H1 net revenues $5.28 billion; gross margin 33.5%; operating loss of $130 million, including $198 million related to impairment, restructuring charges and other related phase-out costs; net loss of $41 million
Business outlook at mid-point: Q3 net revenues of $3.17 billion and gross margin of 33.5%

Geneva, July 24, 2025 – STMicroelectronics N.V. ("ST") (NYSE:STM), a global semiconductor leader serving customers across the spectrum of electronics applications, reported U.S. GAAP financial results for the second quarter ended June 28, 2025. This press release also contains non-U.S. GAAP measures (see Appendix for additional information).

ST reported second quarter net revenues of $2.77 billion, gross margin of 33.5%, operating loss of $133 million, and net loss of $97 million or -$0.11 diluted earnings per share (non-U.S. GAAP¹ operating income of $57 million, and non-U.S. GAAP¹ net income of $57 million or $0.06 diluted earnings per share).

Jean-Marc Chery, ST President & CEO, commented:

"Q2 net revenues came above the mid-point of our business outlook range, driven by higher revenues in Personal Electronics and Industrial, while Automotive was slightly below expectations. Gross margin was in line with the mid-point of our business outlook range."
"On a year-over-year basis, Q2 net revenues decreased 14.4%, non-U.S. GAAP¹ operating margin decreased to 2.1% from 11.6% and non-U.S. GAAP¹ net income decreased to $57 million from $353 million."
"First half net revenues decreased 21.1% year-over-year, with a decrease in all reportable segments. Non-U.S. GAAP¹ operating margin was 1.3% and non-U.S. GAAP¹ net income was $120 million."
"In the second quarter, our book-to-bill ratio remained above one for Industrial, while Automotive was below parity. Bookings continued to increase sequentially."
"Our third quarter business outlook, at the mid-point, is for net revenues of $3.17 billion, decreasing year-over-year by 2.5% and increasing sequentially by 14.6%; gross margin is expected to be about 33.5%; including about 340 basis points of unused capacity charges. On a sequential basis, our Q3 gross margin will be negatively impacted by about 140 basis points, mainly from currency effect and, to a lesser extent, the start of non-recurring cost related to our manufacturing reshaping program."
"While we expect Q3 revenues to show a solid sequential growth enabling a continued year-over-year improvement, we are still operating amid an uncertain macroeconomic environment. Given these external factors, our priorities remain supporting our customers, accelerating new product introductions, and executing our company-wide program to reshape our manufacturing footprint and resize our global cost base."

Changes to reportable segments

Following ST's reorganization announced in January 2024 into two Product Groups and four reportable segments, we have made further progress in analyzing our global product portfolio, resulting in the following adjustments to our segments, effective starting January 1, 2025, without modifying subtotals at Product Group level:

In Analog, Power & Discrete, MEMS and Sensors (APMS) Product Group:
- The transfer of VIPower products from Power and Discrete products ("P&D") reportable segment to Analog products, MEMS and Sensors ("AM&S") reportable segment.
In Microcontrollers, Digital ICs and RF products (MDRF) Product Group:
- the newly created ‘Embedded Processing' ("EMP") reportable segment includes the former ‘MCU' segment (excluding the RF ASICs mentioned below) as well as Custom Processing products (Automotive ADAS products).
- the newly created ‘RF & Optical Communications' ("RF&OC") reportable segment includes the former ‘D&RF' segment (excluding Automotive ADAS products) as well as some RF ASICs which were previously part of the former ‘MCU' segment.

We believe these adjustments are critical for implementing synergies and optimizing resources, which are necessary to fully deliver the benefits expected from our new organization.

Our four reportable segments - within each Product Group - are now as follows:

In Analog, Power & Discrete, MEMS and Sensors (APMS) Product Group:
- Analog products, MEMS and Sensors ("AM&S") reportable segment, comprised of ST analog products (now including VIPower products), MEMS sensors and actuators, and optical sensing solutions.
- Power and Discrete products ("P&D") reportable segment, comprised of discrete and power transistor products (now excluding VIPower products).

In this Press Release, "Analog" refers to analog products, "MEMS" to MEMS sensors and actuators and "Imaging" to optical sensing solutions.

In Microcontrollers, Digital ICs and RF products (MDRF) Product Group:
- Embedded Processing ("EMP") reportable segment, comprised of general-purpose and automotive microcontrollers, connected security products and Custom Processing Products (Automotive ADAS)
- RF & Optical Communications ("RF&OC") reportable segment, comprised of Space, Ranging & Connectivity products, Digital Audio & Signaling Solutions and Optical & RF COT.

In this Press release, "GPAM" refers to General purpose & automotive microcontrollers, "Connected Security" to connected security products, "Custom Processing" to automotive ADAS products.

Prior year comparative periods have been adjusted accordingly.

