Exhibit 99.1

ESTERLINE REPORTS FISCAL 2018 SECOND QUARTER FINANCIAL RESULTS

BELLEVUE, Wash., May 3, 2018 – Esterline Corporation (NYSE:ESL) (www.esterline.com), a leading specialty manufacturer serving global aerospace and defense markets, today reported results for the fiscal 2018 second quarter ended March 30, 2018.

Consolidated second quarter revenue was $517.6 million, an increase of 1.7% from the prior-year result of $509.1 million.

Consolidated earnings from continuing operations in the second fiscal quarter of 2018 were $24.0 million, or $0.80 per diluted share, compared with $34.4 million, or $1.15 per diluted share, in the 2017 period. Adjusted earnings from continuing operations for the second fiscal quarter of 2017 were $35.3 million, or $1.18 per diluted share, excluding discrete advanced displays integration and compliance costs.

“Esterline’s baseline operational performance is on track with our expectations through the first half of fiscal 2018,” said Curtis Reusser, Esterline’s Chairman, President & CEO. “We are gaining traction with our customers and healthy booking activity has driven our backlog to new highs. In addition, a large customer has asked us to work closely with them on a new development effort. We had not contemplated the required investment for this new development activity in our original plans for the year and we are adjusting our outlook accordingly. These trends are encouraging and are laying a foundation for progress that should support long-term growth.”

He added, “The company is continuing to produce excellent cash flow, allowing us to remain flexible in executing our disciplined capital allocation strategy. From a strategic perspective, the sale of the Kirkhill business, completed during the second quarter, positions our Advanced Materials businesses to deliver expanded operating margins and improved results going forward and led to an increased guidance range for free cash flow.”

Second Quarter Results of Operations

The Avionics & Controls segment reported fiscal second quarter operating earnings of $23.7 million on sales of $212.8 million. This compares with operating earnings of $20.8 million on sales of $213.3 million in the same period of fiscal 2017. The segment’s second quarter 2018 results benefited from the execution of a $2.3 million licensing agreement for legacy products.

The Sensors & Systems segment reported fiscal second quarter operating earnings of $19.3 million on sales of $198.2 million. The segment’s operating earnings were $26.4 million on sales of $182.7 million in the same period of fiscal 2017. Better profitability at the segment’s Advanced Sensors and Connection Technologies businesses partially offset lower profits within the segment’s Power Systems business. Operating margins for the Power Systems business in the fiscal 2018 second quarter declined, as 2017’s sales mix included strong retrofit program sales from an FAA mandated safety program. That retrofit program is now largely complete.

The Advanced Materials segment reported sales of $106.7 million in the fiscal 2018 second quarter and operating earnings of $9.6 million. Segment results were affected by a $5.2 million loss from operating activities at the Kirkhill business driven largely by repricing on a long-term defense contract and a $6.0 million loss attributable to the sale of the business and associated expenses. The segment reported operating earnings of $28.3 million during the same period of fiscal 2017 on sales of $113.1 million. Segment results in the fiscal 2017 second quarter benefited from a $5.2 million business recovery insurance payment and a $2.1 million operating profit at the Kirkhill business.

The company reported consolidated operating earnings before interest and tax in the second quarter of fiscal 2018 of $33.9 million, or 6.6% of sales, compared with $55.4 million, or 10.9% of sales, in the prior year. The year-over-year decline was driven primarily by lower operational performance at the Kirkhill business, the loss on the sale of Kirkhill, and lower operating results from the Power Systems business.

The effective income tax rate of 7.9% for the fiscal second quarter of 2018 mainly reflected the tax benefit from a reduction of a capital valuation reserve related to the sale of the Kirkhill business.

Year-to-Date Results of Operations

Consolidated operating results for the first six months of fiscal 2018 include discrete tax expenses of $48.6 million, or $1.62 per diluted share, related to the U.S. Tax Cuts and Jobs Act of 2017 (TCJA). Including that impact, the company reported a loss from continuing operations for the first six months

of fiscal 2018 of $10.9 million, or $(0.36) per diluted share. Excluding the discrete impact of the TCJA, the company generated earnings from continuing operations during the first half of this fiscal year of $37.7 million, or $1.26 per diluted share. Earnings from continuing operations for the first six months of fiscal 2017 were $55.6 million, or $1.86 per diluted share. Adjusted earnings from continuing operations for the first six months of fiscal 2017 were $59.4 million, or $1.99 per diluted share (see further details in the Non-GAAP Financial Information section below).

Cash flow from operations through the first six months of fiscal 2018 was $89.7 million, compared with $91.3 million through the first six months of fiscal 2017. Capital expenditures during the first six months of fiscal 2018 were $27.7 million, resulting in free cash flow of $62.0 million for the period.

