US-based fast food restaurant chain Jack in the Box has reported 8.6% growth in systemwide sales for the fourth quarter of the fiscal year 2021, which ended on 3 October.

However, the company recorded systemwide sales growth of 0.2% when the 53rd week of the fiscal year is excluded for comparison to the previous year.

Company-operated same-store sales witnessed a decline of 4.4% in the quarter, while franchise-owned same-store sales grew by 0.6% in the same period.

During Q4 FY21, Jack in the Box’s store footprint recorded a net decrease of one store, due to four store openings and five closures.

The company’s fourth quarter diluted earnings per share jumped 9.8% to $1.80 on a year-on-year (YoY) basis.

The restaurant chain’s revenues totalled $278.5m in the quarter, up 9% compared to $255.4m recorded in the comparable period last year.

Net earnings increased from $37.8m in the fourth quarter of fiscal 2020 to $38.9m in the fourth quarter of fiscal 2021.

Jack in the Box CEO Darin Harris said: “I am very proud of the execution and determination shown by our outstanding franchisees and corporate team members, continuing to deliver for our guests during a challenging operating environment.

“We closed the year with strong comps on a two-year basis of +12.3% in Q4, leading us to another record-setting year of store-level profitability – a key element in driving results against our growth strategy in the near future.

“We continue to focus heavily on making significant progress on our strategic pillars, growth objectives, and unlocking substantial value for Jack shareholders.”

Jack in the Box is one of the largest hamburger chains in the US with more than 2,200 locations in 21 states and Guam.

In September, the restaurant chain selected ParTech’s customer loyalty and engagement platform Punchh to improve digital experiences for customers.
