What it means
The structure is described as a ratio, such as one-for-four, meaning a shareholder may buy one new share for every four already held. The discount matters less than it looks, because issuing shares below market price mechanically pulls the market price down towards a blended figure once the new shares exist.
Companies choose this route when they need equity rather than debt: to fund an acquisition, repair a stretched balance sheet, or meet a regulatory capital requirement. It is generally cheaper than a public offering to new investors and it respects existing shareholders' preemptive rights, the entitlement to maintain their percentage ownership.
The blended price after the issue is called the theoretical ex-rights price, and it is the anchor for everything else. The right itself has a value equal to the gap between that blended price and the subscription price, spread across the number of existing shares needed to buy one new one.
A shareholder who takes up the rights in full is, in theory, no better and no worse off, because the money they put in matches the value of the extra shares they receive. A shareholder who ignores the offer entirely is worse off, because their existing shares fall to the blended price and they receive nothing in return, which is why unexercised rights are usually sold rather than left to lapse.
Most offerings are underwritten, meaning an investment bank agrees to buy any shares shareholders do not take up, guaranteeing the company its money for a fee. The market often reads a deeply discounted rights issue as a sign of distress, so the announcement itself can move the share price before any of the arithmetic applies.
In practice
Real-world examples.
Example
A regional bank falling short of its regulatory capital requirement launches a one-for-three rights offering at a 25% discount. Existing shareholders provide the capital, and the bank avoids the far more expensive route of selling a stake to an outside investor at a distressed valuation.
Example
A property group funding a $300,000,000 portfolio acquisition uses a rights offering rather than more debt, because its lenders have signalled that another borrowing round would breach its leverage covenant.
Example
A retail investor holding 800 shares in an airline receives rights during a cash crunch and cannot afford to subscribe. Their broker sells the rights in the market for roughly their theoretical value, offsetting most of the fall in the share price.
Think of it
“Rights offering allows shareholders to buy proportionally-maintaining their stake.
Formula
Calculation
Theoretical ex-rights price (TERP) = (Existing shares x Market price + New shares x Subscription price) / Total shares after the issue
Value of one right per existing share = (TERP - Subscription price) / Number of rights needed for one new share
A company has 10,000,000 shares trading at $20, giving a market value of $200,000,000. It announces a one-for-four rights offering at a subscription price of $15.
New shares issued = 10,000,000 / 4 = 2,500,000. Money raised = 2,500,000 x $15 = $37,500,000.
TERP = ($200,000,000 + $37,500,000) / 12,500,000 shares = $237,500,000 / 12,500,000 = $19.00.
Value of one right per existing share = ($19.00 - $15.00) / 4 = $1.00.
Check it from a shareholder's point of view. Someone holding 400 shares owns $8,000 of stock before the offer. They subscribe for 400 / 4 = 100 new shares at $15, paying $1,500. They now hold 500 shares worth 500 x $19.00 = $9,500, which is exactly $8,000 + $1,500. Taking up the rights in full leaves them neither better nor worse off; ignoring the offer would have left their 400 shares worth 400 x $19.00 = $7,600, a $400 loss equal to the rights they threw away.Case study
Seen in the real world.
Calderbrook Freight is an illustrative, fictional logistics company that needed $37,500,000 to refinance a maturing bond and chose a one-for-four rights offering at $15 against a $20 market price. The board expected a straightforward exercise, since the discount looked generous.
Two things surprised them. The share price fell to around $19 the moment the offer was announced, which several shareholders read as the market punishing the company, when in fact it was the arithmetic of the theoretical ex-rights price doing exactly what it always does. Meanwhile a group of smaller holders let their rights lapse simply because the paperwork looked complicated.
The company responded with a plain-English explainer showing the $8,000 holder becoming a $9,500 holder for $1,500 of cash, and arranged for lapsed rights to be sold on shareholders' behalf. In this illustrative example, take-up on the next capital raising was far higher, and the underwriting fee correspondingly lower.
Watch out
Common mistakes.
- Seeing the discount as free money. The subscription price is below the market price, but the market price itself falls to the blended figure once the new shares exist, so the discount is not a gift.
- Letting rights lapse without selling them. Doing nothing gives up real value, because the shares still fall to the theoretical ex-rights price whether or not the shareholder participates.
- Assuming every rights offering signals trouble. Some fund genuine growth or acquisitions, and the size of the discount and the stated use of proceeds tell you far more than the existence of the offer.
Questions
People also ask.
What happens if I do not take up my rights?
Your holding is diluted and your shares fall to the blended price, though in most offerings the unexercised rights are sold on your behalf or by your broker and the proceeds returned to you.
Is a rights offering the same as a share split?
No, a share split divides existing shares into more pieces and raises no money, while a rights offering issues genuinely new shares in exchange for new cash.
Why is the subscription price set below market?
A discount gives shareholders a real incentive to participate and gives the company a buffer if the share price drifts down before the offer closes.
