+ Details

- Definition

Total of all stockholders' equity (deficit) items, net of receivables from officers, directors, owners, and affiliates of the entity which are attributable to the parent. The amount of the economic entity's stockholders' equity attributable to the parent excludes the amount of stockholders' equity which is allocable to that ownership interest in subsidiary equity which is not attributable to the parent (noncontrolling interest, minority interest). This excludes temporary equity and is sometimes called permanent equity.

Accounting Policies [Abstract]

Overview

Note 1: Overview

Ooma, Inc. and its wholly-owned subsidiaries (collectively, “Ooma” or the “Company”) provides leading communications services and related technologies for businesses and consumers, delivered from its smart software-as-a-service (“SaaS”) and unified communications platforms. The Company is headquartered in Sunnyvale, California.

Fiscal Year. The Company’s fiscal year ends on January 31. References to fiscal 2023 and fiscal 2022 refer to the fiscal year ending January 31, 2023 and the fiscal year ended January 31, 2022, respectively.

Basis of Presentation. The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) and applicable rules and regulations of the Securities and Exchange Commission (“SEC”) regarding interim financial reporting. Certain information and note disclosures normally included in the financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules and regulations. The condensed consolidated balance sheet as of January 31, 2022 included herein was derived from the audited financial statements as of that date, but does not include all the disclosures required by GAAP. Therefore, the information included in this Quarterly Report on Form 10-Q should be read in conjunction with the audited consolidated financial statements and related notes included in the Company’s Annual Report on Form 10-K for the year ended January 31, 2022 filed with the SEC on April 8, 2022 (“Annual Report”).

The accompanying condensed consolidated financial statements reflect all normal recurring adjustments that management believes are necessary for a fair presentation of the interim periods presented. The results for the three months ended April 30, 2022 are not necessarily indicative of the results to be expected for any subsequent quarter or for the fiscal year ending January 31, 2023.

Principles of Consolidation. The condensed consolidated financial statements include the accounts of Ooma, Inc. and its wholly-owned subsidiaries. All intercompany transactions and balances have been eliminated in consolidation.

Use of Estimates. The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the Company’s condensed consolidated financial statements and notes thereto. Significant estimates include, but are not limited to, those related to revenue recognition, inventory valuation, deferred sales commissions, valuation of goodwill and intangible assets, operating lease assets and liabilities, regulatory fees and indirect tax accruals, loss contingencies, stock-based compensation and income taxes (including valuation allowances). The Company bases its estimates and assumptions on historical experience, where applicable, and other factors that it believes to be reasonable under the circumstances. These estimates are based on information available as of the date of the consolidated financial statements, and assumptions are inherently subjective in nature. Therefore, actual results could differ from management’s estimates.

Significant Accounting Policies. There have been no material changes to the Company’s significant accounting policies from those disclosed in the Annual Report.

Comprehensive Loss. For all periods presented, comprehensive loss approximated net loss in the condensed consolidated statements of operations and differences were not material. Therefore, the condensed consolidated statements of comprehensive loss have been omitted.

Revenue and Deferred Revenue

Revenue From Contract With Customer [Abstract]

Revenue and Deferred Revenue

Note 2: Revenue and Deferred Revenue

The Company derives its revenue from two sources:

Subscription and Services Revenue is derived primarily from recurring subscription fees related to service plans such as Ooma Business, Ooma Residential and other communications services. Service plans are generally sold as monthly subscriptions; however, certain plans are also offered as annual or multi-year subscriptions. Subscription revenue is generally recognized ratably over the contractual service term.

Product and Other Revenue is generated primarily from the sale of on-premise appliances and end-point devices, including shipping and handling fees for direct customers. The Company recognizes product and other revenue from sales to direct end-customers and channel partners at the point-in-time that control transfers, which is typically when it delivers the product.

