NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (unaudited)

1 - Basis of Presentation

The accompanying interim condensed consolidated financial statements of Natus Medical Incorporated (“Natus,” “we,” “us,” “our,” or the “Company”) have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”). 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 the Company’s Annual Report on Form 10-K for the year ended December 31, 2014.

Interim financial reports are prepared in accordance with the rules and regulations of the Securities and Exchange Commission; accordingly, they do not include all of the information and notes required by GAAP for annual financial statements. The interim financial information is unaudited, and except for the prior period correction of errors disclosed below, 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. The consolidated balance sheet as of December 31, 2014 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 the Company’s Annual Report on Form 10-K for the year ended December 31, 2014. We have made certain reclassifications to the prior period to conform to current period presentation.

Operating results for the three months ended March 31, 2015 are not necessarily indicative of the results that may be expected for the year ending December 31, 2015. The accompanying condensed consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation.

Recent Accounting Pronouncements

In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2014-09, Revenue from Contracts with Customers (Topic 606). ASU 2014-09 requires revenue recognition to depict the transfer of goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. ASU 2014-09 sets forth a new revenue recognition model that requires identifying the contract, identifying the performance obligations, determining the transaction price, allocating the transaction price to performance obligations and recognizing the revenue upon satisfaction of performance obligations. The Company is currently evaluating the impact of ASU 2014-09, which is effective for the Company in our fiscal year ending December 31, 2017.

2 - Business Combinations

Global Neuro-Diagnostics

The Company acquired Global Neuro-Diagnostics ("GND") through an equity purchase on January 23, 2015. GND's service offers patients a more convenient way to complete routine EEG and video EEG testing which can be performed at the home, hospital or physician's office. The service also provides comprehensive reporting and support to the physician. The cash consideration for GND was $11.4 million. The purchase agreement also included an earn-out condition which the Company estimates to be $3.3 million. This earn-out is contingent upon GND achieving certain revenue milestones from 2015 to 2017.

Valuing intangible assets required us to make significant estimates that will be adjusted in the future; consequently, the purchase price allocation is considered preliminary. Final determination of the value of intangible assets is expected during the second quarter of 2015 and will result in an adjustment to the preliminary purchase price allocation, with an offsetting adjustment to goodwill. Pro forma financial information for the GND acquisition is not presented as it is not considered material.

NicView

On January 2, 2015, the Company purchased the assets of NicView for cash consideration of $1.1 million. NicView provides streaming video for families with babies in the neonatal intensive care unit.

Hearing Screening as a Service

In the first quarter of 2014, the Company entered into two asset purchase agreements for companies in the newborn hearing screening services market for cash consideration of $2.6 million. The purchase agreements also included an earn-out condition which is contingent upon annual revenue growth through 2016. This earn-out condition is currently estimated at $0.8 million. Both acquisitions support the Company’s objective to enter this market that complements our newborn hearing screening device business. This hearing screening services business operates under the name Peloton.

8 - Reserve for Product Warranties

We provide a warranty on all medical device products that is generally one year in length. We also sell extended service agreements on our medical device products that are generally over one year in length. Service for domestic customers is provided by Company-owned service centers that perform all service, repair, and calibration services. Service for international customers is provided by a combination of Company-owned facilities and vendors on a contract basis.

We have accrued a warranty reserve, included in accrued liabilities on the accompanying condensed consolidated balance sheets, for the expected future costs of servicing products during the initial warranty period. We base the liability on actual warranty costs incurred to service those products. Additions to the reserve are based on a combination of factors including the percentage of service department labor applied to warranty repairs, as well as actual service department costs, and other judgments, such as the degree to which the product incorporates new technology. The reserve is reduced as costs are incurred to honor existing warranty obligations.

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

	Three Months Ended March 31,

and our methods for determining grant-date fair value of the awards were consistent with those described in the consolidated financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2014.

11 - Income Taxes

Provision for Income Tax Expense

Our effective tax rate (ETR) (provision for income taxes divided by pretax income) for the three months ended March 31, 2015 and 2014 was 31.3% and 30.4%, respectively. Our year-to-date results reflect the projected fiscal year ETR, as adjusted for the impact of any discrete items. Our ETR for the three months ended March 31, 2015 includes the discrete tax impact of the forgiveness of an intercompany loan between the U.S. parent company and its Argentinian subsidiary which increased our ETR by 3.7%. The discrete item recognized during the three months ended March 31, 2014 was not material to the ETR. The decrease in our ETR excluding the impact of discrete items, is due to forecasted shifts in the geographical mix of income. Our ETR for the three months ended March 31, 2015 and 2014 differed from statutory tax rates primarily because of profits taxed in foreign jurisdictions with lower tax rates than the statutory rate.

