- Eos Energy shares climbed 11.7% to $7.61 in midday trading, beating the wider U.S. indexes.
- Company said it signed a binding supply framework for the German region one day after kicking off commercial production at its second battery line in Pennsylvania.
- Eos still faces an overhang from a planned rights offering as it looks for funds for its Frontier Power USA joint venture.
Eos Energy Enterprises shares jumped 11.7% around midday Wednesday. The zinc-battery maker announced its first international commercial framework for the Indensity storage system, bringing in a European demand signal. That comes a day after the company said its second Pennsylvania manufacturing line launched commercial production. The stock traded at $7.61, volume topping 19 million shares, after an early high of $7.71.
Eos is trying to show that there’s demand for its long-duration energy storage and that it can scale up production. This latest deal pushes that effort outside the U.S.
Eos and CAPAC Energy, which used to be Nala Energy GmbH, have struck a binding supply agreement for Germany, Austria and Switzerland that runs through 2031. The deal puts capacity at 750 megawatt-hours, and could grow to 2 gigawatt-hours. CAPAC is getting exclusive rights to distribute Eos products across the DACH region.
Nathan Kroeker, chief commercial officer at Eos, said the deal is “more than a supply agreement.” Benjamin Henecka, president and founder of CAPAC, called Germany “one of Europe’s most important storage markets.” Eos said any purchase orders under this framework will be added to its backlog. That means the contracted work hasn’t been booked as revenue yet. GlobeNewswire
Eos said Tuesday it kicked off commercial production at Battery Line 2 at its Thorn Hill facility in Marshall Township, Pennsylvania, after finishing site acceptance testing. The move helps push Eos closer to its target of 4 GWh annual manufacturing capacity by the end of 2026. Chief Operating Officer John Mahaz said the new line showed the system was “replicated and scaled with discipline.” GlobeNewswire
Eos got a boost from news of its foreign market entry and new production milestone, giving traders a clearer reason to buy than just the usual clean-energy story. The company is up against rivals in grid storage like Fluence Energy, which sells big battery systems, and Energy Vault, which offers storage for different durations. Fluence shares added 2.1%. Energy Vault climbed 1.1%. ESS Tech was up 4.8%.
The stock kept climbing even as the broader market looked shaky. Major U.S. indexes were up earlier Wednesday, ahead of the Fed’s policy decision. The Nasdaq Composite added 0.35% at 9:41 a.m. ET, Reuters reported.
The setup is messy. Eos said last week it would do a rights offering to raise funds for its capital payment to the Frontier Power USA joint venture. The offering lets current holders buy new securities, usually at a discount. Record date is July 1. Subscription price will be about 10% to 20% below a recent volume-weighted average trading price.
Execution is the risk now. Framework deals have to turn into real project orders. Projects still need permits and financing. New factories need to ramp up without cost overruns or quality problems. If anything stalls, investors may start worrying again about dilution, cash burn, and how quickly Eos can turn demand into sales.
Nasdaq traded normal hours Wednesday, opening at 9:30 a.m. and closing at 4 p.m. Eastern. The 2026 holiday schedule shows the exchange will shut on Friday, June 19 for Juneteenth.
