Harvey, President and Chief Executive Officer. “For the full year 2020, value added revenue of $697 million declined approximately 19%, reflecting a strong first quarter, followed by significant COVID-19 related disruptions to our operations and end markets during the remainder of the year. Despite the decline in value added revenue, we reported a solid 22.1% adjusted EBITDA margin, reflecting our ability to quickly flex costs and operating levels in response to rapidly changing business conditions. These results were achieved with record safety performance for the entire year, a significant accomplishment and a testament to our people,” stated Mr. Harvey. “Our business model is to always be well-prepared for economic adversity, and the strength of our balance sheet and financial flexibility served us well, facilitating our ability to maintain our quarterly dividend and to opportunistically pursue further growth with our pending acquisition of Alcoa Warrick LLC, a leading producer of high margin beverage and food can stock for the North American packaging industry. With financial strength and continued confidence in the long-term outlook for our business, in early 2021 we increased our quarterly dividend by 7.5% to $0.72 per share, up from the 12% increase in early 2020, marking the tenth consecutive year we have increased the quarterly dividend,” stated Mr. Harvey. Full Year 2020 Management Summary For the full year 2020, Aero/HS demand declined sharply from the record 2019 levels reflecting the COVID-19 impact on commercial airline travel, delays in recertification of the Boeing 737 MAX and destocking within the supply chain. While commercial aerospace demand fell sharply in the second half, the Company experienced strong demand throughout the year for its defense related applications, specifically from the F-35 Joint Strike Fighter program and other legacy military aircraft programs. Automotive extrusion demand regained strength following significant but temporary COVID-19 related supply chain shutdowns in the second quarter. Planned program launches for multiple new platforms ramped up during the second half, and new programs were awarded during the year reflecting the continued trend for aluminum content growth. Demand for the Company’s general engineering products reflected steady underlying demand driven in part by strength in semi-conductor and automotive applications, restocking in the supply chain and strong customer preference for KaiserSelect® plate. 2021 Outlook “For the full year 2021, we anticipate total value added revenue up 5% to 10% year-over-year and an adjusted EBITDA margin comparable to 2020 driven by strong growth in automotive, defense and general engineering applications,” stated Mr. Harvey. The Company anticipates value added revenue for the Company’s aerospace/high strength applications to be down 5% to 8% year-over-year on slightly lower shipments compared to 2020, which reflected strong demand for our commercial aerospace applications during the first half of 2020. Commercial aerospace demand continues to reflect weak airline travel impacted by the pandemic and destocking in the supply chain. The Company continues to anticipate full recovery of commercial aerospace in 2023-2024. Lower commercial aerospace demand in 2021 is expected to be mitigated in part by continued strength in demand for defense applications as build rates for the F-35 Joint Strike Fighter are expected to increase 20% to 30% compared to the prior year while business and regional jet demand continues to improve. Value added revenue and shipments for the Company’s automotive extrusion applications are anticipated to increase 35% to 45% year-over-year as North American build rates are expected to increase more than 25% to approximately 16 million units in 2021 from 13 million units in 2020, and numerous new product launches in 2020 and 2021 increase the Company’s aluminum content on vehicles. General engineering value added revenue and shipments are anticipated to increase 10% to 15% year-over-year reflecting solid service center and end market demand driven by continued growth in semi-conductor and automotive demand. In addition, reshoring continues as many North American OEM’s secure domestic supply for their raw material needs to minimize risk of supply chain disruption. “Our planned acquisition of Alcoa Warrick LLC provides an opportunity for further value creation with strong secular growth in the non-cyclic packaging business,” stated Mr. Harvey. “The transaction is anticipated to close on March 31, 2021 and is expected to be immediately accretive to earnings and cash flow. The outlook for the beverage and food packaging markets is strong with favorable demand and industry dynamics driving growth. North American can demand was up 5% year-over-year in 2020 and is projected to increase an additional 3% to 5% in 2021. The Warrick rolling mill is one of only four dedicated can sheet mills in North America and we expect to become a significant participant in the supply chain solution in meeting the growing North American demand. We will provide a further update on our consolidated full year outlook for 2021 during our first quarter earnings call in April 2021,” concluded Mr. Harvey.

