This performance is even more electrifying when you consider that lights went out for the overall stock market in May, with the S&P 500, including dividends, dropping 6.4%.
We can attribute Enphase Energy stock's strong performance last month to the company's April 30 release of first-quarter 2019 results, which were better than Wall Street was expecting and to management forecasting continued robust growth for the second quarter. On May 1, shares rocketed 29.3% higher and continued to move upward throughout the month.
In Q1, Enphase's revenue jumped 43% year over year to $100.1 million, driven by strong adoption of the company's higher-margin, seventh-generation microinverter, the IQ 7, which accounted for 94% of all microinverter shipments. Revenue easily surpassed the company's $92.5 million guidance and the $93.4 million Wall Street consensus estimate.
Net income came in at $2.7 million -- up from a net loss of $5.1 million in the year-ago period -- which translated to earnings per share of $0.02. Adjusted for one-time items, net income was $9.5 million -- versus a loss of $1.3 million in the year-ago quarter -- which translated to EPS of $0.08, notably better than the $0.05 that analysts were expecting.
Enphase Energy shares have more than tripled since the beginning of the year, as a booming solar energy market and solid execution are propelling the company's turnaround.
Enphase Energy's management guided for a bright second quarter, with revenue expected in the range of $115 million to $125 million, which represents growth of about 52% to 65% year over year.