We recorded a net tax expense of $143,000 of unrecognized tax benefits for the three months ended March 31, 2015. Within the next twelve months, it is possible our uncertain tax benefit may change within a range of approximately zero to $800,000.Our tax returns remain open to examination as follows: U.S. Federal, 2011 through 2013, U.S. States 2010 through 2013 and significant foreign jurisdictions, 2010 through 2013.

12 - Restructuring Reserves

The Company has historically incurred an ongoing level of restructuring-type activities to maintain a competitive cost structure, including manufacturing and workforce optimization resulting from acquisitions.

The balance of the restructuring reserve is included in accrued liabilities on the accompanying condensed consolidated balance sheets. Employee termination benefits are included as a part of restructuring expenses.

We operate in one reportable segment in which we provide healthcare products used for the screening, detection, treatment, monitoring and tracking of common medical ailments.

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

14 - 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 Company does not have any financial assets or liabilities measured at fair value on a recurring basis.

The following financial instruments are not measured at fair value on the Company’s consolidated balance sheet as of March 31, 2015 and December 31, 2014, but require disclosure of their fair values: cash and cash equivalents, accounts receivable, accounts payable, and accrued liabilities.

In the third quarter of 2014 the Company listed its facility in Mundelein, Illinois for sale. This asset was measured at fair value less cost to sell as of September 30, 2014 based on market price and is classified as a Level 2 asset. The book value of this asset on June 30, 2014 was $3.6 million. We expensed $2.2 million during the third quarter 2014 for this impairment. As of March 31, 2015 we are carrying the asset as held for sale in other current assets on the balance sheet at a value of $1.4 million.

-12-

The Company also has contingent consideration associated with earn-outs from acquisitions. Contingent consideration liabilities are classified as Level 3 liabilities, as the Company uses unobservable inputs to value them, which is a probability-based income approach. Subsequent changes in the fair value of contingent consideration liabilities are recorded within the Company's income statement as an operating expense.

	December 31, 2014		Additions		Payments		March 31, 2015
Liabilities:
Contingent consideration	$	812	$	3,319	$	—	$	4,131
Total	$	812	$	3,319	$	—	$	4,131

As presented in the table above, the significant unobservable inputs used in the fair value measurement of contingent consideration related to the acquisitions are annualized revenue forecasts developed by the Company’s management and the probability of achievement of those revenue forecasts. Significant increases (decreases) in these unobservable inputs in isolation would result in a significantly lower (higher) fair value measurement.

15 - Immaterial Corrections to Prior Period Financial Statements

Certain amounts previously reported in the consolidated statements of income and statements of cash flows for the three months ended March 31, 2014 have been restated to reflect the correction of an immaterial error as disclosed in the Company’s Annual Report on Form 10-K for the year ended December 31, 2014. The error related to the amount of manufacturing labor and overhead applied to inventory. We believe the effects of the error are not material to our consolidated financial statements.

A summary of the effects of the correction of this error on our consolidated financial statements for the three months ended March 31, 2014 is presented in the table below (in thousands, except per share data):

	March 31, 2014

ITEM 2.    Management’s Discussion and Analysis of Financial Condition and Results of Operations

Overview

The following Management’s Discussion and Analysis of Financial Condition and Results of Operations (“MD&A”) supplements the MD&A in the Annual Report on Form 10-K for the year ended December 31, 2014 of Natus Medical Incorporated. MD&A should be read in conjunction with our condensed consolidated financial statements and accompanying footnotes, the risk factors referred to in Part II, Item 1A of this report, our Annual Report filed on Form 10-K for the year ended December 31, 2014 and the cautionary information regarding forward-looking statements at the end of this section.

Our Business

Natus is a leading provider of healthcare products used for the screening, detection, treatment, monitoring and tracking of common medical ailments in newborn care, hearing impairment, neurological dysfunction, epilepsy, sleep disorders, and balance and mobility disorders.

