The Eos Energy Enterprises story
What drives Eos Energy Enterprises, what its price assumes and what could change the story, written from its own filings.
Orders outpace execution. Eos reported a record $807 million backlog at June 2026, up 25% sequentially, but converting orders into profitable deliveries remains unfinished.
Margins remain negative. In the quarter to June 2026, revenue reached $68.8 million while gross margin remained negative 71%, despite improving 7 percentage points sequentially.
Consolidation narrows guidance. Eos narrowed its full-year 2026 revenue guidance to $300 million to $350 million from $300 million to $400 million as it evaluated manufacturing consolidation timing.

What the release says
Highlights
Eos Energy booked a $100 million purchase order for Phase I of the Blanquilla project under Frontier Power USA’s 2 GWh Capacity Reservation Agreement after the quarter ended.
The company expanded its backlog to a record $807 million, up 25% sequentially, driven by orders from four new and two repeat customers.
Eos secured $263 million in gross proceeds for Frontier Power USA, exceeding the joint venture's initial equity target and supporting more than $1 billion of deployable project capital.
Commercial production launched on Line 2 at the Thorn Hill facility, achieving an initial 10% improvement in battery cycle time compared to Line 1, with further optimization expected as production ramps.
What management expects
Eos tightened its full-year 2026 revenue guidance to $300 million to $350 million, from the prior range of $300 million to $400 million.
The revised outlook reflects the company's evaluation of the timing associated with consolidating its production lines into a single manufacturing footprint in Thorn Hill.
The consolidation initiative is expected to improve manufacturing efficiency, optimize capacity utilization, enhance margins, and strengthen the company's long-term operating profile.
Key risks
New Eos' minority investment in Frontier Power USA exposes the company to new risks related to project development, financing, permitting, construction, operations, and asset ownership, which are outside its historical business and may be difficult to predict or manage.
New Because Eos does not control Frontier Power USA, it may have limited ability to influence decisions affecting the value of its investment, and changes in FPUSA's business or governance could require different accounting treatment, potentially impacting Eos' financial statements and results.
Eos has a history of net losses and negative operating cash flows, and may continue to incur losses and require outside capital if it cannot achieve sustained profitability and scale manufacturing efficiently.
The company’s relatively recent commercialization and limited manufacturing experience make it difficult to predict future prospects, and any failure to deliver product benefits or improvements to competing technologies could reduce demand.
Eos is heavily dependent on third-party suppliers and contractors, and supply chain disruptions or quality control problems could adversely affect operations and financial results.
A substantial portion of Eos' future revenues, backlog, and growth strategy may depend on the ability of Frontier Power USA, a related party and major customer, to develop, finance, and operate energy storage projects, and any challenges faced by FPUSA could adversely affect Eos.

→At 3.1x sales, the market is paying 83% less than EOSE's own 5-year median of 17.8x. Pessimism is priced in - the question is whether it is deserved.
What this measures
What the market has paid for each dollar of earnings, sales or book value, every year, with today's multiple as the last point and the median drawn across.
What good looks like. There is no good level. What matters is the distance from the company's own history, and whether the business has changed enough to justify it.
If it rises or falls. A multiple above its own median means the market expects more than it used to, so more has to go right. Below the median means the opposite, and the question is whether the pessimism is deserved. A multiple can also fall because earnings rose, which is the good way.

→Every dollar of market value currently buys -63.4% of annual free cash flow, more than its 5-year median of -48.7% - the cash is cheaper than usual.
What this measures
Free cash flow divided by market value: the cash the business generates for every dollar you pay for it. The inverse of a price-to-cash multiple.
What good looks like. A yield at or above the company's own history, and one that compares well with what cash is worth elsewhere.
If it rises or falls. The yield rises when cash grows or the price falls, so a high yield is either a bargain or a warning about the cash continuing. Read it beside the cash conversion chart, which shows whether the cash is holding up.
What does “Value” actually mean?
Value asks what you pay for each dollar of earnings, sales or cash the business produces. A high multiple isn't automatically bad - fast growers earn theirs - but a price far above the company's own history means the market expects a lot to go right. We compare each multiple to the company's own past and to its sector, never to a universal rule.
not profitable: no free cash flow or earnings for the price to rest on

→Revenue reached $114M in 2025, compounding +85% a year since 2022 though the pace has cooled. The trailing twelve months are already running at $214M, ahead of the last full year.
What this measures
The money customers paid, before any costs are taken out. Each bar is one quarter or, on the annual view, a full financial year; the last annual bar may be the trailing twelve months, which the footnote marks.
What good looks like. Growth that repeats, rather than one strong year carrying the chart, and a trailing twelve months keeping pace with the last full year.
If it rises or falls. Revenue is the hardest line to flatter, so a rise is the most trustworthy kind of growth. A fall puts pressure on every margin below it, because costs rarely come down as quickly as sales do.

→The company lost $970M in 2025, more than the $686M it lost the year before. The losses are widening - check the Health chapter for how long the cash lasts.
What this measures
What is left after every cost, including tax and interest. The bottom line of the income statement.
What good looks like. Profit growing at least as fast as revenue, which means the business is keeping more of each sale as it gets bigger.
If it rises or falls. Profit can move for reasons revenue cannot explain - a one-off charge, a tax change, a write-down - so a single sharp year is worth checking against the margin chart before reading it as a trend.

◌ 2026 = trailing twelve months to the latest filed quarter (2026-06-30), not a full fiscal year · on the quarterly views, growth is the trailing twelve months against the twelve before, or a quarter against the same quarter a year earlier
→Revenue grew 534% over the twelve months to 2026-06-30, against an average of +582% a year over 2021-2025.
What this measures
How much revenue and earnings changed against the year before - the trailing twelve months against the twelve before them at each quarter, or one point per fiscal year. It is the speed of the business, not its size.
What good looks like. The earnings line above the revenue line: profits growing faster than sales means each new dollar of sales arrives more profitably than the last.
If it rises or falls. A high growth rate off a small base is easy and gets harder every year, so slowing growth in a large business is normal rather than a warning. Earnings falling while revenue grows is the combination worth understanding: costs are rising faster than sales.

→Revenue per share reached $0.44 in 2025, compounding +15% a year against +85% for EOSE as a whole. Dilution absorbed about 70.3 points of that growth. The trailing twelve months are running at $0.82 a share. Free cash flow per share stands at $-1.02.
What this measures
Revenue and free cash flow, each divided by the number of shares in issue and adjusted for splits so old and new years compare honestly. Both lines rising means each share owns more of the business's sales and cash.
What good looks like. Both lines rising, and revenue per share growing at least as fast as the company's total revenue, which the answer compares. Faster means buybacks are working for you; slower means new shares are absorbing part of the growth.
If it rises or falls. This is the line that actually reaches you. A company can grow revenue every year and still shrink your slice by issuing shares faster than it grows.
What does “Growth” actually mean?
Growth here is what the company has actually reported to the SEC - not a forecast. We look at the last year, the three-year pace, whether growth is speeding up or slowing down, and whether it's been consistent rather than one lucky year. Hatched bars are fourth quarters we derived from annual filings (companies file a full-year 10-K rather than a Q4 report).
Profitability is thin or negative. The growth isn't turning into money yet.

→Operating margin widened 1007 points to -227% since 2022. The bottom line is still negative: costs below the operating line eat what is left. EOSE doesn't tag a gross-profit line in its filings, so the chart starts at operating margin.
What this measures
What survives at three points on the way down the income statement: after the direct cost of the product, after the cost of running the company, and after everything.
What good looks like. Margins that hold or widen as the business grows. The level itself varies enormously by industry, so the shape over time tells you more than the number.
If it rises or falls. A widening margin means pricing power or costs under control. A compressing one means the opposite, and it compounds: on large revenue, two points of margin is a great deal of profit.

→The company generated -$211M of operating cash in 2025. With no profit to compare against, cash generation is the number that matters here.
What this measures
Reported profit against the cash the business actually collected from operating. Profit is an accounting judgement; cash is not.
What good looks like. Cash at or above profit, year after year. Depreciation and other non-cash charges usually push cash above profit, so roughly 100% or more is healthy.
If it rises or falls. Cash falling behind profit for more than a year is the classic early warning: the sales are booked but the money has not arrived, and it shows up in receivables and inventory. For a lender the comparison behaves differently, because a growing loan book consumes cash.

→Free cash flow is negative, so no share of revenue is currently converting to spare cash. Every sales dollar is being reinvested or consumed.
What this measures
Free cash flow as a share of revenue: how much of each dollar of sales survives both costs and capital spending.
What good looks like. A steady or rising share. Asset-light businesses convert far more than manufacturers, so compare a company with itself.
If it rises or falls. Falling conversion while revenue grows means growth is being bought with capital spending or working capital, which is fine while it lasts and painful when it stops.

