Arconic Inc. (NYSE: ARNC) today reported first quarter 2018 results, for
which the Company reported revenues of $3.4 billion, up 8% year over
year. Organic revenue¹ was up 4% year over year, driven
by higher volumes in the aerospace engines, automotive, commercial
transportation, building and construction, industrial and defense
markets, somewhat offset by declines in aerospace airframe production
mix and the industrial gas turbine market.

Net income in the first quarter was $143 million, or $0.29 per share.
These results include $26 million in special items, principally due to
costs associated with the early redemption of debt and
restructuring-related charges. First quarter 2017 net income was $322
million, or $0.65 per share. Net income excluding special items was $169
million, or $0.34 per share, versus $169 million, or $0.33 per share, in
the first quarter of 2017.

First quarter 2018 Operating income was $333 million, up 18% year over
year. Operating income excluding special items was $345 million, down
12% year over year, as the unfavorable impacts of higher aluminum
prices, performance shortfalls in our Rings, Disks and Global Rolled
Products operations, unfavorable aerospace wide-body production mix, and
the inventory impact of the new pension accounting standard more than
offset volume gains and net cost savings.

Arconic Chief Executive Officer Chip Blankenship said, “In the first
quarter, Arconic delivered solid organic revenue growth and free cash
flow in line with expectations. Operating income was negatively impacted
by higher aluminum prices and performance shortfalls in our Rings, Disks
and Global Rolled Products operations. During the quarter, I visited
several sites and was impressed by our dedicated talent and world-class
facilities. However, it is clear that we have areas in need of
operational improvement. To ensure all businesses execute consistently,
we are deploying targeted capital and expertise to close gaps. In
addition, we are updating our full year 2018 guidance due to rising
aluminum prices and my deeper understanding of our operations.”

Blankenship continued, “2018 is a transition year during which we are
making investments in our future to position the company for long-term
success and shareholder value creation.”

Arconic ended the first quarter 2018 with cash on hand of $1.2 billion.
Cash used for operations was $436 million, driven by the normal first
quarter build in working capital and semi-annual interest payments, as
well as higher pension contributions; cash used for financing activities
totaled $542 million, reflecting the payment of $517 million for the
early redemption of debt; and cash provided from investing activities
was $29 million. Free Cash Flow for the quarter was negative $417
million, which included $124 million of incremental pension
contributions compared to last year.

The Company reduced its pension liability by $315 million in the first
quarter 2018 driven by cash contributions and as a result of its
decision to freeze U.S. defined benefit pension plans for all U.S.-based
salaried and non-bargained hourly employees.

First Quarter 2018 Segment Performance

As of the first quarter of 2018, Arconic’s segment reporting measure has
changed from Adjusted EBITDA to Segment operating profit.

Engineered Products and Solutions (EP&S)

EP&S reported revenue of $1.5 billion, an increase of 4% year over year.
Organic revenue¹ was up 2% as volume growth in aerospace
engines, defense and industrial more than offset the continued downturn
in the industrial gas turbine market and headwinds in aerospace airframe
production mix, related to fastening systems. Segment operating profit
was $221 million, down $26 million year over year, as performance
shortfalls in Rings and Disks, unfavorable product mix, and higher input
costs more than offset the strength in aerospace engines. Segment
operating margin was 14.3%, down 230 basis points year over year.

Global Rolled Products (GRP)

GRP reported revenue of $1.4 billion, an increase of 9% year over year.
Organic revenue¹ was up 4%. Segment operating profit was $112
million, down $24 million year over year, driven by higher aluminum
prices and unfavorable aerospace wide-body production mix, partially
offset by higher automotive volume. Segment operating margin was 8.2%,
down 270 basis points year over year, including a 170 basis point
negative impact of higher aluminum prices.

Transportation and Construction Solutions (TCS)

TCS delivered revenue of $537 million, an increase of 18% year over
year. Organic revenue¹ was up 13%. Segment operating profit
was $67 million, down $1 million year over year, as higher volume in
commercial transportation and building and construction, favorable
foreign currency movements, and net cost savings were more than offset
by headwinds that included higher aluminum prices and unfavorable
product price and mix. Segment operating margin was 12.5%, down 240
basis points year over year, including a 350 basis point negative impact
of higher aluminum prices.

Early Debt Redemption

As disclosed on March 7, 2018, Arconic completed the previously
announced early redemption of all of its 5.72% Notes due in February
2019 in the aggregate principal amount of $500 million.

Strategy and Portfolio Review

In January 2018, Arconic initiated a review of its strategy and
portfolio. The Company is targeting to complete the work in the third
quarter 2018.

Updated Full Year 2018 Guidance*

Arconic is updating its full year 2018 guidance:

			4Q 2017			Updated 1Q 2018
Revenue			$13.4-$13.7 billion			$13.7-$14.0 billion
Earnings Per Share Excluding Special Items			$1.45-$1.55			$1.17-$1.27
Free Cash Flow			~$500 million			~$250 million

* Arconic has not provided a reconciliation of the forward-looking
financial measures of earnings per share excluding special items and
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.

