Rights Offering
A rights offering lets existing shareholders buy new shares at a discount before the general market, protecting them from dilution if they choose to participate.
Definition
A rights offering is a method of raising equity capital in which a company offers existing shareholders the right (but not the obligation) to purchase additional shares at a discounted price, in proportion to their current holdings. Rights are typically transferable and may trade on an exchange during the subscription period. This mechanism protects existing shareholders from dilution by giving them the first opportunity to maintain their proportional ownership.
Formula
TERP = (Market Cap Before + Proceeds from Rights Offering) / Total Shares After = (N x P + n x S) / (N + n)
N
Number of existing shares outstanding before the offering
P
Current market price per share before the offering
n
Number of new shares to be issued in the rights offering
S
Subscription price per new share (set at a discount to P)
How Rights Offerings Work
Existing shareholders get the right to buy new shares at a discount
Record Date
Company sets a date; all shareholders on record receive rights
1 right per existing share owned
Rights Distributed
Each shareholder receives transferable rights (can sell or exercise)
Rights trade on the exchange during the offering period
Subscription Period
Shareholders decide: exercise rights, sell them, or let them expire
Typically 16-30 days to decide
Exercise & Settlement
Exercising shareholders pay the subscription price, receive new shares
New shares issued; capital raised by company
Key benefit: Rights offerings allow existing shareholders to maintain their proportional ownership (avoid dilution) by participating. If they choose not to, they can sell the rights to recoup some value.
TERP Calculation

TERP = (Existing Shares x Price + New Shares x Sub. Price) / Total Shares

Subscription Scenarios
Full vs partial exercise and the dilution impact
Full Subscription
All shareholders exercise their rights
No dilution for any shareholder; company raises maximum capital
Partial Subscription
Shareholder B does not exercise; A and others do
B is diluted; A and others increase ownership proportionally
Key takeaway: Rights offerings are anti-dilutive only if shareholders exercise. Those who don't participate get diluted, but can sell their rights to partially offset the value loss.
Mechanics of a Rights Offering
The company announces a record date, and shareholders as of that date receive rights based on their holdings. Each right entitles the holder to buy a specified number of new shares at the subscription price, which is set below the current market price to incentivize participation. The subscription period typically lasts 2-4 weeks, during which shareholders can exercise, sell, or let their rights expire. An oversubscription privilege may allow participating shareholders to buy additional shares not taken up by others.
Theoretical Ex-Rights Price (TERP)
TERP is the theoretical market price of a share after the rights offering is completed, assuming all rights are exercised. It is calculated as the weighted average of the pre-offering market price and the subscription price, weighted by the number of old and new shares. TERP represents the equilibrium price at which neither exercising nor selling the rights creates a windfall. Understanding TERP is essential for evaluating whether the rights offering terms are fair.
Dilution Impact
Shareholders who exercise their rights maintain their proportional ownership and experience no economic dilution. Shareholders who do not participate see their ownership percentage decrease as new shares are issued to those who do exercise. The value of the right compensates non-participating shareholders for this dilution — they can sell their rights in the market to offset the loss. The diluted share count increases by the number of new shares issued, affecting per-share metrics like EPS.
Rights Offerings vs. Other Equity Raises
Unlike a secondary offering or PIPE, a rights offering gives existing shareholders the first opportunity to participate, protecting them from dilution. Rights offerings are more common in European and Asian markets and for financial institutions needing to raise regulatory capital. They take longer to complete than PIPEs but are perceived as more shareholder-friendly. Companies in distress sometimes use deeply discounted rights offerings to ensure full subscription.
Worked Example — With Real Numbers
A company has 100M shares trading at $40 ($4B market cap) and wants to raise $500M through a rights offering at $25 per share. It will issue 20M new shares ($500M / $25). TERP = (100M x $40 + 20M x $25) / (100M + 20M) = ($4B + $500M) / 120M = $37.50. Each right has a theoretical value of $37.50 - $25 = $12.50. A shareholder with 100 shares receives rights to buy 20 new shares. If they exercise, they invest $500 (20 x $25) and hold 120 shares worth $4,500 (120 x $37.50), preserving their proportional ownership.
Key Takeaways
Rights offerings give existing shareholders the first right to buy new shares at a discount
TERP is the theoretical post-offering price and equals the weighted average of old and new share prices
Shareholders who fully exercise their rights experience no economic dilution
Non-participating shareholders can sell their rights to offset dilution impact
Rights offerings are more common in European markets and for banks raising regulatory capital
Common Mistakes in Interviews
Assuming all shareholders will exercise their rights — some will sell or let them expire
Confusing the subscription price with TERP — TERP will always fall between the market price and subscription price
Forgetting that the value of a right offsets dilution for non-participating shareholders who sell their rights
Ignoring the oversubscription privilege, which allows participating shareholders to buy unexercised shares
How Interviewers Test This
If asked to calculate TERP, remember it is simply the total market cap after the offering divided by the total shares after the offering. Walk through the math step by step and note that TERP will always be lower than the pre-offering price but higher than the subscription price. Emphasize that rights offerings protect existing shareholders from forced dilution.
