Apple vs Microsoft: Which Trillion-Dollar Compounder Wins the Next Five Years?

Apple's FY2025 revenue reached $416.2 billion, up 6.4% from $391.0 billion in FY2024. Net income climbed to $112.0 billion from $93.7 billion, a 19.5% pace, lifted by an effective tax rate normalisation and operating margin expansion to 35.4% from 31.5%. Free cash flow ran at $98.8 billion against $108.8 billion in FY2024. The cash flow line declined modestly as working capital and tax timing absorbed some of the operating cash strength.

The Apple revenue mix in FY2025 was approximately 53% iPhone, 8% Mac, 6% iPad, 8% Wearables-Home-and-Accessories, and 25% Services. The Services segment continued to compound in the low-to-mid teens, contributing roughly $103 billion to the FY2025 revenue line. iPhone revenue grew at low single digits as upgrade cycles lengthened in mature markets, partially offset by the AI-feature-driven refresh cycle that helped FY2025 numbers in the second half of the fiscal year.

Apple's capital allocation in FY2025 deployed approximately $112 billion to buyback and dividend combined, against $98.8 billion of FCF. The shortfall was funded by net cash drawdown and modest incremental debt issuance. The framework is generous to shareholders but is no longer self-funding at the FY2025 cash flow run-rate. That dynamic is new and represents a structural shift from the prior decade.

The forward PE of 31.3x is built on FY2026 EPS consensus of approximately $8.25 against a stock price of $258. The trailing PE is 33.9x. Both multiples are at or near 10-year highs for Apple. The premium is driven primarily by the AI-narrative re-rating that began in mid-2024 and the services-segment durability story that has been steady through cyclical macro uncertainty.

Microsoft's FY2025 revenue reached $281.7 billion, up 14.9% from $245.1 billion in FY2024. Net income climbed to $101.8 billion from $88.1 billion, a 15.6% pace. Free cash flow ran at $71.6 billion against $74.1 billion in FY2024 (the FY2024 figure benefited from working capital timing). Operating margin sat at 47.1%, comfortably the highest level in the company's modern history.

The Microsoft revenue mix in FY2025 was approximately 47% Intelligent Cloud (driven by Azure), 32% Productivity-and-Business-Processes (Office 365, Dynamics, LinkedIn), and 21% More Personal Computing (Windows, Xbox, Surface, Search). Azure revenue compounded at approximately 33% in FY2025, contributing the large majority of the consolidated growth rate. Co-Pilot and the broader AI-augmentation product set added a measurable revenue lift across the productivity segment.

Microsoft's capital allocation deployed approximately $48 billion to buyback and dividend combined in FY2025, with the residual cash flow funding capex and the remaining cash position. Capex ran at approximately $50 billion in FY2025, driven by Azure capacity buildout. The capex cycle is intense but is fully self-funded by operating cash, with the buyback continuing alongside.

The forward PE of 22.1x is computed against FY2026 consensus EPS of approximately $19.20 against a stock price of $425. The trailing PE is 26.6x. Both multiples are below the 5-year average and well below the 2021 peak. The compression reflects cyclical sentiment on the broader software sector and concerns about AI capex returns; both have softened the multiple even as the operational performance has accelerated.

Run AAPL and MSFT through five structural dimensions. Revenue growth: MSFT at 14.9% versus AAPL at 6.4%. The 8.5 percentage point gap is the widest in the last decade. Microsoft's growth advantage is not a one-quarter aberration; it has held for six consecutive quarters and shows no sign of compressing.

Operating margin: MSFT at 47.1% versus AAPL at 35.4%. Microsoft's margin profile is structurally higher because of the software-and-cloud mix versus Apple's hardware-heavy mix. The margin gap will not close because the underlying business mix does not allow it. Microsoft's margin trajectory is also still expanding, while Apple's has more or less plateaued near the 35% range.

Free cash flow growth: MSFT FCF compounded at 6.3% over five years (working capital timing makes the year-on-year comparison noisy), while AAPL's FCF has been roughly flat over the same window. Both produce massive absolute cash flow, but Microsoft's is growing and Apple's is not.

Capital allocation efficiency: Both buyback aggressively. Apple's buyback at $115 billion annual pace is a larger absolute number, but is no longer self-funded at FY2025 FCF levels. Microsoft's smaller buyback is fully self-funded with cushion. The dividend policy is also different: Microsoft grows the dividend at high single digits annually, Apple at modest single digits. Both are shareholder-friendly, but Microsoft's framework has more financial cushion.

Competitive moat depth: Both have unassailable franchise moats. Apple's iPhone-Services flywheel is the largest single consumer-tech moat in the world. Microsoft's enterprise software-and-cloud combination is similarly dominant within the corporate-IT category. The Research Desk view is that both moats are structurally strong, but Microsoft's enterprise-cloud tailwind has more multi-year compounding runway than Apple's iPhone-Services dynamic at current saturation levels.

