2.Products Overview

During 2025, Teradata did not manufacture any of its hardware products. The equipment (excluding software) comprising Teradata's products typically includes electronic computer processors, boards, servers, data storage, power supplies, cabinetry, and related tangible components. Collectively, the tangible components of those products are referred to in this Report as Teradata "hardware" or Teradata "hardware products." Other products, including third-party equipment are outside the scope of this Report.

Teradata engineers, designs, and establishes specifications for Teradata hardware products, leveraging components from industry leaders and using industry-standard technologies selected and configured to work optimally with other hardware components and software. All Teradata hardware products distributed during 2025 were either produced by its electronics

manufacturing services provider, Flex Ltd. ("Contract-Manufacturer"), or by its new electronics provider, Dell Technologies ("Product Provider"). Teradata has determined that certain hardware products that were purchased from its Contract-Manufacturer and Product Provider in 2025 contain Necessary Conflict Minerals.

3.Supply Chain Overview

The Contract-Manufacturer manufactured and assembled Teradata's hardware products and initiated distribution of those products from the United States. The Product Provider purchased products from its contract manufacturers and sold those products to Teradata. Teradata's hardware products purchased from the Contract-Manufacturer and Product Provider include components and materials from multiple upstream suppliers, supplier-tiers and sources across the world. Teradata is multiple supplier-tiers downstream from the SORs that provide materials used in the supply chain for Teradata hardware components. Teradata has had no direct relationships with SORs, and has had no direct presence, direct business activities, or employees located in the Covered Countries.

5. Conflict Minerals Due Diligence

A.Conflict Minerals Policy

Teradata has designed its Conflict Minerals Policy (the "Policy") and associated due diligence processes to support and align with the RMI and RMAP frameworks and thereby with the five-step framework set forth in the Third Edition of the Organisation for Economic Co-operation and Development's "Due Diligence Guidance for Responsible Supply Chains of Minerals from Conflict-Affected and High-Risk Areas" and the supplements thereto (the "OECD Guidance").

The Policy , which is publicly available on its website, has been communicated to relevant personnel and is available to all Teradata employees via the website. Among other things, the Policy:

•authorizes and assigns responsibilities in relation to Conflict Minerals management;

•encourages respect and protection of human rights and the environment with its supply chain;

•fosters supply chain integrity, ethics, compliance and accountability, including with respect to Conflict Minerals, Conflict Minerals legal duties and Conflict Minerals industry and framework initiatives;

•prohibits the knowing use of Conflict Minerals that directly or indirectly finance or benefit armed groups;

•establishes an escalation and corrective actions process in the event of actual or suspected Conflict Minerals compliance risks, exceptions, or violations;

•adopted procedures that Teradata's Conflict Minerals initiatives and status are reviewed with Teradata senior management and, as needed, with the Audit Committee of Teradata's Board of Directors; and

•adopted procedures and expectations that the Policy is reviewed and updated on an as-required basis to assure that any new legal developments are accounted for on a timely basis.

Teradata has included compliance requirements in our Contract-Manufacturer and Product Provider contracts to comply with all applicable laws, orders, and regulations of any governmental authority for Teradata hardware products.

B.Supply Chain Risk Identification and Assessment

•Teradata has communicated with the Contract-Manufacturer and Product Provider regarding Conflict Minerals surveying, tracking, reporting, expectations, and upstream key supplier communications with respect to direct suppliers of components for hardware that contain any Necessary Conflict Minerals.

•Teradata has reviewed relevant websites, statements, Conflict Minerals Policies, and/or Conflict Minerals Reports of its Contract-Manufacturer and Product Provider SOR lists regarding their stated Conflict Minerals initiatives, processes, Reasonable Country of Origin Inquiry ("RCOI" - defined below) inquiry processes, and due diligence processes.

•Teradata has received and reviewed RMI Conflict Minerals Reporting Template ("CMRT") forms for 2025, completed by the Contract-Manufacturer and Product Provider.

•Teradata designed its Conflict Minerals program and actions and determinations related to the Conflict Minerals program described in this Report, in good faith, to meet Reasonable Country of Origin Inquiry ("RCOI" - defined below) requirements of the Rule and OECD Guidance.

•Teradata has, through its participation in and support of the RMI, helped make Conflict Minerals training, guidance, and resources available to its employees, suppliers, and others.

