• The company estimated a full-year impact of approximately $1.25 on adjusted diluted EPS due to additional tariffs.

They noted 'outstanding financial performance for the year' with 'record sales from new products' and 'meaningful margin expansion and earnings growth.'

Q&A:

• Question from Scott Stember (ROTH Capital): Trying to get a sense of how the light-duty business is doing, specifically on POS growth and volume, and how you guys are matching up with what the O'Reilly's and the AutoZone's are saying.
  Response: Light-duty macros remain very strong with mid-single-digit POS growth in Q4, similar to Q3, driven by increasing vehicle age and miles driven. A large customer's order pattern change in Q4 impacted sales, but underlying demand remains constructive for 2026.

• Question from Bret Jordan (Jefferies LLC): Could you parse out what of the inventory growth is in tariff price, units versus cost?
  Response: The largest proportion of inventory growth is from higher tariff costs, with some lift from increased volume and purchasing ahead of tariffs.

• Question from Jeffrey Lick (Stephens Inc.): What gives you confidence in the 7-9% sales guidance given exit rates, and how does the tariff benefit flow through?
  Response: Confidence is based on: a large customer's order normalization post-Q4, record new product sales carryover, and a full-year benefit from 2025 pricing actions that began mid-year. Tariff cost impacts are expected in H1 2026, with margins pressured by higher cost inventory before improving in H2.

• Question from Tristan Thomas-Martin (BMO Capital Markets): How should we think about your content TAM on an EV versus an ICE vehicle?
  Response: Dorman is drivetrain agnostic. Complex Electronics is the fastest-growing part of the portfolio and represents the highest proportion of the new product pipeline, viewed as a competitive moat with higher ASPs.

• Question from David Lantz (Wells Fargo): Within the 7-9% top line sales guidance, can you parse out subsegment performance, and how are you thinking about M&A vs. share repurchases?
  Response: Growth is expected across all three segments driven by new product development, pricing, and market share gains. Capital deployment prioritizes debt management, organic investment, and M&A; with dry powder available, they expect higher M&A activity in 2026, but will return capital via buybacks if opportunities don't arise.

• Question from Gary Prestopino (Barrington Research): Can you quantify the growth contribution from new products, especially in Complex Electronics?
  Response: Management declined to break out specifics for competitive reasons but highlighted record new product sales dollars in 2025, a growing funnel of repair opportunities, and confidence in delivering outsized growth (7-8%) vs. the market.

• Question from Justin Ages (CJS Securities): What's driving the new business wins in heavy duty, and what are the productivity and automation initiatives?
  Response: Wins are a combination of share gains and new product development. Productivity initiatives include global sourcing optimization, automation in distribution centers (reducing labor costs), and process improvements (e.g., in new product development).

• Question from Bret Jordan (Jefferies LLC): Given the lack of aftermarket competitors in Complex Electronics, is the gross margin substantially higher?
  Response: Yes, Complex Electronics typically competes against OE and carries a high level of gross margin percentage, with management aiming for commensurate returns on high investment.
