### Step 01 — Business Overview & Value Chain

#### 1. Executive Summary

Six Flags Entertainment Corporation (NYSE: FUN) is North America's largest regional amusement-resort operator, formed through the July 2024 merger of Cedar Fair L.P. and legacy Six Flags Entertainment Corp. The combined entity operates 41 parks (reducing to ~34 after 2026 portfolio rationalization) spanning amusement parks, water parks, and resort properties across the US, Canada, and Mexico. [S1]

The company's value proposition: an affordable, close-to-home entertainment destination for middle-income suburban families, with a season-pass model that drives repeat visitation and smooths attendance across the operating season. The merger aimed to create scale efficiencies, a cross-network season pass, and $120M in cost synergies — but integration disruption, a legacy Six Flags attendance shortfall, and a $1.5B goodwill impairment charge dominated the first full combined year (FY2025). [S4]

#### 2. Business Model

##### Revenue Streams
| Revenue Type | Description | Approx. Mix (FY2025) |
|-------------|-------------|----------------------|
| Admissions | Gate revenue: single-day tickets, season passes, group sales | ~54% |
| In-Park Products | Food & beverage, merchandise, games, parking, accommodations | ~46% |

**Total FY2025 Revenue:** $3.10B | **Attendance:** 47.4M guests | **Per Capita:** $61.90 [S4]

##### Season Pass Model
Season passes are the cornerstone of the business model, particularly Cedar Fair's historical approach which Six Flags is now extending network-wide. A season pass purchased at one park in the FUN network provides access to multiple parks — increasing perceived value and driving repeat visits. Season pass holders typically visit 3-5x per year, dramatically improving attendance economics vs. single-day visitors.

##### Fixed-Cost Operating Leverage
The business has high fixed costs (park maintenance, staff, debt service, insurance) with variable revenues (attendance-driven). This creates significant operating leverage: when attendance falls (weather, economic weakness), EBITDA is disproportionately affected. FY2025 attendance of 47.4M was below management's expectations; the resulting earnings shortfall triggered the $1.5B goodwill impairment.

#### 3. Value Chain Layer Map

```
[Upstream]                  [Core Operations]                    [Guest-Facing]
Land/Real Estate      →     Park Design & Development    →      Admissions / Ticketing
Ride Manufacturers    →     Park Operations               →      In-Park Spend (F&B, retail)
Food/Bev Suppliers    →     Safety & Maintenance          →      Lodging / Resorts
Technology (apps)     →     Marketing & CRM               →      Seasonal Events
Seasonal Labor        →     Season Pass Platform          →      Group/Event Sales
```

**Key Value-Chain Observations:**
1. **Rides** are capital-intensive to acquire ($10M-$30M+ per major coaster) and multi-decade assets — once built, they anchor park identity and competitive position for 20-30 years
2. **Land** is owned (not leased) at most parks — creating a real-estate underpinning that EPR Properties recognized in buying 6 parks in April 2026
3. **Technology** is increasingly important: FUN is integrating ticketing platforms, mobile apps, and CRM systems to cross-sell and improve per capita yield
4. **Seasonal Labor** is a key cost variable; the company employs ~8,000 full-time and ~20,000 seasonal workers (peak estimate)

#### 4. Park Portfolio (as of Q1 2026, pre-remaining closings)

##### Tier 1: Core Growth Parks (Top 15 per management — Investor Day 2025)
| Park | Location | Notes |
|------|----------|-------|
| Cedar Point | Sandusky, OH | Flagship park; 12 consecutive years "Best Amusement Park in World" (Amusement Today) |
| Knott's Berry Farm | Buena Park, CA | Year-round park; LA metro area |
| Canada's Wonderland | Vaughan, ON | Largest park by annual attendance in Canada |
| Kings Island | Mason, OH | Cincinnati metro flagship |
| Carowinds | Charlotte, NC | Carolinas flagship |
| Kings Dominion | Doswell, VA | Mid-Atlantic flagship |
| Worlds of Adventure | Aurora, OH | Cleveland market |
| Six Flags Great Adventure | Jackson, NJ | NY/NJ metro |
| Six Flags Magic Mountain | Valencia, CA | Thrill rides capital; perennial season-pass draw |
| Six Flags Over Georgia | Austell, GA | Atlanta market |
| Six Flags Great America | Gurnee, IL | Chicago market |
| Six Flags Fiesta Texas | San Antonio, TX | Texas market |
| Schlitterbahn Waterpark New Braunfels | New Braunfels, TX | Water park |

