SAP vs WK: Which Is the Better Buy in 2026?
Last updated August 2026
Short answer
SAP is the larger of the two ($211.93B market cap): the incumbent the market prices for continued execution (19.13x forward earnings, beta 0.74). WK is the smaller challenger ($4.17B), priced similarly on forward earnings (18.35x): more room to run, but more to prove. The real question is which set of drivers you believe, and whether owning one (or both) leaves you over-concentrated.
SAP vs WK: the tie-breaker metrics
Same yardstick, side by side (as of August 2026). Valuation lined up like this is most meaningful for two names in the same corner of the market, which these are. Figures are approximate; verify before investing.
| Metric | SAP | WK | What it tells you |
|---|---|---|---|
| Market cap | $211.93B | $4.17B | Size. The larger name is the incumbent; the smaller has more room to grow and more to prove. |
| Forward P/E | 19.13 | 18.35 | Valuation on next year's expected earnings, the same yardstick for both. Lower is cheaper for that growth; higher means the market is paying up. |
| Trailing P/E | 23.97 | 89.52 | Valuation on the last 12 months. A big drop from trailing to forward means the market expects earnings to jump, so more growth is already in the price. |
| Beta | 0.74 | 0.44 | Volatility vs the market. Above 1 swings harder than the index; below 1 is steadier. Higher beta means bigger drawdowns to hold through. |
| Price vs 52-week range | 25% of range | 58% of range | Where today's price sits between the 52-week low and high. Near the high is momentum with less margin of safety; near the low is out of favor or a discount, depending on why. |
Before you buy: how SAP and WK affect your concentration
The metrics above tell you which is the marginally better business. The bigger risk for most people is not picking the slightly worse stock, it is over-concentrating. SAP and WK share themes, so owning both, or adding either to what you already hold, can quietly push a large share of your portfolio into one bet.
This is the part a generic comparison page cannot answer, because it depends on what you own. Connect your brokerage and Walnut shows your real, combined SAP and WK exposure, flags overlap with your existing positions, and tells you if adding one would tip you past a concentration you are comfortable with, read-only by default, with your login staying at your broker.

What does SAP SE (SAP) do?
SAP SE is a German enterprise-software company and one of the world's largest ERP providers, whose systems form the operational backbone of many of the biggest corporations and public-sector organizations. Its products span finance, supply chain, procurement, human resources, spend management, and analytics, anchored by the S/4HANA ERP suite and delivered increasingly as cloud services. US investors typically access SAP through its NYSE-listed ADR under the ticker SAP; the underlying ordinary shares trade in Frankfurt.
What does Workiva Inc. (WK) do?
Workiva (NYSE: WK) sells a single cloud platform for regulated reporting. Finance, audit, risk and sustainability teams pull figures from their ERP, general ledger and other systems, assemble documents that stay linked back to those sources, and file the result with regulators. The original wedge was SEC filings and XBRL tagging, where changing one number has to flow through every table and footnote that uses it. From there the company added SOX and internal controls, statutory reporting, ESEF filings in Europe, and sustainability disclosure. Around 92% of revenue is subscription and support, spread across roughly 6,750 customer organizations including a large share of the Fortune 500.
SAP vs WK: how do they differ?
Both fit overlapping themes, but they are not interchangeable. The useful comparison is which set of drivers and risks you want exposure to.
- SAP drivers: Cloud transition and recurring revenue; Cloud ERP Suite momentum.
- WK drivers: Large accounts, not logo count; The margin turn arrived a year early.
Which fits which kind of investor
A faster-growing, richer-valued name usually swings harder, so it suits a longer horizon and a higher tolerance for volatility; a steadier, more cash-generative business suits a more conservative or income-minded investor. The honest test is which set of risks you could hold through a drawdown: The main risk is expectations: SAP trades as a high-quality compounder, so a slowdown in cloud growth, backlog, or margin progress could weigh on a valuation that already prices in successful execution. For WK, european scope is the clearest risk.
SAP or WK: which should you pick?
Growth-minded investors who believe the theme has years to run tend to accept the richer multiple for more upside; value-minded investors lean toward the cheaper forward earnings and steadier profile. Pick SAP if you believe its drivers more; WK if you believe its. Many investors hold both, but since they share themes, that is a concentrated bet, not diversification. Decide deliberately and check overlap. For the full detail, see the SAP and WK guides.
