During the three months ended June 30, 2026, the Company recorded a $1.2 million reversal of previously recognized non-government revenue. The adjustment was driven by a change in assumptions connected to the Company’s constraint on variable consideration within certain milestone payments under the research and development technology license agreement (the “SK On R&D license”).
