Today, Advanced Photonix Inc. and Luna Innovations Incorporated jointly announced an update as to the timing of their planned merger.    As previously disclosed, the closing of the proposed merger is subject to the satisfaction or waiver of a number of customary closing conditions, including, among others, the effectiveness of a Form S-4 registration statement filed by Luna with the SEC and the approval of certain matters related to the merger by each company’s stockholders.  In February, Luna filed a Form S-4 registration statement with the Securities and Exchange Commission with respect to the proposed merger.   However, that registration statement is not yet effective, and the companies have yet to finalize the dates of their respective stockholders meetings.  Luna expects to file an amendment to the Form S-4 in March 2015 and, following the effectiveness of the Form S-4, Luna and Advanced Photonix will mail the joint proxy statement/prospectus included in the Form S-4 to their stockholders for consideration at their respective stockholder meetings.  Although the companies have not yet formally determined the dates of their stockholder meetings, the companies currently expect to hold their meetings, and close the merger, in May 2015.