SAP vs WK: the full fundamentals
SAP. Figures are approximate, reported in euros, and tied to the asOf date; verify live numbers before acting. SAP typically trades at a premium software valuation that reflects its entrenched ERP position and improving cloud economics, so the earnings multiple leans on continued cloud growth and margin expansion. Because it is an ADR, US-dollar returns also depend on the euro-dollar exchange rate, which can add or subtract from the underlying business performance.
WK. At ~$74 a share the market value is ~$4.17B. Netting out ~$815M of cash and adding back ~$773M of converts puts enterprise value near ~$4.1B, roughly 4x the ~$1.04B of revenue guided for 2026 and about 19x the free cash flow that a ~21% margin implies. Software growing in the high teens with cash margins near 20% carried far richer multiples in 2021; the market now pays for steady compounding rather than acceleration, and Workiva is priced accordingly.
Headline figures (approximate, Jul 2026): SAP shows total revenue (q1 2026) ~9.6 billion euros, up ~12% at constant currencies, cloud revenue (q1 2026) ~5 billion euros, up ~27% at constant currencies, current cloud backlog ~22 billion euros, up ~25% at constant currencies, cloud erp suite growth Growing faster than overall cloud (reported around 30%+ range); WK shows revenue (ttm) ~$966M, q2 2026 revenue growth ~19% year over year, subscription also ~19%, non-gaap operating margin (q2 2026) ~16.8%, up from ~3.8%, 2026 free cash flow margin guidance ~21% on ~$1.04B of revenue.

FAQ
What is the difference between SAP and WK?
+
SAP SE is a German enterprise-software company and one of the world's largest ERP providers, whose systems form the operational backbone of many of the biggest corporations and public-sector organizations. Workiva (NYSE: WK) sells a single cloud platform for regulated reporting. They show up together because they share investment themes, but they are different businesses, so the better fit depends on which thesis you are expressing.
Is SAP or WK the better stock?
+
Neither is universally better. SAP is the larger incumbent; WK is the smaller challenger and looks cheaper on forward earnings. Walnut is informational, not investment advice. Compare what each does, the tie-breaker metrics above, and the risks, then decide which fits your thesis and what you already own.
Which is cheaper, SAP or WK?
+
On forward P/E (as of August 2026), SAP trades at 19.13x and WK at 18.35x, so WK is the cheaper of the two on next year's expected earnings. A lower multiple is not automatically the better buy: a richer valuation can be justified by faster growth, and a lower one can reflect real risk. Weigh the multiple against how fast each business is compounding.
Should you own both SAP and WK?
+
Because they share themes, owning both concentrates you in that theme. That can be intentional (a focused bet) or accidental (less diversification than it looks). Walnut can show your combined exposure across both, and whether adding either over-concentrates you, before you buy.
What are the risks of SAP vs WK?
+
SAP: The main risk is expectations: SAP trades as a high-quality compounder, so a slowdown in cloud growth, backlog, or margin progress could weigh on a valuation that already prices in successful execution. Macroeconomic softness can delay large enterprise IT projects and ERP migrations, which are big, multi-year commitments. Competition is strong across ERP and adjacent categories from Oracle, Microsoft, Workday, and Salesforce, and cloud-native rivals can pressure specific modules. As an ADR, SAP also carries currency risk, since results are reported in euros and translated into dollars, so a stronger dollar can reduce reported growth for US investors. Finally, the payoff from Business AI is still being proven, and heavy AI and cloud investment must translate into durable monetization rather than just added cost. WK: European scope is the clearest risk. Directive (EU) 2026/470 raised CSRD thresholds to roughly 1,000 employees and EUR 450M of turnover and fully exempted listed SMEs, which removes a large slice of the mandated buyers the sustainability products were sized for. Competition arrives from two directions at once: disclosure specialists that undercut on the filing piece, and close and controls platforms expanding toward reporting. The ~$773M of convertible notes sits against ~$815M of cash and securities, so the balance sheet is comfortable, though conversion becomes a dilution question at higher share prices. Retention around 111% is decent but below what the stock was once valued on, and with customer count growing about 4% there is little new-logo volume to offset a further slip. Platform consolidation deals take a long time to close, so a budget freeze shows up as delayed expansions rather than churn, which makes it slow to detect.
