ION Geophysical Corporation

Conflict Minerals Report

For The Calendar Year Ended December 31, 2015

This report for the calendar year ended December 31, 2015 is presented by ION Geophysical Corporation (the “Company”) to comply with Rule 13p-1 under the Securities Exchange Act of 1934 (the “Rule”). When used in this report, “Company,” “we,” “our,” and “us” refer to ION Geophysical Corporation and its consolidated subsidiaries, except where the context otherwise requires or as otherwise indicated.

The Securities and Exchange Commission (the “SEC”) adopted the Rule 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. The Rule imposes certain obligations on SEC registrants whose manufactured products contain conflict minerals that are necessary to the functionality or production of their products. Conflict Minerals are defined as cassiterite, columbite-tantalite, gold, wolframite, or their derivatives, which are limited to tin, tantalum, tungsten, and gold (collectively, “3TG”). These requirements apply to registrants whatever the geographic origin of the conflict minerals and whether or not the minerals fund armed conflict.

I. Introduction

A. Company

The Company is a leading provider of technology-driven solutions to the global oil & gas industry. Our offerings are designed to help companies reduce risk and optimize assets throughout the E&P lifecycle. Our business is comprised of four reporting segments: Solutions, Software, Ocean Bottom Services and Systems. The Company acquires and processes seismic data from seismic surveys in regional data programs, which then become part of its seismic data library. 3TG can be found in some of the electronic components and materials supplied to us for inclusion in marine hardware and geophone products manufactured by the Company.

B. Supply Chain Overview

The Company's supply chain is complex. The Company’s manufacturing processes for its marine hardware and geophone products require a large volume of components that the Company purchases from contract manufacturers as an alternative to the Company’s own manufacturing of products. The Company is many levels removed from the actual mining of conflict minerals. Further, the Company does not make purchases of 3TG directly from smelters or refineries and makes no direct purchases of components in or from the Democratic Republic of the Congo and surrounding countries (“Covered Countries”). As a result of its extensive use of suppliers, the Company is required to rely upon its direct suppliers to provide information on the origin of the 3TG contained in products, components and materials supplied to the Company, including sources of 3TG that are supplied to the direct suppliers from lower tier suppliers.

C. Conflict Minerals Policy

The Company has adopted the Conflict Minerals Policy Statement set forth below, which governs the supply chain of conflict minerals from Covered Countries. The policy is publicly available in the Investor Relations - Corporate Governance portion of the Company’s website at www.iongeo.com.

1

D. Production Description

The Company manufactures products that may contain 3TG, such as marine hardware and geophone products.

Suppliers were requested to use the Conflict Free Sourcing Initiative’s (CFSI’s) Conflict Minerals Reporting Template (CMRT) to identify 3TG smelters and refiners (SORs) and associated countries of origin.

See Annex A for a summary of verified smelters. Verified smelters are those listed by the Conflict Free Sourcing Initiative or the U.S. Department of Commerce as known metal processors, or otherwise determined to be metal processors through Source Intelligence’s research.

See Annex B for the list of Countries of Origin that the identified SORs are believed to include.

II. Due Diligence Performed

A. Design of Due Diligence Measures

The Company’s due diligence process is based on the Organization for Economic Cooperation and Development’s (OECD’s) Due Diligence Guidance for Responsible Supply Chains of Minerals from Conflict-Affected and High-Risk Areas and accompanying Supplements. It is important to note that the OECD Guidance was written for both upstream and downstream companies in the supply chain. Upstream companies refer to those between the mine and SORs. As such, the companies typically include miners, local traders or exporters from the country of mineral origin, international concentrate traders and SORs. Downstream companies refer to those entities between the SORs and retailer. As such, the companies typically include metal traders and exchanges, component manufacturers, product manufacturers, original equipment manufacturers (OEMs) and retailers.

As the Companyis a downstream company in the supply chain, our due diligence practices were tailored accordingly. OECD Due Diligence Guidance for Responsible Supply Chains of Minerals from Conflict-Affected and High-Risk Areas, Supplement on Tin, Tantalum and Tungsten and Supplement on Gold, 2013; http://www.oecd.org/daf/inv/mne/GuidanceEdition2.pdf.

B. Due Diligence Measures Implemented

Due Diligence measures undertaken bythe Company included the following:

• adopted a conflict minerals policy (our conflict minerals policy is publicly available in the Investor Relations - Corporate Governance portion of the Company’s website at www.iongeo.com);

• assembled an internal, cross-functional team to support supply chain due diligence;

• established a system of controls and transparency over the mineral supply chain;

• implemented internal measures taken to strengthen company engagement with suppliers;

• engaged the services of a third-party vendor, Source Intelligence, to contact the identified suppliers via email and telephone, manage responses and identify the SORs in the supply chain;

• designed and implemented a strategy to respond to supply chain risks;

• reported risk management findings to senior management;

• undertook additional fact and risk assessments for risks requiring mitigation, or after a change of circumstances; and

• report annually on Supply Chain Due Diligence.

2

C. Steps to Improve Due Diligence

The Company will endeavor to improve continuously upon its supply chain due diligence efforts via the following measures:

• continue to assess the presence of 3TG in its supply chain;

• clearly communicate expectations with regard to supplier performance, transparency and sourcing;

• increase the response rate for theReasonable Country of Origin Inquiry (RCOI) process; and

• continue to compare RCOI results to information collected via independent conflict free smelter validation programs such as the CFSI’s Conflict-Free Smelter Program.

III. Conflicts Minerals Disclosure

In accordance with the execution of this policy, the Company has concluded in good faith that during 2015,

a) The Company manufactured products for which “conflict minerals” (as defined in Section 1502(e)(4) of the Dodd-Frank Wall Street Reform and Consumer Protection Act) are necessary to the functionality or production.

b) Based on a RCOI and subsequent due diligence, the Company does not have concrete findings on whether its sourcing practices directly or indirectly funded armed groups in the Covered Countries. As a result, the Company’s products are DRC Conflict Undeterminable.

The Company is unable to determine whether various components/materials are DRC conflict free. The Company does not have sufficient information from suppliers or other sources to conclude whether the necessary conflict minerals originated in the Covered Countries and, if so, whether the necessary conflict minerals were from recycled or scrap sources, were DRC conflict free, or have not been found to be DRC conflict free. On the basis of the due diligence measures taken above, a total of 155 suppliers were identified as in-scope for conflict mineral regulatory purposes and contacted as part of the RCOI process. The survey response rate among these suppliers was 62%. Of these responding suppliers, 55% responded yes as to having one or more of the regulated metals (3TG) as necessary to the functionality or production of the products they supply to the Company.

IV. Independent Private Sector Audit

Based on the Company’s declaration of DRC conflict undeterminable, a private sector audit is not required.
