FOR IMMEDIATE RELEASE

Astronics Corporation Reports 2014 Fourth Quarter Sales of $166.1 Million and Net Income of $18.4 Million

EAST AURORA, NY, February 19, 2015 – Astronics Corporation (NASDAQ: ATRO), a leading provider of advanced technologies for the global aerospace, defense, consumer electronics and semiconductor industries, today reported financial results for the fourth quarter and year ended December 31, 2014. Earnings per share for all periods presented are adjusted for the twenty percent distribution of Class B Stock for shareholders of record on September 5, 2014.

Consolidated Review

Fourth Quarter 2014 Results

Consolidated sales increased $60.6 million to $166.1 million, compared with the same period in the prior year. The 2014 fourth quarter included $43.7 million in incremental sales for acquired businesses. Organic sales increased $16.9 million, or 16.1%. Aerospace segment sales increased $25.9 million to $128.6 million and Test Systems segment sales increased $34.7 million to $37.5 million.

Consolidated gross margin was 25.6% compared with 23.9% in the fourth quarter of 2013. Margins expanded on leverage achieved from increased organic sales volume and lower expense related to the fair value step-up of inventory from acquired businesses which was somewhat offset by higher engineering and development (“E&D”) costs. Expense related to the fair value step-up of inventory from acquired businesses was $0.8 million and $3.5 million in the 2014 and 2013 fourth quarters, respectively. E&D costs were $19.7 million, which included $3.8 million for acquired businesses. E&D costs in the prior year’s fourth quarter were $14.3 million.

Selling, general and administrative (“SG&A”) expenses were $17.0 million, or 10.3% of sales, compared with $14.3 million, or 13.5% of sales, in the same period of 2013. Approximately $4.8 million of the increase was associated with acquired businesses, offset by a $4.5 million fair value write-down of the contingent consideration liability related to acquisitions. Additionally, higher SG&A expense reflects increased headcount and compensation costs to support growth.

Diluted earnings per share for the 2014 fourth quarter were $0.81 compared with $0.29 in the prior-year period.

Consolidated 2014 Full Year Review

Consolidated sales in 2014 increased by 94.5%, or $321.1 million, to $661.0 million compared with $339.9 million in 2013. The increase was due to a combination of acquisitions and organic sales volume growth. Acquisitions contributed $270.4 million (comprised of $111.2 million in the Aerospace segment and $159.2 million in the Test Systems segment), while organic sales increased by $50.7 million, or 14.9% from the prior year. On a segment basis, Aerospace sales of $494.7 million were up $164.2 million, while Test Systems sales of $166.3 million increased by $156.9 million compared with the prior year.

Consolidated gross margin was 25.3% in 2014 compared with 25.8% in 2013. Leverage achieved from increased organic sales volume was offset by lower margins from the acquired businesses, which were impacted by higher costs related to the fair value step-up of acquired inventory. Expense related to the fair value step-up of inventory from acquired businesses was $19.4 million and $5.5 million in 2014 and 2013, respectively. Consolidated gross margin was also negatively impacted by increased depreciation expenses of $3.0 million, increased warranty costs of $2.9 million and increased engineering & development (“E&D”) costs. Total E&D costs were $76.7 million for the year, including $19.1 million from acquired businesses. E&D costs in 2013 were $52.8 million.

Selling, general and administrative (“SG&A”) expenses were $79.7 million, or 12.1% of sales, compared with $45.6 million, or 13.4% of sales, in the prior year. The increase was due primarily to $34.8 million in incremental SG&A costs of acquired businesses, including $10.4 million of incremental amortization expense for acquired intangible assets. Additionally, higher SG&A expense reflects increased headcount and compensation costs to support growth. SG&A expenses in 2014 were positively affected by the $5.0 million fair value write-down of a contingent consideration liability related to acquisitions.

Diluted earnings per share for 2014 were $2.48 compared with $1.24 in the prior year. In 2014, fair value inventory step-up charges associated with acquired businesses’ inventory was approximately $19.4 million before taxes, or approximately $0.58 per diluted share after tax.

Aerospace Fourth Quarter 2014 Results

Aerospace segment sales increased by $25.9 million, or 25.3%, to $128.6 million when compared with the prior year’s fourth quarter. Organic sales grew 16.8%, or $17.2 million, and sales from acquired businesses added $8.7 million.

