We have updated our earnings model to incorporate the likelihood that the virus becomes widespread. Our revised baseline EPS estimates are $165 in 2020 (previously $174) and $175 in 2021 (previously $183), representing 0% and 6% growth. Our reduced forecasts reflect the severe decline in Chinese economic activity in 1Q, lower end-demand for US exporters, supply chain disruption, a slowdown in US economic activity, and elevated uncertainty. Consensus forecasts imply EPS will climb 7% in 2020 and 11% in 2021.
