Financial and Operating Data—First Quarter of Fiscal Year 2016

(In US$ thousands, except per ADS data, student enrollments and percentages)

“First quarter revenue exceeded our expectation due to very strong growth in cities other than Beijing. We also achieved over 40% year-on-year growth in both operating income and net income growth even though we opened 14 new learning centers on a net basis in the first quarter. We expect this strong business momentum to continue in the second quarter,” said TAL’s Chairman and Chief Executive Officer, Mr. Bangxin Zhang.

“When we look at the revenue contribution from small class in the cities we generate most revenue from, we see how our revenue base is becoming more broadly spread over a larger number of cities, reflecting the rapid and healthy development of our core small class business. In the first quarter, the top five cities in terms of revenue contribution accounted for an aggregate of 72% of small class revenues. In the same period last year, the top 5 cities contributed 80%,” Mr. Zhang added. “This robust start in our business and operations for Fiscal Year 2016 supports our ongoing plans to gain long-term leverage in the future education business models. From our company’s early beginnings we have firmly believed that innovation and change in education is part and parcel of our business, and we want to be right at the cusp of where education meets technology.”

Mr. Rong Luo, Chief Financial Officer, said, “We achieved a very solid quarter on all financial metrics, with a top line performance that is mostly enrollment driven. We saw strong enrollment growth in small class in the first quarter as well as a record high number of online student enrollments, which for the first time reached 20% of all enrollments.”

Financial Results for the First Quarter of Fiscal Year 2016

Net Revenues

In the first quarter of fiscal year 2016, TAL reported net revenues of US$129.4 million, representing a 45.3% increase from US$89.0 million in the first quarter of fiscal year 2015. The increase was mainly driven by an increase in total student enrollments, which increased by 47.6% to approximately 412,120 from approximately 279,200 in the same period of the prior year. The increase in total student enrollments was driven primarily by increases of enrollments in the small class offerings and online courses. The increase in net revenues was partially offset by a decrease in our average selling price (ASP), which decreased by 1.5% to US$314 in the first quarter of fiscal year 2016 from US$319 in the first quarter of fiscal year 2015. The decrease in ASP was mainly because the increases in the hourly rate of the small class course offerings were offset by more enrollment contribution from online courses.

Operating Costs and Expenses

In the first quarter of fiscal year 2016, operating costs and expenses were US$109.8 million, a 45.5% increase from US$75.5 million in the first quarter of fiscal year 2015. Non-GAAP operating costs and expenses, which excluded share-based compensation expenses, were US$104.7 million, a 46.6% increase from US$71.4 million in the first quarter of fiscal year 2015.

Cost of revenues increased by 46.2% to US$61.0 million from US$41.7 million in the first quarter of fiscal year 2015. The increase in cost of revenues was mainly due to an increase in teacher compensation, rental costs and other staff costs associated primarily with an expansion of learning center capacity, as well as increases in wages and teacher fees. Non-GAAP cost of revenues, which excluded share-based compensation expenses, increased by 46.2% to US$61.0 million, from US$41.7 million in the first quarter of fiscal year 2015.

Selling and marketing expenses increased by 34.1% to US$15.3 million from US$11.4 million in the first quarter of fiscal year 2015. Non-GAAP selling and marketing expenses, which excluded share-based compensation expenses, increased by 35.5% to US$14.8 million, from US$10.9 million in the first quarter of fiscal year 2015. The increase of selling and marketing expenses in the first quarter of fiscal year 2016 was primarily a result of an increase in compensation to sales and marketing staff to support a greater number of programs and service offerings versus the year-ago period.

General and administrative expenses increased by 49.8% to US$33.6 million from US$22.4 million in the first quarter of fiscal year 2015. The increase in general and administrative expenses was mainly due to an increase in the number of our general and administrative personnel compared to the year-ago period and an increase in compensation to our general and administrative personnel, in particular such personnel supporting our online education initiatives among other new programs and service offerings. Non-GAAP general and administrative expenses, which excluded share-based compensation expenses, increased by 53.8% to US$29.0 million, from US$18.9 million in the first quarter of fiscal year 2015.

Total share-based compensation expenses allocated to the related operating costs and expenses increased by 25.4% to US$5.1 million in the first quarter of fiscal year 2016 from US$4.0 million in the same period of fiscal year 2015.

Gross Profit

Gross profit increased by 44.5% to US$68.4 million from US$47.3 million in the first quarter of fiscal year 2015.

