NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

(All tabular amounts in millions, except number of shares, which are reflected in thousands, and per share data)

(1) Basis of Presentation

The unaudited consolidated financial statements of Hologic, Inc. (“Hologic” or the “Company”) presented herein have been prepared pursuant to the rules of the Securities and Exchange Commission (the “SEC”) for quarterly reports on Form 10-Q and do not include all of the information and disclosures required by U.S. generally accepted accounting principles (“GAAP”) for annual financial statements. These unaudited financial statements should be read in conjunction with the consolidated financial statements and related notes for the fiscal year ended September 30, 2023 included in the Company’s annual report on Form 10-K filed with the SEC on November 21, 2023. In the opinion of management, the unaudited financial statements and notes contain all adjustments (consisting of normal recurring accruals and all other necessary adjustments) considered necessary for a fair presentation of the Company’s financial position, results of operations and cash flows for the periods presented.

The unaudited consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All intercompany transactions and balances have been eliminated in consolidation.

The preparation of financial statements in conformity with GAAP requires management to make significant estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting periods. Actual results could differ from management’s estimates if past experience or other assumptions do not turn out to be substantially accurate. Operating results for the three and six months ended March 30, 2024 are not necessarily indicative of the results to be expected for any other interim period or the entire fiscal year ending September 28, 2024. Fiscal 2023 was a 53-week fiscal year, and the additional week was included in the first quarter of fiscal 2023 consistent with the Company’s historical fiscal calendar.

Subsequent Events Consideration

The Company considers events or transactions that occur after the balance sheet date but prior to the issuance of the financial statements to provide additional evidence for certain estimates or to identify matters that may require additional disclosure. Subsequent events have been evaluated as required. There were no material recognized or unrecognized subsequent events, except as described below, affecting the unaudited consolidated financial statements as of and for the three and six months ended March 30, 2024.

On April 26, 2024, the Company executed an agreement to acquire Endomagnetics Ltd (“Endomag”) for a purchase price of approximately $310.0 million, subject to working capital and other customary adjustments. The closing is subject to certain regulatory approvals. Endomag, located in the UK, develops and sells breast surgery localization and lymphatic tracing technologies.

(2) Revenue

The Company accounts for revenue pursuant to ASC 606, Revenue from Contracts with Customer (ASC 606) and generates revenue from the sale of its products, primarily medical imaging systems and related components and software, diagnostic tests and assays and surgical disposable products, and related services, which are primarily support and maintenance services on its medical imaging systems, and to a lesser extent installation, training and repairs. In addition, the Company generates service revenue from performing laboratory testing services through its Biotheranostics CLIA laboratory, which is included in its Molecular Diagnostics business. The Company’s products are sold primarily through a direct sales force, and within international markets, there is more reliance on distributors and resellers. Revenue is recorded net of sales tax. The following tables provide revenue from contracts with customers by business and geographic region on a disaggregated basis:

The Company considers revenue to be earned when all of the following criteria are met: the Company has a contract with a customer that creates enforceable rights and obligations; promised products or services are identified; the transaction price, or the amount the Company expects to receive, including an estimate of uncertain amounts subject to a constraint to ensure revenue is not recognized in an amount that would result in a significant reversal upon resolution of the uncertainty, is determinable; and the Company has transferred control of the promised items to the customer. A performance obligation is a promise in a contract to transfer a distinct good or service to the customer and is the unit of account in the contract. The transaction price for the contract is measured as the amount of consideration the Company expects to receive in exchange for the goods and services expected to be transferred. A contract’s transaction price is allocated to each distinct performance obligation and recognized as revenue when, or as, control of the distinct good or service is transferred. Transfer of control for the Company’s products is generally at shipment or delivery, depending on contractual terms, but occurs when title and risk of loss transfers to the customer which represents the point in time when the customer obtains the use of and substantially all of the remaining benefits of the product. As such, the Company’s performance obligation related to product sales is satisfied at a point in time. Revenue from support and maintenance contracts, extended warranty, and professional services for installation, training and repairs is recognized over time based on the period contracted or as the services are performed as these methods represent a faithful depiction of the transfer of goods and services.

The Company recognizes a receivable when it has an unconditional right to payment, which represents the amount the Company expects to collect in a transaction and is most often equal to the transaction price in the contract. Payment terms are typically 30 days in the U.S. but may be longer in international markets. The Company treats shipping and handling costs performed after a customer obtains control of the good as a fulfillment cost and records these costs within costs of product revenue when the corresponding revenue is recognized.

The Company also places instruments (or equipment) at customer sites but retains title to the instrument. The customer has the right to use the instrument for a period of time, and the Company recovers the cost of providing the instrument through the sales of disposables, namely tests and assays in Diagnostics and handpieces in GYN Surgical. These types of agreements include an embedded lease, which is generally an operating lease, for the right to use an instrument and no instrument revenue is recognized at the time of instrument delivery. The Company recognizes a portion of the revenue allocated to the embedded lease concurrent with the sale of disposables over the term of the agreement.

Revenue from laboratory testing services, which is generated by the Company’s Biotheranostics business, is recognized based upon contracted amounts with payors and historical cash collection experience for the same test or same payor group. Revenue is recognized once the laboratory services have been performed, the results have been delivered to the ordering physician, the payor has been identified, and insurance has been verified. The estimated timeframes for cash collection are three months for Medicare payors, six months for Medicare Advantage payors, and nine months for commercial payors.

Generally, the contracts for capital equipment include multiple performance obligations. For contracts with multiple performance obligations, the Company allocates the transaction price to each performance obligation using its best estimate of

11

the standalone selling price of each distinct good or service in the contract. The Company determines its best estimate of standalone selling price using average selling prices over 3- to 12-month periods of data depending on the products or nature of the services coupled with current market considerations. If the product or service does not have a history of sales or if sales volume is not sufficient, the Company relies on prices set by its pricing committees or applicable marketing department adjusted for expected discounts.

Variable Consideration

The Company exercises judgment in estimating variable consideration, which includes volume discounts, sales rebates, product returns and other adjustments. These amounts are recorded as a reduction to revenue and classified as a current liability. The Company bases its estimates for volume discounts and sales rebates on historical information to the extent it is reasonable to be used as a predictive tool of expected future rebates. To the extent the transaction price includes variable consideration, the Company applies judgment in constraining the estimated variable consideration due to factors that may cause reversal of revenue recognized. The Company evaluates constraints based on its historical and projected experience with similar customer contracts. The Company’s contracts for the sale of capital equipment and related components, and assays and tests typically do not provide the right to return product, however, its contracts for the sale of its GYN Surgical and Interventional Breast Solutions surgical handpieces provide for a right of return for a limited period of time. In general, estimates of variable consideration and constraints are not material to the Company’s financial statements.

Remaining Performance Obligations

As of March 30, 2024, the estimated revenue expected to be recognized in the future related to performance obligations that are unsatisfied was approximately $813.5 million. These remaining performance obligations primarily relate to support and maintenance obligations and extended warranty in the Company’s Breast Health and Skeletal Health reportable segments. The Company expects to recognize approximately 26% of this amount as revenue in fiscal 2024, 37% in fiscal 2025, 21% in fiscal 2026, 10% in fiscal 2027, and 6% thereafter. As permitted, the Company does not include remaining performance obligations related to contracts with original expected durations of one year or less in the amounts above.

Contract Assets and Liabilities

The Company discloses accounts receivable separately in the Consolidated Balance Sheets at their net realizable value. Contract assets primarily relate to the Company’s conditional right to consideration for work completed but not billed at the reporting date. Contract assets at the beginning and end of the period, as well as the changes in the balance, were immaterial.

Contract liabilities primarily relate to payments received from customers in advance of performance under the contract. The Company records a contract liability, or deferred revenue, when it has an obligation to provide service, and to a much lesser extent product, to the customer and payment is received or due in advance of performance. Deferred revenue primarily relates to support and maintenance contracts and extended warranty obligations within the Company’s Breast Health and Skeletal Health reportable segments. Contract liabilities are classified as other current liabilities and other long-term liabilities in the Consolidated Balance Sheets. The Company recognized revenue of $37.1 million and $101.6 million in the three and six months ended March 30, 2024, respectively, that was included in the contract liability balance at September 30, 2023. The Company recognized $34.5 million and $101.3 million in the three and six months ended April 1, 2023, respectively, that was included in the contract liability at September 24, 2022.

Practical Expedients

The Company applies a practical expedient to expense costs to obtain a contract with a customer as incurred when the amortization period would have been one year or less. These costs solely comprise sales commissions and typically the commissions are incurred at the time of shipment of product and upon billings for support and maintenance contracts.

12

(3) Leases

Lessor Activity - Leases where Hologic is the Lessor

Certain assets, primarily diagnostics instruments, are leased to customers under contractual arrangements that typically include an operating lease and performance obligations for disposables, reagents and other consumables. These contractual arrangements are subject to termination provisions which are evaluated in determining the lease term for lease accounting purposes. Contract terms vary by customer and may include options to terminate the contract or options to extend the contract. Where instruments are provided under operating lease arrangements, some portion or the entire lease revenue may be variable and subject to subsequent non-lease component (e.g., reagent) sales. Sales-type leases are immaterial. The allocation of revenue between the lease and non-lease components is based on stand-alone selling prices. Lease revenue represented less than 3% of the Company’s consolidated revenue for all periods presented.

(4) Fair Value Measurements

Assets/Liabilities Measured and Recorded at Fair Value on a Recurring Basis

The Company has investments in money market funds, United States Treasury bills and commercial paper that are classified within Level 1 of the fair value hierarchy because they are valued using quoted market prices. These investments are classified as Cash and cash equivalents on the Consolidated Balance Sheets.

The Company also has investments in derivative instruments comprised of interest rate swaps and forward foreign currency contracts, which are valued using analyses obtained from independent third-party valuation specialists based on market observable inputs, representing Level 2 assets. The fair values of these derivative contracts represent the estimated amounts the Company would receive or pay to terminate the contracts. Refer to Note 11 for further discussion and information on derivative contracts. In addition, the Company has a contingent consideration liability that is recorded at fair value, which is based on Level 3 inputs.

The following table summarizes certain fair value information at March 30, 2024 and September 30, 2023 for investment assets and other liabilities measured at fair value on a recurring basis, as well as the carrying amount and amortized cost of certain investments.

Liabilities Measured and Recorded at Fair Value on a Recurring Basis

Changes in the fair value of recurring fair value measurements using significant unobservable inputs (Level 3), which solely consisted of contingent consideration liabilities, during the three and six month periods ended March 30, 2024 and April 1, 2023 were as follows:

		Three Months Ended				Six Months Ended

Assets Measured and Recorded at Fair Value on a Nonrecurring Basis

The Company remeasures the fair value of certain assets and liabilities upon the occurrence of certain events. Such assets are comprised of equity investments and long-lived assets, including property, plant and equipment, intangible assets and goodwill. During the second quarter of fiscal 2024, the Company recorded intangible asset impairment charges of $25.9 million and $0.9 million, respectively, related to its BioZorb developed technology and trade name intangible assets acquired in the Focal acquisition, which is within the Breast Health reportable segment (see Note 18 for further discussion), reducing the carrying value of the assets to $13.9 million and $0.5 million, respectively. During the first quarter of fiscal 2024, the Company recorded a $12.5 million impairment charge for right of use lease assets related to the planned closure of its Mobidiag facilities in Finland and France (see Note 8 for further discussion), reducing the carrying value to zero. In addition, during the first quarter of fiscal 2024, the Company recorded a $4.3 million impairment charge for an in-process research and development

14

project from the Mobidiag acquisition, reducing the carrying value of this asset to $22.4 million. There were no other remeasurements in the three and six months ended March 30, 2024 and April 1, 2023.

Disclosure of Fair Value of Financial Instruments

The Company’s financial instruments mainly consist of cash and cash equivalents, United States Treasury bills, commercial paper, accounts receivable, equity investments, interest rate swaps, forward foreign currency contracts, insurance contracts, accounts payable and debt obligations. The carrying amounts of the Company’s cash and cash equivalents, accounts receivable and accounts payable approximate their fair value due to the short-term nature of these instruments. The Company’s United States Treasury bills, commercial paper, interest rate swaps and forward foreign currency contracts are recorded at fair value. The carrying amount of the insurance contracts are recorded at the cash surrender value, as required by U.S. GAAP, which approximates fair value. The Company believes the carrying amounts of its equity investments approximate fair value.

The Company’s cash and cash equivalents, including current marketable securities, as of March 30, 2024 are as follows:

	Valuation								Balance Sheet Classification
in millions	Cost		Unrealized Gains		Unrealized Losses		Fair Value		Cash and cash equivalents		Investments
Cash	$	1,371.9	$	—	$	—	$	1,371.9	$	1,371.9	$	—
Money market mutual funds	410.2		—		—		410.2		410.2		—
U.S. Treasury bills	348.0		0.1		—		348.1		348.1		—

Total	$	2,179.9	$	0.1	$	—	$	2,180.0	$	2,180.0	$	—

The Company classifies its debt securities as available-for-sale and records them at fair value, with changes in fair value reported as a component of accumulated other comprehensive income (loss), which was immaterial for the period ended March 30, 2024. The Company periodically assesses these securities for potential impairment losses and credit losses. The amount of credit losses, if any, will be determined by comparing the difference between the present value of future cash flows expected to be collected on these securities and the amortized cost. There were no impairments and credit losses related to available-for-sale securities for the three and six months ended March 30, 2024.

The Company classifies all highly liquid investments with stated maturities of three months or less from the date of purchase as cash equivalents. The Company reviews the fair value hierarchy classification on a quarterly basis. Changes in the ability to observe valuation inputs may result in a reclassification of levels for certain securities within the fair value hierarchy. There were no transfers into or out of Level 3 during the three and six months ended March 30, 2024 and April 1, 2023, respectively. There were no sales of available-for-sale securities during the three and six months ended March 30, 2024.

The March 30, 2024 balance of available-for-sale debt securities by contractual maturity is shown in the following table. The fair value of the available-for-sale securities by maturity as of March 30, 2024 and September 30, 2023 are as follows:

	March 30, 2024		September 30, 2023
in millions	Fair Value		Fair Value
Due in three months or less	$	397.9	$	—
Total available-for-sale securities	$	397.9	$	—

Amounts outstanding under the Company’s 2021 Credit Agreement of $1.2 billion aggregate principal as of March 30, 2024 are subject to variable rates of interest based on current market rates, and as such, the Company believes the carrying amount of these obligations approximates fair value. The Company’s 4.625% Senior Notes due 2028 (the “2028 Senior Notes”) and 3.250% Senior Notes due 2029 (the “2029 Senior Notes”) had fair values of $385.9 million and $852.6 million, respectively, as of March 30, 2024 based on their trading prices, representing a Level 1 measurement.

(5) Business Combinations

Fiscal 2023 Acquisitions

15

JW Medical

On July 3, 2023, the Company completed the acquisition of assets from JW Medical Corporation (“JW Medical”) for a purchase price of $6.7 million. JW Medical was a long-standing distributor of the Company’s Breast Health products in South Korea. The majority of the purchase price was allocated to a customer relationship intangible asset with a useful life of 5 years.

Normedi

On April 3, 2023, the Company completed the acquisition of Normedi Nordic AS (“Normedi”) for a purchase price of $7.7 million. Normedi was a long-standing distributor of the Company’s Surgical products in the Nordics region of Europe. The purchase price included $1.1 million for contingent consideration based on incremental revenue growth over a 2-year measurement period. The Company allocated $3.0 million of the purchase price to a customer relationships intangible asset with a useful life of 5 years, and the excess of the purchase price over the net assets acquired was recorded to goodwill.

Contingent Consideration

The Company’s primary contingent consideration liability was related to its acquisition of Acessa Health, Inc. (“Acessa”), which was acquired in August 2020. Acessa developed the ProVu laparoscopic radiofrequency ablation system. The Company estimated the fair value of this liability to be $81.8 million as of the acquisition date. The contingent payments were based on a multiple of annual incremental revenue growth over a three-year period ending annually in December of each of 2021, 2022, and 2023. There was no maximum earnout. Pursuant to ASC 805, Business Combinations (ASC 805), the Company recorded its estimate of the fair value of the contingent consideration liability utilizing the Monte Carlo simulation based on future revenue projections of Acessa, revenue growth rates of comparable companies, implied volatility and applying a risk adjusted discount rate. Each quarter the Company was required to remeasure the fair value of the liability as assumptions change, and such adjustments were recorded in operating expenses. This fair value measurement was based on significant inputs not observable in the market and thus represented a Level 3 measurement as defined in ASC 820, Fair Value Measurements. This fair value measurement was directly impacted by the Company’s estimate of future incremental revenue growth of the business. Accordingly, if actual revenue growth were higher or lower than the estimates within the fair value measurement, the Company would record additional charges or gains. During the second quarter of fiscal 2023, the Company updated its forecasted revenue and recorded a gain of $12.4 million to record the liability at its fair value. The reduction in fair value was due to a decrease in forecasted revenues over the remaining measurement period at that time. During the three months ended December 30, 2023, the third and final measurement period was completed, and the Company recorded a loss of $1.7 million to increase the contingent consideration liability to fair value based on actual revenue results in the final earn-out period. The Company made a final payment of $2.6 million during the second quarter of fiscal 2024.

(6) Strategic Investment

Maverix Medical

On November 13, 2023, the Company entered into an agreement with KKR Comet, LLC, an affiliate of KKR & Co. Inc. (“KKR Comet”), to form a legal entity to develop and acquire innovative technologies and commercial operations within the lung cancer space. The new entity, named Maverix Medical LLC (“Maverix”), is managed by Ajax Health. As part of this strategic investment, the Company contributed $24.5 million in return for 45% ownership in the Class A Common units of Maverix, and both the Company and KKR Comet have committed to make additional capital contributions in proportion to the ownership percentages upon meeting certain objectives and as approved by the Maverix board. In accordance with ASC 810, Consolidation, and ASC 323, Investments - Equity Method and Joint Ventures, the Company determined that this investment should be accounted for under the equity method, which requires the Company to record its proportional share of the entity’s net income (loss). This investment is recorded within Other assets in the Consolidated Balance Sheets, and the Company’s proportionate share of Maverix’s net loss for the three and six months ended March 30, 2024 was immaterial.

(7) Disposition

Sale of SuperSonic Imagine Ultrasound Imaging Business

On September 29, 2023, the Company executed an agreement to sell its SSI ultrasound imaging business to SSH Holdings Limited for a sales price of $1.9 million in cash. Under the terms of the contract, the Company agreed to fund the SSI business with $33.2 million of cash. The sale was completed on October 3, 2023. The Company also agreed to provide certain transition services for up to one year, depending on the nature of the service. The SSI ultrasound imaging asset group met the criteria to be classified as assets held-for-sale in the fourth quarter of fiscal 2023. As a result, the Company recorded a charge of

16

$51.7 million in the fourth quarter of fiscal 2023 to record the asset group to its fair value less costs to sell pursuant to ASC 360, Property, Plant and Equipment-Impairment or Disposal of Long-Lived Assets.

The assets and liabilities of the disposed business at the date of disposition were as follows:

Assets:
Cash	$	33.2
Accounts receivable	4.5
Inventory	16.2
Prepaid expenses and other assets	8.6
Valuation allowance	(50.6)
Total assets disposed of	$	11.9
Liabilities:
Accounts payable	$	3.1
Accrued expenses	5.1
Total liabilities disposed of	$	8.2

The valuation allowance of $50.6 million was recorded to appropriately reflect the assets held-for-sale classification in the Consolidated Balance Sheet in the fourth quarter of fiscal 2023 relative to the loss recorded and the net tangible assets disposed.

The Company concluded that this disposal did not qualify as a discontinued operation as the sale of the SSI ultrasound imaging business was deemed to not be a strategic shift having or that will have a major effect on the Company’s operations and financial results.

(8) Restructuring

During the first quarter of fiscal 2024, the Company further refined its strategy for the Mobidiag business, which is within the Diagnostics reportable segment. The strategy change included the decision to discontinue the manufacture and sale of certain products, closure of its facilities in Finland and France, and to move the development activities and operations to the Company’s San Diego, California location. As such, the Company determined certain fixed assets lives should be shortened and that lease assets were impaired at the affected facilities and recorded accelerated depreciation of $7.2 million and a lease asset impairment charge of $12.5 million. In connection with this plan, the Company finalized its decision to terminate the employees at these locations, totaling 190. The Company initiated discussions with the respective Works Councils at the end of the first quarter of fiscal 2024. In addition, the Company recorded the minimum statutory severance benefit for the employees located in France of $1.8 million pursuant to ASC 712, Compensation Nonretirement Postemployment Benefits. During the second quarter of fiscal 2024, the Company finalized its negotiations with the respective Works Councils and communicated the termination and related severance benefits to the affected employees. The Company has estimated the total severance charges, including accelerated stock compensation, to be approximately $12.2 million. The majority of the severance benefits will be recorded pursuant to ASC 420, Exit or Disposal Cost Obligations (ASC 420), which requires the severance benefits to be recognized ratably over the service period to obtain such benefits. The employees will cease employment in phases. During the second quarter of fiscal 2024, the Company recorded $4.0 million for severance benefits. This action is expected to be completed by the second quarter of fiscal 2025.

During the first quarter of fiscal 2022, the Company finalized its decision to close its Danbury, Connecticut facility where it manufactures its Breast Health capital equipment products. The manufacturing of the Breast Health capital equipment products and all other support services are in the process of being transferred to the Company’s Newark, Delaware facility. The transition is expected to be completed by the third quarter of fiscal 2025. In addition, research and development, sales and services support and administrative functions have been transferred to the Newark, Delaware and Marlborough, Massachusetts facilities. The employees were notified of the closure during the first quarter of fiscal 2022, and the majority of employees located in Danbury were given the option to relocate to the new locations. The Company is recording severance benefits ratably over the required service period pursuant to ASC 420. As a result, the Company recorded severance and benefits charges of $1.3 million and $1.8 million during the three and six months ended March 30, 2024, respectively, and $0.3 million and

17

$1.0 million during the three and six months ended April 1, 2023, respectively. The Company estimates that total severance charges, including retention, will be approximately $7.5 million.

(9) Borrowings and Credit Arrangements

The Company’s borrowings consisted of the following: 

	March 30, 2024		September 30, 2023
Current debt obligations, net of debt discount and deferred issuance costs:
Term Loan	$	37.4	$	287.0
Total current debt obligations	$	37.4	$	287.0
Long-term debt obligations, net of debt discount and issuance costs:
Term Loan	$	1,177.1	$	1,195.6
2028 Senior Notes	397.2		396.8

Total long-term debt obligations	$	2,514.1	$	2,531.2
Total debt obligations	$	2,551.5	$	2,818.2

2021 Credit Agreement

On September 27, 2021, the Company refinanced its then existing term loan and revolving credit facility with Bank of America, N.A. in its capacity as Administrative Agent, Swing Line Lender and L/C Issuer, and certain other lenders (the “2018 Credit Agreement”) by entering into a Refinancing Amendment (the “2021 Credit Agreement”). On August 22, 2022, the Company further amended the 2021 Credit Agreement to address the planned phase out of LIBOR by the UK Financial Conduct Authority. Under this amendment, the interest rates applicable to the loans under the 2021 Credit Agreement denominated in U.S. dollars were converted to a variant of the secured overnight financing rate (“SOFR”), as established from time to time by the Federal Reserve Bank of New York, plus a corresponding spread.

The 2021 Credit Agreement provided a $1.5 billion secured term loan facility (the “2021 Term Loan”) and a $2.0 billion revolving credit facility (the “2021 Revolver”). As of March 30, 2024, the principal amount outstanding under the 2021 Term Loan was $1.2 billion, and the interest rate was 6.43% per annum. No amounts were outstanding under the 2021 Revolver, and the full amount was available to be borrowed by the Company. During the first quarter of fiscal 2024, the Company made a $250.0 million voluntary prepayment on the 2021 Term Loan.

Interest expense, weighted average interest rates, and the interest rate at the end of period under the 2021 Credit Agreement were as follows: 

	Three Months Ended						Six Months Ended
	March 30, 2024			April 1, 2023			March 30, 2024			April 1, 2023
Interest expense	$	21.2		$	22.5		$	43.8		$	42.9
Weighted average interest rate	6.43		%	5.74		%	6.43		%	5.39		%
Interest rate at end of period	6.43		%	5.91		%	6.43		%	5.91		%

The Company’s effective interest rate swap agreements, the first of which fixed the SOFR component of the variable interest rate on $1.0 billion of aggregate principal under the 2021 Term Loan at 1.23% and terminated on December 17, 2023, and the second of which fixes the SOFR component of the variable interest rate on $500 million of aggregate principal under the 2021 Term Loan at 3.46% commencing on December 17, 2023 and terminating on December 27, 2024, resulted in the Company receiving $2.4 million and $12.0 million during the three and six months ended March 30, 2024, respectively, and $8.6 million and $15.2 million during the three and six months ended April 1, 2023, respectively. These amounts were recorded as a reduction to interest expense.

The 2021 Credit Agreement contains two financial covenants; a total leverage ratio and an interest coverage ratio, both of which are measured as of the last day of each fiscal quarter. These terms, and calculations thereof, are defined in further detail in the 2021 Credit Agreement. As of March 30, 2024, the Company was in compliance with these covenants.

18

2028 Senior Notes

As of March 30, 2024, the Company had 4.625% Senior Notes due 2028 (the “2028 Senior Notes”) outstanding in the aggregate principal balance of $400 million.

