As a quick reminder, on the basis of presentation for our third quarter financial results, our total company net sales, operating EBITDA, and adjusted EPS include segment results for Electronics Co. Earlier today, we reported another solid quarter ahead of our previously communicated guidance. Third quarter sales of $3.1 billion grew 6% on an organic basis. Operating EBITDA of $840 million increased 6% year-over-year, resulting in an operating EBITDA margin of 27.3%.
As a result of our strong third quarter financial performance and our expected operational improvements, we are raising our full-year earnings guidance for the new DuPont. Third quarter saw organic growth across all businesses with continued strong volume growth in healthcare and water, coupled with strength in electronics driven by AI technology demand in both interconnect solutions and semi. Today, we also announced capital allocation updates for the new DuPont, both in the form of a quarterly dividend and a new share repurchase authorization. We declared our initial quarterly dividend under new DuPont in the amount of $0.20 per share, in line with our targeted 35%-45% payout ratio.
Both of these actions underpin our commitment to a disciplined capital allocation model and are a testament to our financial strength and dedication to delivering value. As a premier pure-play technology solutions partner to the semiconductor value chain, CUNY is well-positioned to deliver growth and value creation for its shareholders. Our strategy is focused around driving above-market organic growth, building a robust business system, deploying a balanced capital allocation model, and consistently delivering results. We have successfully repositioned ourselves and have a streamlined portfolio of leading businesses, the majority of which are aligned to secular end markets, which will enable strong organic growth.
