TheStreet's Jim Cramer wouldn't own shares of engine-maker Cummins (CMI) - Get Report going into earnings, but "would buy it afterward". 

Strengths of the company include its largely solid financial position with reasonable debt levels, notable return on equity and attractive valuation levels, TheStreet Quant Ratings wrote in January. Weaknesses include a generally disappointing performance in the stock itself, weak operating cash flow and poor profit margins, according to the ratings report.  (You can view the full analysis from the report here: CMI.)

The company most recently posted fourth-quarter 2015 revenue of $4.8 billion, down from about $5.1 billion the same period a year earlier. Ebit totaled $531 million over the corresponding period ended Dec. 31, as opposed to $661 million a year ago. 

The Department of Energy said earlier this month it is awarding a $4.5 million grant to develop new technology -- plug-in hybrid electric trucks and buses. Cummins is working with Paccar, Ohio State University, National Renewable Energy Lab and Argonne National Lab, to develop this new concept for Kenworth, Peterbilt and DAD truck product line.

In February, Cummins announced a share buyback agreement with Goldman, Sachs & Co. to repurchase $500 million of its common stock. Cummins also declared a quarterly common stock dividend of 97.5 cents per share, payable on March 1 to shareholders.

Cummins, with a market cap of about $19.8 billion, makes and distributes diesel and natural gas engines, as well as engine-related component products.
