Cummins: A Power, Diesel & Natural Gas Engines Profile

When most people think of Cummins, they think of engines. But power generation has become an increasingly important part of the company’s story.

Cummins (CMI) designs and manufactures power systems, including diesel and natural gas engines, electric powertrains, and specialized components like turbochargers and transmissions. The company generates revenue by selling these power solutions and providing long-term maintenance services to truck manufacturers and industrial equipment operators. The company is headquartered in Columbus, IN.

Keys for Success

Cummins continues to benefit from rising demand for backup power in data centers and other mission-critical settings, which is supporting the Distribution and Power Systems segments. This segment delivered exceptional performance in 1Q2026, setting a new margin record as demand from global data centers and industrial end users surged. Sales in this segment grew 19% year over year, supported by nearly 28% growth in power generation product lines.

Cummins delivered adjusted earnings of $6.15 per share in 1Q2026, up 3.2% year over year and 9.8% above consensus estimates. Revenues of $8.40 billion rose 2.7% from the year-ago quarter.
The quarter reflected solid execution,  highlighted by an adjusted EBITDA margin of 17.7% of sales. 

Cummins is advancing its long-term growth and decarbonization goals through strategic investments in clean energy technologies. Its HELM platform boosts efficiency and cuts emissions, while growing electrolyzer orders and the Amplify Cell Technologies JV strengthen hydrogen and battery supply chains.

Engine results have been mixed. While international sales offset weaker North American activity, the Engine segment saw a pronounced margin squeeze. Engine EBITDA margin fell to 10.4%, down over six percentage points, as lower demand for heavy-duty trucks and buses in North America was only partially offset by strong construction markets in China.

The acquisition of Meritor in 2022 has enhanced CMI’s position as a top provider of integrated powertrain solutions for both internal combustion and electric vehicles. This deal expanded Cummins’ components business, opening up new growth avenues.

Cash generation improved year over year, with operating cash flow of $309 million in the quarter. In July, the company raised its quarterly dividend by 10% to $2 per share, marking its 16th straight annual increase. It increased dividends 5 times in the last 5 years, with an annualized growth of 8.17%. Standard & Poor’s has assigned Cummins an A credit rating.

Keys for Concern

The company operates in a highly competitive global market, facing competition from manufacturers of diesel, gasoline, natural gas, hydrogen, and electrified technologies. High R&D and engineering expenses of the Accelera (hydrogen and electrified power systems) are hurting the firm’s margins. Cummins continues to plan elevated capital expenditures to support growth and new product launches. High capital requirement may hurt the company’s near-term cash flows.

Mark Notes

For most of the past decade, owning Cummins meant betting on heavy trucks, diesel engines, and the health of the freight economy. But that narrative is quickly becoming outdated. The company has spent 2026 pivoting into something investors didn’t expect: a strategic player in the AI electricity shortage.

On June 16, Cummins signed an agreement with Circe Energy to supply natural gas generator sets for a behind-the-meter microgrid that will power a high-performance computing campus in Texas. The generators sit on-site and act as the primary power source, so the campus runs without leaning  on the public grid. 

The investment thesis is that Cummins can continue its pivot into power while engines show early signs of recovery.
