Geneva, July 26, 2017 - STMicroelectronics (NYSE: STM), a global semiconductor leader serving customers across the spectrum of electronics applications, reported financial results for the second quarter and first half ended July 1, 2017.

Second quarter net revenues totaled $1.92 billion, gross margin was 38.3%, and net income was $151 million, or $0.17 per share.

"It was another solid quarter, with both net revenues and gross margin sequentially performing better than seasonality and above the mid-point of our guidance," commented Carlo Bozotti, STMicroelectronics President and CEO.

"On a year-over-year basis, revenue growth came from all product groups and sales channels. In Internet of Things and smartphones, we continue to win with our complete portfolio of microcontrollers, sensors, analog and power management, connectivity and security solutions. In Smart Driving, we continue to capture opportunities both with products developed in our Automotive and Discrete Group, as well as from the rest of our organization which fit the needs of our automotive customers, such as sensors and general purpose analog.

"On top of our sales initiatives, during the quarter we improved our profitability thanks to our operating leverage, better product mix and manufacturing efficiencies driving our operating margin before impairment and restructuring to 9.6% in the second quarter.

"To strengthen our capital structure and further enhance our financial flexibility, in July we raised $1.5 billion at an overall zero cost, through a convertible bond offering. Additionally, the combination of the net share settlement option and the on-going repurchase of the underlying shares implies substantially no dilution at conversion to shareholders."

Impairment and restructuring charges in the second quarter were $6 million compared to $5 million and $12 million in the prior and year-ago quarter, respectively, mainly related to the set-top box restructuring plan announced in January 2016. The Company continued to make progress on its restructuring of the set-top box business. Exiting the second quarter of 2017, the restructuring plan was on track and had achieved a run-rate of about $132 million of the total $170 million of targeted annualized savings expected upon completion.

Operating income of $178 million in the second quarter increased by $49 million and $150 million compared to the prior and year-ago quarter, respectively.

Second quarter operating income before impairment and restructuring charges⁽¹⁾ was $184 million, equivalent to 9.6% of net revenues and expanded gross margin, increasing from $134 million, or 7.4% of net revenues in the previous quarter mainly due to higher revenues. On a year-over-year basis, operating income before impairment and restructuring charges⁽¹⁾ improved by $144 million reflecting higher revenues, improved product mix, manufacturing efficiencies and better fab loading.

Second quarter net income was $151 million, equivalent to $0.17 per share, compared to a net income of $108 million, equivalent to $0.12 per share, in the prior quarter.

Other income and expenses, net, registered income of $32 million compared to $55 million in the year-ago period mainly due to lower R&D funding.

First half impairment and restructuring charges were $11 million compared to $40 million in the year-ago period.

Operating income in the first half of 2017 improved significantly by $312 million to $307 million compared to the prior period.

First half 2017 operating income before impairment and restructuring charges⁽¹⁾ increased sharply to $318 million, compared to $35 million in the first half 2016. MDG operating income had a positive swing of $126 million, resulting in an increase in its operating margin to 10.9% for the 2017 first half with a higher margin for microcontrollers and memories and substantially reduced losses in the Company's digital businesses. AMG operating performance substantially improved with a positive swing in operating income of $112 million and expansion of its operating margin to 12.4% from essentially breakeven, with improvements coming from both MEMS and Analog. ADG operating income was up slightly from the 2016 first half and the operating margin was substantially stable at 7.1% compared to 7.2% in the year-ago period.

First half of 2017 net income, as reported, was $258 million, equivalent to $0.28 per share, compared to a net loss of $18 million, or negative $0.02 per share, in the first half of 2016.

Cash Flow and Balance Sheet Highlights

Capital expenditure payments, net of proceeds from sales, were $307 million and $526 million during the second quarter and first half of 2017, respectively. First half 2016 capital expenditures, net of proceeds from sales, were $236 million.

Inventory was $1.26 billion at quarter end, up 5% from the prior quarter. Inventory in the second quarter of 2017 was at 3.8 turns or 95 days.

The Company paid cash dividends totaling $48 million and $101 million for the second quarter and first half of 2017, respectively.

ST's net financial position⁽¹⁾ was $524 million at July 1, 2017 compared to $518 million at April 1, 2017. ST's total financial resources equaled $1.99 billion and total financial debt was $1.47 billion at July 1, 2017.

Total equity, including non-controlling interest, was $4.90 billion at July 1, 2017.

