Business Overview

Kaiser Aluminum Corporation, a Delaware corporation, manufactures and sells semi-fabricated specialty aluminum mill products for the following 

end market applications: (i) aerospace and high strength (“Aero/HS products”); (ii) beverage and food packaging products (“Packaging”); (iii) general 
engineering (“GE products”); (iv) automotive (“Automotive Extrusions”); and (v) other industrial (“Other products”). Our fabricated aluminum mill 
products include flat-rolled (plate, sheet and coil), extruded (rod, bar, hollows and shapes), drawn (rod, bar, pipe, tube and wire) and certain cast aluminum 
products. The sophistication of our products is due to the metallurgy and physical properties of the metal and the special characteristics that are required for 
particular end uses. We strategically choose to serve technically challenging applications for which we can deploy our core metallurgical and process 
technology capabilities to produce highly engineered mill products with differentiated characteristics that present opportunities for us 

3

 
to receive premium pricing and to create long-term profitable growth. A fundamental part of our business model is to remain neutral to the impact from 
fluctuations in the market price for aluminum and certain alloys, thereby earning profit predominately from the conversion of aluminum into semi-
fabricated mill products. We refer to this as “metal price neutrality.” See “Pricing, Metal Price Risk Management and Hedging” section below for more 
details. 

With respect to the global market for flat-rolled aluminum mill products, our focus is on heat treat plate and sheet for applications that require higher 

strength and other desired product attributes that cannot be achieved by common alloy rolled products. The primary end market applications of flat-rolled 
heat treat plate and sheet are Aero/HS products (which we sell globally) and GE products (which we predominantly sell within North America). On March 
31, 2021, with the completion of our acquisition of Alcoa Warrick LLC and certain assets comprising the aluminum casting and rolling mill facility located 
in Warrick County, Indiana (collectively, “Warrick”), we expanded our flat‑rolled aluminum products to include bare and coated aluminum coil for can 
stock applications in the beverage and food packaging industry in North America. Our Packaging products require demanding attributes and can be further 
processed to include coating and slitting depending on customer specifications.

Similarly, in the areas of extruded and drawn aluminum mill products, our focus is on Aero/HS products, GE products and Automotive Extrusions 

for demanding applications that require high strength, machinability or other specific properties where we can create and maintain a defensible competitive 
position because of our technical expertise, strong production capability and high product quality. We primarily serve North American demand for extruded 
and drawn aluminum mill products.

Our rolling mill in Spokane, Washington (“Trentwood”) produces heat treat plate and sheet for aerospace and general engineering end market 
applications and our Warrick facility produces bare and coated aluminum coil used for can stock applications in the beverage and food packaging industry. 
Our 11 extrusion/drawing facilities, 10 of which are in the United States and one of which is in Canada, serve aerospace, general engineering or automotive 
applications. Our facility located in Columbia, New Jersey focuses on multi-material advanced manufacturing methods and techniques which include 
multi-axis computer numerical control (“CNC”) machining, additive manufacturing (“3D Printing”), welding and fabrication for demanding aerospace and 
defense, high tech and general industrial and automotive applications. In 2022, our consolidated Net sales totaled $3,427.9 million on 1,254.2 million 
pounds shipped from our facilities.

We purchase primary, rolling ingot and scrap, or recycled, aluminum, our main raw material, and alloys at prices that fluctuate on a monthly basis, 
and our pricing policies generally allow us to pass the underlying index cost (see “Raw Materials” section below) of aluminum and certain alloys through 
to our customers so that we remain neutral to metal pricing. However, for some of our higher margin products sold on a spot basis, competitive dynamics 
may limit the amount and/or delay the timing of selling price increases to recover our increased aluminum and alloy costs, resulting in a lag up to several 
months during which we may be exposed to metal price risk. As a result, we can experience an adverse impact when aluminum and alloy prices increase 
and a favorable impact to us when aluminum and alloy prices decline, as we and our competitors tend to defer adjusting pricing unless market dynamics 
require such in a declining metal cost environment. We may also enter into firm-price customer sales agreements that specify a firm underlying metal price 
plus a conversion price. Spot sales with lagged aluminum and alloy price pass through and firm-price sales agreements create price exposure for us, which 
we mitigate through hedging and related programs with an objective to remain metal price neutral. Additionally, we have certain contracts that may adjust 
certain alloy prices for a forward period based on an average prior period cost for such alloys. As a result, until the selling price resets, we can experience 
an adverse impact when alloy prices increase and a favorable impact when alloy prices decrease. 

We further strive to enhance our margins through the efficient use of scrap or recycled aluminum. As scrap aluminum is usually purchased at a 

discount to the index price of aluminum at which we sell at, we can generate additional margins by increasing our utilization of scrap. However, as scrap 
aluminum availability and the discount to the index price at which it is sold is subject to market dynamics, in periods of lower availability, we may 
experience adverse impacts to our results and favorable impacts when scrap is more readily available. Furthermore, due to manufacturing requirements, 
supply chain disruptions or rapid changes in market demands for our products, we may not be able to utilize scrap efficiently, thereby causing an adverse 
impact to our margins, which we refer to as an inventory imbalance. 

We have long-standing relationships with our customers, which consist primarily of blue-chip companies, including leading aerospace and 

automotive manufacturers, tier one aerospace and automotive suppliers, beverage and food packaging manufacturers and metal service centers. 
Approximately 73% of our shipments is sold direct to manufacturers or tier one suppliers and approximately 27% is sold to metal service centers. In our 
served markets, we seek to be the supplier of choice by pursuing “Best in Class” customer satisfaction driven by quality, availability, service and delivery 
performance. We believe we differentiate our product portfolio through our broad product offering and our KaiserSelect® products, which are engineered 
and manufactured to deliver enhanced product characteristics with improved consistency, so as to result in better performance, lower waste and, in many 
cases, lower production cost for our customers.

4

 
We further strive to enhance the efficiency of product flow to our customers and our status as a supplier of choice by tightly integrating the 
management of our operations across multiple production facilities, product lines and target markets. Additionally, our strategy to be the supplier of choice 
and a low cost producer is enabled by a culture of continuous improvement that is facilitated by the Kaiser Production System (“KPS”), an integrated 
application of tools such as Lean Manufacturing, Six Sigma and Total Productive Manufacturing. Using KPS, we seek to continuously reduce our own 
manufacturing costs and eliminate waste throughout the value chain.

A key component of our business model is to maintain financial strength and flexibility through the business and economic cycles. We manage and 

monitor our financial strength through routine analysis of our liquidity position under scenarios of varying business and economic cycles. We also prioritize 
our capital allocation toward organic growth, such as efficiencies and quality in each of our end markets, while maintaining a strong balance sheet for 
inorganic opportunities and market growth potential and providing return to shareholders. Details of these capital projects are discussed in Part II, Item 7. 
“Management’s Discussion and Analysis of Financial Condition and Results of Operations” of this Report under the caption, “Liquidity and Capital 
Resources.”

Products

Overview

Our business focuses on producing rolled, extruded and drawn aluminum products used principally for aerospace and defense, aluminum beverage 

and food packaging, general engineering and automotive products that include consumer durables, electronics and products for electrical and machinery 
and equipment applications. Our engineers, metallurgists and sales personnel work collaboratively with our customers to help our customers design 
products for challenging applications where product performance is critical. Furthermore, our Centers for Excellence, dedicated research and development 
centers devoted to product performance enhancement and process development within our production operations, are focused on: (i) controlling the 
manufacturing process; (ii) maximizing the use of recycled aluminum; (iii) improving product quality; and (iv) ensuring consistency and enhanced product 
attributes. See “Selected Operational and Financial Information” within Part II, Item 7. “Management’s Discussion and Analysis of Financial Condition 
and Results of Operations” of this Report for selected shipment and sales information for our fabricated aluminum products by end market application.

We believe aluminum is highly sustainable because it is infinitely recyclable and the recycling process requires significantly less energy compared 
with the original mining and refining process. Our highly engineered solutions contribute to reduced carbon emissions by enabling improved performance 
of consumer products, light‑weighting in applications such as aircraft and transportation for fuel efficiency and increasing the use of recyclable aluminum 
beverage and food packaging. Overall, we remain focused on providing products that meet the needs of our customers for demanding applications while 
being part of the carbon solution for “Best in Class” customer satisfaction. 

Aero/HS Products. Our Aero/HS products include heat treat plate and sheet, hard alloy extruded shapes, cold finish rod and bar, seamless drawn tube 

and billet used for a wide variety of end uses in the global aerospace and defense industries. Typical applications are structural aircraft components that 
must perform consistently under extreme variations in temperature and pressure due to frequent take-offs, landings and changes in altitude. Required 
physical properties include high tensile strength, superior fatigue resistance and exceptional durability even in harsh environments. We use high-strength 
2000- and 7000-series alloys and apply a variety of thermal practices to manufacture our Aero/HS products to meet the demanding specifications required 
for such safety-critical applications. While competing materials such as titanium and composites have displaced aluminum for certain applications on 
several newer aircraft designs, aluminum continues to be the material used most extensively for structural aerospace and defense applications because it is 
light weight, can meet demanding performance requirements and is cost effective relative to other materials. 

Packaging. Our Packaging products consist of bare and coated 3000- and 5000-series alloy aluminum coil used in the beverage and food packaging 

industry, with applications that include coated food stock, coated end and tab stock, body stock and bottle stock. Our Warrick rolling mill is one of four 
major aluminum rolling mills currently dedicated to the packaging industry in North America, with one of the world’s largest ingot casting facilities, hot 
and cold rolling, coated finishing and slitting capacity. The Warrick rolling mill has a unique capability to produce high-margin coated packaging products 
representing approximately 64% of our total Packaging shipments. 

GE Products. Our broad portfolio of GE products consists primarily of 6000-series alloy plate, sheet, rod, bar, tube, wire and standard extruded 
shapes. The 6000-series alloy is an extremely versatile, medium-strength, heat treatable alloy that can be both extruded and rolled. Our GE products have a 
wide range of uses and applications, many of which involve further fabrication for numerous transportation and other industrial end market applications 
where machining of plate, rod and bar is intensive. For example, our GE products are used to produce armor for military vehicles, ordnances, 
manufacturing cells for semiconductor production, 

5

 
numerous electronic devices, after-market motor sport parts, tooling plate, parts for machinery and equipment, bolts, screws, nails and rivets. 

Automotive Extrusions. Automotive Extrusions consist of extruded aluminum products for many North American automotive applications. 
Examples of the variety of extruded products that we supply to the automotive industry include extruded products for the body-in-white structural 
components, crash management systems, anti-lock braking systems and drawn tube for drive shafts. For some Automotive Extrusions, we perform limited 
fabrication, including sawing and cutting to length. In recent years, automotive original equipment manufacturers (“OEMs”) and their suppliers have, at an 
increasing pace, been converting many automotive components that historically were made of steel to aluminum to decrease weight without sacrificing 
structural integrity and safety performance and thereby achieve greater fuel efficiency standards mandated by stringent United States’ Corporate Average 
Fuel Economy (“CAFE”) or equivalent state regulations. Our Automotive Extrusions are designed and produced to provide specific mechanical properties 
and performance attributes required in automotive applications across a broad mix of North American OEMs and automotive platforms. We believe that 
these attributes are not easily replicated by our competitors and are important to our customers, who are typically tier one automotive suppliers.

Other Products. Other products consist of rerolled, extruded, drawn and cast billet aluminum products for a variety of North American industrial 

end uses. We continue to exit these non-core applications and focus our resources and production capacity on strategic Aero/HS products, Packaging, GE 
products and Automotive Extrusions.

Markets

Sales, Marketing and Distribution

Industry sales for fabricated products fluctuate in response to competitive and market dynamics. Sales are made directly to customers by our sales 

personnel located in the United States, Canada, Western Europe and China and by independent sales agents in other regions of Asia, Latin America and the 
Middle East. Our sales and marketing efforts are focused on the markets for Aero/HS products, Packaging, GE products and Automotive Extrusions.

Aero/HS Products. We sell our Aero/HS products to metal service centers, as well as directly to aerospace manufacturers and tier one suppliers. 
Sales are made primarily under long-term agreements, but also on an order-by-order basis. We serve this market with a North American sales force focused 
on Aero/HS products and GE products and our sales personnel in Western Europe and China. Growth in demand for aerospace plate has exceeded demand 
growth for other forms of Aero/HS products, as aircraft manufacturers have migrated to monolithic component design, where a single piece of aluminum, 
usually a plate, is heavily machined to form a desired part rather than creating the same part by assembling sub-components made of aluminum sheet, 
extrusions or forgings that are affixed to one another using rivets, bolts or welds. Demand for our Aero/HS products is heavily impacted by commercial 
airframe build rates and, to a lesser degree, by defense related airframes and other products. In addition, unanticipated changes in build rates and mix of 
aircraft models being built can trigger restocking or destocking throughout the long aerospace supply chain, temporarily impacting demand. While 
commercial airframe build rates can be subject to certain short-terms events (see Part I, Item 1A. “Risk Factors” included in this Report), we believe the 
long-term demand for air travel and fuel efficiency will continue to drive long-term growth for our products.

Packaging. Our Packaging products are sold primarily to North American beverage can manufacturers and fillers and food packaging 

manufacturers. Sales are made primarily under long-term agreements by a North American direct sales force. Aluminum can stock demand is driven by the 
packaging industry’s shift towards environmentally sustainable materials due to the fact that aluminum is infinitely recyclable and has the highest consumer 
recycling rate among beverage containers. Major players have already transitioned some plastic bottled water and carbonated soft drink production to 
aluminum. We anticipate further growth will be underpinned by sustainability trends, the secular shift from plastic to aluminum and the fact that North 
American packaging capacity has been reallocated towards other end markets, including automotive and industrial.

GE Products. A majority of our GE products are sold to large metal service centers in North America on an order-by-order basis, with orders 

primarily consisting of standard catalog type items shipped with a relatively short lead-time. We service this market with a North American sales force 
focused on GE products and Aero/HS products. Demand for our GE products is closely related to the North America general industrial growth and the 
recent desire of many companies to lessen their risk of supply chain disruptions by reshoring suppliers and shortening the supply chain. Demand is also 
impacted by the destocking and restocking of inventory throughout the supply chain.

Automotive Extrusions. Our Automotive Extrusions are sold primarily to tier one automotive suppliers. Almost all sales are made under long-term 

agreements entered through direct channels using a North American direct sales force that works closely with our technical sales support organization. 
Demand for Automotive Extrusions is determined based upon automotive build rates in North 

6

 
America and aluminum content. We believe fuel efficiency standards, along with consumer preference for larger vehicles and the growing conversion to 
electric vehicles, will continue to drive growth in demand for aluminum extruded components in passenger vehicles as a replacement for the heavier weight 
of steel components. 

Customers

In 2022, we had approximately 570 customers, including key customers such as Reliance Steel & Aluminum Co. (“Reliance”) and Silgan 

Containers Corporation (“Silgan”). While the loss of either of these customers could have a material adverse effect on us, we believe that our long-standing 
relationship with each is good and that the risk of losing either customer is remote. See Note 17 of Notes to Consolidated Financial Statements included in 
this Report for information about our significant concentrations.

Competition

The fabricated aluminum industry is highly competitive. We seek to further differentiate ourselves from our competitors through our ongoing 
investments to continuously improve the quality and machinability of our products, manufacture and deliver unique product attributes (KaiserSelect®) and 
provide a broad product offering while maintaining a strong customer focus to achieve “Best in Class” status in our markets.

Our primary competitors in the global market for Aero/HS products are Arconic, Inc., Constellium N.V. and Novelis Inc. In North America, our 

primary competitors for Packaging are Arconic, Inc., Constellium N.V., Novelis, Inc. and Tri-Arrows Aluminum, Inc. In serving our North American 
customers for both GE products and Automotive Extrusions, our primary competitors are Arconic, Inc. and Norsk Hydro ASA, and for certain of these 
products, we also compete with smaller, regional participants. In North America, we also compete with general engineering heat treat plate products 
imported from South Africa, Europe and China. Some of our competitors are substantially larger, have greater financial resources and may have other 
strategic advantages. 

Because many of our products are used in safety critical applications, our customers have demanding standards for product quality and consistency 

that make it difficult to become a qualified supplier. Suppliers must pass a rigorous qualification process to sell to both airframe and automotive 
manufacturers and must also make significant investments in infrastructure and specialized equipment to supply products for these high strength 
applications. Further, sophisticated manufacturing processes make it difficult to become a qualified supplier, even with proper equipment. For example, 
producing heat treat plate and sheet products, particularly for aerospace applications, requires technological expertise that only a few companies have 
developed through significant investment in research and development and decades of operating experience. To be a supplier in the packaging market, 
demanding standards are also required. Producing coated end, tab and body stock for the can market requires the development of alloys and application of 
coatings that must pass stringent customer qualifications and be compliant with Food and Drug Administration (“FDA”) regulations. Our experienced and 
dedicated research and development team, combined with our Customer Service group, coordinate with coating suppliers, manufacturing operations and 
our customers to create these alloy and coating systems.

Research and Development

Our products are differentiated based on the metallurgy and physical properties of the metal and special characteristics that are required for 

particular end uses. A significant amount of our research and development is devoted to product and process development within our production 
operations, and is largely focused on controlling the manufacturing process to improve product quality, ensure consistency and enhance one or more 
specific product attributes. This has resulted in the creation and delivery of our highly differentiated KaiserSelect® products.

We operate four research and development centers. Our Rolling and Heat Treat Center and our Metallurgical Analysis Center are both located at our 
Trentwood facility. The Rolling and Heat Treat Center has complete hot rolling, cold rolling and heat treat capabilities to simulate, in small lots, processing 
of flat-rolled products for process and product development on an experimental scale. The Metallurgical Analysis Center consists of a full metallographic 
laboratory and a scanning electron microscope to support research and development programs as well as respond to plant technical service requests. The 
third center, our Solidification and Casting Center, is located in Newark, Ohio (“Newark”), and has a developmental casting unit capable of casting billets 
and ingots for extrusion and rolling experiments. The casting unit is also capable of casting full size billets and ingots for processing on the production 
extrusion presses and rolling mills. Our fourth center, located in New Kensington, Pennsylvania, is focused on the forming and coating of our packaging 
products and has the capability on laboratory-scaled equipment to produce beverage end and food cans enabling the evaluation of new coatings and 
processes for packaging products. In addition, our packaging research and development center utilizes a scanning electron microscope along with FDA 
analytical tools to provide technical expertise to our Warrick facility and our packaging customers.

7

 
Our Imperial Machine & Tool Co. (“IMT”) subsidiary, located in Columbia, New Jersey, provides us with significant technology and intellectual 

property that complements our metallurgical and application engineering expertise to further advance our capability to deliver highly engineered solutions 
for our customers. IMT’s multi-material expertise in aluminum, titanium, tantalum, molybdenum, nickel alloys, tungsten, cobalt chromium and stainless 
steel offers a differentiated approach by combining traditional machining know-how and related technical capabilities with additive manufacturing 
expertise to drive innovative solutions over the longer term.

We hold numerous patents, trademarks, trade secrets and copyrights that relate to the design, use and marketing of products. We consider this 

intellectual property to be important, but no single property is material to the overall conduct of our business.

Resources

Manufacturing Processes

We use two main processes, flat rolling and extrusion/drawing, to produce our fabricated products using a cast of alloyed prime and recycled 

aluminum in the desired forms and dimensions and with the desired physical properties. Both processes start by heating an aluminum rolling ingot or 
extrusion billet to an elevated temperature at which the metal is malleable and then applying pressure in a manner that both forces the metal into a desired 
shape and begins the “working” of the metal to enhance its strength and related properties.

Flat Rolling. Our manufacturing process for aluminum flat-rolled products uses ingot, a large rectangular slab of aluminum, as the starter material. 

The ingot is processed through a series of rolling operations that can be done at elevated (hot) or room (cold) temperatures. Finishing steps may include 
heat treatment, annealing, stretching, leveling, coating and slitting to achieve the desired metallurgical, dimensional and/or performance characteristics. 
Aluminum flat-rolled products are manufactured in a variety of alloys, a range of tempers (hardness), gauges (thickness) and widths and various finishes. 
Flat-rolled aluminum semi‑finished products are classified as plate (0.250 inches or greater in thickness), sheet (0.249 inches down to 0.008 inches in 
thickness) or coil (0.249 inches down to 0.001 inches in thickness).

Extrusion/Drawing. Our extrusion process begins with a cast billet, which is an aluminum cylinder of varying length and diameter cut from a cast 
log. After heating the billet to make the metal malleable, it is placed into an extrusion press and squeezed (extruded) through a die that gives the material 
the desired two-dimensional cross section. The material can be quenched as it leaves the press, or processed through a post-extrusion heat treatment cycle, 
to control the material’s physical properties. The extrusion is straightened, typically by stretching, and then cut to length before being hardened in aging 
ovens. Drawing is a fabrication operation in which extruded tubes and rods are pulled through a die, or drawn. The primary purpose of drawing is to reduce 
the diameter and wall thickness while improving physical properties and dimensions. Material may go through multiple drawing steps to achieve the final 
dimensional specifications. Extruded and drawn semi-fabricated products are manufactured in a variety of alloys and a range of tempers.

Additionally, some of our locations have remelt and casting operations to produce the ingot or log for flat rolling or extrusion. To produce the ingot 

or log, we purchase primary aluminum, recycled scrap aluminum segregated by alloys and other metals (including, but not limited to, copper, zinc and 
magnesium) that are necessary to create various aluminum alloys. We also recycle internally generated scrap from our own manufacturing processes. 
Initially in solid form, aluminum is heated in a vessel to a temperature at which it melts. While in molten form, additional metals (aluminum alloyed scrap, 
alloy metals, primary aluminum or high purity aluminum) are introduced to achieve the proper mixture of chemical elements for a particular alloy. When 
the desired chemical composition of the molten metal has been achieved, it is poured through a mold in which the molten metal cools in a controlled 
manner and solidifies into a rolling ingot or extrusion log. The size of the mold determines the dimensions of the rolling ingot or extrusion log. Our casting 
operations at our facilities in Kalamazoo, Michigan; London, Ontario; Los Angeles, California; Newark, Ohio and Sherman, Texas produce extrusion log 
and cut billet for their operations and for our other facilities that do not have casting operations. Our Trentwood and Warrick facilities cast rolling ingot for 
their own consumption.

IMT is a leader in advanced manufacturing methods and techniques, which include multi-axis CNC machining, 3D Printing, welding and fabrication 

for aerospace and defense, high tech and general industrial and automotive applications.

Many of our facilities employ the same basic manufacturing process and produce the same types of products. We make a significant effort to tightly 

integrate the management of our multiple manufacturing locations, product lines and end market applications to most efficiently and effectively serve the 
needs of our customers. We centralize purchasing of our primary, rolling ingot and scrap, or recycled, aluminum requirements and related alloying agents in 
order to better manage price, credit and other benefits. We believe that integration of our operations allows us to capture efficiencies while allowing our 
facilities to remain highly focused on their specific processes and end market applications.

Raw Materials

To make our fabricated products, we purchase primary aluminum and scrap, or recycled, aluminum from third-party suppliers in varying 

percentages depending on various market factors, including price and availability. The price we pay for primary aluminum is typically based on the average 
Midwest Transaction Price (“Midwest Price”), which reflects the primary aluminum supply/demand dynamics in North America. The average Midwest 
Price is comprised of the average London Metal Exchange (“LME”) plus average Midwest premium. The average LME and the average Midwest premium 
for 2022, 2021 and 2020 were $1.23 + $0.30, $1.12 + $0.26 and $0.77 + $0.12, respectively. Scrap aluminum is typically purchased at a discount to the 
Midwest Price but can require additional processing.

In addition to selling fabricated aluminum products to third parties, certain of our production facilities supply log, billet or other intermediate 

material to certain of our other facilities for further value added conversion processing. As examples, our London, Ontario facility supplies billet to our 
Richmond, Virginia facility, and our Newark facility supplies log and billet to our Jackson, Tennessee facility.

Suppliers

We purchase raw materials from a wide array of vendors. In most instances, we have multiple vendors of raw materials to mitigate the risk of an 

interruption of supply should one of them underperform or discontinue operations. A number of our input materials are commodities, which are subject to 
market price fluctuations, which we strive to mitigate with our metal price neutrality and hedging programs. See Note 17 of Notes to Consolidated 
Financial Statements included in this Report for information about our significant concentrations. 

Pricing, Metal Price Risk Management and Hedging

As noted above, we purchase primary, rolling ingot and scrap, or recycled, aluminum, our principal raw material, on a floating price basis typically 

based on the average Midwest Price. Our pricing of fabricated aluminum products is generally intended to lock in a conversion margin (representing the 
value added from the fabrication process) and to pass aluminum and certain alloy price fluctuations through to our customers. In order to meet our 
objective to be metal price neutral, we manage the risk of fluctuations in the price of aluminum through our pricing policies and use of financial 
derivatives. Our three principal pricing mechanisms are as follows:

•

•

Spot price. Some of our customers for Aero/HS products and a majority of our customers for GE products pay a product price that 
incorporates the spot price of primary aluminum (Midwest Price) in effect at the time of shipment to a customer. Spot prices for these 
products change regularly based on competitive dynamics. Fluctuation in the underlying aluminum price is a significant factor influencing 
changes in competitive spot prices. Through spot pricing, we generally can pass aluminum price risk through to customers. For some of our 
higher margin products sold on a spot basis, however, the pass through of aluminum price movements can lag by several months (the timing 
of which depends in part on market conditions), with a favorable impact to us when aluminum prices decline and an adverse impact to us 
when aluminum prices increase. We, from time to time, enter into hedging transactions with third parties to minimize the impact to us of 
aluminum price swings for these higher margin products.

