Cash Flow from Investing
CFI is the cash a company spends on (or gets back from) long-term assets: capex, acquisitions, and buying/selling investments. It's normally negative for a growing company because it's reinvesting. Big positive CFI usually means the company sold assets.
Definition
Cash flow from investing activities (CFI) is the second section of the cash flow statement and records the cash a company spends on or receives from long-term assets and investments — most importantly capital expenditures, acquisitions, and the purchase or sale of securities. For a healthy growing company CFI is usually negative because the firm is reinvesting in property, plant, equipment, and bolt-on deals; large positive CFI often signals asset sales or divestitures, which warrant a closer look.
Formula
CFI = − Capital Expenditures − Acquisitions + Proceeds from Asset/Investment Sales ± Net Purchases of Securities
Capital Expenditures
Cash spent on PP&E; the largest and most recurring outflow
Acquisitions (net of cash acquired)
Cash paid to buy other businesses; outflow
Proceeds from Sales
Cash received from selling assets, divisions, or investments; inflow
Net Purchases of Securities
Buying (outflow) or selling (inflow) marketable securities and equity stakes
What flows through CFI
The investing section captures cash tied to long-lived assets and the investment portfolio: (1) CAPITAL EXPENDITURES — cash spent on property, plant, and equipment, almost always the largest line and a cash OUTFLOW; (2) ACQUISITIONS of other businesses, net of cash acquired (outflow), and proceeds from DIVESTITURES (inflow); (3) PURCHASES AND SALES OF INVESTMENTS — marketable securities, equity stakes, intangibles; (4) capitalized software or R&D where applicable. Note what is NOT here: interest received is sometimes in CFO, and anything financed with debt or equity belongs in financing, not investing — CFI is about deploying or recovering capital in productive assets, regardless of how it was funded.
Why CFI is usually negative — and when that's good
Negative CFI is normal and often healthy: it means the company is investing in its future via capex and M&A. The key analytical move is to compare capex to depreciation and amortization. Capex roughly equal to D&A suggests 'maintenance' spending that just replaces aging assets; capex well above D&A signals growth investment (new capacity, expansion). Capex persistently BELOW D&A can be a warning that a company is underinvesting and harvesting its asset base to flatter near-term cash flow. So CFI's magnitude and composition tell you whether management is building or starving the business.
CFI as a red-flag detector
Large or unusual CFI inflows deserve scrutiny. A company posting strong total cash flow only because it sold a division, liquidated investments, or sold and leased back its headquarters is not generating sustainable operating cash — that's a one-time event sitting in investing. Conversely, a serial acquirer will show big recurring outflows for acquisitions, which you must separate from organic capex when judging the underlying business. When building a model, isolate maintenance capex from growth capex and acquisitions so your free cash flow reflects the true cost of keeping the business running.
Worked Example — With Real Numbers
A company spends $80M on capex, pays $120M for a bolt-on acquisition (net of cash acquired), receives $25M from selling an old facility, and buys $40M of marketable securities. CFI = −$80M − $120M + $25M − $40M = −$215M. The deeply negative figure reflects a year of heavy reinvestment and M&A — not a problem if those investments earn returns above the cost of capital, but you'd flag that $120M acquisition as non-recurring when normalizing free cash flow.
Key Takeaways
CFI captures capex, acquisitions, divestitures, and purchases/sales of investments.
It's normally negative for growing companies because they reinvest capital.
Compare capex to D&A: above D&A = growth, below D&A = possible underinvestment.
Large positive CFI usually signals asset sales — often one-time, not sustainable.
Separate maintenance capex, growth capex, and acquisitions when modeling free cash flow.
Common Mistakes in Interviews
Including debt or equity raises in CFI — those belong in financing.
Treating proceeds from a one-time asset sale as recurring cash flow.
Ignoring the capex-vs-D&A comparison when judging reinvestment health.
Lumping acquisitions in with organic capex and overstating maintenance needs.
Forgetting acquisitions are reported net of cash acquired, not gross purchase price.
How Interviewers Test This
A common follow-up: 'A company's total cash flow is positive but operating cash flow is negative — how is that possible?' The answer usually lives in CFI or financing: it may have sold assets (CFI inflow) or raised debt/equity (financing inflow) to mask weak operations. Always trace which section is doing the work.
