Arbor Energy presents a compelling, albeit high-risk, equity opportunity with an expected upside of ~108.5% over a 2-year horizon.

Last updated: March 10, 2026

Bull (25%)+350%

Arbor's HALCYON system achieves early commercial success, securing major contracts beyond initial carbon removal agreements for data centers and industrial clients. Proprietary sCO2 and oxy-combustion technology proves highly efficient and cost-effective, allowing Arbor to capture significant market share in the rapidly growing zero-emission baseload power and carbon removal markets. This execution, coupled with strong investor demand for climate tech, drives a valuation to $1.5B+ by 2028.

Base (45%)+100%

Arbor successfully deploys its ATLAS pilot and progresses HALCYON, but faces slower-than-anticipated adoption due to high capital intensity and regulatory complexities. They secure additional funding rounds at a moderate step-up, maintaining a niche in the carbon-negative power segment and some baseload power, reaching a valuation of $680M by 2028.

Bear (30%)-80%

Delays in commercial deployment of HALCYON, coupled with intense competition from well-funded incumbents pivoting to similar clean power solutions, lead to significant market share loss. High capital requirements and regulatory barriers result in a down round or difficult fundraising environment, leading to an 80% reduction in valuation to $68M, severely impacting common stock value due to $55M in liquidation preferences.

Questions to Ask at the Interview

Strategic questions based on Arbor Energy's data — designed to show you've done your homework.

  • 1

    “Given the pivot to burning natural gas alongside biomass, how does Arbor plan to differentiate itself from traditional gas turbine manufacturers like GE and Siemens, beyond the efficiency gains of sCO2 and oxy-combustion, especially in terms of long-term carbon neutrality and cost competitiveness?”

  • 2

    “With HALCYON expected online by 2028 and plans for gigawatts of turbines by the end of the decade, what are the key milestones and potential bottlenecks in scaling manufacturing and deployment, particularly given the high capital intensity and supply chain considerations for 3D-printed components?”

  • 3

    “As a Series A company with $55M raised on a $340M valuation, what is the anticipated timeline for future funding rounds, and how does the company plan to manage potential dilution for employees holding common stock or options, especially considering the current $55M in liquidation preferences?”