Revenue disaggregated by revenue source consisted of the following (in thousands):

	Three Months Ended
	April 30, 2022		April 30, 2021
Subscription and services revenue	$	46,723	$	41,965
Product and other revenue		3,614		3,607
Total revenue	$	50,337	$	45,572

The Company derived approximately 50% and 47% of its total revenue from Ooma Business and approximately 47% and 51% from Ooma Residential for the three months ended April 30, 2022 and 2021, respectively. No individual country outside of the United States, and no single customer, represented 10% or more of total revenue for the periods presented.

Customers who represented 10% or more of net accounts receivable were as follows:

	As of
	April 30, 2022	January 31, 2022
Customer A	14%	19%
Customer B	*	11%

* Less than 10% of net accounts receivable for the period indicated.

Deferred Revenue primarily consists of billings or payments received in advance of meeting revenue recognition criteria. Deferred services revenue is recognized on a ratable basis over the term of the contract as the services are provided.

	As of
	April 30, 2022		January 31, 2022
Subscription and services	$	16,392	$	16,614
Product and other		58		59
Total deferred revenue	$	16,450		16,673
Less: current deferred revenue		16,392		16,600
Non-current deferred revenue included in other long-term liabilities	$	58	$	73

During the three months ended April 30, 2022, the Company recognized revenue of approximately $9.9 million pertaining to amounts deferred as of January 31, 2022. As of April 30, 2022, deferred revenue was primarily composed of subscription contracts invoiced during the first quarter of fiscal 2023, as well as amounts recorded during fiscal 2022 for annual contracts.

Remaining Performance Obligations. As of April 30, 2022, contract revenue that had not yet been recognized for open contracts with an original expected length of greater than one year was approximately $9.1 million. The Company expects to recognize revenue on approximately 53% of this amount over the next 12 months, with the balance to be recognized thereafter.

- Definition

The entire disclosure of revenue from contract with customer to transfer good or service and to transfer nonfinancial asset. Includes, but is not limited to, disaggregation of revenue, credit loss recognized from contract with customer, judgment and change in judgment related to contract with customer, and asset recognized from cost incurred to obtain or fulfill contract with customer. Excludes insurance and lease contracts.

Fair Value Measurements

Fair Value Disclosures [Abstract]

Fair Value Measurements

Note 3: Fair Value Measurements

The Company estimates and categorizes fair value by applying the following hierarchy:

Level 1:

Quoted prices (unadjusted) for identical assets or liabilities in active markets.

Level 2:

Observable prices based on inputs not quoted in active markets, but are corroborated by market data.

Level 3:

Unobservable inputs that are supported by little or no market activity.

Financial assets measured at fair value on a recurring basis by level were as follows (in thousands):

	Balance as of April 30, 2022
	Level 1		Level 2		Total
Cash and cash equivalents:
Money market funds	$	2,434	$	—	$	2,434
Commercial paper		—		1,299		1,299
Total cash equivalents	$	2,434	$	1,299	$	3,733
Cash					$	17,920
Total cash and cash equivalents					$	21,653

Short-term investments:
U.S. treasury securities	$	5,037	$	—	$	5,037
Corporate debt securities		—		3,341		3,341
Commercial paper		—		1,749		1,749
Total short-term investments	$	5,037	$	5,090	$	10,127

	Balance as of January 31, 2022
	Level 1		Level 2		Total
Cash and cash equivalents:
Money market funds	$	2,275	$	—	$	2,275
Total cash equivalents	$	2,275	$	—	$	2,275
Cash						17,392
Total cash and cash equivalents					$	19,667

Short-term investments:
U.S. treasury securities	$	7,065	$	—	$	7,065
Commercial paper		—		4,548		4,548
Total short-term investments	$	7,065	$	4,548	$	11,613

The Company classifies its cash equivalents and short-term investments within Level 1 or Level 2 because it uses quoted market prices or alternative pricing sources and models utilizing market observable inputs to determine their fair value. The Company has no Level 3 assets or liabilities. For the periods presented, the amortized cost of cash equivalents and marketable securities approximated their fair value and there were no material realized or unrealized gains or losses, either individually or in the aggregate.

