What happened

Shares of Exact Sciences (EXAS 0.10%) stormed higher by 16.5% over the first three and a half days of trading this week, according to data provided by S&P Global Market Intelligence. The big gain came after the biotech posted better-than-expected first-quarter earnings on Tuesday, May 9

Highlights from the report included a 24% rise in quarterly revenue to $602 million (relative to the same period a year ago), driven by an uptick in sales for its flagship cancer diagnostic, Cologuard; a net loss that shrank by an impressive 58% on a year-over-year basis; and a strong cash position that totaled $421.4 million at the end of the period. The cancer diagnostic specialist also raised its 2023 full-year revenue guidance by a noteworthy $110 million at the midpoint. 

So what

After posting these impressive Q1 results, Exact Sciences quickly won a series of price target upgrades from various Wall Street analysts. The bulk of analysts covering the stock now view it as moderately undervalued at current levels. Underscoring this point, Wall Street's consensus 12-month price target on Exact's shares implies upside potential of approximately 8%. Exact's stock has already risen by a staggering 57% so far this year.

Now what

Is Exact's stock a buy in the wake of its latest financial update? Although the biotech is still losing money, the strong commercial momentum of Cologuard should change this situation for the better soon. In fact, management now expects the company to be cash-flow-positive at some point this year. That's a favorable improvement over the company's prior forecast of becoming cash-flow-positive in 2024. With a brightening outlook and a proven revenue generator in Cologuard, Exact's stock may indeed be worth buying right now.
