Directly from PJ's site. Not sure why the Yahoo reference referred to it as an EP. It is an LP. It is released as a gatefold on vinyl with music on 3 sides and an etching on the 4th.
From Pearl Jam's Announcement:
Pearl Jam will release their much-anticipated eleventh studio album, Gigaton, on Monkeywrench Records/ Republic Records on March 27, 2020 in the US. Internationally, the album will be released and distributed by Universal Music Group International. Produced by Josh Evans and Pearl Jam, Gigaton marks the band’s first studio album since GRAMMY award-winning Lightning Bolt.
“Making this record was a long journey,” explains Mike McCready . “It was emotionally dark and confusing at times, but also an exciting and experimental road map to musical redemption. Collaborating with my bandmates on Gigaton ultimately gave me greater love, awareness and knowledge of the need for human connection in these times."
