SAIC (NYSE:SAI)
S1/A Filing by the Company
SAIC said today that it would be pricing its shares between $13 and $15 with 75 million shares being issued. The company also revealed that it would be issuing a special dividend of between $1.6 billion and $2.4 billion paid to investors holding prior to the public offering.
