Timothy M. Knavish
Chairman and Chief Executive Officer at PPG Industries
Thank you, Jonathan, and congratulations on your new role. And good morning, everyone. Welcome to our fourth quarter and full year 2023 earnings call. I'd like to start by providing a few highlights on our fourth quarter and full year 2023 financial performance, and then I will move to our outlook. In the fourth quarter, the PPG team delivered strong financial results, including record fourth quarter sales of $4.4 billion and adjusted earnings per diluted share of $1.53. This is our fourth consecutive quarter of delivering record sales as we continue to benefit from organic sales growth. Our fourth quarter adjusted EPS was 25% higher year-over-year, driven by aggregated segment margin improvement of 260 basis points compared to the fourth quarter of 2022, as we continue to be laser-focused on driving margin improvement. Our results reflect our continuing growth trends and strong execution in several of our leading and technology-advantage businesses, which culminated in record fourth quarter sales in the aerospace, automotive OEM, automotive refinish businesses with strong performance in the protective and marine and PPG Mexico architectural coatings businesses.
Our year-over-year sales volume trend improved compared to recent quarters, decreasing less than 1% year over year. We continued to experience lower global industrial production along with soft U.S. and European architectural demand, especially for DIY-related products. Notable for us during the quarter was China, where despite a lethargic general economy, we achieved high-single-digit percentage volume growth, reflecting our strong mix of businesses in the country. In addition, we delivered flat year-over-year volumes in Europe as we see economic stabilization in the region, albeit at lower absolute demand levels.
Our selling prices were about 2% higher with both segments delivering positive price, led by the Performance Coatings segment. We expect total company selling prices to remain modestly positive in the first quarter of 2024 as new selling price increases have been implemented in several of our businesses. We also benefited from further normalization of our operations as we experienced stabilization of both upstream and downstream supply chains and order patterns. From a supply perspective, the vast majority of our suppliers have more than sufficient capacity heading into 2024. We started the year laser focused on margin recovery and the fourth quarter marked our fifth consecutive quarter of year-over-year operating segment margin improvement. As I mentioned, fourth quarter aggregate segment operating margins increased 260 basis points year-over-year and full year increased 310 basis points.
We also achieved our second key priority for the year by delivering excellent cash generation of nearly $900 million during the fourth quarter, which was up over $300 million on a year-over-year basis, leading to record full year cash generation of over $2.4 billion. We significantly reduced working capital by a total of about $600 million on a sequential quarterly basis. This includes the benefit from a partial reduction of our inventory levels. However, we still ended the year with higher inventory levels from a historical perspective, primarily in raw materials, and we'll continue to reduce inventory in the first half of 2024. The strong cash generated drove a reduction in net interest expense by about $20 million compared to the fourth quarter of 2022 as we repaid some high variable cost debt during the quarter. Additionally, we repurchased $100 million of stock in the fourth quarter, which essentially offset dilution.
Now, a few comments on the full year 2023. As we communicated at the beginning of 2023, my priorities included margin recovery, strong cash generation, and further strengthening of our capabilities to support our customers' productivity and sustainability needs, which will result in higher PPG organic growth. Coming into 2023, we had a high degree of conviction that our global business portfolio would prove resilient while anticipating a challenging economic environment and these clearly played out during the year.
For the full year, I'm proud of our team's execution against our strategic objectives as it resulted in delivery of record sales, record adjusted EPS, and record operating cash flow. And our sales performance was led by continued selling price execution to offset significant multi-year cost inflation. Our year-over-year earnings growth was driven by these improved selling prices, coupled with moderating input costs and cost structure reductions stemming from our cost management and restructuring initiatives. This resulted in improved margins in both segments.
