The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries and have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) and the requirements of the U.S. Securities and Exchange Commission (“SEC”) for year end financial reporting. All intercompany balances and transactions have been eliminated in consolidation. The Company reclassified the balance within "Impairment, restructuring and other" on the consolidated statements of operations for the prior period into "Selling, general and administrative expenses" ("SG&A") to conform to the current period presentation. The Company reclassified the balance of customer deposits, totaling $18,273 as of December 31, 2021, previously reported in "Accounts payable" into "Deferred revenue" in the consolidated balance sheet as of December 31, 2021, to conform to the current period presentation. Consistent with the reclassifications on the consolidated balance sheet, the Company made corresponding reclassifications to conform with the current period presentation in the consolidated statement of cash flows.

The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Estimates are based on historical experience and on various other assumptions that are believed to be reasonable under the circumstances. Significant estimates include provisions for sales returns, rebates and claims from customers, realization of accounts receivable and inventories, fair value of assets acquired and liabilities assumed for business combinations, valuation of intangible assets and goodwill, estimated useful lives of long-lived assets, incremental borrowing rate applied in lease accounting, valuation of stock-based compensation, recognition of deferred income taxes, recognition of liabilities related to commitments and contingencies and valuation allowances. Actual results may differ from these estimates. On an ongoing basis, the Company reviews its estimates to ensure that these estimates appropriately reflect changes in its business or new information available.

Acquisitions of businesses are accounted for using the acquisition method. The consideration transferred in a business combination is measured at fair value, which is calculated as the sum of the acquisition date fair values of the assets transferred, liabilities incurred to the former owners of the acquiree, and the equity interests issued in exchange for control of the acquiree. Acquisition related costs are recognized in net (loss) income as incurred.

When the consideration transferred in a business combination includes assets or liabilities resulting from a contingent consideration arrangement, the contingent consideration is measured at its acquisition date fair value and included as part of the consideration transferred in a business combination. Contingent consideration is established for business acquisitions where the Company has the obligation to transfer additional assets or equity interests to the former owners if specified future events occur or conditions are met. Contingent consideration is classified as a liability when the obligation requires settlement in cash or other assets and is classified as equity when the obligation requires settlement in the Company's own equity instruments. Changes in the fair value of the contingent consideration that qualify as measurement period adjustments are adjusted retrospectively, with a corresponding adjustment to goodwill. Measurement period adjustments are adjustments that arise from additional information obtained during the measurement period (which cannot exceed one year from the acquisition date) about facts and circumstances that existed at the acquisition date. All other subsequent changes in the fair value of contingent consideration classified as a liability are included in net (loss) income in the period. Changes in the fair value of contingent consideration classified as equity are not recognized.

For a given acquisition, the Company may identify certain pre-acquisition contingencies as of the acquisition date and may extend its review and evaluation of these pre-acquisition contingencies throughout the measurement period to obtain sufficient information to assess these contingencies as part of acquisition accounting, as applicable.

Goodwill is measured as the excess of the sum of the consideration transferred, the amount of any non‑controlling interests in the acquiree, and the fair value of the acquirer’s previously held equity interest in the acquiree (if any) over the net of the acquisition‑date fair value amounts of the identifiable assets acquired, and the liabilities assumed.

If the initial accounting for a business combination is incomplete by the end of the reporting period in which the combination occurs, the Company reports provisional amounts for the items for which the accounting is incomplete. Those provisional amounts are adjusted during the measurement period, or additional assets or liabilities are recognized, to reflect new information obtained about facts and circumstances that existed at the acquisition date that, if known, would have affected the amounts recognized at that time. Upon conclusion of the measurement period or final determination of the values of assets acquired or liabilities assumed, whichever comes first, any subsequent adjustments are recorded to net (loss) income.

The Company began a restructuring plan during the quarter ended December 31, 2022, and is undertaking significant actions to streamline operations, reduce costs and improve efficiencies. The major initiatives of the restructuring plan include (i) narrowing the Company's product and brand portfolio and (ii) the relocation and consolidation of certain manufacturing and distribution centers, including headcount reductions and reorganization to drive a solution based approach.

During the year ended December 31, 2022, the Company recorded pre-tax charges of $6,790 relating to the inventory markdowns of products and brands being removed from our portfolio, which is primarily non-cash, and $897 relating primarily to the relocation and termination of certain facilities in Canada, which are primarily cash charges. The Company's strategic product consolidation entails removing approximately one-third of all products and one-fifth of all brands relating to our primary product portfolio, which excludes our garden center business in Canada. The Company expects the restructuring and related actions to result in cost savings of approximately $7,000 on an annualized basis. The amounts the Company will ultimately realize or disburse could differ from these estimates.

The Company recorded $7,466 of restructuring related charges within Cost of goods sold and $221 within Selling, general and administrative expenses on the consolidated statement of operations for the year ended December 31, 2022. The Company's accrued liability for restructuring costs as of December 31, 2022, was $696. The Company estimates it will incur additional restructuring charges of approximately $1.7 million during the first half of 2023.

The Company's chief operating decision maker is the chief executive officer ("CEO") who reviews financial information for the purposes of making operating decisions, assessing financial performance and allocating resources. The business is organized as two operating segments, the U.S. and Canada, which meet the criteria for aggregation, and the Company has elected to present them as one reportable segment, which is the distribution and manufacture of CEA equipment and supplies. Aggregation is based on similarities which include the nature of its products, production or acquisition of inventory, customer base, fulfillment and distribution and economic characteristics.

Sales to external customers and property, plant and equipment, and operating lease right-of-use assets, net in the United States and Canada, determined by the location of the subsidiaries, are shown below. Other foreign locations, which are immaterial, individually and in the aggregate, are included in the U.S. below.

The Company maintains cash balances at certain financial institutions that can, at times, exceed amounts insured by the Federal Deposit Insurance Corporation (“FDIC”). The Company has not experienced any losses in these accounts and believes it is not exposed to any significant credit risk in this area.

Accounts receivable expose the Company to credit risks such as collectability and business risks such as customer concentrations. Exposure to losses on receivables is dependent on each customer’s financial condition. Receivables arising from sales are not collateralized; however, credit risk is somewhat mitigated as a result of the large diverse customer base. No customer accounted for more than 10% of revenues in 2022, or 2021. No customer accounted for more than 10% of accounts receivable as of December 31, 2022, or December 31, 2021. One supplier accounted for more than 10% of purchases in 2022 and 2021.

Level 2 — Valuation techniques based on inputs that are quoted prices of similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not in active markets; inputs other than quoted prices used in a valuation model that are observable for that instrument; and inputs that are derived from or, corroborated by, observable market data by correlation or other means.

The Company measures certain non-financial assets and liabilities, including long-lived assets, intangible assets and goodwill, at fair value on a nonrecurring basis. The fair value of contingent consideration is classified within level 3 of the fair value hierarchy (See discussion of contingent consideration in Note 3 - Business Combinations and Note 15 - Fair Value Measurements).

The Company reports its financial results in United States dollars, which is the currency of the primary economic environment in which it operates. The functional currency for each of the Company’s foreign subsidiaries is generally its local currency. Monetary assets and liabilities, and transactions denominated in currencies other than the functional currency are remeasured to the functional currency at the exchange rate in effect at the end of each period. Foreign currency transaction gains and losses are included in the determination of net (loss) income and classified as other income (expense), net in the consolidated statements of operations. Assets and liabilities of foreign subsidiaries are translated at the exchange rates in effect at the end of each period. Revenues, expenses, gains and losses are translated at the average rates of exchange prevailing during the period. Accumulated deficit and other equity accounts are translated at historical rates. Translation gains and losses are included in accumulated other comprehensive loss within stockholders’ equity.

Cash includes funds deposited in banks. Cash equivalents include highly liquid investments such as term deposits and money market instruments with original maturities of three months or less. As of December 31, 2021, amounts included in restricted cash represent those funds required to be set aside as security for letters of credits, and other various contractual arrangements. As of December 31, 2022, there were no amounts classified as restricted cash, as all previous restrictions lapsed during the year.

Trade accounts receivable represents amounts due from customers. Other receivables represent other current non-trade receivables. Allowance for doubtful accounts reflects the Company’s estimate of amounts in its existing accounts receivable that may not be collected due to customer claims or customer inability or unwillingness to pay. The allowance is determined based on a combination of factors, including, but not limited to the age of the account, the credit worthiness of the customer, payment terms, the customer’s historical payment history and general economic conditions. Management reviews these factors quarterly to determine if any adjustments are needed to the allowance for doubtful accounts. Accounts receivable are written off when the receivables are deemed uncollectible.

Inventories consist of finished goods, work-in-process, and raw materials used in manufacturing products. Inventories are stated at the lower of cost or net realizable value, principally determined by the first in, first out method of accounting. The Company maintains an allowance for excess and obsolete inventory. The estimate for excess and obsolete inventory is based upon assumptions about current and anticipated demand, customer preferences, business strategies, and market conditions.

Management reviews these assumptions periodically to determine if any adjustments are needed to the allowance for excess and obsolete inventory. The establishment of an allowance for excess and obsolete inventory establishes a new cost basis in the inventory. Such allowance is not reduced until the product is sold. If inventory is sold, any related reserves would be reversed in the period of sale. The Company estimates inventory markdowns relating to restructuring charges based upon current and anticipated demand, customer preferences, business strategies, and market conditions including management's actions with respect to inventory products and brands being removed from our portfolio. Hydrofarm's strategic product consolidation entails removing approximately one-third of all products and one-fifth of all brands relating to our primary product portfolio.

Leases are accounted for under Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC") 842, Leases. At inception of a contract, the Company determines whether that contract is or contains a lease. A contract is or contains a lease if the contract conveys the right to control the use of identified property, plant, or equipment (an identified asset) for a period of time in exchange for consideration. Leases are then classified as either finance or operating, with classification affecting the location of expense recognition in the consolidated statements of operations.

Right-of-use assets ("ROU") represent the right to use an underlying asset for the lease term while lease liabilities represent the obligation to make lease payments arising from a lease, measured on a discount basis. All leases greater than 12 months result in the recognition of a ROU and a lease liability at the lease commencement date based on the present value of the lease payments over the lease term. The present value of the lease payments is calculated using the applicable weighted-average discount rate. The weighted-average discount rate is based on the discount rate implicit in the lease, or if the implicit rate is not readily determinable from the lease, the applicable incremental borrowing rate is estimated. The incremental borrowing rate is estimated using the currency denomination of the lease and the contractual lease term. To determine the incremental borrowing rate, reference is made to interest rates that would be available to finance assets similar to the assets under lease in their related geographical location.

The Company accounts for lease components separately from non-lease components, other than for office equipment. The Company has certain leases that include one or more options to renew with renewal terms that can extend the lease term. The exercise of the lease renewal options is at the Company’s discretion. A lease renewal option is included in the determination of the ROU asset and lease liability when the option is reasonably certain of being exercised.

Definite-lived intangible assets are amortized using the straight-line method over their estimated useful lives. The Company has one trade name that is considered to have an indefinite useful life. Intangible assets are also tested for impairment at least annually and when events or changes in circumstances indicate that, more-likely-than-not, the carrying

Goodwill represents the excess of the acquisition price of an acquired business over the fair value of the identifiable assets acquired and liabilities assumed in a business combination less any subsequent write-downs for impairment. Goodwill is tested for impairment on an annual basis in the fourth quarter and more frequently if indicators of potential impairment exist. Impairment testing is conducted at the reporting unit level, which is generally defined as an operating segment or one level below an operating segment (also known as a component), for which discrete financial information is available and segment management regularly reviews the operating results. The Company has determined that its reporting units for the purpose of goodwill impairment testing are the U.S. and Canada.

Goodwill impairment reviews include performing either an initial qualitative or quantitative evaluation for each of the reporting units. Several methods may be used to estimate a reporting unit’s fair value, including market quotations, asset and liability fair values and other valuation techniques. If the carrying amount of a reporting unit, including goodwill, exceeds the estimated fair value, then the excess is charged to earnings as an impairment loss.

In 2019, the Company executed a note receivable secured by equipment to a third-party, the terms of which were amended and restated during the first quarter of 2021. The note receivable provided for interest and installment payments to the Company, and full maturity of the note in 2024. During the first quarter of 2022 the third-party defaulted on interest payments, and the Company measured an impairment on the note receivable based on the estimated fair value of the collateral. The Company recorded an impairment loss of $2,636 during the year ended December 31, 2022, respectively, in “Impairments” on the consolidated statements of operations. There were no impairment losses recorded in the year ended December 31, 2021. As of December 31, 2022, the note receivable carrying value was $475 and is classified in Other assets on the consolidated balance sheet.

ASC 606, Revenue from Contracts with Customers, requires that revenue recognized from contracts with customers be disaggregated into categories that depict how the nature, amount, timing and uncertainty of revenue and cash flows are affected by economic factors. The Company has determined that revenue is generated from one category, which is the distribution and manufacture of controlled environment agriculture equipment and supplies.

Revenue is recognized as control of promised goods is transferred to customers, which generally occurs upon receipt at customers’ locations determined by the specific terms of the contract. Arrangements generally have a single performance obligation and revenue is reported net of variable consideration which includes applicable volume rebates, cash discounts and sales returns and allowances. Variable consideration is estimated and recorded at the time of sale.

The amount billed to customers for shipping and handling costs included in net sales was $13,180, and $8,050 in 2022, and 2021, respectively. Shipping and handling costs that occur before the customer obtains control of the goods are deemed to be fulfillment activities and are accounted for as fulfillment costs included in cost of goods sold. The Company does not receive noncash consideration for the sale of goods. Contract consideration received from a customer prior to revenue recognition is recorded as a contract liability and is recognized as revenue when the Company satisfies the related performance obligation under the terms of the contract. The Company's contract liabilities, which consist primarily of customer deposits are reported within deferred revenue in the consolidated balance sheets, totaled $3,654 and $18,273 as of December 31, 2022, and 2021, respectively. There are no significant financing components. Excluded from revenue are any taxes assessed by governmental authorities, including value-added and other sales-related taxes that are imposed on and concurrent with revenue-generating activities.

The Company generally accounts for warrants issued in connection with debt and equity financings as a component of equity unless the warrants include a conditional obligation to issue a variable number of shares among other conditions or it is possible that the Company may need to settle the warrants in cash.

The Company accounts for stock-based compensation expense in accordance with the fair value recognition and measurement provisions of U.S. GAAP, which requires compensation cost for the grant-date fair value of stock-based awards to be recognized over the requisite service period. The Company accounts for forfeitures when they occur and any compensation expense previously recognized on unvested shares will be reversed when forfeited.

The fair value of grants of restricted stock is based on the fair value of the common stock underlying the award. The fair value of the underlying common stock for RSUs prior to the Company’s IPO in December 2020, was determined by considering a number of objective, subjective, and highly complex factors including independent third-party valuations of the Company’s common stock, operating and financial performance, the lack of liquidity of capital stock and general and industry specific economic outlook among other factors. For awards granted after the Company's IPO, the fair value of the underlying common stock for RSUs is the closing date price of the Company's common stock at the grant-date.

The fair value of option-based awards is estimated using the Black-Scholes valuation model. The Black-Scholes model requires the use of highly subjective and complex assumptions. For inputs into the Black-Scholes model, the expected volatility is based on historical implied volatility from recent stock option transactions at the time of grant. The risk-free interest rate for the expected term of the option is based on the U.S. Treasury implied yield at the date of grant. The Company has elected to use the “simplified method” to determine the expected term which is the midpoint between the vesting date and the end of the contractual term because it has insufficient history upon which to base an assumption about the term. The expected dividend yield is 0.0% as the Company has not paid and does not anticipate paying dividends on its common stock.

The Company has granted performance stock unit ("PSU") awards that vest upon the satisfaction of both service-based and performance-based conditions. The service-based condition for these awards generally is satisfied over one year. The performance-based conditions generally are satisfied upon achieving specified performance targets. The Company records stock-based compensation expense for performance-based equity awards on a straight-line basis over the requisite service period and only if performance-based conditions are considered probable to be satisfied.

The Company has granted RSUs that vest only upon the satisfaction of both performance-based and market-based conditions. The performance-based conditions are satisfied upon achieving specified performance targets, such as the occurrence of a qualifying event, as described above for performance-based awards. The market-based condition is satisfied upon the Company’s achievement of a qualifying traded share price within the specified time frame. The Company records stock-based compensation expense once the performance condition is satisfied regardless of whether the market condition is eventually met. For one award granted in 2020, the market condition was factored into its fair value and the Company used a "Monte Carlo Simulation Method" ("MCSM") to estimate the fair value of the award. The MCSM assessed the likelihood of vesting of the RSU grants based on the probability of both a triggering event and qualifying traded share price within the specified time frame. For the years ended December 31, 2022, and 2021, there were no performance awards with market-based conditions granted.

The asset and liability method of accounting for income taxes is followed whereby deferred income tax assets are recognized for deductible temporary differences and operating loss carryforwards, and deferred income tax liabilities are recognized for taxable temporary differences. Temporary differences are the differences between the amounts of assets and liabilities recorded for income tax and financial reporting purposes.

Deferred income tax assets are recognized only to the extent that management determines that it is more-likely-than-not that the deferred income tax assets will be realized. Deferred income tax assets and liabilities are adjusted for the effects of changes in tax laws and rates on the date of enactment. The income tax expense or benefit is the income tax payable or recoverable for the year plus or minus the change in deferred income tax assets and liabilities during the year.

The Company has deferred tax assets and liabilities and maintains valuation allowances where it is more likely than not that all or a portion of deferred tax assets will not be realized. Significant judgment is required in determining any valuation allowance recorded against deferred tax assets. The determination of the amount of valuation allowance to be provided on recorded deferred tax assets involves consideration of estimates regarding the timing and amount of the reversal of taxable temporary differences, expected future taxable income by jurisdiction, and the impact of tax planning strategies. Changes in the relevant facts can impact the judgment or need for valuation allowances. In the event we change our determination as to the amount of deferred tax assets that can be realized, we will adjust our valuation allowance with a corresponding impact to the provision for income taxes in the period in which such determination is made.

The Company will establish a liability for tax return positions when there is uncertainty as to whether the position will ultimately be sustained. Amounts for uncertain tax positions will be adjusted when new information becomes available or when positions are effectively settled. The Company will recognize interest expense and penalties related to these unrecognized tax benefits within income tax expense. U.S. GAAP provides that a tax benefit from an uncertain tax position may be recognized when it is more-likely-than-not that the position will be sustained upon examination, including resolutions of any related appeals or litigation processes, based on the technical merits of the position. The amount recognized is measured as the largest amount of tax benefit that has a greater than 50% likelihood of being realized upon ultimate settlement with the related tax authority.