We have completed a number of acquisitions since 2003, consisting of either the purchase of a company, substantially all of the assets of a company, or individual products or product lines. Our most recent significant acquisition was Grass in 2013. In 2015 we completed two acquisitions, NicView and GND. We expect to continue to pursue opportunities to acquire other businesses in the future.

End Markets

Our products address two primary end markets:

• Neurology - Includes products and services for diagnostic electroencephalography and long term monitoring, Intensive Care Unit monitoring, electromyography, sleep analysis or polysomnography, intra-operative monitoring, and diagnostic and monitoring transcranial doppler ultrasound technology.

• Newborn Care - Includes products and services for newborn care including hearing screening, brain injury, thermoregulation, jaundice management, and various disposable products, as well as products for diagnostic hearing assessment for children through adult populations, and products to diagnose and assist in treating balance and mobility disorders.

Segment and Geographic Information

We operate in one reportable segment, which we have presented as the aggregation of our neurology and newborn care product families. Within this reportable segment we are organized on the basis of the healthcare products and services we provide which are used for the screening, detection, treatment, monitoring and tracking of common medical ailments in newborn care, hearing impairment, neurological dysfunction, epilepsy, and sleep disorders.

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

Information regarding our sales and long-lived assets in the U.S. and in countries outside the U.S. is contained in Note 13 – Segment, Customer and Geographic Information of our condensed consolidated financial statements included in this report and is incorporated in this section by this 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, 2014. Revenue from Devices

-14-

and Systems, Supplies and Services, as a percent of total revenue for the three months ended March 31, 2015 and 2014 is as follows:

	Three Months Ended March 31,
	2015		2014
Devices and Systems	65	%	67	%
Supplies	31	%	31	%
Services	4	%	2	%
Total	100	%	100	%

During the three months ended March 31, 2015 and 2014, no single customer or foreign country contributed to more than 10% of revenue.

2015First Quarter Overview

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

Our consolidated revenue increased $3.8 million in the first quarter ended March 31, 2015 to $89.4 million compared to $85.6 million in the first quarter of the previous year. Our revenue increases were primarily in the United States market driven by the strength of sales and recent acquisitions in our Newborn Care business.

Net income was $8.6 million or $0.26 per diluted share in the three months ended March 31, 2015, compared with net income of $6.8 million or $0.21 per diluted share in the same period in 2014. An increase to 59.9% from 59.1% in gross profit percentage for the first quarter of 2015 compared to the same period in 2014 was primarily the result of ongoing cost reduction initiatives.

Application of Critical Accounting Policies

We prepare our financial statements in accordance with accounting principles generally accepted in the United States of America (“GAAP”). 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 carried at the lower of cost or market value

• Carrying value of intangible assets and goodwill

• Liability for product warranties

• Share-based compensation

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, 2014, under Item 7, Management’s Discussion and Analysis of Financial Condition and Results of Operations. There have been no changes to these policies during the three months ended March 31, 2015.

Revenues

The following table shows revenue by products during the three months ended March 31, 2015 and March 31, 2014 in thousands.

	Three Months Ended March 31,
	2015		2014		Change
Neurology
Devices and Systems	$	40,115	$	42,260	(5	)%
Supplies	14,878		14,226		5	%
Services	1,294		—		—	%
Total Neurology	56,287		56,486		—	%

Total Newborn Care	33,108		29,138		14	%
Total Revenue	$	89,395	$	85,624	4	%

For the three months ended March 31, 2015, Neurology revenue was flat compared to the same quarter last year. Growth in our domestic market was offset by a decline in revenue from international markets due mainly to weakness of the Euro to the US Dollar. Revenue from sales of Devices and Systems declined 5%, driven mainly by the exchange rate impact to European sales. The decline in Devices and Systems revenue was partially offset by a growth in Supplies and Services revenue, including revenues resulting from the January 2015 acquisition of Global Neuro-Diagnostics which are included in Neurology Services.

-16-

For the three months ended March 31, 2015, Newborn Care revenue increased by 14% compared to the same quarter last year. Geographically, the increase is primarily in our domestic market. Revenue from Devices and Systems increased 20% compared to the same period in 2014. This increase was primarily related to the introduction of two new products in the hearing and phototherapy market segments and entering the video streaming market with the January 2015 acquisition of NicView. Revenue from Services increased by 59% compared to the same period in 2014 due to the growth of Peloton, our hearing screening service initiative launched in the first quarter 2014.

