Travel review website TripAdvisor (NASDAQ: TRIP) reported lower-than-expected quarterly revenue for the fourth quarter of its fiscal year. TripAdvisor reported total revenue of $316 million for the fourth quarter, missing the average estimate of $326.5 million, according to analysts polled by Thomson Reuters.

Net income fell to $1 million, or 1 cent per share, in the quarter, from $3 million, or 2 cents per share, a year earlier. Adjusted net income fell nearly two-thirds to $23 million. On an adjusted basis, the company earned 16 cents per share, lower than the analysts’ estimate of 31 cents per share.

TripAdvisor aggregates reviews and opinions about destinations and hotels and owns websites such as TripAdvisor.com and Oyster.com. The company has 1.06 million hotels, 4.3 million restaurants, 835,000 vacation rentals, and 760,000 attractions and experiences listed within its information base. TripAdvisor received 465 million reviews and opinions and 390 million monthly unique users during last year’s summer travel season.

The company’s quarterly results were hurt by a drop in subscription revenue and a decline in display advertisements on its websites. Revenue from display-based advertising and subscriptions declined 2.8 percent to $69 million.

The non-hotel segment provided all of TripAdvisor’s revenue growth for the quarter, rising more than 30 percent year over year. TripAdvisor said its referral and transaction revenue was $154 million, flat from last year. The company’s other hotel revenue, which includes revenue from non-TripAdvisor branded websites, declined 20.7 percent in the quarter, falling to $29 million.

The strong dollar reduced TripAdvisor’s sales growth by two percentage points and reduced adjusted pre-tax operating earnings growth by a single percentage point. The percentage of sales coming from its North American market rose four percentage points to 57 percent. Europe remained flat at 29 percent, but both the Asia-Pacific and Latin America regions declined.

TripAdvisor hopes for double-digit percentage increases in revenue for 2017. CFO Ernst Teunissen said, “We turned a corner in the fourth quarter as growth rates improved, led by the U.S., [and] in 2017, we are prioritizing revenue growth as well as making the investments necessary to drive monetization, growth, and profitability on our platform.” The company authorized a $250 million stock buyback in January, representing roughly 3 percent of its outstanding shares at current prices. Shares of the company fell 5.1 percent to $49.99 in extended trading on Wednesday.
