Amicas Inc., which provides health care information technology services, said Monday it agreed to be acquired by private equity firm Thoma Bravo LLC in a deal worth about $217 million in cash.
Under terms of the agreement, Amicas shareholders will receive $5.35 in cash for each share or stock option they hold.
That represents a 21 percent premium to the stock's Thursday closing price of $4.42 ahead of the holiday weekend. The stock rose $1.23, or 27.8 percent, to $5.65 during premarket trading Monday. Shares have ranged from $1.47 to $4.84 over the past year.
The deal is expected to close in the first quarter of 2010.
Amicas can solicit alternative proposals from third parties for 45 days beginning Dec. 24.
