Financial and Operating Data——Third Quarter of Fiscal Year 2015

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

“We delivered strong top line growth in the third quarter as we continued to expand our tutoring services as planned. I am particularly pleased that we have maintained growth momentum even in the midst of the tremendously exciting changes which bring opportunities of building new education models for the future,” said TAL’s Chairman and Chief Executive Officer, Mr. Bangxin Zhang.

“In this quarter, we also took a minority equity interest in Guokr, a popular mobile and web-based community for science and technology education in China. We believe Guokr’s Massive Online Open Course (MOOC) content will enrich our blended learning approach across multi-media platforms. Its customer base of high school, college students and young graduates is also highly complementary to our strong K-12 user base. Through in-house development and strategic investments, we are bringing together the technology, community and education resources to become a leading technology-focused education services provider in China,” Mr. Zhang added.

Rong Luo, Chief Financial Officer, said, “The healthy geographical spread of our tutoring services is more evident than ever as cities other than Beijing and Shanghai contributed over half of our core small class revenues in the third quarter. We continued to invest prudently in meeting the growing demand for our services by adding 15 learning centers to reach a total of 289 learning centers and adding 533 small class classrooms during the first nine months of fiscal year 2015. We will continue to execute our plan to add more learning center capacity in those cities with satisfactory utilization rates, such as Guangzhou, to meet the growing demand for our class-based tutoring services. “

Financial Results for the Third Quarter of Fiscal Year 2015

Net Revenues

In the third quarter of fiscal year 2015, TAL reported net revenues of US$99.4 million, representing a 35.1% increase from US$73.5 million in the third quarter of fiscal year 2014. The increase was mainly driven by an increase in total student enrollments. Total student enrollments increased by 35.6% to approximately 304,910 from approximately 224,810 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. In the third quarter of fiscal year 2015, average selling price (ASP) was US$326, which remained almost unchanged from the same quarter of fiscal year 2014. ASP was stable mainly because the increases in the hourly rate of the small class course offerings were offset by more enrollment contribution from online courses and the foreign exchange rate fluctuation.

Operating Costs and Expenses

In the third quarter of fiscal year 2015, operating costs and expenses were US$91.2 million, a 46.0% increase from US$62.5 million in the third quarter of fiscal year 2014. Non-GAAP operating costs and expenses, which excluded share-based compensation expenses, were US$86.3 million, a 42.9% increase from US$60.4 million in the third quarter of fiscal year 2014.

Cost of revenues increased by 36.5% to US$49.0 million, from US$35.9 million in the third quarter of fiscal year 2014. 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 36.5% to US$48.9 million, from US$35.9 million in the third quarter of fiscal year 2014.

Selling and marketing expenses increased by 45.7% to US$13.6 million, from US$9.3 million in the third quarter of fiscal year 2014. Non-GAAP selling and marketing expenses, which excluded share-based compensation expenses, increased by 44.8% to US$13.1 million, from US$9.0 million in the third quarter of fiscal year 2014. The increase of selling and marketing expenses in the third quarter of fiscal year 2015 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 65.8% to US$28.7 million, from US$17.3 million in the third quarter of fiscal year 2014. 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, and 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 56.4% to US$24.3 million, from US$15.5 million in the third quarter of fiscal year 2014.

Total share-based compensation expenses allocated to the related operating costs and expenses increased by 137.3% to US$4.9 million in the third quarter of fiscal year 2015, from US$2.1 million in the same period of fiscal year 2014. The increase of share-based compensation expenses was mainly driven by new grants of nonvested shares to directors and employees by the company in the first nine months of fiscal year 2015.

Gross Profit

Gross profit increased by 33.8% to US$50.4 million, from US$37.7 million in the third quarter of fiscal year 2014.

Income from Operations

Income from operations decreased by 30.9% to US$8.2 million, from US$11.9 million in the third quarter of fiscal year 2014. Non-GAAP income from operations, which excluded share-based compensation expenses, decreased by 6.0% to US$13.1 million, from US$14.0 million in the third quarter of fiscal year 2014.

Other Expense

Other expense was US$0.3 million for the third quarter of fiscal year 2015, compared to other expense of US$51.1 thousand in the third quarter of fiscal year 2014.

Gain on Fair Value Change of Long-term Investment

Gain on fair value change of long-term investment was US$1.0 million for the third quarter of fiscal year 2015, compared to nil in the third quarter of fiscal year 2014. The change was primarily attributable to changes in fair value of our minority equity investment in China.

Income Tax Expense

Income tax expense was US$0.4 million in the third quarter of fiscal year 2015, as compared to US$1.9 million in the third quarter of fiscal year 2014. The decrease was mainly because TAL Beijing has qualified as a “high and new technology enterprise strongly supported by the state” in the third quarter of fiscal year 2015, and is therefore entitled to a preferential tax rate of 15% from calendar year 2014 through 2016. We have trued up the first and second quarter income tax expense impact in the third quarter.

Net Income Attributable to TAL Education Group

Net income attributable to TAL decreased by 12.4% to US$11.0 million, from US$12.5 million in the third quarter of fiscal year 2014. Non-GAAP net income attributable to TAL, which excluded share-based compensation expenses, increased by 8.8% to US$15.9 million, from US$14.6 million in the third quarter of fiscal year 2014.

