NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (unaudited)

1 - Basis of Presentation and Significant Accounting Policies

The accompanying interim condensed consolidated financial statements of Natus Medical Incorporated (“we,” “us,” or “our”) have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”). Except where noted below within Note 1, the accounting policies followed in the preparation of the interim condensed consolidated financial statements are consistent in all material respects with those presented in Note 1 to the consolidated financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2020.

Interim financial reports are prepared in accordance with the rules and regulations of the Securities and Exchange Commission; accordingly, the reports do not include all of the information and notes required by GAAP for annual financial statements. The interim financial information is unaudited, and reflects all normal adjustments that are, in the opinion of management, necessary for the fair presentation of our financial position, results of operations, and cash flows for the interim periods presented. We have made certain reclassifications to the prior period to conform to current period presentation. The consolidated balance sheet as of December 31, 2020 was derived from audited financial statements but does not include all disclosures required by GAAP. The accompanying financial statements should be read in conjunction with the financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2020.

Operating results for the three and six months ended June 30, 2021 are not necessarily indicative of the results that may be expected for the year ending December 31, 2021. The accompanying condensed consolidated financial statements include our accounts and our wholly owned subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation.

Impact of COVID-19 on Our Financial Statements

On March 11, 2020, the World Health Organization declared COVID-19 a global pandemic and recommended extensive containment and mitigation measures worldwide. Since that time, we established what we believe are the necessary protocols to operate safely in our manufacturing facilities, virtually engage with customers and suppliers and work remotely when possible. Our businesses continue to recover as sales in our Neuro and Newborn Care business have returned to pre-pandemic levels. Sales for our Hearing & Balance business, which are more concentrated in Europe have partially recovered, but remain below pre-pandemic levels.

Various government programs have been established to provide financial relief for businesses affected by COVID-19 including the Canada Emergency Wage Subsidy ("CEWS") and Canada Emergency Rent Subsidy ("CERS") under the COVID-19 Economic Response Plan in Canada. We received $2.9 million for payroll subsidies under CEWS during the three months ended March 31, 2021. Our policy is to account for these subsidies in the same manner as an offset to the expense they relate to in the period in which we are reasonably assured to receive payment. For the six months ended June 30, 2021 we recognized reductions of $0.4 million in cost of sales, $1.3 million in marketing and selling expense, and $1.2 million in research and development expense in the condensed consolidated statements of operations for these subsidies. No payroll subsidies were received or recognized under CEWS in prior periods. As of June 30, 2021 we have collected all amounts recorded and continue to seek additional relief as applicable.

We have assessed various accounting estimates and other matters, including those that require consideration of forecasted financial information, in context of the unknown future impacts of COVID-19 using information that is reasonably available to us at this time. The accounting estimates and other matters we assessed include, but were not limited to, our allowance for doubtful accounts, inventory and warranty reserves, stock-based compensation, goodwill and other long-lived assets, financial assets, valuation allowances for tax assets and revenue recognition. While based on our current assessment of these estimates there was not a material impact to our consolidated financial statements as of and for the three and six months ended June 30, 2021, as additional information becomes available to us, our future assessment of these estimates, including our expectations at the time regarding the

-8-

duration, scope and severity of the pandemic, as well as other factors, could materially and adversely impact our consolidated financial statements in future reporting periods.

Recently Adopted Accounting Pronouncements

None.

2 - Revenue

    Unbilled accounts receivable (“AR”) for the periods presented primarily represent the difference between revenue recognized based on the relative selling price of the related performance obligations and the contractual billing terms in the arrangements. Deferred revenue for the periods presented primarily relates to extended service contracts, installation, and training, for which the service fees are billed in advance. The associated deferred revenue is generally recognized ratably over the extended service period or when installation and training are complete.

The following table summarizes the changes in the unbilled AR and deferred revenue balances for the six months ended June 30, 2021 (in thousands):

Unbilled AR, December 31, 2020	$	1,925
Additions	62
Transferred to trade receivable	(61)
Unbilled AR, June 30, 2021	$	1,926

Deferred revenue, December 31, 2020	$	25,723
Additions	17,144
Revenue recognized	(13,723)
Deferred revenue, June 30, 2021	$	29,144

    At June 30, 2021, the short-term portion of deferred revenue of $24.4 million and the long-term portion of $4.7 million are included in deferred revenue and other long-term liabilities, respectively, in the consolidated balance sheet. As of June 30, 2021, we expect to recognize revenue associated with deferred revenue of approximately $15.9 million in 2021, $10.1 million in 2022, $1.7 million in 2023, $1.0 million in 2024, and $0.4 million thereafter.

3 - Earnings Per Share

The components of basic and diluted EPS, and shares excluded from the calculation of diluted loss per share because the effect would have been anti-dilutive, are as follows (in thousands, except per share amounts):

	Three Months Ended June 30,				Six Months Ended June 30,
	2021		2020		2021		2020
Net income (loss)	$	3,464	$	(8,903)	$	5,860	$	(12,500)

Diluted earnings (loss) per share	$	0.10	$	(0.26)	$	0.17	$	(0.37)
Shares excluded from calculation of diluted EPS	—		28		—		70

4 - Allowance for Doubtful Accounts

-9-

We estimate the lifetime allowance for doubtful, potentially uncollectible, accounts receivable upon their inception based on historical collection experience within the markets in which we operate, customer-specific information such as bankruptcy filings or customer liquidity problems, current conditions, and reasonable and supportable forecasts about the future.

Our allowance for doubtful accounts is presented as a reduction to accounts receivable on our consolidated balance sheet. When all internal efforts have been exhausted to collect the receivable, it is written off and relieved from the reserve.

