(unaudited)

Note 1 – Organization and basis of presentation:

Organization. We (NYSE MKT: CIX) are 87% owned by NL Industries, Inc. (NYSE: NL) at March 31, 2015. We manufacture and sell component products (security products and recreational marine components). At March 31, 2014, (i) Valhi, Inc. (NYSE: VHI) owns 83% of NL’s outstanding common stock and (ii) a wholly-owned subsidiary of Contran Corporation owns 93% of Valhi’s outstanding common stock. Substantially all of Contran’s outstanding voting stock is held by family trusts established for the benefit of Lisa K. Simmons and Serena Simmons Connelly, daughters of Harold C. Simmons, and their children (for which Ms. Lisa Simmons and Ms. Connelly are co- trustees) or is held directly by Ms. Lisa Simmons and Ms. Connelly or persons or entities related to them, including their step-mother Annette C. Simmons, the widow of Mr. Simmons. Prior to his death in December 2013, Mr. Simmons served as sole trustee of the family trusts. Under a voting agreement entered into by all of the voting stockholders of Contran, effective in February 2014 and as amended, the size of the board of directors of Contran was fixed at five members, Ms. Lisa Simmons, Ms. Connelly and Ms. Annette Simmons (and in the event of their death, their heirs) each has the right to designate one of the five members of the Contran board and the remaining two members of the Contran board must consist of members of Contran management. Ms. Lisa Simmons, Ms. Connelly, and Ms. Annette Simmons each serve as members of the Contran board. The voting agreement expires in February 2017 (unless Ms. Lisa Simmons, Ms. Connelly and Ms. Annette Simmons otherwise unanimously agree), and the ability of Ms. Lisa Simmons, Ms. Connelly, and Ms. Annette Simmons to each designate one member of the Contran board is dependent upon each of their continued beneficial ownership of at least 5% of the combined voting stock of Contran. Consequently, Ms. Lisa Simmons, Ms. Connelly and Ms. Annette Simmons may be deemed to control Contran, Valhi, NL and us.

Basis of presentation. Consolidated in this Quarterly Report are the results of CompX International Inc. and its subsidiaries. The unaudited Condensed Consolidated Financial Statements contained in this Quarterly Report have been prepared on the same basis as the audited Consolidated Financial Statements included in our Annual Report on Form 10-K for the year ended December 31, 2014 that we filed with the Securities and Exchange Commission (“SEC”) on March 5, 2015 (the “2014 Annual Report”). In our opinion, we have made all necessary adjustments (which include only normal recurring adjustments) in order to state fairly, in all material respects, our consolidated financial position, results of operations and cash flows as of the dates and for the periods presented. We have condensed the Consolidated Balance Sheet at December 31, 2014 contained in this Quarterly Report as compared to our audited Consolidated Financial Statements at that date, and we have omitted certain information and footnote disclosures (including those related to the Consolidated Balance Sheet at December 31, 2014) normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”). Our results of operations for the interim period ended March 31, 2015 may not be indicative of our operating results for the full year. The Condensed Consolidated Financial Statements contained in this Quarterly Report should be read in conjunction with our 2014 Consolidated Financial Statements contained in our 2014 Annual Report.  

Unless otherwise indicated, references in this report to “we”, “us” or “our” refer to CompX International Inc. and its subsidiaries, taken as a whole.

Note 9 – Recent Accounting Pronouncements:

In May 2014, FASB issued Accounting Standards Update (“ASU’) No. 2014-09, Revenue from Contracts with Customers (Topic 606).  This standard replaces existing revenue recognition guidance, which in many cases was tailored for specific industries, with a uniform accounting standard applicable to all industries and transactions.  The new standard is effective for us beginning in the first quarter of 2017.  Entities may elect to adopt ASU No. 2014-09 retrospectively for all periods for all contracts and transactions which occurred during the period (with a few exceptions for practical expediency) or retrospectively with a cumulative effect recognized as of the date of adoption.  ASU No. 2014-09 is a fundamental rewriting of existing GAAP with respect to revenue recognition, and we are still evaluating the effect the standard will have on our Consolidated Financial Statements.  In addition, we have not yet determined the method we will use to adopt the standard.

Overview

We are a leading manufacturer of engineered components utilized in a variety of applications and industries. Through our Security Products segment we manufacture mechanical and electronic cabinet locks and other locking mechanisms used in recreational transportation, postal, office and institutional furniture, cabinetry, tool storage and healthcare applications. We also manufacture stainless steel exhaust systems, gauges and throttle controls for the recreational marine and other industries through our Marine Components segment.

We reported operating income of $3.7 million in the first quarter of 2015 compared to $3.3 million in the same period of 2014.  Our operating income increased in 2015 primarily due to the positive impact of higher sales in 2015, primarily from an increase in sales to existing Security Products customers.