Index-based price. The pricing structure of our typical aerospace and automotive contracts calls for our customer to pay a product price that 
incorporates a monthly index-based price for primary aluminum, such as the average Midwest Price for primary aluminum. Index-based 
pricing typically allows us to pass aluminum price risk through to the customer and applies to the majority of our Aero/HS products and 
Packaging sales and virtually all of our Automotive Extrusions sales.

•

Firm-price. Some of our customers who commit to volumes and timing of delivery pay a firm-price, creating aluminum price risk that we 
must hedge. We are able to limit exposure to aluminum price risks created by firm-price customer sales contracts by using third-party 
hedging instruments. Total fabricated product shipments for which we were subject to price risk were, in millions of pounds, 271.9, 187.2 
and 127.6 during 2022, 2021 and 2020, respectively. The growth in firm price contracts was primarily driven by the inclusion of Packaging 
beginning with our Warrick acquisition on March 31, 2021.

In addition to the aluminum pricing mechanisms described above, we also strive to pass through the cost of certain alloys through either pricing 
adders or surcharge mechanisms. In some cases, the passing through of this alloy cost can lag the actual alloy cost, the timing of which is dependent on 
market conditions and customer agreements, with a favorable impact to us when alloy price declines and an adverse impact to us when alloy price 
increases. As with aluminum, we, from time to time, enter into either hedging transactions with third parties or firm price physical contracts to minimize 
the impact to us of alloy price fluctuations.

9

 
All metal procurement and hedging activities are managed centrally to minimize transaction costs, monitor consolidated net exposures and respond 
promptly to changes in market factors. Hedging activities are conducted in compliance with a policy approved by our Board of Directors and administered 
by our hedging committee (members of which include our principal executive officer, principal financial officer and principal accounting officer).

Seasonality

Under normal operating and economic conditions, we generally have immaterial fluctuations in our overall portfolio quarter‑over‑quarter results. 

Within our individual end markets, our Packaging shipments are generally weighted towards the second half of the year as compared to the first half while 
our Aero/HS products, GE products and Automotive Extrusions shipments are generally weighted slightly more toward the first half of the year as 
compared to the second half. This fluctuation in shipments is usually driven by lower demand during summer vacation and year-end holiday shut downs 
and year-end inventory rebalancing by our end customers. During these periods of lower demand we generally perform planned major maintenance at our 
facilities, which can affect cost and operating results. 

Government Regulation

Our operations are subject to numerous federal, state and local employment, import/export, reporting, environmental, health and safety laws and 

regulations. While we are subject to a wide variety of government regulations, generally those most impactful to our results of operations and capital 
expenditures are the environmental laws and regulations that impose limitations on the discharge of hazardous materials and pollutants and establish 
standards for the handling, transportation, distribution, treatment, storage and disposal of hazardous materials and solid and hazardous wastes. These 
regulations may require the investigation, assessment, cleanup or monitoring of, or compensation for, environmental impacts, including natural resource 
damages. We continually monitor our operations with respect to potential environmental issues, including changes in legal requirements and remediation 
technologies. We have established procedures for regularly evaluating environmental loss contingencies. Our environmental accruals represent our 
undiscounted estimate of costs reasonably expected to be incurred based on presently enacted laws and regulations, existing requirements, currently 
available facts, existing technology and our assessment of the likely remediation actions to be taken. See Note 10 of Notes to Consolidated Financial 
Statements included in this Report.

The U.S. Environmental Protection Agency (“USEPA”) issued an Endangerment Finding under the Clean Air Act, determining that emissions of 

carbon dioxide, methane and four other greenhouse gases (“GHGs”) threaten the public health and welfare of current and future generations. We have 
invested and continue to invest in our manufacturing operations in order to reduce our GHG emissions. The GHG intensity of our products is reduced 
through: (i) increasing manufacturing efficiencies; (ii) using clean and reliable energy; (iii) using recycled and run-around scrap; and (iv) purchasing low 
carbon prime. 

Government Contracts

We are one of the few remaining United States based aluminum semi-fabricated producers that supply the American defense industry. Although our 
products are used in a wide variety of military applications, including military aircraft, armored vehicles and ordnance, these products are typically sourced 
from us by a number of service centers and machine shops that are suppliers to the defense industry. As we generally sell to the chain of suppliers who 
either subcontract with direct contractors or directly contract with the government, we do not have significant direct government agreements.

Human Capital

At December 31, 2022, we employed approximately 4,000 people, of which approximately 3,920 were employed in our manufacturing, sales and 

support office locations and approximately 80 were employed in a corporate capacity. 

Governance and Culture

Our talented workforce is a key factor underlying our success. We strive to be the employer of choice by providing equal employment and a 
non‑discriminatory workplace, protecting the health and safety of our employees, providing training programs and maintaining a positive and constructive 
relationship with labor unions of which our employees are members. Our values support and serve as the foundation for our strategic initiatives and are 
intended to reflect the company’s “tone at the top” which we believe sustains our culture; a culture that continues to drive our behavior. Additionally, the 
goal of being a valued corporate citizen guides our environmental, social and governance decisions. We are, as a result, committed to being socially 
responsible and active members of our industry and the communities in which we operate and our employees and their families live.

10

 
Consistent with our corporate values, we promote fair business practices and a culture of accountability, responsibility and ethical behavior through:

•

•

•

•

strong emphasis on the importance of integrity and competence;

conducting annual governance surveys to assess our culture and the effectiveness of our training;

adopting and enforcing our policies, including Corporate Governance Guidelines, Code of Business Conduct and Ethics, Human Rights Policy 
and Diversity, Equity and Inclusion Policy and compliance with applicable laws and regulations; and

encouraging the reporting of illegal or unethical behavior, including the use of In-Touch, a third party compliance feedback program.

We believe respecting human rights is a fundamental part of our values and corporate responsibility. We strive to respect and promote human rights 
in our relationships with our employees, suppliers, customers and stakeholders and are guided by the principles of the International Bill of Human Rights 
(the Universal Declaration of Human Rights and the two international covenants) and the International Labor Organization’s Declaration on the 
Fundamental Principles and Rights at Work. Our Human Rights Policy is communicated to our employees as part of their annual code of conduct training, 
and we expect our employees to uphold this policy.

Diversity, Equity, Inclusion and Belonging

We are committed to diversity, equity, inclusion and belonging and strive to be the preferred employer by, among other things: (i) attracting, 

developing and retaining the best people from all cultures and segments of the population based on ability; (ii) treating all employees with dignity and 
respect; (iii) providing an environment of diversity, inclusion, belonging, empowerment, responsibility and accountability; and (iv) offering competitive 
and equal pay and benefits that attract and retain employees. We focus on: (i) continuing to consider ethnic and gender diversity as we identify training 
cohorts and opportunities; (ii) leveraging the views and perspectives of our diverse employees and leaders; (iii) developing meaningful metrics and 
benchmarks by location and job function to measure the effectiveness of our efforts; (iv) fostering relationships with educational institutions, employment 
agencies and professional groups to expand the pool of potential candidates and employees to achieve a more diverse workforce; (v) focusing on diverse 
candidates for internships, entry-level positions and scholarships; and (vi) actively recruiting from military bases for military and veteran hiring. Our 
Human Rights Policy and Diversity, Equity and Inclusion Policy, which align with our corporate values and Code of Business Conduct and Ethics, are 
overseen by our Board of Directors and senior leadership team.

Labor Practices and Policies

Safety. We believe employee safety begins with a strong and consistent tone at the top through our executive leadership with oversight provided by 

our Corporate Health and Safety team, led by our Chief Administrative Officer and General Counsel. To help us achieve and maintain a strong safety 
culture, we have robust compliance and assessment programs such as annual safety planning, monthly safety calls, routine performance reviews against 
targets and routine audits. Additionally, we partner with the United Steelworkers and various industry groups, including the Aluminum Association, to 
share and identify best practices. We use both internal and external resources, including the American National Standards Institute (“ANSI”) and 
International Organization for Standardization (“ISO”), to assess our compliance with regulatory and internal standards, providing training, performing risk 
assessments, audits and loss control inspections and developing mitigation strategies with particular emphasis on risks with a greater potential for severe 
injury. We stress risk awareness and job safe practices and engage our employees in conversations about safety and safety training using a variety of 
communication channels, including one-on-one communications. 

We also believe that having a culture of health and safety involves every employee at every level throughout the organization assuming 

responsibility to guard against workplace injuries by recognizing risks and taking other actions to minimize injury risk and severity. Risk reduction is a key 
initiative at each of our facilities and part of our annual planning process and we are committed to nurturing a culture consistent with being a preferred 
employer. We monitor our progress through routine reviews of our safety process and performance. We utilize both leading and trailing indicators to 
monitor our progress. While trailing indicators, such as total case incident rate (“TCIR”), lost-time case incident rate (“LTIR”) and days away, restricted 
and transfer (“DART”) rate, help us monitor our safety performance, leading indicators, such as significant injury and fatality (“SIF”) potential and actual 
incident rate, near‑misses, timely correction action of internal and external audit findings, on-time safety plan execution information and safety culture risk, 
help us monitor and assess risks and the effectiveness of our safety plans and processes. Plant safety metrics are integrated into our monthly quality, 
production and financial reports and are reviewed by the senior leadership team every month. In addition, TCIR and LTIR safety modifiers are included in 
each of our short-term incentive compensation plans, including the corporate plan applicable to each of our executive officers and members of senior 
management.

11

 
Health. Over the years, we have implemented programs on a Company-wide basis to increase awareness of the importance of employee wellness. 
We have continued to introduce programs to educate and assist employees to make healthy lifestyle choices and have offered incentives and discounts to 
encourage participation across the organization, including:

•

•

•

•

•

•

annual onsite health biometric screenings;

on-site flu shots and the Coronavirus Disease 2019 (“COVID-19”) vaccination;

an employee assistance program, providing confidential assistance with healthcare issues and the healthcare system, including crisis and 
emergency help; 

a smoking/tobacco cessation program;

internal, as well as third-party, online wellness workshops, including workshops on nutrition and fitness; and

wellness coaching.

Labor Union Affiliations. We believe in freedom of association and respect our employees’ choice to be represented or not represented, by a union 
in accordance with the laws of the states and countries where we operate, without fear of reprisal, intimidation or harassment. Approximately 66% of our 
employees are represented by labor unions under labor contracts with varying durations and expiration dates. The following table shows each 
manufacturing location, the primary union affiliation, if any, and the expiration date for the current union contracts as of December 31, 2022. As indicated 
in the table, our union affiliations are with the United Steel, Paper and Forestry, Rubber, Manufacturing, Energy, Allied Industrial and Service Workers 
International Union, AFL-CIO, CLC (“USW”), International Association of Machinists (“IAM”) and International Brotherhood of Teamsters 
(“Teamsters”). See Note 17 of Notes to Consolidated Financial Statements included in this Report for additional information about concentration of labor 
subject to collective bargaining agreements.

Recruiting, Training, Development and Retention

Recruiting. We are committed to recruiting a workforce that reflects people from all cultures and segments of the population based on ability. Our 
initiatives, which go beyond legal compliance, include: (i) identifying and recruiting diverse talent, including military veterans; (ii) fostering relationships 
with universities, employment agencies and professional groups that work with more diverse populations; (iii) leveraging inclusive job-posting sites; and 
(iv) concentrating on diverse candidates for internships, entry‑level positions and scholarships. We have a well-established talent review process that 
includes operations and functional leaders that are key in the early identification of high performing and high potential employees. We also track and 
review the gender and ethnic diversity of job applicants and new hires to evaluate our efforts to continue to increase the diversity of our organization. The 
ESG committee of our board oversees, among other things, the succession planning for our executive officers and the leadership, progression and 
development of key employees. 

Training, Development and Retention. Kaiser Aluminum is committed to the development of our employees through a broad mix of internal and 

external program resources incorporating on-the-job training and development through the Kaiser Leadership Program, the Front Line Leader Development 
Program, the Kaiser Aluminum Women’s Leadership Program, Kaiser University, the Tuition Assistance Program and the Metallurgy Excellence and 
Technical Strength Program. We continue to expand our talent management initiatives to pursue the significant long-term potential for our continued 
success. Our success is dependent on the knowledge, skills and abilities of our current and future leaders and employees.

The Kaiser Leadership Program is a full year program that accelerates the readiness of key talent and combines personalized leadership development 

and Kaiser-management system focused curriculum with a unique opportunity to build relationships with an internal network of leaders across locations 
and functions. The mission of the Kaiser Leadership Program is to strengthen performance, develop bench strength and accelerate the readiness of key 
talent across our company. The program blends classroom, online modules and live web events using a cohort model to deliver a flexible, convenient 
learning environment and includes training and coaching conducted by Thayer Leadership at West Point.

The Front Line Leader Development Program is a six-month program that strengthens organizational performance through ethical, effective and 
sustaining tactical leadership for both new and experienced frontline supervisors. The program uses a cohort model to encourage collaboration and team-
building and to ensure accountability, facilitated group discussions and effective best practice sharing.

The Kaiser Aluminum Women's Leadership Program (“KWLP”) was launched in June 2022 and provides a female-focused professional 
development curriculum, mentorship and networking opportunities designed to elevate the visibility of women at Kaiser Aluminum, to increase female 
representation in all levels of leadership and to enhance the inclusion and sense of belonging for current and potential female leaders. Similar to the Kaiser 
Leadership Program, the KWLP uses in-person events, program meetings, self-directed learning and assignments, mentoring meetings and cohort 
collective meetings.

Kaiser University is our web-based learning and development platform offering a catalog of thousands of on-demand courses to employees across a 

broad range of topics including compliance, maintenance, health and safety, Lean Six Sigma, communication skills, business skills, computer skills, 
cybersecurity, discrimination and harassment prevention and our processes and policies.

The Tuition Assistance Program provides tuition reimbursement for salaried employees and certain represented employees as stipulated by the 
collective bargaining agreement. The mission of this program is to support our workforce in completing a degree that benefits both our employees and our 
company.

The Metallurgy Excellence and Technical Strength Program provides professional development for our talented metallurgical professionals in order 

to facilitate their ability to develop and implement process control systems and identify new technologies that can benefit the company. This program 
provides mentorship opportunities with company leaders and experts as well as participation in career enhancing training to ensure our competitive 
advantage.

Rewards

All of our employees, including hourly and salaried employees at our production facilities, participate in short-term incentive compensation plans, 
which are based on attainment of performance metrics that drive and support our “Best in Class” commitment. We also provide stock-based compensation 
to executive officers, members of senior management throughout the company and other key employees, as well as a deferred compensation plan for 
certain employees. All of our U.S. employees have access to 401(k) savings plans, depending on the terms of their employment, and salaried employees at 
our London, Ontario facility have access to a defined benefit pension plan with annual contributions based on each salaried employee’s age and years of 
service. Through the collective bargaining process, we contribute to four multi‑employer pension plans under the terms of certain collective bargaining 
agreements for a majority of our union-represented employees and certain union employees at our Warrick facility participate in a defined benefit pension 
plan, as well as a postretirement benefit plan relating to retiree medical and life insurance benefits. Additionally, certain hourly and salaried employees are 
also able to receive defined post-retirement health and welfare benefits through Voluntary Employee Beneficiary Associations.

Information Security

We employ information systems to support our business. As is the case for other manufacturing companies of comparable size and scope, we, from 

time to time, experience attempted cyber-attacks on our information system. We also face risks associated with other potential significant failures or 
disruptions of our information technology networks. We utilize a risk-based, multi-layered information security approach following the National Institute of 
Standards and Technology Cybersecurity Framework and have adopted and implemented an approach to identify and mitigate information security risks 
that we believe is commercially reasonable for manufacturing companies of our size and scope, including many of the best practices of the National 
Institute of Standards and Technology Cybersecurity Framework. 

Our information security performance and recent cybersecurity industry trends are reviewed by management, including our Chief Information 

Officer at least monthly and are reported to and reviewed by each of the audit committee and the full Board of Directors throughout the year (but no less 
than once a year). Our entire Board of Directors is responsible for overseeing management’s 

13

 
risk assessment and risk management processes designed to monitor and mitigate information security risks, including cyber risk and related insurance 
policies.

We regularly engage independent third parties to test our information security processes and systems as part of our overall enterprise risk 
management. We also conduct annual information security training to ensure employees are aware of information security risks and to enable them to take 
steps to mitigate those risks. As part of this program, we also take reasonable steps to ensure our executive management and employees, including any 
employee who may come into possession of confidential financial information, receive appropriate information security awareness training.

To date, no attempted cyber-attack or other attempted intrusion on our information technology networks has resulted in a material adverse impact 
on our operations or financial results, or in any penalties or settlements. In the event an attack or other intrusion were to be successful, we have a response 
team of internal and external resources engaged and prepared to respond. 

Item 1A. Risk Factors

In addition to the factors discussed elsewhere in this Report, the risks described below are those that we believe are material to our company. The 
occurrence of any of the events discussed below could significantly and adversely affect our business, prospects, financial position, results of operations 
and cash flows as well as the trading price of our securities.

RISKS RELATED TO CHANGES IN DEMAND FOR OUR PRODUCTS.

Recent macroeconomic factors including labor shortages, supply chain disruptions, inflation, recession risks and the COVID-19 pandemic have caused 
downturns  in  the  commercial  aerospace  industry  and  other  commercial  disruptions,  which  have  adversely  affected  our  business,  and  could  cause 
additional downturns in the automotive and ground transportation industries, which would further adversely affect our business.

We derive a significant portion of our revenue from products sold to the aerospace and automotive and ground transportation industries. 
Macroeconomic factors including, but not limited to: (i) labor shortages; (ii) disruptions to supply chains, such as the recent disruptions with our molten 
metal and magnesium supply chains; (iii) other interruptions of international and regional commerce; (iv) inflation; (v) higher interest rates; (vi) recession 
risks; and (vii) concerns regarding and measures implemented in response to pandemics of infectious disease, such as the COVID‑19 pandemic, have and 
could further cause changes in global travel and shipping patterns, negatively influencing demand for new commercial aircraft and other vehicles, resulting 
in cancellations or deferrals of orders and/or decreases in new deliveries. Moreover, because new automotive vehicle demand is tied closely to overall 
economic strength, economic uncertainty, increasing interest rates and/or increased unemployment could lead to weak demand for, or lower production of, 
new cars, light trucks, SUVs and heavy duty vehicles and trailers, which, in turn, could adversely affect demand for our products. Despite existing 
backlogs, additional adverse macroeconomic developments may lead to reduced demand for our products, which could adversely affect our financial 
position, results of operations and cash flows.

We operate in a highly competitive industry.

We compete with others in the fabricated products segment of the aluminum industry based upon quality, availability, price, customer service and 

delivery performance. Some of our competitors are substantially larger than we are, have greater financial resources than we do, operate more facilities 
than we do, are geographically closer to our customers than we are, employ more efficient or advanced technologies than we do or have other strategic 
advantages. Additionally, new parties may become capable of manufacturing similar products and qualifying them with our customers, which could lead to 
further competitive pressure. Competitors’ facilities located in certain other countries may have a manufacturing cost advantage compared to our facilities, 
which are located in the United States and Canada. Such foreign competitors may sell products similar to our products at lower prices as a result of having 
lower manufacturing costs or due to currency exchange rates that periodically favor foreign competition. Some foreign competitors may also dump their 
products in the United States and Canada in violation of existing trade laws. We may not be able to compete by differentiating ourselves based on the 
quality, availability and delivery of our products or our customer service. Additionally, we may not be able to reduce our cost structure and our selling 
prices to be competitive with others, and tariffs introduced to protect manufacturers in the United States and Canada from foreign price competition may 
not be fully effective. Increased competition could cause a reduction in demand for our products and our shipment volumes, our product pricing or both 

14

 
shipment volumes and product pricing, which could have an adverse effect on our financial position, results of operations and cash flows.

Reductions in demand for our products may be more severe than, and may occur prior to, reductions in demand for our customers’ products.

Most of our products undergo further fabrication by other parties before being deployed in their end uses. In particular, our Aero/HS products 

undergo numerous stages of further fabrication or assembly by a number of parties in the supply chain, often over the course of many months. The lead 
time from when we sell our Aero/HS product to when the finished product is installed on an aircraft often exceeds a year. Due to this long lead time, 
demand for our products may increase prior to demand for our customers’ products or may decrease when our customers experience or anticipate softening 
demand for their products. Our customers typically respond to reduced demand for their products by depleting their inventory until their inventory falls to a 
new desired level. This causes a greater reduction in demand for our products than our customers experience for their products. Further, the reduction in 
demand for our products can be exacerbated if our customers’ inventory levels had been higher than normal, if production is delayed for specific 
commercial airframe models, if our customers previously had purchased products from us at committed sales contract volumes that exceeded their actual 
need or for other reasons. The amplified reduction in demand for our products while our customers consume their inventory to meet their business needs 
(destocking) may adversely affect our financial position, results of operations and cash flows.

Our customers may reduce their demand for aluminum products in favor of alternative materials.

Our products compete with other materials for use in various customer applications. For instance, the commercial aerospace industry has used and 
continues to evaluate the further use of titanium, composites and carbon fiber materials as alternatives to aluminum to reduce aircraft weight and increase 
fuel efficiency. Additionally, while the automotive industry has continued to increase use of aluminum in vehicle production to reduce vehicle weight and 
increase fuel efficiency, manufacturers may revert to steel or other materials for certain applications and rely on improved drivetrain technology, more 
efficient engines, aerodynamics or other measures to achieve fuel efficiency goals. Finally, the packaging industry has used and continues to use steel, tin, 
plastics, glass and paperboard as alternatives to aluminum for packaging and delivery of food and beverages. The packaging industry is heavily influenced 
by cost and recyclability of the packaging material. The willingness of customers to use materials other than aluminum could adversely affect the demand 
for our products, particularly our Aero/HS products, Packaging and Automotive Extrusions, and thus could adversely affect our financial position, results 
of operations and cash flows.

Our customers may reduce their demand for our products if the government relaxes fuel efficiency standards or if oil prices remain low for a protracted
period of time.

Efficient use of fossil fuels partially drives demand for aluminum in transportation applications. The USEPA, other federal regulatory agencies and 
regulatory agencies of certain states have generally sought to limit growth of fossil fuel usage by establishing stricter fuel efficiency standards. In addition, 
newly elected and/or changing administrations could accelerate efforts to not only limit, but reduce, fossil fuel usage and carbon emissions beyond what 
may be technologically possible for certain products and manufacturing processes and revisit or reverse the environmental agendas of previous 
administrations with respect to previously established fuel efficiency standards. Additionally, in periods of lower oil prices, the economic benefits of 
replacing older aircraft and automobiles with more fuel-efficient models are less compelling. A relaxation of fuel efficiency standards by the regulatory 
agencies or an extended period of moderate oil prices could reduce demand for new more efficient aircraft and automobiles, which could adversely affect 
the demand for our products and have an adverse effect on our financial position, results of operations and cash flows.

The commercial aerospace industry is cyclical and downturns in the commercial aerospace industry could adversely affect our business.

We derive a significant portion of our revenue from products sold to the aerospace industry. Notwithstanding a secular growth trend spanning nearly 
two decades, the aerospace industry is highly cyclical. Numerous factors that influence demand for new commercial aircraft could result in cancellations or 
deferrals of aircraft orders and a global decrease in new commercial aircraft deliveries. These factors have included the impacts of the COVID-19 
pandemic on global travel and supply chains, but also include but are not limited to: (i) declines or reduced growth trends in global travel and airline 
passenger traffic; (ii) the rate of replacement of older aircraft with more fuel efficient aircraft; (iii) changing airline strategies affecting preferences for 
single-aisle aircraft models as opposed to twin-aisle or jumbo aircraft models; (iv) airline industry profitability; (v) the state of regional and global 
economies; (vi) concerns regarding terrorism or the threat of terrorism; (vii) concerns regarding new pandemics of infectious disease; and (viii) safety 
concerns with newly introduced and existing aircraft. Despite existing backlogs, adverse developments in any one or more of these influencing factors may 
lead to reduced demand for new aircraft that utilize our products, which could adversely affect our financial position, results of operations and cash flows.

Reductions in defense spending for aerospace and non-aerospace military applications could adversely affect demand for our products.

Our products are used in a wide variety of military applications, including military aircraft, armored vehicles and ordnance. Certain military 

programs are used by the U.S. armed forces, as well as by the defense forces of our allied foreign powers. Military programs that currently use or in the 
future could use our products may be subject to changes in military strategy and government priorities. Further, while many of the U.S. government 
programs span several years, they are often funded annually, and funding is generally subject to congressional appropriations. When U.S. and foreign allied 
governments are faced with competing national priorities, such as addressing financial or spending crises or public health emergencies, there can be 
significant pressure to reduce defense spending, which could reduce the demand for our products and adversely affect our financial position, results of 
operations and cash flows.

