---

#### 1. Key Findings

**Net Assessment: MIXED-POSITIVE for the thesis.**

- PPIH is a **project-based custom manufacturer** — not a recurring-revenue business. Revenue flows from discrete engineering contracts, creating inherent lumpiness. This is neither a SaaS nor a commodity business: it is an industrial engineer-to-order niche supplier. [S1]
- The business model is more defensible than it initially appears: products are custom-engineered to exact project specifications, cannot be easily substituted mid-project, and require regulatory/customer qualification to compete. This creates project-level switching costs that moderate the lumpiness risk. [S1][S3]
- The single most important structural fact is the **Middle East mix shift** — from a primarily North American specialty manufacturer to a global-facing company with ~46% of revenue now in MENA. This changed both the growth trajectory and the gross margin profile fundamentally. [S2]
- The **absence of a recurring revenue component** (no maintenance contracts, no SaaS, no recurring services agreements) means the business requires constant new project wins to sustain revenue. Backlog is the single most important leading indicator and must be monitored every quarter. [S1]

---

#### 2. Implications for Thesis and Valuation

- Because revenue is project-based, historical CAGR is a **poor predictor** of future revenue without understanding backlog trajectory. A $121.6M backlog at Jan 31, 2026 [S2] translates to approximately 7 months of revenue coverage at the FY2026 run rate — that visibility is good but not exceptional.
- The gross margin expansion from 13% to 33% is **structural, not cyclical**, driven by geographic mix shift (higher-margin Middle East work) and operating leverage. Whether this is durable depends on whether Saudi JV projects remain high-margin as the JV matures and competition enters.
- Valuation should anchor on **normalized operating income** (EBIT), not EPS, due to the DTA distortions and NCI complexities in reported earnings. EV/EBIT is the cleanest lens; a DCF using NOPAT (net operating profit after tax) is the most rigorous approach.
- There is **no identifiable recurring revenue floor** that limits downside. If the backlog empties without replacement, revenue can fall sharply (as it did in FY2021, -34% peak-to-trough).

Explain how PPIH makes money, map the value chain, identify unit economics, and establish which metrics are decision-relevant vs. irrelevant for this specific business.

---

#### 4. Narrative Analysis

##### How PPIH Makes Money

PPIH receives a contract (typically from a general contractor, EPC firm, utility, or oil company) to supply custom-engineered specialty piping for a specific construction or infrastructure project [S1]. The sequence:

1. **Engineering:** PPIH's engineers design a piping system to the client's thermal, pressure, and environmental specifications (temperature range, insulation thickness, jacket material, leak detection requirements).
2. **Fabrication:** Raw steel pipe is jacketed with insulation (polyurethane foam or equivalent) and an outer protective layer (HDPE, fiberglass, or galvanized steel) at one of PPIH's manufacturing plants. Custom fittings, elbows, T-sections, and couplings are also fabricated. Products are custom-cut to job-site dimensions — no off-the-shelf inventory.
3. **Delivery:** Pre-fabricated pipe sections are shipped to the job site, where a contractor installs them. PPIH typically does not perform installation itself (except in some international markets where it offers turnkey services).
4. **Revenue Recognition:** Most contracts use the **percentage-of-completion (over-time) method** under ASC 606 — revenue is recognized as fabrication progresses based on cost incurred as a percentage of total estimated costs. Shorter, simpler projects may recognize revenue upon delivery/acceptance. [S1]

This means the revenue meter runs while the factory is active on a contract. A large project generates several months of revenue recognition spread over its fabrication period.

##### Products and Market Segments

PPIH organizes its products around five broad categories [S1]:

| Product Category | End Market | Key Application | Typical Customer |
|-----------------|-----------|-----------------|-----------------|
| District heating & cooling pipe | District energy | Underground energy distribution | Universities, municipalities, hospitals, military, developers |
| Oil & gas insulated pipe | Upstream/midstream oil & gas | Flow lines, gathering, transmission | Aramco, oil sands operators, NOCs |
| Chemical/containment pipe | Industrial | Secondary containment, hazardous fluid transport | Chemical plants, refineries |
| Anti-corrosion coating | Oil & gas infrastructure | Corrosion protection on steel pipe | Pipeline operators |
| Leak detection systems (PermAlert) | All segments | Fluid intrusion monitoring in jacketed systems | Utilities, environmental compliance customers |

**Temperature range differentiation:** PPIH's product range spans cryogenic (-320°F/HI-GARD) to ultra-high-temperature (1,200°F/MULTI-THERM). Most competitors are narrow-range; PPIH's breadth enables single-source supplier status on complex projects. [S3]

##### Value Chain

```
Raw Materials          → PPIH Internal          → Customer / EPC
─────────────────────    ──────────────────────    ──────────────
Steel pipe (commodity)   Engineering design       General contractors
PU foam insulation       Custom fabrication        Utilities
HDPE jacket resin        QC/testing               Oil companies
Fittings/hardware        Packaging/logistics       Government agencies
                         (No installation in NA)   (Some EPC in MENA)
```

**Supplier power:** Steel is PPIH's primary raw material and is highly cyclical. PPIH cannot control input costs. However, most contracts are priced with a materials passthrough or fixed price based on current steel costs at time of bid — the risk is in bidding delays (rising steel between bid and award) and in fixed-price contracts where steel surges after award. [S1]

**Customer power:** Major customers (Aramco, large utilities, EPC firms) have substantial buying power. However, once a project is specified around PPIH products and PPIH holds the approved vendor qualification, substituting a competitor mid-project is expensive and time-consuming. **Customer switching costs exist at the project level, not the relationship level.** [S3]

##### Unit Economics

For an engineer-to-order manufacturer, the relevant unit economics are per-project, not per-unit:

| Economic Driver | Description | FY2026 Benchmark |
|----------------|-------------|-----------------|
| **Revenue per project** | Highly variable ($100K to $20M+); not directly disclosed | N/A (not reported) |
| **Gross margin per project** | Mix of materials + labor + overhead vs. contract price | 32.9% (FY2026 consolidated) [S4] |
| **Backlog-to-revenue conversion** | How quickly backlog converts to recognized revenue | ~7 months at FY2026 run rate |
| **Fabrication capacity utilization** | % of plant capacity in use | Not disclosed; implied high in FY2026 given capex surge |
| **G&A as % of revenue** | Fixed overhead scale test | 16.7% (FY2026); down from 19.4% (FY2022) — positive operating leverage [S4] |
| **Selling expense as % of revenue** | Largely variable (commissions, rep fees) | 2.2% (FY2026) — stable [S4] |

##### Revenue Type: Transactional and Project-Based (Not Recurring)

| Revenue Type | Characteristics | PPIH Proportion (est.) |
|-------------|----------------|----------------------|
| Project-based contracts (over-time) | 6–24 month delivery windows; lumpy | ~85-90% (judgment) |
| Product/component sales (point-in-time) | Shorter; fittings, couplings, PermAlert units | ~10-15% (judgment) |
| Maintenance/service | Not a meaningful revenue stream | ~0% |
| Recurring SaaS/subscription | Not applicable | N/A |

**Critically:** There is **no recurring revenue floor**. Revenue depends entirely on winning and executing new contracts. This is standard for project manufacturers but means the business has higher cyclical exposure than appears from current momentum.

##### Geographic Operating Model

PPIH manufactures in 8+ facilities across North America and the Middle East [S1]:

| Region | Facilities | Revenue Share (Est.) |
|--------|-----------|---------------------|
| US | Rolling Meadows IL; New Iberia LA; Lebanon TN; Ohio (new, FY2026) | ~33% |
| Canada | Camrose AB; Vars ON | ~20% |
| Middle East / MENA | Dammam & Riyadh (Saudi JV); Abu Dhabi (UAE); Fujairah (UAE) | ~46% |
| Other (Egypt, India) | Beni Suef (Egypt); Gandhidham (India) | <5% |

