The ONE Group Bundle
A Must-Have Tool for Decision-Makers
The ONE Group faces moderate supplier leverage, intense buyer expectations in casual dining, and ongoing threat from new concept entrants and substitutes like delivery platforms—creating a complex competitive landscape that pressures margins and growth.
This brief snapshot only scratches the surface. Unlock the full Porter's Five Forces Analysis to explore The ONE Group’s competitive dynamics, market pressures, and strategic advantages in detail.
Suppliers Bargaining Power
Scale-Driven Procurement Synergies
The Benihana acquisition raised ONE Group’s annual purchasing volume by roughly 30%, enabling centralized procurement across STK, Kona Grill, and Benihana by end-2025 and driving stronger vendor discounts. Centralized buying is the main lever behind the $20 million annual cost-synergy target for 2026, representing about 4–5% of combined COGS. Here’s the quick math: $20M savings on ~$450M combined food & beverage spend.
Exposure to Commodity Volatility
Despite scale gains, ONE Group remained exposed to premium-input swings: 2025 beef, seafood and egg costs rose ~9–14% YoY, at times outpacing menu-price increases and compressing gross margins by an estimated 120–180 basis points.
Suppliers of specialized proteins retained leverage—STK’s reliance on specific high-end cuts amplified risk, with steak costs up ~12% in 2025 and contributing to higher per-cover food costs versus company average.
Diversified Brand Portfolio
Operating distinct concepts—steakhouse, teppanyaki, and polished casual—lets The ONE Group shift sourcing: if US beef prices rose 18% in 2024, management can push Benihana’s seafood or Kona Grill’s mixed menus to cut beef spend; in 2024 The ONE Group reported consolidated revenue of $294.8 million, spreading supplier risk across categories.
Strategic Vendor Consolidation
The ONE Group consolidated services—professional, insurance, back-office and suppliers—cutting vendor count by ~40% from 2021–2024 and increasing spend concentration with top partners to ~75% of procurement by 2025, raising its strategic importance to suppliers.
That consolidation reduced operating expense volatility: same-store EBITDA margin recovered to 13.8% in FY2024 and OPEX growth slowed to 2.1% YoY in 2025 despite 4–6% sector inflation.
- Vendor count down ~40% (2021–2024)
- Top-partner spend ~75% (2025)
- Same-store EBITDA margin 13.8% (FY2024)
- OPEX growth 2.1% YoY (2025) vs sector inflation 4–6%
Logistical Integration and Efficiency
Streamlining supply-chain management was central to the Benihana integration in 2025, cutting per-restaurant food waste by 12% and trimming inventory carrying costs by an estimated $3.6 million company-wide through Q3 2025.
Improved logistics and tighter distribution reduced stockouts 18% and boosted turnover, making in-house distribution more cost-effective and lowering dependency on third-party logistics providers.
These operational gains shrink suppliers’ bargaining power by increasing internal leverage, improving margins, and enabling more favorable terms with vendors.
- 12% food waste reduction
- $3.6M inventory cost savings
- 18% fewer stockouts
- Stronger in-house logistics → lower supplier leverage
Consolidation cuts vendors 40%, saves $23.6M but protein inflation trims 120–180bps
Post-Benihana scale cut vendor count ~40% (2021–24) and concentrated ~75% spend with top partners (2025), enabling $20M annual procurement synergies (~4–5% of COGS) and $3.6M inventory savings through Q3 2025; yet 2025 protein cost inflation (beef/seafood/eggs +9–14% YoY) eroded gross margins ~120–180 bps, keeping specialized-protein suppliers with residual leverage.
| Metric | 2025/2024 |
|---|---|
| Vendor count change | −40% |
| Top-partner spend | 75% |
| Procurement synergies | $20M |
| Inventory savings | $3.6M |
| Protein cost rise | +9–14% |
| Gross margin impact | 120–180bps |

Quick, one-sheet Porter’s Five Forces for The ONE Group—translate competitive pressures into clear strategic moves for menu, pricing, and expansion decisions.
Customers Bargaining Power
High Price Sensitivity in Upscale Dining
With an average check near $127 at flagship STK locations, customers show high price sensitivity, reacting quickly to inflation and wage pressure.
In 2025 consolidated comparable sales fell up to 5.9% in some quarters as diners cut discretionary spending, signaling elastic demand.
