Dorman Products, Inc. Reports Third Quarter 2020 Results

Highlights:

COLMAR, PA (October 29, 2020) – Dorman Products, Inc. (the “Company” or “Dorman”) (NASDAQ:DORM), a leading supplier in the automotive aftermarket industry, today announced its financial results for the third quarter ended September 26, 2020.

3rd Quarter Financial Results

The Company reported third quarter 2020 net sales of $300.6 million, up 18.4% compared to net sales of $253.8 million in the third quarter of 2019. Sales performance in the quarter, a record high for the Company, was primarily organic and driven by improved customer demand.

Gross profit was $107.8 million in the third quarter compared to $86.9 million for the same quarter last year. Gross margin for the third quarter was 35.9% compared to 34.2% in the same quarter last year. Adjusted gross margin* was 36.6% in the third quarter compared to 34.3% in the same quarter last year. Adjusted gross margin expansion was primarily due to improved productivity at our Portland, TN distribution facility bringing costs back to historical levels, as well as lower provisions for excess and obsolete inventory as our efforts to improve our end-to-end supply chain processes began to show results.  

Selling, general and administrative (“SG&A”) expenses were $63.0 million, or 21.0% of net sales, in the third quarter of 2020 compared to $60.0 million, or 23.6% of net sales, in the same quarter last year. Adjusted SG&A expenses* were $61.9 million, or 20.6% of net sales, in the quarter compared to $59.2 million, or 23.3% of net sales, in the same quarter last year. Approximately 270 basis points of the decrease in SG&A as a percentage of net sales was due to improved leverage from the $47 million increase in net sales compared to the third quarter of 2019. Additionally, the Company drove operating cost savings in the quarter from productivity improvements at our Portland facility, as well as reduced travel expenses.

*Non-GAAP measures.  See Non-GAAP Financial Measures supplemental schedules for further discussion and reconciliation to the most directly comparable GAAP measure.

Income tax expense was $10.5 million in the third quarter of 2020, or 23.5% of income before income taxes, compared to $5.7 million, or 21.1% of income before income taxes, recorded in the same quarter last year.  The increase in the effective tax rate in the third quarter of 2020 is primarily due to the impact of foreign operations.

Net income for the third quarter of 2020 was $34.3 million, or $1.06 per diluted share, compared to $21.3 million, or $0.65 per diluted share, in the prior year quarter. Adjusted net income* in the third quarter was $36.8 million, or $1.14 per diluted share, also a record high for the Company, compared to $22.0 million, or $0.67 per diluted share, in the prior year quarter.

Kevin Olsen, Dorman Products’ President and Chief Executive Officer, stated, “First and foremost, I’d like to thank all of our Contributors whose dedication and commitment to our customers enabled us to deliver record- setting results for Dorman this quarter. We achieved record-high net sales and EPS this quarter, and our operating margin significantly improved, underscoring our ability to execute despite the challenging macroeconomic environment due to the COVID-19 pandemic. As the pandemic is ongoing, our number one priority remains focused on promoting the health and safety of our Contributors across our operations as we deliver for our customers in these unprecedented times. The highlight of the quarter was the robust end customer demand from ‘Do-It-Yourself’ customers as well as meaningful contributions from ‘Do-It-For-Me’ customers that continued throughout the entire quarter. We certainly faced challenges ramping up our supply chain to meet customer demand, but we demonstrated the agility of our business by meeting the significant demand increases while still maintaining the efficiency levels of our operations, and I want to thank our customers for their continued support. In line with our expectations, we achieved significant cost savings this quarter compared to a year ago, primarily due to improved productivity at our Portland facility as operating conditions have returned to more historical levels. Perhaps most importantly, our strategic imperative to bring innovation and solutions to customers and technicians in the aftermarket continues to bear fruit. Heavy Duty net sales were up 19% year-over-year, and our innovation teams launched several new-to-the-aftermarket products in the quarter, highlighted by steering shafts, electronic power steering racks, and pre-pressed axles.”

