Ascent Solar Technologies, Inc. Common Stock (ASTI): fair value, margin of safety and Wheel Score
Ticker symbol ASTI · Energy · Solar · United States · Speculative
Is ASTI undervalued?
At 1.73 (close of 5 Nov 2026), ASTI trades 331% over the GLS average fair value of 0.4010, with 0 of 1 models above the price. The stock earns none of the Wheel Score's Value points at this price. That is a statement about price against trailing fundamentals, not about the company's prospects - the Wall Street View and the Growth tab on the Quote page carry the forward numbers.
The average is built from just 1 models (DCF) - the rest returned nothing because an input they need (dividends, free cash flow, book value) is zero or negative - so treat it with more caution than usual.
The nightly engine files ASTI under Speculative - it is losing money or its Piotroski health score is 3 or lower - which caps its Wheel Score at 45 and keeps it out of the Sunday Scan.
Nine valuation models for ASTI
Each model turns the latest filed numbers into a value per share; the GLS fair value is the simple average of the ones that produce a positive number. The last two rows are shown for reference and never enter the average. The Quote page lets you switch any model off and add your own margin of safety.

| Graham Number | - | - | The most a defensive investor pays for the earnings and book value per share; no value tonight |
| Graham Growth | - | - | Graham's growth formula: EPS × (8.5 + 2 × growth), adjusted for bond yields; no value tonight |
| Lynch | - | - | EPS × the earnings growth rate (PEG of 1), growth capped at 25%; no value tonight |
| GLS Growth | - | - | EPS compounded ten years at the blended growth rate, discounted back at 15% a year; no value tonight |

Quality and financial health
Ascent Solar Technologies, Inc. Common Stock scores only 3 of 9 on the Piotroski F-score, which fails the "Piotroski 6 or more" Wheel Trade Filter. A reading this low means several of the basic tests - positive earnings, positive operating cash flow, falling debt, no new share issuance - are not met. A GLS Moat score of 1.6/10 is a weak reading: the accounts do not show returns and margins that competitors have been unable to wear down, so the Moat part of the Wheel Score contributes little.
Returns on capital are thin or negative - ROIC -163.1%, ROE -234.7%, ROA -123.7% - with debt at 0.44 times equity and negative free cash flow.
Ascent Solar Technologies, Inc. Common Stock pays no dividend, so the DDM model does not apply and a covered-call holder earns only the premium and any price gain. Revenue comes mainly from Milestone And Engineering Arrangement 100% (quarter Q1 FY2026).
Institutional ownership scores 3/10, insider activity 3/10 and Congressional trading 5/10 on the GLS smart-money scales.
| Piotroski F-score | 3 / 9 | ROIC | -163.1% |
|---|---|---|---|
| GLS Moat | 1.6 / 10 | ROE | -234.7% |
| Debt / equity | 0.44 | ROA | -123.7% |
| Free-cash-flow yield | -43.6% | Payout ratio | 0% |
| Institutions | 3 / 10 | Insiders · Congress | 3 · 5 / 10 |
Wheel Score 9: Weak
With a Wheel Score of 9 Ascent Solar Technologies, Inc. Common Stock sits in the Weak band. It fails filter 2, a real business, not a gamble - speculative (a loss, or a weak Piotroski score); and filter 3, below fair value - trades 331% above our fair value; and filter 4, financially healthy - Piotroski 3/9 (under 6); and filter 7, a premium worth selling - implied volatility 230% (over 80%); and filter 8, big enough - market cap $17M (under $1.0B); and filter 9, not a penny stock - price 1.73 (under $5); Value (weak) is its weakest part.
Implied volatility is 230%, above the 80% ceiling of the Wheel Trade Filter on premium. The premium looks generous, but moves of that size can blow through any strike. Chain open interest is thin - 1,887 contracts across every expiry - so fills at a fair price are not guaranteed; a 30-45-day put may not exist at a usable strike.
Volume runs at 727k shares a day on a market cap of $17M, with a beta of 2.37 - a high beta, so the stock tends to move more than the market and a strike can be gapped through; the Stability part of the Wheel Score rates that weak.

| 4 | Financially healthy | Fails | Piotroski 3/9 (under 6) |
| 5 | Can repay its debt | Passes | Long-term debt repaid from 3 years of operating cash flow or less (6 for real estate and utilities; banks and insurers are not judged on it) |
| 6 | No serious red flags | Passes | Red Flags score 60 or more out of 100 (earnings, margins, debt, analysts, filings and price checked the same way for every stock) |
| 7 | A premium worth selling | Fails | implied volatility 230% (over 80%) |
| 8 | Big enough | Fails | market cap $17M (under $1.0B) |
