Id	Content
F1	The long-term incentive plan units ("LTIP Units") of STAG Industrial Operating Partnership, L.P., a Delaware limited partnership ("Operating Partnership"), of which STAG Industrial, Inc., a Maryland corporation (the "Issuer"), is the sole member of the general partner, were granted to the reporting person on January 8, 2026 pursuant to the Issuer's 2011 Equity Incentive Plan, as amended. The LTIP Units vest on a quarterly basis over a one-year period.
F2	Over time, the LTIP Units can achieve full parity with common units of limited partnership of the Operating Partnership ("OP Units") for all purposes. If such parity is reached, non-forfeitable LTIP Units may be converted into OP Units and then may be redeemed for cash equal to the then-current market value of one share of the Issuer's common stock or, at the Issuer's election, for shares of the Issuer's common stock on a one-for-one basis. LTIP Units do not have an expiration date.
