Amcor (NYSE:AMCR) has changed its external auditor, with PricewaterhouseCoopers AG in Switzerland resigning and PricewaterhouseCoopers LLP in the United States taking over. This change reflects the company’s US reporting status and its growing US operations.

For investors tracking Amcor, the recent auditor change lands against a backdrop of solid share price momentum. The stock has delivered a 20.13% 90 day share price return and a 17.68% 1 year total shareholder return, while the 5 year total shareholder return is slightly negative and signals that longer term performance has been more mixed.

Amcor now couples a broad global packaging footprint with fresh US focused reporting and a strong recent share price run. The real issue for you is whether that solid business is already fully reflected in today’s valuation.

Most Popular Narrative: 5.6% Undervalued

The most followed Amcor narrative puts fair value at $49.93 per share, a touch above the recent $47.15 close. That small gap is where the real debate starts for investors weighing the stock after its auditor change and recent price strength.

The integration of Berry Global with Amcor is expected to yield $650 million in synergies by fiscal 2028 (with $260 million in fiscal 2026), primarily through cost reduction, procurement optimization, and operational efficiencies, which should support sustained EPS and margin expansion.

Curious what sits behind that fair value call for Amcor. The narrative leans heavily on earnings momentum, firmer profit margins and a future valuation multiple that assumes those improvements keep holding up. The key is how those moving parts fit together in the model.

Result: Fair Value of $49.93 (UNDERVALUED)

However, the Amcor story can change quickly if volume trends stay weak or if divestitures related to the portfolio review are finalized at valuations that are lower than expected.
