Shares of Irvine-based Alteryx Inc. surged in its first trading session on the New York Stock Exchange.

The company Thursday evening priced its initial public offering at $14 per share, the high end of an initial estimate provided earlier this month, and investors sent shares up nearly 9% to $15.45 in midday trading.

Shares trade under the symbol “AYX.”

The analytics software maker plans to sell 9 million shares of Class A common stock and grant underwriters a 30-day option to purchase up to an additional 1.35 million shares of Class A common stock.

Net proceeds from the offering are expected to be $126 million, or $145 million, if underwriters exercise their option to purchase the additional shares in full.

Goldman, Sachs & Co. and J.P. Morgan Securities LLC are joint book-running managers for the offering. Pacific Crest Securities, a division of KeyBanc Capital Markets Inc., William Blair & Company LLC., JMP Securities LLC, Raymond James & Associates Inc., and Cowen and Company LLC are co-managers.

Alteryx backers include Newport Beach-based Toba Capital, Insight Venture Partners, Sapphire Ventures, Thomson Reuters and ICONIQ Capital, among others.

Alteryx was the No. 19 largest software maker in Orange County last year with 120 local workers, according to Business Journal research.

The company commemorated the event by ringing the bell this morning at the NYSE.