The details of activity in allowance for doubtful accounts are as follows (in thousands):

	Three Months Ended June 30,				Six Months Ended June 30,
	2021		2020		2021		2020
Balance, beginning of period	$	6,085	$	7,292	$	6,213	$	7,384
Additions charged to expense	186		426		287		948
Write-offs charged against allowance	(141)		(179)		(370)		(793)
Balance, end of period	$	6,130	$	7,539	$	6,130	$	7,539

5 - Inventories

Inventories consist of the following (in thousands):

	June 30, 2021		December 31, 2020
Raw materials and subassemblies	$	19,341	$	22,583
Work in process	1,841		2,294
Finished goods	60,362		65,695
Total inventories	81,544		90,572
Less: Non-current inventories	(13,194)		(14,922)
Inventories, current	$	68,350	$	75,650

As of June 30, 2021 and December 31, 2020, we have classified $13.2 million and $14.9 million, respectively, of inventories as other assets. This inventory consists primarily of service components used to repair products held by customers pursuant to warranty obligations and extended service contracts, including service components for products we no longer sell, inventory purchased for lifetime buys, and inventory that is turning over at a slow rate. We believe these inventories will be utilized for their intended purpose.

9 - Reserve for Product Warranties

We provide a warranty for products that is generally one year in length. In some cases, regulations may require us to provide repair or remediation beyond the typical warranty period. If any of the products contain defects, we may incur additional repair and remediation costs. Service, repair and calibration services are provided by a combination of our owned facilities and vendors on a contract basis.

We accrue estimated product warranty costs at the time of sale based on historical experience. A warranty reserve is included in accrued liabilities for the expected future costs of servicing products. Additions to the reserve are based on management’s best estimate of probable liability. We consider a combination of factors including material and labor costs, regulatory requirements, and other judgments in determining the amount of the reserve. The reserve is reduced as costs are incurred to honor existing warranty and regulatory obligations.

-12-

As of June 30, 2021, we have accrued $4.8 million for product related warranties. Our estimate of these costs is primarily based upon the number of units outstanding that may require repair and costs associated with shipping.

The details of activity in the warranty reserve are as follows (in thousands):

	Three Months Ended June 30,				Six Months Ended June 30,
	2021		2020		2021		2020

Balance, end of period	$	4,802	$	5,683	$	4,802	$	5,683

Our estimate of future product warranty costs may vary from actual product warranty costs, and any variance from estimates could impact our cost of sales, operating profits and results of operations.

10 - Share-Based Compensation

As of June 30, 2021, we have one active share-based compensation plan, the 2021 Equity Incentive Plan.

The terms of all awards granted during the six months ended June 30, 2021 and the methods for determining grant-date fair value of the awards are consistent with those described in the consolidated financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2020.

Details of share-based compensation expense are as follows (in thousands):

	Three Months Ended June 30,				Six Months Ended June 30,
	2021		2020		2021		2020
Cost of revenue	$	101	$	75	$	201	$	149

Total	$	2,604	$	2,428	$	5,622	$	4,625

As of June 30, 2021, unrecognized compensation expense related to the unvested portion of stock options and other stock awards was approximately $17.9 million, which is expected to be recognized over a weighted average period of 2.4 years.

12 - Income Taxes

-13-

Our tax provision for interim periods is determined using an estimated annual effective tax rate, adjusted for discrete events arising in each respective quarter. During each interim period, we update the estimated annual effective tax rate which is subject to significant volatility due to several factors, including our ability to accurately predict the income (loss) before provision for income taxes in multiple jurisdictions, the effects of acquisitions, the integration of those acquisitions, and changes in tax law. In circumstances where we are unable to predict income (loss) in multiple jurisdictions, the actual year to date effective tax rate may be the best estimate of the annual effective tax rate for purposes of determining the interim provision for income tax.

We recorded income tax expense of $1.9 million and $2.4 million for the three and six months ended June 30, 2021, respectively. The effective tax rate was 35.4% and 28.8% for the three and six months ended June 30, 2021, respectively. We recorded a benefit from income tax of $3.9 million and $5.0 million for the three and six months ended June 30, 2020, respectively. The effective tax rate was 30.4% and 28.6% for the three and six months ended June 30, 2020, respectively. The increase in the effective tax rate for the three months ended June 30, 2021 compared with the three months ended June 30, 2020, is primarily attributable to changes in distribution of income among jurisdictions with varying tax rates and recording of additional reserves for uncertain tax positions related to a proposed audit assessment received in Denmark. Other significant factors impacting the current period effective tax rate included Federal and California research and development credits, non-deductible executive compensation expenses, and other discrete events.

We recorded one change related to unrecognized tax benefits for the three months ended June 30, 2021 related to a proposed audit assessment received in Denmark. Within the next twelve months, it is possible that the uncertain tax positions may change with a range of approximately zero to $0.2 million. Our tax returns remain open to examination as follows: U.S Federal, 2017 through 2020, U.S. states, 2016 through 2020, and significant foreign jurisdictions, generally 2016 through 2020.

13 - Debt and Credit Arrangements

    We have a Credit Agreement with JP Morgan Chase Bank ("JP Morgan"), Citibank, NA (“Citibank”), and Wells Fargo Bank, National Association (“Wells Fargo”). During the third quarter of 2020 we amended the terms of the Credit Agreement to extend the maturity date of the original agreement, reduce the aggregate value of the revolving facility, and amend certain covenants. The amended Credit Agreement provides for an aggregate $150.0 million of secured revolving credit facility. The Credit Agreement contains covenants, including covenants relating to maintenance of books and records, financial reporting and notification, compliance with laws, maintenance of properties and insurance, and limitations on guaranties, investments, issuance of debt, lease obligations and capital expenditures, and is secured by virtually all of our assets. The Credit Agreement provides for events of default, including failure to pay any principal or interest when due, failure to perform or observe covenants, bankruptcy or insolvency events and the occurrence of the event has a material adverse effect. We have no other significant credit facilities. As of June 30, 2021, no amounts were outstanding under the Credit Agreement.

