FOR IMMEDIATE RELEASE

Astronics Corporation Reports 2015 Second Quarter Sales of $173.2 Million and Net Income of $17.7 Million

EAST AURORA, NY, August 5, 2015 – Astronics Corporation (NASDAQ: ATRO), a leading supplier of products to the global aerospace, defense, consumer electronics and semiconductor industries, today reported financial results for the second quarter and six months ended July 4, 2015.

Peter J. Gundermann, President and Chief Executive Officer, commented, “Astronics performed well with second quarter sales and earnings both among our best ever. Our Aerospace Segment continued to show solid overall growth and our Test Segment was nicely profitable despite reduced volume compared to last year.”

Consolidated Review

Second Quarter 2015 Results

Consolidated sales for the second quarter of 2015 were $173.2 million, down slightly from $174.6 million for the same period last year as strength in Aerospace sales helped to offset lower Test Systems segment sales. The 2015 second quarter included $7.1 million in sales from Armstrong Aerospace, Inc. (“Armstrong”), acquired on January 14, 2015. Organic sales for the quarter decreased $8.5 million, or 4.9%, on lower Test System segment sales.

Consolidated gross margin was 28.6% in the second quarter of 2015 compared with 24.7% in the second quarter of 2014. The second quarter of 2014 included $8.7 million of inventory fair value step-up expense of acquired businesses compared with $0.1 million in the second quarter of 2015. Engineering and development (“E&D”) costs were $21.3 million in the second quarter of 2015, including $1.6 million for Armstrong. E&D costs in last year’s second quarter were $20.7 million. As a percent of sales, E&D was 12.3% and 11.9% in the second quarters of 2015 and 2014, respectively.

Selling, general and administrative (“SG&A”) expenses were $21.3 million, or 12.3% of sales, in the second quarter of 2015 compared with $20.7 million, or 11.9% of sales, in the same period last year. The increase was due primarily to the incremental SG&A costs of Armstrong, which added approximately $1.6 million to SG&A in the second quarter of 2015, including $0.7 million of amortization expense for acquired intangible assets of that business.

Diluted earnings per share for the 2015 second quarter were $0.77 compared with $0.58 in the prior-year period, an increase of 32.8%.

First Half 2015 Results

Consolidated sales for the first six months of 2015 increased by $19.3 million, or 6.1%, to $334.8 million from $315.5 million for the same period last year. The acquisition of Armstrong contributed $13.8 million to consolidated sales, while consolidated organic sales increased $5.5 million, or 1.7%.

Consolidated gross margin was 26.8% in the first six months of 2015 compared with 23.2% in the first six months of 2014. The first six months of 2014 included $17.4 million of inventory step-up expense compared with $0.7 million in the first six months of 2015. E&D costs were 13.0% of sales, or $43.6 million, which included $3.0 million for Armstrong, compared with $37.9 million, or 12.0% of sales, in the prior year’s first six months.

Selling, general and administrative (“SG&A”) expenses were $43.9 million, or 13.1% of sales, in the first six months of 2015 compared with $37.1 million, or 11.8% of sales, in the same period last year. The increase was due primarily to the incremental SG&A costs of Astronics Test Systems, Inc. (“ATS”, acquired on February 28, 2014) and Armstrong, which collectively added approximately $4.4 million to SG&A in the first six months of 2015, including $1.7 million of amortization expense for acquired intangible assets of those businesses. Additionally, higher SG&A expense reflected increased headcount and compensation costs to support growth.

Diluted earnings per share for the first six months of 2015 were $1.24 compared with $0.91 for the same period last year, an increase of 36.3%.

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

Aerospace Second Quarter 2015 Results

Aerospace segment sales increased by $10.6 million, or 8.8%, when compared with the prior year’s second quarter to $132.2 million. Organic sales grew 2.9%, or $3.5 million, and sales from Armstrong added $7.1 million. Sales in the 2015 second quarter were the Company’s second highest, following the first quarter of 2015.

Sales to the Commercial Transport market increased $11.1 million, of which $7.1 million was related to the acquisition of Armstrong, primarily comprised of Systems Certification sales. The remaining increase was primarily higher sales of Electrical Power & Motion products, which increased $8.0 million, or 13.9%, partially offset by lower sales of Avionics products. Sales of Avionics products to the Commercial Transport market decreased by $2.6 million. Sales to the Military market decreased $1.8 million when compared with last year’s second quarter. Sales to the Business Jet market increased $0.8 million compared with the same period last year.

Aerospace operating profit for the second quarter of 2015 was $20.3 million, or 15.3% of sales, compared with $20.8 million, or 17.1% of sales, in the same period last year. Operating margins were negatively affected by increased E&D spending, lower operating margin from the Armstrong business and a general increase in operating costs. Organic Aerospace E&D costs increased $0.4 million compared with last year’s second quarter. Aerospace SG&A expense increased $1.7 million in the second quarter of 2015 as compared with 2014. Incremental SG&A from Armstrong was $1.6 million, including $0.7 million of purchased intangible asset amortization expense for acquired intangible assets.

