Growth momentum hasn't disappeared — it's just migrated. As capital rotates out of broad cyclicals, a smaller cluster of names continues to compound quietly beneath the surface. A fresh screen through FMP's Income Statement API highlights five such companies converting steady revenue traction into expanding EBITDA and structural margin lift.

This isn't a story of rebound; it's one of persistence — where the math of multi-year compounding still holds even as sentiment fades elsewhere.

Five Companies Showing Durable Growth Momentum

GFI Gold Fields Limited

5-Year Revenue CAGR: 12.84%
5-Year EBITDA CAGR: 18.45%

Gold Fields' 5-year revenue and EBITDA growth (12.84% and 18.45%, respectively) point to more than simple gold-price exposure: they reflect portfolio optimisation and operating leverage kicking in. For example, H1 2025 delivered strong free-cash-flow and the final dividend was increased as volumes at Salares Norte bestride weather headwinds. The key signal here is not just rising ounces, but rising margins — the company is converting incremental production into disproportionately large bottom-line gains.

What to watch: the next quarterly cost-per-ounce metrics and whether the South Deep turnaround continues to track timeline; if unit costs hold while output expands, the margin compression risk shrinks.

STRL Sterling Infrastructure, Inc.

5-Year Revenue CAGR: 16.55%
5-Year EBITDA CAGR: 38.34%

Sterling Infrastructure's growth pattern — 16.55% revenue, 38.34% EBITDA — signals a business increasingly dominated by higher-margin segments such as large data-centre builds and advanced infrastructure. Recently, the company raised its full-year guidance based on a stronger backlog of mission-critical projects and operating-margin improvement. That gap between top-line and profit growth suggests two things: backlog quality is improving, and cost structure is being leveraged. Investors should focus on project phasing and backlog conversion rates: if bookings turn into revenue and margins hold, the strength is real. Conversely, any sign of margin erosion or project delays would undermine the current profile.

To deepen the analysis, segment disclosures (project-type revenue and margin by segment) help clarify where the margin improvement is coming from, while backlog and bookings metrics offer forward looks into delivery risk.

DRD DRDGOLD Limited

5-Year Revenue CAGR: 16.16%
5-Year EBITDA CAGR: 47.31%

DRDGOLD's dramatic EBITDA CAGR (47.31%) versus its revenue CAGR (16.16%) embodies a classic low-capex tailings-recovery story: incremental tonnes come with lower marginal cost, enhancing profits faster than sales. The company's dividend key-figure recently doubled, signalling confidence in sustained cash conversion.

What matters here is throughput reliability and cost discipline: power supply, plant uptime and grade stability are the levers that move EBITDA rapidly. A watchpoint: if one of these operational variables falters (for example, Eskom load-shedding impacts), the outsized margin gain may reverse. On the upside, sustained throughput and stable grades suggest the current growth signal is structural rather than cyclical.

To validate this thesis, combining income-statement growth with production and cost-per-unit operational metrics offers clarity, while cash-flow and dividend disclosures reveal how much of that EBITDA is being realised as shareholder value.

RTX RTX Corporation

5-Year Revenue CAGR: 13.35%
5-Year EBITDA CAGR: 20.03%

RTX's growth — 13.35% revenue CAGR and 20.03% EBITDA CAGR — reflects a subtle but important mix shift: defense and aftermarket parts are growing faster than commercial aviation services, and cost efficiency has improved despite supplier disruptions. In its recent quarter, back-to-back double-digit sales and margin beats point to a resilient franchise.

Key signal: if aftermarket growth accelerates and defence orders hold, RTX could maintain the margin premium. Items to monitor: certification and integration progress of new engine programmes (which could reset cost curves), and whether margin expansion persists when commercial aviation remains under pressure.

Here, segment-level results (aerospace vs. defence vs. aftermarket) help identify where growth is happening, while backlog disclosures and certification milestones act as leading indicators of margin progression.

B Barrick Mining Corporation

5-Year Revenue CAGR: 6.57%
5-Year EBITDA CAGR: 10.48%

Barrick's more modest growth (6.57% revenue, 10.48% EBITDA) belies a longer-term repositioning: the company is increasingly investing in copper and scaling out long-life projects that redefine its future cash flow profile. Recent announcements around the Lumwana expansion and the progress at Reko Diq signal that the growth driver is shifting from near-term gold production to multi-decade copper-gold assets. The current EBITDA growth thus reflects near-term conversion, but the real signal lies in reserve and resource expansion, capex discipline and execution of large mines.