Sales to the Commercial Transport market increased $27.1 million, of which approximately $6.5 million was related to the acquired businesses with the remaining increase primarily related to higher organic sales of Electrical Power & Motion and Avionics products. Organic sales of Electrical Power & Motion products to the Commercial Transport market increased approximately $10.0 million. Organic sales of Avionics products to this market increased by $7.8 million.

Military sales decreased $4.4 million when compared with the prior year, due primarily to general reduction of volumes.

Aerospace operating profit for the fourth quarter of 2014 was $19.4 million, or 15.1% of sales, compared with $14.1 million, or 13.7% of sales, in the same period last year. Approximately $1.2 million in incremental operating profit was related to the acquired Aerospace businesses. Operating leverage gained on higher volume for the organic business was partially offset by approximately $1.7 million of higher organic E&D costs and $1.4 million of costs related to the write down of assets used exclusively on the paused Learjet 85 program.

Aerospace 2014 Results

Sales for the Aerospace segment increased $164.2 million in 2014 compared with the prior year. Organic sales grew 16.0%, or $53.0 million. Incremental sales from acquired businesses were $111.2 million.

The $3.1 million increase in 2014 to other markets reflected approximately $4.6 million from acquired businesses offset by a $1.5 million decline in organic sales.

Aerospace operating profit for 2014 was $79.8 million, or 16.1% of sales, compared with $55.2 million, or 16.7% of sales, in the prior year. The acquired businesses contributed approximately $9.4 million in incremental operating profit in 2014. Leverage achieved from higher organic sales volume was partially offset by increased organic E&D costs of approximately $5.0 million and an increase in organic warranty costs of $2.3 million. Additionally impacting Aerospace operating margins was expense related to the fair value step-up of inventory from acquired businesses of approximately $2.6 million and $5.5 million in 2014 and 2013, respectively. Aerospace SG&A expense increased $19.4 million in 2014 compared with 2013. The increase was

due primarily to the incremental SG&A of acquired businesses, which added $16.7 million, including $4.4 million of acquired intangible asset amortization expense.

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

Test Systems Fourth Quarter 2014 Results

Test Systems sales increased $34.7 million to $37.5 million compared with sales of $2.8 million for the same period in 2013. Astronics Test Systems (“ATS”), acquired on February 28, 2014, contributed $35.0 million in sales to both the Commercial Electronics and Military markets. Operating profit for the fourth quarter of 2014 was $4.4 million compared with an operating loss of $0.9 million in the same period last year. The improvement was a result of the operating profit from ATS. Test Systems fourth quarter operating profit was negatively impacted by $0.8 million in expense for the fair value step-up of acquired inventory. Additionally, amortization expense in the fourth quarter relating to the acquisition was $0.6 million.

Test Systems 2014 Results

Sales in 2014 increased $156.9 million to $166.3 million compared with sales of $9.4 million for 2013. Incremental sales to both the Commercial Electronics and Military markets from the acquisition of ATS drove the growth. Sales from this acquired business were $159.2 million in 2014; organic Test System sales were $7.1 million for 2014.

Operating profit for 2014 was $12.4 million compared with an operating loss of $3.8 million for 2013. All of the improvement was due to the margin provided by the ATS acquisition. Included in 2014 cost of products sold was $16.8 million of expense related to the fair value step-up of acquired inventory. Incremental SG&A and E&D costs included in cost of products sold of the acquired business were approximately $18.2 million and $9.1 million, respectively.

Forecast

We expect consolidated sales in 2015 to be between $680 million and $740 million, including the January 2015 addition of Armstrong Aerospace, Inc. Our consolidated backlog at December 31, 2014 was $370.7 million, of which approximately $321.8 million is expected to ship in 2015.

We expect our capital equipment spending in 2015 to be in the range of $20 million to $25 million, excluding Armstrong. E&D costs are estimated to be in the range of $75 million to $80 million, excluding Armstrong. Approximately $550 million to $580 million of forecasted 2015 revenue is expected from the Aerospace segment, while approximately $130 million to $160 million of the forecasted revenue is expected from the Test Systems segment.

Mr. Gundermann commented, “2014 was a strong year of growth for Astronics, with revenue and profits essentially doubling from 2013. These types of results do not come easily and are a tribute to our dynamic team of employees who have made it happen. We expect our momentum to continue into 2015, which should be another very good year for the company.”
