Backstop in Securities Offering
A backstop in a securities offering is a commitment to buy unsold securities if other investors do not fully subscribe.
Firm commitment, best efforts, standby underwriting, back-stop, and sweetener terms.
Underwriting Commitments and Backstops covers public offerings, IPOs, underwriting, private placements, rights issues, subscriptions, allocation, project finance, and other channels for raising capital.
Use these pages when an issuer raises debt, equity, or hybrid capital and the term affects disclosure, pricing, allocation, investor access, intermediary risk, or dilution. It sits inside Underwriting Commitments and Offering Methods, so readers can move up when the broader company-finance context matters.
Use the table below to choose the narrower corporate-finance branch before applying a term to a model, board memo, financing analysis, transaction review, or risk assessment. Move into the term page when the evidence source, calculation, agreement, filing, account, or governance right matters.

Issuance content is educational and does not provide securities-offering, legal, tax, underwriting, or investment advice.
Choose a subsection first. Deeper term pages live inside each subsection, which keeps large topic hubs readable.
