For decades, earnings per share has been the number investors seek first when evaluating a company. It is simple, widely reported, and easy to compare across quarters and competitors. For pre-retirees in Fresno and Clovis managing portfolios built around long-term wealth, EPS has served as a reliable starting point for understanding whether a business is growing or contracting. That framework still has value. But in a market increasingly shaped by the Magnificent 7, leaning on EPS alone can leave investors with a picture of corporate performance that looks more favorable than the underlying cash economics actually support. Understanding why requires a closer look at how capital expenditures are treated in standard accounting.
The seven largest technology companies, Meta, Amazon, Microsoft, Alphabet, Apple, Nvidia, and Tesla, are spending on AI infrastructure, data centers, custom chips, and cloud capacity at a scale that strains the assumptions built into traditional earnings reporting. Tens of billions in annual investment are going out the door today. The way accounting handles those investments, spreading the cost across years through depreciation rather than recognizing it in the period it is spent, creates a meaningful gap between what EPS reports and what the business is actually deploying. Warren Buffett identified this problem decades ago and developed a different framework for measuring it, one he called owner earnings.
What Owner Earnings Actually Measures
Owner earnings is not a standard accounting term. Buffett introduced the concept in his 1986 letter to Berkshire Hathaway shareholders as a more practical way to answer a fundamental question: how much cash could a business actually distribute to its owners each year after spending whatever is necessary to maintain its competitive position and productive capacity? The calculation starts with reported net income, adds back non-cash charges like depreciation and amortization, and then subtracts the capital expenditures required to sustain the business at its current level. What remains is a more honest representation of the cash the business generates for shareholders, not the earnings the income statement reports.
The contrast with EPS is worth making concrete. EPS is derived from net income, which spreads capital expenditures over time through depreciation. When a company spends one billion dollars on servers today, that cost does not hit the income statement all at once. It is spread across five, seven, or ten years depending on the asset's estimated useful life. EPS in the year of the purchase looks relatively healthy because the full cost has not been recognized. Owner earnings asks what actually left the building. The cash went out the door this year regardless of how the accountants spread it. For companies spending at the scale of the Magnificent 7, this distinction is not a technical footnote. It is a material difference in how economic reality is being measured.
Why Magnificent 7 CapEx Changes the Equation
The Magnificent 7 have collectively committed to levels of capital spending that would have seemed extraordinary even five years ago. Meta announced plans to spend as much as $65 billion in 2025 on AI infrastructure alone. Microsoft, Amazon, and Alphabet have each signaled similar trajectories going forward. The stated rationale is that AI investment is a durable growth opportunity and that returns will justify the outlay over time. That may prove correct. But there is a structural accounting issue worth attention regardless of whether the investments ultimately pay off. The spending is happening now. The depreciation is spread over years. EPS in the near term reflects the schedule, not the actual cash outflow being made today.
This creates a specific risk for investors relying primarily on EPS as a valuation anchor. During periods of heavy reinvestment, EPS can appear stable or growing while the actual cash generation of the business is under meaningful pressure. An investor valuing a Magnificent 7 company based on a reported earnings multiple may be pricing a cash flow stream that looks more favorable on paper than it does in practice. The gap does not mean the company is misrepresenting its results. It means the accounting framework, designed for a different era of capital deployment, is not fully capturing what these businesses must spend year after year simply to maintain the competitive positions they currently hold.
The Maintenance Versus Growth Problem
Buffett's owner earnings framework depends on a distinction that is becoming increasingly difficult to apply to Magnificent 7 companies: separating maintenance capital expenditures from growth capital expenditures. Maintenance CapEx is what a business must spend just to sustain its current earnings power, not to grow, but simply to remain where it is. Growth CapEx is discretionary spending aimed at expanding into new markets or capabilities. In a traditional industrial business, the line between these two categories is relatively clear. Replacing worn equipment is maintenance. Building a new factory is growth. The accounting treatment and the investment implications differ in ways that matter for any serious valuation.
For AI-driven technology companies, that line is much harder to draw. If Microsoft must continue spending heavily on AI infrastructure simply to retain its existing cloud customers and competitive position, that spending is not truly optional. It is closer in nature to maintenance, a cost of staying in the game rather than a bet on future expansion. When spending that looks like growth CapEx on the surface is actually required to sustain existing earnings, the owner earnings calculation changes significantly. The portion of reported net income that genuinely belongs to shareholders is smaller than EPS suggests. For anyone in Fresno or Clovis holding concentrated positions in these companies, understanding this distinction matters in any serious evaluation of what those shares are worth.
