PART Act
Summary
The PART Act (HR5221) imposes a minor compliance cost of $3–$8/vehicle on new car OEMs to mark catalytic converters with identifying numbers. The bill is early-stage — forwarded to full committee by voice vote in February 2026. For US-traded automakers GM, F, and STLA, the annual cost burden ($5M–$18M each) is immaterial relative to revenue and does not change competitive dynamics. No impact on stock fundamentals.

Key Takeaways
- 1.PART Act imposes $3-$8/vehicle compliance cost on new car OEMs — immaterial to GM, F, STLA financials
- 2.Bill is early-stage (subcommittee → full committee only); no Senate companion; low probability of enactment in 2026
- 3.No direct revenue impact on any public company — this is a pure cost imposition with no offsetting winners
- 4.GM, F, and STLA recent price moves are driven by macro/tariff/earnings factors, not this bill
Market Implications
For retail investors holding GM, F, or STLA, the PART Act is not a factor worth monitoring. At $3–$8/vehicle, the annual cost burden is $6M–$18M for GM, $5M–$15M for Ford, and $4M–$12M for Stellantis. Compare this to GM's $76.62 share price and $100B+ market cap, or F's $12.24 price — the impact rounds to zero. If the bill progresses to a vote (currently unlikely in 2026), expect zero price reaction. Focus on the actual drivers: tariff policy on Mexican/Canadian imports, EV tax credit extension, and the companies' Q1 2026 earnings reports due in May.
Full Analysis
-
WHAT HAPPENED: Representative James Baird (R-IN-4) introduced HR5221, the Preventing Auto Recycling Theft Act (PART Act), on September 9, 2025. The bill requires NHTSA to revise the motor vehicle theft prevention standard to include catalytic converters, mandating that new vehicles have identifying numbers etched or inscribed on these parts. The bill was forwarded from the Subcommittee to the Full Committee by voice vote on February 10, 2026 — a positive procedural step but early in the legislative process. The bill has 62 cosponsors, bipartisan support, and has been referred to three committees (Energy & Commerce, Transportation & Infrastructure, Judiciary).
-
THE MONEY TRAIL: There is no funding in this bill. It is a regulatory mandate — it directs NHTSA to update an existing regulation (49 CFR 541.5) at zero direct federal cost. The cost falls entirely on OEMs as a compliance expense. Estimated at $3–$8/vehicle, the total annual industry burden is approximately $45M–$120M across ~15M new vehicles sold annually in the U.S. This is not an authorization or appropriation; it is a cost imposition on private industry.
-
STRUCTURAL WINNERS AND LOSERS: This bill has no structural winners. Aftermarket parts manufacturers (catalytic converter replacement units) may see a minor increase in demand from the mandated identification, but the bill does not specify that aftermarket converters require identification — only new vehicles. Scrap yards and recycling centers face expanded record-keeping requirements per other sections of the bill, but this adds operational cost. Law enforcement gains a tracking tool but that is not a market factor. The three US-traded automakers are the only publicly-traded entities with direct exposure, and that exposure is a minor cost headwind.

MARKET DATA ANALYSIS: As of April 29, 2026, GM closed at $76.62 (7-day -2.42%, 30-day +5.31%), Ford at $12.24 (7-day -1.92%, 30-day +9.19%), and Stellantis at $7.70 (7-day -7.12%, 30-day +14.07%). The 7-day declines for all three align with broader market weakness, not the PART Act — the bill's last action was February 10, 2026, over two months before these price moves. The 30-day positive returns (particularly STLA's +14%) reflect other factors (Q1 earnings, tariff policy changes, EV strategy updates). The PART Act's impact is not detectable in any of these price movements.
-
TIMELINE: The bill has cleared one subcommittee but still needs: full committee markups in all three referred committees, House floor vote, Senate introduction and passage (no companion bill yet), and Presidential signature. The 119th Congress runs through January 2027. With split-chamber control (Republican House, Democratic Senate), passage before the 2026 midterm elections is possible but not probable given the bill's low priority relative to budget, appropriations, and tax extenders. If passed, the 180-day NHTSA rulemaking clock begins upon enactment.

What the bill does
Mandate to affix or inscribe identifying numbers on catalytic converters for all new vehicles covered by part 565 of title 49, CFR, within 180 days of NHTSA rulemaking revision.
Who must act
New vehicle OEMs manufacturing vehicles for U.S. sale — specifically GM, Ford, and Stellantis as the three US-traded automakers named in the bill's market impact scope.
What happens
Per-unit compliance cost of $3–$8 per vehicle. No offsetting revenue. The cost is a minor incremental COGS increase on all new light-duty vehicles sold in the U.S. after the effective date.
Stock impact
GM's U.S. vehicle sales volume of ~2.3M units annually implies an incremental cost burden of roughly $7M–$18M per year. This is trivial relative to GM's ~$180B annual revenue. No competitive disadvantage vs. other OEMs as the mandate is across all covered vehicles. No effect on GM's core truck/SUV margins or EV transition costs.
What the bill does
Same NHTSA-mandated identification requirement applies to all Stellantis vehicles sold in the U.S.
Who must act
Stellantis N.V. — specifically its North American operations (Ram, Jeep, Dodge, Chrysler brands).
What happens
Stellantis's ~1.5M U.S. annual sales imply a $4.5M–$12M annual cost increase. Immaterial relative to Stellantis's ~$190B revenue. Bill does not differentiate by OEM size or margin structure.
Stock impact
STLA currently trades at $7.70. The compliance cost is noise vs. the company's structural challenges (declining U.S. market share, EV transition capex, inventory glut). No change to competitive position — Toyota, Honda (not US-listed) face same per-unit cost.

It also orders the Labor Department to review past labor condition applications for potential enforcement actions against sponsoring employers, effectively tightening scrutiny on H-1B usage, especially by outsourcing firms.
RESTORING AMERICAN SALTWATER ANGLING AND RECREATION
This executive order directs federal agencies (primarily NOAA and the Department of Commerce) to shift fisheries management toward prioritizing recreational fishing over commercial interests by modernizing data collection, replacing outdated mail-in surveys with real-time mobile reporting, and allowing state-collected data to substitute for federal data when error rates are lower. It also mandates reviewing and potentially revising National Standards under the Magnuson-Stevens Act, rescinding regulations that restrict marine access, and launching pilot programs for iconic fisheries like Atlantic striped bass, with the goal of boosting the $1.2 trillion outdoor recreation sector.
Restoring Reciprocity in Government Procurement
This Presidential Memorandum directs the Office of Management and Budget, the U.S. Trade Representative, and other federal agencies to identify and remove Canadian-origin items from federal civil procurement where possible, citing Canada's 'Buy Canadian' policies as discriminatory. It also requires agencies to be notified of domestic alternatives and mandates ongoing monitoring of Canada's procurement practices, with provisions for restoring access if Canada changes its policies.
