Corning Reports Fourth-Quarter and Full-Year 2017 Financial Results and Continued Progress on Strategy and Capital Allocation Framework

CORNING, N.Y. — Corning Incorporated (NYSE: GLW) today announced results for fourth-quarter and full-year 2017.

News Summary:

Strong fourth-quarter finishes an excellent 2017

Full-year GAAP sales of $10.1 billion, up 8%, and full-year GAAP EPS of $(0.66), compared to $3.23 in 2016; Q4 GAAP sales of $2.6 billion, up 7% year over year, and Q4 GAAP EPS of $(1.66)

2017 core sales of $10.5 billion, up 8%; core EPS of $1.72, up 11%

Fourth-quarter core sales of $2.7 billion, up 7% year over year, and core EPS of $0.49

Full-year and fourth-quarter 2017 core results have been adjusted to exclude $1.8 billion in non-cash items related to tax reform

Significant progress on Strategy and Capital Allocation Framework halfway through four-year plan

Returned $9 billion to shareholders and on a path to return more than $12.5 billion

All five market-access platforms delivered key milestones, including: major customer agreements and product wins; strategic acquisitions; and sales of new products in existing and emerging businesses

2017 results demonstrated benefits of growth investments:

Optical Communications’ full-year sales increase of 18%, and significant progress toward 2020 goal of $5 billion in sales

Specialty Materials’ full-year sales growth of 25%, driven by strong adoption of Corning® Gorilla® Glass technologies

Environmental Technologies’ full-year sales growth of 7%, with first sales of gas particulate filters initiating progress toward building a new $500 million business

2018 highlights expected to include sales of approximately $11 billion, continued innovation and growth investments, and further improvement in LCD pricing to mid-single digit percentage declines

“Strong growth and strong investment made 2017 an outstanding year. We exited the year running at full capacity in several of our businesses and with committed customer demand that supports our current capacity-expansion initiatives. We expect to see the benefits of these initiatives in the second half of 2018 and beyond as production ramps,” said Wendell P. Weeks, chairman, chief executive officer, and president. “2018 will be another year of strong growth and investment, consistent with our Strategy & Capital Allocation Framework. We feel great about our progress and prospects.”

Strategy and Capital Allocation Framework Progress

“We’re proud of our 2017 performance,” Weeks continued. “But it’s important to recognize that our achievements are not just the result of strong execution this year. Our success stems from the Strategy and Capital Allocation Framework that we introduced more than two years ago, and its focus on what’s best for Corning and its stakeholders.”

The Framework outlines the company’s 2016-2019 leadership priorities. Under the Framework, Corning plans to deliver more than $12.5 billion to shareholders while investing $10 billion in growth opportunities. Since it was announced in October 2015, the company has achieved key milestones including the return of $9 billion to shareholders through dividends, which have increased 29%, and share repurchases, which have reduced outstanding shares by 30%.

“The strategic and financial benefits of Corning’s focused portfolio are increasingly evident as we enter the third year under our Framework,” Weeks said. “We’re particularly pleased with significant achievements across our market-access platforms.”

Highlights of progress in Corning’s market-access platforms include: a major contract with Verizon for next generation networks, and two significant acquisitions in Optical Communications; initiating shipment of the world’s first Gen 10.5 glass and capturing opportunities for Corning® Iris™ Glass in Display; celebrating the 10th anniversary of Corning® Gorilla® Glass with new applications and more glass on devices in Mobile Consumer Electronics; winning the majority of awarded platforms for gas particulate filters and advancing Gorilla Glass for Automotive to 35 platform wins; and introducing Valor™ Glass, a revolutionary new pharmaceutical packaging solution, and related manufacturing capacity plans in Life Sciences Vessels.

“In 2018, we will continue to advance the objectives of our Strategy and Capital Allocation Framework,” Weeks added. “Our results and outlook confirm that we have the right strategy in place to achieve the goals of our Framework and drive consistent growth.”