Income from Operations

Income from operations increased by 43.4% to US$19.6 million from US$13.7 million in the first quarter of fiscal year 2015. Non-GAAP income from operations, which excluded share-based compensation expenses, increased by 39.3% to US$24.7 million from US$17.7 million in the first quarter of fiscal year 2015.

Other Income / (Expense)

Other income was US$1.4 million for the first quarter of fiscal year 2016, compared to other expense of US$0.3 million in the first quarter of fiscal year 2015. Other income for the first quarter of fiscal year 2016 was mainly due to exchange gains. As the Company holds a significant portion of cash balance in RMB and reports in US Dollars, it benefits from exchange gains in times of relative strength of the RMB and incurs exchange losses in times of relative strength of the U.S. Dollar.

Income Tax Expense

Income tax expense was US$4.8 million in the first quarter of fiscal year 2016, compared to US$2.4 million in the first quarter of fiscal year 2015. The increase was mainly due to the increase in income before tax and effective income tax rate. The effective income tax rate increased mainly because one of TAL’s subsidiaries was entitled to a two-year exemption from enterprise income tax for calendar years 2013 and 2014 as a Newly Established Software Enterprise, and enjoys preferential tax rate of 12.5% for calendar years 2015 through 2017.

Net Income Attributable to TAL Education Group

Net income attributable to TAL increased by 42.0% to US$19.0 million from US$13.4 million in the first quarter of fiscal year 2015. Non-GAAP net income attributable to TAL, which excluded share-based compensation expenses, increased by 38.1% to US$24.0 million, from US$17.4 million in the first quarter of fiscal year 2015.

Basic and Diluted Net Income per ADS

Basic and diluted net income per ADS were US$0.24 and US$0.23, respectively, in the first quarter of fiscal year 2016. Non-GAAP basic and Non-GAAP diluted net income per ADS, which excluded share-based compensation expenses, were US$0.30 and US$0.28, respectively.

Capital Expenditures

Capital expenditures for the first quarter of fiscal year 2016 were US$6.3 million, an increase of US$1.9 million from US$4.4 million in the first quarter of fiscal year 2015. The increase was mainly due to leasehold improvements and the purchase of servers, computers, software systems and other hardware for the Company’s teaching and mobile network research and development facilities.

Cash, Cash Equivalents, and Term Deposits

As of May 31, 2015, the Company had US$582.2 million of cash and cash equivalents and US$49.3 million of term deposits, compared to US$470.2 million of cash and cash equivalents and US$21.2 million of term deposits as of February 28, 2015.

Deferred Revenue

As of May 31, 2015, the Company’s deferred revenue balance was US$331.3 million, compared to US$235.8 million as of May 31, 2014, representing a year-over-year increase of 40.5%, which was mainly contributed by the tuition revenue collected in advance for the Xueersi Peiyou small class summer and fall semesters.

Business Outlook

Based on the Company’s current estimates, total net revenues for the second quarter of fiscal year 2016 are expected to be between US$161.5 million and US$165.2 million, representing an increase of 32% to 35% on a year-over-year basis, assuming no material change in exchange rates.

These estimates reflect the Company’s current expectation, which is subject to change.

About Non-GAAP Financial Measures

In evaluating its business, TAL considers and uses the following measures defined as non-GAAP financial measures by the SEC as supplemental metrics to review and assess its operating performance: non-GAAP operating costs and expenses, non-GAAP cost of revenues, non-GAAP selling and marketing expenses, non-GAAP general and administrative expenses, non-GAAP income from operations, non-GAAP net income attributable to TAL, non-GAAP basic and non-GAAP diluted net income per ADS. To present each of these non-GAAP measures, the Company excludes share-based compensation expenses. 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. For more information on these non-GAAP financial measures, please see the table captioned “Reconciliations of non-GAAP measures to the most comparable GAAP measures” set forth at the end of this release.

TAL believes that these non-GAAP financial measures provide meaningful supplemental information regarding its performance and liquidity by excluding share-based expenses that may not be indicative of its operating performance from a cash perspective. TAL 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 TAL’s historical performance and liquidity. TAL computes its non-GAAP financial measures using the same consistent method from quarter to quarter and from period to period.TAL 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 measures is that these non-GAAP measures exclude share-based compensation charges that have been and will continue to be for the foreseeable future a significant recurring expense in the Company’s business. Management compensates for these limitations by providing specific information regarding the GAAP amounts excluded from each non-GAAP measure. The accompanying tables have more details on the reconciliations between GAAP financial measures that are most directly comparable to non-GAAP financial measures.
