NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

June 30, 2015

(unaudited)

Note 1 – Organization and basis of presentation:

Organization. We (NYSE MKT: CIX) are 87% owned by NL Industries, Inc. (NYSE: NL) at June 30, 2015. We manufacture and sell component products (security products and recreational marine components). At June 30, 2015, (i) Valhi, Inc. (NYSE: VHI) owns approximately 83% of NL’s outstanding common stock and (ii) a wholly-owned subsidiary of Contran Corporation (“Contran”)  owns 93% of Valhi’s outstanding common stock. Substantially all of Contran’s outstanding voting stock is held by a family trust 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.  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 periods ended June 30, 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 – Related party transactions:

As discussed in our 2014 Annual Report, prior to 2014 we entered into an unsecured revolving demand promissory note with NL in which, as amended, we agreed to loan NL up to $40 million.  The principal amount we might lend to NL at any time under such facility was at our discretion, and we made no loans to NL at any time since prior to 2014.  In June 2015, we terminated such loan facility with NL.

Note 10 – 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 currently effective for us beginning in the first quarter of 2017.  However, the FASB has voted to issue an ASU that would defer the required adoption date by one year, and assuming such ASU is issued by the FASB, the new standard would be effective for us beginning in the first quarter of 2018.  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.

Operations Overview

We reported operating income of $4.3 million in the second quarter of 2015 compared to $3.9 million in the same period of 2014.  We reported operating income of $8.0 million for the six month period ended June 30, 2015 compared to $7.2 million for the comparable period in 2014.  Our operating income increased for the quarter and for the six month period in 2015 due to the positive impact of higher sales in 2015, primarily from an increase 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 second quarter of 2015 and $4.2 million in the first six months of 2015 compared to the respective periods in 2014, led by strong demand within Security Products for existing government customers.  Increased sales of security products to the office equipment and institutional furniture markets also contributed, to a lesser extent, to the increase in sales for the six-month period.  Marine Components sales also contributed to the increase for the six-month period 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 net sales increased less than 1% in the second quarter of 2015 compared to the same period in 2014.  As a result, gross profit as a percentage of net sales decreased over the same period.  The decrease in gross profit percentage for the second quarter is the result of lower variable margins due to relative changes in customer and product mix within Security Products.  As a percentage of net sales, cost of goods sold and resulting gross profit for the first six months of 2015 is comparable to the same period in 2014 as first quarter improvement in manufacturing efficiencies and increased leverage of fixed manufacturing costs over increased production volumes attributable to Marine Components was offset by lower second quarter variable margins within Security Products discussed above.  Gross profit dollars increased for both comparative periods due to sales growth in Security Products, and sales growth in Marine Components also positively impacted the gross profit dollars comparison in the year-to-date period.

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 property, plant and equipment. Operating costs and expenses were comparable for the second quarter of 2015 compared to the same period in 2014.  Operating costs and expenses

- 13 -

increased for the first six months of 2015 compared to the same period of 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 increased slightly for the second quarter and first six months of 2015 compared to the same periods in 2014.  These increases were primarily the result of the factors impacting gross margin 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 9% in the second quarter and 8% in the first six months of 2015 compared to the same periods last year.  The increase in net sales is primarily due to increases in sales to existing government customers of $2.0 million and $3.2 million in the second quarter and year-to-date periods, respectively, as well as increased sales of approximately $500,000 in the year-to-date period to existing office equipment and institutional furniture customers.

Gross profit as a percentage of sales for the second quarter and the first six months of 2015 decreased compared to the same periods in 2014 primarily due to relative changes in customer and product mix, resulting in lower variable margins, partially offset by increased coverage of fixed costs as a result of higher sales volumes.  Operating costs and expenses in the second quarter of 2015 were comparable to the second quarter of 2014.  For the first six months of 2015, operating costs and expenses increased approximately $338,000 primarily due to increased administrative personnel and benefits costs.  Operating income as a percentage of net sales in the second quarter and first six months of 2015 was comparable to the same periods in 2014 as a result of the factors impacting gross profit margin above offset by increased coverage of operating costs and expenses as a result of higher 2015 production volumes.