Our businesses delivered innovative and value-added products and solutions to our customers and this enabled several of our businesses to set all-time annual sales records, including our aerospace, auto OEM, automotive refinish, architectural Mexico, and the protective and marine coatings businesses. Our enterprise growth initiatives delivered about $150 million of incremental sales in the first year, including strong growth from selling our innovative products for electric vehicles as well as our share gains in powder coatings. In automotive refinish, customer adoption of our industry-leading digital tools accelerated, yielding nearly 2,000 net body shop wins. These digital tools include our LINQ services and MOONWALK mixing machines, both of which are best-in-class and are focused on improving body shop productivity. In Mexico, we further advanced cross-selling of our valued products, including protective coatings and certain light industrial coatings through the best-in-class distribution network of nearly 5,200 concessionaire locations. Finally, our strong focus on the customer drove share gains across several businesses, including expansion of our architectural coatings products at Walmart.
Strategically, we conducted an ongoing review of both our product and business portfolios, leading to the divestiture of several noncore assets, including our European and Australian traffic solution businesses, along with the recently announced strategic alternatives review of the silicas products business. In a variety of cases, we also simplified and improved our product offering, allowing us to reduce complexity and drive down working capital. Finally, these actions plus strong balance sheet management resulted in record full year 2023 cash generation of $2.4 billion.
So overall we achieved excellent financial results in 2023 and are anticipating improving from this higher base in 2024. We remain confident that we will deliver positive sales volume in 2024, including benefits from China, India, and Mexico. We've delivered share gains in several businesses, including auto refinish, packaging, and protective and marine coatings businesses. We will also execute on our more than $250 million order backlog in aerospace, drive further growth in our well-positioned businesses in Mexico, and further expand the benefits of our key growth initiatives, including powder coatings, electric vehicle products, and digital solutions.
We will drive further improvement of our operating margins, aided by the sales volume growth leverage and our initiatives to drive manufacturing productivity following several years of supply chain and other disruptions. Lastly, we entered 2024 with a strong balance sheet, which provides us with the flexibility for further shareholder value creation going forward, including funding organic growth initiatives, appropriate acquisitions, debt repayment, and share repurchases.
Now I'll comment on our first quarter outlook. We expect to deliver sequential adjusted EPS growth from $1.53 per share in Q4 2023 to a range of $1.80 to $1.87 per share in Q1 of 2024, an increase of 20% at the midpoint of the range. We anticipate global industrial production to remain soft and our year-over-year sales volume performance will be unfavorably impacted by the approximate $40 million non-recurring Walmart customer load-in that occurred in the first quarter of 2023. Also, the timing of the Easter holiday will shift some sales into the second quarter.
Despite these difficult year-over-year comparison items, we expect our first quarter sales volume will be flat overall, aided by positive sales volume growth in our aerospace, protective and marine, and packaging coatings businesses. We project solid growth in our auto OEM business in Asia Pacific where we expect to drive solid volume growth in China, led by our strong positioning with the electric vehicle OEM producers. Additionally, we expect to deliver organic sales growth through our best-in-class Mexico distribution platform. We anticipate overall company selling prices to remain positive as some modest declines in our industrial reporting segment related to a small portion of customer-based index contracts will be more than offset by targeted selling price increases in our performance coatings segment.
First quarter comparisons also include declines in certain transitory European energy-related pricing indices that were put in place during the period of extremely high energy prices in the region. These particular price declines are offset by lower purchased energy costs for our facilities. The net selling price increases, along with various productivity initiatives, will serve to offset somewhat higher expected wage inflation in 2024, especially in emerging regions.
With regard to commodity raw materials, supply remains ample, and we will continue to realize benefits from moderating input costs, including further recognition of savings stemming from working down our higher inventories as we progress through 2024. We will diligently manage our costs and expect to deliver manufacturing and productivity gains supported by a more stable supply chain and customer order patterns. We anticipate more moderate year-over-year earnings growth in the first quarter associated with some of the transitory items I mentioned earlier. However, we are confident that we will deliver our commitment for full year earnings growth of around 10% at our forecast guidance midpoint.
Finally, I want to thank our more than 50,000 employees for making it happen by delivering excellent 2023 financial results and positioning the company for growth and value creation in 2024 and beyond for the benefit of all stakeholders.
Thank you for your continued confidence in PPG, and this concludes our prepared marks. And now would you please open the line for questions?
