this transaction do not change the realities of the U.S. wireless industry," AT&T said. "It is one of the most fiercely competitive industries in the world, with a mounting need for more spectrum that has not diminished and must be addressed immediately. The AT&T and T-Mobile USA combination would have offered an interim solution to this spectrum shortage. In the absence of such steps, customers will be harmed and needed investment will be stifled."

AT&T shares were last quoted at $28.67, down 7 cents, on volume of more than 850,000, according to

Nasdaq.com

.

S&P Capital IQ maintained its strong buy on AT&T following the news, and said the "mutually beneficial" roaming agreement that the company entered with T-Mobile is a positive and could "alleviate some of the needed spectrum."

"While the breakup fee and resources tied to the deal is unfortunate, we believe T's strong 6M smartphone sales in October and November is sign of execution," S&P Capital IQ said. "We expect capex to remain focused on wireless, but remain manageable. We still see T as undervalued and supported by recent dividend hike."

AT&T announced a 2%-plus boost to its dividend on Friday, and the stock's forward annual yield sits about 6%.

The news boosted shares of a number of other telcos in late action, including

Clearwire

(CLWR)

, a wireless broadband company, whose stock was up more than 6% to $2.16 on volume of nearly 400,000;

Sprint Nextel

(S) - Get Report

, whose shares rose 5.5% to $2.28 on volume of 1.3 million; and

Verizon

(VZ) - Get Report

, which edged up 8 cents to $38.71 on volume of more than 400,000.

Bank of America

The other bit of drama in the extended session was provided by

Bank of America

(BAC) - Get Report

, which

closed regular trading at $4.99

, down more than 4%, making it the biggest percentage decliner in the

Dow Jones Industrial Average

on Monday.

The selling pressure was in part a product of the rising fears about Europe's stability, but the proximity of Bank of America's share price to $5 was also a factor as many fund managers aren't able to invest in stocks that drop below that threshold. Monday's finish was the stock's worst since March 2009 when the markets were still in the throes of the financial crisis.

Bank of America's stock edged up to $5.01 in after-hours action with 8.6 million shares changing hands, according to

Nasdaq.com

. The shares dipped as low as $4.92 in the regular session. A majority of the sell side is bearish on the bank with 18 of the 32 analysts rating the stock at either hold (17) or underfperform (1).
