The CEO of NASDAQ says the stock exchange is "humbly embarrassed" by its bungling of Facebook's hugely anticipated debut as a public company on Friday.

Robert Greifeld tells news media there's no indication the delay contributed to the underwhelming performance of Facebook's stock, which ended at $38.23 — 23 cents above where it began.

Facebook's stock was expected to start trading at 11 a.m. but didn't open until 11:32 a.m., and some investors didn't learn for hours whether their orders went through.

Greifeld called the social network's first day of trading "successful." He said late order cancellations caused a glitch, according to reports published Sunday. He said Nasdaq's board met Saturday and plans to change its IPO auction process.

The Securities and Exchange Commission has said it is investigating.
