OVERVIEW

Our key priorities for 2008 remain unchanged from the previous four years:
protect our financial health, improve our profitability, and invest in the future. During the second quarter of 2008, we made the following progress against these priorities:

Financial Health

Our balance sheet remains strong, and we generated significant positive cash flows from operating activities.

• Our debt to capital ratio of 10% at June 30, 2008 remains low, reflecting an improvement from 14% at December 31, 2007.

• Operating cash flow in the first half of 2008 was $985 million.

• We ended the second quarter of 2008 with $3.5 billion of cash and short-term investments.

Profitability

For the three months ended June 30, 2008, we generated net income of $3.2 billion or $2.01 per share compared to net income of $489 million or $0.30 per share for the same period in 2007. When compared to the same period last year, the improvement in net income was due largely to the following items:

• The release of $2.4 billion of valuation allowances. In the second quarter, we concluded that it is more likely than not that we will realize substantially all of our U.S. deferred tax assets because we expect to generate sufficient levels of income in the U.S. As a result, we released $2.4 billion of valuation allowances on our U.S. deferred tax assets. For additional information, refer to Note 6 (Income Taxes) to the consolidated financial statements.

• Higher net income in the Display Technologies segment driven by very strong sales volumes, an increase in equity earnings from Samsung Corning Precision, strong manufacturing performance, and the strength of the Japanese yen - U.S. dollar exchange rate. Our manufacturing facilities continue to operate at or near capacity reflecting continuing strong demand for liquid crystal display (LCD) glass substrates in spite of economic uncertainty.

For the six months ended June 30, 2008, we reported net income of $4.2 billion or $2.65 per share which represented an increase of $3.4 billion over the same period in 2007. The increase was primarily attributable to the valuation allowance release described above, higher net income in the Display Technologies segment, and a credit to asbestos settlement expense of $318 million reflecting the change in the estimate of our asbestos settlement liability compared to expense of $186 million for the same period last year. In the first quarter of 2008, Corning reduced its liability for asbestos litigation as a result of the increase in the likelihood of a settlement under recently proposed terms and a corresponding decrease in the likelihood of a settlement under terms established in 2003. For additional information on this matter, refer to Note 3 (Commitments and Contingencies) to the consolidated financial statements and Part II - Other Information, Item 1. Legal Proceedings.

Investing in Our Future

We continue to focus on the future and on what we do best - creating and making keystone components that enable high-technology systems. We remain committed to investing in research, development, and engineering to drive innovation and continue to work on technologies for glass substrates for active matrix LCD glass substrates, diesel filters and substrates in response to tightening emissions control standards, and the optical fiber and cable and hardware and equipment that enable fiber-to-the-premises.

Our research, development and engineering expenses for the three and six months ended June 30, 2008, increased by $26 million and $47 million, respectively, when compared to the same period last year but remained relatively constant as percentage of net sales. The largest driver of this increase was spending on development projects such as green lasers and microreactors and baseline research for new business development. We believe our spending levels are adequate to support our technology and innovation strategies.

Capital spending totaled $864 million and $466 million for the six months ended June 30, 2008 and 2007, respectively. We remain committed to investing in manufacturing capacity to match increased demand in our businesses. As a result, capital expenditures in 2008 are expected to be heavily focused on expanding manufacturing capacity for LCD glass substrates in the Display Technologies segment and diesel products in the Environmental Technologies segment.

We expect our 2008 capital spending to be in the range of $1.8 billion to $2.0 billion, which is approximately $300 million higher than the estimate provided in our 2007 Form 10-K. The increase is driven primarily by the acceleration of LCD capacity in anticipation of a stronger 2010 display market and growing demand for Corning's Gorilla™ glass, an optical quality glass that is optimized for high-end portable devices and touch screens. Higher precious metals prices are also contributing to the increased capital spending. We expect approximately $1.2 billion to $1.4 billion will be directed toward our Display Technologies segment to meet the continued increase in demand for LCD glass.

Net Sales

For the three and six months ended June 30, 2008, the net sales increase compared to the same periods in 2007 was primarily the result of year-over-year increased volumes in the Display Technologies segment and movements in foreign exchange rates. For the three and six months ended June 30, 2008, net sales were positively impacted by approximately $136 million and $255 million, respectively due to movements in foreign exchange rates, primarily the Japanese yen - U.S. dollar exchange rate because sales of the Display Technologies segment are denominated in Japanese yen.

