• Q326 net revenues at $3.76 billion
• Gross margin at 37.3%
• Operating income at $367 million (non-U.S. GAAP¹ operating income at $429 million)
• Business outlook at mid-point: Q426 net revenues of $4.15 billion and gross margin of 39.0%

Geneva, October 29, 2026 – 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 26, 2026. This press release also contains non-U.S. GAAP measures (see Appendix for additional information).

ST reported third quarter net revenues of $3.76 billion, gross margin of 37.3%, operating income of $367 million, and net income of $291 million or $0.31 diluted earnings per share (non-U.S. GAAP¹ operating income of $429 million, and non-U.S. GAAP¹ net income of $344 million or $0.37 diluted earnings per share).

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

• “Q3 net revenues came above the mid-point of our business outlook range, driven by higher revenues in CECP and Personal Electronics. Gross margin was above the mid-point of our business outlook range.”
• “On a year-over-year basis, Q3 net revenues increased 17.9%. Q3 gross margin was 37.3%, operating margin was 9.8% and net income was $291 million. On a non-U.S. GAAP¹ basis operating margin was 11.4% and net income was $344 million.”
• “During the quarter, demand increased further supported by strong bookings and improving visibility, while inventory in distribution continued to track below our standard target. Together, these indicators confirm the continued ongoing recovery and secular growth across the markets we serve.”
• “Our fourth quarter business outlook, at the mid-point, is for net revenues of $4.15 billion, increasing about 10.5% sequentially and about 24.7% year-over-year. Gross margin is expected to be about 39.0%, including about 40 basis points of unused capacity charges.”
• “The mid-point of this outlook translates into full year 2026 revenues of about $14.5 billion, representing a 22.8% year-over-year increase. Beyond the cyclical recovery across our end markets, the year-over-year growth is supported by ST's company specific growth drivers, including AI datacenters and LEO satellite communication. Gross margin is expected to be about 36.4%, non-U.S. GAAP¹ gross margin is expected to be about 36.6%, representing an improvement of 270 basis points versus FY25.”
• “In an environment where demand remains well above supply, we continue to expand capacity aligned with ST’s strategic roadmap. We remain focused on improving profitability consistent with our intermediate financial model. This is driven by our company-specific growth drivers and the execution of our company-wide program to reshape our manufacturing footprint and resize our global cost base.”

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

Operating income before impairment, restructuring charges and other related phase-out costs, and other certain 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, and PPA effects. Non-U.S. GAAP gross profit is also used by management to communicate the impact of PPA effects on gross margin. 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 and other certain items, such as PPA effects, net of the relevant tax impact.

Q3 2026 (US$ m, except per share data)	Gross Profit	Operating Income	Net Income	Corresponding Diluted EPS
U.S. GAAP	1,401	367	291	0.31
Impairment, restructuring charges and other related phase-out costs	-	55	55

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 26 2026	Jun 27 2026	Mar 28 2026	Dec 31 2025	Sep 27 2025
Cash and cash equivalents	2,612	3,096	1,889	2,837	1,999
Short term deposits	1,400	1,800	1,850	1,100	1,450
Marketable securities	1,300	1,136	832	985	1,327
Total liquidity	5,312	6,032	4,571	4,922	4,776
Short-term debt	(309)(b)	(1,063)(b)	(319)	(298)	(256)
Long-term debt (a)	(2,897)	(2,962)	(2,250)	(1,835)	(1,910)
Total financial debt	(3,206)	(4,025)	(2,569)	(2,133)	(2,166)
Net Financial Position (non-U.S. GAAP)	2,106	2,007	2,002	2,789	2,610
Advances received on capital grants	(300)	(306)	(316)	(333)	(345)
Adjusted Net Financial Position (non-U.S. GAAP)	1,806	1,701	1,686	2,456	2,265

^(a)  Long-term debt contains standard conditions but does not impose minimum financial ratios. Committed credit facilities for $1,198 million equivalent are currently undrawn.
^(b)  During Q326 ST net settled its convertible bond due 2027 delivering $750 million in cash and about 4.2 million shares from treasury stock. Q226 short-term debt includes $750 million after the announcement of the early redemption of the convertible bonds due 2027.

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, and therefore, comparability may be limited.

(US$ m)	Q3 2026	Q2 2026	Q1 2026	Q4 2025	Q3 2025
Payment for purchase of tangible assets, as reported	(683)	(453)	(549)	(518)	(431)
Proceeds from capital grants and other contributions, as reported	31	34	167	111	11
Advances from capital grants allocated to property, plant and equipment	6	10	17	12	16
Proceeds from sale of tangible assets, as reported	3	-	3	-	3
Net Capex (non-U.S. GAAP)	(643)	(409)	(362)	(395)	(401)

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, and therefore, comparability may be limited.

(US$ m)	Q3 2026	Q2 2026	Q1 2026	Q4 2025	Q3 2025
Net cash from operating activities	1,020	502	534	674	549