Arconic will hold its quarterly conference call at 10:00 AM Eastern
Time on April 30, 2018 to present first quarter 2018 financial results.
The call will be webcast via

(1)		In the first quarter of 2018, Arconic adopted changes issued by the Financial Accounting Standards Board (FASB) to the presentation of net periodic pension cost and net periodic postretirement benefit cost. Based on the new guidance, Arconic has presented only the service cost component of net periodic benefit cost within Operating income (loss), while the non-service related components of net periodic benefit cost have been presented in the Other expense (income), net line item. Prior periods in 2017 have been recast to conform to this presentation. As a result, $38 of non-service related net periodic benefit cost was reclassified in each of the quarters ended December 31, 2017 and March 31, 2017 from various line items within Operating income (loss) to the Other expense (income), net line item. There was no impact to Net income (loss).
(2)		Interest expense for the quarter ended March 31, 2018 included $19 related to the early redemption of the Company’s outstanding 5.720% Senior Notes due 2019.
(3)		Other expense (income), net for the quarter ended December 31, 2017 included a favorable adjustment of $81 to the contingent earn-out liability related to the 2014 acquisition of Firth Rixson (Firth Rixson earn-out) and a favorable adjustment of $25 to a separation-related guarantee liability. Other expense (income), net for the quarter ended March 31, 2017 included a $351 gain on the sale of a portion of Arconic’s investment in Alcoa Corporation common stock.
(4)		In order to calculate both basic and diluted earnings (loss) per share, preferred stock dividends declared of $1 and $17 for the quarters ended March 31, 2018 and March 31, 2017, respectively, need to be subtracted from Net income (loss).
(5)		For the quarter ended March 31, 2018, the difference between the respective diluted average number of shares and the respective basic average number of shares relates to share equivalents (20 million) associated with employee stock options and awards and convertible debt (acquired through the acquisition of RTI International Metals, Inc (“RTI”)). For the quarter ended December 31, 2017, the diluted average number of shares does not include any share equivalents related to employee stock options and awards or convertible debt (acquired through the acquisition of RTI) as their effect was anti-dilutive due to the net loss for the quarter. For the quarter ended March 31, 2017, the difference between the respective diluted average number of shares and the respective basic average number of shares relates to share equivalents (60 million) associated with employee stock options and awards, convertible debt (acquired through the acquisition of RTI), and mandatory convertible preferred stock.

(1)		In the first quarter of 2018, Arconic adopted changes issued by the FASB to the classification of certain cash receipts and cash payments within the statement of cash flows. Based on the new guidance, Arconic classified cash received related to net sales of beneficial interest in previously transferred trade accounts receivables within investing activities. This new accounting standard does not reflect a change in our underlying business or activities. The prior period in 2017 has been recast to conform to this presentation, resulting in the reclassification of $95 from operating activities to investing activities for the three months ended March 31, 2017.
(2)		In the first quarter of 2017, Arconic sold 23,353,000 of its shares of Alcoa Corporation common stock at $38.03 per share which resulted in $888 in cash proceeds.
(3)		In the first quarter of 2017, Other investing activities included proceeds received from Alcoa Corporation’s sale of the Yadkin Hydroelectric Project.
(4)		In the first quarter of 2018, Arconic adopted changes issued by the FASB to the classification of cash and cash equivalents within the statement of cash flows. Based on the new guidance, Arconic classified restricted cash and the change in restricted cash within the cash and cash equivalents and net change in cash and cash equivalents line items. The prior period in 2017 has been recast to conform to this presentation, resulting in the reclassification of $14 from investing activities for the three months ended March 31, 2017.

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)		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.

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 (loss) 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 March 31, 2018, a charge for a number of small
  items ($2).
• for the quarter ended December 31, 2017, a charge resulting from the
  enactment of the U.S. Tax Cuts and Jobs Acts of 2017 that principally
  relates to the revaluation of U.S. deferred tax assets and liabilities
  from 35% to 21% ($272), a charge for a reserve against a foreign
  attribute resulting from the Company’s Delaware reincorporation ($23),
  partially offset by a benefit for the reversal of state valuation
  allowances ($69) and a benefit for a number of small items ($6);
• for the quarter ended March 31, 2017, a charge for a number of small
  items ($1).

⁽²⁾ Other special items included the following:

• 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 December 31, 2017, an impairment of goodwill
  related to the forgings and extrusions business ($719), a favorable
  adjustment to the Firth Rixson earn-out ($81), a favorable adjustment
  to a separation-related guarantee liability ($25), legal and other
  advisory costs related to Grenfell Tower ($7), costs associated with
  the Company’s Delaware reincorporation ($3), and a benefit for a
  number of small tax items ($11); and
• for the quarter ended March 31, 2017, a gain on the sale of a portion
  of Arconic’s investment in Alcoa Corporation common stock ($351),
  costs associated with the separation of Alcoa Inc. ($18), proxy,
  advisory and governance-related costs ($16), and a benefit for a
  number of small tax items ($8).

(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 the quarters ended March 31, 2018, and December 31, 2017, 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 ended March 31, 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, and the impact
of changes in aluminum prices and foreign currency fluctuations relative
to the prior year periods.

Cash receipts from sold receivables		136				287				95
Free cash flow		$	(417	)		$	376			$	(403	)

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
Free cash flow to include cash receipts from net sales of beneficial
interest in sold receivables. This change to our measure of 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 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		$	5,149			$	4,694			$	5,042			$	5,059			$	5,540

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.

RONA		8.6		%

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.
