Investing.com -- Restaurant Brands International reported first-quarter earnings per share of $0.86, topping analyst estimates of $0.83. Revenue came in at $2.26 billion, against a consensus estimate of $2.24 billion.

Shares fell nearly 5% in premarket trading Wednesday despite the beat.

Consolidated system-wide sales grew 6.2% year-over-year, including 11.1% growth internationally. Comparable sales accelerated to 3.2%, with Burger King U.S. and international markets each posting growth of roughly 5.7% to 5.8%.

Adjusted operating income rose to $610 million from $539 million in the year-ago quarter, while adjusted EBITDA climbed to $706 million from $539 million.

"We delivered a strong start to the year, converting solid topline results into double-digit earnings growth while returning capital to shareholders through the resumption of share repurchases and our growing dividend," said Josh Kobza, CEO of RBI. "Tim Hortons and International each delivered their 20th consecutive quarter of positive comparable sales."

For 2026, the company guided segment general and administrative expenses of $600 million to $620 million, adjusted interest expense of $500 million to $520 million, and total capital expenditures and cash inducements of around $400 million.

Over the longer term, Restaurant Brands reiterated its targets of 3% or more in comparable sales growth and 8% or more in organic adjusted operating income growth on average through 2028.
