Arconic Inc. (NYSE: ARNC) today reported second quarter 2018 results, for which the Company reported revenues of $3.6 billion, up 10% year over year. Organic revenue¹ was up 5% year over year, driven by higher volumes in the commercial transportation, automotive, aerospace engines, defense, and building and construction markets. This was partially offset by unfavorable aerospace wide-body production mix, and the negative impact of $38 million related to the settlements of certain customer claims.

Net income in the second quarter was $120 million, or $0.24 per share. These results include $65 million in special items, including the impact of $38 million related to the settlements of certain customer claims principally related to product introductions, discrete tax items associated with U.S. tax reform, and restructuring-related charges. Second quarter 2017 net income was $212 million, or $0.43 per share. Net income excluding special items was $185 million, or $0.37 per share, in the second quarter of 2018, versus $165 million, or $0.32 per share, in the second quarter of 2017.

Second quarter 2018 operating income was $324 million, up 1% year over year. Operating income excluding special items was $381 million, down 2% year over year, reflecting the impact of a $23 million charge related to a physical inventory adjustment in one facility, unfavorable aerospace wide-body production mix, and continued challenges in the Rings and Disks operations, mostly offset by higher volumes and net cost savings.

Arconic Chief Executive Officer Chip Blankenship said, “In the second quarter, Arconic delivered strong organic revenue growth and doubled adjusted free cash flow. We announced contract awards at the Farnborough International Airshow, providing groundwork for exciting growth with valued customers. We have initiated the sale process of our Building and Construction Systems business as the first outcome of our ongoing strategy review. Our team is delivering operational improvements where we need it the most. While there is plenty of work yet to be done, we are driving progress and generating positive momentum.”

Arconic ended the second quarter 2018 with cash on hand of $1.5 billion. Cash provided from operations was $176 million; cash used for financing activities totaled $35 million; and cash provided from investing activities was $117 million. Adjusted Free Cash Flow for the quarter was $289 million.

Second Quarter 2018 Segment Performance ²

Engineered Products and Solutions (EP&S)

EP&S reported revenue of $1.6 billion, an increase of 7% year over year. Organic revenue¹ was up 6% driven by volume growth in aerospace engines and defense. Segment operating profit was $212 million, down $38 million year over year, as a negative physical inventory adjustment of $23 million in one facility, unfavorable product mix, and continued challenges in Rings and Disks more than offset volume growth across all business units. Segment operating margin was 13.3%, down 350 basis points year over year.

Global Rolled Products (GRP)

GRP reported revenue of $1.5 billion, an increase of 14% year over year. Organic revenue¹ was up 5%. Segment operating profit was $123 million, down $10 million year over year, driven by unfavorable aerospace wide-body production mix and higher aluminum prices, partially offset by higher automotive and commercial transportation volume and net cost savings. Segment operating margin was 8.5%, down 200 basis points year over year, including a 120 basis point negative impact of higher aluminum prices.

Transportation and Construction Solutions (TCS)

TCS delivered revenue of $562 million, an increase of 12% year over year. Organic revenue¹ was up 11%. Segment operating profit was $97 million, up $26 million year over year, as higher volume in commercial transportation and building and construction, and net cost savings more than offset headwinds from higher aluminum prices. Segment operating margin was 17.3%, up 320 basis points year over year, including a 150 basis point negative impact of higher aluminum prices.

Full Year 2018 Guidance* Unchanged

Arconic’s full year 2018 guidance, which was previously announced on April 30, 2018, remains unchanged.

• Revenue of $13.7 billion to $14.0 billion
• Earnings Per Share Excluding Special Items of $1.17 to $1.27
• Adjusted Free Cash Flow of approximately $250 million

* Arconic has not provided a reconciliation of the forward-looking financial measures of earnings per share excluding special items and adjusted free cash flow to the most directly comparable financial measures prepared in accordance with accounting principles generally accepted in the United States of America (GAAP) because Arconic is unable to quantify certain amounts that would be required to be included in the GAAP measures without unreasonable efforts, and Arconic believes such reconciliations would imply a degree of precision that would be confusing or misleading to investors. In particular, reconciliations of the forward-looking non-GAAP financial measures to the most directly comparable GAAP measures are not available without unreasonable efforts due to the variability and complexity with respect to the charges and other components excluded from the non-GAAP measures, such as the effects of foreign currency movements, equity income, gains or losses on sales of assets, taxes and any future restructuring or impairment charges. These reconciling items are in addition to the inherent variability already included in the GAAP measures, which includes, but is not limited to, price/mix and volume.

Strategy and Portfolio Review

In January 2018, Arconic initiated a review of its strategy and portfolio. As part of that ongoing review, the Company has initiated the sale process of Arconic’s Building and Construction Systems (BCS) business.

The Company continues to target completion of the strategic review in the third quarter 2018. Arconic’s Investor Day, which will include the output of the strategic review and associated actions, is expected to be held in November 2018.

Expansion of Whitehall, MI and Morristown, TN Operations

Arconic is expanding its operations in Whitehall, Michigan, and Morristown, Tennessee, to provide additional capacity to meet growing demand from aerospace engine customers. The expansions total more than $100 million; about one-third of the total spend will happen in 2018 and is already included in the Company’s 2018 capital expenditures plan. The expansions are expected to be operational by the end of 2020.

