Several companies have reported quarterly results over the past couple of days, and those offering testing for COVID-19 have seen impressive numbers. Standing out was San Diego-based Quidel Corp., whose numbers caught the attention of William Blair’s Brian Weinstein. Indeed, its $174.7 million in revenue far exceeded his organization’s estimate of $160 million, driven by influenza.

Palo Alto, Calif.-based Varian Medical Systems Inc. has joined the ranks of other companies in withdrawing its guidance even as at least one analyst saw positive news for the second quarter. For her part, BTIG’s Marie Thibault noted that the company missed on Americas oncology gross order metric, while falling short on consensus non-GAAP earnings per share (EPS) by five cents.

The restrictions on elective surgeries as hospitals struggle to manage the unfolding global pandemic are hitting medical device companies particularly hard. Abiomed Inc., which specializes in a tiny, minimally invasive heart pump to support heart failure patients, saw its first fiscal fourth-quarter revenue flatten as procedures were postponed. Still, U.S. revenue remained stronger than Wall Street had expected, even as ex-U.S. revenue had deeper declines.

Despite a drop off in elective procedures due to the COVID-19 pandemic, Stryker Corp., of Kalamazoo, Mich., unveiled first-quarter results that came in better than analysts had presumed. BTIG’s Ryan Zimmerman noted that, unlike other companies, Stryker did not pre-announce preliminary revenue. And while investors were concerned that the company would be adversely affected by the slump in elective procedures, "the diversity of the portfolio helped to offset procedure declines in late March.”

Hologic Inc., of Marlborough, Mass., is introducing another tool to help combat COVID-19, revealing the impending launch of a new Aptima molecular assay to detect the SARS-CoV-2 virus that will run on its Panther system. The company expects to be able to provide its lab customers with about 3 million Aptima tests next week. In addition, it anticipates producing about 1 million tests a week starting late next month.

Robotic-assisted surgical procedures have fallen off steeply as the ongoing global pandemic has unfolded, but the real impact on Intuitive Surgical Inc. will come as its hospital customers may have to limit orders for expensive equipment upgrades as they struggle to manage unprecedented financial burdens. The U.S. accounts for about 70% of its robotic surgery procedures, but by the last few weeks in March, that activity had been curtailed by roughly two-thirds.

Despite challenges associated with the ongoing COVID-19 pandemic, Abbott Laboratories saw its first-quarter revenue beating expectations, coming in at $7.73 billion vs. an expected $7.44 billion. Cowen’s Josh Jennings highlighted this result, adding in a note that while there are challenges for nondiabetes medical devices and core diagnostics, areas including diabetes, nutrition, the established pharmaceuticals division and COVID-19 testing shined.

Johnson & Johnson (J&J) managed to beat analyst earnings estimates due to unexpectedly strong first-quarter results in its consumer health and pharmaceutical businesses. But while those saw revenues climb in the double digits, its medical devices business declined by almost 5% due to deferred procedures. Wall Street rewarded the New Brunswick, N.J.-based company by driving its shares (NYSE:JNJ) up more than 5%. That’s even though the company also lowered its 2020 guidance.

Amid the COVID-19 pandemic, Genmark Diagnostics Inc., of Carlsbad, Calif., has offered a preliminary look at its first-quarter results. And it is forecasting hopeful news, increasing its full-year guidance to a range of $112 million to $122 million. That's up from a previous prediction of $100 million to $110 million.
