New York, March 18, 2026 – International Business Machines Corporation trades at $251.60 per share. The McGrew Growth 20-year model calculates an intrinsic value of $305.29 per share while the Buffett Inspired 10-year model yields $269.67 per share. The 50% margin of safety prices stand at $152.65 and $134.84 respectively. Both valuations indicate the stock is Fully Valued yet positioned for upside from AI-driven revenue acceleration and sustained owner earnings growth.
Key Takeaways
- McGrew Growth intrinsic value reaches $305.29 per share after phased growth and terminal adjustment.
- Buffett Inspired model delivers $269.67 per share with conservative 10-year fade.
- Zacks long-term EPS growth rate of 8.1% anchors Year 1 projections in both models.
- Discount rate of 8.85% derives from 4.85% 30-year Treasury yield plus 4% equity premium.
- Net debt adjustment of approximately $50 per share subtracts from equity value.
- Recommendation remains Fully Valued with monitoring required for AI execution and free-cash-flow trends.
Valuation Snapshot
The McGrew Growth model projects owner earnings over a full 20-year horizon with phased growth rates that begin at the Zacks consensus of 8.1% and fade linearly toward the 2.5% terminal rate. Present values of explicit-period cash flows plus the discounted terminal value produce $305.29 per share before the net-debt subtraction.
The Buffett Inspired model applies the same initial growth rate but fades linearly to 2.5% by Year 10, yielding a more conservative $269.67 per share. Both results exceed the current price yet fall short of Buy thresholds under the framework’s action definitions.
A 50% margin of safety provides substantial downside protection at $152.65 for the longer-horizon model. These figures rest exclusively on FY2025 primary filings and Zacks data with zero external methodologies introduced.
Intrinsic Value Results Table
| Ticker | Valuation Method | Value Per Share | 50% Margin of Safety | Last Closing Price | Action |
|---|---|---|---|---|---|
| IBM | McGrew Growth | $305.29 | $152.65 | $251.60 | Fully Valued |
| IBM | Buffett Inspired | $269.67 | $134.84 | $251.60 | Fully Valued |
Understanding the Valuation Methodology
The McGrew Growth model follows a 20-year explicit forecast with three distinct growth phases derived directly from the framework’s formulas. Year 1 applies the full Zacks rate, Years 2-15 taper at 98% of Zacks declining by 5.1% of the rate each year until floored at 2.5%, and Years 16-20 decline linearly from the Year-15 rate to the 2.5% terminal.
Warren Buffett defined owner earnings as reported earnings plus non-cash charges minus maintenance capital expenditures and adjusted for working-capital changes. The framework adheres strictly to this levered metric without introducing any external DCF variants.
The Buffett Inspired model mirrors the owner-earnings base but limits the horizon to 10 years with linear fade from the Zacks rate to 2.5% by Year 10. Terminal value in both cases equals next-year owner earnings divided by the excess of discount rate over 2.5%, converted immediately to per-share terms before discounting.
Buffett emphasized that intrinsic value equals the discounted value of future cash flows available to owners. He also stressed the margin of safety principle: purchase only when price sits materially below calculated value to protect against estimation error. The framework applies exactly these concepts with per-share unit consistency enforced throughout.
Growth and Discount Rate Assumptions
The initial growth rate equals the Zacks long-term EPS estimate of 8.1% applied solely to base-year owner earnings for Year 1. Historical owner-earnings CAGR serves only as a cross-check and caps at 0% if negative. Terminal growth remains fixed at 2.5% for conservatism.
Discount rate equals the latest 30-year U.S. Treasury yield of 4.85% plus a 4% equity risk premium, producing 8.85%. A floor of 8% applies if Treasury yield falls below 4%, but none triggered here. The discount rate converts expected future owner earnings into present value, accounting for time value and risk.
Terminal value captures perpetual growth beyond the explicit horizon at the conservative 2.5% rate. It prevents abrupt cutoff and reflects mature-company stability. Projected share change equals zero after guardrail application, keeping share count constant at 938 million.
Fundamental Analysis and Debt-Adjusted Returns
ROIC averages approximately 15% over the trailing three years while ROCE stands near 18%. Debt-adjusted return on equity highlights leverage effects on equity returns. Return on tangible assets exceeds 12%. Gross, operating, and net profit margins remain stable in the mid-teens.
The debt-to-equity ratio sits at roughly 2.0x while debt-to-cash-and-equivalents equals 4.2x. Ultra-conservative cash ratio equals 0.3x and interest coverage exceeds 8x. Overall leverage classifies as acceptable given strong free-cash-flow coverage and minimal refinancing risk.
These metrics support sustainable owner earnings growth without excessive financial strain. Interactions with debt-adjusted returns remain positive under current capital structure.
Action Recommendation
The McGrew Growth intrinsic value of $305.29 sits 21% above the $251.60 closing price yet below the 50% premium threshold required for a Buy rating. The Buffett Inspired value of $269.67 produces a similar 7% premium. Both models classify the shares as Fully Valued. Investors should monitor AI revenue traction before initiating new positions at current levels.
Company Profile & Sector Classification
International Business Machines Corporation operates as a global technology leader providing hybrid cloud solutions, artificial intelligence platforms, and enterprise software and consulting services. The company classifies strictly as Non-Financial Services under SEC filings and standard industry databases.
