Hi mhablas426 - Can you try the below measure to report the expected result with () for negative

Formatted Value =
VAR Value = [Samperiodlast year Variance]
RETURN
IF(
ABS(Value) >= 1000000,
IF(Value < 0,
"-" & FORMAT(ABS(Value) / 1000000, "0.0") & "m",
FORMAT(Value / 1000000, "0.0") & "m"
),
IF(
ABS(Value) >= 1000,
IF(Value < 0,
"-" & FORMAT(ABS(Value) / 1000, "0.0") & "K",
FORMAT(Value / 1000, "0.0") & "K"
),
FORMAT(Value, "0.00")
)
)
