Caterpillar Inc. announced second-quarter 2021 sales and revenues of $12.9 billion, a 29-percent increase compared with $10.0 billion in the second quarter of 2020. The increase was primarily because of higher sales volume driven by higher end-user demand for equipment and services and the impact from changes in dealer inventories. Dealers decreased their inventories more during the second quarter of 2020 than during the second quarter of 2021.
Operating profit margin was 13.9 percent for the second quarter of 2021, compared with 7.8 percent for the second quarter of 2020. Second-quarter 2021 profit per share was $2.56, compared with $0.84 profit per share in the second quarter of 2020. Adjusted profit per share in the second quarter of 2021 was $2.60, compared with second-quarter 2020 adjusted profit per share of $1.27.
For the first half of 2021, enterprise operating cash flow was $4.0 billion. In total, the company returned $0.8 billion to shareholders in the quarter, after increasing the dividend and reinstating share repurchases. The company ended the period with $10.8 billion of enterprise cash.
"Our dedicated global team remains focused on serving our customers, executing our strategy and investing for future profitable growth," said Caterpillar Chairman and CEO Jim Umpleby. "We're encouraged by higher sales and revenues across all regions and in our three primary segments, which reflect continued improvement in our end markets."
Dealers decreased inventories by $1.4 billion during the second quarter of 2020, compared with a decrease of $400 million during the second quarter of 2021. Favorable currency impacts were related to the Australian dollar, euro and Chinese yuan. Favorable price realization also contributed to the sales improvement.
Sales were higher across all regions and in the three primary segments.
Construction Industries recorded $5.656 billion in revenue in the second quarter of 2021, compared to $4.048 in the second quarter of 2020, a 39.7-percent increase. The Resource Industries division brought in $2.579 billion compared to $1.826 billion in the year-ago quarter, a 41.2-percent jump. The Energy & Transportation segment posted $4.975 billion in Q221 compared to $4.149 billion in Q220, a 16.6-percent hike.
Regarding construction, in North America, sales increased because of higher sales volume and favorable price realization. Higher sales volume was driven by higher end-user demand primarily in residential construction and the impact from changes in dealer inventories. Dealers decreased inventories more during the second quarter of 2020 than during the second quarter of 2021.
Sales increased in Latin America mostly due to higher sales volume driven by higher end-user demand across the region for equipment and aftermarket parts and the impact of changes in dealer inventories. Dealers increased inventories during the second quarter of 2021, compared with a decrease during the second quarter of 2020.
In EAME, sales increased as a result of higher sales volume and favorable currency impacts primarily from a stronger euro. Higher sales volume was driven by higher end-user demand and the impact from changes in dealer inventories. Dealers increased inventories during the second quarter of 2021, compared with a decrease during the second quarter of 2020.
Sales increased in Asia/Pacific primarily due to favorable currency impacts from a stronger Australian dollar and Chinese yuan and favorable price realization, partially offset by lower sales volume. Lower sales volume was driven by lower end-user demand for equipment, primarily in China, partially offset by the impacts from changes in dealer inventories and higher end-user demand for aftermarket parts. Dealers decreased inventories more during the second quarter of 2020 than during the second quarter of 2021.
