What is a pipe deal?

When companies want to raise funds by selling equity and when those equities are purchased by private investment firms, mutual funds or other qualified investors at a discount to the current market value, is a PIPE deal.

There are two main types of PIPEs - traditional and structured. A traditional PIPE is one in which stocks, either common or preferred, are issued at a set price. A structured PIPE, on the other hand, issues convertible debt (common or preferred shares).
