Innovative Solutions & Support, Inc. Announces Second Quarter Fiscal
2014 Financial Results

Sales up 52% from year ago

EXTON, Pa.—April 23, 2014—Innovative Solutions & Support, Inc. (NASDAQ: ISSC) today announced its financial results for the second quarter of fiscal 2014, ended March 31, 2014.

For the second quarter of fiscal 2014, the Company reported sales of $12.5 million, a 52 percent increase compared to sales of $8.2 million for the second quarter of fiscal 2013. The Company reported second quarter 2014 net income of $0.8 million, or $0.05 per diluted share, compared to second quarter 2013 net income of $1.1 million, or $0.07 per diluted share.

Geoffrey Hedrick, Chairman and Chief Executive Officer of Innovative Solutions & Support, Inc. (“ISSC”) said, “Sales, margins and profits continue to be consistent with our goals for fiscal 2014.  We are pleased with the growth of our production sales, which are generating gross margins similar to our historical experience of approximately 50%.”  Quarterly engineering sales were a record $4.4 million.

At March 31, 2014, the Company had $15.3 million of cash on hand and remained debt-free.  Cash used in operating activities for the quarter was $585,000 compared to cash used of $222,000 in the first quarter of fiscal 2014.

Net orders for the quarter were $6.7 million, and backlog at March 31, 2014 was $80.9 million. The backlog includes a large contract with Delta Airlines, on which the Company anticipates beginning initial production deliveries this fiscal year. Backlog excludes potential future sole-source production orders from products in development under the Company’s engineering development contracts, including the Eclipse 550,

the Pilatus PC-24, and the KC-46A, all of which the Company expects to remain in production for a decade following completion of their development phases. The Company expects that these sole-source contracts will add to production sales already in backlog.

Six Months Results

Total sales for the six months ended March 31, 2014 were $23.6 million, up 59 percent year over year.  Production sales for the six months ended March 31, 2014 were $15.8 million, up 36% from the comparable prior year period.  Net income for the six months ended March 31, 2014 was $1.8 million, up 29% compared to $1.4 million year over year.  Earnings per share for the six months ended March 31, 2014 were $0.10 per diluted share, up 11%, compared to $0.09 per diluted share for the first half of the last fiscal year.

Shahram Askarpour, President of ISSC, commented, “We are pleased with our overall performance and with the growth of our production volumes as certain engineering development programs begin to transition to production.  The Eclipse program is now in production, and we expect the Delta program to enter production later this year.  In anticipation of the sales growth, we have strengthened our organization to complete our engineering development program milestones and to manage the growth in production.”

Mr. Hedrick concluded, “The increase in production volumes of existing products and the progress in the development of new products are evidence of the success of our price-for-performance strategy.  Consequently, we intend to continue engineering investments, which totaled in excess of 35% of sales in the first six months of this fiscal year, so that we can offer a growing portfolio of both OEM and retrofit flight management systems, GPS sensors, and other NextGen air traffic control products to the commercial air transport, military and general aviation markets.”

Business Outlook

For the fiscal year ending September 30, 2014, IS&S expects to increase sales, operating income, and net income compared to fiscal 2013 and to report its sixth consecutive profitable year, characterized by growing production volume resulting from its engineering investments.  The Company will provide additional commentary during its earnings conference call.
