BUSINESS

OVERVIEW

Owens  Corning  is  a  global  building  and  construction  materials  leader  committed  to  building  a  sustainable  future  through  material  innovation.  Its  roofing
products and systems enhance curb appeal of people’s homes and protect residential and commercial buildings. Its insulation products conserve energy and
improve acoustics, fire resistance and air quality in the spaces where people live, work and play. Its fiberglass composites make thousands of products lighter,
stronger and more durable.

The  business  is  global  in  scope,  with  operations  in  30  countries,  and  human  in  scale,  with  approximately  18,000  employees  and  longstanding,  local
relationships with its customers. Founded in 1938 and based in Toledo, Ohio, Owens Corning recorded net sales in 2023 of $9.7 billion.

Unless the context indicates otherwise, the terms “Owens Corning,” “Company,” “we” and “our” in this report refer to Owens Corning and its subsidiaries.
References to a particular year mean the Company’s year commencing on January 1 and ending on December 31 of that year.

SEGMENT OVERVIEW

The Company has an integrated business model with three reportable segments: Roofing, Insulation and Composites. Our Roofing, Insulation and Composites
reportable segments accounted for approximately 40%, 37% and 23% of our total reportable segment net sales, respectively, in 2023.

Roofing

Our primary products in the Roofing segment are laminate and strip asphalt roofing shingles. Other products include roofing components and oxidized asphalt.
We have been able to meet the growing demand for longer lasting, aesthetically attractive laminate products with modest capital investment. 

We sell shingles and roofing components primarily through distributors, home centers and lumberyards in the United States. Oxidized asphalt is a significant
input used in the production of our asphalt roofing shingles. We are vertically integrated and have manufacturing facilities that process asphalt for use in our
roofing shingles manufacturing process. In addition, we sell processed asphalt to other shingle manufacturers, to roofing contractors for built-up roofing asphalt
systems  and  to  manufacturers  in  a  variety  of  other  industries,  including  automotive,  chemical,  rubber  and  construction. Asphalt  input  costs  and  third-party
asphalt sales prices are correlated to crude oil prices.

Demand  for  products  in  our  Roofing  segment  is  generally  driven  by  both  residential  repair  and  remodeling  activity  and  by  new  residential  construction.
Roofing damage from major storms can significantly increase demand in this segment. As a result, sales in this segment do not always follow seasonal home
improvement, remodeling and new construction industry patterns as closely as our Insulation segment.

Our  Roofing  segment  competes  primarily  with  asphalt  shingle  manufacturers  in  the  United  States.  According  to  various  industry  reports  and  Company
estimates, Owens Corning’s Roofing segment is the second largest producer of asphalt roofing shingles in the United States. Principal methods of competition
include innovation and product design, proximity to customers, quality and price.

Our manufacturing operations are generally continuous in nature, and we warehouse much of our production prior to sale since we operate with relatively short
delivery cycles. One of the raw materials important to this segment is sourced from a sole supplier. We have a long-term supply contract for this material and
have no reason to believe that any availability issues will exist. If this supply was to become unavailable, our production could be interrupted until such time as
the  supplies  again  became  available  or  the  Company  reformulated  its  products. Additionally,  the  supply  of  asphalt,  another  significant  raw  material  in  this
segment, has been constricted at times. Although this has not caused a significant interruption of our production in the past, prolonged asphalt shortages would
restrict our ability to produce products in this segment.

Insulation

Our insulating products provide a variety of benefits such as energy conservation, thermal functionality, improved acoustical performance and convenience of
installation and use. Our Insulation segment includes a diverse portfolio of high, mid and low-temperature products with a geographic mix of United States,
Canada, Europe, Asia-Pacific and Latin America, a market mix of residential, commercial, industrial and other markets, and a channel mix of retail, contractor
and distribution.

Our products in the North American residential market include thermal and acoustical batts, loosefill insulation, spray foam, foam sheathing and accessories,
and are sold under well-recognized brand names and trademarks, such as Owens Corning PINK  Next Gen™ FIBERGLAS™ Insulation. Our products in the
commercial  and  industrial  markets  include  glass  fiber  pipe  insulation,  energy  efficient  flexible  duct  media,  bonded  and  granulated  stone  wool  insulation,
cellular glass insulation and foam insulation used in above- and below-grade construction applications, and are sold under well-recognized brand names and
trademarks, such as FOAMULAR , FOAMGLAS  and Paroc . We sell our insulation products primarily to insulation installers, home centers, lumberyards,
retailers and distributors in the United States, Canada, Europe, Asia-Pacific and Latin America.

®

®

®

Demand for Owens Corning’s insulating products is driven by North American new residential construction, repair and remodeling activity, commercial and
industrial construction activity in the United States, Canada, Europe, Asia-Pacific and Latin America, and increasingly stringent building codes and the growing
need for energy efficiency. Demand in the segment typically follows seasonal home improvement, remodeling and renovation and residential, commercial and
industrial construction industry patterns. Demand for residential insulation in North America typically follows housing starts on a three-month lagged basis,
although  the  new  residential  construction  cycle  can  elongate  due  to  labor  availability  and  other  factors  beyond  our  control.  The  peak  season  for  home
construction  and  remodeling  in  our  geographic  markets  generally  corresponds  with  the  second  and  third  calendar  quarters.  Demand  for  commercial  and
industrial applications is more heavily tied to industrial production growth, commercial construction activity, and overall economic conditions in the global
markets we serve.

Our Insulation segment competes primarily with fiberglass insulation manufacturers in the United States, with an international presence in Canada, Europe,
Asia-Pacific  and  Latin America. According  to  industry  reports  and  Company  estimates,  Owens  Corning  is  North America’s  largest  producer  of  residential,
commercial  and  industrial  insulation.  Principal  methods  of  competition  include  innovation  and  product  design,  service,  location,  quality,  price  and
compatibility of systems solutions.

Composites

Owens Corning glass fiber materials can be found in over 40,000 end-use applications primarily within three markets: building and construction, renewable
energy and infrastructure. Such end-use applications include building structures, roofing shingles, tubs and showers, pools, decking, flooring, pipes and tanks,
poles, electrical equipment and wind-energy turbine blades. Our products are manufactured and sold worldwide. We primarily sell our products directly to parts
molders and fabricators. Within the building and construction market, our Composites segment sells glass fiber and/or glass mat directly to a small number of
major shingle manufacturers, including our own Roofing segment.

Our Composites segment includes vertically integrated material solutions. The Company manufactures, fabricates and sells glass reinforcements in the form of
fiber. Glass reinforcement materials are also used downstream by the Composites segment to manufacture and sell glass fiber products in the form of non-
wovens, fabrics and composite lumber.

Demand for composites is driven by general global economic activity and, more specifically, by the increasing replacement of traditional materials, such as
aluminum, wood, paper and steel with composites that offer lighter weight, improved strength, lack of conductivity and corrosion resistance.

We compete with glass fiber and building material manufacturers worldwide. According to various industry reports and Company estimates, our Composites
segment  is  a  world  leader  in  the  production  of  glass  fiber  reinforcement  and  other  building  materials.  Primary  methods  of  competition  include  innovation,
quality, customer service, global geographic reach, sustainability and product customization.

GENERAL

Intellectual Property

The Company relies on a combination of intellectual property laws, as well as confidentiality procedures and contractual provisions, to protect our intellectual
property, proprietary technology and our brands. Through continuous and extensive use of the color PINK  since 1956, Owens Corning became the first owner
of a single color trademark registration. In addition to our Owens Corning and PINK  brands, the Company has registered, and applied for the registration of,
U.S.  and  international  trademarks,  service  marks,  and  domain  names. Additionally,  the  Company  owns  numerous  U.S.  and  international  patents  and  patent
applications,  covering  certain  of  our  proprietary  technology  resulting  from  research  and  development  efforts.  Over  time,  the  Company  has  assembled  a
portfolio  of  intellectual  property  rights  including  patents,  trademarks,  service  marks,  copyrights,  domain  names,  know-how  and  trade  secrets  covering  our
products,  services  and  manufacturing  processes.  Our  proprietary  technology  is  not  dependent  on  any  single  or  group  of  intellectual  property  rights  and  the
Company does not expect the expiration of existing intellectual property to have a material adverse effect on the business as a whole. The Company believes
the duration of our patents is adequate relative to the expected lives of our products. Although the Company protects its intellectual property and proprietary
technology, any significant impairment of, or third-party claim against, our intellectual property rights could harm our business or our ability to compete.

Environmental Control

Owens Corning has established policies and procedures to ensure that its operations are conducted in compliance with all relevant laws and regulations and that
enable  the  Company  to  meet  its  high  standards  for  corporate  sustainability  and  environmental  stewardship.  Our  manufacturing  facilities  are  subject  to
numerous foreign, federal, state and local laws and regulations relating to the presence of hazardous materials, pollution and protection of the environment,
including emissions to air, reductions of greenhouse gases, discharges to water, management of hazardous materials, handling and disposal of solid wastes, use
of chemicals in our manufacturing processes, and remediation of contaminated sites. All Company manufacturing facilities are either ISO 14001 certified or
deploy  environmental  management  systems  based  on  ISO  14001  principles. The  Company’s  2030  Sustainability  Goals  include  targets  related  to  significant
global  reductions  in  energy  use,  water  consumption,  waste  to  landfill,  and  emissions  of  greenhouse  gases,  fine  particulate  matter,  and  volatile  organic  air
emissions, and protection of biodiversity. The Company is dedicated to continuous improvement in its environmental, health and safety performance and to
achieving its 2030 Sustainability Goals.

The  Company  has  not  experienced  a  material  adverse  effect  upon  its  capital  expenditures  or  competitive  position  as  a  result  of  environmental  control
legislation and regulations. Operating costs associated with environmental compliance were approximately $49 million in 2023. The Company continues to
invest in equipment and process modifications to remain in compliance with applicable environmental laws and regulations worldwide.

Our manufacturing facilities are subject to numerous national, state and local environmental protection laws and regulations. Regulatory activities of particular
importance  to  our  operations  include  those  addressing  air  pollution,  water  pollution,  waste  disposal  and  chemical  control.  It  is  possible  that  new  laws  and
regulations will specifically address climate change, volatile organic compounds, ozone forming emissions and fine particulate matter. New environmental and
chemical regulations could impact our ability to expand production or construct new facilities in geographic regions in which we operate. However, based on
information known to the Company, including the nature of our manufacturing operations and associated air emissions, at this time we do not expect any of
these new laws, regulations or activities to have a material adverse effect on our results of current operations, financial condition or long-term liquidity.

Owens  Corning  is  involved  in  remedial  response  activities  and  is  responsible  for  environmental  remediation  at  a  number  of  sites,  including  certain  of  its
currently  owned  or  formerly  owned  plants.  These  responsibilities  arise  under  a  number  of  laws,  including,  but  not  limited  to,  the  Federal  Resource
Conservation  and  Recovery Act,  and  similar  state  or  local  laws  pertaining  to  the  management  and  remediation  of  hazardous  materials  and  petroleum.  The
Company has also been named a potentially responsible party under the United States Federal Superfund law, or state equivalents, at a number of disposal sites.
The Company became involved in these sites as a result of government action or in connection with business acquisitions. At the end of 2023, the Company
was involved with a total of 22 sites worldwide, including 10 Superfund and state or country equivalent sites and 12 owned or formerly owned sites. None of
the liabilities for these sites are individually significant to the Company.

ITEM 1.

BUSINESS (continued)

Remediation activities generally involve a potential range of activities and costs related to soil, groundwater and sediment contamination. This can include pre-
cleanup activities such as fact finding and investigation, risk assessment, feasibility studies, remedial action design and implementation (where actions may
range from monitoring to removal of contaminants, to installation of longer-term remediation systems). A number of factors affect the cost of environmental
remediation, including the number of parties involved in a particular site, the determination of the extent of contamination, the length of time the remediation
may require, the complexity of environmental regulations, variability in clean-up standards, the need for legal action, and changes in remediation technology.
Taking these factors into account, Owens Corning estimates the costs of remediation to be paid over a period of years. The Company accrues an amount on an
undiscounted basis, when a liability is probable and reasonably estimable. Actual cost may differ from these estimates for the reasons mentioned above.

At December 31, 2023, the Company had an accrual totaling $4 million for its environmental liabilities, of which the current portion is $1 million. Changes in
required remediation procedures or timing of those procedures at existing legacy sites, or discovery of contamination at additional sites, could result in material
increases to the Company’s environmental obligations.

Additional Government Laws and Regulations

In addition to environmental laws and regulations, we are subject to various laws and regulations around the world. For example, trade regulations, including
tariffs or other import or export restrictions, may increase the cost of some of our raw materials or cross-border shipments, and limit our ability to do business
in certain countries or with certain individuals. Our business is also subject to competition laws in the various jurisdictions where we operate, including the
Sherman  Antitrust  Act  and  related  federal  and  state  antitrust  laws  in  the  United  States,  as  well  as  similar  foreign  laws  and  regulations.  These  laws  and
regulations generally prohibit competitors from fixing prices, boycotting competitors, or engaging in other conduct that unreasonably restrains competition, and
such laws and regulations may impact potential business relationships or transactions with third parties in the future. In addition, health and safety regulations
have necessitated, and may continue to necessitate, increased operating costs or capital investments to promote a safe working environment. The Company is
also required to comply with increasingly complex and changing laws and regulations enacted to protect business and personal data in the United States and
other jurisdictions regarding privacy, data protection and data security, including those related to the collection, storage, use, transmission and protection of
personal information and other consumer, customer, vendor or employee data. Further, an increasing number of laws and regulations focused on product and
chemical hazards, including regulations concerning the impact of product manufacturing and use on climate change, and resulting preferential product selection
could also impact our ability to manufacture and sell certain products or require significant research and development investment and capital expenditures to
meet  regulatory  requirements.  With  respect  to  the  laws  and  regulations  noted  above,  as  well  as  other  applicable  laws  and  regulations,  the  Company’s
compliance  programs,  may  under  certain  circumstances,  involve  material  investments  in  the  form  of  additional  processes,  training,  personnel,  information
technology and capital. For a discussion of the risks associated with certain applicable laws and regulations, see Item 1A, “Risk Factors.”

Sustainability

As a worldwide leader in our industry, our goal is to be at the forefront of corporate sustainability efforts. It is our ambition to be a net-positive company, that
is, one whose positive impact of our people and products, is greater than the negative impact of manufacturing our products. We work to continually increase
the good our people and products do while we concurrently strive to reduce the negative environmental impact of our operations.

Our climate-related sustainability efforts have led Owens Corning to develop a range of strategies and tactics that have had a significant impact on the way we
conduct our business. We strive to reduce the greenhouse gas emissions released throughout the entire life cycle of our products by improving the use-phase
impacts of our products, making our manufacturing processes more energy-efficient, sourcing more renewable electricity, improving our supply chain logistics,
increasing recycled content, and developing end-of-life recycling solutions. Together, this work helps to reduce the environmental impact of our operations and
lowers the embodied carbon in our products – an attribute of growing importance to our customers.

Many  of  Owens  Corning’s  products  are  made  using  heavy,  industrialized  manufacturing  processes. While  we  strive  to  continue  our  progress  to  reduce  our
impact, our factories produce various emissions, including greenhouse gases. Owens Corning is subject to or has chosen to voluntarily participate in Emissions
Trading Schemes around the world. Broad and gradual tightening of national, regional, and state government limits on emissions could disrupt our access to
energy sources or specific raw materials, which in turn could disrupt the manufacturing of products dependent upon them. Owens Corning invests in research
and development on climate-related risks and opportunities.

Human Capital Resources

The Company’s long-term success is dependent upon its access to and development of management and primary employees who are sufficiently skilled and
capable of the work necessary to achieve the Company’s short-and long-term business objectives. To maintain employee engagement, Owens Corning strives
to ensure its people feel valued, included, and engaged – from recruitment to retirement. That is why Owens Corning is dedicated to fostering an environment
of learning and growth within a supportive, caring culture. We are committed to providing a safe, healthy workplace and a meaningful, engaging employee
experience.

As  of  December  31,  2023,  Owens  Corning  had  approximately  18,000  employees,  of  which  approximately  9,000  were  located  outside  the  United  States.
Approximately 8,200 (46%) of hourly employees are subject to collective bargaining agreements. The Company regularly engages its salaried, non-represented
and  represented  primary  employees  to  collect  feedback  and  based  on  that  feedback  believes  employee  engagement  and  relations  are  good.  In  2023,  the
Company also engaged in an Employee Value Proposition survey and considered employee feedback in formulating its value proposition, including changes to
compensation  and  benefits  offerings  such  as  sick  leave  enhancements  for  primary  employees  and  improvements  to  our  facilities,  including  the  roll-out  of
personal dignity spaces.

Safety and Well-Being

One  of  our  primary  objectives  is  the  safety  and  well-being  of  our  employees. Working  safely  is  an  unconditional,  organization-wide  expectation  at  Owens
Corning,  which  we  believe  directly  benefits  employees’  lives,  improves  our  manufacturing  processes  and  reduces  our  costs.  The  Company  maintains
comprehensive safety programs focused on identifying hazards and eliminating risks that can lead to severe injuries. In the fall of 2023, the Company kicked
off its employee-developed “Safer Together” initiative, intended to increase employee focus and collective engagement on safety. One of our primary safety
measures is the Recordable Incident Rate (“RIR”) as defined by the United States Bureau of Labor Statistics. For the year ended December 31, 2023, our RIR
was 0.60, compared to 0.65 as reported in the same period for the prior year.

Additionally, with our Healthy Living platform, we provide a multifaceted well-being program designed to drive sustainable, long-term change, improve the
health and lives of employees, and strengthen the culture and work experience.

Employee Performance and Related Objectives

We also focus on evaluating and managing employee performance, development, succession planning, and turnover. Our goal is to create a high-performance
culture and teams that are diverse, capable and engaged. We strive to have clear objectives, effective performance management, and a structure that includes
regular feedback, talent reviews, succession planning, development, and compensation analysis.

Corporate Culture

Another  objective  we  pursue  is  maintaining  a  corporate  culture  focused  on  inclusion  and  diversity,  ethics  and  compliance,  training  and  positive  employee
relations and engagement. The Company believes its success and sustainability are enhanced by an inclusive and diverse workforce. We believe that inclusion
and  diversity  add  value  to  the  business  by  fostering  an  environment  that  leads  to  high  engagement  and  innovative  thinking  in  the  workplace.  Five  years
following  the  Company's  pledge  to  diversity  &  inclusion,  there  is  more  work  to  be  done,  and  the  Company  continues  to  pursue  diversity  in  its  workforce
through diverse candidate slates, diversity on hiring committees, and development programs, and the continued focus on development of management skills
needed  to  sustain  progress  in  this  area  through  the  roll-out  of  inclusive  leadership  training  across  the  organization.  Owens  Corning  operates  programs  that
foster gender and ethnic diversity as well as equality within its workforce, including supporting various employee-led affinity groups, so its employees feel
valued and appreciated for the distinct voices they bring to the team.

As of December 31, 2023, the composition of our Board of Directors was 60% demographically diverse, which includes gender, race, ethnicity, nationality,
national origin or other elements of one’s identity. Leadership positions were comprised of approximately 29% women globally and 18% people of color in the
United States. Our 2030 diversity goals set targets for our leadership positions of 35% women globally and 22% people of color in the United States.

The  Company  has  a  robust  pay  equity  system,  which  includes  multiple  processes  and  controls  to  prevent  pay  equity  gaps  from  occurring.  We  perform  a
biennial  pay  equity  review  with  the  assistance  of  a  third-party  vendor  who  utilizes  a  strong,  statistical  analysis  of  pay  equity  across  our  global  salaried
workforce. We promptly remediate all identified and substantiated pay gaps through pay increases.

Ethics and compliance efforts include our support of the Owens Corning Code of Conduct (“Code of Conduct”), which is dedicated to encouraging compliance
with a range of legal guidelines and our corporate values. Our training efforts encompass the Code of Conduct and other areas of compliance and development
as relevant to employees. We also seek to foster positive and productive relations with the labor organizations representing them.

Owens  Corning  employees  contribute  service  hours  to  boards,  special  causes  and  nonprofit  organizations  in  the  communities  where  they  live  and  operate.
These programs aim to enable the Company’s employees to connect with the community, further improve its reputation locally and globally, and instill a sense
of pride in the workforce.

Owens Corning is a recognized leader on advancing social issues, including issues related to diversity, equity and inclusion and human rights. Select awards
and honors earned by the Company include:

•

In  an  enterprise  as  diverse  as  ours,  a  wide  range  of  factors  could  affect  future  performance.  We  discuss  in  this  section  some  of  the  risk  factors  that  could
materially and adversely affect our business, financial condition, value and results of operations. You should not interpret the disclosure of any risk factor to
imply that the risk has not already materialized. You should consider these risk factors in connection with evaluating the forward-looking statements contained
in this Annual Report on Form 10-K because these risk factors could cause our actual results and financial condition to differ materially from those projected in
forward-looking statements.

The Company maintains processes that aim to manage enterprise risks through identification and mitigation of those risks. Despite our efforts, we may fail to
identify or mitigate certain risks, which could have a material and adverse impact on our business, financial condition, value and results of operations in future
periods.

MACROECONOMIC, MARKET AND OPERATIONAL RISKS

Low levels of residential, commercial or industrial construction activity can have a material adverse impact on our business and results of operations.

A  large  portion  of  our  products  are  used  in  the  markets  for  residential  and  commercial  construction  and  repair  and  remodeling.  Demand  for  certain  of  our
products is affected in part by the level of new residential construction in the United States and elsewhere, although typically not until a number of months after
the  change  in  the  level  of  construction.  Lower  demand  in  the  regions  and  markets  where  our  products  are  sold  could  result  in  lower  revenues  and  lower
profitability. Historically, construction activity has been cyclical and is influenced by prevailing economic conditions, including the level of interest rates and
availability of financing, inflation, employment levels, consumer spending habits, consumer confidence and other macroeconomic factors outside our control.
Interest rates increased substantially in fiscal years 2022 and 2023, and may continue to increase. The combination of high interest rates and high levels of
inflation have reduced the affordability of mortgages and other financing options, and increased the cost of home improvement projects. These trends have
likely  resulted  in  reduced  levels  of  repair  and  remodel  as  well  as  new  construction  activity  and  demand  for  our  products,  and  we  expect  these  trends  may
continue for the foreseeable future. We cannot predict if or when interest rates or inflation levels will stabilize or decline or the impact that any such decline
may have on repair and remodel activity, new construction activity, demand for our products, our business generally, or our financial condition.

Residential and commercial construction is also affected by the cost and availability of skilled labor, which could impact both the cost and pace of construction
activity, as well as the construction methods used, all of which could adversely affect demand for our products.

Some of our products, particularly in our Insulation business, are used in industrial applications, such as piping and storage tanks. Lower levels of industrial
production and other macroeconomic factors affecting industrial construction activity could lessen demand for those products and lead to lower revenues or
profitability.

We may be exposed to cost increases or reduced availability of raw materials or transportation, which could reduce our margins and have a material
adverse impact on our business, financial condition and results of operations.

Our business relies heavily on certain commodities and raw materials used in our manufacturing processes. Additionally, we spend a significant amount on
inputs that are influenced by energy prices, such as asphalt, chemicals, resins, and transportation. Price increases for these inputs could raise costs and reduce
our margins if we are not able to offset them by increasing the prices of our products, improving productivity or hedging, where appropriate.

Availability of certain of the raw materials we use has occasionally been limited, and our sourcing of some of these raw materials from a limited number of
suppliers, and in some cases a sole supplier, increases the risk of unavailability. For example, if one of the raw materials important to our business is sourced
from  a  sole  supplier,  our  production  could  be  interrupted  regardless  of  whether  we  have  a  long-term  supply  contract  for  the  material.  Global  economic
conditions may also result in global or regional supply chain issues that adversely impact our access to raw materials and supplies. Despite our contractual
supply agreements with many of our suppliers, and despite any programs we may undertake to mitigate supply risks, it is possible that we could experience a
lack of certain raw materials that limits our ability to manufacture our products, thereby materially and adversely impacting our business, financial condition
and results of operations.

In  addition,  we  are  dependent  on  third-party  freight  carriers  to  transport  some  of  our  raw  materials  and  products.  We  may  be  unable  to  transport  our  raw
materials  or  products  in  a  timely  manner  or  at  economically  favorable  rates  in  certain  circumstances,  particularly  in  cases  of  adverse  market  conditions  or
disruptions to transportation infrastructure.

Supply constraints and increases in the cost of energy could have a material adverse impact on our business or results of operations.

The cost of producing our products is sensitive to the price of energy, including its impact on transport costs which is subject to factors outside of our control.
Energy prices, in particular oil and natural gas, have fluctuated in recent years. For example, natural gas forms the primary energy source for our European
operations and our European operations can be directly affected by volatility in the cost and availability of natural gas. Natural gas supply shortages could lead
to additional price increases, energy supply rationing, or temporary reduction in our European operations, which could have a material adverse impact on our
business or results of operations.

We are subject to risks and uncertainties associated with our international operations.

We sell products and operate plants throughout the world. Our international sales and operations are subject to risks and uncertainties, including:

•

•

•

•

•

•

•

•

•

•

difficulties and costs associated with complying with a wide variety of complex and changing laws, including securities laws, climate-related laws, tax
laws,  employment  and  pension-related  laws,  competition  laws,  U.S.  and  foreign  export  and  trading  laws,  and  laws  governing  improper  business
practices, treaties and regulations;

limitations on our ability to enforce legal rights and remedies;

adverse domestic or international economic and political conditions, business interruption, war and civil disturbance;

changes to tax, currency, or other laws or policies that may adversely impact our ability to repatriate cash from non-United States subsidiaries, make
cross-border investments, or engage in other intercompany transactions;

future tax legislation, regulations, or related guidance or interpretations;

changes  to  tariffs  or  other  import  or  export  restrictions,  penalties  or  sanctions,  including  modification  or  elimination  of  international  agreements
covering trade or investment;

costs and availability of shipping and transportation;

nationalization or forced relocation of properties by foreign governments;

currency exchange rate fluctuations between the United States Dollar and foreign currencies; and

uncertainty with respect to any potential changes to laws, regulations and policies that could exacerbate the risks described above.

As  we  continue  to  expand  our  business  globally,  we  may  have  difficulty  anticipating  and  effectively  managing  these  and  other  risks  that  our  international
operations may face, which may adversely impact our business, financial condition and results of operations.

In  addition,  we  operate  in  many  parts  of  the  world  that  have  experienced  governmental  corruption  and  we  could  be  adversely  affected  by  violations  of  the
Foreign Corrupt Practices Act (“FCPA”) and similar worldwide anti-corruption laws. The FCPA and similar anti-corruption laws in other jurisdictions generally
prohibit  companies  and  their  intermediaries  from  making  improper  payments  to  officials  for  the  purpose  of  obtaining  or  retaining  business. Although  we
mandate compliance with these anti-corruption laws and maintain an anti-corruption compliance program, these measures may not prevent our employees or
agents  from  violating  these  laws.  If  we  were  found  liable  for  violations  of  anti-corruption  laws,  we  could  be  liable  for  criminal  or  civil  penalties  or  other
sanctions, which could have a material adverse impact on our business, financial condition and results of operations.

Our sales may fall rapidly in response to declines in demand because we do not operate under long-term volume agreements to supply our customers
and because of customer concentration in certain segments.

Many of our customer volume commitments are short-term; therefore, we do not have a significant manufacturing backlog. As a result, we do not benefit from
the visibility provided by long-term volume contracts against downturns in customer demand and sales. Further, we are not able to immediately adjust our costs
in response to declines in sales. Our ability to sell some of the products in our Insulation and Roofing segments is dependent on a limited number of customers,
who account for a significant portion of such sales. In 2023, we had one customer that represented 11% of our annual sales. The loss of key customers for these
products, a consolidation of key customers or a significant reduction in sales to those customers, could significantly reduce our revenues from these products.
In addition, if key customers experience financial pressure or

ITEM 1A.

RISK FACTORS (continued)

-9-

consolidate, they could attempt to demand more favorable contractual terms, which would place additional pressure on our margins and cash flows. Lower
demand  for  our  products,  loss  of  key  customers  and  material  changes  to  contractual  terms  could  materially  and  adversely  impact  our  business,  financial
condition and results of operations. Furthermore, some of our sales are concentrated in certain geographic areas, and market growth that is skewed to other
geographic areas may negatively impact our rate of growth or market share.

Worldwide economic conditions and credit tightening could have a material adverse impact on the Company.

The  Company’s  business  may  be  materially  and  adversely  impacted  by  changes  in  United  States  or  global  economic  conditions,  including  global  industrial
production rates, inflation, deflation, interest rates, availability of capital, consumer spending rates, energy availability and commodity prices, trade laws, and
the effects of governmental initiatives to manage economic conditions. Changes in and/or new laws, regulations and policies that may be enacted in the United
States  or  elsewhere  could  also  materially  impact  economic  conditions  and  the  Company's  business  and  results  of  operations. These  changes  and  conditions
could materially and adversely impact the Company’s operations, financial results and/or liquidity, including:

•

•

•
•
•

the financial stability of our customers or suppliers may be compromised, which could result in reduced demand for our products, additional bad debts
for the Company or non-performance by suppliers;

one or more of the financial institutions associated with our credit facilities could cease to fulfill their funding obligations, or the amount of eligible
receivables under our receivables securitization facility could decrease, which could materially and adversely impact our liquidity;

it may become more expensive or difficult to obtain financing or refinance the Company’s debt in the future;

the value of the Company’s assets held in pension plans may decline; and

the Company’s assets may be impaired or subject to write-down or write-off.

With the volatility in the current global economic climate, inflation and geopolitical events around the world, including the Russian invasion of Ukraine and the
Israel-Hamas conflict, it is difficult for us to predict the complete impact of the foregoing matters on our business and results of operations.

Uncertainty about global economic conditions may also cause consumers of our products to reduce or postpone spending in response to tighter credit, negative
financial  news  and/or  declines  in  income  or  asset  values.  This  could  have  a  material  adverse  impact  on  the  demand  for  our  products  and  on  our  financial
condition and operating results. A deterioration of economic conditions may exacerbate these adverse effects and could result in a wide-ranging and prolonged
impact on general business conditions, thereby negatively impacting our operations, financial results and/or liquidity.

We  are  subject  to  risks  relating  to  our  information  technology  systems  (including  cybersecurity)  risks,  and  any  failure  to  adequately  protect  our
critical information technology systems could materially affect our operations.

We  rely  on  information  technology  systems  across  our  operations,  including  for  management,  supply  chain  and  financial  information  and  various  other
processes and transactions. Our ability to effectively manage our business depends on the security, reliability and capacity of these systems. Our information
technology systems, some of which are dependent on services provided by third parties, may be vulnerable to damage, interruption, or shutdown due to any
number  of  causes  outside  of  our  control  such  as  catastrophic  events,  natural  disasters,  fires,  power  outages,  systems  failures,  telecommunications  failures,
employee  error  or  malfeasance,  security  breaches,  computer  viruses  or  other  malicious  codes,  ransomware,  unauthorized  access  attempts,  denial  of  service
attacks, phishing, hacking, and other cyberattacks. In addition, our operations in certain geographic locations may be particularly vulnerable to cybersecurity
attacks or other problems. Any such damage, interruption, or shutdown could cause delays or cancellation of customer orders or impede the manufacture or
shipment of products, processing of transactions or reporting of financial results. An attack or other problem with our systems could also result in the disclosure
of proprietary information about our business or confidential information concerning our customers or employees, which could result in significant damage to
our business and our reputation.

We  have  established  a  range  of  security  measures  that  are  designed  to  protect  against  the  unauthorized  access  to  and  misappropriation  of  our  information,
corruption  of  data,  intentional  or  unintentional  disclosure  of  confidential  information,  or  disruption  of  operations.  However,  advanced  cybersecurity  threats,
such as malware, ransomware, and phishing attacks, attempts to access information, and other security breaches, are persistent and continue to evolve, making
them increasingly difficult to identify and prevent. Protecting against these threats may require significant resources, and we may not be able to implement
measures that will protect against all of the significant risks to our information technology systems. In addition, we rely on a number of third-party service
providers to execute certain business processes and maintain certain information technology systems and infrastructure, and any breach of security on their part
could impair our ability to effectively operate.

ITEM 1A.

RISK FACTORS (continued)

-10-

Any  breach  of  our  security  measures,  or  those  of  our  third-party  service  providers,  could  result  in  unauthorized  access  to  and  misappropriation  of  our
information, corruption of data or disruption of operations or transactions, any of which could have a material adverse effect on our business strategy, results of
operations or financial condition.

Additionally, we regularly move data across national borders to conduct our operations and, consequently, are subject to a variety of laws and regulations in the
United  States  and  other  jurisdictions  regarding  privacy,  data  protection,  and  data  security,  including  those  related  to  the  collection,  storage,  handling,  use,
disclosure, transfer, and security of personal data, including the European Union General Data Protection Regulation. Our efforts to comply with privacy and
data protection laws may impose significant costs and challenges that are likely to increase over time.

Our  efforts  in  acquiring  and  integrating  other  businesses,  establishing  joint  ventures,  expanding  our  production  capacity  or  divesting  assets  are
subject to a number of risks.

Some  of  the  ways  we  have  historically  grown  or  restructured  our  business  have  been  through  acquisitions,  joint  ventures,  the  expansion  of  our  production
capacity and divestitures. Our ability to grow or restructure our business depends upon our ability to identify, negotiate and finance suitable arrangements. If
we cannot successfully execute on such arrangements or receive any required regulatory approvals on a timely basis, we may be unable to generate desired
returns, and our expectations of future results of operations, including cost savings and synergies, may not be achieved. Acquisitions, joint ventures, production
capacity expansions and divestitures involve substantial risks, including:

•
•
•
•
•
•
•
•
•
•

unforeseen difficulties in operations, technologies, products, services, accounting and personnel;

increased cybersecurity threats or incidents;

diversion of financial and management resources from existing operations;

unforeseen difficulties related to entering geographic regions, markets or product lines where we do not have prior experience;

risks relating to obtaining sufficient financing;

difficulty in integrating the acquired business’ standards, processes, procedures and controls with our existing operations;

potential loss of key employees;

unanticipated competitive responses;

potential loss of customers or suppliers; and

undisclosed or undiscovered liabilities or claims, or retention of unpredictable future liabilities.

Our  failure  to  address  these  risks  or  other  problems  encountered  in  connection  with  our  past  or  future  acquisitions,  including  the  planned  acquisition  of
Masonite, investments and divestitures could cause us to fail to realize the anticipated benefits of such transactions, incur unanticipated liabilities, and harm our
business  generally.  Future  acquisitions  and  investments  could  also  result  in  dilutive  issuances  of  our  equity  securities,  the  incurrence  of  debt,  contingent
liabilities,  or  amortization  expenses,  or  write-offs  of  goodwill,  any  of  which  could  have  a  material  adverse  impact  on  our  business,  financial  condition  and
results of operations. Also, the anticipated benefits of our investments may not materialize.

We  recently  announced  that  we  have  decided  to  review  strategic  alternatives  for  our  global  glass  reinforcements  business,  consistent  with  our  strategy  to
expand our building materials offering and focus on products and applications where we can build market-leading positions. While a range of options are under
consideration, including a potential sale, spin-off or other strategic option, there can be no assurance that the strategic review will result in any transaction or
other outcome, or that we will realize our strategic and other objectives in connection with any such transaction or outcome.

We face significant competition in the markets we serve and we may not be able to compete successfully.

All of the markets we serve are highly competitive. We compete with manufacturers and distributors, both within and outside the United States. Some of our
competitors may have superior financial, technical, marketing and other resources. In some cases, we face competition from manufacturers in countries able to
produce similar products at lower costs. Price competition or overcapacity may limit our ability to raise prices for our products, may force us to reduce prices
and  may  also  result  in  reduced  levels  of  demand  for  our  products  and  cause  us  to  lose  market  share.  We  also  face  competition  from  the  introduction  by
competitors of new products or technologies that may address our customers’ needs in a better manner, whether based on considerations of pricing, usability,
effectiveness, sustainability, quality or other features or benefits. In addition, to effectively

ITEM 1A.

RISK FACTORS (continued)

-11-

compete, we must continue to develop new products that meet changing consumer preferences and successfully develop, manufacture and market these new
products. If we are not able to successfully commercialize our innovation efforts, we may lose market share. Our inability to effectively compete could result in
the  loss  of  customers  and  reduce  the  sales  of  our  products,  which  could  have  a  material  adverse  impact  on  our  business,  financial  condition  and  results  of
operations.

Emerging issues related to our development, integration and use of artificial intelligence (“AI”) could give rise to legal or regulatory action, damage
our reputation or otherwise materially harm our business.

Our development, integration and use of AI technology in our operations remains in the early phases. We have started to assess the use of AI technology to
drive productivity and data analytics. While we aim to develop, integrate and use AI responsibly, we may ultimately be unsuccessful in identifying or resolving
issues, such as accuracy issues, cybersecurity risks, unintended biases, and discriminatory outputs, before they arise. AI is a new and emerging technology in
early  stages  of  commercial  use  and  presents  a  number  of  risks  inherent  in  its  use,  including,  but  not  limited  to,  ethical  considerations,  public  perception,
intellectual property protection, regulatory compliance, privacy concerns and data security, all of which could have a material adverse effect on our business,
results of operations and financial position. As a result, we cannot predict future developments in AI and related impacts to our business and our industry. If we
are unable to successfully and accurately develop, integrate and use AI technology, as well as address the risks and challenges associated with AI, our business,
results of operations and financial position could be negatively impacted. Additionally, if the content, analyses, or recommendations that AI applications assist
in producing are or are alleged to be deficient, inaccurate, or biased, our reputation, business, financial condition, and results of operations may be adversely
affected.

Climate  change,  weather  conditions  and  storm  activity  could  have  a  material  adverse  impact  on  our  business,  financial  condition  and  results  of
operations.

Climate change could have an impact on several aspects of our business, financial condition and results of operations. Weather phenomena associated with
climate  change,  such  as  flooding  or  altered  storm  activity,  may  impact  our  ability  to  operate  our  manufacturing  facilities  in  some  locations.  In  addition,
customer preferences for lower-carbon and more environmentally friendly solutions could impact demand for our products. Although we believe that some of
our product categories, such as insulation and composites, could experience increased demand due to environmental benefits, such as energy efficiency and
renewable energy, the timing and impact of such increased demand is uncertain.

Weather  conditions  and  the  level  of  severe  storms  can  have  a  significant  impact  on  the  markets  for  residential  and  commercial  construction,  repair  and
improvement projects. These factors could impact our business as follows:

•
•

generally, any weather conditions that slow or limit residential or commercial construction activity can adversely impact demand for our products; and

a portion of our annual product demand is attributable to the repair of damage caused by severe storms. In periods with below average levels of severe
storms, demand for such products could be reduced.

Lower demand for our products as a result of either of these weather-related scenarios could have a material adverse impact on our business, financial condition
and results of operations. Additionally, severely low or high temperatures may lead to significant and immediate spikes in costs of natural gas, electricity and
other commodities that could negatively affect our results of operations.

We will not be insured against all potential losses and could be seriously harmed by natural disasters, catastrophes, pandemics, theft or sabotage.

Many of our business activities globally involve substantial investments in manufacturing facilities and many products are produced at a limited number of
locations. These facilities could be materially damaged by natural disasters such as floods, tornados, hurricanes, fires, earthquakes, pandemics or by theft or
sabotage.  We  could  incur  uninsured  losses  and  liabilities  arising  from  such  events,  including  damage  to  our  reputation,  and/or  suffer  material  losses  in
operational capacity, which could have a material adverse impact on our business, financial condition and results of operations.

LEGAL, REGULATORY AND COMPLIANCE RISKS

We  could  face  potential  product  liability  and  warranty  claims,  we  may  not  accurately  estimate  costs  related  to  such  claims,  and  we  may  not  have
sufficient insurance coverage available to cover such claims.

Our  products  are  used  and  have  been  used  in  a  wide  variety  of  residential,  commercial  and  industrial  applications.  We  face  an  inherent  business  risk  of
exposure to product liability or other claims in the event our products are alleged to be defective or that

ITEM 1A.

RISK FACTORS (continued)

-12-

the use of our products is alleged to have resulted in harm to others or to property. We may, in the future, incur liability if product liability lawsuits against us
are  successful.  Moreover,  any  such  lawsuits,  whether  or  not  successful,  could  result  in  adverse  publicity  to  us,  which  could  cause  our  sales  to  decline. We
maintain insurance coverage to protect us against product liability claims, but that coverage may not be adequate to cover all claims that may arise or we may
not be able to maintain adequate insurance coverage in the future at an acceptable cost. Any liability not covered by insurance or that exceeds our established
reserves could materially and adversely impact our business, financial condition and results of operations.

For example, during the second quarter of 2023, the Company’s subsidiary, Paroc Group OY (“Paroc”), notified the appropriate European maritime regulatory
authorities  that  specific  insulation  products  in  its  marine  insulation  product  line  may  not  meet  certain  fire  safety  requirements  in  accordance  with  their
certifications. Paroc voluntarily withdrew these specific products from the market, issued recalls, and suspended distribution and sales of these products. Paroc
is cooperating with the applicable regulatory and government authorities, and continues to work with its customers and end-users to assist with remediation.
Although we established an estimated liability for expected future costs related to this matter, it is reasonably possible that additional product recall costs could
be incurred that exceed the estimated liability by amounts that could be material to our consolidated financial statements. These actions may also result in harm
to our reputation and results of operations.

In addition, consistent with industry practice, we provide warranties on many of our products. We may experience costs of warranty claims when the product is
not performing to the satisfaction of the claimant even though it has not caused harm to others or property. We estimate our future warranty costs based on
historical  trends  and  product  sales,  but  we  may  fail  to  accurately  estimate  those  costs  and  thereby  fail  to  establish  adequate  warranty  reserves  for  them.
Warranty claims are not insurable.

We may be subject to liability under and may make substantial future expenditures to comply with environmental and emerging product-based laws
and regulations.

Our  manufacturing  facilities  are  subject  to  numerous  foreign,  federal,  state  and  local  laws  and  regulations  relating  to  the  presence  of  hazardous  materials,
pollution  and  the  protection  of  the  environment,  including  those  governing  emissions  to  air,  discharges  to  water,  use,  storage  and  transport  of  hazardous
materials, storage, treatment and disposal of waste, remediation of contaminated sites and protection of worker health and safety. We are also subject to laws,
rules and regulations relating to certain raw materials used in our business or in our products.

Liability under these laws involves inherent uncertainties. Environmental liability estimates may be affected by changing determinations of what constitutes an
environmental exposure or an acceptable level of cleanup. For example, remediation activities generally involve a potential range of activities and costs related
to  soil  and  groundwater  contamination.  This  can  include  pre-cleanup  activities,  such  as  fact  finding  and  investigation,  risk  assessment,  feasibility  studies,
remedial action design and implementation (where actions may range from monitoring to removal of contaminants, to installation of longer-term remediation
systems). Please see “Item 1 - Business - Environmental Control” for information on costs and accruals related to environmental remediation. To the extent that
the required remediation procedures or timing of those procedures change, additional contamination is identified, or the financial condition of other potentially
responsible  parties  is  adversely  affected,  the  estimate  of  our  environmental  liabilities  may  change.  Change  in  required  remediation  procedures  or  timing  of
those procedures at existing legacy sites, or discovery of contamination at additional sites, could result in increases to our environmental obligations. Violations
of environmental, health and safety laws are subject to civil, and, in some cases, criminal sanctions.

As a result of these uncertainties, we may incur unexpected interruptions to operations, fines, penalties or other reductions in income which could adversely
impact our business, financial condition and results of operations. It is possible that new laws and regulations will specifically address climate change, toxic air
emissions, ozone forming emissions and fine particulate matter. New environmental and chemical regulations could impact our ability to expand production or
construct new facilities in every geographic region in which we operate. Continued and increased government and public emphasis on environmental issues is
expected  to  result  in  increased  future  investments  for  environmental  controls  at  ongoing  operations,  which  will  be  charged  against  income  from  future
operations.  Present  and  future  environmental  laws  and  regulations  applicable  to  our  operations,  and  changes  in  their  interpretation,  may  require  substantial
capital  expenditures  or  may  require  or  cause  us  to  modify  or  curtail  our  operations,  which  may  have  a  material  adverse  impact  on  our  business,  financial
condition  and  results  of  operations.  Although  emerging  in  nature,  an  increasing  number  of  laws  and  regulations  focused  on  product  and  chemical  hazards,
including regulations concerning the impact of product manufacturing and use on climate change, and resulting preferential product selection could also impact
our  ability  to  manufacture  and  sell  certain  products  or  require  significant  research  and  development  investment  and  capital  expenditures  to  meet  regulatory
requirements.

ITEM 1A.

RISK FACTORS (continued)

-13-

Proposed  or  future  laws  or  regulations  aimed  at  addressing  climate  change,  including,  but  not  limited  to,  local  building  codes,  Environmental
Protection Agency regulations on greenhouse gas emissions (“GHG”), laws or regulations impacting energy supply, and other laws or regulations, may
materially impact demand for our products or our cost of doing business.

We believe it is likely that the scientific and political attention to issues concerning the extent and causes of climate change will continue, with new and more
restrictive  laws  and  regulations  focusing  on  environmental,  social  and  governance  (“ESG”)  initiatives  that  could  affect  our  financial  condition,  results  of
operations  and  cash  flows.  Foreign,  federal,  state  and  local  regulatory  and  legislative  bodies  have  enacted  or  proposed  various  legislative  and  regulatory
measures relating to increased transparency and standardization of reporting matters that may include climate change, regulating GHG emissions, water usage,
recycling of plastic materials, and energy policies, including waste tax, and other governmental charges and mandates. As a result, we expect to be subject to
overlapping,  yet  distinct,  climate-related  disclosure  requirements  in  multiple  jurisdictions.  Compliance  with  foreign,  federal,  state  and  local  legislation  and
regulations concerning climate-related disclosures, including compliance with the European Commission’s Corporate Sustainability Reporting Directive and
the SEC’s proposed climate disclosure requirements, may result in additional costs and capital expenditures, and the failure to comply with such legislation and
regulations could result in fines to us and could affect our business, financial condition, results of operations and cash flows. We could also face increased costs
related to defending and resolving legal claims and other litigation related to climate change and the alleged impact of our operations on climate change. In
addition, energy prices could increase as a result of climate change legislation or other environmental mandates, which could have an adverse effect on our
results of operations.

In  addition,  from  time  to  time,  we  establish  targets,  strategies  and  expectations  related  to  climate  change  and  other  environmental  matters.  Our  ability  to
achieve any such targets, strategies or expectations is subject to risks and uncertainties, many of which are outside of our control. These risks and uncertainties
include,  but  are  not  limited  to,  our  ability  to  execute  our  strategies  and  achieve  our  goals  within  the  currently  projected  costs  and  expected  timeframes,
availability, use and success of on and off-site renewable energy, evolving regulatory and other standards, processes, and assumptions, the pace of scientific and
technological developments, increased costs and availability of requisite financing, market trends that may alter business opportunities, the conduct of third-
party manufacturers and suppliers, constraints or disruptions to our supply chain, and changes in carbon markets. There are no assurances that we will be able
to successfully execute our strategies and achieve our targets. Failures or delays (whether actual or perceived) to achieve our targets or strategies related to
climate change and other environmental matters could damage our reputation, customer and investor relationships, adversely affect our business, operations
and increase risk of litigation.

Our intellectual property rights may not provide meaningful commercial protection for our products or brands and third parties may assert that we
violate their intellectual property rights, which could have a material adverse impact on our business, financial condition and results of operations.

We  rely  on  our  intellectual  property,  including  numerous  patents,  trademarks,  trade  secrets,  confidential  information,  as  well  as  our  licensed  intellectual
property, to differentiate our products and brands in the marketplace. We monitor and protect against activities that might infringe, dilute, or otherwise harm
our intellectual property and rely on the laws of the United States and other countries to protect our rights. However, in some instances, we may be unaware of
unauthorized  use  of  our  intellectual  property.  To  the  extent  we  cannot  protect  our  innovations  or  are  unable  to  enforce  our  intellectual  property  rights,
unauthorized  use  and  misuse  of  our  intellectual  property  or  innovations  could  harm  our  competitive  position  and  have  a  material  adverse  impact  on  our
business, financial condition and results of operations. In addition, the laws of some foreign jurisdictions provide less protection for our proprietary rights than
the laws of the United States and we therefore may not be able to effectively enforce our intellectual property rights in these jurisdictions. If we are unable to
maintain  certain  exclusive  licenses,  our  brand  recognition  and  sales  could  be  adversely  impacted.  Current  employees,  contractors  and  suppliers  have,  and
former employees, contractors and suppliers may have, access to trade secrets and confidential information regarding our operations that could be disclosed
improperly and in breach of contract to our competitors or otherwise used to harm us.

Third  parties  may  also  claim  that  we  are  infringing  upon  their  intellectual  property  rights.  If  we  are  unable  to  successfully  defend  or  license  such  alleged
infringing intellectual property or if we are required to substitute similar technology from another source, our operations could be adversely affected. Even if
we  believe  that  such  intellectual  property  claims  are  without  merit,  defending  such  claims  can  be  costly,  time  consuming  and  require  significant  resources.
Claims of intellectual property infringement also may require us to redesign affected products, pay costly damage awards, or face injunctions prohibiting us
from manufacturing, importing, marketing or selling certain of our products. Even if we have agreements to indemnify us, indemnifying parties may be unable
or unwilling to do so.

ITEM 1A.

RISK FACTORS (continued)

-14-

We are subject to various legal and regulatory proceedings, including litigation in the ordinary course of business, and uninsured judgments or a rise
in insurance premiums may have a material adverse impact on our business, financial condition and results of operations.

In  the  ordinary  course  of  business,  we  are  subject  to  various  legal  and  regulatory  proceedings,  which  may  include  but  are  not  limited  to  those  involving
antitrust, tax, trade, environmental, intellectual property, data privacy and other matters, including general commercial litigation. Any claims raised in legal and
regulatory  proceedings,  whether  with  or  without  merit,  could  be  time  consuming  and  expensive  to  defend  and  could  divert  management’s  attention  and
resources. Additionally, the outcome of legal and regulatory proceedings may differ from our expectations because the outcomes of these proceedings are often
difficult  to  predict  reliably.  Various  factors  and  developments  can  lead  to  changes  in  our  estimates  of  liabilities  and  related  insurance  receivables,  where
applicable, or may require us to make additional estimates, including new or modified estimates, that may be appropriate due to a judicial ruling or judgment, a
settlement, regulatory developments or changes in applicable law. A future adverse ruling, settlement or unfavorable development could result in charges that
could have a material adverse effect on our results of operations in any particular period.

In accordance with customary practice, we maintain insurance against some, but not all, of these potential claims. In the future, we may not be able to maintain
insurance at commercially acceptable premium levels. In addition, the levels of insurance we maintain may not be adequate to fully cover any and all losses or
liabilities. If any significant judgment or claim is not fully insured or indemnified against, it could have a material adverse impact on our business, financial
condition and results of operations.

FINANCIAL RISKS

Our level of indebtedness could adversely impact our business, financial condition or results of operations.

At  December  31,  2023,  we  had  total  debt  of  approximately  $3.0  billion.  On  February  8,  2024,  we  entered  into  a  definitive  agreement  to  acquire  Masonite
International Corporation ("Masonite"), subject to the satisfaction or waiver of specified conditions. We expect to incur approximately $3.0 billion of debt to
pay a substantial portion of the purchase price for the acquisition of Masonite, as well as assume up to $875 million of Masonite’s senior unsecured notes.

Our debt level and degree of leverage, particularly if we complete the Masonite acquisition, could have important consequences, including the following:

•

•

•
•

•

our ability to obtain additional debt or equity financing for working capital, capital expenditures, debt service requirements, acquisitions and general
corporate or other purposes may be limited;

a substantial portion of our cash flow could be required for the payment of principal and interest on our indebtedness, and may not be available for
other business purposes;

certain of our available borrowings are at variable rates of interest, exposing us to the risk of increased interest rates to borrow in the future;

if due to liquidity needs we must replace any indebtedness upon maturity, we would be exposed to the risk that we may not be able to refinance such
indebtedness;

our ability to adjust to changing market conditions may be limited and place us at a competitive disadvantage compared to our competitors if they
have less debt; and

• we may be vulnerable in a downturn in general economic conditions or in our business, or we may be unable to carry out important capital spending.

The  credit  agreement  governing  our  senior  revolving  credit  facility,  the  indentures  governing  our  senior  notes,  and  the  receivables  purchase  agreement
governing  our  receivables  securitization  facility  contain  various  covenants  that  impose  operating  and  financial  restrictions  on  us  and  our  subsidiaries.
Additionally, instruments and agreements governing our future indebtedness may impose other restrictive conditions or covenants that could restrict our ability
to conduct our business operations or pursue growth strategies.

Downgrades of our credit ratings could adversely impact us.

Our credit ratings are important to our cost of capital. The major debt rating agencies routinely evaluate our debt based on a number of factors, which include
financial strength and business risk as well as transparency with rating agencies and timeliness of financial reporting. A downgrade in our debt rating could
result in increased interest on our existing variable

ITEM 1A.

RISK FACTORS (continued)

-15-

interest rate debt, increased interest and other expenses for future borrowings, and reduced ability for our suppliers to utilize supply chain financing programs.
Downgrades in our debt rating could also restrict our access to capital markets and affect the value and marketability of our outstanding senior notes.

Our operations require substantial capital, leading to high levels of fixed costs that will be incurred regardless of our level of business activity.

Our businesses are capital intensive, and regularly require capital expenditures to expand operations, maintain equipment, increase operating efficiency and
comply with applicable laws and regulations, leading to high fixed costs, including depreciation expense. Increased regulatory requirements for our operations
could lead to additional or higher fixed costs in the future. We are limited in our ability to reduce fixed costs quickly in response to reduced demand for our
products and these fixed costs may not be fully absorbed, resulting in higher average unit costs and lower gross margins if we are not able to offset this higher
unit cost with price increases. Alternatively, we may be limited in our ability to quickly respond to unanticipated increased demand for our products, which
could result in an inability to satisfy demand for our products and loss of market share.

Our ongoing efforts to increase productivity and reduce costs may not result in anticipated savings in operating costs.

Our cost reduction and productivity efforts, including those related to our existing operations, production capacity expansions, new manufacturing platforms, or
other capital expenditures, may not produce anticipated results. Our ability to achieve cost savings and other benefits within expected time frames is subject to
many  estimates  and  assumptions.  These  estimates  and  assumptions  are  subject  to  significant  economic,  competitive,  legal  and  other  uncertainties,  some  of
which  are  beyond  our  control.  If  these  estimates  and  assumptions  are  incorrect,  if  we  experience  delays,  or  if  other  unforeseen  events  occur,  our  business,
financial condition and results of operations could be adversely impacted.

Our results of operations in a given period may be impacted by price volatility in certain renewable-generated energy markets.

In connection with our sustainability goals to reduce GHG and toxic air emissions, we entered into contracts pursuant to which we have agreed to purchase
renewable-generated electricity from third parties. Under these contracts, we do not take physical delivery of renewable-generated electricity. The generated
electricity is instead sold by our counterparties to local grid operators at the prevailing market price and we obtain the associated non-tax renewable energy
credits. The prevailing market pricing for renewable-generated electricity can be affected by factors beyond our control and is subject to significant period over
period volatility. For example, renewable-generated energy output fluctuates due to climactic and other factors beyond our control and can be constrained by
available transmission capacity, thereby significantly impacting pricing. Due to this potential volatility, it is possible that these contracts, or similar contracts
we execute in the future, could have an impact on our results of operations in a given reporting period.

Our hedging activities to address energy price fluctuations may not be successful in offsetting increases in those costs or may reduce or eliminate the
benefits of any decreases in those costs.

To mitigate short-term variation in our operating results due to commodity price fluctuations in certain geographic markets, we may hedge a portion of our
near-term exposure to the cost of energy. The results of our hedging practices could be positive, neutral or negative in any period depending on price changes of
the hedged exposures.

Our hedging activities are not designed to mitigate long-term commodity price fluctuations and, therefore, would not protect us from long-term commodity
price increases. In addition, in the future, our hedging positions may not correlate to our actual energy costs, which would cause acceleration in the recognition
of unrealized gains and losses on our hedging positions in our operating results.

If we were required to write down all or part of our goodwill or other indefinite-lived intangible assets, our results of operations or financial condition
could be materially adversely affected in a particular period.

Declines in our business may result in an impairment of our tangible and intangible assets, which could result in a material non-cash charge. A significant or
prolonged decrease in our market capitalization, including a decline in stock price, a negative long-term performance outlook, or an increase in discount rates
could result in an impairment of our tangible and intangible assets which results when the carrying value of the Company’s assets exceed their fair value.

At least annually, we assess our goodwill and intangible assets for impairment. When we utilize a discounted cash flow methodology to calculate the fair value
of our reporting units, weak demand for a specific product line or business could result

ITEM 1A.

RISK FACTORS (continued)

-16-

in an impairment. Accordingly, any determination requiring the write-off of a significant portion of goodwill or intangible assets could negatively impact our
results of operations.

HUMAN CAPITAL RISKS

We depend on our senior management team and other skilled and experienced personnel to operate our business effectively, and the loss of any of
these  individuals  or  the  failure  to  attract  additional  qualified  personnel  could  adversely  impact  our  business,  financial  condition  and  results  of
operations.

We are highly dependent on the skills and experience of our senior management team and other skilled and experienced personnel. These individuals possess
sales, marketing, manufacturing, logistical, financial, business strategy and administrative skills that are important to the operation of our business. We cannot
assure that we will be able to retain all of our existing senior management personnel and skilled and experienced personnel. The loss of any of these individuals
or an inability to attract additional qualified personnel could prevent us from implementing our business strategy and could adversely impact our business and
our future financial condition or results of operations. The current and future labor markets may impact our ability to retain these individuals.

Labor  shortages  and  increased  turnover  rates,  increased  employee-related  costs,  and  labor  disputes  could  have  a  material  adverse  impact  on  our
operations, results of operations, liquidity and cash flows.

Our operations depend on the availability and relative costs of labor and maintaining good relations with our personnel and the labor unions. Several factors
have had and may continue to have adverse effects on the labor force available to us, including general economic uncertainty, government regulations, laws and
regulations related to workers’ health and safety, inflation, wage and hour practices and immigration. Labor shortages and increased turnover rates within our
personnel have led to and could in the future lead to increased costs, such as increased costs associated with training new employees and increased wage rates
to attract and retain employees. An overall or prolonged labor shortage, lack of skilled labor, increased turnover or labor inflation could have a material adverse
impact on our operations, results of operations, liquidity and cash flows.

We are also subject to the risk that labor strikes or other types of conflicts with personnel may arise or that we may become the subject of union organizing
activity at additional facilities. Renewal of collective bargaining agreements typically involves negotiation, with the potential for work stoppages or increased
costs at affected facilities.

Significant changes in the factors and assumptions used to measure our defined benefit plan obligations, actual investment returns on pension assets
and other factors could have a negative impact on our financial condition or liquidity.

We have certain defined benefit pension plans and other post-employment benefit (“OPEB”) plans. Our future funding requirements for defined benefit pension
and OPEB plans depend upon a number of factors and assumptions, including our actual experience against assumptions with regard to interest rates used to
determine  funding  levels,  return  on  plan  assets,  benefit  levels,  participant  experience  (e.g.,  mortality  and  retirement  rates),  health  care  cost  trends,  and
applicable regulatory changes. To the extent actual results are less favorable than our assumptions, there could be a material adverse impact on our financial
condition and results of operations.

Additional risks exist due to the nature and magnitude of our investments, including the implementation of or changes to the investment policy, insufficient
market  capacity  to  absorb  a  particular  investment  strategy  or  high-volume  transactions,  and  the  inability  to  quickly  rebalance  illiquid  and  long-term
investments.

If our cash flows and capital resources are insufficient to fund our pension or OPEB obligations, we could be forced to reduce or delay investments and capital
expenditures, seek additional capital, or restructure or refinance our indebtedness.

RISKS RELATED TO OUR PLANNED ACQUISITION OF MASONITE

Our planned acquisition of Masonite may not occur at all or may not occur in the expected time frame, which may negatively affect the trading prices
of our stock and our future business and financial results.

Completion of the planned acquisition of Masonite is subject to the satisfaction or waiver of customary and other closing conditions. The acquisition is not
assured and is subject to risks and uncertainties, including the risk that the necessary regulatory approvals or shareholder approval will not be obtained or that
other closing conditions will not be satisfied. We cannot predict whether and when such approvals will be received, or such conditions will be satisfied.

ITEM 1A.

RISK FACTORS (continued)

-17-

Our obligation to complete the planned acquisition of Masonite is not subject to a financing condition.

Our obligation to complete the planned acquisition of Masonite is not subject to a financing condition. We have obtained committed financing for $3.0 billion
to pay a substantial portion of the purchase price for the acquisition of Masonite. If any of the banks in the committed financing facility are unable to perform
their commitments, we may be required to finance a portion of the purchase price of the planned acquisition at interest rates higher than currently expected.

We may not realize the growth opportunities and cost synergies that are anticipated from the planned acquisition of Masonite.

The  benefits  that  are  expected  to  result  from  the  planned  acquisition  of  Masonite  will  depend,  in  part,  on  our  ability  to  realize  the  anticipated  growth
opportunities and cost synergies as a result of the planned acquisition. Our success in realizing these growth opportunities and cost synergies, and the timing of
this realization, depends on the successful integration of Masonite. There can be no assurance that we will successfully or cost-effectively integrate Masonite.
The failure to do so could have a material adverse effect on our business, financial condition, and results of operations.

Even if we are able to integrate Masonite successfully, this integration may not result in the realization of the full benefits of the growth opportunities and cost
synergies that we currently expect from this integration, and we cannot guarantee that these benefits will be achieved within anticipated time frames or at all.
For  example,  we  may  not  be  able  to  eliminate  duplicative  costs.  Additionally,  we  may  incur  substantial  expenses  in  connection  with  the  integration  of
Masonite. While it is anticipated that certain expenses will be incurred to achieve cost synergies, such expenses are difficult to estimate accurately, and may
exceed current estimates. Accordingly, the benefits from the planned acquisition may be offset by costs incurred to, or delays in, integrating the businesses.

RISKS RELATED TO OWNERSHIP OF OUR COMMON STOCK

The market price of our common stock is subject to volatility.

The market price of our common stock could be subject to wide fluctuations in response to numerous factors, many of which are beyond our control. These
factors include actual or anticipated variations in our operational results and cash flow, our earnings relative to our competition, changes in financial estimates
by securities analysts, trading volume, sales by holders of large amounts of our common stock, short selling, market conditions within the industries in which
we  operate,  seasonality  of  our  business  operations,  the  general  state  of  the  securities  markets  and  the  market  for  stocks  of  companies  in  our  industry,
governmental legislation or regulation and currency and exchange rate fluctuations, as well as general economic and market conditions, such as recessions.

We are a holding company with no operations of our own and depend on our subsidiaries for cash.

As  a  holding  company,  most  of  our  assets  are  held  by  our  direct  and  indirect  subsidiaries  and  we  will  primarily  rely  on  dividends  and  other  payments  or
distributions  from  our  subsidiaries  to  meet  our  debt  service  and  other  obligations  and  to  enable  us  to  pay  dividends. The  ability  of  our  subsidiaries  to  pay
dividends or make other payments or distributions to us will depend on their respective operating results and may be restricted by, among other things, the laws
of  their  jurisdiction  of  organization  (which  may  limit  the  amount  of  funds  available  for  the  payment  of  dividends  or  other  payments),  agreements  of  those
subsidiaries,  agreements  with  any  co-investors  in  non-wholly-owned  subsidiaries,  the  terms  of  our  credit  and  receivables  facilities  and  senior  notes  and  the
covenants of any future indebtedness we or our subsidiaries may incur.

Provisions in our amended and restated certificate of incorporation and bylaws or Delaware law may discourage, delay or prevent a change in control
of the Company or changes in our management and therefore depress the trading price of our common stock.

Our  amended  and  restated  certificate  of  incorporation  and  bylaws  contain  provisions  that  could  depress  the  trading  price  of  our  common  stock  through
provisions  that  may  discourage,  delay  or  prevent  a  change  in  control  of  the  Company  or  changes  in  our  management  that  our  stockholders  may  deem
advantageous.

Additionally, we are subject to Section 203 of the Delaware General Corporation Law, which generally prohibits a Delaware corporation from engaging in any
of a broad range of business combinations with any “interested” stockholder for a period of three years following the date on which the stockholder became an
“interested” stockholder and which may discourage, delay or prevent a change in control of our company.

CYBERSECURITY

Risk Management and Strategy

We have a range of security measures that are designed to protect against the unauthorized access to and misappropriation of our information, corruption of
data,  intentional  or  unintentional  disclosure  of  confidential  information,  or  disruption  of  operations.  These  security  measures  include  controls,  security
processes  and  monitoring  of  our  manufacturing  systems.  We  have  cloud  security  tools  and  governance  processes  designed  to  assess,  identify  and  manage
material risks from cybersecurity threats. In addition, we maintain an information security training program designed to address phishing and email security,
password security, data handling security, cloud security, operational technology security processes, and cyber-incident response and reporting processes.

Our  cybersecurity  strategy  includes  defense  in  depth,  zero  trust,  and  standards-based  controls  intended  to  protect  our  information  technology  systems.  We
perform incident response tabletop exercises that include members of the Company’s senior management team to validate, test, and assess the effectiveness and
adequacy of certain roles and decision-making processes in the event of a cybersecurity incident. We also assess, identify, and manage cyber risk associated
with divestiture and merger and acquisition activities.

The  oversight  of  our  cybersecurity  risk  management  process  is  integrated  into  our  overall  risk  management  process. The  risk  committee  is  responsible  for
overseeing  and  monitoring  our  risk  assessment  and  mitigation-related  actions,  including  with  respect  to  cybersecurity  risks.  The  risk  committee  is  not  a
committee of our Board of Directors. It is a cross-functional committee that includes members across many areas of expertise and is structurally independent of
our business lines. The risk committee’s membership is designed to provide diversity of thought and perspective related to risk, including cybersecurity risks.
The  risk  committee  identifies  risks  and  mitigation  strategies,  and  it  provides  key  updates  to  executive  officers  and  the Audit  Committee  of  our  Board  of
Directors.

We  use  third-party  service  providers  to  execute  certain  business  processes,  maintain  certain  information  systems  and  infrastructure,  evaluate  defenses,  and
implement recommendations. We periodically have external information security assessments performed by third parties to analyze our information technology
systems and to stay informed of information security risks. Additionally, we have a supplier validation process, which provides for review and approval by our
cybersecurity group for cloud services.

Although we experience cybersecurity incidents from time to time as part of our operations, we have not experienced any information security breach that had,
or is reasonably likely to have, a material impact on our business strategy, results of operations or financial condition. Any breach of our security measures, or
those of our third-party service providers, could result in unauthorized access to and misappropriation of our information, corruption of data or disruption of
systems, operations or transactions, any of which could have a material adverse effect on our business strategy, results of operations or financial condition. See
“Risk Factors” on page 9 of this Form 10-K for further discussion of the risks related to cybersecurity threats.

Governance

The  Board  of  Directors  is  responsible  for  overseeing  risk  for  the  Company  and  has  delegated  to  the  Audit  Committee  responsibility  for  overseeing  the
cybersecurity risk management strategy for the Company. The Audit Committee receives regular updates on our cybersecurity risk management process from
members  of  management,  including  our  Chief  Information  Officer  (“CIO”).  The  Audit  Committee  review  our  comprehensive  cybersecurity  framework,
including reviewing our cybersecurity reporting protocol that provides for the notification, escalation and communication of significant cybersecurity events to
a crisis management team and appropriate levels of management, including our CIO, as well as to the Audit Committee. Management also provides the Audit
Committee with a cybersecurity dashboard, which the full Board of Directors can access as well. Additionally, the Audit Committee regularly provides updates
to the Board on the status of the Company’s cybersecurity risk management process.

The  Company’s  cybersecurity  program  is  overseen  by  our  CIO,  who  is  responsible  for  global  information  technology,  including  cybersecurity.  Our  Vice
President, Global Information Security, is primarily responsible for assessing and managing material risks from cybersecurity threats, including monitoring the
measures used for prevention, detection, mitigation and remediation of cybersecurity incidents. The information security organization is comprised of internal
Owens Corning employees and external security suppliers who provide security monitoring and response. Our Global Information Services team is regularly
engaged in cybersecurity training and awareness and incorporates relevant reviews in technology design and development.

The Company retained 15,008 shares surrendered to satisfy tax withholding obligations in connection with the vesting of restricted stock units granted to
our employees.

The Board of Directors approved two share repurchase programs in 2022 under which the Company is authorized to repurchase up to an aggregate of 20
million shares of the Company's outstanding common stock (the “Repurchase Authorization”). The Repurchase Authorization enables the Company to
repurchase shares through the open market, privately negotiated or other transactions. The actual number of shares repurchased will depend on timing,
market conditions and other factors and will be at the Company's discretion. The Company repurchased 1.8 million shares of its common stock for $238
million, inclusive of applicable taxes, during the three months ended December 31, 2023 under the Repurchase Authorization. As of December 31, 2023,
8.9 million shares remain available for repurchase under the Repurchase Authorization.

Performance Graph

The annual changes for the five-year period shown in the graph on this page are based on the assumption that $100 had been invested in Owens Corning (OC)
stock, the Standard & Poor’s 500 Stock Index (“S&P 500”), and a peer group index on December 31, 2018, and that all quarterly dividends were reinvested.
The total cumulative dollar returns shown on the graph represent the value that such investments would have had on December 31, 2023. We chose to use a
self-selected peer group consisting of the companies noted below to include in the performance graph as we believe this peer group aligns with our specific
industry,  markets,  and  global  exposure.  The  criteria  used  in  determining  this  peer  group  included  the  size  of  the  companies  (measured  in  terms  of  annual
revenue  and  market  capitalization),  industries  and  geographies  in  which  the  companies  operate,  stock  price  correlation  and  volatility  relative  to  Owens
Corning, and increased representation of comparator companies used by shareholder advisory firms.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

-26-

This  Management’s  Discussion  and Analysis  (“MD&A”)  is  intended  to  help  investors  understand  Owens  Corning,  our  operations  and  our  present  business
environment. MD&A is provided as a supplement to, and should be read in conjunction with, our Consolidated Financial Statements and the accompanying
Notes thereto contained in this report. Unless the context requires otherwise, the terms “Owens Corning,” “Company,” “we,” “its,” and “our” in this Annual
Report on Form 10-K refer to Owens Corning and its subsidiaries.

This section of this Annual Report on Form 10-K generally discusses 2023 and 2022 items and year-to-year comparisons between 2023 and 2022. Discussions
of 2021 items and year-to-year comparisons between 2022 and 2021 that are not included in this Form 10-K can be found in “Management's Discussion and
Analysis  of  Financial  Condition  and  Results  of  Operations”  in  Part  II,  Item  7  of  the  Company's  Annual  Report  on  Form  10-K  for  the  fiscal  year  ended
December 31, 2022.

GENERAL

Owens Corning is a global building and construction materials leader committed to building a sustainable future through material innovation. The Company
has three reporting segments: Roofing, Insulation and Composites. Through these lines of business, the Company manufactures and sells products worldwide.
We are a market leader in many of our major product categories.

EXECUTIVE OVERVIEW

Net  earnings  attributable  to  Owens  Corning  were  $1,196  million  in  2023,  compared  to  $1,241  million  in  2022. The  Company  generated  $1,805  million  in
adjusted  earnings  before  interest  and  taxes  (“Adjusted  EBIT”)  in  2023  compared  to  $1,762  million  in  2022.  See  the Adjusted  Earnings  Before  Interest  and
Taxes paragraph of the MD&A for further information regarding Adjusted EBIT, including the reconciliation to net earnings attributable to Owens Corning.
Segment earnings before interest and taxes (“EBIT”) performance compared to 2022 increased $343 million in our Roofing segment, increased $7 million in
our  Insulation  segment  and  decreased  $256  million  in  our  Composites  segment. Within  our  Corporate,  Other  and  Eliminations  category,  General  corporate
expenses and other increased by $51 million.

Cash and cash equivalents were $1.6 billion as of December 31, 2023, compared to $1.1 billion as of December 31, 2022. In 2023, the Company's operating
activities provided $1,719 million of cash flow, compared to $1,760 million in 2022.

On  February  8,  2024,  the  Company  entered  into  a  definitive  agreement  to  purchase  all  of  the  outstanding  shares  of  Masonite.  The  purchase  price  for  the
acquisition of Masonite is approximately $3.9 billion in cash, which we expect to fund with cash on hand and new committed financing. Masonite is a leading
global  designer,  manufacturer,  marketer  and  distributor  of  interior  and  exterior  doors  and  door  systems  for  the  new  construction  and  repair,  renovation  and
remodeling sectors of the residential and non-residential building construction markets. The transaction was unanimously approved by the board of directors of
both  companies  and  is  expected  to  close  mid-2024,  subject  to  regulatory  and  other  customary  closing  conditions,  including  the  approval  of  Masonite
shareholders.

On February 9, 2024, the Company announced the decision to review strategic alternatives for its global glass reinforcements (“GR”) business, consistent with
our strategy to focus on building and construction materials. The GR business, which operates within our Composites segment, supplies a wide variety of glass
fiber products for applications in wind energy, infrastructure, industrial, transportation, and consumer markets. The GR business generates annual revenues of
approximately $1.3 billion and has operations in 11 countries, with 18 manufacturing facilities. While a range of options are under consideration, including a
potential sale, spin-off or other strategic option, there can be no assurance that the strategic review will result in any transaction or other outcome.

In the fourth quarter of 2023, the Company entered into two agreements to purchase non-participating annuity contracts from insurance companies to transfer
$291 million of the Company's outstanding pension projected benefit obligations related to certain U.S. and non-U.S. pension plans. These transactions were
funded with pension plan assets of $268 million. As a result of these transactions, the Company recognized a pre-tax settlement charge of $145 million in the
fourth  quarter  of  2023  from  the  accelerated  recognition  of  a  pro  rata  portion  of  plan  actuarial  losses.  This  charge  was  recorded  in  Non-operating  expense
(income), net on the Consolidated Statements of Earnings. These transactions did not have a material effect on the plans' funded statuses.

During  the  second  quarter  of  2023,  the  Company’s  subsidiary,  Paroc  Group  OY  (“Paroc”),  which  the  Company  acquired  in  2018,  notified  the  appropriate
European  maritime  regulatory  authorities  that  specific  products  in  its  marine  insulation  product  line  may  not  meet  certain  fire  safety  requirements  in
accordance with their certifications. Paroc voluntarily withdrew these specific products from the market, issued recalls, and suspended distribution and sales of
these products. Paroc continues to cooperate with the applicable regulatory and government authorities and work with its customers and end-users to assist with
remediation. During 2023, the Company established an estimated liability for expected future costs related to the marine recall on our Consolidated Balance
Sheet as of December 31, 2023.

As  part  of  its  review  of  the  Paroc  insulation  product  portfolio,  the  Company  discovered  potential  nonconformances  relating  to  certain  ventilation  duct
insulation  products.  In  January  2024,  Paroc  suspended  sales  of  the  affected  insulation  products  as  a  precautionary  measure  while  it  reviews  the  potential
nonconformances. The Company is continuing its review.

In May 2023, the Company made the decision to exit the Protective Packaging business within the Roofing segment, including the production and sale of wood
packaging,  metal  packaging  and  custom  products.  Exiting  Protective  Packaging  will  allow  the  Company  to  focus  resources  on  the  growth  of  its  building
materials products, which supports the future growth aspirations of the enterprise. With the exit of the Protective Packaging business, the Company closed its
plants in Dorval, Quebec and Mission, British Columbia, Canada. The Company also ceased operations at its Qingdao, China facility. In connection with the
exit of the Protective Packaging business, the Company estimates that it will incur cash charges of approximately $15 million, primarily related to severance
and  other  exit  costs. Additionally,  the  Company  expects  to  incur  total  non-cash  charges  in  the  range  of  $70  to  $75  million,  primarily  related  to  accelerated
depreciation of property, plant and equipment and accelerated amortization of definite-lived intangibles. The Company has exited the majority of the business
and  expects  to  generate  savings  of  approximately  $7  million  annually  beginning  2024.  During  the  twelve  months  ended  2023,  the  Company  recorded
$78 million of charges, primarily related to accelerated depreciation, accelerated amortization and severance.

In March 2023, the Company finalized the sale of its Insulation site in Santa Clara, California for total proceeds of $234 million, net of transaction fees. Total
proceeds  included  a  non-refundable  deposit  of  $50  million  received  in  the  third  quarter  2021.  As  a  result,  the  Company  recognized  a  pre-tax  gain  of
$189 million in the first quarter of 2023, which is recorded in Gain on sale of site on the Consolidated Statements of Earnings.

In  2023,  the  Company  repurchased  5.4  million  shares  of  the  Company’s  common  stock  for  $629  million,  inclusive  of  applicable  taxes,  under  previously
announced repurchase authorizations. As of December 31, 2023, 8.9 million shares remained available for repurchase under the repurchase authorizations.

The Consolidated Results discussion below provides a summary of our results and the trends affecting our business, and should be read in conjunction with the
more detailed Segment Results discussion that follows.

NET SALES

Net sales decreased $84 million in 2023 compared to 2022. The decrease in net sales was driven by lower sales volumes in both Insulation and Composites
segments, partially offset by higher selling prices across all three segments. The remaining variance was driven by favorable customer mix, which was partially
offset by the unfavorable net impact of acquisitions and divestitures.

GROSS MARGIN

Gross margin increased $67 million in 2023 compared to 2022. The increase in gross margin was driven by higher selling prices across all three segments,
which  was  partially  offset  by  lower  sales  volumes  in  both  Insulation  and  Composites  segments  and  higher  production  downtime.  Favorable  delivery  and
favorable customer and product mix more than offset higher input costs and the unfavorable net impact of acquisitions and divestitures.                             

MARKETING AND ADMINISTRATIVE EXPENSES

Marketing and administrative expenses increased $28 million in 2023 compared to 2022. The increase was driven primarily by ongoing inflationary pressures,
as well as higher general corporate expenses.

GAIN ON EQUITY METHOD INVESTMENT

In 2022, the Company recognized a non-cash gain of $130 million from the remeasurement of the previously held equity method investment in Fiberteq, LLC
upon the Company’s acquisition of the remaining 50% of the joint venture with IKO.

GAIN ON SALE OF SITE

In the first quarter of 2023, the Company finalized the sale of the Company's Insulation site in Santa Clara, California resulting in the recognition of a pre-tax
gain of $189 million.

OTHER EXPENSE (INCOME), NET

Other expense (income), net decreased $17 million in 2023 compared to 2022. Higher restructuring costs, lower gains on the sale of precious metals and the
establishment  of  the  estimated  liability  for  the  Paroc  marine  recall  matter  in  2023  were  more  than  offset  by  the  favorable  comparison  year-over-year  to
indefinite-lived intangible asset impairment charges of $96 million and the net loss from divestiture related activities.

NON-OPERATING EXPENSE (INCOME), NET

Non-operating expense (income), net increased $154 million in 2023 compared to 2022. The increase was driven by the pension settlement loss in the fourth
quarter of 2023.

INTEREST EXPENSE, NET

Interest expense, net decreased $33 million in 2023 compared to 2022. The decrease was driven by higher interest income related to the increase in cash and
interest rates, as well as higher capitalized interest resulting from higher construction in progress balances.

INCOME TAX EXPENSE

Income tax expense for 2023 was $401 million compared to $373 million in 2022. The Company’s effective tax rate for 2023 was 25% on pre-tax income of
$1,591 million. The difference between the 25% effective tax rate and the U.S. federal statutory tax rate of 21% is primarily due to U.S. state and local income
tax expense.

The  Company’s  effective  tax  rate  for  2022  was  23%  on  pre-tax  income  of  $1,614  million. The  difference  between  the  23%  effective  tax  rate  and  the  U.S.
federal statutory tax rate of 21% is primarily attributable to U.S. state and local income tax expense, adjustments to R&D tax credits, and other adjustments.

See Note 20 for additional information.

Restructuring, Acquisition and Divestiture-Related Costs

The Company has incurred restructuring, transaction and integration costs related to acquisitions and divestitures, along with restructuring and other exit costs
in connection with its global cost reduction, product line and productivity initiatives and growth strategy. These costs are recorded within Corporate, Other and
Eliminations. Please refer to Note 12 of the Consolidated Financial Statements for further information on the nature of these costs.

Adjusted Earnings Before Interest and Taxes (“Adjusted EBIT”)

Adjusted EBIT is a non-GAAP measure that excludes certain items that management does not allocate to our segment results because it believes they are not
representative  of  the  Company’s  ongoing  operations. Adjusted  EBIT  is  used  internally  by  the  Company  for  various  purposes,  including  reporting  results  of
operations to the Board of Directors of the Company, analysis of performance and related employee compensation measures. Although management believes
that these adjustments result in a measure that provides a useful representation of our operational performance, the adjusted measure should not be considered
in isolation or as a substitute for Net earnings (loss) attributable to Owens Corning as prepared in accordance with accounting principles generally accepted in
the United States.

Segment Results

EBIT by segment consists of net sales less related costs and expenses and is presented on a basis that is used internally for evaluating segment performance.
Certain items, such as general corporate expenses or income and certain other expense or income items, are excluded from the internal evaluation of segment
performance.  Accordingly,  these  items  are  not  reflected  in  EBIT  for  our  reportable  segments  and  are  included  in  the  Corporate,  Other  and  Eliminations
category, which is presented following the discussion of our reportable segments.

Earnings before interest, taxes, depreciation and amortization (“EBITDA”) by segment is a non-GAAP measure that consists of EBIT plus depreciation and
amortization. Segment EBITDA is used internally by the Company for analysis of our performance.

In our Roofing segment, net sales increased $372 million in 2023 compared to 2022 due to higher sales volumes of approximately 5% and higher selling prices
of $166 million. Favorable product and customer mix were partially offset by lower third-party asphalt sales of $44 million.

EBIT

In  our  Roofing  segment,  EBIT  increased  $343  million  in  2023  compared  to  2022  driven  primarily  by  higher  selling  prices  of  $166  million. The  remaining
improvement was driven by favorable input costs and delivery of $80 million, higher sales volumes, and favorable customer and product mix of $48 million,
which were partially offset by higher selling, general and administrative expenses and $8 million of higher production costs.

OUTLOOK

In our Roofing segment, the Company expects North American new residential construction market to temporarily remain soft. Other uncertainties that may
impact  Roofing  demand  include  demand  from  storms  and  other  weather-related  events,  demand  from  repair  and  remodeling  activity,  competitive  pricing
pressure and the cost and availability of raw materials, particularly asphalt. The Company will continue to focus on managing costs, capital expenditures and
working capital.

In our Insulation segment, 2023 net sales decreased $46 million compared to 2022. The decrease was driven by lower sales volumes of approximately 10%,
which more than offset higher selling prices of $245 million and favorable customer and product mix. The favorable net impact of acquisitions and divestitures
and $5 million of favorable impact of translating sales denominated in foreign currencies into United States dollars also contributed to the offset of decreased
volumes.

EBIT

In our Insulation segment, EBIT increased $7 million in 2023 compared to 2022. Higher selling prices of $245 million more than offset lower sales volumes
and $57 million of input cost inflation. Higher manufacturing costs of $29 million and higher production downtime were partially offset by favorable delivery
of  $21  million  and  favorable  customer  and  product  mix.  The  remaining  variance  was  driven  by  the  $7  million  negative  impact  of  translating  profits
denominated in foreign currencies into United States dollars and higher start-up costs.

OUTLOOK

The  outlook  for  Insulation  demand  is  driven  by  North  American  new  residential  construction,  remodeling  and  repair  activity,  as  well  as  commercial  and
industrial construction activity in the United States, Canada, Europe, Asia-Pacific and Latin America. Demand in commercial and industrial insulation markets
is most closely correlated to industrial production growth and overall economic activity in the global markets we serve. Demand for residential insulation is
most closely correlated to U.S. housing starts.

During  the  fourth  quarter  of  2023,  the  average  Seasonally Adjusted Annual  Rate  (“SAAR”)  of  U.S.  housing  starts  was  approximately  1.454  million  starts,
which is up from 1.403 million starts in the fourth quarter of 2022.

The Company expects both the North American new residential construction market and global commercial and industrial construction markets to temporarily
remain  soft  with  the  weaker  macro-economic  outlook,  higher  interest  rates  and  continued  input  cost  inflation.  The  Company  remains  focused  on  managing
costs, capital expenditures, and working capital.

Net  sales  in  our  Composites  segment  decreased  $374  million  in  2023  compared  to  2022.  The  decrease  was  primarily  driven  by  lower  sales  volumes  of
approximately 12% and the net unfavorable impact of divestitures and acquisitions. Unfavorable customer mix of $16 million was partially offset by higher
selling prices of $9 million and the favorable impact of translating sales denominated in foreign currencies into United States dollars.

EBIT

EBIT in our Composites segment decreased $256 million in 2023 compared to 2022. The decrease was driven by lower sales volumes, $83 million of higher
production downtime and the net unfavorable impact of divestitures and acquisitions of $37 million. Higher input cost inflation of $41 million was offset by
favorable delivery and higher selling prices. The remaining variance was driven by unfavorable customer mix, higher rebuild costs and the $5 million negative
impact of translating profits denominated in foreign currencies into United States dollars, which was partially offset by favorable manufacturing costs.

OUTLOOK

Global glass reinforcements market demand has several economic indicators, including residential, non-residential construction and manufacturing production
indices, as well as global wind installations. The Company anticipates continued impacts of economic uncertainty in a dynamic global environment, as well as
competitive pricing pressure. The Company remains focused on managing costs, capital expenditures, and working capital.

The  impact  on  EBIT  from  Corporate,  Other  and  Eliminations  in  2023  was  $150  million  higher  compared  to  2022.  The  increase  was  primarily  driven  by
pension settlement losses and higher restructuring costs, partially offset by the gain on sale of the Santa Clara, California site.

General corporate expense and other in 2023 was $51 million higher than in 2022.

OUTLOOK

In 2024, we expect general corporate expenses to range between $240 and $250 million, without considering the effect of the planned acquisition of Masonite.

LIQUIDITY, CAPITAL RESOURCES AND OTHER RELATED MATTERS

Liquidity

The Company's primary sources of liquidity are its balance of Cash and cash equivalents of $1.6 billion as of December 31, 2023, its Senior Revolving Credit
Facility and its Receivables Securitization Facility (each as defined below).

The Company has an $800 million senior revolving credit facility (the “Senior Revolving Credit Facility”) that has been amended from time to time, which
matures in July 2026.

The Company has a $280 million securitization facility (the “Receivables Securitization Facility”) that has been amended from time to time, which matures in
April 2024.

The Receivables Securitization Facility and Senior Revolving Credit Facility mature in 2024 and 2026, respectively. The Company's 4.2% senior notes mature
in  the  fourth  quarter  of  2024. As  of  December  31,  2023,  the  Company  had  $3.0  billion  of  total  debt  and  cash  and  cash  equivalents  of  $1.6  billion.  The
agreements governing our Senior Revolving Credit Facility and Receivables Securitization Facility contain various covenants that we believe are usual and
customary. These covenants include a maximum allowed leverage ratio. We were in compliance with these covenants as of December 31, 2023.

On  February  8,  2024,  the  Company  entered  into  a  commitment  letter  with  Morgan  Stanley  Senior  Funding,  Inc.  (“MSSF”),  pursuant  to  which  MSSF  has
committed  to  provide,  subject  to  the  satisfaction  of  customary  closing  conditions,  a  364-day  senior  unsecured  term  loan  facility  in  an  aggregate  principal
amount of up to $3.0 billion for purposes of funding a substantial portion of the Masonite acquisition. We expect to assume up to $875 million of Masonite’s
outstanding senior unsecured notes. On February 9, 2024, the three major credit rating agencies reaffirmed our investment-grade debt ratings.

Cash and cash equivalents held by foreign subsidiaries may be subject to foreign withholding taxes upon repatriation to the U.S. As of December 31, 2023 and
December  31,  2022,  the  Company  had  $114  million  and  $188  million,  respectively,  in  cash  and  cash  equivalents  in  certain  of  its  foreign  subsidiaries. The
Company continues to assert indefinite reinvestment in accordance with Accounting Standards Codification (“ASC”) 740 based on the laws as of enactment of
the tax legislation commonly known as the U.S. Tax Cuts and Jobs Act of 2017.

As a holding company, we have no operations of our own and most of our assets are held by our direct and indirect subsidiaries. Dividends and other payments
or distributions from our subsidiaries will be used to meet our debt service and other obligations and to enable us to pay dividends to our stockholders. Please
refer to the Risk Factors disclosed in Item 1A of this Annual Report on Form 10-K for details on the factors that could inhibit our subsidiaries' abilities to pay
dividends or make other distributions to the parent company.

We have no material off-balance sheet arrangements that have or are reasonably likely to have a material current or future effect on our financial condition,
results of operations, liquidity, capital expenditures or other resources.

Material Cash Requirements

Our anticipated uses of cash include capital expenditures, working capital needs, share repurchases, meeting financial obligations, payments of any dividends
authorized by our Board of Directors, acquisitions, including the planned acquisition of Masonite, restructuring actions and pension contributions. We expect
that our cash on hand, coupled with future cash flows from operations and other available sources of liquidity, including our Senior Revolving Credit Facility
and  our  Receivables  Securitization  Facility,  will  provide  ample  liquidity  to  enable  us  to  meet  our  cash  requirements  for  at  least  the  next  12  months  and
foreseeable future thereafter. We expect to use cash on hand and new committed financing to fund the purchase price of the Masonite acquisition and for any
required repurchases of Masonite's outstanding senior unsecured notes.

The following discussion of material cash requirements evaluates known contractual and other obligations, but does not include amounts that are contingent on
events  or  other  factors  that  are  uncertain  or  unknown  at  this  time  including  legal  contingencies,  and  uncertain  tax  positions  among  others.  The  amounts
presented are based on various estimates, including estimates regarding the timing of payments, prevailing interest rates, the occurrence of certain events and
other factors. Actual results may vary materially from the amounts discussed below.

Capital Expenditures: Our capital expenditures are primarily related to the maintenance and rebuild of our long-term assets, as well as investing in projects that
support growth and innovation to further our enterprise strategy. Our capital expenditures on a

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS (continued)

cash basis were $526 million in 2023. Without considering the effect of the planned acquisition of Masonite, we expect to have capital expenditures on a cash
basis  of  approximately  $550  million  in  2024.  The  anticipated  increase  in  capital  expenditures  in  2024  is  primarily  driven  by  growth,  manufacturing
productivity and sustainability projects across all three segments. We expect that capital expenditures will be funded through cash flows from operations. See
Note 2 and Note 6 of the Consolidated Financial Statements for additional information on property, plant and equipment.

Long-term debt obligations, including current portion of long-term debt: As of December 31, 2023, total long-term debt of $3.0 billion primarily consists of
various  outstanding  senior  notes. The  current  portion  of  long-term  debt  includes  $399  million  of  4.2%  senior  notes  maturing  in  the  fourth  quarter  of  2024.
Further  discussion  of  the  amount  and  timing  of  the  future  scheduled  maturities  of  our  senior  notes  can  be  found  in  Note  13  of  the  Consolidated  Financial
Statements. There were no borrowings on our Senior Revolving Credit Facility or our Receivables Securitization Facility as of December 31, 2023.

Interest  on  debt:  We  are  obligated  to  make  periodic  interest  payments  at  fixed  rates,  depending  on  the  terms  of  the  applicable  debt  agreements.  Based  on
interest rates and scheduled maturities as of December 31, 2023, these interest obligations range from $99 million to $130 million annually over the next five
years.

Finance  lease  obligations:  Our  finance  lease  obligations  primarily  consist  of  real  estate,  oxygen  plants,  computers  and  software,  and  fleet  vehicles. As  of
December 31, 2023 we had a total of $196 million of minimum finance lease payments. Further discussion of the future maturities of these lease liabilities can
be found in Note 9 of the Consolidated Financial Statements.

Operating lease obligations: Our operating lease obligations primarily consist of real estate and material handling equipment. As of December 31, 2023, we
had a total of $248 million of minimum operating lease payments. Further discussion of the future maturities of these lease liabilities can be found in Note 9 of
the Consolidated Financial Statements.

Purchase  obligations:  Purchase  obligations  are  commitments  to  suppliers  to  purchase  goods  or  services,  and  include  take-or-pay  arrangements,  capital
expenditures,  and  contractual  commitments  to  purchase  equipment. As  of  December  31,  2023,  the  total  of  these  obligations  was  $328  million,  inclusive  of
$241 million payable in the next 12 months. The Company did not include ordinary course of business purchase orders in this amount as the majority of such
purchase orders may be canceled and are reflected in historical operating cash flow trends. The Company does not believe such purchase orders will adversely
affect our liquidity position.

Pension Contributions: The Company has several defined benefit pension plans. The Company made cash contributions of $18 million and $8 million to the
plans during the twelve months ended December 31, 2023 and 2022, respectively. The Company expects to contribute $20 million in cash to its pension plans
during  2024. Actual  contributions  to  the  plans  may  change  as  a  result  of  several  factors,  including  changes  in  laws  that  impact  funding  requirements.  The
ultimate cash flow impact to the Company, if any, of the pension plan liability and the timing of any such impact will depend on numerous variables, including
future  changes  in  actuarial  assumptions,  legislative  changes  to  pension  funding  laws,  and  market  conditions.  Further  discussion  of  the  Company's  defined
benefit pension plans can be found in Note 14 of the Consolidated Financial Statements.

Other Strategic Uses of Cash: We have outstanding share repurchase authorizations and will evaluate and consider repurchasing shares of our common stock,
as well as payments of any dividends authorized by our Board of Directors, strategic acquisitions, joint ventures, debt repurchases or repayments and other
transactions  to  create  stockholder  value  and  enhance  financial  performance.  Such  transactions  may  require  cash  expenditures  beyond  current  sources  of
liquidity or generated proceeds.

Supplier Finance Programs

We review supplier terms and conditions on an ongoing basis, and have negotiated payment terms extensions in recent years in connection with our efforts to
reduce  working  capital  and  improve  cash  flow.  Separate  from  those  terms  extension  actions,  certain  of  our  subsidiaries  have  entered  into  paying  agency
agreements with third-party administrators. These voluntary supply chain finance programs (collectively, the “Programs”) generally give participating suppliers
the ability to sell, or otherwise pledge as collateral, their receivables from the Company to the participating financial institutions, at the sole discretion of both
the suppliers and financial institutions. The Company is not a party to the arrangements between the suppliers and the financial institutions. The Company’s
obligations to its suppliers, including amounts due and scheduled payment dates, are not impacted by the suppliers’ decisions to sell, or otherwise pledge as
collateral, amounts under these arrangements. The Company's payment terms to the financial institutions, including the timing and amount of payments, are
based on the original supplier invoices. One of our Programs includes a parent guarantee to the participating financial institution for a certain U.S. subsidiary
that, at the time of the respective Program’s inception in 2015, was a guarantor subsidiary of the Company’s Credit Agreement. The obligations are presented
as Accounts payable within Total current liabilities on the Consolidated Balance Sheets and all activity related to the obligations is presented within operating
activities on the Consolidated Statements of Cash Flow.

The desire of suppliers and financial institutions to participate in the Programs could be negatively impacted by, among other factors, the availability of capital
committed  by  the  participating  financial  institutions,  the  cost  and  availability  of  our  suppliers’  capital,  a  credit  rating  downgrade  or  deteriorating  financial
performance  of  the  Company  or  its  participating  subsidiaries,  or  other  changes  in  financial  markets  beyond  our  control.  We  do  not  expect  these  risks,  or
potential long-term growth of our Programs, to materially affect our overall financial condition, as we expect a significant portion of our payments to continue
to be made outside of the Programs. Accordingly, we do not believe the Programs have materially impacted our current period liquidity, and do not believe that
the Programs are reasonably likely to materially affect liquidity in the future.

Please refer to the Supplier Finance Programs section in Note 1 of the Consolidated Financial Statements for a rollforward of outstanding obligations under the
supplier finance programs.

Operating activities: In 2023, the Company generated $1,719 million of cash from operating activities compared to $1,760 million in 2022. The decrease in
cash  provided  by  operating  activities  was  primarily  due  to  reductions  in  payables  and  lower  earnings  in  2023,  which  were  partially  offset  by  inventory
reductions.

Investing  activities:  The  cash  used  for  investing  activities  in  2023  was  $356  million  compared  to  $623  million  in  2022.  This  decrease  was  due  to  lower
spending on acquisitions in 2023 compared to 2022 (see Note 7 for additional information). This was partially offset by higher capital spending and lower cash
from derivative settlements compared to the prior year.

Financing  activities:  Net  cash  used  for  financing  activities  in  2023  was  $877  million  compared  to  $974  million  in  2022. The  year-over-year  decrease  was
primarily due to lower purchases of treasury stock which were partially offset by higher 2023 dividend payments.

CRITICAL ACCOUNTING ESTIMATES

Our  discussion  and  analysis  of  our  financial  condition  and  results  of  operations  is  based  upon  our  Consolidated  Financial  Statements,  which  have  been
prepared in accordance with accounting principles generally accepted in the United States. The preparation of these financial statements requires management
to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of
the  financial  statements  and  the  reported  amounts  of  revenues  and  expenses  during  the  reporting  period.  On  an  ongoing  basis,  management  evaluates  its
estimates  and  judgments  related  to  these  assets,  liabilities,  revenues  and  expenses.  We  believe  these  estimates  to  be  reasonable  under  the  circumstances.
Management  bases  its  estimates  and  judgments  on  historical  experience,  expected  future  outcomes,  and  on  various  other  factors  that  are  believed  to  be
reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not
readily apparent from other sources. Actual results may differ from these estimates.

The Company believes that the following accounting estimates are critical to our financial results:

Tax Estimates. The determination of our tax provision is complex due to operations in several tax jurisdictions outside the United States. We apply a more-
likely-than-not recognition threshold for all tax uncertainties. Such uncertainties include any claims by the Internal Revenue Service for income taxes, interest,
and penalties attributable to audits of open tax years.

In addition, we record a valuation allowance to reduce our deferred tax assets to the amount that we believe is more likely than not to be realized. We estimate
future taxable income and the effect of tax planning strategies in our consideration of whether deferred tax assets will more likely than not be realized. In the
event we were to determine that we would not be able to realize all or part of our net deferred tax assets in the future, an adjustment to reduce the net deferred
tax assets would be charged to earnings in the period such determination was made. Conversely, if we were to determine that we would be able to realize our
net deferred tax assets in the future in excess of their currently recorded amount, an adjustment to increase the net deferred tax assets would be credited to
earnings in the period such determination was made.

Impairment of Assets. The Company exercises judgment in evaluating assets for impairment. Goodwill and other indefinite-lived intangible assets are tested for
impairment annually, or when circumstances arise which indicate there may be an impairment. Long-lived assets are tested for impairment when economic
conditions or management decisions indicate an impairment may exist. These tests require comparing recorded values to estimated fair values for the assets
under review.

The  Company  has  recorded  its  goodwill  and  conducted  testing  for  potential  goodwill  impairment  at  a  reporting  unit  level.  Our  reporting  units  represent  a
business  for  which  discrete  financial  information  is  available  and  segment  management  regularly  reviews  the  operating  results.  The  Company  has  three
reporting units: Roofing, Insulation and Composites.

2023 Annual Goodwill Impairment Assessment

Goodwill is an intangible asset that is not subject to amortization; however, annual tests are required to be performed to determine whether impairment exists.
Prior to performing the impairment testing process described in ASC 350-20, the guidance permits companies to assess qualitative factors to determine if it is
more likely than not that a reporting unit’s fair value is less than its carrying value. If, based on the review of the qualitative factors, we determine it is not more
likely than not that the fair value of a reporting unit is less than its carrying value, we would bypass the quantitative impairment test. Events and circumstances
we  consider  in  performing  the  qualitative  assessment  include  macro-economic  conditions,  market  and  industry  conditions,  internal  cost  factors,  and  the
operational stability and the overall financial performance of the reporting units. If it is more likely than not that a reporting unit’s fair value is less than or
close to its carrying value, then the quantitative impairment test must be performed to determine if impairment is required.

ITEM 7.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS (continued)

-40-

When it is determined necessary for the Company to perform the quantitative impairment process for goodwill, we estimate fair values using a discounted cash
flow approach from the perspective of a market participant. Significant assumptions used in the discounted cash flow approach are the revenue growth rates
and EBIT margins used in estimating discrete period cash flow forecasts of the reporting unit, the discount rate, the reporting unit tax rate and the long-term
revenue  growth  rate  and  EBIT  margin  used  in  estimating  the  terminal  business  value.  The  cash  flow  forecasts  of  the  reporting  unit  are  based  upon
management’s  long-term  view  of  our  markets  and  are  the  forecasts  that  are  used  by  senior  management  and  the  Board  of  Directors  to  evaluate  operating
performance. The discount rate utilized is management’s estimate of what the market’s weighted average cost of capital is for a company with a similar debt
rating and stock volatility, as measured by beta. The reporting unit specific tax rate is based on blended global historical rates. The terminal business value is
determined  by  applying  the  long-term  growth  rate  to  the  latest  year  for  which  a  forecast  exists.  As  part  of  our  goodwill  quantitative  testing  process,  the
Company evaluates whether there are reasonably likely changes to management’s estimates that would have a material impact on the results of the goodwill
impairment testing.

Our  annual  test  of  goodwill  for  impairment  was  conducted  as  of  October  1,  2023.  The  Company  elected  to  perform  the  qualitative  approach  on  all  of  its
reporting units: Roofing, Insulation and Composites. After evaluating and weighing all relevant events and circumstances, we concluded it is more likely than
not  that  the  fair  value  of  the  Roofing  and  Insulation  reporting  units  exceeds  their  respective  carrying  value  amounts.  Consequently,  we  did  not  perform  a
quantitative analysis for the Roofing and Insulation reporting units and determined that their goodwill was not impaired for 2023.
For the Composites reporting unit, based on the qualitative assessment we concluded that it is more likely than not that the fair value of the reporting unit was
less than its carrying amount. Therefore, we performed a quantitative analysis as described above. As a result of this test, we determined that no impairment
existed  for  the  reporting  unit.  Testing  indicated  that  the  business  enterprise  value  for  the  Composites  reporting  unit  exceeded  its  carrying  value  by
approximately 5%. There is uncertainty surrounding the macroeconomic factors that impact this reporting unit and a sustained downturn in these factors or a
change  in  the  long-term  revenue  growth  or  profitability  for  this  reporting  unit  could  increase  the  likelihood  of  a  future  impairment.  The  most  significant
assumptions  used  in  our  analysis  to  determine  the  fair  value  of  the  Composites  reporting  unit  are  the  discount  rate  and  long-term  growth  rate.  If  all  other
assumptions remain constant, a 50 basis point increase in the selected discount rate of 11% would decrease the fair value of the Composites reporting unit by
approximately 5%, and a 50 basis point decrease in the selected long-term growth rate of 2.5% would decrease the fair value of the Composites reporting unit
by approximately 4%.

Annual 2023 Indefinite-lived Intangible Asset Impairment Assessment

Fair values used in testing for potential impairment of our trademarks and trade names are calculated by applying an estimated market value royalty rate to the
forecasted  revenues  of  the  businesses  that  utilize  those  assets.  The  assumed  cash  flows  from  this  calculation  are  discounted  at  a  rate  based  on  a  market-
participant discount rate. Our annual test of indefinite-lived intangibles was conducted as of October 1, 2023. The fair value of each of our indefinite-lived
intangible assets exceeded the carrying value as of the date of our assessment.

ITEM 7.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS (continued)

-41-

Testing indicated that the fair values of a trade name used by our European building and technical insulation business and a trademark used on global cellular
glass insulation products exceeded their carrying values by 2% and 1%, respectively. A change in the estimated long-term revenue growth rate or increase in
the  discount  rate  assumption  could  increase  the  likelihood  of  a  future  impairment  for  these  assets.  For  the  trade  name  used  by  our  European  building  and
technical insulation business, if all other assumptions remain constant, a 50 basis point increase in the selected discount rate of 12.5% would decrease the fair
value by approximately 5%, and a 50 basis point decrease in the selected long-term growth rate of 2.0% would decrease the fair value by approximately 4%.
For the trademark used on global cellular glass insulation products, if all other assumptions remain constant, a 50 basis point increase in the selected discount
rate of 12.0% would decrease the fair value by approximately 5%, and a 50 basis point decrease in the selected long-term growth rate of 2.0% would decrease
the fair value by approximately 4%.

The carrying values of the European building and technical insulation trade name and the global cellular glass insulation trademark are $90 million and $80
million, respectively. Both of these assets are included within the Insulation segment.

The fair value of the remaining assets substantially exceeded their carrying value as of the date of our assessment.

Long-lived Asset Recoverability Assessment

Fair  values  for  long-lived  asset  testing  are  calculated  by  estimating  the  undiscounted  cash  flows  from  the  use  and  ultimate  disposition  of  the  asset  or  by
estimating the amount that a willing third party would pay. For impairment testing, long-lived assets are grouped at the lowest level for which identifiable cash
flows  are  largely  independent  of  the  cash  flows  of  other  groups  of  assets  and  liabilities.  The  Company  groups  long-lived  assets  based  on  manufacturing
facilities that produce similar products either globally or within a geographic region. Management tests asset groups for potential impairment whenever events
or  changes  in  circumstances  indicate  that  the  carrying  value  may  not  be  recoverable.  We  evaluated  and  concluded  that  there  are  not  any  reasonably  likely
changes to management’s estimates that would indicate that the carrying value of our long-lived assets is unrecoverable.

However, changes in management intentions, market conditions, operating performance and other similar circumstances could affect the assumptions used in
these impairment tests. Changes in the assumptions could result in impairment charges that could be material to our Consolidated Financial Statements in any
given period.

Product  Warranty:  The  Company  records  a  liability  for  warranty  obligations  at  the  date  the  related  products  are  sold.  Most  significant  are  the  standard
warranties on our roofing products. The standard warranties generally provide full coverage of labor and materials for a period of 5-10 years from the original
installation date and prorated materials for the remaining life of the roof.

Our  estimated  cost  of  our  standard  warranty  obligations  is  calculated  using  a  5-year  historical  average  of  claims  paid  for  each  major  product  category,  the
estimated future cost to manufacture the replacement shingles, and the estimated future cost for contractor labor, subject to the applicable warranty coverage,
for a 20-year period from the date of installation.

Additionally, the Company sells contractors extended warranties that extend coverage beyond our standard product warranty. The extended warranties revenue
is deferred and recognized over the related coverage period, ranging from 16 to 20 years.

Pensions and Other Postretirement Benefits. Accounting for pensions and other postretirement benefits involves estimating the cost of benefits to be provided
well  into  the  future  and  attributing  that  cost  over  the  time  period  each  employee  works.  To  accomplish  this,  extensive  use  is  made  of  assumptions  about
investment  returns,  discount  rates,  inflation,  mortality,  turnover,  and  medical  costs.  Changes  in  assumptions  used  could  result  in  a  material  impact  to  our
Consolidated Financial Statements in any given period.

Two key assumptions that could have a significant impact on the measurement of pension liabilities and pension expense are the discount rate and the expected
return on plan assets. For our largest plan, the United States plan, the discount rate used for the December 31, 2023 measurement date is based on a yield curve
approach where the expected future benefit payments are matched with a yield curve derived from certain AA-rated corporate bonds.

The result supported a discount rate of 5.00% at December 31, 2023 compared to 5.15% at December 31, 2022. A 25 basis point increase (decrease) in the
discount rate would (decrease) increase the December 31, 2023 projected benefit obligation for the United States pension plan by approximately $9 million. A
25 basis point increase (decrease) in the discount rate would (decrease) increase 2024 net periodic pension cost by less than $1 million.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS (continued)

-42-

The expected return on plan assets in the United States was derived by taking into consideration the target plan asset allocation, historical rates of return on
those assets, projected future asset class returns and net outperformance of the market by active investment managers and plan related and investment related
expenses paid from the plan trust. The Company uses the target plan asset allocation because we rebalance our portfolio to target on at least a quarterly basis.
An asset return model was used to develop an expected range of returns on plan investments over a 20-year period, with the expected rate of return selected
from a best estimate range within the total range of projected results. This process resulted in the selection of an expected return of 5.75% at the December 31,
2023  measurement  date,  which  is  used  to  determine  net  periodic  pension  cost  for  the  year  2024.  The  expected  return  selected  at  the  December  31,  2022
measurement date was 5.75%, which was used to determine the net periodic pension cost for the year 2023. A 25 basis point increase (decrease) in return on
plan assets assumption would result in a respective decrease (increase) of 2024 net periodic pension cost by approximately $1 million.

The  discount  rate  for  our  United  States  postretirement  plan  was  selected  using  the  same  method  as  described  for  the  pension  plan.  The  result  supported  a
discount  rate  of  4.90%  at  December  31,  2023  compared  to  5.10%  at  December  31,  2022. A  25  basis  point  increase  (decrease)  in  the  discount  rate  would
(decrease) increase the United States postretirement benefit obligation by approximately $2 million and (decrease) increase 2024 net periodic postretirement
benefit cost by less than $1 million.

The  methods  corresponding  to  those  described  above  are  used  to  determine  the  discount  rate  and  expected  return  on  assets  for  non-U.S.  pension  and
postretirement plans, to the extent applicable.

QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

-44-

The Company is exposed to the impact of changes in foreign currency exchange rates, interest rates and the prices of various commodities used in the normal
course of business. To mitigate some of the near-term volatility in our earnings and cash flows, the Company manages certain of our exposures through the use
of  financial  contracts,  contracts  for  physical  delivery  of  a  particular  commodity,  and  derivative  financial  instruments.  The  Company’s  objective  with  these
instruments is to reduce exposure to near-term fluctuations in earnings and cash flows. The Company’s policy enables the use of foreign currency, interest rate
and commodity derivative financial instruments only to the extent necessary to manage exposures as described above. The Company does not enter into such
transactions for trading purposes.

A discussion of the Company’s accounting policies for derivative financial instruments, as well as the Company’s exposure to market risk, is included in Notes
1 and 4 to the Consolidated Financial Statements. Please refer to Note 4 for details of the fair values of derivative financial instruments and their classification
on the Consolidated Balance Sheets.

For purposes of disclosing the market risk inherent in its derivative financial instruments the Company uses sensitivity analysis disclosures that express the
potential loss in fair values of market rate sensitive instruments resulting from changes in interest rates, foreign currency exchange rates, and commodity prices
that assume instantaneous, parallel shifts in exchange rates, interest rate yield curves, and commodity prices. The following analysis provides such quantitative
information regarding market risk. There are certain shortcomings inherent in the sensitivity analysis presented, primarily due to the assumption that exchange
rates change instantaneously and that interest rates change in a parallel fashion. In addition, the analyses are unable to reflect the complex market reactions that
normally would arise from the market shifts modeled.

Foreign Exchange Rate Risk

The Company has transactional foreign currency exposures related to buying, selling, and financing in currencies other than the local currencies in which it
operates.  The  Company  enters  into  various  forward  contracts,  which  change  in  value  as  foreign  currency  exchange  rates  change,  to  preserve  the  carrying
amount  of  foreign  currency-denominated  assets,  liabilities,  commitments,  and  certain  anticipated  foreign  currency  transactions.  Exposures  are  related  to  the
United  States  Dollar  primarily  relative  to  the  Brazilian  Real,  Indian  Rupee,  Chinese Yuan,  Hong  Kong  Dollar,  South  Korean Won,  and  the  European  Euro
exchange rates. Also, there are additional exposures related to the European Euro primarily versus the Polish Złoty, British Pound Sterling, and the U.S. Dollar.
These  transactional  risks  are  mitigated  through  the  use  of  derivative  financial  instruments  and  balancing  of  cash  deposits  and  loans.  The  net  fair  value  of
derivative  financial  instruments  used  to  limit  exposure  to  foreign  currency  risk  was  a  liability  of  less  than  $1  million  and  a  liability  of  $1  million  as  of
December  31,  2023  and  2022,  respectively. As  of  December  31,  2023,  the  potential  change  in  fair  value  for  such  financial  instruments  from  an  increase
(decrease) of 10% in the quoted foreign currency exchange rates would be a (decrease) increase of approximately $4 million and $3 million, respectively. As of
December  31,  2022,  the  potential  change  in  fair  value  for  such  financial  instruments  from  an  increase  (decrease)  of  10%  in  the  quoted  foreign  currency
exchange rates would be a (decrease) increase of approximately $7 million and $5 million, respectively.

We  have  translation  exposure  resulting  from  translating  the  financial  statements  of  foreign  subsidiaries  into  United  States  Dollars.  Our  most  significant
translation exposures are the Canadian Dollar, Chinese Yuan, European Euro, Indian Rupee, and Polish Złoty in relation to the United States Dollar.

Interest Rate Risk

The Company is subject to market risk from exposure to changes in interest rates due to its financing, investing, and cash management activities. The Company
has a Senior Revolving Credit Facility, Receivables Securitization Facility, other floating rate debt and cash and cash equivalents which are exposed to floating
interest rates and may impact cash flow. As of December 31, 2023, the Company had no borrowings on its Senior Revolving Credit Facility or Receivables
Securitization  Facility,  with  the  balance  of  other  floating-rate  debt  of  $1  million. As  of  December  31,  2022,  the  Company  had  no  borrowings  on  its  Senior
Revolving Credit Facility or Receivables Securitization Facility, with the balance of other floating rate debt of $1 million. Cash and cash equivalents were $1.6
billion and $1.1 billion at December 31, 2023 and 2022, respectively. Based on the year-end outstanding balances on floating rate debt, a one percentage point
increase (decrease) in interest rates at December 31, 2023 and 2022 would increase (decrease) our annual net interest expense by less than $1 million for each
year.

The Company is exposed to changes in prices of commodities used in its operations, primarily associated with energy, such as natural gas, and raw materials,
such as asphalt and polystyrene. The Company enters into cash-settled natural gas swap contracts in certain markets to protect against changes in natural gas
prices that mature within 15 months; however, no financial instruments are currently used to protect against changes in raw material costs. At December 31,
2023 and 2022, the net fair value of such swap contracts was a liability of $15 million and a liability of $30 million, respectively. The potential change in fair
value at December 31, 2023 and 2022 resulting from an increase (decrease) of 10% in the underlying commodity prices would be an increase (decrease) of $4
million  for  2023  and  an  increase  (decrease)  of  $8  million  for  2022.  This  amount  excludes  the  offsetting  impact  of  the  price  risk  inherent  in  the  physical
purchase of the underlying commodities.

Report of Independent Registered Public Accounting Firm

To the Board of Directors and Stockholders of Owens Corning

Opinions on the Financial Statements and Internal Control over Financial Reporting

We have audited the accompanying consolidated balance sheets of Owens Corning and its subsidiaries (the “Company”) as of December 31, 2023 and 2022,
and the related consolidated statements of earnings, of comprehensive earnings, of stockholders’ equity and of cash flows for each of the three years in the
period ended December 31, 2023, including the related notes and schedule of valuation and qualifying accounts and reserves for each of the three years in the
period  ended  December  31,  2023  appearing  on  page  117  (collectively  referred  to  as  the  “consolidated  financial  statements”).  We  also  have  audited  the
Company's internal control over financial reporting as of December 31, 2023, 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  consolidated  financial  statements  referred  to  above  present  fairly,  in  all  material  respects,  the  financial  position  of  the  Company  as  of
December  31,  2023  and  2022,  and  the  results  of  its  operations  and  its  cash  flows  for  each  of  the  three  years  in  the  period  ended  December  31,  2023  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, 2023, based on criteria established in Internal Control - Integrated Framework
(2013) issued by the COSO.

Basis for Opinions

The Company's management is responsible for these consolidated 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  Report  on  Internal  Control
Over Financial Reporting. Our responsibility is to express opinions on the Company’s consolidated financial statements and 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 consolidated 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 consolidated financial statements included performing procedures to assess the risks of material misstatement of the consolidated financial
statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence
regarding  the  amounts  and  disclosures  in  the  consolidated  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 consolidated 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 (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect
the  transactions  and  dispositions  of  the  assets  of  the  company;  (ii)  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  (iii)  provide  reasonable  assurance  regarding  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.

-60-

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 matter communicated below is a matter arising from the current period audit of the consolidated financial statements that was communicated
or required to be communicated to the audit committee and that (i) relates to accounts or disclosures that are material to the consolidated financial statements
and  (ii)  involved  our  especially  challenging,  subjective,  or  complex  judgments.  The  communication  of  critical  audit  matters  does  not  alter  in  any  way  our
opinion  on  the  consolidated  financial  statements,  taken  as  a  whole,  and  we  are  not,  by  communicating  the  critical  audit  matter  below,  providing  a  separate
opinion on the critical audit matter or on the accounts or disclosures to which it relates.

Goodwill Impairment Assessment – Composites Reporting Unit

As described in Notes 1 and 5 to the consolidated financial statements, the Company’s consolidated goodwill balance was $1,392 million as of December 31,
2023, and the goodwill associated with the Composites reporting unit was $425 million. Management tests goodwill for impairment as of October 1 each year,
or more frequently should circumstances change or events occur that would more likely than not reduce the fair value of a reporting unit below its carrying
amount. Management estimates fair value using a discounted cash flow approach from the perspective of a market participant. Significant assumptions used in
the discounted cash flow approach are revenue growth rates and earnings before interest and taxes (“EBIT”) margins used in estimating the discrete period cash
flow forecasts of the reporting unit, the discount rate, and the long-term revenue growth rate and EBIT margin used in estimating the terminal business value.

The principal considerations for our determination that performing procedures relating to the goodwill impairment assessment of the Composites reporting unit
is a critical audit matter are (i) the significant judgment by management when developing the fair value estimate of the Composites reporting unit; (ii) a high
degree  of  auditor  judgment,  subjectivity  and  effort  in  performing  procedures  and  evaluating  management’s  significant  assumptions  related  to  the  revenue
growth rates and EBIT margins used in estimating the discrete period cash flow forecasts of the reporting unit, the discount rate, and the long-term revenue
growth rate and EBIT margin used in estimating the terminal business value; and (iii) the audit effort involved the use of professionals with specialized skill
and knowledge.

Addressing  the  matter  involved  performing  procedures  and  evaluating  audit  evidence  in  connection  with  forming  our  overall  opinion  on  the  consolidated
financial  statements.  These  procedures  included  testing  the  effectiveness  of  controls  relating  to  management’s  goodwill  impairment  assessment,  including
controls over the valuation of the Composites reporting unit. These procedures also included, among others (i) testing management’s process for developing the
fair value estimate; (ii) evaluating the appropriateness of the discounted cash flow approach used by management; (iii) testing the completeness and accuracy
of  underlying  data  used  in  the  discounted  cash  flow  approach;  and  (iv)  evaluating  the  reasonableness  of  the  significant  assumptions  used  by  management
related to the revenue growth rates and EBIT margins used in estimating the discrete period cash flow forecasts, the discount rate, and the long-term revenue
growth rate and EBIT margin used in estimating the terminal business value. Evaluating management’s assumptions related to the revenue growth rates and
EBIT margins used in estimating the discrete period cash flow forecasts and EBIT margin used in estimating the terminal business value involved evaluating
whether the assumptions used by management were reasonable considering (i) the current and past performance of the reporting unit; (ii) the consistency with
external  market  and  industry  data;  and  (iii)  whether  the  assumptions  were  consistent  with  evidence  obtained  in  other  areas  of  the  audit.  Professionals  with
specialized  skill  and  knowledge  were  used  to  assist  in  evaluating  (i)  the  appropriateness  of  management’s  discounted  cash  flow  approach  and  (ii)  the
reasonableness of the discount rate assumption and the long-term revenue growth rate assumption.

OWENS CORNING AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1.    BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Description of Business

Owens  Corning,  a  Delaware  corporation,  is  a  global  building  and  construction  materials  leader  committed  to  building  a  sustainable  future  through  material
innovation. The Company operates within three segments: Roofing, Insulation and Composites. Through these lines of business, Owens Corning manufactures
and sells products worldwide. The Company maintains leading market positions in many of its major product categories.

General

On February 1, 2024, the Board of Directors declared a quarterly dividend of $0.60 per common share payable on April 4, 2024 to shareholders of record as of
March 4, 2024.

Basis of Presentation

Unless the context requires otherwise, the terms “Owens Corning,” “Company,” “we” and “our” in these notes refer to Owens Corning and its subsidiaries.

The accompanying Consolidated Financial Statements have been prepared in accordance with accounting principles generally accepted in the United States.

Principles of Consolidation

The  Consolidated  Financial  Statements  of  the  Company  include  the  accounts  of  majority-owned  subsidiaries.  Intercompany  accounts  and  transactions  are
eliminated.

Reclassifications

Certain  reclassifications  have  been  made  to  the  2022  and  2021  Consolidated  Financial  Statements  and  Notes  to  the  Consolidated  Financial  Statements  to
conform to the classifications used in 2023.

Use of Estimates and Assumptions

The  preparation  of  financial  statements  in  conformity  with  accounting  principles  generally  accepted  in  the  United  States  requires  management  to  make
estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ materially from those estimates.

Revenue Recognition

We recognize revenue as the amount of consideration that we expect to receive in exchange for transferring promised goods or services to customers. We do
not  adjust  the  transaction  price  for  the  effects  of  a  significant  financing  component,  as  the  time  period  between  control  transfer  of  goods  and  services  and
expected payment is one year or less. At the time of sale, we estimate provisions for different forms of variable consideration (discounts, rebates, returns and
other refund liabilities) based on historical experience, current conditions and contractual obligations, as applicable. The estimated transaction price is typically
not  subject  to  significant  reversals.  We  adjust  these  estimates  when  the  most  likely  amount  of  consideration  we  expect  to  receive  changes,  although  these
changes are typically minor. Sales, value-added and other similar taxes that we collect are excluded from revenue.

Many of our customer volume commitments are short-term and our performance obligations are generally limited to single purchase orders. Substantially all of
our revenue is recognized at a point-in-time when control of goods transfers to the customer. Control transfer typically occurs when goods are shipped from our
facilities or at other predetermined control transfer points (for instance, destination terms or consignment arrangements).

Revenue Recognition (continued)

We typically do not satisfy performance obligations without obtaining an unconditional right to payment from customers and, therefore, do not carry contract
asset balances on the Consolidated Balance Sheets. Contract liability balances are recorded separately from receivables on the Consolidated Balance Sheets in
either Total current liabilities or Other liabilities, depending on the timing of performance obligation satisfaction.

We sell separately-priced warranties that extend certain product and workmanship coverages beyond our standard product warranty, which is described in Note
11.  The  up-front  consideration  on  extended  warranty  contracts  is  deferred  and  recognized  as  revenue  over  time,  based  on  the  respective  coverage  period,
ranging  from  16  to  20  years.  On  an  annual  basis,  we  expect  to  recognize  approximately  $7  million  of  revenue  associated  with  these  extended  warranty
contracts.  Additionally,  in  certain  limited  cases,  we  receive  consideration  before  goods  or  services  are  transferred  to  the  customer.  These  customer  down
payments and deposits are deferred, and typically recognized as revenue in the following quarters when we satisfy the related performance obligations.

As  of  December  31,  2023,  our  contract  liability  balances  (for  extended  warranties,  down  payments  and  deposits,  collectively)  totaled  $101  million. As  of
December 31, 2022, our contract liability balances totaled $89 million, of which $18 million was recognized as revenue throughout 2023. As of December 31,
2021,  our  contract  liability  balances  (for  extended  warranties,  down  payments  and  deposits,  collectively)  totaled  $76  million,  of  which  $17  million  was
recognized  as  revenue  throughout  2022. As  of  December  31,  2020,  our  contract  liability  balances  (for  extended  warranties,  down  payments  and  deposits,
collectively) totaled $66 million, of which $17 million was recognized as revenue throughout 2021.
As a practical expedient, we recognize incremental costs of obtaining a contract, if any, as an expense when incurred if the amortization period of the asset
would have been one year or less. We do not have any costs to obtain or fulfill a contract that are capitalized under Accounting Standards Codification (“ASC”)
606.

Cost of Sales

Cost  of  sales  includes  material,  labor,  energy  and  manufacturing  overhead  costs,  including  depreciation  and  amortization  expense  associated  with  the
manufacture and distribution of the Company’s products. Provisions for warranties are provided in the same period that the related sales are recorded and are
based on historical experience, current conditions and contractual obligations, as applicable. Distribution costs include inbound freight costs; purchasing and
receiving costs; inspection costs; warehousing costs; shipping and handling costs, which include costs incurred relating to preparing, packaging, and shipping
products to customers; and other costs of the Company’s distribution network. We account for shipping and handling activities that occur after control of the
related good transfers as fulfillment activities instead of performance obligations. All shipping and handling costs billed to the customer are included as net
sales in the Consolidated Statements of Earnings.

Marketing and Advertising Expenses

Marketing and advertising expenses are included in Marketing and administrative expenses. These costs include advertising and marketing communications,
which are expensed the first time the advertisement takes place. Marketing and advertising expenses for the years ended December 31, 2023, 2022 and 2021
were $134 million, $125 million and $110 million, respectively.

Science and Technology Expenses

The Company incurs certain expenses related to science and technology. These expenses include salaries, building and equipment costs, utilities, administrative
expenses, materials and supplies associated with the improvement and development of the Company’s products and manufacturing processes. These costs are
expensed as incurred.

Earnings per Share

Basic earnings per share are computed using the weighted-average number of common shares outstanding during the period. Diluted earnings per share reflect
the dilutive effect of common equivalent shares and increased shares that would result from the conversion of equity securities. The effects of anti-dilution are
not presented.

Cash, Cash Equivalents and Restricted Cash

The  Company  defines  cash  and  cash  equivalents  as  cash  and  time  deposits  with  maturities  of  three  months  or  less  when  purchased.  On  the  Consolidated
Statements  of  Cash  Flows,  the  total  of  Cash,  cash  equivalents  and  restricted  cash  includes  restricted  cash  of  $8  million,  $8  million  and  $7  million  as  of
December  31,  2023,  2022  and  2021,  respectively.  Restricted  cash  primarily  represents  amounts  received  from  a  counterparty  related  to  its  performance
assurance on an executory contract, and is included in Other current assets on the Consolidated Balance Sheets. These amounts are contractually required to be
set aside, and the counterparty can exchange the cash for another form of performance assurance at its discretion.

Accounts Receivable

Trade  accounts  receivable  are  recorded  at  the  invoiced  amount  and  do  not  bear  interest.  Consistent  with  the  requirements  of  ASU  2016-13,  “Financial
Instruments - Credit Losses (Topic 236),” the allowance for credit losses is based on the Company’s assessment of the expected losses of customer accounts.
The Company regularly reviews the allowance by considering factors such as historical experience, credit quality, the age of the accounts receivable balances,
and  current  economic  conditions  that  may  affect  a  customer’s  ability  to  pay. Account  balances  are  charged  off  against  the  allowance  when  the  Company
believes it is probable the receivable will not be recovered.

Inventory Valuation

Inventory costs include material, labor, and manufacturing overhead costs, including depreciation and amortization expense associated with the manufacture
and  distribution  of  the  Company’s  products.  Inventories  are  stated  at  lower  of  cost  or  net  realizable  value  and  expense  estimates  are  made  for  excess  and
obsolete inventories. Cost is determined by the first-in, first-out (“FIFO”) method.

Investments in Affiliates

The  Company  accounts  for  investments  in  affiliates  of  20%  to  50%  ownership  when  the  Company  does  not  have  a  controlling  financial  interest  using  the
equity  method  under  which  the  Company’s  share  of  earnings  and  losses  of  the  affiliate  is  reflected  in  earnings,  and  dividends  are  credited  against  the
investment  in  affiliate  when  declared.  Investments  in  affiliates  are  recorded  in  Other  non-current  assets  on  the  Consolidated  Balance  Sheets,  and  as  of
December 31, 2023 and 2022, the total value of investments was $29 million and $27 million, respectively.

Goodwill and Other Intangible Assets

Goodwill  assets  are  not  amortized  but  are  tested  for  impairment  on  at  least  an  annual  basis.  The  Company  has  the  option  to  use  a  qualitative  approach  to
determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying value as a basis for determining whether it is necessary
to perform a quantitative test. In the current year, as part of the annual assessment, the Company used both a qualitative and quantitative approach to determine
whether the fair value of a reporting unit was less than its carrying amount.

Events and circumstances we consider in performing the qualitative assessment include macro-economic conditions, market and industry conditions, internal
cost  factors,  and  the  operational  stability  and  the  overall  financial  performance  of  the  reporting  units. When  it  is  determined  necessary  for  the  Company  to
perform  the  quantitative  testing  process  for  goodwill,  the  Company  estimates  fair  values  using  a  discounted  cash  flow  approach  from  the  perspective  of  a
market  participant.  Significant  assumptions  used  in  the  discounted  cash  flow  approach  are  revenue  growth  rates  and  earnings  before  interest  and  taxes
(“EBIT”) margins used in estimating discrete period cash flow forecasts of the reporting unit, the discount rate, and the long-term revenue growth rate and
EBIT margin used in estimating the terminal business value. The cash flow forecasts of the reporting units are based upon management’s long-term view of our
markets and are the forecasts that are used by senior management and the Board of Directors to evaluate operating performance. The discount rate utilized is
management’s estimate of what the market’s weighted average cost of capital is for a company with a similar debt rating and stock volatility, as measured by
beta. The terminal business value is determined by applying the long-term growth rate to the latest year for which a forecast exists. As part of our goodwill
quantitative testing process, we would evaluate whether there are reasonably likely changes to management’s estimates that would have a material impact on
the results of the goodwill impairment testing.

Goodwill and Other Intangible Assets (continued)

Other indefinite-lived intangible assets are not amortized but are tested for impairment on at least an annual basis or when determined to have a finite useful
life. Substantially all of the indefinite-lived intangible assets are in trademarks and trade names. The Company uses the royalty relief approach to determine
whether it is more likely than not that the fair value of these assets is less than its carrying amount. This review is performed annually, or when circumstances
arise which indicate there may be impairment. When applying the royalty relief approach, the Company performs a discounted cash flow analysis based on the
value derived from owning these trademarks and trade names and being relieved from paying royalty to third parties. Significant assumptions used include the
discrete period revenue growth rates, long-term revenue growth rate, royalty rates, discount rates and terminal value.

The inputs for the goodwill and indefinite-lived intangible tests are considered Level 3 inputs under the fair value hierarchy as they are the Company’s own
data,  and  are  unobservable  in  the  marketplace.  Indefinite-lived  intangible  assets  purchased  through  acquisitions  are  generally  tested  qualitatively  for
impairment in the first year following the acquisition before transitioning to the standard methodology described herein in subsequent years.

Please refer to Note 5 for additional disclosures related to Goodwill and Other Intangible Assets.

Emissions Rights

The Company is allotted carbon emission credit allowances (“emissions rights”) from several of the governments under which it operates. These emissions
rights are recorded at market value as of the date of issuance and are classified as Intangible assets on the Consolidated Balance Sheets. When the Company
emits more than the allotted amounts, additional emissions rights must be purchased.

Properties and Depreciation

Property, plant and equipment are stated at cost and depreciated over their estimated useful lives using the straight-line method. When assets are disposed or
otherwise retired, Property, plant and equipment accounts are relieved of the cost and related accumulated depreciation and any gain or loss is included in the
Consolidated Statements of Earnings.

Precious  metals  used  in  our  production  tooling  are  included  in  property,  plant  and  equipment  and  are  depleted  as  they  are  consumed  during  the  production
process. Depletion typically represents an annual expense of 2% of the outstanding value and is recorded in Cost of sales on the Consolidated Statements of
Earnings.

The Company evaluates tangible and intangible long-lived assets for impairment when triggering events have occurred. This requires significant assumptions
including projected cash flows, projected income tax rate and terminal business value. These inputs are considered Level 3 inputs under the fair value hierarchy
as they are the Company’s own data, and are unobservable in the marketplace. Changes in management intentions, market conditions or operating performance
could indicate that impairment charges might be necessary that could be material to the Company’s Consolidated Financial Statements in any given period.
Please refer to Note 5 for additional detail on impairment charges recorded in 2022.

Supplier Finance Programs

We review supplier terms and conditions on an ongoing basis, and have negotiated payment terms extensions in recent years in connection with our efforts to
reduce  working  capital  and  improve  cash  flow.  Separate  from  those  terms  extension  actions,  certain  of  our  subsidiaries  have  entered  into  paying  agency
agreements with third-party administrators. These voluntary supply chain finance programs (collectively, the “Programs”) generally give participating suppliers
the ability to sell, or otherwise pledge as collateral, their receivables from the Company to the participating financial institutions, at the sole discretion of both
the suppliers and financial institutions. The Company is not a party to the arrangements between the suppliers and the financial institutions. The Company’s
obligations to its suppliers, including amounts due and scheduled payment dates, are not impacted by the suppliers’ decisions to sell, or otherwise pledge as
collateral, amounts under these arrangements. The Company's payment terms to the financial institutions, including the timing and amount of payments, are
based on the original supplier invoices. One of our programs includes a parent guarantee to the participating financial institution for a certain U.S. subsidiary
that, at the time of the respective program’s inception in 2015, was a guarantor subsidiary of the Company’s Credit Agreement. The obligations are presented as
Accounts payable within Total current liabilities on the Consolidated Balance Sheets and all activity related to the obligations is presented within operating
activities on the Consolidated Statements of Cash Flow.

The Company's outstanding obligations under the programs for the twelve months ended December 31, 2023 and 2022 are as follows (in millions):

Confirmed obligations outstanding at the beginning of the year
Invoices confirmed during the year
Confirmed invoices paid during the year

The Company recognizes current tax liabilities and assets for the estimated taxes payable or refundable on the tax returns for the current year. Deferred tax
balances reflect the impact of temporary differences between the carrying amount of assets and liabilities and their tax basis. Amounts are stated at enacted tax
rates expected to be in effect when taxes are actually paid or recovered. In addition, realization of certain deferred tax assets is dependent upon our ability to
generate future taxable income. The Company records a valuation allowance to reduce its deferred tax assets to the amount that it believes is more likely than
not to be realized. In addition, the Company estimates tax reserves to cover potential taxing authority claims for income taxes and interest attributable to audits
of open tax years. Please refer to Note 20 for additional disclosures related to Income Taxes.

Taxes Collected from Customers and Remitted to Government Authorities and Taxes Paid to Vendors

Taxes  are  assessed  by  various  governmental  authorities  at  different  rates  on  many  different  types  of  transactions. The  Company  charges  sales  tax  or  value-
added  tax  (“VAT”)  on  sales  to  customers  where  applicable,  as  well  as  captures  and  claims  back  all  available VAT  that  has  been  paid  on  purchases. VAT  is
recorded in separate payable or receivable accounts and does not affect Net Sales or Cost of Sales line items on the Consolidated Statement of Earnings. VAT
receivable  is  recorded  as  a  percentage  of  qualifying  purchases  at  the  time  the  vendor  invoice  is  processed.  VAT  payable  is  recorded  as  a  percentage  of
qualifying sales at the time an Owens Corning sale to a customer subject to VAT occurs. Amounts are paid to the taxing authority according to the method and
collection prescribed by local regulations. Where applicable, VAT payable is netted against VAT receivable. The Company also pays sales tax to vendors who
include a tax, required by government regulations, to the purchase price charged to the Company.

Pension and Other Postretirement Benefits

Accounting for pensions and other postretirement benefits involves estimating the cost of benefits to be provided well into the future and attributing that cost
over  the  time  period  each  employee  works.  To  accomplish  this,  extensive  use  is  made  of  assumptions  about  investment  returns,  discount  rates,  inflation,
mortality, turnover and medical costs. Please refer to Notes 14 and 15 for additional disclosures related to Pension Plans and Other Postretirement Benefits,
respectively.

Derivative Financial Instruments

The Company recognizes all derivative instruments as either assets or liabilities at fair value on the balance sheet. Please refer to Note 4 for further disclosure
on derivatives.

The Company performs an analysis for effectiveness of its derivatives designated as hedging instruments at the end of each quarter based on the terms of the
contracts and the underlying items being hedged. The change in the fair value of cash flow hedges is deferred in Accumulated other comprehensive income
(deficit) (“AOCI”) and is subsequently recognized in Cost of sales (for commodity and foreign currency cash flow hedges) on the Consolidated Statements of
Earnings in order to mirror the location of the hedged items impacting earnings. Cash settlements for commodity and foreign currency hedges qualifying as
cash flow hedges are included in Operating activities in the Consolidated Statements of Cash Flows.

The  Company  has  translation  exposure  resulting  from  translating  the  financial  statements  of  foreign  subsidiaries  into  U.S.  Dollars,  which  is  recognized  in
Currency  translation  adjustment  (a  component  of AOCI).  The  Company  uses  cross-currency  forward  contracts  to  hedge  portions  of  the  net  investment  in
foreign  subsidiaries  against  fluctuations  in  foreign  exchange  rates.  The  changes  in  fair  values  of  these  derivative  instruments  are  recognized  in  Currency
translation adjustment (a component of AOCI), with recognition of the excluded components amortized to Interest expense, net on the Consolidated Statements
of Earnings. Cash settlements for derivatives qualifying as net investment hedges are included in Investing activities in the Consolidated Statements of Cash
Flows.

The Company uses forward currency exchange contracts to manage existing exposures to foreign exchange rate risks related to assets and liabilities recorded
on the Consolidated Balance Sheets. Gains and losses resulting from the changes in fair value of these instruments are recorded in Other expense (income), net
on the Consolidated Statements of Earnings, and are substantially offset by net revaluation impacts on foreign currency denominated balance sheet exposures
(which are also recorded in Other expense (income), net). Cash settlements for non-designated derivatives are included in the Consolidated Statements of Cash
Flows in the category that is consistent with the nature of the derivative instrument, which is generally the same category as the underlying item being hedged.

Fair Value Measurements

The  carrying  value  of  cash  and  cash  equivalents,  accounts  receivable  and  short-term  debt  approximate  fair  value  because  of  the  short-term  maturity  of  the
instruments.

Please refer to Notes 4, 13, 14 and 15 for fair value disclosures of derivative financial instruments, long-term debt, pension plans and postemployment and
postretirement benefits other than pensions.

Foreign Currency

The functional currency of the Company’s subsidiaries is generally the applicable local currency. Assets and liabilities of foreign subsidiaries are translated into
United States Dollars at the period-end rate of exchange, and their Statements of Earnings (Loss) and Statements of Cash Flows are converted at the monthly
average  rate.  The  resulting  translation  adjustment  is  included  in AOCI  in  the  Consolidated  Balance  Sheets  and  Consolidated  Statements  of  Stockholders’
Equity. Transaction gains and losses that arise from exchange rate fluctuations on transactions denominated in a currency other than the functional currency are
recorded in Other expense (income), net in the Consolidated Statements of Earnings as incurred. As discussed in the Derivative Financial Instruments section
above,  the  Company  uses  non-designated  foreign  currency  derivative  financial  instruments  to  mitigate  this  risk.  The  Company  recorded  foreign  currency
transactional (losses)/gains, net of associated derivative activity, of $(2) million, $(4) million and $1 million during the years ended December 31, 2023, 2022,
and 2021, respectively. Please refer to Note 4 for additional disclosures related to non-designated derivatives.

Related Party Transactions

In the first quarter of 2021, a related party relationship was established as a result of a member of the Company’s Board of Directors being named an executive
officer of one of the Company’s preexisting suppliers. The related party transactions with this supplier consist of the purchase of raw materials. Purchases from
the related party supplier were $92 million for the year ended December 31, 2023. As of December 31, 2023, amounts due to the related party supplier were
$5  million.  Purchases  from  the  related  party  supplier  were  $129  million  and  $87  million  for  the  years  ended  December  31,  2022  and  December  31,  2021,
respectively. As of December 31, 2022 and December 31, 2021, amounts due to the related party supplier were $3 million and $1 million, respectively.

Failed Sale-Leaseback - Fort Smith, Arkansas Municipal Tax Incentive

In the fourth quarter of 2023, the Company signed a municipal tax incentive agreement, as part of which, the Company sold its Fort Smith, Arkansas plant and
equipment (together, the “facility”) to the municipality of Fort Smith for cash of $165 million. The Company then, on the same day, entered into an agreement
to lease the facility from the municipality of Fort Smith over ten years for a total lease liability of $165 million and immediately purchased ten-year municipal
bonds at 6.7% interest issued by the municipality of Fort Smith with cash of $165 million. In the Consolidated Statements of Cash Flows, the cash proceeds
from the sale of the facility and the cash used for the bond purchase are presented on a net basis within the Net cash flows used by investing activities.

The monthly lease payments under the financing lease obligation and the semi-annual bond coupon payments associated with the bond investment are legally
offset and, as such, the offset lease obligation and bond investment amounts are presented on a net basis on the Consolidated Balance Sheets. There will be no
cash payments made by either party over the ten-year period. At the termination of the lease agreement, a non-cash exchange will occur where the municipality
will call the bond and return title of the facility to the Company.

The  transaction  did  not  qualify  for  sale-leaseback  treatment  under ASC  842  and,  therefore,  the  plant’s  net  book  value,  as  well  as  the  net  book  value  of  the
equipment sold, remains in Property, plant and equipment, net on the Consolidated Balance Sheets. Depreciation expense on the assets sold remains within
Cost of Sales on the Consolidated Statements of Earnings.

2.    SEGMENT INFORMATION

The  Company  has  three  reportable  segments:  Roofing,  Insulation  and  Composites.  Accounting  policies  for  the  segments  are  the  same  as  those  for  the
Company. The Company’s three reportable segments are defined as follows:

Roofing – Within our Roofing segment, the Company manufactures and sells residential roofing shingles, oxidized asphalt materials, and roofing components
used in residential and commercial construction and specialty applications.

Insulation – Within our Insulation segment, the Company manufactures and sells thermal and acoustical batts, loosefill insulation, spray foam insulation, foam
sheathing and accessories. It also manufactures and sells glass fiber pipe insulation, energy efficient flexible duct media, bonded and granulated stone wool
insulation, cellular glass insulation, and foam insulation used in above- and below-grade construction applications.

Composites – Within our Composites segment, the Company manufactures, fabricates and sells glass reinforcements in the form of fiber. Glass reinforcement
materials are also used by the Composites segment to manufacture and sell high value applications in the form of non-wovens, fabrics and composite lumber.

NET SALES

The following tables show a disaggregation of our net sales by segment and geographic region (in millions). Corporate eliminations (shown below) largely
reflect intercompany sales from Composites to Roofing. External customer sales are attributed to geographic region based upon the location from which the
product is sold to the external customer.

(11%) of consolidated sales in 2023 and 2021, respectively. No individual customers accounted for 10% or more of consolidated sales in 2022.

In the United States, sales are primarily related to the residential housing market and commercial and industrial applications. Residential market demand is
driven by housing starts and repair and remodeling activity (influenced by existing home sales, seasonal home improvement and damage from major storms).
Significant  portions  of  our  residential  products  across  our  three  reportable  segments  are  used  interchangeably  in  both  new  construction  and  repair  and
remodeling, and our customers typically distribute (or use) the products for both applications. U.S. commercial and industrial revenues are largely driven by
U.S. industrial production growth, commercial construction activity and overall economic conditions in the U.S.

Outside of the United States (Europe, Asia-Pacific and Rest of world), sales are primarily related to commercial and industrial applications and, to a lesser
extent,  residential  applications  in  certain  countries.  Throughout  the  international  regions,  demand  is  primarily  driven  by  industrial  production  growth,
commercial construction activity and overall economic conditions in each respective geographical region.

Earnings before interest and taxes (EBIT) by segment consists of net sales less related costs and expenses and are presented on a basis that is used internally for
evaluating segment performance. Certain items, such as general corporate expenses or income and certain other expense or income items, are excluded from
the  internal  evaluation  of  segment  performance.  Accordingly,  these  items  are  not  reflected  in  EBIT  for  our  reportable  segments  and  are  included  within

The Company is exposed to, among other risks, the impact of changes in commodity prices, foreign currency exchange rates, and interest rates in the normal
course of business. The Company’s risk management program is designed to manage the exposure and volatility arising from these risks, and utilizes derivative
financial  instruments  to  offset  a  portion  of  these  risks. The  Company  uses  derivative  financial  instruments  only  to  the  extent  necessary  to  hedge  identified
business risks, and does not enter into such transactions for trading purposes.

The Company generally does not require collateral or other security with counterparties to these financial instruments and is therefore subject to credit risk in
the event of nonperformance; however, the Company monitors credit risk and currently does not anticipate nonperformance by other parties. Contracts with
counterparties generally contain right of offset provisions. These provisions effectively reduce the Company’s exposure to credit risk in situations where the
Company  has  gain  and  loss  positions  outstanding  with  a  single  counterparty.  It  is  the  Company’s  policy  to  offset  on  the  Consolidated  Balance  Sheets  the
amounts recognized for derivative instruments with any cash collateral arising from derivative instruments executed with the same counterparty under a master
netting agreement. As of December 31, 2023 and 2022, the Company did not have any amounts on deposit with any of its counterparties, nor did any of its
counterparties have any amounts on deposit with the Company.

