Exhibit 1.01

Corning Incorporated
Conflict Minerals Report
For the Year Ended December 31, 2025

This Conflict Minerals Report (CMR) for the year ended December 31, 2025 is presented to comply with Rule 13p-1 under the Securities Exchange Act of 1934 (the Rule). The Rule was adopted by the Securities and Exchange Commission (SEC) to implement reporting and disclosure requirements related to conflict minerals as directed by the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 (Dodd-Frank Act). The Rule imposes certain reporting obligations on SEC registrants whose manufactured products contain conflict minerals which are necessary to the functionality or production of their products. Conflict Minerals are defined as cassiterite, columbite-tantalite, gold, wolframite, and their derivatives, which are limited to tin, tantalum, tungsten, and gold (3TG).

This report is available on the Investor Relations page of Corning’s website (see http://www.corning.com/investor_relations/index.aspx and click on “Financials and Filings”).

This report has been prepared by management of Corning Incorporated (herein referred to as “Corning,” the “Company,” “we,” “us,” or “our”). The information includes the activities of all majority-owned subsidiaries and variable interest entities that are required to be consolidated in accordance with US Generally Accepted Accounting Principles. It does not include the activities of subsidiaries or variable interest entities that are not required to be consolidated.

Corning is a world leader in the manufacture of specialty glass and ceramics. Drawing on 175 years of materials science and process engineering knowledge, Corning creates and makes keystone components that enable high-technology systems for consumer electronics, mobile emissions control, telecommunications and life sciences. Corning manufactures products in 14 countries and operates in four reportable segments: Optical Communications, Glass Innovations, Automotive, and Solar. All other businesses that do not meet the quantitative threshold for separate reporting have been grouped as Life Sciences and Emerging Growth Businesses.

Corning’s principal products, by segment, are as follows:

Optical Communications – manufactures carrier network and enterprise network components for the telecommunications industry; the carrier network group consists primarily of products and solutions for optical-based communications infrastructure for services such as video, data and voice communications; the enterprise network group consists primarily of optical-based communication networks, including hyperscale data centers, sold to businesses, governments and individuals for their own use.

Glass Innovations – utilizes proprietary melting, precision forming, strengthening, and finishing processes to create advanced flat glass substrates for LCD and OLED displays and cover materials for mobile consumer electronics; and provides material formulations and optical fabrication for specialty glass, glass ceramic, fluoride crystal, and other precision materials and components for semiconductor, aerospace and defense, telecommunications, commercial, and industrial applications.

Solar – manufactures silicon materials and products for semiconductor and solar applications, including hyper-pure polysilicon produced by Hemlock Semiconductor Group, solar wafers, and solar modules. The segment’s products serve customers across the semiconductor and solar markets globally from a manufacturing footprint in the United States.

All other businesses that do not meet the quantitative threshold for separate reporting have been grouped as Life Sciences and Emerging Growth Businesses.

Corning maintains complex and diverse supply chains across its reported segments, involving thousands of suppliers to the Company. We rely on our direct suppliers to provide information on the origin of the 3TG contained in components and materials supplied to us – including sources of 3TG that are supplied to them from lower-tier suppliers. Contracts with our suppliers are frequently in force for three years or more and we cannot unilaterally impose new contract terms and flow-down requirements. Corning has incorporated a clause into relevant agreements that requires suppliers to provide information about the source of conflict minerals and the location of smelters. Based upon these contractual requirements and our supplier relationships, we work annually with selected suppliers to ensure they provide us the 3TG sourcing information required.

Based upon technical knowledge regarding our products, as well as the results of the prior supplier surveys regarding conflict minerals, relevant personnel in each of our reported segments identified the suppliers to survey regarding whether the components or materials supplied to Corning by such suppliers contain 3TG. We relied upon these suppliers, 205 in total, to provide us with information about whether the components or materials supplied to Corning contain 3TG; and, if so, the source of such 3TG. Our direct suppliers are similarly reliant upon information provided by their suppliers, or in the case of distributors from whom we purchase components or materials, reliant upon the manufacturers of such items. Many of our larger suppliers are also SEC registrants and subject to the Rule.

