FOOTHILL RANCH, Calif., July 21, 2021 (GLOBE NEWSWIRE) -- Kaiser Aluminum Corporation (NASDAQ:KALU), a leading producer of semi-fabricated specialty aluminum products, serving customers worldwide with highly-engineered solutions for aerospace and high-strength, packaging, general engineering, custom automotive and other industrial applications, today announced second quarter and first half 2021 results.
Second Quarter 2021 Management Summary
“Solid second quarter value added revenue of $318 million and adjusted EBITDA of $59 million reflect the first full quarter results of our recently acquired Warrick Rolling Mill along with continued improvement in our end markets,” said Keith A. Harvey, President and Chief Executive Officer. “Our commercial aerospace end market is beginning to demonstrate positive momentum as air travel continues to recover and demand for our defense related applications remains strong. Demand for our packaging and general engineering applications is robust, and although our automotive business is temporarily dampened as ongoing shortages of semiconductor chips affects North American light vehicle production, we anticipate this issue will abate and volume will recover in the second half of 2021.
“Our integration of the Warrick Rolling Mill continues to proceed on track and our teams are working diligently to exit transition service agreements by the end of the year. Until that time, we will continue to incur transition costs and overhead redundancies. In addition, with increasing end market demand and a solid economy, we are experiencing inflationary cost pressures from rising freight, labor and materials costs and the challenge to efficiently meet demand. Our operations and commercial teams are working to mitigate the impact of these issues on our results,” stated Mr. Harvey.
Outlook
The Company anticipates improving trends across its end markets with strong secular demand growth for aerospace, packaging, and automotive along with solid market dynamics continuing to support growth in its general engineering applications.
Aerospace is beginning to build positive momentum as commercial air travel recovers and aerospace/high strength demand is expected to continue improving through the balance of 2021 driven by growth in defense related programs and business jet production. The Company continues to expect the aerospace market to recover to record 2019 levels by 2023/2024 timeframe and then resume its pre-pandemic 3% to 4% CAGR.
Demand for the Company’s automotive applications remains robust with multiple new programs successfully launched and underway. Over the longer term, the Company anticipates a greater than 5% CAGR for automotive demand growth driven by light weighting and fuel efficiency with further opportunities as the shift to electric vehicles continues.
Demand for the Company’s general engineering applications remains strong, led by service center restocking and stronger demand as the markets recover from the pandemic. In addition, as the Company has previously noted, reshoring of supply lines in North America as OEM’s shift supply strategies to have a larger portion of their material needs sourced domestically provides significant upside for further growth opportunities.
In addition to diversifying the business, the Company’s re-entry into packaging through the Warrick Rolling Mill provides a significant opportunity for further long-term growth as food and beverage packaging continues to shift to aluminum in response to growing consumer demand. North American aluminum packaging markets are expected to remain in deficit for the foreseeable future as the strongly preferred, North American supply struggles to keep pace with North American demand. The Company anticipates a 3% to 5% CAGR over the next several years.
“With a diversified portfolio and strong secular growth trends in each of our end markets, we plan to invest in several strategic growth initiatives,” said Mr. Harvey. “In packaging, we plan to meet the rapidly increasing needs of our customers with a series of strategic investments backed by strong, long-term contracts reflecting significant margin improvement facilitated by the current market environment, improved efficiencies and expected synergies. The initial investment of $150 million at our Warrick facility will be for an additional roll coat line that is expected to be qualified and operational by early 2024, with other investments to follow as we continue to evaluate customer demand requirements.
“In addition, as end market demand further improves we expect to proceed with the previously discussed $225 million, Phase VII expansion project at our Trentwood facility, which will increase capacity approximately 25% to meet the needs of our flat-rolled aerospace and general engineering customers well into the remainder of this decade, while further enhancing product quality and improving efficiencies. Finally, smaller capital investments of approximately $25 million will further enhance our ability to support growth in automotive and general engineering long products. We anticipate the total $400 million of growth focused capital spending will occur over the next several years, funded by a combination of our operations and strong balance sheet.
“As we look forward, with the expected recovery rates of our end markets and the planned strategic investments, we will be well-positioned over the longer-term to deliver value added revenue approaching $2.0 billion with a mid to high 20% adjusted EBITDA margin,” concluded Mr. Harvey.

First Half 2021 Compared to Second Half 2020
Net sales for the first half 2021 were $1,065 million compared to $528 million in the second half 2020, reflecting a 107% increase in shipments and a 3% decrease in average selling price per pound. The decrease in average selling price reflected an approximately 23% decrease in value added revenue per pound and a 26% increase in underlying contained metal costs.
