An open offer gives existing shareholders a proportional opportunity to buy new shares without a separately tradable entitlement.
An open offer is an invitation to existing shareholders to buy new shares in proportion to their holdings without using a renounceable, separately tradable entitlement. The company raises equity capital, but a shareholder who does not participate generally cannot sell the entitlement as in a traditional rights issue.
This is primarily UK capital-markets terminology. Other jurisdictions use “open offer” for different transactions, including takeover or tender structures. Confirm the context before applying the definition.
Assume a company with 100 million shares outstanding makes a 1-for-4 open offer at $8 when its shares trade at $12 before becoming ex-entitlement.
A holder of 400 shares may subscribe for 100 new shares by paying $800. If the holder participates fully, ownership remains proportional at 500 shares out of 125 million.
If the holder does not participate, the holding remains 400 shares while the denominator rises to 125 million. The holder’s percentage ownership falls by 20% relative to the previous percentage. Unlike a renounceable rights issue, the holder generally cannot sell the open-offer entitlement to recover its theoretical value.
| Feature | Open offer | Rights issue |
|---|---|---|
| Offered to existing holders proportionally | Yes | Yes |
| New shares raise issuer capital | Usually | Usually |
| Entitlement separately tradable | Generally no | Commonly yes in UK usage |
| Holder can sell rather than subscribe | Generally no | Usually, during the rights trading period |
| Non-participant compensation | Only if the structure provides it | May arise through sale or rump treatment under the documents |
Current FCA open-offer rules distinguish ordinary open offers from open offers with a compensatory element and caution against implying that an open offer provides the same entitlement as a rights issue unless that element exists.
The share price may fall below the subscription price before completion. A non-participant may lose percentage ownership without the ability to sell an entitlement. A controlling holder may also increase influence if other holders do not participate.
Do not use “open offer” and “rights issue” interchangeably, assume the discount is free value, or assume untaken entitlements are compensated. This page is educational and not investment, legal, or tax advice.
