Insights

Equity Analyst

Q3 shows sequential recovery but weaker year‑over‑year margins; outlook implies gradual market improvement and cost reshaping.

ST reported $3.19 billion in Q3 revenue, up sequentially yet down 2.0% year‑over‑year, with gross margin at 33.2% and U.S. GAAP operating income of $180 million (non‑U.S. GAAP operating income $217 million). The business mechanical drivers are a sequential demand rebound concentrated in Personal Electronics and AM&S growth, offset by significant weakness in Power & Discrete where revenue fell 34.3% and an operating loss emerged; inventory sits at $3.17 billion with days sales of 135 days.

Key dependencies and risks include the execution of the manufacturing reshaping program (which generated $37 million of charges this quarter), the degree to which capacity reservation dynamics and manufacturing efficiency recover, and the closing/integration of the announced MEMS acquisition (up to $950 million) now expected to close in H1 2026. Watch the upcoming quarter for the company’s ability to convert the book‑to‑bill >1 into durable margin expansion and for gross margin guidance centered at 35.0% (mid‑point) and the impact of ~290 basis points of unused capacity charges on that figure within the next quarter.

STMicroelectronics Reports 2025 Third Quarter Financial Results

• Q3 net revenues $3.19 billion; gross margin 33.2%; operating income of $180 million, including $37 million related to impairment, restructuring charges and other related phase-out costs; net income of $237 million
• Business outlook at mid-point: Q4 net revenues of $3.28 billion and gross margin of 35.0%  

Geneva, October 23, 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 third quarter ended September 27, 2025. This press release also contains non-U.S. GAAP measures (see Appendix for additional information).
 
ST reported third quarter net revenues of $3.19 billion, gross margin of 33.2%, operating income of $180 million, and net income of $237 million or $0.26 diluted earnings per share (non-U.S. GAAP¹ operating income of $217 million, and non-U.S. GAAP¹ net income of $267 million or $0.29 diluted earnings per share).


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

• “Q3 net revenues came slightly above the mid-point of our business outlook range, with higher revenues in Personal Electronics, while Automotive and Industrial performed as anticipated, and CECP was broadly in line with expectations. Gross margin was slightly below the mid-point of our business outlook range mainly due to product mix within Automotive and Industrial.”
• “On a year-over-year basis, Q3 net revenues decreased 2.0%, non-U.S. GAAP¹ operating margin decreased to 6.8% from 11.7% and non-U.S. GAAP¹ net income decreased to $267 million from $351 million.”
• “In the third quarter, our book-to-bill ratio was above one, with Automotive above parity and Industrial at parity.”
• “Our fourth quarter business outlook, at the mid-point, is for net revenues of $3.28 billion, increasing sequentially by 2.9%, gross margin is expected to be about 35.0%; including about 290 basis points of unused capacity charges.”
• “The mid-point of this outlook translates into full year 2025 revenues of about $11.75 billion. This represents a 22.4% growth in the second half compared to the first half, confirming signs of market recovery. Gross margin is expected to be about 33.8%.”
• To optimize our investments in response to the current market conditions, we have reduced our Net Capex plan, now slightly below $2 billion for FY25.”
• “Our strategic priorities remain clear: accelerating innovation; executing our company-wide program to reshape our manufacturing footprint and resize our global cost base, which remains on schedule to deliver the targeted savings; and strengthening free cash flow generation.”

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 Income 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)	Sep 27 2025	Jun 28 2025	Mar 29 2025	Dec 31 2024	Sep 28 2024
Cash and cash equivalents	1,999	1,616	1,781	2,282	3,077
Short term deposits	1,450	1,650	1,650	1,450	977
Marketable securities	1,327	2,363	2,528	2,452	2,242

Total financial debt	(2,166)	(2,957)	(2,877)	(2,953)	(3,115)
Net Financial Position (non-U.S. GAAP)	2,610	2,672	3,082	3,231	3,181
Advances received on capital grants	(345)	(361)	(377)	(385)	(366)
Adjusted Net Financial Position (non-U.S. GAAP)	2,265	2,311	2,705	2,846	2,815

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)	Q3 2025	Q2 2025	Q1 2025	Q4 2024	Q3 2024
Payment for purchase of tangible assets, as reported	(431)	(574)	(587)	(584)	(669)
Proceeds from sale of tangible assets, as reported	3	4	2	-	2
Proceeds from capital grants and other contributions, as reported	11	89	47	83	66
Advances from capital grants allocated to property, plant and equipment	16	16	8	31	36
Net Capex (non-U.S. GAAP)	(401)	(465)	(530)	(470)	(565)

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.
 

(US$ m)	Q3 2025	Q2 2025	Q1 2025	Q4 2024	Q3 2024
Net cash from operating activities	549	354	574	681	723
