Item 8.01. Other Events.

3M Company (3M or the Company) is filing this Current Report on Form 8-K to supplement and update the risk factors that were previously described in Item 1A of 3M’s Annual Report on Form 10-K for the year ended December 31, 2019.

The Company is subject to risks related to public health crises such as the global pandemic associated with the coronavirus (COVID-19).

3M, as a global company, is impacted by public health crises such as the global pandemic associated with COVID-19. The outbreak has significantly increased economic and demand uncertainty. In addition, public and private sector policies and initiatives to reduce the transmission of COVID-19, such as the imposition of travel restrictions and the adoption of remote working, have impacted 3M’s operations. In these challenging and dynamic circumstances, 3M is working to protect its employees and the public, maintain business continuity and sustain its operations, including ensuring the safety and protection of about 50,000 people who work in our plants and distribution centers across the world, many of whom support the manufacturing and delivery of products that are critical in response to the global pandemic. COVID-19 may impact 3M’s supply chains relative to global demand for products like respirators, surgical masks and commercial cleaning solutions. COVID-19 may also affect the ability of suppliers and vendors to provide products and services to 3M. Some of these factors could increase the demand for 3M products, while others could decrease demand or make it more difficult for 3M to serve customers. Furthermore, COVID-19 has impacted and may further impact the broader economies of affected countries, including negatively impacting economic growth, the proper functioning of financial and capital markets, foreign currency exchange rates, and interest rates. For example, in recent weeks, the continued spread of COVID-19 has led to disruption and volatility in the global capital markets, which increases the cost of capital and adversely impacts access to capital. Due to the speed with which the situation is developing and the uncertainty of its duration and the timing of recovery, 3M is not able at this time to predict the extent to which the COVID-19 pandemic may have a material effect on its financial or operational results.
