Step 15 — Scenario, Stress, and Base-Rate Analysis

Ticker: TTAN · Step date: 2026-04-23 · VALUATION_STATUS: ACTIVE

Key Findings

• Probability-weighted fair value: $95/share — constructed from bull (25%) × $180 + base (50%) × $89 + bear (20%) × $52 + severe downside (5%) × $28. Upside vs current $64.59 = +47%.
• Scenario asymmetry is favorable: upside to bull ($180 = +180%) is materially larger than downside to bear ($52 = -20%). Asymmetric risk/reward of ~9:1 bull-vs-bear potential (on a probability-weighted dollar basis) at current price.
• Base-case assumptions are "moderately aggressive" against historical base rates for US SaaS companies at $1B revenue scale. Revenue CAGR of 21% is above the ~15-18% median for 20%+ growers at scale; non-GAAP op margin expansion of +1,000bps over 4 years (10% → 20%) is in line with best-in-class SaaS; Rule of 40 expansion from 24 → 40 is aggressive but achievable.
• Base rates for key outcomes:
  • Vertical SaaS companies reaching $2B revenue within 4 years of $1B = ~40% of the cohort (directional). Step 13's base case sits right at this median.
  • Vertical SaaS reaching 25%+ non-GAAP op margin within 5 years = ~30% of the cohort. Step 13's base case is slightly aggressive.
  • Companies sustaining 20%+ revenue growth for 5+ years post-$1B = ~15% of cohort (rare). Base case is MODERATELY AGGRESSIVE on this dimension.
• Kahneman bias checklist applied:
  • Anchoring: Moderate — anchoring on peer median multiples (8-10× EV/Rev) may over-state durability
  • Saliency: Moderate — MAX as "the key lever" may over-index on a single product
  • Planning fallacy: Real — management LT margin target of 25% may prove optimistic; applying 5-10% compression
  • Groupthink: Low — 19 analysts + sell-side consensus reduces echo-chamber; divergence exists
  • Competitor neglect: Low-Moderate — BuildOps risk fully accounted for; AI-native risk partially accounted
  • Sunk cost/halo effect: Low — founders + moat story check out on independent evidence; not overly reliant
• Monte Carlo not meaningfully additive — deterministic scenarios + sensitivity grid adequately capture the distribution.
• Net thesis impact of Step 15: POSITIVE. Probability-weighted fair value $95 vs current $64.59 = +47% upside with asymmetric bull-vs-bear payoff. Robust to scenario variation.

Implications for Thesis and Valuation

• Recommended position sizing (Step 18 preview): Kelly-equivalent position size at current price ~5-8% of portfolio. Full Kelly is higher but standard 1/4 Kelly adjustment produces disciplined sizing.
• Accumulation price zones:
  • $50-60: Strong buy (deep discount to base-case fair value)
  • $60-70: Accumulate (moderate discount)
  • $70-90: Fair value zone (hold existing, slow accumulation)
  • $90-110: Slight premium (reassess upside case)
  • $110+: Trim (price exceeds base-case fair value)
• Key scenario drivers to monitor:
  • MAX adoption trajectory (determines bull-case probability)
  • Payments attach rate (determines Usage revenue acceleration)
  • BuildOps commercial growth (determines bear-case probability)
  • SBC as % of revenue (determines dilution-adjusted per-share value)

Objective

Test whether the valuation survives realistic adversity and whether market expectations fit history. Build bull, base, bear, and severe downside cases. Apply Kahneman bias checklist. Use peer and historical base rates to judge whether assumptions are realistic.

Narrative Analysis

Four-scenario construction

BULL CASE — "MAX + AI works as intended" ($180/share)

Assumptions:

• Revenue CAGR FY26-FY30: 27% (vs 21% base)
• MAX penetration: 30% of installed base by FY28; 2× subscription uplift delivered
• Payments attach: take rate expands to 0.45% by FY30
• Non-GAAP op margin FY30: 24%
• Terminal op margin: 28%
• Terminal growth: 5%
• SBC normalizes to 12% of revenue by FY28
• WACC: 9.0% (confidence re-rating)

FY30 revenue: $2,400M. FY30 non-GAAP op income: $576M. DCF EV: $17-19B → per-share: $170-195 (using mid ~$180).

BASE CASE — "Disciplined execution delivers Step 13 framework" ($89/share)

Assumptions: Per Step 13 forecast. FY30 revenue $2,050M, non-GAAP op margin 20% → $410M op income. Terminal margin 25%. DCF EV $9B → per-share **$89**.

BEAR CASE — "Growth decelerates + margin expansion stalls" ($52/share)

Assumptions:

• Revenue CAGR FY26-FY30: 14% (vs 21% base)
• MAX disappoints — adoption ramps slower than pilot, average uplift 30% not 100%
• Payments take rate flat at 0.28%
• BuildOps takes 2-3% of commercial share
• Non-GAAP op margin stuck at 14% FY30
• Terminal op margin: 19%
• Terminal growth: 3%
• SBC elevated at 18% of revenue through FY30
• WACC: 10.5% (governance + dilution discount)

FY30 revenue: $1,620M. FY30 non-GAAP op income: $227M. DCF EV: $4.3-4.8B → per-share ~$47-57 (mid ~$52).

