This is possibly exciting. Its metallicity is almost identical to that of the Sun. If hypothetically it were the best case scenario, something broadcasted by a sentient being, then the position that the universe simply isn't old enough to be densely populated becomes a lessor issue. Considering that our sun is a third or fourth generation star, based on its metallicity/age and if heavier elements are necessary for advanced civilizations to evolve - it's possible that the intergalactic space race is only just beginning.
