Kenon’s Subsidiary OPC Energy Ltd. Announces Private Placement of New Shares

Singapore, March 13, 2026. Kenon Holdings Ltd.’s (NYSE: KEN, TASE: KEN) (“Kenon”) subsidiary OPC Energy Ltd. (“OPC”) announced a private placement of 8,000,000 new ordinary shares to institutional investors in Israel for gross proceeds of approximately NIS 800 million (approximately $257 million), at a price of NIS 100 per share. The closing price of OPC’s ordinary shares on March 12, 2026 was NIS 105.7.

OPC indicated that the new shares to be issued in this private placement will constitute approximately 2.7% of OPC’s issued and outstanding shares before giving effect to the private placement. The private placement is subject to approval of the Tel Aviv Stock Exchange for listing of the new shares.

Following completion of OPC's private placement, Kenon is expected to hold approximately 46% of OPC’s ordinary shares.

The OPC ordinary shares referenced in this press release have not been registered under the Securities Act of 1933, and may not be offered or sold in the United States absent registration or an applicable exemption from registration requirements under that act.