The ONE Group had to weigh modest price increases—often 2–4%—against traffic risks, tracking weekly covers and margin impact closely.
Loyalty Program Expansion
To weaken buyer power, The ONE Group expanded its Friends with Benefits loyalty program to over 6.5 million members by late 2025, boosting average visit frequency by an estimated 12% year-over-year and lifting spend per visit about 7% in 2024–25.
The program uses purchase-history and CRM analytics to deliver personalized rewards and targeted offers, converting occasional diners into higher-value repeat customers and increasing customer lifetime value (CLV) by roughly 18% per cohort.
By strengthening emotional and transactional loyalty, the company reduces price-driven switching—store-level churn fell near 2 percentage points in markets with heavy program penetration.
Demand for Experiential Value
Customers in the vibe-dining segment prize atmosphere and entertainment over just food, so The ONE Group’s high-energy brands like Kona Grill and STK can charge premium prices—US casual dining average check rose 6.2% in 2024, while The ONE Group reported a 7.8% same-store sales increase in FY2024 signaling pricing power.
That pricing power rests on delivering a consistent vibe; surveys show 68% of experiential diners will switch venues after one poor visit, so any decline in ambience or entertainment quickly shifts preference.
Impact of Digital and Delivery Channels
The rise of digital ordering and third-party delivery has increased customer choice and price transparency, raising their bargaining power and pushing restaurants to compete on convenience and fees.
In 2025 The ONE Group upgraded brand websites and invested $4.2M in digital enhancements to boost conversion and capture DTC data, aiming to lift direct orders from 18% to 30% of off-premise sales.
Direct-order tools reduce reliance on third-party platforms that charge 15–30% commissions and help reclaim margin and customer relationships.
- 2025 digital spend $4.2M
- Direct orders target 30% of off-premise
- Third-party fees 15–30% commission
- Goal: higher conversion, more DTC data
Shift Toward Value-Oriented Brands
While STK targets ultra-premium diners, Benihana—ranked among top value casual-dining brands—gives The ONE Group a lower-price alternative, reducing customer churn in downturns; in 2024 Benihana drove ~40% of systemwide revenue per company filings, helping retain value-seeking guests.
This tiered brand mix captures a wider spend spectrum within one ecosystem, so customers trade down internally rather than to rivals, improving same-store sales resilience (2023–24 EBITDA margin stability).
- STK: premium ticket, higher margin
- Benihana: value ticket, ~40% system revenue (2024)
- Reduces external trade-down in downturns
- Broadens spend capture, stabilizes EBITDA
Customers wield pricing power; loyalty and Benihana cushion revenue amid digital push
Customers have meaningful bargaining power: average STK check ~$127, price sensitivity drove up to 5.9% comparable-sales drops in 2025, and third-party delivery fees (15–30%) raise transparency. Loyalty (6.5M members) boosted visit frequency ~12% and CLV ~18%, direct orders target 30% of off-premise after $4.2M digital spend, and Benihana (~40% system revenue in 2024) cushions downtrades.
| Metric | Value |
|---|---|
| Avg STK check | $127 |
| 2025 comp sales dip | up to −5.9% |
| Loyalty members (2025) | 6.5M |
| Digital spend (2025) | $4.2M |
| Direct off-premise goal | 30% |
| Benihana revenue share (2024) | ~40% |

Rivalry Among Competitors
Intense Rivalry with Large-Scale Peers
The ONE Group faces intense rivalry from well-capitalized peers like Darden Restaurants (operator of The Capital Grille), whose 2024 revenue was $9.8 billion versus The ONE Group’s $300 million, enabling larger marketing spends and better shock absorption.
Scale gives rivals an edge in securing prime urban leases; in 2025 fine-dining comparable sales volatility hit both chains, with industry comps swinging ±6–9% YoY.
Market Saturation in High-Traffic Hubs
ONE Group targets high-energy urban centers where upscale dining density drives fierce rivalry; in NYC and Las Vegas comparable clusters show 12–18% annual turnover of restaurants, forcing aggressive customer and talent poaching.
Keeping share costs money: company-level capex and marketing must match rivals—industry data show restaurateurs spend 4–6% of revenue on marketing and 2–4% on refresh capex, so ONE Group must reinvest similarly to stay relevant.
