For the fiscal year ended March 31, 2016, the Company reported revenues of $103.0 million as compared with revenues of $126.8 million for the prior fiscal year, a net loss of $3.2 million, inclusive of $3.1 million of charges (equal to $0.26 earnings per share) related to the corporate realignment and cost containment actions which occurred in fiscal year 2016, compared with net income of $1.0 million for the prior fiscal year, and a loss per share of $0.45 as compared with earnings per share of $0.13 for the prior fiscal year.

The Company reported $24.0 million in bookings for the fourth quarter of fiscal year 2016 as compared with $31.3 million in bookings for the fourth quarter of the prior fiscal year, and $121.0 million in bookings for the fiscal year ended March 31, 2016 as compared with $89.6 million in bookings for the prior fiscal year, representing a 35% increase.

“We achieved strong year-over-year increases in bookings and backlog and returned to positive free cash flow in fiscal year 2016,” commented Chuck Dougherty, AS&E’s President and Chief Executive Officer. “Organic investment has enabled us to complete an extensive revitalization of our product portfolio to expand the application reach of our technology and strengthen our family of solutions by leveraging multiple, complementary technologies.”

Dougherty continued, “Although external factors continued to adversely impact our results throughout the year, we responded by reducing operating expenses to align with the size and composition of the business. We believe that these cost containment actions — combined with the growth in bookings, the strength of our backlog, and our revitalized product and services portfolio — position us well to return to profitability as we enter fiscal year 2017. We remain committed to enhancing shareholder value and improving our results by managing operating costs and

monitoring the global business environment as we continue to drive execution of our strategic initiatives.”

The Company’s Board of Directors has declared a quarterly cash dividend of $0.50 per share, payable on June 1, 2016 to the holders of record of the Company’s common stock at the close of business on May 23, 2016.  The Company paid a quarterly dividend of $0.50 per share throughout fiscal year 2016.
