10 Q3 Fiscal 2022 • Financial Highlights Net revenue was $78 million, a year-over-year decrease of 18 percent. The decrease was primarily driven by fewer new and existing customer orders as a result of fewer active customers and the reduction in advertising spend with Grove’s prioritization of increasing profitability. The decrease in orders was partly offset by an increase in AOVs and an increase in retail revenue. Gross margin was down 130 bps year-over-year to 49.1% due to an increase in product costs, including inbound freight costs, an increase in sales from retail sales, which produce lower margins than our DTC channel sales, and an increase to inventory reserves, partially offset by the impacts of net revenue management initiatives including the introduction of strategic price increases on Grove Brands and third party products. GROSS MARGIN NET REVENUE ($MM)

Adjusted EBITDA Margin improved 2,040 bps year-over-year, driven primarily by reduced operating and advertising costs, offset by a lower gross margin and higher outbound shipping costs. 11 Q3 Fiscal 2022 • Financial Highlights ADJUSTED EBITDA MARGIN Net Income/Loss Margin improved 4,930 bps year-over-year, primarily driven due to improved Adjusted EBITDA margin and the decrease in the fair value of the Earn-Out liability. NET INCOME/LOSS MARGIN

12 Q3 Fiscal 2022 • Financial Highlights DTC Total orders were down 26% year-over-year due to a decrease in active customers, along with the decrease in direct advertising spend in early 2022 as the company focuses on profitability, resulting in fewer new and existing customer orders. DTC Active customers were down 15% year-over-year following COVID-related tailwinds in 2021. Similar to orders, the reduction of customer acquisition spend also contributed to this decline as the company shifts its focus to profitability. DTC ACTIVE CUSTOMERS (M)DTC TOTAL ORDERS (K)

Grove Brands as a percent of net revenue declined year-over-year to 47% driven by strong 3rd party Fall seasonal performance, YoY decrease in new customer orders which tend to include more Grove brand products as well as a mix shift of advertising spend into channels with less Grove Brands promotion. DTC net revenue per order continued its long-term upward trend, increasing 7% year-over-year to $61. The improvement in revenue per order was driven primarily by improved existing customer Average Order Value and the impacts of net revenue management initiatives including the introduction of strategic price increases on Grove Brands and third party products. 13 Q3 Fiscal 2022 • Financial Highlights DTC NET REVENUE PER ORDER GROVE BRANDS % NET REVENUE

Non-GAAP Financial Measures 19 Grove Collaborative uses the non-GAAP financial measures set forth below in assessing its operating performance and in its financial communications. Management believes these non-GAAP financial measures provide useful additional information to investors about current trends in the Company's operations and are useful for period-over-period comparisons of operations. In addition, management uses these non-GAAP financial measures to assess operating performance and for business planning purposes. Management also believes these measures are widely used by investors, securities analysts, rating agencies and other parties in evaluating companies in our industry as a measure of our operational performance. These non-GAAP financial measures should not be considered in isolation or as a substitute for the comparable GAAP measures. In addition, these non-GAAP financial measures may not be computed in the same manner as similarly titled measures used by other companies. Adjusted EBITDA and Adjusted EBITDA as a % of net revenues We calculate adjusted EBITDA as net loss, adjusted to exclude: (1) stock-based compensation expense; (2) depreciation and amortization; (3) remeasurement of convertible preferred stock warrant liability; (4) changes in fair values of Additional Shares, Earn-out Shares and Public and Private Placement Warrant liabilities; (5) transaction costs allocated to derivative liabilities upon Business Combination; (6) interest expense; (7) provision for income taxes; (8) restructuring expenses and (9) loss on extinguishment on debt.