Supplemental Non-U.S. GAAP Financial Information

U.S. GAAP – Non-U.S. GAAP Reconciliation

The supplemental non-U.S. GAAP information presented in this press release is unaudited and subject to inherent limitations. Such non-U.S. GAAP information is not based on any comprehensive set of accounting rules or principles and should not be considered as a substitute for U.S. GAAP measurements. Also, our supplemental non-U.S. GAAP financial information may not be comparable to similarly titled non-U.S. GAAP measures used by other companies. Further, specific limitations for individual non-U.S. GAAP measures, and the reasons for presenting non-U.S. GAAP financial information, are set forth in the paragraphs below. To compensate for these limitations, the supplemental non-U.S. GAAP financial information should not be read in isolation, but only in conjunction with our consolidated financial statements prepared in accordance with U.S. GAAP.

ST believes that these non-U.S. GAAP financial measures provide useful information for investors and management because they offer, when read in conjunction with ST's U.S. GAAP financials, (i) the ability to make more meaningful period-to-period comparisons of ST's on-going operating results, (ii) the ability to better identify trends in ST's business and perform related trend analysis, and (iii) to facilitate a comparison of ST's results of operations against investor and analyst financial models and valuations, which may exclude these items.

Non-U.S. GAAP Operating Income, Non-U.S. GAAP Net Earnings and Non-U.S. GAAP Earnings Per Share (non-U.S. GAAP measures)

Operating income before impairment and restructuring charges and one-time items is used by management to help enhance an understanding of ongoing operations and to communicate the impact of the excluded items, such as impairment, restructuring charges and other related phase-out costs. Adjusted net earnings and earnings per share (EPS) are used by management to help enhance an understanding of ongoing operations and to communicate the impact of the excluded items like impairment, restructuring charges and other related phase-out costs attributable to ST and other one-time items, net of the relevant tax impact.

Net Financial Position and Adjusted Net Financial Position (non-U.S. GAAP measures)

Net Financial Position, a non-U.S. GAAP measure, represents the difference between our total liquidity and our total financial debt. Our total liquidity includes cash and cash equivalents, restricted cash, if any, short-term deposits, and marketable securities, and our total financial debt includes short-term debt and long-term debt, as reported in our Consolidated Balance Sheets. ST also presents adjusted net financial position as a non-U.S. GAAP measure, to take into consideration the effect on total liquidity of advances received on capital grants for which capital expenditures have not been incurred yet.

ST believes its Net Financial Position and Adjusted Net Financial Position provide useful information for investors and management because they give evidence of our global position either in terms of net indebtedness or net cash by measuring our capital resources based on cash and cash equivalents, restricted cash, if any, short-term deposits and marketable securities and the total level of our financial debt. Our definitions of Net Financial Position and Adjusted Net Financial Position may differ from definitions used by other companies, and therefore, comparability may be limited.

(US$ m)	Jun 28 2025	Mar 29 2025	Dec 31 2024	Sep 28 2024	Jun 29 2024

Net Capex and Free Cash Flow (non-U.S. GAAP measures)

ST presents Net Capex as a non-U.S. GAAP measure, which is reported as part of our Free Cash Flow (non-U.S. GAAP measure), to take into consideration the effect of advances from capital grants received on prior periods allocated to property, plant and equipment in the reporting period.

Net Capex, a non-U.S. GAAP measure, is defined as (i) Payment for purchase of tangible assets, as reported plus (ii) Proceeds from sale of tangible assets, as reported plus (iii) Proceeds from capital grants and other contributions, as reported plus (iv) Advances from capital grants allocated to property, plant and equipment in the reporting period.

ST believes Net Capex provides useful information for investors and management because annual capital expenditures budget includes the effect of capital grants. Our definition of Net Capex may differ from definitions used by other companies.

(US$ m)	Q2 2025	Q1 2025	Q4 2024	Q3 2024	Q2 2024
Payment for purchase of tangible assets, as reported	(574)	(587)	(584)	(669)	(690)
Proceeds from sale of tangible assets, as reported	4	2	-	2	1
Proceeds from capital grants and other contributions, as reported	89	47	83	66	143
Advances from capital grants allocated to property, plant and equipment	16	8	31	36	18
Net Capex (non-U.S. GAAP)	(465)	(530)	(470)	(565)	(528)

Free Cash Flow, which is a non-U.S. GAAP measure, is defined as (i) net cash from operating activities plus (ii) Net Capex plus (iii) payment for purchase (and proceeds from sale) of intangible and financial assets and (iv) net cash paid for business acquisitions, if any.

ST believes Free Cash Flow provides useful information for investors and management because it measures our capacity to generate cash from our operating and investing activities to sustain our operations.

Free Cash Flow reconciles with the total cash flow and the net cash increase (decrease) by including the payment for purchases of (and proceeds from matured) marketable securities and net investment in (and proceeds from) short-term deposits, the net cash from (used in) financing activities and the effect of changes in exchange rates, and by excluding the advances from capital grants received on prior periods allocated to property, plant and equipment in the reporting period. Our definition of Free Cash Flow may differ from definitions used by other companies.
