Toronto-based software firm Q4 has decided to once again pursue a $150-million Toronto Stock Exchange initial public offering that it put on hold this summer. Meanwhile, shares of Vancouver’s Copperleaf, which upsized its offering Wednesday, hit a high of $24.49, up more than 63 per cent from its $15-per-share offering price on its first day of trading. (The Logic)

Talking point: Q4 first filed to go public in May with an eye to raising $150 million, but later paused the plans, reportedly due to a contract-renegotiation issue. It aims to price shares at between $14 and $17.50, raising up to $172 million if the over-allotment option is exercised in full. The offering would give it a market capitalization of nearly $657 million at the midpoint share price, assuming a full over-allotment option. Copperleaf’s market debut comes after it broke a relatively quiet period for Canadian tech firms on the public markets. Earlier this week, Montreal-based Sharethrough, an advertising-exchange tech firm, followed its lead, filing to trade under the symbol STRX.
