The ride-hailing company’s market debut, which is set for tomorrow, has become “an exercise in dialing back expectations,” write Michael de la Merced and Mike Isaac of the NYT. Uber’s I.P.O. may now value it at only $86 billion based on a share price of $47. According to unidentified sources, the company plans to price its offering at or below the midpoint of its announced range: $44 to $50. “That would be well below the $100 billion that Uber had forecast to some of its investors,” Mr. de la Merced and Mr. Isaac write.
