RxSight, Inc. Reports Third Quarter 2023 Financial Results

Aliso Viejo, Calif. (NASDAQ: RXST) – November 9, 2023 – RxSight, Inc., an ophthalmic medical device company dedicated to providing high-quality customized vision to patients following cataract surgery, today reported financial results for the three and nine months ended September 30, 2023.

Key Quarterly Highlights

“LAL procedure volumes continued their positive advance in the third quarter, while favorable LDD placement trends provided an encouraging indicator of continued LAL procedure growth in future periods,” said Ron Kurtz, Chief Executive Officer and President of RxSight. “The post-operative adjustability of the LAL sets it apart from any other premium lens on the market today and makes it an increasingly popular choice for the precise, high-quality vision it provides across a range of distances. We remain optimistic about the future potential of our unique technology to reshape and expand the premium cataract market, while delivering long-term value to patients, doctors and shareholders.”

Third Quarter Financial Results

In the third quarter of 2023, total revenue was $22.2 million, an increase of 76% compared to $12.6 million in the third quarter of 2022. Revenue growth was driven by a 39% increase in LDD revenue and a 107% increase in LAL revenue compared to the third quarter of 2022.

Gross profit for the third quarter of 2023 was $13.7 million, or 61.9% of revenue, an increase of $8.4 million or 156.4% compared to gross profit of $5.4 million, or 42.5% of revenue, for the third quarter of 2022.

Total operating expenses for the third quarter of 2023 were $26.2 million, a 23.1% increase from $21.3 million in the third quarter of 2022, reflecting the company’s ongoing investments to grow its LDD installed base and support increased LAL procedure volumes.

Non-GAAP Financial Measures

To supplement our unaudited condensed consolidated financial statements presented under generally accepted accounting principles in the United States (“GAAP”), we believe certain non-GAAP measures, including adjusted net loss, and adjusted net loss per share, basic and diluted, provide useful information to investors and are useful in evaluating our operating performance. For example, we exclude stock-based compensation expense and loss on extinguishment of debt because these expenses are non-cash in nature and we believe excluding these items provides meaningful supplemental information regarding our operational performance and allows investors the ability to make more meaningful comparisons between our operating results and those of other companies.

We believe that non-GAAP financial information, when taken collectively, may be helpful to investors because it provides consistency and comparability with past financial performance. However, non-GAAP financial information is presented for supplemental informational purposes only, has limitations as an analytical tool and should not be considered in isolation or as a substitute for financial information presented in accordance with GAAP. In addition, other companies, including companies in our industry, may calculate similarly titled non-GAAP measures differently or may use other measures to evaluate their performance. A reconciliation is provided below for each non-GAAP financial measure to the most directly comparable financial measure stated in accordance with GAAP. Investors are encouraged to review the related GAAP financial measures and the reconciliation of these non-GAAP financial measures to their most directly comparable GAAP financial measures, and not to rely on any single financial measure to evaluate our business.

Adjusted Net Loss and Adjusted Net Loss Per Share

Adjusted net loss is a non-GAAP financial measure that we define as net loss adjusted for (i) stock-based compensation and (ii) loss on extinguishment of term loan. We believe adjusted net loss provides investors with useful information on period-to-period performance as evaluated by management and comparison with our past financial performance and is useful in evaluating our operating performance compared to that of other companies in our industry, as this metric generally eliminates the effects of certain items that may vary from company to company for reasons unrelated to overall operating performance.

Reconciliations of net loss to adjusted net loss and the presentation of adjusted net loss per share, basic and diluted, are as follows:
