Geneva, April 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 first quarter ended

March 28, 2026. This press release also contains non-U.S. GAAP measures (see Appendix for additional information).

ST reported first quarter net revenues of $3.10 billion, gross margin of 33.8%, operating income of $70 million, and net

income of $37 million or $0.04 diluted earnings per share (non-U.S. GAAP1 gross margin of 34.1%, non-U.S. GAAP1

operating income of $171 million, and non-U.S. GAAP1 net income of $122 million or $0.13 diluted earnings per share).

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

•“Q1 net revenues, excluding the contribution of our acquisition of NXP’s MEMS sensor business, came above

the mid-point of our business outlook range, driven mainly by higher revenues in our engaged customer

programs in Personal electronics and CECP. Gross margin was above the mid-point of our business outlook

range mainly due to better product mix.”

•“On a year-over-year basis, Q1 net revenues increased 23.0%; excluding the contribution of our acquisition of

NXP’s MEMS sensor business, they increased 21.4%. Q1 gross margin was 33.8%, operating margin was

2.3% and net income was $37 million. On a non-U.S. GAAP1 basis gross margin was 34.1%, operating margin

was 5.5% and net income was $122 million.”

•“In Q1, despite the macroeconomic uncertainty, we saw improving demand with strong booking and

normalized inventory in distribution.”

•“Our second quarter business outlook, at the mid-point, is for net revenues of $3.45 billion, increasing 11.6%

sequentially and 24.9% year-over-year. Gross margin is expected to be about 34.8%, including about 100

basis points of unused capacity charges. Non-U.S. GAAP1 gross margin is expected to be about 35.2%.”

•“ST is now strategically positioned to capture upside from new AI driven programs, leveraging specialized

technologies to enable the evolving AI infrastructure, confirming our datacenters revenue expectation to be

nicely above $500 million for 2026 and well above $1 billion for 2027.”

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 Purchase Price

Allocation (PPA) effects. 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 Purchase Price Allocation (PPA)

effects, 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.

Adjusted Net Financial Position (non-U.S. GAAP)	1,686	2,456	2,265	2,311	2,705

(a)Total liquidity decreased from $4.92 billion in the fourth quarter of 2025 to $4.57 billion in the first quarter of 2026, after the cash-out of $895 million

related to the acquisition of NXP MEMS sensor business. Total liquidity decreased from $5.63 billion in the second quarter of 2025 to $4.78 billion

in the third quarter of 2025, the decrease includes $750 million related to the repayment of the first tranche of our convertible bond.

(b)Long-term debt contains standard conditions but does not impose minimum financial ratios. Committed credit facilities for $1,210 million equivalent

are currently undrawn. As of March 28, 2026, total financial debt included $590 million long-term debt following the withdrawal of the €500 million

first tranche of the new EIB credit line.

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<br><br>2026	Q4<br><br>2025	Q3<br><br>2025	Q2<br><br>2025	Q1<br><br>2025

Net Capex (non-U.S. GAAP)	(362)	(395)	(401)	(465)	(530)

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.
