BEIJING — Huawei Technologies, one of the largest makers of telecommunications equipment in the world, bounced back from a disappointing 2011 with a 33 percent rise in net profit for 2012 and forecast stronger revenue growth, buoyed by smartphone sales and cloud computing.

Huawei’s chief financial officer, Cathy Meng, the daughter of the company’s founder, Ren Zhengfei, denied that U.S. security concerns would hamper the privately held company’s growth and said Monday that it would keep “an open mind” about a possible stock market listing.

“Cloud computing is a huge sector in the next five years,” Ms. Meng told a results presentation. “In the telecom industry, we are expecting a 5 percent increase in capital investments. Smartphone penetration is still way too low and there is a lot of room for growth. So these three areas will create a lot of opportunities for us.”

Huawei, which ranks behind only Ericsson of Sweden in telecommunications equipment, reported an unaudited net profit of 15.4 billion renminbi, or $2.5 billion, up from 11.6 billion renminbi in 2011, as new telecommunications projects and smartphones increased sales.
