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 months ended December 30, 2023 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 affecting the unaudited consolidated financial statements as of and for the three months ended December 30, 2023.

(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

10

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 December 30, 2023, the estimated revenue expected to be recognized in the future related to performance obligations that are unsatisfied was approximately $808.9 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 37% of this amount as revenue in fiscal 2024, 33% in fiscal 2025, 18% in fiscal 2026, 8% in fiscal 2027, and 4% 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 $64.4 million and $66.8 million in the three months ended December 30, 2023 and December 31, 2022, respectively, that was included in the contract liability balance at September 30, 2023 and September 24, 2022, respectively.

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.

(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 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 contingent consideration liabilities that are recorded at fair value, which is based on Level 3 inputs. The contingent consideration liability as of December 30, 2023 and December 31, 2022 was primarily related to the Acessa acquisition.

Assets and liabilities measured and recorded at fair value on a recurring basis consisted of the following at December 30, 2023: 

			Fair Value at Reporting Date Using
	Balance as of December 30, 2023		Quoted Prices in Active Market for Identical Assets (Level 1)		Significant Other Observable Inputs (Level 2)		Significant Unobservable Inputs (Level 3)

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 first quarter of fiscal 2024, the Company recorded a $12.5 million impairment charge for right of use lease assets related to the expected closure of facilities in the Diagnostics division (see Note 8 for further discussion). 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 fair value of this asset to $22.4 million. There were no other remeasurements in the three months ended December 30, 2023 and December 31, 2022.

Disclosure of Fair Value of Financial Instruments

The Company’s financial instruments mainly consist of cash and cash equivalents, 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 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.

Amounts outstanding under the Company’s 2021 Credit Agreement of $1.2 billion aggregate principal as of December 30, 2023 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 $386.3 million and $858.0 million, respectively, as of December 30, 2023 based on their trading prices, representing a Level 1 measurement. Refer to Note 9 for the carrying amounts of the various components of the Company’s debt.

(5) Business Combinations

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 includes $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 contingent consideration liability is primarily 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

13

would record additional charges or gains. 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. As of December 30, 2023, the contingent consideration liability related to Acessa was $2.6 million and the payment is expected to be made 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”), will be 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 loss for the three months ended December 30, 2023 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 $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 has determined 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, as a result of a change in strategy for a certain business within Diagnostics, including the discontinuation of the sale of certain products and expected closure of facilities, the Company determined certain fixed assets lives should be shortened and lease assets were impaired at the affected facilities. As such, the Company recorded accelerated depreciation of $7.2 million and a lease asset impairment charge of $12.5 million. The Company has initiated discussions with the respective Works Councils. In addition, the Company recorded the minimum statutory severance benefit for the affected employee groups of $1.8 million pursuant to ASC 712, Compensation Nonretirement Postemployment Benefits. The Company expects total severance benefits related to this action will be approximately $4.0 million to $8.0 million. This action is expected to be completed by the end of calendar 2024.

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. In addition, research and development, sales and services support and administrative functions are also transferring to the Newark, Delaware and Marlborough, Massachusetts facilities. The transition is expected to be completed by the third quarter of fiscal 2025. 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, Exit or Disposal Cost Obligations (ASC 420). As a result, the Company recorded severance and benefits charges of $0.5 million and $0.7 million during the three months ended December 30, 2023 and December 31, 2022, respectively. The Company estimates that total severance charges, including retention, will be approximately $5.9 million. In addition, in the first quarter of fiscal 2024, as part of exiting the building, the Company recorded facility restoration costs of $0.5 million.

(9) Borrowings and Credit Arrangements

The Company’s borrowings consisted of the following: 

	December 30, 2023		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:

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 December 30, 2023, the principal amount outstanding under the 2021 Term Loan was $1.2 billion, and the interest rate was 6.46% 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
	December 30, 2023			December 31, 2022
Interest expense	$	22.6		$	20.4
Weighted average interest rate	6.44		%	4.63		%
Interest rate at end of period	6.46		%	5.43		%

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 $9.7 million and $6.6 million during the three months ended December 30, 2023 and December 31, 2022, respectively, which was 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 December 30, 2023, the Company was in compliance with these covenants.

2028 Senior Notes

As of December 30, 2023, 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 December 30, 2023, 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.

16

Interest expense for the 2029 Senior Notes and 2028 Senior Notes was as follows:

			Three Months Ended
	Interest Rate		December 30, 2023		December 31, 2022
2028 Senior Notes	4.625	%	4.8		5.2
2029 Senior Notes	3.250	%	8.2		8.9
Total			$	13.0	$	14.1

(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 December 30, 2023 compared to December 31, 2022:

	Balance at Beginning of Period		Credit Loss		Write-offs, Payments and Foreign Exchange		Balance at End of Period
Three Months Ended
December 30, 2023	$	38.5	$	4.9	$	(0.3)	$	43.1
December 31, 2022	$	37.7	$	1.2	$	0.2	$	39.1

(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 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

17

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 December 30, 2023.

