Third Quarter 2022 Financial Highlights

Revenues from product sales increased to $31.3 million for the three months ended September 30, 2022, from $26.3 million for the three months ended September 30, 2021, an increase of $5.0 million or 19%. This increase was primarily attributable to an increase in APD specialty product sales, which increased by $3.8 million as the result of increases in shortage product sales and product launches during 2022. 503B product sales increased by $1.0 million from additional product launches.

License fees and other revenue for the three months ended September 30, 2022, was $2.2 million, compared to $5.1 million for the same period in 2021, a decrease of $2.9 million.

Cost of sales for the three months ended September 30, 2022, totaled $27.7 million, an increase of $2.6 million, or 11%, as compared to $25.1 million for the three months ended September 30, 2021. The increase was primarily due to an increase of $1.5 million in cost of APD product sales and an increase of $1.1 million in cost of 503B product sales.

R&D expenses totaled $9.2 million for the three months ended September 30, 2022, a decrease of $8.5 million, or 48%, as compared to $17.7 million for the three months ended September 30, 2021. This decrease was primarily due to a decrease in costs of clinical and regulatory operations, compensation costs, drug licensing costs, cell therapy costs, and preclinical operations.

SG&A expenses totaled $9.4 million for the three months ended September 30, 2022, a decrease of $8.7 million, or 48%, as compared to $18.1 million for the three months ended September 30, 2021. The decrease was primarily due to a $5.2 million gain on change in earnout liability related to the Kuur contingent consideration, while 2021 had a $3.2 million loss on change in earnout liability. Additionally, there was a $1.4 million decrease in costs for preparing to commercialize Oral Paclitaxel. These decreases were partially offset by a $1.2 million increase in compensation-related and operating costs.

Interest expense totaled $6.3 million and $5.1 million, respectively, for the three months ended September 30, 2022, and 2021. Interest expense in 2022 was related to the Senior Credit

Agreement with Oaktree and the Royalty financing liability, while interest expense in 2021 was related to the Senior Credit Agreement only. The increase in interest expense during the three months ended September 30, 2022 was due to the Royalty interest financing carrying a higher effective interest rate.

Income tax expense for the three months ended September 30, 2022, amounted to $0.6 million, compared to $0.3 million expense for the same period in 2021. Income tax expense in the current period is primarily attributable to foreign income tax withholdings on our license revenue.

Net loss attributable to Athenex for the three months ended September 30, 2022, was $19.7 million, or ($0.14) per diluted share, as compared to a net loss of $36.1 million, or ($0.33) per diluted share, for the same period in 2021.

For further details on the Company’s financial results, including the results for the three months ended September 30, 2022, refer to the Form 10Q filed with the SEC.

2022 Financial Guidance

Athenex expects to maintain product sales growth in the range of 20-25% over the prior year period.

Cash Conservation Update
