Properties, in its own words
Our corporate headquarters is currently located in Billerica, Massachusetts, which consists of an approximately 91,600 square foot facility we lease for office and manufacturing purposes. We also lease office and laboratory space domestically in Bedford and Marlborough, Massachusetts and Georgetown, Texas, and internationally in the Netherlands, Sweden, and China. We do not currently occupy one of our Bedford facilities or two of the facilities acquired from Akoya (in Menlo Park, California and Marlborough, Massachusetts) and currently sublease a portion of these facilities.
We believe our facilities are adequate and suitable for our current operations and that, should it be needed, additional or alternative space is available to accommodate our operations.

Risk factors and legal proceedings
The risks Quanterix (United States) names in Item 1A of its 10-K filed Mar 2, 2026: 44 risks under these headings, as written.6
- Risks Related to our Financial Condition and Financial Reporting Matters
- Our quarterly and annual operating results and cash flows have fluctuated in the past, and our operating results may continue to fluctuate, which could cause the value of our common stock to fluctuate or decline significantly.
- We have incurred annual losses since our formation, and we expect to incur losses in the future. We cannot be certain that we will achieve or sustain profitability.
- Inherent limitations associated with, our internal control over financial reporting could result in material misstatements in our financial statements.
- Our ability to use net operating losses to offset future income may be subject to certain limitations.
- Risks Related to our Business
- Combining the businesses of Quanterix and Akoya may be more difficult, costly or time-consuming than expected and we may fail to realize the anticipated benefits of the acquisition, which may adversely affect our business results and negatively affect the value of our common stock.
- We may fail to achieve the remaining expected cost savings and related benefits from our cost reduction actions, and the consequences of those actions may adversely impact our business.
- Recent transitions in our board of directors and management could result in changes in our strategic plan, product focus, and investment priorities, and we might not realize the anticipated benefits from any such changes.
- If our products fail to achieve and sustain sufficient market acceptance, our revenue will be adversely affected.
- Sales of our Simoa-based assays for neurological indications have become increasingly important to our business, and there can be no assurance that we will be able to continue to generate meaningful revenues from the sale of such products.
- We may not be successful in penetrating the diagnostics market.
The other 34 risks
- The sales cycle for our instruments can be lengthy and variable, which makes it difficult for us to forecast revenue and other operating results.
- Purchase of our instruments by our customers requires a significant capital investment which can impact sales in times of constrained spending.
- Because a significant portion of our revenue comes from a few large customers, any significant decrease in sales to these customers, due to industry consolidation or otherwise, could harm our operating results.
- Our long-term results depend upon our ability to improve existing products and introduce and market new products successfully and timely.
- We may experience delays in launching and commercializing our next-generation instruments, on our anticipated timeline, which could adversely affect our business, financial condition, and results of operations.
- Defects or other quality issues in our products could lead to unforeseen costs, product recalls, adverse regulatory actions, negative publicity, and litigation, including product liability claims, any of which could cause customers to decide not to purchase our products, harm our reputation, and negatively affect our sales, operating results and financial condition.
- Our reliance on distributors for sales of our products outside of the United States could impact our revenue.
- We generate a substantial portion of our revenue internationally and we expect this will continue in the future; as a result, our business is subject to various risks relating to our international activities, which could adversely affect our business, operating results and financial condition.
- We rely on single contract manufacturers for several of our key instruments, and we expect to that to continue in the future. If any of these manufacturers should fail to perform, or not perform satisfactorily, our ability to supply these instruments would be negatively and adversely affected, which could have a material adverse effect on our business, financial condition, results of operations and reputation.
- We rely on a limited number of suppliers or, in some cases, one supplier, for some of our materials and components used in our consumable products and services and certain of our instruments, and we may not be able to find replacements or immediately transition to alternative suppliers if any of these suppliers fail to perform, which could have a material adverse effect on our business, financial condition, results of operations and reputation.
- We could be adversely affected by violations of the U.S. Foreign Corrupt Practices Act and other worldwide anti-bribery laws by us or our agents.
- The life sciences research and diagnostic markets are highly competitive. If we fail to effectively compete, our business, financial condition and operating results will suffer.
- Integrating any business, product or technology we acquire can be expensive and time-consuming and can disrupt and adversely affect our ongoing business, including product sales, and distract our management.
