Elastic N.V. priced its initial public offering of 7 million shares at $36 a share, to raise $252 million, and to value The Netherlands-based big data search company at about $2.50 billion. The pricing late Thursday was above the expected range of $33 to $35 a share. If the underwriters, led by Goldman Sachs and J.P. Morgan Securities, exercise all the options to buy additional shares, the company could raise up to $289.8 million. The stock is expected to begin trading Friday morning on the NYSE under the ticker symbol "ESTC."
