CVS Health (CVS) – The drug store and pharmacy benefits management company earned $2.04 per share in the first quarter, above the consensus estimate of $1.72 a share.

The maker of the Roomba robotic vacuum's revenue exceeded estimates as well, however the stock tumbled 8.6% in the premarket on concerns about shipping and component costs.

Pfizer (PFE) – The drugmaker beat estimates by 16 cents a share, with quarterly profit of 93 cents per share. Revenue also came in above forecasts and the company raised its full-year guidance as sales of its Covid-19 vaccine continue to be stronger than expected. Additionally, the Food and Drug Administration is set to authorize the vaccine for use in adolescents aged 12-15, according to federal officials familiar with the plan who spoke to The New York Times. Pfizer shares added 1.3% in premarket trading.

Vaxart (VXRT) – Vaxart surged 18.6% in premarket trading after it reported positive results in a phase 1 trial of its oral Covid-19 vaccine. Vaxart said the vaccine could be just as effective as the injected vaccines developed by Pfizer and Moderna (MRNA).

Under Armour (UAA) – The athletic apparel maker's stock climbed 2.8% in premarket action after it reported first-quarter profit of 16 cents per share, well above the 3 cents a share consensus estimate.

Avis Budget (CAR) – Avis Budget lost 46 cents per share for the first quarter, smaller than the loss of $2.16 a share predicted by analysts. The car rental company's revenue beat Wall Street forecasts as well amid a jump in demand and more solid pricing for car rentals. The stock fell 1.4% in premarket action despite the upbeat results.

Qiagen (QGEN) – Qiagen reported better-than-expected earnings and sales for its latest quarter, as the genetic testing company saw increasing demand for non-coronavirus products as well as strength in its Covid-19 testing business.

SmileDirectClub (SDC) – SmileDirectClub said its current-quarter sales will be hurt by an April cyberattack, costing it between $10 million and $15 million. The maker of teeth-straightening systems said it successfully blocked the attack and restored its systems to normal. The stock lost 9.2% in the premarket. (Disclosure: NBC Nightly News investigated SmileDirectClub's customer complaints in February. The company accused NBCUniversal of publishing false information about the company and is seeking $2.85 billion for defamation.)
