Analysis · ADTN · Manufacturing
ADTRAN's Q2 revenue of $281.1M fell short of its $283M-$303M guidance range, though optical networking revenue grew 22% year-over-year. The net loss narrowed to $10.9M from $20.5M a year ago, but material weaknesses in internal controls remain unresolved. The company also disclosed a new $350M credit facility with JPMorgan, replacing its prior Wells Fargo agreement, and noted the SEC closed its investigation without action. These mixed signals — a revenue miss against a backdrop of improving profitability and a refinancing — keep the stock in a high-uncertainty zone.
