Exhibit 99.1

Greif, Inc. Updates Fiscal Second Quarter 2021 Guidance

Greif, Inc. a global leader in industrial packaging products and services, announced today that it has revised its outlook for fiscal second quarter 2021. Fiscal second quarter 2021 diluted Class A earnings per share before adjustments is now expected to be in the range of $1.11 – $1.15 per share, compared to the Company's previous guidance range of $0.96 – $1.06 per share.1

The improved guidance range is mainly due to stronger than anticipated volumes and selling prices in the Global Industrial Packaging business and a slightly lower than anticipated tax rate, partially offset by higher than anticipated SG&A expense mainly due to higher incentive accruals.

The Company will report its fiscal second quarter 2021 financial results after the market closes on Wednesday, June 9, 2021. A conference call will be held on Thursday, June 10, 2021 at 8:30 a.m. ET. Conference call details can be found at

The most directly comparable GAAP financial measure, the expected fiscal second quarter 2021 diluted Class A earnings per share on a GAAP basis, is not provided herein due to the potential for one or more of the following, the timing and magnitude of each of which the Company at this point remains unable to reliably forecast on an individual basis with probability: gains or losses on the disposal of businesses, timberland or properties, plants and equipment, net; non-cash asset impairment charges; restructuring charges; non-cash incremental COVID-19 costs, net; non-cash pension settlement (income) charges; or acquisition and integration related costs; and the income tax effects of these items and other income tax-

related events. As a result, no reconciliation of the expected fiscal second quarter 2021 Class A earnings per share before adjustments to the most directly comparable GAAP financial measure is included in this release.
