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

10th Consecutive Profitable Quarter

Revenues Increase 20% in Quarter, 45% for the First Nine Months of 2014

EXTON, Pa.—July 29, 2014—Innovative Solutions & Support, Inc. (NASDAQ: ISSC) today announced its financial results for the third quarter of fiscal 2014, ended June 30, 2014.

For the third quarter, the Company reported revenue of $10.6 million, an increase of 20% from revenue of $8.8 million in the third quarter of fiscal 2013. The Company reported third quarter 2014 net income of $497,000, or $0.03 per share, an increase from $307,000, or $0.02 per share, in the same quarter a year ago.  Results for the third quarter of 2013 included a $0.03 per share non-recurring charge related to a previously disclosed legal matter.

Geoffrey Hedrick, Chairman and Chief Executive Officer of Innovative Solutions & Support, Inc. (“ISSC”), said, “Results for the third quarter continue to reflect progress on our engineering development programs.  As third quarter investment in engineering programs declined from the peak in the second quarter, we have been able to advance several development programs to close to completion.  This year, we have begun production deliveries on the Eclipse 550, the KC-46A, the USAF PC-12, and the foreign C-130 full cockpit.  As these programs are completed and the related products are certified, we believe that commercial air transport, military, and general aviation operators will want to capitalize on the significant price for performance advantages of the resulting products.  By leveraging our core technology to develop a

more comprehensive portfolio of products, we are expanding our addressable market and creating value for our shareholders.”

At June 30, 2014, the Company had $14.4 million of cash on hand and no debt. During the third quarter of the current fiscal year the Company used approximately $813,000 of cash to fund operations compared to cash generated by operating activities of $670,000 in the third quarter of fiscal 2013.  The year-over-year change in operating cash reflects primarily differences in the timing of cash expenditures and receipts associated with engineering programs during the quarter.  We expect these differences to reverse as the programs meet contractual billing milestones and/or as production begins.

New orders for the quarter were $2.2 million, and backlog at June 30, 2014 was $72.5 million.  Backlog includes a large contract with Delta Airlines, on which the Company anticipates beginning initial production deliveries later this year.  Backlog excludes potential future sole-source production orders, 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.

Nine Months Results

Revenues for the nine months ended June 30, 2014 were $34.2 million, an increase of 45% compared to $23.5 million for the first nine months of fiscal 2013.  Operating income for the first nine months of fiscal 2014 was $3.2 million, an increase of 68% compared to $1.9 million in the first nine months of fiscal 2013.  Net income was $2.3 million, or $0.13 per share, for the first nine months of fiscal 2014, increases of 32% and 30%, respectively, compared to $1.7 million or $0.10 per share for first nine months of fiscal 2013.

Shahram Askarpour, President of ISSC, commented, “With several of our engineering programs at advanced stages of development, we are focused on completing development and transitioning these programs to full production.   Consequently, engineering revenues have been much higher than normal.  As these high levels of engineering investment begin to decline and production revenues replace them, we expect to generate gross margins more consistent with our historical experience.  Further, as these programs achieve certification and enter production, we anticipate that our price for performance model will continue to generate interest from other potential customers.  As a result of the operational changes that we made earlier this year, the organization is poised to simultaneously execute its development programs, to deliver on production orders, and to continue earning a profit for our shareholders.”

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 as a result of its engineering investments. The Company will provide additional commentary during its earnings conference call.
