Says investors underestimate potential obstacles to Tesla-SpaceX merger. Rajat Gupta, an analyst at the bank, said that although a merger between Tesla and SpaceX "looks reasonable on paper", the current speculation surrounding the merger underestimates the potential obstacles to the transaction.

Gupta said that the merger will allow CEO Elon Musk to "merge the vision, mission and engineering leadership of the two platforms" and that the two companies' shared artificial intelligence ambitions will become a "potential strategic glue." However, the analyst said potential obstacles include multi-jurisdictional regulatory approvals; governance and

voting rights symmetry; and "perceptions that the merger will be an SPCX-led acquisition rather than a merger of equals." "Overall, we will be watching SPCX's acquisition currency, regulatory landscape, and Musk's voting power in Tesla as catalysts as a potential merger approaches," he added.

JPMorgan Chase said that if the deal occurs, the most likely structure will be an all-stock acquisition of Tesla led by SpaceX, and Gupta said that this transaction structure may best bridge the valuation gap and avoid large-scale cash expenditures. Gupta has a neutral rating on Tesla and a $475 price target.