We surveyed those suppliers described above using the latest version 6.5 or version 6.4 of the Responsible Minerals Initiative (“RMI”) Conflict Minerals Reporting Template (“CMRT”), an industry-standard template used to facilitate the collection of information regarding the smelters and refiners in a company’s supply chain. It includes questions regarding a company’s conflict-free policy, engagement with its direct suppliers, and a listing of the smelters the company and its suppliers use. In addition, the CMRT contains questions about the origin of conflict minerals included in their products, as well as supplier due diligence. Written instructions and recorded training illustrating the use of the tool are available on the RMI’s website. The CMRT is being used by many companies in their due diligence processes related to 3TG.

To determine whether any 3TG necessary to our products originated in the Covered Countries, we retained a third-party service provider, Assent Compliance (“Assent”) to assist us in surveying our supply chain. During our supplier survey, we contacted suppliers via the Assent Compliance Manager (“ACM”), a SaaS platform provided by Assent that enables its users to complete and track supplier communications and allows suppliers to upload completed CMRTs directly to the platform for assessment and management. The use of the CMRT allowed for some elimination of irrelevant suppliers. Specifically, question one of the CMRT asks suppliers whether any 3TGs are necessary to the functionality or production of their products. We also reviewed the supplier list to ensure that irrelevant or “out of scope” suppliers were removed from the survey process (e.g., the removal of suppliers who provided only packaging to Corning).

Assent requested that all in-scope suppliers complete a CMRT and included training and education to guide suppliers on best practices and the use of the template. Assent monitored and tracked all communications in the ACM for future reporting and transparency. Corning directly contacted suppliers that were unresponsive to Assent’s communications during the diligence process and requested that such suppliers complete and submit the CMRT to Assent.

Where the CMRT responses included the names of entities listed by our suppliers as smelters or refiners, Assent consulted the RMI publicly available information to determine whether such entities had been identified as certified Conflict-Free. In some cases, the CMRT responses did not provide smelter information; this was one of the items that we typically requested in follow-up communications with suppliers. Ultimately, some suppliers were unable to provide us with smelter information because they were engaged in their own efforts to obtain that information from their suppliers.

Through Assent’s platform, automated data validation was performed on all submitted CMRTs. The goal of data validation is to increase the accuracy of submissions and identify any contradictory answers in the CMRT. This data validation is based on logical sequencing and required correlations between the CMRT questions (for example, if a supplier does not report having received information from 100% of its 3TG sources, it cannot logically offer definitive statements in response to certain other questions).

All submitted CMRTs are first accepted and then classified as valid or invalid so that their data is still retained. Suppliers are contacted in regard to invalid forms and are encouraged to resubmit a valid form. As of May 8, 2026, there were seven (7) invalid supplier submissions in Corning’s supplier survey that could not be corrected.

Many of the responses we received provided data at a company or divisional level or, as described above, were unable to specify with certainty all of the smelters or refiners used for components supplied to Corning. In some instances, we engaged in follow-up communications with suppliers to request that they provide a CMRT response specific to the components or materials supplied to Corning; however, in many cases, the suppliers were unable to do so because they were unable to obtain detailed information from their own suppliers.

Our RCOI determined that certain of the 3TG contained in the products sold by Corning may have originated in the Covered Countries. Thus, we are required under the Rule to conduct due diligence on the source and chain of custody of those minerals and submit to the SEC a Conflict Minerals Report as an Exhibit to Form SD.

Our due diligence measures have been designed to conform, in all material respects, with the framework in The Organization for Economic Co-operation and Development (OECD) Due Diligence Guidance for Responsible Supply Chains of Minerals from Conflict-Affected and High-Risk Areas, Third Edition, 2016 (OECD Guidance) and the related Supplements for gold and for tin, tantalum and tungsten. The Guidance identifies five steps for due diligence that should be implemented and provides guidance as to how to achieve each step. We developed our due diligence process to address each of these five steps, namely:

We are mostly a downstream supplier, many steps removed from the mining of 3TGs. A large number of suppliers, through multiple tiers of distribution, supply the components and materials integrated into our products. Furthermore, we do not purchase raw ore or unrefined conflict minerals directly. The origin of the conflict minerals cannot be determined with any certainty once the raw ores are smelted, refined and converted to ingots, bullion or other conflict mineral containing derivatives. The smelters and refiners consolidate raw ore and represent the best actors in the total supply chain to possess knowledge of the origin of the ores they procure.

