What Sight Sciences, Inc. told the SEC could break it.
Sight Sciences' disclosures concentrate on a single-source, China-based supply chain. Substantially all of its revenue-generating products — OMNI, SION, and TearCare SmartLids — are produced and assembled by one Taiwan-based manufacturer in China, with many components from single-source suppliers and no internal manufacturing capability. That China concentration directly exposes it to U.S. tariffs, which hurt 2025 gross margins and could worsen if trade tensions escalate (it is shifting some production out of China in 2026). Its balance sheet adds leverage risk: the Hercules term loan is secured by a lien on substantially all assets and carries financial covenants, with $5.1 million of interest expense in 2025 for this pre-profit company.
3 self-disclosed vulnerabilities, pulled from its own filings, each in the company’s words, with the source. This is the risk register almost nobody reads.
In its own words
What could break it.
Sole-source dependency
- single Taiwan-based manufacturer in China (substantially all products)high
Substantially all revenue-generating products (OMNI, SION, TearCare SmartLids) are produced and assembled by a single Taiwan-based manufacturer in China, with many components from single-source suppliers and no internal manufacturing capability.
“Specifically, most of our OMNI and SION products, as well as our TearCare SmartLids, are currently produced and assembled by a single Taiwan-based manufacturer in China. These commercial products comprise substantially all of our current revenue.”
Liquidity & debt
- Hercules secured term loan (all-asset collateral, covenants)medium
The Company's Hercules Loan Agreement is secured by a lien on substantially all assets and carries financial covenants and warrant obligations; interest expense was $5.1 million in 2025 for this pre-profit medical-device company.
“Our obligations under the Hercules Loan Agreement are collateralized by a security interest in substantially all of our assets. The Hercules Loan Agreement contains customary representations and warranties, affirmative covenants, negative covenants, financial covenants, events of default and other provisions and conditions.”
SEC filing →As of 2026
Regulatory & policy
- U.S. tariffs on China importsmedium
Because the vast majority of products are manufactured in China, U.S. tariffs on Chinese imports negatively impacted 2025 gross margins and could worsen if trade disputes escalate; the company is shifting some production out of China in 2026.
“The United States tariffs on imports from China had a negative impact on our gross margins in 2025, as the vast majority of our products were manufactured by third parties with manufacturing facilities located in China.”
