In other words, most developers are R&D employees in various companies and bring forth 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. 12 ESPRESSIF SYSTEMS | Q1 2023 REPORT | MANAGEMENT REPORT Ownership of Securities Basic information of securities Share types Ordinary share Share capital 80,492,619 (as of Mar 31, 2023) Listing Shanghai Stock Exchange (SSE) Ticker 688018.SH Listing Date 2019-07-22 Shareholder Structure as of Mar 31, 2023 Shareholder Share Numbers Percentage (%) Espressif (Hong Kong) Investment Ltd. 33,960,000 42.19 Dajia Life Insurance Co., Ltd. – Universal Products 2,602,353 3.23 Shinvest Holding Ltd. 2,546,100 3.16 ABC - Franklin Templeton Sealand Fund 1,784,545 2.22 Orient Securities -Zhonggeng Value Pioneer Fund 1,406,163 1.75 Ningbo Meishan Free Trade Port Le Tun Investment Management 1,046,030 1.30 Partnership (Limited Partnership) CITIC Securities Co., Ltd. 781,410 0.97 China Resources SZITIC Trust - Broadvision Selection II Fund 711,000 0.88 ABC - Franklin Templeton Sealand Fund 705,538 0.88 China Resources SZITIC Trust - Broadvision Selection Fund 687,000 0.85 Top 10 shareholders 46,230,139 57.43 Other public shareholders 34,262,480 42.57 Total of outstanding shares 80,492,619 100.00 13 ESPRESSIF SYSTEMS | Q1 2023 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, such as Silicon Labs and Nordic, may reduce our product sales and market share. Suppliers A signicant portion of the Company’s products is fabricated by the Taiwan Semiconductor Manufacturing Company Limited (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 30.8% in the rst quarter of 2023. 14 ESPRESSIF SYSTEMS | Q1 2023 REPORT | CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED) Consolidated Financial Statements (Unaudited) Consolidated Balance Sheet (Unaudited) CNY March 31, 2023 January 1, 2023 December 31, 2022 Assets Current assets: Cash and cash equivalents 324,630,351 350,677,354 350,677,354 Held for trading nancial assets 439,230,911 461,223,082 461,223,082 Notes receivable 2,742,270 789,099 789,099 Accounts receivable, net 227,751,114 198,406,116 198,406,116 Accounts receivable, nancing 6,460,424 1,441,520 1,441,520 Prepayments 10,240,868 9,724,045 9,724,045 Other receivables 9,735,746 9,578,753 9,578,753 Including: Interest receivable 1,693,509 838,168 838,168 Inventories 385,272,779 448,981,896 448,981,896 Other current assets 197,216,305 228,089,444 228,089,444 Total current assets 1,603,280,767 1,708,911,310 1,708,911,310 Non-current assets: Debt investment 304,474,500 212,484,600 212,484,600 Investment in other equity assets 35,340,648 35,340,648 35,340,648 Other non-current nancial assets 19,879,347 19,879,347 19,879,347 Fixed assets 63,236,168 60,243,507 60,243,507 Construction work in progress Right-of-use assets 23,860,940 21,692,767 21,692,767 Intangible assets 2,217,562 2,412,317 2,412,317 Long-term deferred expenses 7,826,380 6,565,887 6,565,887 Deferred income tax assets 29,334,823 18,987,186 15,266,444 Total assets 2,089,451,135 2,086,517,567 2,082,796,825 0 0 15 ESPRESSIF SYSTEMS | Q1 2023 REPORT | CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED) Consolidated Balance Sheet (Unaudited) CNY March 31, 2022 January 1, 2023 December 31, 2022 Liabilities & Shareholders’ Equity Current liabilities: Accounts payable 81,544,639 77,918,867 77,918,867 Contract liabilities 11,623,624 9,044,287 9,044,287 Payroll payable 33,662,927 85,041,335 85,041,335 Taxes payable 12,700,000 5,211,995 5,211,995 Other payable 9,534,556 2,925,552 2,925,552 Non-current liabilities due within one year 11,645,314 9,607,030 9,607,030 Other current liabilities 930,084 778,437 778,437 Total current liabilities 161,641,144 190,527,502 190,527,502 Non-current liabilities: Lease liabilities 13,320,777 12,839,126 12,839,126 Provisions 603,625 Deferred income tax liabilities 58,036,882 56,473,404 52,752,662 Total liabilities 233,602,428 259,840,032 256,119,290 Owners’ equity (or shareholders' equity): Share capital 80,492,619 80,484,430 80,484,430 Capital reserves 1,313,157,066 1,309,813,001 1,309,813,001 Less: Treasury stock 40,966,012 40,966,012 40,966,012 Other comprehensive income 11,677,862 16,946,374 16,946,374 Surplus reserves 46,570,910 46,570,910 46,570,910 Retained earnings 444,916,262 413,828,832 413,828,832 Total shareholders’ equity 1,855,848,707 1,826,677,535 1,826,677,535 Total liabilities and shareholders' equity 2,089,451,135 2,086,517,567 2,082,796,825 N.B.: Starting from 2023, the company will implement the "Accounting Treatment for Deferred Income Tax Related to Asset and Liability Arising from a Single Transaction That Does Not Qualify for Initial Recognition Exemption" as stipulated in Interpretation No. 16 of the Enterprise Accounting Standards issued by the Ministry of Finance.