Our product offerings consist of a significantly large number of products that have a wide variation in selling price and manufacturing cost, which results in certain practical limitations on our ability to quantify the impact of changes in individual product sales quantities and selling prices on our net sales, cost of goods sold and gross profit.  In addition, small variations in period-to-period net sales, cost of goods sold and gross profit can result from changes in the relative mix of our products sold.

Results of Operations

Net sales. Net sales increased $2.1 million in the first quarter of 2015 compared to the same period of 2014, led by strong demand within Security Products for an existing government customer and to a lesser extent increased demand for fuel security products as well as increased sales to the office equipment market.  Sales of Marine Components also contributed to the increase in sales primarily as a result of improved demand for products sold to the waterski/wakeboard boat market.  Relative changes in selling prices did not have a material impact on net sales comparisons.

Cost of goods sold and gross profit. Cost of goods sold as a percentage of sales decreased by less than 1% in the first quarter of 2015 compared to the same period in 2014. As a result, gross profit as a percentage of sales increased over the same period. Gross profit dollars increased due to sales growth in both the Security Products and Marine Components segments.  The increase in gross profit percentage is attributable to Marine Components, which achieved improvement in manufacturing efficiencies as well as increased leverage of fixed manufacturing costs over increased production volumes.  

Operating costs and expenses. Operating costs and expenses consist primarily of sales and administrative related personnel costs, sales commissions and advertising expenses, as well as gains and losses on plant, property and equipment.  Operating costs and expenses increased in the first quarter of 2015 as compared to the same period in 2014 primarily due to increased administrative personnel costs to support the growth in volume for Security Products.

Operating income. As a percentage of net sales, operating income for the first quarter of 2015 increased slightly compared to the same period of 2014 and was primarily impacted by the factors impacting gross profit percentage and operating costs and expenses above.

Provision for income taxes.  A tabular reconciliation of our statutory income tax provision to our actual tax provision is included in Note 7 to the Condensed Consolidated Financial Statements. Our operations are wholly within the U.S. and therefore our effective income tax rate is primarily reflective of the U.S. federal statutory rate.

Segment Results

The key performance indicator for our segments is operating income.

Security Products. Security Products net sales increased 7% in the first quarter of 2015 compared to the same period last year. The increase in sales is primarily due to an increase of approximately $1.2 million in sales of products to existing government customers as well as increased demand of $240,000 for fuel security products and increased sales of $239,000 to existing office equipment customers.  Gross profit as a percentage of sales in 2015 was comparable to the same period in 2014.  Operating income as a percentage of net sales in the first quarter of 2015 was slightly lower than the first quarter of 2014 due to increased operating costs and expenses, including increased administrative personnel and benefits costs of approximately $213,000.  

Marine Components. Marine Components net sales increased 15% in the first quarter of 2015 as compared to the same period last year. The increase in sales is primarily due to improved demand for products sold to the waterski/wakeboard boat market. Gross profit and operating income as a percentage of net sales improved in the first quarter of 2015 compared to the first quarter of 2014 due to improved manufacturing efficiencies and increased leverage of fixed costs as a result of higher volumes.

Outlook. First quarter sales reflect continued strong demand for our products. The primary driver continues to be existing original equipment manufacturer (“OEM”) customers, including requirements for certain government security applications. While demand has been particularly strong in certain markets, including electronic locks, office furniture and marine components, we have not experienced the consistently strong demand from our small business customers that we might expect in a broader economic upturn. We continue to experience the benefits of diversification in our product offerings and ongoing innovation to serve new markets. We anticipate continued strong demand for our products throughout 2015, though we expect security product demand for government security applications to decrease in the second half of the year.

As in prior periods, we will continue to monitor general economic conditions and sales order rates and respond to fluctuations in customer demand through continuous evaluation in staffing levels and consistent execution of our lean manufacturing and cost improvement initiatives. Additionally, we continue to seek opportunities to gain market share in markets we currently serve, to expand into new markets and to develop new product features in order to mitigate the impact of changes in demand as well as broaden our sales base.

Liquidity and Capital Resources

Consolidated cash flows –

Operating activities. Trends in cash flows from operating activities, excluding changes in assets and liabilities have generally been similar to the trends in operating earnings. Changes in assets and liabilities result primarily from the timing of production, sales and purchases. Changes in assets and liabilities generally tend to even out over time. However, period-to-period relative changes in assets and liabilities can significantly affect the comparability of cash flows from operating activities.

We generally report a net use of cash from operating activities in the first three months of each year due to seasonal changes in the level of our working capital.  Our net cash used by operating activities for the first three months of 2015 increased by $667,000 as compared to the first three months of 2014 primarily due to the net effects of:

Relative changes in working capital can have a significant effect on cash flows from operating activities.  As shown below, the change in our average days sales outstanding from December 31, 2014 to March 31, 2015 varied by segment.  Generally, we expect our average days sales outstanding to increase from December to March as the result of a seasonal increase in sales during the first quarter as compared to the fourth quarter.   Overall, our March 31, 2015 days sales outstanding compared to December 31, 2014 is in line with our expectations. For comparative purposes, we have provided December 31, 2013 and March 31, 2014 numbers below.

