Is CETY a Buy or a Sell? The Bull and Bear Case (2026)
Last updated July 2026
Short answer
Both cases are real, which is why the question is contested. The bull case for Clean Energy Technologies (CETY) rests on ORC waste-heat-to-power niche: CETY's Clean Cycle ORC generator captures low-grade industrial waste heat and turns it into electricity, a real efficiency and decarbonization need across cement, steel, glass, oil and gas, and geothermal. The bear case rests on cETY is a highly speculative micro-cap and the risks are severe. We do not give a verdict. What follows is each case at full strength, so you can decide which set of assumptions you actually believe. Walnut is not an investment adviser.
Clean Energy Technologies, Inc. (CETY) is a small clean-energy technology company headquartered in Irvine, California, that designs and sells systems to turn wasted heat and waste materials into usable power. Its core products are Waste Heat Recovery Solutions built around the patented Clean Cycle generator, an Organic Rankine Cycle (ORC) machine that converts low-grade heat from industrial processes into electricity, and Waste-to-Energy solutions under its HTAP pyrolysis platform, which converts biomass and organic waste into renewable gas, power, and biochar. The company also pursues battery energy storage (BESS) projects and targets sectors such as cement, steel, glass, oil and gas, biomass, anaerobic digestion facilities, and, more recently, data centers. The reality behind the technology story is a very early-stage, thinly capitalized business. Reported revenue is tiny (roughly $2 million in 2025, down from the prior year) while losses widened, so the company is far from profitable and its pipeline is dominated by letters of intent, memoranda of understanding, and pilot-scale deals rather than large recurring contracts. Recent developments include an LOI with Hoppy Power for an HTAP waste-to-energy pilot in Alberta, a development MOU with METIS Power for a modular waste-to-energy platform, regulatory progress on a renewable gas project in Vermont, and a battery-storage project in New York. Importantly, CETY received Nasdaq deficiency notices in 2026 for failing to timely file its annual and quarterly reports, which does not immediately halt trading but creates a real path to delisting if not resolved. This combination of intriguing technology and severe financial and compliance fragility defines the stock.
The bull case for CETY
1. ORC waste-heat-to-power niche
CETY's Clean Cycle ORC generator captures low-grade industrial waste heat and turns it into electricity, a real efficiency and decarbonization need across cement, steel, glass, oil and gas, and geothermal. The company has installed prior-generation units many times over the years and is enhancing larger-scale systems. Demand for on-site clean power is a genuine tailwind, if CETY can convert interest into repeat orders.
2. HTAP waste-to-energy platform
The HTAP pyrolysis platform converts biomass and organic waste into renewable natural gas, power, and biochar, and CETY has pitched it for anaerobic digestion facilities to boost RNG output. Management has floated large per-installation value figures, but these are illustrative and depend on feedstock, scale, and regulatory approvals. The platform is the company's biggest growth narrative and its biggest execution question.
3. Partnerships and project pipeline
CETY's growth strategy runs through partnerships and early-stage deals: an LOI with Hoppy Power for an Alberta pilot, an MOU with METIS Power for modular units, a Vermont renewable gas project clearing regulatory steps, and a New York battery-storage project. These validate interest, but LOIs and MOUs are non-binding and pilot-scale, so the key is how many convert into signed, revenue-generating contracts.
4. New end-markets including data centers
CETY has signaled intent to develop energy-efficient solutions for AI data centers and crypto miners, tapping into surging power demand from computing. Positioning ORC and distributed-generation technology toward data centers is an on-trend narrative that could expand the addressable market. As with its other initiatives, the opportunity is early and unproven at commercial scale.
The bear case for CETY
CETY is a highly speculative micro-cap and the risks are severe. Revenue is tiny (around $2 million in 2025) and falling, losses are widening, and the company is not profitable, so it likely depends on external financing that can dilute shareholders. In 2026 it received Nasdaq deficiency notices for failing to timely file its annual (10-K) and quarterly (10-Q) reports; while trading was not immediately halted, unresolved non-compliance could lead to delisting, potentially by late 2026, which is a serious and specific risk. Much of the pipeline consists of non-binding LOIs and MOUs and pilot-scale projects that may never scale into meaningful recurring revenue. The stock is thinly traded and extremely volatile, and micro-caps like this can move violently on single press releases. Investors should treat a position as money they can afford to lose entirely.
The bear case deserves the same attention as the bull case, and usually gets less. If you are holding CETY already, the question is not whether these risks exist but whether any of them has moved from possible to actually happening in the reported numbers.
Where analysts land on CETY
Too few analysts publish on CETY for a consensus target to mean anything, so there is no professional average to weigh against your own view. That cuts both ways: less informed opinion to lean on, and less of it already priced in. The CETY forecast page covers what coverage does exist.
