Last week’s initial public offering (IPO) action saw four of five scheduled listings make their entry into the public markets. The four IPOs raised a total of $307 million in new capital, as three of the four priced below the midpoint of their expected ranges. The coming week includes two small offerings seeking a total of $58 million, one a first-timer and one a holdover from last week.

Amalgamated Bank (NASDAQ: AMAL) raised $104 million selling 6.7 million shares at $15.50, near the low-end of the expected range of $15 to $17. Shares dropped 3% on their first trading day but ended the week up 6%.