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 $8.2 million as of December 30, 2023.

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 December 30, 2023 the notional amount was $282.3 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 months ended December 30, 2023 and December 31, 2022, respectively, were as follows:

	Three Months Ended
	December 30, 2023		December 31, 2022

(12) Commitments and Contingencies

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 84 plaintiffs, one pending in Massachusetts state court, which has set a tentative November 2025 trial date, and the remainder in United States District Court for the District of Massachusetts. which has not set a trial date. 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 and claims arising out of the ordinary course of its business. The Company believes that except for those matters described above there are no other proceedings or claims pending against it, the ultimate resolution of which could have a material adverse effect on its financial condition or results of operations. 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 0.7 million and 0.6 million restricted stock units (“RSUs”) during the three months ended December 30, 2023 and December 31, 2022, respectively, with weighted-average grant date fair values of $71.90 and $74.30 per unit, respectively. In addition, the Company granted 0.1 million and 0.1 million performance stock units (“PSUs”) during the three months ended December 30, 2023 and December 31, 2022, 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 three months ended December 30, 2023 and December 31, 2022, 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 three months ended December 30, 2023 and December 31, 2022, 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 December 30, 2023, there was 1.7 million in aggregate unvested RSUs, PSUs, FCF PSUs and MSUs outstanding.

At December 30, 2023, there was $17.7 million and $86.7 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 2.3 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.

21

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 months ended December 30, 2023 and December 31, 2022. Segment information is as follows:

The Company operates in the following major geographic areas as noted in the below chart. Revenue data is based upon customer location. Other than the United States, no single country accounted for more than 10% of consolidated revenues. The Company’s sales in Europe are predominantly derived from the United Kingdom, Germany, France, Spain, Italy and the Netherlands. The Company’s sales in Asia-Pacific are predominantly derived from China, Australia and Japan. The “Rest of World” designation includes Canada, Latin America and the Middle East.

(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.

The Company’s effective tax rate for the three months ended December 30, 2023 was a benefit of 28.9% compared to a provision of 21.6% for the corresponding period in the prior year.

The effective tax rate for the three months ended December 30, 2023 was lower than the U.S. statutory tax rate primarily due to a $107.2 million discrete tax benefit related to a worthless stock deduction on the investment in one of the Company’s international subsidiaries.

The effective tax rate for the three months ended December 31, 2022 was higher than the U.S. statutory tax rate primarily due 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 our international subsidiaries, which are 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. 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.

Total intangible assets	$	5,352.1	$	4,519.4	$	5,342.0	$	4,453.4

The estimated remaining amortization expense of the Company’s acquired intangible assets as of December 30, 2023 for each of the five succeeding fiscal years was as follows:

Remainder of Fiscal 2024	$	151.5
Fiscal 2025	$	188.5
Fiscal 2026	$	158.6
Fiscal 2027	$	71.5
Fiscal 2028	$	68.5

During the first quarter of fiscal 2024, the Company assessed its only in-process research and development intangible asset from its Mobidiag Oy 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 trademark intangible assets from its Mobidiag acquisition should be shortened and recorded accelerated amortization expense of $7.3 million.

(21) Share Repurchase

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 the Company’s outstanding common stock, effective as of the close of trading September 23, 2022. This repurchase program replaced the previous $1.0 billion authorization. During the three months ended December 30, 2023 and December 31, 2022, the Company repurchased 2.2 million and 1.5 million shares of its common stock under the authorization for total consideration of $150.0 million and $100.0 million, respectively. As of December 30, 2023, $348.6 million remained available under this authorization.

On November 6, 2023, the Board of Directors authorized the Company to repurchase up to $500 million of the Company’s outstanding shares pursuant to an accelerated share repurchase (“ASR”) agreement. On November 15, 2023, the Company executed the ASR agreement with Goldman Sachs & Co. (“Goldman Sachs”) pursuant to which the Company agreed to repurchase $500 million of the Company’s common stock. In connection with the launch of the ASR, on November 17, 2023, the Company paid Goldman Sachs an aggregate of $500 million and received approximately 5.6 million shares of the Company’s common stock, representing 80% of the transaction value based on the Company’s closing share price on November 14, 2023. The final number of shares to be received under the ASR agreement will be determined upon completion of the transaction and will be based on the total transaction value and the volume-weighted average share price of the Company’s common stock during the term of the transaction. Final settlement of the transaction is expected to be completed in the second quarter of fiscal 2024.

(22) New Accounting Pronouncements

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 markers, localization, specimen radiology, connectivity solutions and breast conserving surgery products. Our most advanced breast imaging platforms, Selenia 3D Dimensions and 3Dimensions 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

27

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.