Contractual maturities of short-term investments were as follows (in thousands):

	As of
	April 30, 2022		January 31, 2022
Due in one year or less	$	9,644	$	10,377
Due after one year to two years		483		1,236
Total	$	10,127	$	11,613

Income Taxes

Note 8: Income Taxes

The Company recorded income tax expense of $40 thousand during the three months ended April 30, 2022 and no income tax expense or benefit during the three months ended April 30, 2021. The Company continues to maintain a full valuation allowance against its deferred tax assets.

As of April 30, 2022, the Company had unrecognized tax benefits of $8.5 million, none of which would currently affect the Company's effective tax rate if recognized due to the Company's deferred tax assets being fully offset by a valuation allowance. The Company does not anticipate that the amount of unrecognized tax benefits relating to tax positions existing at April 30, 2022 will significantly increase or decrease within the next twelve months. There were no interest expense or penalties related to unrecognized tax benefits recorded through April 30, 2022.

A number of years may elapse before an uncertain tax position is audited and finally resolved. While it is often difficult to predict the final outcome or the timing of resolution of any particular uncertain tax position, the Company believes that its reserves for income taxes reflect the most likely outcome. The Company adjusts these reserves, as well as the related interest, in light of changing facts and circumstances. Settlement of any particular position could require the use of cash.

- Definition

The entire disclosure for income taxes. Disclosures may include net deferred tax liability or asset recognized in an enterprise's statement of financial position, net change during the year in the total valuation allowance, approximate tax effect of each type of temporary difference and carryforward that gives rise to a significant portion of deferred tax liabilities and deferred tax assets, utilization of a tax carryback, and tax uncertainties information.

Basic and Diluted Net Loss Per Share

3 Months Ended

Apr. 30, 2022

Earnings Per Share [Abstract]

Basic and Diluted Net Loss Per Share

Note 9: Basic and Diluted Net Loss Per Share

Basic and diluted net loss per share is calculated by dividing the net loss by the weighted-average number of common shares outstanding during the period. Diluted net loss per share of common stock is the same as basic net loss per share of common stock because the effects of potentially dilutive securities are antidilutive as the Company reported net losses for all periods presented.

The following table sets forth the computation of the Company’s basic and diluted net loss per share of common stock (in thousands, except share and per share data):

	Three Months Ended
	April 30, 2022			April 30, 2021
Numerator
Net loss	$	(766	)	$	(887	)
Denominator
Weighted-average common shares		24,116,144			23,053,512
Basic and diluted net loss per share	$	(0.03	)	$	(0.04	)

Potentially dilutive securities of approximately 3.8 million shares were excluded from the computation of diluted net loss per share for each of the three months ended April 30, 2022 and 2021. These shares included the Company’s outstanding RSUs, outstanding stock options and stock purchase rights under the ESPP at the end of the respective period. In the event the Company reported net income for the periods presented, a portion of these outstanding securities would be reflected in weighted-average shares outstanding for diluted earnings per share by application of the treasury method.

Financing Arrangements

Note 10: Financing Arrangements

Revolving Credit Facility

On January 8, 2021, the Company, as borrower, entered into a credit and security agreement (“Credit Agreement”) with KeyBank National Association as Administrative Agent (“Agent”) and lender, and KeyBanc Capital Markets Inc. as sole lead arranger and sole book runner. The Credit Agreement provides for a secured revolving credit facility (“Credit Facility”) under which the Company may borrow up to an aggregate amount of $25.0 million, which includes a $10.0 million sub-facility for letters of credit. The Company and its lenders may increase the total commitments under the Credit Facility to up to an aggregate amount of $45.0 million, subject to certain conditions. Funds borrowed under the Credit Agreement may be used for working capital and other general corporate purposes.

Loans under the Credit Agreement will bear interest, at the Company’s option, at either a rate equal to the “Base Rate” (as defined in the Credit Agreement) or (b) “Eurodollar Rate” (as defined in the Credit Agreement) plus 2.50%. The Base Rate is the highest of (i) the Agent’s prime rate, (ii) the federal funds effective rate plus 0.5%, and (iii) the Eurodollar Rate with an interest period of one month plus 1%. The Eurodollar Rate is the London Interbank Offered Rate with various interest periods as may be selected by the Company but shall not be less than 0.75%. Upon the occurrence of any event of default, the interest rate on any borrowings increases by 2.0%. The Credit Agreement also contains customary provisions for the replacement of the London Interbank Offered Rate/Eurodollar Rate. The Company is required to pay a commitment fee on the unused portion of the Credit Facility of 0.25% per annum.

