Musk will have a tough time getting Tesla investors excited about SolarCity · CNBC

Elon Musk has won legions of fans with a string of successes that includes PayPal (PYPL), Tesla Motors (TSLA) and SpaceX. But even that resume may not comfort investors concerned about his latest radical idea.

Musk has proposed that his electric car developer Tesla acquire solar panel installer SolarCity (SCTY) for $2.8 billion. He's the principal stakeholder of both, but has disqualified himself from the talks and said the deal will require support from a majority of "non-me shareholders."

That could be a problem because there's a ton of overlap between the two investor groups, whose holdings in Tesla are worth many billions more than their stakes in SolarCity. While SolarCity shareholders should love this deal — it represents a premium of up to 35 percent above where the stock was trading on Monday — those same investors fear that a merger could wreck their Tesla shares.

Investors voting with their wallets will need answers before getting behind Musk, the celebrated tech entrepreneur. It's a classic battle between Silicon Valley idealism and Wall Street pragmatism.

"Musk may learn that engineering electrons is easier than engineering elections," said Joseph Grundfest, a law professor at Stanford University and senior faculty member at the Rock Center for Corporate Governance.

Tesla shares plunged 10 percent Wednesday to $196.66, following the Palo Alto, California-based company's offer to purchase SolarCity for $26.50 to $28.50 a share. SolarCity, based 15 miles north in San Mateo, rose 3.3 percent to $21.88, closing well below the bid price, suggesting that Musk faces plenty of skepticism from the public markets.

More than half of non-Musk shares in SolarCity are owned by investors who are also in Tesla. Those investors own roughly $950 million worth of SolarCity and $17 billion of Tesla, according to data from FactSet analyzed by CNBC.com.

Fidelity Management is the biggest institutional backer of both companies, owning 11 percent of Tesla and 15 percent of SolarCity. The Boston-based firm's Tesla stake is worth $3.2 billion, more than 10 times its SolarCity holdings and $1 billion more than SolarCity's total market capitalization.

A Fidelity spokesperson declined to comment.

Other big-name investors in both companies include Vanguard Group, Morgan Stanley Investment Management, BlackRock (BLK) Fund Advisors and CTC myCFO, an affiliate of BMO Harris.

In a conference call Wednesday, Musk called the deal a "no-brainer" because Tesla and SolarCity are working to power consumers' lives with solar. Tesla has the cars as well as the Powerwall, which stores energy collected from the sun, and SolarCity brings solar to the home through a novel distribution and financing model.
