Dec. 31, 2022
Accounting Policies [Abstract] |
Fiscal Year | Fiscal Year The Company uses a fiscal calendar year ending on June 30. All references herein to “fiscal 2023” represent the fiscal year ending June 30, 2023. All references herein to “fiscal 2022” represent the fiscal year ended June 30, 2022.
Principles of Consolidation | Principles of Consolidation The unaudited condensed consolidated financial statements include the accounts of Extreme and its wholly owned subsidiaries. All inter-company accounts and transactions have been eliminated. The Company predominantly uses the United States Dollar as its functional currency. The functional currency for certain of its foreign subsidiaries is the local currency. For those subsidiaries that operate in a local functional currency environment, all assets and liabilities are translated to United States Dollars at current month end rates of exchange and revenues and expenses are translated using the monthly average rate.
Accounting Estimates | Accounting Estimates The preparation of financial statements and related disclosures in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from these estimates.
Recently Adopted and Recently Issued Accounting Pronouncements | Recently Adopted and Recently Issued Accounting Pronouncements In December 2022, the Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update (“ASU”) 2022-06, Reference Rate Reform (Topic 848): Deferral of the Sunset Date of Topic 848, which extends the period of time entities can utilize the reference rate reform relief guidance under ASU 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting from December 31, 2022 to December 31, 2024. Upon issuance of ASU 2020-04, the Company elected to apply certain of the optional expedients for contract modifications to its financial instruments impacted by the London Interbank Offered Rate (“LIBOR”) discontinuance. The Company expects to continue to elect various optional expedients for contract modifications to the Company’s financial instruments affected by the reference rate reform through the effective date of December 31, 2024, as extended by ASU 2022-06. The application of this guidance did not have any impact on our consolidated financial statements.
Revenue Recognition | Revenue Recognition Performance Obligations. A performance obligation is a promise in a contract to transfer a distinct good or service to the customer and is the unit of account in Topic 606. A contract’s transaction price is allocated to each distinct performance obligation and recognized as revenue when, or as, the performance obligation is satisfied. Certain of the Company’s contracts have multiple performance obligations, as the promise to transfer individual goods or services is separately identifiable from other promises in the contracts and, therefore, is distinct. For contracts with multiple performance obligations, the Company allocates the contract’s transaction price to each performance obligation based on its relative standalone selling price. The stand-alone selling prices are determined based on the prices at which the Company separately sells these products. For items that are not sold separately, the Company estimates the stand-alone selling prices using other observable inputs. The Company’s performance obligations are satisfied at a point in time or over time as the customer receives and consumes the benefits provided. Substantially all of the Company’s product sales revenues are recognized at a point in time. Substantially all of the Company’s service, subscription, and SaaS revenues are recognized over time. For revenues recognized over time, the Company uses an input measure, days elapsed, to measure progress. On December 31, 2022, the Company had $445.6 million of remaining performance obligations, which are primarily comprised of deferred maintenance and SaaS revenues. The Company expects to recognize approximately 36% of its deferred revenue as revenue in the remainder of fiscal 2023, an additional 34% in fiscal 2024 and 30% of the balance thereafter. Contract Balances. The timing of revenue recognition, billings and cash collections results in billed accounts receivable and deferred revenue in the condensed consolidated balance sheets. Services provided under renewable support arrangements of the Company are billed in accordance with agreed-upon contractual terms, which are either billed fully at the inception of contract or at periodic intervals (e.g., quarterly or annually). The Company sometimes receives payments from its customers in advance of services being provided, resulting in deferred revenues. These liabilities are reported on the condensed consolidated balance sheets on a contract-by-contract basis at the end of each reporting period. Revenue recognized for the three months ended December 31, 2022 and 2021 that was included in the deferred revenue balance at the beginning of each period was $83.9 million and $81.9 million, respectively. Revenue recognized for the six months ended December 31, 2022 and 2021 that was included in the deferred revenue balance at the beginning of each period was $145.7 million and $132.5 million, respectively. Contract Costs. The Company recognizes the incremental costs of obtaining contracts as an expense when incurred if the amortization period of the assets that the Company otherwise would have recognized is one year or less. Management expects that commission fees paid to sales representatives as a result of obtaining service and subscription contracts and contract renewals are recoverable and therefore the Company’s condensed consolidated balance sheets included capitalized balances in the amount of $17.5 million and $16.3 million at December 31, 2022 and June 30, 2022, respectively. Capitalized commissions are included within other assets in the condensed consolidated balance sheets. Capitalized commission fees are amortized on a straight-line basis over the average period of service contracts of approximately three years, and are included in “Sales and marketing” in the accompanying condensed consolidated statements of operations. Amortization recognized during the three months ended December 31, 2022 and 2021, was $ 2.2 million and $1.8 million, respectively. Amortization recognized during the six months ended December 31, 2022 and 2021, was $4.3 million and $3.6 million, respectively. Estimated Variable Consideration. There were no material changes in the current period to the estimated variable consideration for performance obligations, which were satisfied or partially satisfied during previous periods. Revenue s by Category The Company operates in three geographic regions: Americas, EMEA (Europe, Middle East and Africa) and APAC (Asia Pacific). The following table sets forth the Company’s revenues disaggregated by sales channel and geographic region based on the billing addresses of its customers (in thousands):