Downturns in the automotive and ground transportation industries could adversely affect our business.

The demand for our Automotive Extrusions and many of our general engineering and other industrial products is dependent on the production of 

cars, light trucks, SUVs and heavy duty vehicles and trailers in North America. The automotive industry is highly cyclical, as new vehicle demand is 
dependent on consumer spending and is tied closely to the overall strength of the North American economy. Even with the automotive industry’s growing 
use of aluminum to reduce vehicle weight, weak demand for, or lower production of, new cars, light trucks, SUVs and heavy duty vehicles and trailers 
could adversely affect the demand for our products and have an adverse effect on our financial position, results of operations and cash flows.

Changes in consumer demand for particular motor vehicles could adversely affect our business.

Sensitivity to fuel prices, an increased preference for environmentally friendly alternatives and other consumer preferences can influence consumer 

demand for motor vehicles that have a higher content of the aluminum Automotive Extrusions that we supply. The loss of business with respect to, or a lack 
of commercial success of, one or more particular vehicle models for which we are a significant supplier could have an adverse impact on our financial 
position, results of operations and cash flows.

Aluminum beverage and food packaging products are subject to competition from substitute products and decreases in demand, which could result in 
lower profits and reduced cash flows.

Aluminum coil produced for demanding end market applications in the beverage and food packaging industry in North America are subject to 

substantial competition from producers of alternative packaging made from glass, paper, flexible materials, plastic and organic or compostable materials, 
which may compare favorably to aluminum with respect to preservation of food and beverage quality and/or sustainability. Changes in the volume of sales 
by our customers in the food and beverage markets and preferences for products and packaging by consumers of prepackaged food and beverage cans may 
significantly influence our sales. Changes in packaging preferences by our customers may require us to re-tool manufacturing operations, which could 
require material expenditures. In addition, a decrease in the costs of, or a further increase in consumer demand for, alternative packaging could result in 
lower profits and reduced cash flows for us. For example, increases in the price of aluminum and decreases in the price of plastic resin, which is a 
petrochemical product and may fluctuate with prices in the oil and gas market, may increase substitution of plastic food and beverage containers for metal 
containers. Moreover, due to associated high percentage of fixed costs, we may be unable to maintain the gross margin of aluminum packaging products at 
past levels if we are not able to achieve high capacity utilization rates for our production equipment. In periods of low demand for aluminum packaging 
products or in situations where industry expansion created excess capacity, we may experience relatively low capacity utilization rates, which can lead to 
reduced margins during that period and can have an adverse effect on our business.

RISKS RELATED TO SALES.

We depend on a core group of significant customers.

In 2022, our five largest customers in total accounted for approximately 52% of our 2022 net sales. Most of these customers have one or more 
sizable sales agreements with us. If one or more of these customers experienced a prolonged period of adverse demand, depressed business activity or 
financial distress, if any of these customers breached or sought relief from its contractual obligations under its sales agreements with us or if any of these 
customer relationships otherwise ended or materially deteriorated and such lost business was not successfully replaced, our financial position, results of 
operations and cash flows could be adversely affected.

16

 
We experience fluctuation in certain costs that we cannot pass through to our customers and face pressure from our customers on pricing.

We are unable to pass fluctuations of certain costs through to our customers, including the cost of energy, certain raw materials, operating supplies 
and freight. Further, cost cutting initiatives that many of our customers have adopted generally result in downward pressure on pricing. If we are unable to 
generate sufficient productivity improvements and cost savings in the future to offset reductions in our selling prices and increases in our costs that we 
cannot pass through to our customers, our financial position, results of operations and cash flows could be adversely affected.

We are exposed to risks related to our receivables supply chain financing arrangements. 

We are party to several supply chain financing arrangements, in which we may sell certain of our customers’ trade accounts receivable without 

recourse to such customers’ financial institutions. To the extent that these arrangements are terminated, our financial condition, results of operations, cash 
flows and liquidity could be adversely affected by extended payment terms, delays or failures in collecting trade accounts receivables. The utility of certain 
supply chain financing arrangements also depends upon the Term Secured Overnight Financing Rate (“Term SOFR”), as it is a component of the discount 
rate applicable to certain arrangements. If the Term SOFR rate increases significantly or remains at an elevated level for a prolonged period of time, we 
may be negatively impacted as we may not be able to pass these added costs on to our customers, which could have a material and adverse effect upon our 
financial condition, results of operations and cash flows.

RISKS RELATED TO GEO-POLITICAL FACTORS.

Our industry is very sensitive to foreign economic, regulatory and political factors that may adversely affect our business.

We import primary aluminum and certain alloy metals from, and manufacture fabricated products used in, foreign countries. Our financial position, 

results of operations and cash flows could be adversely affected by numerous factors in the politically and economically diverse jurisdictions: (i) from 
which our input materials are sourced; (ii) in which we operate; (iii) in which our customers operate; or (iv) in which our products are consumed or further 
fabricated. Such factors include but are not limited to:

•

•

•

•

•

•

•

•

•

•

•

the adoption of tariffs, duties and other forms of taxation;

trade disputes;

the implementation of controls on prices, exports and/or imports, including quotas;

the implementation of other restrictions on supply chains in connection with global health pandemics;

the imposition of currency restrictions;

inflation relative to the United States and related fluctuations in currency and interest rates;

government regulation in the countries in which we operate, service customers or purchase raw materials;

acts or threats of war or terrorism;

sanctions, including those in response to acts or threats of war or terrorism;

civil unrest and labor problems; and

the nationalization or appropriation of rights or other assets.

RISKS RELATED TO PRODUCT AND MANUFACTURING.

We may experience difficulties in the launch or production ramp-up of new products which could adversely affect our business.

As we ramp up manufacturing processes for newly introduced products, we may experience difficulties, including manufacturing disruptions, delays 

or other complications, which could adversely impact our ability to serve our customers, our reputation, our costs of production and, ultimately, our 
financial position, results of operations and cash flows.

Unplanned events may interrupt our production operations, which may adversely affect our business.

The production of fabricated aluminum products is subject to unplanned events such as explosions, fires, inclement weather, natural disasters, 

accidents, equipment failures, labor disruptions, transportation interruptions, public utilities interruptions and supply interruptions. Operational 
interruptions could significantly curtail the production capacity of a facility for a period of time. We have redundant capacity and capability to produce 
many of our extruded products within our manufacturing platform to mitigate our 

17

 
business risk from such interruptions, but interruptions at our Trentwood facility where our production of plate and sheet is concentrated or at our Warrick 
facility where our production of packaging material is concentrated, could significantly compromise our ability to meet our customers’ needs. Delayed 
delivery of our products to customers who require on-time delivery from us may cause customers to purchase alternative products at a higher cost, 
reschedule their own production or incur other incremental costs. Customers may be able to pursue financial claims against us for their incremental costs, 
and we may incur costs to correct such problems in addition to any liability resulting from such claims. Interruptions may also harm our reputation among 
actual and potential customers, potentially resulting in a loss of business. To the extent these losses are not covered by insurance, our financial position, 
results of operations and cash flows could be adversely affected by such events.

We may face challenges to our intellectual property rights which could adversely affect our reputation, business and competitive position.

Our intellectual property plays an important role in maintaining our competitive position in a number of the markets that we serve. Our competitors 
may develop technologies that are similar or superior to our proprietary technologies or design around the patents we own or license. Despite our controls 
and safeguards, our technology may be misappropriated by our employees, our competitors or other third parties. The pursuit of remedies for any 
misappropriation of our intellectual property is expensive and the ultimate remedies may be deemed insufficient. Developments or assertions by or against 
us relating to intellectual property rights, and any inability to protect or enforce our rights sufficiently, could adversely affect our business and competitive 
position.

RISKS RELATED TO OUR STRATEGIC TRANSACTIONS AND INITIATIVES.

We may not be able to successfully implement our productivity enhancement and cost reduction initiatives that are necessary to offset competitive price 
pressure.

Over time, we have experienced pricing pressure on many of our products and anticipate continued pricing pressure in the future. Ongoing and 

heightened competitive price pressure makes it increasingly important for us to be a low cost producer. Although we have undertaken and expect to 
continue to undertake productivity enhancement and cost reduction initiatives, including significant investments in our facilities to improve our 
manufacturing efficiency, cost and product quality, we cannot make assurances that we will complete all of these initiatives, that we will fully realize the 
estimated cost savings from such activities, that short-to-medium term improvements from new efficiencies and lower cost structure achieved will become 
permanent or that we will be able to continue to reduce cost and increase productivity over the long term.

Our investment and other expansion projects may not be completed, start up as scheduled or deliver the expected capacity and other benefits.

Our ability to complete our investment and expansion projects and the timing and costs of doing so are subject to various risks associated with all 

major construction projects, many of which are beyond our control, including technical or mechanical problems and economic conditions. Additionally, the 
start-up of operations after such projects have been completed can be complicated and costly. If we are unable to fully complete these projects, if the actual 
costs for these projects exceed our expectations, if the start-up phase after completion is more complicated than anticipated or if the capacity and other 
benefits of these projects are less than anticipated, our financial position, results of operations and cash flows could be adversely affected.

We may not realize the benefits of the Warrick rolling mill acquisition.

Our acquisition of Warrick rolling mill in 2021 could disrupt our business and/or dilute or adversely affect the price of our common stock. Risks 

associated with the Warrick rolling mill acquisition may include:

•

•

•

•

•

•

•

diversion of management’s time and attention from our existing business;

challenges in managing the increased scope, geographic diversity and complexity of operations;

difficulties integrating the financial, technological and management standards, processes, procedures and controls of the acquired business 
with those of our existing operations;

liability for known or unknown environmental conditions or other contingent liabilities not covered by indemnification or insurance;

greater than anticipated expenditures required for compliance with environmental or other regulatory standards or for investments to improve 
operating results;

ability to renegotiate acquired customer contracts to pass through inflationary costs;

difficulties achieving anticipated operational improvements; and

18

 
•

incurrence of indebtedness to finance other acquisitions or capital expenditures relating to acquired assets in the future.

If we fail to successfully integrate the Warrick rolling mill, we may not realize the benefits expected from the transaction and/or it may have adverse 

effects on our financial position, results of operations and cash flows.

We are dependent upon Alcoa Corporation (“Alcoa”) for certain resources essential to the day-to-day operation of our business at Warrick.

We are dependent upon Alcoa for certain resources required for the day-to-day operation of our business at Warrick, which include molten 
aluminum and “support services” such as the provision of potable water, compressed air, laboratory services, electricity, steam and hot water. In order to 
transition Warrick from dependence upon the support services to independence as a facility with its own self-sufficient infrastructure, Alcoa has agreed to 
provide “transition services,” including providing infrastructure and equipment for the production of steam, hot water and compressed air and conveying 
the filtration plant currently utilized for the supply of potable water. In addition, Alcoa has agreed to pay for the development of infrastructure necessary for 
Warrick to obtain electricity from a third party power supplier, subject to certain conditions no later than June 30, 2024. A failure by Alcoa to provide 
molten aluminum and support services or transition services within the time frames and upon the terms agreed to, including quality and performance 
standards, could cause us to incur substantial costs to keep the Warrick rolling mill operational or result in the temporary or permanent shutdown of 
Warrick’s operations. In the event that production of Warrick is negatively impacted by Alcoa’s failure to provide molten aluminum, support or transition 
services, our operations, business, financial condition and results of operations could be adversely affected.

RISKS RELATED TO COMMODITY-RELATED PRICE FLUCTUATIONS.

Our business could be adversely affected by pricing and availability of primary aluminum.

Our largest inputs to produce fabricated aluminum products are primary aluminum and recycled scrap aluminum. Primary aluminum pricing 
fluctuates in response to global supply and demand and also reflects the impact of duties and tariffs imposed by the United States and certain other 
countries. The timing and magnitude of changes in market pricing for primary aluminum are largely unpredictable. Our pricing structures for fabricated 
aluminum products generally allow us to pass fluctuations in the price of primary aluminum through to our customers so that we can minimize our 
exposure to metal price risk. However, competitive dynamics for certain of our high margin products may limit the amount or delay the timing of selling 
price increases on our products to recover our increased aluminum costs, resulting in a time lag during which we may be partially exposed to metal price 
risk. If these events were to occur, they could have an adverse effect on our financial position, results of operations and cash flows. In addition, if the 
market price for primary aluminum were to remain high for an extended period of time, the corresponding increase in our selling price for our fabricated 
products may cause some of our customers to switch to other materials in lieu of our products, causing sales of our fabricated aluminum products to 
decrease, which could adversely affect our financial position, results of operations and cash flows.

Our business could be adversely affected by the pricing and availability of recycled scrap aluminum.

We can efficiently use certain forms of recycled scrap aluminum in lieu of primary aluminum and alloying metals in our operations because recycled 

scrap aluminum trades at a discount to primary aluminum. The size of the discount to primary aluminum depends on regional scrap aluminum supply and 
demand dynamics. Larger discounts, generally available in periods of ample regional scrap aluminum supply relative to demand, enhance the economic 
advantage to us of using recycled scrap aluminum in lieu of primary aluminum and alloying metals. The timing and magnitude of changes in scrap 
discounts relative to primary aluminum are largely unpredictable. If the availability of recycled scrap aluminum in our regional markets were to tighten, 
scrap discounts relative to primary aluminum could decline and the amount of recycled scrap aluminum we could procure for use in our operations could 
decline, either of which could have an adverse effect on our financial position, results of operations and cash flows. 

Our business could be adversely affected by the pricing and availability of alloying metals.

We use certain alloying metals, such as copper, zinc, magnesium and silicon, in our operations in order to achieve required performance properties 

in our products. The availability of these alloys in some cases has been and in the future may be restricted due to limited suppliers, government regulations, 
energy and supply chain disruptions and/or general demand dynamics. When sudden restrictions of these materials occur we have been and in the future 
may be subject to rapid price increases and limited supplies, either of which could have an adverse effect on our financial position, results of operations and 
cash flows. 

Reduced pricing for aluminum can reduce our borrowing availability and cause our liquidity to decline.

Lower aluminum prices reduce the market value of our inventory and generally cause a reduction in our accounts receivable as we pass through a 

lower underlying aluminum price to our customers. Because the amount we can borrow under our revolving credit 

19

 
facility with Wells Fargo Bank, National Association, as administrative agent, and the other financial institutions party thereto (“Revolving Credit 
Facility”) is determined by the value of our receivables and inventory, which serve as collateral for the facility, a reduction in aluminum prices can reduce 
our borrowing availability and our liquidity, which could have an adverse effect on our financial position, results of operations and cash flows.

Our hedging programs have been and could continue to be adversely impacted by fluctuations as a result of the impacts of supply chain disruptions, 
geopolitical activity and general economic conditions.

We use forward contracts to protect against fluctuations in commodity price and currency exchange rate risks. The effectiveness of these hedges 

depends, in part, on our ability to accurately forecast future product demand and related cash flow. Due to the impacts of supply chain disruptions, 
geopolitical activity, general economic conditions and other factors, our customers’ businesses are subject to many uncertainties and, as a result, we have 
experienced, and may continue to experience, unanticipated volatility in product demand and related cash flows. When we experience such volatility or are 
otherwise unable to make accurate predictions with respect to our forward swaps designated as cash flow or fair value hedges, such hedging activities may 
become ineffective. The early settlement, reclassification of cumulative losses and/or the periodic adjustment to fair value through Net (loss) income 
associated with ineffective hedging activities could have a material negative impact on our financial position, results of operations and cash flows.

Our hedging programs may limit the income and cash flows we would otherwise expect to receive if our hedging programs were not in place and may 
otherwise affect our business.

In the ordinary course of business, we enter into hedging transactions to limit our exposure to risks relating to changes in the market prices of 
primary aluminum, certain alloying metals, natural gas and electricity, as well as fluctuations in foreign currency exchange rates. To the extent that market 
prices or exchange rates at the expiration of these hedging transactions would have been more favorable to us than the fixed prices or rates established by 
these hedging transactions, our income and cash flows will be lower than they otherwise would have been. Our liquidity could also be adversely affected to 
the extent we incur margin calls from our hedging counterparties due to the market price of the underlying commodity or the foreign currency exchange 
rates deviating adversely from fixed, floor or ceiling prices or rates established by our outstanding hedging transactions. Our failure to satisfy certain 
covenants in the underlying hedging documents or the occurrence of an event of default thereunder could also trigger margin calls that could adversely 
impact our liquidity, financial position, results of operations and cash flows. Our hedging programs also expose us to the creditworthiness of our hedging 
counterparties, which is inherently difficult to assess and can change quickly and dramatically. Non-performance by a hedging counterparty could have an 
adverse effect on our financial position, results of operations and cash flows.

RISKS RELATED TO OUR INDEBTEDNESS.

Covenants and events of default in our debt instruments could limit our ability to undertake certain types of transactions and adversely affect our 
liquidity.

Our Revolving Credit Facility and the indentures governing our 4.625% Senior Notes due 2028 (“4.625% Senior Notes”) and 4.50% Senior Notes 

due 2031 (“4.50% Senior Notes”) contain a number of restrictive covenants that impose operating and financial restrictions on us and may limit our ability 
to engage in acts that may be in our long-term best interest, including restrictions on our ability to:

•

•

•

•

•

•

•

•

•

•

•

incur additional indebtedness and guarantee indebtedness; 

pay dividends or make other distributions or repurchase or redeem capital stock; 

prepay, redeem or repurchase certain debt; 

issue certain preferred stock or similar equity securities; 

make loans and investments;

sell assets; 

incur liens; 

enter into transactions with affiliates; 

alter the businesses we conduct; 

enter into agreements restricting our subsidiaries’ ability to pay dividends; and 

consolidate, merge or sell all or substantially all of our assets.

20

 
In addition, restrictive covenants in our Revolving Credit Facility require us in certain circumstances to maintain specified financial ratios and 
satisfy other financial condition tests. Our ability to meet those financial ratios and tests can be affected by events beyond our control and we may be 
unable to meet them.

A breach of the covenants or restrictions under our Revolving Credit Facility or under the indentures governing the 4.625% Senior Notes and 4.50% 

Senior Notes could result in an event of default under the applicable indebtedness. Such a default may allow the creditors to accelerate the related debt. A 
payment default or an acceleration following an event of default under our Revolving Credit Facility or our indentures for our 4.625% Senior Notes and 
4.50% Senior Notes could trigger an event of default under the other indebtedness obligation, as well as any other debt to which a cross-acceleration or 
cross-default provision applies, which could result in the principal of and the accrued and unpaid interest on all such debt becoming due and payable. In 
addition, an event of default under our Revolving Credit Facility could permit the lenders under our Revolving Credit Facility to terminate all commitments 
to extend further credit under that facility. Furthermore, if we were unable to repay any amounts due and payable under our Revolving Credit Facility, those 
lenders could proceed against the collateral granted to them to secure that indebtedness. In the event our lenders or noteholders accelerate the repayment of 
our borrowings, we and our subsidiaries may not have sufficient assets to repay that indebtedness.

As a result of these restrictions, we may be:

•

•

•

limited in how we conduct our business and grow in accordance with our strategy; 

unable to raise additional debt or equity financing to operate during general economic or business downturns; or 

unable to compete effectively or to take advantage of new business opportunities.

In addition, our financial results, our level of indebtedness and our credit ratings could adversely affect the availability and terms of any additional 

or replacement financing.

More detailed descriptions of our Revolving Credit Facility and the indentures governing our 4.625% Senior Notes and 4.50% Senior Notes are 

included in filings made by us with the SEC, along with the documents themselves, which provide the full text of these covenants.

Restrictive covenants in our debt instruments contain significant qualifications and exceptions.

While our Revolving Credit Facility and the indentures governing the 4.625% Senior Notes and 4.50% Senior Notes place limitations on our ability 
to pay dividends or make other distributions, repurchase or redeem capital stock, make loans and investments and incur additional indebtedness, investors 
should be aware that these limitations are subject to significant qualifications and exceptions. The aggregate amount of payments made or incremental debt 
incurred in compliance with these limitations could be substantial.

As indicated above, more detailed descriptions of our Revolving Credit Facility and the indentures governing our 4.625% Senior Notes and 4.50% 

Senior Notes are included in filings made by us with the SEC, along with the documents themselves, which provide the full text of these covenants.

Servicing our debt requires a significant amount of cash and we may not have sufficient cash flow from our business to pay our debt.

Our ability to make scheduled interest and principal payments on our debt obligations or to refinance such obligations depends on our financial 

condition and operating performance, which are subject to prevailing economic and competitive conditions and to certain financial, business, legislative, 
regulatory and other factors beyond our control. We may be unable to maintain a level of cash flows from operating activities sufficient to permit us to pay 
the interest, principal and premium, if any, on our indebtedness.

If our cash flows and capital resources are insufficient to fund our debt service obligations, we could face substantial liquidity problems and could 

be forced to reduce or delay investments and capital expenditures, dispose of material assets or operations, restructure or refinance our indebtedness or seek 
additional debt or equity capital. We may not be able to effect any such alternative measures, if necessary, on commercially reasonable terms or at all and, 
even if successful, those alternative actions may not allow us to meet our scheduled debt service obligations. Our Revolving Credit Facility and the 
indentures governing the 4.625% Senior Notes and 4.50% Senior Notes restrict our ability to dispose of assets and use the proceeds from those dispositions 
and may also restrict our ability to raise debt or certain forms of equity capital to be used to repay other indebtedness when it becomes due. We may not be 
able to consummate asset dispositions or to obtain proceeds in an amount sufficient to meet any debt service obligations then due.

21

 
If we cannot make scheduled payments on our debt, we will be in default and holders of the 4.625% Senior Notes and 4.50% Senior Notes could 

declare all outstanding principal and interest to be due and payable, the lenders under our Revolving Credit Facility could terminate their commitments to 
loan money, the lenders could foreclose against the assets securing their borrowings and we could be forced into bankruptcy or liquidation.

We are a holding company and depend on our subsidiaries for cash to meet our obligations and pay any dividends.

We are a holding company and conduct all of our operations through our subsidiaries, certain of which are not guarantors of our 4.625% Senior 

Notes, 4.50% Senior Notes or our Revolving Credit Facility. Accordingly, repayments of our 4.625% Senior Notes, 4.50% Senior Notes and amounts due 
under our Revolving Credit Facility are dependent on the generation of cash flow by our subsidiaries and their ability to make such cash available to us by 
dividend, loan, debt repayment or otherwise. Our subsidiaries that are not guarantors of our 4.625% Senior Notes, 4.50% Senior Notes or the Revolving 
Credit Facility have no obligation to pay amounts due on the 4.625% Senior Notes, 4.50% Senior Notes or the Revolving Credit Facility or to make funds 
available for that purpose. Our subsidiaries may not be able to, or may not be permitted to, make distributions to enable us to make payments in respect of 
our indebtedness. Each of our subsidiaries is a distinct legal entity and, under certain circumstances, legal and contractual restrictions may limit our ability 
to obtain cash from our subsidiaries. In the event that we do not receive distributions from our subsidiaries, we may be unable to make required interest and 
principal payments on the 4.625% Senior Notes, the 4.50% Senior Notes or our Revolving Credit Facility, or other indebtedness.

Our inability to receive distributions from our subsidiaries, otherwise generate sufficient cash flows to satisfy our debt obligations or refinance our 

indebtedness on commercially reasonable terms, or at all, would adversely affect our financial position and results of operations.

RISKS RELATED TO OUR COLLECTIVE BARGAINING AGREEMENTS.

Our failure to maintain satisfactory labor relations could adversely affect our business.

At December 31, 2022, approximately 66% of our employees were represented by labor unions under labor contracts with varying durations and 
expiration dates. Employees at our Trentwood and Newark, Ohio (“Newark”) facilities are represented by the USW under a single contract that extends 
through September 2025. The USW also represents employees at six other facilities, one of which has a contract expiring in 2023. As part of any labor 
negotiation, the future wages, healthcare benefits and excise taxes that may result therefrom, and other benefits that we agree to, could adversely affect our 
future financial position, results of operations and cash flows. In addition, negotiations could divert management attention, result in unsatisfactory terms 
and conditions, fail in coming to any agreement at all or result in strikes, work stoppages or other union-initiated work actions, any of which could have an 
adverse effect on our financial position, results of operations and cash flows. Moreover, the existence of labor agreements may not prevent such union-
initiated work actions.

Our participation in multi-employer union pension plans may have an adverse effect on our financial performance.