Derivative Fair Values

Our derivatives consist of natural gas forward swaps, cross-currency swaps, foreign exchange forward contracts and U.S. treasury rate lock agreements, all of
which  are  over-the-counter  and  not  traded  through  an  exchange.  The  Company  uses  widely  accepted  valuation  tools  to  determine  fair  value,  such  as
discounting  cash  flows  to  calculate  a  present  value  for  the  derivatives.  The  models  use  Level  2  inputs,  which  are  observable  market-based  inputs  or
unobservable inputs that are corroborated by market data. Examples include forward curves and other commonly quoted observable transactions and prices.
The fair value of our derivatives and hedging instruments are all classified as Level 2 investments within the three-tier hierarchy.

The Company uses a combination of derivative financial instruments, which qualify as cash flow hedges, and physical contracts to manage forecasted exposure
to electricity and natural gas prices. As of December 31, 2023, the notional amounts of these natural gas forward swaps were 7 million MMBTu (or MMBTu
equivalent  based  on  U.S.  and  European  indices),  compared  with  the  notional  amounts  of  8  million  MMBTu  at  December  31,  2022.          The  Company  has
designated these natural gas forward swaps as cash flow hedges, with the last hedge maturing no later than March 2025. A net unrecognized loss of $15 million
related to these natural gas forward swaps was included in AOCI as of December 31, 2023, $15 million of which is expected to be reclassified into earnings in
the next 12 months.

In  2020,  the  Company  entered  into  a  $175  million  forward  U.S. Treasury  rate  lock  agreement  to  manage  the  U.S. Treasury  portion  of  its  interest  rate  risk
associated with the anticipated issuance of certain 10-year fixed rate senior notes. The Company designated this outstanding forward U.S. Treasury rate lock
agreement, which expired on December 15, 2022, as a cash flow hedge. The locked fixed rate of this agreement was 0.994%. In September 2022, a gain of
$6  million  was  recognized  as  a  result  of  a  change  in  the  forecasted  issuance  of  certain  senior  notes.  In  December  2022,  the  Company  received  cash  of
$37 million upon the settlement of the rate lock agreement, of which $31 million will be amortized as a component of interest expense upon the future issuance
of senior notes. This unrecognized gain of $31 million was included in AOCI as of December 31, 2023.

Net Investment Hedges

The  Company  has  translation  exposure  resulting  from  translating  the  financial  statements  of  foreign  subsidiaries  into  U.S.  Dollars,  which  is  recognized  in
Currency  translation  adjustment  (a  component  of  AOCI).  In  the  second  quarter  of  2022,  the  Company  terminated  the  remaining  cross-currency  forward
contracts related to the hedged portions of the net investment in foreign subsidiaries, resulting in cash proceeds of $11 million.

Other Derivatives

The Company uses forward currency exchange contracts to manage existing exposures to foreign exchange risk related to assets and liabilities recorded on the
Consolidated  Balance  Sheets.  As  of  December  31,  2023,  the  Company  had  notional  amounts  of  $183  million  for  non-designated  derivative  financial
instruments  related  to  foreign  currency  exposures  in  U.S.  Dollars  primarily  related  to  the  Brazilian  Real,  Indian  Rupee,  Chinese Yuan,  Hong  Kong  Dollar,
South Korean Won, and the European Euro. In addition, the Company had notional amounts of $45 million for non-designated derivative financial instruments
related to foreign currency exposures in European Euro primarily related to the Polish Złoty, British Pound Sterling, and the U.S. Dollar.

The annual tests performed in the fourth quarter of 2023 and 2022 resulted in no impairment of goodwill. The annual 2023 testing indicated that the business
enterprise values for the Roofing and Insulation reporting units substantially exceeded their respective carrying values. The business enterprise value of the
Composites  reporting  unit  exceeded  its  carrying  value  by  approximately  5%.  There  is  uncertainty  surrounding  the  macroeconomic  factors  that  impact  this
reporting unit and a sustained downturn in these factors or a change in the long-term revenue growth or profitability for this reporting unit could increase the
likelihood of a future impairment.

Indefinite-Lived Intangible Assets

Fair  values  used  in  testing  for  potential  impairment  of  our  trademarks  and  trade  names  are  calculated  using  the  relief-from-royalty  method  by  applying  an
estimated  market  value  royalty  rate  to  the  forecasted  revenues  of  the  businesses  that  utilize  those  assets. The  assumed  cash  flows  from  this  calculation  are
discounted at a rate based on a market participant discount rate.

The annual test performed in the fourth quarter of 2023 resulted in no impairment of indefinite-lived intangible assets.

There are two indefinite-lived intangible assets that are at an increased risk of impairment, both of which are used by our Insulation segment and were partially
impaired in the fourth quarter of 2022. A change in the estimated long-term revenue growth rate or discount rate for the segment could increase the likelihood
of a future impairment.

The following table presents the carrying values of these assets as of December 31, 2023 (in millions):

All remaining indefinite-lived intangible assets substantially exceeded their carrying values as of December 31, 2023.

The annual tests performed in the fourth quarter of 2022 resulted in impairment of five of the Company's indefinite-lived intangible assets. Based on the results
of this testing, the Company recorded pre-tax non-cash impairment charges totaling $96 million in the fourth quarter of 2022. These charges were recorded in
Other expense (income), net on the Consolidated Statements of Earnings, and were included in the Corporate, Other and Eliminations reporting category.

These  charges  included  the  following  within  the  Insulation  segment:  a  pre-tax  impairment  charge  of  $63  million  for  a  trade  name  used  by  our  European
building and technical insulation business due to the effect of a higher discount rate, associated with rising interest rates, and general economic and geopolitical
uncertainty within the European markets resulting in a slightly lower profitability outlook; a pre-tax impairment charge of $12 million related to a trademark
used  on  global  cellular  glass  insulation  products  due  to  the  effect  of  a  higher  discount  rate,  associated  with  rising  interest  rates,  and  general  economic  and
geopolitical uncertainty within the European markets; a pre-tax impairment charge of $8 million for a trademark used on stone wool insulation products sold in
the United States due to forecasted profitability of the product line.

5. GOODWILL AND OTHER INTANGIBLE ASSETS (continued)

The remaining $13 million pre-tax impairment charge for trademarks used within the components business in our Roofing segment was due to the effect of a
higher discount rate, associated with rising interest rates, and forecasted profitability of a specific product line.

Definite-Lived Intangible Assets

The Company amortizes the cost of other intangible assets over their estimated useful lives which, individually, range up to 45 years. The Company's future
cash flows are not materially impacted by its ability to extend or renew agreements related to its amortizable intangible assets.

Amortization expense for intangible assets for the years ended December 31, 2023, 2022 and 2021 was $94 million, $55 million, and $49 million, respectively.
In 2023, amortization expense included $25 million of accelerated amortization related to restructuring actions further explained in Note 12 to the Consolidated

6.    PROPERTY, PLANT AND EQUIPMENT (continued)

Our production tooling needs in our Composites segment are changing in response to economic and technological factors. As a result, we exchanged certain
precious metals used in production tooling for certain other precious metals to be used in production tooling. There were no non-cash exchanges during the
twelve  months  ended  December  31,  2023.  During  the  twelve  months  ended  December  31,  2022,  these  non-cash  exchanges  resulted  in  a  net  increase  to
Machinery  and  equipment  of  $18  million  and  gains  totaling  $18  million.  These  gains  are  included  in  Other  expense  (income),  net  on  the  Consolidated
Statements of Earnings and reflected in the Corporate, Other and Eliminations reporting category. These non-cash investing activities are not included in Net
cash  flow  used  by  investing  activities  in  the  Consolidated  Statements  of  Cash  Flows. We  do  not  expect  these  non-cash  exchanges  to  materially  impact  our
current or future capital expenditure requirements or rate of depletion.

For the years ended December 31, 2023, 2022 and 2021, depreciation expense was $481 million, $447 million and $429 million, respectively, which includes
depletion expense related to precious metals used in our production tooling. In 2023, 2022 and 2021, depreciation expense included $76 million, $26 million
and $13 million, respectively, of accelerated depreciation related to restructuring actions further explained in Note 12 to the Consolidated Financial Statements.

7. ACQUISITIONS

On September 1, 2022, the Company acquired the remaining 50% interest in Fiberteq, LLC (“Fiberteq”), the joint venture between Owens Corning and IKO
Industries, Ltd, which produces high-quality wet-formed fiberglass mat for roofing applications for $140 million, net of cash acquired. During the third quarter
of 2023, an additional $6 million of consideration was paid as a result of final working capital adjustments. The acquisition advances the Composites strategy
to  focus  on  high-value  material  solutions  and  expands  Owens  Corning's  capacity  to  produce  non-woven  mat. The  Company's  50%  interest  in  Fiberteq  was
accounted for as an equity-method investment and had a carrying value of $17 million at the acquisition date. The Company used the discounted cash flow
method  to  remeasure  the  previously  held  equity  method  investment  to  its  fair  value  of  $147  million,  resulting  in  the  recognition  of  a  gain  of  $130  million,
which  is  recorded  in  Gain  on  equity  method  investment  on  the  2022  Consolidated  Statements  of  Earnings.  The  operating  results  for  Fiberteq  have  been
included  in  the  Composites  segment  within  the  Consolidated  Financial  Statements  since  the  date  of  the  acquisition. The  purchase  price  allocation  included
$58  million  in  intangible  assets,  which  primarily  consists  of  customer  relationships  with  an  estimated  weighted  average  life  of  3  years,  a  $62  million
unfavorable  contract  liability  and  $242  million  in  goodwill,  of  which  50%  is  tax  deductible.  The  factors  contributing  to  the  recognition  of  the  amount  of
goodwill are based on several strategic and synergistic benefits that are expected to be realized from the acquisition. The pro-forma effect of this acquisition on
revenues and earnings was not material.

On August 1, 2022, the Company acquired Natural Polymers, LLC (“Natural Polymers”), an innovative manufacturer of spray polyurethane foam insulation for
building  and  construction  applications  for  $111  million,  net  of  cash  acquired.  The  acquisition  advances  the  Owens  Corning  strategy  to  strengthen  the
Company's  core  building  and  construction  products  and  expand  its  addressable  markets  into  higher-growth  segments.  The  operating  results  for  Natural
Polymers  have  been  included  in  the  Insulation  segment  within  the  Consolidated  Financial  Statements  since  the  date  of  the  acquisition.  The  purchase  price
allocation included $44 million in intangible assets and $62 million in goodwill, of which all is tax deductible. The intangible assets consist of definite-lived
trademarks of $5 million with an estimated weighted average life of 10 years, technology of $12 million with an estimated weighted average life of 6 years and
customer  relationships  of  $27  million  with  an  estimated  weighted  average  life  of  17  years.  The  factors  contributing  to  the  recognition  of  the  amount  of
goodwill are based on several strategic and synergistic benefits that are expected to be realized from the acquisition. The pro-forma effect of this acquisition on
revenues and earnings was not material.    

On  June  1,  2022,  the  Company  acquired  all  of  the  outstanding  assets  of  WearDeck®,  a  premium  producer  of  composite  weather-resistant  decking  for
commercial and residential applications, for $133 million, net of cash acquired. The acquisition advances the Composites business growth strategy to focus on
high-value  material  solutions  within  the  building  and  construction  industry.  The  operating  results  for  WearDeck®  have  been  included  in  the  Composites
segment within the Consolidated Financial Statements since the date of the acquisition. The purchase price allocation included $38 million in intangible assets
and $68 million in goodwill, of which $61 million is tax deductible. The intangible assets consist of definite-lived trademarks of $7 million with an estimated
average  life  of  10  years,  technology  of  $10  million  with  an  estimated  weighted  average  life  of  11  years  and  customer  relationships  of  $21  million  with  an
estimated weighted average life of 15 years. The factors contributing to the recognition of the amount of goodwill are based on several strategic and synergistic
benefits that are expected to be realized from the acquisition. The pro-forma effect of this acquisition on revenues and earnings was not material.

7.    ACQUISITIONS (continued)

On  May  23,  2022,  Owens  Corning  and  Pultron  Composites  (“Pultron”)  formed  a  joint  venture  (the  “JV”)  to  manufacture  and  sell  fiberglass  rebar.  The
Company  contributed  approximately  $47  million  to  acquire  a  65.5%  controlling  interest  and  has  established  a  redeemable  noncontrolling  interest  of
$25 million related to Pultron, the minority holder. The JV expands Owens Corning’s capability to produce high-value material solutions by combining the
Company’s glass-fiber material technology, channel access and extensive industry experience with Pultron’s manufacturing expertise and process efficiency.
The fully consolidated operating results for the JV have been included in the Company’s Composites segment within the Consolidated Financial Statements
since the date of the formation of the JV. Subsequent to the JV formation, the JV acquired assets and technology from Pultron for approximately $65 million.
The purchase price allocation included $15 million in intangible assets, consisting of technology, with an estimated weighted average life of 15 years and $42
million in goodwill, of which $37 million is tax deductible. The factors contributing to the recognition of the amount of goodwill are based on several strategic
and  synergistic  benefits  that  are  expected  to  be  realized  from  the  acquisition.  The  pro-forma  effect  of  this  acquisition  on  revenues  and  earnings  was  not
material.

On July 13, 2021, the Company acquired vliepa GmbH (“vliepa”), which specializes in the coating, printing, and finishing of non-wovens, paper, and film for
the building materials industry in Europe, for $42 million, net of cash acquired. The acquisition broadens the Company’s global non-wovens portfolio to better
serve  European  customers  and  accelerate  growth  of  building  and  construction  market  applications  in  the  region. The  operating  results  for  vliepa  have  been
included in the Company’s Composites segment within the Consolidated Financial Statements since the date of the acquisition. The acquisition resulted in the
recognition of $13 million in intangible assets, primarily consisting of customer relationships with an estimated weighted average life of 12 years, and $16
million in goodwill. The pro-forma effect of this acquisition on revenues and earnings was not material.

8.    DIVESTITURES

During the third quarter of 2021, the Company entered into a purchase and sale agreement for the Company’s Insulation site in Santa Clara, California and
ceased operations in the fourth quarter of 2022. Assets held for sale as of December 31, 2022 were $45 million and primarily consisted of land. In March 2023,
the  Company  finalized  the  sale  for  total  proceeds  of  $234  million,  net  of  transaction  fees. Total  proceeds  included  a  non-refundable  deposit  of  $50  million
received in the third quarter of 2021. As a result, the Company recognized a pre-tax gain of $189 million in the first quarter of 2023, which is recorded in Gain
on sale of site on the Consolidated Statements of Earnings.

On November 24, 2022, the Company finalized the sale of its Russian operations within the Composites and Insulation segments. As a result of this sale, the
Company  received  $104  million,  net  of  cash  sold,  in  consideration  and  recorded  a  pre-tax  loss  of  $33  million  in  Other  expense  (income),  net  on  the
Consolidated Statements of Earnings.

On July 1, 2022, the Company finalized the sale of the European portion of the dry-use chopped strands (“DUCS”) product line located in Chambéry, France,
within the Composites segment. As a result of this sale, the Company received $80 million, net of cash sold, in consideration and recorded a pre-tax loss of

9.    LEASES

The  Company  leases  certain  equipment  and  facilities  under  both  operating  and  finance  leases  expiring  on  various  dates  through  2050.  The  nature  of  these
leases generally fall into the following five categories: real estate, material handling equipment, fleet vehicles, office equipment and energy equipment.

For leases with initial terms greater than 12 months, we consider these our right-of-use assets and record the related asset and obligation at the present value of
lease payments over the term. For leases with initial terms equal to or less than 12 months, we do not consider them as right-of-use assets and instead consider
them short-term lease costs that are recognized on a straight-line basis over the lease term.

Our  leases  may  include  escalation  clauses,  renewal  options  and/or  termination  options  that  are  factored  into  our  determination  of  lease  payments  when
reasonably certain. These options to extend or terminate a lease are at our discretion. We have elected to take the practical expedient and not separate lease and
non-lease  components  of  contracts.  We  estimate  our  incremental  borrowing  rate  to  discount  the  lease  payments  based  on  information  available  at  lease
commencement. Our lease agreements do not contain any material residual value guarantees.

12. RESTRUCTURING, ACQUISITION AND DIVESTITURE-RELATED COSTS

The Company may incur restructuring, transaction and integration costs related to acquisitions and divestitures, and may incur restructuring and other exit costs
in connection with its global cost reduction, product line and productivity initiatives and the Company’s growth strategy.

Global Composites Restructuring
In December 2023, the Company took actions to reduce costs throughout its global Composites segment given current market conditions, primarily through
global workforce reductions, as well as streamlining manufacturing and supply chain operations. These actions primarily include salaried workforce reductions
and the relocation of the Changzhou, China operations to Hangzhou, China.

In connection with these actions, the Company estimates it will incur cash charges in the range of $20 million to $30 million, primarily related to severance and
other exit costs, including termination costs, and non-cash charges in the range of $15 million to $20 million, primarily related to accelerated depreciation.

During  2023,  the  Company  recorded  $16  million  of  charges,  of  which  $4  million  were  non-cash  charges,  primarily  related  to  accelerated  depreciation  and
$12 million of cash charges, primarily related to severance.

Building Materials Asia-Pacific Optimization
In December 2023, the Company took actions to further its ongoing cost optimization strategy for the Insulation segment by permanently closing the Xi'an,
China facility, which had previously ceased operations, and permanently closing one idled production line at the Guangde, China facility. These actions are
expected to result in cumulative costs of approximately $20 million, primarily related to accelerated depreciation.

During  2023,  the  Company  recorded  $18  million  of  charges  primarily  related  to  accelerated  depreciation.  The  Company  does  not  expect  to  recognize
significant incremental costs related to these actions.

Protective Packaging Exit
In May 2023, the Company made the decision to exit the Protective Packaging business within the Roofing segment, including the production and sale of wood
packaging,  metal  packaging  and  custom  products.  Exiting  Protective  Packaging  will  allow  the  Company  to  focus  resources  on  the  growth  of  its  building
materials products, which supports the future growth aspirations of the enterprise. With the exit of the Protective Packaging business, the Company closed its
plants in Dorval, Quebec and Mission, British Columbia, Canada. The Company also ceased operations at its Qingdao, China facility.

In connection with the exit of the Protective Packaging business, the Company estimates that it will incur cash charges of approximately $15 million, primarily
related to severance and other exit costs. Additionally, the Company will incur total non-cash charges in the range of $70 to $75 million, primarily related to
accelerated depreciation of property, plant and equipment and accelerated amortization of definite-lived intangibles.

During  2023,  the  Company  recorded  $78  million  of  charges,  of  which  $69  million  were  non-cash  charges,  primarily  related  to  accelerated  depreciation,
amortization and inventory write-offs and $9 million of cash charges, primarily related to severance.

Wabash Facility Closure
In April 2023, the Company took actions to support its strategy to operate a flexible and cost-efficient manufacturing network through decisions to relocate the
Wabash,  Indiana  mineral  wool  operations  to  Joplin,  Missouri,  and  to  exit  the  U.S.  granulated  mineral  wool  market. These  actions  are  expected  to  result  in
cumulative costs of approximately $30 million, primarily related to severance and accelerated depreciation.

During 2023, the Company recorded $33 million of charges, primarily related to accelerated depreciation, severance and other exit costs. The Company does
not expect to recognize significant incremental costs related to these actions.

12.    RESTRUCTURING, ACQUISITION AND DIVESTITURE-RELATED COSTS (continued)

European Operating Structure Optimization
In March 2023, the Company took actions to optimize the operating structure of its segments across Europe to increase its competitiveness. These actions are
expected to result in cumulative costs of approximately $20 million, primarily related to severance and other exit costs.

During 2023, the Company recorded $12 million of charges primarily related to severance costs.

Composites Strategic Realignment Actions
On  July  1,  2022,  the  Company  finalized  the  sale  of  the  European  portion  of  the  DUCS  product  line  located  in  Chambéry,  France,  within  the  Company's
Composites segment. The Company recorded a pre-tax charge of $30 million in Other expense (income), net on the Consolidated Statements of Earnings in
2022 to reflect the fair value less cost to sell the assets. The Company also took actions to convert the DUCS manufacturing facilities located in Anderson,
South Carolina and Kimchon, Korea to produce other glass fiber products needed to support our growth strategy in building and construction applications.

As  a  result,  during  2023,  the  Company  recorded  $2  million  of  charges  primarily  related  to  other  exit  costs.  The  Company  does  not  expect  to  recognize
significant incremental costs related to these actions.

Roofing Restructuring Actions
In December 2021, the Company took actions to restructure operations within the Roofing segment's components product line by relocating production assets
from China to India, which allowed the business to optimize its manufacturing network and support a tariff mitigation strategy.

During  2023,  the  Company  recorded  $2  million  of  charges  primarily  related  to  other  exit  costs.  The  Company  does  not  expect  to  recognize  significant
incremental charges related to these actions.

Santa Clara Insulation Site
During  the  third  quarter  of  2021,  the  Company  entered  into  a  sales  agreement  for  the  Company's  Insulation  site  in  Santa  Clara,  California  as  part  of  the
Company's on-going strategy to operate a flexible, cost-efficient manufacturing network and geographically locate its assets to better serve its customers. On
March 3, 2023, the Company finalized the sale of this site for total proceeds of $234 million, net of transaction fees. Total proceeds included a non-refundable
deposit of $50 million received in the third quarter of 2021.

During  2023,  the  Company  recorded  $6  million  of  charges,  primarily  related  to  other  exit  costs.  The  Company  does  not  expect  to  recognize  significant
incremental costs related to this action.

1 each year, beginning on June 1, 2007. The proceeds of these notes were used to pay certain unsecured and administrative claims, finance general working
capital needs and for general corporate purposes.

Collectively, the senior notes above are referred to as the “Senior Notes.” The Senior Notes are general unsecured obligations of the Company and rank pari
passu with all existing and future senior unsecured indebtedness of the Company.

The Company has the option to redeem all or part of the Senior Notes at any time at a “make-whole” redemption price. The Company is subject to certain
covenants in connection with the issuance of the Senior Notes that it believes are usual and customary. The Company was in compliance with these covenants
as of December 31, 2023.

Senior Revolving Credit Facility

The Company has an $800 million senior revolving credit facility (the “Senior Revolving Credit Facility”) with a maturity date in July 2026 that includes both
borrowings and letters of credit. Borrowings under the Senior Revolving Credit Facility may be used for general corporate purposes and working capital. The
Company has the discretion to borrow under multiple options, which provide for varying terms and interest rates including the United States prime rate, federal
funds rate plus a spread or the Secured Overnight Financing Rate (“Term SOFR”) plus a spread.

The  Senior  Revolving  Credit  Facility  contains  various  covenants,  including  a  maximum  allowed  leverage  ratio,  that  the  Company  believes  are  usual  and
customary for a senior unsecured credit agreement. The Company was in compliance with these covenants as of December 31, 2023. Please refer to the Credit
Facility Utilization section below for liquidity information as of December 31, 2023.

In May 2023, the Senior Revolving Credit Facility was amended to formally adopt Term SOFR plus a spread as the benchmark reference rate in anticipation of
the June 30, 2023 discontinuation of the London Interbank Offered Rate (“LIBOR”).

Receivables Securitization Facility

The  Company  has  a  Receivables  Purchase Agreement  (“RPA”)  that  is  accounted  for  as  secured  borrowings  in  accordance  with ASC  860,  “Accounting  for
Transfers and Servicing.” Owens Corning Sales, LLC and Owens Corning Receivables LLC, each a subsidiary of the Company, have a $280 million RPA with
certain financial institutions. The Company has the ability to borrow at the lenders' cost of funds, which approximates A-1/P-1 commercial paper rates vs. Term
SOFR plus a spread. As of the June 30, 2023 discontinuation of LIBOR, fallback language in the RPA took effect to transition the facility to Term SOFR plus a
spread. The RPA has been amended from time to time, with a maturity date in April 2024.

The  RPA  contains  various  covenants,  including  a  maximum  allowed  leverage  ratio,  that  the  Company  believes  are  usual  and  customary  for  a  securitization
facility.  The  Company  was  in  compliance  with  these  covenants  as  of  December  31,  2023.  Please  refer  to  the  Credit  Facility  Utilization  section  below  for
liquidity information as of December 31, 2023.

14.    PENSION PLANS

Pension Plans

The Company sponsors defined benefit pension plans. Under the plans, pension benefits are based on an employee’s years of service and, for certain categories
of employees, qualifying compensation. Company contributions to these pension plans are determined by an independent actuary to meet or exceed minimum
funding requirements. In our U.S. plan, the unrecognized cost of any retroactive amendments and actuarial gains and losses are amortized over the average
remaining life expectancy of inactive participants. In all of our Non-U.S. plans, the unrecognized cost of any retroactive amendments and actuarial gains and
losses are amortized over the average future service period of plan participants expected to receive benefits.

During  the  fourth  quarter  of  2023,  the  Company  entered  into  two  agreements  to  purchase  non-participating  annuity  contracts  from  insurance  companies  to
transfer $291 million of the Company's outstanding pension projected benefit obligation (“PBO”) related to certain U.S. and non-U.S. pension plans. These
transactions were funded with pension plan assets of $268 million. As a result of these transactions, the Company recognized a pre-tax settlement charge of
$145 million in the fourth quarter of 2023 from the accelerated recognition of a pro rata portion of plan actuarial losses. This charge was recorded in Non-
operating expense (income), net on the Consolidated Statements of Earnings. These transactions did not have a material effect on the plans' funded statuses.

The following tables provide a reconciliation of the change in the projected benefit obligation, the change in plan assets and the net amount recognized in the
Consolidated Balance Sheets (in millions):

For the year ended December 31, 2023, the actuarial gain of $12 million was largely the result of the impacts related to the annuity purchase settlement offset
by  losses  due  to  decreased  discount  rates.  In  the  U.S.  plan,  the  actuarial  gain  was  primarily  driven  by  the  settling  of  the  annuity  purchase  at  a  lower  value
relative  to  the  PBO  held  at  the  time.  The  gain  was  slightly  offset  by  an  actuarial  loss  due  to  the  decrease  in  the  discount  rate.  In  the  Non-U.S.  plans,  the
actuarial loss was primarily driven by a decrease in the discount rates across all the plans.

For the year ended December 31, 2022, the actuarial gain of $277 million was largely the result of increases in discount rates across all plans. In the U.S. plan,
the  actuarial  gain  was  primarily  driven  by  the  increase  in  the  discount  rate. The  gain  was  slightly  offset  by  the  unfavorable  impact  of  differences  between
expected and actual pension experience. In the Non-U.S. plans, the actuarial gain was driven by an increase in the discount rate of the U.K. and Canada plans,
partially offset by the unfavorable impact of differences between expected and actual pension experience.

The  following  table  presents  information  about  the  projected  benefit  obligation,  accumulated  benefit  obligation  (“ABO”)  and  plan  assets  of  the  Company’s

(a) Not applicable due to changes in plan made on August 1, 2009 that were effective beginning January 1, 2010.

The expected return on plan assets assumption is derived by taking into consideration the target plan asset allocation, historical rates of return on those assets,
projected future asset class returns and net outperformance of the market by active investment managers. An asset return model is used to develop an expected
range  of  returns  on  plan  investments  over  a  30  year  period,  with  the  expected  rate  of  return  selected  from  a  best  estimate  range  within  the  total  range  of
projected results. The result is then rounded down to the nearest 25 basis points.

Items Measured at Fair Value

The Company classifies and discloses pension plan assets in one of the following three categories:

Level 1: Quoted market prices in active markets for identical assets.

Level 2: Observable market-based inputs or unobservable inputs that are corroborated by market data.

Level 3: Unobservable inputs that are not corroborated by market data.

Plan Assets

The tables in this section show pension plan asset fair values and fair value leveling information. The assets are categorized into one of the three levels of the
fair value hierarchy or are not subject to leveling, in the case of investments that are valued using the net asset value per share (or its equivalent) practical
expedient (“NAV”).

The current targeted asset allocation for the United States pension plan is to have 23% of assets invested in equities, 70% in intermediate and long-term fixed
income  securities,  high  yield  and  cash  and  7%  in  other  strategies. Assets  are  rebalanced  at  least  quarterly  to  conform  to  policy  tolerances.  The  Company
actively evaluates the reasonableness of its asset mix given changes in the projected benefit obligation and market dynamics. Our investment policy and asset

The Company expects to contribute $20 million in cash to its defined benefit pension plans during 2024. Actual contributions to the plans may change as a
result of a variety of factors, including changes in laws that impact funding requirements.

Defined Contribution Plans

The Company sponsors two defined contribution plans which are available to substantially all United States employees. The Company matches a percentage of
employee  contributions  up  to  a  maximum  level  and  contributes  up  to  2%  of  an  employee’s  wages  regardless  of  employee  contributions.  The  Company
recognized expense of $65 million, $57 million and $52 million during the years ended December 31, 2023, 2022 and 2021, respectively, related to these plans.

15.    POSTEMPLOYMENT AND POSTRETIREMENT BENEFITS OTHER THAN PENSIONS

The Company maintains health care and life insurance benefit plans for certain retired employees and their dependents. The health care plans in the United
States  are  non-funded  and  pay  either  (1)  stated  percentages  of  covered  medically  necessary  expenses,  after  subtracting  payments  by  Medicare  or  other
providers and after stated deductibles have been met, or (2) fixed amounts of medical expense reimbursement.

Employees  hired  on  or  before  December  31,  2005  become  eligible  to  participate  in  the  United  States  health  care  plans  upon  retirement  if  they  have
accumulated 10 years of service after age 45, 48 or 50, depending on the category of employee. For employees hired after December 31, 2005, the Company
does  not  provide  subsidized  retiree  health  care.  Some  of  the  plans  are  contributory,  with  some  retiree  contributions  adjusted  annually.  The  Company  has
reserved the right to change or eliminate these benefit plans subject to the terms of collective bargaining agreements.

The  following  table  provides  a  reconciliation  of  the  change  in  the  projected  benefit  obligation  and  the  net  amount  recognized  in  the  Consolidated  Balance

16.    CONTINGENT LIABILITIES AND OTHER MATTERS

The Company may be involved in various legal and regulatory proceedings relating to employment, antitrust, tax, product liability, environmental, contracts,
intellectual property and other matters (collectively, “Proceedings”). The Company regularly reviews the status of such Proceedings along with legal counsel.
Liabilities for such Proceedings are recorded when it is probable that the liability has been incurred and when the amount of the liability can be reasonably
estimated. Liabilities are adjusted when additional information becomes available. Management believes that the amount of any reasonably possible losses in
excess of any amounts accrued, if any, with respect to such Proceedings or any other known claim, including the matters described below under the caption
Environmental  Matters  (the  “Environmental  Matters”),  are  not  material  to  the  Company’s  financial  statements.  Management  believes  that  the  ultimate
disposition  of  the  Proceedings  and  the  Environmental  Matters  will  not  have  a  material  adverse  effect  on  the  Company’s  financial  condition.  While  the
likelihood is remote, the disposition of the Proceedings and Environmental Matters could have a material impact on the results of operations, cash flows or
liquidity in any given reporting period.

Litigation and Regulatory Proceedings

The Company is involved in litigation and regulatory proceedings from time to time in the regular course of its business. The Company believes that adequate
provisions for resolution of all contingencies, claims and pending matters have been made for probable losses that are reasonably estimable.

During  the  second  quarter  of  2023,  the  Company's  subsidiary,  Paroc  Group  OY  (“Paroc”),  which  the  Company  acquired  in  2018,  notified  the  appropriate
European  maritime  regulatory  authorities  that  specific  products  in  its  marine  insulation  product  line  may  not  meet  certain  fire  safety  requirements  in
accordance with their certifications. Paroc voluntarily withdrew these specific products from the market, issued recalls, and suspended distribution and sales of
these products. Paroc continues to cooperate with the applicable regulatory and government authorities and work with its customers and end-users to assist with
remediation. During 2023, the Company established an estimated liability for expected future costs related to the marine recall on our Consolidated Balance
Sheet as of December 31, 2023. The estimated liability is primarily based on assumptions related to the estimated costs of the remedy for the recall. We will
reevaluate these assumptions each period, and the related liability may be adjusted when factors indicate that the liability is either not sufficient to cover or
exceeds the estimated product recall costs. Based on the factors currently known, we believe the appropriate liability has been established at this time. It is
reasonably  possible  that  additional  product  recall  costs  could  be  incurred  that  exceed  the  estimated  liability  by  amounts  that  could  be  material  to  our
consolidated financial statements.

As  part  of  its  review  of  the  Paroc  insulation  product  portfolio,  the  Company  discovered  potential  nonconformances  relating  to  certain  ventilation  duct
insulation  products.  In  January  2024,  Paroc  suspended  sales  of  the  affected  insulation  products  as  a  precautionary  measure  while  it  reviews  the  potential
nonconformances. The Company is continuing its review.

Environmental Matters

The Company has established policies and procedures designed to ensure that its operations are conducted in compliance with all relevant laws and regulations
and that enable the Company to meet its high standards for corporate sustainability and environmental stewardship. Our manufacturing facilities are subject to
numerous foreign, federal, state and local laws and regulations relating to the presence of hazardous materials, pollution and protection of the environment,
including emissions to air, reductions of greenhouse gases, discharges to water, management of hazardous materials, handling and disposal of solid wastes, use
of chemicals in our manufacturing processes, and remediation of contaminated sites. All Company manufacturing facilities are either ISO 14001 certified or
deploy  environmental  management  systems  based  on  ISO  14001  principles. The  Company’s  2030  Sustainability  Goals  include  targets  related  to  significant
global  reductions  in  energy  use,  water  consumption,  waste  to  landfill,  and  emissions  of  greenhouse  gases,  fine  particulate  matter,  and  volatile  organic  air
emissions, and protection of biodiversity.

Owens  Corning  is  involved  in  remedial  response  activities  and  is  responsible  for  environmental  remediation  at  a  number  of  sites,  including  certain  of  its
currently  owned  or  formerly  owned  plants.  These  responsibilities  arise  under  a  number  of  laws,  including,  but  not  limited  to,  the  Federal  Resource
Conservation  and  Recovery Act,  and  similar  state  or  local  laws  pertaining  to  the  management  and  remediation  of  hazardous  materials  and  petroleum.  The
Company has also been named a potentially responsible party under the U.S. Federal Superfund law, or state equivalents, at a number of disposal sites. The
Company

-106-
OWENS CORNING AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (continued)

16. CONTINGENT LIABILITIES AND OTHER MATTERS (continued)

became  involved  in  these  sites  as  a  result  of  government  action  or  in  connection  with  business  acquisitions. As  of  December  31,  2023,  the  Company  was
involved with a total of 22 sites worldwide, including 10 Superfund and state or country equivalent sites and 12 owned or formerly owned sites. None of the
liabilities for these sites are individually significant to the Company.

Remediation activities generally involve a potential range of activities and costs related to soil, groundwater, and sediment contamination. This can include pre-
cleanup activities such as fact-finding and investigation, risk assessment, feasibility studies, remedial action design and implementation (where actions may
range from monitoring to removal of contaminants, to installation of longer-term remediation systems). A number of factors affect the cost of environmental
remediation, including the number of parties involved in a particular site, the determination of the extent of contamination, the length of time the remediation
may require, the complexity of environmental regulations, variability in clean-up standards, the need for legal action, and changes in remediation technology.
Taking these factors into account, Owens Corning has predicted the costs of remediation reasonably estimated to be paid over a period of years. The Company
accrues an amount on an undiscounted basis, consistent with the reasonable estimates of these costs when it is probable that a liability has been incurred. Actual
cost may differ from these estimates for the reasons mentioned above. At December 31, 2023, the Company had an accrual totaling $4 million for these costs,
of  which  the  current  portion  is  $1  million.  Changes  in  required  remediation  procedures  or  timing  of  those  procedures,  or  discovery  of  contamination  at
additional sites, could result in material increases to the Company’s environmental obligations.

17. STOCK COMPENSATION

Description of the Plan

On April  20,  2023,  the  Company's  stockholders  approved  the  Owens  Corning  2023  Stock  Plan  (the  “2023  Stock  Plan”)  which  authorizes  grants  of  stock
options, stock appreciation rights, stock awards (including restricted stock awards, restricted stock units and bonus stock awards), performance share awards
and performance share units. At December 31, 2023, the number of shares remaining available under the 2023 Stock Plan for all stock awards was 3.4 million.

Prior to the 2023 Stock Plan, employees were eligible to receive stock awards under the Owens Corning 2019 Stock Plan.

Stock Options

The Company has granted stock options under its stockholder approved stock plans. The Company calculates a weighted-average grant-date fair value using a
Black-Scholes valuation model for options granted. Compensation expense for options is measured based on the fair market value of the option on the date of
grant, and is recognized on a straight-line basis over a four-year vesting period. In general, the exercise price of each option awarded was equal to the closing
market  price  of  the  Company’s  common  stock  on  the  date  of  grant  and  an  option’s  maximum  term  is  10  years.  The  volatility  assumption  was  based  on  a
benchmark study of our peers prior to 2014. Starting with the options granted in 2014, the volatility was based on the Company’s historic volatility.

The Company has not granted stock options since the year ended December 31, 2014. As of December 31, 2023, there was no unrecognized compensation cost
related to stock options and the exercise prices on outstanding stock options was $37.65.

The Company has granted restricted stock units (“RSUs”) under its stockholder-approved stock plans. Generally, all outstanding RSUs will fully settle in stock.
Compensation expense for RSUs is measured based on the closing market price of the stock at date of grant and is recognized on a straight-line basis over the
vesting period, which is typically three or four years. The Stock Plan allows alternate vesting schedules for death, disability and retirement.

The weighted average grant date fair value of RSUs granted in 2023, 2022 and 2021 was $104.27, $90.41 and $84.03, respectively.

As  of  December  31,  2023,  there  was  $40  million  of  total  unrecognized  compensation  cost  related  to  RSUs.  That  cost  is  expected  to  be  recognized  over  a
weighted-average  period  of  2.42  years.  The  total  grant  date  fair  value  of  stock  vested  during  the  years  ended  December  31,  2023,  2022  and  2021  was
$27 million, $22 million and $26 million, respectively.

Performance Share Units

The  Company  has  granted  performance  share  units  (“PSUs”)  as  a  part  of  its  long-term  incentive  plan. All  outstanding  PSUs  will  fully  settle  in  stock. The
amount of shares ultimately distributed from the 2023, 2022 and 2021 grants is contingent on meeting internal company-based metrics or an external-based
stock performance metric.

In 2023, 2022 and 2021, the Company granted both internal company-based and external-based metric PSUs.

 
 
-108-
OWENS CORNING AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (continued)

17. STOCK COMPENSATION (continued)

Internal Company-based metrics

The internal Company-based metric PSUs are based on various Company metrics and typically vest after a three-year period. The amount of stock distributed
will vary from 0% to 200% of PSUs awarded depending on each award's design and performance versus the Company-based metrics.

The initial fair value for all internal company-based metric PSUs assumes that the performance goals will be achieved and is based on the grant date stock
price.  This  assumption  is  monitored  quarterly  and  if  it  becomes  probable  that  such  goals  will  not  be  achieved  or  will  be  exceeded,  compensation  expense
recognized will be adjusted and previous surplus compensation expense recognized will be reversed or additional expense will be recognized. The expected
term represents the period from the grant date to the end of the three-year performance period. Pro-rata vesting may be utilized in the case of death, disability
or retirement, and awards, if earned, will be paid at the end of the three-year period.

The following table provides a summary of the grant date fair values of the internal Company-based metric PSUs:

Twelve Months Ended December 31,

$78.01

The  external-based  metric  PSUs  vest  after  a  three-year  period.  Outstanding  grants  issued  in  or  after  2018  until  2022  were  based  on  the  Company’s  total
stockholder  return  relative  to  the  performance  of  the  Dow  Jones  U.S.  Construction  &  Materials  Index.  Outstanding  grants  issued  in  2023  are  based  on  the
Company’s total stockholder return relative to a peer group. The amount of stock distributed will vary from 0% to 200% of PSUs awarded depending on the
relative stockholder return performance. The fair value of external-based metric PSUs has been estimated at the grant date using a Monte Carlo simulation that
uses various assumptions.

The following table provides a summary of the assumptions for PSUs granted in 2023, 2022 and 2021:

The risk-free interest rate was based on zero-coupon United States Treasury STRIPS at the grant date. The expected term represents the period from the grant
date to the end of the three-year performance period.

PSU Summary

As  of  December  31,  2023,  there  was  $17  million  total  unrecognized  compensation  cost  related  to  PSUs.  That  cost  is  expected  to  be  recognized  over  a
weighted-average  period  of  1.64  years.  The  total  grant  date  fair  value  of  shares  vested  during  the  years  ended  December  31,  2023,  2022  and  2021,  was

The Owens Corning Employee Stock Purchase Plan (“ESPP”) is a tax-qualified plan under Section 423 of the Internal Revenue Code. The purchase price of
shares purchased under the ESPP is equal to 85% of the lower of the fair market value of shares of Owens Corning common stock at the beginning or ending of
the offering period, which is a six month period ending on May 31 and November 30 of each year. On April 16, 2020, the Company's stockholders approved
the Amended  and  Restated  Owens  Corning  Employee  Stock  Purchase  Plan  which  increased  the  number  of  shares  available  for  issuance  under  the  plan  by
4.2 million shares. As of December 31, 2023, 3.2 million shares remain available for purchase.

Included in total stock-based compensation expense is $7 million, $6 million and $6 million of expense related to the Company's ESPP for the years ended
December 31, 2023, 2022 and 2021, respectively. As of December 31, 2023, the Company had $3 million of total unrecognized compensation costs related to
the  ESPP.  Under  the  outstanding  ESPP  as  of  February  9,  2024,  employees  have  contributed  $5  million  to  purchase  shares  for  the  current  purchase  period

Basic  earnings  per  share  is  calculated  by  dividing  earnings  attributable  to  Owens  Corning  by  the  weighted-average  number  of  shares  of  the  Company’s
common stock outstanding during the period. Outstanding shares consist of issued shares less treasury stock.

The  Board  of  Directors  approved  two  share  repurchase  programs  in  2022  under  which  the  Company  is  authorized  to  repurchase  up  to  an  aggregate  of  20
million  shares  of  the  Company’s  outstanding  common  stock  (the  “Repurchase  Authorization”).  The  Repurchase  Authorization  enables  the  Company  to
repurchase shares through the open market, privately negotiated, or other transactions. The actual number of shares repurchased will depend on timing, market
conditions  and  other  factors  and  will  be  at  the  Company’s  discretion. The  Company  repurchased  5.4  million  shares  of  its  common  stock  for  $629  million,
inclusive  of  applicable  taxes,  during  the  year  ended  December  31,  2023  under  the  Repurchase Authorization. As  of  December  31,  2023,  8.9  million  shares
remained available for repurchase under the Repurchase Authorization.

For the year ended December 31, 2023, the Company did not have any non-vested restricted stock units or non-vested performance share units that had an anti-
dilutive effect on earnings per share. For the year ended December 31, 2022, the Company did not have any non-vested restricted stock units or non-vested
performance  share  units  that  had  an  anti-dilutive  effect  on  earnings  per  share.  For  the  year  ended  December  31,  2021,  the  number  of  shares  used  in  the
calculation of diluted earnings per share did not include 0.1 million shares of Company stock underlying unvested performance share units due to their anti-
dilutive effect.

The Company continues to assert indefinite reinvestment in accordance with ASC 740 based on the laws as of enactment of the Tax Act. As of December 31,
2023, the Company has not provided for withholding or income taxes on approximately $1.5 billion of undistributed reserves of its foreign subsidiaries and
affiliates as they are considered by management to be permanently reinvested. Quantification of the deferred tax liability associated with these undistributed
reserves is not practicable.

The use of certain of the Company's domestic loss carryforwards is limited pursuant to Internal Revenue Code (IRC) Section 382. IRC Section 382
imposes an annual limitation on a corporation's ability to use loss carryforwards that arose before a change in control. A change in control is generally
defined as a cumulative change of more than 50% in the ownership positions of certain stockholders during a rolling three-year period. The Company
believes that these limitations will not result in the loss of any of the loss carryforwards.
The foreign net operating losses are related to various jurisdictions that provide for both indefinite carryforward periods and others with carryforward
periods that range from the tax years 2024 to 2033.

Deferred income taxes are provided for temporary differences between amounts of assets and liabilities for financial reporting purposes and the basis of such
assets  and  liabilities  as  measured  under  enacted  tax  laws  and  regulations,  as  well  as  NOLs,  tax  credits  and  other  tax  carryforwards.  We  have  a  variety  of
deferred tax assets in numerous tax jurisdictions. These deferred tax assets are subject to periodic assessment as to recoverability and if it is determined that it is
more likely than not that the benefits will not be realized, valuation allowances are recognized. In evaluating whether it is more likely than not that we would
recover these deferred tax assets, future taxable income, the reversal of existing temporary differences and tax planning strategies are considered.

We believe that our estimates for the valuation allowances recorded against deferred tax assets are appropriate based on current facts and circumstances. As of
December 31, 2023 we had $140 million of valuation allowances on deferred tax assets, on a

tax-effected basis, primarily related to U.S. federal foreign tax credit carryforwards and certain foreign deferred tax attributes as it is more likely than not that
some portion or all of these tax attributes will not be realized.

We file a consolidated federal income tax return in the United States as well as tax returns in multiple state, local and foreign jurisdictions. In the normal course
of business, the Company is subject to examination by the taxing authorities in each of the jurisdictions where we file tax returns. The Company is no longer
subject to U.S. federal tax examinations for years before 2020 or state and foreign examinations for years before 2014.

We  have  on-going  audits  in  various  stages  of  completion  in  several  state  and  foreign  jurisdictions,  one  or  more  of  which  may  conclude  within  the  next  12
months.  Such  settlements  could  involve  some  or  all  of  the  following:  the  payment  of  additional  taxes,  the  adjustment  of  certain  deferred  taxes  and/or  the
recognition  of  unrecognized  tax  benefits.  The  resolution  of  these  matters,  in  combination  with  the  expiration  of  certain  statutes  of  limitations  in  various
jurisdictions, make it reasonably possible that our unrecognized tax benefits may decrease as a result of either payment or recognition by up to $44 million in
the next 12 months, excluding interest.

A reconciliation of the beginning and ending amounts of unrecognized tax benefits is as follows (in millions):

If these unrecognized tax benefits were to be recognized as of December 31, 2023, the Company’s income tax expense would decrease by about $58 million.

The Company recognizes all interest and penalties related to unrecognized tax benefits as a component of income tax expense. Accrued interest and penalties,
which  are  not  presented  in  the  rollforward  table  above,  were  $9  million,  $7  million  and  $7  million  as  of  December  31,  2023,  2022  and  2021,  respectively.
Related to interest and penalties, we recognized an income tax expense of $2 million, $1 million and $2 million, as of December 31, 2023, 2022 and 2021,
respectively.

21.    SUBSEQUENT EVENTS

On  February  8,  2024,  the  Company  entered  into  a  definitive  agreement  to  purchase  all  of  the  outstanding  shares  of  Masonite.  The  purchase  price  for  the
acquisition of Masonite is approximately $3.9 billion in cash, which we expect to fund with cash on hand and new committed financing. Masonite is a leading
global  designer,  manufacturer,  marketer  and  distributor  of  interior  and  exterior  doors  and  door  systems  for  the  new  construction  and  repair,  renovation  and
remodeling sectors of the residential and non-residential building construction markets. The transaction was unanimously approved by the board of directors of
both  companies  and  is  expected  to  close  mid-2024,  subject  to  regulatory  and  other  customary  closing  conditions,  including  the  approval  of  Masonite
shareholders.

On February 9, 2024, the Company announced the decision to review strategic alternatives for its global glass reinforcements (“GR”) business, consistent with
our strategy to focus on building and construction materials. The GR business, which operates within our Composites segment, supplies a wide variety of glass
fiber products for applications in wind energy, infrastructure, industrial, transportation, and consumer markets. The GR business generates annual revenues of
approximately $1.3 billion and has operations in 11 countries, with 18 manufacturing facilities. While a range of options are under consideration, including a
potential sale, spin-off or other strategic option, there can be no assurance that the strategic review will result in any transaction or other outcome.
