With AT&T’s planned HQ move, what are downtown Dallas’ biggest employers?

AT&T announced plans to build a new global headquarters on 54 acres at 5400 Legacy Drive in Plano (the former EDS campus), targeting partial occupancy as early as the second half of 2028, while its lease at the 37‑story Whitacre Tower in downtown Dallas runs through Dec. 31, 2031. The move will remove one of downtown Dallas’s largest employers — prior reporting cited nearly 6,000 downtown staff in 2022 and the Dallas EDC estimates roughly 10,700 AT&T employees in the city — a shift that could pressure downtown office occupancy and local employment concentrations; Downtown Dallas Inc provided a roster of major downtown employers with headcount bands. Investors should monitor implications for Dallas commercial real estate fundamentals and corporate office demand timing tied to AT&T’s staged relocation.

Analysis

Market structure: AT&T’s planned move to a 54-acre Plano campus (partial occupancy H2 2028, lease at Whitacre Tower through 12/31/2031) shifts several thousand downtown office jobs—est. 4k–8k employees—out of the CBD, creating downward pressure on downtown office demand and likely adding 100–300 bps to local vacancy rates over 2–4 years. Winners: suburban landlords, Plano residential market and regional homebuilders; losers: downtown office landlords, retail/parking revenue and downtown-focused CMBS tranches.

Risk assessment: Near-term market impact is modest (days–weeks) because the lease runs to 2031; medium-term (6–24 months) risks include AT&T capex overruns, slower-than-expected leasing out of Whitacre Tower, or a sale that creates one-time balance-sheet effects. Tail risks include a broader corporate suburb-shift (multiple Fortune 500 relocations) materially re-pricing CBD office valuations and stress in Dallas muni revenue or local CMBS (low probability, high impact).

Trade implications: Tactical bias is underweight downtown office CRE and overweight suburban residential/landlord exposures. Direct plays: long select homebuilders (DHI, LEN) and short office/CMBS exposure (IYR or targeted CMBS indices); hedge via 3–12 month IYR puts. For AT&T (T), treat the move as neutral-to-mildly constructive long-term—use defined-risk options to express view while monitoring capex guidance.

Contrarian angles: Consensus may overstate permanent office obsolescence—Whitacre Tower remains leased to 2031, leaving time for re-leasing or repurposing which could create value if bought at distressed prices. Also, AT&T could monetize Whitacre Tower producing a one-time cash inflow; mispricings may appear in local CRE equity and single-asset REITs rather than broad VNQ/IYR, presenting selective alpha opportunities.

Key Decisions for Investors

• Establish a 2% long position in D.R. Horton (ticker: DHI) and a 1.5% long in Lennar (ticker: LEN) over 4–12 weeks to capture increased suburban residential demand from Plano relocations; trim positions if Dallas metro home-price appreciation outperforms by >5% q/q.
• Initiate a 1–1.5% short exposure to downtown office risk via buying 3–6 month IYR (iShares U.S. Real Estate ETF) 5% OTM puts sized to risk 0.5% portfolio, and/or selective short positions in Dallas-heavy office REITs if uncovered—reassess at 6 months or if CoStar vacancy moves >150 bps.
• For AT&T (ticker: T), deploy a defined-risk bullish options structure: buy Jan 19 2029 ~25-delta LEAP call and fund with sale of a same-expiry ~10-delta put (net risk ~1% of portfolio) to capture potential operational upside from consolidation while limiting downside from capex overruns; reassess after next 2 quarterly earnings/capex guidance releases.
• Implement a pair trade: long DHI (1.5%) / short IYR (1.5%) to express relative outperformance of suburban residential vs. downtown office over the next 12–24 months; close if the spread narrows by >50% or if Dallas CBD vacancy falls below pre-move baseline by >100 bps.
