** Goldman Sachs downgrades Finnish oil refiner Neste NESTE.HE to "neutral" from "buy", citing limited upside after recent share outperformance despite a higher PT
** The broker raises its PT by over 17% to EUR 27, lifting 2026 EBITDA estimates by 32% on higher margin forecasts for both its oil refining and renewables units
** GS notes Neste's oil refining business benefits from a spike in diesel and jet fuel prices, with its Finnish refinery largely insulated from supply chain disruptions
** Higher diesel prices also provide short-term tailwinds for the renewables division, but GS sees "rising risks to biofuel mandates on rising affordability concerns"
** The brokerage warns high inflation in Europe creates risks for biofuel mandates, noting Germany could revise its targets, hurting Neste's 2027-2030 renewables earnings
** The downgrade comes as the stock has outperformed its sector by 25 percentage points since February, with the new PT implying 4% downside from current levels - GS
** Out of 23 analysts that cover Neste, 11 rate the stock "strong buy" or "buy,"seven rate "hold" and five rate the stock "strong sell" or "sell" - LSEG
