FOR IMMEDIATE RELEASE

Astronics Corporation Reports 2014 First Quarter Results

EAST AURORA, NY May 7, 2014 – Astronics Corporation (NASDAQ: ATRO), a leading provider of advanced technologies for the global aerospace and defense industries, today reported financial results for the three months ended March 29, 2014.

Peter J. Gundermann, President and Chief Executive Officer, commented, “Our first quarter results were strong, reflecting solid conditions in the industry, double digit organic growth and positive contributions from our recent acquisitions. Results are especially notable when one considers that we incurred about $8.7 million of fair value inventory step-up expense relating to acquisition accounting during the quarter. Our acquisitions, including Astronics Test Systems which we acquired in February, are performing collectively to plan and have helped us get off to a great start for 2014.”

Consolidated Review

First Quarter 2014 Results

Consolidated sales for the first quarter of 2014 increased by 90.6% to $141.0 million compared with $74.0 million for the same period last year. Aerospace sales increased by $50.7 million and Test Systems sales increased by $16.3 million. From July 2013 through the end of the 2014 first quarter, Astronics completed four business acquisitions, three in its Aerospace segment and one in the Test Systems segment. Acquisitions contributed $58.8 million to consolidated sales, while organic sales increased $8.2 million, or 11.0%.

Consolidated gross margin was 21.3% in the first quarter of 2014 compared with 27.3% in the first quarter of 2013. Margin leverage achieved from increased organic sales volume was more than offset by costs of approximately $8.7 million relating to the fair value step-up of inventory from acquired businesses and increased engineering and development (“E&D”) costs in Astronics organic businesses of approximately $1.2 million. Total E&D costs were $17.3 million in the first quarter of 2014 including $3.2 million for businesses acquired since the first quarter of 2013. Last year’s first quarter had $12.8 million in E&D expense.

Selling, general and administrative (“SG&A”) expenses were approximately $16.4 million, or 11.6% of sales in the first quarter of 2014 compared with $9.2 million, or 12.4% of sales in the same period last year. The increase was due primarily to the incremental SG&A costs of acquired businesses, which added approximately $7.0 million to SG&A in the first quarter of 2014 when compared with the prior year first quarter.

Diluted earnings per share for the 2014 first quarter were $0.40 compared with $0.47 in the prior year period. This includes the impact of fair value inventory step-up charges for inventory of acquired businesses, which totaled approximately $8.7 million before taxes, or approximately $0.30 per diluted share after tax in the first quarter of 2014.

Earnings per share for all periods presented have been calculated reflecting the effect of the one-for-five Class B share distribution for shareholders of record on October 10, 2013.

Aerospace Segment Review (refer to sales by market and segment data in accompanying tables)

Aerospace First Quarter 2014 Results

Aerospace segment sales increased by $50.7 million, or 70.7%, compared with the prior year’s first quarter. Organic sales grew 12.6%, or $9.1 million, and sales from acquired businesses added $41.6 million. Sales to the Commercial Transport market increased due primarily to the sales contributed by the acquired businesses of approximately $35.6 million. Additionally, sales of Electrical Power & Motion products excluding acquired businesses increased approximately $12.1 million as global demand for passenger power systems continued to be strong. Military sales were up slightly when compared with the prior year’s first quarter as sales contributed by the acquired businesses added $1.0 million and was partially offset by lower organic sales to the Military market. Sales to the Business Jet market were up when compared with last year’s first quarter due primarily to the sales contribution from acquired businesses of $2.7 million which was partially offset by a decrease of organic sales of $1.5 million as Lighting & Safety and Electrical Power & Motion sales both decreased slightly. The increase in first quarter Other sales was due primarily to sales from the acquired businesses of approximately $2.3 million partially offset by decreased organic Other sales of $1.4 million.

Aerospace operating profit for the first quarter of 2014 was $17.5 million, or 14.3% of sales, compared with $14.3 million, or 19.9% of sales, in the same period last year. The margin leverage achieved from increased organic sales volume was offset by increased depreciation and amortization expense of $2.8 million and increased organic E&D costs of approximately $1.3 million. Additionally, cost of products sold was approximately $2.4 million greater due to the lower margins

recognized from the sale of inventory written up to fair value at the time of acquisition for the acquired businesses. Aerospace SG&A expense increased $5.7 million in 2014 as compared with 2013. The increase was due to the incremental SG&A for the acquired businesses.

Test Systems Segment Review (refer to sales by market and segment data in accompanying tables)

Test Systems First Quarter 2014 Results

Sales in the 2014 first quarter increased approximately $16.3 million to $18.6 million when compared with sales of $2.3 million for the same period in 2013, due primarily to the incremental sales to both the Commercial Electronics and Military markets that was provided by the acquisition of ATS on February 28, 2014. ATS contributed $17.2 million in sales which was partially offset by decreased sales of our organic Test Systems business of approximately $0.9 million.

Test Systems operating loss for the first quarter of 2014 was $1.7 million compared with an operating loss of $1.5 million in the same period last year. The operating loss in the first quarter of 2014 includes $6.3 million in cost of products sold that is related to the fair value step-up of inventory from acquired businesses. Depreciation and amortization expense relating to the acquisition was $0.2 million in the first quarter of 2014.

Balance Sheet

Cash at the end of the first quarter of 2014 was $29.1 million compared with $54.6 million at December 31, 2013. Cash provided by operating activities in the first quarter of 2014 was approximately $2.6 million.

Cash used for investing activities was $87.2 million. This included $14.9 million for the purchase and modifications of a new building in Oregon and the acquisition of ATS for $70.3 million. The Company expects capital spending in 2014 to be in the range of $33 million to $37 million, including the purchase and modifications of the new Oregon building.

Outlook

On March 31, 2014, backlog was a record $362.4 million, improved from $214.2 million at the end of the trailing fourth quarter of 2013 and $119.0 million at the end of the first quarter of 2013. Approximately $324.1 million of this backlog is expected to ship over the balance of 2014.

The Company has raised its expectations for 2014 revenue to be in the range of $625 million to $660 million from its previous expectation of $585 million to $640 million. Astronics anticipates that approximately $480 million to $505 million of forecasted 2014 revenue will be from its Aerospace segment, while approximately $145 million to $155 million of the forecasted revenue will be from its Test Systems segment.

Mr. Gundermann concluded, “We had record bookings in the first quarter of $146 million, an increase of 34% over our previous high. This gave us a record backlog as we entered the second quarter and put us in a good position to execute our plan for the remainder of the year.

The midpoint of our new range for 2014 would suggest revenue increasing almost 90% over last year, which would obviously be a very strong year for our company.”