Four of five favour Microsoft. The single dimension favouring Apple (absolute buyback scale) does not justify the multiple premium. The verdict is direct: Microsoft is the better risk-adjusted long position at today's relative pricing.

Both companies have been re-rated by the AI narrative since 2023, but the operational evidence has played out very differently for each. Microsoft's AI exposure is concrete. The Co-Pilot product line is generating revenue (approximately $5-7 billion annualised by end of FY2026 on disclosed metrics), Azure OpenAI consumption is contributing to the Azure growth rate, and the embedded AI-feature suite within Office 365 is justifying the price increase taken in FY2025. The AI narrative for Microsoft is showing up in the income statement.

Apple's AI exposure is largely prospective. Apple Intelligence, the framework launched alongside the FY2024 iPhone refresh, has driven incremental upgrade activity but has not produced disclosed revenue line uplifts comparable to Microsoft's Co-Pilot. The bull case is that Apple's services revenue inflects upward as Apple Intelligence and the broader AI-feature roadmap unlock new services categories. That bull case has not yet materialised in the disclosed numbers. The most recent fiscal-year services growth rate sat at roughly 12-13%, similar to the pre-AI-narrative trajectory.

The AI re-rating has therefore lifted both multiples, but only Microsoft has the operational underpinning to justify the multiple at current levels. Apple's multiple is paying for an AI-services inflection that has not yet shown up in the data. That is the cleanest single difference between the two and the largest source of the relative-value gap.

If the Apple Intelligence services inflection materialises in FY2027-FY2028, the multiple is supported. If it does not, Apple's multiple compresses 4-6 turns to roughly 25x, which would imply a $200 share price. The asymmetry from $258 is unfavourable. Microsoft has the opposite asymmetry: if AI tailwinds compress, the multiple holds at 22x because the core enterprise franchise still compounds; if AI tailwinds extend, the multiple expands to 26-28x with FCF acceleration. The Research Desk prefers the latter setup.

Free cash flow per dollar of revenue is the cleanest single metric for franchise quality. Apple converts roughly $0.24 of every revenue dollar to free cash flow. Microsoft converts roughly $0.25. The headline ratio is similar, which is partly why investors have historically treated the two as substitutes. The trajectory of those ratios tells a different story.

Apple's FCF-to-revenue ratio has compressed from 0.31 in FY2022 to 0.24 in FY2025 as the iPhone-upgrade cycle lengthened and the Services contribution settled into a steady-state pace. Microsoft's same ratio has held in the 0.24-0.30 range throughout the period, with the FY2024-FY2025 compression entirely explained by the elevated Azure capex (which depresses FCF in the build phase but is value-accretive over the asset life). Apple's FCF compression is structural; Microsoft's is cyclical.

FCF per share growth tells a similar story. Apple's FCF per share grew at 4% over the trailing five years, supported almost entirely by the buyback rather than absolute FCF growth. Microsoft's FCF per share grew at 12% over the same window, with both absolute FCF growth and buyback contributing. The compounding gap is not subtle.

Return on invested capital sits at approximately 38% for Microsoft and 30% for Apple. Both are exceptional, but the gap reflects the same underlying mix differences as the operating margin discussion. Microsoft's higher software-and-cloud mix produces structurally higher returns on invested capital, and that gap is widening rather than closing as the cloud capacity that has been built begins delivering revenue at scale.

Apple's customer-mix risk is heavily concentrated in two regions. Greater China contributes approximately 15-17% of revenue and is exposed to consumer-spending cyclicality, FX volatility, and the broader US-China commercial-policy backdrop. The China revenue trajectory has compressed for three consecutive years, with FY2025 coming in roughly 8% below the FY2022 peak. Apple's product-cycle dependency on Chinese consumer demand is a real tail risk; the 2024-2025 weakness has only been partially offset by India and southeast Asia growth.

Microsoft's customer-mix risk is concentrated in enterprise IT spending. Approximately 75% of revenue comes from corporate customers under contractual subscription frameworks. The recurring-revenue character of those contracts insulates the FY2026 outlook from short-term consumer cyclicality. The risk is concentrated in enterprise IT-budget compression scenarios, which have been a consistent concern of bears for two years and which have not yet materialised in the operational data.

The geographic concentration favours Microsoft. The US contributes roughly 50% of Microsoft's revenue, with Europe at 25% and rest-of-world at 25%. The mix is more balanced than Apple's, with no single region carrying the same single-product-cycle risk that Apple's China exposure carries. The structural risk profile is meaningfully cleaner.

Net of the geographic and customer-mix overlay, the Microsoft setup looks structurally more durable. That is a statement about FY2026-FY2028 visibility, not about absolute franchise quality. Apple remains a world-class franchise, but the multi-year visibility into the cash flow line is meaningfully harder to underwrite at today's price.