The Saudi JV (Perma-Pipe Saudi Arabia LLC + Perma-Pipe Gulf Arabia LLC) is jointly owned with Zamil Industrial Investment Co. and is the primary growth driver of the past three fiscal years. [S2]

##### Which Metrics Are Relevant vs. N/A

| Metric | Relevant for PPIH? | Notes |
|--------|------------------|-------|
| Backlog ($M) | **YES — most important** | Only forward-looking indicator; check every quarter |
| Revenue ($M) | YES | Top-line; evaluate YoY + TTM context |
| Gross Margin (%) | YES | Mix-sensitive; watch MENA vs. NA margin differential |
| Operating Margin (%) | YES | Best normalized profitability measure |
| G&A / Revenue (%) | YES | Operating leverage test |
| EPS | CAUTION | Tax distortions (DTA) and NCI make EPS noisy; use Adj EPS |
| ARR / NRR / Churn | N/A | No subscription revenue |
| TPV / GMV | N/A | Not a payments or platform company |
| Same-store sales | N/A | No stores |
| LTV / CAC | N/A | Project business; no meaningful LTV/CAC unit |
| Free Cash Flow | YES — with care | FCF is lumpy due to working capital swings; use 3-year avg |

##### Simplified PPIH Revenue Build (FY2026 Estimate)

| Geography | Revenue ($M est.) | % Total | Growth Driver |
|-----------|-----------------|---------|--------------|
| Middle East / MENA / India | ~$97 | ~46% | Saudi JV, Aramco, UAE district cooling |
| United States | ~$70 | ~33% | District energy, oil/gas, data centers |

*MENA figure estimated from 226% growth cited in press releases and approximate prior-year mix.*

##### Operating Leverage Track Record

| FY | Revenue | G&A ($M) | G&A % Rev | Op Income ($M) | Op Margin |
|----|---------|----------|-----------|----------------|-----------|
| FY2021 | $84.7 | $17.2 | 20.3% | ($11.4) | NM |
| FY2022 | $138.6 | $19.9 | 14.4% | $8.1 | 5.9% |

| FY2026 | $210.9 | $35.3 | 16.7% | $29.4 | 14.0% |

*G&A % has been declining on a longer-term basis while operating margin has nearly tripled — clear positive operating leverage. [S4]*

---

#### 8. Open Questions and Data Gaps

1. **Saudi JV ownership split and profit allocation** — The NCI line in FY2024+ tells us Zamil Industrial holds a minority interest, but the exact percentage and priority waterfall are unknown. This affects PPIH's effective economics from the JV. **Step 06.**
2. **Contract duration and revenue recognition cadence** — What percentage of revenue is recognized over-time vs. point-in-time? This affects FCF-to-earnings quality. **Step 04.**
3. **PermAlert leak detection revenue** — Is this a growing standalone product or just a bundle with piping contracts? Not separately disclosed. **Step 03.**
4. **Ohio facility product focus** — The press releases mention AI data center chilled water distribution. What specific products? What is the revenue ramp expectation? **Step 07.**

## Financial Snapshot

### Step 04 — Financial Statement Quality and Adjustments
### Perma-Pipe International Holdings, Inc. (PPIH)
**Date:** 2026-05-12

