$EOSE manufacturer of grid scale zinc bromide batteries

When I look across some of the new battery technology makers such as ELVA, EOSE, AMPX, and ENVX there are a few story stocks there, and I consider ELVA to be the only one that is not a story stock.

I like to look at the financials of a business first before even knowing what the company does to see if this is a company I would invest on financials alone. That rules out a lot of companies including EOSE, AMPX, and ENVX who are all losing huge on profitability metrics.

Electrovaya has stood out for a few reasons from the crowd. The big one being they are GAAP profitable on the last two quarters, meaning they are becoming self sustaining and unlikely to require big capital raises or dilution. Another big factor is the valuation where ELVA is 250M market cap, and the other battery makers are all 1B+ valuations with lower quarterly revenue.

I first look at ELVA two quarters ago when their revenue jumped from 11.2M to 15M which is a huge percentage jump up. They also had EBITDA go from 0 to 1.8M, and net income go from -0.4M to 0.8M.

However, I did not invest then because many times these manufacturing based companies see pull-through, or have a large order land ahead of time. It may mean they are taking revenue from a future quarter potentially. It’s when they reported again going from 15M to 17.1M, EBITDA from 1.8 to 2.4M, and net income from 0.8 to 0.9M, that got me really interested.

Additionally, their latest earnings call showed up better in the narrative aspect to me than the prior earnings report. The narrative aspect is a completely subjective take, and I may take a note that management seems more enthusiastic. To a lot of people that can sound like a naive approach, in that I would be investing just based on how something “seemed” or “sounded”.

I’m not looking to make predictions with my investment approach. Using that numbers first approach, a company like Electrovaya has already proven cost discipline, profitability and growth. I remember Saul once saying we don’t want to do “guess work” and that is something that has stuck with me. Ideally I’ll let the company’s results dictate my next moves rather than trying to predict a technological trend. I’ve been wrong on dozens of companies I’ve posted about on the board, but the consistency in the approach ends up getting strong returns.

I will add that my approach used to be a bit different some 2+ years ago, where if a company has a strong enough narrative I was willing to overlook some unimpressive financials, simply because I thought I could trust in management more. I mentioned above in this thread Saul was quite critical of Amprius and that turned out to be correct as Amprius hit project delay after project delay. They had go back for more capital raises and the stock got crushed.

It’s a hard thing to do as an investor to admit we may have some mistake in our strategy, or at least some way to improve our strategy. If we’ve been investing for awhile, it means we have been compounding a strategy mistake for years, potentially holding us back from better results. For my own mistakes, I would value the narrative or futurism aspect of the business too much, and I would sometimes make extensive industry predictions.

As for timing those other companies of EOSE, AMPX, and ENVX, I will let the numbers dictate if we should make an investment. If they are able to reach profitability with strong growth numbers, and the story checks out through the conference call, then the timing may be right.

ELVA is not a grid scale battery company. It’s a company that makes batteries primarily for the forklift (and similar machinery) market.

There are tons of battery companies with promising tech. Why hasn’t anyone here mentioned QuantumScape, Solid Power, Factorial, Sila, Basquevolt, NuScale, Soteria, Zeta Energy, EnPower, Prieto Battery, etc.? (OK, maybe not all of those are public). But Samsung, LG, and even Toyota are all also investing in developing new battery technologies. Again, there’s so many I don’t know how to predict the winners.

Fair enough.

Well, we all remember Aspen Aerogels, who management got very excited before GM decided to move away from its Ultium battery tech, as its stock went from $30+ to under $8 recently.

But, I could certainly be wrong on ELVA.

@Smorgasbord1 You’re right. I should have just left it battery companies. I don’t know why I put them in the same market as EOSE. I just didn’t look at my own notes.

ELVA is getting in the energy storage market for data centers and warehouses, which to my understanding is a similar business EOSE is in. Seems like ELVA simply calls it the “storage products”. It’s probably where you got the idea from the two companies may overlap some.

Some quotes from the last earnings,

Our strategy includes a more aggressive pursuit of this sector, bolstered by our upcoming U.S.-based manufacturing capabilities. We are also working towards launching some specialized energy storage products later this calendar year that have been designed to leverage our technological strengths and specifically target a growing demand for domestically produced high-performance and, importantly, safe energy storage products. Investments in data centers, AI infrastructure, and overall greater need for improved energy infrastructure are driving this demand, and we believe we can provide our solutions while maintaining the strong margins, which we have demonstrated in other verticals.

The exception to that is on the energy storage side of things, where some of those same customers are the ones who have expressed interest in our energy storage products. So we will sell those same end customers we’re selling batteries for their material handling vehicles.

We may sell those same customers energy storage solutions.

Yes. We’ll be making a separate launch of that product fairly soon. So that’s why we haven’t put it as a separate item in our press release. But it’s a product line that our engineering team has been working on for some time. We want to make sure the specifications everything is perfect before we launch it.

That will come with our launch, which will be fairly soon. Again, we just want to make sure it’s all buttoned up before it gets launched. On the sites they’re considering, yes, it’s not these very large utility-scale type storage sites that we’re targeting. It would be specifically, for instance, warehouses where these warehouses typically have diesel gen sets outside. A lot of them have solar on their roofs.

So we will make deployments (energy storage) in calendar year 2026, and we will make shipments next year. So it’s a sector which is obviously very, very large, growing very quickly. We want to maintain our value there. We’re providing a battery solution, which is much safer longer longer lasting than what you can find from competitors.

Interesting that ELVA wants to get into that business. Maybe in a similar manner as Tesla went from battery driven cars to energy storage. Note that this for ELVA would probably be on the “short-term” (0-3 hours) storage market, which is the one that Tesla is in. EOSE is, for now anyway, concentrating on the medium term (Intraday) market (3-12 hours). Again, watch the video from The Limiting Factor I linked above for details on these markets and their differing battery requirements.

It does seem feasible that ELVA could have success in the short-term commercial backup market, but packaging, software, and pricing will have to be right. Electrovaya seems to tout safety as their primary advantage, which is important for customers looking to switch their material handling equipment batteries from tried and proven lead-acid to Li-Ion, but it’s unknown to me whether that’s a major concern with the short-term backup battery products currently available.

FWIW, Iren utilizes battery backup for their data centers, but I wasn’t able to find out any details on that aspect. They also have backup generators, almost certainly for cases where the power may be out for longer than the battery capacity can supply. Battery backup can supply instant power, whereas generators take time to start and warm-up, so everything has to be reboot if you’re only using generators.

In two recent interviews, Joe Mastrangelo, the CEO of EOS Energy, has mentioned 2 hour durations, so it seems that EOS batteries can handle that, although I believe the Limiting Factor video linked by Smorgasbord1 mentions that generally speaking Lithium batteries are optimized for shorter durations. However, the developer of a proposed 1GW data center in Green County, PA, has specified ~ 1.8 gwh of EOS batteries to provide 2 hour uninterruptible power. The batteries will interact with the grid and with the data center’s daily loads to keep the ~1 GW H-class gas turbines running at maximum efficiency rather than ramping the turbines themselves. 1.8gwh of EOSE batteries will produce perhaps as much as $500M in revenue. Keep in mind that in 2024 EOSE only had ~$16M in revenue and has projected 2025 revenue ~$170M. Analysts are guestimating 2026 revenue of ~$500M. Wrl’s concern (and mine too) is whether they will be able to scale efficiently, as ELVA has been able to. The fact that private equity firm Cerebrus Capital is a 33% owner of EOSE argues in favor of there being cost discipline.

As a final note, I asked Perplexity.Ai what the TAM of BESS and got this answer: The estimated total addressable market (TAM) for Battery Energy Storage Systems (BESS) over the next 25 years is projected to be in the range of 40 to 140 terawatt-hours (TWh) cumulative deployed capacity by 2050, depending on decarbonization speed, electrification, and grid flexibility needs.

Keep in mind that a terrawatt hour is a trillion watts. EOSE’s project AMAZE (American Made Zinc Energy) is to achieve 8gwh by 2027 (that’s 8 billion watts). My point is, the TAM in BESS is enormous, and there will likely be plenty of room for lithium and other battery chemistries to do very well tapping into it.

Took me a little bit to find a confirming link, since you didn’t provide one and spelled Greene County wrong:

EOS Energy is mentioned only once:

Eos Energy Enterprises is pioneering long-duration battery storage to support grid resilience and sustainable data center power strategies.

AFAICT, this is a proposed data center and its still early in those proposal stages. It appears to be tied to a data center in the same county:
https://www.businesswire.com/news/home/20250826531773/en/Essential-Utilities-to-Invest-%2426-Million-in-Major-Data-Center-in-Western-Pennsylvania

The data center will be powered by 944 MW of behind-the-meter, natural gas combined cycle combustion turbines (CCGTs), supplemented by battery storage, and backed up from an existing interconnection with the electric grid.

They’re targeting Q2 2028 for the gas turbines, operational 2029. More details on the approvals and such still needed are here: https://www.utilitydive.com/news/iep-plans-944-mw-behind-the-meter-gas-plant-in-pennsylvania-to-power-data-c/758830/

We’ll have to see where this one goes. I don’t see it as a reason to invest in EOSE now.

EOSE itself provides TAM numbers in the slide I’ve referred to multiple times in the video linked above. Here’s the EOS deck directly:

Two of the slides:

and

Here’s that slide:

So, EOS itself sees 115GWh as the TAM for their main/optimized application. Maybe they get a piece of the 34GWh.

And again, let me emphasize that the 3 markets EOS outlines have different requirements. It wouldn’t be unlikely that installations have combinations of 2 or all 3 of these types of batteries.

Potential investors should look at EOS’s latest earnings deck:

Slide 9 outlines their lead generation and opportunity pipeline.

Gross Margin -216% (that’s negative, as they are not profitable)
Slide 11 has financing information:

This is very much an unproven, non-profitable story stock.

My apologies for mindlessly accepting the Perplexity.AI answer to my query. Clearly a case of garbage in, garbage out.

In any event, thanks for taking the time to point out the flaws in my arguments. I’m hoping to avoid making a poor investment decision. Your input, as well as the input of others, is most appreciated.

NextEra SVP Petter Skantze says battery storage is now “the cheapest form of new capacity” in the US w/ “order of magnitude” faster deployment than gas w/ more modularity & flexible siting to enable higher system utilization & large load integration.
