Amcor’s (ASX.AMC) adjusted EBIT of USD 689 million in the quarter ended September 2026 was 3% higher than last year on a constant-currency basis and excluding divestitures. Half-year adjusted EPS guidance, 5% lower at the midpoint than previously guided, reflects the timing of pass-throughs. Shares fell 7%.

Why it matters: We expect costs to pass through gradually through June 2027, weighing on adjusted EBIT margin to 11.3% from 12% in the prior year. Higher costs mostly relate to oil costs since the advent of the Iran war, affecting energy, distribution, and materials, mostly resin.

  • We estimate adjusted EPS of USD 3.80 for the 12 months to June 2027, 5% lower than our prior estimate and the prior year, assuming second-half sales pass through costs and lift margins.
  • Organic volume growth was 1% in the quarter. In niche products, pet food and food service (hospitality take-out items) led 3% volume growth. This aligns with our thesis that niche sales categories will drive sales growth more than the core range, where products may face less competition.

The bottom line: We cut our fair value estimate by 2% to $83/USD 57 per share for narrow-moat Amcor. About half the change reflects lower near-term earnings, and the rest reflects timing impacts on cash flow from holding more and costlier inventory due to supply uncertainty and cost inflation.

  • Shares are cheap. The market overlooks cyclical upside. Some cyclicality reflects a consumer shift to cheaper or bulk products, but long term we expect low-single-digit volume growth aligned with consumption, population growth, and a trend toward convenience and specialty products.
  • We estimate net debt/EBITDA of 3.3 at June 2027, improved from 3.5 in June 2026, against a covenant ceiling of 3.9. We estimate dividends consume about 80% of free cash flow to the firm for the year ended June 2027, but this is temporary due to an inventory build, and we expect it to unwind over the following 12 months.

Higher energy and material costs weigh down Amcor’s operating margins

Amcor’s strategy revolves around strategic acquisitions and divestments, market share growth, and investment in capacity and capabilities. We see several merits to its strategy, which has led to organic and acquisitive growth and average annual returns on invested capital of 9% over the five years to fiscal 2025, including goodwill, comparing favorably against a weighted average cost of capital of 8%.

Amcor strategically acquires and divests assets to drive long-term growth and enhance returns. The most recent was the significant merger of global plastic packaging manufacturer Berry in 2025 for USD 8.4 billion. The merger considerably increased Amcor’s ability to cross-sell Berry’s range to Amcor customers and vice versa, with Berry maintaining a number one or two market share position in most of its markets.

Margin growth is mostly from a mix shift in products. Certain segments, such as animal protein and medical, have higher margins due to greater complexity, tangible benefits, or less competition. However, contracts in the flexibles segment are generally short, at about two to three years, and about 30% are less than one year. We expect incremental margin improvement from higher-value customers as lower-value customers turn over, freeing up manufacturing capacity for higher-value customers. In the five years to fiscal 2023, we estimate average revenue growth from price and mix shift was 4%, compared with 1% growth from volume. Around one fourth of revenue in fiscal 2023 came from the higher-margin segments of healthcare, protein, hot-fill beverages, premium coffee, and pet food from an estimated one fifth five years earlier.

Due to the low value/weight ratio of plastic packaging, it is imperative to reduce the transportation of finished products to control costs. Amcor’s plants are strategically located near customers, particularly in the bulky rigids business. Here, Amcor’s plants are often next door and virtually integrated with the customer’s plant to reduce transportation costs. This encourages stickiness, as these customers sign longer contracts with Amcor and are more likely to renew them on expiration due to the entrenched nature of the partnership.

Bulls say

  • Exposure to high-growth emerging markets balances low-volume growth in mature developed markets for products with similar or higher profit margins.
  • Amcor’s global production network enables improved scale-based cost efficiencies leading to improved margins and profitability and the ability to further consolidate fragmented or subscale markets.
  • A focus on product innovation and differentiation leads to increased market share of niche, high-value-added products, resulting in margin growth.

Bears say

  • Amcor’s aggressive acquisition strategy has the potential for overcapitalization, overcapacity, and lower-than-expected cost synergies.
  • Packaging innovation can be replicated by competitors, decreasing margins, and reducing returns from Amcor’s focus on innovation and product differentiation.
  • Environmental concerns and potential plastics legislation can reduce demand for plastic-based products and increase costs in manufacturing greener alternatives.
