Moody's - The ratings agency reported first-quarter profit of $0.97 per share, excluding certain items, 10 cents above estimates, with revenue also beating forecasts. Its results were helped by an increase in new debt issues.

Gilead Sciences - Gilead earned $0.48 per share, excluding certain items, for the first quarter, two cents below estimates, with revenue falling short, as well. Gilead did see higher sales of its newer products, but that was partially offset by a drop in revenue from its older HIV drugs.

Tempur-Pedic - The company reported first-quarter profit of $0.62 per share, excluding certain items, one cent above estimates, while the mattress maker's revenue also beat forecasts. However, its full-year revenue forecast was short of analysts' consensus. The company completed its purchase of competitor Sealy on March 18.

OpenTable - OpenTable earned $0.45 per share for the first quarter, excluding certain items, two cents above estimates, but its current-quarter revenue outlook fell slightly short of consensus. The online restaurant reservations provider saw growth in both its North American and international businesses, and CEO Matt Roberts is emphasizing a focus on growing mobile revenue.