Depreciation Assumptions and Future Earnings Risk
There is a second layer to the EPS gap that is less discussed but equally relevant. The depreciation schedules companies apply to technology assets are based on estimates of how long those assets will remain useful. A data center built today might be depreciated over ten to fifteen years. AI chips might carry a five to seven year schedule. Those estimates reflect reasonable assumptions about the pace of technological change. The risk is that AI hardware and infrastructure may become obsolete faster than current depreciation schedules account for. If that happens, companies will face accelerating depreciation charges in future periods, and EPS will come down to reflect costs that were incurred earlier but not yet fully recognized in the income statement.
This is not a prediction that the Magnificent 7 are overvalued or that their AI investments will fail to produce meaningful returns. The point is more specific and practical. Today's EPS figures carry embedded assumptions about how long current assets will remain productive. If those assumptions prove optimistic, future earnings will absorb the difference in ways that are not yet visible in current reports. For pre-retirees in Fresno and Clovis building or managing portfolios with a five to fifteen year retirement horizon, the distinction between what a company earns on paper today and what it is likely to generate in actual cash over time belongs at the center of any thoughtful evaluation of large technology holdings.
What This Means for Long-Term Investors
None of this should be read as a case against owning the Magnificent 7 or maintaining meaningful technology exposure in a well-constructed portfolio. These are genuinely profitable businesses with durable competitive advantages and real pricing power. The concern is not with their profitability but with measurement accuracy during a period of capital spending at historic scale. EPS used alone does not tell the full story when reinvestment is this intense. Owner earnings provides a more complete view of what a business actually generates for shareholders after accounting for what it must spend to stay where it is. In a market where AI investment is accelerating rather than tapering, that distinction is becoming more relevant with each passing quarter.
For long-term investors approaching or already in retirement, technology exposure benefits from looking beyond reported earnings multiples. Understanding the CapEx intensity of a business, the assumptions built into its depreciation schedule, and the degree to which its investment spending is truly discretionary all contribute to a more accurate picture of intrinsic value. At Legacy Finance, we work with clients in Fresno and Clovis to evaluate portfolio holdings through exactly this kind of lens, looking past headline metrics to understand what a company's earnings actually represent and what they are likely to look like over the time horizon that matters for retirement income planning.
Warren Buffett's framework was built for a different era, but its core insight applies directly to the current environment. The more a company must reinvest simply to sustain its competitive position, the smaller the share of its reported earnings that genuinely belongs to the people who own it. In a high-CapEx, AI-driven market, that is not an abstract principle for academic analysis. It is a practical filter for separating businesses that generate durable shareholder value from those that report strong earnings on paper while spending heavily just to remain where they are. For investors with a long time horizon, understanding that difference is one of the more useful things you can bring to a portfolio review.

Frequently Asked Questions
What is owner earnings and how is it different from EPS? Owner earnings is a concept introduced by Warren Buffett to measure how much cash a business can actually distribute to shareholders after spending what is necessary to maintain its operations and competitive position. EPS is an accounting metric based on net income, which spreads capital expenditures over time through depreciation. Owner earnings subtracts the actual maintenance capital spending, giving a more accurate picture of cash generation.
Why do I need to understand CapEx if I own index funds or technology stocks? If your portfolio includes significant exposure to large technology companies, the gap between reported earnings and true cash generation can affect how you assess valuation and long-term return expectations. During periods of heavy reinvestment like the current AI infrastructure buildout, EPS can appear healthy while underlying cash flow is under more pressure. Understanding the difference helps avoid overpaying for earnings that may be temporarily overstated.
Does this mean the Magnificent 7 are bad investments? Not necessarily. These are genuinely profitable businesses with significant competitive advantages. The concern is not profitability but measurement accuracy. EPS alone during a period of intense capital spending does not fully capture what these companies are spending to maintain their positions. A more complete analysis includes CapEx intensity, depreciation assumptions, and whether investment spending is truly discretionary or effectively a cost of staying competitive.
How does this affect retirement portfolio planning in Fresno and Clovis? For pre-retirees and retirees with concentrated technology exposure or significant index fund holdings weighted toward large tech, understanding earnings quality matters alongside traditional valuation metrics. At Legacy Finance, we review portfolio holdings through a lens that goes beyond headline earnings to assess what companies are likely to generate in real cash over the time horizon relevant to your retirement income needs.
What is maintenance CapEx and why does it matter? Maintenance CapEx is the spending a company must make simply to sustain its current level of earnings, as opposed to growth CapEx which funds new expansion. Buffett's owner earnings framework subtracts maintenance CapEx from net income to get a truer picture of distributable cash. For technology companies competing in AI, determining how much of their capital spending is truly optional versus required to retain customers and competitive position is one of the more important and difficult analytical questions in today's market.