DISPOSITION

SuperSonic Imagine Ultrasound Imaging

On September 29, 2023, we executed an agreement to sell our SSI ultrasound imaging business to SSH Holdings Limited for a sales price of $1.9 million in cash. The sale was completed on October 3, 2023. We are providing 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, we recorded a charge of $51.7 million in the fourth quarter of fiscal 2023 to record the asset group at its fair value less costs to sell.

RESULTS OF OPERATIONS

All dollar amounts in tables are presented in millions.

We had a decrease in product revenues in the current quarter compared to the corresponding period in the prior year primarily due to the decrease in revenues in the Diagnostics business as COVID-19 assay sales declined significantly and the prior year period included an extra week based on our fiscal calendar. This decrease was partially offset by improved performance by our Breast Health division, as supply chain constraints impacted the prior year quarter and an increase in GYN Surgical revenue.

Diagnostics product revenues decreased $112.7 million, or 21.2%, in the current quarter compared to the corresponding period in the prior year primarily due to a decrease in Molecular Diagnostics revenues of $107.5 million and to a lesser extent, a decrease in Cytology & Perinatal revenue of $6.5 million, partially offset by an increase in Blood Screening of $1.2 million. Molecular Diagnostics’ product revenue was $292.9 million in the current three month period compared to $400.4 million in the corresponding period in the prior year. The decrease was primarily attributable to a decrease of $100.1 million 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, the increasing use of rapid tests and a decrease in average selling prices in international markets. We expect sales of our SARS-CoV-2 assays to continue to be significantly lower in fiscal 2024 compared to fiscal 2023. Within Cytology & Perinatal, in the current three month period we had a decrease in sales of our ThinPrep Pap Test from lower volumes in the U.S., which we primarily attribute to laboratories building up their inventories in the second half of fiscal 2023 which are now being worked down. We also experienced an increase in revenue from international sales denominated in foreign currencies from the favorable foreign currency exchange impact of the weakened U.S. dollar against a number of currencies.

Breast Health product revenues increased $50.2 million, or 27.5%, in the current quarter compared to the corresponding period in the prior year primarily due to an increase in volumes of our digital mammography systems, primarily 3D Dimensions systems and related workstation and workflow products, including software, an increase in Trident systems unit sales, and an increase in Affirm biopsy systems. The increase in volume was primarily driven by the supply chain constraints in the prior year related to electronic components, primarily semiconductor chips, which impacted our ability to manufacture sufficient quantities to meet customer demand. The increases in our breast imaging products were partially offset by lower sales of SSI ultrasound imaging products of $2.9 million as a result of the sale of this business in the beginning of the first quarter of fiscal 2024. We also had an increase in sales of our interventional breast solutions products of $6.8 million in the current quarter compared to the corresponding period in the prior year primarily driven by higher Tumark breast marker sales as we were able to fill backlog orders, and to a lesser extent Brevera needles and Eviva devices. We also implemented price increases in Europe across multiple products and experienced an increase in revenue from international sales denominated in foreign currencies from the favorable foreign currency exchange impact of the weakened U.S. dollar against a number of currencies.

GYN Surgical product revenues increased $5.8 million, or 3.8%, in the current quarter compared to the corresponding period in the prior year primarily due to increases in the sales volume of our MyoSure devices and Fluent Fluid Management products as procedure rates recovered from the impact of the COVID-19 pandemic. This was partially offset by a decrease in NovaSure devices, which we primarily attribute to an increase in the use of alternative treatments and competition.

Skeletal Health product revenues decreased $1.5 million, or 8.3%, in the current quarter compared to the corresponding period in the prior year primarily due to a decrease in sales volume of our Insight FD systems. This was partially offset by an increase in system upgrades and to a lesser extent an increase in sales of our Horizon DXA Systems.

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

	Three Months Ended
	December 30, 2023		December 31, 2022
United States	72.3	%	75.1	%
Europe	15.3	%	14.8	%
Asia-Pacific	6.5	%	6.1	%
Rest of World	5.9	%	4.0	%
	100.0	%	100.0	%

The percentage of product revenue derived from the U.S. decreased while Europe, Asia-Pacific, and Rest of World increased, which we primarily attribute to the decrease in the U.S. of 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, as discussed above. This was partially offset by an increase in the U.S. of Breast Health capital equipment sales and related workflow products including software. The percentage of product revenue increased in Europe, Asia-Pacific, and Rest of World in the current quarter primarily due to an increase in international Breast Health capital equipment and interventional breast solutions consumables sales and to a lesser extent Surgical sales, partially offset by a decrease in SARS-CoV-2 assay volumes. In addition, the percentage of product revenue in Europe, Asia-Pacific and Rest of World increased due to the favorable foreign currency exchange impact of the weakened U.S. dollar against a number of currencies.

