July 26 (Reuters) - Shares of Lucid Group Inc rose as much as 8.6% in their Nasdaq debut on Monday after the electric vehicle maker completed its merger with a blank-check company backed by Wall Street dealmaker Michael Klein. The luxury electric vehicle maker, formerly known as Lucid Motors and run by ex-Tesla engineer, had agreed to go public in February through a merger with Churchill Capital Corp IV. The merger gave the combined company a pro-forma equity value of $24 billion.
