Domino’s Pizza on Tuesday reported quarterly earnings and revenue that fell short of analysts’ expectations.

The pizza chain also announced that CEO Ritch Allison plans to retire. Domino’s Chief Operating Officer and U.S. President Russell Weiner will succeed him as head of the company, effective May 1.

Shares of the company fell roughly 8% in premarket trading.

Here’s what the company reported compared with what Wall Street was expecting, based on a survey of analysts by Refinitiv:

• Earnings per share: $4.25 vs. $4.28 expected
• Revenue: $1.34 billion vs. $1.38 billion expected

The pizza chain reported fourth-quarter net income of $155.7 million, or $4.25 per share, up from $151.9 million, or $3.85 per share, a year earlier. Analysts surveyed by Refinitiv were expecting earnings per share of $4.28.

Net sales dropped 1% to $1.34 billion, missing expectations of $1.38 billion.

U.S. same-store sales rose just 1% in the quarter, dragged down by weak performance by Domino’s company-owned restaurants. Analysts were expecting U.S. same-store sales growth of 2.9%, according to StreetAccount estimates.

Outside the U.S., the chain’s performance also disappointed. International same-store sales rose 1.8% in the quarter, falling short of StreetAccount estimates of 6.6%.

After he steps down as CEO, Allison will continue to serve as an advisor until July 15, when he officially retires.

The company also announced that it has tapped Sandeep Reddy as its next chief financial officer, effective April 1. Reddy is currently serving as CFO of Six Flags, although he announced on Monday that he will resign March 27. Prior to Six Flags, he served in the same role for Guess.

Correction: Domino’s net sales dropped 1% in the fourth quarter of 2021. A previous version misstated the year over year change.
