Shares at the business, which helps cybersecurity companies connect to other firms, are set to start trading in Paris on Thursday. They were previously expected to be priced between a range of €20 and €24.
The IPO includes a 15% over-allotment option, which when exercised could take the deal size to as much as €480m.
Exclusive Networks aims to use the proceeds from the float to expand into various markets overseas, and grow the business through mergers and acquisitions.
Existing shareholders include private equity firm Permira Holdings, which is controlled by former chief executive officer Olivier Breittmaye.
In its most recent financial results, the company reported a profit of €108m last year on the back of €2.9bn in sales.

Its debut will extend a strong run of listings in France, after a dismal two years, with investment firm Antin Infrastructure Partners also looking to float its shares at €24 in Paris, valuing the firm at €4.1bn. Health-care property firm Icade Sante also announced planned IPOs this month.
The number of European listings hit their highest level in 14 years in the first half of the year.
Cybersecurity has also boomed over the last year. This is due to more people working away from the office to combat the spread of coronavirus, boosting the need for protection amid rising levels of cybercrime.
Darktrace (DARK.L) made its debut on the London Stock Exchange in April, and has surged almost 180% since. Its listing was one of the most prominent to emerge from the UK’s cluster of tech unicorns — companies with a valuation of at least $1bn.

Darktrace, which was founded in Cambridge in 2013, uses artificial intelligence (AI) technology to spot cyber threats for businesses.
The AI is used to build what it calls an “enterprise immune system” that monitors companies' computer networks to detect unusual activity and then respond to it. The technology stands in contrast to traditional cyber security software that tries to build a wall around networks to block intruders.
