### Step 01 — Business Model & Overview: TopBuild Corp (BLD)

---

#### 1. Executive Summary

TopBuild Corp is the largest installer and specialty distributor of insulation products in the United States, operating at the critical intersection of building products manufacturing and construction services [S1]. The company was spun off from Masco Corporation in June 2015 and has grown through a combination of organic branch expansion and systematic M&A, scaling from ~$1.9B revenue at spin to $5.4B by FY2025 [S2]. In 2025, two transformative acquisitions — Specialty Products and Insulation (SPI) for $1.0B and Progressive Roofing for $810M — repositioned BLD beyond residential insulation into commercial/industrial mechanical insulation and commercial roofing services [S3].

---

#### 2. Business Model

##### Value Proposition
TopBuild provides two complementary services to the construction industry:

1. **Installation Services:** A builder or contractor hires BLD to physically install insulation (and ancillary building products) at a construction site. BLD employs the labor, sources the material (often from its own distribution network), and guarantees the installation.

2. **Specialty Distribution:** A contractor or installer purchases insulation products from BLD's distribution centers. BLD acts as a specialty wholesale distributor — buying from manufacturers (Owens Corning, Johns Manville, Knauf) and reselling with value-added logistics, stocking, and technical support.

##### Dual-Segment Model — Value Chain Position

```
Manufacturers (OC, JM, Knauf)
        ↓
[BLD Specialty Distribution] ← supplies product
        ↓
[BLD Installation Services]  ← performs labor
        ↓
Homebuilders / Commercial Contractors (DR Horton, Lennar, PulteGroup, Turner)
        ↓
End Customer (Homeowner / Building Occupant)
```

This dual-channel model is BLD's structural differentiator vs. IBP (install-only). The distribution segment:
- Creates purchasing scale that lowers material costs for installation
- Generates standalone margin on third-party installer sales
- Provides geographic coverage in markets where installation density is insufficient

##### Revenue Model
- **Installation:** Labor + materials revenue; pricing is typically per-square-foot or per-unit based on housing type
- **Distribution:** Product markup (distribution spread) on insulation and building products sold to third parties

#### 4. Business History & Key Milestones

| Year | Event |
|------|-------|
| 2015 | Spun off from Masco Corporation; ~$1.9B revenue; ~$1B goodwill |
| 2017–2020 | Steady organic growth + small bolt-ons; revenue $2.3B–$3.0B |
| 2021 | Distribution International (DI) acquired for $1.0B — doubles distribution scale |
| 2021–2022 | Revenue surges to $5.0B on housing boom + material price inflation |
| 2023–2024 | Organic growth moderates; EBITDA margins peak 19.3–19.5%; buybacks accelerate |
| 2025 | SPI ($1.0B) + Progressive Roofing ($810M); 7 total acquisitions; mix shifts to commercial |

---

#### 5. Customer Concentration & Relationships

- **Top customers:** National homebuilders — D.R. Horton, Lennar, PulteGroup, NVR, Meritage
- No single customer exceeds 10% of revenue (diversified builder base)
- Relationships are multi-year service agreements; switching costs exist (logistics integration, job-site consistency)
- Commercial: General contractors, mechanical contractors; more transactional but growing stickiness via SPI

---

#### 6. Competitive Positioning

| Dimension | TopBuild (BLD) | IBP (Installed Building Products) |
|-----------|--------------|----------------------------------|
| Revenue | $5.4B | ~$2.2B |
| Model | Install + Distribute | Install only |
| Branches | ~440 total | ~240 |
| End Market | Diversified (post-SPI) | ~80% residential |
| Margin | EBITDA 17–19% | EBITDA ~14–16% |
| Geographic | National | National (some gaps) |

BLD's advantages: scale-driven purchasing power, dual-channel synergies, acquisition platform in a fragmented $20B+ market.

---

#### 7. Capital-Light Services Model

CapEx as a % of revenue: ~1.1–1.4% (FY2021–FY2025) [S5]. This is classic services/distribution economics:
- No manufacturing plants; no heavy equipment factories
- Main fixed assets: vehicles, branches (often leased), distribution center equipment
- High FCF conversion: FCF margin ~12.9–15.1% of revenue (FY2023–2025)

### Step 04 — Financial Snapshot & Quality: TopBuild Corp. (BLD)

#### Key Findings
**Net positive — high financial quality with elevated goodwill risk.** BLD's financial reporting is clean and straightforward: GAAP earnings are of high quality (strong accrual-to-cash conversion, low non-recurring items), no restatements, and no material accounting concerns. The primary financial quality issue is the $3.05B goodwill balance (46% of total assets) accumulated through acquisitions — while not an immediate impairment risk, it creates vulnerability in a severe construction downcycle. The adversarial sweep found no significant short seller reports, class action suits, or fraud allegations.

#### Implications for Thesis and Valuation
The clean financial profile supports a premium EV/EBITDA multiple vs. peers with lower-quality earnings. The goodwill concentration is a known risk that `/complete-coverage` should scenario-test (what happens to equity value if BLD takes a 20-30% goodwill impairment?). FCF conversion is exceptionally high — the capital-light model means GAAP net income is actually understated vs. cash reality (D&A >> capex by $100M+ annually).

#### Objective
Assess the quality of TopBuild's financial statements, identify any adjustments needed for analysis, and conduct the mandatory Adversarial Research Sweep.

