L-3 Communications Holdings Inc. (LLL) reported a better-than-expected 19% rise in third-quarter earnings. That led the defense contractor to again raise its full-year earnings guidance.

The company, which has contracts for such services as training foreign militaries and upgrading government aircraft, now expects 2009 earnings of $7.45 to $7.50, up as much as 20 cents from its July view. It lowered the top end of its expected revenue range by $100 million.

L-3 also predicted 2010 earnings of $7.85 to $8.05 on revenue between $15.7 billion and $15.9 billion. The mean estimates of analysts surveyed by Thomson Reuters were $7.92 and $16.1 billion, respectively.

Chairman and Chief Executive Michael Strianese said the most recent period was a good one, led by strength in the company's segment providing command, control, communications, intelligence, surveillance and reconnaissance services. "Looking ahead, we are well positioned for shifting customer priorities and slowing U.S. Department of Defense budgets," he added.

L-3, which differs from larger rivals who rely on a few major contracts for the bulk of revenue, has said the diversity of its operations will see them through the changes in U.S. defense spending. The Pentagon is cutting back on expensive weapons programs meant for traditional battle and increasing money for lower-tech programs to counter insurgencies in Iraq and Afghanistan. The company also has reduced its debt and pushed back maturities, a key factor in both Moody's Investors Service and Fitch Ratings upgrading the company, the latter moving it to investment-grade status.

L-3 posted a profit of $250 million, or $2.12 a share, up from $210 million, or $1.70 per share a year earlier. The latest results included a tax benefit of 22 cents. Revenue increased 4.9% to $3.84 billion.

In July, the company predicted earnings of $1.85, slightly above analysts' expectations at the time, on revenue between $3.8 billion and $3.9 billion.

Funded orders fell 15% from the year-earlier period to $3.4 billion. Funded backlog decreased 6% to $10.8 billion.

L-3 shares closed Monday at $74.16 and weren't active premarket. The stock, which hit a four-year low in March, is roughly flat for the year.
