The Internet of Things industry is still growing, but the rst quarter of 2022 was an o-peak period for the company. In addition, the ongoing global pandemic and the impact of the Omicron D variant, in particular, resulted in extended lockdowns for several Chinese cities, which has aected the downstream demand. Thus, the company sales increased only slightly compared with last year's same period. The gross margin for the reporting period was eveloper 41.04%. Research and Development Expenses The R&D expenditure in Q1 2022 was CNY 74.85 million, that is, 27.10% up compared with the same period of last year. In fact, the company's development expanded B signicantly and it now includes the integration of "Wireless SoC + AI + Software + Cloud", which has required substantial R&D investment. At the same time, the company is focused on improving the eciency of its research-and-development, with the aim to usiness speed up the release of new products. The two series of chips released in 2020, ESP32- S3 and ESP32-C3, have contributed to the company’s nancial performance in Q1 2022, and the three new chips released in 2021, ESP32-H2, ESP32-C2 and ESP32-C6, will enter the stage of mass production and marketing promotion soon. Our cloud platform, ESP Rainmaker, will also contribute to the revenue that will be accumulated throughout 2022. Inventories The closing inventory balance at the end of Q1 2022 was CNY 396.18 million, thus increasing by 21.46% since the end of the previous year. Considering the following factors collectively, the company has maintained an active stocking strategy, while raw materials and nished products increased during the reporting period. We expect that wafer supply will remain tight in the current year. We continue to explore new business opportunities, such as enterprise-wide business applications (e.g., industrial automation, healthcare, energy control, etc.) which have already started integrating Internet connectivity into their oerings. Additionally, it is expected that consumption by individuals will recover as soon as the pandemic is controlled in China. The life cycle of Espressif products is fairly long. We provide alongevity commitment of up to 12 years, and the company is strong enough to manage any inventory backlog. The cumulative inventory has led to a net cash outow from operating activities during the rst quarter of 2022. 5 ESPRESSIF SYSTEMS|Q1 2022 REPORT| MANAGEMENT REPORT Management Report Business Strategy Espressif Systems’ business strategy emanates from our four key capabilities and our four key services/products.

The Company provides an allowance for expected credit losses based on the net amount expected to be collected on such receivables. Losses have not been signicant for any of the periods presented. R&D Risk Espressif’s research and development strategy is focused on leveraging new technologies for the creation of innovative AIoT products. Any delays or changes in the development of these technologies by our industry partners, or a failure of our products to achieve market acceptance could compromise our competitive position. Competitors As the market for AIoT products grows, we face an increasing antagonism from relatively large competitors, such as Realtek, MediaTek, Inneon, NXP, Qualcomm and others. Intense competition from current players as well as new entrants may reduce our product sales and market share. Suppliers A signicant portion of the Company’s products is fabricated by Taiwan Semiconductor Manufacturing Co. (TSMC). The inability of TSMC to deliver wafers to the Company in a timely manner could impact the production of the Company’s products for a substantial period of time, which could have an adverse eect on the Company’s business, nancial condition, results of operations and cash ow. Customers The Company sells directly to end customers, distributors, solution providers and contract manufacturers. Our customers are a mix of several big customers and numerous small customers. The concentration ratio for our top-ve customers was 29.05%, 42.18% and 50.96% during the scal years of 2021, 2020 and 2019, respectively. None of the customers accounted for greater than 10% of our revenue during the scal year of 2021. 9 ESPRESSIF SYSTEMS|Q1 2022 REPORT| FINANCIAL STATEMENTS (UNAUDITED) Financial Statements (Unaudited)