We participate in several multi-employer pension plans pursuant to our collective bargaining agreements. Our contribution amounts to these plans 
were established by collective bargaining and, along with benefit levels and related items, will be issues in our future collective bargaining negotiations. 
Based on the most recent information available to us, we believe some of these plans are underfunded and may require increased contributions from 
participating employers to fill the funding shortfall in the future. An employer that withdraws or partially withdraws from a multi-employer pension plan 
may incur a withdrawal liability for the portion of the plan’s underfunding that is allocable to the withdrawing employer under very complex actuarial and 
allocation rules. The failure of a withdrawing employer to fund these obligations can increase the burden of the remaining participating employers to make 
up the funding shortfall, which could have an adverse effect on our financial position, results of operations and cash flows. The increase or decrease in our 
contributions to these multi-employer pension plans will depend on our future collective bargaining, actions taken by trustees who manage the plans, 
actions of other participating employers, government regulations and the actual return on assets held in the plans, among other factors.

22

 
An adverse decline in the liability discount rate, lower-than-expected investment return on pension assets and other factors could affect our business, 
financial condition, results of operations or amount of pension funding contributions in future periods.

Our results of operations may be negatively affected by the amount of expense we record for our pension and other postretirement benefit plans, 
reductions in the fair value of plan assets and other factors. We calculate income or expense for our plans using actuarial valuations in accordance with 
accounting principles generally accepted in the United States of America (“GAAP”). 

These valuations reflect assumptions about financial market and other economic conditions, which may change based on changes in key economic 
indicators. The most significant year-end assumptions we use to estimate pension or other postretirement benefit income or expense for the following year 
are the discount rate applied to plan liabilities and the expected long-term rate of return on plan assets. In addition, we are required to make an annual 
measurement of plan assets and liabilities, which may result in a significant charge to stockholders’ equity. For more information, see Part II, Item 7. 
“Management’s Discussion and Analysis of Financial Condition” under caption “Critical Accounting Estimates and Policies – Pension and Other 
Postretirement Benefits” included in this Report, as well as Note 5 of Notes to Consolidated Financial Statements included in this Report. Although GAAP 
expense and pension funding contributions are impacted by different regulations and requirements, the key economic factors that affect GAAP expense 
would also likely affect the amount of cash we would contribute to the pension plans.

Potential pension contributions include both mandatory amounts required under federal law and discretionary contributions to improve the plans’ 
funded status. Higher than expected pension contributions due to a decline in the plans’ funded status as a result of declines in the discount rate or lower-
than-expected investment returns on plan assets could have a material negative effect on our cash flows. Adverse capital market conditions could result in 
reductions in the fair value of plan assets and increase our liabilities related to such plans, adversely affecting our liquidity and results of operations.

The USW has director nomination rights through which it may influence us, and interests of the USW may not align with our interests or the interests 
of our stockholders, debt holders and other stakeholders.

Pursuant to agreements we have with the USW, the USW has the right, subject to certain limitations, to nominate candidates which, if elected, 

would constitute 40% of our Board of Directors through December 31, 2025. As a result, the directors nominated by the USW have a significant voice in 
the decisions of our Board of Directors. It is possible that the USW may seek to extend the term of the agreement and its right to nominate board members 
beyond 2025.

RISKS RELATED TO ENVIRONMENTAL LAWS AND REGULATIONS AND ESG INITIATIVES.

Environmental compliance, cleanup and damage claims may decrease our cash flow and adversely affect our business.

We are subject to numerous environmental laws and regulations, including permitting and other administrative requirements, with respect to, among 
other things: (i) air and water emissions and discharges; (ii) the generation, storage, treatment, transportation and disposal of solid and hazardous materials; 
and (iii) the release of hazardous or toxic substances, pollutants and contaminants into the environment. In addition to environmental laws and regulations, 
environmental activists, lobbyists and consumers have targeted manufacturers for the purported impact of their operations on the environment. Compliance 
with existing and new environmental laws and standards or the implications of any actions by third parties are and may continue to be costly and, in some 
cases, unpredictable.

We have accrued and will accrue for costs that are reasonably expected to be incurred based on available information with respect to permits, fines, 

penalties and expenses for alleged breaches of, and compliance activities associated with, environmental laws and regulations in connection with our 
existing operations and investigations and environmental cleanup activities with respect to certain of our former operations. However, actual costs could 
exceed accrued amounts, perhaps significantly, and such expenditures could occur sooner than anticipated, which could adversely affect our financial 
position, results of operations and cash flows.

Additionally, we may be subject to new claims from governmental authorities or third parties related to alleged injuries to the environment, human 

health or natural resources, including claims with respect to waste disposal sites, the cleanup of sites currently or formerly used by us or exposure of 
individuals to hazardous materials. New laws or regulations or changes to existing laws and regulations may also be enacted that increase the cost or 
complexity of compliance. Costs related to any new investigation, cleanup or other remediation, fines or penalties, resolution of third-party claims or 
compliance with new or amended laws and regulations, including enhanced permitting requirements, may be significant and could have an adverse effect 
on our financial position, results of operations and cash flows.

23

 
Governmental regulation relating to greenhouse gas emissions may subject us to significant new costs and restrictions on our operations and could 
impact our supply chain and cost of material.

Laws enacted by governments, including the U.S. Congress, or policies of regulators, including the USEPA, could regulate greenhouse gas 
emissions through cap-and-trade systems, carbon taxes or other programs under which emitters would be required to buy allowances to offset emissions of 
greenhouse gas, pay carbon based taxes, make significant capital investments, alter manufacturing practices or curtail production. In addition, several 
states, including the state of Washington, in which we have manufacturing operations, have implemented and continue to consider various greenhouse gas 
regulation and reduction programs through legislative proposals, executive orders and ballot initiatives. Certain of our manufacturing plants use significant 
amounts of electricity and natural gas and certain of our plants emit amounts of greenhouse gas above certain minimum thresholds that have or may be 
imposed. While certain of our operations, including the melting of aluminum, require the use of natural gas to achieve the required temperatures, 
greenhouse gas regulations could restrict our access to natural gas and limit our ability to use natural gas and increase the price we pay for natural gas and 
electricity, any one of which could significantly increase our costs, reduce our competitiveness in the global economy or otherwise adversely affect our 
business, operations or financial results.

Furthermore, regulations or other targets for greenhouse gas emissions could impact the availability and price of energy and raw materials, which 

could ultimately lead to supply demand imbalances, higher costs and supply chain disruptions. Prolonged shortages or slowdowns could negatively impact 
our cost of goods and result in delays or non-delivery of shipments of our products. The future impact of these or other changes could be regulatory or 
voluntary and could impact our operations directly or indirectly through our customers or our supply chain. These potential impacts could have an adverse 
effect on our operations, financial position, results of operations and cash flows. 

Expectations relating to ESG considerations expose us to potential liabilities, increased costs, reputational harm and other adverse effects on our 
business.

Many governments, regulators, investors, employees, customers and other stakeholders are increasingly focused on ESG considerations relating to 
businesses, including climate change and greenhouse gas emissions, human capital and diversity, equity and inclusion. We make statements about our ESG 
goals and initiatives through information provided on our website, press statements and other communications, including through our Corporate 
Sustainability Report. Responding to these ESG considerations and implementation of these goals and initiatives involves risks and uncertainties, including 
those described under “Forward-Looking Statements,” requires investments and is impacted by factors that may be outside our control. In addition, some 
stakeholders may disagree with our goals and initiatives and the focus of stakeholders may change and evolve over time. Stakeholders also may have very 
different views on where ESG focus should be placed, including differing views of regulators in various jurisdictions in which we operate. Any failure, or 
perceived failure, by us to achieve our goals, further our initiatives, adhere to our public statements, comply with federal, state or international ESG laws 
and regulations or meet evolving and varied stakeholder expectations and standards could result in legal and regulatory proceedings against us that could 
materially adversely affect our business, reputation, results of operations, financial condition and stock price.

RISKS RELATED TO CYBERSECURITY AND PRIVACY.

We are subject to risks relating to our information technology systems.

We rely on information technology networks and systems to process, transmit and store electronic information, operate our business and 

communicate among our locations and with our customers, suppliers and other interested parties. Such information technology systems are subject to: (i) 
interruption or damage from power outages; (ii) cyber security breaches and other types of unauthorized access and/or use; and (iii) cyberattacks in the 
form of computer viruses, worms, malicious computer programs, denial‑of‑service attacks and other illegal or illicit means. Cyberattack and security 
breach strategies and methods continue to evolve and become more sophisticated. Accordingly, preventing intrusions and detecting successful intrusions 
and defending against them continues to be more difficult and requires ever-increasing vigilance.

A breach in cyber security could result in manipulation and destruction of sensitive data, cause critical systems to malfunction, be damaged or shut 

down and lead to disruption of our operations and production downtimes, potentially for lengthy periods of time. Theft of personal or other confidential 
data and sensitive proprietary information could also occur as a result of a breach in cyber security, exposing us to costs and liabilities associated with 
privacy and data security laws in the jurisdictions in which we operate. Additionally, a breach could expose us, our customers, our suppliers and our 
employees to risks of misuse of such information. Such negative consequences of cyberattacks or security breaches could adversely affect our reputation, 
competitive position, business or results of operations. The lost profits and increased costs related to cyber or other security threats or disruptions may not 
be fully insured against or indemnified by other means.

24

 
In addition, from time to time we may implement new technology systems or replace and/or upgrade our current information technology systems. 
These upgrades or replacements may not improve our productivity to the levels anticipated and may subject us to inherent costs and risks associated with 
implementing, replacing and updating these systems, including potential disruption of our internal control structure, substantial capital expenditures, 
demands on management time and other risks of delays or difficulties in transitioning to new systems or of integrating new systems into other existing 
systems. Our inability to prevent information technology system disruptions or to mitigate the impact of such disruptions could have an adverse effect on 
us.

RISKS RELATED TO TAX REGULATIONS.

We may not be able to utilize all of our net operating loss carryforwards.

Our ability to utilize our net operating loss carryforwards and other tax attributes could be limited to the extent they expire before we fully utilize 

them or if changes in federal or certain state tax laws reduce or eliminate our ability to use them to offset income taxes. Additionally, a change in our 
ownership, specifically a change in ownership of more than 50% during any period of 36 consecutive months (“ownership change”), as determined under 
the Internal Revenue Code of 1986 (“Code”), could reduce our ability to fully use our net operating loss carryforwards and other significant tax attributes.

Furthermore, our tax returns for certain past years are still subject to examination by taxing authorities, and the use of net operating loss 

carryforwards in future periods could trigger a review of attributes and other tax matters in years that are not otherwise subject to examination. After our 
net operating loss carryforwards and other significant tax attributes are fully utilized or if they become unavailable to us before we fully utilize them, our 
future income will not be shielded from federal and state income taxation and the funds otherwise available for general corporate purposes would be 
reduced.

We could engage in transactions involving our common shares that impair the use of our federal income tax attributes.

Section 382 of the Code affects our ability to use our federal income tax attributes, including our net operating loss carryforwards, following a more 
than 50% change in ownership during any period of 36 consecutive months, an ownership change, as determined under the Code. Certain transactions may 
be included in the calculation of an ownership change, including transactions involving our repurchase or issuance of our common shares. When we engage 
in any transaction involving our common shares that may be included in the calculation of an ownership change, our practice is to first perform the 
calculations necessary to confirm that our ability to use our federal income tax attributes will not be affected. These calculations are complex and reflect 
certain necessary assumptions. Accordingly, it is possible that we could engage in a transaction involving our common shares that causes an ownership 
change and inadvertently impairs the use of our federal income tax attributes. Furthermore, we may intentionally pursue a transaction that impairs the use 
of our federal income tax attributes if our strategy changes.

RISKS RELATED TO OUR COMMON STOCK.

Payment of dividends may not continue in the future and our payment of dividends and stock repurchases are subject to restrictions.

Our Board of Directors has declared a cash dividend for each quarter since the summer of 2007. In addition, our Board of Directors has authorized a 
stock repurchase program. The future declaration and payment of dividends and the purchase of our shares under the repurchase program, if any, are at the 
discretion of the Board of Directors and will depend on a number of factors, including our financial and operating results, including the availability of 
surplus and/or net profits, liquidity position, anticipated cash requirements and regulatory rules. Additionally, our Revolving Credit Facility and the 
indentures for our 4.625% Senior Notes and 4.50% Senior Notes impose limitations on our ability to pay dividends and repurchase our common shares. We 
can give no assurance that dividends will be declared and paid, that dividends will not be reduced or that purchases of our shares pursuant to our repurchase 
program will occur in the future.

Delaware law and our governing documents may impede or discourage a takeover, which could adversely affect the value of our common stock.

Provisions of Delaware law and our certificate of incorporation and bylaws may discourage a change of control of our company or deter tender 
offers for our common stock. We are currently subject to anti-takeover provisions under Delaware law. These anti‑takeover provisions impose various 
impediments to the ability of a third party to acquire control of us. Additionally, provisions of our certificate of incorporation and bylaws impose various 
procedural and other requirements, which could make it more difficult for stockholders to effect certain corporate actions. For example, our certificate of 
incorporation authorizes our Board of Directors to determine the rights, preferences and privileges and restrictions of unissued shares of preferred stock 
without any vote or action by our stockholders. As a result, our Board of Directors can authorize and issue shares of preferred stock with voting or 
conversion rights that 

25

 
could adversely affect the voting or other rights of holders of common stock. Our certificate of incorporation also divides our Board of Directors into three 
classes of directors who serve for staggered terms. A significant effect of a classified Board of Directors may be to deter hostile takeover attempts because 
an acquirer could experience delays in replacing a majority of directors. Moreover, stockholders are not permitted to call a special meeting.

RISKS RELATED TO PUBLICLY TRADED U.S. MANUFACTURING COMPANIES.

As a publicly traded U.S. manufacturing company, we are subject to a variety of other risks, each of which could adversely affect our financial 

position, results of operations or cash flows or the price of our common stock. These risks include but are not limited to:

•

•

•

•

•

•

•

•

•

•

•

•

•

the ability to attract and retain key management and other personnel and develop effective succession plans;

skills shortages in engineering, manufacturing, technology, construction and maintenance contractors and other labor market inadequacies;

regulations that subject us to additional capital or margin requirements or other restrictions that make it more difficult to hedge risks 
associated with our business or increase the cost of our hedging activities;

compliance with a wide variety of employment, minimum wage, health and safety laws and regulations and changes to such laws and 
regulations;

new or modified legislation related to health care;

pursuing growth through acquisitions, including the ability to identify acceptable acquisition candidates, finance and consummate 
acquisitions on favorable terms and successfully integrate acquired assets or businesses;

protection of intellectual property, including patents, trademarks, trade secrets and copyrights, from infringement by others and the potential 
defense of claims, whether meritorious or not, alleging the unauthorized use of the intellectual property of others;

the exertion of influence over us, individually or collectively, by a few entities with concentrated ownership of our stock;

failure to meet the expectations of investors, including recent environmental, sustainability and governance expectations and other factors 
that are beyond the control of an individual company; 

disputes, legal proceedings or investigations, whether meritorious or not, with respect to a variety of matters, including matters related to 
personal injury, employees, taxes, contracts and product liability;

taxation by multiple jurisdictions and the impact of such taxation on effective tax rate and the amount of taxes paid;

changes in tax laws and regulations; and

compliance with Section 404 of the Sarbanes-Oxley Act of 2002, including the potential impact of compliance failures.

Under our equity incentive plan, participants may elect to have us withhold common shares to satisfy minimum statutory tax withholding 
obligations arising from the recognition of income and the vesting of restricted stock, restricted stock units and performance shares. When we 
withhold these shares, we are required to remit to the appropriate taxing authorities the market price of the shares withheld by us on the date of 
withholding. The withholding of common shares by us could be deemed a purchase of such common shares.
In September 2018, our Board of Directors authorized us to repurchase an indeterminate number of shares of our common stock at an aggregate 
market value of up to $100.0 million. At December 31, 2022, $93.1 million remained available to repurchase our common shares pursuant to the 
stock repurchase program. The September 2018 authorization does not have an expiration date.

The following discussion and analysis of our financial condition and results of operations should be read in conjunction with our consolidated 
financial statements and related notes included in Item 8. “Financial Statements and Supplementary Data” of this Annual Report on Form 10-K (“Report”). 
For a detailed discussion of items impacting the year ended December 31, 2020, as well as a year‑to‑year comparison of our financial position and results 
of operations for the years ended December 31, 2021 and December 31, 2020, refer to Part II, Item 7. “Management’s Discussion and Analysis” of our 
Annual Report on Form 10-K for the years ended December 31, 2020 and 2021, respectively, filed with the Securities and Exchange Commission (“SEC”) 
on February 26, 2021 and March 1, 2022, respectively.

Non-GAAP Financial Measures

This information 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 generally accepted accounting principles (“GAAP”) in the statements of income, balance sheets or statements of cash flows of the 
company. We have provided a reconciliation of non-GAAP financial measures to the most directly comparable financial measure in the accompanying 
tables. We have also provided discussion of the reasons we believe that presentation of the non-GAAP financial measures provide useful information to 
investors, as well as any additional ways in which we use the non-GAAP financial measures. The non-GAAP financial measures used in the following 
discussions are Conversion Revenue (defined as Net Sales less the Hedged Cost of Alloyed Metal, see below in “Metal Pricing Policies” discussion), 
earnings before interest, taxes, depreciation and amortization adjusted for non-run-rate items (“Adjusted EBITDA”) and ratios related thereto. 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.

In the discussion of operating results below, we refer to certain items as “non-run-rate items.” For purposes of such discussion, non-run-rate items 
are items that, while they may recur from period-to-period: (i) are particularly material to results; (ii) affect costs primarily as a result of external market 
factors; and (iii) may not recur in future periods if the same level of underlying performance were to occur. Non-run-rate items are part of our business and 
operating environment but are worthy of being highlighted for the benefit of readers of our financial statements. Our intent is to allow users of the financial 
statements to consider our results both in light of and separately from such items. For a reconciliation of Adjusted EBITDA to Net loss, see below in 
“Results of Operations - Selected Operational and Financial Information.” 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 our control and/or cannot be reasonably 
predicted or provided without unreasonable effort.

Changes in Presentation of Non-GAAP Financial Measures

Change from Value Added Revenue to Conversion Revenue. Beginning with the year ended December 31, 2022, we determined that we will rename 

our previously used non-GAAP financial measure, “value added revenue” or “VAR,” to “Conversion Revenue.” The change is based on discussions with 
staff of the SEC pertaining to comment letters received during 2022 and is intended to more clearly characterize the metric as a subcomponent of revenue. 
Separately, due to high inflationary trends and the historically unprecedented volatility of alloy costs starting in early 2022, we renegotiated certain 
customer contracts and amendments to existing contracts to replace future price adjustments based on higher commodity and alloy costs with adjustments 
that pass through commodity and alloy cost. In addition, effective January 1, 2022, we have determined that we will prospectively change our approach 
from including a portion of alloyed metal cost within Hedged Cost of Alloyed Metal to include all alloyed metal cost. Periods prior to 2022 have not been 
adjusted as these changes were deemed effective as of January 1, 2022. This approach further aligns the presentation with our business model objective of 
“metal price neutrality,” as described below in our “Metal Pricing Policies” discussion. We have also expanded our disclosures regarding the nature of the 
costs included in the Hedged Cost of Alloyed Metal amounts in light of the comments from the SEC. See the table in “Results of Operations – Selected 
Operational and Financial Information” below for further details.

Change to Adjusted EBITDA. We have determined that we will revise our presentation of Adjusted EBITDA to no longer adjust our operating 

results for the impact of last-in, first-out (“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 is based on discussions with the SEC pertaining to comment letters received during 2022. For 
comparability, references to prior periods’ Adjusted EBITDA have been updated to show the effect of this change. See the table in “Results of Operations – 
Selected Operational and Financial Information” below for further details.

30

 
Metal Pricing Policies

Our pricing policies and hedging program are intended to significantly reduce or eliminate the impact on our profitability of fluctuations in the 

underlying price of primary and scrap, or recycled, aluminum, our main raw material, and certain alloys so that our earnings are predominantly associated 
with the conversion of aluminum to semi‑fabricated mill products. To allow users of our financial statements to consider the impact of aluminum and alloy 
cost on our Net sales, we disclose Net sales as well as Conversion Revenue, which is Net sales less the Hedged Cost of Alloyed Metal. As used in this 
discussion, “Hedged Cost of Alloyed Metal” is the cost of aluminum at the average Midwest Transaction Price (“Midwest Price”) plus the cost of alloying 
elements and any realized gains and/or losses on settled hedges related to the metal sold in the referenced period. The average Midwest Price of aluminum 
reflects the primary aluminum supply/demand dynamics in North America. For a reconciliation of Conversion Revenue to Net sales, see below in “Results 
of Operations - Selected Operational and Financial Information.”

Molten Metal and Magnesium Supply Chain Issues

As we have previously discussed, our rolling mill facility located in Warrick County, Indiana (“Warrick”) faced specific challenges with the 
September 2021 force majeure declaration of its primary magnesium supplier, US Magnesium, LLC (“US Mag”), which resulted in a significant reduction 
in deliveries while we were also being impacted by the operational challenges Alcoa Corporation was experiencing at its adjacent smelter, which supplies 
molten metal to Warrick. In June 2022, US Mag deliveries unexpectedly stopped while performance of the smelter also rapidly deteriorated, negatively 
impacting Warrick’s operating efficiency and financial performance. As a result of the abrupt and unexpected decline in magnesium supply, on July 7, 
2022, we declared force majeure at Warrick due to the limited availability of magnesium utilized in the production of our beverage and food packaging 
products, reducing our ability to produce those products at the time. 

After successfully securing and qualifying magnesium from additional sources, on September 6, 2022 we announced that we had lifted our force 

majeure declaration and have now sourced Warrick's magnesium requirements through 2023 and beyond. We believe our supply base is now well 
diversified, as it is not reliant on any one single supplier or geographical region. In addition, the molten metal supply at Warrick has improved to an 
acceptable level and we have secured access to alternative sources of molten metal to further diversify our Warrick metal supply and mitigate the risk of 
further smelter operational disruptions.   

Management Review of 2022 and Outlook for the Future

Review

The full year 2022 was a pivotal year in our evolution as we believe we laid the necessary groundwork to position ourselves 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. 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 Spokane, Washington (“Trentwood”) facility in the third quarter of 2022.

Outlook

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 a temporary low point. 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, diverse end markets with strong secular growth characteristics, deep customer relationships 
and multi-year contracts with strategic partners. 

We remain well positioned to navigate the current demand environment prevailing in our end markets in 2023. We expect demand in commercial 

aerospace to continue to strengthen throughout 2023 towards levels before the Coronavirus Disease 2019 (“COVID‑19”) pandemic with both business jet 
and defense remaining strong. In our beverage and food packaging (“Packaging”) end market, we expect our 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 (“GE Products”) end market demand is expected to soften for plate and rod and 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 end market 
(“Automotive Extrusions”), we do not expect a meaningful recovery until mid-to-late 2023.

31

 
We are cautiously optimistic our consolidated adjusted EBITDA margin (Adjusted EBITDA as a percentage of Conversion Revenue) will begin to 

strengthen in 2023 as we return to more normalized costs, improved efficiencies and continued commercial actions.

Results of Operations

Fiscal 2022 Summary

•

•

•

•

•

•

•

•

•

Strong demand for GE products and Packaging;

Increasing demand for our aerospace and high strength products (“Aero/HS products”) within commercial aerospace while defense and 
business jet applications demand remained strong;

Modest increase in Automotive Extrusions shipments as the market slowly continued to recover;

Molten metal and magnesium supply chain issues impacted results;

Diversification of our supply base to no longer be reliant on a single supplier or geographical region;

Negotiated more efficient contained metal and alloy cost pass throughs and commodity price adjustments in our customer contracts to help 
mitigate the impact of higher material and other inflationary costs on our business;

Completion of planned major outage, which included refurbishment of the large stretcher, at our Trentwood facility;

As of December 31, 2022, we had $615.2 million of combined cash and cash equivalents and net borrowing availability under our revolving 
credit facility with Wells Fargo Bank, National Association, as administrative agent, and the other financial institutions party thereto 
(“Revolving Credit Facility”);

We paid a total of approximately $50.1 million, or $3.08 per common share, in cash dividends to stockholders, including holders of restricted 
stock, and dividend equivalents to holders of certain restricted stock units during the year ended December 31, 2022, reflecting a 7% increase 
in the quarterly dividend compared with the prior year ended December 31, 2021.

Consolidated Selected Operational and Financial Information

The following data should be read in conjunction with our consolidated financial statements and the notes thereto included in Item 8. “Financial 

Statements and Supplementary Data” of this Report.

