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

Same yardstick, side by side (as of September 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: NGVT 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. NGVT 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 NGVT 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.

Ingevity Corporation is a South Carolina-based specialty chemicals maker that was spun off from WestRock in 2016. It operates through three segments: Performance Materials, which engineers activated carbon for automotive gasoline vapor emission control canisters (where Ingevity holds an estimated 80 to 85 percent global share and earns EBITDA margins above 50 percent); Performance Chemicals, centered on pavement and road technologies plus industrial specialties; and Advanced Polymer Technologies, which makes caprolactone-based specialty polymers for coatings, adhesives, elastomers, and medical uses.

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.

• NGVT drivers: Dominant, high-margin emissions carbon; Portfolio repositioning toward higher quality.
• 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: The largest structural risk is electric vehicle adoption, since EVs eliminate the gasoline vapor demand that drives Ingevity's most profitable business, making Performance Materials concentration a double-edged sword. 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 NGVT 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 NGVT and SOLS guides.

NGVT. Trailing GAAP EPS has been negative due to prior impairments and charges, so the market leans on forward and adjusted metrics, with a forward P/E in the high-single to mid-teens depending on the estimate. Q1 2026 revenue rose about 4 percent year over year to roughly $258 million with adjusted EPS of $1.15, driven by pricing in Performance Materials and pavement technologies. The story is more about margin quality, deleveraging, and portfolio simplification than top-line growth.

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, JULY 2026): NGVT shows revenue (ttm) ~$1.3B, 2026 sales guidance ~$1.05-1.15B, 2026 adj. ebitda guidance ~$370-395M, 2026 adj. eps guidance ~$4.70-5.20; SOLS shows market cap ~$10.8B, revenue (ttm) ~$3.98B, net income (ttm) ~$188M, fy2025 adj. standalone ebitda ~$957M.

NGVT 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.