(10) Trade Receivables and Allowance for Credit Losses

The Company applies ASU No. 2016-13, Financial Instruments - Credit Losses (Topic 326) to its trade receivables and allowances for credit losses, which requires that financial assets measured at amortized cost be presented at the net amount expected to be collected. The expected credit losses are developed using an estimated loss rate method that considers historical collection experience, current conditions, and reasonable and supportable forecasts that affect the collectability of the reported amount. The estimated loss rates are applied to trade receivables with similar risk characteristics such as the length of time the balance has been outstanding and the location of the customer. In certain instances, the Company may identify individual trade receivable assets that do not share risk characteristics with other trade receivables, in which case the Company records its expected credit losses on an individual asset basis. For example, potential adverse changes to customer liquidity, such as the ongoing and possible future effects of global challenges including macroeconomic uncertainties, such as inflation, rising interest rates and availability of capital markets, and other economic disruptions. To date, the Company has not experienced significant customer payment defaults, or identified other significant collectability concerns. In connection with assessing credit losses for individual trade receivable assets, the Company considers significant factors relevant to collectability including those specific to the customer such as bankruptcy, length of time an account is outstanding, and the liquidity and financial position of the customer. If a trade receivable asset is evaluated on an individual basis, the Company excludes those assets from the portfolios of trade receivables evaluated on a collective basis.

The following is a rollforward of the allowance for credit losses as of March 30, 2024 compared to April 1, 2023:

	Balance at Beginning of Period		Credit Loss		Write-offs, Payments and Foreign Exchange		Balance at End of Period
Six Months Ended
March 30, 2024	$	38.5	$	5.5	$	(1.3)	$	42.7
April 1, 2023	$	37.7	$	1.9	$	(0.2)	$	39.4

(11) Derivatives

Interest Rate Swaps - Cash Flow Hedge

The Company is exposed to certain risks arising from both its business operations and economic conditions. The Company manages its exposure to some of its interest rate risk through the use of interest rate swaps, which are derivative financial instruments. The Company does not use derivatives for speculative purposes. For a derivative that is designated as a

19

cash flow hedge, changes in the fair value of the derivative are recognized in accumulated other comprehensive income (“AOCI”) to the extent the derivative is effective at offsetting the changes in the cash flows being hedged until the hedged item affects earnings.

In fiscal 2019, the Company entered into an interest rate swap contract with an effective date of December 23, 2020 and a termination date of December 17, 2023 to hedge a portion of its variable rate debt. On August 25, 2022, the interest rate swap agreement was restructured (consistent with the 2021 Credit Agreement) to convert the benchmark interest rate from LIBOR to the SOFR rate effective September 23, 2022 with a termination date of December 17, 2023. The Company applied the practical and optional expedients in ASC 848, Reference Rate Reform, in evaluating the impact of modifying the contract, which resulted in no change to the accounting for this derivative contract. The notional amount of this swap was $1.0 billion. The restructured interest rate swap fixed the SOFR component of the variable interest rate on $1.0 billion of the notional amount under the 2021 Credit Agreement at 1.23%. The critical terms of the restructured interest rate swap were designed to mirror the terms of the Company’s SOFR-based borrowings under the 2021 Credit Agreement and therefore were highly effective at offsetting the cash flows being hedged. The Company designated this derivative as a cash flow hedge of the variability of the SOFR-based interest payments on $1.0 billion of principal. Therefore, changes in the fair value of the swap were recorded in AOCI. The contract ended during the first quarter of fiscal 2024 and as a result the fair value of this derivative was $0.0 million as of March 30, 2024.

On March 23, 2023, the Company entered into two consecutive interest rate swap contracts with the first contract having an effective date of December 17, 2023 and terminating on December 27, 2024, and the second contract having an effective date of December 27, 2024 and terminating on September 25, 2026. The notional amount of these swaps is $500 million, and the first interest rate swap fixes the SOFR component of the variable interest rate at 3.46%, and the second interest rate swap fixes the SOFR component of the variable interest rate at 2.98%. The critical terms of the interest rate swaps are designed to mirror the terms of the Company’s SOFR-based borrowings under the 2021 Credit Agreement and therefore are highly effective at offsetting the cash flows being hedged. The Company designated this derivative as a cash flow hedge of the variability of the SOFR-based interest payments on $500 million of principal. Therefore, changes in the fair value of the swap are recorded in AOCI. The fair value of these swaps was an asset position of $14.2 million as of March 30, 2024.

Forward Foreign Currency Exchange Contracts and Foreign Currency Option Contracts

The Company enters into forward foreign currency exchange contracts and foreign currency option contracts to mitigate certain operational exposures from the impact of changes in foreign currency exchange rates. Such exposures result from the portion of the Company’s cash and operations that are denominated in currencies other than the U.S. dollar, primarily the Euro, the UK Pound, the Australian dollar, the Canadian dollar, the Chinese Yuan and the Japanese Yen. These foreign currency contracts are entered into to support transactions made in the ordinary course of business and are not speculative in nature. The contracts are generally for periods of one year or less. The Company did not elect hedge accounting for these contracts; however, the Company may seek to apply hedge accounting in future scenarios. As of March 30, 2024 the notional amount was $190.3 million. The change in the fair value of these contracts is recognized directly in earnings as a component of other income (expense), net.

Realized and unrealized gains and losses from these contracts, which were the only derivative contracts not designated for hedge accounting, for the three and six months ended March 30, 2024 and April 1, 2023, respectively, were as follows:

Litigation and Related Matters

21

On November 4, 2022, a product liability complaint was filed against the Company in Massachusetts state court by a group of plaintiffs who claim they sustained injuries caused by the BioZorb 3D Bioabsorbable Marker, and additional complaints were subsequently filed alleging similar claims. The BioZorb device is an implantable three-dimensional marker that helps clinicians overcome certain challenges presented by breast conserving cancer surgery (lumpectomy). The complaints allege that the plaintiffs suffered side effects that were not disclosed in the BioZorb instructions for use and make various additional claims related to the design, manufacture and marketing of the device. Complaints have been filed on behalf of 88 plaintiffs, one pending in Massachusetts state court, and the remainder in United States District Court for the District of Massachusetts. Discovery is ongoing. While the Company believes it has valid defenses and plans to vigorously defend its position, litigation can be costly and unpredictable, and at this early stage the Company cannot reasonably assess the outcome of this matter.

The Company is a party to various other legal proceedings, claims, governmental and/or regulatory inspections, inquiries and investigations arising out of the ordinary course of its business. The Company believes that except for those matters described above there are no other proceedings, claims, inspections, inquiries or investigations pending against it, the ultimate resolution of which are reasonably likely based upon management’s assessment, to have a material adverse effect on its financial condition or results of operations. It is possible that future results for any particular quarter or annual period may be materially affected by changes in our assumptions or the effectiveness of our strategies relating to these matters. In all cases, at each reporting period, the Company evaluates whether or not a potential loss amount or a potential range of loss is probable and reasonably estimable under ASC 450, Contingencies (ASC 450). Legal costs are expensed as incurred.

Dividend yield	—			—			—			—
Weighted average fair value of options granted	$	26.27		$	27.42		$	25.04		$	25.92

The Company granted 0.7 million and 0.6 million restricted stock units (“RSUs”) during the six months ended March 30, 2024 and April 1, 2023, respectively, with weighted-average grant date fair values of $72.00 and $74.44 per unit, respectively. In addition, the Company granted 0.1 million and 0.1 million performance stock units (“PSUs”) during the six months ended March 30, 2024 and April 1, 2023, respectively, to members of its senior management team, which have a weighted-average grant date fair value of $71.92 and $74.35 per unit, respectively. Each recipient of PSUs is eligible to receive between zero and 200% of the target number of shares of the Company’s common stock at the end of a three-year performance period, provided that the Company’s defined Return on Invested Capital metrics are achieved. The Company also granted 0.1 million and 0.1 million of FCF PSUs based on a three-year cumulative free cash flow measure (“FCF PSUs”) to members of its senior management team, which had a grant date fair value of $71.92 and $74.35 per unit during the six months ended March 30, 2024 and April 1, 2023, respectively. Each recipient of FCF PSUs is eligible to receive between zero and 200% of the target number of shares of the Company’s common stock at the end of the three-year measurement period. The PSUs and FCF PSUs cliff-vest three years from the date of grant, and the Company recognizes compensation expense ratably over the required service period based on its estimate of the probable number of shares that will vest upon achieving the measurement criteria. If there is a change in the estimate of the number of shares that are probable of vesting, the Company will cumulatively adjust compensation expense in the period that the change in estimate is made. The Company also granted 0.1 million and 0.1 million market-based awards (“MSUs”) to members of its senior management team during the six months ended March 30, 2024 and April 1, 2023, respectively. Each recipient of MSUs is eligible to receive between zero and 200% of the target number of shares of the Company’s common stock at the end of a three-year performance period based upon achieving a certain total shareholder return relative to a defined peer group. The MSUs were valued at $88.06 and $97.91 per share using the Monte Carlo simulation model in fiscal 2024 and 2023, respectively. The MSUs cliff-vest three years from the date of grant, and the Company recognizes compensation expense for the MSUs ratably over the service period. At March 30, 2024, there was 1.7 million in aggregate unvested RSUs, PSUs, FCF PSUs and MSUs outstanding.

At March 30, 2024, there was $14.4 million and $67.2 million of unrecognized compensation expense related to stock options and stock units (comprised of RSUs, PSUs, FCF PSUs and MSUs), respectively, to be recognized over a weighted-average period of 2.4 and 2.0 years, respectively.

(16) Business Segments and Geographic Information

The Company has four reportable segments: Diagnostics, Breast Health, GYN Surgical and Skeletal Health. The Company measures and evaluates its reportable segments based on segment revenues and operating income adjusted to exclude the effect of non-cash charges (such as intangible asset amortization expense, and goodwill and intangible asset impairment charges), transaction and integration expenses for acquisitions, restructuring, consolidation and divestiture charges, litigation charges, and other one-time or unusual items.

24

Identifiable assets for the reportable segments consist of inventories, intangible assets, goodwill, and property, plant and equipment. The Company fully allocates depreciation expense to its reportable segments. The Company has presented all other identifiable assets as corporate assets. There were no inter-segment revenues during the three and six months ended March 30, 2024 and April 1, 2023. Segment information is as follows:

(17) Income Taxes

In accordance with ASC 740, Income Taxes, each interim period is considered integral to the annual period, and tax expense is measured using an estimated annual effective tax rate. An entity is required to record income tax expense each quarter based on its annual effective tax rate estimated for the full fiscal year and use that rate to provide for income taxes on a current year-to-date basis, adjusted for discrete taxable events that occur during the interim period.

For the three months ended March 30, 2024, the Company recorded income tax expense of $41.6 million resulting in an effective tax rate of 19.7%. For the six months ended March 30, 2024, the Company recorded an income tax benefit of $13.6 million, resulting in an effective tax rate of (3.4)%.

The effective tax rate for the three months ended March 30, 2024 was lower than the U.S. statutory tax rate primarily due to the U.S. deduction for foreign derived intangible income and the geographic mix of income earned by the Company’s international subsidiaries, which are generally taxed at rates lower than the U.S. statutory tax rate. The effective tax rate for the six months ended March 30, 2024 was lower than the U.S. statutory tax rate primarily due to a discrete tax benefit of $107.2 million related to a worthless stock deduction on the investment in one of the Company’s international subsidiaries recorded in the first quarter of fiscal 2024, the U.S. deduction for foreign derived intangible income, and the geographic mix of income earned by the Company’s international subsidiaries, which are generally taxed at rates lower than the U.S. statutory tax rate.

The Company recorded income tax expense of $60.8 million and $112.5 million for the three and six months ended April 1, 2023, resulting in effective tax rates of 21.8% and 21.7%, respectively.

The effective tax rates for the three and six months ended April 1, 2023 were higher than the U.S. statutory tax rate primarily due to increases to income tax reserves, the global intangible low-taxed income inclusion, and state income taxes, partially offset by the impact of the U.S. deduction for foreign derived intangible income, the geographic mix of income earned by the Company’s international subsidiaries, which are generally taxed at rates lower than the U.S. statutory tax rate, and federal and state tax credits.

Non-Income Tax Matters

The Company is subject to tax examinations for value added, sales-based, payroll and other non-income tax items. A number of these examinations are ongoing in various jurisdictions. The Company takes certain non-income tax positions in the jurisdictions in which it operates and records loss contingencies pursuant to ASC 450. Such amounts were not material for any of the periods presented. In the normal course of business, the Company's positions and conclusions related to its non-income tax positions could be challenged, resulting in assessments by governmental authorities. While the Company believes estimated losses previously recorded are reasonable, certain audits are still ongoing and additional charges could be recorded in the future.

The estimated remaining amortization expense of the Company’s acquired intangible assets as of March 30, 2024 for each of the five succeeding fiscal years was as follows:

Remainder of Fiscal 2024	$	97.8
Fiscal 2025	$	183.2
Fiscal 2026	$	153.3
Fiscal 2027	$	66.3
Fiscal 2028	$	63.2

During the second quarter of fiscal 2024, in connection with commencing its company-wide annual strategic planning process, the Company identified indicators of impairment in its BioZorb product line, which was part of the Focal acquisition. As a result, the Company performed an undiscounted cash flow analysis pursuant to ASC 360, Property, Plant and Equipment - Overall, to determine if the cash flows expected to be generated by the BioZorb product line over the remaining estimated useful life of the primary asset were sufficient to recover the carrying value of the asset group. Based on this analysis the undiscounted cash flows were not sufficient to recover the carrying value of the long-lived assets. Therefore, the Company was required to perform Step 3 of the impairment test and determine the fair value of the asset group. To estimate the fair value of the asset group, the Company utilized the income approach, which is based on a discounted cash flow (DCF) analysis and calculated the fair value by estimating the after-tax cash flows attributable to the asset group and then discounting the after-tax cash flows to present value using a risk-adjusted discount rate. Based on this analysis, the fair value of the BioZorb asset group was below its carrying value and the Company recorded an impairment charge of $26.8 million during the second quarter of fiscal 2024. The impairment charge was allocated to the long-lived assets on a pro-rata basis as follows: $25.9 million to developed technology and $0.9 million to trade names, which reduced the carrying value of the assets to $13.9 million and $0.5 million respectively. The Company also re-evaluated the remaining useful lives of the intangible assets and concluded no changes were necessary.

During the first quarter of fiscal 2024, the Company assessed its only in-process research and development intangible asset from its Mobidiag acquisition for impairment. The Company determined the fair value of this indefinite lived asset utilizing the DCF model and recorded a $4.3 million impairment charge, reducing the fair value of this asset to $22.4 million. The reduction in fair value of this asset was primarily due to a reduction in forecasted revenues and a delay in the timing of completing the project. In addition, the Company determined that the useful life of the customer relationship and trade name intangible assets from its Mobidiag acquisition should be shortened and recorded accelerated amortization expense of $7.3 million to bring the net carrying values to zero.

OVERVIEW

We are a developer, manufacturer and supplier of premium diagnostics products, medical imaging systems and surgical products focused on women’s health and well-being through early detection and treatment. We sell and service our products through a combination of direct sales and service personnel and a network of independent distributors and sales representatives. We operate in four segments: Diagnostics, Breast Health, GYN Surgical and Skeletal Health.

Through our Diagnostics segment, we offer a wide range of diagnostic products, which are used primarily to aid in the screening and diagnosis of human diseases. Our primary Diagnostics products include our molecular diagnostic assays, which run on our advanced instrumentation systems (Panther, Panther Fusion and Tigris), our ThinPrep cytology system, and the Rapid Fetal Fibronectin Test. Our Aptima family of molecular diagnostic assays is used to detect, among other things, the infectious microorganisms that cause common sexually transmitted diseases, or STDs, such as chlamydia and gonorrhea, or CT/NG; certain high-risk strains of human papillomavirus, or HPV; Trichomonas vaginalis, the parasite that causes trichomoniasis; Mycoplasma genitalium; and Herpes Simplex viruses 1 and 2. We also offer viral load tests for the quantitation of Hepatitis B virus, Hepatitis C virus, human immunodeficiency virus, or HIV-1, and human cytomegalo virus, or CMV, for use on our Panther instrument system. In addition, we offer bacterial vaginosis and candida vaginitis assays for the diagnosis of vaginitis, a common and complex ailment affecting millions of women a year. Our assay portfolio also includes diagnostic tests for a range of acute respiratory infections, including SARS-CoV-2, various strains of influenza and parainfluenza, and respiratory syncytial virus, as well as a test for the detection of Group B Streptococcus, or GBS, that are run on the Panther Fusion system, a field upgradeable instrument addition to the base Panther system. In response to the COVID-19 pandemic, we developed and launched the Aptima SARS-CoV-2 assay and the Aptima SARS-CoV-2/Flu assay (each of which runs on our standard Panther system) and the Panther Fusion SARS-CoV-2 assay (which runs on our Panther Fusion system). In May 2022, we CE-marked two new molecular assays, Panther Fusion EBV Quant assay for quantitation of Epstein-Barr virus, and the Panther Fusion BKV Quant assay for quantitation of the BK virus. These two new assays are the first quantitative real-time PCR assays on the Panther Fusion system. These assays, along with the Aptima CMV Quant assay already available in Europe, expand our menu of transplant monitoring assays. The ThinPrep System is primarily used in cytology applications, such as cervical cancer screening, and the Rapid Fetal Fibronectin Test assists physicians in assessing the risk of pre-term birth. We also generate service revenues from our CLIA-certified laboratory for testing related to breast cancer and all metastatic cancers.

Our Breast Health segment offers a broad portfolio of solutions for breast cancer care primarily in the areas of radiology, breast surgery, pathology and treatment. These solutions include 3D digital mammography systems, image analytics software utilizing artificial intelligence, reading workstations, minimally invasive breast biopsy guidance systems, breast biopsy site

31

markers, localization, specimen radiology, connectivity solutions and breast conserving surgery products. Our most advanced breast imaging platforms, the 3Dimensions and Selenia 3D Dimensions systems, utilize tomosynthesis to produce 3D images that show multiple contiguous slice images of the breast, which we refer to as the Genius 3D Mammography exam.

Our GYN Surgical products include our MyoSure hysteroscopic tissue removal system, or MyoSure, our NovaSure endometrial ablation system, or NovaSure, our Fluent fluid management system, or Fluent, our Acessa ProVu laparoscopic radiofrequency ablation system, or Acessa ProVu, as well as our CoolSeal vessel sealing portfolio and our JustRight surgical stapler. The MyoSure suite of devices offers four options to provide incision-less removal of fibroids, polyps, and other pathology within the uterus. The NovaSure portfolio is comprised of the NovaSure CLASSIC device, NovaSure ADVANCED device and the NovaSure V5 device for the treatment of abnormal uterine bleeding. The Fluent system is a fluid management system that provides liquid distention during diagnostic and operative hysteroscopic procedures. The Acessa ProVu system is a fully integrated system that uses laparoscopic ultrasound, guidance mapping and radiofrequency ablation to treat nearly all types of fibroids. The CoolSeal portfolio includes the Trinity, Reveal, and Mini advanced bipolar vessel sealing devices. The JustRight 5 mm stapler features a smaller instrument profile and is used for laparoscopic general and pediatric surgery.

Our Skeletal Health segment’s products include the Horizon DXA, a dual energy x-ray system, which evaluates bone density and performs body composition assessments, and the Fluoroscan Insight FD mini C-arm, which assists in performing minimally invasive orthopedic surgical procedures on a patient’s extremities, such as the hand, wrist, knee, foot, and ankle.

We had a decrease in product revenues in both the current three and six month periods compared to the corresponding periods in the prior year primarily due to the decrease in revenues in the Diagnostics business as COVID-19 assay sales declined significantly and to a lesser extent a decrease in Skeletal Health revenue. In addition, the prior year six month period included an extra week based on our fiscal calendar. This decrease was partially offset by an increase in GYN Surgical revenue in both the current three and six month periods and improved performance by our Breast Health division in the current six month period as supply chain constraints continued to have a significant impact on Breast Health product revenues in the first quarter of the prior year.

Diagnostics product revenues decreased $16.0 million and $128.9 million, or 3.7% and 13.3%, respectively, in the current three and six month periods compared to the corresponding periods in the prior year primarily due to a decrease in Molecular Diagnostics revenues of $21.6 million and $129.1 million, respectively, and a decrease in Blood Screening of $3.2 million and $2.0 million, respectively. These decreases were partially offset by an increase in Cytology & Perinatal revenues of $8.8 million and $2.3 million, respectively. The Molecular Diagnostics decrease was primarily attributable to a decrease of $47.9 million and $148.0 million, respectively, in sales from our two SARS-CoV-2 assays (primarily the Aptima SARS-CoV-2 assay and to a lesser extent the Panther Fusion SARS-CoV-2 assay) due to lower volumes, which we primarily attribute to lower demand from an improvement in the COVID-19 pandemic compared to the prior year. We expect sales of our SARS-CoV-2 assays to continue to be significantly lower in fiscal 2024 compared to fiscal 2023. These decreases were partially offset by an increase in sales of our Fusion respiratory products, primarily flu assays, and our BV/CV assays. Within Cytology & Perinatal, in the current three and six month periods, we had an increase in sales of our instruments, primarily the Genius Digital Diagnostics system and ThinPrep processors. In the current three month period, we had an increase in ThinPrep pap tests primarily in international markets.

Breast Health product revenues increased $0.1 million and $50.3 million, or 0.0% and 12.0%, respectively, in the current three and six month periods compared to the corresponding periods in the prior year. The increase in the current three and six month periods compared to the corresponding periods in the prior year is primarily due to an increase in volumes of our digital mammography systems, primarily 3Dimensions systems and related workstation and workflow products, including software, partially offset by a reduction in 2D system sales. The increase in 3Dimensions sales was much more significant in the current six month period compared to the increase in the current three month period. In addition, we had an increase in sales of our interventional breast solutions products primarily driven by Brevera and ATEC needles and an increase in sales of Affirm Prone biopsy systems. The increase in volume of sales of our capital equipment was primarily driven by the supply chain constraints in the first quarter of the prior year related to electronic components. These increases were partially offset by a decrease in sales of SSI ultrasound imaging products of $4.1 million and $7.0 million, respectively, in the current three and six month periods as a result of the sale of this business in the beginning of the first quarter of fiscal 2024.

GYN Surgical product revenues increased $11.9 million and $17.7 million, or 8.3% and 6.0%, respectively, in the current three and six month periods compared to the corresponding periods in the prior year primarily due to increases in the sales volume of our MyoSure devices and Fluent Fluid Management products, which we primarily attribute to the recovery of procedure rates from the impact of the COVID-19 pandemic. These increases were partially offset by a decrease in sales of NovaSure devices, which we primarily attribute to an increase in the use of alternative treatments.

33

Skeletal Health product revenues decreased $5.4 million and $6.9 million, or 23.6% and 16.8%, respectively, in the current three and six month periods compared to the corresponding periods in the prior year primarily due to a decrease in sales volume and average selling prices of our Insight FD systems and our Horizon DXA systems.

Product revenues by geography as a percentage of total product revenues were as follows:

	Three Months Ended				Six Months Ended
	March 30, 2024		April 1, 2023		March 30, 2024		April 1, 2023
United States	72.6	%	73.0	%	72.4	%	74.0	%
Europe	14.5	%	16.0	%	14.9	%	15.4	%
Asia-Pacific	6.6	%	6.6	%	6.6	%	6.4	%
Rest of World	6.3	%	4.4	%	6.1	%	4.2	%
	100.0	%	100.0	%	100.0	%	100.0	%

In the current three and six month periods compared to the corresponding periods in the prior year, the percentage of product revenue derived from the U.S. and Europe decreased which we primarily attribute to the decrease of sales from our two SARS-CoV-2 assays due to lower volumes, as discussed above. This was partially offset by an increase in the U.S. of Breast Health capital equipment sales and related workflow product including software. The percentage of product revenue increased in Rest of World in the current year three and six month periods compared to the corresponding periods in the prior year primarily due to an increase in Breast Health capital equipment sales and Surgical sales for Canada, the Middle East and Latin America.

Service and Other Revenues

	Three Months Ended												Six Months Ended
	March 30, 2024				April 1, 2023				Change				March 30, 2024				April 1, 2023				Change
	Amount		% of Total Revenue		Amount		% of Total Revenue		Amount		%		Amount		% of Total Revenue		Amount		% of Total Revenue		Amount		%

Service and other revenues consist primarily of revenue generated from our field service organization to provide ongoing service, installation and repair of our products. The majority of these revenues are generated within our Breast Health segment. Our Diagnostics segment also generates service revenue from lab testing from our Biotheranostics CLIA laboratory testing business. The slight increase in service and other revenue in the current three month period compared to the corresponding period in the prior year was primarily due to an increase in service contract revenue and higher lab testing volumes from our Biotheranostics business, partially offset by a decrease in spare parts billings. The decrease in service and other revenue in the current six month period compared to the corresponding period in the prior year is primarily due to the prior year period included an extra week of service contract activity, and there was lower spare parts sales in the current year period, partially offset by higher lab testing volumes from our Biotheranostics business.

** Percentage not meaningful

Cost of Product Revenues. The cost of product revenues as a percentage of product revenues was 37.3% and 37.2%, respectively, in the current three and six month periods compared to 34.9% and 34.1% in the corresponding periods in the prior year. Cost of product revenues as a percentage of revenue increased in the current three and six month periods primarily due to a decrease in sales of our SARS-CoV-2 assays, which have higher gross margins compared to our other Diagnostic products, and comprised 2.8% and 3.0% of total product revenue in the three and six months periods, respectively, compared to 8.5% and 11.5%, respectively, in the corresponding period in the prior year.

Diagnostics’ product costs as a percentage of revenue increased in the current three and six month periods compared to the corresponding periods in the prior year primarily due to lower sales of our SARS-CoV-2 assays, unfavorable manufacturing variances and an increase in instrument sales which have lower margins. Partially offsetting these decreases to gross margin was an increase in volumes of our Women’s Health Aptima and Fusion assays and, in the current three month period an increase in ThinPrep pap tests and a decrease in scrap and lower inventory reserves.

