Aurora Mobile Limited Announces First Quarter 2020

Unaudited Financial Results

SHENZHEN, CHINA, June 11, 2020 – Aurora Mobile Limited (“Aurora Mobile” or the “Company”) (NASDAQ:JG), a leading mobile developer service provider in China, today announced its unaudited financial results for the first quarter ended March 31, 2020.

First Quarter 2020 Financial Highlights

First Quarter 2020 Operational Highlights

Mr. Weidong Luo, Chairman and Chief Executive Officer of Aurora Mobile, commented, “The first quarter of 2020 has proven to be a challenging one for many companies, including us. Firstly, the quarter is typically a seasonally weaker one due to the Chinese New Year holiday. This year, the COVID-19 outbreak adversely impacted this seasonally slow period even further across China. Many businesses were temporarily shut down or delayed restarting their operations for many weeks as the pandemic unfolded. Despite the slower than expected period, we ramped back up to 100% capacity by the middle of March, in line with most of our customers who resumed normal operations in mid-to-late March.”

“During this period of temporary disruption, we took the initiative to further strengthen our core competencies. This included narrowing our focus on Developer Services, improving operational and technical efficiency, streamlining internal procedures and reinforcing our commitment to delivering exceptional customer service. With these initiatives now in place, we believe we will emerge from this pandemic stronger than ever and ideally positioned to better adapt to the current uncertainties that hang over the market.”

“Beginning from this quarter, the revenues from Advertisement SaaS and Light-Push services, which help developers grow and monetize their user base, will be separately classified as “Value-Added-Services” under Developer Services. No changes are made to other revenue classifications. Our strategic focus remains to drive the growth of Developer Services and SaaS products. Overtime, we expect the revenue and gross profit contributions from Targeted Marketing to be less and less significant.”

“Market adoption of our Value-Added Services, which launched in the fourth quarter of 2019, has exceeded our expectations. The average monthly revenue from Value-Added Services was approximately RMB2.1M in the first quarter of 2020. The revenue has since doubled in the month of April and we expect the strong revenue growth momentum to continue into the second quarter of 2020.”

Mr. Fei Chen, President of Aurora Mobile, added, “Our core businesses, including Developer Services and SaaS products, continued to see healthy 15% year-over-year revenue growth and 20% year-over-year gross profit growth despite the impact from the pandemic and low seasonality. Our strategic transition away from the low margin and high-risk Targeted Marketing business, that we started in the third quarter 2019, has gone very well with Targeted Marketing now only contributing about 12% of our total gross profit. Such transition has reflected in our revenue decline by 45% from RMB230 million in first quarter 2019 to RMB126 million in the current quarter. Our growth of revenue and profitability is no longer dependent upon this legacy Targeted Marketing business. ”

“Developer Services once again was the highlight of the quarter with an impressive performance where it recorded a solid 72% year-over-year increase in revenue on the back of strong growth in both Subscription businesses and Value-Added Services. The combined revenues from SaaS products, including financial risk management, market intelligence and iZone, decreased by 28% year-over-year from RMB24.8 million in the first quarter of last year to RMB17.8 million. The decline was due to the COVID-19 outbreak which impacted customer demand in financial risk management and location-based iZone business.”

Mr. Shan-Nen Bong, Chief Financial Officer of Aurora Mobile, added, “Despite the tough business environment in the first quarter of 2020, we managed to maintain our gross margins at 33%, flat sequentially and a meaningful increase from 27.6% during the same period last year.”

“As a percentage of revenue, Developer Services and SaaS-based products accounted for 39% during the quarter, a significant increase from 19% during the same period last year. Targeted Marketing, on the other hand, accounted for 61% of total revenue during the quarter, down from 81% during the same period last year. In terms of gross margin contribution, Developer Services and SaaS-based products accounted for 88% of gross profit whereas Targeted Marketing, which is no longer our strategic focus, accounted for only 12% during the quarter. With Developer Services and SaaS Products increasingly contributing more meaningfully to gross margins, we believe we have identified and built a higher quality, more resilient and sustainable business model that can support and fuel a further expansion of our margins and profitability in the future.”

