Exhibit 1.01

CONFLICT MINERALS REPORT OF

THE GORMAN-RUPP COMPANY

FOR THE REPORTING PERIOD FROM

JANUARY 1 TO DECEMBER 31, 2023

Introduction

This is the Conflict Minerals¹ Report of The Gorman-Rupp Company (“we,” “our,” “us,” or the “Company”) prepared for calendar year 2023 in accordance with Rule 13p-1 (“Rule 13p-1”) under the Securities Exchange Act of 1934 (the “Act”). Numerous terms in this Report are defined in Rule 13p-1 of the Act and SEC Release No. 34-67716 (August 22, 2012) under the Act (the “Adopting Release”). The reader is referred to these sources for the definitions of defined terms contained herein.

In accordance with Rule 13p-1, we undertook efforts to determine the presence and source of the conflict minerals within our products. The Company designed its efforts in conformity with the internationally recognized due diligence framework set forth in the Organisation for Economic Co-operation and Development (“OECD”) Due Diligence Guidance for Responsible Supply Chains of Minerals from Conflict-Affected and High-Risk Areas² (“OECD Due Diligence Guidance”) and related Supplements.

The statements below are based on the activities performed to date in good faith by the Company and are based on the infrastructure and information available at the time of this filing. Factors that could affect the accuracy of these statements include, but are not limited to, incomplete supplier data or available smelter data, errors or omissions by suppliers or smelters, evolving identification of smelters, incomplete information from industry or other third-party sources, continuing guidance regarding the SEC final rules, and other issues.

Overview

Company Profile

The Gorman-Rupp Company (“Registrant”, “Gorman-Rupp” or the “Company”) was incorporated in Ohio in 1934. The Company is a leading designer, manufacturer and international marketer of pumps and pump systems for use in diverse water, wastewater, construction, dewatering, industrial, petroleum, original equipment, agriculture, fire suppression, heating, ventilating and air conditioning (“HVAC”), military and other liquid-handling applications.

We are subject to this rule as we have determined that, during 2023, conflict minerals were likely necessary to the functionality or production of products we manufactured or contracted to manufacture. The Company, as a purchaser of component parts, is many steps removed from the mining of conflict minerals.

We do not purchase raw ore or unrefined conflict minerals and we conduct no purchasing activities directly in the DRC or adjoining countries.

Conflict Minerals Policy

The Company developed a policy statement to support the goals expressed by Congress in enacting Section 1502 of the Dodd-Frank Wall Street Reform and Consumer Protection Act. The policy highlights the Company’s commitment to complying with the reporting and due diligence obligations required by the SEC rule and the Company’s expectations from its suppliers. In addition, the policy includes language encouraging suppliers to source responsibly. The policy resides on our corporate website (https://www.gormanrupp.com/hubfs/20499357/ConflictMineralsPolicy.pdf?hsLang=en ). This policy is reviewed and updated periodically as needed.

Reasonable Country of Origin Inquiry Information

We have conducted a good faith reasonable country of origin inquiry (“RCOI”) to determine whether the necessary conflict minerals originated in the DRC or an adjoining country or came from recycled or scrap sources.

The Company’s RCOI process included reviewing the products manufactured or contracted to be manufactured during the Reporting Period to identify products that should be deemed in-scope as described by the Adopting Release and conducting an inquiry of our direct suppliers of the in-scope products using the Responsible Minerals Initiative’s (“RMI”) Conflict Minerals Reporting Template (“CMRT”). Based on the results of our RCOI which indicated sourcing from the DRC or an adjoining country, we exercised due diligence on the source and chain of custody of the conflict minerals in accordance with the OECD Due Diligence Guidance. Our due diligence efforts are discussed further in this Conflict Minerals Report.

Due Diligence Program Design

The Company designed its conflict minerals program to conform, in all material respects, with the five-step framework of the OECD Due Diligence Guidance, the Supplement on Tin, Tantalum, and Tungsten, and the Supplement on Gold, specifically as they relate to our position in the minerals supply chain as a “downstream” company:

Step 1: Establish strong company management systems

Step 2: Identify and assess risks in the supply chain

Step 3: Design and implement a strategy to respond to identified risks

Step 4: Carry out independent third-party audit of smelter/refiner’s due diligence practices

Step 5: Report annually on supply chain due diligence.

Due Diligence Measures Performed by The Company

The following describes the measures taken to reasonably determine the country of origin and to exercise due diligence in the mineral supply chain in conformance with the OECD Due Diligence Guidance.

Step 1: Establish strong company management systems

Step 2: Identify and assess risks in the supply chain

We performed the following steps as part of our risk assessment process:

Step 3: Design and implement a strategy to respond to identified risks

We performed the following steps as part of our risk management plan:

Step 4: Carry out independent third-party audit of smelter/refiner’s due diligence practices

The Company is using information provided by independent third party audit programs, including the RMI RMAP, LBMA, and RJC, to confirm the existence and verify the OECD-conformance status of SORs identified during our due diligence.

For smelters that had not been audited as conformant, the Company sent a communication to encourage participation in the RMAP and requested the SOR to provide the mines and/or locations the SOR sources from to assist in identifying all countries of origin. Additionally, the Company sent communications to all suppliers that reported SORs that had not been audited as conformant to request that these suppliers contact the SORs to encourage participation in the RMAP.

Step 5: Report annually on supply chain due diligence

Accordingly, this Conflict Minerals Report has been filed with the SEC and is available on our website athttps://www.gormanrupp.com/en/governance-leadership#govt5ID

Product Description; Processing Facilities

Product Description – The Company manufactures and internationally sells pumps and pump systems.

Processing Facilities – Based on our due diligence process and the information received from our suppliers, the following facilities were identified by the Company’s suppliers as the smelters and refiners of the tin, tantalum, tungsten and/or gold present in and necessary to the functionality of products manufactured by the Company in the calendar year ended December 31, 2023. The information from our suppliers is still evolving and may contain company-level declarations. As such, this smelter list is presented in good faith as the best information we have to date. For 2023 we identified 255 SORs in our supply chain, 193 have been audited as conformant with the RMAP. This list may contain smelters that are not in our supply chain and/or there may be other smelters not yet identified in our due diligence process. We will continue to update the list as our information and the relevant third-party data from RMI, LBMA, and RJC improves.

Future Due Diligence

We will continue to communicate our expectations and information requirements to our direct suppliers. Over time, we anticipate that the amount of information available globally on the traceability and sourcing of these ores will increase and improve our knowledge. We will continue to make inquiries to our direct suppliers and undertake additional risk assessments when potentially relevant changes in facts or circumstances are identified. If we become aware of a supplier whose due diligence needs improvement, we may continue the trade relationship while that supplier improves its compliance program. We expect our suppliers to take similar measures with their suppliers to help ensure alignment throughout the supply chain.

In addition to those above, the Company will undertake the following steps during the next compliance period:
