Prepared for: Net Lease Deal Team | Subject: Sale-Leaseback Opportunity Assessment
Cornerstone Building Brands is the largest exterior building products manufacturer in North America — $5.3 billion in revenue, 18,800 employees, 93 manufacturing plants. CD&R took it private in July 2022 for $5.8 billion. Today it carries $4.8 billion in debt at Caa1/B-, every C-suite officer has turned over in 12 months, and creditors organized a coordination pact on February 20, 2026. The company has 40 owned manufacturing and distribution properties that have never been monetized. This report is the complete intelligence package for evaluating sale-leaseback opportunities before formal restructuring potentially closes the window.

Segments
| Segment | Revenue | Adj EBITDA | Margin | Products |
|---|---|---|---|---|
| Aperture Solutions | $2,510M | $297M | 11.9% | Vinyl windows, doors (Ply Gem, Simonton, Atrium) |
| Surface Solutions | $1,260M | $242M | 19.2% | Vinyl siding, stone veneer, trim (Mastic, Ply Gem) |
| Shelter Solutions | $1,540M | $179M | 11.6% | Metal buildings, roofing, wall panels (Metallic, MBCI, Robertson) |
Aperture is the largest segment by revenue. Surface has the highest margins. Shelter had the worst year — EBITDA margin halved from 19.4% to 11.6%, driven by volume declines and the botched ERP rollout.
Credit Profile
- Moody's: Caa1 (downgraded twice in 2025: B2 to B3 in March, B3 to Caa1 late 2025)
- S&P: B- (downgraded June 2025 from B)
- Interest expense: $450M/year on $16M operating cash flow = 1.3x coverage
- Creditors hired Moelis & Paul Weiss (Feb 2026) to coordinate ahead of restructuring talks
- Company retained PJT Partners as financial advisor
Budget Cycle
Calendar fiscal year. Annual operating plans typically set in December. But the normal budget cycle is irrelevant now — this is a restructuring timeline, not an operating timeline. Key decisions flow through CD&R (majority owner), PJT Partners (restructuring advisor), and the creditor bloc (Moelis/Paul Weiss).

