13 Q2 Fiscal 2022 • Financial Highlights Net revenue was $79 million, a year-over-year decrease of 20 percent. The decrease was primarily driven by fewer new and existing customer orders as a result of fewer active customers and the reduction in advertising spend with Grove’s prioritization of increasing profitability and managing customer acquisition costs. Gross margin was slightly down 40 bps year-over-year to 49.1% as a result of increased discounts due to a less favorable environment as the pandemic subsides and an increase in inbound freight costs, partially offset by strong third party seasonal product margins. GROSS MARGIN NET REVENUE ($MM)

Adjusted EBITDA Margin declined 540 bps year-over-year, driven primarily by the increased SG&A costs as a % of net revenue, higher outbound shipping costs from price increases and surcharges, and slightly lower gross margin. 14 Q2 Fiscal 2022 • Financial Highlights ADJUSTED EBITDA MARGIN Net Loss Margin declined 1570 bps year-over-year, primarily driven by increased SG&A costs as a % of net revenue, higher outbound shipping costs from price increases and surcharges, and slightly lower gross margin, coupled with an increase in non-cash expenses as part of the business combination that closed during Q2. Refer to Adjusted EBITDA reconciliation later in the presentation for more detail on these adjustments. NET LOSS MARGIN

15 Q2 Fiscal 2022 • Financial Highlights DTC Total orders were down 22% year-over-year due to lower order retention from a decrease in active customers, along with a decrease in direct advertising spend in early 2022 as the company focuses on profitability. DTC Active customers were down 10% 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 gained 30 bps year-over-year to 48.2% driven by improvement in existing customer orders, slightly offset by new customer orders as a result of mix shift of advertising spend into channels with less Grove Brands promotion. DTC net revenue per order continued its long-term upward trend, increasing 3% year-over-year to $58.3. The quarter benefited from improved existing customer Average Order Value and VIP Membership revenue per order, resulting in increased revenue. 16 Q2 Fiscal 2022 • Financial Highlights DTC NET REVENUE PER ORDER GROVE BRANDS % NET REVENUE

Non-GAAP Financial Measures 22 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. We define Adjusted EBITDA Margin as Adjusted EBITDA divided by revenue. $K (1) Note: 1.
