Conference Call on Wednesday, November 10, 2021, at 8 p.m. ET with Accompanying Investor Presentation

Beijing, China, November 10, 2021 (NY)/ November 11, 2021 (China) — ATA Creativity Global (“ACG” or the “Company”, Nasdaq: AACG), an international educational services company focused on providing quality learning experiences that cultivate and enhance students’ creativity, today announced preliminary unaudited financial results for the quarter and nine months ended September 30, 2021 (“Third Quarter 2021” and “Nine Months 2021”, respectively).

Third Quarter 2021 and Nine Months 2021 Highlights

Management Commentary

Mr. Kevin Ma, Chairman and CEO of ACG, stated, “We are pleased to have achieved over 30% growth on the top line during Third Quarter 2021, driven primarily by increased contributions from our portfolio training and research-based learning services, supported by steady enrollments across our major service lines. We are pleased to see increasingly positive reception of and interest in our research-based learning programs and will continue to explore ways in which we can better support existing and potential students given the changing education landscape. During Third Quarter 2021, we continued to invest in the development of new offerings and our existing IT platform, which we believe will help drive future growth. We are committed to maintaining our leading position in creative arts education with a focus on positive outcomes for our students.”

Outlook

Mr. Jun Zhang, President of ACG, stated, “In recent months, there has been a great deal of uncertainty in the Chinese education industry. We have seen some companies close their doors due to their inability to operate through the challenges of the pandemic, and others are struggling and offering significant discounts to attract students. In addition, certain after-school tutoring institutions have been unable to continue to provide their academic course tutoring services for K-12 students as a result of the government’s recently announced Opinions on Further

Alleviating the Burden of Homework and After-School Tutoring for Students in Compulsory Education (the “Opinion”). While our portfolio training services and other art-related services are not considered academic tutoring for K-12 students and thus not subject to the Opinion, the Opinion appears to have affected certain consumers’ confidence in the overall education industry. In this environment, students and parents are hesitant to commit to paying for longer programs. In response to the foregoing, ACG has been exploring potential alternative offerings that may be better fit for students’ needs. With over 20 campus locations nationwide and a proven track record of our students going on to well-known art schools and institutions around the world, we remain confident in ACG’s ability to stand out from our competitors.”

ACG’s total net revenues for Third Quarter 2021 increased 31.0% to RMB55.3 million (US$8.6 million), from RMB42.2 million in the prior-year period, driven primarily by portfolio training and research-based learning services as a result of ACG’s continuous efforts in shifting students into project-based programs from time-based programs and developing various research-based learning programs to better meet market demand.

Currency Convenience Translation

The Company’s financial information is stated in Renminbi (“RMB”), the currency of the People’s Republic of China. The translations of RMB amounts for the quarter ended September 30, 2021, into U.S. dollars are included solely for the convenience of readers and have been made at the rate of RMB6.4434 to US$1.00, the noon buying rate as of September 30, 2021, in New York for cable transfers in RMB per U.S. dollar as set forth in the H.10 weekly statistical release of the Federal Reserve Board. Such translations should not be construed as representations that RMB amounts could be converted into U.S. dollars at that rate or any other rate, or to be the amounts that would have been reported under U.S. generally accepted accounting principles (“GAAP”).

About Non-GAAP Financial Measures

To supplement ACG’s consolidated financial information presented in accordance with U.S. GAAP, ACG uses the following non-GAAP financial measures: net loss excluding share-based compensation expense and foreign currency exchange gain or loss, and basic and diluted losses per common share and ADS excluding share-based compensation expense and foreign currency exchange gain or loss.

The presentation of these non-GAAP financial measures is not intended to be considered in isolation or as a substitute for the financial information prepared and presented in accordance with GAAP. ACG believes these non-GAAP financial measures provide meaningful supplemental information about its performance by excluding share- based compensation expense and foreign currency exchange gain or loss, which may not be indicative of its operating performance.

ACG believes that both management and investors benefit from these non-GAAP financial measures in assessing its performance and when planning and forecasting future periods. These non-GAAP financial measures also facilitate management’s internal comparisons to ACG’s historical performance. ACG computes its non-GAAP financial measures using a consistent method from period to period. ACG believes these non-GAAP financial measures are

5

useful to investors in allowing for greater transparency with respect to supplemental information used by management in its financial and operational decision making. A limitation of using non-GAAP net loss excluding share-based compensation expense and foreign currency exchange gain or loss and basic and diluted losses per common share and per ADS excluding share-based compensation expense and foreign currency exchange gain or loss is that share-based compensation charges and foreign currency exchange gain or loss have been, and are expected to continue to be for the foreseeable future, a significant recurring expense in ACG’s business.

Management compensates for these limitations by providing specific information regarding the GAAP amounts excluded from each non-GAAP measure. The table captioned “Reconciliations of Non-GAAP Measures to the Most Comparable GAAP Measures” shown at the end of this news release has more details on the reconciliations between GAAP financial measures that are most directly comparable to the non-GAAP financial measures used by ACG.
