AdAction's Top Stability & Growth Strengths

Strong Market Position & Advantage: Repeated placements in AppsFlyer’s 2025 Performance Index and 14 appearances in Singular’s 2026 ROI Index point to meaningful visibility and effectiveness across gaming and non-gaming categories.

Innovation-Driven Growth: U.S. online sales are expanding at sustained double-digit rates (+14.3% in Q1 and +14.5% in Q2 2026), supported by the completed PRISM omnichannel platform and the rollout of the Edge retail media offering. E‑commerce profitability in 2025 and ongoing AI/automation initiatives further reinforce a tech-enabled growth flywheel.

Future-Ready Strategy: The company is investing for long-term growth through an $860 million North Carolina distribution center, a multi‑year $1 billion U.S. price‑investment program, and accelerated remodels/new stores. Targets to lift omnichannel loyalty penetration and app usage by 2028 and a push toward 45% private‑label penetration underscore forward-leaning execution.

Resilient & Sustainable Growth: U.S. comparable sales remained positive in 2026 to date (+1.5% in Q1; +0.8% in Q2), and management reiterated full‑year 2026 guidance after both quarters. Market‑share gains across most U.S. brands were noted even as group net sales growth was modest (+1.9% at constant rates in Q2).
