SAO PAULO (Reuters) -Brazilian planemaker Embraer on Monday kept its outlook for the full year unchanged but acknowledged it might be closer to meeting the low end of its delivery target range as it continues to grapple with supply chain issues. Embraer will need to deliver at least 26 commercial and 54 executive jets in the final three months of the year to meet its goals, nearly in line with the performance it posted in the same period of last year. "We have a big challenge for deliveries in the fourth quarter, but as we demonstrated in the fourth quarter of 2022, we are prepared for it," Chief Financial Officer Antonio Carlos Garcia told a conference call with analysts.
