Thank you, Albert, and good morning, everyone. Westlake reported net income of $174 million or $1.34 per share in the first quarter on sales of $3 billion. Net income for the first quarter of 2024 decreased $220 million from the first quarter of 2023. The year-over-year decline in net income was primarily due to lower average sales prices and margins in PEM, particularly in caustic soda, PVC resin, epoxy resin, which were partially offset by improved sales volumes, lower materials costs and lower restructuring costs in HIP.
When compared to the fourth quarter of 2023, net income, excluding identified items, increased by $81 million in the first quarter, primarily due to higher sales volumes driven by an uptick in seasonal demand and strong market growth, for our cost-saving actions and lower restructuring costs.
For the first quarter of 2024, our utilization of the FIFO method of accounting resulted in a favorable pretax impact of $31 million compared to what earnings would have been reported on the LIFO method. This is only an estimate and has not been audited.
Before I discuss the details of our segment results, I want to provide some high-level thoughts on the quarter. The record first quarter results in our HIP segment demonstrate the progress we have made in integrating and optimizing the acquisitions of the last few years. HIP strong 14% year-over-year volume growth in the first quarter in part reflects the benefits of the broad branded product set, combined with a much wider geographical footprint, driving cross-selling of our products through nationwide distributors going into home construction and remodeling.
The record first quarter EBITDA margin of 25% was supported by our cost savings initiatives, production optimization activities and lower materials cost. These cost savings go well beyond typical acquisition synergies as we implement our efficiency-focused manufacturing culture and increased automation within our operations.
Overall, we are very pleased with HIP's asset-light, cash-generative business model and solid EBITDA margin. We hope that you will join us on June 13 as we host a HIP focused investor teaching event in New York to share more about the exciting progress and opportunities we are seeing in this important segment.
Turning to our PEM's segment. Our first quarter results reflect the challenging global industrial and manufacturing macroeconomic environment. That said, we are encouraged by the improving trends for both sales volumes and pricing as we enter the second quarter. We took proactive steps to improve the financial performance of this segment, including progress toward our company-wide $125 million to $150 million cost savings target for 2024 and our efforts to halt the flood of low-priced Asian imports in certain product categories.
Moving to the specifics service segment performance. Our Housing & Infrastructure Products segment produced record first quarter EBITDA of $264 million on $1 billion of sales. EBITDA increased $59 million year-over-year due to a solid 14% increase in sales volumes, improved product mix into higher-margin products, lower materials costs and acquisition synergy and other cost savings benefits.
Notably, HIP achieved an important milestone this quarter with trailing 12-month EBITDA exceeding $1 billion for the first time. This achievement is a testament to the hard work of our HIP colleagues and the synergies achieved across our businesses. When compared to the fourth quarter of 2023, HIP segment sales of $1 billion rose 10% driven by a 12% sequential increase in sales volume, which more than offset a 2% decrease in average sales prices.
Housing product sales of $879 million in the order increased $84 million due to solid sales volume growth, particularly in Pipe & Fittings and Siding & Trim. Infrastructure product sales of $165 million in the first quarter of 2024 increased $14 million from the fourth quarter of '23 due to double-digit sales volume growth in our compounds resin business.
HIP's EBITDA margin of 25% set a record for the first quarter and was the second highest for any quarter. The margin expansion from 20% in the prior year period was primarily due to lower materials cost and higher sales volumes, while the sequential improvement from 18% in the fourth quarter of '23 was due to higher sales volume, improved sales mix and lower restructuring costs as we optimized our manufacturing footprint.
Moving to our PEM's segment. First quarter EBITDA of $253 million was below first quarter of 2023 EBITDA of $615 million due to lower average selling prices, particularly for caustic soda and PVC and epoxy resins.
On a sequential basis, PEM's segment EBITDA of $253 million in the first quarter increased by $52 million from the fourth quarter of 2023 as a result of higher sales volumes, particularly for PVC and epoxy resin, lower feedstock, fuel and power costs and our cost savings actions.
As Albert mentioned, as we entered the second quarter, we are encouraged by the improvement in recent pricing trends and sequential sales volumes growth, reflecting an end of the destocking we experienced in 2023 and reduced competition from low-priced Asian imports in Europe as a result of shipping disruptions in the Red Sea.
Shifting to our balance sheet. As of March 31, 2024, cash and cash equivalents were $3.1 billion and total debt was $4.9 billion, with a staggered long-term rate debt maturity schedule. For the first quarter of 2024, net cash provided by operating activities of $160 million was impacted by an increase in working capital as we grew our inventories and accounts receivable resulting from the seasonal uptick in demand I previously mentioned.
We will continue to look for opportunities to strategically deploy our balance sheet in order to create long-term value. Now let me provide some guidance for your modeling. As we view demand and prices, we continue to expect 2024 revenue in our Housing and Infrastructure Products segment to be between $4 billion and $4.4 billion, with EBITDA margin around 20%.
Westlake continues to execute with financial and operational discipline as we invest throughout the business cycle, and we expect our total capital expenditures to be approximately $1 billion in 2024, which is unchanged from our earlier guidance and is similar to our depreciation and amortization run rate.
As a reminder, this includes cost for planned turnaround of our Petro 1 ethylene unit scheduled to begin in the second half of this year that is projected to last approximately 60 days. We will continue to target the $125 million to $150 million of cost savings in 2024 with roughly $35 million achieved in the first quarter.
For the full year of 2024, we expect our effective tax rate to be approximately 23%, and we expect cash interest expense to be approximately $160 million. Now let me turn the call back over to Albert to provide a current outlook of our business. Albert?
