NEW YORK ( TheStreet) -- Shares of Radiant Systems ( RADS) jumped in late trades on Monday after the Alpharetta, Ga.-based developer of retailing technology products agreed to be acquired by NCR Corp. ( NCR) for $1.2 billion in cash.

The deal, which has the approval of both companies' boards, is structured as a cash tender offer that values Radiant shares at $28 each, a premium of 30.5% to Monday 's closing price of $21.45, and 38.5% to the 50-day moving average of $20.21.

"Radiant Systems has delivered 15 percent compounded annual revenue growth over the last five years, along with impressive margin expansion as a result of the high customer demand for its expansive software offerings," said Bill Nuti, NCR's chairman and CEO, in a statement. "This acquisition will enable our companies to accelerate expansion through the powerful combination of each other's strengths and NCR's track record of driving transformational change."
