Astronics Corporation Initiates $30.0 Million At-The-Market Program

Astronics Corporation (Nasdaq: ATRO), a leading provider of advanced technologies for global aerospace, defense, and other mission critical industries, today announced it has initiated an at-the-market (“ATM”) equity offering program for the sale from time to time of shares of the Company’s common stock (the “Common Stock”) having an aggregate sales price of up to $30.0 million. The timing and volume of any sales of shares of Common Stock under the ATM program will depend on a variety of factors to be determined by the Company. Shares of Common Stock under the ATM program will be offered through Wells Fargo Securities, LLC (“Wells Fargo”) and HSBC Securities (USA) Inc. (“HSBC”), as sales agents. Wells Fargo and HSBC may sell shares of Common Stock by any lawful method deemed to be an “at-the-market offering” defined by Rule 415(a)(4) of the Securities Act of 1933, as amended, including without limitation sales made directly on the Nasdaq Global Select Market, on any other existing trading market for the shares of Common Stock, to or through a market maker or in negotiated transactions. Sales may be made at market prices prevailing at the time of the sale, at prices related to prevailing market prices or at negotiated prices and, as a result, sales prices may vary.
