Market and competitive read
NAPA’s commercial business continues to grow. System commercial sales rose approximately 4%, with company-owned commercial sales up approximately 5%. These figures alone don’t tell us whether NAPA gained or lost market share.
Company-owned stores are stronger than independent sell-in. Company-owned comps rose approximately 3.5%, including approximately 5% commercial growth. Independent purchases from NAPA were only slightly positive.
System sell-out provides the better view of end demand. Sales to end customers through company-owned and independent stores rose approximately 3%: commercial +4%, retail/DIY -3%. These differ from GPC’s reported sales into independents.
NAPA’s commercial growth trails AutoZone and O’Reilly. NAPA’s company-owned commercial comps rose approximately 5%, versus slightly over 10% professional comps at O’Reilly in Q3 and 8.6% domestic commercial sales growth at AutoZone in FQ4. O’Reilly’s growth was split roughly evenly between transactions and average ticket. The periods and measures differ, including program expansion in AutoZone’s figure, so these comparisons do not establish market-share transfers.
Demand remains soft. U.S. sales slowed from low-single-digit growth in July/August to slightly positive in September. October began near the overall Q3 trend. Management expects solid commercial demand, continued retail pressure and easier Q4 comparisons.
Costs, independents and inventory availability
Inflation is consuming operating progress. North America EBITDA fell approximately $6m to $194m; margin declined 40bp to 7.6%. Freight, fuel and rent rose approximately $15m combined. Management linked fuel/freight pressure to Iran and rent pressure to lease renewals; wage increases and healthcare inflation also weighed on results. Management estimates that without the freight, fuel and rent pressures, North America Automotive’s EBITDA margin would have increased approximately 20 basis points.
O’Reilly is absorbing higher service costs with stronger sales. Q3 selling, general and administrative expense per store rose 4.8%, yet the expense ratio improved 16 basis points. Management attributed most spending above its earlier forecast to service staffing and incentives supporting higher volumes; fuel, healthcare and insurance also added pressure. These are a mix of growth-related spending and inflation.
Independent-store performance is improving. Management said the bottom two quartiles improved sequentially from Q2 to Q3, while top-quartile owners grew at levels comparable to company-owned stores. Stronger owners are investing in inventory, people and service.
Technical knowledge complements availability. NAPA emphasizes experienced employees and local relationships. The competitive question is whether those strengths translate into orders when the required part and delivery service are available.
The supply-chain upgrade is progressing. The automated Eastern Pennsylvania DC opened on time and on budget; another U.S. facility is expected by year-end. Management sees broader assortment, better fill rates, automation savings and real-estate consolidation. Investment returns were not quantified on the call.

Upcoming catalyst
Separation could sharpen NAPA’s competitive focus. Completion remains targeted for Q1 2027. At Automotive’s December 8 Investor Day, watch for DC returns, independent-owner initiatives, operating targets and capital allocation.