The Credit Agreement contains customary representations, warranties, affirmative and negative covenants, events of default and indemnification provisions in favor of the Agent, lenders and their affiliates. Among other covenants, the Credit Agreement includes restrictive financial covenants that require the Company to meet minimum recurring revenue levels and maintain specified amounts of available liquidity on a quarterly basis.

As of April 30, 2022, the Company had zero outstanding borrowings and was in compliance with the covenants contained in the Credit Agreement. Accordingly, $25.0 million of borrowing capacity was available for the purposes permitted by the Credit Agreement.

Note 11: Commitments and Contingencies

Purchase Commitments

As of April 30, 2022 and January 31, 2022, non-cancelable inventory purchase commitments to contract manufacturers and other parties were $17.9 million and $19.4 million, respectively.

Additionally, the Company has a non-cancelable service agreement with a telecommunications provider that contains total annual minimum purchase commitments of $0.6 million between August 2021 and July 2022, $1.5 million between August 2022 and July 2023 and $2.5 million between August 2023 and July 2024.

Legal Proceedings

In addition to the litigation matters described below, from time to time, the Company may be involved in a variety of other claims, lawsuits, investigations, and proceedings relating to contractual disputes, intellectual property rights, employment matters, regulatory compliance matters, and other litigation matters relating to various claims that arise in the normal course of business. Defending such proceedings is costly and can impose a significant burden on management and employees, the Company may receive unfavorable preliminary or interim rulings in the course of litigation, and there can be no assurances that favorable final outcomes will be obtained.

The Company determines whether an estimated loss from a contingency should be accrued by assessing whether a loss is deemed probable and can be reasonably estimated. The Company assesses its potential liability by analyzing specific litigation and regulatory matters using reasonably available information. The Company develops its views on estimated losses in consultation with inside and outside counsel, which involves a subjective analysis of potential results and outcomes, assuming various combinations of appropriate litigation and settlement strategies. Legal fees are expensed in the period in which they are incurred.

As of April 30, 2022, the Company did not have any accrued liabilities recorded for loss contingencies in its consolidated financial statements.

Oregon Tax Litigation

On August 30, 2016, the Oregon Department of Revenue (the “DOR”) issued tax assessments against the Company for the Oregon Emergency Communications Tax (the “Tax”), which the DOR alleges Ooma should have collected from its subscribers in Oregon and remitted to the DOR during the period between January 1, 2013 and March 31, 2016 (collectively, the “Assessments”). The Company believes that the Commerce Clause of the United States Constitution bars the application of the Tax and the Assessments to the Company, since the Company has no employees, property or other indicia of a “substantial nexus” with the State of Oregon.

On March 2, 2020, Oregon Tax Court issued a decision upholding the Assessments, and on December 23, 2021, the Supreme Court of Oregon issued a decision upholding the Assessments. The Company has filed a petition for writ of certiorari with the United States Supreme Court. However, litigation is unpredictable and there can be no assurances that the Company will obtain a favorable final outcome, even assuming the United States Supreme Court grants the Company’s petition. In prior fiscal years, the Company recorded and has paid cumulative charges of $0.6 million to the DOR as its best estimate of probable loss related to the Assessments.

Canadian Litigation

On February 3, 2021, plaintiff Fiona Chiu filed a class action complaint against the Company and Ooma Canada Inc. in the Federal Court of Canada, alleging violations of Canada’s Trademarks Act and Competition Act. The complaint seeks monetary and other damages and/or injunctive relief enjoining the Company to cease describing and marketing its Basic Home Phone using the word “free” or otherwise representing that it is free. On November 9, 2021, the Federal Court of Canada removed Ms. Chiu and substituted John Zanin as the new plaintiff in the proceeding. In connection with the substitution of Mr. Zanin as the new plaintiff, the Federal Court of Canada deemed the proceeding as having commenced on November 8, 2021 instead of February 3, 2021. In January 2022, the Federal Court of Canada heard arguments from counsel representing each of the Company and Mr. Zanin regarding jurisdiction and class action certification issues, and the parties are awaiting the Court to issue its ruling. The Company intends to continue to defend itself vigorously against this complaint. Based on the Company’s current knowledge, the Company has determined that the amount of any reasonably possible loss resulting from the Canadian Litigation is not estimable.

