In reply to woolsack:
A few things:
Oh course it's galling when a few people make a mint, but it's not the first time and it won't be the last.
QinetiQ was not a sure-fire thing - AEA Technology was the closest previous comparison and went the other way.
Carlyle wasn't the only bidder, but (I think) was the only one that was able to stump up an acceptable sum and would not jeopardise the company's raison d'etre - providing independent advice to the MOD and would be acceptable to the rest of the defence industry - that ruled out BAE or Thales as purchasers for a start.
By the time Carlyle sold up, a huge amount had changed, but without the change of environment that wouldn't have happened.
At the time of the sale, QinetiQ's formerly guaranteed research revenue from the MOD was being turned off. So how much would you have paid for a company that had hitherto relied almost entirely on handouts when those handouts were being turned off?
The MOD also shifted a £245 million pension liability off its books.
So the foot-scanner is one spin off - if you're reading this on an LCD screen, that's another (the patent for which expired this year, so that's a chunk of revenue gone). If you use a mobile phone, you will use a dual network QinetiQ designed antenna at some point. If you own anything with carbon fibre in it, that's another; flat panel speakers, the little sticky-out doofrey-wotsits on airliner wings, GPS receiver chips, a radar that scans runways for debris (cp Paris Concorde accident) now sold to Vancouver and Qatar, I think.
Easy to be wise after the event, but another company with suitable ownership and business could have offered a bit more with a decent plan for the business and a small matter of the staff and attendant liabilities and beaten Carlyle to it.
So why didn't they? Too big, too scary and too difficult mainly.
