Amendment No. 5 to Schedule 13D

This Amendment No. 5 (this “Amendment”) amends the Schedule 13D filed by Photon Group Limited, a British Virgin Islands corporation (“Photon”), with the Securities and Exchange Commission (the “SEC”) on June 16, 2004, as amended by Amendment No. 1 filed with the SEC on April 1, 2010 (“Amendment No. 1”), by Amendment No. 2 filed with the SEC on July 8, 2011 (“Amendment No. 2”), by Amendment No. 3 filed with the SEC on April 10, 2017, and by Amendment No. 4 filed with the SEC on June 8, 2018 (“Amendment No. 4”). The original Schedule 13D of Photon, as amended by Amendment No. 1, Amendment No. 2, Amendment No. 3, and Amendment No. 4, is hereinafter referred to as the “Initial Statement.”

Item 3 of the Initial Statement is supplemented as follows:

The following are transactions by Photon in ordinary shares, par value $0.001 per share (“Ordinary Shares”), of Sohu.com Limited, a Cayman Islands company (the “Issuer”), that have occurred since the filing of the Initial Statement:

The 8,798,279 Ordinary Shares held by Photon include 25,000 ADSs representing Ordinary Shares that were issued to Photon in exchange for 25,000 shares of the common stock of Sohu.com Inc., of which the Issuer is the successor issuer, that were purchased by Photon on May 12, 2017 for a price of $40.06 per share, but that were inadvertently reported in an Amendment to Schedule 13D filed by Dr. Charles Zhang on May 30, 2017, and in subsequent amendments to that Schedule 13D, as acquired and held directly by Dr. Zhang, and were not reported by Photon as held by it.

Item 4 of the Initial Statement is hereby supplemented as follows:

Photon made the Purchases for investment purposes.

Item 5 of the Initial Statement is hereby amended and restated to read in its entirety as follows:

As of the date of this Amendment, Photon beneficially owns 8,798,279 Ordinary Shares.

Percent of Class:             22.6%

The foregoing percentage is calculated based on 38,933,038 Ordinary Shares of the Issuer outstanding as of May 31, 2018 as reported in the Issuer’s Form 6-K submitted to the SEC on May 31, 2018.

See Item 3.
