Quick Read

Caterpillar returned 1,125% over 10 years versus Coca-Cola's 184%, making it the stronger Roth IRA compounder despite its lower 0.8% yield.
Coca-Cola yields 2.4%, which is roughly three times Caterpillar's payout, making it the better fit for income-focused retirees already in the withdrawal phase.
Caterpillar's 8% dividend raise marks its sixth straight year of high single-digit increases, backed by a $72 billion backlog in data-center demand.

For a Roth IRA investor considering blue-chip Dividend Aristocrats, the question may come down to whether Caterpillar (NYSE:CAT) or Coca-Cola (NYSE:KO) belongs in a tax-free account built to compound for decades. Both have raised their quarterly payout in each of the past several years, with no cut and no freeze anywhere in the recent record, so payment reliability is comparable between them. The separation lies in a clean trade-off: Coca-Cola pays a meaningfully higher yield on a much steadier share price, while Caterpillar has grown its dollar payout faster and delivered far superior total return across every long window.

24/7 Wall St.

A Dividend Aristocrat is an S&P 500 member with a multi-decade record of annual dividend increases, and that record is what retirement investors are actually buying: evidence that management will keep prioritizing the payout across cycles.

Friday morning, Caterpillar traded at $805.93, up 0.9% from the prior close, while Coca-Cola traded at $87.80, down 0.3%. Year to date, Caterpillar is up 41.6% versus Coca-Cola's 28.0%.

Income: Coca-Cola Wins Cleanly

Coca-Cola yields 2.4% on a forward annualized payout of $2.12 per share, with the next $0.53 quarterly distribution scheduled for October 1, 2026. Caterpillar yields just 0.8% on a forward annualized payout of $6.52. Coverage is comfortable at both: Coca-Cola's 2025 operating cash flow of $7.41 billion against an $8.78 billion dividend payout was distorted by working-capital timing, and Q2 2026 operating cash flow rebounded to $5.52 billion. Caterpillar generated $5.1 billion in MP&E free cash flow last quarter alone. For a retiree buying income today, Coca-Cola pays roughly three times the yield on a lower-beta stock.

Dividend Growth and Total Return: Caterpillar Wins Decisively

Caterpillar just raised its quarterly dividend to $1.63 from $1.51, an 8% increase announced in June that management called its sixth consecutive year with a high single-digit quarterly increase. Coca-Cola stepped up to $0.53 from $0.51 earlier this year. The dollar-growth trajectory favors Caterpillar.

The total-return gap is wider still. Over one year, Caterpillar returned 80.5% versus Coca-Cola's 34.5%. Over five years, its 339.7% versus 86.7%, respectively, and over ten years, 1,125.14% versus 184.37%. The staple that income investors reflexively hold for compounding has substantially lagged the cyclical industrial across every long window.

Valuation, Risk, and Current Setup: Split, Edge to Coca-Cola

Caterpillar trades at a trailing PE of 35 and a forward PE of 24, with a beta of 1.59. Coca-Cola trades at a trailing PE of 26, forward PE of 25, and a beta of 0.34. Analyst targets imply upside to $975.61 for Caterpillar and $94.70 on Coca-Cola.

Recent price action favors Coca-Cola, which is down 1.0% over the past month while Caterpillar is off 3.9%. Caterpillar's earnings and payout growth hinge on a capital-spending cycle now anchored to data-center power demand and a $72 billion backlog. Coca-Cola's rest on steadier consumer demand. Inside a long-dated account, that cyclicality is a genuine risk. Coca-Cola comes out on top for its stability and entry price.

Why the Roth Wrapper Matters Here

Both companies pay qualified dividends that already receive preferential treatment in a taxable account, so the Roth case here rests on decades of reinvested dividends compounding with no annual tax drag and no tax on qualified withdrawals. So, the choice collapses into which combination of payout stream and price appreciation produces the larger ending balance.

Therefore, Caterpillar earns its spot in a Roth IRA. The ten-year return gap is too large to hand-wave, the dollar-dividend growth is faster, and the backlog offers unusual visibility for a cyclical, with management saying "no one is slowing down at the moment" on data-center power orders. Coca-Cola better fits an income-focused retiree already in the withdrawal phase, or a taxable account where the higher qualified yield funds current spending. Younger Roth investors with a horizon long enough to absorb an industrial downturn may find Caterpillar the better fit.
