F5, Inc. (FFIV)

The methods disagree: one places the value today above the price ($473) and the other below.

Today — expensive, no margin of safety: at $473 trades ~46.1% above its value discounted to today (~$324); the expected return does not even reach the risk-free rate (4.5%).

At 5 years — Sobrevalorado: the expected total return is negative — the price already discounts a demanding scenario that, if not met, results in a loss.

The bridge: the return at 5 years falls below the risk-free rate (4.5%) — which is why there is not even a discount to today's value. To require a 15% annual return, it would need to be bought at ~$201.

The inverse approach: instead of projecting growth to obtain the value, the market price ($473) is taken as given and it solves for what annual owner-earnings growth would need to hold for 10 years for the present value —at the method's rate (4.5%, no-growth terminal)— to equal that price. It is the disconfirmation test: the expectations the price already pays for, contrasted against the method's projection.

The implied growth (5.8%/year) is in line with our base case (7.0%/year) → the price is consistent with the projection.

That growth implies ~$1.3 bn of owner earnings in year 10 (vs ~$1.4 bn of our base case). It recalculates if the DCF assumptions are edited.

Year-by-year projection of the selected scenario. From each year, two versions of the flow are derived: growth FCF (operating flow − total capex, the cash surplus) and maintenance FCF (the owner earnings: what the business yields if it only sustains its capacity). Cash accumulates the retained surplus —what is not returned as dividend or buyback—, so that EV falls and multiples compress going forward. The valuation is done on EV/owner-FCF (flujo de caja libre neto de SBC). In edit mode, revenue, margins, capex, and exit multiples can be adjusted.

Year 0 is the TTM to 30-Jun-2026 (9M FY2026 + FY2025 − 9M FY2025), which already captures the reacceleration in Systems (+31.3% in FY2025, a hardware refresh) and grows 9.4% year over year — in line with the FY2026 guidance raised in the 8-K of 27-Jul-2026 to revenue +9%-10% and non-GAAP EPS US$17.21-17.33. The operating cash margin (ocfMargin) is net of stock-based compensation (25.9% of TTM free cash flow, well above the 7.6% of revenue — the method's TSLA case): without that deduction, the flow would be inflated. Total capex (US$79.8M TTM) is below depreciation and amortization (US$97.4M), so practically all of it is treated as maintenance (maintPct=1) — there is no evidence of material growth capex. The revenue path starts at ~8.5% (the band of the recent trajectory and of the FY2026 guidance) and decays smoothly toward ~5.5% by year 5, the level of a mature compounder but not a business with a hypergrowth runway. Share repurchases are material (~1.6%/year of sustained net reduction since FY2022) and are modeled with an identical sharesPath in all three scenarios (the convention of 16-Aug-2026): the capital return policy does not vary with the speed of the business. With no reported financial debt and more than US$1,600M of cash, the business is debt-free.

Today's elevated multiple is the price of growth: if the business grows, the entry point cheapens on its own going forward (the metric grows while EV stays roughly flat). The exit multiple at 3 years is higher than the terminal at 5 years —at 3 years there is more growth still ahead—, so the value curve shows whether value creation is concentrated in the early or the later years. The required return is applied to the base scenario.

They are valued separately, with their own rationale, and are not incorporated into the base or the verdict (they are excess return). When assigning them value — in Editmode —, the total with optionalities updates live, without moving the base.

The verdict, the base CAGR, and the margin of safety are always calculated on the base; optionalities do not alter them (with optionalities at $0 they do not move).

Each card fixes a required annual return and answers: if the business is worth $404 in 5 years, what is the maximum that can be paid today to obtain that return? Since it now trades at $473, the margin of safety is how much cheaper the market is than that maximum. The three thresholds: 4% covers inflation (the floor), 10% is the long-term average return, and 15% is the level of a great investment.

With a target price of $404 in 5 years and a required return of 4.5% annually, the maximum to pay today is $324. Against the current market price ($473), the margin of safety is -46.1% (trades above the maximum → a premium is paid) and the total return at that price would be -3.1% annually.

• Market multiple above the band. The price implies an owner-FCF multiple well above the mature-software archetype band.
• Improvement already recognized. The strong quarter and raised guidance are already recognized in the price.
• No margin of safety to today's value. The present value of the future flow discounted at the floored risk-free rate falls below the market price.
• Modest base return. The base scenario's compound annual return at market price falls below the 10% bar.

Each margin over sales, year by year: historical (solid line) → projection (dotted).

• ✓ ROIC exceeds the cost of capital (~10%)
• ✓ High incremental ROIC (compounding)
• ✓ CFROIC backs up the ROIC (99%, cash vs. accruals)
• ✓ Healthy balance sheet (low corporate debt)
• ✓ Durable competitive moat (multiple advantages)

• Return on capital. Well above the 10% bar on invested capital from the FY2025 balance sheet; a capital-light business.
• Cash conversion. TTM operating cash flow exceeds net income, though part corresponds to stock-based compensation expensed in the valuation metric.
• Material stock-based compensation. Equal to 25.9% of TTM free cash flow (7.6% of revenue); the valuation metric explicitly nets it out.
• Low capex. Total TTM capex is below depreciation and amortization, consistent with capex being almost entirely maintenance.

Annual levels from the official filing (10-K); the % over each bar is the year-over-year (YoY) growth vs the prior year.

