Astronics shares hit an all-time high of $66.61 in early April of last year, but have steadily declined since summer as investor concerns mounted about the company's ability to replace revenues from a key contract from Apple Inc. at its test systems business. The decline accelerated earlier this month when Astronics' fourth-quarter profits fell short of analyst forecasts and the company warned that its sales this year would be roughly flat, rather than the 10 percent increase that analysts expected.
