## Exhibit 1.01

**Exhibit 1.02**

**Park-Ohio Holdings Corp.<br>Conflict Minerals Report**

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

**Introduction**

This Conflict Minerals Report ("Report") for the Company has been prepared pursuant to Rule 13p-1 and Form SD promulgated under the Securities Exchange Act of 1934, as amended (the "Rules"), for the reporting period from January 1, 2025 through December 31, 2025 (the "Reporting Period").

The Rules require disclosure of certain information when a company manufactures or contracts to manufacture products and the minerals specified in the Rules are necessary to the functionality or production of those products. The minerals covered by the Rules are gold, columbite-tantalite (coltan), cassiterite, and wolframite, including their derivatives consisting of tin, tungsten, and tantalum (collectively, "Conflict Minerals") and the countries by this Report are the Democratic Republic of the Congo or any adjoining country (collectively, "Covered Countries").

In this Report, unless the context otherwise indicates, "the Company", "we", "us" and "our" mean Park-Ohio Holdings Corp. and its consolidated subsidiaries.

Our operations may at times manufacture, or contract to manufacture, products for which Conflict Minerals are necessary to the functionality or production of those products. The Company does not directly purchase these minerals from smelters or refiners and works closely with our suppliers to ensure responsible sourcing of Conflict Minerals necessary to the production or functionality of its products. The Company supports the objectives of the legislation and sources materials from companies that share our values around human rights, ethics and responsibility. We expect our suppliers to comply with our Code of Business Conduct and meet the objectives of our conflict minerals policy. Our Conflict Minerals Policy, Form SD and this Report are publicly available on our website at www.pkoh.com.

This Report is not audited, nor is an independent private sector audit required for this Report under the Rules and SEC guidance.

**The Company and Our Products**

The Company operates through three reportable segments: Supply Technologies, Assembly Components and Engineered Products. These business segments utilize a supply chain that is a complex global network of tiered suppliers that directly or indirectly supply raw materials, components, and services to our global facilities.

While organizations within our Supply Technologies business segment engineer and manufacture precision cold-formed and cold-extruded products, it's our Total Supply Management™ (TSM) system that manages everything from supplying manufacturing floors with production parts and materials to strategic planning and program implementation. The principal customers of Supply Technologies are in the heavy-duty truck; automotive, truck and vehicle parts; power sports and recreational equipment; bus and coaches; electrical distribution and controls; agricultural and construction equipment; consumer electronics; HVAC; lawn and garden; semiconductor equipment; aerospace and defense; and plumbing.

Our Assembly Components division stands at the forefront of highly engineered component production, utilized in the final assembly of key OEM products including automobiles, agricultural equipment, commercial trucks, forklifts, engines, and industrial machinery. The Assembly Components division is renowned for its expertise in metallic tube manipulation, hose extrusion, rubber and plastic product molding, and hose assemblies. We also manufacture both low and high-pressure fuel rails and direct injection lines used in Gasoline Port Fuel Injection and Direct Injection Systems.

Our Engineered Products division operates a collection of niche manufacturing enterprises, each specializing in the design and production of a wide array of sophisticated products. These include state-of-the-art induction heating and melting systems, innovative tube & pipe threading and bending systems, as well as bespoke forged and machined components. The principal customers of Engineered Products are original equipment manufacturers ("OEMs") and end

users in the ferrous and non-ferrous metals, silicon, coatings, forging, foundry, heavy-duty truck, construction equipment, automotive, oil and gas, rail and locomotive manufacturing and aerospace and defense industries.

The magnitude of our products and services along with our widespread supply chain networks create a monumental task for all business units to evaluate the presence of Conflict Minerals in their products and track the sources of these applicable Conflict Minerals. We conduct analyses of our products to determine which of our products are likely to contain Conflict Minerals and, as a result, identified products that are the focus of our good faith reasonable country of origin inquiry ("RCOI").

