Revenue rose 5 percent to $9.58 billion, against an estimate of $9.6 billion.

For the full year ended March, Lenovo posted a profit of $535 million, reversing a loss of $128 million a year prior. The result compared with the $569 million average of 24 estimates.

Annual revenue fell 4 pct to $43 billion, in line with estimates.
