** UBS upgrades Spanish hotel chain Melia Hotels MEL.MC to "neutral" from "sell", citing an improved equity story with a focus on margin expansion
** UBS revises its 2026-2027 estimates for the company following "somewhat better-than-expected" Q4 top-line results
** The brokerage also raises price target to 8.60 euros ($9.98), about 10% above Melia's current share price
** Still, UBS says it needs clearer evidence of structural improvement to gain confidence in Melia's ambition to lift EBITDA margins to 30% by 2027
** Melia has limited exposure to the Middle East, as it only has two hotels in the United Arab Emirates, UBS says
** Including today's fall, the stock has dropped around 2.3% YTD
