Bayer Lobbying Rebounds As Roundup Legal Fight Reaches Supreme Court

Bayer increased its federal lobbying spending in the first quarter of 2026 as the U.S. Supreme Court prepares to hear arguments Monday in a case involving Monsanto, which Bayer acquired in 2018.

New federal disclosures show Bayer reported just over $2 million in lobbying expenses from January through March, up from $1.75 million in the fourth quarter of 2025. The increase follows a drop in spending during the second half of last year after Bayer’s quarterly lobbying peaked at $2.95 million in early 2025.

While 2025 filings showed the company “monitoring” broad issues like pesticide regulations and biotech innovation, the new 2026 report reveals a laser-focus on specific legislation designed to provide the company with a legal shield against ongoing lawsuits.