##### Parks Being Divested (announced 2026, sold to EPR Properties for $331M total)
Valleyfair (MN), Worlds of Fun (MO), Michigan's Adventure (MI), Schlitterbahn Galveston (TX), Six Flags St. Louis (MO), Six Flags Great Escape (NY), Six Flags La Ronde (Montreal, QC — pending)

**Portfolio Rationale for Sales:** The 7 divested parks generated ~$260M revenue and only ~$45M EBITDA (~17% EBITDA margin), well below company average. Divestiture proceeds reduce debt and focus the portfolio on core high-EBITDA parks. [S14]

---

#### 5. Strategic Framework (Post-Merger)

**Three Strategic Pillars (Investor Day 2025) [S9]:**
1. **Attendance Recovery:** Recapture 10M+ lost visits by 2028; >80% from season pass expansion and visit frequency
2. **Per Capita Spending Growth:** 90% from increased transaction volume + higher per-transaction averages; food & beverage revamp (50+ locations)
3. **Cost Discipline:** $60M opex reduction in 2025 and 2026 each; from 2027 cost growth at/below inflation; $120M integration synergy target

**2028 Financial Targets:**
- Revenue: $3.8B
- Adj EBITDA: $1.5B (40% margin)
- Attendance: 58M guests
- Pre-tax FCF: $800M (Project Accelerate target by 2027)
- Net Leverage: <4.0x by end of 2026

#### 6. Key Management (Post-Merger Leadership)

| Name | Role | Background |
|------|------|------------|
| John Reilly | President & CEO (Dec 2025–) | 30+ yrs amusement industry; prior CEO Palace Entertainment, COO Parques Reunidos |
| Richard Zimmerman | Former CEO (retired Dec 8, 2025) | Led Cedar Fair through COVID and merger |
| Brian Witherow | Former CFO (departed May 8, 2026) | Cedar Fair CFO pre-merger |
| Amy Martin Ziegenfuss | CMO | Former CMO Carnival Cruise Line |
| Marilyn Spiegel | Non-executive Chair (from Jan 1, 2026) | Replaced Selim Bassoul |
| Jonathan Brudnick | Board Director | Partner at Sachem Head Capital (active investor) |

**CEO Transition Risk:** New CEO John Reilly took the helm December 2025 — simultaneously the company faces integration challenges, portfolio rationalization, and a deleveraging target. The CFO also departed May 2026. This leadership transition creates execution risk at a critical juncture. [S15]

## Recent Catalysts

step: 12
title: Bull vs. Bear — Analyst Debate
date: 2026-05-27

### Step 12 — Catalysts: Bull vs. Bear

**Note:** Transcript analysis was NOT performed — this is the filings-and-consensus path. The bull/bear debate is constructed from earnings releases, SEC filings, consensus estimates, investor day materials, press articles, and published analyses. Management's verbal communication nuances and off-script remarks are not captured.

---

#### 1. The Central Debate

At ~$21/share (May 2026), FUN trades at approximately 9x EV/Adj EBITDA on FY2025's $792M. The bull-bear divide centers on a single question: **Can Six Flags execute its "Great Reset" and compound EBITDA toward $1.5B by 2028, while deleveraging from 6.4x to <4x?**

Bulls believe the company is Cedar Point in a distressed body — the core asset quality is high, the per capita trend is real, and the market is mispricing because of the FY2025 impairment optics. Bears believe the merger was a value-destroying event, the legacy Six Flags parks are structurally inferior, and the debt load will prevent value creation even if operations improve.

---

#### 2. Catalyst Map

##### Positive Catalysts
| Catalyst | Expected Timing | EBITDA Impact |
|----------|----------------|--------------|
| New ride openings at core parks (Cedar Point, Knott's, others) | Summer 2026 | +$30-60M attendance lift |
| F&B renovation program (50+ locations) | FY2026-2027 | +$5-8 per capita × 47M guests = +$235-376M revenue |
| Park divestiture debt reduction ($331M proceeds) | Q2 2026 | -$20-30M interest expense reduction |
| Season pass cross-network growth | Ongoing | Higher renewal rates + new members |
| Q2-Q3 2026 earnings beats (if weather cooperates) | Aug 2026 | Stock re-rating from beat |
| CEO Reilly proves operational execution | H2 2026 | Confidence in 2028 targets |
| Leverage falling below 5x milestone | Late 2026 | Multiple re-rating catalyst |
| Interest rate cuts (Fed) | 2026-2027 | Floating rate term loan savings |

