Rating: Buy — Conviction: Low
Shift4 is still growing fast: Q2 payment volume +22%, organic GRLNF +11%. Even on filed GAAP numbers, after stock comp, deal costs and every capitalized cost, the base case sits above today's price with a 22% multiple de-rating built in. The call is levered: debt is ~5.4x FY2025 EBITDA on the model basis, so the bear case values the equity at zero and the result is sensitive to the discount rate.
Conviction tests (3a-v-c): T1 fail (Buy → Hold at +1pp: base return +34% → +10%) · T2 pass (Gordon +42%, exit +27%) · T3 pass · T4 pass
This is a much weaker Buy than on 2026-09-25. That model's aggregator EBITDA was 7% above the filed figure ($831mm vs $773mm) and missed most capitalized spending; rebuilt from the 10-K, base return falls from +122% to +34%.
Business overview
Shift4 bundles point-of-sale software, gateway and card acquiring for restaurants, hotels, stadiums, travel operators and retailers. Gross revenue was $4,180mm in FY2025 and $2,416mm in H1 2026 (+33%, helped by Global Blue, the tax-free-shopping business acquired July 2025). The company guides on gross revenue less network fees (GRLNF): $624mm in Q2 (+51%, +11% organic), of which payments-based GRLNF was $402mm.
Three variables drive earnings:
- Payment volume: $61bn in Q2, +22%.
- The blended take on that volume: payments GRLNF ÷ volume ≈ 66bp in Q2 (computed from the release).
- How much of GRLNF survives as cash profit. Adjusted EBITDA was 46% of GRLNF in Q2, but GAAP EBITDA was 18% lower ($238mm vs $284mm).
Competition
- Rivals. Toast, Fiserv's Clover and Block's Square in restaurants and hospitality; Adyen and Stripe for enterprise and international merchants.
- Where pressure shows first. In the take rate (~66bp) and organic GRLNF growth (+11% in Q2) before volume. Mizuho (2026-09-24) reads the H2 2026 guide as only ~9–13% growth. No competitor share datapoint was verified this session.
- Valuation. The market pays for net-cash software growth (Toast) and heavily discounts levered acquirers (Fiserv).
| Company (stockanalysis, 2026-09-28) | Forward P/E | EV/EBITDA | P/FCF | 52-week change |
|---|---|---|---|---|
| Shift4 | 6.7x | 7.9x | 6.8x | −53% |
| Fiserv | 6.3x | 6.7x | 6.3x | −64% |
| Global Payments | 5.9x | 9.0x | 27.2x | +1% |
| Toast | 19.8x | 32.9x | 30.2x | −19% |
Bull case
- Volume and international growth compound. 2026 volume guidance is $240–260bn (+15–24%), and Global Blue gives a cross-sell path into international merchants. Plays out if travel normalizes and volume growth stays near 20%. Model: rev_growth
- The gap between GAAP and adjusted EBITDA narrows. Acquisition and restructuring costs were $15mm and other adjustments $31mm in Q2. If Global Blue integration costs roll off and synergies land, GAAP EBITDA margin moves from 17.3% (H1 2026) toward 22%. Plays out if the adjusted-to-GAAP bridge shrinks through 2027. Model: ebitda_margin
- The multiple holds instead of compressing. The base case already assumes 8.0x, against today's 10.3x FY2025 on the model basis. Holding ~10x adds a lot to a thin equity slice. Plays out if two clean quarters restore trust in guidance. Model: exit_ev_ebitda
Bear case
- Travel and FX keep eroding the guide. In August, 2026 GRLNF guidance was cut to $2.48–2.53bn and non-GAAP EPS to $5.15–5.35 (from $5.50–5.70), citing ~$25mm of Q3 Middle East travel disruption and ~$20mm of FX. Plays out if the disruption lasts into 2027 or restaurant and hotel spending slows. Model: rev_growth
- Leverage turns small misses into equity wipeouts. Debt is $4,549mm at face against $773mm of FY2025 EBITDA. Plays out if EBITDA stalls as the 0.90% converts refinance at ~6%. Model: wacc
- Cash earnings are thinner than adjusted earnings. H1 2026 operating cash flow was $197mm against $518mm of adjusted EBITDA, and Q2 adjusted FCF was $21mm. Capitalized spending, including customer-acquisition costs, runs at ~7–8% of revenue. Plays out if "one-time" costs recur and working capital keeps absorbing cash. Model: ebitda_margin, capex_pct_rev, nwc_pct_rev
- The payments sector stays cheap. Fiserv at 6.7x EBITDA shows where the market prices a processor it has stopped trusting. Plays out if the sector's de-rating proves structural. Model: exit_ev_ebitda
Valuation & balance sheet
| Metric (definition) | Current | Own history (range or 5y avg) | Peers | Source, as-of |
|---|---|---|---|---|
| EV/EBITDA, model basis (EV $7,979mm = mkt cap incl. preferred as converted − cash + debt at face + TRA/NCI; GAAP EBITDA after stock comp) | 10.3x FY2025 · ~9.5x H1 2026 annualized (est.) | EBITDA margin on gross revenue 13.6% (FY2023) to 18.5% (FY2025) | Fiserv 6.7x · Global Payments 9.0x · Toast 32.9x (aggregator basis) | model-inputs.json; stockanalysis.com, 2026-09-28 |
| Forward P/E (consensus adjusted EPS) | 6.7x | n/a (unverified) | Fiserv 6.3x · Global Payments 5.9x · Toast 19.8x | stockanalysis.com, 2026-09-28 |
| FCF yield (FY2025 operating cash flow $634mm − capitalized investment ex-CAC $261mm, ÷ Class A market cap) | 12.6% (H1 2026 only $57mm) | n/a | P/FCF: Fiserv 6.3x · Global Payments 27.2x · Toast 30.2x | FY2025 10-K cash flow; Q2 10-Q |
Model-implied value range (from model-summary.json; generic module, Gordon-growth DCF and exit-EV/EBITDA DCF, midpoints): Bear $0.00 · Base $50.31 · Bull $121.54 per share, i.e. implied returns of −100.0% / +34.2% / +224.3% vs $37.48. These ranges show how the bull and bear drivers translate into value; they are not price targets.