Net Sales. We reported Net sales for 2022 of $3,427.9 million, compared to $2,622.0 million for 2021. The increase in Net sales reflected a 132.6 

million pound (12%) increase in shipment volume and a $0.39/lb increase in average realized sales price per pound. The shipment volume increase 
reflected: (i) a 113.6 million pound (21%) increase in Packaging reflecting a full year of shipments during 2022 as a result of our Warrick acquisition, 
which was completed on March 31, 2021, partially impacted by reduced shipments in the second half of 2022 due to the third quarter force majeure event 
at Warrick; (ii) a 24.9 million pound (15%) increase in Aero/HS products reflecting continued strength in demand for our business jet and defense related 
applications, and improved demand for commercial aerospace as we continued to see the recovery in air travel and higher shipments of new aircraft from 
both major airframe producers, partially offset by constrained plate shipments during the quarter ended September 30, 2022 due to our planned major 
outage at our Trentwood facility; (iii) a 5.7 million pound (2%) increase in GE products reflecting continued strong underlying demand for semiconductor 
plate and industrial and machine tools; and (iv) a 2.5 million pound (3%) increase in Automotive Extrusions, which was relatively flat over prior year, 
driven by the shortage of semiconductors and industry supply chain issues that impacted the North American automotive production levels. The shipment 
volume increase was partially offset by a 14.1 million pound (54%) decrease in our other industrial end market application (“Other products”). The increase 
in average realized sales price per pound reflected a $0.28/lb (21%) increase in average Hedged Cost of Alloyed Metal prices per pound and an $0.11/lb 
(11%) increase in Conversion Revenue per pound reflecting higher pricing and surcharges to offset higher inflationary and commodity related costs. See 
the table in “Selected Operational and Financial Information” below for further details.

Cost of Products Sold, Excluding Depreciation and Amortization and Other Items (“Cost of products sold”). Cost of products sold for 2022 totaled 
$3,180.2 million, or 93% of Net sales, compared to $2,348.1 million, or 90% of Net sales, in 2021. The increase during 2022 compared to 2021 of $832.1 
million reflected: (i) a $534.4 million increase in Hedged Cost of Alloyed Metal and (ii) a $297.7 million increase in net manufacturing conversion and 
other costs. Of the $534.4 million increase in Hedged Cost of Alloyed Metal, $355.6 million was due to higher hedged metal cost and $178.8 million was 
due to higher shipment volume, as discussed above in “Net Sales.” The $297.7 million increase in net manufacturing conversion and other costs was 
primarily due to: (i) a $120.9 million increase related to higher sales, primarily due to a full year of shipments during 2022 as a result of our Warrick 
acquisition, which was 

32

 
completed on March 31, 2021; (ii) an $85.9 million increase in manufacturing costs due to lower efficiencies and higher employee related costs; (iii) $49.8 
million of higher benefits and overhead costs; (iv) $28.4 million of higher energy, freight and metal costs driven by inflation, transportation bottlenecks and 
supply chain inefficiencies; and (v) $8.3 million of higher planned major maintenance costs. See “Selected Operational and Financial Information” below 
for a further discussion of the comparative results of operations for 2022 and 2021.

Depreciation and Amortization. Depreciation and amortization for 2022 was $106.9 million compared to $91.5 million for 2021. The increase of 

$15.4 million was primarily attributable to a full year of Warrick operations.

Selling, General, Administrative, Research and Development (“SG&A and R&D”). SG&A and R&D expense totaled $110.9 million in 2022 

compared to $118.8 million in 2021. The decrease in 2022 compared with 2021 was primarily due to a $16.8 million decrease in legal, consulting and 
outsourced service expenses primarily related to the completion of Warrick integration activities, partially offset by: (i) a $6.7 million increase due to the 
addition of Warrick operations and (ii) a $2.4 million increase in salaries and benefits.

Goodwill Impairment. Goodwill impairment of $20.5 million for the year ended December 31, 2022 reflected our write-off of the goodwill we 

obtained from our acquisition of Warrick. See Note 4 of Notes to Consolidated Financial Statements included in this Report for further details.

Restructuring Costs (Benefit). Restructuring costs (benefit) reflects the impacts of our restructuring plans initiated in 2022 and 2020. See Note 12 of 

Notes to Consolidated Financial Statements included in this Report for further information regarding the restructuring plans.

Other Operating Charges (Income), Net. Other operating charges (income), net, of $3.2 million for the year ended December 31, 2022 was primarily 

due to the impairment of our favorable commodity contract intangible asset. See Note 4 of Notes to Consolidated Financial Statements included in this 
Report for further details.

Interest Expense. Interest expense represents cash and non-cash interest expense incurred on our unsecured senior notes and our Revolving Credit 

Facility, net of capitalized interest. See Note 9 of Notes to Consolidated Financial Statements included in this Report for further information regarding 
interest expense, capitalized interest expense and a discussion of our debt and credit facilities that were in effect during each of the years 2022 and 2021. 

Other Income (Expense), Net. See Note 9 and Note 13 of Notes to Consolidated Financial Statements included in this Report for details.

Income Tax Benefit. The income tax benefit for 2022 was $8.3 million, resulting in an effective tax rate of 21.9%. The difference between the 
effective tax rate and the projected blended statutory tax rate for 2022 was primarily due to: (i) an increase of 3% due to various permanent items not 
deductible for tax purposes; (ii) an increase of 2% related to non-deductible compensation expense; and (iii) an increase of 1% related to state taxes, 
partially offset by a decrease of 6% related to a Federal Research and Development Credit.

The income tax benefit for 2021 was $5.5 million, resulting in an effective tax rate of 22.9%. There was no material difference between the effective 

tax rate and the projected blended statutory tax rate for 2021.

Mark-to-market loss on derivative instruments for 2022 and 2021 represents loss on non-designated commodity hedges. Additionally, in 2021, the 
loss represents the reversal of mark-to-market loss on hedges entered into prior to the adoption of Accounting Standards Update No. 2017-12, 
Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities and settled in the periods presented above. 
Adjusted EBITDA reflects the realized loss of such settlements.
See Note 4 of Notes to Consolidated Financial Statements included in this Report for additional information relating to the impairment of goodwill 
in 2022.
Non-run-rate environmental expenses are related to legacy activities at operating facilities prior to July 6, 2006. See Note 10 of Notes to 
Consolidated Financial Statements included in this Report for additional information relating to the environmental expenses.
Acquisition costs are non-run-rate acquisition-related transaction costs, which include professional fees, as well as non‑cash hedging charges 
recorded in connection with our Warrick acquisition.

Adjusted EBITDA for 2022 was $42.9 million lower than Adjusted EBITDA for 2021. Adjusted EBITDA for 2022 reflected a full year of 

Packaging volume during 2022 as a result of our Warrick acquisition on March 31, 2021, offset by approximately $73.0 million of incremental costs 
associated with magnesium and metal supply chain issues at our packaging operations, see above in “Molten Metal and Magnesium Supply Chain Issues,” 
coupled with the planned outage at our Trentwood facility. In addition, we had inflation-driven higher energy, manufacturing and employee related cost that 
were not fully recovered through pricing increases. See above in “Consolidated Selected Operational and Financial Information” for further details.

Hedged Cost of Alloyed Metal for 2022 and 2021 was comprised of $2,028.2 million and $1,552.4 million, respectively, reflecting the cost of 
aluminum at the average Midwest Price and the cost of certain alloys used in the production process, as well as metal price exposure on shipments 
that we hedged with realized losses upon settlement of $17.0 million in 2022 and realized gains upon settlement of $41.6 million in 2021, all of 
which were included within both Net sales and Cost of products sold in our Statements of Consolidated (Loss) Income. See Note 8 of Notes to 
Consolidated Financial Statements included in this Report for the total realized loss (gain) on aluminum hedges for which we hedged the metal price 
exposure externally.
As previously described, effective January 1, 2022, we prospectively changed our approach of quantifying Hedged Cost of Alloyed Metal from 
including a portion of alloyed metal cost to include all alloyed metal cost. This prospective change resulted in the following decreases of Conversion 
Revenue by end market: (i) $32.2 million of Aero/HS products; (ii) $49.4 million of Packaging; (iii) $22.4 million of GE products; (iv) $7.1 million 
of Automotive extrusions; and (v) $0.8 million of Other products, for a total decrease of $111.9 million in 2022 compared to our historical 
presentation of this metric.

In April 2022, we executed Amendment No. 3 to our Revolving Credit Facility to, among other things: (i) increase the commitment to $575.0 
million; (ii) extend the maturity date; (iii) update our borrowing base; and (iv) update relevant benchmark provisions from London Interbank 
Offered Rate (“LIBOR”) to Term Secured Overnight Financing Rate (“Term SOFR”). See Note 9 of Notes to Consolidated Financial Statements 
included in this Report for further details. Borrowing availability under the Revolving Credit Facility was determined by a borrowing base 
calculated as of December 31, 2022 and December 31, 2021 using the terms of the Revolving Credit Facility in effect as of those dates.

We place our cash in bank deposits and money market funds with high credit quality financial institutions. Cash equivalents primarily consist of 

money market funds, which are highly liquid. 

See Note 16 of Notes to Consolidated Financial Statements included in this Report for information regarding restricted cash at December 31, 2022.

There were no borrowings under our Revolving Credit Facility during the years ending December 31, 2022 or December 31, 2021. See “Sources of 

Liquidity” below for a further discussion of subsequent borrowing activity.

Cash used in operating activities for the year ended December 31, 2022 reflected results of business activity described within “Consolidated 
Selected Operational and Financial Information” above, as well as the following working capital changes: (i) an increase in inventory of $120.8 million, 
primarily driven by higher inventory pounds built at our Warrick facility to mitigate the impact of supply chain disruptions related to magnesium and hot 
metal supply and at our Trentwood facility to prepare for the planned outages associated with our large stretcher refurbishment, as well as higher per pound 
inventory cost due to higher metal prices in ending inventory; (ii) a decrease in accounts payable of $61.2 million, primarily due to timing of purchases and 
a decrease in period ending metal prices; and (iii) a decrease in accounts receivable of $15.0 million due to the timing and mix of sales, as well as a 
decrease in period ending metal prices.

Cash provided by operating activities for the year ended December 31, 2021 reflected results of business activity for the year ended December 31, 
2021, as well as the following working capital changes: (i) an increase in accounts payable of $112.5 million, primarily driven by Warrick payables added 
during the year ended December 31, 2021 and higher metal cost; (ii) an increase in trade and other receivables of $90.3 million, primarily driven by 
Warrick receivables added during the year ended December 31, 2021 and the remainder due to the timing and mix of sales and an increase in metal prices; 
and (iii) an increase in inventory of $43.5 million due primarily to higher inventory pounds to satisfy increased demand, as well as a higher per pound 
inventory cost.

See Statements of Consolidated Cash Flows included in this Report for further details on our cash flows from operating, investing and financing 

activities for the years ended December 31, 2022 and December 31, 2021.

Sources of Liquidity

We believe our available cash and cash equivalents, borrowing availability under the Revolving Credit Facility and funds generated from operations 

are our most significant sources of liquidity, and that our Revolving Credit Facility and unsecured notes have covenants that allow us to operate our 
business with limited restrictions and significant flexibility for the foreseeable future. While we believe these sources will be sufficient to finance our 
working capital requirements, planned capital expenditures, investments, debt service obligations and other cash requirements for at least the next 12 
months, and while we also believe that alternative sources of liquidity will remain available in the event we seek to add liquidity for opportunistic or other 
reasons in the future, our ability to fund such cash requirements will depend upon our future operating performance (which will be affected by prevailing 
economic conditions) and financial, business and other factors, some of which are beyond our control.

We do not believe that covenants contained in the Revolving Credit Facility are reasonably likely to limit our ability to raise additional debt or 

equity should we choose to do so during the next 12 months, nor do we believe it is likely that during the next 12 months we will trigger the availability 
threshold that would require measuring and maintaining a fixed charge coverage ratio.

At February 20, 2023, we had $10.2 million in outstanding borrowings under the Revolving Credit Facility after repaying $19.3 million on total 

borrowings of $29.5 million incurred subsequent to December 31, 2022. See Note 9 of Notes to Consolidated Financial Statements included in this Report 
for a description of our Revolving Credit Facility.

We engage in certain customer-based supply chain financing programs to accelerate the receipt of payment for outstanding accounts receivable from 

certain customers. Costs of these programs are typically reimbursed to us by the customer. Receivables transferred under these customer-based supply 
chain financing programs generally meet the requirements to be accounted for as sales resulting in the derecognition of such receivables from our 
consolidated balance sheets. Receivables involved with these customer‑based supply chain finance programs for the year ended December 31, 2022 
constituted approximately 47% of our Net sales. See Note 1 of Notes to Consolidated Financial Statements included in this Report for further details with 
respect to these supply chain financing programs.

Debt

See Note 9 of Notes to Consolidated Financial Statements included in this Report for further details with respect to the 4.50% Senior Notes due 

2031 (“4.50% Senior Notes”) and 4.625% Senior Notes due 2028 (“4.625% Senior Notes”) and the redemption of our 6.50% Senior Notes due 2025 
(“6.50% Senior Notes”).

We do not believe that covenants in the indenture governing the 4.50% Senior Notes and 4.625% Senior Notes are reasonably likely to limit our 

ability to obtain additional debt or equity financing should we choose to do so during the next 12 months.

Capital Expenditures and Investments

We strive to strengthen our competitive position across our end markets through strategic capital investment. Significant investments over the past 

decade have positioned us well with increased capacity and expanded manufacturing capabilities while more recent capital projects have focused on further 
enhancing manufacturing cost efficiency, improving product quality and promoting operational security, which we believe are critical to maintaining and 
strengthening our position in an increasingly competitive market environment. A significant portion of our capital spending over the past several years 
related to the modernization project at our Trentwood rolling mill, which focused on equipment upgrades throughout the process flow to reduce conversion 
costs, increase efficiency and further improve our competitive cost position on all products produced at our Trentwood facility. In addition, a significant 
portion of the investment also focused on modernizing legacy equipment and the process flow for thin gauge plate to achieve KaiserSelect® quality 
enhancements for these Aero/HS products and GE products. These improvements have allowed us to gain incremental manufacturing capacity to enable 
future sales growth. In 2022, we continued spending on our previously announced capital project to add a fourth roll coat line at our Warrick facility to 
increase our capacity for higher margin coated packaging product. Total capital expenditures were $142.5 million in 2022, of which $74.7 million related to 
the new roll coat line and $67.8 million primarily related to critical sustaining capital projects, and $58.0 million in 2021, primarily related to critical 
sustaining capital projects. 

Our capital investment plans remain focused on supporting demand growth through capacity expansion, sustaining our operations, enhancing 

product quality and increasing operating efficiencies. We anticipate total capital spending in 2023 of approximately $170.0 million to $190.0 million, of 
which approximately 60% of total spending will be focused on growth initiatives, primarily reflecting continued investment in the new roll coat line at 
Warrick. We will continue to deploy capital thoughtfully to ensure that investment decisions align with demand expectations in order to maximize the 
earnings potential of the business and maintain financial strength and flexibility.

37

 
Capital investments will be funded using cash generated from operations, available cash and cash equivalents, borrowings under the Revolving 

Credit Facility and/or other third-party financing arrangements. The level of anticipated capital expenditures may be adjusted from time to time depending 
on our business plans, our price outlook for fabricated aluminum products, our ability to maintain adequate liquidity and other factors. No assurance can be 
provided as to the timing of any such expenditures or the operational benefits expected therefrom.

Dividends

We have consistently paid a quarterly cash dividend since the second quarter of 2007 to holders of our common stock, including holders of restricted 
stock, and have increased the dividend in each year since 2011. Nevertheless, as in the past, the future declaration and payment of dividends, if any, will be 
at the discretion of our Board of Directors and will depend on a number of factors, including our financial, including the availability of surplus and/or net 
profits, and operating results, financial position and anticipated cash requirements and contractual restrictions under our Revolving Credit Facility, the 
indentures for our 4.50% Senior Notes and 4.625% Senior Notes or other indebtedness we may incur in the future. We can give no assurance that dividends 
will be declared and paid in the future.

We also pay quarterly dividend equivalents to the holders of certain restricted stock units. Holders of performance shares are not paid a quarterly 

dividend equivalent, but instead are entitled to receive, in connection with the issuance of underlying shares of common stock for performance shares that 
ultimately vest, a one-time payment equal to the dividends such holder would have received if the number of such shares of common stock so issued had 
been held of record by such holder from the date of grant of such performance shares through the date of such issuance.

See our Statements of Consolidated Stockholders’ Equity and Note 18 of Notes to Consolidated Financial Statements included in this Report for 

information regarding dividends declared during 2022 and 2021 and subsequent to December 31, 2022.

Repurchases of Common Stock

We suspended share repurchases as of March 2020. We will continue to assess share repurchases as a part of our capital allocation priorities and 

strategic investment opportunities identified to support further growth in our business. At December 31, 2022, $93.1 million remained authorized and 
available for future repurchases of common stock under our stock repurchase program. See our Statements of Consolidated Stockholders’ Equity included 
in this Report for information regarding minimum statutory tax withholding obligations arising during 2022 and 2021 in connection with the vesting of 
non-vested shares, restricted stock units and performance shares.

Environmental Commitments and Contingencies

See Note 10 of Notes to Consolidated Financial Statements included in this Report for information regarding our environmental commitments and 

contingencies.

Contractual Obligations, Commercial Commitments and Off-Balance Sheet Arrangements

The discussion below summarizes our significant contractual obligations, commercial commitments and off-balance sheet arrangements as of 

December 31, 2022.

Principal and Interest on 4.50% Senior Notes and 4.625% Senior Notes. See Note 9 of Notes to Consolidated Financial Statements included in this 

Report for information, including the timing of principal and interest payments, associated with our debt.

Standby Letters of Credit. Standby Letters of Credit represents letters of credit issued under our Revolving Credit Facility. The letters of credit 

provide financial assurance of our payment of obligations, primarily related to workers’ compensation. The specific timing of payments with respect to 
such matters is uncertain. The letters of credit generally automatically renew every 12 months and terminate when the underlying obligations no longer 
require assurance or upon the maturity of our Revolving Credit Facility in April 2027. See Note 9 of Notes to Consolidated Financial Statements included 
in this Report for further information.

Uncertain Tax Liabilities. At December 31, 2022, we had uncertain tax positions which ultimately could result in tax payments. See Note 14 of 

Notes to Consolidated Financial Statements included in this Report for further information.

Deferred Compensation Plan Liability. As of December 31, 2022, we had deferred compensation plan liabilities for certain key employees, which 

were contingent upon investment performance, vesting and other eligibility requirements, including retirement 

38

 
dates. See Note 5 of Notes to Consolidated Financial Statements included in this Report for further information, including the total expense related to all 
benefit plans.

Operating Leases. Operating lease liabilities represent multi-year obligations for certain manufacturing facilities, warehouses, office space and 

equipment as of December 31, 2022. See Note 3 of Notes to Consolidated Financial Statements included in this Report for the maturity of our lease 
liabilities associated with our operating lease portfolio.

Finance Leases. Finance lease liabilities represent non-cancelable capital commitments as of December 31, 2022. We expect finance leases to be 

funded through available cash generated from our operations, cash and cash equivalents, borrowings under our Revolving Credit Facility and/or other third-
party financing arrangements. See Note 3 of Notes to Consolidated Financial Statements included in this Report for the maturity of our lease liabilities 
associated with our finance lease portfolio.

Pension and OPEB. See Note 5 of Notes to Consolidated Financial Statements included in this Report for additional information regarding the 

future net benefits we expect to pay with respect to our pension plans and our healthcare and life insurance postretirement benefit plan (“OPEB”).

Salaried VEBA Variable Contributions. See Note 5 of Notes to Consolidated Financial Statements included in this Report for additional information 

regarding our variable cash contributions to the voluntary employees’ beneficiary association (“VEBA”) that provides benefits for certain eligible retirees 
and their surviving spouses and eligible dependents (“Salaried VEBA”).

VEBA administrative fees. We are required to pay $0.3 million in annual administrative fees related to the VEBA that provides benefits for eligible 

retirees represented by certain unions and their surviving spouses and eligible dependents through September 2025. See Note 5 of Notes to Consolidated 
Financial Statements included in this Report for additional information.

Purchase Obligations. Cash outlays for purchase obligations consist primarily of commitments to purchase primary aluminum, recycled scrap 
aluminum, other alloys, energy and equipment. We have various contracts with suppliers of metals that require us to purchase minimum quantities of these 
metals in future years based primarily at the associated metal price at the time of payment. We believe the minimum required purchase quantities are lower 
than our current requirements for these metals. Physical delivery commitments with energy companies are in place to cover our exposure to fluctuations in 
electricity and natural gas prices and are based on fixed contractual rates and quantities. Equipment purchase obligations are based on scheduled payments 
to equipment manufacturers. 

Commitment Fees on Revolving Credit Facility. Future commitment fees on our Revolving Credit Facility are estimated based on the amount of 

unused credit under the facility at December 31, 2022 and assuming no extension of terms beyond the current maturity date of our Revolving Credit 
Facility, which is in April 2027. No borrowings were outstanding under our Revolving Credit Facility either throughout the year or as of December 31, 
2022. See Note 9 of Notes to Consolidated Financial Statements included in this Report for additional information. See “Sources of Liquidity” above for a 
discussion of subsequent borrowing activity.

Critical Accounting Estimates and Policies

Our consolidated financial statements are prepared in accordance with GAAP. In connection with the preparation of our financial statements, we are 

required to make assumptions and estimates about future events and apply judgments that affect the reported amounts of assets, liabilities, revenue and 
expenses and the related disclosures. We base our assumptions, estimates and judgments on historical experience, current trends and other factors that 
management believes to be relevant at the time our consolidated financial statements are prepared. On a regular basis, management reviews the accounting 
policies, assumptions, estimates and judgments to ensure that our financial statements are presented fairly and in accordance with GAAP. However, 
because future events and their effects cannot be determined with certainty, actual results could differ from our assumptions and estimates and such 
differences could be material.

In addition to the accounting estimates we discuss in Note 1 of Notes to Consolidated Financial Statements included in this Report, management 

believes that the following accounting estimates are critical to aid in fully understanding and evaluating our reported financial results and require 
management’s most difficult, subjective or complex judgments, resulting from the need to make 

39

 
estimates about the effects of matters that are inherently uncertain. Management has reviewed these critical accounting estimates and related disclosures 
with the Audit Committee of our Board of Directors.

Revenue Recognition.

  Judgments and Uncertainties

Potential Effect If Actual Results
Differ From Assumptions

  Although we believe that the judgments and 

estimates around recognizing revenue over time 
discussed herein are reasonable, actual results could 
differ and we may be exposed to losses or gains that 
could be material. A change in our estimated 
average margins by 5% would have had an impact 
of approximately $0.2 million to Net (loss) income 
for the year ended December 31, 2022.

We decide at the outset of entering into contracts 
with customers whether our performance 
obligations as specified in these contracts are 
satisfied over time or at a point in time. To 
recognize revenue over time means that we will 
need to synchronize revenue recognition with 
progress toward completion of the performance 
obligation.

If we have determined that revenue will be 
recognized over time for a specific customer order, 
the earliest point in our production process that we 
will recognize revenue will be the point that the 
product cannot be directed to another customer. In 
most cases, this happens at the time we begin to 
mold the ingot or billet, either by flat rolling the 
ingot or by extruding the billet through a die. For 
custom alloys, we would begin recognizing revenue 
over time at the point the custom alloy billet is cast.

Approximately 81% of our business is recognized at 
a point in time with the remaining 19% recognized 
over time.

  We follow the input method of recognizing 
revenue over time. Under this approach, 
revenue is recognized on products in 
production based on the cost incurred to date 
plus a reasonable margin. Cost incurred to 
date is based on resources consumed, labor 
hours expended and other costs incurred 
relative to the total inputs expected in order to 
satisfy a performance obligation. Reasonable 
margins are estimated using an average 
margin of the respective production facility 
producing the product.

For purposes of recognizing revenue over 
time on products that are in work‑in-process 
(“WIP”) as of the period end, we make the 
assumption that the average margins at the 
respective production facilities are reasonably 
close to the individual product margins that 
are in WIP.

Income Tax.

We have tax attributes available to offset the impact 
of future income taxes. We have a process for 
determining the need for a valuation allowance with 
respect to these attributes. The process includes an 
extensive review of both positive and negative 
evidence including our earnings history, future 
earnings, adverse recent occurrences, carryforward 
periods, an assessment of the industry and the 
impact of the timing differences.

We expect to record a full statutory tax provision in 
future periods and, therefore, the benefit of any tax 
attributes realized will only affect future balance 
sheets and statements of cash flows.

Financial statements for interim periods include an 
income tax provision based on the effective tax rate 
expected to be incurred in the current year.

  Judgments and Uncertainties

Potential Effect If Actual Results
Differ From Assumptions

  Although we believe that the judgments and 

estimates discussed herein are reasonable, actual 
results could differ and we may be exposed to losses 
or gains that could be material. A change in our 
effective tax rate by 1% would have had an impact 
of approximately $0.4 million to Net (loss) income 
for the year ended December 31, 2022.

  Inherent within the completion of our 
assessment of the need for a valuation 
allowance, we make significant judgments 
and estimates with respect to future operating 
results, timing of the reversal of deferred tax 
assets and current market and industry factors. 
In order to determine the effective tax rate to 
apply to interim periods, estimates and 
judgments are made (by taxable jurisdiction) 
as to the amount of taxable income that may 
be generated, the availability of deductions 
and credits expected and the availability of 
net operating loss carryforwards or other tax 
attributes to offset taxable income.

