Underwriting is an investment bank's guarantee to buy a new securities issue from the issuer at an agreed price and resell it to investors, earning the underwriting spread for bearing that risk.

An underwriter buys 2,000,000 new shares from the issuing company at €18.50 each and resells them to the public at €19.75 each. The underwriting spread is €19.75 − €18.50 = €1.25 per share, so the bank earns 2,000,000 × €1.25 = €2,500,000 in total, while the company receives 2,000,000 × €18.50 = €37,000,000 in net proceeds.
