Check out the companies making headlines before the bell:

Tesla — Morgan Stanley cut its "worst case scenario" for the automaker's shares to $10 per share from $97 a share, citing Tesla's rising debt levels and geopolitical exposure. The firm's price target for the stock remains at $230 a share, however, with an "equal-weight" rating.
Kohl's — The retailer reported adjusted quarterly profit of 61 cents per share, missing consensus by 7 cents a share. Revenue was above forecasts, but comparable-store sales were down 3.4% versus estimates of a 0.2% drop.

J.C. Penney — J.C. Penney lost an adjusted 46 cents for the first quarter, 8 cents a share more than Wall Street had anticipated. Revenue was in line with expectations, but a same-store sales drop of 5.5% was more than the 4.2% decline that analysts had predicted.