C.Conflict Minerals Analysis

Based upon a review of Teradata's product categories and the information it has received from the RMI CMRT, Teradata has concluded that (i) certain Teradata hardware products purchased during 2025 contain Necessary Conflict Minerals; and (ii) the Necessary Conflict Minerals included in Teradata hardware products may have originated from the Covered Countries and (iii) the Necessary Conflict Minerals included in Teradata hardware products did not originate exclusively from recycled or scrap resources.

Teradata also determined that its Contract-Manufacturer and Product Provider (i) have Conflict Minerals Policies for their suppliers, which is publicly available at www.flex.com and www.dell.com respectively; (ii) are members of the RMI and use the RMI CMRT in connection with their Conflict Minerals programs; and (iii) are subject to the Rule and have annually filed Form SDs and accompanying Conflict Minerals reports, which are available on the SEC website at www.sec.gov.

Based on information provided by our Contract-Manufacturer, during 2025, 51 suppliers, including the Contract-Manufacturer and its affiliates ("key suppliers"), directly provided hardware components and materials for Teradata hardware products. Of these suppliers 36 provided components and or materials that contain Necessary Conflict Minerals. It was determined that 15 of such suppliers solely provide components or materials that do not contain any Necessary Conflict Minerals or are outside the scope, such as components or materials that are solely plastic, non-metallic fasteners, aluminum, packaging, test media, documentation, ink or a label.

Our Product Provider did not share information on its suppliers or the proportion of suppliers that provide components or materials containing Necessary Conflict Minerals at the time of this report. As a result, Teradata's ability to fully assess upstream supply chain risks for products sourced from the Product Provider is limited. Throughout 2025 and into 2026, Teradata made multiple written requests to the Product Provider to obtain supplier-level Conflict Minerals data and RCOI engagement status; however, the Product Provider has indicated that it does not currently collect this information at the level of granularity required. Teradata will engage with the Product Provider to establish the processes and systems necessary to enable such collection and reporting in future periods.

D.Reasonable Country of Origin Inquiry ("RCOI")

Form SD requires Registrants to conduct, in good faith, a "Reasonable Country of Origin Inquiry," or "RCOI," with respect to its Necessary Conflict Minerals. The purpose of the RCOI is to determine whether any of the Registrant's Necessary Conflict Minerals originated in a Covered Country or are from recycled or scrap sources.

The Contract-Manufacturer reported the following with respect to Teradata hardware products manufactured during 2025:

•Proactively engaged with suppliers to transition away from high-risk or outdated smelters, aligning with updated RMI standards.

•36 key suppliers of components for Teradata hardware products were surveyed regarding Necessary Conflict Minerals using the RMI framework.

•As of April 21, 2026, out of the 36 key suppliers surveyed responses, 36 were deemed complete, 0 were open (e.g., awaiting responses or supplemental responses), and 0 were rejected or repeated (e.g., identity of SORs not provided or deemed to be invalid).

For a portion of the supply chain managed by a Product Provider, Teradata conducted outreach to obtain RCOI-related information. Teradata requested additional detail regarding supplier engagement and country-of-origin due diligence on two separate occasions. While the Product Provider confirmed that it maintains a conflict minerals due diligence program aligned with industry standards, it did not provide product-level or supplier-specific RCOI data in response to these requests.

Teradata will continue to engage with the Product Provider to enhance transparency and further align supply chain due diligence practices with RCOI expectations.

The RMI CMRT completed by the Contract-Manufacturer and Product Provider for 2025 regarding Teradata hardware products includes the following as of May 8, 2026:

•the Necessary Conflict Minerals contained for the manufacture of Teradata's hardware products;

•the Necessary Conflict Minerals in Teradata hardware products may have originated from the Covered Countries and did not originate exclusively from recycled or scrap sources;

•Conflict Minerals data/information received does not represent 100% of key suppliers of Necessary Conflict Minerals used in Teradata hardware products;

•all SORs of the Necessary Conflict Minerals in Teradata hardware products have not yet been identified;

•the proportion of the supply chain for which SOR identification remains incomplete cannot be quantified at this time due to the Product Provider's current inability to provide supplier-level data

•all SORs information received by Teradata's Contract-Manufacturer has been reported in a consolidated CMRT for Teradata

•all SORs information received by Teradata' Product Provider has been reported at the global level; and

•the Contract-Manufacturer and Product Provider have policies in place that address Conflict Minerals sourcing, which is publicly available at www.flex.com and www.dell.com, respectively, and state that both:

◦expect that their suppliers source from socially responsible suppliers;

◦expect that their suppliers have policies and procedures in place to ensure that products and parts supplied are DRC conflict-free;

◦expect that their suppliers provide all necessary due diligence information to confirm that all Conflict Minerals supplied are DRC conflict-free;

◦expect that their suppliers pass these requirements onto their supply chain; and

◦expect that compliance with these requirements are taken into consideration when selecting and retaining suppliers.