2. Management Priorities
What They Said They Were Doing
The FY2024 10-K MD&A — the last official financial communication — laid out priorities that no longer match reality:
"We remain focused on enhancing long-term growth by taking actions to optimize our portfolio." — FY2024 10-K MD&A
"Our 2024 financial results were below management's expectations due to several factors, including lower than expected volumes, which have continued into fiscal 2025." — FY2024 10-K MD&A
"We have maintained price discipline across all segments and our work on cost-take-out initiatives has allowed us to partially offset the impact of lower volumes." — FY2024 10-K MD&A
Source: FY2024 10-K, filed March 17, 2025, SEC CIK 0000883902
What They Were Actually Doing
Phase 1 — Aggressive Growth (2023 to mid-2024): Rose Lee spent $957M on four acquisitions in 18 months — MAC Metal, EAS, Harvey ($461M), Mueller ($496M) — all funded by new debt. The strategy was to buy market share and consolidate exterior building products.
Phase 2 — Results Crater (Q3-Q4 2024): Shelter Solutions margin halved. $866M goodwill impairment — admitting they overpaid. Cash from operations collapsed 96% ($400M to $16M). The 10-K language shifts to "maintained price discipline" and "cost-take-out initiatives." Translation: growth failed, switching to defense.
Phase 3 — Leadership Exodus (Q1 2025): CEO Rose Lee resigned March 18, 2025 — the day after presenting a 32% EBITDA miss ($626M actual vs $918M pro forma target) to lenders on the Q4 2024 call. CAO Wayne Irmiter resigned the same day. No succession plan existed. Chairman John Krenicki stepped in as interim CEO.
Phase 4 — Restructuring Mode (Jul 2025 to present): Gunner Smith hired as permanent CEO from Owens Corning (Aug 2025). CFO Jeffrey Lee resigned Dec 29, 2025 — seven weeks before creditors organized. Interim CFO Christian Storch brought in from retirement. Creditors signed coordination pact Feb 20, 2026.
What They're NOT Saying
- Zero mention of sale-leaseback in any filing or press release
- Zero mention of real estate monetization
- Zero mention of footprint rationalization acceleration
- No restructuring language despite $935M in impairments and creditor coordination
- No public guidance for FY2025
3. Pain Points & Gaps
Financial Controls Are Broken
"We identified a material weakness... due to the implementation of a new ERP System... The presence of this material weakness creates a reasonable possibility that a material misstatement to the consolidated financial statements will not be prevented or detected on a timely basis." — FY2024 10-K
Source: FY2024 10-K, Item 9A
The Shelter Solutions ERP rollout in April 2024 failed IT general controls. Auditors issued an adverse ICFR opinion. Harvey and Mueller acquisitions — representing 8.6% of total assets and 7.6% of net sales — were excluded entirely from the internal controls assessment scope. Remediation is ongoing and not yet complete.
Meanwhile, the company has zero IT/ERP positions posted and zero finance/accounting positions posted, despite the CAO who signed the financials having resigned. Corporate capex was cut 43% ($12M to $7M). They are spending nothing on fixing the problem their auditors flagged.
Tariff Exposure — Unhedged
"The second Trump administration has proposed new, broad tariffs on all imports, as well as targeted tariffs on certain trading partners... could have a material adverse effect on our business, financial condition and results of operations." — FY2024 10-K, Risk Factors
Source: FY2024 10-K, Item 1A
Steel and aluminum tariffs hit all three segments directly. Canada represents approximately 7% of revenue. No hedging program is disclosed. Raw material inventories jumped 15% ($52M) year-over-year — they're either stockpiling ahead of tariffs or getting stuck with unsold product. Tariffs triggered the goodwill impairment assessment in 2024.
Covenant Pressure
Max secured leverage covenant: 7.75x. Actual leverage: approximately 8.2x. Min fixed charge coverage ratio: 1.0x, triggered if ABL availability drops. They disclosed covenant compliance as of December 31, 2024, and stated "sufficient liquidity for at least next 12 months." Creditors organized two months later.
Employee and Customer Complaints
Employee reviews (Indeed, 2024-2026, ≈1,937 reviews):
- "This company is poorly run. Hourly employees are low paid with little training. Poor work conditions. Constant layoffs when orders drop."
- "They preach safety, but it's selective. Production is king, regardless of lack of personal, poor equipment, or demeaning managers." — Lead Material Handler
- "The worst experience of my life, so I resign." — Feb 2026
- "If you have a family or out of work responsibilities, don't work here." — Production Assistant, Oct 2025
Source: Indeed reviews, Cornerstone Building Brands, 2024-2026
Customer complaints (X/Twitter, Reddit):
- "Where is your customer service? Warranty case for 4 windows, customer service non existent" — @RoryDonald, X, March 2026
- Recurring Reddit complaints on Ply Gem windows: seal failures within 4 years, leaking in new construction, cracking panes
- Mastic siding: warranty claims for fading, "cannot seem to get replacement parts"

Hiring Patterns — 306 Open Positions
What they're hiring tells you what's broken:
- 5+ Plant Managers simultaneously (Houston, Temple, Ballinger TX; Auburn WA) — plant leadership churn
- 2 Quality Managers (Lithia Springs GA, Houston TX) — quality system gaps
- ≈70% manufacturing/warehouse hourly — high turnover or volume-driven
- Heavy Texas concentration — Mueller integration still causing turnover
What they're NOT hiring tells you where investment has stopped:
- Zero finance/accounting roles — despite material weakness and CAO resignation
- Zero IT/ERP roles — despite material weakness caused by ERP failure
- Zero product development/engineering roles — no innovation investment
- Minimal corporate/HQ roles — Cary NC has 1 HR + 1 TA role posted

- $3.5 billion maturing in 25-29 months on a company generating $16M in operating cash flow
Source: FY2024 10-K, Note 11 — Long-Term Debt
What This Creates for a Net Lease Buyer
The restructuring negotiation is the #1 opening. SLB proceeds flowing into debt paydown benefits all stakeholders — creditors get principal reduction, CD&R preserves equity, the company gets operational flexibility. PJT Partners evaluates SLBs as a standard restructuring tool.
The leadership vacuum creates a decision-making opportunity. An interim CFO needs quick wins. A CEO eight months into the job hasn't locked into a strategy. New segment presidents are evaluating everything. Nobody has institutional loyalty to the status quo.
CD&R has done this before. They executed SLBs at Multi-Color Corporation (another portfolio company): 5 mission-critical manufacturing facilities, ≈900,000 SF, 20-year absolute NNN lease, 3% annual escalations, guaranteed by LABL, Inc. JLL marketed the portfolio. Cautionary note: Multi-Color filed Chapter 11 on January 29, 2026, restructuring $5.9B in debt down to $2.0B.