#### Narrative Analysis

##### Income Statement Quality

**Revenue recognition:** BLD recognizes installation revenue as services are performed (percentage of completion for installation contracts). Distribution revenue is recognized on shipment/delivery. Both are standard for the industry and consistent with ASC 606 requirements [S1].

**EBITDA adjustments:** Management reports "Adjusted EBITDA" which excludes:
- SBC (~$16-17M/year)
- Acquisition-related costs (legal, integration, transaction fees — likely $30-50M in FY2025 given two major acquisitions)
- Amortization of acquired intangibles ($50-70M/year — included in D&A but management may separate)

For analytical purposes, the reported EBITDA of $961M (FY2025) is close to "adjusted" — the incremental adjustments are relatively modest [S2].

**Earnings quality signals:**
- FCF/Net Income = $697M / $522M = **134%** — excellent; D&A ($169M) well exceeds capex ($59M), boosting cash vs. GAAP earnings
- Working capital as % of revenue has been stable — no inventory buildup, no AR manipulation concerns
- SBC of $16-17M/year is modest (0.3% of revenue) — not materially diluting GAAP earnings

##### Balance Sheet Quality

**Goodwill Analysis:**
| FY | Goodwill | % of Total Assets | Notes |
|----|---------|-------------------|-------|
| 2021 | $1,950M | 45.8% | Post-ISI acquisition |
| 2022 | $1,967M | 42.7% | Modest organic additions |
| 2023 | $2,043M | 39.5% | Tuck-in bolt-ons |
| 2024 | $2,112M | 44.6% | Bolt-on acquisitions |
| 2025 | $3,045M | **46.1%** | SPI + Progressive Roofing addition |

The goodwill jump from $2.1B (2024) to $3.0B (2025) reflects the ~$1.8B in acquisition purchase prices applied to deals where net assets were far less than purchase price. This is standard for service/distribution acquisitions (no hard assets), but creates goodwill exposure.

**Impairment scenario:** If BLD were to take a 30% impairment on goodwill ($914M), this would reduce equity by ~$914M × (1 - tax rate, ~25%) = ~$686M in after-tax equity impact, but would NOT affect cash flow. The book value of equity would decline from $2,316M to ~$1,630M — but EBITDA and FCF would be unchanged. Rating agencies and lenders covenant on EBITDA, not book equity, so the operational impact would be minimal. However, it would be a significant GAAP earnings event.

**Intangibles:** $1.35B of intangibles (primarily customer relationships and trade names acquired via acquisitions) are amortizing over 5-15 year lives. This creates a recurring amortization charge that distorts GAAP net income vs. economic reality; add-back is standard in adjusted metrics.

**Debt structure:**
- Total debt: $3.15B (FY2025) — primarily senior notes + revolving credit facility
- Interest rate: Mix of fixed-rate senior notes (~4.5-6% range) and floating-rate revolver
- Post-SPI, approximately $1.5B in new senior notes were issued in September 2025

##### Cash Flow Quality
| FY | Net Income | Operating CF | FCF | FCF/NI |
|----|-----------|-------------|-----|--------|
| 2022 | $556M | $496M | $419M | 75% |
| 2023 | $614M | $849M | $785M | 128% |
| 2024 | $623M | $776M | $707M | 114% |
| 2025 | $522M | $756M | $697M | 134% |

FY2022 FCF/NI was lower due to working capital build; FY2023+ shows excellent conversion as working capital normalized. The structural driver of FCF > NI is D&A >> Capex: in FY2025, D&A was $169M vs. Capex of $59M — a $110M non-cash item boosting cash vs. GAAP [S3].

##### Adversarial Research Sweep
*Note: Transcript analysis was not performed. This sweep is based on SEC filings, press releases, and web searches for adversarial coverage.*

**Short seller reports:** No material short reports identified. Short interest at 5.48% of float as of May 2026 — elevated vs. normal but not unusual given the pending QXO acquisition arb setup [S4].

**Class action lawsuits:** No material securities class action suits identified. BLD has routine construction-related litigation (personal injury, property damage, contract disputes) disclosed in 10-K risk factors — standard for a company with 18,000+ employees performing physical work at construction sites.

**SEC investigations:** No SEC investigations identified.

**Accounting irregularities:** No restatements in the past 10 years. Auditor changes: None flagged.

**Key 10-K risk factors of analytical note:**
- Goodwill impairment risk explicitly disclosed
- Contractor license/safety regulation compliance
- Dependence on a few major insulation manufacturers
- Integration risks from acquisitions
- Housing market cyclicality

**Overall adversarial sweep conclusion:** CLEAN — No material financial quality concerns beyond the known goodwill concentration. The financial reporting is straightforward and high quality.

|------|--------|---------|
| Cash | $185M | 2.8% |
| Goodwill | $3,045M | 46.1% |
| Intangibles (ex-GW) | $1,352M | 20.5% |

| Shareholders' Equity | $2,316M | — |
| Net Debt | $2,966M | — |
| Net Debt/EBITDA | **3.1x** | — |

#### Open Questions and Data Gaps

1. Precise debt maturity schedule and covenant terms (revolving credit facility details)
2. Amortization of acquired intangibles vs. D&A breakdown (separation for "adjusted" metrics)
3. Working capital DSO/DPO trends by segment post-SPI
4. Tax rate guidance for 2026 (SPI integration may affect deferred tax position)

**Next-Step Dependencies:** Step 05 should track the quarterly momentum trend, particularly the margin impact of SPI and Progressive Roofing entering the income statement. Step 06 should provide full leverage analysis.
