BALL vs SON: 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: SON 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. BALL and SON 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.

Ball Corporation makes aluminum containers: beverage cans for beer, soda, energy drinks, sparkling water and ready-to-drink cocktails, plus aluminum aerosol and slug packaging for personal care and household products. The business is organized around three regional segments (North and Central America, EMEA, and South America), and it sells into a customer base dominated by a handful of very large beverage companies. Economics are volume-driven and pass-through: aluminum cost is contractually indexed to customers in most contracts, so the swing factor is cans shipped, plant utilization, and the mix between standard and specialty (slim, sleek, tall) formats that carry better pricing. The company completed the sale of Ball Aerospace to BAE Systems for about $5.6B in early 2024, which removed a defense-technology business from the story and left a single-substrate packaging company with a very large pile of proceeds to deploy.

Sonoco Products Company is a global packaging manufacturer founded in 1899 and headquartered in South Carolina. After a multi-year strategic review it has simplified into two reporting segments: Consumer Packaging, which includes rigid paper containers, metal food and aerosol cans, and closures, and Industrial Paper Packaging, which covers the paperboard tubes, cores, and protective packaging that are its historic heritage, plus its industrial plastics business. Sonoco sells to food, consumer-products, and industrial customers around the world, so its results track packaging demand and input costs like recovered paper, energy, and metal rather than any single end product. It is best known among income investors as one of a small group of companies with more than a century of consecutive dividend payments and decades of consecutive annual increases, which puts it in the dividend-aristocrat and dividend-king category.

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

• BALL drivers: Substrate shift toward aluminum; Capital returns as the earnings lever.
• SON drivers: Portfolio simplification into two segments; Eviosys acquisition and metal packaging.

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: Customer concentration is real: a small number of very large beverage companies account for a disproportionate share of volume, which gives them contract leverage at renewal. For SON, the main risks center on the balance sheet and integration: the Eviosys acquisition raised leverage, so a slower-than-planned deleveraging, weaker cash flow, or an interest-rate increase could pressure the balance sheet and the capacity to keep raising the dividend.

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 BALL if you believe its drivers more; SON 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 BALL and SON guides.

BALL. Ball trades around 18x trailing earnings and roughly 12x EV/EBITDA on an enterprise value near $23.9B, a multiple that sits between a defensive staples supplier and a cyclical industrial. FY2025 revenue was about $13.2B with net income near $912M, so the trailing figures reflect a volume recovery rather than a step-change in pricing. Return on equity of roughly 17% is flattered by leverage: return on invested capital is closer to 8.7%, which is the more honest read on how much the underlying can business earns on the capital it deploys.

SON. Figures are approximate and tied to the asOf date; verify live numbers before acting. Sonoco is best understood as a defensive, income-oriented packaging company in the middle of a portfolio transformation, so the near-term story is more about integrating Eviosys and reducing leverage than about rapid earnings growth. Reported results can be noisy during a period of acquisitions and divestitures because of one-time deal, restructuring, and stranded-cost items, so directional trends in segment margins, free cash flow, and net debt matter more than a single headline number.

Headline figures (approximate, August 2026): BALL shows revenue (ttm) ~$14.3B, net income (ttm) ~$947M, eps (ttm) ~$3.53, market cap ~$16.8B; SON shows business One of the world's largest diversified packaging companies, founded in 1899, now organized in two segments: Consumer Packaging and Industrial Paper Packaging, portfolio reshaping Acquired Europe's Eviosys metal-packaging business (approximately $3.8 billion, December 2024); divested TFP to TOPPAN (approximately $1.8 billion) and ThermoSafe to Arsenal Capital (up to $725 million), dividend A core part of the return; more than 100 years of consecutive payments and over 40 consecutive years of increases, a dividend aristocrat and king, recent dividend action Raised the dividend again in 2026, extending the increase streak.

BALL and SON 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.