    In addition to the customary restrictive covenants listed above, the Credit Agreement also contains financial covenants that require us to maintain a certain leverage ratio and fixed charge coverage ratio, each as defined in the Credit Agreement:

•Leverage Ratio, as defined, to be no higher than 3.25 to 1.00.

•Interest Coverage Ratio, as defined, to be at least 1.75 to 1.00 at all times.

    Pursuant to the terms of the Credit Agreement, the outstanding principal balance will bear interest at either (a) a fluctuating rate per annum equal to the Applicable Rate, as defined in the Credit Agreement, depending on our leverage ratio plus the higher of (i) the federal funds rate plus one-half of one percent per annum; (ii) the prime rate in effect on such a day; and (iii) the LIBOR rate plus one percent, or (b) a fluctuating rate per annum of LIBOR Rate plus the Applicable Rate, which ranges between 2.25% to 3.50%. The Credit Agreement matures on September 25, 2023, at which time all principal amounts outstanding under the Credit Agreement will be due and payable.

As of June 30, 2021, we have discontinued our interest rate swap derivative. Since there are no amounts outstanding under our Credit Agreement and the termination date of the hedge is less than one quarter away with no current plans to draw, we have concluded that the cash flow hedge is not probable of occurring and discontinued the

-14-

hedge relationship. Upon the discontinuation of the hedge relationship, we have reclassified the unrealized gains or losses recorded in accumulated other comprehensive income (“AOCI”) to earnings.

14 - Segment, Customer and Geographic Information

We operate in one reportable segment in which we provide medical device solutions focused on the diagnosis and treatment of central nervous and sensory system disorders for patients of all ages.

End-user customer base includes hospitals, clinics, laboratories, physicians, audiologists, and governmental agencies. Most of our international sales are to distributors who resell products to end users or sub-distributors.

The following tables present revenue by end market and geographic region and long-lived asset information by geographic region. Revenue is based on the destination of the shipments and long-lived assets are based on the physical location of the assets (in thousands):

During the three and six months ended June 30, 2021 and 2020, no single customer and no country outside the United States contributed more than 10% of our consolidated revenue.

15 - Fair Value Measurements

ASC 820 defines fair value, establishes a framework for measuring fair value and expands disclosures about fair value measurements. Fair value is defined under ASC 820 as the exit price associated with the sale of an asset or transfer of a liability in an orderly transaction between market participants at the measurement date. ASC 820 establishes the following three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value:

Level 1 - Quoted prices (unadjusted) in active markets that are accessible at the measurement date for assets or liabilities. The fair value hierarchy gives the highest priority to Level 1 inputs.

Level 2 - Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets and liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.

Level 3 - Unobservable inputs that are used when little or no market data is available. The fair value hierarchy gives the lowest priority to Level 3 inputs.

The following financial instruments are not measured at fair value on our consolidated balance sheet as of June 30, 2021 and December 31, 2020 but require disclosure of their fair values: cash and cash equivalents, accounts receivable, and accounts payable. The carrying value of these financial instruments approximates fair values because of their relatively short maturity.

Information regarding our revenues and long-lived assets in the U.S. and in countries outside the U.S. is contained in Note 14 – Segment, Customer and Geographic Information of our condensed consolidated financial statements included in this report and is incorporated in this section by reference.

Revenue by Product Category

We generate our revenue from sales of Devices and Systems, which are generally non-recurring, and from related Supplies and Services, which are generally recurring. The products that are attributable to these categories are described in our Annual Report on Form 10-K for the year ended December 31, 2020. Revenue from Devices and Systems, Supplies, and Services, as a percent of total revenue for the three and six months ended June 30, 2021 and 2020, is as follows:

	Three Months Ended June 30,				Six Months Ended June 30,
	2021		2020		2021		2020
Devices and Systems	75	%	71	%	75	%	72	%
Supplies	22	%	24	%	22	%	24	%
Services	3	%	5	%	3	%	4	%
Total	100	%	100	%	100	%	100	%

2021 Second Quarter Overview

Our business and operating results are driven in part by worldwide economic conditions. Our revenue is significantly dependent on both capital spending by hospitals in the United States and healthcare spending by ministries of health outside the United States.

We experienced an increase in demand in the United States, Asia Pacific and Europe, during the second quarter compared to the same period in the prior year as recovery from the COVID-19 pandemic continues. Our consolidated revenue for the second quarter ended June 30, 2021 was $116.0 million compared to $84.8 million in the second quarter of the previous year, an increase of $31.2 million.

Our net income was $3.5 million or $0.10 per diluted share in the three months ended June 30, 2021, compared with net loss of $8.9 million or $0.26 per share in the same period in 2020. The increase in net income was the result of higher revenue due to the recovery from impact of COVID-19, in particular for Neuro products, partly offset by higher expenses due to increase in commissions and travel compared to the same period last year as sales activity increased and impact of required paid time-off in 2020 not repeating in 2021.

-17-

COVID-19 Update

Healthcare providers and patients continue to depend on our products and services every day. Our team members and partners are continuing to maintain our supply chain, manufacturing and delivery of our products and services. The health and welfare of our employees, our customers and our partners remain our top priority as we continue our business operations.

We have implemented safeguards in our facilities to protect team members, including social distancing practices, work from home and other measures consistent with specific regulatory requirements and guidance from health authorities. As an essential supplier of healthcare products and services, all of our manufacturing, engineering and customer support functions remain fully operational and will continue to support customers with vital supplies, service and equipment. We will continue to prioritize spending to allow continued investment in products and services that are key elements of our stated strategy for profitable growth in the years ahead.

Impact to our supply chain

Many of our materials are single source and require lengthy qualification periods. Disruptions in our supply chain could negatively impact our ability to produce and supply our finished products. To date, we have experienced some extended lead times and delays in receiving supplies and finished goods. However, we have not yet experienced supply disruptions that are material enough to change our revenue expectations. We are working closely with our suppliers to manage orders and proactively minimize delays in the materials we require to meet our demand.

