The ONE Group Announces Preliminary Fourth Quarter and Full Year 2019 Sales Results

The ONE Group Hospitality, Inc. ("The ONE Group" or the "Company") (Nasdaq: STKS) today announced preliminary sales for the fourth quarter and full year ended December 31, 2019. The Company also announced its participation at the 22^nd Annual ICR Conference next week.

Preliminary sales highlights for the fourth quarter ended December 31, 2019 are as follows:

• Total GAAP revenues are expected to be approximately $52 million, an approximate increase of 102% from $25.8 million for the same quarter last year;
• Comparable sales* at owned and managed STK Restaurants rose 8.9% from the same quarter last year; and
• Sales for Kona Grill were $24.0 million for the quarter, stronger than initially expected for the period. Comparable sales at Kona Grill restaurants rose 3.9% from the same quarter last year.

Preliminary sales highlights for the full year ended December 31, 2019 are as follows:

• Total GAAP revenues are expected to be approximately $120.5 million, an approximate 41% increase from $85.6 million for 2018. On November 7, 2019, the Company had reiterated previous guidance of total GAAP revenues between $118 million and $120 million;
• Comparable sales* at owned and managed STK restaurants rose 8.3%, compared to 2018. On November 7, 2019 the Company had guided to domestic comparable store sales growth of about 6% to 8%; these results exceeded the high end of the comparable sales range guidance because of the strength of the holiday and events business; and
• U.S. STK brand restaurant sales rose approximately 15% to a record $115 million.

Comparable sales or same store sales ("SSS") represents total U.S. food and beverage sales at owned and managed units opened for at least a full 18-month period. This metric includes total revenue from our owned and managed locations. Revenues from locations where we do not directly control the event sales force (The W Hotel Westwood, CA) are excluded from this metric.

Emanuel "Manny" Hilario, President and CEO of The ONE Group, stated, "We are thrilled to have finished 2019 from a position of strength as we lapped an incredibly robust 15% comparison and still delivered same store sales growth of 8.9%, or nearly 24% on a two-year stacked basis, with all STK comp venues generating positive results. This performance is substantially better than the high end of the implied guided range for the period. We attribute our success to the great VIBE dining experiences we offer for events and group dining which have made our restaurants the holiday destination for so many while also enabling us to expand our share within the upscale segment."

Mr. Hilario continued, "Our newest locations, the Kona Grill restaurants, also provided great holiday offerings in each of their markets. We have embedded elements of STK's bar-business knowledge and VIBE dining into Kona Grill and are pleased with its performance in our first quarter of ownership. We attribute the brand's traction to its sales-driven culture and effective execution at all levels and are very confident in our ability to create long-term shareholder value through this accretive acquisition."

Mr. Hilario concluded, "Our recently opened STK San Juan, Puerto Rico is exceeding our expectations with a strong opening quarter and great holiday celebrations. For 2020, we project six to eight openings including five to six STK restaurants and one to two food and beverage venues. The STK Scottsdale location is opening during the first quarter of 2020."

Mr. Hilario and Mr. Tyler Loy, Chief Financial Officer, will present at the 22nd Annual ICR Conference at the Grand Lakes Hotel and Resort in Orlando, FL at 11:00 am Eastern Time on Tuesday, January 14, 2020.
