Key Takeaways

Automotive gross margins excluding regulatory credits improved sequentially from 15.4% to 17.9%, with total gross margin exceeding 20.1%, the highest in over two years.
Energy business revenue hit $12.8 billion, up 26.6% YoY, with record quarterly gross profit from strong MegaPack and Powerwall deployments globally.
Paid Full Self-Driving customers reached 1.1 million worldwide (70% outright purchases), now fully transitioned to a subscription model creating short-term margin headwinds.
Free cash flow was $1.4 billion; operating expenses rose $500 million sequentially.
CEO Elon Musk confirmed Model S/X production winding down next quarter, with Fremont line converting to Optimus robot factory at 1 million unit capacity.
Robotaxi fleet surpassed 500 vehicles in Bay Area and Austin with rapid expansion; CyberCab production starts in April.
Capital expenditures expected to exceed $20 billion next year for factories, fleet, and AI compute, plus unguided AI chips and semiconductor investments.
Ended year with larger backlog, record deliveries in smaller international markets, strong APAC/EMEA demand, and robust energy backlog despite potential margin pressures.

Tesla’s Q4 and full-year 2025 earnings call, held on January 28, 2026, painted a picture of a company in transition. Despite a 16% quarter-over-quarter drop in vehicle deliveries and the first-ever annual revenue decline, Tesla showcased resilient gross margins, record energy storage deployments, and audacious bets on autonomy, robotics, and AI. CEO Elon Musk didn’t mince words: the company is evolving from a “hardware-centric business to a physical AI company,” with a new mission centered on “amazing abundance” and “universal high income” through AI and robotics. ❶ ❷ As a long-time Tesla watcher and EV/AI enthusiast, I see this as a pivotal moment—Tesla is doubling down on high-margin software and robotics to offset maturing auto sales. Let’s break it down.

Financial Highlights: Beating Expectations Where It Counts

Tesla reported Q4 revenue of $24.901 billion, down 3% YoY but ahead of some analyst whispers amid softer demand. ❷ Full-year revenue came in at $94.827 billion, a 3% decline—the first in company history—driven by a 9% drop in total deliveries to 1.636 million vehicles. ❷

Yet, the real story was profitability:

GAAP Gross Profit Q4: $5.009 billion (up 20% YoY), with a standout 20.1% gross margin—the highest in over two years. ❷
Automotive Gross Margin (excl. regulatory credits): Improved sequentially from 15.4% to 17.9%, thanks to favorable regional mix despite lower volumes and tariff headwinds. ❶
GAAP Net Income Q4: $840 million (down 61% YoY, impacted by Bitcoin valuation drops and FX losses).
Free Cash Flow Q4: A healthy $1.42 billion, with FY FCF surging 74% YoY to $6.22 billion. ❷
Balance sheet: $44 billion in cash and investments, up $7.5 billion for the year. ❷

Operating expenses rose $500 million sequentially, fueled by stock-based comp and AI investments. ❶ Non-GAAP metrics were stronger, with Q4 net income at $1.761 billion.

Metric	Q4 2025	YoY Change	FY 2025	YoY Change
Total Revenue	$24.9B	-3%	$94.8B	-3%
Gross Margin	20.1%	+386 bps	18.0%	+16 bps
Auto Margin (ex-credits)	17.9%	Seq. +2.5 pts	N/A	N/A
Free Cash Flow	$1.42B	-30%	$6.22B	+74%

These numbers signal cost discipline and diversification paying off. ❷

Automotive Segment: Deliveries Down, But Margins Up

Vehicle deliveries totaled 418,227 in Q4 (-16% YoY), with Model 3/Y at 406,585 and “other models” (S/3/X/Cybertruck) at 11,642 (-51%). FY production hit 1.65 million vs. 1.636 million delivered, leaving inventory at a lean 15 days. ❷

The silver lining? A larger backlog than recent years, boosted by record sales in smaller international markets and surging APAC/EMEA demand. ❸ Automotive revenue: $17.693 billion Q4 (-11% YoY).

