Market Reality Check
Peers on Argus
STM gained 3.3% while key semiconductor peers showed mixed, mostly modest moves: ASX +0.55%, ON +0.23%, MCHP +0.58%, but GFS -4.41% and UMC -0.65%, suggesting a company-specific reaction to its earnings rather than a broad sector rotation.
Previous Earnings Reports
| Date | Event | Sentiment | Move | Catalyst |
|---|---|---|---|---|
| Oct 23 | Q3 2025 earnings | Negative | -13.3% | Revenue down year-over-year, margin contraction, and added impairment charges. |
| Jul 24 | Q2 2025 earnings | Negative | -4.9% | Double-digit revenue drop, operating loss and net loss with heavy charges. |
| Apr 24 | Q1 2025 earnings | Negative | +4.4% | Sharp revenue and income declines but guidance indicated sequential improvement. |
| Jan 30 | Q4 2024 earnings | Negative | -9.0% | Revenues and margins down markedly for both quarter and full year 2024. |
| Oct 31 | Q3 2024 earnings | Negative | -1.5% | Strong year-over-year revenue decline and cautious outlook into Q4–Q1. |
Recent earnings reports have generally highlighted revenue declines and margin pressure, with the stock usually trading lower on these updates; only Q1 2025 saw a positive reaction despite weak metrics.
Over the last five earnings cycles, STMicroelectronics has reported declining year-over-year revenues and compressing margins, alongside restructuring and impairment charges to reshape its manufacturing footprint. Q2 and Q3 2025 showed losses or sharply reduced profitability, while Q4 2024 and earlier still had double‑digit margins. Today’s Q4/FY 2025 results mark a return to modest year-over-year quarterly revenue growth, with continued elevated charges and cautious, sequentially lower Q1 2026 guidance.
Historical Comparison
In the past five earnings releases, STM’s average move was about 6.61%. Today’s 3.3% move on Q4/FY 2025 results sits below that typical earnings reaction magnitude.
Earnings releases from late <b>2024</b> through <b>2025</b> show a progression from steep revenue declines and double‑digit margins to a weaker profitability profile with restructuring and impairment charges, followed by Q4 <b>2025</b> stabilizing revenues and guiding for continued sequential softening but improving year-over-year dynamics.
Market Pulse Summary
This announcement details Q4 2025 net revenues of $3.33 billion and a gross margin of 35.2%, including significant impairment and restructuring costs that led to a quarterly net loss. For FY 2025, revenues fell to $11.80 billion with a 1.5% operating margin, while net cash from operations reached $2.15 billion. Investors may track execution on manufacturing footprint reshaping, planned $2.0–2.2 billion 2026 Net Capex, and whether guidance-driven growth restores margins and free cash flow.

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.

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, restructuring charges and other related phase-out costs, 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.

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) | Q4 2025 | Q3 2025 | Q2 2025 | Q1 2025 | Q4 2024 |
| Payment for purchase of tangible assets, as reported | (518) | (431) | (574) | (587) | (584) |
| Proceeds from sale of tangible assets, as reported | - | 3 | 4 | 2 | - |
| Proceeds from capital grants and other contributions, as reported | 111 | 11 | 89 | 47 | 83 |
| Advances from capital grants allocated to property, plant and equipment | 12 | 16 | 16 | 8 | 31 |
| Net Capex (non-U.S. GAAP) | (395) | (401) | (465) | (530) | (470) |
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) | Q4 2025 | Q3 2025 | Q2 2025 | Q1 2025 | Q4 2024 |
| Net cash from operating activities | 674 | 549 | 354 | 574 | 681 |