As a contract manufacturer, we produce our products to the design and specifications of our customers. Our customers frequently specify the exact materials and components we use, and in many cases specify the suppliers from which we source these materials and components. As a result, we are limited in our ability to exercise discretion in sourcing certain materials and components. Similarly, our ability to influence the supply chain practices of suppliers selected by our customers, including their cooperation with our good faith RCOI and related due diligence, is limited. Therefore, our ability to change the sourcing of our Conflict Minerals depends on our customers' selection of suppliers and designs.

**Reasonable Country of Origin Inquiry**

The Company has conducted a good faith Reasonable Country of Origin Inquiry (RCOI) that was designed to determine whether any of the necessary conflict minerals contained in our products originated or may have originated in a Covered Country or come from recycled or scrap sources. "Necessary Conflict Minerals" are Conflict Minerals that are necessary to the functionality or production of products that we manufacture or that we contract to manufacture.

<u><br></u>

------

The Company's supply chain is complex, and there are many indirect suppliers in the supply chain between us and the mines or locations of origin of our Necessary Conflict Minerals. Therefore, we must rely on our direct and indirect suppliers to provide information about the origin of the Necessary Conflict Minerals in our products, including where possible, the smelters of the Conflict Minerals. Similarly, our suppliers may depend on their direct suppliers for this information.

To conduct our RCOI, we identified our suppliers that we believed were potentially providing materials and components that contained Necessary Conflict Minerals. In our supplier engagement, we provided information to our suppliers about the specifics of the SEC's conflict minerals rule and explained our inquiries. We requested information from our suppliers about the presence and sourcing of Conflict Minerals used in the materials and components supplied to us during the reporting period. We requested these suppliers to provide their responses using the most recent specialized Conflict Mineral Report Template ("CMRT") indicating the facility at which the Conflict Minerals were processed.

We followed up with suppliers who did not respond to our requests and with those whose answers were incomplete or unreliable.

**Due Diligence Process**

In addition to our RCOI, we conducted additional due diligence measures to conform, in all materials respects, with the due diligence framework set forth in *The Organization for Economic Co-operation and Development Due Diligence Guidance for Responsible Supply Chains of Minerals from Conflict-Affected and High-Risk Areas,* including the related supplements for gold, tin, tantalum, and tungsten (OECD Guidance). We performed the following due diligence measures:

<br> <br> <br> &nbsp;&nbsp;&nbsp;&nbsp;• <u>Step 1 - Establish strong company management systems:</u>

The Company requires each business unit to assemble a team responsible for evaluating their products for the presence of Conflict Minerals and to establish policies for internal reporting of Conflict Minerals. These teams consisted of various individuals who were familiar with the respective product lines and supplier base. These cross-functional teams included purchasing managers, engineers, metallurgists, and others to gather the information from their suppliers regarding the source of Conflict Minerals contained in our products. These teams managed the distribution and collection of CMRTs and oversaw changes in the reported data.

The Company's business units have made efforts to incorporate Conflict Minerals language within their contracts and/or agreements with suppliers, which is clearly communicated through various mechanisms.

<u><br></u>

------

<br> <br> <br> &nbsp;&nbsp;&nbsp;&nbsp;• <u>Step 2 - Identify and assess risks in the supply chain:</u>

We have worked on our system in order to increase our supply chain transparency and identify risks within our supply chain. Our continued efforts will evaluate responses from our suppliers to understand inconsistencies in which materials were reported to contain or not contain Conflict Minerals as well as the origin of those Conflict Minerals.

Because of our size, the complexity of our products, and the depth, breadth, and constant evolution of our supply chain, it is difficult to identify actors upstream from our direct suppliers. We therefore must rely on the responses from our suppliers and their ability to push the information requests on to their suppliers to obtain the required information on Conflict Minerals sourcing. We engage certain suppliers in periodic quality assessments which assist us in understanding these suppliers' compliance with our Conflict Minerals Policy.

