Sustainability 2019 Table of Contents 03 Environment 10 Community 14 Food 16 Animal Welfare 19 People & Workplace 22 Appendix As the largest producer and marketer of shell eggs in the United States, we at Cal-Maine Foods take seriously our position in the marketplace and the opportunity we have to advance the sustainability of shell egg production. Our eggs are an important source of low-cost protein, vitamins and minerals for millions of families and providing healthy eggs to families in a responsible and sustainable manner has always been our goal. We have shared our mission to be the most sustainable producer and reliable supplier of consistent, high-quality fresh shell eggs and egg products in the country and we are excited to update you on our progress and what that means at Cal-Maine Foods. Dolph Baker Chairman of the Board and Chief Executive Officer The food industry as a whole, and especially the egg market, is experiencing continuing transformation as consumer and customer preferences change. The current landscape requires balancing a range of topics including food safety and affordability, animal welfare, responsible management of land, air and water and ultimately a commitment to the communities in which we operate. We embrace this opportunity and obligation to engage with our customers, consumers, employees and communities to demonstrate a “Culture of Sustainability” in everything we do. As customers’ and consumers’ product preferences continue to evolve, and the regulatory framework around egg production continues to shift, we will continue our efforts to increase transparency. We believe it is incumbent on Cal-Maine Foods to provide information to our stakeholders regarding our efforts to minimize the impact of our business on the environment, our rigorous food safety and quality processes, our programs to promote the health and safety of our flocks, our community engagement, our efforts to provide our employees with a safe and healthful place to work and our other efforts to drive sustainability across our value chain. We also hope to educate our stakeholders on some of the trade-offs between production practices and environmental inputs and outputs. We are proud of our efforts and advancements in recent years to reduce the energy and resource inputs for our egg production and to improve our stewardship of natural resources. We are equally proud to be good corporate citizens where we operate, helping contribute to healthy, prosperous communities. We make it a priority to create job opportunities, support volunteer outreach efforts, donate healthy food, support agricultural education programs and make other positive contributions to local economies. We are in the process of evaluating and setting targets and goals for our ongoing sustainability initiatives. We look forward to keeping you apprised of our continued efforts to improve sustainable egg production and of our achievements as we work to fulfill our mission.

On average, these installations reduce energy consumption by 10% and reduce greenhouse gas emissions. We will continue this effort to lead to even greater reductions in the future. • We implemented seven boiler, furnace and heater upgrades to reduce greenhouse gas emissions by 176 tons per year. New additions and replacements will further reduce emissions1. • We invested $4.8 million performing general processing equipment updates to reduce greenhouse gas emissions by 90 tons/year. • We domestically source 100% of the soy meal and corn purchased to manufacture feed. • Through effective management and advancements in our feed program, we have reduced the phosphorus generated by our operations by 50%, or by 2.7 million pounds, in 2018, compared to 2016. Reduced Energy Consumption In 2016, we began converting our facilities to operate with energy efficient LED lighting as we journey on the path to reducing our carbon footprint. On average, these installations have reduced energy consumption by about 10% per facility. We have also upgraded boilers, furnaces, heaters and other equipment across many of our facilities; all contributing to reduced energy consumption and greenhouse gas emissions. Going forward, we will continue upgrading our facilities and evaluating other technologies and investments to decrease our energy consumption and emissions even further. Greenhouse Gas Emissions in Egg Production It is important to our company that we drive change to reduce energy consumption and the associated emissions that are within our control.

We have learned that over 70% of the lifecycle greenhouse gas emissions related to egg production are attributable to upstream feed-related emissions, i.e. the growing, harvesting, storing and transporting of corn and soybeans by farmers and others who supply these main ingredients to us for our production of feed. 1990 Baseline 2,772 kg CO2e / 1000 kg eggs 2016 Study 1,600 kg CO2e / 1000 kg eggs 62% Feed 22% Housing & Manure 77% Feed 5% Housing & Manure 2% Energy Use in Facilities 1% Manure Export & Application 13% Pullet Production 6% Energy Use in Facilities 12% Pullet Production Source: Blonk Consultants Trend Study of Dutch animal production layers (chapter layers) The charts above illustrate the progress that has been made by the egg experts to reduce greenhouse gas emissions, represented in the charts as CO2e and their impact on the climate through more efficient feed and production practices – resulting in a 42% reduction of greenhouse gas emissions as compared to baseline practices. While this data is from a European study, we believe it is reflective of similar emissions breakdown trends in United States egg production. We are working with industry experts to support a lifecycle study and analysis here in the United States to give us a better understanding and perspective on reducing emissions at our locations. Greenhouse Gas Emissions from Our Operations We are studying and have estimated the greenhouse gas emissions from our direct operations, and we intend to set Scope 1 and Scope 2 greenhouse gas emission reduction targets, in addition to setting science-based targets, which will support our efforts to reduce our energy consumption and greenhouse gas emissions. At the same time, it has been widely reported that the overall trend in egg production is shifting towards more cage-free housing in response to changes in the demands of customers and consumers and resulting changes in certain state laws require that only cage- free eggs be sold in the state. However, cage-free housing involves trade-offs. For example, research conducted by the Coalition for Sustainable Egg Supply1 has shown that cage-free production tends to increase climate change impacts in the following ways: • Cage-free production generally requires the use of more natural resources and has greater environmental impacts; • Cage-free production decreases the efficiency of laying hens and causes more feed waste. This research states that, “The cage-free aviary house may need supplemental heat during cold days and when coupled with lower cage-free aviary feed efficiency, creates a larger carbon footprint than enriched colony or conventional cage, as feed supply accounts for approximately 80% of total carbon footprint in the egg supply chain.”1 This research also shows that, “more natural resources are needed per bird space in the construction of cage-free aviary houses.” We are seeking direction from our customers and other stakeholders as decisions are made around future production, and will continue our efforts to optimize efficiencies in our operations while minimizing the impact on the environment no matter what systems are utilized.

