ENTG vs SOLS: Which Is the Better Buy in 2026?

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.

Reading it: SOLS 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. ENTG and SOLS 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 ENTG and SOLS 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.

Entegris is a specialty supplier to the semiconductor industry, focused on materials handling, filtration, and high-purity process chemistries. The company's products are used inside semiconductor fabs to handle wafers and chemicals at extreme purity levels (parts per billion contamination matters). Specific product areas include wafer handling automation, gas filtration and purification, liquid chemical filtration and delivery, and specialty materials (advanced photoresist precursors, CMP slurries, etc.).

Solstice Advanced Materials is a Morris Plains, New Jersey specialty-chemicals company that began trading on Nasdaq on October 30, 2025 after being spun off from Honeywell. It runs two segments: Refrigerants and Applied Solutions (RAS), which sells low-global-warming-potential refrigerants, blowing agents, solvents and aerosol materials into HVAC/R, automotive, appliance and building end markets, and Electronic and Specialty Materials (ESM), which supplies electronic materials, industrial-grade fibers and life-sciences chemicals to semiconductor, defense, pharmaceutical and construction customers. Full-year 2025 net sales were about $3.9 billion with net income of roughly $237 million and adjusted standalone EBITDA near $957 million, a margin around 24.6%.

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

• ENTG drivers: Leading-edge process node growth; Consumables and recurring revenue model.
• SOLS drivers: Low-GWP refrigerant transition; Electronics and AI-infrastructure exposure.

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: Semiconductor capex cycles affect Entegris though less severely than equipment makers (consumables persist through utilization downturns). For SOLS, the planned $14.5 billion Element Solutions acquisition adds substantial debt through a $4.7 billion bridge facility, raising integration and balance-sheet risk, and it is not expected to close until the first half of 2027 subject to regulatory approvals.

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 ENTG if you believe its drivers more; SOLS 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 ENTG and SOLS guides.

ENTG. Entegris trades at a premium reflecting the high-quality recurring revenue model and the leading-edge growth story. The valuation has compressed and re-expanded with the semiconductor cycle; current multiple is supported by AI-driven fab capex.

SOLS. SOLS trades at a high trailing earnings multiple, reflecting a low trailing net income figure and expectations tied to its refrigerant franchise and electronics push. Management's 2026 guidance points to net sales of about $3.9 to $4.1 billion and adjusted diluted EPS of roughly $2.45 to $2.75. The pending Element Solutions acquisition would materially change the size and capital structure of the company if it closes.

Headline figures (approximate, early 2026): ENTG shows revenue (ttm) ~$3.5 billion, operating margin ~20% (improving as CMC integration completes), net income (ttm) ~$400 million, eps (ttm) ~$2.70; SOLS shows market cap ~$10.8B, revenue (ttm) ~$3.98B, net income (ttm) ~$188M, fy2025 adj. standalone ebitda ~$957M.

ENTG and SOLS 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.