---

#### 1. Key Findings

**Net Assessment: MIXED — Earnings quality is improving but carries three persistent concerns.**

1. **Material weakness in internal controls** persisted through at least FY2024 (disclosed in consecutive 10-Ks for FY2023 and FY2024). A 10-K/A was filed for FY2024. Whether this was remediated in FY2025/FY2026 is the most important unresolved quality concern. [S1]
2. **Tax distortions are material:** FY2024 GAAP EPS of $1.30 includes a ~$3.3M deferred tax asset recognition that is non-recurring; FY2024 "true" EPS excluding this was closer to ~$0.87. Conversely, FY2025 had a $2.1M CEO departure charge and elevated tax rate that suppressed reported EPS. Normalized EPS must be used for any year-over-year comparison. [S2][S3]
3. **Non-controlling interest (NCI) from Saudi JV reduces the equity investor's share of earnings.** PPIH consolidated 100% of Saudi JV revenue and costs, then backs out the NCI's share. The NCI grew from $2.74M (FY2024) to an estimated $3.57M (FY2025) — this dilutes effective EPS to common shareholders and will grow as the JV scales. [S2]
4. **Positive:** No short seller reports, no SEC investigations, no material class-action lawsuits, and no significant fraud allegations were found. PPIH is clean on adversarial research. [S4]
5. **Positive:** GAAP EPS of $2.09 in FY2026 is now credibly "real" — the large DTA distortion that inflated FY2024 has washed out, and the company is generating genuine cash earnings. Normalized EBIT margin of ~14% is sustainable and not a management-adjusted construct. [S2]

---

#### 2. Implications for Thesis and Valuation

- Use **EV/EBITDA** as the primary valuation multiple, not P/E — EBITDA is less susceptible to the tax/NCI distortions that make EPS noisy at PPIH.
- **Normalized EBITDA (FY2026): ~$36-37M** (adding back ~$2M one-time SOX/CEO costs to $34.4M reported EBITDA). [S2][S3]
- The persistent material weakness is a governance red flag that depresses an appropriate valuation multiple until remediated. A clean internal controls opinion would be worth ~0.5–1.0x EBITDA in multiple expansion.
- NCI will continue growing as Saudi JV scales; investors should underwrite PPIH's 60% (estimated) economic ownership of the JV's profits, not 100%.

---

#### 3. Objective

Convert reported GAAP financials to analytically usable normalized earnings. Identify one-time items, test "recurring" adjustments, analyze SBC/D&A/lease treatment, and complete the adversarial research sweep.

---

#### 4. Narrative Analysis

##### GAAP to Normalized Earnings Bridge

PPIH does not report an official non-GAAP adjusted earnings metric routinely. However, several material items distort reported GAAP results:

**FY2024 (year ended Jan 31, 2024) — key distortion: DTA recognition**
- Tax benefit of **($3.3M)** from partial release of US valuation allowance on deferred tax assets
- This resulted in a reported net income of $13.2M (consolidated) vs. a pre-tax income of only $9.9M
- Net income attributable to common shareholders was $10.5M — on $9.9M pre-tax income — only possible because of the tax benefit
- **Adjusted FY2024 EPS (normalizing to ~25% effective tax rate): ~$0.87/share** vs. reported $1.30/share

**FY2025 Q2 (Jul 31, 2024) — key distortion: CEO departure charge**
- One-time executive compensation charge of **~$2.1M** (CEO Mansfield departure/transition costs)
- Q2 FY2025 adjusted income before tax would have been $4.9M vs. reported $2.8M [S3]
- Adjusted Q2 FY2025 EPS ≈ $0.34/share vs. reported $0.10/share

**FY2026 Q4 (Jan 31, 2026) — one-time items**
- **CEO departure costs:** ~$2.0M
- **SOX 404 compliance costs** (accelerated filer transition): ~$1.0M
- Q4 effective tax rate was 12.3% (unusually low; benefit from geographic tax structure)
- Adjusted FY2026 EBITDA: ~$36–37M vs. reported $34.4M [S2]

##### Normalized EPS and EBITDA Summary

| Metric | FY2024 | FY2025 | FY2026 |
|--------|--------|--------|--------|
| Reported EPS (diluted) | $1.30 | $1.12 | $2.09 |
| Reported Net Income (Common, $M) | $10.5 | $9.0 | $17.0 |
| DTA benefit (non-recurring, $M) | $3.3 | — | — |
| CEO departure/transition costs ($M) | — | $2.1 | $2.0 |
| SOX compliance costs ($M) | — | — | $1.0 |
| Tax rate distortion (est.) | ~25% norm. | Normal (~28%) | ~25% norm. |
| **Adj. Net Income (est., $M)** | **~$7.1** | **~$11.5** | **~$18.5** |
| **Adj. EPS (est.)** | **~$0.87** | **~$1.41** | **~$2.27** |
| Reported EBITDA ($M) | $17.2 | $23.9 | $34.4 |
| **Normalized EBITDA (est., $M)** | **~$17.2** | **~$26.0** | **~$36–37** |