F5's historical data only provides two-year granularity (FY2024/FY2025) for the Systems/Software breakdown; there is no four-year series as for other drivers under the method. The split was verified by exact cross-foot against total consolidated revenue in both fiscal years, so it is used with confidence despite the discrepancy flagged in the multi-pass extraction. Deferred revenue gives an advance signal of subscription demand, though F5 does not report an explicit RPO comparable to that of pure SaaS businesses.

The % are the annual (year-over-year) growth: each year —historical and projected— vs the prior one; the TTM (trailing 12m) vs the TTM of a year ago, to avoid overlapping windows. The historicals are exact figures from the official filings; the projected years come from the year-by-year model (the intermediate years without their own series are interpolated between the anchors). The projected columns (+1y…+5y) are 12-month windows counted from the TTM close (30-jun-2026): the projection starts from the most recently reported data, not the fiscal year. The projected base is realistic and unbiased — the risk discount is applied at the end, via the required return. The rationale for each metric is in the (i).

• Systems rebound. BIG-IP hardware grew 31.3% in FY2025, more akin to a renewal cycle than structural growth.
• Subscription software. Software grew 9.2% in FY2025, with the mix shifting toward subscription and SaaS.
• Raised FY2026 guidance. The company raised revenue guidance to 9%-10% and non-GAAP EPS guidance to $17.21-17.33.
• Services barely grow. Services, the largest line, grew just 2.3% in FY2025.

• Diversified business model. Hardware, subscription/SaaS/perpetual software, and services across the same enterprise customer base.
• Dependence on two distributors. Two global distributors account for 33.3% of FY2025 net revenue.
• Sales cycle concentrated at quarter-end. A substantial portion of orders close in the final weeks of the fiscal quarter.
• Manufacturing outsourced to a single supplier. Hardware assembly depends on a single contract manufacturer (Flex), in Mexico and China.
• Multiple competitive fronts by line. Each product line (BIG-IP, NGINX, security) faces a distinct and active competitive set.

A traffic-light interpreted by the method (not generic): float (negative WC) adds up, capex is judged by incremental ROIC (malinvestment test), and a lender is not subjected to corporate solvency. The (i) shows the derivation of each number.

• No financial debt. The balance sheet's long-term and short-term debt tags show no outstanding balances.
• Abundant cash. More than $1,600 million in cash and equivalents at the close of the third fiscal quarter of 2026.
• Buyback funded with internal cash flow. Share buybacks are financed with operating cash flow, not debt.
• Recent cybersecurity incident. One-time costs of ~$26.5 million in 9M FY2026, with partial insurance recovery.

Who owns the shares — the alignment and whether there is a controlling shareholder.

• Long-tenured CEO. François Locoh-Donou has led F5 since 2017, with prior experience as COO of Ciena.
• Low executive ownership. Individual ownership by directors and executives is low relative to total shares outstanding.
• Capital allocation via buybacks. Cash use is concentrated in share buybacks (~$626 million TTM) with no dividend payments.
• Complementary acquisition. The 2025 acquisition of CalypsoAI adds AI inference security, of limited size.

• No clear identifiable source of missing buyers or motivated sellers.
• Raised FY2026 guidance and the Systems rebound sustain market enthusiasm in the short term.
• The October 2025 cybersecurity incident does not appear to have materially hit the stock price.

No clear source of discount is identified (§3 Step 9): there is no recent spin-off, no absent analyst coverage, no cycle bottom, and no one-off masking real value. The strong quarter and raised guidance are already known to the market. With no identifiable missing buyers or motivated sellers, the correct reading is that the stock is not cheap: it trades at a multiple that already discounts the continuation of the Systems rebound and the execution of FY2026 guidance.

The annual return (CAGR at 5 years) in each scenario, with the total period return below — the margin of safety made visual: upside range wide, downside range narrow.

Even in the bear scenario, the return holds at -16%/year (-57% total): the margin of safety protects the downside. The bull (+2%/year, +13% total) exceeds it comfortably — a favorable asymmetry, with a narrow downside range and a wide upside range.

• Cybersecurity incident with reputational impact. A threat actor maintained persistent access to F5 systems; risk of litigation and higher insurance costs.
• Concentration in two distributors. 33.3% of FY2025 net revenue flows through two global distributors.
• Pricing pressure and competitive consolidation. Competitors combining hardware and software into integrated offerings could compress average selling price.
• Hardware renewal cycle is cyclical. The Systems jump in FY2025 may not repeat; a slowdown there hits consolidated revenue directly.

Each thinker's analytical framework applied to our data.

• Buffett / Graham Quality + margin of safety

  A narrow moat and ROIC 31% above the 10% bar, but the price sits above value (no margin) → great business, expensive.

• Peter Lynch Growth at a reasonable price (GARP)

  A stalwart growing 7% at a multiple/growth of 5.1 → expensive for its growth.

• Joel Greenblatt Cheap and high-return (Magic Formula)

  Earnings yield 3% (EBIT/EV) + ROIC 31% → falls outside the Magic Formula.

• Howard Marks Perception vs reality + cycle

  The price discounts 6%, in line with our 7%: perception and reality aligned.

• Seth Klarman Capital protection (bear scenario)

  Bear-scenario floor -16%/yr over 5y (material loss) → risk of permanent capital loss.

• Pat Dorsey Moat strength (Five Rules)

  A narrow moat, stable; sources: switching costs, intangibles, network effects, efficient scale → partially passes the Five Rules.

• Aswath Damodaran Expectations implied by the price

  Justifying the price requires discounting 6%, within what we project (7%) — the story squares with the numbers.
