Q - Ceribell,

Previous wording

As of March 31, 2025, we had an accumulated deficit of $179.7 million. To date, we have funded our operations primarily through proceeds from the sale of shares of our stock, including common stock and redeemable convertible preferred stock, term loan proceeds, and cash generated from the sale of headbands and subscriptions. As of March 31, 2025, we had $182.7 million in cash and cash equivalents and short term marketable securities. Based on our current operating plan, we believe that the net proceeds from our IPO, together with the expected cash generated from revenue transactions with customers and our existing cash and cash equivalents, will be sufficient to fund our planned operating expenses and capital expenditure requirements for at least the next 12 months. We have based this estimate on assumptions that may prove to be wrong, and we could deplete our capital resources sooner than we expect. We may experience lower than expected cash generated from operating activities or greater than expected capital expenditures, cost of revenue, or operating expenses, and may need to raise additional capital to fund operations, further research and development activities, or acquire, invest in, or in-license other businesses, assets, or technologies.

Gross profit, or revenue less cost of revenue, and gross margin, or gross profit as a percentage of revenue, have been and will continue to be affected by various factors that may cause gross margins to fluctuate. These include the product mix between product and subscription revenues, potential changes to sales prices, the timing of our acquisition of new customers, renewals of and follow-on sales to existing customers, costs associated with third-party hosting fees, costs associated with third party manufacturing and supply chain purchases of inventory, and other direct costs such as tariffs and shipping. We expect our product inventory, currently located within the United States, to enable sufficient supply of finished goods through at least the third quarter of 2025. We do not expect any material impact to our financial results from incremental tariffs until at least the fourth quarter of 2025. Our gross margin may fluctuate from period to period, based upon the factors described above and in the section titled “Risk Factors” included elsewhere in this Quarterly Report on Form 10-Q.
