Non-GAAP Financial Measures

17EdTech’s management uses adjusted net loss as a non-GAAP financial measure to gain an understanding of 17EdTech’s comparative operating performance and future prospects.

Adjusted net loss represents net loss excluding share-based compensation expenses and such adjustment has no impact on income tax.

Adjusted net loss is used by 17EdTech’s management in their financial and operating decision-making as a non-GAAP financial measure; because management believes it reflects 17EdTech’s ongoing business and operating performance in a manner that allows meaningful period-to-period comparisons. 17EdTech’s management believes that such non-GAAP measure provides useful information to investors and others in understanding and evaluating 17EdTech’s operating performance in the same manner as management does, if they so choose. Specifically, 17EdTech believes the non-GAAP measure provides useful information to both management and investors by excluding certain charges that the Company believes are not indicative of its core operating results.

The non-GAAP financial measure has limitations. It does not include all items of income and expense that affect 17EdTech’s income from operations. Specifically, the non-GAAP financial measure is not prepared in accordance with GAAP, may not be comparable to non-GAAP financial measures used by other companies and, with respect to the non-GAAP financial measure that excludes certain items under GAAP, does not reflect any benefit that such items may confer to 17EdTech. Management compensates for these limitations by also considering 17EdTech’s financial results as determined in accordance with GAAP. The presentation of this additional information is not meant to be considered superior to, in isolation from or as a substitute for results prepared in accordance with US GAAP.

Exchange Rate Information

The Company’s business is primarily conducted in China and all of the revenues are denominated in Renminbi (“RMB”). However, periodic reports made to shareholders will include current period amounts translated into U.S. dollars (“USD” or “US$”) using the exchange rate as of balance sheet date, for the convenience of the readers. Translations of balances in the consolidated balance sheets and the related consolidated statements of operations, comprehensive loss, change in shareholders’ deficit and cash flows from RMB into USD as of and for the three months ended March 31, 2026 are solely for the convenience of the readers and were calculated at the rate of US$1.00=RMB6.8980 representing the noon buying rate set forth in the H.10 statistical release of the U.S. Federal Reserve Board on March 31, 2026. No representation is made that the RMB amounts could have been, or could be, converted, realized or settled into US$ at that rate on March 31, 2026, or at any other rate.
