Shares fell by more than 10% on Monday after its results came in below the expectations of analysts.
Micro Focus, which bought the software assets of HPE and concluded the merger in September last year, reported US$1.234 billion in revenue, which was an increase of 80% year-on-year.
Of this, US$569.8 million came from the HPE Software division.
Micro Focus alone saw a fall of 7% to US$500.3 million, from US$537.7 million in the corresponding period a year ago.
The SUSE Linux division grew 13.3% to US$164 million. Back in 2012, the company's first year as a private standalone business under its former owner Attachmate, SUSE made about US$225 million in revenue.
Micro Focus executive chairman Kevin Loosemore said: “The period under review has seen the completion of the combination of Micro Focus with HPE Software to create one of the world’s largest pure play software companies.
"This was a complex transaction with 12 months between announcement and completion. We are now fully engaged in the integration of the combined company."
