What this transaction means for investors

H Partners is a new activist investment firm that emphasizes buying underperforming equities that offer higher risk-reward ratios. In this sense, Advance Auto Parts is a perfect stock for them to buy as they are in the midst of a broad transformation, and hopefully a turnaround. Down 78% from its 2022 high, AAP watched peers O’Reilly Auto and **AutoZone **rocket past it as it struggled with mismanagement, supply chain issues, and poor pricing strategies.

However, once H Partners came on board alongside a couple of other activist investment firms, a new CEO was appointed, and a few board members with years of industry experience were added. Over the last year, AAP has started to show signs of life, with its stock up over 40% and its same-store sales positive again. The company sold 700 of its roughly 5,000 underperforming stores, exited California completely, and sold its low-margin wholesale distribution business to reduce its perilous debt load.

Following these moves, AAP’s adjusted operating income margin improved from -2.5% in the second half of 2023 to 2.5% in 2025. Management guided for this figure to rise to roughly 4% in 2026 and to one day hit 7% once it is firing on all cylinders. If the steadily streamlining company can get even close to these figures, it could be a steal at just 0.37 times sales. By comparison, O’Reilly Auto and AutoZone trade at 4.5 and 3.2 times sales, as the market assigns a premium valuation on their vastly more efficient operations. Powered by its new management – and bringing in Palantir and its software to improve its product assortment in each market – Advance Auto Parts is the rare turnaround stock I might actually believe in, and I see why H Partners is interested in adding shares.