Value added revenue for the first half 2021 increased 60% to $490 million from $306 million in the second half 2020, reflecting $132 million of value added revenue from the Company’s recently acquired packaging business and continued improvement in each of its other end markets. Value added revenue for the Company’s aerospace/high strength applications increased 10% to $151 million on a 31% increase in shipments compared to the second half 2020, which included approximately $15 million of additional revenue recognized in the third quarter related to modifications to the 2020 customer declarations under multi-year contracts. The increase in value added revenue and shipments reflects continued strength in demand for defense related applications and improving demand for commercial aerospace as air travel continues to recover. Value added revenue for automotive extrusions increased 5% to $53 million, on a slight increase in shipments reflecting the temporary impact on North American production due to the shortage of semiconductor chips. Value added revenue for general engineering applications increased approximately 28% to $149 million on a 31% increase in shipments reflecting strong underlying semiconductor, industrial and machine tool demand and restocking in the service center supply chain.
Adjusted EBITDA of $96 million in the first half 2021 increased $36 million compared to the second half 2020 reflecting the increase in value added revenue partially offset by higher freight, benefit and incentive costs in addition to higher overhead costs related to integration of the Company’s recent acquisition of the Warrick Rolling Mill. Adjusted EBITDA as a percentage of value added revenue was 19.6% in the first half 2021, comparable to the second half 2020. Adjusted EBITDA margin in the first half 2021 reflected the items noted in addition to portfolio product mix.
Second Quarter 2021
Net sales for the second quarter 2021 increased to $741 million compared to $276 million in the prior year period, reflecting a 184% increase in shipments and a 5% decrease in average selling price per pound. The decrease in average selling price reflected an approximately 36% decrease in value added revenue per pound and a 48% increase in underlying contained metal costs.
Value added revenue for the second quarter 2021 increased 82% to $318 million from $175 million in the prior year period driven primarily by the addition of the acquired packaging business and continued improvement in the Company’s general engineering and automotive applications. Value added revenue for the Company’s aerospace/high strength applications decreased 22% to $80 million on a 15% decrease in shipments 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 176% to $25 million, reflecting a 148% increase in shipments primarily reflecting recovery from the COVID -19 related automotive supply chain shut downs during the prior year period. Value added revenue for general engineering applications increased approximately 25% to $77 million on a 37% increase in shipments reflecting solid underlying demand.
Adjusted EBITDA of $59 million in the second quarter 2021 increased $24 million compared to the prior year period reflecting the higher value added revenue offset by higher manufacturing and overhead costs. Adjusted EBITDA as a percentage of value added revenue was 18.5% in the second quarter 2021 as compared to 19.7% in the prior year period.
Reported operating income for the second quarter 2021 was approximately $11 million. Adjusting for approximately $22 million of non-run-rate charges, including $3 million of Warrick related integration costs and $19 million of non-cash charges predominately associated with one-time purchase accounting adjustments related to hedging and LIFO inventory, operating income for the second quarter 2021 was approximately $33 million, compared to $21 million in the prior year quarter. In addition, adjusted operating income in the second quarter 2021 reflected approximately $13 million of higher depreciation and amortization expense.
Reported net loss for the second quarter 2021 was $22 million, or $1.42 loss per diluted share, compared to a net loss and loss per diluted share of $7 million and $0.41, respectively, for the prior year period. Excluding the impact of non-run-rate items, and the after-tax impact of $36 million associated with the Company’s senior note refinancing, adjusted net income was $16 million or $1.00 per diluted share for the second quarter 2021, compared to adjusted net income of $6 million or $0.36 per diluted share for the second quarter 2020. Adjusted net income in the second quarter 2021 also reflected the impact of the higher operating income as discussed above and approximately $2 million of additional pre-tax interest expense related to the Company’s new senior notes.
Cash Flow and Liquidity
Adjusted EBITDA of $96 million reported in the first half of 2021 funded approximately $18 million of capital investments, $24 million of interest payments and $23 million of cash returned to shareholders through quarterly dividends.
During the second quarter 2021, the Company issued $550 million of new 4.50% senior notes that mature in 2031 resulting in proceeds of $541 million, net of $9 million of transaction fees, and redeemed $350 million of 6.50% senior notes with a maturity of 2025 resulting in net proceeds of approximately $160 million.
As of June 30, 2021, the Company had cash and cash equivalents of approximately $283 million, and borrowing availability under the Company's revolving credit facility of approximately $367 million providing total liquidity of $650 million. There were no borrowings under the revolving credit facility during the quarter and the facility remains undrawn.
The Company anticipates total capital spending of $80 million to $90 million for the full year 2021, slightly higher than its previous outlook to reflect pre-spending associated with the growth capital investments as noted.
