Response

Oshkosh Corporation manufactures products that rely on critical materials to ensure quality, performance, durability and longevity of our vehicle offerings. Through cooperation of our global supply chain partners, we expect suppliers to adhere to ethical conduct, human rights, safety, quality and environmental sustainability standards. We utilize different tools and strategies to be socially responsible and understand the reputation of Oshkosh Corporation and its products may be impacted by the supply, price and regulation of these materials, including conflict minerals. Oshkosh Corporation's global supply chain partners are vetted through a series of controls to better understand how our partners determine and ensure traceability of content throughout the product life cycle; some of these controls include quality audits and operational assessments. In addition, Oshkosh Corporation mitigates risk through the use of our Supplier Code of Ethics and Conduct, Supplier Standards Guide, Country of Origin processes and multi-tier analysis of our global supply chain.

Oshkosh Corporation's Supplier Code of Ethics and Conduct requires Tier 1 suppliers to adhere to the following policies regarding conflict minerals:

• Inquiries about the country of origin of products, containing 3TG materials, delivered to any Oshkosh Corporation facility, whether sourced directly or through a sub-supplier.
• Conduct due diligence to verify 3TG materials were sourced from a conflict-free source.
• Disclose evidence of due diligence to Oshkosh Corporation.

We have established our goal of 100% compliance with the Oshkosh Supplier Code of Ethics and Conduct, Supplier Standards guide and our Terms and Conditions of our global supply chain, directly or through sub- suppliers. Critical materials may experience price volatility in response to supply and demand. We promote resource efficiency and environmental stewardship, and we expect the same throughout our supply chain. As outlined in our Supplier Code of Conduct, we require Business Partners to follow all environmental laws, policies and procedures that apply to their business. Oshkosh Corporation ensures we source product and materials ethically by utilizing controls to partner with our global supply chain to identify and oversee the use of critical materials.
