Investment Highlights Why It Matters Which of these 2 stories sounds closer for this stock?

1. Generates cash flow

The stock generated 4% or more of the share price (called cash flow yield), and shows moderate 10-15% or more growth.

2. Riding a trend

Think Tesla during the pandemic of 2020 when EVs were riding a cultural high, or Nvidia in the current AI boom, or even Figma. These companies don’t have enough yield, or, enough growth, or both - however - they are riding a trend. They have momentum. These can be more volatile - they don’t have the floor of strong cash flow

Here are five key points explaining the significant movement in SAB Biotherapeutics (SABS) stock, from the approximate period of August 31, 2025, to December 18, 2025:

1. Positive Topline Phase 1 Clinical Results for SAB-142. SAB Biotherapeutics announced positive topline Phase 1 clinical results for SAB-142, a potential disease-modifying therapy for Type 1 Diabetes (T1D), on January 28, 2025. The trial, conducted among healthy volunteers, met its primary objectives related to safety, tolerability, pharmacokinetics, immunogenicity, and pharmacodynamics, with no reports of serum sickness or anti-drug antibodies at the target dose. This early success for their lead candidate provided a significant boost to investor confidence.

2. Advancement to Phase 2b Clinical Trials for SAB-142. Following the promising Phase 1 data, SAB Biotherapeutics outlined plans to advance SAB-142 into Phase 2b clinical trials in 2025, focusing on adult and pediatric patients with new-onset T1D. By November 2025, the company had initiated its registrational Phase 2b SAFEGUARD trial, activating multiple sites across the U.S., Australia, and New Zealand, and was on track to dose the first patient by year-end 2025. The progression to a pivotal trial stage indicated strong momentum in the development of SAB-142.
