In a year of little tech IPO activity, project management software company Atlassian has upsized its proposed IPO, now planning to sell 22 million shares at a price between $19 and $20. The company had earlier filed to raise roughly $350 million by pricing its offering in the range of $16.50 to $18.50 per share when it moves to list on the NASDAQ under the symbol TEAM. Atlassian has more than 51,000 customers and generated FY2015 revenues of $320 million and net income of $7 million for the same period. If shares price at the new range midpoint, the company will be valued at nearly $4.1 billion, about $800 million higher than the valuation it received with its most recent financing in April 2014. Backers include Accel Partners, which holds a 12.5% pre-IPO stake.