The egg industry has been progressive in adopting innovative packaging other beneficial purposes. Manure from our farms is typically sold to neighboring farmers for their use on growing crops, materials that balance food safety, product protection, consumer convenience and and we apply most of the wastewater generated on our farms to growing forage crops that are used by others to feed environmental impact. From retail egg cartons to bulk wholesale packaging, Cal-Maine Foods livestock. In fact, we have found that farmers often prefer the renewable poultry nutrients we offer to commercial or has worked to remain responsive to customer needs while incorporating environmentally other fertilizers due to the comparatively high levels of organic nutrients and micronutrients. Our farms typically operate under federal and/or state permits that require certain minimum standards, monitoring, record keeping and reporting. We take this responsibility seriously and employ industry leading programs, nutrient management plans and practices that aim to optimize nutrient use, crop yields and crop quality, all while reducing the potential impacts to the environment. We regularly train our employees to be accountable to our programs and help ensure the proper handling, storage and use of all manure and other wastes generated by our operations. Modern technologies are also creating value for manure in applications such as renewable biofuels and more effective and efficient fertilizers and soil amendments. Cal-Maine Foods is exploring these technologies and other options to help us more efficiently use and recycle manure and other wastes to help protect the environment, reduce greenhouse gases and potentially add incremental value to our company. preferable packaging when possible. While most of our eggs are packaged in customer specified cartons, we have also worked with our suppliers to be sure that all corrugated materials come from forestry tracts that are third party certified as sustainable by the Sustainable Forestry Initiative1. Compared to 1960, today it takes % 32 Less water to 1 dozen eggs The volume of water conserved would fill 3,700 olympic-sized swimming pools. Source: American Egg Board 1 Water Resources According to a study by the Egg Industry Center at Iowa State University, today each dozen eggs produced requires 32% less water than the typical practice from the 1960s. Increases in water efficiency have come from advancements in crop quality, watering infrastructure in hen houses and best management practices in cleaning and processing. Compared to 1960, this study indicates that water savings across the egg industry each year is approximately 2.4 billion gallons, or enough to fill more than 3,700 Olympic sized swimming pools. Cal-Maine Foods was an early mover in the utilization of advanced metering systems for process inputs that have been installed at most of our facilities. These systems measure our three operational uses for water (evaporative cooling, egg washing and water for the chickens) and are able to detect leaks or other issues early to conserve resources. We are studying strategies and available technologies to help us better understand and manage our water resources. Cal-Maine Foods has been a leader in the use of modern, reusable plastic containers (RPCs) for packing egg cartons for shipment. We provide RPCs as a more sustainable packing option for our customers because they reduce corrugated cardboard container waste in our supply chain. Although more expensive, RPCs not only help us reduce the amount of corrugated cardboard we use but also provide better protection during transport and have better ventilation than traditional packaging which allows freshly packed eggs to cool more quickly. These design features also result in fewer damaged eggs and less food waste. In 2018, we were able to utilize 35.5% RPCs and similar (reusable) basket packaging options in our supply chain, reducing the greenhouse gases associated with corrugated cardboard by 38,789.83 million tons. Corrugated Cardboard Facts • The Environmental Protection Agency (EPA) estimates 30.1 million tons of corrugated cardboard are generated each year. • Cardboard is the third largest disposed-of product by weight. • Cardboard is also the second largest item in landfills by volume. • Cal-Maine Foods uses RPCs when possible to replace corrugated cardboard in our supply chain to reduce waste and greenhouse gas emissions. 1 https://www.aeb.org/images/PDFs/FoodManufacturers/WP-sustainability.pdf 1 https://www.sfiprogram.org/ Sustainability 2019 Cal-Maine Foods, Inc | 08 Sustainability 2019 Cal-Maine Foods, Inc | 09 Nutrient & Land Management Our flocks naturally produce manure and wastewater that contain valuable nutrients (nitrogen, phosphorus and other Sustainable Packaging Food packaging constitutes one of the largest challenges – and opportunities – in waste micronutrients) that have been used throughout history as a renewable fertilizer, soil amendment and for energy and management.

