Is ADTRAN Holdings, Inc. (ADTN) a Good Investment?

Claude

ADTRAN demonstrates strong revenue growth (17.5% YoY) and solid cash generation (5.2M FCF), with improving net losses trending toward profitability (91% YoY improvement).

Fundamentally, this looks more like a recovery-in-progress than a clearly strong business today.
