Tamar Petroleum Ltd engages in the exploration, development, production, marketing, and transmission of natural gas and condensate from offshore reservoirs in Israel. The company holds a 16.75% interest in the Tamar and Dalit leases, located in the Mediterranean Sea west of Haifa; it supplies natural gas primarily to the Israel Electric Corporation, private power producers including Rotem OPC, Dorad and Dalia, Bazan Oil Refineries, Dead Sea Works, and industrial customers such as Phoenicia Flat Glass Industries, Hadera Paper, and Shaniv Paper Industries; it also exports natural gas to Jordan and Egypt and sells condensate to Paz Ashdod Oil Refineries. Tamar Petroleum operates exclusively in Israel, with production from the Tamar reservoir--which commenced in 2013--supporting approximately 50% of the country's electricity generation needs through output exceeding 30 million cubic meters per day. Founded in 2015 and headquartered in Herzliya Pituach, the company--formerly Karish and Tanin Management Ltd--went public on the Tel Aviv Stock Exchange in July 2017 under ticker TMRP.TA following a $980 million bond and equity raise. Recent developments include Azerbaijan's SOCAR completing its acquisition of a 10% effective stake in the Tamar field from Aaron Frenkel-controlled entities in June 2025 for $1.25 billion, elevating SOCAR's indirect holdings via stakes in Tamar Petroleum and Union Energy; Frenkel subsequently increased his direct stake in Tamar Petroleum to approximately 15.8% in September 2025 through purchases totaling NIS 498 million, while granting SOCAR a two-month option to acquire half of those shares.
