Additional 402(v) Disclosure

Amounts represent the average of the amounts reported for the Company’s Non-PEO NEOs as a group in the “Total” column of the “Summary Compensation

Table” in each applicable year.

(4)TSR is determined based on the value of an initial fixed investment of $100 on December 31, 2019. Cumulative TSR is calculated by dividing the sum of the

cumulative amount of dividends for the measurement period, assuming dividend reinvestment, and the difference between the Company’s stock price at the

end and the beginning of the measurement period by the Company’s stock price at the beginning of the measurement period.

Net income attributable to Alexandria as reported in the Company’s Annual Report on Form 10-K for the applicable fiscal year.
