Exhibit 99.1

Dorman Products, Inc. Reports Third Quarter 2026 Results; Updates 2026 Guidance

Highlights (All comparisons are to the prior year period unless otherwise noted):

•Net sales of $561.7 million for the quarter, up 3.3%

•Diluted earnings per share (“EPS”) of $1.98, down 20%

•Adjusted diluted EPS* of $2.08, down 21%

•Generated $64.6 million of cash from operating activities; repurchased $15 million of shares

•Updates its full-year guidance for 2026

COLMAR, PA (October 26, 2026) – Dorman Products, Inc. (the “Company” or “Dorman”) (NASDAQ: DORM), a leading supplier in the motor vehicle aftermarket industry, today announced its financial results for the third quarter ended September 26, 2026.

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 $2.48 and $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 in the third quarter of 2025.

Gross profit was $221.6 million in the third quarter of 2026, or 39.4% of net sales, compared to $241.4 million, or 44.4% of net sales, in the same quarter last year. Adjusted gross profit* was $221.2 million, or 39.4% of net sales, in the third quarter of 2026, compared to $241.4 million, or 44.4% of net sales, in the same quarter last year.

Selling, general, and administrative (“SG&A”) expenses were $138.7 million, or 24.7% of net sales, in the third quarter of 2026, compared to $135.7 million, or 25.0% of net sales, in the same quarter last year. Adjusted SG&A expenses* were $132.4 million, or 23.6% of net sales, in the third quarter of 2026, compared to $129.9 million, or 23.9% of net sales, in the same quarter last year.

Diluted EPS was $1.98 in the third quarter of 2026, down 20% from diluted EPS of $2.48 in the same quarter last year. Adjusted diluted EPS* was $2.08 in the third quarter of 2026, down 21% compared to adjusted diluted EPS* of $2.62 in the same quarter last year.

Non-GAAP Financial Measures

(in thousands, except per-share amounts)

Our financial results include certain financial measures not derived in accordance with generally accepted accounting principles (GAAP). Non-GAAP financial measures should not be used as a substitute for GAAP measures, or considered in isolation, for the purpose of analyzing our operating performance, financial position or cash flows. Additionally, these non-GAAP measures may not be comparable to similarly titled measures reported by other companies. However, we have presented these non-GAAP financial measures because we believe this presentation, when reconciled to the corresponding GAAP measure, provides useful information to investors by offering additional ways of viewing our results, profitability trends, and underlying growth relative to prior and future periods and to our peers. Management uses these non-GAAP financial measures in making financial, operating, and planning decisions and in evaluating our performance. Non-GAAP financial measures may reflect adjustments for charges such as fair value adjustments, amortization, transaction costs, severance, accelerated depreciation, and other similar expenses related to acquisitions as well as other items that we believe are not related to our ongoing performance.

[1] – Pretax acquisition-related intangible asset amortization results from allocating the purchase price of an acquisition to the acquired tangible and intangible assets of the acquired business and recognizing the cost of the intangible asset over the period of benefit. Such costs were $5.1 million pretax (or $3.9 million after tax) and $15.4 million pretax (or $11.8 million after tax) during the three and nine months ended September 26, 2026, respectively. Such costs were $5.4 million pretax (or $4.1 million after tax) and $16.3 million pretax (or $12.3 million after tax) during the three and nine months ended September 27, 2025, respectively.

[2] – Pretax acquisition-related transaction and other costs include costs incurred to complete and integrate acquisitions and inventory fair value adjustments. During the three and nine months ended September 26, 2026, we incurred benefits included in cost of goods sold for acquisition-related reserve releases, net of inventory fair value adjustments of $0.4 million pretax (or $0.3 million after tax). During the three and nine months ended September 26, 2026, we incurred charges included in selling, general, and administrative expenses to complete and integrate acquisitions of $0.4 million pretax (or $0.3 million after tax) and $0.8 million pretax (or $0.6 million after tax), respectively.

Pretax acquisition-related transaction and other costs include costs incurred to complete and integrate acquisitions included in selling, general, and administrative expenses totaled $0.3 million pretax (or $0.2 million after tax) and $1.1 million pretax (or $0.8 million after tax), during the three and nine months ended September 27, 2025, respectively.

[3] – Pretax facility consolidation expenses represent costs incurred in connection with our planned facility consolidations and relocations. During the three and nine months ended September 26, 2026, such costs were $0.8 million pretax (or $0.6 million after tax).

[4] – Pretax bargain purchase gain resulted from the excess fair value of assets acquired in a business combination over the purchase price and was $1.5 million pretax (or $1.5 million after tax) during the three and nine months ended September 26, 2026, and was included in other income, net.

[5] – Pretax write-off of capitalized debt issuance costs totaled $0.8 million (or $0.6 million after tax) during the nine months ended September 26, 2026. These write-offs are associated with retirement of our term loan debt and the modification of our revolving credit facility.
