EOSE
A rare good day for a battery maker
Eos Energy came out Wednesday and basically said: hey, Q2 was our best quarter ever. The company expects revenue of $68 million to $69 million, which would be the highest in its history, and shares responded by jumping nearly 10% in premarket trading Thursday. Not exactly subtle.
The part investors actually care about
This wasn't just a vanity metric parade. Eos said shipments more than tripled from a year earlier, first-half 2026 revenue already beat its total revenue for all of 2025, and backlog climbed to about $807 million as of June 30, up roughly 25% from the prior quarter. Translation: customers are still ordering, the pipeline is getting fatter, and the business has a little more visibility than your average solar-and-batteries roller coaster.
- New orders were higher than quarterly shipments, which is the kind of math investors love to hear
- Customer collections of about $78 million even topped quarterly revenue, a nice sign for cash conversion
- Total cash, including restricted cash, is expected to land around $364 million
The catch? Margins are still in the penalty box
Before we start throwing confetti, Eos also said gross margin loss likely came in between 69% and 73%. Why so ugly? The company started commercial production on Battery Line 2 during the quarter, and ramping a new manufacturing line is expensive. Think of it like opening a second restaurant: the line is longer, but you still have to buy the ovens, hire the staff, and survive the chaos before the fries start paying the rent.
Why this matters
Eos is trying to prove that higher production and real commercial demand can outgrow the startup pain. Management is betting the new line will improve unit economics over time, and if the backlog keeps growing, investors may be willing to look past the near-term margin bruise. The full earnings release lands on August 5th, and that one should tell us whether this is a real turnaround or just another promising battery story with a lot of current and not enough charge.
Big picture: Eos is showing progress where it counts — revenue, backlog, and production scale — but it still has to survive the ugly middle phase where growth looks great and margins look like a crime scene.
