Shareholder: The company's current operations are time- proven successes.
Statements
Causal Moving into food services may siphon off funds for existing operations
Contrast Existing operations are time-proven successes.
Food services is risky, volatile, higher inherent risk.
Pharmaceuticals is less risky than food services.
Evaluate
The gist of this paragraph seems to be a rebuttal directed again a Plan.
The company is considering a Plan to move into food services, and the author is being negative about that. It might steal money we need for our existing, successful operations. Meanwhile it's volatile and riskier than other options we have for expanding (such as pharmaceuticals).
Goal
We might anticipate a safely-worded rebuttal like, "We shouldn't move into food services."
