Under the terms of the deal, which has been approved by both company's boards, investors will receive 0.592 shares of Teladoc Health plus $11.33 in cash for each share of Livongo they hold.
Last week, Teladoc Health reported that its second-quarter revenue had leaped by 85% year over year to $241 million; Livongo's revenues have been rising even faster.
In Q2, Livongo's total revenue soared 125% year over year to $91.9 million, which was $5.2 million more than analysts' consensus expectation.
The combined new virtual care Goliath is expected to report $1.3 billion in total revenue this year, with adjusted earnings of $120 million.