- What the price implies. It sits three-quarters of the way from bear to base: a real chance of the bear plateau is priced, not the plateau itself.
- Re-rating. The exit method embeds a de-rating: 8.0x against 10.3x FY0 (−22%). The two methods differ by 12% (Gordon $53.21, exit $47.41). The Gordon method is higher, so it implies a terminal multiple above 8.0x and embeds less de-rating. The Buy holds on the exit method alone (+27%).
- Floored bear. Bear floors at $0 on both methods, but it is not a bankruptcy case: bear FCF stays positive ($23mm Y1, $171mm Y5); 6x on a 16% margin just doesn't cover net debt and other claims. No harsher tail was run.
Balance sheet:
- Net leverage: 5.4x on the model basis (gross 5.9x); the base path falls to 4.4x in Year 1 and 2.3x by Year 5.
- Coverage: EBITDA covers interest 3.1x.
- Liquidity: $356mm of cash at June 30, 2026, plus a $550mm revolver. The July 2026 $1bn term loan add-on pre-funds the converts.
- Nearest material maturity: $633mm of converts, August 2027. Everything else is 2032–2033.
- Ratings: n/a (unverified); company pro forma leverage not re-verified.
Model note: tier full, status built, verification verified (3,207 formula cells matched in LibreOffice). No unverified inputs. No assumptions without basis. Scenario consistency is OK on all 14 rows.
- Sourcing. Historicals from 10-K statements (EDGAR); market, debt and preferred facts from the Q2 2026 10-Q.
- Preferred. 12.74mm shares at the 1.2224 maximum conversion rate (valid below $81.81); remaining dividends excluded.
- WACC. 9.25% = CAPM 8.23% plus a stated 1.0pp leverage premium, because the 5-year beta was measured at lower leverage.
- EPS vs guidance. Base Y1 EPS is $1.16 GAAP, 78% below the $5.15–5.35 non-GAAP guide. The guide excludes acquired-intangible amortization, stock comp and deal costs.
- FCF vs guidance. Base Y1 levered FCF ($234mm) is half the $465–475mm adjusted FCF guide, because the model charges stock comp, deal costs and capitalized customer-acquisition costs.

Notes. Trailing GAAP P/E for Shift4 and Global Payments sits far above their forward P/E on adjusted EPS.
Scenario stress test
Reasoned from the bull/bear drivers above. The model column comes from the scenario overlays (Base case + shock).
| Scenario | Effect | Mechanism | Magnitude | Model Δ value vs Base ($/sh) |
|---|---|---|---|---|
| S1 Fast equity crash | − | Levered, heavily shorted equity de-rates; volumes unaffected | Med | −$13.49 |
| S2 Slow bear / recession | − | Restaurant, hotel and travel spending falls, amplified by operating and financial leverage. Under half of Base − Bear ($50.31) because it lasts two years, while the bear resets growth, margin and multiple permanently | High | −$20.88 |
| S3 Rapid rate shock | − | Floating term loan and refinancing costs rise; a levered equity bears the discount-rate move | High | −$16.09 |
| S4 Slow rate grind | − | Multi-year refinancing drag and a higher discount rate | Low | −$4.91 |
| S5 Soft-landing cuts | + | Lower rates help the levered equity and consumer spending | High | +$17.75 |
| S6 Recession-driven cuts | − | Consumer spending falls faster than rate cuts help | Low | −$5.71 |
| S7a Credit liquidity shock | − | High-yield issuer: spreads gap wider and the equity de-rates; no unfunded maturity before 2032 | High | −$15.47 |
| S7b Slow default cycle | − | Merchant failures raise losses; its own credit spread widens | Med | −$8.87 |
| S8 Stagflation | − | Real discretionary spending and a higher discount rate outweigh nominal volume | Med | −$13.78 |
| S9a Dollar spike | − | Global Blue and European revenue translate lower (FX already cost ~$20mm of 2026 GRLNF) | Low | −$1.67 |
| S9b Dollar slide | + | Mirror of S9a | Low | +$1.67 |
| S10 Melt-up | + | High-beta, heavily shorted equity re-rates with risk appetite | Med | +$10.96 |
| S11 Energy supply shock | − | Middle East travel disruption already cut guidance; oil hits travel spending | Low | −$5.48 |
| S12 Mega-cap/AI derating | − | Fintech multiples de-rate with growth tech | Low | −$3.81 |
Currently active/on watch per the playbook: state.md lists S3 as partially active. The macro log has shown all three S3 legs met since 2026-09-24 (10Y 5.17% on 09-25). S8, S10 and S11 are on watch, and S11 is already visible in Shift4's guidance.
What would change the call
Upgrades if:
- H2 2026 operating cash flow recovers to the FY2025 run rate (~$300mm a half); and
- GAAP EBITDA margin gets back above 18.5% of gross revenue; and
- Organic GRLNF growth holds ≥10%.
Downgrades if:
- 2026 guidance is cut again; or
- GAAP EBITDA margin stays ≤17%; or
- Organic GRLNF growth falls below ~8%; or
- Net debt rises from $4.2bn.
