Kevin Olsen, Dorman’s Chairman, President, and Chief Executive Officer, stated, “We delivered solid performance in the quarter. Net sales increased 3%, with top-line growth across each of our three business segments driven by new products and business wins. Diluted EPS was $1.98, and adjusted diluted EPS was $2.08, compared to $2.48and $2.62, respectively, in the prior-year period. The year-over-year earnings comparison reflects the timing of tariff-related pricing that benefitted the third quarter of 2025. We also generated $65 million of operating cash flow and repurchased $15 million of our common stock in the quarter, bringing year-to-date share repurchases to a company record of $112 million. “Given our performance through the first nine months of the year and additional pricing actions we expect to take in the fourth quarter, we are narrowing our full-year 2026 guidance. We now expect full-year net sales growth to be in the range of 2% to 3%, diluted EPS in the range of $7.95 to $8.15, and adjusted diluted EPS in the range of $8.50 to $8.70. “Supported by our strong balance sheet and liquidity position, and the strategic advantages of our innovation engine and diversified supplier network, we remain confident in our long-term growth strategy.” Third Quarter Financial Results The Company reported third quarter 2026 net sales of $561.7 million, up 3.3% from net sales of $543.7 million inthe third quarter of 2025.
