“Profitability for the quarter as measured by our primary metric of AOI excluding unusual items grew by 13.3% versus the prior year to $14,788. Versus prior year, gross profit percentage expanded by 80 bps but shrank by 240 bps when excluding the impact of non-cash charges. The contraction was primarily due to both product and geographical mix.” added Mr. Owens.

“Looking forward, solid sales funnels and a backlog build in 3Q25 will enable year over year core revenues growth in 4Q25. With the changes in administration in the USA, we are anticipating the need to potentially adapt to new policies, as well as the recent appreciation of the US dollar, and rising recession risk in Europe. We have a strong operating leverage profile, but we remain highly attuned to market shifts while continuing to invest in strategic initiatives as our operating results tend to change quickly in response to market conditions” concluded Mr. Owens.

* Total Net Leverage Ratio under our Credit Facility is defined as the ratio of total debt minus unrestricted cash in excess of $10 million as compared to 12 months trailing EBITDA. EBITDA, a non-GAAP metric, for purposes of this calculation, is defined as net income plus the sum of interest expense, income tax expense, depreciation, amortization, unusual or non-recurring non-cash charges and stock compensation expense. In addition, EBITDA gives effect to trailing 12 months pro-forma ownership of GKE and adds back certain GKE acquisition expenses for periods prior to the quarter ending December 31, 2024.

Total Net Leverage Ratios* as of March 31, 2024, June 30, 2024 and September 30, 2024 were 3.84x, 3.78x, and 3.59x, respectively.

Financial Results (unaudited, amounts in thousands, except per share data)

Total revenues were $62,840, an increase of 17.5% compared to 3Q24. Operating income increased 8,725% to $5,779. Net (loss) income was $(1,676), a decrease of 179% or $(0.31) per diluted share of common stock. Despite the increase in operating income, we incurred a net loss for the quarter due primarily to unrealized foreign currency losses and interest expense. On a non-GAAP basis, core organic revenues growth was 13.2% and AOI increased 21.2% to $14,515 or $2.67 per diluted share of common stock compared to 3Q24. As detailed in the Unusual Items table below, AOI for 3Q25 and 3Q24 was negatively impacted by unusual items totaling $273 and $1,080, respectively. Excluding the unusual items for 3Q25 and 3Q24, AOI would have increased 13.3% to $14,788. A reconciliation of non-GAAP measures is provided in the tables below.

Division Performance

Sterilization and Disinfection Control (37% of revenues in 3Q25) revenues were $23,507 for the quarter which resulted in core organic revenues growth of 8.2% versus the prior year. The acquisition of GKE drove overall quarterly growth to 21.6%. Excluding GKE, orders increased 13.1% and 8.5% for the quarter and nine months ended December 31, 2024, driven by strong commercial execution. The strong increase in orders drove an increase in past due backlog versus both September 30, 2024 and March 31, 2024. We expect to continue to ramp production during the fourth quarter and power increased organic growth in the coming months. Gross profit percentage for the quarter contracted by 210 bps versus the prior year primarily due to larger than normal sales made to certain distributors at lower than typical margins and unfavorable changes in foreign currency.

Calibration Solutions (23% of revenues in 3Q25) revenues were $14,429 which resulted in core organic revenues growth of 18.9% for the quarter. The increase in revenues was driven primarily by commercial momentum, particularly in our renal care product lines which we expect to continue in the near term and price increases. Gross profit percentage expanded by 170 bps primarily due to increased revenues and favorable product mix.

Biopharmaceutical Development (20% of revenues in 3Q25) revenues were $12,237 which resulted in core organic revenues growth of 31.3% for the quarter. The increase in revenues was driven by increased biopharmaceutical spending on capital equipment in North America and Europe which resulted in a 69.7% increase in revenues from hardware and software with prior year placements and installed base utilization increases driving 20.3% growth in consumables revenues versus prior year. Gross profit percentage decreased by 30 bps primarily due to unfavorable product mix.

Clinical Genomics (20% of revenues in 3Q25) revenues were $12,667 for the quarter, which resulted in core organic revenues growth of 1.9% for the quarter and an increase of 10.2% sequentially compared to 2Q25. The increase in revenues was driven primarily by strong consumables growth in North America, partially offset by decreased revenues in China. Sequential growth for the third consecutive quarter and improving sales funnels have us optimistic that the turnaround plan is gaining traction. Gross profit percentage expanded by 340 bps due to decreased amortization as a result of impairment charges taken during 4Q24. Excluding amortization expense, gross profit percentage would have decreased by 630 bps, primarily attributable to strategic lower margin instrument sales into our APAC region that should power consumables sales in the future.

