Chief Financial Officer at Tactile Systems
Thanks, Sherry. Unless noted otherwise, all references to fourth quarter financial results are on a GAAP and year over year basis. Total revenue in the fourth quarter increased $7,900,000 or 10.2% to $85,600,000 By product line, sales and rentals of lymphedema products, which includes our Flexitouch and Entre systems, increased $7,600,000 or 11% to $77,100,000 And sales of our airway clearance products, which includes our Afloves system increased 0.3% or 3.8% to $8,500,000 Continuing down the P and L, gross margin was 75.2% of revenue compared to 72.1% of revenue in the fourth quarter of twenty twenty three. The increase in gross margin was attributable primarily to lower manufacturing and warranty costs, a testament to improvements in product design and improving collections reflected in our revenue. Fourth quarter operating expenses increased $7,600,000 or 17.3% to $51,900,000 The change in GAAP operating expenses reflected a $2,600,000 increase in sales and marketing expenses, a 200,000 increase in research and development expenses and a $4,800,000 increase in reimbursement, general and administrative expenses, including and primarily driven by strategic technology investments.