Service and Other Revenues

Service and Other Revenues	$	185.0	18.3	%	$	187.9	17.5	%	$	(2.9)	(1.5)	%

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. The decrease in service and other revenue in the current quarter compared to the corresponding period in the prior year was primarily due to lower spare parts sales and to a lesser extent a decrease in service contracts primarily due to the extra week in the prior year period partially offset by an increase in installation and training revenue related to the increase in Breast Health capital equipment sales discussed above. Partially offsetting this decrease was a one-time $2.0 million milestone payment in the Surgical business in the current quarter.

	$	352.7	42.6	%	$	351.8	39.7	%	$	0.9	0.3	%

Cost of Product Revenues. The cost of product revenues as a percentage of product revenues was 37.1% in the current quarter compared to 33.4% in the corresponding period in the prior year. Cost of product revenues as a percentage of revenue increased in the current quarter 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 6.4% of total product revenue in the current quarter compared to 23.8% in the corresponding period in the prior year. This increase was partially offset by higher sales of our 3D Dimensions systems and related software products.

30

Diagnostics’ product costs as a percentage of revenue increased in the current quarter compared to the corresponding period in the prior year primarily due to lower sales of our SARS-CoV-2 assays, unfavorable manufacturing variances at a certain manufacturing facility, and lower ThinPrep Pap Test volumes which have higher margins. Partially offsetting this increase was an increase in volumes of our Women’s Health Aptima assays, lower inventory reserves and to a lesser extent lower international freight costs.

Breast Health’s product costs as a percentage of revenue decreased in the current quarter compared to the corresponding period 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 quarter was a decrease in inventory reserves and freight.

GYN Surgical’s product costs as a percentage of revenue increased in the current quarter compared to the corresponding period 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, and lower volumes of our NovaSure devices 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 decreased in the current quarter compared to the corresponding period in the prior year primarily due to an increase in volume of Horizon DXA systems and upgrades as well as a decrease in volume of Insight FD which has lower 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 quarter compared to the corresponding period 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 SSI, which was disposed of at the beginning of the first quarter of fiscal 2024.

Service and other revenues gross margin increased to 49.8% in the current quarter compared to 44.4% in the corresponding period in the prior year. The increase in the current quarter was primarily due to a decrease in service department costs related to the extra week in the prior year period, a decrease in time and material billings, which have lower margins compared to our service contract business, and an increase in license revenue from the one-time $2.0 million milestone payment in the Surgical business in the current quarter.

** Percentage not meaningful

Research and Development Expenses. Research and development expenses decreased 10.7% in the current quarter compared to the corresponding period in the prior year. The decrease in the current quarter was primarily due to a decrease in compensation and benefits as a result of additional expenses from the extra week in the prior year period, the elimination of expenses from SSI of $2.9 million from its disposal and lower headcount primarily in Breast Health. 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 decreased 8.9% in the current quarter compared to the corresponding period in the prior year. The decrease was 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 $2.2 million from its disposal, partially offset by higher commissions in our Breast Health division from an increase in sales.

General and Administrative Expenses. General and administrative expenses increased 3.0% in the current quarter compared to the corresponding period in the prior year. The increase in the current quarter was primarily due to an increase in compensation and benefits from higher stock compensation expense as a result of the 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 to us in the Minerva litigation, and an increase in bad debt expense of $3.7 million. These increases were partially offset by lower charges in the current quarter as the prior year quarter included an $8.9 million charge for a business dispute in connection with terminating the Mobidiag joint venture agreement in China, and a decrease in sales and use tax charges. In addition, we had a decrease in charitable donations of $5.0 million, 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 increased in the current quarter primarily due to accelerated amortization of customer relationship and tradename intangible assets acquired in the Mobidiag acquisition.

Impairment of Intangible Assets and Equipment. 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 are obligated to make contingent earn-out payments. The payments were 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

32

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.

Restructuring Charges. During the first quarter of fiscal 2024, as a result of a change in strategy for a certain business within Diagnostics, including the discontinuation of the sale of certain products and expected closure of facilities, we determined certain fixed assets lives should be shortened and lease assets were impaired at the affected facilities. As such, we recorded accelerated depreciation of $7.2 million and a lease asset impairment charge of $12.5 million. We have initiated discussions with the respective Works Councils. In addition, we recorded the minimum statutory severance benefit for the affected employee groups of $1.8 million. Additional severance benefit charges are expected to be recorded in fiscal 2024. For additional information, please refer to Note 8 to our consolidated financial statements.

	Amount		Amount		Amount		%
Interest Income	$	27.9	$	20.6	$	7.3	35.4	%

Interest income increased in the current quarter compared to the corresponding period in the prior year due to the increase in interest rates as the U.S. Federal Reserve had continually raised its Federal Funds Rate throughout our fiscal 2023 year, partially offset by lower average cash balances in the current quarter compared to the corresponding period in the prior year.

