Costco Declares $30 Special Dividend: Key Dates for Investors

Key takeaways

• Costco declared a one-time $30-per-share special cash dividend, with a total payment of about $13.3 billion.

• The payment date is December 4, 2026; the company says shareholders must be of record at the close of business on November 24, 2026.

• Costco also reauthorized up to $4 billion in stock repurchases through November 2030. Existing shareholders should check the dates and eligibility details with their broker rather than treating the announcement as a reason to buy the stock.

Costco announced the special dividend on November 10, 2026. The retailer says it will pay $30 for each eligible common share on December 4 to shareholders of record on November 24, while a renewed buyback authorization gives the company another way to return capital to shareholders.

What did Costco announce on November 10?

Costco Wholesale said its board declared a special cash dividend of $30 per common share. The company estimates the total payment at approximately $13.3 billion. The payment is scheduled for December 4, 2026, and the stated record date is November 24, 2026.

The announcement is in Costco’s investor-relations release. Investing.com’s coverage independently reports the same per-share amount, dates and estimated total.

The board also reauthorized a common-stock repurchase program of up to $4 billion. It will expire in November 2030 and replaces a previous $4 billion authorization adopted in 2023 and due to expire in January 2027. Costco said it had purchased $3.1 billion of shares under that earlier program.

These are two different ways to return capital. A dividend distributes cash to eligible shareholders. A repurchase program authorizes the company to buy its own shares, but the authorization does not mean Costco will immediately spend the full amount.

Why does the $30 payment matter?

Analysis: The headline figure is large because it combines a substantial per-share payment with a broad shareholder base. At the announced rate, an investor with one eligible share would receive $30 before any applicable taxes; 10 eligible shares would mean $300, and 100 would mean $3,000.

The $13.3 billion estimate is the company’s stated total cost, not a forecast of what an individual investor will receive. The actual gross payment to a shareholder depends on the number of eligible shares held.

The buyback authorization adds a second capital-return tool, but it should not be confused with a cash payment to every shareholder. A company can repurchase shares over time, and the board’s authorization sets a ceiling rather than a guaranteed timetable or spending commitment.

Neither action guarantees that Costco’s share price will rise. A dividend is only one part of an investment’s return, and stock prices can move down as well as up. Investors should consider the company, the share price and their own portfolio rather than judging a stock by a special dividend alone. The SEC’s Investor.gov stock guide explains that shareholders may receive dividends but can still lose money when share prices fall.

What should Costco shareholders do now?

If you already own Costco shares, use the company’s dates as a prompt to check your account—not as a reason to make a rushed trade.

• Check your holdings. Confirm the number of Costco common shares in your brokerage or other account and review the account’s dividend settings.

• Confirm eligibility with your broker. Costco’s release identifies November 24 as the record date, but it does not state an ex-dividend date. Ask your broker which trading date determines whether a purchase qualifies; do not assume that buying on the record date is sufficient.

• Estimate the gross payment. Multiply the number of eligible shares by $30. This is a pre-tax estimate, not a guarantee of the final amount credited to your account.

• Review tax treatment. The company’s announcement does not explain how the payment will be classified for every investor. Tax treatment can depend on holding period, account type and personal circumstances; consult a qualified tax professional if the amount is material.

• Avoid a dividend-only trade. Buying a share solely to collect a distribution does not remove market risk. The share price can change, and the company has not promised an investment return.

For example, 25 eligible shares would produce a gross special-dividend payment of $750. That simple calculation does not include taxes, fees or any movement in the stock price.

What is still unknown?

Costco’s November 10 release does not state the ex-dividend date, the tax classification of the payment for individual shareholders, or how the company will fund the special dividend. It also does not give a schedule for purchases under the newly authorized buyback.

Those details matter. The record date tells investors which shareholders the company intends to pay, while the ex-dividend date is the market date used to determine whether a stock buyer receives an upcoming dividend. Investors should rely on a confirmed exchange or broker notice for that trading detail, not infer it from the record date alone.

The next firm dates in Costco’s announcement are November 24, 2026, for the shareholder record and December 4, 2026, for payment. Watch for any subsequent company or exchange notice that clarifies trading eligibility.

Costco’s special dividend: frequently asked questions

How much is Costco paying per share?

Costco declared a special cash dividend of $30 for each eligible common share. The company estimates the total payment at approximately $13.3 billion.

When will Costco pay the special dividend?

The payment is scheduled for December 4, 2026. Costco says shareholders must be of record at the close of business on November 24, 2026.

Does the $30 dividend mean Costco stock is a guaranteed buy?

No. A dividend does not guarantee a gain, and it does not protect an investor from a falling share price. Consider the stock’s risks and your own investment goals rather than buying only to pursue the payment.

Is the new $4 billion buyback the same as the dividend?

No. The special dividend is a cash distribution to eligible shareholders. The buyback is authorization for Costco to repurchase up to $4 billion of its own shares through November 2030; it is not a $4 billion cash payment to shareholders.

Has Costco announced the ex-dividend date?

The November 10 company release gives the November 24 record date but does not state an ex-dividend date. Check a confirmed notice from your broker or the relevant exchange before making a trade based on dividend eligibility.

Bottom line

Costco has declared a $30 special dividend per eligible share, payable December 4, 2026, with a November 24 record date, and renewed a separate buyback authorization of up to $4 billion. Current shareholders should confirm the ex-dividend date and eligibility with their broker, then consider the payment alongside the risks of owning the stock—not as a stand-alone reason to buy.
