ECARX Delivers ADAS Platform

to Global Car Manufacturers

SHANGHAI, China, November 6, 2023 -- ECARX Holdings Inc. (Nasdaq: ECX) ("ECARX"), a global provider of mobility technology, has today announced a new series of Advanced Driver Assistance System (ADAS) enabled products, starting with the ECARX Skyland Pro. It will support drivers as the autonomy of their vehicles increases.

Delivery of this ECARX ADAS platform has already taken place, with the beginning of its mass production marking a significant milestone for the company. Owing to its dual system-on-chip (SoC) architecture, ECARX Skyland Pro delivers exceptional performance, and is supported by a sophisticated safety system.

Empowered by two Black Sesame Huashan-2 A1000 automotive-grade SoCs that deliver a comprehensive computing power of 116 tera operations per second (TOPS) at 8-bit integer (INT8), the high-performance ECARX Skyland Pro enables L2+ advanced driving and parking.

In addition, the ECARX Skyland Pro platform supports industry-leading bird's-eye view (BEV) perception algorithms and a 5R10V sensor configuration. Through continuous over-the-air updates, ECARX Skyland Pro can enable more scenario-based solutions such as urban navigate-on-autopilot (NoA) capability and home-zone park assist (HPA).

Furthermore, ECARX Skyland Pro also boasts the following ADAS features: automatic emergency braking (AEB), lane-keeping assist (LKA), lane departure warning (LDW), blind spot detection (BSD), and electronic stability control (ESC) – all of which have achieved high scores in China - New Car Assessment Program (C-NCAP) preliminary testing under China’s stringent vehicle safety assessment program.

Besides its rich ADAS capabilities, ECARX Skyland Pro combines its dual SoC architecture with BlackBerry’s QNX, AUTOSAR Adaptive Platform and Classic Platform automotive-grade software to provide robust safety features that meet the requirements of global OEMs and regulators.

Testing and validation of system functionalities are major considerations in the development of ADAS solutions. To address these concerns, ECARX provides end-to-end testing, and a validation methodology and toolchain, therefore enabling its partners to significantly shorten the R&D cycle while mitigating risks and ensuring the reliability of ECARX’s ADAS solutions.

The launch of ECARX Skyland Pro will soon be followed by the introduction of ECARX Skyland, a single SoC solution that is able to meet a wider range of OEM needs. Tailored for L2+ ADAS scenarios, ECARX Skyland will allow auto makers to seamlessly combine driving and parking functionalities. Integrating a single Black Sesame Huashan-2 A1000 automotive-grade SoC, ECARX Skyland will enable peak computing power of up to 58 TOPS and support of a 5R6V sensor configuration, to provide more than 20 ADAS feature, including high-speed NoA driving assistance, automated parking assist (APA), and remote parking assist (RPA).

The mass production of ECARX Skyland Pro and the ECARX Antora 1000 Pro computing platforms has begun as ECARX delivers on its commitment to provide a comprehensive suite of automotive intelligence solutions that seamlessly merge outstanding performance with enhanced security. Through the ECARX Skyland series, car manufacturers will be able to effortlessly integrate cutting-edge ADAS capabilities into their vehicles, ultimately providing safe and efficient driving experiences to a broader audience.

ECARX Announces Third Quarter 2023 Financial Results

London, UK, November 9, 2023 — ECARX Holdings Inc. (Nasdaq: ECX) ("ECARX" or the “Company”), a global mobility tech provider, today announced unaudited financial results for the quarter ended September 30, 2023.

“With revenue up 50% year-on-year, ECARX has delivered yet another quarter of robust growth, driven by growing demand for increasingly sophisticated digital cockpit solutions,” said ECARX Chairman and CEO Ziyu Shen. “Our vertically integrated technology stack offers automakers flexible solutions that are fully customizable, enabling them to precisely tailor the customer experience. Together with the significant investments that we have made, this has helped us diversify our product portfolio and continue expanding our customer base beyond the Geely Group, and grow our business outside China. With six new design wins for flagship car models, we have set the foundations for long-term sustainable growth. As the automotive industry moves towards an all-electric, software-defined future, we are strengthening our strategic alliances with leading tech companies to support our customers in their global transformation.”

Third Quarter 2023 Financial Results:

• Total revenue of RMB1,080.0 million (US$148.0 million), up 50% year-over-year (“YoY”).

◦ Sales of goods revenue of RMB734.2 million (US$100.6 million), up 38% YoY, primarily driven by the ramp-up of new digital cockpit sales volumes and the shift in portfolio revenue mix from infotainment head units (IHUs) to digital cockpits, which have a higher total revenue per unit.

