ZTO · ZTO Express (Cayman) Inc.

This 6-K filing discloses ZTO Express’s monthly share capital activity for March 2026, centered on two discrete share repurchase and cancellation events affecting only its listed Class A Ordinary Shares. The first event involved 7,373,076 Class A shares — represented by an equivalent number of American Depositary Shares — repurchased from the NYSE between February 10–27, 2026, and formally cancelled on March 11, 2026. The second event comprised 18,254,400 Class A shares repurchased concurrently with the February 4, 2026 offering of convertible senior notes and cancelled on March 16, 2026. Critically, all repurchased shares were cancelled outright — none were retained as treasury shares — meaning the reduction is permanent and directly lowers the denominator for earnings per share calculations. While no dividend or new buyback authorization is disclosed, the execution of these cancellations reflects active capital return discipline aligned with prior board approvals (e.g., General Meeting approval dated June 17, 2025). The filing also confirms ongoing compliance with HKEX public float rules for Class A shares, reinforcing listing stability. No changes occurred to Class B shares or undesignated shares, and no new debt issuance, equity grants, or executive changes are reported — limiting the scope of material impact to share count reduction and associated EPS implications.
