Mark W. Kowlzan
Chairman and Chief Executive Officer at Packaging Co. of America
Thank you, Jamie. Good morning, and thank you all for participating in Packaging Corporation of America's fourth quarter and full year 2022 earnings release conference call.
Again, I'm Mark Kowlzan, Chairman and CEO of PCA. And with me on the call today is Hassfurther, Executive Vice President, who runs our packaging business; and Bob Mundy, our Chief Financial Officer. I'll begin the call with an overview of our fourth quarter and full year results, and then I'm going to be turning the call over to Tom and Bob, who will provide further details. And then, I'll wrap things up and we'd be glad to take questions.
Yesterday, we reported fourth quarter 2022 net income of $212 million or $2.31 per share. Excluding special items, fourth quarter 2022 net income was $215 million or $2.35 per share compared to the fourth quarter of 2021 net income of $262 million or $2.76 per share.
Fourth quarter net income -- fourth quarter net sales were $1.98 billion in 2022 and $2.04 billion in 2021. Total company EBITDA for the fourth quarter, excluding special items, was $409 million in 2022 and $463 million in 2021. Excluding special items, we also reported full-year 2022 earnings of $1.04 billion or $11.14 per share compared to 2021 earnings of $894 million or $9.39 per share. Net sales were $8.5 billion in 2022 and $7.7 billion in 2021. Excluding special items, total company EBITDA in 2022 was $1.9 billion compared to $1.7 billion in 2021.
Fourth quarter and full-year 2022 net income included special items, primarily for certain costs at the Jackson, Alabama mill for paper to containerboard conversion-related activities. Details of all the special items for the year 2022 and 2021 were included in the schedules that accompanied the earnings press release. Excluding special items, the $0.41 per share decrease in fourth quarter 2022 earnings compared to the fourth quarter of 2021 was driven primarily by lower volumes in our Packaging segment, $1.14; and Paper segment, $0.02. We also had higher operating costs of $0.48, primarily from inflation on energy, chemicals, labor and benefits, supplies, repair materials and services and other indirect and fixed costs.
Freight and logistics expenses were unfavorable $0.13, along with higher depreciation expense, $0.09; higher converting costs, $0.06; and higher scheduled maintenance outage expenses of $0.01. These items were partially offset by higher prices and mix in the Packaging segment of $1.18 and Packaging segment -- and Paper segment, rather, of $0.21. A lower share count resulting from share repurchases, $0.08; lower interest expense, $0.04; and a lower tax rate, $0.01. Results were $0.13 above the fourth quarter guidance of $2.22 per share, primarily due to higher prices and mix in the Packaging segment, lower freight and logistics expenses, a lower share count resulting from share repurchases and a lower tax rate.
Looking at our Packaging business. EBITDA, excluding special items, in the fourth quarter of 2022 of $392 million with sales of $1.8 billion resulted in a margin of 21.7% versus last year's EBITDA of $461 million and sales of $1.9 billion, or a 24.5% margin. For the full year 2022, Packaging segment EBITDA, excluding the special items, was $1.8 billion with sales of $7.8 billion or a 23.8% margin compared to full year '21 EBITDA of $1.7 billion with sales of $7.1 billion or a 23.9% margin.
Demand in the Packaging segment was below expectations for the quarter, causing us to run our containerboard system to these lower demand levels. Our employees did a very good job with their cost management and process optimization efforts at these lower production rates to offset the negative volume impact. Total economic-related downtime for the fourth quarter was approximately 231,000 tons. The scheduled maintenance outage and conversion work at our Jackson, Alabama mill was completed successfully during the fourth quarter. And we restarted the mill earlier this month after being down as a result of the lower demand.
The number three machine achieved its first phase design capacity and is producing a very high-quality virgin linerboard. However, based on current containerboard demand levels, we've decided to move the second phase of the conversion work from this spring to next year in 2024.
I'll now turn it over to Tom, who'll provide further details on containerboard sales and the corrugated business.
