Garage Sale — A Hidden Play on Commercial Construction and Home Improvement With 150% Upside
Voss Capital is a Houston hedge fund founded by Travis Cocke in 2011, running value-oriented, bottom-up strategies focused on underfollowed small- and mid-cap special situations through long/short and long-only funds, increasingly turning activist.
In plain words
This analysis is about Griffon Corp. (GFF), a company that looks like a typical construction firm but has a hidden gem: it's North America's largest garage door maker (Home and Building Products, or HBP). Unlike many housing stocks, HBP gets most of its revenue from replacing old doors and commercial buildings, not new homes, making it less risky. The author argues the market undervalues HBP, and if it were spun off or sold, the stock could rise 150%. For regular investors, this means looking for companies with overlooked valuable assets, especially when they're pushing for change like board reforms or asset sales. It's worth reading because it uses concrete data—like garage door replacement being the top home improvement for return on investment—to show why this seemingly boring business is actually a cash machine.
Voss Capital's research report focuses on Griffon Corp. (GFF), noting that it is not a pure-play on residential housing stocks but rather an investment through a combination of building products and home improvement businesses.

Theme & Background
This chapter focuses on Voss Capital's in-depth analysis of Griffon Corp. (GFF) , aiming to clarify that the fund's portfolio is not a pure bet on homebuilding stocks but includes a diversified basket of building products and home improvement businesses. The report argues that GFF is an inefficient mini-conglomerate with a hidden high-quality asset—the Home and Building Products (HBP) business, the largest garage door manufacturer in North America. Recently, a proxy fight has driven board reforms, paving the way for value realization.
Core Thesis
The report's core investment thesis is: GFF's HBP business is a hidden high-quality asset and a prime acquisition target whose value is underestimated by the market, and it is expected to unlock value for shareholders through standalone operation or a sale. Contrarian judgments include:
- Although the market views GFF as a homebuilding stock, its revenue mix (48% residential repair & remodel, 41% commercial, 11% new residential construction) makes it less dependent on the new residential construction market and less volatile.
- Garage door replacement was the highest-ROI home improvement project in 2022 (ranked first three times in four consecutive years), with opaque pricing and low consumer sensitivity to price increases, giving HBP pricing power.
Key Arguments & Data
The report supports its thesis with the following data and logic:
1. Business Structure & Valuation:
- GFF's current stock price is $23, market cap $1.2 billion, and enterprise value $2.7 billion (including $1.5 billion net debt, net of cash from the defense electronics sale).
- The defense electronics business was sold for $330 million, with after-tax cash of $300 million ($5.62 per share).
- The consumer business is expected to generate FY2023 revenue of $1.5 billion and EBITDA of $170 million (12% margin), valued at $1.2–1.5 billion.
2. HBP Business Advantages:
- Revenue mix: 48% residential repair & remodel, 41% commercial, 11% new residential construction. The commercial segment covers diverse applications such as warehouses, retail, and government buildings.
- The residential repair & remodel market is far less volatile than new home construction, and garage door replacements carry high prices and high margins (average $4,000).
- Garage door prices have risen 60%–100% in recent years, but due to consumers' low purchase frequency and lack of price benchmarks, acceptance of price increases is high.
3. Market Drivers:
- Home improvement spending has a low correlation with interest rates (14-month lag, R²=0.15) but a strong correlation with home price appreciation (no lag, R²=0.52).
- As of end-2021, U.S. home prices and home equity had risen 27% and 35%, respectively, since 2019, supporting continued home improvement spending.
- Google search trends for "garage door replacement" are near historical highs, serving as a positive forward indicator for HBP.

Companies/Assets Involved
- Griffon Corp. (GFF) : Core subject of analysis, with the author bullish. GFF is a mini-conglomerate with the hidden HBP asset. Recent proxy fight drove board reforms (90% of non-insider shareholder votes in favor, addition of independent directors, declassification of the board).
- Home and Building Products (HBP) : GFF's hidden high-quality asset, North America's largest garage door manufacturer, with brands including Clopay (residential) and CornellCookson (commercial). The report believes it is a prime acquisition target, operating independently and undervalued.
- Consumer Business : Another GFF business line, including long-handled tool brands and the Hunter ceiling fan business, valued at $1.2–1.5 billion, but not the focus of this chapter.
