Why it matters for Investors
Core earnings power: Shows how profitable the business is before financing and taxes.
Comparable across firms: Less distorted by capital structure or one-off items.
Driver of valuation: Feeds operating margin, EBITDA, and DCF models.

Formula

Practical considerations -
What’s “operating” (policy): Define what sits in COGS vs. R&D/S&M/G&A; apply consistently.
Exclude non-operating: Interest income/expense, FX, investment fair-value changes, and taxes stay out.
Stock comp & D&A: Included in OpEx/COGS under GAAP (EBITDA adds back D&A; “ex-SBC” is non-GAAP—label it).
Capitalized costs: Capitalized software/R&D reduces OpEx now; amortization hits later—be consistent and disclose.
Adjusted views: If you exclude one-offs (restructuring, impairments), label Adjusted Operating Income and reconcile.

Notes
Stay operating-only: No interest/tax/investment gains here.
Consistent classifications: Keep hosting, fulfillment, and delivery costs in COGS; salaries/tools in the right OpEx bucket.
If adjusted: Call it Adjusted Operating Income and bridge to GAAP.

Best Practices
Show both % and $: Operating Income and Operating Margin.
Bridge the delta: Price–volume–mix–cost–productivity explains QoQ/YoY moves.
Segment it: Product, region, and channel views to surface mix effects.
Reconcile adjustments: One-offs out? Disclose and reconcile to GAAP.

FAQs
Operating Income vs. EBIT?
EBIT = NI + Interest + Taxes; often equals Operating Income plus non-operating income. Operating Income excludes non-operating by design.Operating Income vs. EBITDA?
EBITDA = Operating Income + D&A (and sometimes other add-backs). It’s a non-GAAP cash-proxy; Operating Income is GAAP.Does stock-based comp sit in Operating Income?
Yes. SBC is recorded in OpEx/COGS; it reduces Operating Income (non-cash but real dilution).Where do restructuring/impairments go?
Usually operating. If you exclude them for “adjusted” results, label and reconcile.Can Operating Income be negative?
Yes—then it’s an operating loss (early stage, heavy R&D/S&M, or weak gross margin).Do interest income or FX gains count?
No—those are non-operating; keep them out.