No single customer accounted for more than 10% of our revenue in the first quarter of either 2015 or 2014. Revenue from domestic sales increased 12.9% to $54.6 million for the three months ended March 31, 2015 from $48.3 million in the first quarter of 2014. This increase was primarily driven by our Newborn Care business as discussed above. Revenue from international sales decreased6.6% to $34.8 million for the three months ended March 31, 2015 compared to $37.3 million in the first quarter of 2014. The decrease in international revenue was driven by the weakness of the Euro to the US Dollar.

Cost of Revenue and Gross Profit

Cost of revenue and gross profit consists of (in thousands):

	Three Months Ended March 31,
	2015			2014
Revenue	$	89,395		$	85,624
Cost of revenue	35,105			33,981
Intangibles amortization	682			1,046
Gross profit	53,608			50,597
Gross profit percentage	59.9		%	59.1		%

For the three months ended March 31, 2015, our gross profit as a percentage of sales increased by 0.9% compared to the same period of the prior year. This increase in gross profit was driven by higher domestic revenues which generally have higher gross margins than international sales, as well as cost reduction initiatives which are resulting in higher margins primarily in Neurology devices.

Operating Costs

Operating costs consist of (in thousands):

	Three Months Ended March 31,
	2015			2014
Marketing and selling	$	20,742		$	20,630
Percentage of revenue	23.2		%	24.1		%
Research and development	$	6,857		$	7,177
Percentage of revenue	7.7		%	8.4		%
General and administrative	$	11,552		$	11,729
Percentage of revenue	12.9		%	13.7		%
Intangibles amortization	$	955		$	1,136
Percentage of revenue	1.1		%	1.3		%
Restructuring	$	156		$	538
Percentage of revenue	0.2		%	0.6		%

-17-

Marketing and Selling

Marketing and selling expenses were flat during three months ended March 31, 2015 as compared to the same period in 2014. We experienced an increase in spending in our Newborn Care business relative to the increase in Newborn Care revenue during the quarter. This was offset by a reduction in expense related to cost cutting initiatives implemented in 2014.

Research and Development

Research and development expenses decreased slightly during the three months ended March 31, 2015 as compared to the same period in 2014. This decrease is attributable to a reduction in information technology overhead allocation.

General and Administrative

General and administrative expense decreased during the three months ended March 31, 2015 as compared to the same period in 2014. This decrease can be attributed to an overall reduction in spending relating to restructuring activities implemented in 2014.

Intangibles Amortization

Intangibles amortization decreased during the three months ended March 31, 2015 as compared to the same period in 2014. This slight decrease is related to intangible asset reconciliations completed during 2014.

Restructuring

Restructuring expenses decreased during the three months ended March 31, 2015 as compared to the same period in 2014. During the first quarter of 2014 we incurred higher expenses related to severance of higher paid employees.

Other Income (Expense), net

Other income (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 March 31, 2015 we reported other expense of $0.8 million compared to other income of $0.3 million for the same period in 2014. This change was driven by an increase in net currency exchange losses driven by the weakness of the Euro.

Provision for Income Tax

Our effective tax rate (ETR) (provision for income taxes divided by pretax income) for the three months ended March 31, 2015 and 2014 was 31.3% and 30.4%, respectively. Our year-to-date results reflect the projected fiscal year ETR, as adjusted for the impact of any discrete items. Our ETR for the three months ended March 31, 2015 includes the discrete tax impact of the forgiveness of an intercompany loan between the U.S. parent company and its Argentinian subsidiary which increased our ETR by 3.7%. The discrete item recognized during the three months ended March 31, 2014 was not material to the ETR. The decrease in our ETR excluding the impact of discrete items, is due to forecasted shifts in the geographical mix of income. Our ETR for the three months ended March 31, 2015 and 2014, differed from statutory tax rates primarily because of profits taxed in foreign jurisdictions with lower tax rates than the statutory rate.

We recorded a net tax expense of $143,000 of unrecognized tax benefits for the three months ended March 31, 2015. Within the next twelve months, it is possible our uncertain tax benefit may change within a range of approximately zero to $800,000.Our tax returns remain open to examination as follows: U.S. Federal, 2011 through 2013, U.S. States 2010 through 2013 and significant foreign jurisdictions, 2010 through 2013.

