Graphic Packaging Holdings (GPK.US): Pricing environment still murky, but risk/reward has improved. U/g to Overweight

J.P. Morgan upgraded Graphic Packaging Holdings (GPK) from Neutral to Overweight while lowering its Dec-2027 price target to $11.50/sh from $12.50/sh. Since GPK's Q2'26 earnings on Aug 4, the shares are down ~19% (SPX 500: -1%) due to (1) a re-acceleration in input cost inflation related to the Middle East conflict, (2) no third-party (RISI) recognition of the announced CUK and CRB price increases, and (3) concerns that this may lead to an FY'26 EBITDA guidance miss. However, supply/demand has improved: the Greif-owned Sweetwater mill plans to close before year-end, removing ~60ktpa of CRB capacity (~3% of existing capacity) and ~60ktpa of URB capacity, while tariffs and temporary closures cut import volumes by ~200ktpa, tightening the SBS market. Cost-driven price increases have been implemented for CUK and CRB grades for non-RISI linked customers (~50% of volumes), and pricing has upside risk. At current levels GPK trades at a 2027 P/E of 9.3x, more than one standard deviation below
