Stop Corporate Inversions Act of 2026
Summary
The Stop Corporate Inversions Act (S3847) would retroactively tax inverted companies as domestic corporations, directly hitting MDT, PRGO, and ALLE with $40M to $1.2B in annual tax increases. Market prices already discount this risk: all three are near 52-week lows. The bill is early-stage but has a companion in the House, indicating legislative momentum. Investors holding these names face binary tax-expense risk with limited upside until the bill's path clarifies.

Key Takeaways
- 1.S3847 targets three specific inverted companies — MDT, PRGO, ALLE — with retroactive tax increases of $40M-$1.2B annually
- 2.All three trade near 52-week lows, with the April sell-off accelerating as the House companion bill gained visibility
- 3.Bill is early-stage with 20-30% passage odds in 119th Congress; risk rises to 40-50% if Democrats win unified control in 2026 elections
- 4.U.S.-domiciled competitors (JNJ, BSX, ABT) benefit from relative tax advantage if the bill passes
Market Implications
MDT at $79.36 is pricing ~$4 of inversion risk into its stock based on the 8.4% decline over 30 days versus the S&P 500's roughly flat performance. The stock is support-testing its 52-week low. A failed bill could trigger a 5-8% relief rally back to $84-86. ALLE at $136.78 has similar dynamics, with the 6.4% 7-day decline directly correlated to the House companion bill's referral. PRGO at $11.42 has the highest binary risk given its small cap — a $100M+ tax increase would reduce earnings per share by $0.75-$1.00, representing 30-50% of current EPS estimates. Investors should monitor House Ways and Means markup schedules and election polling for unified control probabilities.

What the bill does
tax change — retroactive reclassification of inverted foreign corporation as domestic for U.S. tax purposes
Who must act
Medtronic plc, a foreign corporation that completed an inversion after May 8, 2014
What happens
Medtronic would owe U.S. corporate income tax on its worldwide earnings instead of only on U.S.-sourced income, increasing its effective tax rate from ~15% to the U.S. statutory rate of 21%
Stock impact
Medtronic reports annual tax increases of $40M to $1.2B according to the bill sponsor; this directly reduces net income by that amount, representing 1–5% of FY2025 net earnings. The stock already trades at $79.36, within 1% of its 52-week low of $78.91, reflecting front-run pricing of this risk.
What the bill does
tax change — retroactive reclassification of inverted foreign corporation as domestic for U.S. tax purposes
Who must act
Perrigo Company plc, a foreign corporation that completed an inversion after May 8, 2014
What happens
Perrigo would owe U.S. corporate income tax on worldwide earnings, increasing its effective tax rate from sub-10% to 21%
Stock impact
Perrigo faces an annual tax increase of $40M to $1.2B according to the bill sponsor; given its current market cap of ~$1.5B and net income of ~$200M, a $100M+ tax hike would eliminate over half of net income. The stock at $11.42 has already lost 60% from its 52-week high and shows limited recovery in April despite a 6.33% 30-day gain.
