Lastly, our design capabilities ensure that the application is designed perfectly for the specific end use. Senior management also uses operating income before special items to assess performance and allocate resources because senior management believes that these measures are useful in understanding current profitability levels and how it may serve as a basis for future performance. The presentation of these measures may be different from non-GAAP financial measures used by other companies.

Use of Non-GAAP Measures This presentation includes the use of both GAAP (generally accepted accounting principles) and non-GAAP financial measures. Lastly, our design capabilities ensure that the application is designed perfectly for the specific end use. Senior management also uses operating income before special items to assess performance and allocate resources because senior management believes that these measures are useful in understanding current profitability levels and how it may serve as a basis for future performance.

Seasonality and Backlog Sales of our products and services are seasonal as demand is generally slower in the first and fourth calendar quarters of the year. For a discussion regarding the significant assumptions used to estimate pension expense, including discount rate, expected long-term rate of return on plan assets and mortality, and how our financial statements can be affected by pension plan accounting policies, see "Critical Accounting Policies" and estimates included in Item 7, "Management's Discussion and Analysis of Financial Condition and Results of Operations." The feasibility study does not contemplate who is responsible for remediation nor does it determine how such costs will be allocated to PRPs.

plastics) stigmatized Rising expectations for rapid innovation and displacement of older, heavily carbon- intensive designs and manufacturing processes NDC countries expected to innovate and seek rapid minimization of customers' scope 3 emissions Increased concern from stakeholders for not addressing climate change globally or for the chemicals sector Acute & Chronic Risk L Possible direct damage to fixed assets and logistics disruptions in both our value chain and operations More frequent and intense weather events and changing preciptation patterns are likely to damage manufaturing faciliites, disrupt logistics and sourcing activities, and negatively affect employee health and communities where we operate More frequent and intense weather events and changing preciptation patterns are likely to affect the performance of grids and thermal plants while pushing up demand for cooling, damage fixed assets, disrupt logistics and sourcing activities, and negatively affect employee health and communities where we operate IMPACT DRIVER & TIME HORIZON NET ZERO FUTURE PLEDGING PROGRESS STEADFAST POLICY Resource Efficiency Opportunity S M L More efficient production and distribution processes, reduced natural resource usage, continued use of recycling, and inclusion of recycled materials in our products such as reSoundTM R, ColorMatrix™ Capture™ Oxygen Scavenger, among others will contribute to increasing product revenues and reduced operating costs Resource efficiency efforts supported by capital allocation in NDC countries is more likely and may accelerate a path toward maximizing ROI and reducing operating costs Less regulatory and pressure to incentivize may cause gains from efforts to lag Energy Source Opportunity M L Use of greater external financing options, such as operating lease arrangements or energy performance shared savings contracts, to source lower emission-energy and new technologies, such as carbon capture, utilization & storage (CCUS), in our operations may reduce operating costs and maximize returns on investment Use of lower emission-sources of energy in operations will lower operating costs and contribute toward reductions of our scope 1 and 2 emissions and product carbon intensities Use of renewable energy, increased efficiency, and electrification initiatives will lower operating costs and contribute toward reductions of our scope 1 and 2 emissions and product carbon intensities. Additional renewable energy will still be needed in Europe to offset the related grid emissions as will we also need to identify similar outlets in the Americas and Asia Pacific. · By 2030, Avient will obtain directly or contract for 60% of its electricity demand from renewable sources and achieve 100% renewable energy by 2050. · We have established a product carbon footprint team that focuses on providing product-specific carbon footprint metrics based on where and how the product is manufactured. · Our position in enabling the use of recycled materials, bio-renewable solutions, renewable energy, or energy reductions requires manufacturing in a manner and light weighting of transportation vehicles so that they contribute to more efficient value chains and accelerated lower-carbon transitions for our customers. · In 2021, we delivered $915 million in sustainable solutions sales, as defined using critieria aligned with the FTC 2012 Guide for the Use of Environmental Marketing Claims. · We are evaluating our Asia Pacific go-to-market strategy, especially in China. Clean electrification of our operations and processes will represent some of our current scope 1 emissions reductions, though further evaluation is required. · Avient became a member of the RE100 initiative in 2021, committing to achieving 60% renewable energy use by 2030.