Indemnification

The Company enters into standard indemnification arrangements in the ordinary course of business. Pursuant to these arrangements, the Company indemnifies, holds harmless and agrees to reimburse the indemnified parties for losses suffered or incurred by the indemnified party, in connection with any trade secret, copyright, patent or other intellectual property infringement claim by any third party with respect to the Company’s technology. The term of these indemnification agreements is generally perpetual. The maximum potential amount of future payments the Company could be required to make under these agreements is not determinable because it involves claims that may be made against the Company in the future but have not yet been made.

The Company has entered into indemnification agreements with its directors and officers that may require the Company to indemnify its directors and officers against liabilities that may arise by reason of their status or service as directors or officers, other than liabilities arising from willful misconduct of the individual. The maximum potential amount of future payments the Company could be required to make under these indemnification agreements is unlimited; however, the Company has director and officer insurance coverage that reduces the Company’s exposure and enables the Company to recover a portion of any future amounts paid.

To date the Company has not incurred costs to defend lawsuits or settle claims related to these indemnification agreements. No liability associated with such indemnifications has been recorded to date.

Accounting Policies [Abstract]
Fiscal Year	Fiscal Year. The Company’s fiscal year ends on January 31. References to fiscal 2023 and fiscal 2022 refer to the fiscal year ending January 31, 2023 and the fiscal year ended January 31, 2022, respectively.
Basis of Presentation	Basis of Presentation. The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) and applicable rules and regulations of the Securities and Exchange Commission (“SEC”) regarding interim financial reporting. Certain information and note disclosures normally included in the financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules and regulations. The condensed consolidated balance sheet as of January 31, 2022 included herein was derived from the audited financial statements as of that date, but does not include all the disclosures required by GAAP. Therefore, the information included in this Quarterly Report on Form 10-Q should be read in conjunction with the audited consolidated financial statements and related notes included in the Company’s Annual Report on Form 10-K for the year ended January 31, 2022 filed with the SEC on April 8, 2022 (“Annual Report”). The accompanying condensed consolidated financial statements reflect all normal recurring adjustments that management believes are necessary for a fair presentation of the interim periods presented. The results for the three months ended April 30, 2022 are not necessarily indicative of the results to be expected for any subsequent quarter or for the fiscal year ending January 31, 2023.
Principles of Consolidation	Principles of Consolidation. The condensed consolidated financial statements include the accounts of Ooma, Inc. and its wholly-owned subsidiaries. All intercompany transactions and balances have been eliminated in consolidation.
Use of Estimates	Use of Estimates. The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the Company’s condensed consolidated financial statements and notes thereto. Significant estimates include, but are not limited to, those related to revenue recognition, inventory valuation, deferred sales commissions, valuation of goodwill and intangible assets, operating lease assets and liabilities, regulatory fees and indirect tax accruals, loss contingencies, stock-based compensation and income taxes (including valuation allowances). The Company bases its estimates and assumptions on historical experience, where applicable, and other factors that it believes to be reasonable under the circumstances. These estimates are based on information available as of the date of the consolidated financial statements, and assumptions are inherently subjective in nature. Therefore, actual results could differ from management’s estimates.
Significant Accounting Policies	Significant Accounting Policies. There have been no material changes to the Company’s significant accounting policies from those disclosed in the Annual Report.
Comprehensive Loss	Comprehensive Loss. For all periods presented, comprehensive loss approximated net loss in the condensed consolidated statements of operations and differences were not material. Therefore, the condensed consolidated statements of comprehensive loss have been omitted.
