Keith Allman
President & Chief Executive Officer at Masco
Thank you, Renee. Good morning, everyone, and thank you for joining us today. Before I get started, I'd like to share with you that we have appointed Robin Zondervan as our incoming Vice President of Investor Relations. Robin is currently our Controller and Chief Accounting Officer and will be transitioning to lead Investor Relations at the end of this month. I have full confidence that with Robin's leadership, we will continue to have a world class Investor Relations function at Masco and provide the investment community with the information and transparency you have come to expect from us.
Now on to our results. I'll start this morning with some brief comments on our fourth quarter and full year results, and I'll finish with our view on 2024 as well as our long-term margin expectations.
Please turn to Slide 5. We delivered a strong finish to another dynamic and successful year. In the fourth quarter, our topline decreased 2% with volumes down across most categories, partially offset by favorable pricing, currency and our acquisition of Sauna360. The smaller decline in volume relative to the first three quarters of the year supports our view that many of our markets appear to be stabilizing.
Operating profit increased $38 million in the quarter due to a favorable price/commodity relationship as we continued to recover the significant inflation that we have experienced over the past two years and due to our continued efforts to drive efficiencies across our operations. Operating profit margin improved 230 basis points to 14.5%. With our strong execution, our earnings per share for the quarter increased 28% to $0.83 per share.
Turning to our segments, Plumbing sales were in line with the prior year in local currency with lower volumes being offset by favorable pricing and our acquisition. Plumbing performance in the quarter was led by Delta Faucet's mid single-digit sales growth driven by strong performance in the wholesale channel. International plumbing performed better than expected in the fourth quarter as demand in Europe and China, while still challenged, appears to be stabilizing. Investments in our leading global plumbing brands, innovative products and customer service are producing results and we will continue to capitalize on these initiatives.
Turning to our Decorative Architectural segment, sales declined 7%, primarily due to a soft DIY paint market, with DIY paint sales declining high single digits. While our PRO paint business declined slightly in the quarter, we are very pleased with our three-year propane stacked comp of approximately 60%. This significant growth in share gain demonstrates the strength of our Behr brand and the quality of our products that continue to resonate with PRO painters. We will continue to invest in this business to expand our services and build upon our successful collaboration with the Home Depot to capitalize on the large opportunity in the PRO paint market.
Now let's review our full year performance. Please turn to Slide 6. Masco executed extremely well in 2023 and improved nearly every operating metric for the full year. Gross margin improved 360 basis points to 35.2%. Operating margin expanded 120 basis points to 16.8%. Plumbing margin expanded 210 basis points to 18%. Decorative margin expanded 10 basis points to 17.8%. Earnings per share grew 2% to $3.86 per share, up from $3.77 per share in 2022.
We delivered a return on invested capital of 36%, and our free cash flow conversion was approximately 122% which allowed us to return $610 million to shareholders in the form of dividends and share repurchases in 2023 and to complete the bolt-on acquisitions of Sauna360 for approximately $136 million. Importantly, we have achieved compound annual earnings per share growth of 14% from 2019 to 2023, delivering on our commitment of double-digit EPS growth through cycles and demonstrating the power of our brands, innovation and portfolio of lower ticket, repair and remodel oriented products. I want to thank all our employees for their strong execution, focus on the customer, and their continuous improvement mindset that deliver this tremendous performance.
Turning to Slide 7. As we look to the future, we are well positioned to achieve strong profitable growth over the next few years through topline growth, market share gains, margin expansion, and disciplined capital deployment.
Our current market assumptions for 2024 are as follows. For the North American repair and remodel market, we expect the market to be flat to down low single-digits. For our international markets, we expect the markets in aggregate to be down low to mid single-digits. For the paint market, we expect the DIY paint market to be down low single-digits and the PRO paint market to increase low single-digits. We expect to outperform the market and for Masco's overall sales to be approximately flat in 2024.
Despite this flat topline assumption, we will continue to improve margins through disciplined pricing, selective cost reductions, innovative product introductions and operational efficiencies across our business. This margin expansion will not be without its challenges. As freight and shipping costs have recently increased, other commodity inputs remain elevated and other costs such as people-related expenses and insurance are increasing. We are up for the challenge and have demonstrated our ability to execute in dynamic times.
We expect to deliver increased plumbing margins of approximately 18.5% and decorative margins of approximately 18% in 2024, resulting in a Masco operating margin of approximately 17%.
Turning to capital allocation, our strategy remains unchanged. Firstly, we will reinvest in our business to maintain and grow our leadership positions and win in the marketplace. This includes continuing to invest in our growth initiatives such as growing our share in the domestic plumbing wholesale channel, continuing to expand our international plumbing share, and continuing to gain share in PRO paint. It also includes investing in our facilities to ensure we have the capacity to support future growth by completing our European faucet and shower facility and our Midwestern paint manufacturing and distribution center.
Secondly, our capital allocation strategy is to maintain a strong investment grade balance sheet with gross debt to EBITDA levels of below 2.5 times. Our balance sheet remains extremely strong with gross debt to EBITDA of 2 times at year end.
Thirdly, we have a targeted dividend payout ratio of 30%. I'm pleased to share that our Board declared a 2% increase in our dividend for 2024, which will bring our annual dividend to $1.16 per share and marks the 11th consecutive annual increase.
And fourth and finally, we expect strong free cash flow conversion in 2024 of approximately 90% and will deploy that free cash flow after dividends to share repurchases or acquisitions. Based on our projected free cash flow, we expect to deploy approximately $600 million to share repurchases or acquisitions in 2024.
Our M&A strategy has not changed. We continue to review and selectively pursue opportunities that have the right strategic fit and the right return for Masco with the goal of adding 1% to 3% topline growth through acquisitions annually. Based on our expected operating performance and capital deployment actions, we anticipate earnings per share for 2024 to be in the range of $4 to $4.25 per share.
Now looking out over the next three years, we will continue our strong execution and deliver margin expansion through 2026. For our Plumbing segment, with our industry-leading brands including Delta and hansgrohe, we expect to expand margins to 20% in 2026, up from 18% in 2023. For our Decorative segment, led by our industry-leading Behr brand, we expect to achieve margins of 19% to 20% in 2026, up from 17.8% in 2023. This would result in overall Masco operating profit margins of approximately 18.5% in 2026. We believe we can achieve these margins with normalized 3% to 5% repair and remodel industry growth in '25 and '26 through leveraging incremental volume, exercising pricing discipline and executing operational improvements.
While 2023 clearly saw a reduction in demand, we believe that our markets will stabilize in 2024 and return to typical growth rates in 2025 and 2026. Structural factors are supportive of increased repair and remodel activity in several ways. Many homeowners have taken advantage of low mortgage rates and are likely to remain in their homes longer. 1.7 million more homes will reach the prime remodeling ages of 20-years-old to 39-years-old over the next three years. And home equity levels remain high. All of these structural forces provide tailwinds for our business and increase our confidence for a strong repair and remodel market. We will continue to invest in our brands, capabilities and people to outperform the competition in both the near and long-term. With favorable fundamentals and our continued focus on executing our growth strategy, together with our strong free cash flow and capital deployment, Masco is well-positioned to continue to drive shareholder value over the long-term.
Now I'll turn the call over to Rick to go over our fourth quarter, full year and 2024 outlook in more detail. Rick?