How is CETY valued? (as of Jul 2026)
Snapshot for CETY as of July 2026, sourced from Yahoo Finance and may be delayed. Valuation figures move with price and earnings; verify the current numbers with your broker before deciding.
- Revenue trend: Very small and declining; roughly $2 million in 2025, down about 11% year over year (approximate, verify live)
- Profitability: Unprofitable with widening losses; 2025 net loss was materially larger than 2024, so no positive earnings to value against
- Balance sheet: Thinly capitalized; likely reliant on external financing that can dilute existing shareholders (verify the latest filing)
- Market cap tier: Micro-cap / speculative; verify the current figure live because the low-priced share moves sharply
- Listing status: Nasdaq-listed but received 2026 deficiency notices for late 10-K and 10-Q filings; delisting risk if not cured (possibly by late 2026)
- Valuation note: Standard earnings multiples do not apply because there are no profits; the stock trades on story, pipeline, and financing news
All figures are approximate and tied to the asOf date; because CETY has had late regulatory filings, published financials may be dated, so verify the latest available numbers and filings before acting. With negligible revenue and ongoing losses, price-to-earnings and similar ratios are meaningless here. The stock is valued on narrative (technology, partnerships, pipeline) and on the market's read of financing and delisting risk, not on current fundamentals. Treat any position as high-risk speculation.
How do you decide if CETY is a buy?
Rather than asking whether CETY is a buy in the abstract, it tends to help to answer four questions:
- Thesis: do you believe the bull case above, and is it still true today?
- Time horizon: a single stock can be volatile, so a longer horizon absorbs more of the swings.
- Position sizing: a thesis can be right and the sizing still wrong; decide how much of your portfolio one name should be.
- Overlap: check whether you already hold CETY indirectly through an index or sector ETF before adding more.
What would change your mind on CETY
Write the tripwires down before you need them. Deciding what would falsify your view is far harder once a position is moving against you.
- Bull case breaks if: ORC waste-heat-to-power niche stalls in the reported numbers rather than in the narrative around them.
- Bear case breaks if: cETY is a highly speculative micro-cap and the risks are severe fails to materialise over several reporting periods while the drivers keep compounding.
- Neither matters if: the position has grown large enough that being wrong would damage the whole portfolio. Sizing overrides the argument.

FAQ
Is CETY a good stock to buy right now?
+
That depends on which case you find more convincing, and both are on this page. The bull case rests on ORC waste-heat-to-power niche, with revenue trend at Very small and declining; roughly $2 million in 2025, down about 11% year over year (approximate, verify live). The bear case rests on cETY is a highly speculative micro-cap and the risks are severe. If you believe the thesis, the real questions become sizing and overlap rather than timing. Walnut is not an investment adviser and this is not a recommendation.
Should I sell CETY?
+
Nobody can answer that for you, and the honest version of the question is narrower: has anything changed in the reason you bought it? The bear case on this page is the place to check. CETY is a highly speculative micro-cap and the risks are severe. If that risk is what you were worried about and it is now playing out, that is a real signal. If the price simply fell while the thesis held, that is a different situation entirely. Walnut is not an investment adviser.

What would have to change for CETY to stop being worth holding?
+
Decide that in advance, because it is far harder to think clearly once a position is moving against you. The concrete tripwires here: the driver behind the bull case (ORC waste-heat-to-power niche) stalling in the reported numbers rather than in the narrative, the risk above (cETY is a highly speculative micro-cap and the risks are severe) turning from a possibility into a reported fact, or the position growing large enough that a bad outcome would matter to your whole portfolio regardless of who is right.
Is CETY a good stock to buy right now?
+
That depends on your goals, time horizon, and risk tolerance, and this is not investment advice. The bull case is interesting clean-energy technology (ORC heat recovery and HTAP waste-to-energy) and a growing list of partnerships and pilots. The bear case is severe: tiny and falling revenue, widening losses, likely dilution, and Nasdaq deficiency notices that create real delisting risk. This is speculative money-you-can-lose territory, not a core holding.
What does Clean Energy Technologies actually do?
+
CETY designs and sells clean-energy hardware. Its main products are Waste Heat Recovery systems built on the patented Clean Cycle ORC generator, which turns industrial waste heat into electricity, and Waste-to-Energy systems under its HTAP pyrolysis platform, which convert biomass and organic waste into renewable gas, power, and biochar. It also pursues battery energy storage projects and targets sectors from cement and steel to data centers.
Why is CETY at risk of being delisted?
+
In 2026 CETY received Nasdaq deficiency notices for failing to file its annual report (Form 10-K) and a quarterly report (Form 10-Q) on time, which breaches Nasdaq listing rules. The notices did not immediately halt trading, but the company must submit compliance plans and file the reports; if it fails to regain compliance within the allowed window, potentially by late 2026, Nasdaq could move to delist the stock.