Cost of Sales

The types of expenses included in the cost of sales line item are: raw materials consumption, including direct and indirect materials; salaries, wages and benefits; depreciation and amortization; production utilities; production-related purchasing; warehousing (including receiving and inspection); repairs and maintenance; inter-location inventory transfer costs; production and warehousing facility property insurance; rent for production facilities; and other production overhead.

Gross Margin

As a percentage of net sales, gross margin for the three and six months ended June 30, 2008, increased 4 and 5 percentage points, respectively, when compared to the same periods in 2007. The improvement in overall gross margin dollars for both periods presented was due primarily to volume gains and cost reduction in the Display Technologies segment.

Selling, General and Administrative Expenses

For the three and six months ended June 30, 2008, selling, general, and administrative expenses increased $31 million and $59 million, respectively, when compared to the same periods in 2007 due primarily to increased compensation-related costs and the impact of a $12 million litigation settlement in the second quarter of 2008. Selling, general, and administrative expenses as a percentage of sales decreased slightly for both periods presented when compared to the same periods last year.

The types of expenses included in the selling, general and administrative expenses line item are: salaries, wages and benefits; stock-based compensation expense; travel; sales commissions; professional fees; depreciation and amortization, utilities, and rent for administrative facilities.

Research, Development and Engineering Expenses

For the three and six months ended June 30, 2008, research, development and engineering expenses increased by $26 million and $47 million, respectively, when compared to the same period last year but remained even as a percentage of net sales. Expenditures are currently focused on our Display Technologies, Environmental Technologies and Telecommunications segments as we strive to capitalize on growth opportunities in those segments. The largest driver of this increase was spending on development projects such as green lasers and microreactors and baseline research for new business development.

Asbestos Settlement

In the second quarter of 2008 and 2007, we recorded an increase to our asbestos settlement liability of $9 million and $76 million, respectively. In the six months ended June 30, 2008 we recorded a net decrease to the asbestos settlement liability of $318 million compared to a charge of $186 million in the same period last year. The net decrease in the first half of 2008 was due to a $327 million reduction to our estimated liability for asbestos litigation that was recorded in the first quarter of 2008 as a result of the increase in the likelihood of a settlement under more recently proposed terms and a corresponding decrease in the likelihood of a settlement under terms that had been established in 2003. The charge of $9 million, recorded in the second quarter of 2008, reflected a change in the settlement value of the liability under the terms being negotiated.

For additional information on this matter, refer to Note 3 (Commitments and Contingencies) to the consolidated financial statements and Part II - Other Information, Item 1. Legal Proceedings.

Other Income, Net

"Other income, net" in Corning's consolidated statements of income includes
items such as royalty income, foreign exchange gains and losses, and
miscellaneous income and expense. Royalty income from Samsung Corning Precision
Glass Co., Ltd. (Samsung Corning Precision) represents the largest item included
in "Other income, net" in Corning's consolidated statements of income.
Significant amounts for the periods presented are as follows:

                                                        Three months          Six months
                                                       ended June 30,       ended June 30,
                                                       2008       2007       2008       2007

Royalty income from Samsung Corning Precision         $    50      $ 34    $     93      $ 63
Foreign currency exchange and hedge (losses) / gains       (6)       13         (34)       27
Gain on sale of Corning's submarine cabling business                 19                    19

In the second quarter of 2008, "Other income, net" declined when compared to the same period last year due to the absence of a $19 million gain on the sale of Corning's European submarine cabling business which was recorded in the second quarter of 2007 and the impact of foreign currency exchange transactions offset by an increase in royalty income from Samsung Corning Precision.

In the six months ended June 30, 2008, the decline in "Other income, net" resulted from an increase in royalty income from Samsung Corning Precision that was more than offset by the impact of foreign currency exchange and hedging transactions along with the absence of the gain on the sale of Corning's European submarine cabling business when compared to the same period last year.

Income Before Income Taxes

Income before income taxes for the three and six months ended June 30, 2008, was positively impacted by $71 million and $109 million, respectively, due to movements in foreign exchange rates compared to the first quarter of 2007.

