COBHAM ADDS AEROFLEX FOR $920 MILLION TO LIFT CIVIL SALES

According to Bloomberg News, Cobham Plc (COB) agreed to buy Aeroflex Holding Corp. (ARX) for $920 million in cash as the world’s No. 1 manufacturer of warplane-refueling gear makes its biggest-ever acquisition to expand in commercial markets.

Cobham is offering $10.50 a share, and will also take on $540 million of debt, the Wimborne, England-based company said today in a statement. Aeroflex, a manufacturer of radio and microwave products and test equipment with its headquarters in Plainview, New York, closed at $8.31 yesterday.

Buying the U.S. supplier to space, avionics, medical and energy clients spanning Boeing Co. (BA) to Nokia Oyj (NOK1V) will reduce Cobham’s reliance on a shrinking defense market, which will account for 59 percent of group revenue, down from 65 percent. The deal follows the purchases of Axell Wireless Ltd. last May and satellite-equipment supplier Thrane & Thrane A/S in 2012.

“Given the mix of Aeroflex, the acquisition really helps us change the shape of our portfolio so we continue to get more exposure to growing commercial end markets,” Chief Executive Officer Bob Murphy said on a conference call today. “That’s what’s going to help us really deliver sustainable growth.”

Uncertain Times for DefenseIn Defense of DARPA; Lamenting Bell Labs
By Barry Manz

A federal agency like DARPA is a sitting duck for politicians and assorted other critics. It has come up with some truly bizarre programs over years that ultimately either delivered no tangible results, were canceled before they could cause any damage, or attempted to answer questions that nobody was asking or needed answers to.
