Business Model
Business-to-Developer-to-Business (B2D2B)
Espressif has deployed the Business-to-Developer type of marketing, not only because it has gained prominence in
recent years, but also because it has proven to be more e fective since the influence of developers on organizations
of all sizes has gained traction. 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 a tract as customers, the more hardware and so tware solutions we generate.
The more successful hardware and so tware 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- a tracts more users/developers searching for new content.
Likewise, other third-party development pla forms join our ecosystem and bring in new developers, as our
influence continues to grow.
Having successfully applied the B D B 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.

Risks and Uncertainties
Financial Risk
The Company performs periodic credit evaluations of its customers’ financial
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
significant for any of the periods presented in this report.
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, Infineon, 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 significant portion of the Company’s products is fabricated by theTaiwan
Semiconductor Manufacturing Company Limited (TSMC).The inability ofTSMC
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 e fect on the Company’s business, financial condition, results of
operations and cash flow.
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-five customers
was 28.1% in 2023.

disposal obligations and corresponding related assets that were recognized due to the application of this standard on the initial period reported in the financial
statements when the standard was first implemented. If there are temporary di ferences that result in taxable or deductible amounts related to the above-mentioned

ESPRESSIF SYSTEMS | 2023 ANNUAL REPORT | FURTHER INFORMATION
Other Information
The management of Espressif Systems (Shanghai) Co., Ltd. (henceforth, “the management”) is responsible for any
information on all aspects of the 2023 company report, apart from the financial statements and the auditor’s report
on them.
Our opinions on the financial statements and the group management report do not cover the rest of the information
provided here, and consequently we do not express an opinion or any other form of assurance conclusion thereof.
In connection with our audit, our responsibility is to read the rest of the information provided and, in so doing,
consider whether this information:
> is materially inconsistent with the consolidated financial statements, with the group management report information
audited for content or our knowledge obtained in the audit, or
> appears to be materially misstated.
If, based on the work we have performed, we conclude that there is a material misstatement of this other
information, we are required to report that fact. However, we have nothing to report in this regard.
Management's Responsibilities for the Financial
Statements
The management is responsible for the preparation of financial statements that give a true and fair view, in
accordance with the ASBE, and for the design, implementation and maintenance of such internal controls as the
management deems necessary, to enable the preparation of financial statements that are free from material
misstatements, whether due to fraud or error.
In preparing the financial statements, the management is responsible for assessing the Company’s ability to continue
its operation, disclosing, as applicable, any ma ters related to ongoing concerns and using them as the basis of
accounting, unless the management either intends to liquidate the Company or cease its operations, having no
realistic alternative but to do so.
Auditor’s Responsibilities for the Auditing of the
Financial Statements
Our objectives are to obtain reasonable assurances about whether the financial statements as a whole are free from
material misstatements, due to either fraud or errors, and to issue an auditor’s report that includes our true opinion.
Reasonable assurances provide a high level of confidence, but are not a guarantee that an audit conducted in
accordance with CSAs will always detect a material misstatement when and where it exists.
Misstatements can arise from fraud or errors and are considered substantial if, individually or in aggregate, they could
reasonably be expected to influence the economic decisions of users, taken on the basis of these financial
statements.
As part of an audit in accordance with CSAs, we exercise our professional judgment and maintain professional
skepticism throughout the audit. We also:
ESPRESSIF SYSTEMS | 2023 ANNUAL REPORT | FURTHER INFORMATION
> Identify and assess the risks of substantial financial misstatements, due to either fraud or errors; design and
perform auditing procedures in response to those risks, and obtain auditing evidence that is su ficient and
appropriate for providing a basis for our opinion.The risk of not detecting a material misstatement resulting from
fraud is higher than one resulting from error, as fraud may involve collusion, forgery, intentional omissions,
misrepresentations, or the override of internal controls.
> Obtain an understanding of internal controls relevant to the audit, in order to design auditing procedures that are
appropriate to the circumstances.
> Evaluate the appropriateness of accounting policies used and the reasonableness of accounting estimates and
related disclosures made by the management.
> Conclude on the appropriateness of the management’s use of a growing concern as the basis of accounting and,
according to the auditing evidence obtained, determine whether a substantial uncertainty exists about events or
conditions that may cast a significant doubt on the Company’s ability to continue its operation. If we conclude that
there is substantial uncertainty, we are required to draw users’ a tention to our auditor’s report on the related
disclosures in the financial statements or, if such disclosures are inadequate, to modify our opinion. Our conclusions
are based on the auditing evidence obtained up until the date of our auditor’s report. However, future events or
conditions may force the Company to cease its operation altogether.
> Evaluate the overall presentation, structure and content of the financial statements, including the disclosures, and
determine whether the financial statements represent the underlying transactions and events in a manner that
achieves a fair presentation.
> Obtain su ficient and appropriate auditing evidence about the financial information of entities or business activities
of the Company, in order to express our auditing opinion on the Company’s consolidated financial statements. We are
responsible for directing, supervising and executing group audits and assume full responsibility for auditing opinions.
We communicate with those charged with governance, among other ma ters, on the planned auditing scope, timing
and significant audit findings, including any significant deficiencies in internal controls that we may identify during
our audit.
We also provide those charged with governance with a statement that we have complied with all relevant ethical
requirements regarding our independence, and we also communicate with them all relationships and other ma ters
that may reasonably be thought to bear on our independence and, where applicable, any other related protections.
From the ma ters communicated to those charged with governance, we determine which ma ters are of the highest
significance in the auditing of the financial statements of the current period and are, therefore, the key auditing
findings. We describe these findings in our auditor’s report, unless a law or regulation prohibits such public
disclosure about those findings, or when -in extremely rare circumstances- we determine that a finding should not
be communicated in our report, because the adverse consequences of its disclosure would reasonably be
expected to outweigh the benefits of such communication for the public interest.
