CompX International Inc. (CIX) Q3 2026 earnings review

CompX sales grow faster, but gross margin drops from spring

CompX International, a maker of security locks and stainless-steel boat parts, grew sales faster this quarter while its profitability stepped back from spring highs. Revenue rose 10% from a year ago to $44 million as towboat demand joined ongoing strength in industrial marine parts, healthcare and tool storage. Operating profit jumped by a third from last year's weak third quarter, but gross margin dropped 6 percentage points from the second quarter to about 30%.

โš–๏ธ Verdict: โšช Neutral

The story is unchanged because stronger top-line growth balanced a pre-warned drop in margins. Broadening demand across both divisions and a rebound in towboat parts put the company comfortably on track to beat last year's annual sales. On the other hand, gross margin fell below the levels of late 2025 and early 2026 once last quarter's one-off import refund went away.

The question now is whether a 30% gross margin is the normal run-rate or the start of a deeper squeeze from tariffs and imported part costs. Either product mix in marine and healthcare locks keeps full-year margins ahead of 2025, or rising factory bills pull fourth-quarter profit down further. The segment breakdown and outlook in the upcoming quarterly filing will tell.

๐Ÿ‚ Bull Case

๐ŸŸข๐ŸŸข strengthening GROWTH

Sales Growth Picked Up Across Both Divisions

CompX makes security locks and stainless-steel boat parts across two divisions: Security Products and Marine Components. For the past year, growth leaned heavily on industrial marine parts while boatbuilders and government buyers pulled back. This quarter, revenue rose 10.0% from a year ago to $44.0 million, picking up from 8.2% growth in the second quarter and 0.7% in the first.

Demand broadened across both arms of the Dallas-based manufacturer. The company credited the gain to "higher Marine Components sales to the towboat and industrial markets, and to a lesser extent, higher Security Products sales to the healthcare and tool storage markets". That marks a turnaround for towboat parts, which had dragged on results during the first half of the year.

Nine-month sales now stand at $128.2 million, up 6.3% from a year ago. In last quarter's filing, management said full-year sales should beat last year's $158.3 million total. By our math, the hardware maker now needs just $30.1 million of sales in the fourth quarter to clear that bar, which would allow a 20.2% drop from last year's fourth quarter.

What to watch: segment sales dollars in the third-quarter filing. Those figures will show whether industrial marine demand kept its first-half pace or if towboat orders did the heavy lifting.

Operating Profit Beat Last Year Through Cost Control

CompX turned 10.0% revenue growth into a 33.3% jump in operating income, which reached $6.4 million against $4.8 million a year earlier. The company pointed to "higher sales and gross margin at Security Products and Marine Components" as the drivers behind the improvement in both the quarter and the first nine months of the year.

  • Cost of sales: 70.5% of revenue, down 2.1 percentage points from 72.5% a year ago
  • Selling, general and administrative expense: 15.0% of revenue, down 0.5 percentage points from 15.5% a year ago
  • Operating margin: 14.5%, up 2.5 percentage points from 12.0% a year ago
  • Nine-month operating income: $22.4 million, up 31.8% from $17.0 million last year

Both the cost of making the products and overhead grew more slowly than revenue compared with last year's third quarter. That kept nine-month operating margin at 17.5%, well ahead of last year's full-year mark of 14.3%. What to watch: segment operating income in the quarterly filing, which will show how much of the year-on-year margin gain came from lock sales versus marine hardware.

๐Ÿป Bear Case

๐Ÿ”ด๐Ÿ”ด strengthening MARGIN contradicts narrative

Gross Margin Dropped Six Points From Last Quarter

The press release frames profitability around easy comparisons with last year's weak third quarter, noting higher gross margin across both divisions. Compared with last quarter, however, profitability stepped down sharply. Gross margin fell 6.0 percentage points from the second quarter's 35.6% peak to 29.5%, the lowest level of 2026 and below both the fourth quarter of 2025 (32.1%) and the first quarter of 2026 (32.8%).