Use of Non-GAAP Financial Measures

Adjusted operating income, adjusted operating income excluding unusual items, organic revenues growth and core organic revenues growth are non-GAAP measures that exclude or adjust for certain items, as detailed within the tables in “Supplemental Information Regarding Non-GAAP Financial Measures.” As noted below, we now include depreciation expense as a non-cash addback in the definition of adjusted operating income as it better aligns with presentations of other companies within our industry. All prior period amounts have been restated to conform with the current presentation.

¹ Core organic revenues growth, a non-GAAP measure, is defined as reported revenues growth excluding the impact of acquisitions and currency translation.

² The non-GAAP measures of adjusted operating income excluding unusual items and adjusted operating income excluding unusual items per diluted share are defined to exclude the non-cash impact of amortization of intangible assets acquired in a business combination, stock-based compensation, depreciation, impairment of goodwill and long-lived assets and unusual items. Unusual items are disclosed to highlight costs that are not ongoing and are incurred as a direct result of a specific transaction, such as the consummation of an acquisition, and are identified to allow investors to understand the Company’s expectation on an ongoing basis, following the completion of acquisition and integration activities. A reconciliation of these non-GAAP measures to their GAAP counterparts is set forth below, along with additional information regarding their use.

³ The non-GAAP measures of adjusted operating income and adjusted operating income per diluted share are defined to exclude the non-cash impact of amortization of intangible assets acquired in a business combination, stock-based compensation, depreciation and impairment of goodwill and long-lived assets. A reconciliation of these non-GAAP measures to their GAAP counterparts is set forth below, along with additional information regarding their use.

⁴ Organic revenues growth, a non-GAAP measure, is defined as reported revenues growth excluding the impact of acquisitions.

Financial Summary (Unaudited except for the information as of and for the year ended March 31, 2024)

Organic and Core Organic Revenues Growth (Unaudited)

Supplemental Information Regarding Non-GAAP Financial Measures

In addition to the financial measures prepared in accordance with generally accepted accounting principles (GAAP), we provide non-GAAP adjusted operating income, non-GAAP adjusted operating income per share amounts, non-GAAP adjusted operating income excluding unusual items, non-GAAP adjusted operating income excluding unusual items per share amounts, non-GAAP organic revenues growth, and non-GAAP core organic revenues growth in order to provide meaningful supplemental information regarding our operational performance. We believe that the use of these non-GAAP financial measures, in addition to GAAP financial measures, helps investors to gain a better understanding of our operating results, consistent with how management measures and forecasts its operating performance, especially when comparing such results to previous periods and to the performance of our competitors. Such measures are also used by management in their financial and operating decision-making and for compensation purposes.  This information facilitates management's internal comparisons to our historical operating results as well as to the operating results of our competitors. Since management finds this measure to be useful, we believe that our investors can benefit by evaluating both GAAP and non-GAAP results.

The non-GAAP measures of adjusted operating income and adjusted operating income per share presented in the reconciliation above are defined to exclude the non-cash impact of amortization of intangible assets acquired in a business combination, stock-based compensation, depreciation and impairment of goodwill and long-lived assets. To calculate adjusted operating income, we exclude, as applicable:

• Impairments of long-lived assets as such charges are outside of our normal operations and in most cases are difficult to accurately forecast.

• Stock-based compensation expense as it is a non-cash charge and costs calculated for this expense vary in accordance with the stock price on the date of grant.

• Depreciation expense as it is a non-cash charge.

• The expense associated with the amortization of acquisition-related intangible assets as a significant portion of the purchase price for acquisitions may be allocated to intangible assets that have lives of up to 20 years. Exclusion of amortization expense allows comparisons of operating results that are consistent over time for both our newly acquired and long-held businesses and with both acquisitive and non-acquisitive peer companies.

The non-GAAP measures of adjusted operating income and adjusted operating income per share presented in the reconciliation above are defined as Adjusted Operating Income less unusual items that are not on-going and are related to a specific transaction. We exclude these unusual items as they are outside of normal operations and are not on-going.

Our management recognizes that items such as amortization of intangible assets, stock-based compensation expense, depreciation expense and impairment losses on goodwill and long-lived assets can have a material impact on our operating and net income. To gain a complete picture of all effects on our profit and loss from any and all events, management does (and investors should) rely on the GAAP consolidated statements of operations. The non-GAAP numbers focus instead on our core operating business.

Readers are reminded that non-GAAP measures are merely a supplement to, and not a replacement for, or superior to, financial measures prepared according to GAAP. They should be evaluated in conjunction with the GAAP financial measures. Our non-GAAP information may be different from the non-GAAP information provided by other companies.
