Net income: 8 periods, Q4 FY16 to Q3 FY18: not printed by the filing, worked out from its own lines.

EPS, diluted: 8 periods, Q4 FY12 to Q4 FY25: quarter's net income to common over its shares, to the cent.

Diluted shares: 5 periods, Q4 FY12 to Q4 FY17: share-days: the 12-month average less the 9-month, weighted by days. 8 periods, Q4 FY18 to Q4 FY25: a loss quarter: its basic count, share-days: the 12-month average less the 9-month, weighted by days.

From each company's 10-Q and 10-K filings, the newest version of each figure. Quarters are as filed (a fourth quarter is the year less its first nine months), fiscal years as the 10-K prints them, restated where a later 10-K restated them, and balance sheet lines as of the period's end. A quarter whose 10-Q isn't filed yet is from the company's results release. Growth is on the same period a year earlier. A dash is a period with no figure for the line: the filing doesn't print it, or it hasn't been read yet.
