Business Highlights

New York and Vienna, VA – March 16, 2020 – Kaleyra, Inc. (NYSE American: KLR) (KLR WS) (“Kaleyra” or the “Company”) a rapidly growing cloud communications software provider delivering a secure system of application programming interfaces (APIs) and connectivity solutions in the API/Communications Platform as a Service (CPaaS) market, today reported its U.S. GAAP financial results for the year ended December 31, 2019.

“We ended 2019 on a high note, reporting record revenue of nearly $130 million, adding several new high-profile U.S. customers and boosting margins by increasing our mix of higher margin revenue streams such as voice,” commented Dario Calogero, Kaleyra’s Founder and Chief Executive Officer. “While new customers continue to represent important vehicles for future growth, organic growth opportunities, including innovating and strengthening our product portfolio continue to create a stable and growing base of revenue, particularly in North America and Asia-Pacific with the communications platforms we acquired in 2018. For 2019, 86% of revenues was from customers that have been on our communications platform /API for at least a year. We continue to see volume increases driven by the higher number of digital transactions made by end-users and by the increasing penetration rate of digital payments in the underlying payments markets. Improved top-line performance, coupled with a continuous steady improvement in our gross margin, which is led by the introduction of new voice products that have higher profitability, helped us achieve our 2019 fiscal year goals. This included becoming a public company by way of a business combination in November 2019 and achieving the full earnout targets of 30% (where the threshold was 24%) revenue and 45% pro forma Adjusted EBITDA year-over-year growth.”

Recent Business Highlights

Kaleyra’s subsidiary, Campaign Registry Inc., continues its trial with a major U.S. based telecommunications customer to reduce spam by collecting robotically driven campaign information from messaging companies and process and share that information with mobile operators and the messaging ecosystem as appropriate. A new, sanctioned ecosystem for businesses will be established to communicate with their customers using 10 Digit Long Code (“10 DLC”) services. The benefit will be increased reliability and quality for message senders as well as less unwanted messages in the form of spam for mobile users. Kaleyra has executed a $15 million fixed purchase order with a U.S. headquartered global mega-cap media customer in February 2020. The revenue will be realized over the course of 2020.

With the emergence of COVID-19, Kaleyra is collaborating with the Italian Red Cross to provide a text messaging service (Short Code number 4353535) to allow citizens to book, through an SMS, the home delivery of medicine, groceries and health care transport without further burdening an already saturated toll-free number. Kaleyra will receive the SMS from the citizens and will send a report to the Italian Red Cross who will take charge of the requests.

“The CPaaS marketplace offers tremendous potential for growth, and with our expanding footprint in the United States, recent listing on the NYSE American stock exchange and expanding blue-chip customer base, we look forward to a strong trajectory of growth ahead,” added Mr. Calogero. “Our experience and reputation within the financial services industry has earned us a reputation as a trusted CPaaS provider and this is providing new business opportunities on a worldwide basis. We are just beginning to penetrate

the U.S. market where we have added multiple new contracts over the last several months that have significant revenue potential. This will help drive revenue growth and margin expansion. With our innovative technology, product leadership, global revenue growth as well as a strengthened capital structure as a public company, Kaleyra is poised for significant global growth and shareholder value creation within the consolidating Cloud Communications for Enterprises market by both organic and strategic means.”

Outlook

Due to the uncertain and evolving public health outlook resulting from COVID-19, particularly as it relates to our business in Italy, Kaleyra is currently reviewing its 2020 annual guidance. While our results for January and February have been in line with our projections, beginning in March we have seen some volatility in our banking and payments business. The current and preliminary guidance reflects the limited visibility we have into this evolving situation and is most certainly subject to change. Despite these near-term headwinds, we are confident in our strategic course and long-term opportunity both in Italy as well as in Asia Pacific and North America, where, as of the date of this release, we have not yet seen an impact. In the longer term we foresee an acceleration of the digital transformation of many industries, which could have a positive impact on the volume of the services provided by Kaleyra.

For the fiscal year 2020, ending December 31, 2020, taking into effect the current and evolving situation with regard to COVID-19, the Company currently expects the following:

The foregoing guidance is based on current expectations. These statements are forward looking, and actual results may differ materially. Please see the Safe Harbor Statement in this earnings release for a description of certain important risk factors that could cause actual results to differ, and refer to Kaleyra’s most recent annual and quarterly reports on file with the Securities and Exchange Commission (SEC) for a more complete description of these risks. Furthermore, our outlook excludes items that may be required by U.S. GAAP, including, but not limited to, restructuring and related costs, acquisition or disposal related costs, expenses or income from certain legal actions, settlements and related costs outside our normal course of business, impairments of other long-lived assets, depreciation and amortization, extraordinary items, as well as the expensing of stock options and restricted stock grants. We do not intend to update this guidance as a result of developments occurring after the date of this release.
