Innovative Solutions & Support, Inc. Announces Third Quarter Fiscal 2013

Financial Results

Revenues Grow 43 Percent Year Over Year

Backlog Remains in Excess of $90 million

Exton, PA.  — July 31, 2013 — Innovative Solutions & Support, Inc. (NASDAQ: ISSC) today announced its financial results for the third quarter of fiscal 2013, ended June 30, 2013.

Three Months Results

For the third quarter, the Company reported revenue of $8.8 million, a 43 percent increase compared to third quarter of fiscal 2012 revenues of $6.1 million.  The Company reported third quarter 2013 net income of $307,000, up from $260,000 in the same quarter last year, and earnings per diluted share of $0.02 in both years.  Results for the third quarter of fiscal 2013 reflect a $0.03 per share charge for a previously disclosed non-recurring human resources legal matter.

Geoffrey Hedrick, Chairman and Chief Executive Officer of Innovative Solutions & Support, Inc. (“ISSC”), said, “In the quarter, we announced officially the award of the Utilities Management System (“UMS”) contract for the development and multi-year production in support of the new Pilatus PC-24 business jet.  This Pilatus award represents our third recent Original Equipment Manufacturer (“OEM”) program, each of which will provide ongoing production over a number of years.  Our ‘performance for price’ value proposition continues to create market opportunities for us.  We expect that our current profitability, an increasing backlog, and future production under these OEM contracts will create long term shareholder value.”

Mr. Hedrick added, “The Company continues to grow revenues, profit, and backlog.  Our ongoing investment in product development is key to expanding our revenue and profit.  We are fortunate to have our customers contribute to that investment. The customer contribution is intended to mitigate our substantial engineering development expense of approximately 35% of revenues.  Low margin Engineering Development Contracts (“EDC”) are intended to support our product development, but they have the immediate effect reducing our historical gross margin percentages.”

At June 30, 2013, the Company had $16.6 million of cash on hand, up slightly from $16.3 million at March 31, 2013, although down from a year ago as a result of a special cash dividend of $25 million paid to shareholders in December 2012.  Cash from operating activities was $670,000 in the quarter.  The Company remains free of debt.

At $9.6 million, orders in the third quarter exceeded revenues.  Backlog was $90.9 million at June 30, 2013, compared to $90.1 million at March 31, 2013.  Of the total as of June 30, 2013, $65 million relates to the Delta contract, on which production deliveries are expected to begin in mid-2014 and to extend over several years.  Backlog excludes potential future sole-source OEM production orders for products currently in development under the Company’s EDC’s, including the Eclipse 550, the Pilatus PC-24, and the KC-46A, all of which we expect to be in production over the next several years.

Nine Months Results

Revenues were $23.5 million for the nine months ended June 30, 2013, up 33 percent from $17.7 million for the nine months ended June 30, 2012. For the nine months ended June 30, 2013, net income was $1.7 million or $0.10 per diluted share, compared to net income of $206,000 or $0.01 per diluted share, for the nine months ended June 30, 2012.  The aforementioned third quarter non-recurring legal charge reduced 2013 year-to-date earnings by $0.03 per share.  Cash used in operating activities was $1.6 million for the nine months ended June 30, 2013 compared to positive cash flow from operating activities of $41,000 for the prior year comparable period.

Shahram Askarpour, President of ISSC, commented, “In the third quarter we confirmed our prior selection by Pilatus to provide the UMS for the state-of-the art Pilatus PC-24 business jet.  We had announced the program previously, without identifying Pilatus as the customer, pending its introduction of the program.  This new open architecture UMS represents another milestone toward our goal of becoming a provider of integrated avionics systems.  Over the past two years, we have won

programs with commercial air transport carriers and general aviation aircraft manufacturers, including Delta, Pilatus and Eclipse, and with the U.S. military and foreign militaries.  As a result, our backlog has grown approximately five-fold.  These successes are confirming our ‘performance for price’ product strategy with increasingly price sensitive aircraft owners and operators, and OEM’s.  Although the focus on EDC’s will create short term margin pressure, we expect that these investments will provide years of attractive returns during their production phases.”

Business Outlook

For the full year fiscal 2013, we expect sales to increase approximately 30% over fiscal 2012.  Largely as a result of the impact of the aforementioned non-recurring legal matter, we expect earnings per share to be somewhat below the range of the $0.18 to $0.20 that we had forecast in our second quarter earnings release.  We anticipate that this year’s earnings per share forecast will be an improvement over the fiscal 2012 earnings per share of $0.03 (before the positive effect of a $0.15 per share tax adjustment).  Our anticipated result would represent our fifth consecutive profitable year.

Looking forward to fiscal 2014, we expect sales to increase, with a greater portion of those sales to be related to production.

We will provide additional commentary during our earnings conference call.
