Exhibit 99.1

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

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

•Net sales of $544.6 million for the quarter, up 0.7%

•Diluted earnings per share (“EPS”) of $2.93, up 53%, and adjusted diluted EPS* of $3.08, up 50%

•Generated $152.6 million of cash from operating activities; repurchased $47 million of shares

•Earnings and cash from operating activities benefited from IEEPA tariff cost recovery*

•Updates its full-year guidance for 2026

COLMAR, PA (August 3, 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 second quarter ended June 27, 2026.

Kevin Olsen, Dorman’s Chairman, President, and Chief Executive Officer, stated, “Our second quarter results included record earnings and strong cash flow generation, reflecting both solid operating performance and the recovery of IEEPA tariff costs recognized in prior periods. Year-over-year, net sales for the quarter increased 1% to $545 million, diluted EPS increased 53% to $2.93, and adjusted diluted EPS increased 50% to $3.08. In addition, we generated $153 million of operating cash flow in the quarter and returned capital to shareholders through $47 million of share repurchases. We believe our cash flow generation positions the company well to make strategic investments and drive long-term growth.

“Given our performance through the first half of the year and targeted pricing actions we are taking as a result of a more stable tariff environment, we are updating our full-year 2026 guidance. We now expect net sales growth of 3% to 5%, diluted EPS in the range of $7.93 to $8.23, and adjusted diluted EPS in the range of $8.50 to $8.80.

“Supported by our strengthened balance sheet, expanded liquidity from our recent debt refinancing, and the strategic advantages of our diversified supplier network and innovation engine, we remain confident in our ability to deliver differentiated solutions for our customers and strong value for our shareholders.”

Second Quarter Financial Results

The Company reported second quarter 2026 net sales of $544.6 million, up 0.7% compared to net sales of $541.0 million in the second quarter of 2025.

Gross profit was $251.2 million in the second quarter of 2026, or 46.1% of net sales, compared to $219.5 million, or 40.6% of net sales, in the same quarter last year.

Selling, general, and administrative (“SG&A”) expenses were $135.0 million, or 24.8% of net sales, in the second quarter of 2026, compared to $137.0 million, or 25.3% of net sales, in the same quarter last year. Adjusted SG&A expenses* were $129.6 million, or 23.8% of net sales, in the second quarter of 2026, compared to $131.3 million, or 24.3% of net sales, in the same quarter last year.

Diluted EPS was $2.93 in the second quarter of 2026, up 53% compared to diluted EPS of $1.91 in the same quarter last year. Adjusted diluted EPS* was $3.08 in the second quarter of 2026, up 50% compared to adjusted diluted EPS* of $2.06 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 $5.2 million pretax (or $3.9 million after tax) and $10.3 million pretax (or $7.9 million after tax) during the three and six months ended June 27, 2026, respectively. Such costs were $5.4 million pretax (or $4.1 million after tax) and $10.9 million pretax (or $8.2 million after tax) during the three and six months ended June 28, 2025, respectively.

[2] – Pretax acquisition-related transaction and other costs include costs incurred to complete and integrate acquisitions and facility consolidation expenses. During the three and six months ended June 27, 2026, we incurred charges included in selling, general, and administrative expenses to complete and integrate acquisitions of $0.2 million pretax (or $0.2 million after tax) and $0.5 million pretax (or $0.4 million after tax), respectively. Such costs were $0.3 million pretax (or $0.2 million after tax) and $0.8 million pretax (or $0.6 million after tax), during the three and six months ended June 28, 2025, respectively.

[3] – Pretax write-off of capitalized debt issuance costs totaled $0.8 million (or $0.6 million after tax) during the three and six months ended June 27, 2026. These write-offs are associated with retirement of our term loan debt and the modification of our revolving credit facility.

[4] – Pretax reduction in workforce costs represents costs incurred in connection with our planned workforce reduction, including insurance continuation costs. During the three and six months ended June 28, 2025, the expenses were $0.0 million pretax (or $0.0 million after tax) and $0.1 million pretax (or $0.1 million after tax), respectively.

[5] – Tax adjustments represent the aggregate tax effect of all non-GAAP adjustments reflected in the table above and totaled $(1.5) million and $(2.8) million during the three and six months ended June 27, 2026, respectively, and $(1.4) million and $(2.9) million during the three and six months ended June 28, 2025, respectively.