We have adopted the following Corporate Position on Conflict Minerals, effective February 2022:

Corning Incorporated’s Corporate Position on Conflict Minerals

At Corning, corporate social responsibility is a proactive commitment to preserving the trust of our stakeholders. This commitment contributes to sustainable economic and environmental development through all our business activities – how we operate, what we sell, how we give, and how we support our people, the communities in which we operate, and society at large. It is also a demonstration of how we live our Values (see https://www.corning.com/worldwide/en/sustainability/people/values.html) which represent the unchanging moral and ethical compass that guides everything we do.

As part of our commitment to corporate social responsibility, Corning is committed to the responsible sourcing of minerals – sourcing done in an ethical and sustainable manner that safeguards the human rights of everyone in our global supply chain and preserves the environment. Any connection between the materials used in Corning products and armed violence or human rights abuses is unacceptable.

Corning requires our suppliers to comply with our requests to provide complete and accurate information about minerals supplied to Corning, and to perform further due diligence as required about the source of any minerals in their products which are provided to us in order to ensure alignment throughout the supply chain. Failure to provide this information to Corning when requested may result in removal from active status as a Corning supplier.

We also require our suppliers to extend these expectations to their own suppliers. Suppliers are required to include provisions equivalent to Corning’s Supplier Code of Conduct, which include a commitment to responsible minerals sourcing and prohibition of forced labor, in their supply chain agreements and to flowdown the same requirements throughout their supply chains. See our Supplier Code of Conduct at https://www.corning.com/worldwide/en/sustainability/processes/supply-chain-social-responsibility/supplier-responsibility/supplier-code-of-conduct.html.

Conflict Minerals

The term “conflict minerals” refers to the mineral precursors of the metals tantalum, tin, tungsten, and gold (also known as “3TG”), which are found in small amounts in virtually all electronic products. Revenue from mining these minerals in the Democratic Republic of Congo (DRC) and nine neighboring countries has been linked to funding for groups engaged in extreme violence and human rights atrocities.

Pursuant to the Dodd–Frank Wall Street Reform and Consumer Protection Act, public companies in the US that make products for which 3TG metals are necessary to the functionality or production of those products are required to assess their supply chains and report on the source of these materials. Corning is a public company, and therefore is committed to complying with this law.

Corning’s Position on Conflict Minerals

The 3TG supply chain is complex, typically including many stages between Corning and the smelters that purchase and process the ore into metals. The greatest risk of conflict minerals entering our supply chain is through these smelters’ ore purchasing practices.

We require our suppliers to source 3TG for Corning products only from smelters that comply with the Responsible Minerals Initiative ’s (RMI, formerly the Conflict Free Sourcing Initiative) Responsible Minerals Assurance Process (RMAP, formerly the Conflict-Free Smelter Program), which requires a third-party sourcing audit. To monitor 3TG suppliers’ performance, we assess their responses to the RMI’s Conflict Minerals Reporting Template, and request corrective action where needed, including the removal from our supply chain of smelters that pose a risk. More information about the Responsible Minerals Initiative can be found at https://www.responsiblemineralsinitiative.org/. Our due diligence measures implemented as part of our conflict minerals program have been designed to conform, in all material respects, with the framework in The Organization for Economic Co-operation and Development (OECD) Due Diligence Guidance for Responsible Supply Chains of Minerals from Conflict-Affected and High-Risk Areas.

Our policy is publicly available on our website at the following link:

https://www.corning.com/media/worldwide/global/documents/Responsible%20Minerals%20Policy.pdf

Corning has established a cross-functional Conflict Minerals Compliance Team for managing our conflict minerals program. This core team, which includes subject matter experts from relevant functions such as legal, strategic sourcing and global supply management sustainability, is responsible for implementing our conflict minerals compliance strategy. Senior management is briefed about the results of our due diligence efforts on an annual basis. Corning also uses a third-party service provider, Assent, to assist us with evaluating supply chain information regarding 3TGs, identifying potential risks, and in the development and implementation of additional due diligence steps that we will undertake with suppliers regarding conflict minerals.

Corning leverages Assent’s Managed Services in order to work with dedicated program specialists who support Corning’s conflict minerals program. Corning communicates regularly with the Assent team in order to receive updates on program status. Each member of Assent’s Customer Success team is trained in conflict minerals compliance and understands the intricacies of the CMRT and conflict minerals reporting, as well as Section 1502 of the Dodd-Frank Act.

As we do not typically have a direct relationship with 3TG smelters and refiners, we have relied upon industry-wide initiatives to disclose upstream actors in the supply chain. Specifically, as part of our due diligence efforts, we have utilized the smelter information provided by the Responsible Minerals Initiative.

In addition, Corning maintains internal control processes, supported by cross-functional coordination with legal, strategic sourcing and global supply management sustainability, to oversee and monitor its conflict minerals due diligence program.

With respect to the OECD requirement to strengthen engagement with suppliers, we have added a conflict minerals clause to our purchase order terms and conditions and relevant contract templates in order to communicate to suppliers our expectations and requirements regarding the sourcing of and disclosure of conflict minerals. We also include our Supplier Code of Conduct in our supplier contracts, which contains Corning’s expectations for suppliers with respect to humane labor conditions, health and safety, and environmental factors, among others. Further, Corning’s suppliers are required to flow down these expectations from Corning’s Supplier Code of Conduct to their own supply chains.

A copy of our Supplier Code of Conduct is available at https://www.corning.com/worldwide/en/sustainability/processes/supply-chain-social- responsibility/supplier-responsibility/supplier-code-of-conduct.html

Corning’s Supplier Code of Conduct, referenced in 5.2.4 above, instructs suppliers that questions or concerns may be submitted to Corning’s third-party telephone and web hotline service. This hotline is also described in Corning’s Code of Conduct, as referenced above. These phone or web services can be used to make an anonymous report and are available on a 24/7 basis. Corning maintains a robust internal compliance and ethics program under the oversight of a Vice President and Chief Compliance Officer to ensure that all such reports are properly investigated, reported and remediated as required.

Violations or grievances at the industry level can be reported to the RMI directly as well. This can be done at https://www.responsiblemineralsinitiative.org/rmap/grievance-mechanism/

Corning has an existing document retention policy which governs the retention of documentation relevant to our due diligence efforts. We also implemented a document retention policy through Assent to retain conflict minerals related documents, including supplier responses to CMRTs. Assent stores the information and findings from this process in a database that can be audited by internal or external parties.

Because of our size, the complexity of our products, and the depth and breadth of our supply chain, it is difficult to identify actors upstream from our direct suppliers. One method for identifying risks in our supply chain is through automatic checks in the ACM system based on criteria established by Assent for supplier responses as outlined above.

In accordance with OECD Guidelines, it is important to understand risk levels associated with conflict minerals in the supply chain. Smelters or refiners not being certified DRC-Conflict Free pose a significant risk to the supply chain. Certain of the responses provided by our suppliers via the CMRT included the names of facilities listed by the suppliers as smelters or refiners.  We do not typically have a direct relationship with 3TG smelters and refiners and do not perform or direct audits of these entities within our supply chain. Assent compared these facilities listed in the responses to the list of smelters and refiners maintained by the RMI and, if a supplier indicated that the facility was certified as “Conflict-Free,” confirmed that the name was listed by RMI. As of May 8, 2026, of the 338 legitimate smelter and refiners identified by our suppliers, we have validated 209 smelters or refiners as Responsible Minerals Assurance Process (“RMAP”) conformant. Due to the provision of a mix of company-level, product-level and user defined CMRTs, we cannot definitively determine the connection of any smelters or refiners listed in them to our in-scope products.

