NSP vs TNET: Which Is the Better Buy in 2026?

Same yardstick, side by side (as of October 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.

Reading it: TNET is the cheaper of the two on forward earnings, but cheaper is not the same as better. Pair the valuation with growth (how far the forward P/E sits below the trailing P/E) and risk (beta) before you decide.

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. NSP and TNET 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 NSP and TNET 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.

Insperity is one of the largest professional employer organizations (PEOs) in the United States. Under a co-employment arrangement, a client business keeps running its operations while Insperity becomes the employer of record for payroll, payroll taxes, workers' compensation and, most importantly, health insurance, which it buys at scale through a large-group plan with UnitedHealthcare. Clients pay a bundled fee per worksite employee (WSEE), and because that fee includes the gross cost of wages and benefits, reported revenue of ~$6.9 billion over the trailing twelve months is far larger than the economic value Insperity keeps. The number that matters is gross profit, ~$0.9 billion in 2025, which is essentially the spread between what clients pay for benefits and services and what claims and insurance actually cost.

TriNet Group, Inc. (NYSE: TNET) is a professional employer organization that provides bundled human resources services to small and medium-sized businesses across the United States. Through a co-employment model, TriNet becomes the employer of record for its clients' worksite employees (WSEs), handling payroll processing and tax filing, health and other benefits administration, workers' compensation, and regulatory compliance, which lets small businesses offer large-company benefits without building an in-house HR department. Most of its reported revenue comes from insurance-related billings and administrative fees, and it also offers a lighter administrative services organization (ASO) option and an HR software platform. TriNet concentrates on higher-value verticals such as technology, professional services, financial services, and life sciences.

Both fit overlapping themes, but they are not interchangeable. The useful comparison is which set of drivers and risks you want exposure to.

• NSP drivers: Benefits pricing versus claim cost trend; HRScale and the Workday partnership.
• TNET drivers: Insurance cost ratio and margin discipline; Worksite employee (WSE) count stabilization.

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 central risk is health-care cost inflation. For TNET, triNet's revenue and margins are tightly linked to two volatile inputs: the number of worksite employees, which has been contracting, and healthcare claim costs, where an unexpected spike in medical utilization can compress the insurance cost ratio and hit earnings quickly (the company booked roughly a $1 million loss in Q4 2025 when claims ran high).

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 NSP if you believe its drivers more; TNET 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 NSP and TNET guides.

NSP. Headline revenue overstates Insperity's scale because it includes client payroll and benefit costs passed through the PEO, so the market cap of ~$2.05 billion looks tiny against ~$6.9 billion of sales. A fairer lens is enterprise value against adjusted EBITDA: at roughly ~$2.4 billion including credit facility debt, the stock trades near ~11x to ~13x the 2026 guidance range. That is a premium to its own depressed 2025 base but below where it traded before the claims shock. Forward P/E of ~23x assumes the recovery continues; the earnings base is still thin enough that small changes in claim trend swing EPS sharply.

TNET. TriNet's multiple has expanded in 2026 as two big earnings beats and a raised profit outlook offset a revenue line that is still shrinking. Note that reported revenue includes large insurance pass-through billings, so headline revenue (about 0.7 times sales) is much bigger than the net administrative and insurance margin the company actually keeps. Third-quarter results on October 29, 2026 carry a consensus of about $0.57 per share on roughly $1.18 billion in revenue, a seasonally weaker quarter for claims costs.

Headline figures (approximate, October 2026): NSP shows revenue (ttm) ~$6.9 billion (Q2 2026 ~$1.69 billion, up ~2% year over year), net income (ttm) ~-$16 million GAAP loss (Q2 2026 net income ~$4 million), adjusted eps (2026 guidance) ~$1.88 to ~$2.43 (2025 actual ~$1.03), adjusted ebitda (2026 guidance) ~$185 million to ~$225 million (2025 ~$131 million); TNET shows total revenue (ttm) ~$4.83 billion (FY2025 ~$5.0 billion), revenue growth (latest quarter) ~-4% YoY (Q2 2026 ~$1.18 billion), net income (ttm) ~$175 million; profit margin ~3.6%, q2 2026 adjusted eps ~$1.55 vs ~$0.93 consensus.

NSP and TNET are related but distinct: same themes, different businesses and risks. Neither wins in the abstract; the right pick is whichever thesis you actually believe, sized so you are not over-concentrated in one theme.
