What comes next for Upstart?

Upstart's fourth-quarter results weren't terrible, but guidance suggest that the business won't see meaningful performance improvements in the near term.

For this year's first quarter, Upstart expects sales to come in at roughly $125 million, representing an increase of roughly 21% year over year. On the other hand, sales for the period are still projected to decline roughly 14% on a sequential quarterly basis.

Meanwhile, the company expects to post an adjusted loss of $33 million in the period. The business posted an adjusted loss of $38.3 million in the prior-year period, but it's hard to get excited about the moderate improvement, given management's sales projection.

For comparison, Upstart sales of $310 million and adjusted net income of $58.6 million in Q2 2022. Investors were hoping to see stronger recovery this year, but it looks like that may not be in the cards. Management's guidance is raising concerns on Wall Street that the company's business may continue to struggle unless macroeconomic conditions are optimal.