Breast Health’s product costs as a percentage of revenue decreased in the current three and six month periods compared to the corresponding periods in the prior year primarily due to higher sales volumes of our higher margin products, primarily 3D Dimensions and related software products, improved manufacturing utilization and a slight increase in average selling prices of our biopsy disposables, as well as an increase in prices across multiple products in Europe. Also contributing to the decrease in product costs as a percentage of revenue in the current three and six month periods was a decrease in inventory reserves and freight costs.

GYN Surgical’s product costs as a percentage of revenue increased in the current three and six month periods compared to the corresponding periods in the prior year primarily due to product mix of higher volumes of lower margin products, mostly attributable to sales of our Fluent Fluid Management systems, lower volumes of our NovaSure devices and unfavorable manufacturing variances partially offset by an increase in volume of higher margin products, primarily MyoSure devices, as procedure rates recovered from the impact of the COVID-19 pandemic.

Skeletal Health’s product costs as a percentage of revenue increased in the current three month period compared to the corresponding period in the prior year primarily due to a decrease in volume of Horizon DXA systems and upgrades which have higher margins and a decrease in average selling prices of Horizon DXA systems and Insight FD systems. Product costs as a percentage of revenue decreased in the current six month period compared to the corresponding period in the prior year primarily due to a decrease in sales of Insight FD products, which have lower gross margins.

Amortization of Intangible Assets. Amortization of intangible assets relates to acquired developed technology, which is generally amortized over its estimated useful life of between 5 and 15 years using a straight-line method or, if reliably determinable, based on the pattern in which the economic benefits of the assets are expected to be consumed. Amortization expense decreased in the current three and six month periods compared to the corresponding periods in the prior year primarily due to lower amortization of intangible assets as a result of an impairment in the prior year related to the Mobidiag acquisition and the disposition of the SSI ultrasound business as of the beginning of the first quarter of fiscal 2024.

Impairment of Intangible Asset. During the second quarter of fiscal 2024, in connection with commencing our company-wide annual strategic planning process, we identified indicators of impairment in our BioZorb product line, which

35

was part of the Focal acquisition. As a result, we performed an undiscounted cash flow analysis pursuant to ASC 360, Property, Plant and Equipment - Overall, to determine if the cash flows expected to be generated by the BioZorb product line over the remaining estimated useful life of the primary asset were sufficient to recover the carrying value of the asset group. Based on this analysis the undiscounted cash flows were not sufficient to recover the carrying value of the long-lived assets. Therefore, we were required to perform Step 3 of the impairment test and determine the fair value of the asset group. To estimate the fair value of the asset group, we utilized the income approach, which is based on a discounted cash flow (DCF) analysis and calculated the fair value by estimating the after-tax cash flows attributable to the asset group and then discounting the after-tax cash flows to present value using a risk-adjusted discount rate. Based on this analysis, the fair value of the BioZorb asset group was below its carrying value, and we recorded an impairment charge of $26.8 million of which $25.9 million was allocated to developed technology.

Service and other revenues gross margin increased to 49.4% and 49.6%, respectively, in the current three and six month periods compared to 49.0% and 46.7%, respectively, in the corresponding periods in the prior year. The increase in gross margin in the current three and six month periods was primarily due to an increase in lab testing revenue from Biotheranostics, which has higher margins than our legacy service business, and a decrease in spare parts sales in Breast Health which have lower gross margins. The increase in gross margin in the current six months was also due to a decrease in service department costs related to the extra week in the prior year period.

** Percentage not meaningful

Research and Development Expenses. Research and development expenses increased 0.8% in the current three month period compared to the corresponding period in the prior year primarily due to a $10.0 million charge related to the purchase of intellectual property to be used in a development project in Diagnostics that has no future alternative use and a decrease in credits recorded for funds received from the Biomedical Advanced Research and Development Authority (BARDA) grant to

36

obtain FDA approval of our SARS-CoV-2 assays partially offset by a decrease in project spend, a decrease in compensation and benefits as a result of lower headcount, primarily in Breast Health, and the elimination of expenses from SSI of $3.1 million from its disposal. Research and development expenses decreased 5.0% in the current six month period compared to the corresponding period in the prior year primarily due to a decrease in project spend, a decrease in compensation and benefits from lower headcount, primarily in Breast Health, as well as the extra week in the prior year six month period, and the elimination of expenses from SSI of $5.9 million from its disposal. These decreases were partially offset by the $10.0 million charge for purchased intellectual property and a decrease in BARDA credits. At any point in time, we have a number of different research projects and clinical trials being conducted and the timing of these projects and related costs can vary from period to period.

Selling and Marketing Expenses. Selling and marketing expenses increased 1.3% in the current three month period compared to the corresponding period in the prior year primarily due to an increase in compensation and benefits from an increase in headcount internationally partially offset by the elimination of expenses from SSI of $1.6 million. Sales and marketing expenses decreased 4.2% in the current six month period compared to the corresponding period in the prior year primarily due to lower spending on advertising and marketing initiatives, primarily from our sponsorship of the Women’s Tennis Association, a decrease in compensation and benefits as a result of additional expenses from the extra week in the prior year period and lower severance expense and the elimination of expenses from SSI of $3.7 million, partially offset by higher commissions in our Breast Health division from an increase in sales.

General and Administrative Expenses. General and administrative expenses decreased 0.4% in the current three month period compared to the corresponding period in the prior year primarily due to a decrease of $5.0 million in charitable contributions, a decrease in consulting spend and a decrease in legal expenses, partially offset by an increase in compensation and benefits from higher stock compensation expense and higher deferred compensation plan expense. General and administrative expenses increased 1.4% in the current six month period compared to the corresponding period in the prior year primarily due to an increase in compensation and benefits from higher stock compensation expense as a result of the equity plan’s retirement provisions, higher expense from our deferred compensation plan, an increase in legal expenses as the prior year period included a benefit of $7.4 million from receiving the settlement awarded in the Minerva litigation and an increase in bad debt expense of $3.6 million. These increases were partially offset by a decrease in charitable donations of $10.0 million, an $8.9 million charge for a business dispute in connection with terminating the Mobidiag joint venture agreement in China in the prior year period and lower IT infrastructure spend from one less week of activity.

Amortization of Intangible Assets. Amortization of intangible assets primarily results from customer relationships and trade names related to our acquisitions. These intangible assets are generally amortized over their estimated useful lives of between 5 and 30 years using a straight-line method or, if reliably determinable, based on the pattern in which the economic benefits of the assets are expected to be consumed utilizing expected undiscounted future cash flows. Amortization expense decreased in the current three month period compared to the corresponding period in the prior year primarily due to lower Mobidiag intangible asset values from impairment charges recorded in the third quarter of fiscal 2023 and accelerated amortization recorded in the first quarter of fiscal 2024. Amortization expense increased in the current six month period compared to the corresponding period in the prior year primarily due to accelerated amortization of customer relationship and trade name intangible assets acquired in the Mobidiag acquisition.

Impairment of Intangible Assets. During the second quarter of fiscal 2024, as discussed above, we recorded an impairment charge of $26.8 million related to our BioZorb product line of which $0.9 million was allocated to trade names and written off to operating expenses. During the first quarter of fiscal 2024, as discussed in Note 4 to the consolidated financial statements, we recorded an impairment charge of $4.3 million to record our only IPR&D asset from the Mobidiag acquisition to fair value. The reduction in fair value was primarily due to a reduction in forecasted revenues and timing of completing the project.

Contingent Consideration Fair Value Adjustments. In connection with the acquisition of Acessa Health Inc., or Acessa, we were obligated to make contingent earn-out payments based on achieving incremental revenue growth over a three-year period ending annually in December of each of 2021, 2022, and 2023. As of the acquisition date, we recorded a contingent consideration liability for the estimated fair value of the amount we expected to pay to the former shareholders of the acquired business. As of the end of the first quarter of fiscal 2024, the third and final measurement period was completed, and we recorded a loss of $1.7 million to increase the contingent consideration liability to fair value based on actual revenue results in the final earn-out period. During the second quarter of fiscal 2023, we updated our forecasted revenue and recorded a gain of $12.4 million to record the liability at its fair value. The reduction in fair value was due to a decrease in forecasted revenues over the remaining measurement period at that time.

37

Restructuring Charges. During the first quarter of fiscal 2024, we further refined our strategy for the Mobidiag business, which is within the Diagnostics reportable segment. The strategy change included the decision to discontinue the manufacture and sale of certain products, closure of facilities in Finland and France, and to move the development activities and operations to our San Diego, California location. As such, we determined certain fixed assets lives should be shortened and that lease assets were impaired at the affected facilities and recorded accelerated depreciation of $7.2 million and a lease asset impairment charge of $12.5 million. In addition, during the first quarter of fiscal 2024, we recorded the minimum statutory severance benefit for the affected French employees of $1.8 million. During the second quarter of fiscal 2024, we finalized negotiations with the respective Works Councils. We estimate that the total charge for severance benefits will be approximately $12.2 million, the majority of which will be recognized over the service period to receive such benefits. In the second quarter of fiscal 2024, we recorded severance charges of $4.0 million related to this action. This action is expected to be completed by the second quarter of fiscal 2025. For additional information, please refer to Note 8 to our consolidated financial statements.

Interest expense consists primarily of the cash interest costs and the related amortization of the debt discount and deferred issuance costs on our outstanding debt. Interest expense increased in the current three and six month periods compared to the corresponding periods in the prior year, primarily due the increase in the variable interest rate under our 2021 Credit Agreement and a decrease in amounts received under interest rate swap agreements primarily due to a decrease in our overall hedged principal amount from $1.0 billion to $500 million. These decreases were partially offset by a lower principal balance outstanding under our 2021 Credit Agreement as we voluntarily prepaid $250.0 million during the first quarter of fiscal 2024.

For the current six month period, this account primarily consisted of a gain of $10.0 million from the change in cash surrender value of life insurance contracts related to our deferred compensation plan driven by stock market gains. This gain was partially offset by net foreign currency exchange losses of $7.6 million primarily from the mark-to-market of foreign currency contracts used to hedge operating results and a $1.4 million ownership share loss from our investment in Maverix Medical. For the corresponding six month period in the prior year, this account primarily consisted of net foreign currency exchange losses of $18.4 million, primarily from the mark-to-market of foreign currency contracts used to hedge operating results, partially offset by a gain of $5.3 million from the change in cash surrender value of life insurance contracts related to our deferred compensation plan driven by stock market gains.

Our effective tax rates for the three and six months ended March 30, 2024 were 19.7% and (3.4)%, respectively, compared to 21.8% and 21.7% for the corresponding periods in the prior year.

Our effective tax rate for the three months ended March 30, 2024 was lower than the U.S. statutory tax rate primarily due to the U.S. deduction for foreign derived intangible income, and the geographic mix of income earned by the Company’s international subsidiaries, which are generally taxed at rates lower than the U.S. statutory tax rate. Our effective tax rate for the six months ended March 30, 2024 was lower than the U.S. statutory tax rate primarily due to a discrete tax benefit of $107.2 million related to a worthless stock deduction on the investment in one of our international subsidiaries recorded in the first quarter of fiscal 2024, the U.S. deduction for foreign derived intangible income, and the geographic mix of income earned by the Company’s international subsidiaries, which are generally taxed at rates lower than the U.S. statutory tax rate.

Our effective tax rates for the three and six months ended April 1, 2023 were slightly higher than the U.S. statutory tax rate primarily due to increases in income tax reserves, the global intangible low-taxed income inclusion, and state income taxes, partially offset by the impact of the U.S. deduction for foreign derived intangible income, the geographic mix of income earned by our international subsidiaries, which are generally taxed at rates lower than the U.S. statutory tax rate, and federal and state tax credits.

Segment Results of Operations

We operate in four segments: Diagnostics, Breast Health, GYN Surgical and Skeletal Health. The accounting policies of the segments are the same as those described in the Notes to the Consolidated Financial Statements included in our Annual Report on Form 10-K for the fiscal year ended September 30, 2023. We measure segment performance based on total revenues and operating income. Revenues from product sales of each of these segments are described in further detail above. The discussion that follows is a summary analysis of total revenues and the primary changes in operating income or loss by segment.

Diagnostics revenues decreased in the current three and six month periods compared to the corresponding periods in the prior year primarily due to the decrease in product revenues discussed above, partially offset by higher lab testing revenue from our Biotheranostics business.

Operating income for this business segment decreased in the current three and six month periods compared to the corresponding periods in the prior year primarily due to a decrease in gross profit from lower COVID-19 assay sales and to a lesser extent an increase in operating expenses. Gross margin was 51.5% and 51.8% in the current three and six month periods, respectively, compared to 55.0% and 56.6% in the corresponding periods in the prior year, respectively. The decrease in gross margin in the current three and six month periods was primarily due to lower sales volumes of our SARS-CoV-2 assays, which have a higher margin, unfavorable manufacturing variances and higher sales volumes of our instruments which have a lower margin. These decreases were partially offset by lower intangible asset amortization, a decrease in scrap, lower inventory reserves, an increase in Biotheranostics lab testing revenue which has higher margins and increases in our Women's Health Aptima and Fusion respiratory assay sales, and an increase in ThinPrep pap tests in the current three month period.

Operating expenses increased in the current three month period compared to the corresponding period in the prior year primarily due to a $10.0 million charge related to the purchase of intellectual property to be used in a development project that has no future alternative use, an increase in restructuring charges of $4.2 million related to Mobidiag and lower BARDA credits partially offset by a decrease in research and development project spend and lower allocated charitable donations and marketing initiative spend. Operating expenses increased in the current six month period compared to the corresponding period in the prior year primarily due to restructuring charges of $26.3 million related to Mobidiag, the $10.0 million charge for purchased intellectual property, accelerated amortization of acquired intangibles of $7.3 million, an impairment charge of $4.3 million related to the in-process research and development intangible asset, higher corporate allocations from an increase in stock compensation and expenses from our deferred compensation plan, an increase in bad debt expense and lower BARDA credits. Partially offsetting these increases was the prior year period included a charge of $8.9 million related to the termination of the Mobidiag joint venture in China, a decrease in sales and use tax charges, lower severance, a decrease in marketing initiatives and allocated charitable contributions and the prior year six month period included an additional week of expenses.

Operating Income as a % of Segment Revenue	23.8		%	28.5		%					25.4		%	23.7		%

Breast Health revenues decreased in the current three month period compared to the corresponding period in the prior year due to a decrease in service revenue, partially offset by an increase in product revenues as discussed above. Revenue increased in the current six month period compared to the corresponding period in the prior year due to an increase in product revenues as discussed above.

Operating income for this business segment decreased in the current three month period compared to the corresponding period in the prior year primarily due to a decrease in gross profit partially offset by a decrease in operating expenses. The decrease in gross profit was primarily due to the BioZorb intangible asset impairment charge of $25.9 million, partially offset by an increase in product sales and a decrease in intangible asset amortization from the disposition of the SSI business at the beginning of fiscal 2024. Gross margin was 51.6% in the current three month period compared to 57.3% in the corresponding period in the prior year. This decrease was primarily due to the BioZorb intangible asset impairment charge. Operating income increased in the current six month period compared to the corresponding period in the prior year primarily due to an increase in gross profit and a decrease in operating expenses. Gross margin was 54.2% in the current six month period compared to 55.8% in the corresponding period in the prior year. The decrease in gross margin was primarily due to the BioZorb intangible asset impairment charge and to a lesser extent the decrease in service revenues, partially offset by an increase in product sales, decrease in acquired intangible asset amortization due to impairments in the prior year and improved manufacturing utilization.

Operating expenses decreased in the current three and six month periods compared to the corresponding periods in the prior year primarily due to the elimination of $6.0 million and $12.4 million, respectively, of expenses from the SSI disposition, lower compensation from a reduction in headcount in research and development, a decrease in allocated charitable contributions

40

and marketing initiatives and a decrease in compensation and benefits from the extra week in the prior year six month period. Partially offsetting these decreases in the current six month period was an increase in employee commissions related to the increase in product sales and an increase in transaction expenses.

GYN Surgical revenues increased in the current three and six month periods compared to the corresponding periods in the prior year primarily due to the increase in product revenues discussed above.

Operating income for this business segment decreased in the current three and six month periods compared to the corresponding periods in the prior year primarily due to an increase in operating expenses partially offset by an increase in gross profit. Gross margin was 65.9% and 66.8% in the current three and six month periods, respectively, compared to 67.9% and 68.3%, in the corresponding periods in the prior year, respectively. The decrease in gross margin was primarily due to higher volume sales of Fluent Fluid Management systems and lower volumes of our NovaSure devices, partially offset by an increase in MyoSure devices, which have higher margins.

Operating expenses increased in the current three and six month periods compared to the corresponding periods in the prior year primarily due to a gain of $12.4 million recorded in the prior year period to decrease the Acessa contingent consideration liability to fair value, a $7.4 million settlement awarded to us in the Minerva litigation in the prior year, and an increase in bad debt expense in the current six month period. Partially offsetting these increases was a decrease in commissions expense and research and development project spend.

Skeletal Health revenues decreased in the current three and six month periods compared to the corresponding periods in the prior year primarily due to the decrease in product revenues discussed above.

Operating income for this business segment decreased in the current three month period compared to the corresponding periods in the prior year primarily due to a decrease in gross profit partially offset by a decrease in operating expenses. Operating income was flat in the current six month period compared to the corresponding period in the prior year primarily due to a decrease in operating expenses offset by a decrease in gross profit. Gross margin was 34.2% and 36.3% in the current three and six month periods, respectively, compared to 35.6% and 33.0% in the corresponding periods in the prior year, respectively. The decrease in gross margin in the current three month period compared to the corresponding period in the prior year was primarily due to lower Horizon DXA and Insight FD volumes. The increase in gross margin in the current six month period compared to the corresponding period in the prior year was primarily due to a decrease in volumes of Insight FD, which has lower margins, and an increase in service contract revenue.

41

Operating expenses decreased in the current three and six month periods compared to the corresponding periods in the prior year primarily due to a decrease in third-party commissions and in the current six month period a decrease in compensation and benefits from the extra week in the prior year period.

LIQUIDITY AND CAPITAL RESOURCES

At March 30, 2024, we had $2,834.1 million of working capital and our cash and cash equivalents totaled $2,180.0 million. Our cash and cash equivalents decreased by $575.7 million during the first six months of fiscal 2024 primarily due to cash used in investing and financing activities primarily related to repurchases of our common stock and debt repayments, partially offset by cash generated from operating activities.

In the first six months of fiscal 2024, our operating activities provided cash of $512.4 million, primarily due to net income of $416.4 million, non-cash charges for depreciation and amortization aggregating $162.1 million, stock-based compensation expense of $54.5 million, intangible asset impairment charges of $31.1 million and lease asset impairment charges of $12.5 million. These adjustments to net income were partially offset by a decrease in net deferred income taxes of $46.8 million primarily due to the capitalization of research expenditures under the tax rules and to a lesser extent the amortization of intangible assets. Cash provided by operations included a net cash outflow of $129.6 million from changes in our operating assets and liabilities. This cash outflow was primarily driven by an increase in prepaid income taxes of $115.3 million primarily due to a worthless stock deduction and to a lesser extent the timing of tax payments relative to the provision for income taxes, an increase in inventory of $30.4 million to meet expected demand across our primary product lines and the build of Breast Health capital equipment prior to the transfer of manufacturing to Newark, Delaware from Danbury, Connecticut, an increase of $20.1 million in accounts receivable due to higher sales in the second quarter of fiscal 2024 compared to the fourth quarter of fiscal 2023 as our days sales outstanding remained consistent, and a $12.5 million increase in prepaid expenses and other assets primarily due to our Women’s Tennis Association sponsorship. These cash outflows were partially offset by an increase of $26.7 million in accounts payable primarily due to the timing of payments.

In the first six months of fiscal 2024, our investing activities used cash of $142.7 million primarily due to capital expenditures of $66.0 million, which primarily consisted of the placement of equipment under customer usage agreements and purchase of manufacturing equipment and building improvements at our Newark and San Diego facilities, $39.5 million for strategic investments and a $31.3 million net payment to sell our SSI ultrasound business.

In the first six months of fiscal 2024, our financing activities used cash of $948.0 million primarily due to $676.8 million for repurchases of our common stock, including a $500 million accelerated share repurchase program, $268.8 million for debt principal payments under our 2021 Credit Agreement, including a $250.0 million voluntary prepayment, and $16.3 million for the payment of employee taxes withheld for the net share settlement of vested restricted stock units. Partially offsetting these uses of cash were proceeds of $18.4 million from our equity plans.

We had total recorded debt outstanding of $2.55 billion at March 30, 2024, which was comprised of amounts outstanding under our 2021 Credit Agreement of $1.21 billion (principal of $1.22 billion), 2029 Senior Notes of $939.8 million (principal of $950.0 million), and 2028 Senior Notes of $397.2 million (principal of $400.0 million).

2021 Credit Agreement

On September 27, 2021, we refinanced our then existing term loan and revolving credit facility with Bank of America, N.A. in its capacity as Administrative Agent, Swing Line Lender and L/C Issuer, and certain other lenders (the “2018 Credit Agreement”) by entering into a Refinancing Amendment (the “2021 Credit Agreement”). Borrowings under the 2021 Credit Agreement are secured by first-priority liens on, and a first priority security interest in, substantially all of our and our Subsidiary Guarantors’ U.S. assets. The credit facilities (the “2021 Credit Facilities”) under the 2021 Credit Agreement consist of:

•A secured term loan in the initial principal amount of $1.5 billion (“2021 Term Loan”) with a stated maturity date of September 25, 2026; and

•A secured revolving credit facility (the “2021 Revolver”) under which the Borrowers may borrow up to $2.0 billion, subject to certain sublimits, with a stated maturity date of September 25, 2026.

As of March 30, 2024, there were no borrowings under the 2021 Revolver.

42

Borrowings under the 2021 Credit Agreement bear interest, at our option, at the Base Rate, at the Term SOFR Rate, at the Alternative Currency Daily Rate, or at the Daily SOFR Rate, in each case plus the Applicable Rate. The Applicable Rate in regard to the Base Rate, the Term SOFR Rate, the Alternative Currency Daily Rate, the Alternative Currency Term Rate and the Daily SOFR Rate is subject to change depending on the Total Net Leverage Ratio (as defined in the 2021 Credit Agreement). As of March 30, 2024, the interest rate under the 2021 Term Loan was 6.43% per annum.

We are required to make scheduled principal payments under the 2021 Term Loan in increasing amounts, which currently range from $9.375 million per three-month period to $18.75 million per three-month period commencing with the three-month period ending on December 26, 2025. The remaining scheduled balance of $1.085 billion (or such lesser aggregate principal amount of the Term Loans then outstanding) on the 2021 Term Loan and any amounts outstanding under the 2021 Revolver are due at their respective maturities. In addition, subject to the terms and conditions set forth in the 2021 Credit Agreement, we may be required to make certain mandatory prepayments from the net proceeds of specified types of asset sales (subject to certain reinvestment rights), debt issuances (excluding permitted debt) and insurance recoveries (subject to certain reinvestment rights). Certain mandatory prepayments are subject to reduction or elimination if certain financial covenants are met. Subject to certain limitations, we may voluntarily prepay any of the 2021 Credit Facilities without premium or penalty. As of March 30, 2024, the outstanding principal balance of the 2021 Term Loan was $1.2 billion.

The 2021 Credit Agreement contains affirmative and negative covenants customarily applicable to senior secured credit facilities, including the requirement that we maintain two financial ratios (a total net leverage ratio and an interest coverage ratio) measured as of the last day of each quarter for the previous twelve-month period. As of March 30, 2024, we were in compliance with these covenants.

2028 Senior Notes

The total aggregate principal balance of the 2028 Senior Notes is $400.0 million. The 2028 Senior Notes are general senior unsecured obligations and are guaranteed on a senior unsecured basis by certain of our domestic subsidiaries. The 2028 Senior Notes mature on February 1, 2028 and bear interest at the rate of 4.625% per year, payable semi-annually on February 1 and August 1 of each year. We have the option to redeem the 2028 Senior Notes on or after: February 1, 2024 through February 1, 2025 at 101.541% of par; February 1, 2025 through February 1, 2026 at 100.770% of par; and February 1, 2026 and thereafter at 100% of par. In addition, if there is a change of control coupled with a decline in ratings, as provided in the indenture, we will be required to make an offer to purchase each holder’s 2028 Senior Notes at a price equal to 101% of their principal amount, plus accrued and unpaid interest, if any, to the repurchase date.

43

2029 Senior Notes

The total aggregate principal balance of the 2029 Senior Notes is $950.0 million. The 2029 Senior Notes are general senior unsecured obligations and are guaranteed on a senior unsecured basis by certain domestic subsidiaries. The 2029 Senior Notes mature on February 15, 2029 and bear interest at the rate of 3.250% per year, payable semi-annually on February 15 and August 15 of each year. We have the option to redeem the 2029 Senior Notes on or after: September 28, 2023 through September 27, 2024 at 101.625% of par; September 28, 2024 through September 27, 2025 at 100.813% of par; and September 28, 2025 and thereafter at 100% of par. In addition, if there is a change of control coupled with a decline in ratings, as provided in the indenture, we will be required to make an offer to purchase each holder’s 2029 Senior Notes at a price equal to 101% of their principal amount, plus accrued and unpaid interest, if any, to the repurchase date.

Stock Repurchase Program

On September 22, 2022, the Board of Directors authorized a stock repurchase program, with a five-year term, to repurchase up to $1.0 billion of our outstanding common stock, effective as of the close of trading September 23, 2022. This repurchase program replaced the previous $1.0 billion authorization. As of March 30, 2024, $348.6 million remained available under this authorization.

The timing of the share repurchases will be based upon our continuing analysis of market, financial, and other factors. Repurchases under the authorized share repurchase plan may be made using a variety of methods, which may include, but are not limited to, open market purchases, privately negotiated transactions, accelerated share repurchase agreements, or purchases pursuant to a Rule 10b5-1 plan under the Exchange Act. The authorized share repurchase plan may be suspended, delayed or discontinued at any time.

Acquisition

On April 26, 2024, we executed an agreement to acquire Endomagnetics Ltd (“Endomag”) for a purchase price of approximately $310.0 million, subject to working capital and other customary adjustments. The closing is subject to certain regulatory approvals. Endomag, located in the UK, develops and sells breast surgery localization and lymphatic tracing technologies.

Legal Contingencies

We are currently involved in several legal proceedings, claims, governmental and/or regulatory inspections, inquiries and investigations arising out of the ordinary course of our business. In connection with these legal proceedings, claims, inspections, inquiries or investigations, management periodically reviews estimates of potential costs to be incurred by us in connection with the adjudication or settlement, if any, of these proceedings. These estimates are developed, as applicable in consultation with outside counsel, and are based on an analysis of potential litigation outcomes and settlement strategies. In accordance with ASC 450, Contingencies, loss contingencies are accrued if, in the opinion of management, an adverse outcome is probable and such financial outcome can be reasonably estimated. It is possible that future results for any particular quarter or annual period may be materially affected by changes in our assumptions or the effectiveness of our strategies relating to these proceedings. Information with respect to this disclosure may be found in Note 12 to the Consolidated Financial Statements in this Quarterly Report on Form 10-Q, which information is incorporated herein by reference.

Future Liquidity Considerations

We expect to continue to review and evaluate potential strategic transactions that we believe will complement our current or future business. Subject to the “Risk Factors,” if any, set forth or incorporated by reference in Part II, Item 1A of this Quarterly Report on Form 10-Q, as well as those described in Part I, Item 1A of our Annual Report on Form 10-K for the fiscal year ended September 30, 2023 or any other of our subsequently filed reports, and the general disclaimers set forth in our “Cautionary Statement” regarding forward-looking statements at the outset of this Item 2, we believe that our cash and cash equivalents, including marketable securities, cash flows from operations, and the cash available under our 2021 Revolver will provide us with sufficient funds in order to fund our expected normal operations and debt payments over the next twelve months. Our longer-term liquidity is contingent upon future operating performance. We may also require additional capital in the future to fund capital expenditures, repayment of debt, acquisitions, strategic transactions or other investments. As described above, we have significant indebtedness outstanding under our 2021 Credit Agreement, 2028 Senior Notes, and 2029 Senior Notes. These capital requirements could be substantial. For a description of risks to our operating performance and our indebtedness, see the “Risk Factors” set forth or incorporated by reference in Part II, Item 1A of this Quarterly Report on Form

10-Q, as well as those described in Part I, Item 1A of our Annual Report on Form 10-K for the fiscal year ended September 30, 2023.

CRITICAL ACCOUNTING POLICIES AND ESTIMATES

The discussion and analysis of our financial condition and results of operations are based upon our interim consolidated financial statements, which have been prepared in accordance with U.S. generally accepted accounting principles. The preparation of these consolidated financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent assets and liabilities. On an on-going basis, we evaluate our estimates, including those related to revenue recognition for multiple element arrangements, allowance for doubtful accounts, reserves for excess and obsolete inventories, valuations, purchase price allocations and contingent consideration related to business combinations, expected future cash flows including growth rates, discount rates, terminal values and other assumptions used to evaluate the recoverability of long-lived assets and goodwill, estimated fair values of intangible assets and goodwill, amortization methods and periods, warranty reserves, certain accrued expenses, restructuring and other related charges, stock-based compensation, contingent liabilities, tax reserves and recoverability of our net deferred tax assets and related valuation allowances. We base our estimates on historical experience and various other assumptions that are believed to be reasonable under the circumstances. Actual results could differ from these estimates if past experience or other assumptions do not turn out to be substantially accurate. Any differences may have a material impact on our financial condition and results of operations. For a discussion of how these and other factors may affect our business, see the “Cautionary Statement” regarding forward-looking statements set forth at the outset of this Item 2 and the “Risk Factors” set forth or incorporated by reference in Part II, Item 1A of this Quarterly Report on Form 10-Q as well as those described in Part I, Item 1A of our Annual Report on Form 10-K for the fiscal year ended September 30, 2023 or any other of our subsequently filed reports.

The critical accounting estimates that we believe affect our more significant judgments and estimates used in the preparation of our consolidated financial statements presented in this report are described in Management’s Discussion and Analysis of Financial Condition and Results of Operations and in the Notes to the Consolidated Financial Statements included in our Annual Report on Form 10-K for the fiscal year ended September 30, 2023. There have been no material changes to our critical accounting policies or estimates from those set forth in our Annual Report on Form 10-K for the fiscal year ended September 30, 2023.

Item 3.    Quantitative and Qualitative Disclosures About Market Risk.

Financial Instruments, Other Financial Instruments, and Derivative Commodity Instruments. Financial instruments consist of cash and cash equivalents, including money market funds, United States Treasury bills and commercial paper, accounts receivable, equity investments, foreign currency derivative contracts, interest rate swap agreements, insurance contracts, accounts payable and debt obligations. Except for our outstanding 2028 and 2029 Senior Notes, the fair value of these financial instruments approximate their carrying amount. The fair values of our 2028 and 2029 Senior Notes were approximately $385.9 million and $852.6 million, respectively, as of March 30, 2024. Amounts outstanding under our 2021 Credit Agreement of $1.2 billion aggregate principal as of March 30, 2024 are subject to variable rates of interest based on current market rates, and as such, we believe the carrying amount of these obligations approximates fair value.

Primary Market Risk Exposures. Our primary market risk exposure is in the areas of interest rate risk and foreign currency exchange rate risk as well as our investments in money market funds, United States Treasury bills and commercial paper. We consider these investments to be low risk as they are highly rated securities, highly liquid and short term in nature. We incur interest expense on borrowings outstanding under our 2028 and 2029 Senior Notes, and 2021 Credit Agreement. The 2028 and 2029 Senior Notes have fixed interest rates. Borrowings under our 2021 Credit Agreement bear interest at the SOFR Rate plus SOFR Adjustment of 0.10% plus the applicable margin of 1.00% per annum.

As of March 30, 2024, there was $1.2 billion of aggregate principal outstanding under the 2021 Credit Agreement. Since this debt obligation is a variable rate instrument, our interest expense associated with the instrument is subject to change. A hypothetical 10% adverse movement (increase in the SOFR rate) would increase annual interest expense by approximately $3.8 million, which is net of the impact of our interest rate swap hedge. We previously entered into interest rate swap agreements to help mitigate the interest rate volatility associated with the variable rate interest on the amounts outstanding under our credit facilities. The critical terms of the interest rate swaps were designed to mirror the terms of our SOFR-based borrowings under the 2021 Credit Agreement, and therefore the interest rate swap is highly effective at offsetting the cash flows being hedged. We designated these derivative instruments as a cash flow hedge of the variability of the Term SOFR-based interest payments on $500 million of principal.

45

The return from cash and cash equivalents, including marketable securities, will vary as short-term interest rates change. A hypothetical 10% increase in market interest rates would increase annual interest income by approximately $9.4 million based on our current cash balances.

Foreign Currency Exchange Risk. Our international business is subject to risks, including, but not limited to unique economic conditions, changes in political climate, differing tax structures, other regulations and restrictions, and foreign exchange rate volatility. Accordingly, our future results could be materially adversely impacted by changes in these or other factors.

We conduct business worldwide and maintain sales and service offices outside the U.S. as well as manufacturing facilities in Costa Rica and the United Kingdom. Our international sales are denominated in a number of currencies, primarily the Euro, U.S. dollar, UK Pound, Australian dollar, Canadian dollar, Chinese Yuan and Japanese Yen. The majority of our foreign subsidiaries functional currency is the local currency, although certain foreign subsidiaries functional currency is the U.S. dollar based on the nature of their operations or functions. Our revenues denominated in foreign currencies are positively affected when the U.S. dollar weakens against them and adversely affected when the U.S. dollar strengthens. Fluctuations in foreign currency rates could affect our sales, cost of goods and operating margins and could result in exchange losses. In addition, currency devaluations can result in a loss if we hold deposits in that currency. We have executed forward foreign currency contracts to hedge a portion of results denominated in the Euro, UK Pound, Australian dollar, Japanese Yen, Canadian dollar and Chinese Yuan. These contracts do not qualify for hedge accounting. As a result, we may experience volatility in our Consolidated Statements of Income due to (i) the impact of unrealized gains and losses reported in other income (expense), net on the mark-to-market of outstanding contracts and (ii) realized gains and losses recognized in other income (expense), net, whereas the offsetting economic gains and losses are reported in the line item of the underlying cash flow, for example, revenue.

We believe that the operating expenses of our international subsidiaries that are incurred in local currencies will not have a material adverse effect on our business, results of operations or financial condition. Our operating results and certain assets and liabilities that are denominated in foreign currencies are affected by changes in the relative strength of the U.S. dollar against those currencies. Our expenses, denominated in foreign currencies, are positively affected when the U.S. dollar strengthens against those currencies and adversely affected when the U.S. dollar weakens. However, we believe that the foreign currency exchange risk is not significant. We believe a hypothetical 10% increase or decrease in foreign currencies that we transact in would not have a material adverse impact on our financial condition or results of operations.

Item 4.    Controls and Procedures.

We maintain disclosure controls and procedures that are designed to ensure that information required to be disclosed in our Exchange Act reports is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms, and that such information 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. In designing and evaluating the disclosure controls and procedures, management recognized that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives, as ours are designed to do, and management necessarily was required to apply its judgment in evaluating the cost-benefit relationship of possible controls and procedures.

As of March 30, 2024, we carried out an evaluation, under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of our disclosure controls and procedures, as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act. Based upon that evaluation, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures are effective as of March 30, 2024.

An evaluation was also performed under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, of any change in our internal control over financial reporting that occurred during our last fiscal quarter that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting. That evaluation did not identify any change in our internal control over financial reporting that occurred during our latest fiscal quarter that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

As of March 30, 2024, $348.5 million remained unused under this program. The program does not obligate the Company to acquire a minimum amount of shares. Under the program, shares may be repurchased in privately negotiated and/or open market transactions, including under plans complying with Rule 10b5-1 under the Exchange Act. For additional information regarding the Company’s repurchase programs, please see “Management's Discussion and Analysis of Financial Condition and Results of Operations – Liquidity and Capital Resources – Stock Repurchase Program.”

(2)On November 15, 2023, the Company entered into a share repurchase (“ASR”) agreement with Goldman Sachs. Under the ASR, Hologic agreed to purchase $500 million of Hologic’s common stock. The initial delivery was 5.6 million shares, representing 80% of the transaction value based on the Company’s closing share price on November 14, 2023. The final settlement occurred during the second quarter of fiscal 2024 as 1.4 million additional shares were received on February 27, 2024 under the ASR agreement. The number of shares was determined upon completion of the transaction and was based on the total transaction value and the volume-weighted average share price of our common stock during the term of the agreement. The volume-weighted average share price under the ASR was $71.55.

Item 5. Other Information

Rule 10b5-1 Trading Plans

During the second quarter of fiscal 2024, Christiana Stamoulis, a member of our Board of Directors, adopted a trading plan intended to satisfy Rule 10b5-1(c) under the Exchange Act on February 16, 2024 to sell up to 16,441 shares of our common stock (following the exercise of options) between May 21, 2024 and January 3, 2025, the date this plan expires. The trading plan will cease upon the earlier of January 3, 2025 or the sale of all shares subject to the trading plan.

During the second quarter of fiscal 2024, none of our other directors or executive officers adopted Rule 10b5-1 trading plans and none of our directors or executive officers terminated a Rule 10b5-1 trading plan or adopted or terminated a non-Rule 10b5-1 trading arrangement (as defined in Item 408(c) of Regulation S-K).

Exhibit 10.1

TRANSITION AGREEMENT

AGREEMENT entered into as of this 31st day of December, 2023 by and between Hologic, Inc., a Delaware corporation with its principal place of business at 250 Campus Drive, Massachusetts 01752 (the “Company”), and Elisabeth (Lisa) A. Hellmann, an individual having her principal residence in Del Mar, California (the “Executive”).

WHEREAS, capitalized terms used but not defined herein shall have the meanings provided in the Severance Agreement;

WHEREAS, the Company has notified the Executive that it intends to terminate the Executive’s employment with the Company without Cause; and

WHEREAS, the Executive and the Company desire to provide for an amicable separation to their mutual benefit on the terms and conditions set forth herein.

NOW, THEREFORE, in consideration of the mutual covenants and agreements hereinafter set forth, the parties hereto, each intending to be legally bound, do hereby agree as follows:

1.Termination as Executive.

(a)Transition Date. Effective on January 1, 2024 (the “Transition Date”), without any further notice required of the Company or the Executive, the Executive shall be terminated by the Company from her position as Senior Vice President, Human Resources and Corporate Communications of the Company, as well as any and all positions held by her including, without limitation, as an employee, officer, director, manager, or member, as applicable, of the Company and all direct or indirect subsidiaries of the Company without Cause. Nothing herein shall preclude the Executive from resigning or the Company from terminating the Executive from any positions prior to the Transition Date.

(b)Duties. Prior to the Transition Date, the Executive shall continue to serve as Senior Vice President, Human Resources and Corporate Communications of the Company, with all the responsibilities and duties associated with such position.

(c)Compensation.

stock units, if any, will continue to vest in accordance with and subject to the terms and conditions set forth in the applicable equity incentive plans and award agreements; and (iii) the Executive shall be entitled to participate in any and all retirement (both qualified and non-qualified), vacation and/or sick pay, medical, dental, life insurance and other employee benefit plans in which she currently participates, all to the extent the Executive remains eligible under the terms of such plans and subject to the terms and conditions of such plans as may be in effect from time to time, including (without limitation) the Company’s car allowance program. On the Transition Date, the Executive will receive her final paycheck with accrued and unpaid pay through that date as well as accrued and unpaid vacation time and payment of all outstanding business expense reimbursements according to Company policy.

2.Separation Benefits.

(a)Separation Benefits. As a consequence of the termination of the Executive’s employment as contemplated herein and in full discharge of the Company’s obligations due to the Executive thereunder, subject to (x) Executive executing this Agreement and executing the Release Agreement attached hereto as Exhibit A (the “Release”) within twenty-one (21) days of the Transition Date, (y) the Release becoming effective and irrevocable in accordance with its terms, and (z) Executive’s compliance with the terms and conditions of this Transition Agreement (including pursuant to Section 4 below), the Company shall pay to the Executive or her heirs or estate, if applicable, the following (the “Severance Amount”): (i) the Executive’s Annual Base Salary for twelve (12) months following the Transition Date, payable in accordance with the Company’s normal payroll practices; (ii) the Executive’s Average Annual Bonus, payable in accordance with the Company’s normal payroll practices; (iii) an amount equal to the product of (A) the Highest Annual Bonus and (B) a fraction, the numerator of which is the number of days in the current fiscal year through the Transition Date, and the denominator of which is 365, payable in lump sum; (iv) a cash payment in lieu of Welfare Benefit Continuation to the Executive and her family for twelve (12) months following the Transition Date, payable in lump sum. In addition, subject to the conditions in clauses (x) – (z) of the preceding sentence, the Company shall take all necessary action to provide that all of the Executive’s accounts under the Company’s Amended and Restated Deferred Compensation Program (the “DCP”) shall be fully vested (or equivalent treatment) as of the Transition Date; provided, however, that payment of Executive’s accounts under the DCP shall be made generally in accordance with the DCP. Payments relating to the preceding subsections (i) through (iv) shall commence (or be paid in full, with respect to lump sum payments) on the first regular payroll period that follows the expiration of the release revocation period (the “Payment Commencement Date”); provided, that any payments relating the preceding subsection (i) for payroll periods occurring after the Transition Date and prior to the Payment Commencement Date shall be made on the Payment Commencement Date, without interest. The payments under this Section 2 are subject to applicable withholding and taxes.

(b)Termination for Cause. Notwithstanding anything to the contrary herein, if the Executive is terminated by the Company for Cause at any time prior to the Transition Date, then the Executive shall not be entitled to receive any further payments or

2

benefits under this Agreement and the Company shall have no further obligations to the Executive under this Agreement, except to the extent required by law.

3.Consulting Period.

(a)Consulting Services. Commencing on the Transition Date, the Executive agrees to provide reasonable consulting services to the Company through December 31, 2024 (such period, the “Consulting Period”), subject to the terms and conditions of this Agreement. Said services shall be during ordinary business hours, shall not require travel or weekend work and time spent shall be as mutually and reasonably agreed by the parties. Executive shall have no liability to Company whatsoever for any liabilities, damages, costs or expenses incurred by Company with respect to any consulting services so performed by Executive except for damages caused by her intentional misconduct or gross negligence.

(b)Consulting Services Compensation. Subject to the Executive’s continuing availability to provide consulting services in accordance with the terms hereof, during the Consulting Period the Executive shall be considered a “Service Provider” to the Company as defined in the applicable equity incentive plans and award agreements. To the extent applicable and notwithstanding anything to the contrary in any applicable equity incentive plans and award agreements, the Executive’s outstanding stock options, restricted stock units and performance stock units will remain outstanding and will continue to vest during the Consulting Period in accordance with and subject to the terms and conditions set forth in the applicable equity incentive plans and award agreements.

(b)The Executive agrees not to make any adverse or disparaging comments (oral or written, including, without limitation, via any form of electronic media) about the Company, its affiliates, or any of their respective officers, directors, managers or employees which may tend to impugn or injure their reputation, goodwill and relationships with their past, present and future customers, employees, vendors, investors or with the business community generally. The Company agrees that its executive officers and directors shall be directed not to make any disparaging comments (oral or written, including, without limitation, via any form of electronic media) about the Executive. Nothing in this Section 4 is intended to prohibit, limit or

3

prevent the Executive or the Company’s officers or directors from providing truthful testimony in a court of law, to a regulatory or law enforcement agency or pursuant to a properly issued subpoena, and such testimony will not be deemed to be a violation of this Section 4. Nothing herein shall prevent Executive from discussing or disclosing information regarding unlawful acts in the workplace, such as harassment, discrimination or any other conduct that Executive has reason to believe is unlawful.

(c)Notwithstanding anything herein or in the Restrictive Covenants, pursuant to the federal Defend Trade Secrets Act of 2016, an individual shall not be held criminally or civilly liable under any federal or state trade secret law for the disclosure of a trade secret that: (A) is made (1) in confidence to a federal, state or local government official, either directly or indirectly, or to an attorney and (2) solely for the purpose of reporting or investigating a suspected violation of law; (B) is made to the individual’s attorney in relation to a lawsuit for retaliation against the individual for reporting a suspected violation of law; or (C) is made in a complaint or other document filed in a lawsuit or proceeding, if such filing is made under seal.

5.Other Severance Pay or Benefits. The Severance Amount provided for in Section 2 shall be in lieu of any other severance or termination pay to which the Executive may be entitled under any Company severance or termination plan, program or practice (whether written or unwritten) or agreement. Except as otherwise provided herein, the Executive’s entitlement to any other compensation or benefits shall be determined in accordance with the terms and conditions of the Company’s employee benefit plans (other than severance or termination plans, programs, practices or agreements) and other applicable programs, policies and practices then in effect. Company agrees that it will not oppose any application for unemployment benefits submitted by the Executive.

6.Successors: Binding Agreement.

(a)This Agreement shall be binding upon and shall inure to the benefit of the Company, and its successors and assigns, and the Company shall require any successors and assigns to expressly assume and agree to perform this Agreement in the same manner and to the same extent that the Company would be required to perform it if no such succession or assignment had taken place.

(b)Neither this Agreement nor any right or interest hereunder shall be assignable or transferable by the Executive, her beneficiaries or legal representatives, except by will or by the laws of descent and distribution. This Agreement shall inure to the benefit of and be enforceable by the Executive’s personal representative.

7.Tax Treatment; Tax Withholding. The Company and the Executive hereby acknowledge and agree that the compensation provided for in Section 1 and the Severance Amount provided for in Section 2 shall be treated and reported by the Company and the Executive as additional compensation for services rendered and as ordinary income. The Executive also acknowledges and agrees that the Company may withhold from any compensation or other benefits to which the Executive is entitled hereunder such amounts as may be required to satisfy all federal, state and local withholding and employment tax obligations.

(c)Entire Agreement; Amendment. The recitals hereto are hereby incorporated herein by this reference. This Agreement, together with the exhibits hereto, constitute the entire agreement between the parties hereto with regard to the subject matter hereof and thereof, superseding all prior understandings and agreements, whether written or oral, including, without limitation, the Severance Agreement; provided, however, that any indemnification agreement and any outstanding vested equity award agreements (including, without limitation, any outstanding vested option agreement, restricted stock unit agreement, performance stock unit agreement, market stock unit agreement or other equity instrument by and between the Company and the Executive), and the Restrictive Covenants shall remain in full force and effect in accordance with the terms and conditions herein and therein.

5

may not be changed orally, but only by an agreement in writing signed by the party against whom enforcement of any such change is sought.

(d)409A Compliance. Notwithstanding any other provision herein to the contrary, the Company shall make the payments required hereunder in compliance with the requirements of Section 409A and any interpretative guidance issued thereunder. The Company may, in its sole and absolute discretion, delay payments hereunder or make such other modifications with respect to the timing of payments as it deems necessary to comply with Section 409A. Notwithstanding any provision herein to the contrary, in the event any payment or benefit hereunder is determined to constitute non-qualified deferred compensation subject to Section 409A, then to the extent necessary to comply with Section 409A, such payment or benefits shall not be made, provided or commenced until six (6) months after the Executive’s “separation from service” as such phrase is defined for the purposes of Section 409A. For purposes of Section 409A, each right to receive a payment hereunder shall be treated as a right to receive a series of separate payments and, accordingly, any installment payment shall at all times be considered a separate and distinct payment. For the avoidance of doubt, the Transition Date shall be the date of the Executive’s “separation from service” for purposes of Section 409A.

(f)Effect of Headings. The titles of section headings herein contained have been provided solely for convenience of reference and in no way define, limit or describe the scope or substance of any provision of this Agreement.

(g)Severability. The provisions of this Agreement are severable, and the invalidity of any provision shall not affect the validity of any other provision. In the event that any court of competent jurisdiction shall determine that any provision of this Agreement or the application thereof is unenforceable because of the duration or scope thereof, the parties hereto agree that said court in making such determination shall have the power to reduce the duration and scope of such provision to the extent necessary to make it enforceable, and that the Agreement in its reduced form shall be valid and enforceable to the full extent permitted by law.

(h)Governing Law/Jurisdiction. This Agreement shall be binding upon the Executive and shall inure to the benefit of the Company and its successors and interest and assigns, and shall be construed in accordance with and governed by the laws of the State of California without regard to conflicts of laws. The parties hereto intend and hereby confer jurisdiction to enforce the covenants contained herein upon the state and federal courts sitting in the State of California. In the event that such courts shall hold any such covenant wholly unenforceable by reason of the breadth of scope or otherwise, it is the intention of the parties hereto that such determination not bar or in any way affect the Company’s right to the relief

6

provided above in the courts of any other states within the geographical scope of such other covenants having appropriate personal and subject matter jurisdiction over the parties, as to breaches of such covenants in such other respective jurisdictions, the above covenants as they relate to each state being, for this purpose, severable into diverse and independent covenants.

(i)Counterparts. This Agreement may be executed in multiple original or facsimile counterparts (including *.pdf and the like), each of which shall be deemed an original, but all of which together shall constitute one and the same instrument.

Exhibit 10.2

SEVERANCE AND

CHANGE OF CONTROL AGREEMENT

    CHANGE OF CONTROL AGREEMENT by and between HOLOGIC, INC., a Delaware corporation (the "Company"), and Peter Dunne (the "Executive"), dated as of January 9, 2024.

    WHEREAS, the Executive serves as a senior executive of the Company;

WHEREAS, the Board of Directors of the Company (the "Board"), has determined that it is in the best interests of the Company and its shareholders to assure that the Company will have the continued dedication of the Executive, notwithstanding the possibility, threat, or occurrence of a Change of Control (as defined below) of the Company. The Board believes it is imperative to diminish the inevitable distraction of the Executive by virtue of the personal uncertainties and risks created by a pending or threatened Change of Control and to encourage the Executive's full attention and dedication to the Company currently and in the event of any threatened or pending Change of Control, and to provide the Executive with compensation and benefits arrangements upon a Change of Control which ensure that the compensation and benefits expectations of the Executive will be satisfied and which are competitive with those of other corporations;

WHEREAS, in recognition of the Executive’s role, the Company and Executive desire to enter into this Severance and Change of Control Agreement, which is consistent with the change of control and severance protection provided to the Company’s most senior officers (the “Agreement”); and

WHEREAS, this Agreement shall supersede and replace the Executive’s existing Change in Control Severance Plan for Vice Presidents, and Severance Plan for Vice Presidents.

    NOW, THEREFORE, in consideration of the mutual covenants and agreements hereinafter set forth, the parties hereto, each intending to be legally bound, do hereby agree as follows:

1.    Certain Definitions.

(a)    The "Effective Date" shall be the first date during the "Change of Control Period" (as defined in Section 1(b)) on which a Change of Control occurs. Anything in this Agreement to the contrary notwithstanding, if the Executive's employment with the Company is terminated or the Executive ceases to be an officer of the Company prior to the date on which a Change of Control occurs, and it is reasonably demonstrated that such termination of employment (1) was at the request of a third party who has taken steps reasonably calculated to effect the Change of Control or (2) otherwise arose in connection with or in anticipation of the Change of Control, then for all purposes of this Agreement the "Effective Date" shall mean the date immediately prior to the date of such termination of employment. If prior to the Effective Date, the Executive’s employment with the Company terminates, then the Executive shall have no further rights under this Agreement, except with respect to benefits under Section 6(e), if applicable, or unless such termination of Employment was in anticipation of the Change of

Control in which case the termination shall be deemed to have occurred after the consummation of the Change of Control.