COVID-19: Business Update

The safety and health of our Contributors, business partners and customers continues to remain our top priority. We continue to monitor updates from local, state and federal authorities, and will adjust our operations as necessary. Dorman’s balance sheet remains healthy and strong enabling us to take the following actions in the third quarter:

As a result of these actions and the Company’s strong performance despite the COVID-19 pandemic, Dorman generated $146 million in cash from operating activities in the first nine months of 2020 and had approximately $170 million in cash and cash equivalents as of September 26, 2020.

During the third quarter, we estimate a negative impact of $0.03 to diluted EPS for out-of-pocket costs related to the COVID-19 pandemic.

Mr. Olsen continued, “Our liquidity remains strong, which, when combined with our asset-light model, allows us to operate in a variety of business environments. We remain confident in Dorman’s capacity to execute and look forward to continuing to deliver long-term value to our shareholders.”

2020 Guidance

Looking ahead, the COVID-19 situation remains uncertain and continues to evolve, and it is difficult to determine the full impact that the pandemic will have on overall demand and Dorman’s operations. Therefore, Dorman is not providing guidance for the remainder of fiscal 2020.

Share Repurchases

Dorman resumed its share repurchase program in the third quarter and repurchased 126.9 thousand shares of its common stock for $10.7 million at an average price paid per share of $84.55 during the quarter ended September 26, 2020.

In addition, the Company announced that its Board of Directors authorized an expansion and extension of its share repurchase program, which previously would have expired on December 31, 2020 and permitted share repurchases up to $400 million. The expanded program authorizes share repurchases up to $500 million through December 31, 2022. Following the expansion, the Company has $227.7 million left under the program for share repurchases.

Such costs were $0.1 million pretax (or $0.1 million after tax) during the nine months ended September 28, 2019 and were included in Cost of goods sold.

[2] – Pretax acquisition-related intangible asset amortization results from allocating the purchase price of acquisitions 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 $0.8 million pretax (or $0.6 million after tax) during the three months ended September 26, 2020  and $2.4 million pretax (or $1.8 million after tax) during the nine months ended September 26, 2020 and were included in Selling, general and administrative expenses.

[3] – Pretax acquisition-related transaction and other costs include costs incurred to complete and integrate acquisitions, adjustments to contingent consideration obligations, and facility consolidation expenses. During the three months ended and nine months ended September 26, 2020, we incurred charges for integration costs, severance, other facility consolidation expenses and inventory transfer costs of $0.1 million pretax (or $0.1 million after tax) and $0.7 million pretax (or $0.5 million after tax), respectively, which were included in Cost of goods sold. During the three months ended and nine months ended September 26, 2020, we incurred charges to complete and integrate acquisitions as well as accretion expenses related to contingent consideration obligations of $0.3 million pretax (or $0.2 million after tax) and $1.3 million pretax (or $1.0 million after tax), respectively, which were included in Selling, general and administrative expenses.

During the three months ended September 28, 2019, we incurred charges for integration costs, severance, and other facility consolidation expenses of $0.1 million pretax (or $0.1 million after tax). Additionally, we recorded inventory transfer costs of $0.1 million pretax ($0.1 million after tax) during the three months ended September 28, 2019 which were included in Cost of goods sold. During the nine months ended September 28, 2019, we incurred charges for integration costs, severance, and other facility consolidation expenses of $2.0 million pretax (and $1.5 million after tax) and accelerated depreciation of $0.8 million pretax (or $0.6 million after tax).

Additionally, we recorded inventory transfer costs of $0.2 million pretax ($0.2 million after tax) during the nine months ended September 28, 2019 which were included in Cost of goods sold.    

[4] – Pretax gain on equity method investment results from the acquisition of the remaining outstanding shares of a previously unconsolidated entity.  The estimated fair value of the net assets acquired was more than the carry value of our prior investment in the entity.

[5] – Noncash impairment related to equity method investment represents our share of an impairment recognized by an equity investment investee. The adjustment was $2.1 million (or $1.6 million after tax) during both the three months and nine months ended September 26, 2020.

Such items are estimated by applying our overall estimated tax rate to the pretax amount, or, by applying a specific tax rate if one is appropriate.  

[7] – Tax benefit represents a reversal of a deferred tax liability related to an equity method investment which was converted to a consolidated subsidiary upon acquisition of the controlling interest. The benefit was $0.8 million during the nine months ended September 26, 2020.
