EXPLANATORY NOTE
This Post-Effective Amendment No. 1 amends the Registration Statement on Form S-3
(Registration No. 333-109410) (the “Registration Statement”) on which Sina Corporation (the
“Registrant”) registered $100,000,000 of zero coupon convertible subordinated notes due 2023 and
3,877,471 ordinary shares, par value $0.133 per share, of the Registrant (the “Securities”) to be
offered and sold by certain selling securityholders of the Registrant described in the Registration
Statement (the “Selling Securityholders”).
The Securities and Exchange Commission declared the Registration Statement effective on
January 2, 2004. As of the date hereof, the Registrant believes that $2,000,000 of the Securities
covered by the Registration Statement have not been sold by the Selling Securityholders. The
Registrant had an obligation pursuant to a registration rights agreement to maintain the
effectiveness of the Registration Statement only until January 2, 2006 and desires that the
Registration Statement no longer be considered effective with respect to any unsold Securities.
Accordingly, this Post-Effective Amendment is being filed to deregister all unsold Securities.
SIGNATURE
Pursuant to the requirements of the Securities Act of 1933, the registrant has duly caused
this registration statement to be signed on its behalf by the undersigned, thereunto duly
authorized, in the City of Beijing, China, on April 14, 2006.
