Explanation of Responses:

1. On November 5, 2025, the reporting person converted a total of 13,144 long-term incentive plan units ("LTIP Units") of STAG Industrial Operating Partnership, L.P., a Delaware limited partnership (the "Operating Partnership"), of which STAG Industrial, Inc., a Maryland corporation (the "Issuer"), is the sole member of the general partner, into 13,144 common units of limited partnership of the Operating Partnership ("OP Units") and redeemed 13,144 OP Units. The LTIP Units are convertible into OP Units as they are nonforfeitable and certain conditions to parity have been satisfied. The OP Units held by the reporting person are redeemable for cash equal to the 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. The Issuer elected to redeem the reporting person's OP Units with common stock.

2. Represents LTIP Units granted to the reporting person pursuant to the Equity Incentive Plan. Over time, the LTIP Units can achieve full parity with 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.

3. Represents OP Units in the Operating Partnership. OP Units 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. The OP Units are vested as of the date of issuance and have no expiration date.