*Adj. Net Income = Pre-tax income × (1 - normalized ETR ~25%) – NCI. Normalized EBITDA adds back one-time operating charges.*

##### Material Weakness in Internal Controls

This is the most concerning quality flag in PPIH's financial statements:

- **FY2022:** Clean audit opinion; no material weakness disclosed [S5]
- **FY2023:** Material weakness disclosed — inventory cycle count procedures at one US facility failed to catch discrepancies [S1]
- **FY2024:** Disclosure controls and procedures deemed NOT EFFECTIVE — same underlying issue persisted. A **10-K/A (amended filing)** was required, suggesting either a restatement or a material disclosure update [S1]
- **FY2025 and FY2026:** Material weakness status is UNKNOWN from the data available (full 10-K text not read). The press release for FY2026 did not mention a material weakness, which is a weak positive signal. If the material weakness persisted into FY2026, it would be a significant concern at the current valuation.

**What the material weakness means practically:**
- The inventory count deficiency could result in understated or overstated cost of goods sold in any given period — directly affecting gross margin accuracy
- Over-time revenue recognition relies on accurate cost-to-complete estimates; if cost tracking is unreliable, revenue and margin figures are less trustworthy
- It is a governance and operational excellence flag that sophisticated buyers in the strategic alternatives process will scrutinize

##### Non-Controlling Interest Economics

The Saudi JV consolidation creates an important distinction:

| Item | FY2024 | FY2025 | FY2026 |
|------|--------|--------|--------|
| Consolidated Net Income ($M) | $13.2 | $13.1 | $20.6 |
| Less: NCI (Saudi JV minority) ($M) | $2.7 | $3.6* | — |
| Net Income to Common ($M) | $10.5 | $9.0** | $17.0 |

*Estimated. **FY2025 net income to common decreased YoY due to (1) absence of FY2024 DTA benefit and (2) larger NCI share.*

The NCI represents the Zamil Industrial minority stake in the Saudi JV. As the JV generates more profit, the NCI deducted from common shareholder earnings grows. This creates a drag: if the JV is responsible for, say, 50% of consolidated operating income, and Zamil Industrial holds 40% of the JV, then effectively ~20% of PPIH's operating income is attributable to a third party. The exact JV ownership split has not been confirmed from available data.

##### Stock-Based Compensation Analysis

| Year | SBC ($M) | % of Revenue | Notes |
|------|----------|-------------|-------|
| FY2022 | $1.1 | 0.8% | Normal director/exec grants |
| FY2023 | $1.0 | 0.7% | Stable |
| FY2024 | $0.9 | 0.6% | Slight decline |
| FY2025 | $0.9 | 0.5% | Near-record low % |
| FY2026 | $2.5 | 1.2% | Step-up: new CEO Sagr RSU grant (29,259 shares); new board members' initial equity grants |

SBC at 0.5–0.8% of revenue is very low for a public company — well below the typical 2–5% for tech and even below 1–2% for industrials. This is a genuine shareholder-friendly governance feature, though it also reflects that management and board are not compensated extravagantly. The FY2026 step-up to $2.5M reflects new leadership grants and should normalize downward in FY2027.

##### Lease and Capital Obligations

PPIH uses several manufacturing and office facilities under long-term operating leases (the Tennessee facility was sold and leased back in FY2022, generating $9.1M in proceeds). Total operating lease obligations as of Jan 31, 2024: $15.7M, with annual payments of ~$1.9M. These are not material enough to significantly affect the leverage calculation but should be included in enterprise value.

Finance lease obligations are minimal ($0.1M as of Jan 31, 2024).

The **Tennessee sale-leaseback** created a long-term finance obligation of $9.2M that PPIH is slowly paying down; the sale-leaseback proceeds were recognized as a financing rather than a one-time gain due to the structure.