Interest Expense	$	(26.0)	$	(28.1)	$	2.1	(7.5)	%

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 decreased in the current quarter compared to the corresponding period in the prior year primarily due to an increase in amounts received under an interest rate swap agreement, which hedges the benchmark interest rate under our 2021 Credit Agreement, compared to the prior year period, and to a lesser extent a lower principal balance outstanding under our 2021 Credit Agreement, partially offset by the increase in the variable interest rate under our 2021 Credit Agreement.

For the first quarter of fiscal 2024, this account primarily consisted of net foreign currency exchange losses of $13.1 million primarily from the mark-to-market of foreign currency contracts used to hedge operating results, partially offset by a gain of $5.7 million from the change in cash surrender value of life insurance contracts related to our deferred compensation plan driven by stock market gains. For the first quarter of fiscal 2023, this account primarily consisted of net foreign currency exchange losses of $18.1 million, primarily from the mark-to-market of foreign currency contracts used to hedge operating results, partially offset by a gain of $2.5 million from the change in cash surrender value of life insurance contracts related to our deferred compensation plan driven by stock market gains.

**Percentage not meaningful

Our effective tax rate for the three months ended December 30, 2023 was a benefit of 28.9% compared to a provision of 21.6% for the corresponding period in the prior year. Our effective tax rate for the three months ended December 30, 2023 was lower than the U.S. statutory tax rate primarily due to a $107.2 million discrete tax benefit related to a worthless stock deduction on the investment in one of the Company’s international subsidiaries. Our effective tax rate for the three months ended December 31, 2022 was higher than the U.S. statutory tax rate primarily due 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 our international subsidiaries, which are 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

Operating Income	$	49.4		$	151.1		$	(101.7)	(67.3)	%
Operating Income as a % of Segment Revenue	11.0		%	27.0		%

Diagnostics revenues decreased in the current quarter compared to the corresponding period in the prior year primarily due to the decrease in product revenues discussed above.

Operating income for this business segment decreased in the current quarter compared to the corresponding period in the prior year primarily due to a decrease in gross profit from lower COVID-19 assay sales and an increase in operating expenses. Gross margin was 52.0% in the current quarter compared to 57.9% in the corresponding period in the prior year. The decrease in gross margin in the current period was primarily due to lower sales volumes of our SARS-CoV-2 assays which have a higher margin, unfavorable manufacturing variances at a certain manufacturing facility and lower sales volumes of our ThinPrep products, partially offset by increases in our Women's Health Aptima assay sales, a decrease in inventory reserves, a decrease in intangible asset amortization expense, and lower international freight.

Operating expenses increased in the current quarter compared to the corresponding period in the prior year primarily due to restructuring charges of $21.5 million, 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 and an increase in bad debt expense. 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 period included an additional week of expenses.

Operating Income	$	102.2		$	60.5		$	41.7	68.9	%
Operating Income as a % of Segment Revenue	27.1		%	18.1		%

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

Operating income for this business segment increased in the current quarter compared to the corresponding period in the prior year primarily due to an increase in gross profit from product sales and a decrease in operating expenses. Gross margin was 56.9% in the current quarter compared to 54.0% in the corresponding period in the prior year. The increase in gross margin is primarily due to higher volumes of our capital equipment, primarily 3D Dimensions, and related software sales and to a lesser extent a decrease in acquired intangible asset amortization due to impairments in the prior year and improved manufacturing utilization. Partially offsetting this increase was a decrease in service gross margin due to lower service contract revenue from the extra week in the prior year period.

Operating expenses decreased in the current quarter compared to the corresponding period in the prior year primarily due to a decrease in compensation and benefits from the extra week in the prior year period, the elimination of $6.3 million of expenses from the SSI disposition, a reduction in headcount in research and development, and a decrease in marketing initiatives and allocated charitable contributions. Partially offsetting these decreases were higher corporate allocations from an increase in stock compensation and expenses from our deferred compensation, and an increase in sales commissions from higher capital equipment sales.

Operating Income as a % of Segment Revenue	26.6		%	31.6		%

GYN Surgical revenues increased in the current quarter compared to the corresponding period in the prior year primarily due to the increase in product revenues discussed above.

Operating income for this business segment decreased in the current quarter compared to the corresponding period in the prior year primarily due to an increase in operating expenses partially offset by an increase in gross profit. Gross margin was 67.7% in the current quarter compared to 68.6% in the corresponding period in the prior year. 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, and a one-time milestone payment.

Operating expenses increased in the current quarter compared to the corresponding period in the prior year primarily due to a $7.4 million settlement awarded to us in the Minerva litigation in the corresponding prior year period, an increase in bad debt expense, and a loss of $1.7 million in the current quarter to increase the Acessa contingent consideration liability to fair value.

Skeletal Health revenues decreased in the current quarter compared to the corresponding period in the prior year primarily due to the decrease in product revenues discussed above.

