SAO PAULO, Sept 15 (Reuters) - Brazil's Embraer SA said on Thursday that it signed a memorandum of understanding with Apollo Global Management to provide up to $1.5 billion in funding for the planemaker's regional aircraft customers.

According to a securities filing, funding would be available through Apollo's aviation business, but Apollo could also "access additional low-cost capital across its broader investment platform."

Under the agreement, the companies also reached a deal for the sale and leaseback of six E195-E2s aircraft to Porter Airlines, which are scheduled for a 2023 delivery.