On June 22, 2017, ST launched and priced a $1.5 billion offering of senior unsecured bonds convertible into new or existing ordinary shares of ST. The Company simultaneously launched a share buy-back program of up to 19 million shares for an amount up to $297 million intended to meet its obligations arising from debt financial instruments that are exchangeable into equity instruments and to meet obligations arising from employee share award programs.

The terms of the New Convertible Bonds contain customary provisions which will allow the Company to satisfy conversion rights on the New Convertible Bonds with a combination of cash, new Shares and treasury Shares, or cash or Shares only including, unless the Company elects otherwise, by way of net share settlement. A net share settlement is the default settlement scenario under the New Convertible Bonds, and the Company's share buy-back program is designed to equal or exceed the number of Shares required to be delivered on the exercise of conversion rights under the New Convertible Bonds, assuming a net share settlement.

The Bonds were issued in two $750 million tranches, one with a maturity of 5 years (37.5% conversion premium, negative 0.25 yield to maturity, 0% coupon) and the other 7 years (37.5% conversion premium, 0.25 yield to maturity, 0.25% coupon). Under the terms of the Bonds, the Company can satisfy the conversion rights either in cash or shares, or a combination of the two, at its selection. Proceeds from the issuance of the Bonds will be used by STMicroelectronics for general corporate purposes, including support for growth, the early redemption of the outstanding $600 million convertible bond due 2019 which will be completed by the end of August and the future redemption of the outstanding $400 million convertible bond due 2021. The issuance of the new Bonds occurred on July 3, 2017, therefore the impact to financial reporting will be effective in the third quarter of 2017.

Third Quarter 2017 Business Outlook

Mr. Bozotti commented, "Based on current booking activity and visibility on our anticipated key new program, we expect third quarter revenues to increase about 9.0% on a sequential basis, representing year-over-year growth of about 16.6% at the mid-point of our guidance range. We anticipate another quarter of margin expansion with third quarter gross margin of about 39.0% at the mid-point, leading to strong year-over-year improvement in operating and net income.

"Overall, we believe we are very well positioned to reach the short-term financial targets we outlined for the second half of 2017 at our Capital Markets Day held in May."

The Company expects third quarter 2017 revenues to increase about 9.0% on a sequential basis, plus or minus 3.5 percentage points. Gross margin in the third quarter is expected to be about 39.0% plus or minus 2.0 percentage points.

This outlook is based on an assumed effective currency exchange rate of approximately $1.12 = ?,?1.00 for the 2017 third quarter and includes the impact of existing hedging contracts. The third quarter will close on September 30, 2017.

Supplemental Non-U.S. GAAP Financial Information
U. S. GAAP - Non-U.S. GAAP Reconciliation
In US$ Million Except Per Share Data ($)

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.

Operating income (loss) 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 closure 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 closure costs attributable to ST and other one-time items, net of the relevant tax impact.

The Company believes that these non-GAAP financial measures provide useful information for investors and management because they measure the Company's capacity to generate profits from its business operations, excluding the effect of acquisitions and expenses related to the rationalizing of its activities and sites that it does not consider to be part of its on-going operating results, thereby offering, when read in conjunction with the Company's GAAP financials, (i) the ability to make more meaningful period-to-period comparisons of the Company's on-going operating results, (ii) the ability to better identify trends in the Company's business and perform related trend analysis, and (iii) an easier way to compare the Company's results of operations against investor and analyst financial models and valuations, which usually exclude these items.

(continued)
(Appendix - continued)

Net financial position: resources (debt), represents the balance between our total financial resources and our total financial debt. Our total financial resources include cash and cash equivalents, marketable securities, short-term deposits and restricted cash, and our total financial debt includes short-term borrowings, current portion of long-term debt and long-term debt, all as reported in our consolidated balance sheet. We believe our net financial position provides useful information for investors and management because it gives evidence of our global position either in terms of net indebtedness or net cash position by measuring our capital resources based on cash, cash equivalents and marketable securities and the total level of our financial indebtedness. Net financial position is not a U.S. GAAP measure.

Free cash flow is defined as net cash from operating activities minus net cash from (used in) investing activities, excluding payment for purchases (proceeds from the sale of) marketable securities and short-term deposits, restricted cash and net cash variation for joint ventures deconsolidation. We believe 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 operating activities. Free cash flow is not a U.S. GAAP measure and does not represent total cash flow since it does not include the cash flows generated by or used in financing activities. In addition, our definition of free cash flow may differ from definitions used by other companies.
