Investors are optimistic with L-3 Communications Holdings Inc. [LLL], sighting the company’s second quarter results show growth as well as continued integration success.

The company reported revenue of $461 million, an improvement of 22.2 percent compared with its first quarter results and 46.6 percent compared with its second quarter results last year.

Likewise, C.E. Unterberg, Towbin Analyst William Kidd said L-3’s business acquisitions late last year played a significant role in its current results. “Though not evident in the numbers, what is so impressive about its margin improvements is the fact that it resulted from businesses acquired in the fourth quarter last year that needed a little of L-3’s restructuring,” Kidd said. “The fact that fourth quarter acquisitions appear to be productive in only six months is a credit to strong L-3 management.”

In addition, L-3 won $480.5 million in firm orders in the second quarter–its strongest quarter in orders in the last two years. “Continuing at this rate of growth, firm orders should have little trouble meeting management’s guidance of $2 billion in firm orders for the year,” Kidd added.

The merchant supplier company, primarily to the defense industry, is known for its secure communications systems and specialized communications products.