Marine Components. Marine Components net sales increased 1% and 7% in the second quarter and first six months of 2015, respectively, as compared to the same periods last year. The increase in sales is primarily due to improved demand for products sold to

- 14 -

the waterski/wakeboard boat market.  Gross profit and operating income as a percentage of sales improved for the second quarter and first six months of 2015 compared to the same periods in 2014 due to improved manufacturing efficiencies and increased leverage of fixed costs as a result of higher production volumes.

Outlook.   Sales have been very strong for the first half of 2015, with the growth over 2014 primarily attributable to requirements for certain government security applications. While demand has improved over prior year in certain other markets, including office equipment and marine components, we have not experienced broad-based demand increases in other markets or from our small business customers. 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 Security Product demand for government security applications may decrease in the second half of the year.

As in prior periods, we continue to monitor general economic conditions and sales order rates and we will 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.

Our net cash provided by operating activities for the first six months of 2015 decreased by $1.1 million as compared to the first six months of 2014.  The decrease is 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 June 30, 2015 varied by segment.  Generally, we expect our average days sales outstanding to increase from December to June as the result of a seasonal increase in sales during the second quarter as compared to the fourth quarter.   Overall, our June 30, 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 June 30, 2015 numbers below.

As shown below, our total average number of days in inventory decreased from December 31, 2014 to June 30, 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 June 30, 2014 numbers below. 

- 15 -

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 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 our $43.0 million aggregate cash and cash equivalents at June 30, 2015 were held in the U.S.

Capital Expenditures. Firm purchase commitments for capital projects in process at June 30, 2015 totaled $1.1 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 10 to our Condensed Consolidated Financial Statements.

Critical accounting policies –

There have been no changes in the first six months of 2015 with respect to our critical accounting policies presented in Management’s Discussion and Analysis of Financial Condition and Results of Operations in our 2014 Annual Report.

Related party transactions –

As previously discussed in our periodic filings with the SEC, from time to time we engage in related party transactions with affiliated companies.  In June 2015, our board of directors adopted a Policy Regarding Related Party Transactions.  Pursuant to such Policy, all related party transactions to which we are or are proposed to be a party shall be approved or ratified by our independent directors in accordance with the terms of such Policy, and such approval or ratification shall be done by our audit committee (unless another committee of our board of directors composed solely of independent directors, or all of the independent directors of our board, shall have approved or ratified the related party transaction).  For certain ongoing related party transactions to which we are a party (referred to as ordinary course of business related party transactions), such approval or ratification shall occur no less frequently than once a year.  

Following adoption of such Policy, our audit committee in June 2015 reviewed, adopted and ratified the following ordinary course of business related party transactions to which we are a party in accordance with the terms of such Policy:

- 16 -

Each of these ordinary course of business related party transactions is more fully described in the “Certain Relationships and Transactions” section of our 2015 proxy statement and Note 11 to our consolidated financial statements included in our 2014 Annual Report.  Our audit committee was not required to approve and ratify the fee we pay to Contran in 2015 under our intercorporate services agreement with Contran (such intercorporate services agreement is also described in such proxy statement and Annual Report) because such intercorporate services fee had been previously approved by all of the independent directors of our board.  See also Note 9 to our Condensed Consolidated Financial Statements.

A copy of such Policy is available on our website at www.compx.com.

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.

Evaluation of Disclosure Controls and Procedures. We maintain disclosure controls and procedures which, as defined in Exchange Act Rule 13a-15(e), means controls and other procedures that are designed to ensure that information required to be disclosed in the reports that we file or submit to the SEC under the Securities Exchange Act of 1934, as amended (the “Act”), is recorded, processed, summarized and reported, within the time periods specified in the SEC’s rules and forms. 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, has evaluated the design and operating effectiveness of our disclosure controls and procedures as of June 30, 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:

Changes in Internal Control Over Financial Reporting.  There have been no changes in our internal control over financial reporting during the quarter ended June 30, 2015 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