Making such estimates and judgments is 
subject to inherent uncertainties given the 
difficulty of predicting future tax rates, 
market conditions, customer requirements, the 
cost for key inputs such as energy and 
primary aluminum, overall operating 
efficiency and other factors. However, if, 
among other things: (i) actual results vary 
from our forecasts due to one or more of the 
factors cited above or elsewhere in this 
Report; (ii) income is distributed differently 
than expected among tax jurisdictions; (iii) 
one or more material events or transactions 
occur which were not contemplated; or (iv) 
certain expected deductions, credits or 
carryforwards are not available, it is possible 
that the effective tax rate for a year could vary 
materially from the assessments used to 
prepare the interim consolidated financial 
statements. See Note 14 of Notes to 
Consolidated Financial Statements included in
this Report for additional discussion of these 
matters.

Acquisitions, Goodwill and Intangible Assets.

We account for acquisitions using the acquisition 
method of accounting, which requires the assets 
acquired and liabilities assumed to be recorded at 
the date of acquisition at their respective estimated 
fair values.

We recognize goodwill as of the acquisition date as 
the excess over the fair values of the identifiable net 
assets acquired. Goodwill is tested for impairment 
on an annual basis as well as on an interim basis as 
events and changes in circumstances occur.

Definite-lived intangible assets acquired are 
amortized over the estimated useful lives of the 
respective assets, to reflect the pattern in which the 
economic benefits of the intangible assets are 
consumed. In the event the pattern cannot be 
reliably determined, we use a straight-line 
amortization method. Whenever events or changes 
in circumstances indicate that the carrying amount 
of the intangible assets may not be recoverable, the 
intangible assets will be reviewed for impairment.

  The judgments made in determining the 

  We do not believe there is a reasonable likelihood 

that there will be a material change in the estimates 
or assumptions we use to estimate the fair value of 
goodwill and intangible assets. Additionally, as of 
December 31, 2022, we do not believe any of our 
reporting units are at risk of failing the goodwill 
impairment test. However, if actual results are not 
consistent with our estimates and assumptions used 
in estimating future cash flows and fair values 
assigned to each class of assets acquired and 
liabilities assumed, we may be exposed to losses 
from impairment charges that could be material. For 
further details on goodwill and intangible assets, see 
Note 4 of Notes to Consolidated Financial 
Statements included in this Report.

estimated fair value assigned to each class of 
assets acquired and liabilities assumed, as 
well as asset lives, can significantly impact 
our results of operations. Fair values and 
useful lives of intangible assets are 
determined using the income approach 
valuation methodology, which is based on, 
among other factors, the expected future 
period of benefit of the asset, the various 
characteristics of the asset, long‑term 
forecasts of the business, projected cash flows 
and the rate used in discounting those cash 
flows. As the determination of an asset’s fair 
value and useful life involves management 
making certain estimates and because these 
estimates form the basis for the determination 
of whether or not an impairment charge 
should be recorded, these estimates are 
considered to be critical accounting estimates.

Pension and Other Postretirement Benefits.

Liabilities and expenses for pension and other 
postretirement benefits are determined using 
actuarial methodologies and incorporate significant 
assumptions, including the interest rate used to 
discount the future estimated liability, the expected 
long-term rate of return (“LTRR”) on plan assets 
and several assumptions relating to the employee 
workforce (salary increases, health care cost trend 
rates, retirement age and mortality). The most 
significant assumptions used in determining the 
estimated year-end obligations include the assumed 
discount rate and the LTRR.

In addition to the above assumptions used in the 
actuarial valuations, changes in plan provisions 
could also have a material impact on the net funded 
status of our pensions and other postretirement 
benefits. Additionally, our obligation to the Salaried 
VEBA is to pay an annual variable contribution 
amount based on the level of our cash flow. The 
funding status of the Salaried VEBA has no impact 
on our annual variable contribution amount. We 
have no control over any aspect of the plan. We rely 
on information provided to us by the Salaried 
VEBA administrator with respect to specific plan 
provisions such as annual benefits expected to be 
paid. See Note 5 of Notes to Consolidated Financial 
Statements included in this Report for additional 
information on our benefit plans.

  Since the recorded obligation represents the 
present value of expected postretirement 
benefit payments over the life of the plans, 
decreases in the discount rate (used to 
compute the present value of the payments) 
would cause the estimated obligation to 
increase. Conversely, an increase in the 
discount rate would cause the estimated 
present value of the obligation to decline.

  The impact on the combined pension and other 

postretirement liabilities of a change in the 
weighted average discount rate of ¼ of 1% would 
be approximately $3.5 million as of December 31, 
2022, and would impact pretax earnings in 2023 by 
approximately $0.3 million. A change in the 
assumption for the weighted average expected long-
term rate of return on plan assets of ¼ of 1% would 
impact pretax earnings by approximately $0.4 
million for 2023.

The LTRR on plan assets reflects an 
assumption regarding what the amount of 
earnings would be on existing plan assets 
(before considering any future contributions 
to the plan). Increases in the assumed LTRR 
would cause the projected value of plan assets 
available to satisfy postretirement obligations 
to increase, yielding a reduced net expense of 
these obligations. A reduction in the LTRR 
would reduce the amount of projected net 
assets available to satisfy postretirement 
obligations and, thus, cause the net expense of 
these obligations to increase.

A change in plan provisions could cause the 
estimated obligations to change. An increase 
in annual benefits expected to be paid would 
increase the estimated present value of the 
obligations and conversely, a decrease in 
annual benefits expected to be paid would 
decrease the estimated present value of the 
obligations.

Item 7A. Quantitative and Qualitative Disclosures About Market Risk 

The following quantitative and qualitative disclosures about market risk should be read in conjunction with Note 8 and Note 11 of Notes to 

Consolidated Financial Statements included in this Report. Our operating results are sensitive to changes in the prices of primary aluminum, certain 
alloying metals, natural gas, electricity and foreign currency, and also depend to a significant degree upon the volume and mix of products sold to 
customers. We have historically utilized hedging transactions to lock in a specified price or range of prices for certain products which we sell or consume in 
our production process, and to mitigate our exposure to changes in energy prices.

Aluminum

In 2022 and 2021, settlements of derivative contracts covering 271.9 million pounds and 187.2 million pounds, respectively, hedged shipments sold 

on pricing terms that created aluminum price risk for us. At December 31, 2022, we had derivative contracts with respect to approximately 60.5 million 
pounds and 2.5 million pounds to hedge sales to be made in 2023 and 2024, respectively, on pricing terms that create aluminum price risk for us.

Based on the aluminum derivative positions held by us to hedge firm-price customer sales agreements, we estimate that a $0.10/lb decrease in the 

London Metal Exchange (“LME”) market price of aluminum as of December 31, 2022 and December 31, 2021, with all other variables held constant, 
would have resulted in an unrealized mark-to-market loss of $6.3 million and $8.0 million, respectively, with corresponding changes to the net fair value of 
our aluminum derivative positions. Additionally, we estimate that a $0.05/lb decrease in the Midwest premium for aluminum as of December 31, 2022 and 
December 31, 2021, with all other variables held constant, would have resulted in an unrealized mark-to-market loss of $3.2 million and $4.0 million, 
respectively, with corresponding changes to the net fair value of our aluminum derivative positions.

Alloying Metals

We are exposed to the risk of fluctuating prices of certain alloying metals, especially copper, zinc and magnesium, to the extent that changes in their 
prices do not highly correlate with price changes for aluminum. Copper, zinc, magnesium and certain other metals are used in our remelt operations to cast 
rolling ingot and extrusion billet with the proper chemistry for our products. From time to time, we enter into forward contract swaps and/or physical 
delivery commitments with third parties to mitigate our risk from fluctuations in the prices of these alloys. As of December 31, 2022, we had forward swap 
contracts with settlement dates designed to align with the timing of scheduled purchases of zinc and copper (“Alloying Metals”) by our manufacturing 
facilities. We estimate that a $0.10/lb decrease in the market price of Alloying Metals as of December 31, 2022 and December 31, 2021, with all other 
variables held constant, would have resulted in an unrealized mark-to-market loss of $0.1 million and $0.6 million, respectively, with corresponding 
changes to the net fair value of our Alloying Metals derivative positions. 

Energy

We are exposed to risk of fluctuating prices for natural gas and electricity. We, from time to time, in the ordinary course of business, enter into 
hedging transactions and/or physical delivery commitments with firm prices with third parties to mitigate our risk from fluctuations in natural gas and 
electricity prices. We estimate that a $1.00 per mmbtu decrease in natural gas prices would have resulted in an unrealized mark-to-market loss of $3.5 
million and $5.2 million as of December 31, 2022 and December 31, 2021, respectively, with corresponding changes to the net fair value of our natural gas 
derivative positions. We estimate that a $5.00 per Mwh decrease in electricity prices as of December 31, 2021, would have resulted in an unrealized 
mark‑to‑market loss of $1.1 million with corresponding changes to the net fair value of our electricity derivative positions. As of December 31, 2022, we 
had no outstanding electricity derivative positions.

Foreign Currency

As of December 31, 2022, we hedged certain lease transactions and equipment purchases denominated in euros and British pounds using forward 

swap contracts with settlement dates through February 2024. We estimate that a 10% decrease in the exchange rate of our hedged foreign currencies to U.S. 
dollars would have resulted in $0.1 million and an immaterial unrealized mark-to-market loss as of December 31, 2022 and December 31, 2021, 
respectively, with corresponding changes to the net fair value of our foreign currency derivative positions. 

Our primary foreign exchange exposure is the operating costs of our London, Ontario facility. We estimate that a 10% change in the Canadian dollar 

exchange rate as of December 31, 2022 and December 31, 2021 would have resulted in an annual operating cost impact of $2.6 million and $2.2 million, 
respectively.

Opinions on the Financial Statements and Internal Control over Financial Reporting

We have audited the accompanying consolidated balance sheets of Kaiser Aluminum Corporation and subsidiaries (the “Company”) as of December 31, 
2022 and 2021, the related consolidated statements of (loss) income, comprehensive (loss) income, stockholders’ equity, and cash flows for each of the 
three years in the period ended December 31, 2022, and the related notes (collectively referred to as the “financial statements”). We also have audited the 
Company’s internal control over financial reporting as of December 31, 2022, based on criteria established in Internal Control — Integrated Framework 
(2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).

In our opinion, the financial statements referred to above present fairly, in all material respects, the financial position of the Company as of December 31, 
2022 and 2021, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2022, in conformity with 
accounting principles generally accepted in the United States of America. Also, in our opinion, the Company maintained, in all material respects, effective 
internal control over financial reporting as of December 31, 2022, based on criteria established in Internal Control — Integrated Framework (2013) issued 
by COSO.

Basis for Opinion

The Company’s management is responsible for these financial statements, for maintaining effective internal control over financial reporting, and for its 
assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Annual Report on Internal Control 
Over Financial Reporting. Our responsibility is to express an opinion on these financial statements and an opinion on the Company’s internal control over 
financial reporting based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) 
(PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and 
regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable 
assurance about whether the financial statements are free of material misstatement, whether due to error or fraud, and whether effective internal control 
over financial reporting was maintained in all material respects.

Our audits of the financial statements included performing procedures to assess the risks of material misstatement of the financial statements, whether due 
to error or fraud, and performing procedures to respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts 
and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by 
management, as well as evaluating the overall presentation of the financial statements. Our audit of internal control over financial reporting included 
obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the 
design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we 
considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.

Definition and Limitations of Internal Control over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting 
and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control 
over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly 
reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit 
preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are 
being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding 

47

 
 
REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM (CONTINUED)

prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial 
statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of 
effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of 
compliance with the policies or procedures may deteriorate.

Critical Audit Matters 

The critical audit matters communicated below are matters arising from the current-period audit of the financial statements that were communicated or 
required to be communicated to the audit committee and that (1) relate to accounts or disclosures that are material to the financial statements and (2) 
involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion 
on the financial statements, taken as a whole, and we are not, by communicating the critical audit matters below, providing separate opinions on the critical 
audit matters or on the accounts or disclosures to which they relate.

Revenue Recognition—Refer to Notes 1 and 17 to the financial statements

Critical Audit Matter Description

The Company recognizes revenue as it fulfills their performance obligations and transfers control of products to its customers. For products that have no 
alternative use and for which the Company has an enforceable right to payment (including a reasonable profit) throughout the production process, revenue 
is recognized over time. In general, revenue recognized over time primarily relates to the Company’s Aero/HS products and Automotive Extrusions, with 
the revenue for the remainder of its products recognized at a point in time. For contracts recognized over time, control transfer occurs incrementally during 
the Company’s production process as progress is made on fulfilling the performance obligation. The Company uses the input method of determining the 
progress, capturing direct costs beginning at the point that billet or cast ingot is introduced into production at either the extrusion phase or the rolling phase, 
respectively. For products in production, the Company recognizes revenue using the cost incurred to date plus an estimate of reasonable margin. As of 
December 31, 2022, net sales were $3,427.9 million, of which $645.0 million was recognized over time.

Given the volume of contracts that are recognized over time and the complexity of the determination of over time revenue, we identified revenue for over 
time contracts as a critical audit matter.

How the Critical Audit Matter Was Addressed in the Audit

Our audit procedures related to revenue recognized over time, included the following, among others:

• We tested management’s controls over revenue recognized over time, including those over cost incurred to date and estimates of reasonable margin.

• We tested the mathematical accuracy of management’s calculation of revenue recognized over time.

• We selected a sample of contracts with customers and performed the following:

o We evaluated whether the contracts were properly included in management’s calculation of revenue recognized over time based on the terms and 

conditions of each contract.

o We tested that control transfer occurred as progress was made toward fulfilling the performance obligation.

• We evaluated the estimates of reasonable margin by developing a range of independent estimates and comparing our estimates to those used by 

management.

• We evaluated management’s ability to accurately estimate reasonable margins by comparing actual margins to management’s historical estimates.

Environmental Contingencies—Refer to Notes 1 and 10 to the financial statements

Critical Audit Matter Description

The Company is subject to a number of environmental laws and regulations, to potential fines or penalties assessed for alleged breaches of such laws and 
regulations and to potential claims based upon such laws and regulations. The Company records an environmental loss contingency whenever a 
contingency is probable and reasonably estimable. At December 31, 2022, the Company’s $17.7 million accrual for expected environmental costs is 
included in other accrued liabilities and long-term liabilities and represents the Company’s undiscounted estimate of costs reasonably expected to be 
incurred based on presently enacted laws and regulations, existing requirements, currently available facts, existing technology and its assessment of the 
likely remediation actions to be taken.

We identified environmental contingencies as a critical audit matter because auditing management’s estimate of the costs reasonably expected to be 
incurred for environmental contingencies involved especially subjective judgment and an increased extent of audit procedures, including the need to 
involve environmental specialists.

How the Critical Audit Matter Was Addressed in the Audit

Our audit procedures related to management’s estimate of the costs reasonably expected to be incurred for environmental contingencies included the 
following, among others:

• We tested management’s controls over environmental contingencies, including controls over the estimates of costs expected to be incurred.

• We evaluated management’s ability to accurately estimate the costs expected to be incurred by comparing actual costs incurred to historical estimates.

• With the assistance of our environmental specialists, we evaluated the reasonableness of management’s estimates of costs reasonably expected to be 

incurred by comparing the estimates to:

Business Combinations, Goodwill and Intangible Assets — Refer to Notes 1 and 4 to the financial statements

Critical Audit Matter Description

The Company’s evaluation of goodwill for impairment involves the comparison of the fair value of each reporting unit to its carrying value. The Company 
estimates the fair value using a combination of an income approach and a market-based approach. The income approach incorporates the use of cash flow 
projections and a discount rate that are developed using market participant-based assumptions. The cash-flow projections are based on Company’s best 
estimates of the long-term forecasts of the business, market prices, projected cash flows and the rate used in the discounting of those cash flows. The 
carrying value of the Warrick reporting unit exceeded the fair value as of the measurement date and, therefore, management has recognized an impairment 
of $20.5 million as of December 31, 2022. Determining the fair values of the reporting unit requires management to make significant estimates and 
assumptions related to future revenue and earnings projections.

We identified the assumptions related to estimating the amount and timing of expected future revenue and earnings used in determining the fair values of 
the Warrick reporting unit as a critical audit matter because of the significant judgments involved in 

49

 
 
 
REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM (CONTINUED)

estimating these amounts. Performing audit procedures to evaluate the reasonableness of these estimates and assumptions required a high degree of auditor 
judgment and an increased extent of effort, including the need to involve our fair value specialists.

How the Critical Audit Matter Was Addressed in the Audit

Our audit procedures related to the expected amount and timing of future revenue and earnings used to estimate the fair value of the Warrick reporting unit 
included the following, among others: 

• We tested the effectiveness of controls over their goodwill impairment evaluation, including those over the determination of fair value of the Warrick 

reporting unit, such as controls related to management’s selection of forecasts of future revenues and earnings. 

• We assessed the reasonableness of management’s forecasts of future revenues and earnings by performing inquiries of appropriate individuals outside 

of the finance organization, comparing the projections to historical results, contractual agreements, third-party industry forecasts, and internal 
communications to management and board of directors.

• With the assistance of our fair value specialists, we compared applicable industry forecasted long-term revenue growth rates to management’s 

projected revenues used within the valuation models.

• We evaluated whether the estimated future cash flows were consistent with evidence obtained in other areas of the audit.

• We evaluated management’s ability to estimate future revenues and earnings by comparing actual revenues and earnings to management’s historical 

forecasts.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. Summary of Significant Accounting Policies

In this Annual Report on Form 10-K (this “Report”), unless the context otherwise requires, references in these notes to consolidated financial 

statements to “Kaiser Aluminum Corporation,” “Kaiser,” “we,” “us,” “our,” “the Company” and “our Company” refer collectively to Kaiser Aluminum 
Corporation and its subsidiaries.

Organization and Nature of Operations. Kaiser Aluminum Corporation specializes in the production of semi-fabricated specialty aluminum mill 

products, such as aluminum plate and sheet, bare and coated coil and extruded and drawn products, for the following end market applications: (i) aerospace 
and high strength (“Aero/HS products”); (ii) beverage and food packaging (“Packaging”); (iii) general engineering (“GE products”); (iv) automotive 
(“Automotive Extrusions”); and (v) other industrial (“Other products”). Our business is organized into one operating segment. See Note 17 for additional 
information regarding our business, product and geographical area information and concentration of risk.

Principles of Consolidation and Basis of Presentation. Our consolidated financial statements include the accounts of our wholly owned subsidiaries 

and are prepared in accordance with United States generally accepted accounting principles (“GAAP”) and the rules and regulations of the Securities and 
Exchange Commission (“SEC”). Intercompany balances and transactions are eliminated. 

Use of Estimates in the Preparation of Financial Statements. The preparation of financial statements in accordance with GAAP requires the use of 
estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities known to exist as of the 
date the financial statements are published and the reported amounts of revenues and expenses during the reporting period. Uncertainties with respect to 
such estimates and assumptions are inherent in the preparation of our consolidated financial statements; accordingly, it is possible that the actual results 
could differ from these estimates and assumptions, which could have a material effect on the reported amounts of our consolidated financial position and 
results of operations. 

Supply Chain Financing. Upon our acquisition of Warrick (as defined in Note 4), we became party to several supply chain financing arrangements, 
in which we may sell certain of our customers’ trade accounts receivable to such customers’ financial institutions without recourse. We sell our undivided 
interests in certain of these receivables at our discretion when we determine that the cost of these arrangements is less than the cost of servicing our 
receivables with existing debt. Under the terms of the agreements, we retain no rights or interest, have no obligations with respect to the sold receivables 
and do not service the receivables after the sale. As such, these transactions are being accounted for as a sale. During the years ended December 31, 2022 
and December 31, 2021, we sold trade accounts receivable totaling $1,589.3 million and $1,102.8 million, respectively, related to these supply chain 
financing arrangements, of which our customers’ financial institutions applied discount fees totaling $23.3 million and $6.2 million, respectively. To the 
extent discount fees related to the sale of trade accounts receivable under supply chain financing arrangements are not reimbursed by our customers, they 
are included in Other income (expense), net. As of December 31, 2022, we had been and/or expected to be fully reimbursed by our customers for a majority 
of these discount fees.

Fair Value Measurements. We apply the fair value hierarchy established by GAAP for the recognition and measurement of certain financial assets 

and liabilities. An asset or liability’s fair value classification within the hierarchy is determined based on the lowest level input that is significant to the fair 
value measurement. In determining fair value, we utilize valuation techniques that maximize the use of observable inputs and minimize the use of 
unobservable inputs to the extent possible and consider counterparty risk in our assessment of fair value. We also review the underlying inputs that are 
significant to the fair value measurement of financial instruments to determine if a transfer among hierarchy levels is appropriate. 

Financial assets and liabilities that we measure at fair value each period include our derivative instruments and equity investments related to our 

deferred compensation plan (see Note 5 and Note 8). Additionally, we measure at fair value once each year at December 31 the plan assets of our defined 
benefit pension and postretirement plans including the Salaried VEBA (defined in Note 5). In determining the fair value of the plan assets at an annual 
period end, we utilize primarily the results of valuations supplied by the investment advisors responsible for managing the assets of each plan, which we 
independently review for reasonableness. We record our remaining financial assets and liabilities at carrying value.

 Goodwill is tested for impairment during the fourth quarter on an annual basis, as well as on an interim basis, as warranted, at the time of relevant 

events and changes in circumstances. Our evaluation of goodwill for impairment involves the comparison of the fair value of each reporting unit to its 
carrying value. We estimate the fair value of a reporting unit using a combination of an income approach and a market-based approach. Intangible asset fair 
values and useful lives are determined using the income approach valuation methodology. The income approach incorporates the use of cash flow 
projections and a discount rate that are developed using market participant-based assumptions. The cash flow projections are based on, among other factors, 
the expected future period 

57

of benefit of the asset, the various characteristics of the asset, long‑term forecasts of the business, market prices, projected cash flows and the rate used in 
discounting those cash flows. Intangible assets with definite lives are initially recognized at fair value and subsequently amortized over the estimated useful 
lives to reflect the pattern in which the economic benefits of the intangible assets are consumed. In the event the pattern cannot be reliably determined, we 
use a straight-line amortization method. Whenever events or changes in circumstances indicate that the carrying amount of the intangible assets may not be 
recoverable, the intangible assets are reviewed for impairment. See Note 4 for a discussion of our business acquisition, goodwill impairment and intangible 
asset impairment.

For a majority of our remaining non-financial assets and liabilities, which include inventories, debt issuance costs and property, plant and 
equipment, we are not required to measure their fair value on a recurring basis. However, if certain triggering events occur, an evaluation of the affected 
non-financial asset or liability will be required, which could result in a reduction to the carrying amount of such asset or liability. See “Property, Plant and 
Equipment, Net” below for a discussion of impairment charges on idled assets recorded during 2020. See Note 9 for the fair value of our Long-term debt.

Government Grants. From time to time, we receive grants from certain governmental agencies such as states and municipalities. We recognize 

government grants when we have reasonable assurance that we will comply with any conditions attached to the grant and the grant will be received. 
Government grants related to property, plant and equipment are presented as a reduction to the related asset’s carrying amount. Grants related to 
compensation for expenses already incurred or for immediate financial support with no future related costs are recognized as income in the period in which 
they are receivable. The following table presents the total government assistance recognized during the year ended December 31, 2022 (in millions of 
dollars):

To be eligible to receive and keep the full amount of the TN Fast Track and Performance grants, we must achieve: (i) minimum cumulative 
expenditures towards developmental and/or capital expenditures; (ii) a minimum number of new full-time employees; and (iii) a minimum average annual 
wage, all within seven years of our execution of the grant agreement. To be eligible to receive and keep the full amount of the IN EDGE Tax Credit, we 
must achieve: (i) minimum cumulative expenditures towards capital expenditures and (ii) a minimum number of full-time employees. 

Cash and Cash Equivalents. We consider only those short-term, highly liquid investments which, when purchased, have maturities of 90 days or less 

to be cash equivalents. Our cash equivalents consist primarily of funds in money market funds, which are classified within Level 1 of the fair value 
hierarchy.

Restricted Cash. We are required to keep on deposit certain amounts that are pledged or held as collateral relating to workers’ compensation and 
other agreements. We account for such deposits as restricted cash (see Note 16). From time to time, such restricted funds could be returned to us or we 
could be required to pledge additional cash.

Available for Sale Securities. We have historically accounted for investments in certain marketable debt securities with maturities of greater than 90 

days as available for sale securities. Such securities were recorded at fair value with net unrealized gains and losses, net of income taxes, reflected in 
Accumulated other comprehensive income (loss) as a component of Stockholders’ equity.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Realized gains and losses from the sale of available for sale securities, if any, were determined on a specific identification basis. We settled all outstanding 
available for sale securities during the year ended December 31, 2020.  

Trade Receivables and Allowance for Credit Losses. Trade receivables primarily consist of amounts billed to customers for products sold. Accounts 

receivable are generally due within 30 to 90 days. For the majority of our receivables, we establish an allowance for credit losses based upon collection 
experience and other factors including, but not limited to, customer credit ratings, bankruptcy filings, published or estimated credit default rates, age of 
receivables, expected loss rates and collateral exposures. On certain other receivables where we are aware of a specific customer’s inability or reluctance to 
pay, an allowance for credit losses is established against amounts due, to reduce the net receivable balance to the amount we reasonably expect to collect. 
However, if circumstances change, our estimate of the recoverability of accounts receivable could be different. Circumstances that could affect our 
estimates include, but are not limited to, customer credit issues and general economic conditions. Accounts are written off once deemed to be uncollectible. 
Any subsequent cash collections relating to accounts that have been previously written off are typically recorded as a reduction to total bad debt expense in 
the period of payment. Write-offs for 2022, 2021 and 2020 were immaterial to our consolidated financial statements.

