Refinitiv Methodology is not available, my guess for now is that earnings are most likely something like operating earnings or EBITDA.
SP Global, also reports both operating earnings per share and as reported earnings per share.
Since small-cap companies are known to be very indebted, a lot of their operating earnings are most likely going to interest expenses, and with refinancing rates higher than before, their expenses are more likely continuing to increase. (this is part of my arguments for companies needing to continue cutting costs since small companies are the vast majority in the country and the majority of employment comes from them)
