“While we are not providing a specific guidance number for gross margin as a percent of sales, our expectations remain consistent, but we will maintain gross margin of approximately 80% on a non-GAAP basis as productivity gains and volumes are offset by pricing pressures and the cost of new manufacturing facilities.”

In context

“ering base period impact of the Mounjaro non-covered co-pay card dynamics will dampen these price declines in the first half of 2024, with more significant price declines expected in the second half of the year. During this year, we are taking a streamlined approach to our guidance line items related to expenses. Rather than provide three separate guidance line items for gross margin, research and development costs and marketing and sale and administrative costs, we are presenting a single new ratio representing our margin after planned costs, calculated by subtracting R&D costs and marketing and administrative costs from gross margin and dividing that figure by revenue. We express this ratio as a percentage, and for 2024, we expect it to be in the range of 31% to 33% on a non-GAAP basis. While we are not providing a specific guidance number for gross margin as a percent of sales, our expectations remain consistent, but we will maintain gross margin of approximately 80% on a non-GAAP basis as productivity gains and volumes are offset by pricing pressures and the cost of new manufacturing facilities. As for our expense growth across key categories, we expect marketing and administrative expenses to again grow in 2024 though at a slower pace than revenues, with growth driven by marketing investments in our recently launched and upcoming launch products. We also expect R&D expenses in 2024 to increase, driven by growing investments across all phases of our pipeline as we invest for the future, with the majority of dollar growth driven by ongoing and new late-phase opportunities. We expect R&D expense to increase at a higher rate than marketing, sell and administrative expenses. Other income and expense is expected to be between $400 million and $500 million of expense, primarily driven by higher interest expense. Turning to taxes; we expect our 2024 non-GAAP effective tax rate to be app”