5. Competitive Landscape
Windows — Both Major Players Are Distressed
JELD-WEN (JELD) — direct comp, worse condition, already executing SLBs:
JELD-WEN CEO Bill Christensen, Q4 2025 earnings call (Feb 18, 2026):
"Expect to lose volume prioritizing pricing discipline. Share loss intentional and reflected in guidance."
"Experienced more disruption and service challenges earlier in the year... On-time-in-full performance [at Kissimmee FL plant] was approximately 55%."
Source: JELD-WEN Q4 2025 earnings transcript, Feb 18, 2026
JELD-WEN's numbers: $3.2B FY2025 revenue, 3.8% EBITDA margin, 8.6x leverage — worse than Cornerstone on every metric. They cut 2,300 employees (14% of workforce) in 2025. They completed a $38M sale-leaseback on their Coral Springs, FL facility in Q4 2025 and are publicly looking for more: "selective sale-leaseback opportunities" plus reviewing "other select parts of portfolio."
Market outlook from JELD-WEN: new single-family down low single digits, R&R down mid-single digits, no recovery expected in 2026.
The JELD-WEN Coral Springs SLB is the direct pricing comp for any Cornerstone deal. Same credit tier, same industry, same distress.
Siding — Structural Threat from Material Conversion
This is the most dangerous competitive dynamic in Cornerstone's portfolio.
James Hardie (JHX) CEO Aaron Erter, Q3 FY2026 earnings call (Feb 10, 2026):
"Substantial runway material conversion opportunity vinyl wood"
"80% of homes are not James Hardie — tremendous opportunity"
Source: JHX Q3 FY2026 earnings transcript, Feb 10, 2026
James Hardie's strategy is explicitly to convert homes from vinyl siding to fiber cement. North America Siding+Trim revenue: $2.675-2.85B (vs Cornerstone Surface Solutions $1.26B). EBITDA margin: 32.1% (vs Cornerstone 19.2%). They've already surpassed their FY2026 cost synergy target from the AZEK merger and are tracking toward $125M in annualized commercial synergies by FY2027, part of $250M total ($125M cost + $125M commercial). Exclusive homebuilder partnerships with Beazer and David Weekley.
Source: JHX Q3 FY2026 and Q2 FY2026 earnings transcripts
LP Building Solutions (LPX) CEO, Q4 2025 earnings call:
"LP SmartSide consistently gained share innovative products"
LP SmartSide siding revenue grew 8% for the full year — 4% price + 4% volume — in a market where housing starts were down 10%. Expert Finish (factory-finished siding) grew 35%, directly targeting vinyl's strongest markets in the Northeast and Midwest. EBITDA margin: 26%. New 70M sq ft Expert Finish line ramping in Green Bay, WI in Q2 2026.
Source: LPX Q4 2025 earnings transcript
For SLB pricing: Surface Solutions plants produce vinyl siding — a product under structural share loss from fiber cement and engineered wood. Long-term occupancy risk is real. Price siding plants at a wider cap rate than window or metal building plants.
Metal Buildings — Cyclical Down, Not Structural
Shelter Solutions revenue declined 7.5% despite the Mueller acquisition. EBITDA margin halved (19.4% to 11.6%). But this is cyclical non-residential construction weakness, not structural. Metal buildings serve warehouses, light industrial, agricultural, and retail applications. Infrastructure spending (IIJA, IRA) provides a tailwind. Nucor, which bought Cornerstone's Insulated Metal Panels business for $1B in 2021, is performing well — validating the category.
For SLB: Shelter Solutions plants — especially Mueller's Texas/Louisiana/Arizona facilities — are the safest for long-term lease durability.
Nobody Mentions Cornerstone
Zero public company competitors mention Cornerstone Building Brands, Ply Gem, Simonton, or any subsidiary brand by name on earnings calls. They compete at the value/builder-grade tier where nobody brags about beating them. The competitive threat is material substitution — vinyl to fiber cement, vinyl to engineered wood — not brand versus brand.

6. Wallet & Spend Signals
SG&A — Costs Rising Despite "Cost-Take-Out"
| Year | SG&A | % Revenue | Change |
|---|---|---|---|
| FY2023 | $955M | 17.7% | — |
| FY2024 | $1,015M | 19.2% | +6.3% |
Management claims "cost-take-out initiatives" while SG&A grew 6.3%. The increase is partially acquisition-driven (Harvey added $31M, Mueller added $20M to segment SG&A) but even normalizing, SG&A as a percentage of revenue expanded 150 basis points.
Surface Solutions is the only segment with actual cost discipline ($110M flat year-over-year).
Source: FY2024 10-K, segment financial data
Capex — Deferred Investment in the Worst Segment
| Segment | FY2024 Capex | YoY Change |
|---|---|---|
| Aperture | $90M | +57% (Harvey integration) |
| Surface | $56M | +12% |
| Shelter | $59M | -21% (Mueller acquired but capex cut) |
| Corporate | $7M | -43% |
No maintenance vs growth capex split disclosed. No forward capex guidance given. James Hardie guided $400M, LP guided $400M. Cornerstone gave nothing.
Source: FY2024 10-K, segment capital expenditure data
Zero Discretionary Investment
- Advertising: $18.2M on $5.3B revenue (0.34%). James Hardie spends aggressively on brand, contractor programs, and homebuilder partnerships. Cornerstone barely markets.
- R&D: Zero. No product development spending disclosed while James Hardie wins on ColorPlus and LP wins on Expert Finish.
- IT: Zero technology investment disclosed despite a material weakness caused by an ERP failure. Corporate capex cut 43%.
Operating Lease Commitments — Already Stretched
| Year | Annual Lease Payment |
|---|---|
| 2025 | $121M |
| 2026 | $115M |
| 2027 | $77M |
| 2028 | $63M |
| 2029 | $50M |
| Thereafter | $264M |
| Total | $690M |
PV of lease liabilities: $493M. Incremental borrowing rate: 9.23%.
Source: FY2024 10-K, Note 9 — Leases
An SLB adds to this $690M commitment. At $16M in operating cash flow, the company can barely service existing leases. New SLB rent only works if restructuring simultaneously reduces debt service.
Key Customer Concentration
One customer: 12.2% of net sales (≈$646M) across all segments. Unnamed but at that scale across windows, siding, and metal, almost certainly Home Depot or Lowe's. Loss of this customer would be catastrophic and would directly impact plant utilization at SLB facilities.

7. Conversation Ammunition
3 Data Points to Open With
1. "You have 40 owned manufacturing and distribution properties sitting on a balance sheet generating zero return on capital — while you're paying 9.3% weighted average on $4.8 billion in debt. Book value is $329 million. Fair market value is likely multiples of that."
Source: FY2024 10-K — 34 owned mfg + 6 owned distribution. Land $58.7M + buildings $270.8M gross.
2. "Your direct competitor JELD-WEN completed a $38 million sale-leaseback on their Coral Springs facility last quarter and told investors they're looking for more. Your sponsor CD&R did the same thing at Multi-Color — 5 properties, 20-year NNN, 3% annual escalations."
Source: JELD-WEN Q4 2025 earnings call (Feb 18, 2026); JLL marketing materials, Multi-Color SLB portfolio
3. "You generated $16 million in operating cash flow last year against $450 million in interest expense and $3.5 billion in debt maturing within 29 months. An SLB portfolio could generate $300-600 million in proceeds — enough to shift the restructuring math."
Source: FY2024 10-K cash flow statement and debt maturity schedule
The Quote That Connects to Pain
"Our 2024 financial results were below management's expectations due to several factors, including lower than expected volumes, which have continued into fiscal 2025." — FY2024 10-K MD&A
This was the last official financial statement before CEO Rose Lee resigned the next day (March 18, 2025), CFO Jeffrey Lee resigned nine months later (December 29, 2025), and creditors organized two months after that (February 20, 2026).
Use it: "Your own 10-K acknowledges volumes are declining into 2025. Your former CEO and former CFO both left within 12 months of that statement. You're sitting on 40 owned properties that could generate $400-600 million in immediate liquidity — without diluting CD&R's equity position and without the stigma of a filing. PJT Partners is already evaluating options. We should be one of them."
Competitor Weakness to Reference
JELD-WEN's CEO admitted to 55% on-time-in-full delivery at their Kissimmee facility and said share loss is "intentional and reflected in guidance." Their service problems are Cornerstone's customers' problem. That makes Cornerstone's manufacturing facilities mission-critical — the customers who depend on these plants can't afford another supplier failing them.
"Why Now" Narrative
Three things happened in the last 90 days:
First, the CFO resigned effective February 6. Christian Storch is interim — a 25-year finance veteran from Altra Industrial and Standex. He has fresh eyes on the balance sheet and a mandate to find liquidity solutions.
Second, creditors signed a coordination agreement on February 20 and hired Moelis and Paul Weiss. The company retained PJT Partners. SLB proceeds flowing into debt paydown is the one tool that benefits all stakeholders — creditors get principal reduction, CD&R preserves equity, the company gets operational flexibility.
Third, $3.5 billion in debt matures in 25-29 months. At Caa1, refinancing on reasonable terms is not available. Every $100 million in SLB proceeds at current EBITDA reduces leverage by approximately 0.17x. A $500 million portfolio gets leverage from 8.2x to 7.4x — back inside the 7.75x covenant.
The window is Q2 2026. Before formal proceedings add court oversight and complexity. CD&R already knows the playbook from Multi-Color.
The Gap Between Narrative and Reality
Management says "cost-take-out initiatives" while SG&A grew 6.3%. Management says "optimize our portfolio" while $957 million in acquisitions triggered $866 million in impairments within 12 months. The 10-K says "sufficient liquidity for 12 months" but creditors organized two months after it was filed. The one asset that is not being discussed publicly — 40 owned manufacturing facilities — is the one asset that could change the restructuring math. That is the conversation to have with PJT Partners.
8. Management Workup
Gunner Smith — CEO (since August 11, 2025)
Background: 17 years at Owens Corning, culminating as President of Roofing since 2018. Led OC's market-leading roofing business across US and Canada. Before Owens Corning: National Sales Manager at PlyGem — now part of Cornerstone — so he knows this company's legacy business. Before PlyGem: 8 years at Elk Corporation. Board member at Howmet Aerospace since 2023 (audit and finance committees). BS Business Administration, Mississippi State. Executive Program, U Chicago Booth.
Compensation: At Owens Corning (FY2024 proxy): $667,500 base, $794,813 bonus, $1,338,789 stock awards, ≈$2.9M total. At a private company with no stock comp, his Cornerstone package is likely heavily cash- and incentive-weighted. CD&R typically structures portfolio company CEO comp as base + cash bonus + equity rollover/co-invest.
Communication style: No public earnings calls at Cornerstone (private company). Only boilerplate press release language: "honored and excited to join... remarkable company with an exceptional portfolio of brands." No strategic vision articulated publicly.
Assessment: Sales DNA, not finance DNA. Will respond to revenue and customer framing, not balance sheet optimization. His PlyGem heritage means he has an emotional connection to the legacy business. But CD&R hired him as a turnaround operator — he knows the mandate. Only 8 months in, still in assessment mode. Key vulnerability: no permanent CFO to partner with.
Sources: Owens Corning FY2024 proxy (DEF 14A); Cornerstone press release Jul 21, 2025; Howmet Aerospace proxy
Christian Storch — Interim CFO (since February 6, 2026)
Background: Age 66. CFO of Altra Industrial Motion Corp for 14 years (Dec 2007 to Jan 2022). VP and CFO at Standex International (2001-2007). Before Standex: Divisional Financial Director and Corporate Controller at Vossloh AG (German transport tech). Audit Manager at Deloitte & Touche. Business Administration, University of Passau, Germany.
Track Record: Altra grew from small-cap industrial to mid-cap during his tenure, culminating in a $7B acquisition by Regal Rexnord in 2023. Described as having "played an instrumental role in growing the business." He was at Altra during its most active M&A period, including international acquisitions. Retired January 2022 — was out of an active CFO role for four years before Cornerstone.
Assessment: Interim means temporary mandate. Not building a career here. Focused on stabilization and execution. German-trained, Deloitte-pedigreed: methodical, process-oriented, numbers-driven. At 66 with nothing to prove, he will evaluate SLB proposals on pure financial merit. He has seen complex capital structures at Altra — SLBs will not be unfamiliar. Best contact point for financial proposals. Vulnerability: he is a bridge. A permanent CFO may have different views.

Rose Lee — Former CEO (resigned March 18, 2025)
Background: First female Korean American to lead a Fortune 1000 company. Previously President of DuPont's Water & Protection business. 15 years at Saint-Gobain in general management, strategic planning, and IT. Cornell, RPI, and MIT degrees. Board member at Honeywell International. Served as Cornerstone CEO from September 2021 to March 2025.
What happened: She oversaw $957M in debt-funded acquisitions that produced a 32% EBITDA miss ($626M actual vs $918M pro forma target). Presented the Q4 2024 results to lenders on March 17. Resigned the next morning citing a "personal family matter."
Sources: BusinessWire Aug 4, 2021; Authority Magazine interview; Honeywell board page; Cornerstone 8-K Mar 18, 2025
Jeffrey Lee — Former CFO (resigned December 29, 2025)
Background: CFO for nearly 7 years (June 2019 to February 2026), spanning the entire CD&R era. Previously CFO at Wilsonart International, Contech, and Kennametal. 12 years at Eaton Corporation. BS University of Utah, MBA Duke University.
Assessment: He oversaw the $957M in acquisitions, the EBITDA collapse, and the material weakness. Left citing "another professional opportunity" — seven weeks before creditors organized. His departure clears the deck for restructuring.

Tina Beskid — SVP, Chief Accounting Officer (since April 1, 2025)
Background: Previously SVP and CAO at Resideo Technologies. Before that, VP of Finance and Investor Relations at Cornerstone Building Brands from 2019 to 2022 — a boomerang hire who knows where the bodies are buried. 8 years at Timken/TimkenSteel. Earlier career at Caterpillar, Eaton, and 6 years at Deloitte & Touche. CPA and CGMA. John Carroll University.
Assessment: Coming back to a material weakness she did not create gives her clean hands. She is the person signing the financials now and the person ERP remediation runs through.

The Suzanne Stefany Connection
This is the most important finding in the management workup.
- PJT Partners is Cornerstone's restructuring financial advisor (engaged February 2026).
- Suzanne Stefany was a Partner at PJT Partners from 2017 to 2024 and remains a Senior Advisor. At PJT she "advises companies in the industrials space on global corporate transformations and complex situations."
- She was appointed to Cornerstone's board in June 2025 — before restructuring was public but when the board already knew the trajectory.
- She previously served on JELD-WEN's board as Lead Independent Director — JELD-WEN is executing SLBs right now.
Stefany is the connective tissue between Cornerstone's board, PJT's advisory practice, and JELD-WEN's SLB playbook. She will not take cold calls. But understanding her network tells you: PJT Partners already has SLB precedent knowledge through her, and the board has a member who has seen SLBs work at a direct competitor. The path to the deal runs through PJT, through Stefany's credibility on the board, to CD&R approval.
Segment Presidents — The Operational Layer
| Segment | President | Tenure | Background |
|---|---|---|---|
| Windows & Doors | Vishal Singh | Jan 2026 | Masco (BrassCraft, Milgard Windows), Oldcastle (27 mfg facilities), Eaton. MBA Case Western. |
| Siding | Melissa Jones | Jul 2022 | 20+ yrs industrial. Stable under CD&R era. |
| Metal Solutions | Matthew Ackley | Apr 2021 | 20 yrs building materials, ex-USG Corp. Runs Mueller integration. |
| Canada | Lisa Domnisch | Aug 2023 | 20 yrs, ex-DuPont Water & Protection. |
Segment presidents are more stable than C-suite — Ackley (5 years), Jones (4 years), Domnisch (2.5 years). Only Singh is new (2 months). This layer runs the plants. They know which facilities are mission-critical versus marginal. Ackley oversees the Shelter Solutions PP&E — the best SLB candidate segment.

Approach Path
- Primary: PJT Partners — they are evaluating all liquidity options. Frame SLB as a tool in their restructuring toolkit.
- Secondary: CD&R real estate team — they executed the Multi-Color SLB, they know the playbook.
- Tertiary: Christian Storch (interim CFO) — he has financial authority and a stabilization mandate.
- Do not cold call Gunner Smith. He is 8 months in, building customer relationships, and will not respond to unsolicited real estate pitches. Go through his advisors.