As shown below, our total average number of days in inventory decreased from December 31, 2014 to March 31, 2015 primarily as a result of intentional 2014 fourth quarter inventory builds in each of our segments to prepare for first quarter 2015 sales.  The variability in days in inventory among our segments primarily relates to the differences in the complexity of the production processes and therefore the length of time it takes to produce end-products.  For comparative purposes, we have provided December 31, 2013 and March 31, 2014 numbers below.

Investing activities. Investing activities consisted only of those capital expenditures made in the normal course of business and were comparable for the noted periods.  

Financing activities.  Financing activities consisted only of quarterly cash dividends ($0.05 per share) and were comparable for the noted periods.

Future cash requirements –

Liquidity . Our primary source of liquidity on an on-going basis is our cash flow from operating activities, which is generally used to (i) fund capital expenditures, (ii) repay short-term or long-term indebtedness incurred primarily for capital expenditures, investment activities or reducing our outstanding stock and (iii) provide for the payment of dividends (if declared). From time-to-time, we will incur indebtedness, primarily to fund capital expenditures or business combinations. In addition, from time-to-time, we may also sell assets outside the ordinary course of business, the proceeds of which are generally used to repay indebtedness (including indebtedness which may have been collateralized by the assets sold) or to fund capital expenditures or business combinations.

Periodically, we evaluate liquidity requirements, alternative uses of capital, capital needs and available resources in view of, among other things, our capital expenditure requirements, dividend policy and estimated future operating cash flows. As a result of this process, we have in the past and may in the future seek to raise additional capital, refinance or restructure indebtedness, issue additional securities, modify our dividend policy or take a combination of such steps to manage our liquidity and capital resources. In the normal course of business, we may review opportunities for acquisitions, joint ventures or other business combinations in the

- 14 -

component products industry. In the event of any such transaction, we may consider using available cash, issuing additional equity securities or increasing our indebtedness or that of our subsidiaries.

We believe that cash generated from operations together with cash on hand, as well as our ability to obtain external financing, will be sufficient to meet our liquidity needs for working capital, capital expenditures, debt service and dividends (if declared) for both the next 12 months and five years. To the extent that our actual operating results or other developments differ from our expectations, our liquidity could be adversely affected.

All of the $41.2 million aggregate cash and cash equivalents at March 31, 2015 were held in the U.S.

Capital Expenditures. Firm purchase commitments for capital projects in process at March 31, 2015 totaled $1.6 million.  Our 2015 capital investments are limited to those expenditures required to meet our expected customer demand and those required to properly maintain our facilities and technology infrastructure.

Commitments and Contingencies. There have been no material changes in our contractual obligations since we filed our 2014 Annual Report, and we refer you to that report for a complete description of these commitments.

Off-balance sheet financing arrangements –

We do not have any off-balance sheet financing agreements other than the operating leases discussed in our 2014 Annual Report.

Recent accounting pronouncements –

See Note 9 to the Condensed Consolidated Financial Statements.

Critical accounting policies –

Although we believe that the expectations reflected in such forward-looking statements are reasonable, we do not know if our expectations will prove to be correct. Such statements by their nature involve substantial risks and uncertainties that could significantly impact expected results, and actual future results could differ materially from those described in such forward-looking statements. Among the factors that could cause actual future results to differ materially are the risks and uncertainties discussed in this Quarterly Report and those described from time to time in our other filings with the Securities and Exchange Commission.

- 15 -

Should one or more of these risks materialize or if the consequences worsen, or if the underlying assumptions prove incorrect, actual results could differ materially from those currently forecasted or expected. We disclaim any intention or obligation to update or revise any forward-looking statement whether as a result of changes in information, future events or otherwise.

We are exposed to market risk from changes in interest rates and raw material prices. There have been no material changes in these market risks since we filed our 2014 Annual Report, and we refer you to Part I, Item 7A – “Quantitative and Qualitative Disclosure About Market Risk” in our 2014 Annual Report. See also Note 8 to the Condensed Consolidated Financial Statements.

Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information we are required to disclose in the reports that we file or submit to the SEC under the Act is accumulated and communicated to our management, including our principal executive officer and our principal financial officer, or persons performing similar functions, as appropriate to allow timely decisions to be made regarding required disclosure. Our management with the participation of David A. Bowers, our Vice Chairman of the Board and Chief Executive Officer, and James W. Brown, our Vice President, Chief Financial Officer and Controller, have evaluated the design and operating effectiveness of our disclosure controls and procedures as of March 31, 2015. Based upon their evaluation, these executive officers have concluded that our disclosure controls and procedures are effective as of the date of such evaluation.

Internal Control Over Financial Reporting. Our management is responsible for establishing and maintaining adequate internal control over financial reporting which, as defined in Exchange Act Rule 13a-15(f), means a process designed by, or under the supervision of, our principal executive and principal financial officers, or persons performing similar functions, and effected by our board of directors, management and other personnel, to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles, and includes those policies and procedures that:
