HomeBiogas 2025: Backlog Jumped, but the Cash and Execution Test Is Still Ahead

Getting to Know the Company

At first glance, HomeBiogas looks like a small product company that sells biogas systems to farmers and households. That is only a partial read. The model the company is trying to build today is no longer just a one-time system sale. It is a two-layer transaction: sell the system now, then try to monetize carbon rights generated by that system over many years. That is why the income statement is still small while the backlog suddenly looks enormous relative to the size of the company.

What is working now? 2025 looked better operationally. Revenue rose to $2.889 million, gross profit jumped to $1.05 million from $384 thousand in 2024, and the operating loss narrowed to $3.839 million from $9.518 million a year earlier. At the same time, the company cut headcount, reduced R&D sharply, and brought down commercial and overhead expense.

But this is still not a clean story. The company signed carbon agreements that pushed backlog to $43.054 million, of which $42.485 million is carbon rights, yet it ended the year with just $1.862 million of cash, negative operating cash flow of $2.246 million, and a clear going-concern note. The market therefore does not need to ask whether there is potential. It needs to ask whether the company can finance the road until that potential starts turning into invoices.

That is also what makes 2026 important. It is not a clean breakout year. It is a proof year. The company needs to show that three things happen together: regulatory approvals keep moving forward, actual installation pace increases, and the funding structure stops being the main bottleneck. Without all three, the large backlog will remain mostly a story about distant years.

On a first-screen basis, this is still a very small company. At a share price of 57.7 agorot and with 43.98 million shares outstanding, market value is roughly ILS 25 million. That sharpens the gap between today’s value and the economic promise implied by the carbon projects. It also means the route to bridging financing gaps through the capital markets could be expensive for shareholders.

A quick economic map

The message of those two charts is simple. The base business did not break, but it did not break out either. The big improvement came mainly from better gross profitability and lower expense, while the component that creates the huge backlog, carbon rights, is still small in reported revenue.

Events and Triggers

The first trigger: the Ghana project received technical approval from the Swiss environment ministry in early December 2025, and in February 2026 the company signed an amendment with Klik that allows up to $770 thousand of prepayment. That matters because it is the first time a carbon buyer is willing to advance cash without a discount. But it is still not free money. If the company does not deliver enough carbon rights to Klik by the end of September 2028, any unpaid balance has to be returned.

The second trigger: Kenya moved one stage forward. In December 2025 the company signed a binding agreement with Klik covering 17,000 systems in 2026 through 2028, with potential value of $13.3 million from carbon rights and another $6.8 million from system sales. In February 2026 it also received two LNO approvals from Kenya, one for the regulatory Klik project and one for migrating the existing voluntary project into a regulatory framework. That strengthens the thesis that the company is trying to move up the carbon value curve, from the voluntary market toward a regulatory one.

The third trigger: Rwanda moved from pilot territory toward possible commercialization. In October 2025 the company signed an agreement with the UN development program to supply systems worth about $360 thousand, and in January 2026 it added a more interesting layer: a memorandum of understanding with a global energy company around a Singapore government tender for carbon rights from the company’s Rwanda project. That is still not a binding commercial deal, but it shows that the company is no longer looking only for end customers for the systems. It is also looking for carbon buyers and project financiers.

The fourth trigger: in February 2026, Closed Loop sold shares, pushing the control group below the 25% voting-rights threshold and terminating the shareholder agreement and joint-control structure. This is not an operating event, but it changes the company’s power structure. On one hand, control became less rigid. On the other, one more layer of historical support weakened while the company still needs funding flexibility.

The fifth trigger: in December 2025 the company examined a convertible bond issuance, and the draft trust deed already included a debt-service reserve equal to one full year of interest, a dividend restriction and a negative pledge. Even if the issuance itself never happens, the protections that appeared in the draft are revealing. They suggest how the debt market is likely to read the company: not as a growth name raising debt to accelerate, but as a company that first needs to prove survival and repayment capacity.

What is interesting is that all of these events move in the same direction. The company is managing to create commercial traction around carbon, but every step forward arrives with layers of conditions, approvals, financing needs and obligations that prevent the story from becoming simple.

Efficiency, Profitability and Competition

The core of 2025 was operational improvement, not business breakout. Revenue rose by about 10%, but cost of sales fell by about 18%. That pushed gross profit to $1.05 million, and gross margin moved from about 15% in 2024 to about 36% in 2025. That is a material change, and it did not come only from volume. It also came from what the company did to its cost structure.

What really improved profitability

The first move was a sharp expense reset. R&D expense fell to just $252 thousand from $3.346 million in 2024, sales and marketing expense fell to $1.383 million, and general and administrative expense declined to $3.244 million. Part of the move reflects the fact that 2024 included a $1.496 million impairment tied to the institutional biogas system, but even after stripping out that noise it is clear the company no longer operates like a platform building a broad development engine.

The second move was a change in the sales model. In Kenya, until the end of March 2024, the company allowed end customers to pay in 24 monthly installments. From the second quarter of 2024, it moved to cash-only sales. That looks technical, but it changes revenue quality. Trade receivables fell to $515 thousand from $900 thousand in 2024, which means the improvement in cash conversion and working capital also came from tighter commercial terms, not only from healthier demand.

The third move was mix. In 2025, about 48% of revenue came from end customers, 42% from distributors, aid organizations and governments, and 10% from carbon-right sales. In 2024, end customers were 68% of revenue. In other words, the company did not just sell better. It also shifted weight toward channels that are more connected to projects and institutional orders.

What is still unproven

This is exactly where the yellow flag sits. Carbon, which is now the center of the strategic story, produced only $303 thousand of revenue in 2025. That is an improvement from $181 thousand in 2024, but still tiny relative to the backlog the company is presenting. Anyone reading the company mainly through backlog is therefore missing the fact that the reported P&L still relies overwhelmingly on system sales rather than on carbon monetization at scale.

Another important point is that the company impaired in 2025 the full capitalized carbon-rights costs tied mainly to the India project, $854 thousand. This is not just an accounting line. It is an admission that even when the company can identify a carbon opportunity, it does not always have the resources to carry it all the way into economic recognition. At the same time, all project costs recorded in 2025 in connection with carbon projects, mainly in Ghana and other territories, about $524 thousand, were expensed as incurred because they did not meet capitalization criteria. That illustrates the gap between future backlog and the company’s ability to carry a long development runway on its balance sheet.

Competition, concentration and product quality

The company operates in a market with local competitors, rigid systems, flexible systems and players such as Sistema.bio. Its stated advantage rests on a lightweight product package, stable gas pressure, easier installation and fit for developing markets. That is a useful technology edge, but not an impregnable moat.

On the operating side, one concentration risk is easy to miss: a single supplier in India, Shakti, already accounted for 70% of total procurement in 2025, up from 49.7% in 2024. The company says qualifying an alternative could take several months up to a year. That matters because at the point where the company wants to move from promise to rollout, such concentration stops being a technical issue and starts dictating pace.

On the positive side, customer concentration actually looks better. In 2025 there was no single customer representing more than 10% of sales, while there was such a customer in 2023. Geographically, Kenya led with $1.267 million, but the rest of revenue was spread across Israel, the United States, Rwanda, the UK and other markets. That does not solve project risk, but it does mean reported revenue is less dependent on a single customer than a superficial read might suggest.

Those charts sharpen two conclusions. First, the year was aggressively reset on costs. Second, the revenue base is relatively diversified, but that diversification still does not change the fact that the large step-up implied by the company’s narrative depends on a small number of regulatory carbon projects.

Cash Flow, Debt and Capital Structure

This section has to use the right frame. In HomeBiogas’s case, the main story is not normalized cash generation. It is all-in cash flexibility. In other words, how much cash is actually left after real cash uses, including operating burn, lease cash and other obligations.

The real cash bridge

The group ended 2025 with $1.862 million of cash, down from $2.837 million at the end of 2024. Operating cash flow was negative $2.246 million. Investing cash flow was positive $280 thousand, mainly because of lease receivable collections and restricted cash release, and financing cash flow was positive $943 thousand, mainly thanks to private placements that brought in $1.263 million.

So even after a deep efficiency year, the business still burned cash at a pace that does not allow the company to grow without outside sources. This is not a theoretical conclusion. If the $1.263 million injected through private placements in June and July 2025 is stripped out, year-end cash would have fallen to roughly half a million dollars.

That is the core picture. The company did not close the funding gap through operations. It only reduced it.

No heavy bank debt, but real financing pressure

On one hand, the balance sheet is not loaded with classic bank debt. Group liabilities are mainly leases, payables, deferred income and the government-grant liability. The government-grant liability stood at $516 thousand at year-end, and the company continues to pay royalties to the Israel Innovation Authority. In leverage terms, this is not a threatening capital structure.

On the other hand, precisely because there is no large bank-debt layer, any funding pressure falls back on equity, future prepayments or hybrid instruments. The draft convertible-bond process from December 2025 makes that very clear. Anyone trying to open a debt channel already had to accept, at the draft stage, a debt-service reserve, a dividend restriction and a negative pledge. That is not necessarily a problem by itself, but it does show that the company approaches the debt market from a relatively weak bargaining position.

Better working capital, but not a misleadingly clean picture

The company reported current assets exceeding current liabilities by $2.12 million. That is real, but it is easy to overread. A current-asset surplus is not the same thing as funding flexibility, especially when part of those current assets is receivables and inventory rather than cash.

In addition, part of the working-capital improvement came from tighter customer-credit terms in Kenya and from a narrower activity footprint. That is important progress, but it is not a substitute for proving that the company can fund Ghana, accelerate regulatory Kenya and maintain installation pace without once again leaning on external capital.

Even internal support looks less comfortable

At the end of 2025 the company carried about $85 thousand of payables to controlling parties, with maturity deferred to support liquidity. In addition, in August 2025 two former joint controlling shareholders who also serve as officers undertook not to draw management fees if the 12-month budget did not allow continuing current operations. But on the very day the financial statements were approved, March 9, 2026, the board received notice cancelling that undertaking. It sounds like a small point, but it tells an important story: the company cannot assume that internal support mechanisms will stay open indefinitely.

That chart highlights the gap between two stories. One story says the company learned how to burn less cash. That is true. The second story says the company is already out of dependence on external funding. That is still not true.

Outlook and What Comes Next

The first finding: HomeBiogas’s backlog looks large, but it does not resemble a normal industrial backlog. As of December 31, 2025, backlog stood at $43.054 million, of which $42.485 million was carbon rights. In other words, almost all of it depends on regulatory mechanisms, future installations and revenue recognition over time.

The second finding: even within that backlog, the near-term portion is modest. The schedule shows $854 thousand in 2026, $2.508 million in 2027 and $7.247 million in 2028. The remaining $32.52 million sits in 2029 through 2031. The implication is straightforward: most of the value being presented today sits in the far years, while funding is needed now.

The third finding: the Klik agreements in Ghana and Kenya are real progress, but both include adjustment, cancellation or approval dependency. In Ghana, as of the approval date of the annual report, the required approvals had still not been fully obtained, so the agreement remained cancelable from Klik’s side. The company says it has understandings with Klik to continue the cooperation, but that is still not an environment of full certainty.

The fourth finding: the company already acknowledges that not every carbon project makes it all the way through. India is the reminder. After capitalizing costs tied to that project, it wrote them all off because it lacked available resources to complete the rollout. So the key forward question is not only how many projects can be signed. It is how many can actually be financed, operated, monitored and approved all the way to monetization.

2026 is a proof year, not a breakout year

If the coming year needs a label, it is not a breakout year. It is a proof year. The company is no longer judged only on selling systems. It is judged on whether it can convert carbon backlog into a combination of approvals, installations, prepayments and future revenue recognition.

In Ghana, the company had already installed about 170 systems by the report approval date, surveyed more than 1,000 farms, and signed a Klik agreement that could reach $28.8 million through 2030 with another $17.5 million of option value from 2031 onward. But the company itself also says explicitly that the ability to deploy systems and recognize revenue depends on obtaining financing. That is management’s way of saying, without saying it directly, that the contract does not solve the bottleneck. It only defines the possible payoff if the bottleneck is removed.

In Kenya, the potential may look even cleaner, because alongside the $13.3 million of carbon-right value there is another $6.8 million of possible system sales. Still, even here the approval received is an early-stage approval, not a finish line. Investors need to distinguish between a meaningful improvement in probability and revenue that has already started to flow.

In Rwanda, the company may benefit from a more interesting commercialization path: a UN project, a preliminary approval already in place, and a Singapore government tender that could open the door to state-level carbon monetization. That makes Rwanda more than just an installation geography. It becomes a broader commercial proof point. But even here, the current status is still tender process and commercial potential, not signed cash.

What the market is likely to measure in the next reports

The first thing the market will check is whether the Klik prepayment actually arrives, and at what pace. Not because the $770 thousand by itself changes everything, but because it indicates whether a strategic buyer is willing to fund the path to project delivery.

The second thing is actual installation pace, not just signatures. In Ghana and Kenya, the critical number is rollout pace, because that is the base for all future credits.

The third thing is funding structure. Any announcement about equity, debt, a strategic partner or an expanded pre-sale mechanism will matter more than a small move in current system sales, because the market already understands that the main bottleneck today is not end-market demand. It is execution financing.

The fourth thing is the quality of conversion from the voluntary market to the regulatory market. If Kenya advances there, the company will not only increase the scale of credits. It may also improve realized pricing per unit. This is one of the few places where regulatory progress could materially change project economics without an immediate step-up in fixed costs.

This is the most important chart in the report. It explains why the story is impressive, but also why it still does not create comfort. Most of the value being presented today sits far out in time, while the cash needed to keep the company alive lives much closer.

Risks

The first risk, funding and execution. Management itself says existing cash and resources are not sufficient to support operations in their current format. Anyone looking at backlog without putting that sentence at the center is reading the company incorrectly.

The second risk, backlog quality. The company explicitly says that the ability to supply orders and recognize revenue depends on obtaining financing for project setup and execution. That means carbon backlog should not be read as if it were a standard product order ready to ship from inventory.

The third risk, regulatory approvals. In both Ghana and Kenya, the route runs through Article 6 mechanisms, corresponding adjustments, bilateral arrangements and host-country climate commitments. Those are not technical footnotes. They are the switch between theoretical backlog and realized revenue.

The fourth risk, a prepayment that is both a lifeline and an obligation. The Klik prepayment can help fund Ghana, but if enough rights are not delivered by September 2028, the money must be repaid without interest. In other words, this is not permanent capital. It is bridge financing with an embedded performance test.

The fifth risk, currency exposure. At the end of 2025 the company had financial assets denominated in currencies other than the functional currency totaling $798 thousand and financial liabilities totaling $1.655 million. Management says it made adjustments that improve the natural hedge, but the bottom line is that there is still an FX gap that can move results and cash flow.

The sixth risk, supply chain. Dependence on one supplier for 70% of procurement is a real risk, especially in a period when the company is trying to turn pilots into broad deployment.

The seventh risk, management support is not guaranteed. Deferred management-fee withdrawals helped liquidity, but the cancellation of the undertaking by two officers on the approval date of the report is a reminder that even internal support is temporary and conditional.

Conclusions

HomeBiogas looks much more orderly operationally than it did a year ago. Gross profitability improved, expenses fell, and the company built a set of regulatory carbon contracts that creates a real commercial horizon around carbon. But the main blockage has not been solved: the move from a large future backlog to actually financed projects installed at the required pace.

The current thesis in one sentence: the company has already shown that it can build a commercial story around carbon rights, but it has not yet shown that it can finance and execute that story at a pace that justifies the backlog it is presenting.

What changed versus the earlier understanding of the company is mainly two things. First, the operating story is cleaner because of lower expense and a better margin profile. Second, the carbon story no longer rests only on aspiration. It now rests on binding agreements, preliminary approvals and a possible prepayment. Still, the strongest counter-thesis remains intact: the company may be making real commercial progress, but the gap between funding timing and revenue-recognition timing is still too wide, so additional growth may continue to depend on equity raises, payment deferrals or bridge financing.

What could change the market’s read in the short to medium term is not another MOU headline, but a sequence of three proofs: cash coming in, systems getting installed, and carbon rights moving into monetization. If those three begin to appear together, the read on the company can change. If one of them stalls, especially funding, backlog will once again look like a distant promise.

Why does this matter? Because HomeBiogas is trying to build a model that could be high quality if it works: sell a physical product and create a long-tail income stream from the same installed base. But until that link turns from paperwork into recurring cash, business quality will continue to be judged less by the size of the ambition and more by execution discipline and financing discipline.
