X4 Pharmaceuticals reported a notable revenue decline in Q4 2026, with total revenue decreasing by $26.1 million to $2.7 million compared to the same period last year. The operating loss widened to $20.3 million partly due to decreased revenues and adjusted expenses, despite a significant EPS improvement from -0.35 to -0.22 vs consensus. The company remains focused on progressing its clinical trial for mavorixafor while addressing operational challenges.
