## Exhibit 1.01

**Exhibit 1.01**

**NUWELLIS, INC.**

**Conflict Minerals Report**

For the reporting period from January 1, 2025, to December 31, 2025

**Background**

This Conflict Minerals Report (the ***"Report"***) of Nuwellis, Inc. (***"we"***, ***"us"*** or the ***Company"***) has been prepared pursuant to Rule 13p-1 and Form SD (the ***"Rule"***) promulgated under the Securities Exchange Act of 1934, as amended, for the reporting period January 1, 2025, to December 31, 2025.

The Rule imposes certain reporting obligations on companies who manufacture or contract to manufacture products containing certain specified minerals that are necessary to the functionality or production of the Company's products. The specified minerals, which we collectively refer to in this Report as the ***"Conflict Minerals,"*** are gold, columbite-tantalite (coltan), cassiterite and wolframite, including their derivatives, which are limited to tantalum, tin and tungsten (***"3T"***). The ***"Covered Countries"*** for the purposes of the Rule and this Report are the Democratic Republic of the Congo, the Republic of the Congo, the Central African Republic, South Sudan, Uganda, Rwanda, Burundi, Tanzania, Zambia and Angola.

This Report relates to the process undertaken by the Company for the Company's products that contain Conflict Minerals and were manufactured, or contracted to be manufactured, during calendar year 2025.

**Company Overview**

We are a medical technology company focused on commercializing the Aquadex SmartFlow® System. The Aquadex SmartFlow system is indicated for temporary (up to 8 hours) or extended (longer than 8 hours in patients who require hospitalization) use in adult and pediatric patients weighing 20 kg or more whose fluid overload is unresponsive to medical management, including diuretics. The Aquadex SmartFlow System is referred to herein as, the "***Aquadex System.***"

The Aquadex System consists of: (i) a console, a piece of capital equipment containing electromechanical pumps and an LCD screen (the ***"Console"***), (ii) a one-time disposable blood set (the ***"Aquadex Blood Set"***), an integrated collection of tubing, filter, sensors, and connectors that contain and deliver the blood from and back to the patient, and (iii) a disposable catheter (the ***"Aquadex Catheter"***), a small, dual-lumen catheter designed to access the peripheral venous system of the patient and to simultaneously withdraw blood and return filtered blood to the patient. Conflict Minerals are necessary to the functionality or production of certain critical components of the Aquadex System (the ***"Covered Products"***) that were manufactured, or contracted to be manufactured, by the Company during calendar year 2025.

------

**Manufacturing of the Console, Aquadex Blood Set and Aquadex Catheter during 2025**

As of the third quarter of 2018, we manufactured all of the Covered Products in-house in our Eden Prairie, Minnesota, facility. On May 12, 2025, The Company announced it had entered into a contract manufacturing agreement with KDI Precision Manufacturing ("KDI") which agreed to take over assembly responsibilities for the Aquadex SmartFlow® Console, AquaFlexFlow<sup>®</sup> Blood Circuits, and dELC<sup>®</sup> Catheters. KDI manufactured it first console for us in October 2025. It commenced commercial production of our blood circuits and catheters in January 2026.

**The Company's Due Diligence Process**

The Company formed a cross-functional team to address Conflict Minerals in the supply chain for the Aquadex System. This team included members of the Quality and Operations organizations. This team conducted a good faith reasonable country of origin inquiry (***"RCOI"***) to identify and trace Conflict Minerals in the Company's supply chain, using procedures and tools recommended or provided by the Responsible Minerals Initiative (formerly the Conflict-Free Sourcing Initiative) and the Organisation for Economic Cooperation and Development Due Diligence Guidance for Responsible Supply Chain of Minerals from Conflict-Affected and High Risk Areas: Third Edition, including the related supplements on gold, tin, tantalum and tungsten (the ***"OECD Guidance"***).

This RCOI was reasonably designed to determine whether any of the Conflict Minerals originated in the Covered Countries and whether any of the Conflict Minerals may be from recycled or scrap sources. The Company does not purchase Conflict Minerals directly from mines, smelters or refiners; rather the Company contracts to manufacture and assemble products from materials and compounds acquired from third parties. The supply chain for the Covered Products is complex, and there are many third parties in the supply chain between the ultimate manufacturer of the Covered Products and the original sources of Conflict Minerals. Therefore, the Company must rely, and has relied, on its suppliers to provide information in their responses to the Company's inquiries regarding the existence of Conflict Minerals in any materials or products supplied to the Company and the source of such Conflict Minerals, if any.

The Company's direct suppliers are similarly reliant upon information provided by their suppliers. Our measures can provide only reasonable, not absolute, assurance regarding the source and chain of custody of the necessary Conflict Minerals.

The Company determined that 27 suppliers were within the scope of the Company's RCOI during calendar year 2025 and contacted all 27 suppliers, requesting that such suppliers provide Conflict Minerals data by completing the Conflict Mineral Reporting Template, a supply chain survey tool provided by the Responsible Minerals Initiative. The Company's reviewed the information received from such suppliers.

------

**Results of Due Diligence Process**

The Company received responses from 17 (3TG) suppliers. 5 (3TG) suppliers confirmed that, based upon the representation or warranty of their own supplier(s), no Conflict Minerals contained in the components supplied to the Company were sourced from a Covered Country. 4 (3TG) suppliers responded that 3T included in its product line is sourced from Covered Countries. 5 (3TG) suppliers responded that they are not able to determine whether any of the 3T and/or gold in its product line originates from a Covered Country since, to their knowledge, no refiners were sourcing from a Covered Country, but they did not receive responses from all of their suppliers. 3 (3TG) suppliers provided incomplete replies without completing the Conflict Mineral Reporting Template, and the Company is unable to reach a determination from the information they provided.

The Company did not receive a response from 10 (3TG) suppliers. The Company is unable to determine the facilities used to process or the country of origin of all of the necessary Conflict Minerals in the products provided by its suppliers. The Company does not believe it has significant leverage with its existing suppliers, given the minimal amount of purchases relative to the size of the suppliers, to have an impact on the purchasing and sourcing decisions of its suppliers

**Further Efforts**

The Company has yet to adopt a formal policy relating to the Conflict Minerals that incorporates the standards set forth in the OECD Guidance, although it has implemented certain provisions in practice. The Company generally is committed to the responsible sourcing of materials of its products and supports greater transparency with regard to its supply chain but is taking a reasonable, measured approach in responding to the requirements of the Rule.

The Company expects to take the following steps, among others, to improve its due diligence measures and to further mitigate the risk that the necessary Conflict Minerals contained in the Company's products, finance or benefit armed groups in the Covered Countries: (i) continuing to identify any products that the Company manufactures or contracts to manufacture that contain Conflict Minerals; (ii) continuing to engage with suppliers to obtain current, accurate and complete information about the supply chain; and (iii) following up appropriately when information provided by suppliers appears to be incomplete or inaccurate. As noted above, the Company's efforts and impact are limited due to its minimal purchasing relative to the size of its suppliers.
