−Removed: Several challenging macroeconomic factors persisted during the first quarter of fiscal 2024, including high interest rates, high inflation rates, and softening demand for discretionary capital asset purchases across the life sciences tools market. On the other hand, supply chain disruptions, labor shortages and resulting manufacturing difficulties that impacted business operations in fiscal year 2023 largely abated during the three months ended June 30, 2023.

+Added: Revenues from our reportable segments for the three and six months ended September 30, 2023 decreased 10% and 5%, respectively, largely due to softening demand for new capital equipment in the pharmaceutical markets, including lower demand for hardware sold by our Biopharmaceutical Development.
+Added: Revenues also decreased compared to the corresponding prior year periods due to the fiscal year 2023 loss of Sema4, a significant customer in our Clinical Genomics business. 
+Added: Although revenues were lower in the first two quarters of fiscal year 2024 compared to the prior year periods, gross profit as a percentage of revenues did not fall significantly due to our proactive cost containment efforts and favorable product mix.
+Added: Modest gross profit percentage declines of 2% and 1%, respectively, for the three and six months ended September 30, 2023 compared to the same periods in the prior year are primarily due to lower revenues on a partially fixed cost base, offset by our efforts to preserve our financial model.

Gross profit as a % of revenues
−Removed: Sterilization and Disinfection Control revenues increased 8% for the three months ended June 30, 2023 compared to the prior year period, primarily due to unusually low revenues during the three months ended June 30, 2022 attributable to labor shortages that delayed production and order fulfillment, which abated in the second half of fiscal year 2023. The division also benefited from price increases during the three months ended June 30, 2023.

Gross profit as a % of revenues
−Removed: Clinical Genomics revenues decreased 8% for the three months ended June 30, 2023 compared to the prior year period, primarily as a result of the loss of revenues from Sema4 and unfavorable changes to foreign currency exchange rates, partially offset by higher revenues in China, particularly hardware revenues.
−Removed: Gross profit percentage for the Clinical Genomics division decreased four percentage points for the three months ended June 30, 2023 compared to the prior year period, primarily due to lower revenues on a partially fixed cost base and to a lesser extent, unfavorable product mix. 
+Added: Clinical Genomics revenues decreased 16% and 12%, respectively, for the three and six months ended September 30, 2023 compared to the prior year periods, primarily as a result of the loss of revenues from Sema4 at the beginning of the third quarter of fiscal year 2023.
+Added: Excluding the loss of Sema4, revenues from our Clinical Genomics division would have been 3% lower during the three months ended September 30, 2023 compared to the prior year period, primarily due to the fact that China earned unusually high revenues during the three months ended September 30, 2022 upon reopening from COVID lockdowns.
+Added: Revenues would have been flat for the six months ended September 30, 2023 compared to the prior year period, excluding the loss of Sema4.

+Added: Although orders and revenues in China have been fairly strong in the first half of fiscal year 2024, we believe that ongoing macroeconomic slowdowns beginning in China may negatively affect our reported revenues and new orders in the second half of fiscal year 2024.

Gross profit as a % of revenues
−Removed: Biopharmaceutical Development revenues decreased 10% for the three months ended June 30, 2023 compared to the prior year period, primarily due to softening demand for capital equipment and to a lesser extent, unfavorable changes in foreign currency, partially offset by an increase in revenues from consumables.
−Removed: Given the current economic landscape related to softening demand for capital equipment, revenues for this segment are unlikely to grow at historical levels in fiscal year 2024. 
−Removed: While Biopharmaceutical Development's revenues decreased 10% for the three months ended June 30, 2023 compared to the prior year period, gross profit percentage remained flat, primarily due to a significant increase in consumables revenues, which have a higher gross margin as a percentage of revenues, and to a lesser extent price increases. 
+Added: Biopharmaceutical Development revenues decreased 24% and 17% for the three and months ended September 30, 2023 compared to the prior year period, primarily due to softening demand for capital equipment, partially offset by an increase in revenues from consumables and services as well as price increases.

+Added: Gross profit percentage for the three and six months ended September 30, 2023 decreased 2% and remained flat, respectively, compared to the prior year periods.