Signed Largest Multiyear Supply Contract with Boeing

Arconic signed a new long-term contract with Boeing to supply aluminum sheet and plate for all models produced by Boeing Commercial Airplanes. The multiyear contract, which extends and adds to the 2014 contract between the companies, is the largest to date.

Renewal of Credit Facility

As previously reported, on June 29, 2018, Arconic entered into Amendment No. 2 to its Five-Year Revolving Credit Agreement, which, among other matters, provides that the Company’s $3 billion senior unsecured revolving credit facility will now mature on June 29, 2023, and includes certain improved terms.

Arconic will hold its quarterly conference call at 10:00 AM Eastern Time on July 31, 2018, to present second quarter 2018 financial results. The call will be webcast via www.arconic.com . Call information and related details are available at www.arconic.com under “Investors”; presentation materials will be available at approximately 8:00 AM Eastern Time on July 31.

In the first quarter of 2018, the Company changed its primary measure of segment performance from Adjusted EBITDA to Segment operating profit. Arconic’s definition of Segment operating profit is Operating income (loss) excluding Special items. Special items include Restructuring and other charges, and Impairment of goodwill. Segment operating profit may not be comparable to similarly titled measures of other companies. Prior period amounts have been recast to conform to current period presentation.

Segment operating profit also includes certain items which under the previous segment performance measure were recorded in Corporate, such as the impact of LIFO inventory accounting, metal price lag, intersegment profit eliminations, and derivative activities.

The difference between certain segment totals and consolidated amounts is Corporate.

(1)		Segment operating profit in the second quarter of 2018 included the impact of a $23 charge related to a physical inventory adjustment at one plant.
(2)		For the quarter ended March 31, 2017, Corporate expense included $18 of costs associated with the separation of Alcoa Inc. and $16 of proxy, advisory and governance-related costs. For the quarter ended June 30, 2017, Corporate expense included $42 of proxy, advisory and governance-related costs. For the quarter ended June 30, 2018, Corporate expense included $38 of costs related to settlements of certain customer claims primarily related to product introductions and $4 of legal and other advisory costs related to Grenfell Tower.
(3)		For the quarter ended June 30, 2017, Interest expense included $76 related to the early redemption of the Company’s outstanding 6.500% Senior Notes due 2018 and 6.750% Senior Notes due 2018 (collectively, the “2018 Senior Notes”) and a portion of the Company’s outstanding 5.720% Senior Notes due 2019. Interest expense for quarter ended March 31, 2018 included $19 related to the early redemption of the Company’s outstanding 5.720% Senior Notes due 2019.
(4)		For the quarter ended March 31, 2017, Other income (expense), net included a $351 gain on the sale of a portion of Arconic’s investment in Alcoa Corporation common stock. For the quarter ended June 30, 2017, Other income (expense), net included a $167 gain on the exchange of Arconic’s remaining investment in Alcoa Corporation common stock for a portion of the Company’s outstanding 2018 Senior Notes. For the quarter ended December 31, 2017, Other income (expense), net included favorable adjustments of $81 to the Firth Rixson earn-out and $25 to a separation-related guarantee liability.

Net income excluding Special items and Diluted EPS excluding Special items are non-GAAP financial measures. Management believes that these measures are meaningful to investors because management reviews the operating results of Arconic excluding the impacts of Restructuring and other charges, Discrete tax items, and Other special items (collectively, “Special items”). There can be no assurances that additional special items will not occur in future periods. To compensate for this limitation, management believes that it is appropriate to consider both Net income determined under GAAP as well as Net income excluding Special items.

(1)		Discrete tax items for each period included the following:
		•		for the quarter ended June 30, 2018, charges resulting from the Company’s ongoing analysis of the U.S. Tax Cuts and Jobs Acts of 2017 related to an increase in the provisional estimate of the one-time transition tax ($18) and Alternative Minimum Tax (AMT) credits expected to be refunded upon filing the 2018 tax return that will result in no benefit under government sequestration ($3);
		•		for the quarter ended March 31, 2018, a charge for a number of small items ($2);
		•		for the six months ended June 30, 2018, charges resulting from the Company’s ongoing analysis of the U.S. Tax Cuts and Jobs Acts of 2017 related an increase in the provisional estimate of the one-time transition tax ($18) and AMT credits expected to be refunded upon filing the 2018 tax return that will result in no benefit under government sequestration ($3), and a charge for a number of small items ($2); and
		•		for the six months ended June 30, 2017, a net charge for a number of small items ($1).
(2)		Other special items included the following:
		•		for the quarter ended June 30, 2018, costs related to settlements of certain customer claims primarily related to product introductions ($38) and legal and other advisory costs related to Grenfell Tower ($4);
		•		for the quarter ended March 31, 2018, costs related to the early redemption of the Company’s outstanding 5.720% Senior Notes due 2019 ($19), legal and other advisory costs related to Grenfell Tower ($5), and a charge for a number of small tax items ($1);
		•		for the quarter ended June 30, 2017, a gain on the exchange of the remaining portion of Arconic’s investment in Alcoa Corporation common stock ($167), costs associated with the Company’s early redemption of $1,250 of outstanding senior notes ($76), proxy, advisory and governance-related costs ($42), an unfavorable tax impact resulting from the difference between Arconic’s consolidated estimated annual effective tax rate and the statutory rate applicable to special items ($30), and a favorable tax impact related to the interim period treatment of operational losses in certain foreign jurisdictions for which no tax benefit was recognized ($4);
		•		for the six months ended June 30, 2018, costs related to settlements of certain customer claims primarily related to product introductions ($38), costs related to the early redemption of the Company’s outstanding 5.720% Senior Notes due 2019 ($19), legal and other advisory costs related to Grenfell Tower ($9), and a charge for a number of small tax items ($1); and
		•		for the six months ended June 30, 2017, a gain on the sale of a portion of Arconic’s investment in Alcoa Corporation common stock ($351), a gain on the exchange of the remaining portion of Arconic’s investment in Alcoa Corporation common stock ($167), costs associated with the Company’s early redemption of $1,250 of outstanding senior notes ($76), proxy, advisory, and governance-related costs ($58), costs associated with the separation of Alcoa Inc. ($18), an unfavorable tax impact resulting from the difference between Arconic’s consolidated estimated annual effective tax rate and the statutory rate applicable to special items ($13), and an unfavorable tax impact related to the interim period treatment of operational losses in certain foreign jurisdictions for which no tax benefit was recognized ($5).
(3)		The tax impact on special items is based on the applicable statutory rates whereby the difference between such rates and Arconic’s consolidated estimated annual effective tax rate is itself a Special item.
(4)		The average number of shares applicable to diluted EPS excluding Special items, includes certain share equivalents as their effect was dilutive. For all periods presented, share equivalents associated with outstanding employee stock options and awards and shares underlying outstanding convertible debt (acquired through the acquisition of RTI) were dilutive based on Net income excluding Special items.
		For the quarter and six months ended June 30, 2017, share equivalents associated with mandatory convertible preferred stock were anti-dilutive based on Net income excluding Special items.

Operational tax rate is a non-GAAP financial measure. Management believes that this measure is meaningful to investors because management reviews the operating results of Arconic excluding the impacts of Special items. There can be no assurances that additional Special items will not occur in future periods. To compensate for this limitation, management believes that it is appropriate to consider both the Effective tax rate determined under GAAP as well as the Operational tax rate.

Organic revenue is a non-GAAP financial measure. Management believes this measure is meaningful to investors as it presents revenue on a comparable basis for all periods presented due to the impact of the ramp-down and Toll Processing and Services Agreement with Alcoa Corporation at the North America packaging business at its Tennessee operations, the sale of the Fusina, Italy rolling mill, the sale of Latin America extrusions, and the impact of changes in aluminum prices and foreign currency fluctuations relative to the prior year periods.

Adjusted free cash flow		$	289			$	(417	)		$	143			$	(128	)		$	(260	)

There has been no change in the net cash funding in the sale of accounts receivable program in the second quarter of 2018. It remains at $350.

Adjusted free cash flow is a non-GAAP financial measure. Management believes that this measure is meaningful to investors because management reviews cash flows generated from operations after taking into consideration capital expenditures (due to the fact that these expenditures are considered necessary to maintain and expand Arconic’s asset base and are expected to generate future cash flows from operations), as well as cash receipts from net sales of beneficial interest in sold receivables. In conjunction with the implementation of the new accounting guidance on changes to the classification of certain cash receipts and cash payments within the statement of cash flows, specifically as it relates to the requirement to reclassify cash receipts from net sales of beneficial interest in sold receivables from operating activities to investing activities, the Company has changed the calculation of its measure of Adjusted free cash flow to include cash receipts from net sales of beneficial interest in sold receivables. This change to our measure of Adjusted free cash flow is being implemented to ensure consistent presentation of this measure across all historical periods. The adoption of this accounting guidance does not reflect a change in our underlying business or activities. It is important to note that Adjusted free cash flow does not represent the residual cash flow available for discretionary expenditures since other non-discretionary expenditures, such as mandatory debt service requirements, are not deducted from the measure.

Net debt is a non-GAAP financial measure. Management believes that this measure is meaningful to investors because management assesses Arconic’s leverage position after factoring in available cash that could be used to repay outstanding debt.

To compensate for this limitation, management believes that it is appropriate to consider both Operating income determined under GAAP as well as Operating income excluding Special items.

RONA is a non-GAAP financial measure. RONA is calculated as Net income excluding Special items divided by working capital and net PP&E. Management believes that this measure is meaningful to investors as RONA helps management and investors determine the percentage of net income the Company is generating from its assets. This ratio tells how effectively and efficiently the Company is using its assets to generate earnings.

			(1)		See Reconciliation of Net income excluding Special items for a description of Special items.
			(2)		The Deferred purchase program relates to an arrangement to sell certain customer receivables to several financial institutions on a recurring basis. Arconic is adding back the receivable for the purposes of the Working capital calculation.
