NEW YORK: Data centre operator DayOne Data Centers filed for an initial public offering in the United States on Monday, testing investor appetite for data-center listings amid challenging market conditions.

The company posted a net loss of US$77.2 million on revenue of US$512 million for the six months ended June 30, compared with a loss of US$12.6 million on revenue of US$151.5 million a year earlier.

The filing comes as surging bond yields and elevated interest rates cloud the outlook for the fall IPO market, prompting several major listings to be postponed.

Data centres have also come under scrutiny over their heavy use of electricity, water and land, with communities raising concerns about their impact on power grids, utility bills and local resources.
