o**Liquidity remained strong at $615 Million as of December 31, 2022**

**FRANKLIN, Tenn., February 22, 2023** - 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 fourth quarter and full year 2022 results.

As announced on January 26, 2023, the Company renamed its previously used non-GAAP financial measure "value added revenue", or "VAR", to "Conversion Revenue." In addition, effective January 1, 2022, the Company prospectively changed its approach from including a portion of alloyed metal cost within Hedged Cost of Alloyed Metal to include all alloyed metal cost. This approach is in further alignment with the Company's change in pricing and certain customer-renegotiated contracts to more fully pass through alloy cost due to the high inflationary and historically unprecedented volatility of these costs starting in early 2022. The Company further announced on January 26, 2023, the revision of its presentation of Adjusted EBITDA to no longer adjust the Company's operating results for the impact of the last-in, first out inventory valuation ("LIFO") calculated on an annual basis to LIFO calculated on a monthly basis done at a plant level, previously identified as "Adjustments to plant-level LIFO". This change had a consequential impact on certain other non-GAAP measures including: Operating income, excluding operating non-run-rate ("NRR") items, Adjusted net income (loss) and Adjusted earnings (loss) per diluted share.

**2022 Management Commentary**

"The full year 2022 was pivotal in Kaiser's evolution as we laid the necessary groundwork to position the Company for long-term, sustainable growth despite the numerous challenges we encountered, including unprecedented supply chain disruptions, inflationary cost pressures and labor turnover, which negatively impacted our financial performance," said Keith A. Harvey, President and Chief Executive Officer. "We continue to work with our customers to negotiate improvements to commodity price adjustments to mitigate the impact of inflationary and volatile commodity costs on our business and improve our margin profile. We are prioritizing investments in our growth through our roll coat capacity expansion project at Warrick, which we expect will become operational by mid-to-late 2024. In addition, we remain well positioned to service the recovery we have been experiencing in aerospace and continued demand for general engineering (plate) following the completion of a long planned, major outage at our Trentwood facility in the third quarter of 2022."

Mr. Harvey continued, "Looking ahead, we remain intently focused on continuing to pursue cost reductions in our operations, as well as improving efficiencies and implementing commercial actions to increase our margins. We believe the strategy we have in place should lead to improved performance in the year ahead with our full year 2022 Adjusted EBITDA representing the trough. While our efforts will take time to manifest, we are confident in our ability to execute given our solid market position as a key supplier, focus on diverse end markets with strong secular growth characteristics, deep customer relationships and multi-year contracts with strategic partners."

**Fourth Quarter 2022 Financial Highlights**

Net sales for the fourth quarter 2022 decreased to $776 million compared to $806 million in the prior year period, reflecting a 9% decrease in shipments and a 6% increase in average selling price per pound. The increase in average selling price reflected a 24% increase in conversion revenue per pound and a 5% decrease in underlying contained metal costs.

Conversion revenue for the fourth quarter 2022 was $356 million. The impact of the aforementioned change to include all alloyed metal cost within Hedged Cost of Alloyed Metal in comparison to the Company's historical presentation resulted in a reduction of approximately $37 million in conversion revenue for the fourth quarter of 2022.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Conversion revenue for the Company's aerospace/high strength applications was $103 million, a 25% increase, after adjusting for an incremental $8 million of alloyed metal cost, on a 28% increase in shipments over the prior year quarter. The improvement in shipments reflected improving demand for commercial aerospace and strong plate shipments following the planned stretcher outage at the Company's Trentwood facility in the third quarter of 2022.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Conversion revenue for packaging applications was $134 million, a 2% increase, after adjusting for an incremental $23 million of alloyed metal cost, on a 16% decrease in shipments over the prior year quarter. The decline in shipments primarily reflects the impact of the force majeure declared during the third quarter of 2022 in addition to some destocking in the beverage can market.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Conversion revenue for general engineering applications was $92 million, a 26% increase, after adjusting for an incremental $4 million of alloyed metal cost, on a 7% decrease in shipments due to normal seasonality and destocking at service centers for the Company's extruded products.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Conversion revenue for automotive extrusions was $25 million, a 10% increase, after adjusting for an incremental $2 million of alloyed metal cost, on a 6% increase in shipments primarily reflecting improved pricing.

Reported net loss for the fourth quarter 2022 was $26 million, or $1.66 loss per diluted share, compared to net income and net income per diluted share of $2 million and $0.11, respectively, in the prior year period. Excluding the impact of pre-tax, non-run-rate items of $25 million, adjusted net loss was $7 million for the fourth quarter 2022, compared to adjusted net income of $5 million in the prior year period. Adjusted loss per diluted share was $0.45 for the fourth quarter 2022, compared to adjusted income per diluted share of $0.33 for the fourth quarter 2021.

Adjusted EBITDA of $30 million in the fourth quarter 2022 decreased $19 million compared to the prior year period. In addition to higher inflationary manufacturing cost, the fourth quarter of 2022 was impacted by $19 million of incremental cost driven by an inventory imbalance due to previous quarter supply chain disruptions and unrecovered alloy cost. Adjusted EBITDA as a percentage of conversion revenue was 8.4% in the fourth quarter 2022.

------

**Full Year 2022 Financial Results**

Net sales for the full year 2022 were $3.4 billion compared to $2.6 billion in the prior year period, reflecting a 12% increase in shipments and a 17% increase in average selling price per pound. The increase in average selling price reflected an approximately 11% increase in conversion revenue per pound and a 21% increase in underlying contained metal costs.

Conversion revenue for the full year 2022 was $1.4 billion. The impact of the aforementioned change to include all alloyed metal cost within Hedged Cost of Alloyed Metal in comparison to the Company's historical presentation resulted in a reduction of approximately $112 million in conversion revenue for 2022.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Conversion revenue for the Company's aerospace/high strength applications was $356 million, a 13% increase, after adjusting for an incremental $32 million of alloyed metal cost, on a 15% increase in shipments over 2021. The improvement in shipments reflected improving demand for commercial aerospace and continuing strong demand for business jet and defense applications.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Conversion revenue for packaging applications was $555 million, a 42% increase, after adjusting for an incremental $49 million of alloyed metal cost, on a 21% increase in shipments over 2021. Packaging shipments in 2021 reflect only nine months of activity as the acquisition of Warrick closed on March 31, 2021. In addition, shipments in 2022 were negatively impacted by the force majeure declared during the third quarter of 2022.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Conversion revenue for general engineering applications was $367 million, a 23% increase, after adjusting for an incremental $22 million of alloyed metal cost, on a 2% increase in shipments over 2021. Conversion revenue was supported by improved pricing which was partially offset by service center destocking for the Company's extruded products and the impact from the planned stretcher outage at the Company's Trentwood facility in the third quarter of 2022.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Conversion revenue for automotive extrusions was $96 million, relatively consistent with 2021, after adjusting for an incremental $7 million of alloyed metal cost, on a 3% increase in shipments, primarily reflecting improved pricing and mix as market demand remained stable amid persistent industry supply chain issues.

Reported net loss for the full year 2022 was $30 million, or $1.86 loss per diluted share, compared to a net loss and loss per diluted share of $19 million and $1.17, respectively, for the prior year period. Excluding the impact of pre-tax, non-run-rate items of $31 million, adjusted net loss was $2 million for the full year 2022, compared to adjusted net income of $33 million for the prior year period. Adjusted loss per diluted share was $0.14 for the full year 2022, compared to adjusted income per diluted share of $2.03 for the prior year period.

Adjusted EBITDA of $142 million in the full year 2022 decreased $43 million compared to the prior year period. The decline predominantly reflected significant supply chain issues specifically related to magnesium and hot metal supply at the Company's Warrick operation and reduced packaging and plate shipments in the third quarter 2022, due to the magnesium related force majeure coupled with the planned outage at its Trentwood operation. In addition, higher inflationary driven costs during the year, which the Company is aggressively working to offset through pricing actions, cost reduction efforts and efficiency improvement projects, further affected results. Adjusted EBITDA as a percentage of conversion revenue was approximately 10.3% in the full year 2022.

------

**Cash Flow and Liquidity**

Adjusted EBITDA of $142 million reported in the full year 2022 and cash on hand funded approximately $170 million of working capital requirements, $143 million of capital investments, $46 million of interest payments, $50 million of cash returned to shareholders through quarterly dividends and $6 million of cash taxes.

As of December 31, 2022, the Company had cash and cash equivalents of approximately $57 million and borrowing availability under the Company's revolving credit facility of approximately $558 million providing total liquidity of $615 million. There were no borrowings under the revolving credit facility during the quarter.

On January 12, 2023, the Company's Board of Directors declared a quarterly cash dividend of $0.77 per share which was paid on February 15, 2023 to stockholders of record as of the close of business on January 25, 2023.

**2023 Outlook**

The Company remains well positioned to navigate the current demand environment prevailing in its end markets in 2023. The Company expects demand in commercial aerospace to continue to strengthen throughout 2023 towards pre-pandemic levels with both business jet and defense remaining strong. In packaging, the Company expects its operations will return to more normalized levels in 2023 now that the most significant supply chain issues have been resolved, despite continuing impacts from higher metal costs and a lag in passing through certain costs. General Engineering demand is expected to soften for plate and rod & bar products on stable pricing levels as distributors destock inventories after taking advantage of lower metal prices in the second half of 2022. In the Automotive market, the Company does not expect a meaningful recovery until mid-to late 2023.

The Company is cautiously optimistic its consolidated adjusted EBITDA and adjusted EBITDA margin will begin to strengthen in 2023 as it returns to more normalized costs, improved efficiencies and continued commercial actions. For the first quarter 2023, the Company expects its consolidated adjusted EBITDA margin to improve by approximately 200 basis points from the fourth quarter 2022. Given continued strong inflationary pressures, ongoing macroeconomic uncertainty and recessionary concerns, the Company will not be providing an outlook for its full year 2023 consolidated adjusted EBITDA.

The Company's capital investment plans remain focused on supporting demand growth through capacity expansion, sustaining its operations, enhancing product quality and increasing operating efficiencies. The Company anticipates total capital investments in 2023 will be in the range of $170 million to $190 million, of which approximately 60% will be focused on growth initiatives, primarily reflecting investments in the new roll coat line at the Warrick facility.

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.

<sup>4.</sup>Other operating NRR items primarily represent the impact of adjustments to environmental expenses and net periodic post retirement service cost relating to Salaried VEBA.

<sup>5.</sup>Adjusted EBITDA = Consolidated operating income, excluding operating NRR items, plus Depreciation and amortization.

<sup>6.</sup>Non-operating NRR items represents the impact of non-cash net periodic benefit cost related to the Salaried VEBA excluding service cost and debt refinancing charges.

<sup>7.</sup>Diluted shares for EPS are calculated using the treasury stock method and were excluded from the computations in periods of net loss per share as their inclusion would have been anti-dilutive.
