Costco Vs. General Mills: One Is A Premium Worth Paying, The Other Is A Yield Trap

The headline on these two consumer staples companies is not a story about revenue trends. It is a story about two radically different businesses heading in opposite directions, and what happens when you mistake a dividend yield for safety.

Costco is a membership franchise generating 9.2% revenue growth, a record renewal rate, and 23% returns on invested capital. General Mills is a declining packaged-food operator with shrinking revenue, negative return on equity, and a 6.6% dividend yield that is no longer covered by earnings. One commands a premium multiple because the earnings justify it. The other offers a seductive yield to mask the fact that the business is deteriorating faster than most investors are willing to admit.

This is not a comparison of two companies doing similar things at different scales. It is a comparison of a compounding machine and a value trap, masquerading as peers because both happen to sell groceries.

The Costco membership machine

Costco's latest quarter tells the story. In fiscal Q3 2026, total revenue hit $70.5 billion, up 11.5% year-over-year and beating analyst consensus of $69.8 billion. Comparable sales grew 9.8%, with an adjusted comp of 6.6% after stripping out gas price volatility and currency swings. E-commerce comparable sales surged 21.5%, the strongest quarterly e-commerce print in recent memory.

But the metric that matters most is not same-store sales. It's the membership renewal rate, which hit a company record of 93.1% globally. Paid members reached 82.9 million, with 41.2 million holding executive cards — up 9.6% year-over-year, growing more than twice as fast as overall membership.

Why this matters: membership fees generated $1.37 billion in a single quarter, with margins approaching 75–80%. Those fees flow almost directly to the bottom line, unlike merchandise sales which carry inventory risk and thin gross margins of 11%. Costco makes roughly 12.9% on goods it sells, but the membership model is what turns that into $2.2 billion of quarterly net income — a quarterly record.

Cash generation follows the same trajectory. Free cash flow grew 20.4% year-over-year, operating cash flow ran $15 billion on a trailing basis, and the company sits on a net cash position of $14.3 billion. Debt-to-equity is 16.9%. Return on equity is 29.1%.

This is a business where the moat widens every quarter because customers keep renewing, executive memberships are accelerating, and the company is growing same-store sales double-digit while adding 30-plus new warehouses a year. The $420 billion market cap and 47.6x trailing P/E are not cheap. But they are earned.

Costco trades at 1.4x sales and 29.4x EV/EBITDA. For a business growing revenue at 9%, growing FCF at 20%, and generating 23% returns on invested capital, the premium is the price of admission, not a speculation. The next catalyst is the Q3 2026 earnings report on September 24, where consensus expects EPS of $8.51 on revenue of $113.6 billion for the quarter (which would include the holiday quarter roll). That's a high bar, but Costco's track record of beating estimates — it topped EPS in each of the last eight reported quarters — makes the setup familiar.

The General Mills yield trap

General Mills tells a different story. Revenue is declining at 5.5% year-over-year. Free cash flow fell 24.2%. The company generated $1.6 billion of FCF on a trailing basis against $22.6 billion of total debt and a net debt load of $13.1 billion. Debt-to-equity sits at 183.4%. Return on invested capital is 2.1%. Return on equity is negative at -1.1%.

The stock trades at a negative trailing P/E because the company's earnings over the last twelve months were effectively negative. Forward P/E is 8.6x, which looks cheap until you note that analysts project continued earnings decline and the company's guidance for fiscal 2026 called for adjusted EPS to fall 16–20% year-over-year.

On the positive side, General Mills' Q4 fiscal 2026 results reported July 1 showed EPS of $0.95, beating consensus estimates, with revenue of $4.61 billion, up 1.2% year-over-year. CEO Jeff Harmening cited early signs of progress in household penetration and market share. The company cut prices across roughly two-thirds of its North America grocery portfolio to stabilize volumes, and is repositioning products around protein-rich cereals, smaller portions targeting GLP-1 drug users, and premium formats.

But the underlying dynamics are still fragile. Organic net sales are projected to decline 1.5–2% for the full fiscal year. The company is spending heavily on promotions just to hold shelf space against Kraft Heinz, Kellogg, and Nestlé. Q3 fiscal 2026 saw organic sales down 3%, with adjusted EPS of $0.64 missing consensus. The turnaround is real but unproven, and management's own guidance concedes it will take time.

Then there's the dividend. The stock yields 6.6%, which is headline-grabbing. The problem is that the dividend payout ratio is negative on a trailing basis because current earnings do not cover the $2.44-per-share annual payout. The company has paid dividends without interruption for 127 years — a historic record that has become a liability when the business can no longer afford the habit. The dividend is funded by cash flow from operations ($2.2 billion TTM) and by debt, not by profit. That is not a dividend you can treat as safe income.

Valuation reinforces the risk. General Mills trades at 22.7x EV/EBITDA on a declining-earnings base. Compare that to Hershey at 15.4x EV/EBITDA with stable earnings, or even Kellanova, which trades at a fraction of that multiple. The market is paying a stable-food-company multiple for a business whose revenue is contracting, whose ROIC is single-digit, and whose debt load is forcing management to reprioritize every dollar of free cash flow.

What the comparison actually shows

Metric	Costco	General Mills
Revenue growth	+9.2%	-5.5%
FCF growth	+20.4%	-24.2%
ROIC	23.1%	2.1%
Net debt / equity	Net cash $14.3B	Net debt $13.1B
Dividend yield	0.58%	6.61%
EV/EBITDA	29.4x	22.7x
Forward P/E	57.4x	8.6x

The table does not show two similar businesses. It shows a compounding operator with a structural advantage and a declining one offering yield to keep investors from asking harder questions.

The investor takeaway

Costco: Buy on weakness. The stock has declined 6.9% over 120 days and is down 3.6% on a rolling annual basis despite record revenue quarters and membership growth. The premium multiple is justified by membership renewal durability, FCF acceleration, and a capital structure with virtually no downside. The September 24 earnings report is the next proof point — another quarter of mid-to-high-single-digit comps and stable renewal would confirm the growth path can carry the multiple.

General Mills: Hold, not a buy. The 6.6% yield is not a feature; it is a warning sign. Revenue is contracting, the turnaround has not yet shown organic sales improvement, and the debt load constrains management's ability to invest without further leverage. The forward P/E of 8.6x looks cheap only if you ignore the trajectory. A stock that beats one quarter after cutting guidance by 20% is not a turnaround play — it is a relief rally in a declining company. If management can demonstrate organic sales growth for two consecutive quarters and begin reducing net debt, the rating would shift. Until then, the yield is compensation for risk most income investors are not accounting for.

The lesson is not that Costco is a better company. It is that valuation is the bridge between business quality and rating action, and General Mills' yield is doing the heavy lifting that its operating metrics can no longer carry.
