SAN FRANCISCO -- Celestica's chief financial officer says the end-of-year outlook is shaping up per previous guidance, and the company reiterated its revenue growth of 6 to 8% for the year.

Speaking at the Deutsche Bank tech conference in San Francisco, Paul Nicoletti said the electronics manufacturing services company is aggressively targeting higher margin businesses in order to improve margins.

He said the firm wants to increase its position in the military, aerospace, medical and industrial markets to 25% of total revenue within three to five years. Currently, the contract assembler says these markets comprise about 11% of revenue.

Last year, Celestica had revenues of $6.09 billion.

Celestica, ranked fourth in the world in EMS, sees the low-volume, high-mix business as boosting operating margins, which currently run the neighborhood of 3.5%. Management says operating margins could hit 4% as its low-volume, high-mix business tops 20% of revenue.

Nicoletti added that new programs with top customers RIM and Sun are ramping to forecast.