→The biggest claim on each sales dollar is capital spending, at 47% of revenue (research and development 25%, stock compensation 22%). That share has fallen since 2022, so the cost of competing is easing.
What this measures
Capital spending, research and development, and stock compensation, each as a share of revenue. The three ways a business pays to keep its position.
What good looks like. A share that is stable or falling while revenue grows, which means the cost of competing is not rising with the business.
If it rises or falls. Rising intensity means each new dollar of sales is getting more expensive to win. Falling intensity can mean efficiency, or it can mean under-investment that shows up years later.

→EOSE's return on capital is negative at -35.0% in 2025. The capital in the business is not yet earning anything back.
What this measures
The same return as the card above, but every filed year, against a 10% line that stands in for what capital costs.
What good looks like. Years above the line, and a trend that is flat or rising rather than drifting down towards it.
If it rises or falls. A business earning above its cost of capital creates value by growing; one earning below it destroys value by growing. The 10% line is a convention, not a law, so read the distance from it rather than the crossing.
What does “Quality” actually mean?
Quality asks whether the growth makes real money. Margins show how much of each sale survives costs; return on equity shows what shareholders earn on their capital; and the profit-to-cash comparison catches companies whose accounting profits never turn into actual cash.

→Debt of $617M sits against $305M of cash. Earnings don't currently cover the interest bill at all.
What this measures
Total borrowings against cash on hand, with debt as a multiple of shareholders' equity, and how many times profit covers the interest bill.
What good looks like. Interest covered comfortably - roughly eight times or more - and debt that is not a large multiple of equity.
If it rises or falls. Debt is only a problem when it has to be repaid or refinanced in a bad year, so cover matters more than the amount. Rising debt with rising cover is a business borrowing to grow; rising debt with falling cover is the combination that ends badly.

→Near-term liquidity is comfortable: 3.3x of current assets for every dollar due within the year. That is stronger than in 2019.
What this measures
Current assets over current liabilities: what the company can turn into cash within a year against what it owes within a year.
What good looks like. Comfortably above 1.0, and not falling year after year. Below 1.0 means near-term bills exceed near-term resources, which is normal for some business models and a warning in others.
If it rises or falls. Inventory and receivables build it up; short-term borrowing and payables pull it down. A retailer that turns stock over quickly can run lower than a manufacturer and be perfectly sound.

→Operating profit does not cover the interest bill (-7.9x). Cover was -0.5x in 2019, so the margin of safety has narrowed.
What this measures
Operating profit divided by interest expense - how many times over the year's earnings could pay the year's interest.
What good looks like. High and steady. Five times is a common floor; comfortably above it means the debt is being carried, not merely serviced.
If it rises or falls. It falls when profit falls or when borrowing costs rise, and a company can look safe on the level while the direction is telling you otherwise.

◌ 2026 = trailing twelve months to the latest filed quarter (2026-06-30), not a full fiscal year · each quarterly point is the trailing twelve months to that quarter end, so the last one is the current figure
→EOSE's operations consumed cash rather than produced it over the last twelve months. Up from -4805.2% in 2019.
What this measures
Operating cash flow as a share of revenue: of every dollar sold, how much reached the bank before capital spending.
What good looks like. A high share, holding up or improving. It is the clearest sign that reported profit is real.
If it rises or falls. It falls when customers take longer to pay or stock builds up, and it can stay high while profit falls - which is usually the more reassuring of the two.
Shareholders' equity
Is EOSE's shareholder equity (book value) growing?
Equity is below zero after years of buybacks exceeding earnings, so debt-to-equity and return on equity are not published for EOSE: a ratio to a negative base means nothing.

→Shareholders' equity is negative at -$1.0B: liabilities exceed assets. Usually the mark of heavy buybacks or accumulated losses, and always worth understanding which.
What this measures
What would be left for shareholders if every asset were sold at its book value and every debt repaid. Book value, in other words.
What good looks like. Equity growing as retained profits build up, unless the company is deliberately returning more than it earns.
If it rises or falls. Equity falls for two very different reasons: buybacks, which return money to you, and losses, which do not. The distinction is the whole story, and negative equity means liabilities now exceed assets, which makes debt-to-equity and return on equity meaningless rather than alarming.
What does “Health” actually mean?
Health asks one question: can the business survive a bad year? We check whether near-term bills are covered, whether debt is modest and shrinking, whether earnings comfortably pay the interest, and - for loss-makers - how many years of cash are left at the current burn rate.
EOSE returns nothing to shareholders yet, and the share count keeps rising. Every dollar stays in the business.

→The share count grew 23.0% in 2025, averaging 64.5% a year over three years. Your slice of the company shrinks by that much each year unless earnings grow faster.
What this measures
The yearly change in the number of shares in issue, adjusted for splits so the years compare. A bar below zero is a falling share count, usually from buybacks; above zero, new shares were issued.
What good looks like. A flat or falling share count. Falling means each share you hold owns a little more of the business every year.
If it rises or falls. A rising count divides the same business among more owners, so your slice shrinks unless profits grow faster. This is the most direct chart on the page: it is your ownership, measured.
Dilution against what it bought
Has EOSE's revenue per share grown faster than its share count?
Change since 2019. The gap between the lines is what each share gained or lost. Share counts are split-adjusted weighted averages.

◌ 2026 = trailing twelve months to the latest filed quarter (2026-06-30), not a full fiscal year · on the quarterly view, revenue per share is the trailing twelve months over that quarter's diluted count
→EOSE's share count rose 6536% from 2019 to 2025 while revenue per share grew 247%. Holders are further ahead than before, though the gain per share is smaller than the growth in the business.
What this measures
The share count and revenue per share over the same years, both indexed to 100 at the start, so the two lines can be compared directly.
What good looks like. The per-share line above the share-count line: whatever the company did with its shares, more business ended up behind each one.
If it rises or falls. Issuing shares is not automatically bad. It is bad when the money raised buys less growth than the dilution cost, which is exactly what the gap between these two lines shows.
Why compare buybacks with stock compensation?
A company can trumpet billions in buybacks while quietly issuing nearly as much stock to employees. What matters to you is the net effect: is the share count actually falling? If not, the 'return' is mostly recycling.
→EOSE is in a downtrend: the price is below the cloud where recent trading settled and that cloud is still falling. Both shorter readings point down as well, so nothing here disagrees with the downtrend.
How the trend above is worked out
The trend read is the daily Ichimoku picture, the same indicator drawn on the chart above. Five names, and what each one is: the TENKAN is the midpoint of the last 9 sessions' high and low, the fast line; the KIJUN is the same over 26 sessions, the slow one; the two SENKOU spans are midpoints drawn 26 sessions into the FUTURE, and the band between them is the KUMO cloud - because it is drawn forward, the support for the coming weeks is already fixed and a change of its direction can be seen coming; the CHIKOU is today's close compared with the close 26 sessions back. A trend confirms itself in that order and the checks follow it: price clears the cloud, holds above both lines, the Tenkan crosses above the Kijun, the cloud ahead turns up, and the Chikou stands higher than the price a month ago. Six of six therefore means all of that at once; a price sitting inside the cloud, or below its own lines, cannot get there. The last check is the one Ichimoku cannot answer - whether the S&P 500 did better over 12 months (252 sessions), measured on the SPY ETF with dividends included, on the same adjusted basis as the stock's own price. Our figures are the last close we hold, refreshed every trading night; the chart is live. None of this says anything about the business, and it is not advice.
Are EOSE's insiders buying or selling shares with their own money?

→Since November 2023, insiders bought $841,840 and sold $26M on the open market, a net sale of $25M. A further 115 transactions were grants, option exercises or tax withholding, which say nothing either way.
What this measures
Open-market buys and sells by the company's own officers and directors, from their Form 4 filings. Grants, option exercises and shares withheld for tax are excluded, because they are compensation rather than decisions.
What good looks like. Buying with their own money, which is the one insider action that is hard to explain away.
If it rises or falls. Selling is weak evidence: insiders sell to diversify, to buy houses, and on pre-scheduled plans set months ahead. Buying is stronger evidence, because there is only one reason to do it. The absence of any buying over a long stretch is itself worth noticing.

Why do the transaction types matter so much?
Most insider filings are not trades: stock grants, option exercises and tax withholding are how executives get paid, and gifts are estate planning. The signal lives in open-market transactions - a buy means an insider chose to spend their own cash on the stock. Sells are murkier: many are pre-scheduled 10b5-1 plans set months in advance. That's why the chart counts only open-market activity, and the table labels every row.

Source: SEC Form 13F filings for the quarter to 30 June 2026, Schedules 13D and 13G, and Form 4. Shares on today's basis, value at the latest price.
Where does this list come from?
Fund managers with more than $100 million in US stocks report their holdings every quarter on Form 13F, up to 45 days after the quarter ends, so the fund figures are as of the last quarter end. A fund family reports as one manager, and funds together can report more than 100%: shares lent to short sellers are bought again by other funds, and both report them. Anyone holding more than 5% of a class files a Schedule 13D or 13G, and officers and directors report what they hold on Form 4 after every trade, so those rows carry their own dates. Short positions are not reported anywhere. A stake is the holder's shares as a share of all the company's shares, with other share classes converted at their market value.