Liquidity

In the first quarter of 2020 we drew $60.0 million on our credit line as a precaution to ensure we have the necessary capital to continue to reliably serve our customers during an extended period of uncertainty of which $43.0 million was repaid by December 31, 2020. During the third quarter of 2020 we amended our Credit Agreement which extended the maturity date of the original agreement from September 23, 2021 to September 25, 2023, reduced the aggregate revolving credit facility from $225.0 million to $150.0 million, and amended certain covenants. During 2021, we repaid the full outstanding debt balance of $57.0 million under our Credit Agreement and continued to maintain a strong cash position ending the period with $62.5 million in cash.

As a result of the COVID-19 pandemic, some hospitals and clinics delayed payments for products and services and we have worked with our customers to arrange mutually acceptable payment terms during this uncertain time. We have seen revenues and margins improve since the onset of the pandemic. We continue to see our customers adapting to the COVID environment, which we believe will result in increased capital spending and continue to improve our business in 2021. As of the date of this filing, uncertainty continues to exist concerning the impact and duration of the COVID-19 pandemic, including the emergence of variant strains of the virus, such as the Delta variant.

While we believe that we have sufficient liquidity to operate the Company for the foreseeable future should negative economic conditions persist for an extended period of time, we are evaluating additional measures we could take to further enhance our liquidity position.

Government Grants

Various government programs have been announced to provide financial relief for businesses affected by COVID-19 including the CEWS under the COVID-19 Economic Response Plan in Canada. We received $2.9 million for payroll subsidies under CEWS during the three months ended March 31, 2021. Our policy is to account for these subsidies in the same manner as an offset to the expense they relate to in the period in which we are reasonably assured to receive payment. For the three months ended March 31, 2021 we recognized reductions of $0.4 million of cost of sales, $1.3 million of marketing and selling expense, and $1.2 million of research and development expense in the condensed consolidated statements of operations for these subsidies. No payroll subsidies were received or recognized under CEWS in prior periods. As of June 30, 2021 we have collected all amounts recorded and continue to seek additional relief as applicable.

-18-

Impact to fair-value of intangible assets

We have reviewed the assets on our balance sheet, particularly goodwill and significant intangible assets for indications of impairment related to COVID-19 and determined that there are no indicators of impairment at this time. The values of these assets are particularly sensitive to our market cap and the long-term value of their cash flows. If these conditions change significantly, we may need to record an impairment to their value. However, any impairment charges would not require the use of cash and are excluded from the calculation of our debt covenants and, therefore, would not affect our ability to borrow under our existing credit line.

Travel restrictions and use of online technology

The global Natus team is geographically diverse with multiple small locations and hundreds of employees that typically work from home in normal circumstances. We use the latest collaboration technology and have been able to transition to a company-wide work from home model without major interruption. Our manufacturing, distribution and field service operations require physical presence of certain employees as their work requires them to handle our products. In these cases, we have made adjustments to shift size and schedule and limited access to these groups by non-related employees. Our field service technicians are following our customers' requirements for distancing practices but continue to provide service where needed.

Travel restrictions have forced most customer and external partner collaboration to online technology. Using this technology has enabled us to continue operations without incident. However, in-person customer engagement as well as physical presence in laboratory settings is returning and becoming more frequent over the course of 2021.

Application of Critical Accounting Policies

We prepare our financial statements in accordance with accounting principles generally accepted in the United States of America. In so doing, we must often make estimates and use assumptions that can be subjective, and, consequently, our actual results could differ from those estimates. For any given individual estimate or assumption we make, there may also be other estimates or assumptions that are reasonable.

We believe that the following critical accounting policies require the use of significant estimates, assumptions, and judgments:

•Revenue recognition

•Inventory valuation

•Income Taxes

The use of different estimates, assumptions, or judgments could have a material effect on the reported amounts of assets, liabilities, revenue, expenses, and related disclosures as of the date of the financial statements and during the reporting period. These critical accounting policies are described in more detail in our Annual Report on Form 10-K for the year ended December 31, 2020, under Item 7, Management’s Discussion and Analysis of Financial Condition and Results of Operations.

For the three months ended June 30, 2021, Neuro revenue increased by 62% compared to the same period last year driven by higher sales of devices and supplies as the business recovered from the impact of COVID-19 in 2020.

For the three months ended June 30, 2021, Newborn Care revenue decreased by 2% compared to the same period last year due mainly to a decrease in NICVIEW device sales as the same period last year included release of backlog resulting from prior ship hold, partly offset by increased in Eye Imaging devices, Hearing Screening devices and revenue from our agreement with Pediatrix.

-20-

For the three months ended June 30, 2021, Hearing & Balance revenue increased 34% compared to the same period last year due to device and supply sales as the business recovered from the impact of the COVID-19 pandemic in 2020.

For the six months ended June 30, 2021, Neuro revenue increased 28% compared to the same period last year due to recovery from the impact of the COVID-19 pandemic in 2020 in both our domestic and international markets.

For the six months ended June 30, 2021, Newborn Care revenue increased by 2% compared to the same period last year. The increase was due mainly to higher services revenue from our agreement with Pediatrix, higher Hearing Screening device sales, and higher Eye Imaging device sales, partly offset by decreases in Hearing Screening supplies and Phototherapy devices due to lower births and lower services revenue from Neometrics.

For the six months ended June 30, 2021, Hearing & Balance revenue increased by 15% compared to the same period last year as the business recovered from the impact of the COVID-19 pandemic in 2020.

Revenue from domestic sales increased to $70.7 million for the three months ended June 30, 2021 compared to $51.2 million in the three months ended June 30, 2020. The increase was driven by recovery in demand, mainly for our Neuro products, following the impact of the COVID-19 pandemic in the same period last year.

Revenue from international sales increased to $45.2 million for the three months ended June 30, 2021 compared to $33.6 million for the three months ended June 30, 2020. The increase was driven by recovery in demand, mainly for our Neuro and Hearing & Balances products, following the impact of the COVID-19 pandemic in the same period last year.

