Companies that have given up IPO plans file a registration withdrawal request, form RW, notifying the SEC and the public that they will no longer proceed with an offering. An IPO can withdraw for various reasons. They may have been acquired, found private funding, had a bad quarter, or face a bout of market volatility. However, the most common reason is that there was insufficient demand for the deal. Despite this, many companies cite "market conditions" as the reason for their withdrawal. The fault, they say, was in our stars.