Each facility that meets the RMI definition of a smelter or refiner of a 3TG mineral is assessed according to red flag indicators defined in the OECD Guidance. Assent determines the level of risk that each smelter poses to the supply chain by identifying the following red flags:

Based on these criteria the following facilities have been identified as “high risk” smelters that may exist in Corning’s supply chain:

Notably, seventeen of the above facilities are in Russia. Effective in September 2022, RMI suspended new RMAP assessments in Russia, based on legal compliance requirements and risks associated with facilitating audits in Russia, as RMI explained in more detail at https://www.responsiblemineralsinitiative.org/news/notice-regarding-rmap-russia-based-auditees/. The suspension impacts inclusion of auditees in Russia on the public RMAP Conformant and Active lists. Thus, the inclusion of Russian facilities in the list above may not indicate concerns with their mineral sourcing practices.

As part of our risk management plan under the OECD Guidance, when these facilities were reported on a CMRT by one of the suppliers we surveyed, risk mitigation activities were initiated. Through our third-party vendor, Assent Compliance, submissions that included any of the above facilities immediately produced a receipt instructing the supplier to take their own risk mitigation actions, including submission of a product specific CMRT to better identify the connection to products that they supply to Corning, and escalating up to removal of these high-risk smelters from their supply chain.

As per the OECD Guidance, risk mitigation will depend on the supplier’s specific context. Suppliers may be given clear performance objectives within reasonable timeframes with the ultimate goal of progressive elimination of these red flags from the supply chain. Suppliers are guided to the Assent University learning platform to review educational materials on mitigating the risk of smelters or refiners on the supply chain.

Additionally, suppliers are evaluated on program strength (further assisting in identifying risk in the supply chain). Evaluating and tracking the strength of the program meets the OECD Due Diligence Guidelines and can assist in making key risk mitigation decisions as the program progresses. The criteria used to evaluate the strength of the program are based on these four questions in the CMRT:

A. Have you established a conflict minerals sourcing policy?

D. Have you implemented due diligence measures for conflict-free sourcing?

F. Do you review due diligence information received from your suppliers against your company’s expectations?

G. Does your review process include corrective action management?

When suppliers meet or exceed those criteria (Yes to at least A, D, F, G), they are deemed to have a strong program. When suppliers do not meet those criteria, they are deemed to have a weak program. At this time, sixty two percent (62%) of our 180 valid, responsive suppliers were identified as either having a strong program or no 3TGs.

Corning has developed processes to assess and respond to the risks identified in the supply chain. Corning has implemented a conflict minerals program that with the support of Assent manages and monitors conflict mineral related risk in our supply chain. As the program progresses, escalations are sent to non-responsive suppliers to outline the importance of a response via CMRTs and to outline the required cooperation for compliance to the conflict minerals rules and Corning’s expectations.

As described in our conflict minerals policy, we intend to engage with any of our suppliers which we have reason to believe are supplying us with 3TG from sources that may support conflict in the DRC or any adjoining country to appropriately address the situation, which may include establishing an alternative source of 3TG that does not support such conflict, as provided in the OECD guidance. The result and timing will depend upon factors such as the criticality of the specific part and the availability of alternate suppliers. The results of the program and risk assessment are shared with the Conflict Minerals Compliance Team and the leadership of Corning’s Global Supply Management function to ensure transparency within the company.

Corning does not perform direct audits of 3TG smelters or refiners within our supply chain. Thus, we rely on third-party audit programs, including RMAP and other RMI-compliant audit frameworks, as industry-accepted mechanisms for assessing smelter and refiner due diligence. The RMAP uses independent private-sector auditors, and audits the source, including the mines of origin, and the chain of custody of the conflict minerals used by smelters and refiners that agree to participate in the program.

In early 2020, Corning became a member of the Responsible Minerals Initiative, enabling us to expand our industry collaborative efforts through RMI membership and to utilize RMI’s flagship Responsible Minerals Assurance Process (“RMAP”) through our supply chain as described above.