For the three and six months ended June 30, 2021, gross profit as a percentage of revenue increased 9.5% and 4.4% compared to the same period in the prior year, respectively. The increase was due to higher revenue resulting from recovery from the impact of the COVID-19 pandemic.

Operating Costs

Operating costs consist of (in thousands):

Percentage of revenue	0.1		%	0.7		%	0.1		%	0.8		%

Marketing and Selling

Marketing and selling expenses increased for the three and six months ended June 30, 2021. The increase was primarily driven by higher commissions and travel expenses resulting from increased commercial activity compared to the same periods last year. In addition, the benefit of required paid time-off during the three and six months ended June 30, 2020 was not repeated in the current year.

Research and Development

Research and development expenses decreased slightly during the three and six months ended June 30, 2021 compared to the same period in 2020. The decrease is the result of lower project spend due to timing partly offset by the benefit of required paid-time off during the three and six months ended June 30, 2020 was not repeated in the current year.

General and Administrative

General and administrative expense during the three and six months ended June 30, 2021 increased when compared to the same period in the prior year. This increase was due to higher stock compensation and incentive compensation.

Intangibles Amortization

Intangibles amortization remained flat during the three and six months ended June 30, 2021 as compared to the same period in 2020.

Restructuring

Restructuring expenses decreased during the three and six months ended June 30, 2021 compared to the same period in 2020. The decrease in the three and six months ended June 30, 2021 was primarily driven by lower severance costs and costs incurred as the result of exiting the Peloton business in 2020, which did not recur in 2021.

Other Expense, net

Other expense, net consists of investment income, interest expense, net currency exchange gains and losses, and other miscellaneous income and expense. For the three months ended June 30, 2021 we reported $0.7 million of other expense compared to $0.8 million of other expense for the same period in 2020. The decrease in expense was driven by less interest expense offset by an equity method investment adjustment.

Provision for (Benefit from) Income Tax

Our tax provision for interim periods is determined using an estimated annual effective tax rate, adjusted for discrete events arising in each respective quarter. During each interim period, we update the estimated annual

-22-

effective tax rate which is subject to significant volatility due to several factors, including our ability to accurately predict the income (loss) before provision for income taxes in multiple jurisdictions, the effects of acquisitions, the integration of those acquisitions, and changes in tax law. In circumstances where we are unable to predict income (loss) in multiple jurisdictions, the actual year to date effective tax rate may be the best estimate of the annual effective tax rate for purposes of determining the interim provision for income tax.

We recorded income tax expense of $1.9 million and $2.4 million for the three and six months ended June 30, 2021, respectively. The effective tax rate was 35.4% and 28.8% for the three and six months ended June 30, 2021, respectively. We recorded a benefit from income tax of $3.9 million and $5.0 million for the three and six months ended June 30, 2020, respectively. The effective tax rate was 30.4% and 28.6% for the three and six months ended June 30, 2020, respectively. The increase in the effective tax rate for the three months ended June 30, 2021 compared with the three months ended June 30, 2020, is primarily attributable to changes in distribution of income among jurisdictions with varying tax rates and recording of additional reserves for uncertain tax positions related to a proposed audit assessment received in Denmark. Other significant factors impacting the current period effective tax rate included Federal and California research and development credits, non-deductible executive compensation expenses, and other discrete events.

We recorded one change related to unrecognized tax benefits for the three months ended June 30, 2021 related to a proposed audit assessment received in Denmark. Within the next twelve months, it is possible that the uncertain tax positions may change with a range of approximately zero to $0.2 million. Our tax returns remain open to examination as follows: U.S Federal, 2017 through 2020, U.S. states, 2016 through 2020, and significant foreign jurisdictions, generally 2016 through 2020.

Liquidity and Capital Resources

Liquidity and capital resources consist of (in thousands):

	June 30, 2021		December 31, 2020
Cash and cash equivalents	$	62,494	$	82,082
Working capital	143,236		125,950

	Six Months Ended June 30,
	2021		2020
Net cash provided by operating activities	$	44,096	$	9,612
Net cash used in investing activities	(2,967)		(6,927)
Net cash provided by (used in) financing activities	(57,848)		19,995

We believe that our current cash and cash equivalents and any cash generated from operations will be sufficient to meet our ongoing operating requirements for the foreseeable future.

As of June 30, 2021, we had cash and cash equivalents outside the U.S. in certain of our international subsidiaries of $40.7 million, primarily in Canada and Ireland. We intend to permanently reinvest the cash held by our international subsidiaries except for Excel Tech Corporation and Natus Manufacturing Limited, which we intend to repatriate. A net deferred tax liability has been recorded for the potential future repatriation. If, however, a portion of permanently reinvested funds were needed for and distributed to our operations in the United States, we would be subject to additional U.S. income taxes and foreign withholding taxes depending on facts and circumstances at the time of distribution. The amount of taxes due would depend on the amount and manner of repatriation, as well as the country from which the funds were repatriated.

We have a Credit Agreement with JP Morgan, Citibank, and Wells Fargo. During the third quarter of 2020 we amended the terms of the Credit Agreement to extend the maturity of the original agreement, reduce the aggregate value of the revolving credit facility, and amend certain covenants. The amended Credit Agreement provides for an aggregate $150.0 million of secured revolving credit facility. The Credit Agreement contains covenants, including covenants relating to maintenance of books and records, financial reporting and notification, compliance with laws,

-23-

maintenance of properties and insurance, and limitations on guaranties, investments, issuance of debt, lease obligations and capital expenditures, and is secured by virtually all of our assets. The Credit Agreement provides for events of default, including failure to pay any principal or interest when due, failure to perform or observe covenants, bankruptcy or insolvency events and the occurrence of the event has a material adverse effect. The Credit Agreement matures on September 25, 2023, at which time all principal amounts outstanding under the Credit Agreement will be due and payable. We have no other significant credit facilities. As of June 30, 2021, no amounts were outstanding under the Credit Agreement.

