M&A activity snapshot
The biggest moves in auto parts distribution are portfolio decisions by public companies. Advance Auto Parts agreed in August 2024 to sell Worldpac, its automotive parts wholesale distribution business, to funds managed by Carlyle for $1.5 billion in cash. LKQ's board began a strategic review in January 2026 that includes a potential sale of the company. Genuine Parts announced in February 2026 that it will separate into two public companies, with completion targeted for the first quarter of 2027.
Deal volume across the wider aftermarket fell in 2025. Capstone Partners counted 194 automotive aftermarket transactions through early October 2025, 15.7% below the same period of 2024. That count includes parts manufacturers, service, and collision as well as distribution. Under NAICS, this vertical is code 423120, motor vehicle supplies and new parts merchant wholesalers.
Restructurings also create deal flow. American Tire Distributors completed its sale to new owners, Asphalt Buyer II LLC, after its bankruptcy.
Who is buying
Private equity. PE buyers made up 50.6% of aftermarket deal volume in 2025 through early October, the first PE majority since 2022, while strategic buyer activity fell 21.3%. Carlyle's Worldpac purchase is the clearest recent example of a sponsor buying a parts distributor at scale.
Strategic distributors and retailers. O'Reilly calls the aftermarket still highly fragmented and expects national chains' efficiency to drive continued consolidation. Parts Authority acquired Miami-based NPW Companies, adding 46 locations and bringing its network to nearly 325.
Trackers disagree on the buyer mix: Greenwich Capital Group found strategic buyers accounted for 91% of the North American aftermarket deals it tracked in Q4 2025. Different deal sets and periods explain the gap with Capstone's figure.
What buyers look for
Parts availability. Distributors win the professional installer by having the part on the shelf or on a truck quickly. AutoZone ended fiscal 2025 with 133 mega hub stores, each carrying about 80,000 to 110,000 SKUs, and more than 95% of O'Reilly stores receive multiple same-day deliveries. An independent distributor's fill rate and delivery times are the equivalent diligence items.
Professional (DIFM) customer mix. O'Reilly derived about 50% of 2025 sales from DIY customers and about 50% from professional service providers. Warehouse distributors that sell mainly to repair shops are buying the professional half, and buyers value first-call status with shops in a territory.
Fleet age and powertrain mix. AutoZone ties demand to vehicles seven years and older that are out of manufacturer warranty. Buyers also test exposure to categories that electric and hybrid vehicles may reduce or eliminate, as O'Reilly warns.
What makes a strong company
An auto parts or fleet distributor that commands a premium typically shows:
- A professional installer and fleet customer base with first-call status at many shops, not dependence on a few large accounts.
- Measured fill rates and same-day delivery coverage across its territory.
- Limited dependence on engine and powertrain categories that electric and hybrid vehicles may reduce or eliminate.
- Clean supplier and program-group relationships that transfer with ownership.
- For fleet distributors, documented service agreements with fleet operators rather than one-off counter sales.
Valuation and deal structure
Public benchmarks are well above typical private-deal levels. Greenwich Capital Group reports the automotive aftermarket public set traded at 13.8x EV/EBITDA at the end of 2025, and parts distributors and retailers averaged 14.1x TEV/EBITDA over five years.
For Worldpac, Advance disclosed about $2.1 billion of LTM revenue and about $100 million of EBITDA at the $1.5 billion sale price; neither company stated a multiple. No major provider publishes a lower-middle-market multiple for auto parts distribution. For a general starting point, see the Axia valuation tool.
Fleet and heavy-duty parts distribution has its own buyer set, but public data on that segment's deal multiples and market size is thin. The Auto Care Association's $599.7 billion 2026 forecast covers the U.S. total aftermarket without a heavy-duty breakout in the release.
Outlook
Demand looks steady. The total U.S. aftermarket is forecast to grow 5.4% in 2026 to $599.7 billion and reach $676.5 billion in 2029, and the light-duty segment is forecast to exceed $500 billion by 2029. Over the next 12-24 months, the outcome of LKQ's strategic review and the Genuine Parts separation will set the tone for consolidation. Independents with strong professional customer bases should see continued interest from both chains and sponsors.