Liquidity and Capital Resources

Liquidity and capital resources consist of (in thousands):

	March 31, 2015		December 31, 2014
Cash and cash equivalents	$	66,999	$	66,558
Working capital	146,850		148,665

	Three Months Ended March 31,
	2015			2014
Net cash provided by operating activities	$	13,812		$	5,684
Net cash used in investing activities	(13,477		)	(5,766		)
Net cash provided by financing activities	601			3,415

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 March 31, 2015, we had cash and cash equivalents outside the U.S. in certain of our foreign operations of $51.8 million. We intend to permanently reinvest the cash held by our foreign subsidiaries. If, however, a portion of these 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. The amount of taxes due would depend on the amount and manner of repatriation, as well as the location from where the funds were repatriated.

At March 31, 2015, we had a $25 million revolving credit line with Wells Fargo. The credit line is fully available under the credit agreement. The credit facility contains covenants, including covenants relating to liquidity and other financial measurements, and provides for events of default, including failure to pay any interest when due, failure to perform or observe covenants, bankruptcy or insolvency events, and the occurrence of a material adverse effect, and restricts our ability to pay dividends. We have granted Wells Fargo a security interest in substantially all of our assets. We have no other significant credit facilities.

During the three months ended March 31, 2015 cash provided by operating activities of $13.8 million was the result of $8.6 million of net income, non-cash adjustments to net income of $4.8 million, and net cash inflows of $0.4 million from changes in operating assets and liabilities. Cash used in investing activities during the period was $13.5 million and consisted primarily of cash used in the acquisition of GND for $11.4 million and NicView for $1.1 million. Cash used to acquire property and equipment was $1.4 million. Cash provided by financing activities during the three months ended March 31, 2015 was $0.6 million and consisted of proceeds from stock option exercises and ESPP purchases and their related tax benefits of $2.4 million, offset by $1.3 million for repurchases of shares under the Company’s share repurchase program, and $0.5 million for tax payments to settle employee liability related to stock.

During the three months ended March 31, 2014 cash provided by operating activities of $5.7 million was the result of $6.8 million of net income, non-cash adjustments to net income of $8.5 million, and net cash inflows of $4.6 million from changes in operating assets and liabilities. Cash used in investing activities during the period was $5.8 million and consisted of cash used to acquire Tender Touch and HHC of $2.5 million, purchase accounting adjustments of $2.4 million related to the Grass acquisition, and cash used to acquire property and equipment and intangible assets of $0.8 million. Cash provided by financing activities during the three months ended March 31, 2014 was $3.4 million and consisted primarily of ESPP purchases and their related tax benefits of $8.5 million offset by repayment of long term debt of $5.1 million.

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

-19-

• 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, noncancellable 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, manufacturing, and warehouse facilities.

There are no material changes to the table of contractual obligations presented in Item 7, Management’s Discussion and Analysis of Financial Condition and Results of Operations, of our Annual Report on Form 10-K for the year ended December 31, 2014.

Off Balance Sheet Arrangements

Under our bylaws, we have agreed to indemnify our officers and directors for certain events or occurrences arising as a result of the officer or director’s serving in such capacity. We have a directors and officers’ liability insurance policy that limits our exposure and enables us to recover a portion of any future amounts paid resulting from the indemnification of our officers and directors. In addition, we enter into indemnification agreements with other parties in the ordinary course of business. In some cases we have obtained liability insurance providing coverage that limits our exposure for these other indemnified matters. We have not incurred material costs to defend lawsuits or settle claims related to these indemnification agreements. We believe the estimated fair value of these indemnification agreements is minimal and have not recorded a liability for these agreements. During the three months ended March 31, 2015, we had no other off-balance sheet arrangements that had, or are reasonably likely to have, a material effect on our consolidated financial condition, results of operations, or liquidity.

Recent Accounting Pronouncements

See Note 1 to our Condensed Consolidated Financial Statements for a discussion of new accounting pronouncements that affect us.