Operating income for this business segment increased in the current quarter compared to the corresponding period in the prior year primarily due to an increase in gross profit partially offset by an increase in operating expenses. Gross margin was 38.5% in the current period, compared to 29.8% in the corresponding period in the prior year. The increase in gross margin was primarily due to higher sales volumes of our Horizon DXA and system upgrades, which have higher margins, as well as a decrease in volume of Insight FD, which has lower margins.

Operating expenses increased in the current quarter compared to the corresponding period in the prior year primarily due to an increase in third-party commissions partially offset by a decrease in compensation and benefits from the extra week in the prior year period.

LIQUIDITY AND CAPITAL RESOURCES

At December 30, 2023, we had $2,595.2 million of working capital and our cash and cash equivalents totaled $1,932.1 million. Our cash and cash equivalents decreased by $823.6 million during the first three 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 three months of fiscal 2024, our operating activities provided cash of $220.0 million, primarily due to net income of $246.5 million, non-cash charges for depreciation and amortization aggregating $88.4 million, stock-based compensation expense of $28.7 million, non-cash charges for unrealized foreign currency exchange losses of $13.6 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 $17.6 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 $157.8 million from changes in our operating assets and liabilities. The net cash outflow was primarily driven by an increase in prepaid income taxes of $70.1 million primarily due to the worthless stock deduction and to a lesser extent the timing of tax payments relative to the provision for income taxes, an increase of $38.2 million in accounts receivable due to higher sales in the first quarter of fiscal 2024 compared to the fourth quarter of fiscal 2023 as our days sales outstanding remained consistent, a $35.7 million decrease in accrued expenses primarily due to the payment of our annual bonuses and commissions partially offset by an increase in accrued interest based on the timing of payments, and an increase in inventory of $13.0 million to meet expected demand across our primary product lines. These cash outflows were partially offset by an increase of $7.2 million in accounts payable primarily due to the timing of payments.

In the first three months of fiscal 2024, our investing activities used cash of $104.2 million primarily due to capital expenditures of $38.0 million, which primarily consisted of the placement of equipment under customer usage agreements and purchase of manufacturing equipment and to a lesser extent building improvements, $34.5 million for the purchase of strategic equity investments and a $31.3 million net payment to sell our SSI ultrasound business.

In the first three months of fiscal 2024, our financing activities used cash of $943.8 million primarily due to $676.8 million for repurchases of our common stock, including a $500 million accelerated share repurchase program, $259.4 million for debt principal payments under our 2021 Credit Agreement, including a $250.0 million voluntary prepayment, and $16.2 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 $9.5 million from our equity plans.

Debt

We had total recorded debt outstanding of $2.56 billion at December 30, 2023, which was comprised of amounts outstanding under our 2021 Credit Agreement of $1.22 billion (principal of $1.23 billion), 2029 Senior Notes of $939.3 million (principal of $950.0 million), and 2028 Senior Notes of $397.0 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 $1.5 billion secured term loan (“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 December 30, 2023, there were no borrowings under the 2021 Revolver.

On August 22, 2022, we further amended the 2021 Credit Agreement (the “Third Amendment”) related to the planned phase out of LIBOR by the UK Financial Conduct Authority. Under this amendment, the interest rate 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”) plus an applicable spread.

Borrowings under the 2021 Credit Agreement, other than Swing Line Loans, 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 December 30, 2023, the interest rate under the 2021 Term Loan was 6.46% per annum.

We are also required to pay a quarterly commitment fee calculated on a daily basis equal to the Applicable Rate as of such day multiplied by the undrawn committed amount available under the Revolver. As of December 30, 2023, this commitment fee was 0.15% per annum for the 2021 Revolver.

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 December 30, 2023, 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 December 30, 2023, 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, 2023 through February 1, 2024 at 102.312% of par; 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.

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.

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. During the three months ended December 30, 2023, we repurchased 2.2 million of our common stock for total consideration of $150.0 million. As of December 30, 2023, $348.6 million remained available under this authorization.

On November 6, 2023, the Board of Directors authorized the Company to repurchase up to $500 million of our outstanding shares pursuant to an accelerated share repurchase (“ASR”) agreement. On November 15, 2023, we executed the ASR agreement with Goldman Sachs & Co. (“Goldman Sachs”) pursuant to which we agreed to repurchase $500 million of our common stock. In connection with the launch of the ASR, on November 17, 2023, we paid Goldman Sachs an aggregate of $500 million and received approximately 5.6 million shares of our common stock, representing 80% of the transaction value based on our closing share price on November 14, 2023. The final number of shares to be received under the ASR agreement will be determined upon completion of the transaction and will be based on the total transaction value and the volume-weighted average share price of our common stock during the term of the transaction. Final settlement of the transaction is expected to be completed in the second quarter of fiscal 2024.

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.