Provision for Income Taxes

Our provision for income taxes and the related effective income tax rates were
as follows (in millions):

                                         Three months            Six months
                                        ended June 30,         ended June 30,
                                        2008        2007       2008        2007

Provision (benefit) for income taxes $ (2,388)     $ 19     $ (2,322)     $  75
Effective tax (benefit) rate            (515.8)%     6.6%      (185.3)%     16.4%

For the three months ended June 30, 2008, the effective income tax rate differed from the U.S. statutory rate of 35% primarily due to the following items:

• The release of $2.4 billion of valuation allowances resulting from a change in judgment about the realizability of deferred tax assets in future years, described below.

• The impact of not recording net tax expense on income generated in the U.S.

• The benefit of tax holidays and investment credits in foreign jurisdictions.

• The impact of discrete items for which no tax benefit was recorded, including litigation-related items totaling $21 million. Refer to Note 3 (Commitments and Contingencies) for additional information about asbestos settlement litigation. Discrete items and the valuation allowance release decreased our effective tax rate by 529.2 percentage points.

In addition to the items noted above, the tax provision for the six months ended June 30, 2008, reflected the impact of additional discrete items for which no tax expense was recorded including an asbestos settlement credit of $327 million. For the six months ended June 30, 2008, discrete items and the valuation allowance release decreased our effective tax rate by 199.2 percentage points.

For the three months ended June 30, 2007, the effective tax rate reflected the following items:

• The impact of not recording tax benefits (expenses) on losses (income) generated in the U.S. until management could determine that an appropriate level of profitability could be reached and sustained in the U.S.

• The benefit of tax holidays and investment credits in Taiwan.

• The release of a $17 million reserve related to a favorable tax ruling from the Taiwanese government received in the second quarter of 2007.

• The impact of discrete items for which no tax benefit was recorded including asbestos settlement expense of $76 million and a gain on the sale of our European submarine cabling business. Refer to Note 3 (Commitments and Contingencies) for additional information about the asbestos settlement. Discrete items and the tax reserve release decreased our effective tax rate by 5.4 percentage points for the three months ended June 30, 2007.

In addition to the items noted above, the tax provision for the six months ended June 30, 2007, reflected the impact of additional discrete items for which no tax benefit was recorded including asbestos settlement expense of $110 million and a loss on the repurchase of debt of $15 million. For the six months ended June 30, 2007, discrete items increased our effective tax rate by 1.9 percentage points.

As more fully described in Note 6 (Income Taxes) to the consolidated financial statements in our 2007 Form 10-K, all of our U.S. deferred tax assets had full valuation allowances at December 31, 2007. In the second quarter, we concluded that it is more likely than not that we will realize substantially all of our U.S. deferred tax assets because we expect to generate sufficient levels of income in the U.S. As a result, we released $2.4 billion of valuation allowances on our U.S. deferred tax assets. In accordance with SFAS 109, "Accounting for Income Taxes" (SFAS 109), we considered all available evidence, both positive and negative, to determine whether, based on the weight of that evidence, a valuation allowance is needed.

The evaluation of the realizability of deferred tax assets is inherently subjective. Following are the key items that provided positive evidence to support the release of the valuation allowance for a large portion of our deferred tax assets in the second quarter of 2008:

• Positive pre-tax income in the U.S. for the first half of 2008 and the preceding year.

• The impact of positive results in the Display Technologies operating segment and the royalty income generated from the foreign locations in this segment. A significant factor in our forecasts of future U.S. tax profitability is the amount of assumed royalties to be paid by our Display Technologies businesses to the U.S. At December 31, 2007, concerns about U.S. economic uncertainty led us to conclude that positive evidence supporting the realization of our U.S. deferred tax assets was not sufficient at that time. In spite of U.S. recessionary concerns, performance of our Display Technologies segment in 2008 has been very strong. Our manufacturing facilities in this segment have operated at or near capacity for the first half of 2008. We have also accelerated capital spending plans to increase capacity in anticipation of a stronger display market in future years.

• The number of years remaining to utilize our net operating loss carryforwards. Corning has approximately 16 years remaining to utilize the majority of our net operating loss carryforwards.

• Increased confidence in our forecasted income levels for the immediate year and future years which are supported by detailed sensitivity analyses. Our five-year planning process which is completed annually in the second quarter, considers a number of possible favorable and unfavorable scenarios which support the future realization of our U.S. deferred tax assets.