    (b)    The "Change of Control Period" is the period commencing on the date hereof and ending on December 31, 2026; provided, that commencing on December 31, 2025 and each December 31 thereafter (each such date to be referred to as the “Renewal Date”), the term of this Agreement shall automatically be extended, without any further action by the Company or the Executive, so as to terminate three years from such Renewal Date; provided, however that if the Company shall give notice in writing to the Executive at least thirty (30) days prior to a Renewal Date (the “Pending Renewal Date”), stating that the Change of Control Period shall not be extended, then the Change of Control Period shall expire two years from the Pending Renewal Date.

2.    Change of Control. For the purpose of this Agreement, a "Change of Control" shall mean:

(a)    The acquisition by any individual, entity or group (within the meaning of Section 13(d)(3) or 14(d)(2) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”)) of beneficial ownership (within the meaning of Rule 13d-3 promulgated under the Exchange Act) of 30% or more of the Voting Stock of the Company; provided, however, that any acquisition by the Company or its subsidiaries, or any employee benefit plan (or related trust) of the Company or its subsidiaries of 30% or more of Voting Stock shall not constitute a Change in Control; and provided, further, that any acquisition by a corporation with respect to which, following such acquisition, more than 50% of the Voting Stock of such corporation, is then beneficially owned, directly or indirectly, by all or substantially all of the individuals and entities who were the beneficial owners of the Voting Stock immediately prior to such acquisition in substantially the same proportion as their ownership, immediately prior to such acquisition, of the Voting Stock, shall not constitute a Change in Control; or

(b)    Any transaction which results in the Continuing Directors (as defined in the Certificate of Incorporation of the Company) constituting less than a majority of the Board of Directors of the Company (the “Board”); or

(c)    The consummation of (i) a Merger with respect to which all or substantially all of the individuals and entities who were the beneficial owners of the Voting Stock immediately prior to such Merger do not, following such Merger, beneficially own, directly or indirectly, more than 50% of the Voting Stock of the corporation resulting from the Merger (the “Resulting Corporation”) as a result of the individuals’ and entities’ shareholdings in the Company immediately prior to the consummation of the Merger, (ii) a complete liquidation or dissolution of the Company or (iii) the sale or other disposition of all or substantially all (as defined under Delaware General Corporation Law) of the assets of the Company excluding a sale or other disposition of assets to a subsidiary of the Company. For purposes of this Agreement “Merger”means a reorganization, merger or consolidation involving the Company, including without limitation as a parent of a direct or indirect subsidiary of the Company effecting such transaction

    -2-

    Anything in this Agreement to the contrary notwithstanding, if an event that would, but for this paragraph, constitute a Change of Control results from or arises out of a purchase or other acquisition of the Company, directly or indirectly, by a corporation or other entity in which the Executive has a greater than ten percent (10%) direct or indirect equity interest, such event shall not constitute a Change of Control.

3.    Employment Period. Subject to the terms and conditions hereof, the Company hereby agrees to continue the Executive in its employ, and the Executive hereby agrees to remain in the employ of the Company, for the period commencing on the Effective Date and ending on the last day of the thirty-sixth month following the month in which the Effective Date occurs (the "Employment Period").

4.    Terms of Employment.

(a)    Position and Duties.

(i)    During the Employment Period, (A) the Executive's position (including status, offices, titles and reporting requirements), authority, duties and responsibilities shall be at least commensurate in all material respects with the most significant of those held, exercised and assigned at any time during the 90-day period immediately preceding the Effective Date and (B) the Executive's services shall be performed at the location where the Executive was employed immediately preceding the Effective Date or any office or location less than 35 miles from such location.

(ii)    During the Employment Period, and excluding any periods of vacation and sick leave to which the Executive is entitled, the Executive agrees to devote her full business time to the business and affairs of the Company and, to the extent necessary to discharge the responsibilities assigned to the Executive hereunder, to use the Executive's reasonable best efforts to perform faithfully and efficiently such responsibilities. During the Employment Period it shall not be a violation of this Agreement for the Executive to (A) serve on corporate, civic or charitable boards or committees, (B) deliver lectures, fulfill speaking engagements or teach at educational institutions and (C) manage personal investments, so long as such activities do not significantly interfere with the performance of the Executive's responsibilities as an employee of the Company in accordance with this Agreement. It is expressly understood and agreed that to the extent that any such activities have been conducted by the Executive prior to the Effective Date, the continued conduct of such activities (or the conduct of activities similar in nature and scope thereto) subsequent to the Effective Date.

    (b)    Compensation.

(i)    Base Salary. During the Employment Period, the Executive shall receive an annual base salary ("Annual Base Salary"), which shall be paid monthly, having a value at least equal to twelve times the highest monthly base salary paid or payable to the Executive by the Company and its affiliated companies in respect of the twelve-month

    -3-

period immediately preceding the month in which the Effective Date occurs. During the Employment Period, the Annual Base Salary shall be reviewed at least annually and shall be increased at any time and from time to time as shall be substantially consistent with increases in base salary awarded in the ordinary course of business to other peer executives of the Company and its affiliated companies. Any increase in Annual Base Salary shall not serve to limit or reduce any other obligation to the Executive under this Agreement. Annual Base Salary shall not be reduced after any such increase and the term Annual Base Salary as utilized in this Agreement shall refer to Annual Base Salary as so increased. As used in this Agreement, the term "affiliated companies" includes any company controlled by, controlling or under common control with the Company.

(ii)    Annual Bonus. In addition to Annual Base Salary, the Executive shall be awarded, for each fiscal year during the Employment Period, an annual cash bonus (the "Annual Bonus"; which shall include, without limitation, any other annual cash bonus plan or program provided to Executive such as the Short Term Incentive Plan or any other similar plan, but shall not include any cash sign-on, relocation, retention or other special bonus or payments. ) in cash at least equal to the greater of (a) the average (annualized for any fiscal year consisting of less than twelve full months or with respect to which the Executive has been employed by the Company for less than twelve full months) bonus (the "Average Annual Bonus") paid or that has been earned and accrued, but unpaid to the Executive by the Company and its affiliated companies in respect of the three fiscal years immediately preceding the fiscal year in which the Effective Date occurs, (b) the Annual Bonus paid for the fiscal year immediately preceding the Effective Date, or (c) the target bonus associated with the Company achieving its 100 percent target payout level as determined in accordance with the terms of the Company’s bonus plans for senior executives for the fiscal year immediately preceding the Effective Date (the “Target Bonus”; the greater of clauses (a), (b) or (c) to be referred to as the “Highest Annual Bonus”); for the avoidance of doubt, the determination of bonus under clause (c) above shall not be reduced for the application of the Compensation Committee’s discretion to reduce such bonus or bonus funding, or increased to reflect additional amounts that may be paid or payable if the Company exceeds target. Each such Annual Bonus shall be paid no later than the 15th day of the third month of the fiscal year next following the fiscal year for which the Annual Bonus is awarded, unless the Executive shall elect to defer the receipt of such Annual Bonus pursuant to any nonqualified plan of the Company. Notwithstanding anything herein to the contrary, any portion of Annual Base Salary or Annual Bonus electively deferred by the Executive pursuant to a qualified or a non-qualified plan including, but not limited to, the Hologic, Inc. Deferred Compensation Plan or any successor thereto (“DCP”) shall be included in determining the Annual Base Salary, Annual Bonus and the Average Annual Bonus. If the fiscal year of any successor to this Agreement, as described by Section 11(c) herein, is different than the Company’s fiscal year at the time of the Change of Control, then the Executive shall be paid (i) the Annual Bonus that would have been paid upon the end of Company’s fiscal year ending after the Change of Control, and (ii) a pro-rata Annual Bonus for any months of service performed following the end of the Company’s fiscal year, but prior to the first day of the successor’s fiscal year immediately following the Change of Control. The Annual Bonuses thereafter shall be based on the successor’s first full fiscal year beginning after the Change of Control and successive fiscal years thereafter. “Pro Rata Bonus" shall mean an amount equal to the Bonus Amount (average of the Annual Bonuses

    -4-

paid or that has been earned and accrued, but unpaid during the three full fiscal years ended prior to the Date of Termination) multiplied by a fraction the numerator of which is the number of months worked in the fiscal year through the Date of Termination and the denominator of which is 12. Any partial months shall be rounded to the nearest whole number using normal mathematical convention.

(iii)    Incentive, Savings and Retirement Plans. In addition to Annual Base Salary and Annual Bonus payable as hereinabove provided, the Executive shall be entitled to participate during the Employment Period in all incentive, savings and retirement plans, practices, policies and programs applicable to other peer executives of the Company and its affiliated companies, but in no event shall such plans practices, policies and programs provide the Executive with incentive, savings and retirement benefits opportunities, in each case, less favorable, in the aggregate, than the most favorable of those provided by the Company and its affiliated companies for the Executive under such plans, practices, policies and programs as in effect at any time during the one-year immediately preceding the Effective Date, or, if more favorable to the Executive, those provided generally at any time after the Effective Date to other peer executives of the Company and its affiliated companies.

(iv)    Welfare Benefit Plans. During the Employment Period, the Executive and/or the Executive's family, as the case may be, shall be eligible for participation in and shall receive all benefits under welfare benefit plans, practices, policies and programs provided by the Company and its affiliated companies (including, without limitation, medical, prescription, dental, disability, salary continuance, employee life, group life, accidental death and travel accident insurance plans and programs) and applicable to other peer executives of the Company and its affiliated companies, but in no event shall such plans, practices, policies and programs provide benefits which are less favorable, in the aggregate, than the most favorable of such plans, practices, policies and programs in effect at any time during the one-year period immediately preceding the Effective Date, or, if more favorable to the Executive, those provided generally at any time after the Effective Date to other peer executives of the Company and its affiliated companies.

(v)    Expenses. During the Employment Period, the Executive shall be entitled to receive prompt reimbursement for all reasonable expenses incurred by the Executive upon submission of appropriate accountings in accordance with the most favorable policies, practices and procedures of the Company and its affiliated companies in effect at any time during the one-year period immediately preceding the Effective Date or, if more favorable to the Executive, as in effect at any time thereafter with respect to other peer executives of the Company and its affiliated companies.

(vi)    Fringe Benefits. During the Employment Period, the Executive shall be entitled to fringe benefits in accordance with the most favorable plans, practices, programs and policies of the Company and its affiliated companies in effect at any time during the one-year period immediately preceding the Effective Date or, if more

    -5-

favorable to the Executive, as in effect at any time thereafter with respect to other peer executives of the Company and its affiliated companies.

(vii)    Office and Support Staff. During the Employment Period, the Executive shall be entitled to an office or offices of a size and with furnishings and other appointments, and to exclusive personal secretarial and other assistance, at least equal to the most favorable of the foregoing provided to the Executive by the Company and its affiliated companies at any time during the one-year period immediately preceding the Effective Date or, if more favorable to the Executive, as provided at any time thereafter with respect to other peer executives of the Company and its affiliated companies.

(viii)    Vacation. During the Employment Period, the Executive shall be entitled to paid vacation of at least five (5) weeks and in accordance with the most favorable plans, policies, programs and practices of the Company and its affiliated companies as in effect at any time during the one-year period immediately preceding the Effective Date or, if more favorable to the Executive, as in effect at any time thereafter with respect to other peer incentives of the Company and its affiliated companies.

5.    Termination of Employment.

(a)    Death or Disability. The Executive's employment shall terminate automatically upon the Executive's death during the Employment Period. If the Company determines in good faith that the Disability of the Executive has occurred during the Employment Period (pursuant to the definition of "Disability" set forth below), it may give to the Executive written notice in accordance with Section 13(b) of this Agreement of its intention to terminate the Executive's employment. In such event, the Executive's employment with the Company shall terminate effective on the 30th day after receipt of such notice by the Executive (the "Disability Effective Date"), provided that, within the 30 days after such receipt, the Executive shall not have returned to full-time performance of the Executive's duties. For purposes of this Agreement, "Disability" means the absence of the Executive from the Executive's duties with the Company on a full-time basis for 180 consecutive business days as a result of incapacity due to mental or physical illness which is determined to be total and permanent by a physician selected by the Company or its insurers and acceptable to the Executive or the Executive's legal representative (such agreement as to acceptability not to be withheld unreasonably).

    (b)    Cause. The Company may terminate the Executive's employment during the Employment Period for "Cause". For purposes of this Agreement, "Cause" means (i) an act or acts of personal dishonesty taken by the Executive and intended to result in substantial personal enrichment of the Executive at the expense of the Company, (ii) repeated violations by the Executive of the Executive's obligations under Section 4(a) of this Agreement (other than as a result of incapacity due to physical or mental illness) which are demonstrably willful and deliberate on the Executive's part, which are committed in bad faith or without reasonable belief that such violations are in the best interests of the Company and which are not remedied in a reasonable period of time after receipt of written notice from the Company or (iii) the conviction of the Executive of a felony involving moral turpitude. The Company shall provide the

    -6-

Executive with 30 days written notice of any determination of Cause and provide the Executive, for a period of 30 days following such notice, with the opportunity to appear before the Board, with or without legal representation, to present arguments and evidence on her behalf and following such presentation to the Board, the Executive may only be terminated for Cause if the Board (excluding the Executive if she is a member of the Board), by unanimous consent reasonably determines in good faith that her actions did, in fact, constitute for Cause.

    (c)    Good Reason. The Executive's employment may be terminated during the Employment Period by the Executive for Good Reason. For purposes of this Agreement, "Good Reason" means:

(i)    A material diminution in the Executive’s base compensation;

(ii)    A material diminution in the Executive’s authority, duties and responsibilities as in effect immediately prior to the Change of Control or, if applicable, the Date of Termination;

(iii)    A material diminution in the authority, duties and responsibilities of the supervisor to whom the Executive is required to report as in effect immediately prior to the Change of Control or, if applicable, the Date of Termination;

(iv)    A material change in the geographic location in which Executive’s principal office was located immediately prior to the Change of Control or, if applicable, the Date of Termination;

(v)    A material diminution in the budget over which the Executive had authority immediately prior to the of the Change of Control or, if applicable, the Date of Termination;

(vi)    Any other action or inaction that constitutes a material breach by the Company of this Agreement or any other agreement under which the Executive provides services;

provided, however, that Good Reason shall not exist unless the Executive has given written notice to the Company within ninety (90) days of the initial existence of the Good Reason event or condition(s) giving specific details regarding the event or condition; and unless the Company has had at least thirty (30) days to cure such Good Reason event or condition after the delivery of such written notice and has failed to cure such event or condition within such thirty (30) day cure period.

    (d)    Notice of Termination. Any termination by the Company for Cause or by the Executive for Good Reason shall be communicated by Notice of Termination to the other party hereto given in accordance with Section 13(b) of this Agreement. For purposes of this Agreement, a "Notice of Termination" means a written notice which (i) indicates the specific termination provision in this Agreement relied upon, (ii) to the extent applicable, sets forth in reasonable detail the facts and circumstances claimed to provide a basis for termination of the

    -7-

Executive's employment under the provision so indicated and (iii) if the Date of Termination (as defined below) is other than the date of receipt of such notice, specifies the termination date (which date shall be not more than fifteen days after the giving of such notice). The failure by the Executive or the Company to set forth in the Notice of Termination any fact or circumstance which contributes to a showing of Good Reason or Cause shall not waive any right of the Executive or the Company hereunder or preclude the Executive or the Company from asserting such fact or circumstance in enforcing the Executive's or the Company’s rights hereunder.

    (e)    Date of Termination. "Date of Termination" means the date of receipt of the Notice of Termination or any later date (taking into account any applicable notice and cure period) specified therein, as the case may be; provided however, that (i) if the Executive's employment is terminated by the Company other than for Cause, death or Disability, the Date of Termination shall be the date on which the Company notifies the Executive of such termination, and (ii) if the Executive's employment is terminated by reason of death or Disability, the Date of Termination shall be the date of death of the Executive or the Disability Effective Date, as the case may be.

6.    Obligations of the Company upon Termination.

    (a)    Death. If the Executive's employment is terminated by reason of the Executive's death during the Employment Period, this Agreement shall terminate without further obligations to the Executive's legal representatives under this Agreement, other than for (i) payment of the sum of the following amounts: (A) the Executive's Annual Base Salary through the Date of Termination to the extent not theretofore paid, (B) the product of (I) the Highest Annual Bonus and (II) a fraction, the numerator of which is the number of days in the current fiscal year through the Date of Termination, and the denominator of which is 365, and (C) any accrued and unpaid Annual Bonus amounts, compensation or vacation pay, in each case, to the extent not yet paid by the Company (the amounts described in subparagraphs (A), (B) and (C) are hereafter referred to as "Accrued Obligations" and shall be paid to the Executive’s estate or beneficiary, as applicable, in a lump sum in cash within 30 days of the Date of Termination), (ii) any other benefits or compensation payable under any employee benefit plan in accordance with the applicable plans’ terms, including, without limitation, any non-qualified plan or DCP; (iii) for the remainder of the Employment Period, or such longer period as any plan, program, practice or policy may provide, the Company shall continue benefits to the Executive and/or the Executive's family at least equal to those which would have been provided in accordance with the applicable plans, programs, practices and policies described in Section 4(b)(v) and (vi) of this Agreement as if the Executive's employment had not been terminated in accordance with the most favorable plans, practices, programs or policies of the Company and its affiliated companies as in effect and applicable generally to other peer executives and their families during the one year period immediately preceding the Effective Date or, if more favorable to the Executive, as in effect at any time thereafter with respect to other peer executives of the Company and its affiliated companies and their families (such continuation of such benefits for the applicable period herein set forth and such transfer of the Individual Policy shall be hereinafter referred to as “Welfare Benefit Continuation”; for purposes of determining eligibility of the Executive for retiree benefits pursuant to such plans, practices, programs and policies, the Executive shall be

    -8-

considered to have remained employed until the end of the Employment Period and to have retired on the last day of such period), and (iv) payment to the Executive’s estate or beneficiary, as applicable, in a lump sum in cash within 30 days of the Date of Termination of an amount equal to the sum of the Executive’s Annual Base Salary and the Highest Annual Bonus. Subject to the provisions of Section 9 hereof, but, otherwise, anything herein to the contrary notwithstanding, the Executive's family shall be entitled to receive benefits at least equal to the most favorable benefits provided by the Company and any of its affiliated companies to surviving families of peer executives of the Company and such affiliated companies under such plans, programs, practices and policies relating to family death benefits, if any, as in effect with respect to other peer executives and their families at any time during the one year period immediately preceding the Effective Date or, if more favorable to the Executive and/or the Executive's family, as in effect on the date of the Executive's death with respect to other peer executives of the Company and its affiliated companies and their families.

    (b)    Disability. If the Executive's employment is terminated by reason of the Executive's Disability during the Employment Period, this Agreement shall terminate without further obligations to the Executive, other than for (i) payment of the Accrued Obligations (which shall be paid in a lump sum in cash within 30 days of the Date of Termination), (ii) the timely payment and provision of the Welfare Benefit Continuation, and (iii) payment to the Executive in a lump sum in cash within 30 days of the Date of Termination of an amount equal to the sum of the Executive’s Annual Base Salary and the Highest Annual Bonus. Subject to the provisions of Section 9 hereof, but, otherwise, anything herein to the contrary notwithstanding, the Executive shall be entitled after the Disability Effective Date to receive disability and other benefits at least equal to the most favorable of those provided by the Company and its affiliated companies to disabled executives and/or their families in accordance with such plans, programs, practices and policies relating to disability, if any, as in effect with respect to other peer executives and their families at any time during the one year period immediately preceding the Effective Date or, if more favorable to the Executive and/or the Executive's family, as in effect at any time thereafter with respect to other peer executives of the Company and its affiliated companies and their families.

    (c)    Cause, Other than for Good Reason. If the Executive's employment shall be terminated by the Company for Cause or by the Executive other than for Good Reason (and other than by reason of her death or disability) during the Employment Period, this Agreement shall terminate without further obligations to the Executive other than the obligation to pay to the Executive Annual Base Salary through the Date of Termination. In such case, such amounts shall be paid to the Executive in a lump sum in cash within 30 days of the Date of Termination. The Executive shall, in such event, also be entitled to any benefits required by law that are not otherwise provided by this Agreement.

(d)    Termination Following a Change of Control by the Company without Cause or by the Executive for Good Reason. If during the Employment Period the Executive is terminated by the Company without Cause or she resigns for Good Reason, then the Company shall pay the Executive the following:

    -9-

(i)    the Company shall pay to the Executive in a lump sum in cash within 30 days after the Date of Termination all Accrued Obligations; and

(ii)    the Company shall pay to the Executive a lump sum amount in cash within 30 days after the Date of Termination equal to the (such amount shall be hereinafter referred to as the “Change of Control Payment”) to the product of (X) two point ninety nine (2.99) multiplied by the sum of (i) (Y) the Annual Base Salary for the fiscal year immediately preceding the Date of Termination and (ii) Highest Annual Bonus; and

(iii)    notwithstanding any other provisions to the contrary contained herein or in any option agreement, restricted stock agreement, performance stock unit or other equity compensation agreement, between the Company and the Executive, or any stock option, restricted stock or other equity compensation plans sponsored by the Company, unless such agreement or plan expressly references and supersedes this Agreement, then all such unvested equity awards which Executive holds as of the Effective Date shall be immediately and automatically exercisable and/or vested, and the Executive shall have the right to exercise any such equity awards (to the extent applicable) for the shorter of one year after the Date of Termination or the remaining term of the applicable equity award.

(e)    Termination by the Company Without Cause or by Executive for Good Reason. If the Executive's employment with the Company shall be terminated by the Company without Cause or by the Executive for Good Reason (as defined in Section 5(c) without regard to whether a Change of Control has occurred) at any time prior to the Effective Date, then the Executive shall be entitled to each and all of the following:

(i)the Company shall pay the Executive all Accrued Obligations;

(ii)the Company shall continue to pay the Executive her Base Salary and an amount equal to the Average Annual Bonus divided by the number of payroll periods during the one year severance period for the period of one (1) year from the Date of Termination in accordance with its normal payroll practices and subject to applicable tax withholding; and

(iii)provide the Executive and her family with the Welfare Benefit Continuation for a period of one (1) year from the Date of Termination.

(f)    Mitigation. The Executive shall not be required to mitigate the amount of any payment provided for in this Agreement by seeking other employment or otherwise and no such payment shall be offset or reduced by the amount of any compensation or benefits provided to the Executive in any subsequent employment.

(g)    Other Severance Benefits. The severance pay and benefits provided for in Section 6(e) shall be in lieu of any other severance or termination pay to which the Executive may be entitled under any Company severance or termination plan, program, practice or arrangement.

    -10-

The Executive's entitlement to any other compensation or benefits shall be determined in accordance with the Company's employee benefit plans and other applicable programs, policies and practices then in effect.

7.    Non-exclusivity of Rights. Except as provided in Section 6, nothing in this Agreement shall prevent or limit the Executive's continuing or future participation in any benefit, bonus, incentive or other plans, programs, policies or practices, provided by the Company or any of its affiliated companies and for which the Executive may qualify, nor shall anything herein limit or otherwise affect such rights as the Executive may have under any other agreements with the Company or any of its affiliated companies. Amounts which are vested benefits or which the Executive is otherwise entitled to receive under any plan, policy, practice or program of the Company or any of its affiliated companies at or subsequent to the Date of Termination shall be payable in accordance with such plan, policy, practice or program except as explicitly modified by this Agreement.

8.    Full Settlement.

(a)    The Company's obligation to make the payments provided for in this Agreement and otherwise to perform its obligations hereunder shall not be affected by any set-off, counterclaim, recoupment, defense or other claim, right or action which the Company may have against the Executive or others. In no event shall the Executive be obligated to seek other employment or take any other action by way of mitigation of the amounts payable to the Executive under any of the provisions of this Agreement and such amounts shall not be reduced whether or not the Executive obtains other employment.

(b)    Prior to the occurrence of a Change of Control, the Company agrees to reimburse the Executive for all legal fees and expenses which the Executive may reasonably incur as a result of any contest by the Company, the Executive or others of the validity or enforceability of, or liability under, any provision of this Agreement or any guarantee of performance thereof, if the Executive prevails in such contest. Following a Change of Control, the Company agrees to pay promptly as incurred, to the full extent permitted by law, all legal fees and expenses which the Executive may reasonably incur as a result of any contest (regardless of the outcome thereof) by the Company, the Executive or others of the validity or enforceability of, or liability under, any provision of this Agreement or any guarantee of performance thereof.

    (c)    If there shall be any dispute between the Company and the Executive (i) in the event of any termination of the Executive’s employment by the Company, whether such termination was for Cause, or (ii) in the event of any termination of employment by the Executive, whether Good Reason existed, then, unless and until there is a final, nonappealable judgment by a court of competent jurisdiction declaring that such termination was for Cause or that the determination by the Executive of the existence of Good Reason was not made in good faith, the Company shall pay all amounts, and provide all benefits, to the Executive and/or the Executive’s family or other beneficiaries, as the case may be, that the Company would be required to pay or provide pursuant to Section 6(d) as though such termination were by the Company without Cause, or by the Executive with Good Reason; provided, however, that the

    -11-

Company shall not be required to pay any disputed amount pursuant to this paragraph except upon receipt of an undertaking by or on behalf of the Executive to repay all such amounts to which the Executive is ultimately adjudged by such court not to be entitled.

9.    280G Protection.

