Mark W. Kowlzan
Chairman and Chief Executive Officer at Packaging Co. of America
Thank you, Patricia. Good morning, everyone, and thank you all for participating in Packaging Corporation of America's first quarter 2022 earnings release conference call. 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.
I'll begin the call with an overview of the first quarter results, and then I'm going to be turning the call over to Tom and Bob, who'll provide further details. And then I will wrap things up, and we'll be glad to take questions.
Yesterday, we reported first quarter net income of $254 million or $2.70 per share. First quarter net income included special items expenses of $0.02 per share primarily for certain costs at the Jackson, Alabama mill for paper-to-containerboard conversion-related activities. Details of the special items for both the first quarter of 2022 and 2021 were included in the schedules that accompanied our earnings press release. Excluding the special items, first quarter 2022 net income was $256 million or $2.72 per share compared to first quarter 2021 net income of $169 million or $1.77 per share.
First quarter net sales were $2.1 billion in 2022 and $1.8 billion in 2021. Total Company EBITDA for the first quarter, excluding special items, was $467 million in 2022 and $342 million in 2021. Excluding the special items, the $0.95 per share increase in first quarter 2022 earnings compared to the first quarter of 2021 was driven primarily by higher prices and mix of $1.83 and volume of $0.23 in the Packaging segment; higher prices and mix in our Paper segment for $0.15; a lower share count resulting from share repurchases for $0.03; and lower interest expenses of $0.02. These items were partially offset by $0.71 of inflation-related operating cost increases particularly with energy, fiber, chemicals, operating labor and repair labor and materials.
Freight and logistics expenses have now moved higher for seven quarters in a row and were $0.27 per share above the first quarter of 2021 and converting costs were higher by $0.11 per share, driven by labor and materials expenses. We also had higher depreciation expenses of $0.07, lower volume in our Paper segment for $0.06; higher scheduled outage expenses, $0.05; a higher tax rate resulting from some favorable items in last year's tax rate of $0.03; and other costs, $0.01.
The results were $0.22 above our first quarter guidance of $2.50 per share primarily due to higher prices and mix and higher volumes in both our Packaging and Paper segments, operating cost improvements from efficiency and usage initiatives and favorable weather conditions.
Looking at the Packaging business. EBITDA excluding special items in the first quarter of 2022 was $464 million with sales of $1.96 billion, which resulted in a 23.6% margin versus last year's EBITDA of $352 million and sales of $1.62 billion or a 21.7% margin. Demand in the Packaging segment remained very strong as sales volume in both our containerboard mills and our corrugated products plants had record-setting performances. The scheduled maintenance outages in our mills went very well, and both machines at our Jackson, Alabama mill produced containerboard the entire quarter.
However, with strong internal and external demand, we ended the quarter once again with containerboard inventory levels below our targeted and historical levels. Although we still face unprecedented inflationary headwinds in our manufacturing costs as well as freight and logistics expenses, our facilities continue to deliver on numerous cost reduction initiatives, efficiency improvements, integration and optimization enhancements, and capital project benefits to maximize our returns and our margins.
I'll now turn it over to Tom, who will provide further details on the containerboard sales and corrugated products business.