During the six months ended June 30, 2021 cash provided by operating activities of $44.1 million was the result of $5.9 million of net income, non-cash adjustments to net income of $21.7 million which was primarily driven by an adjustment for depreciation and amortization of $14.5 million, and net cash inflows of $16.6 million from changes in operating assets and liabilities primarily driven by reductions in accounts receivable and inventory. Cash used in investing activities during the period was $3.0 million consisting of $2.0 million to acquire other property and equipment and of $1.0 million for purchase of equity method investments. Cash used in financing activities during the six months ended June 30, 2021 was $57.8 million and consisted of repayment on borrowing of $57.0 million, $1.2 million for taxes paid related to net share settlement of equity awards, $0.2 million for principal payments of financing lease liability offset by Employee Stock Purchase Program (“ESPP”) purchases of $0.6 million.

During the six months ended June 30, 2020 cash provided by operating activities of $9.6 million was the result of $12.5 million of net loss, non-cash adjustments to net loss of $21.7 million, and net cash inflows of $0.4 million from changes in operating assets and liabilities. The non-cash adjustment to net loss was primarily driven by depreciation and amortization of $13.7 million. Cash used in investing activities during the period was $6.9 million to acquire other property and equipment. Cash provided by financing activities during the six months ended June 30, 2020 was $20.0 million and consisted of proceeds from borrowing of $60.0 million and Employee Stock Purchase Program (“ESPP”) purchases of $0.7 million offset by repayment on borrowing of $28.0 million, $10.5 million for repurchases of common stock under our share repurchase program, $1.9 million for taxes paid related to net share settlement of equity awards, and $0.2 million for principal payments of financing lease liability.

Our future liquidity and capital requirements will depend on numerous factors, including the: 

•Extent to which we make acquisitions;

•Amount and timing of revenue;

•Extent to which our existing and new products gain market acceptance;

•Cost and timing of product development efforts and the success of these development efforts;

•Cost and timing of marketing and selling activities; and

•Availability of borrowings under line of credit arrangements and the availability of other means of financing.

Commitments and Contingencies

In the normal course of business, we enter into obligations and commitments that require future contractual payments. The commitments result primarily from firm, non-cancellable purchase orders placed with contract vendors that manufacture some of the components used in our medical devices and related disposable supply products, as well as commitments for leased office space, and bank debt. The following table summarizes our

-24-

contractual obligations and commercial commitments as of June 30, 2021 (in thousands):

			Payments Due by Period
	Total		Less than 1 Year		1-3 Years		3-5 Years		More than 5 Years
Unconditional purchase obligations	$	56,709	$	52,188	$	4,521	$	—	$	—
Interest payments	2,108		978		1,130		—
Repatriation tax	5,677		170		3,212		2,295		—
Total	$	64,494	$	53,336	$	8,863	$	2,295	$	—

Purchase obligations are defined as agreements to purchase goods or services that are enforceable and legally binding. Included in the purchase obligations category above are obligations related to purchase orders for inventory purchases under our standard terms and conditions and under negotiated agreements with vendors. We expect to receive consideration (products or services) for these purchase obligations. The purchase obligation amounts do not represent all anticipated purchases in the future but represent only those items for which we are contractually obligated. The table above does not include obligations under employment agreements for services rendered in the ordinary course of business.

The interest payments noted above are an estimate of expected interest payments but could vary materially based on the timing of future loan draws and payments. See Note 13 to the unaudited Condensed Consolidated Financial Statements for additional discussion on our debt and credit arrangements.

We are not able to reasonably estimate the timing of any potential payments for uncertain tax positions under ASC 740, Accounting for Uncertainty in Income Taxes—an interpretation of FASB Statement 109. As a result, the preceding table excludes any potential future payments related to our ASC 740 liability for uncertain tax positions. See Note 18 in our Annual Report filed on Form 10-K for the year ended December 31, 2020 for further discussion on income taxes and repatriation tax.

ITEM 4.    Controls and Procedures

Evaluation of Disclosure Controls and Procedures

Under the rules of the Securities and Exchange Commission, “disclosure controls and procedures” are controls and other procedures that are designed to ensure that information required to be disclosed in the reports that we file or submit under the Securities Exchange Act of 1934 is recorded, processed, summarized and reported within the time periods specified in the rules and forms of the Securities and Exchange Commission. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by us in our reports that we file or submit under the Securities Exchange Act of 1934 is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure.

Our management, including our chief executive officer and chief financial officer, does not expect that our disclosure controls and procedures or our internal control over financial reporting will prevent all errors and all fraud due to inherent limitations of internal controls. Because of such limitations, there is a risk that material misstatements will not be prevented or detected on a timely basis by internal control over financial reporting. However, these inherent limitations are known features of the financial reporting process. Therefore, it is possible to design into the process safeguards to reduce, though not eliminate, this risk.

Our management, with the participation of our chief executive officer and our chief financial officer, has evaluated the effectiveness of our disclosure controls and procedures as of the end of the period covered by this report. Based on that evaluation, our management, including our chief executive officer and chief financial officer, has concluded that our disclosure controls and procedures were effective at a reasonable assurance level as of June 30, 2021.

Changes in Internal Control over Financial Reporting

There were no changes in the Company's internal control over financial reporting during the second quarter of 2021, which were identified in connection with management's evaluation required by paragraph (d) of Rules 13a-15 and 15d-15 under the Exchange Act, that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II.    OTHER INFORMATION

ITEM 1.    Legal Proceedings

We currently are, and may from time to time become, a party to various other legal proceedings or claims that arise in the ordinary course of business. Our management reviews these matters if and when they arise and believes that the resolution of any such matters currently known will not have a material effect on our results of operations or financial position.

