A stock rights offering is a fundraising move in which a publicly traded company gives its existing shareholders the first chance to buy newly issued shares at a discount to the current market price. If you own shares on the record date, rights land in your brokerage account and you have a short window — usually 16 to 30 days — to do one of three things: exercise them and buy the discounted shares, sell them if they’re transferable, or let them expire and lose the value entirely.
How a Rights Offering Works
The company sets a subscription price below the current trading price and issues rights to current shareholders in proportion to their holdings. Proceeds might go toward paying down debt, funding an acquisition, or repairing the balance sheet. Because the shares go only to existing owners, participating shareholders can hold their ownership percentage steady even as the total share count grows.
The single most important thing to check when you receive a rights notice is whether the rights are transferable. In a transferable (sometimes called “renounceable”) offering, the rights trade separately on the exchange under a temporary ticker symbol, and you can sell them. In a non-transferable offering, you cannot sell or give them away; if you don’t exercise, they expire worthless. That distinction determines what choices you actually have.
The Three Numbers That Define the Offer
Every offering is built around three terms:
- Subscription price. The fixed price per share you’ll pay if you exercise. It’s almost always set at a meaningful discount to the market price.
- Subscription ratio. The number of rights needed to buy one new share. You typically get one right for each share you already own. A 5:1 ratio means five rights buy one new share.
- Expiration date. The deadline to exercise or sell. Most offerings run roughly 16 to 30 days from distribution.
Who Gets the Rights and When
The company announces a record date, which is the cutoff for eligibility. Only shareholders on the company’s books at the close of business on that date receive rights.
The ex-rights date is when the stock starts trading without the attached right. Since U.S. markets moved to T+1 settlement in May 2024, the ex-rights date now falls on the record date itself rather than two business days earlier, as it did under the old T+2 cycle.1U.S. Securities and Exchange Commission. SEC Chair Gensler Statement on Upcoming Implementation of T+1 Buy the stock on or after the ex-rights date and you won’t receive rights, because your trade won’t settle in time to put you on the shareholder register by the record date. A seller who parts with the stock during that window keeps the rights.
Once distributed, the rights show up in your brokerage account. Transferable rights begin trading under a temporary ticker. The period before the ex-rights date is called “cum-rights” because the stock and the right trade as a package; after the ex-rights date, the stock price typically drops by roughly the value of the detached right.
What a Right Is Worth
The theoretical value of a right depends on the gap between the market price and the subscription price, and on how many rights it takes to buy one new share. There are two versions of the formula.
During the cum-rights period, the stock price still includes the embedded value of the right:
(Market Price − Subscription Price) ÷ (Rights Needed per Share + 1)
After the ex-rights date, the stock trades without the right, so drop the extra “1”:
(Market Price − Subscription Price) ÷ Rights Needed per Share
Example: a stock trades at $50 during the cum-rights period, the subscription price is $40, and four rights are needed to buy one new share. Cum-rights value is ($50 − $40) ÷ (4 + 1) = $2 per right. When the stock goes ex-rights and drops to around $48, the ex-rights value is ($48 − $40) ÷ 4 = $2 per right. In an efficient market, both formulas produce roughly the same number.
Your Choices as a Shareholder
Exercise the Rights
Exercising means paying the subscription price for the new shares. You submit the required rights and payment through your broker or the company’s subscription agent, and you receive fully paid shares with the same voting and dividend rights as your existing stock. Exercising protects your ownership percentage from dilution, but it requires committing additional capital. The discount only helps if the company’s long-term prospects justify the investment.
Sell the Rights
If the rights are transferable, you can sell them on the open market like any other security. Selling monetizes the discount without putting up new money. It fits when you don’t have cash to exercise, don’t want a larger position, or would rather take the proceeds. The market price will hover near the theoretical value, though supply and demand can push it above or below as expiration approaches.
Let Them Expire
Doing nothing is the worst outcome. A right has a calculable market value from the moment it’s issued, and letting it expire is no different from tearing up a check. You lose both the discount and the cash you could have collected by selling, and your ownership percentage shrinks because everyone who exercised now holds a larger slice. Brokerages sometimes send reminders, but the responsibility is yours.
