Here's a classic market story: a company reports earnings that beat expectations, but its stock goes down. That's what happened to Carnival Corporation & plc (CCL) and Carnival plc (CUK) on Friday. The cruise giant delivered a record first quarter, but investors decided to focus on the company's lowered forecast for the full year instead.

For the quarter, Carnival posted adjusted earnings per share of 20 cents, topping the 18-cent estimate. Revenue came in at $6.165 billion, up 6.1% from a year ago and also beating expectations. On a GAAP basis, diluted EPS was 19 cents. The company swung to a net income of $258 million, a nice turnaround from a loss of $78 million in the same period last year. Adjusted net income was $275 million, and adjusted EBITDA hit a first-quarter record of $1.267 billion.

CEO Josh Weinstein noted the results "exceeded our guidance" even after absorbing a $54 million hit from higher fuel prices and currency exchange rates. The underlying business looked healthy. Gross margin yields jumped nearly 10%, and net yields in constant currency rose 2.7%, beating the company's own forecast by more than a percentage point.

On the cost side, cruise costs per available lower berth day increased 4.9%, while adjusted costs excluding fuel rose 5.3%—both figures came in better than guidance. The company also managed to reduce fuel consumption per berth day by 4.7%.

Demand doesn't seem to be a problem. Bookings for the full 2026 year are up by double digits, with nearly 85% of inventory already spoken for. Customer deposits hit a first-quarter record of nearly $8 billion, up almost 10% from a year ago. Liquidity improved, with operating cash flow of $1.263 billion and cash and equivalents totaling $1.424 billion, though total debt remains substantial at $25.290 billion.

So, with all that good news, why did the stock drop? The answer is in the guidance. For the current second quarter, Carnival expects adjusted EPS of about 34 cents, which is below the 42-cent estimate. More importantly, for the full 2026 year, the company lowered its adjusted EPS outlook to about $2.21. That's down from its previous guidance of $2.48 and below the consensus estimate of $2.36.

Weinstein tried to frame it positively, saying the strong first quarter "supported an increase to our full year operational outlook of nearly $150 million, helping to mitigate the impact of higher fuel prices." But the math on the bottom line tells a different story for investors.

Perhaps to soften the blow, Carnival also announced a new $2.5 billion share repurchase program and introduced its long-term "PROPEL 2029" targets. But on the day, the market's reaction was clear: shares of Carnival were down 3.82% at $24.31. Sometimes, it's not about how you started the race, but where you tell people you're going to finish.
