Hesai Group (NYSE: HSAI) enacts 1-for-8 share subdivision and updates ADS ratio

Rhea-AI Filing Summary

Hesai Group implemented a 1-for-8 subdivision of its issued and unissued Class A and Class B ordinary shares, effective before the commencement of trading on The Stock Exchange of Hong Kong Limited on July 10, 2026. Each ordinary share was subdivided into eight ordinary shares. After this Share Subdivision, authorized share capital is US$100,000, divided into 8,000,000,000 ordinary shares with a par value of US$0.0000125 each, comprising 400,000,000 Class A ordinary shares and 7,600,000,000 Class B ordinary shares. Simultaneously, an ADS Ratio Change became effective so that each American depositary share now represents eight Class B ordinary shares, instead of one previously. Because the ADS ratio change matched the share split, no new ADSs were issued and the total number of outstanding ADSs remains the same.

Insights

Equity Capital Markets Analyst

Hesai executes a proportional share split and ADS ratio change with no economic dilution.

The company completed a 1-for-8 subdivision of its Class A and Class B ordinary shares and adjusted its American depositary share (ADS) ratio so each ADS now equals eight Class B shares. The change primarily affects trading convenience and share price optics rather than underlying value.

Authorized capital is now US$100,000, divided into 8,000,000,000 ordinary shares at a par value of US$0.0000125 each, split between 400,000,000 Class A and 7,600,000,000 Class B shares. Because the ADS ratio change is exactly proportionate to the share split, the number of outstanding ADSs is unchanged, so holders' economic and voting interests are not altered by this action.

Share Subdivision financial

"approved a 1-to-8 share subdivision of the Company’s issued and unissued Class A ordinary shares"

A share subdivision, often called a stock split, increases the number of a company's shares by dividing existing shares into smaller pieces so each shareholder keeps the same ownership proportion. It matters to investors because it makes individual shares cheaper and can boost trading ease and liquidity—like cutting a pizza into more slices so each piece is smaller but the whole pizza remains the same—though it does not change the company's total value.

ADS Ratio Change financial

"the previously-announced change in the ratio of the Company’s American depositary share (“ADS”) to Class B ordinary share"

An ads ratio change is an adjustment to how many American Depositary Shares (ADS) represent one unit of a foreign company’s ordinary shares — like changing whether a cake is cut into 2 or 10 slices. Investors care because it alters the number of tradable ADS, the implied price per ADS and an investor’s ownership stake, which can affect liquidity, perceived value and comparisons of holdings across markets.

American depositary share financial

"each ADS now represents eight (8) Class B ordinary shares"

An American Depositary Share (ADS) is a U.S.-listed certificate that represents a specified number of shares in a foreign company, held by a custodian bank; it works like a receipt that allows U.S. investors to buy and trade foreign equity on American exchanges without dealing with another country’s markets. Investors care because ADSs make foreign stocks easier to access, improve liquidity and settlement in dollars, and can affect dividend payments, voting rights and regulatory oversight compared with buying the underlying foreign shares directly.

authorized share capital financial

"the Company’s authorized share capital is now US$100,000 divided into 8,000,000,000 ordinary shares"

The maximum number of shares a company is legally allowed to issue according to its governing documents. Think of it as the size of the blank checkbook a company keeps for selling ownership stakes: it sets an upper limit but does not mean all shares are in circulation. Investors care because a larger authorized amount makes it easier for the company to raise money or grant stock-based pay, which can dilute existing holdings and affect control and value per share.

Effectiveness of Share Subdivision and ADS Ratio Change

As previously announced, the shareholders of Hesai Group (the “Company”) approved a 1-to-8 share subdivision of the Company’s issued and unissued Class A ordinary shares and Class B ordinary shares with a par value of US$0.0001 each (the “Share Subdivision”) at the annual general meeting held on June 26, 2026.

Effective before the commencement of trading on The Stock Exchange of Hong Kong Limited on July 10, 2026, the Company subdivided each of its issued and unissued ordinary shares into eight (8) ordinary shares. Following the Share Subdivision, the Company’s authorized share capital is now US$100,000 divided into 8,000,000,000 ordinary shares with a par value of US$0.0000125 each, comprising (i) 400,000,000 Class A ordinary shares with a par value of US$0.0000125 each, and (ii) 7,600,000,000 Class B ordinary shares with a par value of US$0.0000125 each.

Simultaneously with the Share Subdivision, the previously-announced change in the ratio of the Company’s American depositary share (“ADS”) to Class B ordinary share (the “ADS Ratio Change”) also became effective. Following the ADS Ratio Change, each ADS now represents eight (8) Class B ordinary shares. Previously, each ADS represented one (1) Class B ordinary share.

Because the ADS Ratio Change was exactly proportionate to the Share Subdivision, no new ADSs were issued to any ADS holder and the total number of the Company’s outstanding ADSs remains unchanged.