ITEM 1A.    Risk Factors

PURSUANT TO TITLE 18, UNITED STATES CODE, SECTION 1350, AS ADOPTED

Fair Value Disclosures [Abstract]

Fair Value Measurements

Fair Value Measurements

ASC 820 defines fair value, establishes a framework for measuring fair value and expands disclosures about fair value measurements. Fair value is defined under ASC 820 as the exit price associated with the sale of an asset or transfer of a liability in an orderly transaction between market participants at the measurement date. ASC 820 establishes the following three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value:

Level 1 - Quoted prices (unadjusted) in active markets that are accessible at the measurement date for assets or liabilities. The fair value hierarchy gives the highest priority to Level 1 inputs.

Level 2 - Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets and liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.

Level 3 - Unobservable inputs that are used when little or no market data is available. The fair value hierarchy gives the lowest priority to Level 3 inputs.

The following financial instruments are not measured at fair value on our consolidated balance sheet as of June 30, 2021 and December 31, 2020 but require disclosure of their fair values: cash and cash equivalents, accounts receivable, and accounts payable. The carrying value of these financial instruments approximates fair values because of their relatively short maturity.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Basis of Presentation

Basis of Presentation and Significant Accounting Policies

The accompanying interim condensed consolidated financial statements of Natus Medical Incorporated (“we,” “us,” or “our”) have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”). Except where noted below within Note 1, the accounting policies followed in the preparation of the interim condensed consolidated financial statements are consistent in all material respects with those presented in Note 1 to the consolidated financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2020.

Interim financial reports are prepared in accordance with the rules and regulations of the Securities and Exchange Commission; accordingly, the reports do not include all of the information and notes required by GAAP for annual financial statements. The interim financial information is unaudited, and reflects all normal adjustments that are, in the opinion of management, necessary for the fair presentation of our financial position, results of operations, and cash flows for the interim periods presented. We have made certain reclassifications to the prior period to conform to current period presentation. The consolidated balance sheet as of December 31, 2020 was derived from audited financial statements but does not include all disclosures required by GAAP. The accompanying financial statements should be read in conjunction with the financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2020.

Operating results for the three and six months ended June 30, 2021 are not necessarily indicative of the results that may be expected for the year ending December 31, 2021. The accompanying condensed consolidated financial statements include our accounts and our wholly owned subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation.

Impact of COVID-19 on Our Financial Statements

On March 11, 2020, the World Health Organization declared COVID-19 a global pandemic and recommended extensive containment and mitigation measures worldwide. Since that time, we established what we believe are the necessary protocols to operate safely in our manufacturing facilities, virtually engage with customers and suppliers and work remotely when possible. Our businesses continue to recover as sales in our Neuro and Newborn Care business have returned to pre-pandemic levels. Sales for our Hearing & Balance business, which are more concentrated in Europe have partially recovered, but remain below pre-pandemic levels.

Various government programs have been established to provide financial relief for businesses affected by COVID-19 including the Canada Emergency Wage Subsidy ("CEWS") and Canada Emergency Rent Subsidy ("CERS") under the COVID-19 Economic Response Plan in Canada. We received $2.9 million for payroll subsidies under CEWS during the three months ended March 31, 2021. Our policy is to account for these subsidies in the same manner as an offset to the expense they relate to in the period in which we are reasonably assured to receive payment. For the six months ended June 30, 2021 we recognized reductions of $0.4 million in cost of sales, $1.3 million in marketing and selling expense, and $1.2 million in research and development expense in the condensed consolidated statements of operations for these subsidies. No payroll subsidies were received or recognized under CEWS in prior periods. As of June 30, 2021 we have collected all amounts recorded and continue to seek additional relief as applicable.

We have assessed various accounting estimates and other matters, including those that require consideration of forecasted financial information, in context of the unknown future impacts of COVID-19 using information that is reasonably available to us at this time. The accounting estimates and other matters we assessed include, but were not limited to, our allowance for doubtful accounts, inventory and warranty reserves, stock-based compensation, goodwill and other long-lived assets, financial assets, valuation allowances for tax assets and revenue recognition. While based on our current assessment of these estimates there was not a material impact to our consolidated financial statements as of and for the three and six months ended June 30, 2021, as additional information becomes available to us, our future assessment of these estimates, including our expectations at the time regarding the

duration, scope and severity of the pandemic, as well as other factors, could materially and adversely impact our consolidated financial statements in future reporting periods.

Revenue from Contract with Customer [Abstract]

Revenue

Revenue

    Unbilled accounts receivable (“AR”) for the periods presented primarily represent the difference between revenue recognized based on the relative selling price of the related performance obligations and the contractual billing terms in the arrangements. Deferred revenue for the periods presented primarily relates to extended service contracts, installation, and training, for which the service fees are billed in advance. The associated deferred revenue is generally recognized ratably over the extended service period or when installation and training are complete.

The following table summarizes the changes in the unbilled AR and deferred revenue balances for the six months ended June 30, 2021 (in thousands):

Unbilled AR, December 31, 2020	$	1,925
Additions	62
Transferred to trade receivable	(61)
Unbilled AR, June 30, 2021	$	1,926

Deferred revenue, December 31, 2020	$	25,723
Additions	17,144
Revenue recognized	(13,723)
Deferred revenue, June 30, 2021	$	29,144

    At June 30, 2021, the short-term portion of deferred revenue of $24.4 million and the long-term portion of $4.7 million are included in deferred revenue and other long-term liabilities, respectively, in the consolidated balance sheet. As of June 30, 2021, we expect to recognize revenue associated with deferred revenue of approximately $15.9 million in 2021, $10.1 million in 2022, $1.7 million in 2023, $1.0 million in 2024, and $0.4 million thereafter.

Allowance for Doubtful Accounts

Allowance for Doubtful Accounts

We estimate the lifetime allowance for doubtful, potentially uncollectible, accounts receivable upon their inception based on historical collection experience within the markets in which we operate, customer-specific information such as bankruptcy filings or customer liquidity problems, current conditions, and reasonable and supportable forecasts about the future.

