Fair Value models
Bear¥51.27Fair Value ¥86.14Bull¥182.39
Price ¥79.89 · Upside +7.8%
Model ⓘEach model values the company its own way (discounted cash flow, earnings, assets, dividends). The fair value above starts from their evidence-weighted blend, not from a single model. In cyclical trough or peak years, after dilution or a stock split it is adjusted afterwards, so it can sit above or below the models. Based on fiscal year 2025 figures (about 10 months old). Earnings retained since then (¥0.4790 per share) are deliberately not added.Bear ⓘBear = the cautious scenario: the same model computed with conservative anchors (lower growth, margins and valuation multiples). Together with Bull it frames a plausible valuation range, not a price target.BaseBull ⓘBull = the optimistic scenario: the same model computed with favourable anchors (higher growth, margins and valuation multiples). Together with Bear it frames a plausible valuation range, not a price target. If a model's bull case is above four times its base value, the table shows that limit with a > sign (like the overall Bull above): beyond it no assumption holds.Coverage ⓘCoverage = how well-backed THIS model's estimate is for this stock (0–100): how complete and reliable its input data are, and how well the model fits the company. The final Fair Value is an evidence-weighted blend, so better-evidenced models count more. Green ≥70, amber 50–69, grey below 50.
Growth Quality ⓘGrowth is valuable only when reinvestment earns attractive returns (Aswath Damodaran): sustainable growth depends on return on capital, reinvestment and efficiency. Basis: total company revenue over the periods shown on the cards (3Y/5Y/all years), not per share, so a merger can show up as a growth jump; per-share earnings growth is in the value-creation card.100/100

+9.1%
Revenue growth 3 years ⓘMeasures the company's TOTAL revenue from reported annual statements: compound average growth per year (CAGR) from the fiscal year 3, 5 or N years back to the most recent comparable fiscal year. Not per share: buybacks do not change this number, and a merger can appear as a growth jump. Per-share growth (which does include buybacks) is in the value-creation card.

What shareholders gained per year (last 5 years) (mathematically smoothed) ⓘWhat the business itself delivers per year: earnings growth per share plus the dividend yield. This is what you get IF the market keeps valuing the stock the same way: it contains no assumption about the market changing its mind. Computed per share, so buybacks count and a merger does not pass as growth. For a company that pays no dividend it is pure earnings growth per share. Period: earnings growth per share as CAGR over the last 5 reported fiscal years (annual statements), plus the current dividend yield. The start value is the median of the three years around the start, so a single crisis year (a pandemic or a write-down) does not distort the rate. Smoothed = median of all growth paths between the years of the window (trend line on the logarithm of earnings per share): a single extreme year cannot distort the rate. The reported figure stays in the tooltip.

2025 sits 63% above its own trend. The rate follows the median trend of the last 5 years, not that single year.

Growth Forecast
Little optimism in the price
The price assumes less growth than the company has delivered so far and less than analysts expect.
What the price assumes ⓘThis turns our valuation around: instead of asking what the share is worth, it asks what growth the current price requires. It uses the cash the company keeps after all spending (free cash flow), the same discount rate as our models, five years of growth, then slowing evenly to 2 % a year by year ten. Compared with the analysts' sales forecasts extended to the same five years (at least three analysts, for context only, it does not enter the Fair Value): within 3 percentage points counts as "in line" (amber), below that little optimism (green), above that a lot of optimism (red).
+11.3%
Yearly growth needed for the next five years to justify today's price.
What forecasts expect ⓘAnalysts publish sales forecasts for the next two fiscal years. For the years after that, growth slows evenly to 2 % a year by year ten (2 % is the long-run rate our models use). Projected years are marked as such.
+29.7%
Yearly sales growth analysts expect, extended to five years.
The revenue jump in 2026 (+84.7%) comes with 40% more shares (acquisition or merger paid in stock). Per share it is about +31.8%. The comparison above is unreliable in such a year.
After inflation (China: IMF forecast 1.7% a year to 2030, 1.4% from 2016 to 2025) that is about +9.4% a year for the price and +27.6% for the forecasts.
AI conclusion: Strong synergies between inverters and surging battery pack sales form the main strength while thin evidence and absent durability signals remain the key weakness.
Main risk: Named competitors such as Sungrow, Huawei and Growatt offer hybrid inverters and storage systems at competitive prices, which could squeeze Deye's margins on residential and commercial energy storage products.
Bull case: By leveraging its battery flexibility and AI energy management tools like Deye Copilot the company could strengthen its position against rivals and expand in growing storage markets.
Bear case: If price competition intensifies and legal or trade issues restrict key products the company might see squeezed margins and slower growth in its core inverter and storage segments.
Ningbo Deye's preannouncement shows nearly 80 percent profit growth for the first nine months, fueled by strong sales of residential and commercial energy storage products. Battery pack revenue has surged to nearly match inverters, creating clear synergies in bundled solutions. Our models see the business as undervalued. Does the market overlook these integrated growth drivers, or do sector headwinds justify the caution?