Bookings and New Programs

New orders in the fiscal second quarter of 2018 were $651.2 million compared with $466.3 million in the comparable period of fiscal 2017. Year to date, the company’s book-to-bill ratio is 1.2x. The company’s backlog has steadily increased over the past twelve months, standing at $1.46 billion at the end of the 2018 fiscal second quarter, compared with a $1.21 billion backlog at the end of the 2017 fiscal second quarter. The current backlog has greater depth with a higher proportion of system and sub-system orders with scheduled deliveries twelve months or more into the future.                

Kirkhill Sale

On March 15, 2018, the company completed the sale of its Kirkhill business recording $6.0 million of pre-tax loss and directly related expenses consisting of a $5.3 million loss on the sale and $0.7 million of related expenses. The sale resulted in a $0.2 million after-tax gain.

Share Repurchase Activity

During the fiscal second quarter of 2018, the company repurchased approximately $23 million of its shares under the existing share repurchase authorization, acquiring 313,900 shares at an average price of $73.29 per share. As of March 30, 2018, the company had about $48 million remaining under its existing repurchase authorization.

Fiscal 2018 Outlook

The company has adjusted its guidance outlook to account for several factors, including the pursuit of a new business opportunity not previously contemplated, the Kirkhill business sale, and the cost of completing the recent financial restatement. The company has adjusted its revenue guidance to a range of $2.00 billion to $2.05 billion, from $2.025 billion to $2.075 billion. The company narrowed its fiscal 2018 earnings guidance range to $3.65 to $3.85 per diluted share, from $3.65 to $4.05, and increased its free cash flow guidance by $10 million to a range of $115 million to $140 million.

Additional information about the company’s financial results is available in a presentation on the company’s website (www.esterline.com) in the Investor Relations section under “Presentations.” The presentation is also included as Exhibit 99.2 to the company’s report on Form 8-K, which is being submitted today to the SEC.

Non-GAAP Financial Information

This press release and the related presentation providing supplemental financial information may include non-GAAP financial measures—adjusted earnings from continuing operations, adjusted earnings from continuing operations per diluted share, adjusted operating earnings from continuing operations (EBIT), adjusted earnings before interest, tax, depreciation and amortization (EBITDA), adjusted SG&A expense, and free cash flow—that have not been calculated in accordance with generally accepted accounting principles (GAAP) in the U.S. Where referenced in these materials, adjusted earnings from continuing operations consist of earnings from continuing operations attributable to Esterline less the costs associated with incremental compliance costs (described further below), discrete items associated with our acquisition of the Advanced Displays business in January 2015, and the one-time expenses associated with the TCJA. Adjusted earnings from continuing operations per diluted share divides each element of adjusted earnings from continuing operations by the weighted average number of shares outstanding, diluted for the periods presented. EBIT is defined as operating earnings from continuing operations. Adjusted EBIT excludes the same costs excluded from adjusted earnings from continuing operations set forth in the table below. EBITDA from continuing operations is defined as net earnings (loss) plus loss from discontinued operations plus earnings attributable to noncontrolling interests plus income tax expense less interest income plus interest expense plus depreciation & amortization (excluding amortization of debt issuance costs) of $27.7 million in the second quarter of fiscal 2018. Free cash flow is defined as cash flow from operations of $89.7 million less capital expenditures of $27.7 million in the first six months of fiscal 2018. In accordance with the SEC’s requirements, below is the reconciliation of the non-GAAP adjusted earnings from continuing operations to the comparable GAAP earnings from continuing operations in the applicable periods. Additional relevant reconciliations are included in the presentation providing supplemental financial information.

The company provides these non-GAAP financial measures as supplemental information to the GAAP financial measures. Management uses these non-GAAP financial measures to (a) evaluate the company’s historical and prospective financial performance and its performance relative to its competitors, (b) allocate resources, and (c) measure the operational performance of the company’s business units.

In addition, management believes including these non-GAAP financial measures enhances investors’ and financial analysts’ understanding of the company’s performance as well as their ability to assess and compare the company’s historical results of operations.

These non-GAAP financial measures are not meant to be considered in isolation or as a substitute for the comparable GAAP measures, and free cash flow is not necessarily indicative of amounts available for discretionary use. There are limitations to these non-GAAP financial measures because they are not prepared in accordance with GAAP and may not be comparable to similarly titled measures of other companies due to potential differences in methods of calculation and items that comprise the calculation. The company compensates for these limitations by using these non-GAAP financial measures as a supplement to the GAAP measures and by providing reconciliations of the

non-GAAP and comparable GAAP financial measures. The non-GAAP financial measures should be read only in conjunction with the company’s consolidated financial statements prepared in accordance with GAAP.