Aerospace First Half 2015 Results

Aerospace segment sales increased by $30.6 million, or 12.6%, when compared with the prior year’s first six months to $274.5 million. Organic sales grew 6.9%, or $16.8 million, and sales from Armstrong added $13.8 million.

Sales to the Commercial Transport market increased $32.0 million, of which $13.8 million was related to the acquisition of Armstrong, primarily comprised of Systems Certification sales. The remaining increase was primarily higher sales of Electrical Power & Motion, Lighting & Safety and Avionics products. Sales of Electrical Power & Motion products to the Commercial Transport market increased approximately $12.6 million, or 10.5%. Sales of Lighting & Safety products to the Commercial Transport market increased by $5.0 million. Sales of Avionics products to the Commercial Transport market increased by $3.3 million. Sales to the Military market decreased $1.5 million when compared with last year’s first six months, due to lower sales of Electrical Power & Motion and Other products, partially offset by higher sales of Lighting & Safety products to this market. Sales to the Business Jet market decreased $1.0 million during this period due to lower sales of Lighting & Safety products to this market.

Aerospace operating profit for the first six months of 2015 was $43.7 million, or 15.9% of sales, compared with $38.3 million, or 15.7% of sales, in the same period last year. Operating leverage gained on increased volume for the organic business was partially offset by higher organic E&D costs of approximately $2.3 million. Aerospace SG&A expense increased $4.3 million in the first six months of 2015 as compared with 2014. Incremental SG&A from Armstrong was $2.7 million, including $1.1 million of purchased intangible asset amortization expense for acquired intangible assets. The first six months of 2014 included inventory step-up costs of $2.4 million that reduced normal operating margins for that period.

Mr. Gundermann commented, “Our Aerospace Segment continues to perform well with sales up almost 13% year-to-date and continued strong margins. We have had our strongest volume in our history in the last two quarters, bookings have more than kept pace and backlog is at record levels, suggesting continued strength going forward.”

Aerospace backlog at the end of the 2015 second quarter was $236.3 million and the book-to-bill ratio for the period was 1.02.

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

Test Systems Second Quarter 2015 Results

Sales in the second quarter of 2015 decreased approximately $12.0 million to $41.0 million compared with the same period in 2014, a decrease of 22.7%.

However, operating profit was $9.9 million, or 24.1% of sales, compared with $4.0 million or 7.6% of sales in last year’s second quarter. The 2014 second quarter reflects non-recurring purchase accounting related inventory step-up costs of $8.7 million that reduced normal operating margins for that period. This effect was partially mitigated by a decrease in E&D costs of approximately $1.3 million, to $2.8 million in the second quarter of 2015 from $4.1 million in the prior-year period.

Test Systems First Half 2015 Results

Sales in the first six months of 2015 decreased 15.8% to $60.3 million compared with sales of $71.6 million for the same period in 2014, due to lower shipments to the Commercial Electronics market. Sales to the Commercial Electronics market decreased $21.2 million compared with the same period in 2014, which was partially offset by increased sales of $9.9 million to the Military market.

Operating profit was $7.6 million, or 12.7% of sales, compared with $2.3 million, or 3.2% of sales, in the first six months of 2014. The first six months of 2014 reflected inventory step-up costs of $15.0 million that reduced normal operating margins in that period.

Mr. Gundermann commented, “Our volume in the Test business is dictated by customer schedules, but demand was strong in the second quarter and operating results were positive. The business is doing a good job of managing its cost structure while maintaining a high level of responsiveness to its customers.”

Backlog at the end of the second quarter for Test Systems was $115.7 million.

Forecast

Consolidated sales in 2015 are forecasted to be in the range of $680 million to $715 million. Approximately $545 million to $570 million is forecasted from the Aerospace Segment, adjusted from first quarter 2015 expectations of $550 million to $580 million. Test Systems segment revenue for 2015 is now expected to be approximately $135 million to $145 million, a tighter range of expectations compared with the $130 million to $160 million previously expected.

The midpoints of these ranges imply that the Aerospace Segment is expected to grow approximately 13% in 2015 and the Test Segment is expected to decline approximately 16%.

Consolidated backlog at July 4, 2015 was $352.0 million, of which $263.0 million is expected to ship in 2015.

Capital expenditures were $12.3 million in the first half of 2015 and are expected to be in the range of $20 million to $27 million for the year. E&D costs are estimated to be in the range of $75 million to $80 million.

Mr. Gundermann concluded, “We are in position for a strong close to the year. We expect the third quarter, in particular, will be a record setter with consolidated revenue of about $200 million. Our fourth quarter will be somewhat slower, depending on the rate of short-term bookings, which we are currently pursuing. All in all, Astronics’ business is developing quite well with many favorable growth prospects based on strong market positions across our broader base of solutions.”
