Baidu, Inc. (NASDAQ:BIDU) furnished a Form 6-K on September 29, 2026 that consists of a single exhibit: a Next Day Disclosure Return dated September 28, 2026, originally prepared for the Hong Kong Stock Exchange. The return reports that Baidu bought back 583,700 of its Class A ordinary shares on September 28, 2026 for HK$49,996,356.54, and it updates the running total of shares repurchased under a mandate approved by shareholders on August 26, 2026.

What the Return Reports

The return relates to Baidu's weighted voting rights ordinary shares listed on the Main Board of the Hong Kong Stock Exchange under stock code 09888, and the instrument type is Class A ordinary shares. The repurchase on September 28 was made on the exchange, at prices ranging from HK$85.05 to HK$86.60 per share, for the total of HK$49,996,356.54, or roughly HK$50 million.

Under the repurchase mandate approved on August 26, 2026, Baidu has repurchased 8,996,300 shares in total during the period from September 7 to September 28, 2026. The return states that this represents 0.329 percent of the issued shares as of the mandate date. The mandate authorizes repurchases of up to 273,356,149 shares, so the cumulative repurchases reported so far are a fraction of the authorized amount. Simple arithmetic on the figures in the return gives an average price of about HK$85.65 per share for September 28, and shows that day's purchases were about 6.5 percent of the cumulative total. These are calculations, not figures stated in the filing.

Why a U.S. Filer Furnishes a Hong Kong Form

Baidu is a company incorporated outside the United States that files annual reports on Form 20-F, and it lists in both Hong Kong and the United States. As a foreign private issuer, it furnishes on Form 6-K information that it has made public under its home or listing-venue rules. The Next Day Disclosure Return is a Hong Kong regulatory form, code FF305, that an issuer publishes by the next trading day after certain share transactions, including repurchases.

The 6-K itself is short. It identifies the exhibit, gives Baidu's business address in Beijing, and is signed on behalf of the company by Haijian He, Chief Financial Officer, on September 29, 2026. The exhibit is signed by Lin Juan, Joint Company Secretary. The return is marked as a new submission.

Confirmations in the Return

In the return, the company confirms that all repurchases complied with the applicable listing rules. It also states that there have been no material changes to the particulars contained in the Explanatory Statement dated July 27, 2026, the document sent to shareholders in connection with the repurchase mandate.

The return also refers to a restriction on further issuances. It notes a moratorium period that applies through October 28, 2026, during which new share issuances or sales of treasury shares are restricted without approval from the exchange. The filing presents this as a compliance detail and does not announce any plan to issue shares.

The return is a compliance record and gives no explanation of Baidu's reasons for the repurchases, and it does not discuss business results, share price levels or future repurchase plans.

Baidu Mandate Count Stands at 8,996,300 Shares

Returns of this kind are filed by the next trading day after each repurchase while the mandate is in use. Each would update the cumulative count, currently 8,996,300 shares, against the 273,356,149-share limit.

The moratorium through October 28, 2026 is the one dated item in the return.