Certain shorter-lived deferred tax assets such as those represented by capital loss carry forwards and state tax net operating loss carry forwards as well as other federal and state tax credits will remain with a valuation allowance against them as of June 30, 2008, as it is not more likely than not that we will earn income of the character required to utilize these assets before they expire. The amount of valuation allowance that remains against these assets at June 30, 2008 was $234 million.

Refer to Note 5 (Income Taxes) to the consolidated financial statements for additional information.

Equity earnings for the second quarter of 2008 reflected earnings increases for Samsung Corning Precision and Dow Corning and the absence of restructuring and impairment charges from Samsung Corning when compared to the same period in 2007.

The increase in equity earnings for Samsung Corning Precision is explained in the discussion of the performance of our Display Technologies segment.

The increase in equity earnings from Dow Corning for the second quarter of 2008 when compared to the same period last year was due primarily to volume gains along with an increase in prices for certain silicone products. The decline in equity earnings from Dow Corning for the six months ended June 30, 2008, compared to the same period in 2007, was largely attributable to an increase in raw material prices offset somewhat by volume gains and price increases.

In the second quarter of 2007, equity earnings from Samsung Corning included $15 million for our share of restructuring and impairment charges. Until December 31, 2007, Corning had a 50% interest in Samsung Corning. Samsung Electronics Company, Ltd. and affiliates owned the remaining 50% interest in Samsung Corning. On December 31, 2007, Samsung Corning Precision acquired all of the outstanding shares of Samsung Corning. After the transaction, Corning retained its 50% interest in Samsung Corning Precision. Refer to Note 9 (Investments) to the consolidated financial statements for additional information relating to Samsung Corning Precision, Dow Corning, and Samsung Corning's operating results.

OPERATING SEGMENTS

Effective January 1, 2008, Corning changed its internal reporting structure to better reflect the company's focus on new business development and later-stage research projects and to provide more transparency on our Specialty Materials operating segment. As a result, our segment reporting includes the following changes which are in accordance with SFAS 131, "Disclosures about Segments of an Enterprise and Related Information:"

• We have provided separate financial information for the Specialty Materials operating segment. This operating segment was previously included in All Other.

• Certain later-stage development projects, such as microreactors and green lasers, now meet the criteria for operating segments and are included in All Other. Spending for these projects was previously part of Exploratory Research and was reported in the reconciliation of reportable segment net income to total net income.

• Certain other new product lines now meet the criteria for operating segments and are included in All Other. Spending related to these businesses was previously included in our Life Sciences and Display Technologies operating segments.

Our reportable operating segments are now as follows:

• Display Technologies - manufactures liquid crystal display glass for flat panel displays.

• Telecommunications - manufactures optical fiber and cable and hardware and equipment components for the telecommunications industry.

• Environmental Technologies - manufactures ceramic substrates and filters for automotive and diesel applications. This reportable operating segment is an aggregation of our Automotive and Diesel operating segments as these two segments share similar economic characteristics, products, customer types, production processes and distribution methods.

• Specialty Materials - manufactures products that provide more than 150 material formulations for glass, glass ceramics and fluoride crystals to meet demand for unique customer needs.

• Life Sciences - manufactures glass and plastic consumables for scientific applications.

All other operating segments that do not meet the quantitative threshold for separate reporting have been grouped as "All Other." This group is now primarily comprised of development projects and results for new product lines.

We prepared the financial results for our reportable segments on a basis that is consistent with the manner in which we internally disaggregate financial information to assist in making internal operating decisions. We included the earnings of equity affiliates that are closely associated with our operating segments in the respective segment's net income. We have allocated certain common expenses among segments differently than we would for stand-alone financial information prepared in accordance with GAAP. Segment net income may not be consistent with measures used by other companies. The accounting policies of our reportable segments are the same as those applied in the consolidated financial statements.

The increase in net sales for the second quarter of 2008 compared to the second quarter of 2007 reflects volume gains of 26% (measured in square feet of glass sold) as our manufacturing facilities continued to operate at or near capacity during the quarter and the positive impact of foreign exchange rate movement. Volume gains were offset somewhat by price declines of 8%. Year-over-year volume gains continue to be driven by increased TV market penetration, demand for large-size substrates (generation 5 and above), and continued strong demand for glass for notebook computers.

For the second quarter of 2008, large-size glass substrates accounted for 90% of . . .
