Geneva, January 30, 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 fourth quarter ended December 31, 2024. This press release also contains non-U.S. GAAP measures (see Appendix for additional information).

ST reported fourth quarter net revenues of $3.32 billion, gross margin of 37.7%, operating margin of 11.1%, and net income of $341 million or $0.37 diluted earnings per share.

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

"FY24 revenues decreased 23.2% to $13.27 billion. Operating margin was 12.6% compared to 26.7% in FY23 and net income decreased 63.0% to $1.56 billion. We invested $2.53 billion in Net Capex (non-U.S. GAAP) while delivering free cash flow (non-U.S. GAAP) of $288 million."
"Q4 net revenues were in line with the mid-point of our business outlook range driven by higher revenues in Personal Electronics offset by lower revenues in Industrial, while Automotive and CECP were as expected. Q4 gross margin of 37.7% was broadly in line with the mid-point of our business outlook range."
"Our book-to-bill ratio remained below 1 in Q4 as we continued to face a delayed recovery and inventory correction in Industrial and a slowdown in Automotive, both particularly in Europe."
"Our first quarter business outlook, at the mid-point, is for net revenues of $2.51 billion, decreasing year-over-year by 27.6% and decreasing sequentially by 24.4%; gross margin is expected to be about 33.8%, impacted by about 500 basis points of unused capacity charges."
"For 2025, we plan to invest between $2.0 to $2.3 billion in Net Capex (non-U.S. GAAP)."

Cash Flow and Balance Sheet Highlights

				Trailing 12 Months
(US$ m)	Q4 2024	Q3 2024	Q4 2023	Q4 2024	Q4 2023	TTM Change
Net cash from operating activities	681	723	1,480	2,965	5,992	-50.5%
Free cash flow (non-U.S. GAAP)²	128	136	652	288	1,774	-83.8%

Net cash from operating activities was $681 million in the fourth quarter compared to $1.48 billion in the year-ago quarter. For the full-year 2024, net cash from operating activities decreased 50.5% to $2.97 billion, which represents 22.3% of total revenues.

Net Capex (non-U.S. GAAP), were $470 million in the fourth quarter and $2.53 billion for the full year 2024. In the respective year-ago periods, net capital expenditures were $798 million and $4.11 billion.

Free cash flow (non-U.S. GAAP) was $128 million and $288 million in the fourth quarter and full year 2024, respectively, compared to $652 million and $1.77 billion in the year-ago respective periods.

Inventory at the end of the fourth quarter was $2.79 billion, compared to $2.88 billion in the previous quarter and $2.70 billion in the year-ago quarter. Days sales of inventory at quarter-end was 122 days, compared to 130 days in the previous quarter, and 104 days in the year-ago quarter.

In the fourth quarter, ST paid cash dividends to its stockholders totaling $88 million and executed a $92 million share buy-back, as part of its current share repurchase program.

ST's net financial position (non-U.S. GAAP) was $3.23 billion as of December 31, 2024, compared to $3.18 billion as of September 28, 2024 and reflected total liquidity of $6.18 billion and total financial debt of $2.95 billion. Adjusted net financial position (non-U.S. GAAP), taking into consideration the effect on total liquidity of advances from capital grants for which capital expenditures have not been incurred yet, stood at $2.85 billion as of December 31, 2024.

Corporate developments

In Q4, we announced the launch of a new company-wide program to reshape our manufacturing footprint accelerating our wafer fab capacity to 300mm Silicon (Agrate and Crolles) and 200mm Silicon Carbide (Catania) and resizing our global cost base.

This program should result in strengthening our capability to grow our revenues with an improved operating efficiency resulting in annual cost savings in the high triple-digit million-dollar range exiting 2027. Specifically in terms of operating expenses (SG&A and R&D), ST expects annual cost savings totaling $300 to 360 million, exiting 2027, compared to the cost base of 2024.

Business Outlook

ST's guidance, at the mid-point, for the 2025 first quarter is:

Net revenues are expected to be $2.51 billion, a decrease of 24.4% sequentially, plus or minus 350 basis points.
Gross margin of 33.8%, plus or minus 200 basis points.
This outlook is based on an assumed effective currency exchange rate of approximately $1.06 = €1.00 for the 2025 first quarter and includes the impact of existing hedging contracts.
The first quarter will close on March 29, 2025.

Conference Call and Webcast Information

ST will conduct a conference call with analysts, investors and reporters to discuss its fourth quarter and full year 2024 financial results and current business outlook today at 9:30 a.m. Central European Time (CET) / 3:30 a.m. U.S. Eastern Time (ET).

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.

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. Starting Q4 2023, 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. Reporting periods prior to Q4 2023 are not impacted.

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 2024	Q3 2024	Q2 2024	Q1 2024	Q4 2023	FY 2024	FY 2023
Payment for purchase of tangible assets, as reported	(584)	(669)	(690)	(1,145)	(1,076)	(3,088)	(4,439)
Proceeds from sale of tangible assets, as reported	-	2	1	2	-	5	8
Proceeds from capital grants and other contributions, as reported	83	66	143	149	278	441	320
Advances from capital grants allocated to property, plant and equipment	31	36	18	27	-	111	-
Net Capex	(470)	(565)	(528)	(967)	(798)	(2,531)	(4,111)

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 2024	Q3 2024	Q2 2024	Q1 2024	Q4 2023	FY 2024	FY 2023
