Revenue Growth
A company’s long-term sales performance can indicate its overall quality. Any business can have short-term success, but a top-tier one grows for years. Regrettably, Atmus Filtration Technologies’s sales grew at a mediocre 6.1% compounded annual growth rate over the last five years. This was below our standard for the industrials sector and is a poor baseline for our analysis.
Long-term growth is the most important, but within industrials, a half-decade historical view may miss new industry trends or demand cycles. Atmus Filtration Technologies’s annualized revenue growth of 7.1% over the last two years is above its five-year trend, which is encouraging. 
This quarter, Atmus Filtration Technologies reported year-on-year revenue growth of 16.4%, and its $527.9 million of revenue exceeded Wall Street’s estimates by 3.8%.
Looking ahead, sell-side analysts expect revenue to grow 7.8% over the next 12 months, similar to its two-year rate. This projection is above the sector average and suggests its newer products and services will help sustain its recent top-line performance.

Operating Margin
Atmus Filtration Technologies has been an efficient company over the last five years. It was one of the more profitable businesses in the industrials sector, boasting an average operating margin of 15.3%. This result was particularly impressive because of its low gross margin, which is mostly a factor of what it sells and takes huge shifts to move meaningfully. Companies have more control over their operating margins, and it’s a show of well-managed operations if they’re high when gross margins are low.
Looking at the trend in its profitability, Atmus Filtration Technologies’s operating margin rose by 4.6 percentage points over the last five years, as its sales growth gave it operating leverage.
This quarter, Atmus Filtration Technologies generated an operating margin profit margin of 18.4%, in line with the same quarter last year. This indicates the company’s cost structure has recently been stable.
Cash Is King
Although earnings are undoubtedly valuable for assessing company performance, we believe cash is king because you can’t use accounting profits to pay the bills.
Atmus Filtration Technologies has shown decent cash profitability, giving it some flexibility to reinvest or return capital to investors. The company’s free cash flow margin averaged 6.7% over the last five years, slightly better than the broader industrials sector.
Taking a step back, we can see that Atmus Filtration Technologies’s margin dropped by 1.9 percentage points during that time. If its declines continue, it could signal increasing investment needs and capital intensity.
Atmus Filtration Technologies burned through $25.5 million of cash in Q2, equivalent to a negative 4.8% margin. The company’s cash flow turned negative after being positive in the same quarter last year, suggesting its historical struggles have dragged on.