- Defense Electronics Business : Agreed to be sold for $330 million, with expected after-tax cash of $300 million. The report believes the sale will unlock value.
Investment Implications
Specific directions for investors:
- Focus on GFF's value realization path: The report argues that the HBP business is a prime acquisition target, and its standalone operation and potential sale could trigger a stock re-rating. Investors should track the use of cash after the defense electronics sale closes (e.g., debt repayment or buybacks).
- Favor the home improvement sector: Based on the high ROI of garage door replacement, low interest rate sensitivity, and home price appreciation drivers, the report believes the HBP business has defensive qualities and growth potential, and recommends investors focus on the valuation recovery opportunity in GFF's HBP business.
- Beware of market misconceptions: The author emphasizes that GFF is not a pure homebuilding stock; its revenue mix (48% repair & remodel, 41% commercial) reduces cyclical risk. Investors should avoid lumping it together with highly volatile homebuilding stocks.
Theme and Background
This chapter focuses on the Commercial segment within Home and Building Products (HBP) of Griffon Corp. (GFF). The report points out that this segment is not reliant on the residential new construction market, but is instead driven by commercial building activity, and is currently in a strong growth cycle. While the market broadly fears a slowdown in the residential market, the author believes that the independence and leading position of the Commercial business make it an undervalued core asset.
Core Thesis
The author's core argument is: HBP's Commercial business is the absolute leader in the North American rolling door market, its growth momentum is strong and sustainable, and it is a key component of GFF's hidden value. The counterintuitive judgment lies in the fact that although the market focuses on the residential construction cycle, the Commercial business never declined during the 2020 pandemic, and its current order backlog is at an all-time high, demonstrating that its growth is independent of residential market fluctuations.
Key Arguments and Data
1. Market Dominance: The CornellCookson brand holds approximately 40% share of the North American rolling door market and is described by competitors as the "undisputed leader."
2. Growth Acceleration: Commercial sales remained stable in 2020 and have since accelerated for six consecutive quarters, with the most recent quarter growing 66% year-over-year, with no signs of slowing. The company indicates that its order backlog is "significantly above historical levels."
3. Strong Leading Indicators: The Architectural Billings Index (ABI) is a 9- to 12-month leading indicator for commercial building activity. In March 2022, the ABI Billings score was 58 (vs. 51 in February), and the Design Contract score was 60.5 (vs. 55.2 in February), both above the 50 expansion threshold. The average backlog stands at 7.2 months, a record high since data tracking began in 2010.
4. Margin Improvement: Despite steel price increases and supply chain issues, HBP's margins have exceeded 20% (21% LTM), and the company guides that its margins in the second half of fiscal 2022 will be consistent with the first half (23%). Industry competitors view this as HBP's normalized margin level.
5. Strong Cash Flow: LTM EBITDA is $253 million, and after the company raised its guidance, fiscal 2022 (ending September) EBITDA is expected to be approximately $330 million. Capital expenditures are extremely low, averaging only $13 million per year since 2015.
Comparison Table: ABI Index and Backlog Changes
| Indicator | February 2022 | March 2022 | Change |
|---|---|---|---|
| Billings Score | 51 | 58 | +7 |
| Design Contract Score | 55.2 | 60.5 | +5.3 |
| Average Backlog (months) | ~6 months | 7.2 months | +1.2 months (YoY) |
Companies/Assets Involved
- Griffon Corp. (GFF): Parent company, currently with an enterprise value of $2.7 billion and a stock price of $23. The author believes its conglomerate structure leads to a valuation discount.
- HBP (Home and Building Products): Core asset, with the Commercial business led by the CornellCookson brand. If valued at 9-12x EV/EBITDA, HBP would be worth $3.0–4.0 billion (after taxes on a sale), already exceeding GFF's total enterprise value.
- Consumer Business: Another GFF segment, with revenue of $1.5 billion and EBITDA of $180 million; the author estimates its value at $1.2–1.5 billion.
Investment Implications
The author argues that if GFF's conglomerate discount is eliminated (e.g., through a spin-off or sale of HBP), the stock has 150% upside to $60. The specific direction for investors is: focus on GFF's asset divestiture or restructuring events, especially HBP's Commercial business as a high-quality asset that could be acquired by private equity at 10-12x EBITDA. The current market pricing does not fully reflect the standalone value and growth potential of this business, and investors should position themselves to exploit the valuation mismatch.