##### Goodwill and Intangibles

Goodwill of ~$2.2M is trivially small (1.0% of total assets) and has been essentially flat for years — no material impairment risk. No other significant intangible assets are on the balance sheet. This business does not carry valuation risk from intangible write-downs.

---

#### 5. Adversarial Research Sweep

**METHODOLOGY:** Conducted searches for: "PPIH short seller report," "Perma-Pipe fraud," "PPIH class action lawsuit," "Perma-Pipe accounting fraud," "Perma-Pipe SEC investigation," and cross-referenced against known short seller publishers (Muddy Waters, Hindenburg, Citron, Spruce Point, Kerrisdale, Blue Orca, Scorpion, Iceberg, Wolfpack, Viceroy, Gotham, Fuzzy Panda, Culper, etc.).

**FINDINGS:**

**1. No Short Seller Reports Found**
No short seller research reports targeting PPIH were identified from any major short seller publication. This is expected for a small-cap industrial company with limited institutional following and no high-multiple valuation that typically attracts shorts.

**2. SC 13D/A Filing (August 2024) — Activist Investor**
A Schedule 13D/A was filed in August 2024, indicating a significant (>5%) shareholder disclosed amended ownership with activist intent. This led to the 2025 board refresh (3 directors received ~33% votes against at the June 2025 AGM and resigned). This is **governance activism, not fraud**. The outcome (board refresh, strategic alternatives process) was constructive. [S6]

**3. Material Weakness — Internal Controls**
The FY2023 and FY2024 material weaknesses are disclosed in the SEC filings and are legitimate governance concerns, not fraud. The inventory cycle count procedure failure could theoretically allow small misstatements of COGS, but there is no evidence of intentional manipulation and the amounts are not material to the overall financial picture.

**4. Long-Aged Middle East Receivable**
One customer balance of $2.2M has been outstanding since 2013. As of Jan 31, 2024, it was not reserved. This is a credit risk disclosure, not fraud. [S1]

**5. "Loan Payable to GIG" ($2.753M)**
The 10-K contractual obligations table includes a "Loan payable to GIG" of $2.753M. GIG has not been identified definitively in the available data — this could be Gulf Insurance Group (a Kuwaiti insurance company) or another entity. This is a related-party item worth understanding but does not suggest impropriety based on available information. **Flag for Step 06 (Balance Sheet).**

**6. MFRI Inc. Legacy**
PPIH was formerly MFRI, Inc. (renamed March 2017). MFRI had reported losses in prior years and underwent a strategic restructuring. A review of publicly available information for the MFRI-era entity did not surface fraud allegations or SEC investigations.

**FINAL VERIFICATION SEARCH RESULT:** "Are there any short seller reports, regulatory investigations, class action lawsuits, whistleblower complaints, or significant controversies about Perma-Pipe International Holdings (PPIH) that have not been covered above?" — No additional material was found.

**CONCLUSION:** No short seller reports, fraud allegations, or material controversies were found targeting Perma-Pipe International Holdings, Inc. as of May 2026. This is a positive finding. The governance activism of 2024–2025 is the closest thing to controversy, and it produced a constructive board refresh with a strategic alternatives process. [S4][S6]

#### 8. Open Questions and Data Gaps

1. **Material weakness remediation status in FY2025 and FY2026** — The most important unanswered question for earnings quality confidence. Needs full 10-K text review. **HIGH priority.**
2. **Saudi JV exact ownership percentage** — Needed to properly calculate PPIH's share of JV economics. NCI proportion implies ~21% NCI share of JV consolidation; exact ownership percentage not confirmed.
3. **"Loan payable to GIG" identity** — Who is GIG and what are the terms of the $2.753M loan? Related-party disclosure needed. **Step 06.**
4. **Revenue recognition policy details** — What % of revenue is over-time vs. point-in-time? Are there any contracts with variable consideration or significant margin estimates that could be revised? **Need FY2025 10-K notes.**