Insight: Tesla’s factory utilization and mix shifts (more high-margin regions) cushioned the blow. But with global EV demand softening and tariffs looming, expect pricing pressures. Advice: Watch Cybertruck ramp—it’s transitioning to full autonomy mode. ❸

Energy Business: The Unsung Hero Hits Records

This segment stole the show:

Q4 Revenue: $3.837 billion (+25% YoY).
FY Revenue: $12.771 billion (+27% YoY)—aligning closely with the “nearly $12.8B” buzz. ❷
Deployments: Record 14.2 GWh Q4 (+29% YoY), 46.7 GWh FY (+49% YoY), led by Megapack and Powerwall. ❷

Musk called demand “insane,” with Megapack 3 and Mega Block ramps ahead. Backlog is “strong and globally diversified,” but risks include cheap competition, policy shifts, and tariffs squeezing margins. ❶

My Take: Energy now contributes ~15-20% of revenue but higher margins. It’s Tesla’s stealth growth engine—scale this to offset auto volatility. Pro tip for investors: Energy storage could be Tesla’s “picks and shovels” for the renewable boom.

Autonomy and FSD: Subscriptions, Robotaxis, and Unsupervised Miles

FSD Active Subscriptions: 1.1 million globally (+38% YoY), 70% upfront buys historically. ❷
Full shift to monthly subscriptions (doubling in 2025), creating short-term auto margin drag but recurring revenue upside. ❶

Robotaxi fleet: Over 500 vehicles in Bay Area and Austin, doubling monthly. Unsupervised paid rides in Austin (no safety drivers), with expansions to Dallas, Phoenix, Miami, etc., in H1 2026. FSD v14 leverages billions of real-world miles. ❷

Opinion: Autonomy is Tesla’s moat. Owners could Airbnb their cars for fleet income—game-changer for ROI.

The Robotics Revolution: Optimus Factory and Model S/X Sunset

Biggest bombshell: Model S/X production winds down Q1 2026, with Fremont lines converting to Optimus factory (1 million units/year capacity). ❶ Musk: “Slightly sad… honorable discharge,” but necessary for autonomy shift. ❸

Optimus Gen 3 unveils Q1 2026 (production-ready), start before year-end. Musk: “Optimus will move the needle on US GDP significantly.” ❶ Tesla leads China in hands, AI, scaling.

Insight: Humanoids solve labor shortages. Tesla’s vertical integration (physics-first design) positions it for trillions in market. Risk: Slow ramp like EVs.

Cybercab: Production in April, Massive Scale Ahead

Cybercab volume production starts April 2026 (slow S-curve ramp), no wheel/pedals, optimized for 50-60 hours/week utilization. Long-term volume to eclipse other models; Semi and Megapack 3 also 2026. ❸

90% of miles are 1-2 passengers—perfect fit. Musk eyes 25-50% US robotaxi coverage by year-end.

2026 CapEx Explosion and Strategic Bets

CapEx >$20 billion for six factories (Cybercab, Semi, Optimus, energy), AI compute, fleet. Excludes chips/semiconductors (TerraFab planned domestically). ❶ Plus $2B xAI investment. ❸

Cash hoard funds it, with bank financing for fleets.

Risks, Challenges, and Forward Outlook

Headwinds: Tariffs, competition (esp. China robots/energy), FSD reg hurdles, supply chains (chips, batteries).
Tailwinds: Backlog growth, AI/software margins, global FSD rollout (Korea: 1M km/month). ❷

Musk: “The future is more exciting than you can imagine.” ❸

Investor Advice: Buy the Dip, Bet on AI

Tesla stock edged up post-earnings—smart money sees beyond deliveries. ❹ Bull case: Optimus/Cybercab unlock $10T markets; energy/FSD recur. Bear case: Execution delays, macro EV slump.