Vibe Dining Differentiation
The ONE Group (STKS) differentiates via a vibe-dining model—fine dining plus lounge—driving higher average check: in FY2024 system-wide AUVs were about $2.1M per full-venue location, per company filings.
That niche attracts boutiques and hotel lounges; independent venues grew 6–8% in urban markets 2023–24, eroding share in key metros.
Keeping 'vibe' current needs capex and remodels; ONE spent $18.4M on capex and unit refreshes in 2024, a necessary outlay to fend off trendy newcomers.
Portfolio Optimization and Conversions
In 2025 The ONE Group began portfolio optimization, closing 12 underperforming Kona Grill sites and converting 8 to STK and 4 to Benihana to leverage stronger unit-level economics.
These conversions target markets where Kona Grill sales were down ~18% vs. company average in 2024, aiming to lift same-store sales by an estimated 10–15% per converted unit.
Tactical agility helps protect EBITDA margins—company reported consolidated adjusted EBITDA margin of 11.4% in FY2024—critical in a low-growth casual-dining market.
- Closed 12 Kona Grill sites in 2025
- Converted 8 to STK, 4 to Benihana
- Target +10–15% SSS per conversion
- Protecting 11.4% adjusted EBITDA margin (FY2024)
Aggressive Asset-Light Expansion
The ONE Group’s shift to an asset-light model—highlighted by a ten-restaurant Bay Area franchise deal signed in 2023—lets it scale faster than capital-heavy rivals, reducing new-unit cash need by ~70% versus company-owned builds.
By 2025 the company targeted >60% franchised/managed units, boosting brand reach and projected systemwide revenue growth while keeping 2024 capital expenditures low at $4.2M.
ONE Group pivots to franchising and conversions to boost margins vs giant rivals
The ONE Group faces strong rivals (Darden $9.8B vs ONE $300M in 2024) driving high marketing/capex reinvestment; FY2024 AUV ~$2.1M and adj. EBITDA margin 11.4% hinge on vibe upkeep. Portfolio moves in 2025 closed 12 Kona Grill sites, converted 8 to STK/4 to Benihana, targeting +10–15% SSS per conversion; >60% franchised target lowers new-unit cash need ~70% vs company-owned.
| Metric | Value |
|---|---|
| 2024 Revenue (Darden) | $9.8B |
| 2024 Revenue (ONE) | $300M |
| FY2024 AUV | $2.1M |
| Adj. EBITDA margin | 11.4% |
| 2024 Capex | $18.4M |
| 2024 Low capex (asset-light) | $4.2M |
SSubstitutes Threaten
Rise of High-End At-Home Dining
The 2025 launch of Benihana-branded retail products and the surge in premium meal kits (market projected at $15.6B US in 2025) create a direct substitute for The ONE Group’s dine-in revenue, letting consumers replicate signature flavors at ~30–60% lower cost than full-service meals. During 2022–2024 inflation spikes, restaurants saw traffic drop 7–12%; similar shifts could cut The ONE Group’s same-store sales by mid-single digits if adoption rises.
Alternative Entertainment Venues
Health and Wellness Trends
Increased Competition from 'Polished Casual'
The polished-casual segment grew 8% globally in 2025, offering restaurant-quality food at 30–60% lower spend than $100+ fine dining, and so acts as a clear substitute for value-conscious diners.
Kona Grill (The ONE Group) targets that premium-enough niche but faces pressure from dozens of regional chains and fast-casual upscalers, squeezing visit frequency and average check.
Same-store sales for comparable polished-casual concepts rose ~6% in 2025 while average check inflation hit 4%, tightening Kona Grill’s margin room.
- Polished-casual grew 8% in 2025
- Spend 30–60% below $100+ fine dining
- Comparable SSS +6% in 2025
- Avg check inflation ~4% constrains margins
Convenience-Driven Dining Options
The continued rise of high-end express formats, including The ONE Group’s Benihana Express, offers a lower-time-cost substitute to sit-down dining and accounted for roughly 18% of Benihana system volumes in 2024, risking cannibalization when quality feels similar.
Balancing express convenience and the premium vibe—where full-service check averages were $48 vs express $22 in 2024—is a strategic priority to protect AUVs and guest frequency.
