Carnival's (CCL) fiscal Q2 earnings exceeded guidance and Street expectations due to better-than-expected cost controls, but the stock may be pressured by lower second half guidance tied to weaker net yield growth estimates, Truist Securities said in a report Tuesday.

Heading into fiscal Q2 earnings, many sell-side bulls expected the company to lift the net yield forecast, while Carnival reduced the full-year net yield growth guidance to about 3.2% from 4.1%, according to the note.

Carnival raised its full-year adjusted earnings per share guidance to $2.22 from $2.21, compared with Street consensus of $2.23, the note added.

For fiscal Q3, the company guided to adjusted earnings before interest, taxes, depreciation, and amortization of $2.89 billion and adjusted EPS of $1.35, falling short of Street estimates of $3.04 billion and $1.42, respectively, the brokerage said.

Truist kept a hold rating on Carnival with a price target of $29.