Full-year core sales in Display Technologies were $3.4 billion, and core earnings were $944 million. For the full-year, volume was up mid-single digit percentages, in line with our expectations. Pricing improved as anticipated, and reached single-digit percentage declines year over year in both the third and fourth quarters of 2017.

Fourth-quarter core sales were $847 million, and core earnings were $221 million. In the fourth quarter, volume was up slightly sequentially, in line with the market.

For full-year 2018, Corning expects LCD glass market growth to be in the mid-single digit percentages, similar to 2017, as screen size growth continues. The company expects Corning’s volume to grow faster than the market as Corning supports the ramp-up of the world’s first Gen 10.5 fab. The improvements in LCD glass pricing are expected to continue in 2018, with full-year price declines expected to reach the mid-single digit percentages.

Optical Communications:



	Q4 2017		Q3 2017		% change	Q4 2016		% change		Full-year 2017		Full-year 2016	% change

Optical Communications had a very strong year, with full-year 2017 sales of $3.5 billion, up 18%, and core earnings up 33%. Sales growth in both enterprise and carrier businesses, as well as contributions from acquisitions, drove the outstanding results. Fourth-quarter sales increased 13% year over year.

2018 full-year Optical Communications sales are expected to increase by about 10%, excluding any contribution from the pending acquisition of 3M’s Communications Markets Division.

Environmental Technologies:



	Q4 2017		Q3 2017		% change	Q4 2016		% change		Full-year 2017		Full-year 2016	% change
GAAP Net Sales	$	291	$	277	5%	$	245	19%	$	1,106	$	1,032	7%

In Environmental Technologies, 2017 sales, including the first sales of gas particulate filters, were $1.1 billion, up 7%, driven by worldwide auto market growth and new business wins. Core earnings were $139 million, as capacity and engineering investments partially offset the benefits of sales growth. Fourth-quarter sales grew 19% year over year, with core earnings up 33%.

For 2018, Environmental Technologies sales are expected to increase by a high-single digit percentage.

Use of Non-GAAP Financial Measures

CORE PERFORMANCE MEASURES

In managing the Company and assessing our financial performance, we supplement certain measures provided by our consolidated financial statements with measures adjusted to exclude certain items, to arrive at core performance measures. We believe that reporting core performance measures provides investors greater transparency to the information used by our management team to make financial and operational decisions. Corning has adopted the use of constant currency reporting for the Japanese yen and South Korean won, and uses an internally derived yen-to-dollar management rate of ¥99 and won-to-dollar management rate of ₩1,100. The Company believes that the use of constant currency reporting allows investors to understand our results without the volatility of currency fluctuations, and reflects the underlying economics of the translated earnings contract used to mitigate the impact of changes in currency exchange rates on our net sales and net income.

Net sales, equity in earnings of affiliated companies and net income are adjusted to exclude the impacts of changes in the Japanese yen and the South Korean won, gains and losses on our translated earnings contracts, acquisition-related costs, certain discrete tax items, restructuring and restructuring-related charges, certain litigation-related expenses, pension mark-to-market adjustments and other items which do not reflect on-going operating results of the Company or our equity affiliates. Management’s discussion and analysis on our reportable segments has also been adjusted for these items, as appropriate. These measures are not prepared in accordance with Generally Accepted Accounting Principles in the United States (“GAAP”). We believe investors should consider these non-GAAP measures in evaluating our results as they are more indicative of our core operating performance and how management evaluates our operational results and trends. These measures are not, and should not be viewed as a substitute for GAAP reporting measures. With respect to the Company’s outlooks for future periods, it is not able to provide reconciliations for these non-GAAP measures because the Company does not forecast the movement of the Japanese yen and South Korean won against the U.S. dollar, or other items that do not reflect ongoing operations, nor does it forecast items that have not yet occurred or are out of the Company’s control. As a result, the Company is unable to provide outlook information on a GAAP basis.

