Standing thesis

The standing, falsifiable read: what has to stay true, and what would break it.

Turnaround

Broken: Primary pillar broken — Move towards positive earnings and free cash flow: EPS -0.02 vs 0.02 target.

The bull case

Arq aims to grow revenue to about $122.5 million in 2026. The company has a new CFO with strong experience. Analysts expect revenue growth near 9% next year. The stock trades cheaply versus peers.

The bear case

Arq is still loss-making and has volatile management. Recent key officer departures hurt stability. Revenue growth is uncertain and may miss targets. The sector faces headwinds.

What's priced in

The market expects about 9% revenue growth and values the stock cheaply versus peers. Our fair value near $6.04 aligns with consensus, but risks remain from profitability and management changes.
