AMZN vs SGI: Which Is the Better Buy in 2026?

Same yardstick, side by side (as of August 2026). Valuation lined up like this is most meaningful for two names in the same corner of the market, which these are. Figures are approximate; verify before investing.

Reading it: SGI is the cheaper of the two on forward earnings, but cheaper is not the same as better. Pair the valuation with growth (how far the forward P/E sits below the trailing P/E) and risk (beta) before you decide.

The metrics above tell you which is the marginally better business. The bigger risk for most people is not picking the slightly worse stock, it is over-concentrating. AMZN and SGI share themes, so owning both, or adding either to what you already hold, can quietly push a large share of your portfolio into one bet.

This is the part a generic comparison page cannot answer, because it depends on what you own. Connect your brokerage and Walnut shows your real, combined AMZN and SGI exposure, flags overlap with your existing positions, and tells you if adding one would tip you past a concentration you are comfortable with, read-only by default, with your login staying at your broker.

Amazon is one of the largest companies in the world, operating across three major business lines. Amazon Web Services (AWS) is the dominant global cloud computing provider, generating around $110 billion in annual revenue and most of the company's operating income. The North America and International e-commerce segments include the Amazon online marketplace, Prime membership, and third-party seller services. Advertising has grown into the third-largest digital ad business in the world (after Google and Meta).

Somnigroup makes and sells beds. The manufacturing side owns Tempur-Pedic, Sealy, Stearns & Foster and Sleepy's, selling into wholesale accounts and consumers across more than 100 countries. The retail side owns Mattress Firm in the United States, Dreams in the United Kingdom, the Sova banner and company-operated Tempur-Pedic stores, a footprint of more than 2,000 US locations. Management reports three segments. Tempur Sealy North America booked $601.8 million of net sales in the second quarter of 2026, down 5.7% year over year, at a 25.9% operating margin. Tempur Sealy International booked $299.5 million, up 2.0%, at 12.4%. Mattress Firm booked $922.2 million, down 2.8%, at 6.4%. The margin spread between those three lines drives almost everything else in the model, because manufacturing earns roughly four times the operating margin retail does, and the acquisition roughly doubled revenue while diluting the consolidated margin. Trailing twelve-month revenue through June 30, 2026 was ~$7.62 billion against ~$4.93 billion in fiscal 2024, the last full year before Mattress Firm consolidated. Total assets rose from ~$5.98 billion at the end of 2024 to ~$11.61 billion, and goodwill from ~$1.07 billion to ~$4.59 billion.

Both fit overlapping themes, but they are not interchangeable. The useful comparison is which set of drivers and risks you want exposure to.

• AMZN drivers: AWS as the AI infrastructure backbone; Retail margin expansion.
• SGI drivers: Vertical integration is doing real work on margin; The all-stock Leggett & Platt acquisition.

A faster-growing, richer-valued name usually swings harder, so it suits a longer horizon and a higher tolerance for volatility; a steadier, more cash-generative business suits a more conservative or income-minded investor. The honest test is which set of risks you could hold through a drawdown: Hyperscaler AI capex is concentrated; if model training demand cools, AWS growth slows. For SGI, leverage is the first-order risk.

Growth-minded investors who believe the theme has years to run tend to accept the richer multiple for more upside; value-minded investors lean toward the cheaper forward earnings and steadier profile. Pick AMZN if you believe its drivers more; SGI if you believe its. Many investors hold both, but since they share themes, that is a concentrated bet, not diversification. Decide deliberately and check overlap. For the full detail, see the AMZN and SGI guides.

AMZN. Amazon's headline P/E reflects the aggregate of low-margin retail and high-margin AWS/advertising. The valuation premium is paid for AWS specifically; retail is essentially valued near cost. P/E of 40x is elevated versus the S&P 500 average (~22x), supported by AWS growth re-accelerating.

SGI. The gap between the ~1.79x price-to-sales multiple and the ~2.61x EV-to-sales multiple is the entire leverage story in two numbers, since ~$6.3 billion of net debt sits between equity value and enterprise value. Another reconciliation matters as much: the company reports 2.99x leverage against ~$4.4 billion of funded debt, implying credit-agreement adjusted EBITDA near ~$1.47 billion, well above the ~$1.27 billion reported figure that enterprise-value screens use. Anyone comparing SGI with an asset-light bedding peer on EV/EBITDA is comparing a company that leases more than 2,000 stores with one that does not.

Headline figures (approximate, early 2026): AMZN shows revenue (ttm) ~$650 billion, operating margin ~10% (AWS materially higher; retail much lower), net income (ttm) ~$60 billion, eps (ttm) ~$5.50; SGI shows revenue (ttm) ~$7.62 billion for the twelve months to June 30, 2026, against ~$7.48 billion in fiscal 2025 and ~$4.93 billion in fiscal 2024. The 51.6% jump in fiscal 2025 is almost entirely the Mattress Firm consolidation from February 5, 2025 rather than organic growth. First-half 2026 net sales of $3,625.0 million were up 4.0% year over year purely because 2026 carries a full six months of Mattress Firm while 2025 carried under five, and the second quarter, the first clean like-for-like comparison, fell 3.0% to $1,823.5 million., earnings and eps Trailing net income of ~$533.3 million on diluted EPS of $2.51, against $384.1 million and $1.84 in fiscal 2025 and $384.3 million and $2.16 in fiscal 2024. Second-quarter 2026 diluted EPS was $0.52 versus $0.47, up 10.6%, with adjusted EPS of $0.58 versus $0.53. First-half net income of $215.1 million against $65.9 million looks explosive only because the prior-year half absorbed acquisition and integration charges. Management guides to $2.85 to $3.15 of adjusted EPS for full-year 2026, roughly 11% growth at the midpoint, cut from an earlier $3.00 to $3.40., segment mix (q2 2026) Mattress Firm $922.2 million of net sales at a 6.4% operating margin, Tempur Sealy North America $601.8 million at 25.9%, Tempur Sealy International $299.5 million at 12.4%. Retail is now ~51% of revenue and a far smaller share of profit. North America adjusted gross margin of 61.8% was up ~680 basis points year over year while International slipped to 47.4% from 48.2% and Mattress Firm's adjusted gross margin fell 240 basis points to 33.3%. The three segments sum exactly to consolidated net sales, so intercompany shipments to Mattress Firm are already eliminated inside the reported segment figures., cash flow and balance sheet First-half 2026 operating cash flow of $482.8 million against $292.5 million a year earlier, capital expenditures of $115.2 million, and trailing free cash flow of ~$769 million. Cash of ~$112 million at June 30, 2026 against ~$6.41 billion of total debt including capitalized store leases, or ~$4.4 billion of funded debt on the company's own reporting basis at 2.99x leverage. Total assets ~$11.61 billion versus ~$5.98 billion at the end of 2024, goodwill ~$4.59 billion versus ~$1.07 billion, total equity ~$3.24 billion, current ratio 0.75 and debt to equity of ~1.98x..

AMZN and SGI are related but distinct: same themes, different businesses and risks. Neither wins in the abstract; the right pick is whichever thesis you actually believe, sized so you are not over-concentrated in one theme. Walnut can show your combined AMZN and SGI exposure against your real portfolio. It is not an investment adviser.