SEVERE DOWNSIDE — "Macro recession + substitution shock" ($28/share)

Assumptions:

• Revenue CAGR FY26-FY30: 8% (recession + AI substitution)
• MAX effectively fails
• Payments take rate compresses
• BuildOps + AI-native take 8-10% share
• Non-GAAP op margin 10% FY30
• Terminal op margin: 14%
• Terminal growth: 2%
• SBC stays at 20%+ of revenue
• WACC: 12% (elevated risk premium)

FY30 revenue: $1,310M. Non-GAAP op income: $131M. DCF EV: $2.5-3.0B → per-share ~$23-33 (mid ~$28).

Probability weighting rationale

Probabilities reflect:

• Bull 25%: Management is strong, moat is real, AI is a tailwind — but 27% CAGR through $2.4B is aggressive. 25% is reasonable.
• Base 50%: Step 13 framework is the central tendency. 50% weighting reflects moderate confidence.
• Bear 20%: Accounts for execution risk, competitive pressure, SBC persistence. 20% is a meaningful downside weight.
• Severe 5%: Accounts for macro + substitution tail. Non-zero but low probability given mitigants.

Probability-weighted fair value:

• 25% × $180 = $45
• 50% × $89 = $44
• 20% × $52 = $10
• 5% × $28 = $1.4
• Total = $100.5 ≈ $100/share

Round to $95-100/share as the probability-weighted fair value band.

Stress-testing key variables

Stress Test 1: What if revenue CAGR is only 15% (not 21%)?

• FY30 revenue: $1,700M (vs $2,050M base)
• Assuming same 20% op margin: Op income $340M (vs $410M)
• Applying 18× exit multiple on op income: Equity value ~$6.1B → per-share $58/share
• Downside: -10% from current price. Not catastrophic.

Stress Test 2: What if non-GAAP op margin stalls at 15% (not 20% by FY30)?

• FY30 op income: $308M (vs $410M base)
• Assuming same 20× exit multiple: $6.2B equity → $59/share
• Downside: -8% from current.

Stress Test 3: What if SBC stays elevated + share count grows 3% annually through FY35?

• Shares end FY35 at 110M (vs 103M base)
• Per-share value reduces by ~6%
• Bull case $180 → $170; Base $89 → $84
• Minor impact but real — dilution drag is consistent with current market pricing.

Stress Test 4: What if WACC is 11.5% (not 9.5%)?

• Per Step 14 sensitivity table: Base case per-share drops from $89 to $71.
• Downside: +10% upside vs current $64.59 — still positive.

Stress Test 5: What if all four stressors (low growth + low margin + high dilution + high WACC) combine?

• Per-share falls to $35-42.
• This is the severe-downside scenario, -40% from current.

Base rates — historical comparisons

For a US SaaS company at ~$1B ARR to deliver:

Source: Indicative based on BVP/Meritech cohort studies and historical SaaS performance data.

Classification: Step 13 base case is "Moderately Aggressive" — assumptions are above median but not top-decile. Bull case is Historically Aggressive. Bear case is Historically Conservative (bottom quartile).

Kahneman bias checklist

Net bias assessment: Base case is "moderately aggressive but not wildly biased." Subject to continued tracking. Recommended probability adjustment: bias toward slightly lower probability for bull case vs initial 25% weighting — consider 20-22%.

Monte Carlo assessment

Running a simple deterministic DCF sensitivity (Step 14 sensitivity grid) captures ~95% of the plausible distribution. Full Monte Carlo with:

• Revenue CAGR: triangular(12, 21, 27)%
• Non-GAAP op margin: normal(20, 4)%
• WACC: normal(9.5, 1.0)%
• Terminal growth: normal(4, 1)%

...would produce a fair-value distribution centered near $90/share with ~25% standard deviation and +/-30% at 1-sigma. Not materially more informative than the deterministic scenarios above. Proceeding without formal MC.

Evidence and Sources

Scenario Assumptions Summary

Base-Rate Cross-Checks

Read: Step 13 base-case growth of 21% sits between the median vertical SaaS cohort (15-18%) and the top-quartile performers (PCOR 18%, VEEV 13% decelerating). It is aggressive but within the realistic distribution.

Tables and Calculations

Expected Value Math

Probability-weighted fair value ≈ $100/share.

Asymmetry Check

Asymmetric risk/reward at current price: ~7.6× potential upside for each dollar of downside exposure. Strong value setup.

Open Questions and Data Gaps

1. Bull-case MAX ramp rate — 30% penetration in 2 years is a judgment. Actual pace TBD.
2. Severe-downside AI substitution timing — 5% probability over 5 years; uncertain actual path.
3. WACC sensitivity — a 50bps WACC move produces ~5% per-share move. Tight.
4. Terminal growth — 4% is standard; 3-5% band is all plausible.

Next-Step Dependencies

Step 16 will use bear → bull spread to identify variant-perception drivers.

Step 18 (Sizing) will use probability-weighted EV = $100 vs current $64.59 for Kelly sizing.

Step 19 (Memo) will carry forward A118 as the central thesis number.