Cautionary Information Regarding Forward Looking Statements

This report contains forward-looking statements within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934 about Natus Medical Incorporated. These statements include, among other things, statements concerning our expectations, beliefs, plans, intentions, future operations, financial condition and prospects, and business strategies. The words “may,” “will,” “continue,” “estimate,” “project,” “intend,” “believe,” “expect,” “anticipate,” and other similar expressions generally identify forward-looking statements. Forward-looking statements in this Item 2 include, but are not limited to, statements regarding the following: our belief that the recovery from the worldwide economic downturn has continued, our expectation regarding expansion of our international operations, our expectations regarding our new products, the sufficiency of our current cash, cash equivalents, and short-term investment balances, and any cash generated from operations to meet our ongoing operating and capital requirements for the foreseeable future, the use of debt to fund acquisitions, our expectations of earnout arrangements related to acquisitions, and our intent to acquire additional technologies, products, or businesses.

-20-

Forward-looking statements are not guarantees of future performance and are subject to substantial risks and uncertainties that could cause the actual results predicted in the forward-looking statements as well as our future financial condition and results of operations to differ materially from our historical results or currently anticipated results. Investors should carefully review the information contained under the caption “Risk Factors” contained in Part II, Item 1A of this report for a description of risks and uncertainties. All forward-looking statements are based on information available to us on the date hereof, and we assume no obligation to update forward-looking statements.

ITEM 3.    Quantitative and Qualitative Disclosures about Market Risk

During the three months ended March 31, 2015, there were no significant changes to our quantitative and qualitative disclosures about market risk. Please refer to Part II, Item 7A. Quantitative and Qualitative Disclosures About Market Risk included in our Annual Report on Form 10-K for the year ended December 31, 2014 for a more complete discussion on the market risks we encounter.

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.

At December 31, 2014, our management, with the participation of our Chief Executive Officer and Chief Financial Officer, evaluated the effectiveness of our disclosure controls and procedures. Based on that evaluation, our management, including our Chief Executive Officer and Chief Financial Officer, concluded that our disclosure controls and procedures were not effective as of December 31, 2014. This conclusion was based on the material weakness in our internal control over financial reporting further described below.

A material weakness is a deficiency, or combination of deficiencies, in internal control over financial reporting such that there is a reasonable possibility that a material misstatement of the company’s annual or interim consolidated financial statements will not be prevented or detected on a timely basis.

Our management concluded that as of December 31, 2014 our internal control over financial reporting was not effective due to a lack of sufficient resources to effectively design, implement, and operate controls over certain accounts with an appropriate degree of precision. Specifically, the design of controls over the accounting for inventory, accounts receivable and revenue recognition for software contracts and multiple element arrangements was inadequate, which in the aggregate constituted a material weakness in our internal control over financial reporting. This material weakness resulted in misstatements of inventory in our financial statements, which were corrected prior to the issuance of our financial statements as of and for the year ended December 31, 2014.

At March 31, 2015, our management, with the participation of our Chief Executive Officer and Chief Financial Officer, evaluated the effectiveness of our disclosure controls and procedures. Based on that evaluation, our management, including our Chief Executive Officer and Chief Financial Officer, concluded that our disclosure controls and procedures were not effective as of March 31, 2015 due to the material weakness that we identified as of December 31, 2014.

Remediation Efforts to Address Material Weakness

To remediate the material weakness in our internal control over financial reporting described in our Annual Report on Form 10-K for the fiscal year ended December 31, 2014, we made substantive changes to enhance the sufficiency of our resources in 2014. Specifically, we added additional resources with expertise in inventory cost

-21-

accounting and have redesigned our controls to ensure the proper capitalization of overhead costs and the proper monitoring of inventory valuation. We have also added additional resources within our credit and collections group during 2014 and 2015. We expect to add incremental resources in 2015 to enhance the design and operating effectiveness of our controls over accounts receivable.

In addition to the changes described above, we will continue to evaluate and enhance the complement of our resources during 2015, as needed, to address the material weakness identified above. We also expect to finalize our world-wide implementation of a single ERP system during 2015, a project we began in 2011 to consolidate eight different systems into one global platform. The completion of this project will eliminate duplicative processes and increase the capacity of our existing accounting and financial reporting resources to further focus on remediating the material weakness identified above. The material weakness will not be considered remediated until the applicable remedial controls operate for a sufficient period of time and management has concluded, through testing, that the controls are operating effectively.

With the oversight of senior management and our audit committee, we have begun taking the above steps. While our remediation efforts are in process, they have not been completed.

Changes in Internal Control over Financial Reporting

Other than the actions taken as described above under “Remediation Efforts to Address Material Weakness,” there were no changes in our internal control over financial reporting identified in connection with the evaluation required by paragraph (d) of Exchange Act Rules 13a-15 or 15d-15 that occurred during our last fiscal quarter that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Inherent Limitations over Internal Controls

Our management, including our Chief Executive Officer and Chief Financial Officer, does not expect that our disclosure controls and procedures or our internal controls will prevent all errors and all fraud. A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Further, the design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, within Natus have been detected.

PART II.    OTHER INFORMATION

ITEM 1.    Legal Proceedings

We may from time to time become a party to various 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

A description of the risks associated with our business, financial condition and results of operations is set forth in Part 1, Item 1A “Risk Factors” of our Annual Report on Form 10-K for the fiscal year ended December 31, 2014.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Basis of Presentation

Basis of Presentation

The accompanying interim condensed consolidated financial statements of Natus Medical Incorporated (“Natus,” “we,” “us,” “our,” or the “Company”) have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”). 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 the Company’s Annual Report on Form 10-K for the year ended December 31, 2014.

Interim financial reports are prepared in accordance with the rules and regulations of the Securities and Exchange Commission; accordingly, they do not include all of the information and notes required by GAAP for annual financial statements. The interim financial information is unaudited, and except for the prior period correction of errors disclosed below, 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. The consolidated balance sheet as of December 31, 2014 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 the Company’s Annual Report on Form 10-K for the year ended December 31, 2014. We have made certain reclassifications to the prior period to conform to current period presentation.

Operating results for the three months ended March 31, 2015 are not necessarily indicative of the results that may be expected for the year ending December 31, 2015. The accompanying condensed consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation.

Recent Accounting Pronouncements

In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2014-09, Revenue from Contracts with Customers (Topic 606). ASU 2014-09 requires revenue recognition to depict the transfer of goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. ASU 2014-09 sets forth a new revenue recognition model that requires identifying the contract, identifying the performance obligations, determining the transaction price, allocating the transaction price to performance obligations and recognizing the revenue upon satisfaction of performance obligations. The Company is currently evaluating the impact of ASU 2014-09, which is effective for the Company in our fiscal year ending December 31, 2017.

Global Neuro-Diagnostics

The Company acquired Global Neuro-Diagnostics ("GND") through an equity purchase on January 23, 2015. GND's service offers patients a more convenient way to complete routine EEG and video EEG testing which can be performed at the home, hospital or physician's office. The service also provides comprehensive reporting and support to the physician. The cash consideration for GND was $11.4 million. The purchase agreement also included an earn-out condition which the Company estimates to be $3.3 million. This earn-out is contingent upon GND achieving certain revenue milestones from 2015 to 2017.

Valuing intangible assets required us to make significant estimates that will be adjusted in the future; consequently, the purchase price allocation is considered preliminary. Final determination of the value of intangible assets is expected during the second quarter of 2015 and will result in an adjustment to the preliminary purchase price allocation, with an offsetting adjustment to goodwill. Pro forma financial information for the GND acquisition is not presented as it is not considered material.

NicView

On January 2, 2015, the Company purchased the assets of NicView for cash consideration of $1.1 million. NicView provides streaming video for families with babies in the neonatal intensive care unit.

Hearing Screening as a Service

In the first quarter of 2014, the Company entered into two asset purchase agreements for companies in the newborn hearing screening services market for cash consideration of $2.6 million. The purchase agreements also included an earn-out condition which is contingent upon annual revenue growth through 2016. This earn-out condition is currently estimated at $0.8 million. Both acquisitions support the Company’s objective to enter this market that complements our newborn hearing screening device business. This hearing screening services business operates under the name Peloton.

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 Company does not have any financial assets or liabilities measured at fair value on a recurring basis.

The following financial instruments are not measured at fair value on the Company’s consolidated balance sheet as of March 31, 2015 and December 31, 2014, but require disclosure of their fair values: cash and cash equivalents, accounts receivable, accounts payable, and accrued liabilities.