Inventories. Inventories are stated at the lower of cost or market value. Finished products, work-in-process and raw material inventories are stated on 

the last-in, first-out (“LIFO”) basis. At December 31, 2022 and December 31, 2021, the cost of our inventory on a first-in, first-out (“FIFO”) basis, which 
approximates the current replacement cost, exceeded its stated LIFO value by $84.6 million and $137.1 million, respectively. Other inventories are stated 
on the FIFO basis and consist of operating supplies, which are materials and supplies to be consumed during the production process. Inventory costs consist 
of material, labor and manufacturing overhead, including depreciation. Abnormal costs, such as idle facility expenses, freight, handling costs and spoilage, 
are accounted for as current period charges. See Note 2 for the components of inventories.

Replacement Parts. Replacement parts consist of preventative maintenance and capital spare parts, which are stated on the FIFO basis. Replacement 
parts are recorded within Prepaid expenses and other current assets or Other assets depending on whether or not the expected utilization of the replacement 
parts is to occur within the next 12 months.

Property, Plant and Equipment, Net. Property, plant and equipment, net, is recorded at cost and includes construction in progress (see Note 2). 

Property, plant and equipment acquired in the Warrick (as defined in Note 4) acquisition was recorded at fair value as of the date of acquisition. Interest 
related to the construction of qualifying assets is capitalized as part of the construction costs (see Note 9).

Depreciation is computed using the straight-line method at rates based on the estimated useful lives of the various classes of assets. Depreciable 
finance lease assets and leasehold improvements are amortized on a straight-line basis over the shorter of the estimated useful lives of the assets or the lease 
term. The estimated useful lives are as follows:

Land improvements
Buildings and leasehold improvements
Machinery and equipment
Depreciable finance lease assets

Range
(in years)
1-25
2-45
1-22
2-120

Depreciation expense is not included in Cost of products sold, but is included in Depreciation and amortization.

Property, plant and equipment are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of the 

asset or group of assets may not be recoverable. We regularly assess whether events and circumstances with the potential to trigger impairment have 
occurred and rely on a number of factors, including operating results, business plans, economic projections and anticipated future cash flow, to make such 
assessments. We use an estimate of the future undiscounted cash flows of the related asset or asset group over the estimated remaining life of such asset or 
asset group in measuring whether the asset or asset group is recoverable.

There were no impairment charges in 2022 and 2021. We recorded impairment charges of $0.5 million in 2020 to reflect the scrap value of idled 
assets we determined not to deploy for future use. Asset impairment charges are included in Other operating charges (income), net, in our Statements of 
Consolidated (Loss) Income.

We classify assets as held for sale only when an asset is being actively marketed and expected to sell within 12 months. Assets held for sale are 

initially measured at the lesser of the assets’ carrying amount and the fair value less costs to sell.

Cloud Computing Implementation Costs. We defer implementation costs associated with a software hosting arrangement that meets the definition of 
a service contract. We recognize these deferred costs within Prepaid expenses and other current assets and within Other assets on our Consolidated Balance 
Sheets. When the project is placed into service, we amortize the deferred implementation costs over the term of the hosting arrangement inclusive of 
expected renewal periods to the same line item in the Statements of Consolidated (Loss) Income as the underlying arrangement. The following table 
summarizes the total deferred implementation costs and accumulated amortization related to the hosted cloud computing software for our enterprise 
resource planning system refresh project (in millions of dollars):

We recorded amortization expense of $1.0 million, $0.1 million and zero in 2022, 2021 and 2020, respectively.

Leases. We determine whether an agreement is a lease at inception. We have operating and finance leases for equipment and real estate that 
primarily have fixed lease payments. For purposes of calculating lease liabilities, options to extend or terminate a lease are included within the lease term 
when it is reasonably certain that we will exercise such options. Short-term leases with an initial term of 12 months or less are not recorded on our 
Consolidated Balance Sheets.

As most of our leases do not provide an implicit rate, we use information available at the lease commencement date in determining an incremental 

borrowing rate when calculating our right-of-use lease assets and liabilities. In determining the inputs to the incremental borrowing rate calculation, we 
make judgments about the value of the leased asset, our credit rating and the lease term, including the probability of our exercising options to extend or 
terminate the underlying lease. Additionally, we make judgments around contractual asset substitution rights in determining whether a contract contains a 
lease.

We have lease agreements with lease and non-lease components, which are generally accounted for separately. These non-lease components include 
items such as common area maintenance, taxes and insurance for our real estate leases, as well as maintenance charges related to our equipment leases. We 
have, however, applied the practical expedient within Accounting Standards Update (“ASU”) No. 2016-02, Leases (Topic 842): Amendments to the 
Financial Accounting Standards Board Accounting Standards Codification (“ASU 2016-02”), to not separate lease and non-lease components to our 
embedded supply system equipment leases and have therefore accounted for both lease and non‑lease components in determining the lease assets and 
liabilities.

Many of our equipment leases contain clauses that require us to return the equipment with certain functionality intact. We account for these costs as 

residual value guarantees when the guarantee becomes probable of being owed. Our lease agreements do not contain any material restrictive covenants.

Derivative Financial Instruments. Consistent with guidelines established by management and approved by our Board of Directors, we use derivative 

financial instruments to mitigate our exposure to changes in the market price of aluminum, certain alloying metals, energy and, to a lesser extent, foreign 
currency exchange rates. We do not use derivative financial instruments for trading or other speculative purposes. Hedging transactions are executed 
centrally on behalf of all of our operations to minimize transaction costs, monitor consolidated net exposures and allow for increased responsiveness to 
changes in market factors.

We reflect the fair value of all of our derivative instruments on our Consolidated Balance Sheets. The fair value of hedges settling within one year is 

included in Prepaid expenses and other current assets or Other accrued liabilities. The fair value of hedges settling beyond one year is included in Other 
assets or Long-term liabilities. Cash flows related to all of our derivative instruments are reported in our Statements of Consolidated Cash Flows within the 
same category as the items being hedged. See Note 8 for additional information on our derivative financial instruments.

Self Insurance of Workers’ Compensation and Employee Healthcare Liabilities. We self-insure the majority of the costs of workers’ compensation 

benefits and employee healthcare benefits and rely on insurance coverage to protect us from large losses on individual claims. Workers’ compensation 
liabilities are based on a combination of estimates for: (i) incurred-but-not-reported claims 

60

 
 
 
 
   
 
 
   
   
 
 
Notes Index

KAISER ALUMINUM CORPORATION AND SUBSIDIARY COMPANIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

and (ii) the ultimate expense of incurred claims. Such estimates are based on judgment, using our historical claims data and information and analysis 
provided by actuarial and claims advisors, our insurance carriers and other professionals. As of December 31, 2020, we revised our methodology of 
calculating our estimated workers’ compensation liabilities from a discounted basis to an undiscounted basis, resulting in a charge of $0.6 million. Accrued 
liabilities for employee healthcare benefits, which are estimates of unpaid incurred medical and prescription drug costs as provided by our healthcare 
administrators, were $7.7 million and $9.0 million at December 31, 2022 and December 31, 2021, respectively.

Debt Issuance Costs. Costs incurred in connection with debt financing are deferred and amortized over the estimated term of the related borrowing. 
Such amortization is included in Interest expense in our Statements of Consolidated (Loss) Income. Unamortized issuance costs are presented within Long-
term debt on our Consolidated Balance Sheets (see Note 9).

Conditional Asset Retirement Obligations (“CAROs”). We have CAROs at several of our manufacturing facilities. Our CAROs can be separated into 

two primary categories: (i) legal obligations related to the removal and disposal of asbestos and (ii) asset retirement obligations related to future lease 
terminations. The majority of our CAROs relate to the first category and consist of incremental costs that would be associated with the removal and 
disposal of asbestos (all of which is believed to be fully contained and encapsulated within walls, floors, roof, piping or equipment insulation) of certain of 
our older facilities if such facilities were to undergo major renovation or be demolished. We estimate incremental costs for special handling, removal and 
disposal costs of materials that may or will give rise to CAROs and then discount the expected costs back to the current year using a credit-adjusted, risk-
free rate. When it is unclear when or if CAROs will be triggered, we use probability weighting for possible timing scenarios to determine the probability-
weighted liability amounts that should be recognized in our consolidated financial statements (see Note 10).

Environmental Contingencies. With respect to environmental loss contingencies, we record a loss contingency whenever a contingency is probable 
and reasonably estimable (see Note 10). Accruals for estimated losses from environmental remediation obligations are generally recognized no later than 
the completion of the remedial feasibility study. Such accruals are adjusted as information develops or circumstances change. Costs of future expenditures 
for environmental remediation obligations are not discounted to their present value. Accruals for expected environmental costs are included in Other 
accrued liabilities or Long-term liabilities, as appropriate (see Note 2). Environmental expense relating to continuing operations is included in Cost of 
products sold excluding depreciation and amortization and other items (“Cost of products sold” or “COGS”) in our Statements of Consolidated (Loss) 
Income. Environmental expense relating to non-operating locations is included in Selling, general, administrative, research and development (“SG&A and 
R&D”) in our Statements of Consolidated (Loss) Income.

Revenue Recognition. We recognize revenue as we fulfill our performance obligations and transfer control of products to our customers. For 
products that have an alternative use and/or for which we do not have an enforceable right to payment (including a reasonable profit) during the production 
process, we recognize revenue at a point in time. For products that have no alternative use and for which we have an enforceable right to payment 
(including a reasonable profit) throughout the production process, we recognize revenue over time. In general, revenue recognized over time primarily 
relates to our Aero/HS products and our Automotive Extrusions with the remainder of our products recognized at a point in time. In limited circumstances, 
we have concluded that we are an agent in certain Packaging end market arrangements. For these transactions, revenue has been recognized on a net basis.

For the majority of our business, contracts with customers begin when we acknowledge a purchase order for a specific customer order of product to 

be delivered in the near term. These purchase orders are short term in nature, although they may reference a longer term “blanket purchase order” or a 
“terms and conditions” agreement, both of which may span multiple years. For revenue recognized at a point in time, transfer of control usually occurs 
upon shipment or upon customer receipt of the product, depending on shipping terms. For contracts recognized over time, control transfer occurs 
incrementally during our production process as progress is made on fulfilling the performance obligation. We use the input method of determining our 
progress, capturing direct costs beginning at the point that billet or cast ingot is introduced into production at either the extrusion phase or the rolling phase, 
respectively. We believe the input method more accurately reflects the transfer of control as it represents the best information available of work completed 
to date for which we have an enforceable right to payment. For products in production, we recognize revenue using estimates of the cost incurred to date 
plus a reasonable margin. As the duration of our contracts for accounting purposes is typically less than one year, we do not present quantitative 
information about the aggregate transaction price allocated to unsatisfied performance obligations at the end of the reporting period.

We adjust the amount of revenue recognized on all products, regardless of timing of revenue recognition, for variable price consideration, which 

could include metal market price adjustments, volume rebates and sales discounts. We estimate rebate and discount values based on forecasted order data 
and historical payment trends for specific customers, adjusted as necessary at each reporting period. Accounts receivable is recorded when our right to 
consideration becomes unconditional. Payment terms for a majority of our domestic customers are 30 days after invoice date. To accommodate shipping 
time to overseas locations, payment 

61

 
Notes Index

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

terms for foreign customers are typically several weeks longer than domestic terms. As such, we do not adjust the promised amount of consideration for the 
effects of a significant financing component as we do not expect the period between the transfer of control of products to our customers and receipt of 
payment will be greater than one year.

Contract assets primarily relate to our enforceable right to consideration for work completed but not billed at the reporting date on contracts for 
products recognized over time. Contract assets also include amounts related to our contractual right to consideration for finished goods recognized over 
time that were in transit as of period end.

Incremental Costs of Obtaining a Contract. We expense the costs of obtaining a contract as incurred as the amortization period of the asset that we 

otherwise would have recognized is one year or less.

Shipping and Handling Activities. We account for shipping and handling activities that occur after the customer has obtained control of a product as 

fulfillment activities (i.e., an expense) rather than as a promised service (i.e., a revenue element).

Advertising Costs. Advertising costs, which are included in SG&A and R&D, are expensed as incurred. We had no advertising costs for 2022, and 

$0.1 million and $0.2 million in 2021 and 2020, respectively.

Research and Development Costs. Research and development costs, which are included in SG&A and R&D, are expensed as incurred. Research and 

development costs for 2022, 2021 and 2020 were $9.3 million, $9.3 million and $9.1 million, respectively.

Major Maintenance Activities. All major maintenance costs are accounted for using the direct expensing method.

Stock-Based Compensation. Stock-based compensation in the form of service-based awards is provided to executive officers, certain employees and 

non-employee directors and is accounted for at fair value. We measure the cost of services received in exchange for an award of equity instruments based 
on the grant-date fair value of the award and the number of awards expected to ultimately vest. The grant-date fair value is determined based on the stock 
price on the date of grant, adjusted for expected dividends or dividend equivalents to be paid during the vesting period.

We also grant performance-based awards to executive officers and other key employees. The methodology used to value these performance-based 

awards is based on the nature of the performance conditions within those awards. Awards that are subject to performance conditions pertaining to total 
shareholder return (market-based awards) are valued on the date of grant using a Monte Carlo valuation model. The key assumptions in applying this 
model are an expected volatility and a risk-free interest rate. Awards with certain other performance conditions (non-market-based awards) are valued 
based on our stock price at the date of grant. Our non‑market-based awards have performance conditions pertaining to our cost performance and adjusted 
EBITDA margin performance, which is measured by our adjusted earnings before interest, taxes, depreciation and amortization (“Adjusted EBITDA”) as a 
percentage of Conversion Revenue, which is Net sales less the Hedged Cost of Alloyed Metal. As used in this discussion, “Hedged Cost of Alloyed Metal” 
is the cost of aluminum at the average Midwest Transaction Price (“Midwest Price”) plus the cost of alloying elements and any realized gains and/or losses 
on settled hedges related to the metal sold in the referenced period. Holders of performance-based awards receive a one-time payment at the time of 
issuance of vested shares based on the total dividends they would have received if the vested shares had been held of record from the date of grant through 
the date of issuance. See Note 7 for more information on our stock-based compensation.

The cost of service-based awards, including time-vested restricted stock and performance shares, is recognized as an expense over the requisite 

service period of the award on a straight-line basis. Adjustments to expense related to forfeitures are recorded in the period in which they occur. For 
performance shares with performance conditions pertaining to our cost performance and Adjusted EBITDA margin performance, the related expense is 
updated quarterly by adjusting the estimated number of shares expected to vest based on the most probable outcome of the performance condition (see Note 
7).

Adoption of New Accounting Pronouncements

ASU No. 2021-10, Government Assistance (Topic 832): Disclosures by Business Entities about Government Assistance (“ASU 2021-10”) was 
issued in November 2021. Under ASU 2021-10, the accounting entities with transactions with a government that are accounted for by analogy to a grant or 
contribution accounting model are required to annually disclose certain information regarding the transaction including: (i) nature and related accounting 
policy used; (ii) line items on the balance sheet and income statement affected by the transactions; (iii) amounts applicable to each line item; and (iv) 
significant terms and conditions. We adopted ASU 2021-10 during the year ended December 31, 2022 using a prospective approach. See “Government 
Grants” above for additional information.

In March 2020, the Financial Accounting Standards Board (“FASB”) issued ASU 2020-04, Reference Rate Reform (Topic 848): Facilitation of the 
Effects of Reference Rate Reform on Financial Reporting (“ASU 2020-04”) and also issued subsequent amendments to the initial guidance (collectively, 
“Topic 848”). Topic 848 is effective for all entities as of March 12, 2020 through December 31, 2024 and provides optional guidance for contract 
modifications and certain hedging relationships associated with the transition from reference rates that are expected to be discontinued. During the quarter 
ended June 30, 2022, we completed the transition of our customers’ supply chain financing contracts from the London Interbank Offered Rate (“LIBOR”) 
to Term Secured Overnight Financing Rate (“Term SOFR”). Our adoption of Topic 848 did not have a material impact on our consolidated financial 
statements.

Business Combinations. On March 31, 2021, we acquired Alcoa Warrick LLC and certain assets comprising the aluminum casting and rolling mill 
facility located in Warrick County, Indiana (collectively, “Warrick”) for a final purchase consideration of $609.2 million. Warrick is a leading producer of 
bare and coated aluminum coil used for can stock applications in the beverage and

food packaging industry in North America. The transaction provided us with non-cyclical end market diversification and re-entry into the packaging end 
market. 

Goodwill. In conjunction with our acquisition of Warrick, we added $20.5 million of goodwill after allocating the consideration paid, net of cash 

received to all other identifiable assets. The goodwill reflected the value we expected from our re-entry into the Packaging end market and our assembled 
workforce. In conjunction with our annual testing and due to downward revisions in forecasted operating margins as a result of supply chain challenges, 
inflationary cost pressures and manufacturing inefficiencies, we determined that the carrying value of Warrick exceeded its fair value, and we recognized 
an impairment charge of $20.5 million for the year ended December 31, 2022 within Operating income in the Statements of Consolidated (Loss) Income. 
We estimated the fair value of Warrick using a combination of an income approach and a market-based approach. The income approach incorporated the 
use of cash flow projections and a discount rate that is developed using market participant-based assumptions. The cash flow projections are based on our 
best estimates of the long-term forecasts of the business, market prices, projected cash flows and the rate used in the discounting of those cash flows. As 
goodwill is deductible for tax purposes, the deferred tax effects were included in the impairment charge and income tax provision. The following table 
presents the changes in the carrying value of our goodwill (in millions of dollars):

We sponsor defined contribution 401(k) savings plans for certain hourly and salaried employees. Employees may contribute a portion of their 
compensation to the plans and we match a specified percentage of these contributions in equivalent form of the investments elected by the employee. 
Additionally, we make fixed annual contributions for certain hourly and salaried employees in varying amounts depending on hire date.

Deferred Compensation Plan

We sponsor a non-qualified, unfunded, unsecured plan of deferred compensation for certain employees who would otherwise suffer a loss of benefits 

under our defined contribution plan as a result of the limitations imposed by the Internal Revenue Code of 1986. Despite the plan being an unfunded plan, 
we make an annual contribution to a rabbi trust to fulfill future funding obligations, as contemplated by the terms of the plan. The assets in the trust are 
held in various investment funds at certain registered investment companies (see discussion below in “Fair Value of Plan Assets”) and are at all times 
subject to the claims of our general creditors. No participant has a claim to any assets of the trust; however, participants are eligible to receive distributions 
from the trust subject to vesting and other eligibility requirements. Offsetting liabilities relating to the deferred compensation plan are included within 
Other accrued liabilities and Long-term liabilities. Assets in the trust are accounted for as equity investments with changes in fair value recorded within 
Other income (expense), net (see Note 13).

Other Benefits

We provide other benefits for certain members of senior management, including certain of our named executive officers, related to terminations of 

employment in specified circumstances, including in connection with a change in control, by us without cause and by the executive officer with good 
reason.

Defined Benefit Plans

Pension. We sponsor defined benefit pension plans for certain hourly bargaining unit employees and salaried employees. Pension benefits generally 

depend on length of service, job grade and remuneration. Substantially all benefits are paid through pension trusts that are sufficiently funded to ensure that 
all plans can pay benefits to retirees as they become due. We use a December 31 measurement date for our pension plans.

OPEB. We sponsor a healthcare and life insurance postretirement benefit plan (“OPEB”) covering certain eligible retirees. Generally, the medical 

plans are unfunded and pay a percentage of medical expenses, reduced by deductibles and other coverage. Life insurance benefits are generally provided by 
insurance contracts. We use a December 31 measurement date for our OPEB plan.

Salaried VEBA Postretirement Obligation. Certain retirees who retired prior to 2004 and certain employees who were hired prior to February 2002 

and have subsequently retired or will retire with the requisite age and service, along with their surviving spouses and eligible dependents, are eligible to 
participate in a voluntary employees’ beneficiary association (“VEBA”) that provides healthcare cost, medical cost and long-term care insurance cost 
reimbursement benefits (“Salaried VEBA”). The accumulated postretirement benefit obligation (“APBO”) for the Salaried VEBA was computed based on 
the level of benefits being provided. Since

KAISER ALUMINUM CORPORATION AND SUBSIDIARY COMPANIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

the Salaried VEBA pays out a fixed annual amount to its participants, no future cost trend rate increase was assumed in computing the APBO for the 
Salaried VEBA. 

We have an ongoing obligation with no express termination date to make variable cash contributions up to a maximum of $2.9 million to the 

Salaried VEBA. The Salaried VEBA assets were invested in various managed funds based on information we received from the trustee of the Salaried 
VEBA. Our variable payment, if any, is treated as a funding/contribution policy and not counted as a Salaried VEBA asset at the accrual date for actuarial 
purposes. There was no required accrual for variable contributions as of December 31, 2022. There was no payment made with respect to 2021 during the 
first quarter of 2022. We account for the Salaried VEBA as a defined benefit plan in our financial statements using a December 31 measurement date.

Fair Value of Plan Assets. The plan assets of our pension plans and the Salaried VEBA are measured annually on December 31 and reflected in our 

Consolidated Balance Sheets at fair value. In determining the fair value of the plan assets at an annual period end, we utilize primarily the results of 
valuations supplied by the investment advisors responsible for managing the assets of each plan, which we independently review for reasonableness. With 
respect to the Salaried VEBA, the investment advisors providing the valuations are engaged by the Salaried VEBA trustees. 

Certain plan assets are valued based upon unadjusted quoted market prices in active markets that are accessible at the measurement date for 
identical, unrestricted assets (e.g., liquid securities listed on an exchange). Such assets are classified within Level 1 of the fair value hierarchy. The 
remainder of plan assets are valued based on the net asset value (“NAV”) of shares held by the plans at year end using the NAV practical expedient.

6. Multiemployer Pension Plans

Overview. We contribute to multiemployer defined benefit pension plans under the terms of collective bargaining agreements that cover our union-

represented employees at certain facilities. At December 31, 2022, approximately 35% of our total employees were union-represented employees at 
facilities participating in these multiemployer pension plans. We currently estimate that contributions will range from $4.0 million to $6.0 million in 2023.

The risks of participating in these multiemployer plans are different from single-employer plans in the following aspects:

•

•

•

Assets contributed to the multiemployer plan by one employer may be used to provide benefits to employees of other participating 
employers.

If a participating employer stops contributing to the plan, the unfunded obligations of the plan may be borne by the remaining participating 
employers.

If we choose to stop participating in any of our multiemployer plans, we may be required to pay those plans an amount based on the 
underfunded status of the plan, referred to as a withdrawal liability.

The zone status is based on information that we received from the plan and is certified by the plan’s actuary. Among other factors, plans in the green 
zone are at least 80% funded.
The “FIP/RP Status Pending/Implemented” column indicates if a Financial Improvement Plan (“FIP”) or a Rehabilitation Plan (“RP”) is either 
pending or has been implemented for the plan under the Pension Protection Act.
We are party to three collective bargaining agreements with the United Steel, Paper and Forestry, Rubber, Manufacturing, Energy, Allied Industrial 
and Service Workers International Union, AFL-CIO, CLC (“USW”) that require contributions to the Steelworkers Pension Trust. As of December 
31, 2022, USW collective bargaining agreements covering employees at our Newark, Ohio (“Newark”) and Spokane, Washington (“Trentwood”) 
facilities covered 86% of our USW-represented employees and expire in September 2025. Our monthly contributions per hour worked by each 
bargaining unit employee at our Newark and Trentwood facilities were (in whole dollars) $1.75 in 2022. The union contracts covering employees at 
our Richmond, Virginia facility and Florence, Alabama facility cover 11% and 3% of our USW-represented employees, respectively, and expire in 
November 2026 and March 2026, respectively.
Other Funds consists of plans that are not individually significant.

We were not listed in any of the plans’ Forms 5500 or the Canada-Wide Industrial Pension Plan financial statements as providing more than 5% of 

the total contributions for any of the plan years disclosed. At December 31, 2022, financial statements and Forms 5500 were not available for the plan year 
ending in 2022. Further, there were no significant changes to the number of employees covered by our multiemployer plans that would affect the period-to-
period comparability of the contributions for the years presented.

7. Employee Incentive Plans

Short-Term Incentive Plans (“STI Plans”)

We have annual short-term incentive compensation plans for senior management and certain other employees payable at our election in cash, shares 

of common stock or a combination of cash and shares of common stock. Amounts earned under STI Plans are based on our Adjusted EBITDA, modified 
for certain safety, quality, delivery, cost and individual performance factors. The Adjusted EBITDA targets are determined based on the return on adjusted 
net assets. Most of our production facilities have similar programs for both hourly and salaried employees. Additionally, we have discretionary bonus 
programs that allow for management to incentivize employees based on performance. As of December 31, 2022, we had a liability of $4.1 million recorded 
within Accrued salaries, wages and related expenses for estimated probable future payments relating to the 12-month performance period of our 2022 STI 
Plans and discretionary programs.

