Merger of Luna and API is approved

Combined company has stronger market and financial position ROANOKE, VA, (May 11, 2015) – Luna Innovations Incorporated (NASDAQ: LUNA), which develops and manufactures fiber optic sensing and test & measurement products for the telecommunications, aerospace, automotive, energy, and defense markets and Advanced Photonix, Inc., a leading supplier of optoelectronic sensors, devices, and instrumentation for the telecommunications, defense, medical, and industrial markets announced on Friday that they have completed their merger.  In their annual meeting on Friday, May 8, 2015, Luna’s stockholders approved the issuance of 0.31782 shares of Luna common stock to API stockholders for each share of their API common stock. API’s stockholders approved the merger in a separate special API stockholder meeting.  The merger received overwhelmingly positive response from stockholders, with over 99% of Luna’s voting stockholders and over 98% of API’s voting stockholders supporting the transaction. “This merger has created a company with a stronger position as a leader in optical technology and provides improved opportunities for accelerated growth,” said Luna president and CEO My Chung. “We look forward to working with the talented team at API as we build a dynamic company with even greater potential.” The merger essentially doubles the revenue base of each of the companies stand-alone, provides the opportunity to leverage a shared infrastructure and achieve significant cost savings by combining two public companies into one. The company will build from a strong foundation of products - Luna’s core Test & Measurement products, and API’s High Speed Optical Receivers and Optosolutions products. The combined product lines will strengthen the merged company’s position in the marketplace by offering more for each customer, creating a significantly stronger company. This solid combined revenue base will enable continued investment in each of their identified growth opportunities- Luna’s strain & temperature sensing business and API’s Terahertz sensing systems. Additionally, their contract research and engineering teams will continue to develop a pipeline of new technologies for future commercialization. In connection with the Merger, Luna also entered into a new $6 million term debt agreement with Silicon Valley Bank (“SVB”).  The new four year term debt replaces all of the outstanding loans of API and Luna prior to the completion of the Merger.  The new loan is to be repaid in 48 monthly installments, bears interest at the rate of prime plus 2%, is secured by substantially all of the company’s assets, and is subject to customary covenants, including the maintenance of certain minimum liquidity ratios. Luna will keep its headquarters in Roanoke, VA, moving into its newly renovated downtown space in the Parkway 301 Building.  My E. Chung continues as president and CEO of the combined company and a member of the board of directors. The board of directors has been expanded to seven seats composed of Richard W. Roedel as chairman, John B. Williamson III, Michael W. Wise, Donald Pastor, Gary J. Spiegel and Ed J.