- Risks Related to Government Regulation and Diagnostic Product Reimbursement
- Changes in U.S. government policies, including reductions in federal research funding and the impacts of tariffs, are adversely affecting our business, though the full extent of the impact is uncertain. Similarly, there is substantial uncertainty regarding how the current administration’s initiatives might impact the FDA, its implementations of laws, regulations, policies and guidance and its personnel, which could prevent, limit or delay development and regulatory approval of our future diagnostic products.
- If the FDA determines that our products are subject to regulation as medical devices, if Congress enacts new laws that subject our LDT to FDA regulation, if we seek to market our products for clinical diagnostic or health screening use, or if we continue to expand our product, technology and service offerings and the applications and uses of our products into new fields, we expect to become subject to additional government regulations, and the regulatory approval and maintenance process would be expensive, time-consuming and uncertain both in timing and in outcome.
- Our products may in the future be subject to product recalls that could harm our reputation, business and financial results.
- U.S. legislative, FDA or global regulatory reforms may make it more difficult and costly for us to obtain any required regulatory approval of our product candidates and to manufacture, market and distribute our products after approval is obtained.
- If we do not comply with governmental regulations applicable to our CLIA-certified laboratory, we may not be able to continue our laboratory operations or continue offering our LDTs.
- We expect to rely on third parties in conducting any required future studies of diagnostic products that may be required by the FDA or other regulatory authorities, and those third parties may not perform satisfactorily.
- If diagnostic procedures that are enabled by our technology are subject to unfavorable pricing regulations or third-party coverage and reimbursement policies, our business could be harmed.
- Risks Related to our Operations
- We depend on our information technology systems, and any failure of these systems could harm our business.
- Cybersecurity breaches, loss of data and other disruptions could compromise sensitive information related to our business or prevent us from accessing critical information and expose us to liability, which could adversely affect our business and our reputation.
- We are currently subject to, and may in the future become subject to additional, U.S. federal and state and international laws and regulations imposing obligations on how we collect, store and process personal information. Our actual or perceived failure to comply with such obligations could harm our business. Ensuring compliance with such laws could also impair our efforts to maintain and expand our future customer base, and thereby decrease our revenue.
- Risks Related to Intellectual Property
- Inability to adapt to and effectively incorporate potential advantages of artificial intelligence (“AI”) could negatively impact our ability to compete, and inability to manage the risks of AI could expose us to liability or put us at a disadvantage.
- If we are unable to protect our intellectual property, our ability to maintain any technological or competitive advantage over our competitors and potential competitors may be reduced, and our business may be harmed.
- Some of our owned and in-licensed intellectual property has been discovered through government-funded programs and thus is subject to federal regulations such as “march-in” rights, certain reporting requirements, and a preference for U.S. industry. Compliance with such regulations may limit our exclusive rights, subject us to expenditure of resources with respect to reporting requirements, and limit our ability to contract with non-U.S. manufacturers.
- Our rights to develop and commercialize our products and technologies are subject, in part, to the terms and conditions of licenses granted to us by others.
- If we or any of our partners are sued for infringing intellectual property rights of third parties, the resulting litigation would be costly and time-consuming, and an unfavorable outcome in that litigation could have a material adverse effect on our business.
- We may be involved in lawsuits to protect or enforce our patents or the patents of our licensors, which could be expensive, time- consuming and unsuccessful.
- We may not be able to protect our intellectual property rights throughout the world, which could have a material adverse effect on our business.
- We use third-party software that may be difficult to replace or may cause errors or failures of our products that could lead to lost customers or harm to our reputation. Additionally, our use of “open source” software could adversely affect our ability to offer our products and technologies and subject us to possible litigation.
- Risks Related to our Common Stock and Being a Public Company
- The market price of our common stock has fluctuated significantly and may continue to fluctuate significantly.
- We have never paid dividends on our capital stock, and we do not anticipate paying any dividends in the foreseeable future. Consequently, any gains from an investment in our common stock will likely depend on whether the price of our common stock increases.
- Anti-takeover provisions contained in our restated certificate of incorporation and restated by-laws, as well as provisions of Delaware law, could impair a takeover attempt.
Legal proceedings
In the ordinary course of business, we are from time to time involved in lawsuits, claims, investigations, proceedings, and threats of litigation consisting of intellectual property, contractual, employment, and other matters. While the outcome of any such actions or proceedings cannot be predicted with certainty, as of the date of this Annual Report on Form 10-K, we were not party to any legal proceedings, the outcome of which would be expected to have a material adverse effect on our financial condition or results of operations. Regardless of any outcome, litigation can have a material adverse effect on us due to defense and settlement costs, diversion of management resources, and other factors.
