Cumulatively the forum has promoted 129 chips, of which 119 are in mass production, implying a mass-production rate of 92.2%.

Russian strikes late on June 1 into the early hours of June 2 killed 18 people in Ukraine — 6 in Kyiv and 12 in Dnipro — and caused power cuts in parts of Kyiv, Dnipropetrovsk, Donetsk, Sumy, Zaporizhia, Kharkiv and Cherkasy, the Ukrainian Energy Ministry said by midday June 2. Kyiv was hardest hit, with dozens of residential buildings and civilian facilities damaged and a local energy firm's production site affected; crews are working to restore supply. Ukraine's State Emergency Service has deployed more than 500 personnel. President Zelenskiy said the attacks underscore Ukraine's urgent need for US Patriot missile systems.