<br> <br> <br> &nbsp;&nbsp;&nbsp;&nbsp;• <u>Step 3 - Design and implement a strategy to respond to identified risks:</u>

We continue to develop and execute processes to, i) identify suppliers that potentially provide materials and components that contain Conflict Minerals and, ii) conduct good faith RCOI of our supply chain, including a risk-based evaluation of our suppliers' responses.

<br> <br> <br> &nbsp;&nbsp;&nbsp;&nbsp;• <u>Step 4 - Carry out independent third-party audit of smelter/refiner due diligence</u>:

We do not have a direct relationship with the smelters and refiners of Conflict Minerals and do not perform direct audits of these entities within our supply chain. We support voluntary independent third-party audits for smelters and refiners under the Conflict-Free Smelter Program (CFSP).

&nbsp;&nbsp;&nbsp;&nbsp;• <u>Step 5 - Report annually on supply chain due diligence</u>:

In addition to our ongoing communications with our customers who are engaged in their own due diligence processes, we report annually to the SEC utilizing Form SD. Our reports are publicly available at www.pkoh.com.

**Results of Review**

Based on the results of our RCOI and Due Diligence Process described above, we do not have sufficient information to determine the country of origin of all the Conflict Minerals we use to manufacture and/or contract to manufacture our products and thus are unable to determine whether any of the Conflict Minerals originated in Covered Countries.

Despite our efforts to follow up with certain suppliers, we did not receive responses from all suppliers, and those who responded showed varying degrees of cooperation with our inquiries. In addition, we encountered the following challenges in obtaining and analyzing the responses we received:

<u><br></u>

------

<br> <br> <br> &nbsp;&nbsp;&nbsp;&nbsp;• We are dependent on information received from our direct suppliers to conduct our good faith RCOI process;

<br> <br> <br> &nbsp;&nbsp;&nbsp;&nbsp;• Many suppliers provided responses at a company or divisional level, and not at a product level specific to the materials and components we use in our products;

<br> <br> <br> &nbsp;&nbsp;&nbsp;&nbsp;• We have a varied supplier base with differing levels of resources and sophistication, and many of our suppliers are not themselves subject to the Rules;

&nbsp;&nbsp;&nbsp;&nbsp;• Certain suppliers were unable or unwilling to specify the smelters or refiners used for materials and components supplied to us and the information our suppliers provided was often incomplete and required significant follow-up; and

&nbsp;&nbsp;&nbsp;&nbsp;• Our ability to influence cooperation from certain suppliers was limited when our use of these suppliers was mandated by our customers or when we were multiple tiers away from the supplier in the supply chain. As a result, we have not been able to identify all of the smelters from which our suppliers sourced the Conflict Minerals.

**Steps to Mitigate Risk**

To address our ongoing obligations in 2026 under the Rules and our Conflict Minerals Policy, we intend to improve our RCOI and due diligence process. To further mitigate any risk that the Necessary Conflict Minerals in our products could benefit conflict in the Covered Countries, we expect to implement the following steps:

<br> <br> <br> &nbsp;&nbsp;&nbsp;&nbsp;• Continue to request assistance from our customers to good faith RCOI when some customers require us to source materials and components from specific suppliers;

<br> <br> <br> &nbsp;&nbsp;&nbsp;&nbsp;• Periodically survey our supply chain and follow-up when questionnaires warrant further investigation;

&nbsp;&nbsp;&nbsp;&nbsp;• Encourage the applicable supply chain vendors to provide us with the names of smelters and refiners that process the Necessary Conflict Minerals used in our products and to continue to encourage these vendors to obtain detailed information from their suppliers; and

------

&nbsp;&nbsp;&nbsp;&nbsp;• Continue to work with and to partner with trade organizations and encourage our vendors/suppliers to implement reasonable sourcing of smelters who have been designated as "conflict free" through independent smelter validation programs.
