PART Act

The PART Act (HR5221), introduced on September 9, 2025, aims to prevent the theft of catalytic converters by requiring new motor vehicles to include catalytic converter identification. The bill was forwarded by a Subcommittee to a Full Committee by Voice Vote on February 10, 2026, indicating active legislative momentum. The bill mandates that the National Highway Traffic Safety Administration (NHTSA) revise existing regulations to include catalytic converters among specified parts for theft prevention and apply these requirements to new vehicles. This legislation does not include any direct funding authorizations or appropriations. Instead, it imposes a new regulatory requirement on automakers, which will translate into increased manufacturing costs for all new vehicles sold in the U.S. The mechanism is regulatory; automakers will bear the cost of implementing the identification requirements. There is no direct money trail from the government to specific companies or sectors. Structural winners are not explicitly defined by this bill, as it primarily imposes a cost. However, companies that can efficiently integrate the new identification requirements into their manufacturing processes may experience a smaller impact on their profit margins. Structural losers are automakers, including General Motors Company ($GM), Ford Motor Company ($F), Toyota Motor Corporation ($TM), Honda Motor Co., Ltd. ($HMC), and Stellantis N.V. ($STLA), as they will incur increased production costs. The bill's impact on these companies is a new regulatory burden rather than a direct financial gain or loss from government spending. Looking at recent market data, $GM is currently at $73.43, with a 30-day change of -3.64%. $F is at $11.61, with a 30-day change of -5.92%. $TM is at $204.42, with a 30-day change of -7.7%. $HMC is at $23.84, with a 30-day change of -13.21%. $STLA is at $7.48, with a 30-day change of +2.89%. These recent price movements reflect broader market dynamics and are not directly attributable to the PART Act's progress, as the bill's impact is a future regulatory cost rather than an immediate market catalyst. The next legislative step for HR5221 is consideration by the full committee(s) to which it was referred. The bill was referred to the Committees on Energy and Commerce, Transportation and Infrastructure, and the Judiciary. The sponsorship by Rep. Baird [R-IN-4] with 62 cosponsors indicates bipartisan support and a moderate level of legislative momentum. The recent subcommittee action on February 10, 2026, confirms the bill's active status.