##### Negative Catalysts
| Catalyst | Expected Timing | EBITDA Impact |
|----------|----------------|--------------|
| Poor summer weather (rain/heat) in key markets | Summer 2026 | -$50-120M |
| Attendance misses Q2-Q3 consensus | Aug-Nov 2026 | Stock -20-30% |
| CFO vacancy creates governance uncertainty | Ongoing | Multiple compression |
| Consumer recession (tariff impact) | 2026-2027 | -5-10% attendance |
| Interest expense spike on floating rate | Rate-dependent | -$15M per 100bps |
| Covenants tested (if EBITDA misses) | Late 2026 | Distress pricing |
| Continued impairment (if remaining goodwill impaired) | Any quarter | Non-cash but optics negative |

---

#### 3. The Bull Case

**Thesis:** Six Flags is Cedar Point-quality real estate in a temporary restructuring. The per capita trajectory, cost synergy execution, and portfolio rationalization are all working. The impairment is a non-cash accounting item, not an economic loss. At $21/share, the stock discounts execution to zero and offers asymmetric upside to 2028 targets.

**Base Financial Case (Bull):**
- FY2026E Adj EBITDA: ~$870M (cost synergies + per capita growth, portfolio sales neutral-to-positive)
- FY2027E Adj EBITDA: ~$1.05B (Project Accelerate momentum; attendance +3-5M from new rides)
- At 10x EV/EBITDA and $4.5B net debt → equity value = $10.5B − $4.5B = $6.0B / 102M shares = **$59/share**
- Upside from current: ~+180%

##### Bull Case — 3 Key Bullets
- **Per capita spending is a structurally durable earnings compounder:** FUN's admissions and in-park per capita are consistently growing 5-8% annually through pricing power, F&B upgrades, and premium product introduction. If per capita reaches $70+ by 2027 on 50M+ guests, revenue alone exceeds $3.5B — enough to drive $1.0B+ EBITDA even before full synergy realization.
- **The real estate moat is deeply undervalued:** EPR Properties paid 7.4x EBITDA for the worst 7 parks in the portfolio. The top 15 parks — Cedar Point, Knott's, Canada's Wonderland, Kings Island — have meaningfully higher EBITDA multiples in a normalized sale. The market is valuing the whole company at ~9x, implying the core parks are worth far more than the market cap.
- **Portfolio rationalization accelerates deleveraging and margin expansion:** Selling the 7 below-average parks simultaneously reduces debt by ~$285M (net) and eliminates $260M of low-margin revenue. Pro-forma Adj EBITDA margin on the retained portfolio approaches 30%, narrowing the gap to United Parks and supporting multiple expansion toward 10-12x EV/EBITDA.

---

#### 4. The Bear Case

**Thesis:** The Cedar Fair + Six Flags merger was a value-destructive deal executed at the top of the cycle. Legacy Six Flags parks are structural underperformers that will require years of deferred-maintenance remediation and attendance rebuilding. The $5.1B debt load consumes all free cash flow, prevents meaningful reinvestment, and will require either dilutive equity issuance or continued asset sales at distressed multiples. Management transitions compounding integration risk.

**Bear Financial Case:**
- FY2026E Adj EBITDA: ~$750-780M (consumer softness, weather drag, integration friction)
- FY2027E Adj EBITDA: ~$820-850M (slow recovery, cost savings partially offset by labor)
- At 7x EV/EBITDA (distress discount) and $4.8B net debt → equity value = $5.95B − $4.8B = $1.15B / 102M shares = **$11.30/share**
- Downside from current: ~-46%

##### Bear Case — 3 Key Bullets
- **Six Flags legacy parks are a long-term structural drag that won't be fixed by F&B renovations:** The former Six Flags parks primarily serve urban/suburban markets with shorter operating seasons, older ride inventories, and deferred maintenance relative to Cedar Fair parks. Attendance at these parks declined for years before the merger — the underlying consumer preference has shifted against them, not toward them.
- **The debt load leaves no margin of safety:** At 6.4x net leverage with $360M annual interest expense, any attendance miss or summer weather event directly threatens covenant compliance. A 10% EBITDA miss ($79M) would push leverage to ~7x — potentially triggering covenant cure mechanisms, amendments, or in a stress case, equity issuance at dilutive prices.
- **Multiple expansion requires execution credibility that management has not yet established:** The 2028 targets ($1.5B EBITDA, 40% margin, 58M attendance) require compounding growth from a base where FY2025 attendance of 47.4M fell well short. A new CEO (8 months in), no permanent CFO, and an activist investor on the board create governance uncertainty that suppresses re-rating potential regardless of operational progress.
