GWH (ESS Tech) a binary bet with positive EV (?)

AI Summary

The author presents ESS Tech (GWH) as a high-risk, positive-expected-value binary bet on iron flow battery scale-up, with an upcoming investor day and Arizona facility as catalysts.

GWH — LONG Author argues ESS Tech (GWH) is a positive expected-value binary bet because its iron flow battery lasts longer, cannot catch fire, and could become cheaper than lithium-ion at scale. Near-term catalysts include a proof-of-concept Arizona energy-provider facility and an upcoming investor day, plus a new CEO who may pursue big-tech deals. Main stated risks are insufficient cash, likely future dilution, strong failure odds, and vanadium-flow competition. The author holds a small stake and frames the upside as an average 5-bagger if the company overcomes those risks.

Realistically, there is an 70% chance they fail. However, I think if they are able to overcome that risk, it could be an easy 5-bagger (as an average). This poses a positive expected return.

The company ESS Tech, ticker GWH makes iron flow batteries. They seem to be the only company that has the resources & patents to make the type of battery with pretty much just saltwater and iron.

**The product now:** is more expensive and takes up more space than lithium ion batteries, however lasts significantly longer. It can't catch fire & doesn't have the same environmental concerns as lithium.

**The future product:** Has the potential to be cheaper than lithium ion per unit of energy storage, and has the potential to get cheaper, especially with scale.

**Challenges as a company now:** They don't have much cash left, and are desperately looking 'between couch cushions' for cash to scale. They historically have raised money by diluting shares, and they will likely dilute in the future.

**Growth opportunity now:** They are trying scaling up, despite facing strong risks of failure. As they shift from shipping container sized storage to warehouse facilities, maintaining contracts will be a make or break. They have a contract with an Arizona energy provider to build their biggest facility to date. This seems to be a proof of concept, and if it works it would lead to further contracts with bigger facilities.  
They also have a new CEO, who I believe will try to facilitate deals with big-tech.

**Competition:** They are the only company with the patents to make flow state batteries without expensive materials, however other companies can make similar flow batteries with vanadium. While more expensive, the vanadium can easily be resold, so the lifetime costs are similar, yet the vanadium batteries are more efficient (80% round trip VS 70% round trip)

**There is currently an upcoming investor day which will be a semi-major catalyst.**

Realistically, there is an 7**0% chance they fail**. However, I think if they are able to overcome that risk, it could be an easy 5-bagger (as an average). This poses a positive expected return.

*Disclaimer: I have a small stake of a few hundred shares. This is obviously a high risk - questionable reward binary bet.*
