Australian software champion Atlassian led three of the world’s largest technology companies in a share price downturn as each reported disappointing results on Friday morning.

Atlassian, which makes workplace collaboration software, was punished with a 13 per cent fall in its share price in after hours trading while Apple, Google owner Alphabet and Amazon all saw modest slides between 3 and 4.2 per cent at 11am AEDT.

The sharp slide cut billions from Atlassian’s value, hitting the wealth of its high-profile founding duo, Mike Cannon-Brookes and Scott Farquhar, who remain major shareholders.

Bloomberg’s billionaires index put Cannon-Brookes and Farquhar’s net wealth at about $US11 billion each on Thursday (US time), with the news outlet reporting each man holds 22 per cent of Atlassian’s stock as the dominant source of their fortune.

The company was worth $US46.6 billion ($66 billion) on Friday AEDT, before the share price fall, which suggests the value of each of the founders’ holdings will fall by about $US1.2 billion if the after-hours drop materialises when the NASDAQ reopens.

Atlassian reported 27 per cent revenue growth for the quarter to $US873 million, but its net losses widened substantially to $US205 million and its gross margins slipped about 1 per cent. Its forecast earnings were below some analysts’ hopes, but in line with average expectations.

Cannon-Brookes and Farquhar wrote in a letter to shareholders that a harsh macroeconomic environment was continuing, with Atlassian signing up new paying customers and expanding existing subscriptions at a slower rate. The company would shift more resources to its highest growth areas, such as its cloud products and large enterprise customers.

“We’ve played offence amid uncertainty more than once in our 20 years as a company, and we’re confident that our trademark vigilance and discipline will guide us through successfully once again,” Cannon-Brookes and Farquhar wrote.
