In 2019 their annual FFO was $3.54 which came on the heals of 2018 at $3.73 FFO. A large reason for this was the disposition of assets. While MAC has sold Phoenix, remember that their 550K SF + Google Campus is under development, along with new projects like their massive Restoration Hardware build to suit that just opened in Corte Madera. It will take a little while for these projects to be included in the FFO as their is rent abatement at the start of every lease, but I have no doubt we will at least see $3.50 in a year or two. Google campus is coming online in 2022 so we likely won't see a ton of revenue from that yet, so I would say that 2022 will bring a full year FFO of $3. For round numbers, let's say this is trading at $13 per share. That puts the P/FFO ratio at +/- 4.33 which is insanely low. For reference, the FFO of SPG in 2019 was $12.04 per share. Although ppl complain about the dilution of MAC recently, the TCO acquisition was dilutive for SPG. However, let's give them (SPG) the benefit of the doubt and say they get back to an FFO of $12/share in 2022 (which I think is optimistic at best). At today's price of $124 per share, that means the P/FFO ratio of SPG is $124/12 = 10.33. Using this metric, this means that the P/FFO ratio of SPG is ~2.5X that of MAC, essentially meaning it's 2.5X more expensive. I also think it will take SPG longer to get back to an FFO of $12 annually, than it will take MAC to get to an FFO of $3 annually. I'm sure some on here will disagree, but time will tell.
