Management Commentary

"We are extremely proud of our achievements in 2023 and our team’s remarkable resilience, focus, and determination throughout a challenging LCD process in the back half of the year that ultimately resulted in the LCDs being withdrawn. We added highly experienced medtech growth leadership to our team, restructured our commercial organization for both increased efficiency and effectiveness, and meaningfully reduced our cash burn during a transient period of uncertainty, which I believe will lead to predictable long-term results as we enter our next exciting phase of transformative growth,” said Paul Badawi, co-founder and Chief Executive Officer of Sight Sciences.

“We believe we have multiple catalysts to be excited about in 2024. We plan to expand the library of clinical data demonstrating the differentiated safety and efficacy profiles of our interventional glaucoma and dry eye technologies, make significant progress towards meaningful reimbursement for TearCare, and based on the productive start to the year we expect to return to double-digit revenue growth in the second half of 2024 with our elevated commercial infrastructure and strategy,” continued Mr. Badawi.

Fourth Quarter 2023 Financial Results
Revenue for the fourth quarter of 2023 was $18.8 million, a decrease of $1.8 million, or 9%, compared to the same period in the prior year. Surgical Glaucoma revenue was $17.2 million, a decrease of 9% compared to the same period in the prior year. While customer retention was solid, the uncertainty resulting from the LCDs, which have now been withdrawn, was the primary driver of lower utilization and new account additions in the fourth quarter of 2023 versus the same period in the prior year. Dry Eye revenue was $1.6 million, a decrease of 11% from the same period in the prior year. The decline was primarily due to the evolution of the Company’s commercialization strategy for its Dry Eye segment, which emphasizes driving higher utilization within existing accounts to cultivate long-term recurring revenue, and the reduced sales infrastructure implemented as a result of the Company’s reorganization and cost-reduction measures taken in October 2023.

Gross profit for the fourth quarter of 2023 was $16.0 million compared to $16.9 million in the same period in the prior year. Gross margin for the fourth quarter of 2023 was 85%, compared to 82% in the same period in the prior year. The increase in gross margin was primarily driven by a prior year inventory charge for legacy components in the Company’s Surgical Glaucoma segment and continued manufacturing efficiencies compared to the prior year, partially offset by product sales mix. Surgical Glaucoma gross margin in the fourth quarter of 2023 increased to 88%, compared to 84% in the same period in the prior year, primarily driven by the prior year inventory charge described above and manufacturing efficiencies compared to the prior year, partially offset by production variances and lower ASPs due to product sales mix. Dry Eye gross margin in the fourth quarter of 2023 declined to 53%, compared to 59% in the same period in the prior year, primarily due to inventory reserve charges in the current period, partially offset by manufacturing efficiencies compared to the prior year.

Total operating expenses were $27.1 million in the fourth quarter of 2023 representing a 20% decrease compared to $33.9 million in the same period in the prior year, which reflects reduced research and development operating expenses and selling, general, and administrative operating expenses in the comparative periods, and improved operating expense leverage. Research and development expenses were $3.4 million in the fourth quarter of 2023 compared to $5.2 million in the same period in the prior year, representing a 35% decrease in the comparative periods. Selling, general, and administrative expenses were $23.7 million in the fourth quarter of 2023, compared to $28.7 million in the same period in the prior year, representing an 18% decrease in the comparative periods. Adjusted operating expenses^1,2 were $22.3 million in the fourth quarter of 2023, down from $30.6 million in the same period in the prior year.

Net loss was $10.7 million ($0.22 per share) in the fourth quarter of 2023, compared to $16.9 million ($0.35 per share) in the same period in the prior year.

Cash and cash equivalents totaled $138.1 million and total long-term debt was $35.0 million (before debt discount and amortized debt issuance costs) as of December 31, 2023, compared to $144.5 million and $35.0 million respectively as of September 30, 2023. Cash used in the quarter totaled $6.4 million, reflecting continued operational discipline and a sequential improvement from $10.0 million cash used in the third quarter of 2023 and a decrease versus the comparative period in the prior year where cash used in the fourth quarter of 2022 was $14.8 million.

Full Year 2023 Financial Results
Revenue for full year 2023 was $81.1 million, an increase of $9.7 million, or 14%, compared to full year 2022. Surgical Glaucoma revenue was $74.3 million, an increase of 13% compared to the prior year, and Dry Eye revenue was $6.7 million, an increase of 18% compared to the prior year.

