Carlyle’s co-founders

FORTUNE — The Carlyle Group has gotten all sorts of unwanted attention this week, as majority shareholder of defense contractor Booz Allen Hamilton BAH , where NSA leaker Edward Snowden worked before hopping a flight to Hong Kong.

For the uninitiated, Carlyle CG bought a majority stake in the company’s government services business for around $2.5 billion in 2008 – via a complex transaction in which Booz Allen’s commercial business was spun off into an independent entity now known as Booz & Co. Carlyle then took Booz Allen Hamilton public in 2010 at $17 per share.

Since then the stock has experienced a number of peaks and valleys, although it’s never actually topped $20 per share. It was at $18.65 a couple of weeks ago, but is trading at just $16.65 per share as of this writing (including more than a 4% drop since Snowden identified himself).

At issue isn’t so much Booz Allen’s specific connection to Snowden, but rather that this episode could cause the government to reduce its epic reliance on outside contractors for intelligence work.

This is where things could get a bit dicey for Carlyle. The firm already has made back well more than its original $956 million equity investment via dividend recaps (it also provided some mezzanine capital), but it never sold any of its 98 million or so shares. Not in the IPO, nor in the intervening 31 months.

The firm’s 70% position currently is valued at around $1.64 billion, or $120 million lower than it was at market close last Friday. And if the company actually does face a major loss of business, then the value would only go down from here.

Obviously that’s all hypothetical and predicated on long-term behavioral changes caused by an event that’s still less than a week old. But, if it comes true, then Carlyle may have wished it had already begun selling down a bit…
