Shares in UK cybersecurity company Darktrace soared on debut, gaining 40% to 350p each after their sale in an initial public offering valuing the firm at ยฃ1.7bn.
The company raised ยฃ165.1m, with ยฃ143.4 coming from a global offer and shareholders selling ยฃ21.7m in stock at 250p each. Conditional dealing in the shares started on Friday with retail trade scheduled for May 6.
In addition, a further 9.9m shares are being made available in an over-allotment option, which could see 11% of the company’s stock sold with the cash used for general corporate purposes.
The company is looking to raise cash for its Cambridge research and development operation. It uses artificial intelligence to understand computer networks and detect attacks by identifying unusual behaviour.
Reports earlier this month suggested the valuation could be as high as ยฃ4bn. However, the recent debut failure of online takeaway delivery platform Deliveroo and concerns in the market about Darktrace’s links to Mike Lynch, the Autonomy founder facing US fraud charges, saw the pricing range scaled back.
Lynch denies the claims against him and Darktrace chief executive Poppy Gustafsson on Friday thanked his Invoke Capital team.
“We owe much gratitude to the Invoke team for their pivotal role in the vision, technology, positioning and operational input in the early years without which today’s success would not have been possible,” she said in a statement.
Other investors include venture capitalists Balderton Capital, Talis Capital, Hoxton Ventures, Summit Partners, KKR, TenEleven Ventures, Insight Partners and Vitruvian.
Invoke is not allowed to sell stock for 180 days, while employees are subject to a 360 day lock-up.