The entire drop came from the cost of making the products, which rose from 64.4% of revenue in the second quarter to 70.5% in the third. Even though CompX added $0.4 million in quarterly revenue, cost of sales climbed by $2.9 million, cutting gross profit from $15.5 million to $13.0 million. Overhead stayed flat at $6.6 million, so operating margin fell 5.9 percentage points from 20.4% to 14.5%.

Last quarter received a boost from a one-off refund of earlier import costs and lower staff medical bills, while management warned that second-half margins could face pressure from electronic component costs, shipping and tariffs. The release repeats warnings about raw material costs "including as a result of additional or changed tariffs on imported raw materials".

What to watch: the gross margin breakdown for Security Products in the quarterly filing. A drop below 31% in that division would show that higher tariff and material costs are eating into underlying margins beyond the loss of the one-off refund.

๐Ÿ”ด persistent DISCLOSURE

Risks this quarter didn't answer

CompX does not hold earnings calls, and its short press release includes only a summary income statement. Four standing concerns cannot be checked until the full quarterly filing arrives.

  • Loans to parent company Valhi: the filing's related-party note will show how much cash CompX is lending under its $25 million unsecured credit line.
  • Unpaid customer bills in Marine Components: the balance sheet and management discussion will show whether the second quarter's 46-day collection lag returned to normal.
  • Factory equipment spending: the cash flow statement will show how much of the planned $5.5 million full-year capital budget was spent this quarter.
  • Government orders: the release did not mention government sales in either division, so the segment table must show whether government demand shrank again.

Hiring Kept Pace With Factory Demand

CompX employed approximately 600 people across its three US manufacturing plants in the third quarter, up from about 590 in the second quarter and 558 a year earlier. That 7.5% increase in staff from a year ago tracked slightly behind the 10.0% rise in sales, lifting quarterly revenue per worker by 2.3% by our math, while risk disclosures still flag "litigation related to our use of certain permitted chemicals in our production process".

๐Ÿ’ฒ Other KPIs

Interest income (26Q3) $0.7 million
โ‡˜ decelerating

Interest earned on cash and parent-company loans fell 12.5% from $0.8 million a year ago, though it edged up from $0.6 million in the second quarter. Across the first nine months of 2026, interest income dropped 20.0% to $2.0 million from $2.5 million a year earlier, trimming pre-tax profit growth by half a million dollars.

Effective tax rate (26Q3) 23.9%
โ‡’ stable

Income tax expense rose to $1.7 million from $1.4 million a year ago as pre-tax profit grew. By our math, the share of pre-tax income going to taxes dipped by 1.1 percentage points from 25.0% in last year's third quarter, and came in steady against 24.2% in the second quarter and 24.4% in the first.

Diluted share count (26Q3) 12.3 million
โ‡’ stable

Weighted average diluted shares stayed unchanged at 12.3 million, matching every quarter over the past two years. Because the lock and marine parts maker did not reduce its share count, earnings per share grew at essentially the same pace as net income, rising 29.4% to $0.44 from $0.34 a year earlier.

โ“ Key Questions

Why did gross margin drop below first-quarter levels?

Gross margin fell 6.0 percentage points from the second quarter to 29.5%, sitting 3.2 percentage points below the first quarter. Investors need to know how much of the drop came from higher tariff and electronic part costs versus the end of the second quarter's one-off import refund.

Why did the release omit a full-year outlook?

CompX provides qualitative full-year commentary in its quarterly filings but gives no outlook in its earnings releases. With nine-month sales already up 6.3%, management should clarify in the upcoming filing whether fourth-quarter margins will stay under pressure.

Did Marine Components collect its overdue customer bills?

Marine Components accounts receivable more than doubled in the second quarter, pushing collection time from 26 to 46 days. Because the earnings release omits the balance sheet, the quarterly filing must show whether customers paid those bills in the third quarter.

How much cash is currently lent to Valhi?

CompX lends spare cash to its controlling parent, Valhi, on an unsecured credit line of up to $25 million while leaving its own share buyback allowance untouched. The filing will show whether the $6.8 million balance rose or fell during the quarter.