Gross profit for full year 2023 was $69.2 million, compared to $59.0 million in 2022. Gross margin for the full year 2023 was 85%, compared to 83% in the prior year. Gross margin improvement was primarily attributable to manufacturing cost reductions and higher production volumes covering largely fixed allocated manufacturing overhead.

Total operating expenses were $126.4 million in 2023, representing a 12% decrease compared to $142.9 million in 2022, reflecting reduced research and development operating expenses and selling, general, and administrative operating expenses in the comparative periods, and improved operating expense leverage. Adjusted operating expenses^1,2 were $110.3 million for full year 2023, down from $128.5 million in the prior year.

Net loss was $55.5 million ($1.14 per share) for full year 2023, as compared to $86.2 million ($1.80 per share) in 2022.

Cash and cash equivalents totaled $138.1 million and total long-term debt was $35.0 million (before debt discount and amortized debt issuance costs) as of December 31, 2023, compared to $185.0 million and $35.0 million as of December 31, 2022. Cash used in full year 2023 totaled $46.9 million, reflecting continued operational discipline and an improvement from $75.7 million cash used in 2022.

Subsequent to year end, the Company announced the closing of a new senior secured credit facility of up to $65.0 million. The Company drew an initial $35.0 million from the facility to refinance its existing senior credit facility while maintaining its current debt outstanding. The new facility provides the Company the ability to draw up to an additional $30.0 million, subject to the satisfaction of certain conditions.
       
2024 Financial Guidance
Sight Sciences projects revenue for full year 2024 to range from approximately $81.0 million to $85.0 million, representing a range of 0% to 5% growth compared to 2023. The Company expects double-digit revenue growth in the second half of 2024 versus the comparable periods in the prior year as it regains commercial momentum and expands utilization and its customer base.

The Company expects full year 2024 adjusted operating expenses^1,3 of approximately $107.0 million to $110.0 million, representing a range of 0% to 3% decline compared to 2023, with higher first quarter adjusted operating expenses expected primarily due to higher legal expenses for pending litigation.

The Company's full year 2024 financial guidance is forward-looking in nature, reflecting our expectations as of March 7, 2024, and is subject to significant risks and uncertainties that limit our ability to accurately forecast results. This outlook assumes no meaningful changes to the Company's business prospects or risks and uncertainties identified by management that could impact future results, which include, but are not limited to: changes in the reimbursement environment, including coverage decisions and reimbursement rates; the outcome of clinical trials; the outcome of legal proceedings or regulatory matters; changes in economic conditions, including discretionary spending and inflationary pressures; and supply chain disruptions, constraints and related expenses.

¹ “Adjusted operating expenses” is a financial measure not prepared in accordance with the generally accepted accounting principles in the United States (“GAAP,” and such measure, a “non-GAAP financial measure”), and is calculated as operating expenses less stock-based compensation expense, depreciation and amortization, and restructuring costs. Please see the “Non-GAAP Financial Measures” section below for additional information.
² A reconciliation of the GAAP financial measures to the most directly comparable non-GAAP financial measures has been provided in the table titled "GAAP to Non-GAAP Reconciliation" attached to this press release.
³ Consistent with Securities and Exchange Commission regulations, the Company has not provided a reconciliation of forward-looking non-GAAP financial measures to the most directly comparable GAAP financial measures in reliance on the “unreasonable efforts” exception set forth in the applicable regulations, because there is substantial uncertainty associated with predicting any future adjustments that may be made to the Company’s  GAAP financial measures in calculating the non-GAAP financial measures.

Non-GAAP Financial Measures
Certain non-GAAP financial measures, including adjusted operating expenses are presented in this press release to provide information that may assist investors in understanding the Company's financial and operating results. The Company believes these non-GAAP financial measures are important performance indicators because they exclude items that are unrelated to, and may not be indicative of, the Company's core financial and operating results. These non-GAAP financial measures, as calculated, may not necessarily be comparable to similarly titled measures of other companies and may not be appropriate measures for comparing the performance of other companies relative to the Company. These non-GAAP financial measures are not intended to represent, and should not be considered to be more meaningful measures than, or alternatives to, measures of operating performance as determined in accordance with GAAP. To the extent the Company utilizes such non-GAAP financial measures in the future, it expects to calculate them using a consistent method from period to period.
