Investing.com -- Shares in Hilton Inc (NYSE: HLT) slipped more than 2% in premarket trading Tuesday as the hotel operator reported second-quarter earnings roughly in line with expectations, while its third-quarter profit outlook missed analyst estimates.

Hilton posted second-quarter earnings per share of $2.29, just above the $2.26 analyst estimate. Revenue came in at $3.34 billion, roughly matching the $3.33 billion consensus. System-wide comparable Revenue Per Available Room (RevPAR) rose 3.9% on a currency-neutral basis compared with the same period a year earlier.

Adjusted EBITDA came in at $1.05 billion for the quarter.

The company approved 42,900 new rooms for development during the quarter, bringing its development pipeline to 541,300 rooms as of June 30, up 6% from a year earlier. Hilton added 24,100 rooms to its system, for net additions of 21,600 rooms in the quarter, contributing to net unit growth of 6.1% year-over-year.

"We delivered strong top and bottom-line results for the second quarter, driven by the continuation of strengthening demand trends and broad-based momentum across our system, which we expect to continue for the remainder of the year and into 2027," said CEO Christopher Nassetta.

For the third quarter, Hilton guided to diluted EPS, adjusted for special items, of $2.28 to $2.34, below the $2.43 consensus estimate. System-wide comparable RevPAR growth is expected to be approximately 4%, while adjusted EBITDA is projected to be $1.04 billion to $1.05 billion.

For the full year, Hilton now sees EPS of $8.89 to $9.01, versus a consensus of $9.01, with system-wide comparable RevPAR growth of 3.0% to 3.5% and adjusted EBITDA of $4.04 billion to $4.08 billion. The company said its outlook reflects expected third-quarter benefits from the World Cup and favorable calendar shifts, while the fourth quarter is expected to be weighed down by unfavorable calendar shifts and the midterm elections.

Hilton guided to full-year net unit growth of 6.0% to 7.0%, with stronger growth expected in the second half.
