Insights

Semiconductor Industry Analyst

STMicroelectronics reports severe 99.5% operating income collapse with weak margins; restructuring underway amid semiconductor downturn.

STMicroelectronics' Q1 2025 results reveal a semiconductor company in the midst of a severe downturn. Revenue plummeted 27.3% year-over-year to $2.52 billion, while operating income collapsed an alarming 99.5% to just $3 million from $551 million a year earlier. The gross margin contracted to 33.4% from 41.7% last year, primarily due to unfavorable product mix and higher unused capacity charges.

The depth of STM's challenges is evident across all segments. Particularly concerning is the Power and Discrete segment, which swung from a $77 million profit to a $28 million loss with margins deteriorating from positive 12.1% to negative 6.9%. Even the traditionally resilient Embedded Processing segment saw operating profit plunge 71.5%.

Inventory metrics signal ongoing demand weakness, with days sales of inventory ballooning to 167 days from 122 days a year ago. This inventory build-up represents a significant cash conversion challenge that could persist for multiple quarters.

While management views Q1 as the cyclical bottom, the recovery trajectory appears gradual. Q2 guidance projects a 7.7% sequential improvement but still represents a substantial 16.2% year-over-year decline. The improved book-to-bill ratio in Automotive and Industrial segments suggests early signs of stabilization, but the semiconductor downcycle appears deeper and more prolonged than typical industry contractions.

One bright spot remains STM's financial position, with $5.96 billion in total liquidity and positive free cash flow of $30 million, providing flexibility to navigate the downturn while continuing strategic investments.

Manufacturing Operations Expert

STM implements major manufacturing restructuring amid 99.5% operating income drop; targets high triple-digit million savings by 2027.

STMicroelectronics' manufacturing operations are undergoing significant transformation amid severe financial pressure. The company has initiated a comprehensive program to reshape its global manufacturing footprint and resize its cost base, targeting annual cost savings in the high triple-digit million-dollar range by the end of 2027. This indicates a substantial structural overhaul rather than merely temporary cost-cutting measures.

The operational challenges are evident in the company's 33.4% gross margin, which missed guidance by 40 basis points and includes approximately 420 basis points of unused capacity charges projected for Q2. This significant drag on profitability reflects substantial manufacturing overcapacity relative to current demand levels.

Despite the downturn, STM is maintaining its capital expenditure plan between $2.0-2.3 billion for 2025, primarily directed toward executing the manufacturing footprint restructuring. This suggests the company is simultaneously consolidating certain operations while potentially expanding in strategic areas, rather than simply reducing overall capacity.

Inventory management has become a critical challenge, with inventory levels rising to $3.01 billion from $2.69 billion a year ago. The dramatic increase in days sales of inventory to 167 days (from 122) indicates production rates have not been sufficiently adjusted to match the demand slowdown.

While management has not detailed specific facility changes, the scale of projected savings suggests potential facility closures, production line consolidations, and workforce reductions. The multi-year implementation timeline reflects the complexity of reorganizing semiconductor manufacturing operations while maintaining business continuity and customer commitments.

ST reported first quarter net revenues of $2.52 billion, gross margin of 33.4%, operating income of $3 million and net income of $56 million or $0.06 diluted earnings per share.

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

• “Q1 net revenues came in line with the midpoint of our business outlook range, driven by higher revenues in Personal Electronics offset by lower-than-expected revenues in Automotive and Industrial. Gross margin was slightly below the mid-point of our business outlook range mainly due to product mix.”
• “On a year-over-year basis, Q1 net revenues decreased 27.3%, operating margin decreased to 0.1% from 15.9% and net income decreased 89.1% to $56 million.”
• “In the first quarter, our book-to-bill ratio improved with both Automotive and Industrial above parity.”
• “Our second quarter business outlook, at the mid-point, is for net revenues of $2.71 billion, decreasing year-over-year by 16.2% and increasing sequentially by 7.7%; gross margin is expected to be about 33.4%, impacted by about 420 basis points of unused capacity charges.”
• “We plan to maintain our Net Capex (non-U.S. GAAP¹) plan for 2025 between $2.0 billion and $2.3 billion mainly to execute the reshaping of our manufacturing footprint.”
• “While we see Q1 2025 as the bottom, in the current uncertain environment we are focusing on what we can control: keep on innovating to continuously improve and accelerate the competitiveness of our product and technology portfolio, focus on advanced manufacturing and tightly manage our costs. In this respect our company-wide program to reshape ST manufacturing footprint and resize our global cost base is on track and we confirm the annual cost savings target in the high triple-digit million-dollar range exiting 2027.”

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:

ST 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 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)	Mar 29 2025	Dec 31 2024	Sep 28 2024	June 29 2024	Mar 30 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)	Q1 2025	Q4 2024	Q3 2024	Q2 2024	Q1 2024
Payment for purchase of tangible assets, as reported	(587)	(584)	(669)	(690)	(1,145)

Proceeds from capital grants and other contributions, as reported	47	83	66	143	149

Net Capex (non-U.S. GAAP)	(530)	(470)	(565)	(528)	(967)

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)	Q1 2025	Q4 2024	Q3 2024	Q2 2024	Q1 2024
