You are writing an internal investment committee memo for a long/short equity fund. Company (fictional): LedgerLift (ticker: LLLT) – B2B spend management + AP automation SaaS for mid-market enterprises. Use only the information below. Do NOT browse the web. This is a fictional exercise, not investment advice.

LedgerLift (LLLT) Investment Committee Memo

1. Recommendation: LONG | 12-Mo PT Range: $55-70 | Thesis

LedgerLift is a best-in-class mid-market SaaS leader in spend management and AP automation, evidenced by category-leading NRR of 123%, sub-6% logo churn, and 18-month CAC payback. Trading at a discount to comps medians on NTM revenue (7.4x vs. 9.0x) despite superior retention and expansion, with FCF inflection ahead on margin expansion.

2. Business + Why it Wins / Why Now

LedgerLift provides B2B spend management and AP automation SaaS to mid-market enterprises (6,200 customers, ARPA $132k). The business wins via sticky subscription revenue (92% mix, 82% GM), strong economics (94% gross retention, 123% NRR), and efficient go-to-market (34% S&M, 18-mo payback). Low concentration (top-10 16% of rev, top-1 3%) and revenue acceleration (FY23 $560m → FY24 $680m → FY25 $820m at ~21% YoY) signal durable moat in fragmented mid-market, where enterprises seek cost control amid economic uncertainty.

Why now: FY25 delivers 78% GM and 18% op margin inflection (services drag minimal at 8% mix/25% GM), with base FY26 growth/margins (21%/20%) setting up FCF ramp as growth moderates. Current $46 share price (EV $7.3B) embeds ~17% FY26 rev multiple vs. peers, derating quality.

3. KPI Quality Check + What Could Be Wrong

  • NRR 123%: Exceptional expansion (upsell/cross-sell), drives organic growth beyond net adds.
  • Logo churn 6%/yr: Elite for mid-market SaaS, implies high product stickiness.
  • CAC payback 18 months: Healthy ROI, supports S&M scaling (34% of FY25 rev).
  • Concentration: Benign (top-10 16%), mitigates single-name risk.

Potential issues: NRR could mask one-time large cohort expansions (probe customer-level data); churn may inflect with macro (mid-market sensitive); payback assumes stable ARPA (macro compression risk); hidden services losses or lengthening sales cycles could pressure GM/op margins.

4. Base/Bull/Bear DCF Model

Base Case (21/18/15/13/12% growth; 20/22/24/25/26% op margins; WACC 10%, term g 3%):

YearRevenue ($mm)EBIT ($mm)Unlevered FCF ($mm)
2026992198146
20271,171258191
20281,346323240
20291,521380284
20301,704443331

Key DCF Steps: Explicit FCF PV (2026-30) = $870mm. TV = 331 × (1+3%) / (10%-3%) = $4,865mm; PV = $3,022mm. Enterp. Value = $3,892mm. + Net cash $1.4B = Equity $5.3B ($28/share).

Bull Case (25/21/18/15/13% growth; 21/24/26/28/29% op margins; WACC 9%, term g 4%):

YearRevenue ($mm)EBIT ($mm)Unlevered FCF ($mm)
20261,025215159
20271,240298221
20281,463380283
20291,683471352
20301,902552413

Key Steps: Explicit PV = $1,069mm. TV = 413 × 1.04 / (9%-4%) = $8,590mm; PV = $5,581mm. EV = $6.7B. + Cash = Equity $8.1B ($42/share).

Bear Case (16/13/11/10/9% growth; 17/18/19/20/21% op margins; WACC 12%, term g 2%):

YearRevenue ($mm)EBIT ($mm)Unlevered FCF ($mm)
2026951162118
20271,074193142
20281,193227167
20291,312262194
20301,431300223

Key Steps: Explicit PV = $588mm. TV = 223 × 1.02 / (12%-2%) = $2,275mm; PV = $1,291mm. EV = $1.9B. + Cash = Equity $3.3B ($17/share).

DCFs conservative due to explicit deceleration and low terminal g; base implies 60% downside but assumes no perpetuity upside.

5. Comps Cross-Check

Fictional peers: EV/NTM Rev (7.0x, 9.0x, 11.0x; median 9.0x); EV/NTM EBIT (28x, 35x, 42x; median 35x). Use FY2026 as NTM proxy.

  • Rev: 9.0x × $992mm = $8.9B EV → +$1.4B cash = $10.3B equity → $54/share.
  • EBIT: 35x × $198mm = $6.9B EV → +$1.4B = $8.3B equity → $44/share.

Adjustments: No rev discount needed—superior NRR/churn justify parity to median despite mid-market focus/growth deceleration; EBIT at discount until 25%+ margins proven (peers likely higher growth). Blended comps $45-55/share supports PT low-end; bull FY26 ($1,025mm rev/$215mm EBIT) implies $47-56/share.

6. Catalysts (3), Risks (5), What Would Change My Mind (3)

Catalysts:

  1. FY25/Q4 beat on NRR/revenue, signaling guide raise into FY26.
  2. FY26 op margin >20% on S&M leverage, FCF >$150mm.
  3. Mid-market logo wins (ARPA expansion), top-10 revenue share <15%.

Risks:

  1. Macro headwinds compress mid-market spend budgets, slowing net adds.
  2. NRR reversion to <115% as expansions normalize.
  3. Competitive intensity (e.g., peers encroaching mid-market).
  4. Sticky S&M (34% rev) caps margin path to 26%.
  5. Unforeseen capex/D&A creep >3%/2.5% amid product investment.

Change My Mind (falsifiable):

  1. Q4 FY25 NRR <120% or logo churn >7%.
  2. FY26 revenue guide <19% growth.
  3. Top-5 customer ARR loss >2% of total revenue.

7. 10 Diligence Questions for Management

  1. What are the key drivers of 123% NRR (cohort-level upsell vs. pricing)? Sustainability into FY27?
  2. Breakdown of logo churn by vintage/customer size; any macro-exposed verticals?
  3. ARPA expansion mechanics: % from modules vs. seat growth? Risks to $132k stability?
  4. Services (8% rev): Path to <5% mix without GM dilution?
  5. CAC trends: Evidence of payback shortening below 18 months?
  6. Concentration details: Top-10 customer profiles, renewal rates, expansion potential?
  7. Competitive win rates/losses vs. named alternatives (e.g., peers A-C analogs).
  8. International exposure/plans: % rev, growth contribution by FY27?
  9. Capex/D&A assumptions: Product roadmap justifying 3%/2.5% of rev?
  10. LT margin path: Levers to 26%+ op margin; S&M efficiency benchmarks?
