IP vs PKG: Which Is the Better Buy in 2026?
Last updated August 2026
Short answer
IP and PKG are similarly sized, but IP trades noticeably cheaper on forward earnings (13.89x vs 19.39x): the market is paying up for PKG's profile and pricing IP more conservatively, or for faster growth. Which you prefer comes down to the drivers you believe, and whether adding either over-concentrates what you already own.
IP vs PKG: the tie-breaker metrics
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.
| Metric | IP | PKG | What it tells you |
|---|---|---|---|
| Forward P/E | 13.89 | 19.39 | Valuation on next year's expected earnings, the same yardstick for both. Lower is cheaper for that growth; higher means the market is paying up. |
| Beta | 0.90 | 0.82 | Volatility vs the market. Above 1 swings harder than the index; below 1 is steadier. Higher beta means bigger drawdowns to hold through. |
| Price vs 52-week range | 55% of range | 81% of range | Where today's price sits between the 52-week low and high. Near the high is momentum with less margin of safety; near the low is out of favor or a discount, depending on why. |
| Price / book | 1.46 | 4.74 | How much you pay over book value. Very high can signal an asset-light, high-return business or a rich price. |
Reading it: IP 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.
Before you buy: how IP and PKG affect your concentration
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. IP and PKG 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 IP and PKG 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.

What does International Paper (IP) do?
International Paper is a leading global producer of fiber-based packaging, pulp, and related products, best known for corrugated containers and the containerboard that goes into them. Its boxes carry everything from food and beverages to e-commerce shipments and industrial goods, so demand broadly tracks consumer and industrial activity. The company sells mainly to businesses rather than consumers, and its economics turn on containerboard pricing, box volumes, input costs like fiber and energy, and mill utilization. As a large, capital-intensive manufacturer, it competes on cost, scale, and its distribution and converting network.
What does Packaging Corporation of America (PKG) do?
Packaging Corporation of America makes containerboard and the corrugated boxes and displays that carry most physical goods, plus a smaller Paper segment producing uncoated freesheet (office and printing papers). It runs a highly integrated network of mills and box plants, which lets it convert most of the containerboard it makes into finished packaging for food, beverage, e-commerce, and industrial customers. That vertical integration and a low-cost mill base are the core of its reputation for consistent margins in a commodity-exposed industry.
IP vs PKG: how do they differ?
Both fit overlapping themes, but they are not interchangeable. The useful comparison is which set of drivers and risks you want exposure to.
- IP drivers: DS Smith integration and global scale; Cost cuts and footprint optimization.
- PKG drivers: Volume share gains; Price realization catching up to costs.
Which fits which kind of investor
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: The main risk is cyclicality: box volumes and containerboard pricing move with consumer and industrial activity, so an economic slowdown can reduce demand and pressure pricing and margins, as recent low-single-digit volume softness showed. For PKG, pKG is cyclical and tied to the goods economy, so a slowdown in shipping and box demand can cut volumes and pricing at the same time.
IP or PKG: which should you pick?
IP vs PKG: the full fundamentals
IP. Figures are approximate and tied to the asOf date; verify live numbers before acting. Packaging producers like International Paper are cyclical, so trailing earnings can be distorted by restructuring charges and where box volumes and containerboard prices sit in the cycle. That makes forward margins, synergy capture, and the value the market assigns to the two separated companies more important to the thesis than a single point-in-time earnings multiple.
PKG. PKG trades at a mid-to-high 20s trailing earnings multiple, a premium to some packaging peers that reflects its integration and margin consistency. Q1 2026 net sales rose to about $2.4 billion from $2.1 billion a year earlier on double-digit volume growth, though EPS came in below some estimates as input and maintenance costs weighed on margins. The valuation and dividend framing here are approximate and change with the market.
Headline figures (approximate, Jul 2026): IP shows transformation Completed DS Smith acquisition (Jan 2025); planned geographic split announced early 2026, synergy target At least several hundred million dollars from the DS Smith combination, 2025 segment strength North American packaging adjusted EBITDA grew sharply with margin expansion, 2026 earnings Expected to absorb substantial restructuring charges from footprint actions; PKG shows market cap ~$19 billion, revenue (ttm) ~$9 billion, q1 2026 net sales ~$2.4 billion, q1 2026 eps (ex-items) ~$2.40.
The bottom line: IP vs PKG
IP and PKG 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 IP and PKG exposure against your real portfolio. It is not an investment adviser.

FAQ
What is the difference between IP and PKG?
+
International Paper is a leading global producer of fiber-based packaging, pulp, and related products, best known for corrugated containers and the containerboard that goes into them. Packaging Corporation of America makes containerboard and the corrugated boxes and displays that carry most physical goods, plus a smaller Paper segment producing uncoated freesheet (office and printing papers). They show up together because they share investment themes, but they are different businesses, so the better fit depends on which thesis you are expressing.
Is IP or PKG the better stock?
+
Neither is universally better; they suit different views and risk levels. Walnut is informational, not investment advice. Compare what each does, the tie-breaker metrics above, and the risks, then decide which fits your thesis and what you already own.
Which is cheaper, IP or PKG?
+
On forward P/E (as of August 2026), IP trades at 13.89x and PKG at 19.39x, so IP is the cheaper of the two on next year's expected earnings. A lower multiple is not automatically the better buy: a richer valuation can be justified by faster growth, and a lower one can reflect real risk. Weigh the multiple against how fast each business is compounding.
Should you own both IP and PKG?
+
Because they share themes, owning both concentrates you in that theme. That can be intentional (a focused bet) or accidental (less diversification than it looks). Walnut can show your combined exposure across both, and whether adding either over-concentrates you, before you buy.
What are the risks of IP vs PKG?
+
IP: The main risk is cyclicality: box volumes and containerboard pricing move with consumer and industrial activity, so an economic slowdown can reduce demand and pressure pricing and margins, as recent low-single-digit volume softness showed. The transformation adds substantial execution risk: integrating DS Smith, capturing synergies, and separating into two companies all carry costs, distraction, and the possibility of dis-synergies or delays. Heavy restructuring charges are expected to weigh on 2026 earnings even as they set up future savings. Input costs for fiber, energy, and chemicals are volatile and can compress margins. The business is capital intensive and carries debt increased by the DS Smith deal, so higher rates raise financing costs. Trade policy, tariffs, and currency swings add further uncertainty across its now larger international footprint. PKG: PKG is cyclical and tied to the goods economy, so a slowdown in shipping and box demand can cut volumes and pricing at the same time. Containerboard is partly a commodity, meaning industry capacity additions or price declines can squeeze margins the company cannot fully control. Input costs (fiber, energy, freight, chemicals) and heavy scheduled maintenance can pressure earnings even in decent demand periods, as seen when operating margin fell to about 10.7% from 13.1% year over year. The Paper segment faces structural decline in office-paper demand. Finally, as a single-industry manufacturer, PKG lacks the diversification of a broader materials or industrials holding.
