After months of delay, the $13.5 billion merger of

Symantec

(SYMC) - Get Report

and

Veritas Software

(VRTS) - Get Report

will be voted on -- and almost certainly approved -- by shareholders on June 24.

Late Thursday, the companies announced that the last bit of red tape --

Securities and Exchange Commission

approval of the companies' joint proxy statement -- had been removed.

If approved by shareholders, the companies will merge by the end of June or early July.

The merger was announced in December and hasn't been well-received on Wall Street. Analysts are concerned that Veritas could slow Symantec's torrid growth rate, and they wonder if there will be constructive synergies between two very different companies -- a security software vendor and a maker of storage management software.