Long-Term Incentive Programs (“LTI Programs”)

General. Executive officers and other key employees of the Company, as well as non-employee directors of the Company, are eligible to participate 
in the Kaiser Aluminum Corporation 2021 Equity and Incentive Compensation Plan (“2021 Plan”). The 2021 Plan was approved by stockholders on June 
3, 2021 and replaced and succeeded, in its entirety, the Kaiser Aluminum Corporation Amended and Restated 2016 Equity and Performance Incentive Plan, 
except with regard to awards previously granted thereunder that continued to be outstanding. At December 31, 2022, 612,882 shares were available for 
awards under the 2021 Plan. 

Non-Vested Common Shares and Restricted Stock Units. We grant non-vested common shares (“RSAs”) to our non-employee directors and 
restricted stock units (“RSUs”) to our executive officers and other key employees. The RSUs have rights similar to the rights of RSAs and each RSU that 
becomes vested entitles the recipient to receive one common share, for which we issue new shares of our common stock upon vesting under the 2021 Plan, 
or a cash amount equaling the value of one common share. The service period is generally one year for RSAs granted to non-employee directors and three 
years for RSUs granted to executive officers and other key employees. 

The following table summarizes activity relating to RSAs and RSUs for the year ended December 31, 2022:

Performance Shares. We grant performance shares to executive officers and other key employees that vest upon the achievement of specified market 

or internal performance goals. Performance goals can include: (i) our achieving a total shareholder return (“TSR”) compared to the TSR of a specified 
group of peer companies over a three-year performance period (“TSR-Based Performance Shares”); (ii) achieving targeted improvements to our total 
controllable cost performance over a three-year performance period; and/or (iii) achieving targeted improvements to our Adjusted EBITDA margin 
performance, measured by our Adjusted EBITDA as a percentage of Conversion Revenue, over a three-year performance period. Each performance share 
that becomes vested and earned entitles the recipient to receive one common share or a cash amount equaling the value of one common share. The number 
of performance shares that may be earned and result in the issuance of cash or common shares ranges between 0% to 200% of the target number of 
underlying performance shares, which is approximately 55% to 70% of individual long-term incentive plan target amounts.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Participants may elect to have us withhold common shares to satisfy minimum statutory tax withholding obligations arising in connection with the 

vesting of RSAs, RSUs and performance shares. We cancel any such shares withheld on the applicable vesting dates or earlier dates when service 
requirements are satisfied, which correspond to the times at which income to the employee is recognized. When we withhold these common shares, we are 
required to remit to the appropriate taxing authorities the fair value of the shares withheld as of the vesting date. The withholding of common shares by us 
could be deemed a purchase of the common shares. See Statements of Consolidated Stockholders’ Equity for details on cancellation of shares to cover 
employees’ tax withholdings upon vesting of non-vested shares.

8. Derivatives, Hedging Programs and Other Financial Instruments

Overview. In conducting our business, we enter into derivative transactions, including forward contracts and options, to limit our exposure to: (i) 
metal price risk related to our sale of fabricated aluminum products and the purchase of metal, including primary and scrap, or recycled, aluminum, our 
main raw material, and certain alloys used as raw material for our fabrication operations; (ii) energy price risk relating to fluctuating prices of natural gas 
and electricity used in our production processes; and (iii) foreign currency requirements with respect to cash commitments for equipment purchases and/or 
other agreements denominated in foreign currency. We do not use derivative financial instruments for trading or other speculative purposes. Hedging 
transactions are executed centrally on behalf of all of our operations to minimize transaction costs, monitor consolidated net exposures and allow for 
increased responsiveness to changes in market factors.

Our derivative activities are overseen by a committee (“Hedging Committee”), which is composed of our chief executive officer, chief financial 
officer, chief accounting officer, treasurer and other officers and employees selected by the chief executive officer. The Hedging Committee meets regularly 
to review commodity price exposure, derivative positions and strategy. Management reviews the scope of the Hedging Committee’s activities with our 
Board of Directors.

We are exposed to counterparty credit risk on all of our derivative instruments, which we manage by monitoring the credit quality of our 
counterparties and allocating our hedging positions among multiple counterparties to limit exposure to any single entity. Our counterparties are major 
investment grade financial institutions or trading companies, and our hedging transactions are governed by negotiated International Swaps and Derivatives 
Association Master Agreements, which generally require collateral to be posted by our counterparties above specified credit thresholds which may adjust 
up or down, based on increases or decreases in counterparty credit ratings. As a result, we believe the risk of loss is remote and contained. The aggregate 
fair value of our derivative instruments that were in a net liability position was $3.3 million and zero at December 31, 2022 and December 31, 2021, 
respectively, and we had no collateral posted as of those dates.

Additionally, our firm-price customer sales commitments create incremental customer credit risk related to metal price movements. Under certain 

circumstances, we mitigate this risk by periodically requiring cash collateral from them, which we classify as deferred revenue and include as a component 
of Other accrued liabilities. We had no cash collateral posted from our customers at both December 31, 2022 and December 31, 2021. For more 
information about concentration risks concerning customers and suppliers, see Note 17.

We designate as cash flow hedges forward swap contracts for aluminum, energy and, from time to time, zinc and copper (“Alloying Metals”) used in 

our fabrication operations and foreign currency forward contracts for equipment and services for which payments are due in foreign currency. Unrealized 
gains and losses associated with our cash flow hedges are deferred in Other comprehensive (loss) income, net of tax, and reclassified to COGS when such 
hedges settle or when it is probable that the original forecasted transactions will not occur by the end of the originally specified time period. See Note 11 
for the total amount of gain or loss on derivative instruments designated and qualifying as cash flow hedging instruments and fair value hedging 
instruments that was reported in Accumulated other comprehensive income (loss) (“AOCI”), as well as the related reclassifications into earnings and tax 
effects. Cumulative gains and losses related to cash flow hedges are reclassified out of AOCI and recorded within COGS when the associated hedged 
commodity purchases impact earnings.

Aluminum Hedges. Our pricing of fabricated aluminum products is generally intended to lock in our Conversion Revenue (representing our value 
added from the fabrication process) and to pass through aluminum price fluctuations to our customers. For some of our higher margin products sold on a 
spot basis, the pass through of aluminum price movements can sometimes lag by as much as several months, with a favorable impact to us when aluminum 
prices decline and an adverse impact to us when aluminum

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

prices increase. Additionally, in certain instances, we enter into firm-price arrangements with our customers for stipulated volumes to be delivered in the 
future. Because we generally purchase primary and secondary aluminum on a floating price basis, the lag in passing through aluminum price movements to 
customers on some of our higher margin products sold on a spot basis and the volume that we have committed to sell to our customers under a firm-price 
arrangement create aluminum price risk for us. We use third-party hedging instruments to limit exposure to aluminum price risk related to the aluminum 
pass through lag on some of our products and firm-price customer sales contracts.

Alloying Metals Hedges. We are exposed to risk of fluctuating prices for alloying metals used as raw materials in our fabrication operations. We, 
from time to time, in the ordinary course of business, enter into hedging transactions and/or physical delivery commitments with third parties to mitigate 
our risk from fluctuations in certain alloying metals prices that are not passed through pursuant to the terms of our customer contracts.

Energy Hedges. We are exposed to risk of fluctuating prices for natural gas and electricity. We, from time to time, in the ordinary course of 
business, enter into hedging transactions and/or physical delivery commitments with third parties to mitigate our risk from fluctuations in natural gas and 
electricity prices that are not passed through pursuant to the terms of our customer contracts.

The following table summarizes the percentage of our expected variable priced purchases of metal alloys and energy for which we have executed 

derivative and/or physical delivery commitments in place to reduce price fluctuations for the next five years as of December 31, 2022:

Foreign Currency Hedges. We are exposed to foreign currency exchange risk related to certain supply and service agreements with vendors for 

which payments are due in foreign currency. We, from time to time, in the ordinary course of business, use foreign currency forward contracts in order to 
mitigate the exposure to currency exchange rate fluctuations related to these purchases.  

Fair Value Hedges

We are exposed to foreign currency exchange risk related to firm-price commitments for equipment purchases from foreign manufacturers. We, 

from time to time, in the ordinary course of business, use third-party hedging instruments to mitigate our exposure to currency exchange rate fluctuations 
on these purchases and designate such hedging instruments as fair value hedges. Gain or loss related to components excluded from the assessment of 
effectiveness from these fair value hedges is first recognized in AOCI and subsequently reclassified to Depreciation and amortization on a straight-line 
basis over the term of the hedge. Gain or loss on the hedged item (e.g., equipment purchase firm commitments) and the remaining gain or loss on the fair 
value hedge is recorded within Depreciation and amortization in the period that the gain or loss occurs. Any difference between the change in the fair value 
of the excluded component and amounts recognized in income on a straight-line basis over the term of the hedge is recognized in AOCI.

Non-Designated Hedges of Operational Risks

From time to time, we enter into commodity contracts that are not designated as hedging instruments to mitigate certain short‑term commodity 

impacts, as identified. The gain or loss on these derivatives is recognized within COGS.

The adjustments to accretion expense had a $0.01 impact on the basic and diluted net income per share for 2020. 

The estimated fair value of CARO liabilities were based upon the application of a weighted-average credit-adjusted risk-free rate of 8.23% and 
8.70% at December 31, 2022 and December 31, 2021, respectively. CAROs are included in Other accrued liabilities or Long-term liabilities, as appropriate.

Environmental Contingencies. We are subject to a number of environmental laws and regulations, potential fines or penalties assessed for alleged 

breaches of such laws and regulations and potential claims based upon such laws and regulations. We are also subject to legacy environmental 
contingencies related to activities that occurred at operating facilities prior to July 6, 2006, which represent the majority of our environmental accruals. The 
status of these environmental contingencies are discussed below. We have established procedures for regularly evaluating environmental loss contingencies. 
Our environmental accruals represent our undiscounted estimate of costs reasonably expected to be incurred based on presently enacted laws and 
regulations, currently available facts, existing requirements, existing technology and our assessment of the likely remediation actions to be taken.

We continue to pursue remediation activities, primarily to address the historical use of oils containing polychlorinated biphenyls (“PCBs”) at our 
Trentwood facility. Our remediation efforts are in collaboration with the Washington State Department of Ecology (“Ecology”), to which we submitted a 
feasibility study in 2012 of remediation alternatives and from which we received permission to begin certain remediation activities pursuant to a signed 
work order. We have completed a number of sections of the work plan and have received satisfactory completion approval from Ecology on those sections. 
In cooperation with Ecology, we constructed an experimental treatment facility to determine the treatability and evaluate the feasibility of removing PCBs 
from ground water under the Trentwood facility. In 2015, we began treatment operations involving a walnut shell filtration system, which we optimized for 
maximum PCB capture during 2020. Furthermore, based on advancements in technology, we signed an Amended Agreed Order with

Ecology in 2020 to evaluate and implement new technologies for PCB removal from groundwater on a pilot basis. The primary technology we are 
evaluating is Ultraviolet Light Advanced Oxidation Process (the “UV Process”). During the quarter ended December 31, 2022, we increased our 
environmental accrual by $3.0 million based on a minimum cost estimate to implement the UV Process on a larger scale as part of our milestone 
submission to Ecology. As the long-term success of the UV Process cannot be reasonably determined at this time, it is possible we may need to make 
upward adjustments to our related accruals and cost estimates as the long-term results become available.

Pursuant to a consent agreement with the Ohio Environmental Protection Agency (“OEPA”), we initiated an investigational study of our Newark 

facility related to historical on-site waste disposal. During the quarter ended December 31, 2018, we submitted our remedial investigation study to the 
OEPA for review and approval. The final remedial investigation report was approved by the OEPA during the quarter ended December 31, 2020. We are 
currently preparing the required feasibility study, which we expect to submit to the OEPA for review during the quarter ending September 30, 2023. The 
actual and final remediation cost estimates will not be fully determinable until the feasibility study has been accepted by the OEPA and the selected 
remediation design work plans are completed, which we expect to occur in the next 11 to 17 months. 

The following table presents the changes in our environmental accrual, which was primarily included in Long-term liabilities (in millions of

At December 31, 2022, our environmental accrual of $17.7 million represented our estimate of the incremental remediation cost based on: (i) 

proposed alternatives in the final feasibility study related to the Trentwood facility; (ii) currently available facts with respect to our Newark facility; and 
(iii) facts related to certain other locations owned or formerly owned by us. In accordance with approved and proposed remediation action plans, we expect 
that the implementation and ongoing monitoring could occur over a period of 30 or more years.

As additional facts are developed, feasibility studies are completed, remediation plans are modified, necessary regulatory approvals for the 
implementation of remediation are obtained, alternative technologies are developed and/or other factors change, there may be revisions to management’s 
estimates and actual costs may exceed the current environmental accruals. We believe at this time that it is reasonably possible that undiscounted costs 
associated with these environmental matters may exceed current accruals by amounts that could be, in the aggregate, up to an estimated $11.6 million over 
the remediation period. It is reasonably possible that our recorded estimate will change in the next 12 months.

Other Contingencies. We are party to various lawsuits, claims, investigations and administrative proceedings that arise in connection with past and 
current operations. We evaluate such matters on a case-by-case basis and our policy is to vigorously contest any such claims we believe are without merit. 
We accrue for a legal liability when it is both probable that a liability has been incurred and the amount of the loss is reasonably estimable. Quarterly, in 
addition to when changes in facts and circumstances require it, we review and adjust these accruals to reflect the impacts of negotiations, settlements, 
rulings, advice of legal counsel and other information and events pertaining to a particular case. While uncertainties are inherent in the final outcome of 
such matters and it is presently impossible to determine the actual cost that may ultimately be incurred, we believe that we have sufficiently accrued for 
such matters and that the ultimate resolution of pending matters will not have a material impact on our consolidated financial position, operating results or 
liquidity.

Amounts amortized out of AOCI related to pension and other postretirement benefits were included within Net periodic postretirement benefit cost 
(see Note 5).
Income tax amounts reclassified out of AOCI were included as a component of Income tax benefit (provision).
Amounts reclassified out of AOCI relating to sales of available for sale securities were included as a component of Other income (expense), net. We

As of December 31, 2022, we estimate a net mark-to-market loss before tax of $1.7 million in AOCI will be reclassified into Net (loss) income upon 
settlement within the next 12 months.

12. Restructuring

2022 Restructuring Plan. During 2022, we relocated our corporate headquarters from Foothill Ranch, California (“Foothill Ranch”) to Franklin, 

Tennessee (“Franklin”). In conjunction with the relocation, we initiated a restructuring plan during the quarter ended December 31, 2022, which consisted 
primarily of employee retention benefits aimed at incentivizing Foothill Ranch employees to assist with the buildout of the new corporate function in 
Franklin (“2022 Restructuring Plan”). At December 31, 2022, the total amount expected to be incurred in connection with the 2022 Restructuring Plan was 
$4.5 million. During the year ended December 31, 2022, we incurred restructuring costs of $2.2 million related to the 2022 Restructuring Plan, which 
consisted of employee-related costs and office rent within Restructuring costs (benefit) in our Statements of Consolidated (Loss) Income. We intend to be 
fully completed with the 2022 Restructuring Plan by December 31, 2023.

2020 Restructuring Plan. We initiated a restructuring plan during the quarter ended June 30, 2020, which consisted primarily of reduction in force 

measures (“2020 Restructuring Plan”) in order to align our projected operational requirements with reduced short and mid-term commercial aerospace 
demand as a result of the Coronavirus Disease 2019 (“COVID-19”) pandemic. We incurred total restructuring costs of $6.7 million related to the 2020 
Restructuring Plan, which consisted of severance, voluntary buyout packages, outplacement services, estimated medical costs and associated payroll costs 
within Restructuring costs (benefit) in our Statements of Consolidated (Loss) Income. We completed the 2020 Restructuring Plan as of December 31, 2021.

In 2021, we revised our production forecasts, thereby reducing the estimated number of headcount reductions necessary under the 2020 
Restructuring Plan as compared with our initial requirements. These reductions to accommodate the revised headcount requirements are included in 
Other adjustments with an offset to Restructuring costs (benefit) in our Statements of Consolidated (Loss) Income.

The state income tax benefit was $1.1 million in 2022, reflecting an increase of $1.5 million due to state net operating loss (“NOL”) carryforward 
expirations and tax rate true-ups in various states and a $0.1 million increase in the valuation allowance relating to certain state net operating losses. 
The state income tax benefit was $0.7 million in 2021, reflecting an increase of $1.3 million due to state NOL carryforward expirations and tax rate 
true-ups in various states, offset by a $1.6 million decrease in the valuation allowance relating to certain state net operating losses. State income 
taxes were $1.3 million in 2020, reflecting an increase of $3.7 million due to state NOL carryforward expirations and tax rate true-ups in various 
states, partially offset by a $3.5 million decrease in the valuation allowance relating to certain state net operating losses.

Deferred Income Taxes. Deferred income taxes reflect the net tax effects of temporary differences between the carrying amounts of assets and 

liabilities for financial reporting purposes and amounts used for income tax purposes. The following table presents the components of our net deferred 
income tax assets and liabilities (in millions of dollars):

Deferred income tax assets:

Tax Attributes. At December 31, 2022, we had $160.7 million of NOL carryforwards available to reduce future cash payments for federal income 
taxes in the United States. H.R.1, commonly referred to as the Tax Cut and Jobs Act, allows NOLs generated prior to December 31, 2017 (including our 
NOL carryforwards) to be fully deducted against 100% of taxable income until fully utilized or expired. NOL carryforwards generated after December 31, 
2017 do not expire and can be carried forward indefinitely. For losses arising in taxable years beginning after December 31, 2017, the net operating loss 
deduction for taxable years beginning after December 31, 2020, is limited to 80% of the excess (if any) of taxable income. Our State NOL carryforwards 
expire periodically through 2030.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

In addition, we had $12.0 million of federal research and development (“R&D”) credit carryforwards to offset regular federal income tax 

requirements. Our R&D credit carryforwards expire periodically through 2042.

In assessing the realizability of deferred tax assets, management considers whether it is “more likely than not” that some portion or all of the 
deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the 
periods in which those temporary differences become deductible. Management considers taxable income in carryback years, the scheduled reversal of 
deferred tax liabilities, tax planning strategies and projected future taxable income in making this assessment. Due to uncertainties surrounding the 
realization of some of our deferred tax assets, primarily including state NOL carryforwards sustained during the prior years and expiring tax benefits, we 
have a valuation allowance against certain deferred tax assets. When recognized, the tax benefits relating to any reversal of this valuation allowance will be 
recorded as a reduction of income tax expense. There was a decrease in the valuation allowance of $0.9 million in 2022, a decrease in the valuation 
allowance of $1.8 million in 2021 and a decrease in the valuation allowance of $3.5 million in 2020.

The decrease in the valuation allowance for 2022 was primarily due to the liquidation of an inactive passive insurance company, and its related 
separate return limitation year (“SRLY”) net operating losses. The decrease in the valuation allowance for 2021 was primarily due to the expiration of state 
NOL carryforwards and the related reversal of their valuation allowances. The decrease in the valuation allowance for 2020 was primarily due to the 
expiration of state NOL carryforwards and the related reversal of their valuation allowances.

Other. We and our subsidiaries file income tax returns in the U.S. federal jurisdiction and various states and foreign jurisdictions.

Our tax returns for certain past years are still subject to examination by taxing authorities and the use of NOL carryforwards in future periods could 

trigger a review of attributes and other tax matters in years that are not otherwise subject to examination.

We have gross unrecognized benefits relating to uncertain tax positions. The following table presents a reconciliation of changes in the gross 

unrecognized tax benefits (in millions of dollars):

Gross unrecognized tax benefits at beginning of period
Gross increases for tax positions of current year
Gross increases for tax positions of prior years
Gross decreases for tax positions of prior years

If and when the $5.0 million of gross unrecognized tax benefits at December 31, 2022 are recognized, $5.0 million will be reflected in our income 

tax provision and thus affect the effective tax rate in future periods.

In addition, we recognize interest and penalties related to unrecognized tax benefits in the income tax provision. We had $0.1 million and $0.2 
million accrued for interest and penalties at December 31, 2022 and December 31, 2021, respectively. Of these amounts, none were considered current and, 
as such, were included in Long-term liabilities on our Consolidated Balance Sheets as of December 31, 2022 and December 31, 2021. We recognized 
interest and penalties of $0.3 million in our tax provision in 2020.

We do not expect our gross unrecognized tax benefits to significantly change within the next 12 months.

15. Net (Loss) Income Per Share

Basic net (loss) income per share is computed by dividing distributed and undistributed net (loss) income allocable to common shares by the 
weighted-average number of common shares outstanding during the applicable period. The basic weighted-average number of common shares outstanding 
during the period excludes non-vested share-based payment awards. Diluted net (loss) income per share was calculated under the treasury stock method for 
2022, 2021 and 2020, which in all years was more dilutive than the two‑class method.

The following table sets forth the computation of basic and diluted net (loss) income per share (in millions of dollars, except share and per share 

amounts):

Quantities in the following discussion are denoted in whole shares. For the years ended December 31, 2022 and December 31, 2021, approximately 
139,000 and 213,000 potentially dilutive shares, respectively, were excluded from the computation of net loss per share as their effect would have 
been anti‑dilutive. A total of 44,000 non-vested RSAs, RSUs and performance shares for the year ended December 31, 2020 were excluded from the 
weighted-average diluted shares computation as their inclusion would have been anti-dilutive.

Item 9A. Controls and Procedures

Evaluation of Disclosure Controls and Procedures. We maintain disclosure controls and procedures that are designed to ensure that information 

required to be disclosed in our reports under the Securities Exchange Act of 1934 is processed, recorded, summarized and reported within the time periods 
specified in the SEC’s rules and forms and that such information is accumulated and communicated to management, including the principal executive 
officer and principal financial officer, to allow for timely decisions regarding required disclosure. In designing and evaluating the disclosure controls and 
procedures, management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of 
achieving the desired control objectives and management is required to apply its judgment in evaluating the cost-benefit relationship of possible controls 
and procedures. An evaluation of the effectiveness of the design and operation of our disclosure controls and procedures was performed as of the end of the 
period covered by this Report under the supervision of and with the participation of our management, including the principal executive officer and principal 
financial officer. Based on that evaluation, our principal executive officer and principal financial officer concluded that our disclosure controls and 
procedures were effective as of December 31, 2022 at the reasonable assurance level.

Management’s Annual Report on Internal Control Over Financial Reporting. Our management is responsible for establishing and maintaining 

adequate internal control over financial reporting as defined in Rule 13a-15(f) under the Securities Exchange Act of 1934. Our internal control over 
financial reporting is designed under the supervision of our principal executive officer and principal financial officer and effected by our Board of 
Directors, management and other personnel, to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial 
statements for external purposes in accordance with accounting principles generally accepted in the United States and include those policies and procedures 
that:

(1)

(2)

(3)

Pertain to the maintenance of records that in reasonable detail accurately and fairly reflect our transactions and the dispositions of our assets;

Provide reasonable assurance that our transactions are recorded as necessary to permit preparation of financial statements in accordance with 
accounting principles generally accepted in the United States and that our receipts and expenditures are being made only in accordance with 
authorizations of our management and Board of Directors; and

Provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of our assets that could 
have a material effect on our financial statements.

Because of inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Therefore, even those systems 

determined to be effective can provide only reasonable assurance with respect to financial statement preparation and presentation.

Under the supervision and with the participation of our management, including our principal executive officer and principal financial officer, we 

assessed the effectiveness of our internal control over financial reporting as of December 31, 2022, using the criteria set forth by the Committee of 
Sponsoring Organizations of the Treadway Commission in Internal Control – Integrated Framework as established in 2013. Based on that evaluation, our 
principal executive officer and principal financial officer concluded that our internal control over financial reporting was effective as of December 31, 
2022.

Deloitte & Touche LLP, the independent registered public accounting firm that audited our consolidated financial statements for the year ended 
December 31, 2022 included in Item 8. “Financial Statements and Supplementary Data” of this Report, has issued an attestation report on the effectiveness 
of our internal control over financial reporting.

Changes in Internal Control Over Financial Reporting. We had no changes in our internal control over financial reporting during our most recently 

completed fiscal quarter that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Supplier Financing Transaction (provided, that the foregoing exclusion of this clause (ii) shall in no way be construed to apply to 
any right, title or interest in any proceeds of the sale of such Accounts or amounts otherwise paid or payable to or claims arising in 
favor of any Grantor pursuant to or in connection with any such Permitted Supplier Financing Transaction) or (iii) any United States 
intent-to-use trademark applications to the extent that, and solely during the period in which, the grant of a security interest therein

upon submission and acceptance by the PTO of an amendment to allege use pursuant to 15 U.S.C. Section 1060(a) (or 

129288890_13

5

 
 
any successor provision), such intent-to-use trademark application shall be considered Collateral.”
