Mizuho lowered the firm's price target on Enphase Energy to $148 from $150 and keeps a Buy rating on the shares. The firm's Q1 clean estimates are mostly in line with company guidance and consensus, saying most companies reset expectations on the Q4 earnings call and had good visibility for the quarter. The analyst says Mizuho's most significant change in its quarterly preview is regarding Q2 results for the residential solar and inverter names. The firm expects Q2 installs to be down quarter-over-quarter verses consensus assuming a Q1 trough, based on permitting data which show Q2 MWs down 7% quarter-over-quarter. Mizuho's sector preference for utility solar over residential solar is unchanged.

Baird raised the firm's price target on Block to $98 from $95 and keeps an Outperform rating on the shares. The firm expects Q1 EBITDA to beat, and guidance to be likely mildly raised. They like the shares into Q1 results and wouldn't be shocked to see them nicely over $100 in a year.
