Beta Bionics, Inc.

Net Sales

In May 2023, the iLet was cleared by the FDA for the treatment of T1D and we began commercializing the iLet in the United States. We generate product revenue from the sale of the iLet and single-use products that are used together with the iLet, including cartridges for storing and delivering insulin, and infusion sets that connect the insulin pump to a user’s body. We are able to recognize revenue when control of the promised goods and services is passed to the customer, which we have identified as our distributor and pharmacy partners. Revenue is recognized in the amount of the consideration received net of any estimated returns and estimated variable consideration adjustments, including rebates, chargebacks and patient assistance, all of which differ by product and sales mix. Revenue is recognized either over time or at a point in time, depending on when control of the associated performance obligation is transferred to the customer.

Cost of Sales

Cost of sales includes raw materials, labor costs, manufacturing overhead expenses, royalties, freight, import tariffs, scrap and reserves for expected warranty costs and excess and obsolete inventory. Manufacturing overhead expenses include expenses relating to manufacturing engineering, material procurement, inventory and quality control, facilities, depreciation, amortization, information technology and operations supervision and management.

Gross Profit and Gross Margin

Gross profit and gross margin, or gross profit as a percentage of revenue, has been and will continue to be affected by various factors, including the timing of new patient adoption, iLet and associated single-use products sales, reimbursement, length of product usage, our introduction of new products, including the costs associated with producing and bringing those new products to market, cost reduction and operational efficiency. As a result of the small revenue recognized at or around the date the iLet is sold in the PBP channel, we absorb initial negative gross margin. iLet sales in the PBP channel are generally expected to start generating cumulative positive gross margin for us beyond the third month the user uses the iLet and continues to purchase single-use products. Given the differences in the timing and amount of outlays which correlate directly to revenue between the DME and PBP channels, changes in our future sales mix may also impact our gross profit and gross margin.

Operating Expenses

Our operating expenses consist of (i) research and development expenses, (ii) sales and marketing expenses and (iii) general and administrative expenses.

Research and Development

Our research and development expenses primarily consist of engineering and research expenses related to the iLet clinical trials, regulatory expenses and personnel-related expenses, such as salaries, bonuses, stock-based compensation expense and benefits for our employees in the research and development function. We also incur research and development expenses for payments made under third-party licensing agreements, supplies, development prototypes, outside design and testing services, depreciation, allocated facilities and information services, clinical trial costs, and other indirect costs. We expense research and development costs as incurred. In the first quarter of 2025, we began to track research and development expenses by individual product candidate.

Investigational devices in later stages of clinical development generally have higher development costs than those in earlier stages of clinical development, primarily due to the increased size and duration of later-stage clinical trials. We expect our research and development expenses to increase significantly for the foreseeable future as we advance our current clinical development activities, develop the bihormonal configuration of the iLet, develop the patch pump, and if we pursue the development of the iLet for expanded patient populations and indications such as people with T2D. We expect our research and development expenses to also increase significantly for the foreseeable future as we hire and retain additional personnel, including research, clinical, development, manufacturing, regulatory and scientific personnel; remit payments to third parties through license arrangements; and develop, establish and validate our commercial-scale and manufacturing process.

Sales and Marketing

We are in the early commercialization stages of the iLet and are focused on driving awareness and adoption among new customers. Sales and marketing expenses are primarily related to the market development and post-commercial launch activities for the iLet, including the design of infrastructure to support the customer experience, and marketing and branding strategy. Market development and post-commercial launch activities account for a significant portion of our overall operating expenses and are expensed as they are incurred. We anticipate a significant increase in sales and marketing expenses for the foreseeable future to support the continued commercialization of the iLet.

Our sales and marketing expenses primarily consist of personnel-related costs, including salaries, sales incentive compensation, stock-based compensation expense and benefits for our sales representatives, field clinical specialists, and other sales and marketing personnel. We additionally incur expenses related to healthcare conference exhibits and market research, market access expenses, including payor education to support the future commercialization of the iLet, costs for secondary data purchases of patient claims and prescription data, website development and consulting fees. Other expenses include facilities, depreciation and other expenses, which include direct and allocated expenses for rent and maintenance of facilities, as well as travel expenses.

General and Administrative

General and administrative expenses primarily consist of personnel-related costs, including salaries, bonuses, stock-based compensation expense and benefits for our personnel in executive, legal, finance and accounting, human resources, information technology, quality assurance and other administrative roles. We additionally incur expenses related to patent filings, legal fees for patent and corporate matters, as well as other professional fees for accounting, auditing, consulting and tax services. Other expenses include insurance, travel, facilities, depreciation and other expenses not otherwise included in research and development or sales and marketing expenses. We anticipate a significant increase in general and administrative expenses for the foreseeable future due to additional costs associated with operating as a public company. These include increased expenses for professional services, director and officer insurance, investor and public relations and compliance with SEC rules and regulations and exchange listing standards.

Other Income (Expense)

Our other income (expense) consists of (i) interest income, (ii) other income (expense) and (iii) change in fair value of warrant liabilities.

Interest Income

Interest income consists of cash interest earned on our cash, cash equivalents and short-term and long-term investment balances.

Other Income (Expense)

Other income (expense) consists of miscellaneous income unrelated to our core operations.

Change in Fair Value of Warrant Liabilities

In connection with our February 2022 Series C preferred stock financing, we granted warrants (Series C Warrants) to certain investors to purchase additional shares of our Series C convertible preferred stock. In connection with our August 2023 Series D preferred stock financing, we granted warrants to certain investors to purchase shares of our Class B common stock (Class B Warrants, and together with the Series C Warrants, the Warrants). These Warrants were classified as liabilities on our balance sheet and initially recorded at fair value on the grant date. They are subsequently remeasured to fair value at the end of each reporting period, with changes in the fair value recognized as a component of other income (expense), net. We continued to recognize changes in fair value of the warrant liabilities until the Warrants were exercised prior to the completion of our IPO. The Warrants are no longer outstanding. For additional information, see Note 4 of our unaudited condensed financial statements included elsewhere in this Quarterly Report.
