Is NSP Stock Worth Buying After Its Strong Six-Month Rally in 2026?

Read MoreHide Full Article

Key Takeaways

  • NSP shares surged 30.9% in six months, moving closer to their 52-week high of $57.22.
  • Insperity's adjusted EPS rose 31%, while adjusted EBITDA climbed 13% to $36 million.
  • NSP's 49.04 EV/EBITDA ratio, heavy leverage and negative operating cash flow constrain upside.

Insperity, Inc. (NSP - Free Report) has rebounded sharply in 2026, but the recovery has not removed the debate around the stock. Better quarterly profitability, a high dividend yield and favorable growth scores support the bull case.

The offset is just as clear. Valuation has expanded, leverage remains elevated and cash-flow performance is still weak, making fresh upside harder to justify after the rally.

NSP's Rally Has Changed the Risk-Reward

NSP shares have gained 30.9% in the past six months and 28.8% over the trailing 12 months. That move has repaired much of the prior damage and pushed the stock closer to its 52-week high of $57.22.

The stronger price raises the burden of proof. Insperity is still rebuilding margins while average paid worksite employees declined 1% year over year in the second quarter to 305,764. In the broader employer-services space, Automatic Data Processing, Inc. (ADP - Free Report) and Paychex, Inc. (PAYX - Free Report) remain relevant comparisons because both offer payroll, human resources outsourcing and professional employer organization services.

Insperity's Valuation Looks Stretched

NSP trades at a trailing enterprise value-to-EBITDA ratio of 49.04, well above the sub-industry’s 8.61 and its own five-year median of 15.36. That gap signals that the recent rally has already priced in a large portion of the recovery narrative.

The $57 price target also leaves limited room from the reported share price of $54.03. For investors considering a new position, valuation is now one of the clearest constraints.

NSP's Earnings Recovery Offers Support

Insperity reported second-quarter adjusted earnings of 34 cents per share, up 31% year over year and 3% above expectations. Adjusted EBITDA increased 13% to $36 million, helped by pricing actions, benefit-plan changes and expense control.

Management now expects 2026 adjusted earnings of $1.88 to $2.43 per share, implying a sharp year-over-year recovery. The range is wide, however, and the full-year worksite-employee outlook still calls for a 1.6% to 1% decline.

Insperity's Income Appeal Adds a Cushion

The stock offers an annualized dividend of $2.40 per share, translating into a 4.4% yield. That income stream gives investors some cushion while the operating recovery unfolds.

Insperity also has a history of repurchases, but buyback spending has moderated. The company repurchased about 172,000 shares for $4 million in the first six months of 2026, while dividends totaled $46 million, underscoring that capital returns must be balanced against liquidity, borrowing and reinvestment needs.

NSP's Balance Sheet Tempers Upside

Leverage remains a central risk. NSP carries a debt-to-equity ratio of 6.87 and a debt-to-capital ratio of 87.29%, while borrowings under its credit facility stood at $420 million at the end of the second quarter.

Liquidity is not the main concern. Current assets of $1.77 billion exceeded current liabilities of $1.59 billion, and adjusted cash, cash equivalents and marketable securities increased to $95 million from $36 million sequentially. Still, net cash used in operating activities was $19 million in the first six months of 2026, keeping cash-flow quality in focus.

NSP's Scores Point to a Selective Setup

The bottom line is that NSP looks more suitable for patient investors seeking income and a recovery story than for those demanding clean valuation support. The rally has improved sentiment, but it has also reduced the margin of safety.

The stock currently carries a Zacks Rank #3 (Hold). You can see the complete list of today’s Zacks #1 Rank (Strong Buy) stocks here.

Its VGM Score of A and Growth Score of A point to favorable combined and growth characteristics, while the Value Score of B is constructive. The Momentum Score of D is the outlier and supports a wait-and-see approach rather than an aggressive buying stance.
