GROVE COLLABORATIVE CONFIDENTIAL Our Journey Beyond Plastic TODAY Plastic Neutral At Grove, our Plastic Neutral program ensures that for every ounce of plastic we sell, an ounce of ocean-bound plastic is recycled through our partnership with rePurpose Global. STEP 1 Measure We weigh and record the amount of plastic in every product. Using those numbers, we calculate how much plastic we’re sending to customers in each order. STEP 2 Collect In partnership with rePurpose Global, we collect and recycle an ounce of ocean and nature-bound plastic for every ounce of plastic we sell. BY 2025 Beyond Plastic Beyond Plastic™ is our plan to solve the single-use plastic problem for home and personal care products. Today, we’re 100% plastic neutral. By 2025, Grove Co. will meet our Beyond Plastic™ standard. PHASE 1 Beyond Plastic We’re the first online retailer to be 100% plastic neutral.

We’re working hard to remove plastic from everything we make and sell. 6

77 OUR TOTAL PLASTIC FOOTPRINT BEYOND PLASTIC: TRACKING OUR PROGRESS* We are the first in our industry to report on our plastic given its materiality to our business. We're using this scorecard to challenge our industry to track and publish their plastic use. 665,067 lbs TOTAL PLASTIC WEIGHT Total weight of plastic we shipped to our customers and sold through retail partners in the fourth quarter of 2022, including every brand and every product that we sell at Grove. *Metrics as of 12/31/2022 unless otherwise noted; please note that “Net Revenue” on this slide refers to net revenue that is directly traceable to products sold Beyond Plastic™ 65% of Grove Brands net revenue came from either zero-plastic, re-usable or refillable and zero plastic waste products in the fourth quarter of 2022, up from 49% in the fourth quarter of 2021. 65% Grove Brands Across the Grove site and through retail partners, we shipped 0.98 lbs of plastic for every $100 in product net revenue in the fourth quarter of 2022, an improvement from 1.21 pounds in the fourth quarter of 2021. This ratio enables us to decouple our plastic footprint from our revenue and truly pin our success to plastic reduction. 0.98 lbs / $100 in Net Revenue PLASTIC INTENSITY PLASTIC INTENSITY Across all Grove Brands, we shipped 0.80 lbs of plastic for every $100 in product net revenue in the fourth quarter of 2022, an improvement from 0.99 pounds in the fourth quarter of 2021, showcasing a reduced use of plastic in our owned brands, which are designed for sustainability. 0.80 lbs / $100 in Net Revenue Site-wide and through retail partners, 16% of our products were reusable or refillable in 2022, compared to 13% in the prior year.

10 Q4 and Fiscal 2022 • Financial Highlights Net revenue was $74 million, a year over year decrease of 15 percent. The decrease was primarily driven by fewer DTC orders caused by a reduction in active customers. The decline in active customers is a result of reduced advertising spend as Grove prioritizes profitability over growth, and was partially offset by an increase in DTC net revenue per order and strong customer loyalty. Gross margin improved 200 bps year over year to 47.0%, mainly driven by the impacts of net revenue management initiatives, including the introduction of strategic price increases on Grove Brands and third party products, and fewer discounts from an improved promotional strategy, offset by an increase in product costs, including inbound freight costs. Full year margin was 48.1%. GROSS MARGIN NET REVENUE ($MM)

Adjusted EBITDA Margin improved 1,610 bps to -12.9% year over year. This reflects an improved gross margin coupled with lower operating and advertising costs reflective of our strategy to streamline SG&A functions and only spend in the most profitable acquisition channels. 11 Q4 and Fiscal 2022 • Financial Highlights ADJUSTED EBITDA MARGIN Net Loss Margin improved 1,950 bps to -17.1% year over year, primarily driven due to improved Adjusted EBITDA margin and the gain for changes in the fair value of the Earn-Out liability, offset by increases in interest expense, restructuring, and loss on debt extinguishment. NET LOSS MARGIN

12 Q4 and Fiscal 2022 • Financial Highlights DTC Total orders were down 25% year-over-year due to a decrease in active customers driven by the decrease in direct advertising spend throughout 2022 as the company focuses on profitability. DTC Active customers were down 16% year-over-year due to the reduction in DTC advertising spend as the company continues to shift its focus to profitability and spend in the most profitable advertising channels resulting in fewer new and existing customer orders, and following COVID-related tailwinds. DTC ACTIVE CUSTOMERS (K)DTC TOTAL ORDERS (K)

Grove Brands as a percent of net revenue declined 220 bps year-over-year to 46% driven by the launch of a larger number of new third party products to our website when compared to Grove Brand products, as we continue to expand our offerings, and a decrease in new customer orders which tend to include more Grove brand products. DTC net revenue per order increased 11% year-over-year to $63 primarily driven by the impacts of Net Revenue Management initiatives focused on strategic pricing, on both third party and Grove brand products, and on the optimization of DTC Net Revenue per order with the initiation of a supply chain fee 13 Q4 and 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) interest income; (8) provision for income taxes, (9) restructuring expenses and (10) loss on extinguishment of debt. We define Adjusted EBITDA Margin as Adjusted EBITDA divided by revenue. $K Reconciliation of Net (Loss) Income to Adjusted EBITDA Q4 2022 Q4 2021 FY 2022 FY 2021 FY 2020 Net loss $ (12,683) $ (31,987) $ (87,715) $ (135,896) $ (72,260) Stock-based compensation 11,312 3,752 45,660 14,610 7,762 Depreciation and amortization 1,425 1,359 5,716 4,992 4,115 Remeasurement of convertible preferred stock warrant liability — (292) (1,616) 1,234 964 Change in fair value of Additional Shares liability (243) — 727 — — Change in fair value of Earn-Out liability (20,223) — (66,359) — — Change in fair value of public and private placement warrants liability (1,917) — (5,900) — — Transaction costs allocated to derivative liabilities upon Business Combination - — 6,873 — — Interest Income (521) — (521) — — Interest Expense 2,767 1,930 9,685 5,202 5,607 Restructuring Expenses 5,887 — 8,879 — — Loss on extinguishment of debt 4,663 — 4,663 1,027 — Provision for income taxes 19 13 54 52 41 Adjusted EBITDA $ (9,515) $ (25,225) $ (79,854) $ (108,779) $ (53,771) Net Loss margin -17.1% -36.7% -27.3% -35.4% -19.8% Adjusted EBITDA margin -12.9% -28.9% -24.8% -28.4% -14.8%