First Quarter 2020 Financial Results

Revenues were RMB126.2 million (US$17.8 million), a decrease of 45% from RMB230.5 million in the same quarter of last year, mainly due to the decrease in revenues from Targeted Marketing and other SaaS products, which together decreased 55% year-over-year. This was partially offset by revenue growth from Developer Services which increased 72% year-over-year.

Cost of revenues was RMB84.9 million (US$12.0 million), a decrease of 49% from RMB167.2 million in the first quarter of 2019. The decrease was mainly due to a RMB82.6 million decrease in media costs and a RMB0.6 million decrease in staff cost which were partially offset by a RMB2.0 million increase in SMS costs.

Gross profit was RMB41.3 million (US$5.8 million), a decrease of 35% from RMB63.3 million in the first quarter of 2019, primarily due to the decrease in gross profit from Targeted Marketing business as the Company strategically shifts its focus to Developer Services and SaaS-based products.

Total operating expenses were RMB93.1 million (US$13.1 million), a decrease of 1% from RMB94.2 million in the same quarter of last year.

Loss from operations was RMB51.7 million (US$7.3 million), compared with RMB30.9 million in the same quarter of last year.

Net Loss was RMB51.0 million (US$7.2 million), compared with RMB23.7 million in the same quarter of last year.

Adjusted net loss (non-GAAP) was RMB43.2 million (US$6.1 million), compared with RMB16.7 million in the same period of last year.

Adjusted EBITDA (non-GAAP) was negative RMB30.3 million (US$4.3 million) compared with negative RMB7.4 million for the same period of last year.

The cash and cash equivalents, restricted cash and short -term investment decreased from RMB431.6 million as of December 31,2019 to RMB383.4 million (US$54.2 million) as of March 31, 2020.

Update on Share Repurchase

As of March 31, 2020, the Company had repurchased a total of 920,606 ADS. No ADS were repurchased during first quarter of 2020.

The Company today announced that its board of directors has extended its share repurchase program and also approved a new program under which the Company may repurchase up to US$10 million of its shares over the next twelve months. The Company’s proposed repurchases may be made from time to time on the open market at prevailing market prices, in privately negotiated transactions, in block trades and/or through other legally permissible means, depending on market conditions and in accordance with applicable rules and regulations. The Company’s board of directors will review the share repurchase program periodically, and may authorize adjustment of its terms and size. The Company plans to fund repurchases from its existing cash balance.

Use of Non-GAAP Financial Measures

In evaluating the business, the Company considers and uses two non-GAAP measures, adjusted net loss and adjusted EBITDA, as a supplemental measure to review and assess its operating performance. 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 U.S. GAAP. The Company defines adjusted net loss as net loss excluding share-based compensation, reduction in force charges, fair value loss/(gain) of long-term investment, and change in fair value of derivative liability. The Company defines adjusted EBITDA as net loss excluding interest expense, depreciation of property and equipment, amortization of intangible assets, income tax (expense) benefit, share-based compensation, reduction in force charges, fair value loss/(gain) of long-term investment, and change in fair value of derivative liability.

The Company believes that adjusted net loss and adjusted EBITDA help identify underlying trends in its business that could otherwise be distorted by the effect of certain expenses that it includes in loss from operations and net loss.

The Company believes that adjusted net loss and adjusted EBITDA provide useful information about its operating results, enhance the overall understanding of its past performance and future prospects and allow for greater visibility with respect to key metrics used by the management in their financial and operational decision-making.

The non-GAAP financial measures are not defined under U.S. GAAP and are not presented in accordance with U.S. GAAP. The non-GAAP financial measures have limitations as analytical tools. One of the key limitations of using adjusted net loss and adjusted EBITDA is that they do not reflect all items of income and expense that affect the Company’s operations. Further, the non-GAAP financial measures may differ from the non-GAAP information used by other companies, including peer companies, and therefore their comparability may be limited.

The Company compensates for these limitations by reconciling the non-GAAP financial measures to the nearest U.S. GAAP performance measure, all of which should be considered when evaluating the Company’s performance. The Company encourages you to review its financial information in its entirety and not rely on a single financial measure.

Reconciliations of the non-GAAP financial measures to the most comparable U.S. GAAP measure are included at the end of this press release.
