What Does a High-Value Roundup Case Look Like?

If you developed non-Hodgkin lymphoma after years of using Roundup, you’ve probably wondered what a case like yours could be worth. It’s a fair question, and the best way to answer it isn’t with a guess — it’s with real cases that already went to trial.

Two landmark verdicts against Monsanto show exactly what drives a Roundup case toward the high end. By looking at what made these cases strong, you’ll get a clear picture of how case value actually works. Here’s what you’ll take away:

The factors that push a Roundup case toward higher value
How two real plaintiffs built winning cases
Why corporate knowledge played such a powerful role
What this means for you or your family

A quick, important note before we start: these are real outcomes, not promises. Every case is different, and no one can guarantee a result.

Two Real Cases That Shaped Roundup Litigation

Before we break down the factors, let’s meet the two men whose cases set the tone for thousands of others.

Dewayne “Lee” Johnson v. Monsanto

Lee Johnson was a California groundskeeper who sprayed Roundup as part of his job. He was diagnosed with terminal non-Hodgkin lymphoma, and in August 2018, his case became the first Roundup cancer lawsuit to reach a jury.

A San Francisco jury awarded him $289.2 million — $39.25 million in compensatory damages and $250 million in punitive damages. Through later reductions and appeals, his final award landed at $20.5 million. Monsanto chose not to take the case to the U.S. Supreme Court, ending the litigation.

Edwin Hardeman v. Monsanto

Edwin Hardeman used Roundup on his Sonoma County property from 1986 through 2012, treating poison oak, weeds, and overgrowth across 56 acres. He was diagnosed with B-cell non-Hodgkin lymphoma in 2015.

In spring 2019, a unanimous federal jury awarded him $80 million, including $75 million in punitive damages. The court later reduced the verdict to $25.2 million, and in 2022 the U.S. Supreme Court declined to disturb that judgment.

Two different men, two different exposures — but both cases share the same building blocks. Let’s break them down.

Factor 1: Long, Direct Exposure

Not all exposure carries the same weight. Brief, occasional contact is harder to tie to illness than years of hands-on use.

Both men had strong exposure histories:

Hardeman used Roundup for roughly 26 years, from 1986 to 2012, spraying it regularly across his large property.
Johnson sprayed Roundup directly as part of his daily groundskeeping work.

This kind of repeated, hands-on contact makes the link between Roundup and cancer far easier to establish. The longer and more direct the exposure, the stronger the foundation.

So what? Sustained, documented use is one of the first things that separates a strong case from a weak one.

Factor 2: A Serious Cancer Diagnosis

The severity of the illness drives much of a case’s value. Both men were diagnosed with non-Hodgkin lymphoma — a serious, life-threatening cancer.

Johnson’s diagnosis was terminal, which underscored the gravity of his harm to the jury. Hardeman’s B-cell NHL required medical treatment and forever changed his life.

A severe, well-documented cancer reflects greater suffering, more extensive treatment, and a deeper impact on a person’s future — all of which a claim accounts for.

So what? A serious, life-altering diagnosis is a major driver of case value.

Factor 3: Strong Medical Documentation

A diagnosis is only as persuasive as the evidence behind it. Both cases were backed by clear medical records and expert testimony.

Hardeman’s case featured testimony from his family physician, the doctor who diagnosed his NHL, and the specialist who treated him — plus a pathology expert who connected glyphosate to non-Hodgkin lymphoma to a reasonable degree of medical certainty.

That kind of consistent, layered documentation makes a claim much harder to dispute.

So what? Thorough medical records and credible experts turn a serious diagnosis into a provable one.

Factor 4: Lost Income and Quality of Life

A claim isn’t only about medical bills. It also reflects what a person loses in earnings and in daily life.

Johnson, a working groundskeeper, faced a terminal diagnosis that cut his life and livelihood short. Hardeman lost the health and independence he’d enjoyed on the property he tended for decades.

These losses — a shortened career, diminished earning power, and a changed way of life — form a significant part of any high-value claim.

So what? The toll on a person’s work and daily life is a real, measurable part of the case.

Factor 5: Pain, Suffering, and Human Impact

Some of the heaviest losses never appear on a bill. The law recognizes them anyway.

Both men endured the physical pain of cancer, the fear that comes with a serious diagnosis, and the emotional weight of fighting a disease they didn’t see coming. These non-economic harms — physical pain, emotional distress, and reduced quality of life — were central to both juries’ awards.

So what? The human cost of cancer is a core part of what a high-value case represents.

Factor 6: Evidence of Monsanto’s Corporate Knowledge

This factor turned strong cases into landmark verdicts. In both trials, plaintiffs presented internal Monsanto documents suggesting the company knew about the cancer risk and failed to warn users.

The numbers tell the story. In Johnson’s case, the jury awarded $250 million in punitive damages. In Hardeman’s, $75 million. Punitive damages aren’t about compensating the victim — they punish a company for serious misconduct. The Ninth Circuit even noted that “substantial evidence of Monsanto’s malice was presented to the jury.”

That evidence transformed these from ordinary injury cases into accountability cases.

So what? Proof that a manufacturer knew of the danger and stayed silent is one of the most powerful elements driving these verdicts.

Putting It All Together

Look at what these two cases shared, and the pattern becomes clear:

Long, direct, repeated exposure to Roundup
A serious — sometimes terminal — non-Hodgkin lymphoma diagnosis
Strong medical records and credible expert testimony
Lost income and a diminished quality of life
Real pain, suffering, and human impact
Powerful evidence of Monsanto’s corporate knowledge

No single factor wins a case. It’s the combination — strong exposure, severe harm, solid evidence, and corporate accountability — that builds a high-value claim.

What This Means for Potential Claimants

If your story sounds anything like Johnson’s or Hardeman’s, those shared factors may point to a meaningful claim of your own. The strongest cases tend to involve people who used Roundup regularly over time and were later diagnosed with non-Hodgkin lymphoma.

A few things to keep in mind:

Your exposure history matters. Where, how often, and how long you used Roundup all help build the picture.
Your medical records are central. A confirmed NHL diagnosis and treatment history anchor any claim.
Deadlines apply. California sets time limits on these claims, and waiting can cost you the right to file.
An early review helps. The sooner your case is evaluated, the more can be done to protect it.