In the third quarter of 2014 the Company listed its facility in Mundelein, Illinois for sale. This asset was measured at fair value less cost to sell as of September 30, 2014 based on market price and is classified as a Level 2 asset. The book value of this asset on June 30, 2014 was $3.6 million. We expensed $2.2 million during the third quarter 2014 for this impairment. As of March 31, 2015 we are carrying the asset as held for sale in other current assets on the balance sheet at a value of $1.4 million.

The Company also has contingent consideration associated with earn-outs from acquisitions. Contingent consideration liabilities are classified as Level 3 liabilities, as the Company uses unobservable inputs to value them, which is a probability-based income approach. Subsequent changes in the fair value of contingent consideration liabilities are recorded within the Company's income statement as an operating expense.

	December 31, 2014		Additions		Payments		March 31, 2015
Liabilities:
Contingent consideration	$	812	$	3,319	$	—	$	4,131
Total	$	812	$	3,319	$	—	$	4,131

As presented in the table above, the significant unobservable inputs used in the fair value measurement of contingent consideration related to the acquisitions are annualized revenue forecasts developed by the Company’s management and the probability of achievement of those revenue forecasts. Significant increases (decreases) in these unobservable inputs in isolation would result in a significantly lower (higher) fair value measurement.

Reserve for Product Warranties

Reserve for Product Warranties

We provide a warranty on all medical device products that is generally one year in length. We also sell extended service agreements on our medical device products that are generally over one year in length. Service for domestic customers is provided by Company-owned service centers that perform all service, repair, and calibration services. Service for international customers is provided by a combination of Company-owned facilities and vendors on a contract basis.

We have accrued a warranty reserve, included in accrued liabilities on the accompanying condensed consolidated balance sheets, for the expected future costs of servicing products during the initial warranty period. We base the liability on actual warranty costs incurred to service those products. Additions to the reserve are based on a combination of factors including the percentage of service department labor applied to warranty repairs, as well as actual service department costs, and other judgments, such as the degree to which the product incorporates new technology. The reserve is reduced as costs are incurred to honor existing warranty obligations.

Income Taxes

Provision for Income Tax Expense

Our effective tax rate (ETR) (provision for income taxes divided by pretax income) for the three months ended March 31, 2015 and 2014 was 31.3% and 30.4%, respectively. Our year-to-date results reflect the projected fiscal year ETR, as adjusted for the impact of any discrete items. Our ETR for the three months ended March 31, 2015 includes the discrete tax impact of the forgiveness of an intercompany loan between the U.S. parent company and its Argentinian subsidiary which increased our ETR by 3.7%. The discrete item recognized during the three months ended March 31, 2014 was not material to the ETR. The decrease in our ETR excluding the impact of discrete items, is due to forecasted shifts in the geographical mix of income. Our ETR for the three months ended March 31, 2015 and 2014 differed from statutory tax rates primarily because of profits taxed in foreign jurisdictions with lower tax rates than the statutory rate.

We recorded a net tax expense of $143,000 of unrecognized tax benefits for the three months ended March 31, 2015. Within the next twelve months, it is possible our uncertain tax benefit may change within a range of approximately zero to $800,000.Our tax returns remain open to examination as follows: U.S. Federal, 2011 through 2013, U.S. States 2010 through 2013 and significant foreign jurisdictions, 2010 through 2013.

Recent Accounting Pronouncements

In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2014-09, Revenue from Contracts with Customers (Topic 606). ASU 2014-09 requires revenue recognition to depict the transfer of goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. ASU 2014-09 sets forth a new revenue recognition model that requires identifying the contract, identifying the performance obligations, determining the transaction price, allocating the transaction price to performance obligations and recognizing the revenue upon satisfaction of performance obligations. The Company is currently evaluating the impact of ASU 2014-09, which is effective for the Company in our fiscal year ending December 31, 2017.

Immaterial Corrections to Prior Period Financial Statements

Immaterial Corrections to Prior Period Financial Statements

Certain amounts previously reported in the consolidated statements of income and statements of cash flows for the three months ended March 31, 2014 have been restated to reflect the correction of an immaterial error as disclosed in the Company’s Annual Report on Form 10-K for the year ended December 31, 2014. The error related to the amount of manufacturing labor and overhead applied to inventory. We believe the effects of the error are not material to our consolidated financial statements.

A summary of the effects of the correction of this error on our consolidated financial statements for the three months ended March 31, 2014 is presented in the table below (in thousands, except per share data):
