Eos Energy Enterprises (EOSE) traded around $8 ahead of the U.S. market holiday, as Frontier Power USA, which is backed by Cerberus and linked to Eos, closed an initial project deal under its 2 GWh capacity reservation with the battery firm.
Frontier’s plan is now past the financing stage and into project testing. The company’s 480 megawatt-hour portfolio of stored energy is about 24% of its 2 gigawatt-hour reservation. It covers three projects tied to ERCOT, Texas’s main grid, with one 100 MW/400 MWh project up for notices to proceed in mid-2026. GlobeNewswire
U.S. stock markets are closed for the long Memorial Day weekend, reopening Tuesday. Wall Street finished higher before the break. The Dow ended at a fresh record on Friday and the S&P 500 posted another week of gains. The Nasdaq Composite ended at 26,343.97, edging up 0.19%. Reuters Nasdaq Global Index Watch
Eos shares closed Friday at $8.06, according to the company’s price table using LSEG data. Trading volume for the day came in around 24.6 million shares. The stock finished Tuesday at $6.88, moved up to $7.11 on Wednesday, then popped to $8.17 on Thursday before giving back some gains. Eos Energy Enterprises, Inc.
Frontier Power USA is expected to pick up projects and use Eos systems along with technology performance insurance, or TPI, insurance that aims to give lenders some assurance that battery systems will deliver as promised. The project news gives investors a simpler way to track the Cerberus partnership announced earlier this month.
Aaron Maczonis, managing director at Cerberus Capital Management, said the Texas portfolio is an “important first step.” Cole Johnson, co-CEO of Bimergen Energy, said the company can rotate assets and still keep “an ongoing interest” in how they perform long term. GlobeNewswire
Eos is still trying to scale, not hitting mature margins yet. First-quarter revenue jumped 445% from last year to $57.0 million, and the company kept its 2026 revenue outlook at $300 million to $400 million. It still had a gross loss of $44.4 million and an adjusted EBITDA loss of $68.0 million. Adjusted EBITDA, which takes out interest, tax, depreciation, amortization and some company-specific items, is a way to look at operating numbers before some costs hit. Eos Energy Enterprises, Inc.
Eos CEO Joe Mastrangelo was blunt after earnings, saying the “work ahead is conversion.” The company closed March with a $24.3 billion commercial pipeline and a $644.6 million backlog. Pipeline doesn’t equal booked revenue.
Competition is still a factor. Eos says its zinc-bromide batteries compete with lithium-ion, lead-acid, sodium sulfur and vanadium redox for stationary storage. Market research firms mention Fluence Energy and ESS Inc. as North American rivals in the storage market. The Department of Energy’s Energy.gov Grand View Research
Nasdaq won’t trade Monday, making it a short week. Investors waiting for the next move will have to wait until Tuesday. Eos’s annual meeting is set for June 3, its next big listed event. The company has also said its second battery line should hit initial production by quarter’s end. NASDAQ Trader Eos Energy Enterprises, Inc.
Risk is clear here. The Frontier deal still needs a rights offering, shareholder nod for more shares, DOE approval, and final contracts. The warrants and rights offering tied to it could hit existing holders. Eos also must show that ramping up output cuts losses, not just boosts revenue. Eos Energy Enterprises, Inc.
