Ascent Solar Technologies, Inc. Common Stock (ASTI): fair value, margin of safety and Wheel Score
Energy · Solar · United States · Speculative / Distressed
Is ASTI undervalued?
At 1.89 (close of 16 Oct 2026), ASTI trades 364% over the GLS average fair value of 0.4076, 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 / Distressed - negative earnings or a Piotroski score of 3 or less - which caps its Wheel Score at 45 and keeps it out of the Sunday Scan.

Quality and financial health
Ascent Solar Technologies, Inc. Common Stock scores only 3 of 9 on the Piotroski F-score, which fails the Sunday Scan's "6 or more" rule. 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 1.1/10 is a weak reading: the ten-year history the score grades (revenue, EPS, book value, margins, cash flow, share count, ROIC) has not been steady, 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 1/10, 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 | 1.1 / 10 | ROE | -234.7% |
| Debt / equity | 0.44 | ROA | -123.7% |
| Free-cash-flow yield | -39.9% | Payout ratio | 0% |
| Institutions | 1 / 10 | Insiders · Congress | 3 · 5 / 10 |
Wheel Score 18: Weak
With a Wheel Score of 18 Ascent Solar Technologies, Inc. Common Stock sits in the Weak band. The parts - Value 0/25, Health 7/20, Moat 2/15, Premium 5/20, Stability 5/20 - show where: Value (0/25) scores lowest.
Implied volatility is 183%, far above the range the wheel strategy is built for. The premium looks generous; the Wheel Score gives it only 5 of 20 Premium points because moves of that size can blow through any strike. Chain open interest is 2,173 contracts across all expiries - enough for the wheel at normal size.
Volume runs at 303k shares a day on a market cap of $19M, with a beta of 2.35 - 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 gives that 5 of 20.
| Part | Points | From | |
|---|---|---|---|
| Value | 0 / 25 | -364% margin of safety | |
| Health | 7 / 20 | Piotroski 3/9 | |
| Moat | 2 / 15 | moat 1.1/10 | |
| Premium | 5 / 20 | implied volatility 183% | |
| Stability | 5 / 20 | 303k shares/day, $19M cap, beta 2.35 |
