STMicroelectronics Reports Q2 2026 Financial Results

Q226 net revenues at $3.49 billion
Gross margin at 34.8% (non-U.S. GAAP¹ gross margin at 35.2%)
Operating income at $187 million (non-U.S. GAAP¹ operating income at $269 million)
Business outlook at mid-point: Q326 net revenues of $3.70 billion and gross margin of 37.0%

Geneva, July 23, 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 second quarter ended June 27, 2026. This press release also contains non-U.S. GAAP measures (see Appendix for additional information).

ST reported second quarter net revenues of $3.49 billion, gross margin of 34.8%, operating income of $187 million, and net income of $222 million or $0.24 diluted earnings per share (non-U.S. GAAP¹ gross margin of 35.2%, non-U.S. GAAP¹ operating income of $269 million, and non-U.S. GAAP¹ net income of $291 million or $0.31 diluted earnings per share).

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

"Q2 net revenues came above the mid-point of our business outlook range, driven by higher revenues in CECP and Automotive. Gross margin was in line with the mid-point of our business outlook range."
"On a year-over-year basis, Q2 net revenues increased 26.0%. Q2 gross margin was 34.8%, operating margin was 5.4% and net income was $222 million. On a non-U.S. GAAP¹ basis gross margin was 35.2%, operating margin was 7.7% and net income was $291 million."
"During the quarter demand increased further, with strong bookings in all end markets. We saw improved visibility and signs of tight supply in several product categories. Inventory in distribution is now below our standard target."
"Our third quarter business outlook, at the mid-point, is for net revenues of $3.70 billion, increasing about 6.2% sequentially and about 16.2% year-over-year. Gross margin is expected to be about 37.0%, including about 70 basis points of unused capacity charges."
"We anticipate a revenue growth acceleration in Q4, mainly driven by our engaged customer programs in AI datacenters and LEO satellite communication. We expect Q4 revenues to be above $4 billion, this translates into a H2 vs H1 growth above our normal 15% seasonality."
"Driven by continued strong demand in AI datacenters, we are raising our revenue ambition for datacenters. Revenues are now expected above $1 billion in 2026 and, assuming the current dynamic continues and with the current engagements we have, well above $2 billion in 2027. This confirms ST’s strong position in the evolving AI datacenters."

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.

Q2 2026 (US$ m, except per share data)	Gross Profit	Operating Income	Net Income	Corresponding Diluted EPS

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)	Jun 27 2026	Mar 28 2026	Dec 31 2025	Sep 27 2025	Jun 28 2025
Cash and cash equivalents	3,096	1,889	2,837	1,999	1,616

^(a)Total liquidity and long-term debt increased following the issuance of a new $1.5 billion dual-tranche senior unsecured convertible bonds.

^(b)Long-term debt contains standard conditions but does not impose minimum financial ratios. Committed credit facilities for $1,191 million equivalent are currently undrawn. 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.

Net Capex (non-U.S. GAAP)	(409)	(362)	(395)	(401)	(465)

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.
