Beijing, China, November 14, 2019 (NY) / November 15, 2019 (China) — ATA Creativity Global (“ACG” or the “Company”, Nasdaq: AACG), a company focused on providing students with quality educational experiences and services in China and abroad, today announced preliminary unaudited financial results for the three months ended September 30, 2019.

2019 Third Quarter and Subsequent Operating Highlights and Certain Events

Management Commentary

Mr. Kevin Ma, Chairman and CEO, stated, “We are pleased that Huanqiuyimeng is now a wholly owned subsidiary of ATA Creativity Global, our Company’s new name that reflects the direction in which we are heading. Our third quarter 2019 results incorporate about two months of operating and financial results from Huanqiuyimeng. The acquisition of Huanqiuyimeng marks the first major step forward in our long-term strategy of becoming a leading international education service provider with a special focus on the rapidly expanding art and creativity education market. Huanqiuyimeng has earned its reputation for excellence in this particular area, and we look forward to serving more students all over China who are passionate about pursuing a future in art and other creative fields.”

Outlook

Mr. Jun Zhang, President of ACG, stated, “In the fourth quarter of 2019, we are focused on integrating Huanqiuyimeng operations and personnel into the listed company (i.e., ACG) with a goal of accelerating enrollment in 2020. We continue working closely with Huanqiuyimeng management on prioritizing growth initiatives and look forward to using our resources to help Huanqiuyimeng efficiently scale its operations through geographic expansion, new product offerings, and new partnerships. We are well positioned to take advantage of the growing demand from Chinese students and young professionals focused on art and creative fields, as well as overseas educational experiences.”

Operating Review

Enrollment Update

Please note that the following information reflects enrollment information for the Partial Third Quarter Period beginning from August 6, 2019, to September 30, 2019, as control of Huanqiuyimeng transitioned to ACG on August 6, 2019.

Huanqiuyimeng student enrollment for the Partial Third Quarter Period was 838, of which 550 were enrolled in the portfolio training program, Huanqiuyimeng’s main line of business that primarily consists of one-on-one training for students focused in arts and creative studies (the “Portfolio Training Program”). The Portfolio Training Program consists of time-based programs, for which revenue is recognized per credit hour delivered, and project-based programs, for which projects are carried out through the delivery of credit hours but revenue is recognized per project milestone completed within the contract term. Students who elect the time-based program enroll in a certain number of consulting/training hours over the contract term, whereas students who elect the project-based program have no consulting/training hour constraint over the contract term but will be guided through a certain number of projects needed to complete a portfolio, which will be predetermined and agreed upon the signing of a contract. Under project-based programs, the number of credit hours required to complete a project may vary depending on the background and requirements of the students.

During the Partial Third Quarter, 288 students were enrolled in Huanqiuyimeng’s other programs, which mainly consist of educational travel and language preparation programs.

A total of 34,988 credit hours were delivered during the Partial Third Quarter Period, of which 22,708 credit hours were delivered for time-based programs and 12,280 credit hours were delivered for project-based programs.

The following is a summary of the credit hours delivered for the Portfolio Training Program, for the period beginning August 6, 2019, to September 30, 2019, compared to those for the prior-year period:

Certain line items in the condensed consolidated statements of comprehensive income (loss) for the three months and nine months ended September 30, 2018, in this press release have been revised as a result of adjustments made in the Company’s annual report for the fiscal year ended December 31, 2018.

pursuant to the accounting treatment of discontinued operations, under which the Company accounted for the sale of business of ATA Online (Beijing) Education Technology Co., Ltd, or ATA Online, a former subsidiary of the Company. The income from discontinued operations, net of income taxes, recorded in the three months ended September 30, 2019, was to account for the contingencies that arose pursuant to terms in the sale of business of ATA Online.

GAAP Results

ACG’s total net revenues for the third quarter of 2019 were RMB42.4 million (US$5.9 million), compared to RMB1.0 million in the prior-year period, driven primarily by revenue contributions from the recently completed acquisition of Huanqiuyimeng. Revenues from the portfolio training segment were RMB29.3 million, or 69.0% of total net revenues, during the period. Revenues from the other education services segment and K-12 business were RMB13.1 million, or 31.0% of total net revenues.

