The summer initial public offering (IPO) market has come to a close following the long Labor Day weekend. Last week, four small companies raised about $50 million in total, while the shortened week ahead plans to only add two listings.

In IPO news, Chobani announced it was withdrawing its plans for an initial public offering, according to a regulatory filing on Friday. The food and beverage company filed in November to go public on the Nasdaq Exchange using the ticker "CHO", and was expected to be a large IPO later this year.

In an email statement to CNBC, Chobani cited current market conditions for the withdrawal. "Our focus remains on strong execution and driving profitable growth, and we continue to be excited about the future of Chobani," the company said in the statement.