Legal Contingencies

We are currently involved in several legal proceedings and claims. In connection with these legal proceedings and claims, 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, 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, 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 value of our 2028 and 2029 Senior Notes was approximately $386.3 million and $858.0 million, respectively, as of December 30, 2023. Amounts outstanding under our 2021 Credit Agreement of $1.2 billion aggregate principal as of December 30, 2023 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. 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. Effective September 25, 2022 (the first day of fiscal 2023), 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 December 30, 2023, 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 $3.9 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.

The return from cash and cash equivalents will vary as short-term interest rates change. A hypothetical 10% increase in market interest rates would increase annual interest income by approximately $8.7 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, net on the mark-to-market of outstanding contracts and (ii) realized gains and losses recognized in other income, 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 December 30, 2023, 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 December 30, 2023.

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.

(1)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 the Company’s outstanding common stock, effective as of the close of trading on September 23, 2022. As of December 30, 2023, $348.6 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 of $71.94. The final number of shares to be received under the ASR agreement will be determined upon completion of the transaction and will be based on the total transaction value and the volume-weighted average share price of our common stock during the term of the transaction. Final settlement of the transaction is scheduled to be completed in the second quarter of fiscal 2024.

Item 5. Other Information

Basis of Presentation [Abstract]

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 months ended December 30, 2023 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 affecting the unaudited consolidated financial statements as of and for the three months ended December 30, 2023.

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 Disclosures [Abstract]

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 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 contingent consideration liabilities that are recorded at fair value, which is based on Level 3 inputs. The contingent consideration liability as of December 30, 2023 and December 31, 2022 was primarily related to the Acessa acquisition.

Assets and liabilities measured and recorded at fair value on a recurring basis consisted of the following at December 30, 2023: 

			Fair Value at Reporting Date Using
	Balance as of December 30, 2023		Quoted Prices in Active Market for Identical Assets (Level 1)		Significant Other Observable Inputs (Level 2)		Significant Unobservable Inputs (Level 3)

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 month periods ended December 30, 2023 and December 31, 2022 were as follows:

		Three Month Ended

	Contingent consideration recorded at acquisition	—		—
	Fair value adjustments	1.7		—
	Payments	—		—
Balance at end of period		$	3.7	$	23.4

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 first quarter of fiscal 2024, the Company recorded a $12.5 million impairment charge for right of use lease assets related to the expected closure of facilities in the Diagnostics division (see Note 8 for further discussion). 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 fair value of this asset to $22.4 million. There were no other remeasurements in the three months ended December 30, 2023 and December 31, 2022.

Disclosure of Fair Value of Financial Instruments

The Company’s financial instruments mainly consist of cash and cash equivalents, 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 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.

Amounts outstanding under the Company’s 2021 Credit Agreement of $1.2 billion aggregate principal as of December 30, 2023 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 $386.3 million and $858.0 million, respectively, as of December 30, 2023 based on their trading prices, representing a Level 1 measurement. Refer to Note 9 for the carrying amounts of the various components of the Company’s debt.

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 includes $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 contingent consideration liability is primarily 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 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. As of December 30, 2023, the contingent consideration liability related to Acessa was $2.6 million and the payment is expected to be made during the second quarter of fiscal 2024.

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 December 30, 2023 compared to December 31, 2022:

	Balance at Beginning of Period		Credit Loss		Write-offs, Payments and Foreign Exchange		Balance at End of Period

Restructuring and Related Activities Disclosure

(8) Restructuring

During the first quarter of fiscal 2024, as a result of a change in strategy for a certain business within Diagnostics, including the discontinuation of the sale of certain products and expected closure of facilities, the Company determined certain fixed assets lives should be shortened and lease assets were impaired at the affected facilities. As such, the Company recorded accelerated depreciation of $7.2 million and a lease asset impairment charge of $12.5 million. The Company has initiated discussions with the respective Works Councils. In addition, the Company recorded the minimum statutory severance benefit for the affected employee groups of $1.8 million pursuant to ASC 712, Compensation Nonretirement Postemployment Benefits. The Company expects total severance benefits related to this action will be approximately $4.0 million to $8.0 million. This action is expected to be completed by the end of calendar 2024.

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. In addition, research and development, sales and services support and administrative functions are also transferring to the Newark, Delaware and Marlborough, Massachusetts facilities. The transition is expected to be completed by the third quarter of fiscal 2025. 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, Exit or Disposal Cost Obligations (ASC 420). As a result, the Company recorded severance and benefits charges of $0.5 million and $0.7 million during the three months ended December 30, 2023 and December 31, 2022, respectively. The Company estimates that total severance charges, including retention, will be approximately $5.9 million. In addition, in the first quarter of fiscal 2024, as part of exiting the building, the Company recorded facility restoration costs of $0.5 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 December 30, 2023, the principal amount outstanding under the 2021 Term Loan was $1.2 billion, and the interest rate was 6.46% 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
	December 30, 2023			December 31, 2022
Interest expense	$	22.6		$	20.4
Weighted average interest rate	6.44		%	4.63		%
Interest rate at end of period	6.46		%	5.43		%

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 $9.7 million and $6.6 million during the three months ended December 30, 2023 and December 31, 2022, respectively, which was 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 December 30, 2023, the Company was in compliance with these covenants.

