A Morgan Stanley analyst and Tesla bull teased a merger with SpaceX.

Tesla wouldn't gain any meaningful synergies from a tie-up, but its business would become more complicated.

CEO Elon Musk would avoid the hassles of having to run two high-pressure public companies.



Last year, Tesla merged with struggling SolarCity, making Elon Musk CEO of both companies. The tie-up hasn't hurt Tesla in 2017 as the company's stock has surged above $300 per share and the combined enterprise hit a market capitalization of over $50 billion.

That doesn't mean it wasn't a terrible deal. Tesla's balance sheet instantly became loaded up with SolarCity debt, and what had been primarily a carmaker was suddenly responsible for rolling out a new solar roof product, at a time when it should have been all-hands-on-deck to launch the Model 3 mass-market vehicle.

The Model 3 is woefully behind schedule at this point, and although the solar roof is compelling, The Solar City side of Tesla business isn't any more coherent than it was a year ago.

Musk is also CEO of SpaceX, and last week Morgan Stanley analyst Adam Jonas teased a merger with Tesla, arguing that such a deal would yield powerful synergies. The financial mechanics of how a SpaceX-Tesla merger would happen are both speculative and unclear; in July, SpaceX raised $350 million, bringing it valuation to $21 billion. An IPO has long been discussed.

Musk might not want to run two public companies

But maybe Musk doesn't want to be running another public company. He's expressed some exasperation with playing that role at Tesla, where investors have the carmaker under constant scrutiny and short sellers are always circling like sharks. SpaceX's mission is ultimately more ambitious than Tesla's — the whole go-to-Mars thing — and the company have been wowing the the space community by routinely launching and landing rockets.

Tesla doesn't have enough cash to buy SpaceX outright, so investors would have to accept a largely stock-based deal, and that might make sense to many of them: since its own 2010 IPO, Tesla shares have returned over 1,ooo%, and several analysts have said that the stock hundreds of dollars of upside potential from its current level.

Managerially, putting all the pieces of Musk's master plan — electric cars, solar power, space exploration — under one roof could ease the anxieties of anybody who thinks he's now stretched too thin.

Unfortunately, a Tesla-SpaceX merger would raise a major issue: unlike SolarCity, the company wouldn't be shifting a massive amount of debt to Tesla's balance sheet, but it would be shifting monumental risk. Space is dauntingly expensive when everything is going right but ruinously costly when things go wrong. That's why governments, for the most part, have been the only ones aiming for large-scale goals in the final frontier. Tesla-SpaceX would expose Tesla to colossal losses at a time when it's already posting record negative earnings.

There are some serious positives in a merger

On the positive side, Tesla would have access to SpaceX's goodwill with investors and the company's cash, around $1 billion. Nevertheless, Tesla balance sheet would become almost incomprehensible, as auto, energy, and aerospace analysts all struggle to figure out what the diverse conglomerate — with a theoretical $70-billion market cap — is worth. It's already a challenge to independently value the car, energy, and solar businesses (the default position is to kick solar and energy down the road and rightly ascribe almost all of Tesla's value to cars).

If Tesla gains from a SpaceX merger, it could be the deal of the decade. SpaceX investors would potentially receive a much fatter payout (if they think Tesla has tremendous long-terms prospects), and Musk would be able to neatly avoid the pressure to handle two rounds of quarterly financial reporting and a whole new batch of prognosticators and short-sellers.

On the other hand, merging with SpaceX could yield almost zero synergies — the car business and the aerospace industry might look similar but they're actually radically different — and add so much risk and volatility to Tesla already risky and volatile business that Tesla shares could get hammered and the company would see its access to capital reduced at precisely the wrong time.

I'm betting on a merger

If I were betting, I'd say that Tesla and SpaceX actually will merge, perhaps against some heavy SpaceX investors complaints. Tesla got away with it on SolarCity, Musk detests being the CEO of a public company, and SpaceX is really his baby. And Tesla stock has become a super currency, opening up all manner of financial options.

Finally, the long stock-market rally that we've experienced in the aftermath of the financial crisis can't last forever. Tesla got in early and has benefitted enormously. SpaceX might not be so lucky. The biggest risk to the company might be that despite its triumphs, it would be out there by itself nad subject to market forces that have nothing to do with its mission.

A merger with Tesla would save Musk from having to pull a SolarCity, Part Deux, and ride to rescue if SpaceX gets in trouble.
