FRANKLIN, Tenn., April 24, 2024 (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, automotive extrusions, and other industrial applications, today announced first quarter 2024 results.

Management Commentary

“The year is off to a good start with our first quarter results surpassing our internal expectations on more normalized business conditions with improved operating efficiencies across all platforms,” said Keith A. Harvey, President and Chief Executive Officer. “Both the general engineering and automotive end markets are off to a faster start than expected at the beginning of the year while aerospace/high strength, which was strong year-over-year, was softer than our original expectations. As a result, we are maintaining our 2024 outlook. The investments we have made and are continuing to make in the business position Kaiser well to benefit from the next stage of our growth strategy in 2025. We remain committed to controlling costs, including the successful execution of our revised metal sourcing strategy, and improving overall operating efficiencies to drive profitable growth.”

First Quarter 2024 Financial Highlights

Net sales for the first quarter 2024 decreased modestly to $738 million compared to $808 million in the prior year period, reflecting a decrease in average selling price due to a 14% decrease in the hedged cost of alloyed metal, in addition to a 3% reduction in shipments, partially offset by a 2% increase in conversion revenue per pound.

Conversion revenue for the first quarter 2024 was $367 million, reflecting a 1% decrease compared to the prior year period.

• Net sales for the Company’s aerospace/high strength applications were $221 million, and conversion revenue was $137 million, reflecting a 12% increase primarily resulting from a 8% increase in shipments over the prior year quarter. The improvement reflects higher pricing, along with growth in shipments, driven by demand for our diversified applications.
• Net sales for packaging applications were $298 million, and conversion revenue was $118 million, reflecting an 11% decrease over the prior year quarter mainly due to a 7% reduction in shipments of primarily higher priced coated food products driven by anticipated destocking during the first quarter.
• Net sales for general engineering applications were $153 million, and conversion revenue was $80 million, reflecting a modest year-over-year increase on a 2% increase in shipments, which was partially offset by a lower value product mix.
• Net sales for automotive extrusions were $64 million, and conversion revenue was $31 million, relatively flat compared to the prior year period reflecting a 4% decrease in shipments, which was partly offset by improved pricing.

Reported net income for the first quarter 2024 was $25 million, or $1.51 income per diluted share, compared to net income and income per diluted share of $16 million and $0.99, respectively, in the prior year period. Excluding the impact of pre-tax, non-run-rate income of $10 million, adjusted net income was $17 million for the first quarter 2024, compared to adjusted net income of $7 million in the prior year period. Adjusted net income per diluted share was $1.02 for the first quarter 2024, compared to adjusted net income per diluted share of $0.42 for the first quarter 2023.

Adjusted EBITDA of $62 million in the first quarter 2024 increased $16 million compared to the prior year period and increased $11 million compared to the fourth quarter 2023. Adjusted EBITDA as a percentage of conversion revenue was 17.0% in the first quarter 2024 compared to 12.7% in the prior year period and 14.3% in the fourth quarter 2023.

Cash Flow and Liquidity

Adjusted EBITDA of $62 million reported in the first quarter 2024 and cash on hand funded $5 million of working capital, $30 million of capital investments, $10 million of interest payments and $13 million of cash returned to stockholders through quarterly dividends.

As of March 31, 2024, the Company had cash and cash equivalents of $102 million and borrowing availability under the Company’s revolving credit facility of $517 million, providing total liquidity of $619 million. There were no outstanding borrowings under the revolving credit facility as of March 31, 2024.

On April 15, 2024, the Company announced the declaration of a quarterly cash dividend of $0.77 per share which will be paid on May 15, 2024 to stockholders of record as of the close of business on April 25, 2024.

2024 Outlook

Kaiser remains well positioned in the current demand environment as a key supplier in diverse end markets with multi-year contracts with strategic partners. The Company expects demand will improve across the majority of its end markets throughout 2024. In aerospace/high strength applications, a more cautious outlook is warranted on expected build rates for domestic large commercial jet production in the near-term resulting in anticipated flat conversion revenue in 2024 following a strong 2023. The long-term demand outlook for these platforms remains unchanged. The Company believes demand for other aerospace/high strength applications remains strong. Now that destocking is complete, the Company expects the rest of its end markets to perform consistent with the prior outlook.

As a result, the Company continues to expect conversion revenue for the full year 2024 to improve 2% – 3% and adjusted EBITDA margins to improve 70 – 170 basis points over 2023 as it implements cost reduction measures in operations, increases manufacturing efficiencies and pursues its strategic growth initiatives.

Non-GAAP Financial Measures

This earnings release contains certain non-GAAP financial measures. A “non-GAAP financial measure” is defined as a numerical measure of a company’s financial performance that excludes or includes amounts so as to be different than the most directly comparable measure calculated and presented in accordance with GAAP in the statements of income, balance sheets, or statements of cash flow of the Company. Pursuant to the requirements of Regulation G, the Company has provided a reconciliation of non-GAAP financial measures to the most directly comparable financial measure in the accompanying tables.

The non-GAAP financial measures used within this earnings release are conversion revenue, adjusted operating income, adjusted EBITDA, adjusted net income, and adjusted earnings per diluted share which exclude non-run-rate items and ratios related thereto. As more fully described in these reports, “non-run-rate” items are items that, while they may occur from period to period, are particularly material to results, impact costs primarily as a result of external market factors and may not occur in future periods if the same level of underlying performance were to occur. These measures are presented because management uses this information to monitor and evaluate financial results and trends and believes this information to also be useful for investors. Reconciliations of certain forward looking non-GAAP financial measures to comparable GAAP measures are not provided because certain items required for such reconciliations are outside of the Company’s control and/or cannot be reasonably predicted or provided without unreasonable effort.
