MOSAIC CO

Employees

We had 13,249 employees as of December 31, 2025, consisting of approximately 9,914 salaried and 3,335 hourly employees. This includes approximately 719 salaried employees at the Miski Mayo Mine, of which we own 75% and its results are consolidated within our results of operations.

Labor Relations

As of December 31, 2025:

•We had eight collective bargaining agreements with unions covering certain hourly employees in the U.S. and Canada. Of these employees, approximately 51% are covered under agreements that expire in 2026. All are expected to collectively bargain for new contracts in 2026.

•We had agreements with 33 unions covering all employees in Brazil. More than one agreement may govern our relations with each of these unions. In general, the agreements are renewable on an annual basis.

Failure to renew any of our union agreements could result in a strike or labor stoppage that could have a material adverse effect on our operations. However, we have not experienced a significant work stoppage in many years and historically have had good labor relations.

HUMAN CAPITAL

Our employees are the foundation of our Company. Our 13,249 colleagues embody Mosaic’s core principles of responsibility, reliability and future-focus, and are the key to enabling us to execute our mission to help the world grow the food it needs.

As of December 31, 2025, our regular employee base was made up of the following:

Mosaic is committed to the wellbeing and development of our employees, whose collective experiences and perspectives drive innovation, operational excellence and sustained business value.

As part of Mosaic’s strategic priorities, we are committed to a culture of safety, instilling a digital mindset, and collaborating globally to drive enterprise value.

Employee Health and Safety–Safety is a top priority and we strive for zero harm to people and zero environmental incidents. Through the Mosaic Management System, we have established a structured approach to effectively manage and control risk for the safety and wellbeing of our colleagues, the environment and our stockholders. The management system defines processes that help support a safe work environment and establish a continuous improvement cycle to adjust for changing conditions and identified risks.

Global Worker Wellness–Extending beyond safety, our wellness programs are designed to enhance the well-being of our employees – and their families – in the areas of physical and psychological health, and financial security. These programs include health screenings, insurance plans, psychological health training and mental health resources, as well as our Environmental, Health and Safety (“EHS”) Risk Reduction Program, various trainings and flexible schedules. In 2025 we provided additional flexibility to our U.S. employees with regard to their health needs by adding an additional benefits plan option. Likewise, hospitalization insurance was added to the U.S. plans in 2025. Preventative health programs, including step challenges and wellness resources, are also available to employees.

Development–Mosaic believes in continually investing in people and their lifelong learning. Mosaic holds training events throughout the year across all of our locations, invests in leadership competencies through facilitated learning opportunities and hosts an online education platform through Workday Learning, which all employees are encouraged to access for mandatory and self-guided education. Mosaic offers companywide educational reimbursement programs to help employees in each of our operating areas acquire new skills and capabilities to better meet their job responsibilities and provide for future career opportunities within the Company. Mosaic supports membership in numerous professional associations and encourages participation in work-related external networking groups.

•In 2025, Mosaic continued to invest in leadership development programs designed to equip employees with the knowledge and skills needed for the future of our business. These programs address the unique needs of emerging leaders, front-line supervisors, mid-level managers and senior leaders through targeted career-stage development initiatives. Like any company, Mosaic experiences turnover and the need to replace talent related to retirement and succession. Mosaic seeks to minimize unwanted turnover through its talent review, succession management, performance management and compensation processes. We seek to build our talent pipeline through student programs by designing career paths that will enable our employees to grow and evolve their careers at Mosaic.

Community–Mosaic is a thoughtful and engaged neighbor who invests carefully and generously through long-term partnerships with organizations that are making a difference. We are proud to support organizations and initiatives that create growth and leave a lasting impact in our communities in three main focus areas: food, water and local community. In 2024, we invested $16.7 million. While the official 2025 investment data will be available in February 2026, preliminary data indicates continued strong support in these areas with investments of over $15 million. In addition to philanthropic grants and sponsorships of local programs, we also support and facilitate volunteerism by our employees. Similarly, we are active with local committees, boards and associations focused on contributing to the vitality of the people and communities around us.

•2025 was the fifth year of the Mosaic Employee Giving Program (the “Program”) that provides employees with flexibility to connect their personal causes to corporate giving, matching and volunteerism opportunities. The Program aligns to Mosaic’s strategic priorities and our 2025 Environmental, Social and Governance performance goals. Employees can take advantage of Company matching funds through financial contributions, volunteering on personal time, or both. In North America, this can be up to $2,000 annually per employee.

Driving an Inclusive Culture–In 2025, Mosaic continued to make progress in creating a more engaged workforce through our executive-led Employee Inclusion Networks (“EIN”) which are open and available to all employees and by taking action to improve the workplace and employee experience based on insights learned through our 2024 Voice of the Employee survey. Ongoing awareness and education continue to be a cornerstone of Mosaic’s journey to build and promote a more inclusive culture. We continue to focus and expand our recruitment efforts to build awareness and interest in our industry and to attract and retain the best, qualified candidates from a broad variety of sources.

Pay equity is fundamental to our compensation philosophy and our commitment to our employees. Mosaic annually evaluates pay equity and compensation practices to ensure fair and equitable treatment of employees based on our pay-for-performance framework. In 2025, Mosaic engaged an external consultant to conduct our pay equity audit, bringing an independent view of our global pay equity. The results of our 2025 audit revealed .5% outliers, both men and women, who did not have adequate business justifications that will be addressed during our 2026 compensation cycle. Pay equity will continue to be audited every year with periodic external independent reviews to validate our internal observations.

Further information on our human capital practices is available in our sustainability report. Information contained in our sustainability report, or on our website, is not incorporated by reference into, and does not constitute a part of, this Form 10-K.
