Two analysts raised their price targets for NerdWallet on the solid report. KeyBanc's Justin Patterson bumped it to $18 per share from $16, while Barclays' Ross Sandler increased it to $21 per share from $16. Sandler said the "stellar" fourth-quarter results in a challenging market show that NerdWallet is standing out among its peers, reported the Fly.

Now what

The company issued guidance, calling for revenue to grow roughly 30% year over year to a range of $165 million to $170 million at the midpoint of the fiscal year. Adjusted earnings before interest, taxes, depreciation, and amortization (EBITDA) is expected to be in the range of $17 million $19 million, also a year-over-year increase.

This is a good little stock that has already become profitable in just two years as a public company. It has no outstanding debt and seems to be executing on its strategy to expand its verticals and integrate them. Keep an eye on it.
