Timothy M. Knavish
Chairman and Chief Executive Officer at PPG Industries
Thank you, Alex, and good morning, everyone. Welcome to our second quarter 2024 earnings call. I'd like to start by providing a few highlights on our second quarter 2024 financial performance, and then I'll move to our outlook.
The PPG team delivered sales of $4.8 billion and our seventh consecutive quarter of year-over-year segment margin improvement. This culminated in second quarter adjusted earnings per diluted share of $2.50, which is an all-time record for the Company and represents 11% year-over-year growth. Despite increasingly challenging macro-economic conditions, we are building top-line momentum as our underlying year-over-year volume progression improved for the sixth consecutive quarter.
In the second quarter, six of our 10 business units delivered positive volume growth versus prior year, aided by our enterprise growth strategy initiatives. These initiatives, including delivering new products and technologies to our customers, such as our innovative packaging interior can and exterior end-coatings technologies, as well as our new SIGMAGLIDE technology in our marine business. Each of these technologies has allowed us to gain share in their respective businesses. Our actions also include upgrading and modernizing our manufacturing capabilities to drive increased output, such as in aerospace, where demand has outpaced industry supply.
One additional example of our enterprise growth strategy is where we're driving changes to the ecosystem of the business models. This includes in architectural coatings U.S. and Canada with our Home Depot initiative, in our refinish business with our digital tools such as Moonwalk and LINQ, and in our traffic solutions business as we further optimize our service and supply capabilities which are critical value drivers in this business. Additionally, our volume performance in the quarter benefited from our well-established business portfolio in Mexico, China, and India.
Overall, however, our aggregate volumes in the quarter were flat year-over-year, falling shy of our initial expectations, as overall demand in Europe and global auto OEM production were below what we assumed in our second quarter guidance. It is important to note that our European volumes, while still negative, improved sequentially year-over-year versus the first quarter. Also, global industrial activity remains subdued in the quarter.
Consistent with our financial guidance in April, our second quarter automotive refinish sales were down year-over-year, reflecting a strong prior year comparison and lower insurance claims. However, we remain confident that this business will have a strong second-half of 2024.
In the quarter, we drove further margin enhancement and we marked our seventh consecutive quarter of year-over-year segment margin improvement. Our aggregate gross margin was 43% for the quarter, a 180 basis-point improvement year-over-year. Our Performance Coatings segment achieved all-time record segment margin of 18.7%. And our Industrial Coatings segment also improved its margin profile by 120 basis points versus the prior year.
During the second quarter, we benefited from stable upstream and downstream supply chains. And the vast majority of our suppliers have sufficient or excess capacity, which is noteworthy as this occurred during the peak season for raw material consumption. Consistent with our guidance, we experienced mid-single-digit percentage raw material deflation that we expect will normalize into flat to low-single-digit deflation for the third quarter, as we anniversary prior year impacts. This benefit was partially offset in our results by general inflation, including higher year-over-year wages and employee benefits.
We are proud to have published our 2023 ESG Report in the quarter, which highlighted progress against our 2030 targets, including increasing sales from sustainably advantaged products and reducing greenhouse gas emissions throughout our own operations and our value chain.
I want to take this opportunity to provide you with an update on our previously announced strategic reviews of the architectural coatings U.S. and Canada business and the global silicas product business. We make good progress with these processes and are pleased to have a number of engaged and interested parties. We're working through the traditional bidding, management presentation and data provision stages, and remain on our original schedule to determine a path forward for each of these assessments. We have also made further progress in driving improvement in working capital, including lowering our year-over-year inventories during the quarter. As a result, our operating working capital was down 90 basis points year-over-year. We have more work to do over the balance of the year as we move towards seasonally slower sales quarters, but we have already returned to near pre-pandemic inventory levels.
We ended the quarter with a strong balance sheet and remain committed to deploy excess cash for shareholder value-creation. During the quarter, we repurchased $150 million of PPG shares, bringing our year-to-date total to about $300 million. This is on top of our fourth quarter 2023 repurchases. Also, yesterday, consistent with our long heritage, our Board authorized a $0.03 dividend increase from $0.65 to $0.68 per share.
Now, looking ahead to the third quarter, we expect overall organic sales a flat to low-single-digit percentage growth. In Mexico, we expect to again deliver excellent financial results. We also believe that demand in China will deliver organic growth, as a result of our technology-advantaged products, but albeit at a lower growth rate than achieved in the first-half of the year. In Europe, demand remains uneven by country and end-use, but we expect modest sequential year-over-year improvement. In addition to those businesses that grew in the second quarter, we expect organic growth in automotive refinish coatings and protective and marine coatings. And also, while slightly unfavorable year-over-year, we are expecting projecting modest sequential quarterly improvement in general industrial demand.
We expect to deliver adjusted third quarter EPS between $2.10 and $2.20 per share, aided by solid operating performance. Our guidance mid-point is 4% higher than our record third quarter 2023. However, the mid-point of our guidance is 10% higher than the third quarter of '23 excluding the impact of a higher year-over-year tax rate as the prior year included several non-recurring favorable discrete tax items. The difference in the tax rate is reducing our year-over-year EPS comparison by approximately $0.12 at the mid-point.
We anticipate overall Company selling prices to be flat in the third quarter, as the impact of certain index-based customer contracts in our Industrial Coatings segment will be offset by selling price increases in our Performance Coatings segment, including some additional incremental pricing that will be realized in the third quarter.
With regard to commodity raw materials, supply remains ample, and we continue to realize benefits from moderating input costs. In the third quarter, we expect flat to low-single-digit percentage raw material deflation, lower than the second quarter, as we anniversary some decrease realized in 2023. As we have consistently demonstrated, we will further -- we will drive further improvement of our operating margins, aided by sales volume growth leverage as a result of the execution of our enterprise growth strategy and self-help in manufacturing productivity and cost control initiatives, which includes continued execution of our previously approved restructuring actions.
Our more than 50,000 employees are committed to delivering best-in-class solutions to our customers that will drive growth for PPG. Our results this quarter were made possible by our highly dedicated team around the world who make it happen and deliver on our purpose to protect and beautify the world every day. Thank you for your continued confidence in PPG.
This concludes our prepared remarks. And now, would you please open the line for questions?
