QuoteFactors to NoteAt the end of fourth-quarter 2020, Caterpillar’s order backlog was $14.2 billion, reflecting a $0.8 billion increase on a sequential basis and $0.5 billion on a year-over-year basis. The manufacturing sector has been recovering from the COVID-19 induced slowdown aided by resumption of the global economic activities and reopening of businesses. For the first quarter, total industrial production rose 2.5% at an annual rate. Also, commodity prices have been improving so far this year. This might have translated into higher order levels for Caterpillar through the quarter. This, along with a stronger backlog and dealer restocking may have benefited Caterpillar’s first-quarter performance.Further, the company has been taking actions to lower costs in the wake of the coronavirus crisis. This, in turn, might have contributed to margins in the quarter to be reported.Segment ExpectationsFor the Machinery, Energy & Transportation segment, which generates around 90% of the company’s total revenues, the Zacks Consensus Estimate for first-quarter 2021 is pegged at $10.4 billion, suggesting an increase of 5% from the prior-year quarter.
