The technology giant’s revenue at all its main business units was down except cloud, which has been the centrepiece of its turnaround strategy.
IBM’s cloud and cognitive segment, which includes analytics, cybersecurity and artificial intelligence, fell 1.5 percent to $5.04 billion in the quarter but beat FactSet estimates of $4.18 billion.
Chief Financial Officer Jim Kavanaugh said: “We saw good acceleration in our cloud business... We now have an improving trajectory.”
Under Ginni Rometty’s stewardship, the company has shed many of its traditional hardware businesses and beefed up the growth areas through deals such as its $34 billion acquisition of Red Hat.
IBM returned to annual revenue growth in the last quarter of 2018, triggering expectations that its strategy was taking roots.

Its overall revenue slipped 4.7 percent to $18.18 billion in the first quarter ended March 31 and missed the average analyst estimate of $18.46 billion.