See “Use of Non-GAAP Financial Measures” for details on core performance measures. For a reconciliation of non-GAAP performance measures to their most directly comparable GAAP financial measure, please see “Reconciliation of Non-GAAP Measures” below.

Items which we exclude from GAAP measures to arrive at Core performance measures are as follows:



(1)	Constant-currency adjustments:
	Constant-yen: Because a significant portion of Display Technologies segment revenues and manufacturing costs are denominated in Japanese yen, management believes it is important to understand the impact on core earnings of translating yen into dollars. Presenting results on a constant-yen basis mitigates the translation impact of the Japanese yen, and allows management to evaluate performance period over period, analyze underlying trends in our businesses, and establish operational goals and forecasts. As of January 1, 2015, we use an internally derived management rate of ¥99, which is closely aligned to our current yen portfolio of foreign currency hedges, and have recast all periods presented based on this rate in order to effectively remove the impact of changes in the Japanese yen.
	Constant-won: Because a significant portion of Corning Precision Materials’ costs are denominated in Korean won, management believes it is important to understand the impact on core earnings from translating won into dollars. Presenting results on a constant-won basis mitigates the translation impact of the Korean won, and allows management to evaluate performance period over period, analyze underlying trends in our businesses, and establish operational goals and forecasts without the variability caused by the fluctuations caused by changes in the rate of this currency. We use an internally derived management rate of ₩1,100, which is consistent with historical prior period averages of the won.
(2)	Translation gain on Japanese yen-denominated debt: The gain on the translation of our Yen-denominated debt to U.S. dollars.
(3)	Translated earnings contract gain (loss): We have excluded the impact of the realized and unrealized gains and losses of our Japanese yen and South Korean won-denominated foreign currency hedges related to translated earnings, as well as the unrealized gains and losses of our euro, New Taiwan dollar and Chinese yuan-denominated foreign currency hedges related to translated earnings.
(4)	Acquisition-related costs: These expenses include intangible amortization, inventory valuation adjustments and external acquisition-related deal costs.
(5)	Discrete tax items and other tax-related adjustments: This represents the removal of discrete adjustments (e.g. changes in tax law and changes in judgment about the realizability of certain deferred tax assets) as well as other non-operational tax-related adjustments.
(6)	Litigation, regulatory and other legal matters: Includes amounts related to legal matters.
(7)	Restructuring, impairment and other charges: This amount includes restructuring, impairment and other charges, including goodwill impairment charges and other expenses and disposal costs not classified as restructuring expense.
(8)	Equity in earnings of affiliated companies: These adjustments relate to items which do not reflect expected on-going operating results of our affiliated companies, such as restructuring, impairment and other charges and settlements under “take-or-pay” contracts.
(9)	Adjustments related to acquisitions: Includes fair value adjustments to the Corning Precision Materials indemnity asset related to contingent consideration, post-combination expenses and other acquisition and disposal adjustments.
(10)	Pension mark-to-market adjustment: Defined benefit pension mark-to-market gains and losses, which arise from changes in actuarial assumptions and the difference between actual and expected returns on plan assets and discount rates.
(11)	Gain on realignment of equity investment: Gain recorded upon the completion of the strategic realignment of our ownership interest in Dow Corning.
(12)	Taiwan power outage: Impact of the power outage that temporarily halted production at our Tainan, Taiwan manufacturing location in the second quarter of 2016. The impact includes asset write-offs and charges for facility repairs, offset somewhat by partial reimbursement through our insurance program.
(13)	Adjustments to remove the impact of the Tax Cuts and Job Act: Includes a provisional amount related to the one-time mandatory tax on unrepatriated foreign earnings, a provisional amount related to the remeasurement of U.S. deferred tax assets and liabilities, changes in valuation allowances as a result of the 2017 Tax Act, and adjustments for the elimination of foreign tax credits.
