 “We had a strong finish in 2020 and we are off to an excellent start for 2021,” said Georges Karam, CEO of Sequans. “Our fourth quarter revenue growth exceeded our target, even as demand related to portable routers began to return to pre-COVID levels, leading to year-over-year growth of almost 65%. Some of our most important accomplishments in 2020 included the strengthening of our go-to-market capabilities via relationships with new distributors and MCU partners, extending our technology leadership by introducing the second generation of our Monarch platform, and reaching important milestones in our 5G development, which is expected to create another major growth engine for the company. Several of these initiatives are already making a positive contribution and all will help sustain our momentum as time goes on, and support our goal of an average of 50% annual growth for the five-year period beginning in 2020.
 
 “We are entering 2021 with the highest-ever level of backlog, driven by strong demand in the Massive IoT business. Since the end of 2020, we have secured several key Massive IoT design wins within our strong pipeline of developing business which will help offset lower revenue related to portable routers in 2021 and support our long-term growth objectives.”
 
 Q1 2021 Outlook
 
 The following statement is based on management’s current assumptions and expectations and assumes no increase in the severity or duration of the COVID-19 pandemic. This statement is forward-looking and actual results may differ materially.
 
 Overall demand, driven mainly by Massive IoT, continues to be strong and supports the company’s short and long-term growth targets despite the already-anticipated reduction in the portable router business. Management expects Q1 2021 revenue to follow the company’s typical seasonal pattern of a decline compared to Q4; management has decided not to give specific quarterly guidance in view of the potential impact of industry-wide supply chain bottlenecks, which could delay some shipments.