Ask for More Through the Oversubscription Privilege
Many offerings include an oversubscription privilege that lets shareholders who fully exercised their primary rights request additional shares from the pool left behind by non-participating investors. It isn’t guaranteed. If demand exceeds the leftover supply, the extra shares are distributed proportionally among everyone who requested them.
What Dilution Looks Like If You Don’t Participate
When a company issues new shares, the earnings spread across a bigger pool of stock, so earnings per share drops mechanically even if total earnings don’t change. Shareholders who exercise offset the hit with the new shares they bought; shareholders who sell offset it with cash. Shareholders who let their rights expire absorb the full effect: lower earnings per share, a smaller ownership percentage, and reduced voting power. The discount in the subscription price exists to compensate for that dilution, which is why ignoring the offering costs real money.
Tax Treatment
Receipt Usually Isn’t Taxable
Receiving rights in a standard offering is generally not a taxable event. Federal tax law excludes distributions of a corporation’s own stock or stock rights from gross income, subject to some exceptions.2Office of the Law Revision Counsel. 26 USC 305 – Distributions of Stock and Stock Rights The main exception: if the company offers you a choice between the rights and a cash dividend, the distribution is taxed as ordinary income at fair market value. In most rights offerings, no such choice exists, and you owe nothing until you exercise or sell.
Cost Basis and the 15% Rule
When you receive nontaxable rights, you need to determine their cost basis for future tax calculations. The rule turns on how the value of the rights compares to the value of your existing stock on the distribution date.3Office of the Law Revision Counsel. 26 USC 307 – Basis of Stock and Stock Rights Acquired in Distributions
- If the rights are worth less than 15% of the stock’s value, their basis is automatically zero and your existing stock’s basis stays intact. You can elect to allocate basis between the old stock and the new rights if it benefits you.
- If the rights are worth 15% or more of the stock’s value, you must allocate your original stock’s basis between the stock and the rights, proportionally by fair market value on the distribution date.
The election for rights under 15% must be made on the return for the year you received the rights, and it’s irrevocable.3Office of the Law Revision Counsel. 26 USC 307 – Basis of Stock and Stock Rights Acquired in Distributions It generally makes sense when you plan to sell rather than exercise, because a higher basis means a smaller taxable gain on the sale.
If You Exercise
The cost basis of your new shares equals the subscription price plus whatever basis was allocated to the rights. If the rights had a zero basis, your basis in the new shares is simply the subscription price. Exercise itself isn’t a taxable event; tax is deferred until you sell the new shares.
If You Sell the Rights
Selling triggers a capital gain or loss equal to the sale proceeds minus the allocated basis of the rights (which may be zero). Report the transaction on Form 8949 and carry the totals to Schedule D of Form 1040.4Internal Revenue Service. About Form 8949, Sales and Other Dispositions of Capital Assets With a zero basis and no election, the entire sale price is taxable gain.
Holding Period
Whether a gain or loss is long-term or short-term depends on how long you held the original stock, not the rights. When the basis of the rights is set under the Section 307 allocation rules, the holding period of the rights includes the time you held the underlying stock before the distribution.5Office of the Law Revision Counsel. 26 USC 1223 – Holding Period of Property Own the stock for three years, sell the rights two weeks after receiving them, and the gain qualifies as long-term.
For shares acquired by exercising, the holding period restarts on the exercise date. Those shares have to be held more than a year from exercise to qualify for long-term capital gains treatment, regardless of how long you held the original stock.
SEC Registration and the Prospectus
A domestic company conducting a rights offering must register the new shares with the SEC before distributing them. Eligible companies — including those with at least 12 months of SEC reporting history and no material debt defaults — can use the streamlined Form S-3.6U.S. Securities and Exchange Commission. Form S-3 Registration Statement Companies that don’t qualify file the more detailed Form S-1. Either registration statement discloses the terms of the offering, how the proceeds will be used, and the risks involved. Read the prospectus before deciding, because it tells you exactly why the company needs the money.
