Retailer TJX Companies Inc., (NYSE: TJX) said on Tuesday that its profit was slightly lower for its fiscal first quarter, hindered by charges related to corporate security breaches.

Net income fell slightly to $161.1 million, or 34 cents per share, compared to $163.8 million, or 43 cents per share in the same period last year.

Massachusetts-based TJX said net sales were up 6 percent to $4.1 billion, while same store sales rose 2 percent. The soft same store sales growth was attributed to unseasonably cold and wet weather in many U.S. regions during March and early April.

Figures were also impacted by $12 million charge related to a computer security break-ins.

The company said in March that information from 45.7 million credit and debit cards was stolen in a computer security breach over 18 months through mid-January.

Other information, including names, addresses and personal ID numbers for about 451,000 people who returned merchandise without a receipt, was also stolen.

Excluding these charges, the company would have earned 37 cents a share.

The company, which operates the T.J. Maxx and Marshalls chains, was expected to report 38 cents per share on revenue of $4.2 billion in revenue.

Shares were down $1.15, or 4.05 percent to $28.37 in Tuesday pre-market trading.