◦ Software license revenue of RMB136.6 million (US$18.7 million), up 73% YoY, mostly due to revenue generated from two procurement framework agreements for platform software and intellectual property licenses.

◦ Service revenue of RMB209.2 million (US$28.7 million), up 92% YoY, mostly due to the number and/or value of contracts completed this quarter compared to the same period last year.

• Total cost of revenue was RMB749.1 million (US$102.7 million), up 29% YoY, primarily driven by an increase in sales volume of new digital cockpits which have a higher total cost per unit.

• Gross profit of RMB330.9 million (US$45.3 million), up 140% YoY, giving a gross margin of 31%.

• Research and development expenses were RMB309.3 million (US$42.4 million), up 71% YoY as we continue to invest in our core product roadmap and international research and development expansion.

• Selling, general and administrative expenses and others, net were RMB260.2 million (US$35.7 million), up 42% YoY, primarily driven by our international expansion that started towards the end of Q3’2022 and higher share-based compensation expense during the quarter.

• Net loss of RMB281.2 million (US$38.6 million), up 8% YoY and 47% quarter-over-quarter (“QoQ”). The QoQ movement was primarily attributed to higher share-based compensation expense during the quarter, foreign currency exchange gains/losses and fair value changes to certain financial instruments.

• Adjusted EBITDA (non-GAAP) loss of RMB178.6 million (US$24.6 million), an improvement from a loss of RMB180.6 million from the same period last year.

• Total cash of RMB687.6 million (US$94.2 million), including RMB52.5 million (US$7.2 million) in restricted cash, as of September 30, 2023.

1/8

Translation of results into U.S. dollars

This announcement contains translations of certain Renminbi (RMB) amounts into U.S dollars (US$) at a specified rate solely for the convenience of the reader. Unless otherwise noted, the translation of Renminbi into U.S. dollars has been made at RMB7.2960 to US$1.00, the noon buying rate in effect on September 30, 2023 as set forth in the H.10 Statistical Release of The Board of Governors of the Federal Reserve System. We make no representation that any Renminbi or U.S. dollar amounts could have been, or could be, converted into U.S. dollars or Renminbi, as the case may be, at any particular rate, or at all.

Non-GAAP Financial Measure

The Company uses adjusted EBITDA (non-GAAP) in evaluating its operating results and for financial and operational decision-making purposes. Adjusted EBITDA is defined as net loss excluding interest income, interest expense, income tax expenses, depreciation of property and equipment, amortization of intangible assets, and share-based compensation expenses.

The Company presents the non-GAAP financial measure because it is used by the management to evaluate the Company’s operating performance and formulate business plans. The Company believes that the non-GAAP measure helps identify underlying trends in its business that could otherwise be distorted by the effects of foreign currency translation and certain expenses that are included in net loss. The Company also believes that the use of the non-GAAP measure facilitates investors’ assessment of its operating performance.

Adjusted EBITDA (non-GAAP) should not be considered in isolation or construed as alternatives to net loss or any other measures of performance or as indicators of the Company’s operating performance. Investors are encouraged to compare the Company’s historical adjusted EBITDA (non-GAAP) to the most directly comparable GAAP measure, net loss. Adjusted EBITDA (non-GAAP) presented here may not be comparable to similarly titled measures presented by other companies. Other companies may calculate similarly titled measures differently, limiting their usefulness as comparative measures to the Company’s data. The Company encourages investors and others to review the financial information in its entirety and not rely on a single financial measure.

For more information on the non-GAAP financial measure, please see the table captioned “Unaudited Reconciliation of GAAP and Non-GAAP Results”set forth at the end of this press release.

Unaudited Reconciliation of GAAP and Non-GAAP Results

Adjusted EBITDA

We use adjusted EBITDA in evaluating our operating results and for financial and operational decision-making purposes. Adjusted EBITDA is defined as net loss excluding interest income, interest expense, income tax expenses, depreciation of property and equipment, amortization of intangible assets, and share-based compensation expenses.

Adjusted EBITDA should not be considered in isolation or construed as alternatives to net loss or any other measures of performance or as indicators of our operating performance. Investors are encouraged to compare our historical adjusted EBITDA to the most directly comparable GAAP measure, net loss. Adjusted EBITDA presented here may not be comparable to similarly titled measures presented by other companies. Other companies may calculate similarly titled measures differently, limiting their usefulness as comparative measures to our data. We encourage investors and others to review our financial information in its entirety and not rely on a single financial measure.