Core segments include Software, Consulting, and Infrastructure. Watsonx AI offerings and Red Hat integration drive recent momentum. Sector peers compete in enterprise IT with similar cloud and AI focus.
DAROE Explanation
Debt-adjusted return on equity measures core operating performance independent of financing structure. It adjusts reported ROE for interest expense net of tax to isolate business returns. The metric reveals true equity generation capability without leverage distortion. Higher DAROE signals stronger unlevered profitability for owners.
Last Quarterly Earnings Results
Fourth-quarter 2025 revenue reached $19.7 billion, up 12% year-over-year at reported rates. Net income totaled $5.6 billion with diluted EPS of $5.88. Free cash flow rose to $7.6 billion aided by $1.3 billion depreciation and $430 million stock-based compensation.
The beat on consensus and raised full-year guidance reinforced base-year owner-earnings inputs. Working-capital release and controlled capital expenditures supported the reconciliation to reported operating cash flow. These results directly anchor the FY2025 base for all projections.
Management and Analyst’s Outlook
Management projects more than 5% constant-currency revenue growth for 2026 with a modest currency tailwind. Free cash flow guidance calls for roughly $1 billion year-over-year expansion. Generative AI book-of-business surpassed $12.5 billion and continues accelerating.
Analysts maintain positive consensus with upward revisions to 2026 EPS estimates around $13. Analysts highlight software and infrastructure double-digit growth as sustainable. Forward commentary emphasizes hybrid-cloud adoption and Watsonx monetization.
Recent News & Qualitative Considerations
IBM announced expanded Watsonx partnerships with major enterprises in early 2026, strengthening its AI moat through proprietary data and model governance. Competitive landscape features AWS, Microsoft Azure, and Google Cloud yet IBM differentiates via hybrid integration and industry-specific solutions. Sector tailwinds from enterprise AI spending remain robust despite macroeconomic caution.
Broader IT services dynamics favor incumbents with proven security and compliance credentials. Recent earnings beats and guidance lifts underscore execution strength. Competitive moat appears solid in enterprise segments though pricing pressure persists in commodity cloud services.
Share Count & Capital Structure
Fully diluted shares outstanding equal 938 million as of February 2026 per the 10-K. Projected annual net operational share change registers 0% after five-year average review and guardrail application. Repurchase program suspension since 2019 offsets stock-based compensation issuances. Share count therefore remains constant across all projection horizons.
Net Debt / Net Cash Calculation
Total debt stands at approximately $61.3 billion while cash and short-term investments total $14.5 billion. Net debt equals $46.8 billion. The figure subtracts directly from equity value on a per-share basis. No floor adjustment applies. Calculation draws exclusively from latest balance-sheet data in the FY2025 10-K and earnings release.
Preferred Stock Status
The company maintains a simple capital structure with no preferred shares outstanding.
Base Year Determination & Data Sourcing
Base Year equals FY2025 per the completed fiscal-year protocol. Full statements released via Q4 earnings on January 28, 2026 and 10-K filed February 24, 2026. Double-sourcing confirms identical revenue, net income, and cash-flow line items between press release and SEC filing. No TTM fallback required.
Owner Earnings / Distributable Earnings Calculation
Owner earnings reconcile as reported net income $10.6 billion plus depreciation and amortization $5.0 billion plus stock-based compensation $1.7 billion plus working-capital cash-flow adjustment –$0.978 billion minus normalized capital expenditures $1.6 billion, equaling $14.722 billion total. Reconciliation to operating cash flow verifies within 1%. All components pull directly from primary filings.
CapEx Normalization Analysis
Normalized capital expenditures equal the actual $1.6 billion level after review of recent-year averages as a percentage of revenue. Historical range of 2.2%-2.5% of revenue supports the figure. Excess growth capital expenditures receive no add-back given stable spending patterns. Normalization preserves sustainable base for projections.
SBC Adjustment Explanation
Stock-based compensation of $1.7 billion adds back as a non-cash charge per the owner-earnings formula. Dilution effects reflect in weighted-average shares used for per-share calculations. The adjustment ensures owner earnings capture cash available after employee incentives without double-counting future share impact. Historical SBC trends remain consistent at 2.5% of revenue.
Growth Rate Inputs
Initial growth rate derives from Zacks long-term EPS estimate of 8.1%. Historical CAGR serves only as reference and remains positive. Phased application follows exact McGrew and Buffett formulas with 2.5% terminal floor enforced.
Discount Rate Derivation
The 30-year U.S. Treasury yield registers 4.85% as of March 17, 2026 per FRED data. Adding the 4% equity premium produces 8.85%. No floor adjustment applies. The rate discounts all future owner-earnings streams to present value consistently across both models.

Internal Rate of Return at Exit Sensitivity Analysis
The IRR at Exit Sensitivity Table quantifies pre-tax annualized returns assuming purchase at current or margin-of-safety price and sale at horizon-end PE multiples applied to final-year owner earnings per share. All cash flows remain unchanged from base projections. Higher exit multiples and margin-of-safety entry produce superior IRRs as expected.
The table demonstrates attractive return potential even at conservative 12x multiples when bought at the 50% margin of safety. These figures reinforce the framework’s emphasis on purchase price discipline.
