Therefore, the net income was CNY 83.85 million, which marked a decrease of 43.41% year-on-year, mainly due to our increased R&D expenditure. The overall gross margin was 40.04%, in which the IoT chip gross margin was 48.18%. The overall gross margin decreased, due to the increased proportion of module sales. Customers in China’s mainland prefer purchasing chips, while the customers from the rest of the world prefer modules. We keep the chip margin at a reasonable level, in order to support our future R&D expenditure.

In other words, most developers are R&D employees in various companies and bring about business opportunities from the companies they work for. This way, the developer ecosystem we have created at Espressif demonstrates how the value of networks can grow exponentially: The more developers we attract as customers, the more hardware and software solutions we generate. The more successful hardware and software solutions we create, the more our reputation spreads with positive feedback from happy customers/developers. The above-mentioned interaction between people in our network prompts the creation of more content, which -in turn- attracts more users/developers searching for new content. Likewise, other third-party development platforms join our ecosystem and bring in new developers, as our inuence continues to grow. Having successfully applied the B2D2B model, Espressif can now focus on R&D investments, while maintaining a small business team that supports a large number of customers directly. In fact, most of our revenue is gained through direct sales. 11 ESPRESSIF SYSTEMS | Q3 2022 REPORT | MANAGEMENT REPORT Ownership of Securities Basic information of securities Share types Ordinary share Share capital 80,451,785 (as of Sep 30, 2022) Listing Shanghai Stock Exchange (SSE) Ticker 688018.SH Listing Date 2019-07-22 Shareholder Structure as of Sep 30, 2022 Shareholder Share Numbers Percentage (%) Espressif (Hong Kong) Investment Ltd. 34,860,000 43.33 Shinvest Holding Ltd. 2,804,446 3.49 Dajia Life Insurance Co., Ltd. – Universal Products 2,321,738 2.89 Yadong Beichen Investment Management Co., Ltd. 1,714,066 2.13 BOC - Franklin Templeton Sealand Fund 1,491,444 1.85 Ningbo Meishan Free Trade Port Le Tun Investment Management 1,046,030 1.30 Partnership (Limited Partnership) China Resources SZITIC Trust - Broadvision Selection II Fund 725,500 0.90 China Resources SZITIC Trust - Broadvision Selection Fund 718,000 0.89 CITIC Securities Co., Ltd. 672,776 0.84 ABC - Franklin Templeton Sealand Fund 670,416 0.83 Top 10 shareholders 47,024,416 58.45 Other public shareholders 33,427,369 41.55 Total of outstanding shares 80,451,785 100.00 12 ESPRESSIF SYSTEMS | Q3 2022 REPORT | MANAGEMENT REPORT Risks and Uncertainties Financial Risk The Company performs periodic credit evaluations of its customers’ nancial condition and generally requires of its customers no collateral. 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 the 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 certain period of time, which could have an adverse effect 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 25.8% in the rst three quarters of 2022, and it has been shrinking over the years. None of the customers accounted for yielded more than 10% of our revenue during the rst three quarters of the current scal year (2022). 13 ESPRESSIF SYSTEMS | Q3 2022 REPORT | CONSOLIDATED FINANCIAL
