Iron Mountain is trading 8.96% down at $108.03 after its November 5 earnings release, as revenue guidance missed analyst estimates. - Third-quarter results were strong; fourth-quarter revenue guidance was about $2.03 billion and the full-year midpoint $7.99 billion, below estimates of $2.05 billion and $8.04 billion, respectively. - Record data center leasing reached 102 megawatts; the company raised full-year guidance and its dividend, but positives did not offset outlook concerns. - The broader REIT sector is higher, making sector weakness less likely.
