Elon Musk can walk away from his $44bn takeover of Twitter for just $1bn — less than 1 per cent of his net worth and a fraction of the $21bn of the equity he has committed to complete the acquisition of the social media group.

The “reverse termination fee”, revealed in a regulatory filing by Twitter on Tuesday, is a significantly lower penalty than the typical leveraged buyout.

The precise terms of the potential penalty had been hotly awaited on Wall Street after Musk said he would fund the Twitter takeover with $13bn of debt, as well as a $12.5bn loan secured against his Tesla stake and a pledge to finance the remaining $21bn of equity himself.

Doubts about how Musk would fund his Twitter acquisition helped drive down Tesla shares yesterday. Stock in the electric car company, where Musk is chief executive and a major shareholder, fell more than 12 per cent, wiping $125bn off the value of the company and more than $10bn from the billionaire’s personal net worth. The sell-off came a day after Musk clinched the support of the Twitter board to take the social media platform private.

Shares in Tesla have dropped 19 per cent since Musk became Twitter’s largest shareholder more than three weeks ago. Meanwhile, Twitter shares continue to trade below Musk’s $54.20 offer price, indicating investors are unsure the deal will be completed. Yesterday they closed at $49.68.

What else we’re reading

How to avoid a recession A paper by Alex Domash and Larry Summers pointed out that, since 1955, there have been eight instances where US wage inflation was above 5 per cent and the unemployment rate was below 4 per cent, as they are now. In all eight, a recession followed within two years. History is not destiny, though, writes Robert Armstrong.

The pandemic that American politics forgot The loss of nearly 1mn lives in America from Covid-19 has barely registered with domestic voters. There has been no electoral realignment, no intellectual rupture of the kind that followed the Opec oil crisis and no passing of the torch to a new political generation. Two explanations stand out for this curious state of affairs, writes Janan Ganesh.
