Treat and Reduce Obesity Act of 2025
Summary
The Treat and Reduce Obesity Act of 2025 would mandate Medicare Part D coverage of GLP-1 obesity drugs, unlocking a massive new payer market of ~27 million beneficiaries. $NVO and $LLY are the two direct beneficiaries. The bill is in early-stage committee referral with 22 bipartisan cosponsors; no companion bill has passed the House yet. Real market data shows $NVO gaining 15.56% over 30 days vs $LLY's +0.7%, suggesting the market may be overweighting Novo's near-term Medicare exposure given its larger U.S. obesity market share.

Key Takeaways
- 1.S.1973 would mandate Medicare Part D coverage of GLP-1 obesity drugs, unlocking 27M Medicare beneficiaries as new patients
- 2.$NVO (Wegovy) and $LLY (Zepbound) are the two direct beneficiaries with obesity-specific drug franchises
- 3.Bill is early-stage (referred to committee, no hearings yet); bipartisan support but uncertain path to law
- 4.Real market data shows $NVO +15.56% vs $LLY +0.7% over 30 days, suggesting market pricing in a Novo premium on Medicare exposure
- 5.No companion bill has passed either chamber; attaching to year-end must-pass legislation is the most likely path to enactment
Market Implications
The divergence in recent price action between $NVO (+15.56% in 30 days) and $LLY (+0.7%) presents a potential rotational opportunity if the market is underestimating LLY's exposure. Both companies have FDA-approved obesity drugs; the Medicare expansion is neutral in terms of net benefit per patient. The risk is that the bill stalls — early-stage legislation with 22 cosponsors has roughly a 10-20% historical passage rate. If investors seek a pure-play bet on Medicare expansion, $NVO at $42.47 is already pricing in some success. $LLY at $926.25 is 18% off its 52-week high of $1,133.95, offering more upside if the bill gains momentum. Both stocks are high-beta plays on a single legislative catalyst; sector investors should monitor Finance Committee hearing announcements closely.

$LLY's Zepbound (tirzepatide) for obesity is a direct beneficiary; Medicare Part D coverage removes a major access barrier and could drive a surge in prescriptions, adding billions in annual revenue. LLY's current U.S. obesity drug revenue is estimated ~$5B; Medicare could add 30-50% incremental revenue, depending on pricing and utilization management.

Promoting Efficiency, Accountability, and Performance in Federal Contracting
This executive order mandates that federal agencies default to using fixed-price contracts for procurement, shifting away from cost-reimbursement models. It requires written justification and senior-level approval for any non-fixed-price contract over certain dollar thresholds (e.g., $10M for most agencies, $100M for the Department of War), and directs agencies to review and renegotiate their 10 largest non-fixed-price contracts within 90 days. The order also tasks OMB with implementation guidance and the Federal Acquisition Regulatory Council with proposing regulatory amendments within 120 days.
Accelerating Medical Treatments for Serious Mental Illness