Teradata's hardware Contract-Manufacturer and Product Provider identified 346 SORs and their location sources through direct supplier surveys and/or submitted CMRT for the hardware products purchased in 2025. Annex I of this Report includes a list of source countries for each of the Conflict Minerals identified through that process. The audit status of the 346 identified 3TG SORs are as follows:

RMI Audit Status			RMI Audit Status Description			SORs			%
Conformant			Independently assessed and found conformant with the relevant RMI Due Diligence standard (RMAP DD or DAP)			207			59.8%
Active			Engaged in the program with a scheduled or in-progress RMI assessment but not yet conformant			7			2.0%
In Communication			Not yet active but in communication with the RMI and/or member company			1			0.3%
Communication Suspended - Not Interested			Facility has strongly communicated a lack of interest in participation			0			-%
Non-Conformant			Independently assessed and found non-conformant with the relevant RMI standard			38			11.0%
Outreach Required			Outreach needed by RMI member companies to contact entity and encourage their participation to undergo an RMI assessment			55			15.9%
Not Applicable			Not eligible for an RMI Assessment			18			5.2%
RMI Due Diligence Review - Unable to Proceed			Facilities that have not met the threshold for Due Diligence Vetting Process after a period of 6 month			20			5.8%
Smelter Not Listed			Smelter is not listed in the RMI database			0			-%

Among the identified 346 SOR declarations provided by the Contract-Manufacturer and Product Provider, approximately 59.8% have been certified as conformant with the RMAP Due Diligence Standards ("RMAP Conformant").

Due to the many company-wide declarations and the multiple levels of suppliers in Teradata's Contract-Manufacturer's and Product Provider's supply chains, Teradata is unable to determine with certainty at this time which SORs, or which countries of origin listed, provide the specific Necessary Conflict Minerals used in the products it purchases.

E.Teradata's Responses to Identified Risks

Teradata subsequently reviewed and analyzed RMI/RMAP data regarding its Contract-Manufacturer's and Product Provider's lists of identified SORs for adverse discrepancies versus the information reported by the Contract-Manufacturer and Product Provider. Teradata also engaged in subsequent follow-ups with the Contract-Manufacturer and Product Provider to collect updated supplier information from supplier surveys. Teradata did not detect any adverse discrepancies through the review and analysis of provided supplier information. With respect to SORs identified as Non-Conformant or requiring outreach, Teradata will communicate the requirements and corrective actions to Contract-Manufacturer and Product Provider, aligned with Teradata's Conflict Minerals Policy, which may include transition to alternative, RMAP-conformant sources.

The actions and determinations relevant to RCOI set forth above in this Report, the information provided by the Contract-Manufacturer and Product Provider from which Teradata derived the information in Annex I, the review of that information, reflect and summarize Teradata's RCOI process and results for Teradata hardware products distributed during 2025.

F.Continued Risk Mitigation

Teradata continues to build upon its Conflict Minerals program attributes and activities set forth in this Report. Specifically, during 2025:

•continued to include compliance with the Policy, Code of Conduct, Supplier Code of Conduct, and Business Partner Code of Conduct in the annual all-employee ethics and compliance training and/or other employee training materials;

•continued to report relevant information regarding Conflict Minerals requirements, compliance, and status to its senior management and with the Audit Committee of its Board of Directors as needed; and

•continued to monitor legal developments and guidance related to Conflict Minerals compliance (including with respect to the Conflicts Minerals Rule and related SEC interpretive guidance) and considered and/or applied relevant developments to its Conflict Minerals program.

In addition, on an ongoing basis, Teradata:

•maintains information and materials on its website;

•maintains inquiries regarding Necessary Conflict Minerals as part of its compliance due diligence questionnaire template for merger-and-acquisition candidates;

•continues to be a member of the RMI and financially supports the RMI through paying the RMI membership fees;

•maintains direct access to RMI participant data, enabling it to take measures to verify related data reported by the Contract-Manufacturer and Product Provider and to review relevant data to identify red flags and other indication of risks, rather than relying solely on the Contract-Manufacturer or Product Provider to identify and report such risks.