2028 Senior Notes

As of December 30, 2023, 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 December 30, 2023, the Company had 3.250% Senior Notes due 2029 (the “2029 Senior Notes”) outstanding in the aggregate principal balance of $950 million.

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 December 30, 2023.

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 $8.2 million as of December 30, 2023.

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 December 30, 2023 the notional amount was $282.3 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 months ended December 30, 2023 and December 31, 2022, respectively, were as follows:

	Three 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 84 plaintiffs, one pending in Massachusetts state court, which has set a tentative November 2025 trial date, and the remainder in United States District Court for the District of Massachusetts. which has not set a trial date. 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 and claims arising out of the ordinary course of its business. The Company believes that except for those matters described above there are no other proceedings or claims pending against it, the ultimate resolution of which could have a material adverse effect on its financial condition or results of operations. 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 0.7 million and 0.6 million restricted stock units (“RSUs”) during the three months ended December 30, 2023 and December 31, 2022, respectively, with weighted-average grant date fair values of $71.90 and $74.30 per unit, respectively. In addition, the Company granted 0.1 million and 0.1 million performance stock units (“PSUs”) during the three months ended December 30, 2023 and December 31, 2022, 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 three months ended December 30, 2023 and December 31, 2022, 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 three months ended December 30, 2023 and December 31, 2022, 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 December 30, 2023, there was 1.7 million in aggregate unvested RSUs, PSUs, FCF PSUs and MSUs outstanding.

At December 30, 2023, there was $17.7 million and $86.7 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 2.3 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.

The Company’s effective tax rate for the three months ended December 30, 2023 was a benefit of 28.9% compared to a provision of 21.6% for the corresponding period in the prior year.

The effective tax rate for the three months ended December 30, 2023 was lower than the U.S. statutory tax rate primarily due to a $107.2 million discrete tax benefit related to a worthless stock deduction on the investment in one of the Company’s international subsidiaries.

The effective tax rate for the three months ended December 31, 2022 was higher than the U.S. statutory tax rate primarily due 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 our international subsidiaries, which are 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. 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.

Fiscal 2028	$	68.5

During the first quarter of fiscal 2024, the Company assessed its only in-process research and development intangible asset from its Mobidiag Oy 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 trademark intangible assets from its Mobidiag acquisition should be shortened and recorded accelerated amortization expense of $7.3 million.

Share Repurchase

Share Repurchase

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 the Company’s outstanding common stock, effective as of the close of trading September 23, 2022. This repurchase program replaced the previous $1.0 billion authorization. During the three months ended December 30, 2023 and December 31, 2022, the Company repurchased 2.2 million and 1.5 million shares of its common stock under the authorization for total consideration of $150.0 million and $100.0 million, respectively. As of December 30, 2023, $348.6 million remained available under this authorization.

On November 6, 2023, the Board of Directors authorized the Company to repurchase up to $500 million of the Company’s outstanding shares pursuant to an accelerated share repurchase (“ASR”) agreement. On November 15, 2023, the Company executed the ASR agreement with Goldman Sachs & Co. (“Goldman Sachs”) pursuant to which the Company agreed to repurchase $500 million of the Company’s common stock. In connection with the launch of the ASR, on November 17, 2023, the Company paid Goldman Sachs an aggregate of $500 million and received approximately 5.6 million shares of the Company’s common stock, representing 80% of the transaction value based on the Company’s closing share price on November 14, 2023. The final number of shares to be received under the ASR agreement will be determined upon completion of the transaction and will be based on the total transaction value and the volume-weighted average share price of the Company’s common stock during the term of the transaction. Final settlement of the transaction is expected to be completed in the second quarter of fiscal 2024.

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 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

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 December 30, 2023, the estimated revenue expected to be recognized in the future related to performance obligations that are unsatisfied was approximately $808.9 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 37% of this amount as revenue in fiscal 2024, 33% in fiscal 2025, 18% in fiscal 2026, 8% in fiscal 2027, and 4% 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 $64.4 million and $66.8 million in the three months ended December 30, 2023 and December 31, 2022, respectively, that was included in the contract liability balance at September 30, 2023 and September 24, 2022, respectively.

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 December 30, 2023 for each of the five succeeding fiscal years was as follows:

Remainder of Fiscal 2024	$	151.5
Fiscal 2025	$	188.5
Fiscal 2026	$	158.6
Fiscal 2027	$	71.5
Fiscal 2028	$	68.5

During the first quarter of fiscal 2024, the Company assessed its only in-process research and development intangible asset from its Mobidiag Oy 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 trademark intangible assets from its Mobidiag acquisition should be shortened and recorded accelerated amortization expense of $7.3 million.
