| **Common stock offered in this offering**  | 5,000,000 shares |
| **Underwriters' over-allotment option of common stock**  | We have granted the underwriters an option for a period of 30 days to purchase up to an additional 750,000 shares of our common stock solely to cover over-allotments. |

**USE OF PROCEEDS**

We estimate that the net proceeds from this offering will be approximately $64.8 million (or approximately $75.2 million if the underwriters exercise their over-allotment option in full), based on the initial public offering price of $15.00 per share, after deducting underwriting discounts and commissions and estimated offering expenses payable by us.

The principal purposes of this offering are to obtain capital to support our operations, to create a public market for our common stock and to facilitate our future access to the public equity markets. We currently intend to use the net proceeds from this offering as follows:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• approximately $55.0 million to scale up our commercial organization through the hiring of additional sales representatives and expansion of our commercial leadership team, as well as to invest in additional instrument sets to support volume growth and geographic expansion;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• approximately $7.5 million to fund the research and development of continued general innovation in our implant systems; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the remainder for working capital and other general corporate purposes.

We may also use a portion of the proceeds to acquire complementary businesses, products, services, or technologies. We periodically evaluate strategic opportunities; however, we have no current understandings or commitments to enter into any such acquisitions or make any such investments.

Based on our current operating plan, we believe that the estimated net proceeds from this offering, together with the expected cash generated from the sale of our systems, our existing cash, cash equivalents and marketable securities and amounts under our Trinity Loan Agreement and proceeds from the 2025 Convertible Notes, will be

------

sufficient to fund our planned operating expenses and capital expenditure requirements for at least the next 12 months.

This expected use of the net proceeds from this offering represents our intentions based on our current plans and business conditions, which could change in the future as our plans and business conditions evolve. We cannot predict with certainty all of the particular uses for the proceeds of this offering or the amounts that we will actually spend on the uses set forth above. Accordingly, our management will have broad discretion in applying the net proceeds from this offering. The timing and amount of our actual expenditures will be based on many factors, including cash flows from operations and the anticipated growth of our business. Pending their use, we intend to invest the net proceeds from this offering in a variety of capital-preservation investments, including government securities and money market funds.
