After the close Thursday, Verizon said it had offered to buy IT services provider Terremark for $19 a share in cash, or $1.4 billion.

The offer represents a 35 percent premium over Terremark's closing share price of $14.05 on Thursday. Verizon said it expects to close the tender offer late in the first quarter of 2011.

According to published reports, Verizon said the purchase would assist its efforts to develop cloud-based computing services, or “everything-as-a-service” offerings.