What to watch: whether the copper exposure becomes a larger part of the narrative, and how capital-expenditure phasing impacts free-cash-flow in the medium term.

For deeper insight, complement income-statement growth with project technical reports and reserve updates, and overlay those with commodity-price sensitivity or analyst target-changes to understand how the market is starting to price in the new portfolio tilt.

Decoding the Shape of Sustained Growth

Across these five companies, a clear signal emerges: sustainable growth today is less about expanding scale and more about how efficiently that scale converts into margin and cash. Gold Fields and DRDGOLD are leveraging operational discipline to deepen profitability without chasing volume. Sterling's infrastructure mix is yielding outsized EBITDA leverage. RTX continues to extract resilience from its backlog, while Barrick is reshaping its portfolio toward copper-led longevity. The through line is consistency — compounding driven by internal productivity, not external cycles.

CAGR shows speed, but not endurance. When revenue and EBITDA trajectories are read alongside free-cash-flow behavior and balance-sheet stability, the difference between momentum and structural compounding becomes visible. Companies that grow earnings and cash flow in sync — without expanding leverage — are the ones reinforcing efficiency rather than just expansion.

That's where multi-period data from FMP's Statements APIs, cross-checked against cash-flow progression, becomes especially useful. The relationship between margin expansion and free cash flow is often misunderstood — strong earnings can mask liquidity strain if capital intensity rises. The reference guide on understanding cash flow offers a clear framework for distinguishing real efficiency from accounting lift, and that same logic applies here.

When those layers — income, balance sheet, and ratio data visible on the FMP Homepage — align in direction and consistency, the curve isn't just steep; it's durable.

Setting Up a Clean CAGR Workflow with FMP API

Setting up a recurring CAGR screen doesn't require a spreadsheet — you can do it entirely through structured pulls from FMP's Income Statement endpoints. The process is straightforward once the logic is clear.

Step 1: Pull Income Statement Data

Begin with a single-company query using the standard Income Statement API. This gives you all the reported periods you'll need for the base calculation.

Endpoint:
https://financialmodelingprep.com/stable/income-statement?symbol=AAPL&apikey=YOUR_API_KEY

Step 2: Gather Historical Figures

From the JSON output, extract sequential periods of revenue, EBITDA, or EPS — whichever metric you want to track. Arrange these values chronologically to create a continuous time series.

Step 3: Calculate CAGR

With the first and last values in hand, apply the formula across the number of years in the series:

Formula:
CAGR = (Ending Value / Beginning Value)^(1 / Years) - 1

This step normalizes the growth rate, turning uneven year-to-year movement into a clean annualized figure that reflects the real pace of expansion.

Step 4: Scale Screening with Bulk API

After confirming that the calculation works for one ticker, extend it across a broader universe by calling the Income Statement Bulk API:
https://financialmodelingprep.com/stable/income-statement-bulk?year=2025&period=FY&apikey=YOUR_API_KEY

Running your growth logic at this level allows you to screen by thresholds (for instance, all companies with five-year revenue CAGR above a chosen cutoff) and rank them by complementary metrics. The result is a fully repeatable workflow — a data-driven growth screen you can refresh and adjust programmatically without manual cleanup.

Scaling the Screen to Wider Coverage

The most practical way to scale this workflow is to start small, validate the logic, and then widen the data window. The Basic plan provides enough access to test your Income Statement pulls on a limited ticker set and confirm the calculations behave as expected.

Once the workflow is stable, upgrading to the Starter tier unlocks full U.S. equity coverage — the point where screening becomes meaningfully broad and repeatable. For multi-region comparison or longer historical depth, the Premium plan extends access across global exchanges and additional reporting years, letting the same growth logic operate at institutional scale.

Turning Data Trends Into Forward Signals

When built into a consistent screen, CAGR stops being a backward-looking metric and becomes an early signal of scalable efficiency. Automating the pull through FMP's Income Statement API and Income Statement Bulk API turns that pattern into something live — a way to spot where growth is compounding quietly before the market fully prices it in.
