Key Topics Covered
Same-Store Sales Decomposition & Operating Leverage
Covers why SSS is more important than total revenue growth, how to decompose comps into traffic versus ticket to assess quality of growth, and why negative comps trigger disproportionate margin destruction through the fixed-cost operating leverage inherent in retail.
Unit Economics: Four-Wall EBITDA & Cash-on-Cash Returns
Walks through store-level profitability analysis, the calculation of cash-on-cash returns using net CapEx after tenant improvement allowances, and why the ramp curve from opening to mature AUV is critical for accurately modeling new unit payback periods.
Franchise vs. Company-Owned & Franchisor Valuation
Compares the margin profiles, CapEx intensity, and revenue stability of franchise royalty streams versus company-owned operations, and explains why franchisors trade at meaningfully higher EV/EBITDA multiples due to near-100 percent fee flow-through and insulation from store-level cost inflation.
Sale-Leasebacks, EBITDAR & Lease Accounting
Details how a sale-leaseback mechanically reduces EBITDA by replacing non-cash depreciation with cash rent expense, why EBITDAR creates apples-to-apples comparisons across owned versus leased retailers, and how PE firms use sale-leaseback arbitrage to turbocharge LBO IRRs.
Digital Disruption & Consumer Behavior
Covers the Amazon Effect on logistics and return costs, DTC versus third-party marketplace trade-offs around margin and customer data ownership, GMV-based valuation for early-stage marketplaces, the Lipstick Effect during recessions, and omnichannel versus multichannel integration strategies.
How to Prepare for Consumer/Retail (CRG) Interviews
Know the SSS decomposition framework cold: traffic versus ticket, and be ready to explain why traffic-driven growth is higher quality. The advanced session walks through exactly how to evaluate a five percent comp, and interviewers use this to test whether you can distinguish sustainable growth from unsustainable price increases.
Understand why grocery chains with negative working capital and flat growth can be superior LBO targets compared to high-growth apparel retailers. The sessions explain the cash-generative working capital dynamics, recession resilience, and lower CapEx that make stable consumer businesses attractive for leveraged transactions.
Practice walking through a sale-leaseback's impact on all three financial statements and valuation multiples. The advanced session shows how EBITDA decreases while the EV/EBITDA multiple mathematically increases, and interviewers frequently test whether candidates understand that this multiple expansion reflects higher risk, not better performance.
Master GMROI as a comparison tool that captures both margin quality and inventory velocity. The advanced session includes a full numerical calculation, and this metric is a strong differentiator in consumer retail interviews because it shows you understand the trade-off between high-margin slow-turnover and low-margin high-turnover business models.

IB Vine has excellent questions, especially multistep ones. In my experience I've gotten grilled on accretion/dilution, bond math, and merger model questions. IB Vine has great practice for all of those.

As a nontraditional transfer student who has been rendered unavailable to many resources at my university (Leadership positions at clubs, immediately behind the recruiting cycle, etc.) IB Vine has been an absolute game changer in my IB prep.

From my experience interviewing FT for IB, it’s not enough to just know the 400 questions anymore (it’s a good starting point) but to look at even more advanced questions. Would recommend IB Vine.

Just got off the phone with a kid who interned at a Dallas PE firm. He mentioned that IB Vine helped him secure that internship as well as his Summer Analyst offer, especially since he came from a non-target with no resources.