Our allowance for doubtful accounts is presented as a reduction to accounts receivable on our consolidated balance sheet. When all internal efforts have been exhausted to collect the receivable, it is written off and relieved from the reserve.

The details of activity in allowance for doubtful accounts are as follows (in thousands):

Product Warranties Disclosures [Abstract]

Reserve for Product Warranties

Reserve for Product Warranties

We provide a warranty for products that is generally one year in length. In some cases, regulations may require us to provide repair or remediation beyond the typical warranty period. If any of the products contain defects, we may incur additional repair and remediation costs. Service, repair and calibration services are provided by a combination of our owned facilities and vendors on a contract basis.

We accrue estimated product warranty costs at the time of sale based on historical experience. A warranty reserve is included in accrued liabilities for the expected future costs of servicing products. Additions to the reserve are based on management’s best estimate of probable liability. We consider a combination of factors including material and labor costs, regulatory requirements, and other judgments in determining the amount of the reserve. The reserve is reduced as costs are incurred to honor existing warranty and regulatory obligations.

As of June 30, 2021, we have accrued $4.8 million for product related warranties. Our estimate of these costs is primarily based upon the number of units outstanding that may require repair and costs associated with shipping.

The details of activity in the warranty reserve are as follows (in thousands):

	Three Months Ended June 30,				Six Months Ended June 30,
	2021		2020		2021		2020

Our estimate of future product warranty costs may vary from actual product warranty costs, and any variance from estimates could impact our cost of sales, operating profits and results of operations.

Income Tax Disclosure [Abstract]

Income Taxes

Income Taxes

Our tax provision for interim periods is determined using an estimated annual effective tax rate, adjusted for discrete events arising in each respective quarter. During each interim period, we update the estimated annual effective tax rate which is subject to significant volatility due to several factors, including our ability to accurately predict the income (loss) before provision for income taxes in multiple jurisdictions, the effects of acquisitions, the integration of those acquisitions, and changes in tax law. In circumstances where we are unable to predict income (loss) in multiple jurisdictions, the actual year to date effective tax rate may be the best estimate of the annual effective tax rate for purposes of determining the interim provision for income tax.

We recorded income tax expense of $1.9 million and $2.4 million for the three and six months ended June 30, 2021, respectively. The effective tax rate was 35.4% and 28.8% for the three and six months ended June 30, 2021, respectively. We recorded a benefit from income tax of $3.9 million and $5.0 million for the three and six months ended June 30, 2020, respectively. The effective tax rate was 30.4% and 28.6% for the three and six months ended June 30, 2020, respectively. The increase in the effective tax rate for the three months ended June 30, 2021 compared with the three months ended June 30, 2020, is primarily attributable to changes in distribution of income among jurisdictions with varying tax rates and recording of additional reserves for uncertain tax positions related to a proposed audit assessment received in Denmark. Other significant factors impacting the current period effective tax rate included Federal and California research and development credits, non-deductible executive compensation expenses, and other discrete events.

We recorded one change related to unrecognized tax benefits for the three months ended June 30, 2021 related to a proposed audit assessment received in Denmark. Within the next twelve months, it is possible that the uncertain tax positions may change with a range of approximately zero to $0.2 million. Our tax returns remain open to examination as follows: U.S Federal, 2017 through 2020, U.S. states, 2016 through 2020, and significant foreign jurisdictions, generally 2016 through 2020.

Debt and Credit Arrangements

Debt and Credit Arrangements

    We have a Credit Agreement with JP Morgan Chase Bank ("JP Morgan"), Citibank, NA (“Citibank”), and Wells Fargo Bank, National Association (“Wells Fargo”). During the third quarter of 2020 we amended the terms of the Credit Agreement to extend the maturity date of the original agreement, reduce the aggregate value of the revolving facility, and amend certain covenants. The amended Credit Agreement provides for an aggregate $150.0 million of secured revolving credit facility. The Credit Agreement contains covenants, including covenants relating to maintenance of books and records, financial reporting and notification, compliance with laws, maintenance of properties and insurance, and limitations on guaranties, investments, issuance of debt, lease obligations and capital expenditures, and is secured by virtually all of our assets. The Credit Agreement provides for events of default, including failure to pay any principal or interest when due, failure to perform or observe covenants, bankruptcy or insolvency events and the occurrence of the event has a material adverse effect. We have no other significant credit facilities. As of June 30, 2021, no amounts were outstanding under the Credit Agreement.

    In addition to the customary restrictive covenants listed above, the Credit Agreement also contains financial covenants that require us to maintain a certain leverage ratio and fixed charge coverage ratio, each as defined in the Credit Agreement:

•Leverage Ratio, as defined, to be no higher than 3.25 to 1.00.

•Interest Coverage Ratio, as defined, to be at least 1.75 to 1.00 at all times.

    Pursuant to the terms of the Credit Agreement, the outstanding principal balance will bear interest at either (a) a fluctuating rate per annum equal to the Applicable Rate, as defined in the Credit Agreement, depending on our leverage ratio plus the higher of (i) the federal funds rate plus one-half of one percent per annum; (ii) the prime rate in effect on such a day; and (iii) the LIBOR rate plus one percent, or (b) a fluctuating rate per annum of LIBOR Rate plus the Applicable Rate, which ranges between 2.25% to 3.50%. The Credit Agreement matures on September 25, 2023, at which time all principal amounts outstanding under the Credit Agreement will be due and payable.

As of June 30, 2021, we have discontinued our interest rate swap derivative. Since there are no amounts outstanding under our Credit Agreement and the termination date of the hedge is less than one quarter away with no current plans to draw, we have concluded that the cash flow hedge is not probable of occurring and discontinued the

hedge relationship. Upon the discontinuation of the hedge relationship, we have reclassified the unrealized gains or losses recorded in accumulated other comprehensive income (“AOCI”) to earnings.
