Investopedia explains Bridge Financing
These funds are usually supplied by the investment bank underwriting the new issue. As payment, the company acquiring the bridge financing will give a number of shares at a discount of the issue price to the underwriters that equally offsets the loan. This financing is, in essence, a forwarded payment for the future sales of the new issue.
