Mark W. Kowlzan
Chairman and Chief Executive Officer at Packaging Co. of America
Thank you, Jamie. Good morning, everyone, and thank you all for participating in Packaging Corporation of America's Fourth Quarter and Full-Year 2023 Earnings Release Conference Call.
Again, I'm Mark Kowlzan, Chairman and CEO of PCA. And with me on the call today is Tom Hassfurther, Executive Vice President, who runs the Packaging business; and Bob Mundy, our Chief Financial Officer.
As usual, I will begin the call with an overview of the fourth quarter and full-year results, and then I'll be turning the call over to Tom and Bob who'll provide further details. After they're done, I'll wrap things up and then we'll be glad to take questions.
Yesterday, we reported fourth quarter 2023 net income of $189 million, or $2.10 per share. Excluding special items, fourth quarter 2023 net income was $192 million, or $2.13 per share, compared to the fourth quarter of 2022's net income of $215 million, or $2.35 per share. Fourth quarter net sales were $1.94 billion in 2023 and $1.98 billion in 2022.
Total company EBITDA for the fourth quarter, excluding special items was $394 million in 2023 and $409 million in 2022. Excluding the special items, we also reported full-year 2023 earnings of $784 million, or $8.70 per share, compared to the 2022 earnings of $1.04 billion, or $11.14 per share. Net sales were $7.8 billion in 2023 and $8.5 billion in 2022. Excluding special items, total company EBITDA in 2023 was $1.6 billion compared to the $1.9 billion in 2022.
Fourth quarter and full-year 2023 net income included special items primarily for certain costs at our Jackson, Alabama mill for the paper-to-containerboard conversion-related activities and the closure and other costs related to corrugated products facilities and design center. Details of all special items for the year 2023 and 2022 were included in the schedules that accompanied our earnings press release.
Excluding the special items, the $0.22 per share decrease in fourth quarter 2023 earnings compared to the fourth quarter of 2022 was driven primarily by lower prices and mix of $1.93 in the Packaging segment, lower prices and mix $0.04, and volume $0.03 in the Paper segment and higher depreciation expense $0.10. These items were partially offset by very good volume in the Packaging segment of $1.07 per share. We also had lower operating and converting costs of $0.51, driven by very good process efficiencies and control over other usages of fiber, chemicals, energy, materials and labor, as well as lower energy and wood fiber prices.
In addition, we had lower scheduled maintenance outage expenses of $0.19, lower freight and logistics expenses $0.03, lower other expenses $0.04, and a lower share count resulting from share repurchases $0.04. The results were $0.37 above the fourth quarter guidance of $1.76 per share, primarily due to higher volumes in our Packaging segment, lower operating and converting costs, lower freight and logistics expenses.
Looking at the Packaging business. EBITDA excluding special items in the fourth quarter of 2023 of $385 million with sales of $1.8 billion resulted in a margin of 21.7% versus last year's EBITDA of $392 million and sales of $1.8 billion and also a 21.7% margin. For the full-year 2023, Packaging segment EBITDA, excluding special items was $1.6 billion with sales of $7.1 billion, or 21.8% margin compared to the full-year 2022 EBITDA of $1.8 billion with sales of $7.8 billion, or a 23.8% margin.
Throughout the quarter, demand in the Packaging segment was stronger than our expectations. This higher volume along with the operational benefits of our capital spending program and continued emphasis on cost management and process efficiencies across the entire manufacturing and converting facility system, drove operating and converting costs lower as well.
We had an excellent restart of the Wallula, Washington mill and the number three machine during the latter part of October and ran exceptionally well during the November, December period. And that helped us meet the stronger demand and build some needed inventory during the quarter to ensure that our customers were supplied with their needs.
We plan to restart the number two machine at the Wallula mill in this first quarter to help manage our expectations in the first half of 2024 for continued strong demand, together with scheduled mill maintenance outages and the final phase of the containerboard conversion of the number three machine at our Jackson, Alabama mill.
I'll now turn it over to Tom, who'll provide more details on containerboard sales and the corrugated business.
