2021年第四季度补充信息零售机会投资公司11250 El Camino Real，Suite200 San Diego，CA 92130 www.roireit.net

我们公司零售机会投资公司(纳斯达克代码：ROIC)是一家完全集成、自我管理的房地产投资信托公司，专门从事收购、拥有和管理位于西海岸人口稠密的大都市市场的杂货店购物中心。截至2021年12月31日，ROIC拥有89个购物中心，总面积约为1020万平方英尺。ROIC是最大的上市、以食品杂货为基础的购物中心，REIT专门专注于西海岸。ROIC是标准普尔SmallCap 600指数成份股公司之一，拥有穆迪投资者服务公司(Moody‘s Investor Services)、标准普尔全球评级公司(S&P Global Ratings)和惠誉评级公司(Fitch Ratings，Inc.)的投资级公司债务评级。补充信息所附信息应与ROIC提交给证券交易委员会的文件一并阅读，包括但不限于其每季度提交的10-Q表格和每年提交的10-K表格。此外，所附资料并不旨在披露公认会计原则(“公认会计原则”)下的所有项目。非GAAP披露运营资金(“FFO”)是一种广为认可的REITs非GAAP财务衡量标准，公司认为，当与根据GAAP呈报的财务报表一起考虑时，它为评估其财务业绩提供了额外和有用的手段。FFO经常被证券分析师、投资者和其他相关方用来评估REITs的业绩，其中大多数REITs都是根据GAAP计算的FFO和净利润。公司根据全美房地产投资信托协会(“NAREIT”)发布的“FFO白皮书”计算FFO。, FFO定义为普通股股东应占净收益(根据GAAP确定)，不包括债务重组、可折旧财产销售和减值的收益或亏损，加上房地产相关折旧和摊销，以及对合伙企业和未合并合资企业进行调整后的净收益。公司内部使用现金净营业收入(“NOI”)来评估和比较公司物业的经营业绩。本公司相信现金NOI向投资者提供有关本公司财务状况及经营业绩的有用资料，因为它只反映在物业层面发生的收入及支出项目，而当跨期间比较时，可用于厘定本公司物业的收益趋势，因为此衡量标准不受非现金收入及支出确认项目、本公司融资成本、折旧及摊销费用的影响、收购及出售营运房地产资产的损益、一般及行政开支或与本公司有关的其他损益影响。该公司认为，将这些项目从营业收入中剔除是有用的，因为由此产生的衡量标准反映了经营公司物业所产生的实际收入和发生的实际费用，以及入住率、租金和运营成本的趋势。现金NOI是衡量公司物业经营业绩的指标，但不能衡量公司的整体业绩，因此不能替代按照公认会计原则计算的净收入或营业收入。公司将现金NOI定义为营业收入(基本租金和从租户那里收回), 减去物业及相关费用(物业营运费用及物业税)，经直线租金及租赁无形资产摊销、债务相关费用及其他调整等非现金收入及营运费用项目调整。现金NOI还不包括一般和行政费用、折旧和摊销、收购交易成本、其他费用、利息支出、物业收购和处置的损益、非常项目、租户改善和租赁佣金。其他REITs可能使用不同的方法来计算现金NOI，因此，公司的现金NOI可能无法与其他REITs相比。概述截至2021-2年12月31日的补充披露季度-