Since 2001, Step Up has awarded more than 784,000 Florida Tax Credit scholarships due in part to corporations like Cal-Maine Foods that fund them with tax-credited donations. This is the first year that Cal-Maine Foods has partnered with Step Up For Students and its donation funded the scholarships of 14 deserving K-12 children. Community Engagement Highlights • Leading educational opportunities for local 4-H groups and FFA (formely, the Future Farmers of America) chapters through national scholarships. • Participation in local workforce development and job fairs. • Employee volunteerism with local non-profits, community groups and churches.

Community Engagement & Volunteering Cal-Maine Foods owns and operates 44 locations in 15 states across the United States. Our presence in these communities – mostly rural communities across America’s heartland – is often that of a significant employer and Hurricane Harvey Relief In August of 2017, Hurricane Harvey made landfall in south-central Texas, near the Boiling, Texas, Cal-Maine Foods facility. This category 4 hurricane affected the surrounding communities as well as several employees and their families. Our employees, who were at the core of this effort, immediately mobilized and put a fundraising campaign in place. Thanks to our employees’ culture of philanthropy instilled throughout Cal-Maine Foods, truckloads of food, water and clothing were given out to community members in need. There is a tremendous need for food in disasters like this devastating hurricane. As egg farmers, Cal-Maine Foods is in a unique position to help feed people. Thanks to the efforts of our employees, we were able to get our product into the hands of people who needed it. Early in the disaster, conditions made it quite difficult to manage fresh eggs in the shell, corporate citizen. We take our role as a corporate citizen seriously by working with and in our local communities in ways but with some innovation, we found ways to provide eggs for people. Whether it was scrambled eggs in a bag, hard- boiled eggs, liquid eggs, or protein packs, Cal-Maine Foods distributed more than 27 pallets of product. that enrich the quality of life and create thriving communities. Our partnerships with local agricultural education groups, such as 4-H1 and FFA2 chapters, provide us an opportunity to use our experience and scale in the agricultural industry to teach young people about the opportunities available in farming and food production careers. We feel that these programs and partnerships are vital, both to supporting young people as well as creating the farmers and food producers of tomorrow. Flooding and Disaster Relief The employees of Cal-Maine Foods, along with various of its vendors, united for the “Cal-Maine Strong” fundraiser for the first time in August 2016, following a three-day, slow moving rainstorm that hit South Louisiana and affected several Cal-Maine Foods’ employees and their families. The fundraiser’s sole goal was to “help our Cal-Maine Family.” Shortly thereafter, many more Cal-Maine Foods employees and their families were affected by Hurricane Harvey in Texas and Hurricane Irma in Florida. Again, the “Cal-Maine Family” united to raise over $180,000 for our employees devastated by these natural disasters. Some of the same employees who supported Louisiana the year before were now in need of aid and the “Cal-Maine Family” was quick to provide. Deborah Campbell, one of our compliance managers, stated, “When I go to different locations and see employees still wearing the Cal-Maine Strong shirts, I am reminded that Cal-Maine Foods is one really big family ready to help each other.” Cal-Maine Foods has since expanded this program and now dedicates approximately $50,000 per year to the cause for use in future disasters and employee needs. 1 https://4-h.org/ 2 https://www.ffa.org/ Sustainability 2019 Cal-Maine Foods, Inc | 12 Sustainability 2019 Cal-Maine Foods, Inc | 13 Step Up For Students In December of 2019, Cal-Maine Foods also donated $100,000 to Florida’s Step Up For Students Scholarship Program.

Absence of Artificial Hormones Cal-Maine Foods does not use artificial hormones in the production of its eggs. Hormone use in the poultry and egg production industry has been effectively banned in the United States since the 1950s. Use of Antibiotics Cal-Maine Foods has an extensive written protocol that only allows the use of Medically Important Antibiotics when animal health is at risk, consistent with guidance from the FDA and the Guidance for Judicious Therapeutic Use of Antimicrobials in Poultry, developed by the American Association of Avian Pathologists.

Our programs are designed to ensure that antibiotics are ordered and used only when necessary and records of their usage – when and where – are maintained in order to monitor compliance with our protocols. Cal-Maine Foods does not use antibiotics for growth promotion or performance enhancement. Within the 2018 reporting year, use of feed containing antibiotics as a proportion of our overall feedstock represented just 0.5% of annual totals. Organic Production All of our Organic eggs are certified by the USDA and a third-party Organic certifier. In order to be certified to this standard, organic eggs must come from chickens that are raised cage-free, fed an organic diet grown without pesticides, managed without antibiotics and hormones and have access to the outdoors as required by the National Organic Program. Animal Welfare Animal Welfare Program at Cal-Maine Foods Animal welfare is of utmost importance to Cal-Maine Foods.
