** UBS initiates tax advisory firm Andersen ANDG.N with a "buy" rating, sets PT of $28, 15% upside to last close

** Brokerage says ANDG is well positioned to continue to expand its long-tenured Managing Director-led business model

** We believe that the market is not capturing the impact of revenue growth and/or future productivity as well as the growing potential international opportunity, brokerage says

** Adds ANDG is well positioned for ~13% estimated organic revenue growth in 2024 to 2027

** ANDG enjoys significant financial benefits by not providing audit or financial statement attestation services as it reduces client conflicts and expenses like professional liability insurance, brokerage says