Totals may not sum due to rounding. Fourth Quarter 2020 Net sales for the fourth quarter 2020 were $272 million compared to $369 million in the prior year period, reflecting a 22% decrease in shipments and a 6% decrease in average selling price. The decrease in average selling price reflected an approximately 9% decrease in value added revenue per pound and a 1% decrease in underlying contained metal costs. Value added revenue for the fourth quarter 2020 decreased to $152 million from $213 million in the prior year period, primarily driven by the decline in commercial aerospace demand. Value added revenue for the Company’s aerospace/high strength applications decreased 54% to $64 million and shipments decreased 58% reflecting the impact of the COVID-19 pandemic on commercial aerospace demand, while demand for defense applications remained strong. Value added revenue for automotive extrusions increased 16% to $26 million, on a 14% increase in shipments, reflecting continued strength in demand. Value added revenue for general engineering applications increased approximately 18% to $61 million on a 14% increase in shipments reflecting solid underlying demand and stable pricing. Adjusted EBITDA of $29 million in the fourth quarter 2020 decreased $24 million compared to the prior year period reflecting the total sales impact of approximately $30 million, offset by lower costs flexed with the reduction in volume. Adjusted EBITDA as a percentage of value added revenue was 18.8% in the fourth quarter 2020 as compared to 24.5% in the prior year period. Reported operating income for the fourth quarter 2020 was approximately $19 million. Adjusting for approximately $3 million of non-run-rate benefits, operating income for the fourth quarter 2020 was approximately $15 million, compared to $40 million in the prior year quarter. Reported net income for the fourth quarter 2020 was $6 million, or $0.37 per diluted share, compared to net loss and diluted loss per share of $11 million and $0.66, respectively, for the prior year period. Excluding the impact of non-run-rate items, adjusted net income was $6 million or $0.35 per diluted share for the fourth quarter 2020, compared to adjusted net income of $29 million or $1.79 per diluted share for the fourth quarter 2019, reflecting the impact of the lower operating income as discussed above and approximately $5 million of additional pre-tax interest expense related to senior notes issued earlier in the year. Full Year 2020 Net sales for the full year 2020 were $1,173 million compared to $1,514 million in the prior year period, reflecting a 20% decrease in shipments and a 4% decrease in average selling price. The decrease in average selling price reflected an approximately 1% increase in value added revenue per pound and a 10% decrease in underlying contained metal costs. Value added revenue for the full year 2020 decreased to $697 million from $856 million in the prior year period, reflecting a 20% decrease in shipments primarily reflecting the COVID-19 impact on demand for the Company’s aerospace/high strength applications in the second half 2020 due to a significant decline in commercial airline travel, delays in recertification of the Boeing 737 MAX and destocking within the supply chain. Value added revenue for the Company’s aerospace/high strength applications decreased 28% to $369 million on a 37% decrease in shipments reflecting the significant decline in commercial aerospace compared to the strong demand levels in the prior year, mitigated in part by strong demand for the Company’s defense applications as previously mentioned and $15 million related to modifications to 2020 customer declarations under multi-year contracts. Value added revenue for automotive extrusions decreased 11% to $83 million, on an 11% decrease in shipments, reflecting strong first quarter shipments and a sharp recovery following the temporary shutdown of the North American supply chain during the second quarter, and higher industry build rates than initially forecast. Value added revenue for general engineering applications increased approximately 3% to $239 million on relatively flat shipments compared to the prior year period reflecting solid underlying demand and stable pricing throughout the year. Adjusted EBITDA of $154 million in the full year 2020 decreased $59 million compared to the prior year period reflecting the negative sales impact of $74 million and $14 million of manufacturing cost inefficiencies, partially offset by a $17 million reduction in plant and corporate overhead costs, and approximately $12 million of lower planned major maintenance and incentive costs. Adjusted EBITDA as a percentage of value added revenue was 22.1% in the full year 2020, compared to 24.9% in the prior year period reflecting strong execution in flexing costs and operations with changes in market dynamics. Reported operating income for the full year 2020 was $81 million. Adjusting for approximately $21 million of non-run-rate charges, operating income for the full year 2020 was $102 million, compared to $164 million in the prior year period due to the items previously mentioned and approximately $3 million of higher depreciation expense. The $21 million of non-run-rate charges primarily reflected an $8 million restructuring charge for severance and benefit costs, a $5 million reserve increase for on-going legacy environmental clean-up projects and $6 million related to diligence and legal fees associated with the pending acquisition of Alcoa Warrick LLC. Reported net income for the full year 2020 was $29 million, or $1.81 per diluted share, compared to net income and diluted earnings per share of $62 million and $3.83, respectively, for the prior year period. Excluding the impact of non-run-rate items, adjusted net income was $48 million or $3.01 per diluted share for the full year 2020, compared to adjusted net income of $111 million or $6.85 per diluted share for the full year 2020, reflecting the impact of lower operating income and $16 million of additional pre-tax interest expense. Cash Flow and Balance Sheet In the full year 2020, adjusted EBITDA of $154 million funded approximately $52 million of capital investments, $29 million of interest payments and $56 million of cash returned to shareholders through dividends and share repurchases. As of December 31, 2020, the Company had cash and cash equivalents of approximately $780 million, and borrowing availability under the Company's revolving credit facility of approximately $252 million providing total liquidity of $1 billion. There were no borrowings under the revolving credit facility during the year and the facility remains undrawn. The Company anticipates capital spending for the full year 2021 of $50 million to $60 million, primarily focused on sustaining capital investment. The Company will provide further updates regarding capital spending for 2021 following completion of the pending acquisition of Alcoa Warrick LLC. The acquisition of Alcoa Warrick LLC is expected to close on March 31, 2021. The Company intends to fund the purchase price with $587 million of existing cash on hand, and the assumption of $83 million of other post-employment benefits (“OPEB”) liabilities, and other customary post-closing adjustments.
