NAAC North Atlantic Acquisition Corporation

TeleSign, the leading provider of Digital Identity and Communications solutions, today released preliminary financial results for the year and fourth quarter ended December 31, 2021.

“Our strong full-year and fourth quarter performance represents another important step in TeleSign’s journey to become the global leader in Digital Identity,” said Joe Burton, TeleSign’s Chief Executive Officer. “The combination of strong demand in our Digital Identity segment coupled with pricing discipline in Communications enabled us to exceed our full-year Gross Profit target. We are particularly pleased with the Digital Identity segment’s performance in the fourth quarter, which increased its revenue by over 45 percent year-over-year. These results are further validation of TeleSign’s unique solution and ensure the company is well positioned to achieve our previously disclosed 2022 targets.”

TeleSign and North Atlantic Acquisition Corporation (NASDAQ: NAAC), a publicly traded special purpose acquisition company, previously announced the signing of an agreement and plan of business combination expected to close in mid-2022.

“We are delighted with TeleSign’s performance in the fourth quarter, which reflects the sizable opportunity ahead,” said Gary Quin, NAAC’s Chief Executive Officer. “The company continues to drive impressive growth in the Digital Identity and Communications space, which we expect to generate significant shareholder value.”

2021 Full-Year and Fourth Quarter Financial Highlights

• Full-year 2021 consolidated revenue increased 23.0 percent year-over-year. Full-year 2021 Gross Profit increased 3.2 percent year-over-year and 7.6 percent on a constant currency basis.
• Fourth quarter 2021 consolidated revenue increased 10.4 percent year-over-year. Fourth quarter 2021 Gross Profit increased 12.1 percent year-over-year and 1.8 percent on a constant currency basis.
• Full-year 2021 and fourth quarter 2021 Digital Identity revenue increased 27.4 percent and 45.7 percent year-over-year, respectively, due to strong demand for high-margin value-added services from existing and new customers.
• Full-year 2021 and fourth quarter 2021 Communications revenue increased 22.6 percent and 7.5 percent year-over-year, respectively. The segment’s fourth quarter revenue growth was slower than the full-year, as we focused less on certain international business activities that were not meeting our profitability targets. Based on our sales pipeline and anticipated growth within our existing customer base, we remain confident about our overall revenue growth targets.