Assent also directly contacts smelters and refiners that are not currently enrolled in the RMAP to encourage their participation and gather information regarding each facility’s sourcing practices on behalf of its compliance partners. Corning is a signatory of this communication in accordance with the requirements of downstream companies detailed in the OECD Guidance.

Through the company’s membership in the RMI, smelters or refiners have been encouraged to participate in the RMAP. Any smelters or refiners that were reported by suppliers who were not part of the RMAP were also contacted directly by Assent to encourage them to participate in the RMAP.

In addition to this report, see our website at http://www.corning.com/worldwide/en/about-us/suppliers.html for further information about Corning’s commercial relationships with and expectations of its suppliers.

Corning conducted a survey of its relevant suppliers (as described above) using the Responsible Minerals Initiative (“RMI”) Conflict Minerals Reporting Template (“CMRT”). The CMRT is an industry-standard template used to facilitate the collection and communication of information regarding smelters and refiners in a company’s supply chain. It includes questions regarding a company’s conflict-free policy, engagement with its direct suppliers, and a listing of the smelters the company and its suppliers use. In addition, the CMRT contains questions about the origin of conflict minerals included in suppliers’ products, as well as supplier due diligence. Written instructions and recorded training

illustrating the use of the tool are available on RMI’s website and via the website of Assent Compliance, our third-party provider.

Because a significant portion of supplier responses were provided at the company or divisional level rather than at the product level, many of the smelters, refiners, and countries disclosed in this report represent facilities reported by suppliers as potentially in scope for their broader operations and may not all be connected to the specific products supplied to Corning.

Corning surveyed 205 suppliers based upon the likelihood that such suppliers supplied materials or components to Corning that contained one or more 3TG, and we received responses from 187 of the suppliers we surveyed. A total of nineteen (19) suppliers indicated in their survey responses that they sourced 3TG from the Covered Countries, but those 3TG were “conflict free.” 53 of the suppliers surveyed stated that the 3TG they sourced came from outside of the Covered Countries, and 51 suppliers reported as “undeterminable” in regard to sourcing 3TGs from the Covered Countries. 57 suppliers indicated their materials did not contain 3TG, and 7 responses could not be validated.

We have determined that seeking information about 3TG smelters and refiners in our supply chain through the use of the CMRT with our relevant suppliers represents the most reasonable effort we are able to make to determine the mines or locations of origin of the 3TG in our supply chain.

Because of the incomplete information provided to us by our suppliers in response to our surveys, or the receipt of company-level responses that do not provide information specific to materials or components supplied to Corning, in many cases the smelters and refiners we have identified to date cannot be tied to specific Corning products. However, in certain instances, our suppliers did provide CMRTs specific to the products supplied to Corning. We have reported all legitimate smelter or refiner information included in the CMRTs we received on Appendix A to this report, recognizing as stated above that not all such smelters or refiners can definitively be tied to Corning products. Of the 338 legitimate smelters identified on the CMRTs we received, as of May 8, 2026, 209 were identified as RMAP Conformant and 9 were actively working toward a “conflict free” designation. As noted, our list of processing smelters and refiners disclosed in Appendix A may contain more facilities than those that processed the conflict minerals actually contained in our products.

Appendix B includes an aggregated list of the countries of origin from which the reported facilities collectively source conflict minerals, based on information provided by suppliers and the RMI. As mentioned in the above section, many responses were provided at the company level; therefore, Appendix B may contain more countries than those that the conflict minerals used in our products are sourced from.

We have taken and/or intend to continue to take the following steps to improve the due diligence conducted to further mitigate any risk that the necessary conflict minerals in our products could benefit armed groups in the DRC or adjoining countries:

Appendix A

RMI Smelter List¹

¹ This Exhibit contains all legitimate smelter or refiner information we received on the CMRTs provided by our suppliers in response to our survey requests. Because these CMRTs in some instances contained incomplete information, or were not specific to the products supplied to Corning, many of these smelters and refiners cannot be tied to specific Corning products.

Appendix B

Country of Origin Information

This list of potential countries of origin is populated based on publicly available information, our RCOI and due diligence. It is important to note that this is also based on company level responses and therefore, it is not certain which of these countries of origin can be specifically linked to our products.
