We are committed to mitigating the impact that our products and operations may have on the environment. We are not a metals producer or mill – we operate metals service centers. As a distributor and “first-stage” processor of metal products, our operations, by their nature, have a limited environmental impact as we do not emit significant amounts of carbon dioxide or other greenhouse gases.

In addition, the overwhelming majority of our operations involve the distribution and processing of inherently sustainable steel and aluminum products that are (i) are some of the most commonly-recycled materials in the United States and (ii) can be 100% recycled without loss of quality. We believe steel, one of our most significant products, is the most recycled material on the planet – more than plastic, paper, and glass combined each year. In 2021, we reintroduced over 193,000 tons of recycled scrap material into the manufacturing life cycle.

We continue to evaluate and implement energy conservation and other initiatives to reduce the environmental impact of our business.

As a processor and distributor of metals, and not a producer, we acknowledge and embrace our role in protecting the environment and are currently assessing our impacts. Our strong desire is to identify and prioritize areas of improvement. In order to align our environmental initiatives with our broader strategy, we completed a materiality assessment in 2021 to determine the environmental matters that are most critical to our business and our stakeholders.

As a result of the materiality assessment, we determined that the most material environmental issues are: (i) emissions from company-owned trucks that deliver our products; and (ii) our overall energy usage. We expect to update this materiality assessment on a periodic basis to ensure it reflects changes in our business and the external environment. We continue to analyze the detail of our direct emissions (Scope 1 and 2) across the majority of our facilities. We look forward to communicating our progress over time as we continue to maintain focus on ESG matters.

Sell scrap material generated in our operations to recyclers

• 193,000 tons of recycled scrap material were reintroduced into the manufacturing life cycle by the Reliance Family of Companies in 2021

Scope 1 emissions⁽¹⁾ represent direct greenhouse gas (GHG) emissions resulting from fuel consumed to operate our trucking fleet and facility operations. As a distributor, approximately 75% of our Scope 1 emissions arise from fuel consumption for product delivery. Scope 1 (GHG) emissions for our fleet of ~1,720 trucks, ~315 locations and 36.4 million square feet of owned and leased facility square footage:

• 2021: 180,000 metric tons
• 2020: 173,000 metric tons
• 2019: 187,000 metric tons

Scope 2 emissions⁽²⁾ represent indirect GHG emissions from purchased electricity. Emissions at each facility vary based on amount of energy purchased and emissions efficiency of grid energy source. Scope 2 emissions across our ~315 locations:

• 2021: 100,000 metric tons
• 2020: 99,000 metric tons
• 2019: 111,000 metric tons

Emissions intensity represents emissions efficiency on a sales or volume basis⁽³⁾:

• 2021: Sales – 19.9 metric tons/$M, Volume – 22.9 metric tons/thousand tons
• 2020: Sales – 30.9 metric tons/$M, Volume – 24.8 metric tons/thousand tons
• 2019: Sales – 27.2 metric tons/$M, Volume – 23.5 metric tons/thousand tons

^{(1) Scope 1 emissions, in mt CO2e, are calculated based on fuel usage and United States Environmental Protection Agency’s April 2021 fuel emissions factors.
(2) Scope 2 emissions, in mt CO2e, are calculated by applying latest eGrid emissions factors to purchased electricity.
(3) Sales intensity, reported as mt CO2e/$M net sales and volume intensity, reported at mt CO2e/K tons sold and tons toll processed.}

Safety performance updates:

• Total Recordable Incident Rate (TRIR)
• 2021: 2.12
• 2020: 1.86
• 2019: 2.43
• 2018: 2.86
• Reliance’s TRIR is significantly lower than the 2020 Metals Service Center Institute average of 3.5
• Average USDOT Recordable Accident Rate⁽¹⁾
• 2021: 0.54
• 2020: 0.60
• 2019: 0.75
• 2018: 0.78

^{(1) Currently, there is no universally accepted and annually updated benchmarking standard for a DOT recordable crash rate.}