Basic and Diluted Net Income per ADS

Basic and diluted net income per ADS were US$0.14 and US$0.13, respectively, in the third quarter of fiscal year 2015. Non-GAAP basic and Non-GAAP diluted net income per ADS, which excluded share-based compensation expenses, were US$0.20 and US$0.19, respectively.

Capital Expenditures

Capital expenditures for the third quarter of fiscal year 2015 were US$7.5 million, representing an increase of US$4.2 million from US$3.3 million in the third quarter of fiscal year 2014. The increase was mainly due to leasehold improvements, mobile network research and development, and the purchase of servers, computers, software systems and other hardware for the Company’s teaching facilities.

Cash, Cash Equivalents, and Term Deposits

As of November 30, 2014, the Company had US$526.4 million of cash and cash equivalents and US$40.8 million of term deposits, as compared to US$269.9 million of cash and cash equivalents and nil of term deposits as of February 28, 2014.

Deferred Revenue

As of November 30, 2014, the Company’s deferred revenue balance was US$247.0 million, as compared to US$173.0 million as of November 30, 2013, representing an increase of 42.8%.

Financial Results for the First Nine Months of Fiscal Year 2015

Net Revenues

For the first nine months of fiscal year 2015, TAL reported net revenues of US$310.8 million, representing a 37.0% increase from US$226.9 million in the first nine months of fiscal year 2014. The increase was mainly driven by increases of enrollments in the small class offerings. Total student enrollments increased by 36.7% to approximately 992,080 from approximately 725,950 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. In the first nine months of fiscal year 2015, average selling price (ASP) was US$313, which remained unchanged from the same period of fiscal year 2014. ASP was unchanged year-over-year mainly because the increases in the hourly rate of the small class course offerings were offset by more enrollment contribution from online courses and the foreign exchange rate fluctuation.

Operating Costs and Expenses

In the first nine months of fiscal year 2015, operating costs and expenses were US$258.6 million, a 39.9% increase from US$184.8 million in the first nine months of fiscal year 2014. Non-GAAP operating costs and expenses, which excluded share-based compensation expenses, were US$245.4 million, a 37.1% increase from US$179.0 million in the first nine months of fiscal year 2014.

Cost of revenues increased by 29.9% to US$143.9 million, from US$110.8 million in the first nine months of fiscal year 2014. 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 29.9% to US$143.9 million, from US$110.7 million in the first nine months of fiscal year 2014.

Selling and marketing expenses increased by 48.9% to US$38.1 million, from US$25.6 million in the first nine months of fiscal year 2014. Non-GAAP selling and marketing expenses, which excluded share-based compensation expenses, increased by 47.9% to US$36.5 million, from US$24.7 million in the first nine months of fiscal year 2014. The increase of selling and marketing expenses in the first nine months of fiscal year 2015 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 58.1% to US$76.6 million, from US$48.5 million in the first nine months of fiscal year 2014. 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, and 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 49.2% to US$65.1 million, from US$43.6 million in the first nine months of fiscal year 2014.

Total share-based compensation expenses allocated to the related operating costs and expenses increased by 127.8% to US$13.1 million in the first nine months of fiscal year 2015, from US$5.8 million in the same period of fiscal year 2014. The increase of share-based compensation expenses was mainly driven by new grants of nonvested shares to directors and employees by the company in the first nine months of fiscal year 2015.

Gross profit increased by 43.7% to US$166.9 million, from US$116.1 million in the first nine months of fiscal year 2014.

Other Income

Other income was US$0.8 million for the first nine months of fiscal year 2015, compared to other income of US$0.5 million in the first nine months of fiscal year 2014. Other income in the first nine months was mainly driven by 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$8.2 million in the first nine months of fiscal year 2015, as compared to US$6.6 million in the first nine months of fiscal year 2014. The increase was mainly due to the growth of income before income tax.

Business Outlook

In the fourth quarter we again deal with the usual every other year seasonality associated with the timing of Chinese New Year. The late start of spring term, which typically begins after Chinese New Year, will cause one less weekend of classes to be recorded in February as compared to last year. Taking into consideration this seasonality impact and the revenue shift from the third quarter to the fourth quarter because of the late fall term and the delay of classes due to APEC Forum in Beijing, total net revenues for the fourth quarter of fiscal year 2015 are expected to be between US$116.6 million and US$119.2 million, representing an increase of 34% to 37% on a year-over-year basis. This estimation also incorporates the quarter-to-date exchange rate impact, which is negative 2.0% as of today, assuming no more material change in exchange rates.

Total net revenues for the fiscal year ending February 28, 2015 are expected to be between US$427.4 million and US$430.0 million, representing an increase of 36% to 37% year-over-year.

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

We also operate www.jzb.com, a leading online education platform in China. Our ADSs trade on the New York Stock Exchange under the symbol “XRS.”

About Non-GAAP Financial Measures

In evaluating its business, TAL considers and uses the following measures defined as non-GAAP financial measures by the U.S. Securities and Exchange Commission 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 from 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.