For the six months ended December 31, 2022 the Company generated 10% each of its revenues from the Netherlands and Germany. For the six months ended December 31, 2021 the Company generated 10% of its revenues from the Netherlands. No other foreign country accounted for 10% or more of revenue for the three and six months ended December 31, 2022 and 2021.
Inventories | Inventories Inventories are stated at the lower of cost, determined on the first-in, first-out (“FIFO”) basis, or net realizable value. Extreme uses a standard cost methodology to determine the cost basis for its inventories. Cost is computed using standard cost, which approximates actual cost, on a first-in, first-out basis. The Company adjusts the carrying value of its inventory when conditions exist that suggest that inventory may be in excess of anticipated demand or is obsolete based upon assumptions about future demand. At the point of loss recognition, a new, lower-cost basis for that inventory is established, and subsequent changes in facts and circumstances do not result in the restoration or increase in that newly established cost basis. Any previously written down or obsolete inventory subsequently sold has not had a material impact on gross margin for any of the periods presented. Inventories consist of the following (in thousands):
|  | December 31, 2022 |  |  | June 30, 2022 |
Finished goods |  | $ | 55,721 |  |  | $ | 40,733 |

Deferred Revenue | Deferred Revenue Deferred revenue represents amounts for deferred maintenance, support, SaaS, and other deferred revenue including professional services and training when the revenue recognition criteria have not been met.
Guarantees and Product Warranties | Guarantees and Product Warranties The majority of the Company’s hardware products are shipped with either a one-year warranty or a limited lifetime warranty, and software products receive a 90-day warranty. Upon shipment of products to its customers, the Company estimates expenses for the cost to repair or replace products that may be returned under warranty and accrues a liability in cost of product revenues for this amount. The determination of the Company’s warranty requirements is based on actual historical experience with the product or product family, estimates of repair and replacement costs and any product warranty problems that are identified after shipment. The Company estimates and adjusts these accruals at each balance sheet date in accordance with changes in these factors. The following table summarizes the activity related to the Company’s product warranty liability during the three and six months ended December 31, 2022 and 2021 (in thousands):
|  | Three Months Ended |  |  | Six Months Ended |  |

To facilitate sales of its products in the normal course of business, the Company indemnifies its resellers and end-user customers with respect to certain matters. The Company has agreed to hold the customer harmless against losses arising for intellectual property infringement and certain other losses. These agreements may limit the time within which an indemnification claim can be made and the amount of the claim. It is not possible to estimate the maximum potential amount under these indemnification agreements due to the limited history of prior indemnification claims and the unique facts and circumstances involved in each particular agreement. Historically, payments made by the Company under these agreements have not had a material impact on its operating results or financial position.
Concentrations | Concentrations The Company may be subject to concentration of credit risk as a result of certain financial instruments consisting of accounts receivable. See Note 3, Revenues, for the Company’s accounts receivable concentration. The Company does not invest an amount exceeding 10% of its combined cash in the securities of any one obligor or maker, except for obligations of the United States government, obligations of United States government agencies and money market accounts.
Earnings Per Share | Basic net income per share is calculated by dividing net income by the weighted-average number of shares of common stock outstanding during the period. Diluted income per share is calculated by dividing net income by the weighted-average number of shares of common stock used in the basic net income per share calculation plus the dilutive effect of shares subject to repurchase, options and unvested RSUs.
