Square 1 Financial, which provides banking services to venture-backed companies, raised $104 million by offering 5.8 million shares (46% from insiders) at $18, above its $15 to $17 range. The number of shares offered was reduced slightly from the original 5.9 million shares planned, with the difference coming from fewer insider shares sold. Square 1 Financial will list on the NASDAQ under the symbol SQBK. Sandler O'Neill and Keefe Bruyette Woods were the underwriters on the deal.