(a)    In the event that the Executive shall become entitled to payment and/or benefits provided by this Agreement or any other amounts in the “nature of compensation” (whether pursuant to the terms of this Agreement or any other plan, arrangement or agreement with the Company, any person whose actions result in a change of ownership or effective control covered by Section 280G(b)(2) of the Internal Revenue Code (the “Code”) or any person affiliated with the Company or such person) as a result of such change in ownership or effective control (collectively the “Company Payments”), and such Company Payments will be subject to the tax (the “Excise Tax”) imposed by Section 4999 of the Code (and any similar tax that may hereafter be imposed by any taxing authority) the Company shall pay to the Executive the greater of the following, whichever gives the Executive the highest net after-tax amount (after taking into account federal, state, local and social security taxes at the maximum marginal rates) (x) the Company Payments or (y) one dollar less than the amount of the Company Payments that would subject the Executive to the Excise Tax. In the event that the Company Payments are required to be reduced pursuant to the foregoing sentence, then the Company Payments shall be reduced as mutually agreed between the Company and the Executive or, in the event the parties cannot agree, in the following order (1) any lump sum severance based on Base Salary or Annual Bonus, (2) any other cash amounts payable to the Executive, (3) any benefits valued as parachute payments; and (4) acceleration of vesting of any equity.

(b)    For purposes of determining whether any of the Company Payments will be subject to the Excise Tax and the amount of such Excise Tax, (x) the Company Payments shall be treated as “parachute payments” within the meaning of Section 280G(b)(2) of the Code, and all “parachute payments” in excess of the “base amount” (as defined under Code Section 280G(b)(3) of the Code) shall be treated as subject to the Excise Tax, unless and except to the extent that, in the opinion of the Company’s independent certified public accountants appointed prior to any change in ownership (as defined under Section 280G(b)(2) of the Code) or tax counsel selected by such accountants or the Company (the “Accountants”) such Company Payments (in whole or in part) either expressly do not constitute “parachute payments,” represent reasonable compensation for services actually rendered within the meaning of Section 280G(b)(4) of the Code in excess of the “base amount” or are otherwise not subject to the Excise Tax, and (y) the value of any non-cash benefits or any deferred payment or benefit shall be determined by the Accountants. All determinations hereunder shall be made by the Accountants which shall provide detailed supporting calculations both to the Company and the Executive at such time as it is requested by the Company or the Executive. If the Accountants determine that payments under this Agreement must be reduced pursuant to this paragraph, they shall furnish the Executive with a written opinion to such effect. The determination of the Accountants shall be final and binding upon the Company and the Executive.

    -12-

(c)    In the event of any controversy with the Internal Revenue Service (or other taxing authority) with regard to the Excise Tax, the Executive shall permit the Company to control issues related to the Excise Tax (at its expense), provided that such issues do not potentially materially adversely affect the Executive, but the Executive shall control any other issues. In the event the issues are interrelated, the Executive and the Company shall in good faith cooperate so as not to jeopardize resolution of either issue, but if the parties cannot agree the Executive shall make the final determination with regard to the issues. In the event of any conference with any taxing authority regarding the Excise Tax or associated income taxes, the Executive shall permit the representative of the Company to accompany the Executive, and the Executive and the Executive’s representative shall cooperate with the Company and its representative.

10.    Confidential Information. The Executive shall hold in a fiduciary capacity for the benefit of the Company all secret or confidential information, knowledge or data relating to the Company or any of its affiliated companies, and their respective businesses, which shall have been obtained by the Executive during the Executive's employment by the Company or any of its affiliated companies and which shall not be or become public knowledge (other than by acts by the Executive or representatives of the Executive in violation of this Agreement). After termination of the Executive's employment with the Company, the Executive shall not, without the prior written consent of the Company or as may otherwise be required by law or legal process, communicate or divulge any such information, knowledge or data to anyone other than the Company and those designated by it. In no event shall an asserted violation of the provisions of this Section 10 constitute a basis for deferring or withholding any amounts otherwise payable to the Executive under this Agreement.

11.    Successors.

(a)    This Agreement is personal to the Executive and without the prior written consent of the Company shall not be assignable by the Executive otherwise than by will or the laws of descent and distribution. This Agreement shall inure to the benefit of and be enforceable by the Executive's legal representatives.

    (b)    This Agreement shall inure to the benefit of and be binding upon the Company and its successors and assigns.

    (c)    The Company will require any successor (whether direct or indirect, by purchase, merger, consolidation or otherwise) to all or substantially all of the business and/or assets of the Company to assume expressly and agree to perform this Agreement in the same manner and to the same extent that the Company would be required to perform it if no such succession had taken place. The Company shall provide written evidence to the Executive to document compliance with the foregoing sentence within ten (10) business days of the Effective Date. As used in this Agreement, "Company" shall mean the Company as hereinbefore defined and any successor to its business and/or assets as aforesaid which assumes and agrees to perform this Agreement by operation of law, or otherwise. In addition, the Executive shall be entitled, upon exercise of any outstanding stock options or stock appreciation rights of the Company, to receive in lieu of shares of the Company’s stock, shares of such stock or other securities of such

    -13-

successor as the holders of shares of the Company’s stock received pursuant to the terms of the merger, consolidation or sale.

12.    Compliance With Section 409A of the Internal Revenue Code. To the extent applicable, it is intended that this Agreement comply with the provisions of Section 409A of the Code (hereinafter referred to as “Section 409A”). This Agreement shall be administered in a manner consistent with its intent, and any provision that would cause the Agreement to fail to satisfy Section 409A shall have no force and effect until amended to comply with Section 409A. Notwithstanding any provision of this Agreement to the contrary, in the event any payment or benefit hereunder is determined to constitute non-qualified deferred compensation subject to Section 409A, then to the extent necessary to comply with Section 409A, such payment or benefits shall not be made, provided or commenced until six (6) months after the Executive’s “separation from service” as such phrase is defined for the purposes of Section 409A.

13.Release. The Executive agrees that, with the exception of the Accrued Obligations due to her in accordance with the terms hereunder, that the payment of any severance under this Agreement to the Executive by the Company, is subject to and conditioned on Executive executing a general release of the Company in a form and scope determined by the Company in its sole discretion (the “Release Agreement”), without Executive revoking such Release Agreement within fifty-two (52) days of the Date of Termination (the “Consideration Period”) and provided that (a) if the Date of Termination occurs in one calendar year and the Consideration Period (including the payment date) expires during the following calendar year, then notwithstanding anything herein to the contrary, the payments of severance under Section 6(e) will be paid by the Company to the Executive in the second calendar year; (b) the Executive continues to comply with the provisions of the Non-Competition Agreement; and (c) prior to the expiration of the Consideration Period (i) Executive provides satisfactory evidence to the Company that she has returned all Company property, confidential information and documentation to the Company, and (ii) provides the Company with a signed written resignation of Executive’s status as an officer of the Company or any of its affiliates, if applicable.

14.    Miscellaneous.

    (f)    This Agreement contains the entire understanding of the Company and the Executive with respect to the rights and other benefits that the Executive shall be entitled during the Employment Period, and in connection therewith shall supersede all prior oral and written communications with the Executive with respect thereto; provided, however, that the Offer Letter, and Employee Intellectual Property Rights and Non-Competition Agreement, option or other equity agreements or other employment agreement by and between the Company and Executive shall remain in full force and effect and if the Company’s separation policy would provide greater benefits to the Executive than this Agreement, then the Executive may elect to receive benefits under the Company’s separation policy in lieu of the benefits provided hereunder.

Exhibit 10.3

SEVERANCE AND

CHANGE OF CONTROL AGREEMENT

    CHANGE OF CONTROL AGREEMENT by and between HOLOGIC, INC., a Delaware corporation (the "Company"), and Brandon Schnittker (the "Executive"), dated as of January 18, 2024.

    WHEREAS, the Executive serves as a senior executive of the Company;

WHEREAS, the Board of Directors of the Company (the "Board"), has determined that it is in the best interests of the Company and its shareholders to assure that the Company will have the continued dedication of the Executive, notwithstanding the possibility, threat, or occurrence of a Change of Control (as defined below) of the Company. The Board believes it is imperative to diminish the inevitable distraction of the Executive by virtue of the personal uncertainties and risks created by a pending or threatened Change of Control and to encourage the Executive's full attention and dedication to the Company currently and in the event of any threatened or pending Change of Control, and to provide the Executive with compensation and benefits arrangements upon a Change of Control which ensure that the compensation and benefits expectations of the Executive will be satisfied and which are competitive with those of other corporations;

WHEREAS, in recognition of the Executive’s role, the Company and Executive desire to enter into this Severance and Change of Control Agreement, which is consistent with the change of control and severance protection provided to the Company’s most senior officers (the “Agreement”); and

WHEREAS, this Agreement shall supersede and replace the Executive’s existing Change in Control Severance Plan for Vice Presidents, and Severance Plan for Vice Presidents.

    NOW, THEREFORE, in consideration of the mutual covenants and agreements hereinafter set forth, the parties hereto, each intending to be legally bound, do hereby agree as follows:

1.    Certain Definitions.

(a)    The "Effective Date" shall be the first date during the "Change of Control Period" (as defined in Section 1(b)) on which a Change of Control occurs. Anything in this Agreement to the contrary notwithstanding, if the Executive's employment with the Company is terminated or the Executive ceases to be an officer of the Company prior to the date on which a Change of Control occurs, and it is reasonably demonstrated that such termination of employment (1) was at the request of a third party who has taken steps reasonably calculated to effect the Change of Control or (2) otherwise arose in connection with or in anticipation of the Change of Control, then for all purposes of this Agreement the "Effective Date" shall mean the date immediately prior to the date of such termination of employment. If prior to the Effective Date, the Executive’s employment with the Company terminates, then the Executive shall have no further rights under this Agreement, except with respect to benefits under Section 6(e), if

applicable, or unless such termination of Employment was in anticipation of the Change of Control in which case the termination shall be deemed to have occurred after the consummation of the Change of Control.

    (b)    The "Change of Control Period" is the period commencing on the date hereof and ending on December 31, 2026; provided, that commencing on December 31, 2025 and each December 31 thereafter (each such date to be referred to as the “Renewal Date”), the term of this Agreement shall automatically be extended, without any further action by the Company or the Executive, so as to terminate three years from such Renewal Date; provided, however that if the Company shall give notice in writing to the Executive at least thirty (30) days prior to a Renewal Date (the “Pending Renewal Date”), stating that the Change of Control Period shall not be extended, then the Change of Control Period shall expire two years from the Pending Renewal Date.

2.    Change of Control. For the purpose of this Agreement, a "Change of Control" shall mean:

(a)    The acquisition by any individual, entity or group (within the meaning of Section 13(d)(3) or 14(d)(2) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”)) of beneficial ownership (within the meaning of Rule 13d-3 promulgated under the Exchange Act) of 30% or more of the Voting Stock of the Company; provided, however, that any acquisition by the Company or its subsidiaries, or any employee benefit plan (or related trust) of the Company or its subsidiaries of 30% or more of Voting Stock shall not constitute a Change in Control; and provided, further, that any acquisition by a corporation with respect to which, following such acquisition, more than 50% of the Voting Stock of such corporation, is then beneficially owned, directly or indirectly, by all or substantially all of the individuals and entities who were the beneficial owners of the Voting Stock immediately prior to such acquisition in substantially the same proportion as their ownership, immediately prior to such acquisition, of the Voting Stock, shall not constitute a Change in Control; or

(b)    Any transaction which results in the Continuing Directors (as defined in the Certificate of Incorporation of the Company) constituting less than a majority of the Board of Directors of the Company (the “Board”); or

(c)    The consummation of (i) a Merger with respect to which all or substantially all of the individuals and entities who were the beneficial owners of the Voting Stock immediately prior to such Merger do not, following such Merger, beneficially own, directly or indirectly, more than 50% of the Voting Stock of the corporation resulting from the Merger (the “Resulting Corporation”) as a result of the individuals’ and entities’ shareholdings in the Company immediately prior to the consummation of the Merger, (ii) a complete liquidation or dissolution of the Company or (iii) the sale or other disposition of all or substantially all (as defined under Delaware General Corporation Law) of the assets of the Company excluding a sale or other disposition of assets to a subsidiary of the Company. For purposes of this Agreement “Merger”means a reorganization, merger or consolidation involving the Company, including without limitation as a parent of a direct or indirect subsidiary of the Company effecting such transaction

    -2-

    Anything in this Agreement to the contrary notwithstanding, if an event that would, but for this paragraph, constitute a Change of Control results from or arises out of a purchase or other acquisition of the Company, directly or indirectly, by a corporation or other entity in which the Executive has a greater than ten percent (10%) direct or indirect equity interest, such event shall not constitute a Change of Control.

3.    Employment Period. Subject to the terms and conditions hereof, the Company hereby agrees to continue the Executive in its employ, and the Executive hereby agrees to remain in the employ of the Company, for the period commencing on the Effective Date and ending on the last day of the thirty-sixth month following the month in which the Effective Date occurs (the "Employment Period").

4.    Terms of Employment.

(a)    Position and Duties.

(i)    During the Employment Period, (A) the Executive's position (including status, offices, titles and reporting requirements), authority, duties and responsibilities shall be at least commensurate in all material respects with the most significant of those held, exercised and assigned at any time during the 90-day period immediately preceding the Effective Date and (B) the Executive's services shall be performed at the location where the Executive was employed immediately preceding the Effective Date or any office or location less than 35 miles from such location.

(ii)    During the Employment Period, and excluding any periods of vacation and sick leave to which the Executive is entitled, the Executive agrees to devote her full business time to the business and affairs of the Company and, to the extent necessary to discharge the responsibilities assigned to the Executive hereunder, to use the Executive's reasonable best efforts to perform faithfully and efficiently such responsibilities. During the Employment Period it shall not be a violation of this Agreement for the Executive to (A) serve on corporate, civic or charitable boards or committees, (B) deliver lectures, fulfill speaking engagements or teach at educational institutions and (C) manage personal investments, so long as such activities do not significantly interfere with the performance of the Executive's responsibilities as an employee of the Company in accordance with this Agreement. It is expressly understood and agreed that to the extent that any such activities have been conducted by the Executive prior to the Effective Date, the continued conduct of such activities (or the conduct of activities similar in nature and scope thereto) subsequent to the Effective Date.

    (b)    Compensation.

(i)    Base Salary. During the Employment Period, the Executive shall receive an annual base salary ("Annual Base Salary"), which shall be paid monthly, having a value at least equal to twelve times the highest monthly base salary paid or payable to the

    -3-

Executive by the Company and its affiliated companies in respect of the twelve-month period immediately preceding the month in which the Effective Date occurs. During the Employment Period, the Annual Base Salary shall be reviewed at least annually and shall be increased at any time and from time to time as shall be substantially consistent with increases in base salary awarded in the ordinary course of business to other peer executives of the Company and its affiliated companies. Any increase in Annual Base Salary shall not serve to limit or reduce any other obligation to the Executive under this Agreement. Annual Base Salary shall not be reduced after any such increase and the term Annual Base Salary as utilized in this Agreement shall refer to Annual Base Salary as so increased. As used in this Agreement, the term "affiliated companies" includes any company controlled by, controlling or under common control with the Company.

(ii)    Annual Bonus. In addition to Annual Base Salary, the Executive shall be awarded, for each fiscal year during the Employment Period, an annual cash bonus (the "Annual Bonus"; which shall include, without limitation, any other annual cash bonus plan or program provided to Executive such as the Short Term Incentive Plan or any other similar plan, but shall not include any cash sign-on, relocation, retention or other special bonus or payments. ) in cash at least equal to the greater of (a) the average (annualized for any fiscal year consisting of less than twelve full months or with respect to which the Executive has been employed by the Company for less than twelve full months) bonus (the "Average Annual Bonus") paid or that has been earned and accrued, but unpaid to the Executive by the Company and its affiliated companies in respect of the three fiscal years immediately preceding the fiscal year in which the Effective Date occurs, (b) the Annual Bonus paid for the fiscal year immediately preceding the Effective Date, or (c) the target bonus associated with the Company achieving its 100 percent target payout level as determined in accordance with the terms of the Company’s bonus plans for senior executives for the fiscal year immediately preceding the Effective Date (the “Target Bonus”; the greater of clauses (a), (b) or (c) to be referred to as the “Highest Annual Bonus”); for the avoidance of doubt, the determination of bonus under clause (c) above shall not be reduced for the application of the Compensation Committee’s discretion to reduce such bonus or bonus funding, or increased to reflect additional amounts that may be paid or payable if the Company exceeds target. Each such Annual Bonus shall be paid no later than the 15th day of the third month of the fiscal year next following the fiscal year for which the Annual Bonus is awarded, unless the Executive shall elect to defer the receipt of such Annual Bonus pursuant to any nonqualified plan of the Company. Notwithstanding anything herein to the contrary, any portion of Annual Base Salary or Annual Bonus electively deferred by the Executive pursuant to a qualified or a non-qualified plan including, but not limited to, the Hologic, Inc. Deferred Compensation Plan or any successor thereto (“DCP”) shall be included in determining the Annual Base Salary, Annual Bonus and the Average Annual Bonus. If the fiscal year of any successor to this Agreement, as described by Section 11(c) herein, is different than the Company’s fiscal year at the time of the Change of Control, then the Executive shall be paid (i) the Annual Bonus that would have been paid upon the end of Company’s fiscal year ending after the Change of Control, and (ii) a pro-rata Annual Bonus for any months of service performed following the end of the Company’s fiscal year, but prior to the first day of the successor’s fiscal year immediately following the Change of Control. The Annual Bonuses thereafter shall be based on the successor’s first full fiscal year beginning after the Change of Control and successive fiscal years thereafter. “Pro

    -4-

Rata Bonus" shall mean an amount equal to the Bonus Amount (average of the Annual Bonuses paid or that has been earned and accrued, but unpaid during the three full fiscal years ended prior to the Date of Termination) multiplied by a fraction the numerator of which is the number of months worked in the fiscal year through the Date of Termination and the denominator of which is 12. Any partial months shall be rounded to the nearest whole number using normal mathematical convention.

(iii)    Incentive, Savings and Retirement Plans. In addition to Annual Base Salary and Annual Bonus payable as hereinabove provided, the Executive shall be entitled to participate during the Employment Period in all incentive, savings and retirement plans, practices, policies and programs applicable to other peer executives of the Company and its affiliated companies, but in no event shall such plans practices, policies and programs provide the Executive with incentive, savings and retirement benefits opportunities, in each case, less favorable, in the aggregate, than the most favorable of those provided by the Company and its affiliated companies for the Executive under such plans, practices, policies and programs as in effect at any time during the one-year immediately preceding the Effective Date, or, if more favorable to the Executive, those provided generally at any time after the Effective Date to other peer executives of the Company and its affiliated companies.

(iv)    Welfare Benefit Plans. During the Employment Period, the Executive and/or the Executive's family, as the case may be, shall be eligible for participation in and shall receive all benefits under welfare benefit plans, practices, policies and programs provided by the Company and its affiliated companies (including, without limitation, medical, prescription, dental, disability, salary continuance, employee life, group life, accidental death and travel accident insurance plans and programs) and applicable to other peer executives of the Company and its affiliated companies, but in no event shall such plans, practices, policies and programs provide benefits which are less favorable, in the aggregate, than the most favorable of such plans, practices, policies and programs in effect at any time during the one-year period immediately preceding the Effective Date, or, if more favorable to the Executive, those provided generally at any time after the Effective Date to other peer executives of the Company and its affiliated companies.

(v)    Expenses. During the Employment Period, the Executive shall be entitled to receive prompt reimbursement for all reasonable expenses incurred by the Executive upon submission of appropriate accountings in accordance with the most favorable policies, practices and procedures of the Company and its affiliated companies in effect at any time during the one-year period immediately preceding the Effective Date or, if more favorable to the Executive, as in effect at any time thereafter with respect to other peer executives of the Company and its affiliated companies.

(vi)    Fringe Benefits. During the Employment Period, the Executive shall be entitled to fringe benefits in accordance with the most favorable plans, practices, programs and policies of the Company and its affiliated companies in effect at any time during the one-year period immediately preceding the Effective Date or, if more

    -5-

favorable to the Executive, as in effect at any time thereafter with respect to other peer executives of the Company and its affiliated companies.

(vii)    Office and Support Staff. During the Employment Period, the Executive shall be entitled to an office or offices of a size and with furnishings and other appointments, and to exclusive personal secretarial and other assistance, at least equal to the most favorable of the foregoing provided to the Executive by the Company and its affiliated companies at any time during the one-year period immediately preceding the Effective Date or, if more favorable to the Executive, as provided at any time thereafter with respect to other peer executives of the Company and its affiliated companies.

(viii)    Vacation. During the Employment Period, the Executive shall be entitled to paid vacation of at least five (5) weeks and in accordance with the most favorable plans, policies, programs and practices of the Company and its affiliated companies as in effect at any time during the one-year period immediately preceding the Effective Date or, if more favorable to the Executive, as in effect at any time thereafter with respect to other peer incentives of the Company and its affiliated companies.

5.    Termination of Employment.

In such event, the Executive's employment with the Company shall terminate effective on the 30th day after receipt of such notice by the Executive (the "Disability Effective Date"), provided that, within the 30 days after such receipt, the Executive shall not have returned to full-time performance of the Executive's duties. For purposes of this Agreement, "Disability" means the absence of the Executive from the Executive's duties with the Company on a full-time basis for 180 consecutive business days as a result of incapacity due to mental or physical illness which is determined to be total and permanent by a physician selected by the Company or its insurers and acceptable to the Executive or the Executive's legal representative (such agreement as to acceptability not to be withheld unreasonably).

    (b)    Cause. The Company may terminate the Executive's employment during the Employment Period for "Cause". For purposes of this Agreement, "Cause" means (i) an act or acts of personal dishonesty taken by the Executive and intended to result in substantial personal enrichment of the Executive at the expense of the Company, (ii) repeated violations by the Executive of the Executive's obligations under Section 4(a) of this Agreement (other than as a result of incapacity due to physical or mental illness) which are demonstrably willful and deliberate on the Executive's part, which are committed in bad faith or without reasonable belief that such violations are in the best interests of the Company and which are not remedied in a reasonable period of time after receipt of written notice from the Company or (iii) the conviction of the Executive of a felony involving moral turpitude. The Company shall provide the

    -6-

Executive with 30 days written notice of any determination of Cause and provide the Executive, for a period of 30 days following such notice, with the opportunity to appear before the Board, with or without legal representation, to present arguments and evidence on her behalf and following such presentation to the Board, the Executive may only be terminated for Cause if the Board (excluding the Executive if she is a member of the Board), by unanimous consent reasonably determines in good faith that her actions did, in fact, constitute for Cause.

(iv)    A material change in the geographic location in which Executive’s principal office was located immediately prior to the Change of Control or, if applicable, the Date of Termination;

(v)    A material diminution in the budget over which the Executive had authority immediately prior to the of the Change of Control or, if applicable, the Date of Termination;

(vi)    Any other action or inaction that constitutes a material breach by the Company of this Agreement or any other agreement under which the Executive provides services;

provided, however, that Good Reason shall not exist unless the Executive has given written notice to the Company within ninety (90) days of the initial existence of the Good Reason event or condition(s) giving specific details regarding the event or condition; and unless the Company has had at least thirty (30) days to cure such Good Reason event or condition after the delivery of such written notice and has failed to cure such event or condition within such thirty (30) day cure period.

    (d)    Notice of Termination. Any termination by the Company for Cause or by the Executive for Good Reason shall be communicated by Notice of Termination to the other party hereto given in accordance with Section 13(b) of this Agreement. For purposes of this Agreement, a "Notice of Termination" means a written notice which (i) indicates the specific termination provision in this Agreement relied upon, (ii) to the extent applicable, sets forth in reasonable detail the facts and circumstances claimed to provide a basis for termination of the

    -7-

Executive's employment under the provision so indicated and (iii) if the Date of Termination (as defined below) is other than the date of receipt of such notice, specifies the termination date (which date shall be not more than fifteen days after the giving of such notice). The failure by the Executive or the Company to set forth in the Notice of Termination any fact or circumstance which contributes to a showing of Good Reason or Cause shall not waive any right of the Executive or the Company hereunder or preclude the Executive or the Company from asserting such fact or circumstance in enforcing the Executive's or the Company’s rights hereunder.

    (e)    Date of Termination. "Date of Termination" means the date of receipt of the Notice of Termination or any later date (taking into account any applicable notice and cure period) specified therein, as the case may be; provided however, that (i) if the Executive's employment is terminated by the Company other than for Cause, death or Disability, the Date of Termination shall be the date on which the Company notifies the Executive of such termination, and (ii) if the Executive's employment is terminated by reason of death or Disability, the Date of Termination shall be the date of death of the Executive or the Disability Effective Date, as the case may be.

6.    Obligations of the Company upon Termination.

considered to have remained employed until the end of the Employment Period and to have retired on the last day of such period), and (iv) payment to the Executive’s estate or beneficiary, as applicable, in a lump sum in cash within 30 days of the Date of Termination of an amount equal to the sum of the Executive’s Annual Base Salary and the Highest Annual Bonus.

If the Executive's employment shall be terminated by the Company for Cause or by the Executive other than for Good Reason (and other than by reason of her death or disability) during the Employment Period, this Agreement shall terminate without further obligations to the Executive other than the obligation to pay to the Executive Annual Base Salary through the Date of Termination. In such case, such amounts shall be paid to the Executive in a lump sum in cash within 30 days of the Date of Termination. The Executive shall, in such event, also be entitled to any benefits required by law that are not otherwise provided by this Agreement.