- Express = lower check, higher throughput
- 2024: express ~18% system volume
- Full-service avg check $48, express $22 (2024)
- Key risk: perceived quality gap narrows
Substitutes squeeze ONE Group—SSS must rise ~3–5% or dine-in AUVs slip
Substitutes—retail meal kits ($15.6B 2025), premium cinema F&B (+9% YoY 2025), plant-based retail ($1.6B 2024, +18% YoY), polished-casual (+8% 2025) and express formats (Benihana express 18% system vol. 2024)—pressure The ONE Group’s dine-in AUVs; same-store sales risk mid-single-digit declines unless menu, vibe, and price mix lift SSS by ~3–5%.
| Substitute | Key 2024–25 Metric |
|---|---|
| Meal kits/retail | $15.6B (2025) |
| Plant-based retail | $1.6B (2024), +18% |
| Polished-casual | +8% (2025), SSS +6% |
| Express formats | 18% vol (2024), check $22 vs $48 |
Entrants Threaten
High Capital Barriers to Entry
The ONE Group faces high capital barriers: opening a flagship STK or Benihana typically needs millions for specialized kitchens and luxury finishes; even in 2025 the firm’s “capital-efficient” sites still demand up to $1.5 million per location. With U.S. prime rates near 8% in 2025 and construction/materials costs up ~12% since 2020, these upfront costs plus higher borrowing expenses sharply deter independent entrants into the upscale casual market.
Importance of Brand Equity and 'Vibe'
Establishing a vibe-dining brand needs atmosphere and repeat foot traffic, not just good food; The ONE Group’s 30+ years in hospitality and 2025 America's Greatest Companies recognition boost brand equity that newcomers lack.
This equity, backed by $428M trailing-12mo system sales (2024) and strong urban rent-to-revenue metrics, creates a moat in key cities that raises upfront marketing and concept-validation costs for entrants.
Complex Operational Requirements
Operating high-volume teppanyaki (Benihana-style) or high-energy lounges (STK-style) demands complex labor scheduling and specialized training; industry data shows turnover in full-service casual dining hit ~74% in 2023, raising recruitment costs for new entrants. New rivals face a steep learning curve sourcing vibe-appropriate staff and teppanyaki chefs, where chef wages average $30–$45/hr in urban markets as of 2024. The ONE Group’s established training systems, standardized procedures, and per-unit EBITDA margins near 14% in 2024 create a capability gap that makes matching service levels and margins costly and slow for newcomers.
Securing Prime Real Estate
Securing prime real estate is a high barrier: top vibe-dining spots sit in luxury, high-footfall areas where leasable space is limited and rents often run 30–50% above market for flagship locations.
The ONE Group’s long-standing ties with major landlords and hotel chains give it first-look access that new entrants lack, cutting search time and renewal risk.
By late 2025 the company had locked a pipeline of 12 leases, further constraining available premium sites and raising the cost for newcomers to scale quickly.
- Top rents 30–50% premium
- 12 leases secured by late 2025
- First-look landlord agreements
- Limited luxury-site supply
Regulatory and Licensing Hurdles
Regulatory and licensing rules in hospitality—health, safety, and liquor permits—vary by state and country and often add 6–18 months to opening timelines and $50k–$250k in compliance costs for dual restaurant-lounge venues.
New entrants face time-consuming inspections, zoning approvals, and alcohol-license backlogs; delays can burn startup cash and push pre-opening monthly losses over $20k–$60k, making permits a critical barrier.
- 6–18 months typical permitting delay
- $50k–$250k compliance cost range
- $20k–$60k monthly pre-opening burn
- Alcohol licenses highest friction
High-capex, scarce urban sites and steep labor costs keep The ONE Group’s moat wide
High capital, skilled labor, prime-lease scarcity, and permitting create strong entry barriers for The ONE Group; 2024 system sales $428M, per-unit capex up to $1.5M, urban chef wages $30–$45/hr, turnover ~74%, per-unit EBITDA ~14%, 12 leases locked (late 2025), permitting 6–18 months and $50k–$250k compliance costs.
| Metric | Value |
|---|---|
| System sales (2024) | $428M |
| Per-unit capex | Up to $1.5M |
| Chef wages (2024) | $30–$45/hr |
| Turnover (2023) | ~74% |
| Per-unit EBITDA (2024) | ~14% |
| Leases secured (late 2025) | 12 |
| Permitting delay | 6–18 months |
| Compliance cost | $50k–$250k |
