Rosetta Stone Inc. Reports First Quarter 2020 Results

Literacy Revenues Increase 18%, Consumer Bookings and Revenue Grow 42% and 5%, respectively, over Q1 2019

ARLINGTON, VA —May 6, 2020 — Rosetta Stone Inc. (NYSE:RST), a world leader in technology-based learning solutions, today announced financial results for the first quarter ended March 31, 2020.

First Quarter 2020 Highlights

“I am incredibly proud and thankful for the Rosetta Stone team. We had a good start to the year, with our Literacy and Consumer Language segments demonstrating particular strength. The team remained focused and delivered a terrific Q1, even while transitioning to an entirely remote work environment, highlighted by year-over-year consolidated bookings growth of 20%, and incredibly meaningful new initiatives to support customers in this time of great uncertainty and pain for many” said John Hass, Chairman and Chief Executive Officer.  “Programs like unlimited site licenses for all existing K-12 literacy and language customers for the rest of the school year and a free 3-month student license through our Consumer Language business to support families whose children were now learning from home are examples of our “customer first” approach.”

Mr. Hass continued, “Ultimately, when the pandemic is under control and life returns to some degree of normalcy, we are confident that there will be even greater appreciation for the power of adaptive, blended learning, and in particular, our ability to deliver those solutions, anywhere, at any time.  In all cases, leveraging both the power of software to provide personalized, adaptive instruction, while providing the data and information to empower a teacher or a tutor to provide impactful human instruction that so many are missing in this pandemic.”

First Quarter 2020 Review

Revenue: Total revenue in the first quarter of 2020 was $47.2 million, compared to $44.6 million in the first quarter of 2019, due to an increase in Lexia and Consumer Language revenue, partially offset by a slight decline in E&E Language revenue. Consolidated bookings were $33.6 million, an increase of 20% versus the first quarter of 2019. Revenue growth lags bookings growth.

Revenue at Lexia increased 18% year-over-year to $17.5 million. The increase in Lexia revenues was a result of continued demand for its product portfolio and the concentrated efforts of a direct sales team.  Literacy bookings increased by 22% over the prior year period on a consistently high renewal rate of 103% and a solid retention rate of 88%. Retention and renewal rates have been and will continue to be affected in the short-term by our decision to support our K-12 customers impacted by the COVID-19 pandemic. We decided to leave licenses on for customers even as license periods came to an end, and to not push customers to pay immediately. We expect retention and renewal rates will normalize, but in the interim our decision to accommodate customers during this time has produced higher than normal retention rates, because we aren’t turning schools off at their license end date, and lower than normal renewal rates, because we aren’t requesting immediate payment.

Consumer Language segment revenue increased $0.8 million, or 5%, year-over-year to $16.1 million, reflecting the recognition of sales growth efforts made in prior quarters. Consumer Language bookings totaled $22.6 million in Q1 2020, up $6.7 million, or 42%, year over year from $15.8 million. Consumer Language bookings increased primarily due to the sale of Lifetime subscriptions in the Web channel, but because those sales are recognized as revenue over 24-months, they did not have a significant impact on revenue in Q1 2020. Subscriptions with a duration of one year or less totaled 38% of the subscription unit mix at the end of the first quarter 2020, down from 45% at the end of the same quarter last year.

E&E Language segment revenue decreased 6% year-over-year to $13.6 million. E&E language bookings decreased $2.1 million, or 28%, year-over-year. The bookings decrease was driven by lower bookings in the Enterprise portion of the segment spread across, Corporate, Reseller and Affiliate. Included in the decline was a $0.6 million impact for a sale from last year that the customer cancelled in Q1 2020.

Net Loss:  In the first quarter 2020, the Company reported a net loss of $6.2 million, or $(0.26) per diluted share.  In the comparable period a year ago, the Company reported a net loss of $0.5 million, or $(0.02) per diluted share. The decline in net loss of $5.6 million was driven by an increase in all operating expense categories, as an increase in revenue was fully offset by an increase in cost of revenue. Total operating expenses increased $4.2 million, or 11% year-over-year, to $41.9 million, primarily due to higher online media expense and higher stock based compensation expense as we shift more variable compensation from cash-based to equity-based. Additionally, the year-over-year change in net loss was also impacted by two prior year non-recurring items related to a $1.4 million gain on sale of idle assets and a $0.6 million tax benefit related to the Virginia state adoption of 2017 Tax Reform.

Balance Sheet: The Company had cash and cash equivalents of $35.1 million and no debt outstanding at March 31, 2020. Deferred revenue totaled $164.0 million at March 31, 2020, compared to $177.6 million at December 31, 2019. Short-term deferred revenue before SourceNext and Custom Content, which will be recognized as revenue over the next 12 months, totaled $104.4 million, or approximately 78% of the combined total deferred revenue balance at March 31, 2020.

Free Cash Flow and Adjusted EBITDA: Net cash used in operating activities was $3.5 million in the first quarter of 2020 compared to $6.6 million in the first quarter last year. Free cash flow, a non-GAAP financial measure, was an outflow of $7.3 million in the first quarter 2020, compared to an outflow of $11.3 million in the same period a year ago.

Adjusted EBITDA, a non-GAAP financial measure, was $1.2 million in the first quarter 2020, a decline compared to $3.3 million in the year-ago period.