Except as provided in Section 6, nothing in this Agreement shall prevent or limit the Executive's continuing or future participation in any benefit, bonus, incentive or other plans, programs, policies or practices, provided by the Company or any of its affiliated companies and for which the Executive may qualify, nor shall anything herein limit or otherwise affect such rights as the Executive may have under any other agreements with the Company or any of its affiliated companies. Amounts which are vested benefits or which the Executive is otherwise entitled to receive under any plan, policy, practice or program of the Company or any of its affiliated companies at or subsequent to the Date of Termination shall be payable in accordance with such plan, policy, practice or program except as explicitly modified by this Agreement.

Following a Change of Control, the Company agrees to pay promptly as incurred, to the full extent permitted by law, all legal fees and expenses which the Executive may reasonably incur as a result of any contest (regardless of the outcome thereof) by the Company, the Executive or others of the validity or enforceability of, or liability under, any provision of this Agreement or any guarantee of performance thereof.

    (c)    If there shall be any dispute between the Company and the Executive (i) in the event of any termination of the Executive’s employment by the Company, whether such termination was for Cause, or (ii) in the event of any termination of employment by the Executive, whether Good Reason existed, then, unless and until there is a final, nonappealable judgment by a court of competent jurisdiction declaring that such termination was for Cause or that the determination by the Executive of the existence of Good Reason was not made in good faith, the Company shall pay all amounts, and provide all benefits, to the Executive and/or the Executive’s family or other beneficiaries, as the case may be, that the Company would be required to pay or provide pursuant to Section 6(d) as though such termination were by the Company without Cause, or by the Executive with Good Reason; provided, however, that the

    -11-

Company shall not be required to pay any disputed amount pursuant to this paragraph except upon receipt of an undertaking by or on behalf of the Executive to repay all such amounts to which the Executive is ultimately adjudged by such court not to be entitled.

9.    280G Protection.

(a)    In the event that the Executive shall become entitled to payment and/or benefits provided by this Agreement or any other amounts in the “nature of compensation” (whether pursuant to the terms of this Agreement or any other plan, arrangement or agreement with the Company, any person whose actions result in a change of ownership or effective control covered by Section 280G(b)(2) of the Internal Revenue Code (the “Code”) or any person affiliated with the Company or such person) as a result of such change in ownership or effective control (collectively the “Company Payments”), and such Company Payments will be subject to the tax (the “Excise Tax”) imposed by Section 4999 of the Code (and any similar tax that may hereafter be imposed by any taxing authority) the Company shall pay to the Executive the greater of the following, whichever gives the Executive the highest net after-tax amount (after taking into account federal, state, local and social security taxes at the maximum marginal rates) (x) the Company Payments or (y) one dollar less than the amount of the Company Payments that would subject the Executive to the Excise Tax. In the event that the Company Payments are required to be reduced pursuant to the foregoing sentence, then the Company Payments shall be reduced as mutually agreed between the Company and the Executive or, in the event the parties cannot agree, in the following order (1) any lump sum severance based on Base Salary or Annual Bonus, (2) any other cash amounts payable to the Executive, (3) any benefits valued as parachute payments; and (4) acceleration of vesting of any equity.

(b)    For purposes of determining whether any of the Company Payments will be subject to the Excise Tax and the amount of such Excise Tax, (x) the Company Payments shall be treated as “parachute payments” within the meaning of Section 280G(b)(2) of the Code, and all “parachute payments” in excess of the “base amount” (as defined under Code Section 280G(b)(3) of the Code) shall be treated as subject to the Excise Tax, unless and except to the extent that, in the opinion of the Company’s independent certified public accountants appointed prior to any change in ownership (as defined under Section 280G(b)(2) of the Code) or tax counsel selected by such accountants or the Company (the “Accountants”) such Company Payments (in whole or in part) either expressly do not constitute “parachute payments,” represent reasonable compensation for services actually rendered within the meaning of Section 280G(b)(4) of the Code in excess of the “base amount” or are otherwise not subject to the Excise Tax, and (y) the value of any non-cash benefits or any deferred payment or benefit shall be determined by the Accountants. All determinations hereunder shall be made by the Accountants which shall provide detailed supporting calculations both to the Company and the Executive at such time as it is requested by the Company or the Executive. If the Accountants determine that payments under this Agreement must be reduced pursuant to this paragraph, they shall furnish the Executive with a written opinion to such effect. The determination of the Accountants shall be final and binding upon the Company and the Executive.

    -12-

(c)    In the event of any controversy with the Internal Revenue Service (or other taxing authority) with regard to the Excise Tax, the Executive shall permit the Company to control issues related to the Excise Tax (at its expense), provided that such issues do not potentially materially adversely affect the Executive, but the Executive shall control any other issues. In the event the issues are interrelated, the Executive and the Company shall in good faith cooperate so as not to jeopardize resolution of either issue, but if the parties cannot agree the Executive shall make the final determination with regard to the issues. In the event of any conference with any taxing authority regarding the Excise Tax or associated income taxes, the Executive shall permit the representative of the Company to accompany the Executive, and the Executive and the Executive’s representative shall cooperate with the Company and its representative.

10.    Confidential Information. The Executive shall hold in a fiduciary capacity for the benefit of the Company all secret or confidential information, knowledge or data relating to the Company or any of its affiliated companies, and their respective businesses, which shall have been obtained by the Executive during the Executive's employment by the Company or any of its affiliated companies and which shall not be or become public knowledge (other than by acts by the Executive or representatives of the Executive in violation of this Agreement). After termination of the Executive's employment with the Company, the Executive shall not, without the prior written consent of the Company or as may otherwise be required by law or legal process, communicate or divulge any such information, knowledge or data to anyone other than the Company and those designated by it. In no event shall an asserted violation of the provisions of this Section 10 constitute a basis for deferring or withholding any amounts otherwise payable to the Executive under this Agreement.

11.    Successors.

(a)    This Agreement is personal to the Executive and without the prior written consent of the Company shall not be assignable by the Executive otherwise than by will or the laws of descent and distribution. This Agreement shall inure to the benefit of and be enforceable by the Executive's legal representatives.

    (b)    This Agreement shall inure to the benefit of and be binding upon the Company and its successors and assigns.

    (c)    The Company will require any successor (whether direct or indirect, by purchase, merger, consolidation or otherwise) to all or substantially all of the business and/or assets of the Company to assume expressly and agree to perform this Agreement in the same manner and to the same extent that the Company would be required to perform it if no such succession had taken place. The Company shall provide written evidence to the Executive to document compliance with the foregoing sentence within ten (10) business days of the Effective Date. As used in this Agreement, "Company" shall mean the Company as hereinbefore defined and any successor to its business and/or assets as aforesaid which assumes and agrees to perform this Agreement by operation of law, or otherwise. In addition, the Executive shall be entitled, upon exercise of any outstanding stock options or stock appreciation rights of the Company, to receive in lieu of shares of the Company’s stock, shares of such stock or other securities of such

    -13-

successor as the holders of shares of the Company’s stock received pursuant to the terms of the merger, consolidation or sale.

12.    Compliance With Section 409A of the Internal Revenue Code. To the extent applicable, it is intended that this Agreement comply with the provisions of Section 409A of the Code (hereinafter referred to as “Section 409A”). This Agreement shall be administered in a manner consistent with its intent, and any provision that would cause the Agreement to fail to satisfy Section 409A shall have no force and effect until amended to comply with Section 409A. Notwithstanding any provision of this Agreement to the contrary, in the event any payment or benefit hereunder is determined to constitute non-qualified deferred compensation subject to Section 409A, then to the extent necessary to comply with Section 409A, such payment or benefits shall not be made, provided or commenced until six (6) months after the Executive’s “separation from service” as such phrase is defined for the purposes of Section 409A.

13.Release. The Executive agrees that, with the exception of the Accrued Obligations due to her in accordance with the terms hereunder, that the payment of any severance under this Agreement to the Executive by the Company, is subject to and conditioned on Executive executing a general release of the Company in a form and scope determined by the Company in its sole discretion (the “Release Agreement”), without Executive revoking such Release Agreement within fifty-two (52) days of the Date of Termination (the “Consideration Period”) and provided that (a) if the Date of Termination occurs in one calendar year and the Consideration Period (including the payment date) expires during the following calendar year, then notwithstanding anything herein to the contrary, the payments of severance under Section 6(e) will be paid by the Company to the Executive in the second calendar year; (b) the Executive continues to comply with the provisions of the Non-Competition Agreement; and (c) prior to the expiration of the Consideration Period (i) Executive provides satisfactory evidence to the Company that she has returned all Company property, confidential information and documentation to the Company, and (ii) provides the Company with a signed written resignation of Executive’s status as an officer of the Company or any of its affiliates, if applicable.

14.    Miscellaneous.

(a)    This Agreement shall be governed by and construed in accordance with the laws of the Commonwealth of Massachusetts, without reference to principles of conflict of laws. The captions of this Agreement are not part of the provisions hereof and shall have no force or effect. This Agreement may not be amended or modified otherwise than by a written agreement executed by the parties hereto or their respective successors and legal representatives.

    (b)    All notices and other communications hereunder shall be in writing and shall be given by hand delivery to the other party or by registered or certified mail, return receipt requested, postage prepaid, addressed as follows:

    (c)    The invalidity or unenforceability of any provision of this Agreement shall not affect the validity or enforceability of any other provision of this Agreement.

    (d)    The Company may withhold from any amounts payable under this Agreement such Federal, state or local taxes as shall be required to be withheld pursuant to any applicable law or regulation.

    (e)    The Executive's or the Company’s failure to insist upon strict compliance with any provision hereof shall not be deemed to be a waiver of such provision or any other provision thereof.

    (f)    This Agreement contains the entire understanding of the Company and the Executive with respect to the rights and other benefits that the Executive shall be entitled during the Employment Period, and in connection therewith shall supersede all prior oral and written communications with the Executive with respect thereto; provided, however, that the Offer Letter, and Employee Intellectual Property Rights and Non-Competition Agreement, option or other equity agreements or other employment agreement by and between the Company and Executive shall remain in full force and effect and if the Company’s separation policy would provide greater benefits to the Executive than this Agreement, then the Executive may elect to receive benefits under the Company’s separation policy in lieu of the benefits provided hereunder. Nothing herein shall affect the application of the Company’s separation policy in lieu of the benefits provided hereunder. Nothing herein shall affect the application of the Company’s separation policy prior to the Effective Date.

    (g)    The Executive and the Company acknowledge that, except as may otherwise be provided under this Agreement or any other written agreement between the Executive and the Company, prior to the Effective Date, the employment of the Executive by the Company is “at will” and may be terminated by either the Executive or the Company at any time. Notwithstanding anything contained herein, if during or prior to the Employment Period, the Executive shall terminate employment with the Company other than for Good Reason, then the Executive shall have no liability to the Company.

Basis of Presentation

Basis of Presentation

The unaudited consolidated financial statements of Hologic, Inc. (“Hologic” or the “Company”) presented herein have been prepared pursuant to the rules of the Securities and Exchange Commission (the “SEC”) for quarterly reports on Form 10-Q and do not include all of the information and disclosures required by U.S. generally accepted accounting principles (“GAAP”) for annual financial statements. These unaudited financial statements should be read in conjunction with the consolidated financial statements and related notes for the fiscal year ended September 30, 2023 included in the Company’s annual report on Form 10-K filed with the SEC on November 21, 2023. In the opinion of management, the unaudited financial statements and notes contain all adjustments (consisting of normal recurring accruals and all other necessary adjustments) considered necessary for a fair presentation of the Company’s financial position, results of operations and cash flows for the periods presented.

The unaudited consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All intercompany transactions and balances have been eliminated in consolidation.

The preparation of financial statements in conformity with GAAP requires management to make significant estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting periods. Actual results could differ from management’s estimates if past experience or other assumptions do not turn out to be substantially accurate. Operating results for the three and six months ended March 30, 2024 are not necessarily indicative of the results to be expected for any other interim period or the entire fiscal year ending September 28, 2024. Fiscal 2023 was a 53-week fiscal year, and the additional week was included in the first quarter of fiscal 2023 consistent with the Company’s historical fiscal calendar.

Subsequent Events Consideration

The Company considers events or transactions that occur after the balance sheet date but prior to the issuance of the financial statements to provide additional evidence for certain estimates or to identify matters that may require additional disclosure. Subsequent events have been evaluated as required. There were no material recognized or unrecognized subsequent events, except as described below, affecting the unaudited consolidated financial statements as of and for the three and six months ended March 30, 2024.

On April 26, 2024, the Company executed an agreement to acquire Endomagnetics Ltd (“Endomag”) for a purchase price of approximately $310.0 million, subject to working capital and other customary adjustments. The closing is subject to certain regulatory approvals. Endomag, located in the UK, develops and sells breast surgery localization and lymphatic tracing technologies.

Leases

Lessor Activity - Leases where Hologic is the Lessor

Certain assets, primarily diagnostics instruments, are leased to customers under contractual arrangements that typically include an operating lease and performance obligations for disposables, reagents and other consumables. These contractual arrangements are subject to termination provisions which are evaluated in determining the lease term for lease accounting purposes. Contract terms vary by customer and may include options to terminate the contract or options to extend the contract. Where instruments are provided under operating lease arrangements, some portion or the entire lease revenue may be variable and subject to subsequent non-lease component (e.g., reagent) sales. Sales-type leases are immaterial. The allocation of revenue between the lease and non-lease components is based on stand-alone selling prices. Lease revenue represented less than 3% of the Company’s consolidated revenue for all periods presented.

Fair Value Measurement and Measurement Inputs, Recurring and Nonrecurring [Text Block]

Fair Value Measurements

Assets/Liabilities Measured and Recorded at Fair Value on a Recurring Basis

The Company has investments in money market funds, United States Treasury bills and commercial paper that are classified within Level 1 of the fair value hierarchy because they are valued using quoted market prices. These investments are classified as Cash and cash equivalents on the Consolidated Balance Sheets.

The Company also has investments in derivative instruments comprised of interest rate swaps and forward foreign currency contracts, which are valued using analyses obtained from independent third-party valuation specialists based on market observable inputs, representing Level 2 assets. The fair values of these derivative contracts represent the estimated amounts the Company would receive or pay to terminate the contracts. Refer to Note 11 for further discussion and information on derivative contracts. In addition, the Company has a contingent consideration liability that is recorded at fair value, which is based on Level 3 inputs.

The following table summarizes certain fair value information at March 30, 2024 and September 30, 2023 for investment assets and other liabilities measured at fair value on a recurring basis, as well as the carrying amount and amortized cost of certain investments.

Liabilities Measured and Recorded at Fair Value on a Recurring Basis

Changes in the fair value of recurring fair value measurements using significant unobservable inputs (Level 3), which solely consisted of contingent consideration liabilities, during the three and six month periods ended March 30, 2024 and April 1, 2023 were as follows:

		Three Months Ended				Six Months Ended

Assets Measured and Recorded at Fair Value on a Nonrecurring Basis

The Company remeasures the fair value of certain assets and liabilities upon the occurrence of certain events. Such assets are comprised of equity investments and long-lived assets, including property, plant and equipment, intangible assets and goodwill. During the second quarter of fiscal 2024, the Company recorded intangible asset impairment charges of $25.9 million and $0.9 million, respectively, related to its BioZorb developed technology and trade name intangible assets acquired in the Focal acquisition, which is within the Breast Health reportable segment (see Note 18 for further discussion), reducing the carrying value of the assets to $13.9 million and $0.5 million, respectively. During the first quarter of fiscal 2024, the Company recorded a $12.5 million impairment charge for right of use lease assets related to the planned closure of its Mobidiag facilities in Finland and France (see Note 8 for further discussion), reducing the carrying value to zero. In addition, during the first quarter of fiscal 2024, the Company recorded a $4.3 million impairment charge for an in-process research and development

project from the Mobidiag acquisition, reducing the carrying value of this asset to $22.4 million. There were no other remeasurements in the three and six months ended March 30, 2024 and April 1, 2023.

Disclosure of Fair Value of Financial Instruments

The Company’s financial instruments mainly consist of cash and cash equivalents, United States Treasury bills, commercial paper, accounts receivable, equity investments, interest rate swaps, forward foreign currency contracts, insurance contracts, accounts payable and debt obligations. The carrying amounts of the Company’s cash and cash equivalents, accounts receivable and accounts payable approximate their fair value due to the short-term nature of these instruments. The Company’s United States Treasury bills, commercial paper, interest rate swaps and forward foreign currency contracts are recorded at fair value. The carrying amount of the insurance contracts are recorded at the cash surrender value, as required by U.S. GAAP, which approximates fair value. The Company believes the carrying amounts of its equity investments approximate fair value.

The Company’s cash and cash equivalents, including current marketable securities, as of March 30, 2024 are as follows:

	Valuation								Balance Sheet Classification
in millions	Cost		Unrealized Gains		Unrealized Losses		Fair Value		Cash and cash equivalents		Investments
Cash	$	1,371.9	$	—	$	—	$	1,371.9	$	1,371.9	$	—

Total	$	2,179.9	$	0.1	$	—	$	2,180.0	$	2,180.0	$	—

The Company classifies its debt securities as available-for-sale and records them at fair value, with changes in fair value reported as a component of accumulated other comprehensive income (loss), which was immaterial for the period ended March 30, 2024. The Company periodically assesses these securities for potential impairment losses and credit losses. The amount of credit losses, if any, will be determined by comparing the difference between the present value of future cash flows expected to be collected on these securities and the amortized cost. There were no impairments and credit losses related to available-for-sale securities for the three and six months ended March 30, 2024.

The Company classifies all highly liquid investments with stated maturities of three months or less from the date of purchase as cash equivalents. The Company reviews the fair value hierarchy classification on a quarterly basis. Changes in the ability to observe valuation inputs may result in a reclassification of levels for certain securities within the fair value hierarchy. There were no transfers into or out of Level 3 during the three and six months ended March 30, 2024 and April 1, 2023, respectively. There were no sales of available-for-sale securities during the three and six months ended March 30, 2024.

The March 30, 2024 balance of available-for-sale debt securities by contractual maturity is shown in the following table. The fair value of the available-for-sale securities by maturity as of March 30, 2024 and September 30, 2023 are as follows:

	March 30, 2024		September 30, 2023
in millions	Fair Value		Fair Value
Due in three months or less	$	397.9	$	—
Total available-for-sale securities	$	397.9	$	—

Amounts outstanding under the Company’s 2021 Credit Agreement of $1.2 billion aggregate principal as of March 30, 2024 are subject to variable rates of interest based on current market rates, and as such, the Company believes the carrying amount of these obligations approximates fair value. The Company’s 4.625% Senior Notes due 2028 (the “2028 Senior Notes”) and 3.250% Senior Notes due 2029 (the “2029 Senior Notes”) had fair values of $385.9 million and $852.6 million, respectively, as of March 30, 2024 based on their trading prices, representing a Level 1 measurement.

Fiscal 2023 Acquisitions

JW Medical

On July 3, 2023, the Company completed the acquisition of assets from JW Medical Corporation (“JW Medical”) for a purchase price of $6.7 million. JW Medical was a long-standing distributor of the Company’s Breast Health products in South Korea. The majority of the purchase price was allocated to a customer relationship intangible asset with a useful life of 5 years.

Normedi

On April 3, 2023, the Company completed the acquisition of Normedi Nordic AS (“Normedi”) for a purchase price of $7.7 million. Normedi was a long-standing distributor of the Company’s Surgical products in the Nordics region of Europe. The purchase price included $1.1 million for contingent consideration based on incremental revenue growth over a 2-year measurement period. The Company allocated $3.0 million of the purchase price to a customer relationships intangible asset with a useful life of 5 years, and the excess of the purchase price over the net assets acquired was recorded to goodwill.

Contingent Consideration

The Company’s primary contingent consideration liability was related to its acquisition of Acessa Health, Inc. (“Acessa”), which was acquired in August 2020. Acessa developed the ProVu laparoscopic radiofrequency ablation system. The Company estimated the fair value of this liability to be $81.8 million as of the acquisition date. The contingent payments were based on a multiple of annual incremental revenue growth over a three-year period ending annually in December of each of 2021, 2022, and 2023. There was no maximum earnout. Pursuant to ASC 805, Business Combinations (ASC 805), the Company recorded its estimate of the fair value of the contingent consideration liability utilizing the Monte Carlo simulation based on future revenue projections of Acessa, revenue growth rates of comparable companies, implied volatility and applying a risk adjusted discount rate. Each quarter the Company was required to remeasure the fair value of the liability as assumptions change, and such adjustments were recorded in operating expenses. This fair value measurement was based on significant inputs not observable in the market and thus represented a Level 3 measurement as defined in ASC 820, Fair Value Measurements. This fair value measurement was directly impacted by the Company’s estimate of future incremental revenue growth of the business. Accordingly, if actual revenue growth were higher or lower than the estimates within the fair value measurement, the Company would record additional charges or gains. During the second quarter of fiscal 2023, the Company updated its forecasted revenue and recorded a gain of $12.4 million to record the liability at its fair value. The reduction in fair value was due to a decrease in forecasted revenues over the remaining measurement period at that time. During the three months ended December 30, 2023, the third and final measurement period was completed, and the Company recorded a loss of $1.7 million to increase the contingent consideration liability to fair value based on actual revenue results in the final earn-out period. The Company made a final payment of $2.6 million during the second quarter of fiscal 2024.

In accordance with ASC 810, Consolidation, and ASC 323, Investments - Equity Method and Joint Ventures, the Company determined that this investment should be accounted for under the equity method, which requires the Company to record its proportional share of the entity’s net income (loss). This investment is recorded within Other assets in the Consolidated Balance Sheets, and the Company’s proportionate share of Maverix’s net loss for the three and six months ended March 30, 2024 was immaterial.

Sale of SuperSonic Imagine Ultrasound Imaging Business

On September 29, 2023, the Company executed an agreement to sell its SSI ultrasound imaging business to SSH Holdings Limited for a sales price of $1.9 million in cash. Under the terms of the contract, the Company agreed to fund the SSI business with $33.2 million of cash. The sale was completed on October 3, 2023. The Company also agreed to provide certain transition services for up to one year, depending on the nature of the service. The SSI ultrasound imaging asset group met the criteria to be classified as assets held-for-sale in the fourth quarter of fiscal 2023. As a result, the Company recorded a charge of

$51.7 million in the fourth quarter of fiscal 2023 to record the asset group to its fair value less costs to sell pursuant to ASC 360, Property, Plant and Equipment-Impairment or Disposal of Long-Lived Assets.

The assets and liabilities of the disposed business at the date of disposition were as follows:

Assets:
Cash	$	33.2
Accounts receivable	4.5
Inventory	16.2
Prepaid expenses and other assets	8.6
Valuation allowance	(50.6)
Total assets disposed of	$	11.9
Liabilities:
Accounts payable	$	3.1
Accrued expenses	5.1
Total liabilities disposed of	$	8.2

The valuation allowance of $50.6 million was recorded to appropriately reflect the assets held-for-sale classification in the Consolidated Balance Sheet in the fourth quarter of fiscal 2023 relative to the loss recorded and the net tangible assets disposed.

The Company concluded that this disposal did not qualify as a discontinued operation as the sale of the SSI ultrasound imaging business was deemed to not be a strategic shift having or that will have a major effect on the Company’s operations and financial results.

Trade Receivables and Allowance for Credit Losses

Trade Receivables and Allowance for Credit Losses

The Company applies ASU No. 2016-13, Financial Instruments - Credit Losses (Topic 326) to its trade receivables and allowances for credit losses, which requires that financial assets measured at amortized cost be presented at the net amount expected to be collected. The expected credit losses are developed using an estimated loss rate method that considers historical collection experience, current conditions, and reasonable and supportable forecasts that affect the collectability of the reported amount. The estimated loss rates are applied to trade receivables with similar risk characteristics such as the length of time the balance has been outstanding and the location of the customer. In certain instances, the Company may identify individual trade receivable assets that do not share risk characteristics with other trade receivables, in which case the Company records its expected credit losses on an individual asset basis. For example, potential adverse changes to customer liquidity, such as the ongoing and possible future effects of global challenges including macroeconomic uncertainties, such as inflation, rising interest rates and availability of capital markets, and other economic disruptions. To date, the Company has not experienced significant customer payment defaults, or identified other significant collectability concerns. In connection with assessing credit losses for individual trade receivable assets, the Company considers significant factors relevant to collectability including those specific to the customer such as bankruptcy, length of time an account is outstanding, and the liquidity and financial position of the customer. If a trade receivable asset is evaluated on an individual basis, the Company excludes those assets from the portfolios of trade receivables evaluated on a collective basis.

The following is a rollforward of the allowance for credit losses as of March 30, 2024 compared to April 1, 2023:

Restructuring and Related Activities Disclosure

(8) Restructuring

During the first quarter of fiscal 2024, the Company further refined its strategy for the Mobidiag business, which is within the Diagnostics reportable segment. The strategy change included the decision to discontinue the manufacture and sale of certain products, closure of its facilities in Finland and France, and to move the development activities and operations to the Company’s San Diego, California location. As such, the Company determined certain fixed assets lives should be shortened and that lease assets were impaired at the affected facilities and recorded accelerated depreciation of $7.2 million and a lease asset impairment charge of $12.5 million. In connection with this plan, the Company finalized its decision to terminate the employees at these locations, totaling 190. The Company initiated discussions with the respective Works Councils at the end of the first quarter of fiscal 2024. In addition, the Company recorded the minimum statutory severance benefit for the employees located in France of $1.8 million pursuant to ASC 712, Compensation Nonretirement Postemployment Benefits. During the second quarter of fiscal 2024, the Company finalized its negotiations with the respective Works Councils and communicated the termination and related severance benefits to the affected employees. The Company has estimated the total severance charges, including accelerated stock compensation, to be approximately $12.2 million. The majority of the severance benefits will be recorded pursuant to ASC 420, Exit or Disposal Cost Obligations (ASC 420), which requires the severance benefits to be recognized ratably over the service period to obtain such benefits. The employees will cease employment in phases. During the second quarter of fiscal 2024, the Company recorded $4.0 million for severance benefits. This action is expected to be completed by the second quarter of fiscal 2025.