Gross profit for the third quarter of 2019 was RMB16.6 million (US$2.3 million), compared to gross loss of RMB0.5 million in the prior-year period. Gross margin was 39.1% during the period, compared to negative gross margin of 46.0% in the prior-year period, prior to the acquisition of Huanqiuyimeng.

Total operating expenses for the third quarter of 2019 were RMB41.0 million (US$5.7 million), compared to RMB11.4 million in the prior-year period, primarily due to increased selling, general and administrative (SG&A) expenses of RMB26.8 million related to the newly acquired Huanqiuyimeng operations. The Company also incurred increased operating expense, which primarily consisted of professional and consulting fees of RMB1.5 million related to the acquisition of Huanqiuyimeng as well as higher share-based compensation expense of RMB1.8 million related to new options granted during the period.

Loss from continuing operations for the third quarter of 2019 was RMB24.3 million (US$3.4 million), compared to RMB10.9 million in the prior-year period as a result of the increased operating expenses mentioned above.

Net loss from continuing operations attributable to ACG for the third quarter of 2019 was RMB24.4 million (US$3.4 million), compared to RMB8.9 million in the prior-year period.

For the three months ended September 30, 2019, basic and diluted losses from continuing operations per common share attributable to ACG were both RMB0.49 (US$0.07), compared to RMB0.52 for the prior-year period. Basic and diluted losses from continuing operations per ADS attributable to ACG were both RMB0.98 (US$0.14), compared to RMB1.04 in the prior-year period.

Non-GAAP Measures

Adjusted net loss attributable to ACG for the third quarter of 2019, which excludes share-based compensation expense and foreign currency exchange gain (non-GAAP), was RMB22.5 million (US$3.1 million), compared to adjusted net income of RMB1.0 billion in the prior-year period.

Basic and diluted losses per common share attributable to ACG excluding share-based compensation expense and foreign currency exchange gain (non-GAAP) for the third quarter of 2019, were both RMB0.46 (US$0.06). Basic and diluted losses per ADS attributable to ACG excluding share-based compensation expense and foreign currency exchange gain (non-GAAP) for the third quarter of 2019 were both RMB0.92 (US$0.12), compared to basic and diluted earnings per ADS attributable to ACG (non-GAAP) of RMB44.00 in the prior-year period.

Please see the note about non-GAAP measures and the reconciliation table at the end of this press release.

Other Data

The number of weighted average ADSs used to calculate both basic and diluted earnings per ADS for the third quarter ended September 30, 2019, was 26.4 million. Each ADS represents two common shares.

Balance Sheet Highlights

As of September 30, 2019, ACG’s cash and cash equivalents were RMB105.1 million (US$14.7 million), working capital deficit was RMB141.0 million (US$19.7 million), and total shareholders’ equity was RMB309.9 million (US$43.4 million); compared to RMB190.6 million, working capital of RMB193.6 million, and RMB276.2 million, respectively, as of December 31, 2018.

The factors that could cause the Company’s actual financial and operating results to differ from what the Company currently anticipates may include its ability to leverage its existing competency-focused assessment and education service capabilities, its ability to integrate the acquired business, its ability to identify and execute on M&A opportunities within the education sector, the economy of China, uncertainties with respect to China’s legal and

regulatory environments, and other factors stated in the Company’s filings with the U.S. Securities and Exchange Commission (“SEC”).

The financial information contained in this release should be read in conjunction with the consolidated financial statements and related notes included in the Company’s annual report on Form 20-F for its fiscal year ended December 31, 2018, and other filings that ACG has made with the SEC. The filings are available on the SEC’s website at www.sec.gov and at ACG’s website at www.atai.net.cn.

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, 2019, into U.S. dollars are included solely for the convenience of readers and have been made at the rate of RMB7.1477 to US$1.00, the noon buying rate as of September 30, 2019, 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 income (loss) excluding share-based compensation expense and foreign currency exchange gain or loss, and basic and diluted earnings (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 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 income (loss) excluding share-based compensation expense and foreign currency exchange gain or loss and basic and diluted earnings (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.
