Note 1. The Company and Nature of Business

Description of Business

Sight Sciences, Inc. (the “Company”) was incorporated in the State of Delaware in 2010 and is headquartered in Menlo Park, California. The Company is an ophthalmic medical device company focused on the development and commercialization of surgical and nonsurgical technologies for the treatment of prevalent eye diseases. The Company’s mission is to develop transformative, interventional technologies that allow eyecare providers to procedurally elevate the standards of care — empowering people to keep seeing.

The Company's product portfolio aligns with its two reportable operating segments: Surgical Glaucoma and Dry Eye. The products for the Surgical Glaucoma segment include the OMNI® Surgical System ("OMNI"), which is an implant-free, handheld, single-use, therapeutic technology that enables ophthalmic surgeons to perform a comprehensive procedure (i) indicated in the United States to reduce intraocular pressure in adult patients with primary open-angle glaucoma, and (ii) CE Marked for the catheterization and transluminal viscodilation of Schlemm’s canal and cutting of the trabecular meshwork to reduce intraocular pressure in adult patients with open-angle glaucoma; and the SION® Surgical Instrument ("SION"), a bladeless, manually operated device used in ophthalmic surgical procedures to excise trabecular meshwork. The product portfolio for the Dry Eye segment consists of the TearCare® System ("TearCare") for ophthalmologists and optometrists. TearCare is a proprietary, interventional, dry eye device designed to melt and facilitate the comprehensive removal of meibomian gland obstructions and restore gland functionality and healthy oil production for adult patients with evaporative dry eye disease due to meibomian gland dysfunction (“MGD”) when used in conjunction with manual expression of the meibomian glands, enabling clearance of gland obstructions by physicians to address the leading cause of dry eye disease.

Liquidity Considerations

Since inception, the Company has incurred losses and negative cash flows from operations. As of December 31, 2024, the Company had an accumulated deficit of $346.3 million and recorded a net loss of $51.5 million for the year then ended and expects to incur additional losses in the future.

The Company believes its cash and cash equivalents balance, and other existing sources of liquidity will satisfy its working capital and capital resource requirements for at least 12 months from the date of issuance of its consolidated financial statements. Any failure to generate increased revenue, achieve improved gross margins, or control operating costs could require the Company to raise additional capital through equity or debt financing. Such additional financing may not be available on acceptable terms, or at all. If the Company is unable to improve its financial performance, or to secure additional funding when desired, it may need to delay the development of its products, reduce research and development activities, modify, or abandon planned future expenditures or reduce operating costs, any of which could harm its business, require it to change its business strategy or scale back its operations, or limit its ability to achieve its strategic objectives.
