SAN FRANCISCO — Uber plans to set a price range for its initial public offering that would value it at as much as $90 billion, a person with knowledge of the situation said on Thursday, in a sign of caution amid a flood of highly hyped tech offerings.

The world’s largest ride-hailing company, Uber plans to offer its shares to investors for $44 to $50 each, putting its total valuation between $80 billion and $90 billion, said this person, who was not authorized to speak publicly.

In that range, Uber would fall short of the $100 billion valuation that it would have reached based on earlier pricing it shared with some investors, though it would still be above the $76 billion it was appraised at in its most recent private fund-raising in August.

Lyft, Uber’s chief rival in the ride-hailing industry, got off to a turbulent start in public markets. In the weeks since Lyft’s shares began trading, they have skidded below their offering price, making it more of a challenge for Uber to pitch itself to investors.
