Gibraltar Industries, Inc. (ROCK): fair value, margin of safety and Wheel Score
Industrials · Manufacturing - Metal Fabrication · United States · Speculative / Distressed
Is ROCK undervalued?
ROCK closed at 36.68 on 16 Oct 2026, which is 11% above the GLS average fair value of 32.98 from 2 models. 2 of them value the shares below today's price. Our screens read that as "no margin of safety": the stock is not a value candidate at this price, whatever the quality numbers say.
The average is built from just 2 models (DCF, 10 Cap) - 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 ROCK 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.
Nine valuation models for ROCK
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.
| Model | Value | vs price | What it measures |
|---|---|---|---|
| DCF | 33.42 | -9% | Present value of the projected free cash flows, discounted at the cost of capital |
| 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 |
| 10 Cap | 32.55 | -11% | Owner's earnings (operating cash flow less maintenance capex) capitalised at 10% |
| Payback Time | - | - | Eight years of compounded free cash flow: the price at which the business pays for itself; no value tonight |

Quality and financial health
Gibraltar Industries, Inc. scores only 2 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. On durability ROCK scores 5.6/10 on the GLS Moat - a middle reading; the Scorecard on the Quote page's Financials tab shows which ten-year lines are steady and which are not.
Returns on capital are moderate - ROIC 9.3%, ROE 10.3%, ROA 7.0% - with debt at 0.11 times equity and a free-cash-flow yield of 3.9%.
Gibraltar Industries, Inc. 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 Residential 84%, Agtech 12%, Infrastructure 5% (quarter Q2 FY2026).
Institutional ownership scores 10/10, insider activity 10/10 and Congressional trading 5/10 on the GLS smart-money scales.
| Piotroski F-score | 2 / 9 | ROIC | 9.3% |
|---|---|---|---|
| GLS Moat | 5.6 / 10 | ROE | 10.3% |
| Debt / equity | 0.11 | ROA | 7.0% |
| Free-cash-flow yield | 3.9% | Payout ratio | 0% |
| Institutions | 10 / 10 | Insiders · Congress | 10 · 5 / 10 |
Wheel Score 45: Weak
With a Wheel Score of 45 Gibraltar Industries, Inc. sits in the Weak band, capped at 45 because the engine files it as Speculative / Distressed. The parts - Value 8/25, Health 4/20, Moat 8/15, Premium 20/20, Stability 12/20 - show where: Health (4/20) scores lowest.
Implied volatility is 55% on the near-the-money contracts 20-60 days out - inside the 35-60% range the Wheel Score pays full marks for: enough premium to be worth selling, not so much that the risk is unpaid. Chain open interest is thin - 775 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 458k shares a day on a market cap of $1.1B, with a beta of 1.24 - 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 12 of 20.
| Part | Points | From | |
|---|---|---|---|
| Value | 8 / 25 | -11% margin of safety | |
| Health | 4 / 20 | Piotroski 2/9 | |
| Moat | 8 / 15 | moat 5.6/10 | |
| Premium | 20 / 20 | implied volatility 55% | |
| Stability | 12 / 20 | 458k shares/day, $1.1B cap, beta 1.24 |