During the first quarter of fiscal 2022, the Company finalized its decision to close its Danbury, Connecticut facility where it manufactures its Breast Health capital equipment products. The manufacturing of the Breast Health capital equipment products and all other support services are in the process of being transferred to the Company’s Newark, Delaware facility. The transition is expected to be completed by the third quarter of fiscal 2025. In addition, research and development, sales and services support and administrative functions have been transferred to the Newark, Delaware and Marlborough, Massachusetts facilities. The employees were notified of the closure during the first quarter of fiscal 2022, and the majority of employees located in Danbury were given the option to relocate to the new locations. The Company is recording severance benefits ratably over the required service period pursuant to ASC 420. As a result, the Company recorded severance and benefits charges of $1.3 million and $1.8 million during the three and six months ended March 30, 2024, respectively, and $0.3 million and

$1.0 million during the three and six months ended April 1, 2023, respectively. The Company estimates that total severance charges, including retention, will be approximately $7.5 million.

2021 Credit Agreement

On September 27, 2021, the Company refinanced its then existing term loan and revolving credit facility with Bank of America, N.A. in its capacity as Administrative Agent, Swing Line Lender and L/C Issuer, and certain other lenders (the “2018 Credit Agreement”) by entering into a Refinancing Amendment (the “2021 Credit Agreement”). On August 22, 2022, the Company further amended the 2021 Credit Agreement to address the planned phase out of LIBOR by the UK Financial Conduct Authority. Under this amendment, the interest rates applicable to the loans under the 2021 Credit Agreement denominated in U.S. dollars were converted to a variant of the secured overnight financing rate (“SOFR”), as established from time to time by the Federal Reserve Bank of New York, plus a corresponding spread.

The 2021 Credit Agreement provided a $1.5 billion secured term loan facility (the “2021 Term Loan”) and a $2.0 billion revolving credit facility (the “2021 Revolver”). As of March 30, 2024, the principal amount outstanding under the 2021 Term Loan was $1.2 billion, and the interest rate was 6.43% per annum. No amounts were outstanding under the 2021 Revolver, and the full amount was available to be borrowed by the Company. During the first quarter of fiscal 2024, the Company made a $250.0 million voluntary prepayment on the 2021 Term Loan.

Interest expense, weighted average interest rates, and the interest rate at the end of period under the 2021 Credit Agreement were as follows: 

	Three Months Ended						Six Months Ended
	March 30, 2024			April 1, 2023			March 30, 2024			April 1, 2023
Interest expense	$	21.2		$	22.5		$	43.8		$	42.9

Interest rate at end of period	6.43		%	5.91		%	6.43		%	5.91		%

The Company’s effective interest rate swap agreements, the first of which fixed the SOFR component of the variable interest rate on $1.0 billion of aggregate principal under the 2021 Term Loan at 1.23% and terminated on December 17, 2023, and the second of which fixes the SOFR component of the variable interest rate on $500 million of aggregate principal under the 2021 Term Loan at 3.46% commencing on December 17, 2023 and terminating on December 27, 2024, resulted in the Company receiving $2.4 million and $12.0 million during the three and six months ended March 30, 2024, respectively, and $8.6 million and $15.2 million during the three and six months ended April 1, 2023, respectively. These amounts were recorded as a reduction to interest expense.

The 2021 Credit Agreement contains two financial covenants; a total leverage ratio and an interest coverage ratio, both of which are measured as of the last day of each fiscal quarter. These terms, and calculations thereof, are defined in further detail in the 2021 Credit Agreement. As of March 30, 2024, the Company was in compliance with these covenants.

2028 Senior Notes

As of March 30, 2024, the Company had 4.625% Senior Notes due 2028 (the “2028 Senior Notes”) outstanding in the aggregate principal balance of $400 million. The 2028 Senior Notes are general senior unsecured obligations of the Company and are guaranteed on a senior unsecured basis by certain of the Company’s domestic subsidiaries and mature on February 1, 2028.

2029 Senior Notes

As of March 30, 2024, the Company had 3.250% Senior Notes due 2029 (the “2029 Senior Notes”) outstanding in the aggregate principal balance of $950 million. The 2029 Senior Notes are general senior unsecured obligations of the Company and are guaranteed on a senior unsecured basis by certain of the Company’s domestic subsidiaries and mature on February 15, 2029.

Derivative Instruments and Hedging Activities Disclosure [Abstract]

Derivatives

Interest Rate Swaps - Cash Flow Hedge

The Company is exposed to certain risks arising from both its business operations and economic conditions. The Company manages its exposure to some of its interest rate risk through the use of interest rate swaps, which are derivative financial instruments. The Company does not use derivatives for speculative purposes. For a derivative that is designated as a

cash flow hedge, changes in the fair value of the derivative are recognized in accumulated other comprehensive income (“AOCI”) to the extent the derivative is effective at offsetting the changes in the cash flows being hedged until the hedged item affects earnings.

In fiscal 2019, the Company entered into an interest rate swap contract with an effective date of December 23, 2020 and a termination date of December 17, 2023 to hedge a portion of its variable rate debt. On August 25, 2022, the interest rate swap agreement was restructured (consistent with the 2021 Credit Agreement) to convert the benchmark interest rate from LIBOR to the SOFR rate effective September 23, 2022 with a termination date of December 17, 2023. The Company applied the practical and optional expedients in ASC 848, Reference Rate Reform, in evaluating the impact of modifying the contract, which resulted in no change to the accounting for this derivative contract. The notional amount of this swap was $1.0 billion. The restructured interest rate swap fixed the SOFR component of the variable interest rate on $1.0 billion of the notional amount under the 2021 Credit Agreement at 1.23%. The critical terms of the restructured interest rate swap were designed to mirror the terms of the Company’s SOFR-based borrowings under the 2021 Credit Agreement and therefore were highly effective at offsetting the cash flows being hedged. The Company designated this derivative as a cash flow hedge of the variability of the SOFR-based interest payments on $1.0 billion of principal. Therefore, changes in the fair value of the swap were recorded in AOCI. The contract ended during the first quarter of fiscal 2024 and as a result the fair value of this derivative was $0.0 million as of March 30, 2024.

On March 23, 2023, the Company entered into two consecutive interest rate swap contracts with the first contract having an effective date of December 17, 2023 and terminating on December 27, 2024, and the second contract having an effective date of December 27, 2024 and terminating on September 25, 2026. The notional amount of these swaps is $500 million, and the first interest rate swap fixes the SOFR component of the variable interest rate at 3.46%, and the second interest rate swap fixes the SOFR component of the variable interest rate at 2.98%. The critical terms of the interest rate swaps are designed to mirror the terms of the Company’s SOFR-based borrowings under the 2021 Credit Agreement and therefore are highly effective at offsetting the cash flows being hedged. The Company designated this derivative as a cash flow hedge of the variability of the SOFR-based interest payments on $500 million of principal. Therefore, changes in the fair value of the swap are recorded in AOCI. The fair value of these swaps was an asset position of $14.2 million as of March 30, 2024.

Forward Foreign Currency Exchange Contracts and Foreign Currency Option Contracts

The Company enters into forward foreign currency exchange contracts and foreign currency option contracts to mitigate certain operational exposures from the impact of changes in foreign currency exchange rates. Such exposures result from the portion of the Company’s cash and operations that are denominated in currencies other than the U.S. dollar, primarily the Euro, the UK Pound, the Australian dollar, the Canadian dollar, the Chinese Yuan and the Japanese Yen. These foreign currency contracts are entered into to support transactions made in the ordinary course of business and are not speculative in nature. The contracts are generally for periods of one year or less. The Company did not elect hedge accounting for these contracts; however, the Company may seek to apply hedge accounting in future scenarios. As of March 30, 2024 the notional amount was $190.3 million. The change in the fair value of these contracts is recognized directly in earnings as a component of other income (expense), net.

Realized and unrealized gains and losses from these contracts, which were the only derivative contracts not designated for hedge accounting, for the three and six months ended March 30, 2024 and April 1, 2023, respectively, were as follows:

	Three Months Ended				Six Months Ended

Litigation and Related Matters

On November 4, 2022, a product liability complaint was filed against the Company in Massachusetts state court by a group of plaintiffs who claim they sustained injuries caused by the BioZorb 3D Bioabsorbable Marker, and additional complaints were subsequently filed alleging similar claims. The BioZorb device is an implantable three-dimensional marker that helps clinicians overcome certain challenges presented by breast conserving cancer surgery (lumpectomy). The complaints allege that the plaintiffs suffered side effects that were not disclosed in the BioZorb instructions for use and make various additional claims related to the design, manufacture and marketing of the device. Complaints have been filed on behalf of 88 plaintiffs, one pending in Massachusetts state court, and the remainder in United States District Court for the District of Massachusetts. Discovery is ongoing. While the Company believes it has valid defenses and plans to vigorously defend its position, litigation can be costly and unpredictable, and at this early stage the Company cannot reasonably assess the outcome of this matter.

The Company is a party to various other legal proceedings, claims, governmental and/or regulatory inspections, inquiries and investigations arising out of the ordinary course of its business. The Company believes that except for those matters described above there are no other proceedings, claims, inspections, inquiries or investigations pending against it, the ultimate resolution of which are reasonably likely based upon management’s assessment, to have a material adverse effect on its financial condition or results of operations. It is possible that future results for any particular quarter or annual period may be materially affected by changes in our assumptions or the effectiveness of our strategies relating to these matters. In all cases, at each reporting period, the Company evaluates whether or not a potential loss amount or a potential range of loss is probable and reasonably estimable under ASC 450, Contingencies (ASC 450). Legal costs are expensed as incurred.

The Company granted options to purchase 0.6 million and 0.5 million shares of the Company’s common stock during the six months ended March 30, 2024 and April 1, 2023, respectively, with weighted-average exercise prices of $72.27 and $74.59, respectively. There were 4.5 million options outstanding at March 30, 2024 with a weighted-average exercise price of $54.63.

The Company uses a binomial model to determine the fair value of its stock options. The weighted-average assumptions utilized to value these stock options are indicated in the following table:

The Company granted 0.7 million and 0.6 million restricted stock units (“RSUs”) during the six months ended March 30, 2024 and April 1, 2023, respectively, with weighted-average grant date fair values of $72.00 and $74.44 per unit, respectively. In addition, the Company granted 0.1 million and 0.1 million performance stock units (“PSUs”) during the six months ended March 30, 2024 and April 1, 2023, respectively, to members of its senior management team, which have a weighted-average grant date fair value of $71.92 and $74.35 per unit, respectively. Each recipient of PSUs is eligible to receive between zero and 200% of the target number of shares of the Company’s common stock at the end of a three-year performance period, provided that the Company’s defined Return on Invested Capital metrics are achieved. The Company also granted 0.1 million and 0.1 million of FCF PSUs based on a three-year cumulative free cash flow measure (“FCF PSUs”) to members of its senior management team, which had a grant date fair value of $71.92 and $74.35 per unit during the six months ended March 30, 2024 and April 1, 2023, respectively. Each recipient of FCF PSUs is eligible to receive between zero and 200% of the target number of shares of the Company’s common stock at the end of the three-year measurement period. The PSUs and FCF PSUs cliff-vest three years from the date of grant, and the Company recognizes compensation expense ratably over the required service period based on its estimate of the probable number of shares that will vest upon achieving the measurement criteria. If there is a change in the estimate of the number of shares that are probable of vesting, the Company will cumulatively adjust compensation expense in the period that the change in estimate is made. The Company also granted 0.1 million and 0.1 million market-based awards (“MSUs”) to members of its senior management team during the six months ended March 30, 2024 and April 1, 2023, respectively. Each recipient of MSUs is eligible to receive between zero and 200% of the target number of shares of the Company’s common stock at the end of a three-year performance period based upon achieving a certain total shareholder return relative to a defined peer group. The MSUs were valued at $88.06 and $97.91 per share using the Monte Carlo simulation model in fiscal 2024 and 2023, respectively. The MSUs cliff-vest three years from the date of grant, and the Company recognizes compensation expense for the MSUs ratably over the service period. At March 30, 2024, there was 1.7 million in aggregate unvested RSUs, PSUs, FCF PSUs and MSUs outstanding.

At March 30, 2024, there was $14.4 million and $67.2 million of unrecognized compensation expense related to stock options and stock units (comprised of RSUs, PSUs, FCF PSUs and MSUs), respectively, to be recognized over a weighted-average period of 2.4 and 2.0 years, respectively.

Income Tax Disclosure [Abstract]

Income Taxes

Income Taxes

In accordance with ASC 740, Income Taxes, each interim period is considered integral to the annual period, and tax expense is measured using an estimated annual effective tax rate. An entity is required to record income tax expense each quarter based on its annual effective tax rate estimated for the full fiscal year and use that rate to provide for income taxes on a current year-to-date basis, adjusted for discrete taxable events that occur during the interim period.

For the three months ended March 30, 2024, the Company recorded income tax expense of $41.6 million resulting in an effective tax rate of 19.7%. For the six months ended March 30, 2024, the Company recorded an income tax benefit of $13.6 million, resulting in an effective tax rate of (3.4)%.

The effective tax rate for the three months ended March 30, 2024 was lower than the U.S. statutory tax rate primarily due to the U.S. deduction for foreign derived intangible income and the geographic mix of income earned by the Company’s international subsidiaries, which are generally taxed at rates lower than the U.S. statutory tax rate. The effective tax rate for the six months ended March 30, 2024 was lower than the U.S. statutory tax rate primarily due to a discrete tax benefit of $107.2 million related to a worthless stock deduction on the investment in one of the Company’s international subsidiaries recorded in the first quarter of fiscal 2024, the U.S. deduction for foreign derived intangible income, and the geographic mix of income earned by the Company’s international subsidiaries, which are generally taxed at rates lower than the U.S. statutory tax rate.

The Company recorded income tax expense of $60.8 million and $112.5 million for the three and six months ended April 1, 2023, resulting in effective tax rates of 21.8% and 21.7%, respectively.

The effective tax rates for the three and six months ended April 1, 2023 were higher than the U.S. statutory tax rate primarily due to increases to income tax reserves, the global intangible low-taxed income inclusion, and state income taxes, partially offset by the impact of the U.S. deduction for foreign derived intangible income, the geographic mix of income earned by the Company’s international subsidiaries, which are generally taxed at rates lower than the U.S. statutory tax rate, and federal and state tax credits.

Non-Income Tax Matters

The Company is subject to tax examinations for value added, sales-based, payroll and other non-income tax items. A number of these examinations are ongoing in various jurisdictions. The Company takes certain non-income tax positions in the jurisdictions in which it operates and records loss contingencies pursuant to ASC 450. Such amounts were not material for any of the periods presented. In the normal course of business, the Company's positions and conclusions related to its non-income tax positions could be challenged, resulting in assessments by governmental authorities. While the Company believes estimated losses previously recorded are reasonable, certain audits are still ongoing and additional charges could be recorded in the future.

The estimated remaining amortization expense of the Company’s acquired intangible assets as of March 30, 2024 for each of the five succeeding fiscal years was as follows:

Remainder of Fiscal 2024	$	97.8
Fiscal 2025	$	183.2
Fiscal 2026	$	153.3
Fiscal 2027	$	66.3
Fiscal 2028	$	63.2

During the second quarter of fiscal 2024, in connection with commencing its company-wide annual strategic planning process, the Company identified indicators of impairment in its BioZorb product line, which was part of the Focal acquisition. As a result, the Company performed an undiscounted cash flow analysis pursuant to ASC 360, Property, Plant and Equipment - Overall, to determine if the cash flows expected to be generated by the BioZorb product line over the remaining estimated useful life of the primary asset were sufficient to recover the carrying value of the asset group. Based on this analysis the undiscounted cash flows were not sufficient to recover the carrying value of the long-lived assets. Therefore, the Company was required to perform Step 3 of the impairment test and determine the fair value of the asset group. To estimate the fair value of the asset group, the Company utilized the income approach, which is based on a discounted cash flow (DCF) analysis and calculated the fair value by estimating the after-tax cash flows attributable to the asset group and then discounting the after-tax cash flows to present value using a risk-adjusted discount rate. Based on this analysis, the fair value of the BioZorb asset group was below its carrying value and the Company recorded an impairment charge of $26.8 million during the second quarter of fiscal 2024. The impairment charge was allocated to the long-lived assets on a pro-rata basis as follows: $25.9 million to developed technology and $0.9 million to trade names, which reduced the carrying value of the assets to $13.9 million and $0.5 million respectively. The Company also re-evaluated the remaining useful lives of the intangible assets and concluded no changes were necessary.

During the first quarter of fiscal 2024, the Company assessed its only in-process research and development intangible asset from its Mobidiag acquisition for impairment. The Company determined the fair value of this indefinite lived asset utilizing the DCF model and recorded a $4.3 million impairment charge, reducing the fair value of this asset to $22.4 million. The reduction in fair value of this asset was primarily due to a reduction in forecasted revenues and a delay in the timing of completing the project. In addition, the Company determined that the useful life of the customer relationship and trade name intangible assets from its Mobidiag acquisition should be shortened and recorded accelerated amortization expense of $7.3 million to bring the net carrying values to zero.

Revenue from Contract with Customer [Abstract]

Revenue

(2) Revenue

The Company accounts for revenue pursuant to ASC 606, Revenue from Contracts with Customer (ASC 606) and generates revenue from the sale of its products, primarily medical imaging systems and related components and software, diagnostic tests and assays and surgical disposable products, and related services, which are primarily support and maintenance services on its medical imaging systems, and to a lesser extent installation, training and repairs. In addition, the Company generates service revenue from performing laboratory testing services through its Biotheranostics CLIA laboratory, which is included in its Molecular Diagnostics business. The Company’s products are sold primarily through a direct sales force, and within international markets, there is more reliance on distributors and resellers. Revenue is recorded net of sales tax.

The Company considers revenue to be earned when all of the following criteria are met: the Company has a contract with a customer that creates enforceable rights and obligations; promised products or services are identified; the transaction price, or the amount the Company expects to receive, including an estimate of uncertain amounts subject to a constraint to ensure revenue is not recognized in an amount that would result in a significant reversal upon resolution of the uncertainty, is determinable; and the Company has transferred control of the promised items to the customer. A performance obligation is a promise in a contract to transfer a distinct good or service to the customer and is the unit of account in the contract. The transaction price for the contract is measured as the amount of consideration the Company expects to receive in exchange for the goods and services expected to be transferred. A contract’s transaction price is allocated to each distinct performance obligation and recognized as revenue when, or as, control of the distinct good or service is transferred. Transfer of control for the Company’s products is generally at shipment or delivery, depending on contractual terms, but occurs when title and risk of loss transfers to the customer which represents the point in time when the customer obtains the use of and substantially all of the remaining benefits of the product. As such, the Company’s performance obligation related to product sales is satisfied at a point in time. Revenue from support and maintenance contracts, extended warranty, and professional services for installation, training and repairs is recognized over time based on the period contracted or as the services are performed as these methods represent a faithful depiction of the transfer of goods and services.

The Company recognizes a receivable when it has an unconditional right to payment, which represents the amount the Company expects to collect in a transaction and is most often equal to the transaction price in the contract. Payment terms are typically 30 days in the U.S. but may be longer in international markets. The Company treats shipping and handling costs performed after a customer obtains control of the good as a fulfillment cost and records these costs within costs of product revenue when the corresponding revenue is recognized.

The Company also places instruments (or equipment) at customer sites but retains title to the instrument. The customer has the right to use the instrument for a period of time, and the Company recovers the cost of providing the instrument through the sales of disposables, namely tests and assays in Diagnostics and handpieces in GYN Surgical. These types of agreements include an embedded lease, which is generally an operating lease, for the right to use an instrument and no instrument revenue is recognized at the time of instrument delivery. The Company recognizes a portion of the revenue allocated to the embedded lease concurrent with the sale of disposables over the term of the agreement.

Revenue from laboratory testing services, which is generated by the Company’s Biotheranostics business, is recognized based upon contracted amounts with payors and historical cash collection experience for the same test or same payor group. Revenue is recognized once the laboratory services have been performed, the results have been delivered to the ordering physician, the payor has been identified, and insurance has been verified. The estimated timeframes for cash collection are three months for Medicare payors, six months for Medicare Advantage payors, and nine months for commercial payors.

Generally, the contracts for capital equipment include multiple performance obligations. For contracts with multiple performance obligations, the Company allocates the transaction price to each performance obligation using its best estimate of

the standalone selling price of each distinct good or service in the contract. The Company determines its best estimate of standalone selling price using average selling prices over 3- to 12-month periods of data depending on the products or nature of the services coupled with current market considerations. If the product or service does not have a history of sales or if sales volume is not sufficient, the Company relies on prices set by its pricing committees or applicable marketing department adjusted for expected discounts.

Variable Consideration

The Company exercises judgment in estimating variable consideration, which includes volume discounts, sales rebates, product returns and other adjustments. These amounts are recorded as a reduction to revenue and classified as a current liability. The Company bases its estimates for volume discounts and sales rebates on historical information to the extent it is reasonable to be used as a predictive tool of expected future rebates. To the extent the transaction price includes variable consideration, the Company applies judgment in constraining the estimated variable consideration due to factors that may cause reversal of revenue recognized. The Company evaluates constraints based on its historical and projected experience with similar customer contracts. The Company’s contracts for the sale of capital equipment and related components, and assays and tests typically do not provide the right to return product, however, its contracts for the sale of its GYN Surgical and Interventional Breast Solutions surgical handpieces provide for a right of return for a limited period of time. In general, estimates of variable consideration and constraints are not material to the Company’s financial statements.

Remaining Performance Obligations

As of March 30, 2024, the estimated revenue expected to be recognized in the future related to performance obligations that are unsatisfied was approximately $813.5 million. These remaining performance obligations primarily relate to support and maintenance obligations and extended warranty in the Company’s Breast Health and Skeletal Health reportable segments. The Company expects to recognize approximately 26% of this amount as revenue in fiscal 2024, 37% in fiscal 2025, 21% in fiscal 2026, 10% in fiscal 2027, and 6% thereafter. As permitted, the Company does not include remaining performance obligations related to contracts with original expected durations of one year or less in the amounts above.

Contract Assets and Liabilities

The Company discloses accounts receivable separately in the Consolidated Balance Sheets at their net realizable value. Contract assets primarily relate to the Company’s conditional right to consideration for work completed but not billed at the reporting date. Contract assets at the beginning and end of the period, as well as the changes in the balance, were immaterial.

Contract liabilities primarily relate to payments received from customers in advance of performance under the contract. The Company records a contract liability, or deferred revenue, when it has an obligation to provide service, and to a much lesser extent product, to the customer and payment is received or due in advance of performance. Deferred revenue primarily relates to support and maintenance contracts and extended warranty obligations within the Company’s Breast Health and Skeletal Health reportable segments. Contract liabilities are classified as other current liabilities and other long-term liabilities in the Consolidated Balance Sheets. The Company recognized revenue of $37.1 million and $101.6 million in the three and six months ended March 30, 2024, respectively, that was included in the contract liability balance at September 30, 2023. The Company recognized $34.5 million and $101.3 million in the three and six months ended April 1, 2023, respectively, that was included in the contract liability at September 24, 2022.

Practical Expedients

The Company applies a practical expedient to expense costs to obtain a contract with a customer as incurred when the amortization period would have been one year or less. These costs solely comprise sales commissions and typically the commissions are incurred at the time of shipment of product and upon billings for support and maintenance contracts.

Schedule of Estimated Amortization Expense

The estimated remaining amortization expense of the Company’s acquired intangible assets as of March 30, 2024 for each of the five succeeding fiscal years was as follows:

Remainder of Fiscal 2024	$	97.8
Fiscal 2025	$	183.2
Fiscal 2026	$	153.3
Fiscal 2027	$	66.3
Fiscal 2028	$	63.2

During the second quarter of fiscal 2024, in connection with commencing its company-wide annual strategic planning process, the Company identified indicators of impairment in its BioZorb product line, which was part of the Focal acquisition. As a result, the Company performed an undiscounted cash flow analysis pursuant to ASC 360, Property, Plant and Equipment - Overall, to determine if the cash flows expected to be generated by the BioZorb product line over the remaining estimated useful life of the primary asset were sufficient to recover the carrying value of the asset group. Based on this analysis the undiscounted cash flows were not sufficient to recover the carrying value of the long-lived assets. Therefore, the Company was required to perform Step 3 of the impairment test and determine the fair value of the asset group. To estimate the fair value of the asset group, the Company utilized the income approach, which is based on a discounted cash flow (DCF) analysis and calculated the fair value by estimating the after-tax cash flows attributable to the asset group and then discounting the after-tax cash flows to present value using a risk-adjusted discount rate. Based on this analysis, the fair value of the BioZorb asset group was below its carrying value and the Company recorded an impairment charge of $26.8 million during the second quarter of fiscal 2024. The impairment charge was allocated to the long-lived assets on a pro-rata basis as follows: $25.9 million to developed technology and $0.9 million to trade names, which reduced the carrying value of the assets to $13.9 million and $0.5 million respectively. The Company also re-evaluated the remaining useful lives of the intangible assets and concluded no changes were necessary.

During the first quarter of fiscal 2024, the Company assessed its only in-process research and development intangible asset from its Mobidiag acquisition for impairment. The Company determined the fair value of this indefinite lived asset utilizing the DCF model and recorded a $4.3 million impairment charge, reducing the fair value of this asset to $22.4 million. The reduction in fair value of this asset was primarily due to a reduction in forecasted revenues and a delay in the timing of completing the project. In addition, the Company determined that the useful life of the customer relationship and trade name intangible assets from its Mobidiag acquisition should be shortened and recorded accelerated amortization expense of $7.3 million to bring the net carrying values to zero.
