GPK: Rounding Bottom detected on 5 Jun 2026

GPK is forming a rounding bottom pattern after months of weakness following full-year 2025 net sales of $8.6 billion versus $8.8 billion in 2024. Current price of $10.64 sits 54% below the 52-week high but 21% above the 52-week low, indicating nascent recovery. Structure score of 13/15 reflects solid base formation, though volume at 0.79x average (10/12) and breakout score of 12/13 suggest moderate confirmation. The rounding bottom forms with key support at $8.78 and resistance at $19.64. RSI at 53.6 indicates neutral positioning. MACD histogram at 0.0483 shows early bullish momentum. Overall pattern quality scores 69/98 with 64.7% win probability.

GPK reported Q1 2026 results on May 5, 2026 with net sales up 2% year-over-year to $2,156 million but posted a net loss of $43 million versus $127 million net income in Q1 2025. The company completed a 90-day comprehensive business review and is advancing near-term strategic priorities while reaffirming 2026 adjusted cash flow guidance of $700-800 million. In February 2026, the company amended its credit agreement to increase maximum leverage ratio covenants to 5.0x through December 2026, from prior 4.25x, indicating balance sheet pressures. The prior CEO resigned and GPK shares lost more than half their value from guidance failures in 2025. GPK is presenting at the Wells Fargo Industrials & Materials Conference on June 9, 2026.

A successful rounding bottom breakout would target the conservative price of $11.10, representing a modest 4.3% move from current levels. Above $11.10, resistance escalates to $19.64—a 84% extended target. The measured move relies on volume confirmation; current relative volume of 0.79x is below average, so breakout validity requires volume expansion above the 7.6M average. Invalidation occurs below the $8.78 key support level, which would signal base failure and renewed downtrend. The 64.7% win probability reflects moderate confidence in bullish resolution, with beta of 1.38 indicating heightened volatility.

GPK issued guidance in February 2025 for $8.9 billion in net sales and $2.78 adjusted EPS but delivered adjusted EBITDA of only $1.43 billion, triggering a 50% stock collapse and subsequent CEO resignation. A securities class action lawsuit was filed alleging investors were misled about business stability and financial outlook, with a lead plaintiff deadline of July 6, 2026. The complaint alleges false statements regarding inventory management, demand trends, and cost pressures. Sector regime is bearish at -0.41, adding headwind despite broader bullish market. Beta of 1.38 and volatility of 51.5% indicate elevated risk. Volume ratio of 0.79 signals weak conviction in current recovery attempt. Q2 results are tentatively scheduled for August 4, 2026—significant catalyst risk.
