Breaking: Elliott Advisors has offered to buy AthenaHealth for between $155-$160 per share in cash, per CNBC's David Faber. That's at least a 23% premium on Friday's closing price, representing a market value of between $6.26 and $6.4 billion.

• Elliott last year acquired a 9.2% stake in AthenaHealth, saying it was open to a variety of changes (including management shakeups or a company sale). AthenaHealth profits have since improved.
• The healthcare software company is led by founder and CEO Jonathan Bush, cousin of George W. and Jeb.
• Leaving aside the strategic specifics here, it's yet another indication that Elliott is no longer satisfied being an activist investor. It wants to be an owner.

• Investor and board member Paul Maeder: "The two worst things to be as a startup is too early or too late. Too late you can't recover from, but you can survive too early if you have a great CEO and loyal investors."

Nestlé (SWX: NESN) has agreed to pay $7.15 billion in cash to Starbucks (Nasdaq: SBUX) for the right to sell the coffee company’s products in non-Starbucks shops around the world.

• Why it's the BFD: Because this is a major escalation in Nestlé's legalized stimulant battle with JAB Holding, which has seen Nestlé buy Blue Bottle and JAB purchase both Keurig Green Mountain, Douwe Egberts and Peet’s.
• Bottom line: "Coffee is popular with younger customers who have grown up with Starbucks. A willingness to pay up for exotic beans and specialty drinks means companies can brew up richer profit margins than in mainstream packaged food." — Reuters
