TAC vs UAVS: 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.

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. TAC and UAVS 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 TAC and UAVS 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. Walnut is not an investment adviser.

TransAlta Corporation is one of Canada's largest publicly traded power generators, owning and operating a diversified fleet across Canada, the United States, and Western Australia. Its portfolio spans hydro, wind, solar, battery storage, and natural-gas generation, organized into four generating segments (Hydro, Wind and Solar, Gas, and Energy Transition) plus Energy Marketing and Corporate. Roughly 61 percent of generating capacity sits in Alberta, where much of the fleet is exposed to the merchant market, so results move with Alberta power prices, hedging levels, and plant availability. The company has been reshaping its fleet through moves like the Heartland Generation acquisition (1,747 MW of flexible Alberta capacity), converting Centralia Unit 2 from coal to gas, and a C$95 million Far North acquisition adding 310 MW in Ontario.

AgEagle Aerial Systems designs and sells professional-grade autonomous uncrewed aerial systems for defense, public safety, surveying and mapping, agriculture, and utilities. What makes it unusual for a company its size is that it owns the whole stack: the eBee fixed-wing drones, the MicaSense multispectral sensors that ride on them, and the Ground Control planning and mapping software that ties the data together. Management has been steering toward higher-margin defense and security products, especially the eBee VISION and eBee TAC, which are built for tactical missions. Recent wins include a 15-drone eBee VISION order from a US Army unit in Europe, additional Army training and integration buys, a five-year GSA contract, and a collaboration with Wingtra, all of which put its hardware into real military and government workflows.

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

• TAC drivers: Alberta merchant power exposure; Clean-energy and fleet transition.
• UAVS drivers: Full-stack drone integration; Pivot to higher-margin defense products.

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: TransAlta's biggest risk is its heavy exposure to volatile Alberta merchant power prices, which drove Q1 2026 revenue and EBITDA sharply lower year over year. For UAVS, the overriding risk is that this is a speculative micro-cap with a long history of losses and repeated shareholder dilution, so even good product news can be offset by new share issuance.

Pick TAC if you believe its drivers more; UAVS 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 TAC and UAVS guides.

TAC. TransAlta reaffirmed its 2026 outlook after a softer first quarter driven by lower Alberta power prices and no generation at Centralia Unit 2. The company reports in Canadian dollars and emphasizes adjusted EBITDA and free cash flow, since reported GAAP net earnings can be volatile and trailing-twelve-month figures have shown net losses. Liquidity stood at roughly C$1.5 billion.

UAVS. These figures are approximate, tied to the asOf date, and drawn from recent reports; verify live numbers in the latest SEC filings before acting. For a pre-profit micro-cap like AgEagle, standard valuation multiples are largely meaningless because there are no stable earnings to anchor them. The stock moves on order announcements, cash runway, dilution, and listing-compliance headlines far more than on any earnings multiple, so position sizing and risk tolerance matter more than a target price.

Headline figures (approximate, JULY 2026): TAC shows revenue (ttm) ~C$1.8 billion, q1 2026 revenue ~C$565 million (down from ~C$758 million), q1 2026 adjusted ebitda ~C$204 million (down from ~C$270 million), 2026 adjusted ebitda guidance ~C$950 million to C$1,050 million; UAVS shows business stage Speculative, unprofitable micro-cap; revenue modest and lumpy, driven by defense and government drone orders, fiscal 2025 net loss Roughly $5.3 million, down about 85% from around $35 million in 2024 (verify latest filings), cash position Around $29.9 million reported for fiscal 2025 after late-2025 raises and debt restructuring; cash burn remains a watch item, gross margin Improved to roughly 52% in fiscal 2025 from about 47%, helped by mix shift to defense products.

TAC and UAVS 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. Walnut can show your combined TAC and UAVS exposure against your real portfolio. It is not an investment adviser.
