Bird: The Margin That Vanished When the Scooters Wore Out

What happened

Bird's ride profit looked like a business improving fast: 14.8% of sharing revenue in 2020 before vehicle depreciation, 44.4% in 2021, 54.6% in 2022 as deployed vehicles grew from 37,600 to 98,800. The measure that improved was quoted before the cost of the scooters wearing out. In November 2022 the company restated prior financials, having booked revenue on rides taken against preloaded wallet balances it had not yet earned. Bird Global and its subsidiaries filed for Chapter 11 in December 2023.

The case, start to finish

Every strategic call Bird made was steered by the margin with its largest cost of goods removed from it.

The fleet is the business

Buy scooters, leave them on public sidewalks, rent them by the minute through an app. There is no store, no counter and nobody at the point of sale. In an ordinary rental business the equipment is at least behind a door at night; here the asset lives outdoors, unattended, in the hands of strangers who have paid a few dollars and owe you nothing afterward.

That shape makes one accounting question load-bearing. Depreciation in a scooter fleet is not a schedule someone types into a spreadsheet. It is the physical world scoring the business. Bird depreciated its vehicles by usage against an estimated number of lifetime rides, and accelerated the charge on vehicles it determined were no longer active. That is the accounting name for a scooter that stopped reporting because it was broken, sunk, kept or simply gone. The filings even carry a line for the ones that were not there at all: vehicle count adjustments from physical inventory counts, $1.2 million in 2022 and $4.7 million in 2021.

Two margins, published side by side

Bird reported its unit economics twice, which is the tell. Ride profit before vehicle depreciation was 54.6% of Sharing revenue in 2022. Ride profit after vehicle depreciation was 28.8%. The 25.8-point gap between those two numbers was $59.8 million of scooters being consumed, about $1.29 of every ride.

Put that against what a ride actually brought in. In 2022 Bird recorded 46.5 million rides, $293.3 million of gross transaction value and about $231 million of Sharing revenue, which is roughly $4.97 a ride. But $31.0 million of that was unredeemed preloaded wallet balances, money riders had topped up and never spent. Strip it out and a real ride brought in about $4.31. So the scooter itself ate close to thirty cents of every dollar a rider actually paid to ride.

The company put the pre-depreciation figure forward as the headline measure of ride economics, describing it as the number that shows the cash return. That framing is defensible in isolation and disastrous as a steering wheel, because what is being used up here is not a support cost, it is the stock being sold. A rental margin quoted before depreciation is a restaurant quoting profit before food.

Scale aimed at the wrong constraint

Give Bird its due, because the operating record is better than the ending suggests. Ride economics improved three years running: before depreciation, 14.8% to 44.4% to 54.6% of Sharing revenue; after depreciation, negative 19.4% to 15.6% to 28.8%. Pushing charging and repair labor onto contractor Fleet Managers converted a payroll into a revenue share that only paid out when a scooter earned. Ruggedized hardware extended vehicle life, which is the only lever that genuinely moves depreciation per ride. By 2022 the fleet made money on a per-ride basis with the asset properly counted, and that is the hard part.

What went wrong was where the growth was pointed. Average deployed vehicles went 37,600 to 68,600 to 98,800. Average rides per deployed vehicle per day went 1.3, then 1.6, then back to 1.3. The newest scooter was ridden no harder than the first one, so each addition brought its own depreciation and an average day's demand. Scale moved the percentage and never closed the gap that mattered.

Sound unit economics are not a business

Here is the arithmetic that decided it. A 28.8% ride margin on about $231 million of Sharing revenue is $66.5 million of ride profit. General and administrative expense alone was $233.8 million, with $40.1 million of research and development and $16.3 million of selling and marketing above that. Total gross margin for the year was $34.7 million against a net loss of $358.7 million. Year-end cash was $33.5 million, with substantial doubt disclosed about the company continuing as a going concern. Bird filed Chapter 11 petitions on December 20, 2023.

Two things to take from it, and they pull in opposite directions on purpose. First, when you rent an asset, insist on seeing the margin after the asset is accounted for, and be suspicious of any headline number that has your largest cost of goods removed from it. Second, and less comfortable: Bird did the difficult thing and fixed its ride economics, and still could not carry the company sitting on top of them. Good unit economics are necessary. They are not, by themselves, a business.

Timeline

  • 2020 37,600 average deployed vehicles, 18.3 million rides. Ride profit before vehicle depreciation is $11.2 million, or 14.8% of Sharing revenue. After the scooters' depreciation it is negative $14.6 million. The fleet is losing money by being used.
  • 2021 68,600 average deployed vehicles, 40.2 million rides, and the sharpest year of operational improvement: ride profit before vehicle depreciation reaches 44.4% of Sharing revenue, and 15.6% after. Net loss for the year: $214.9 million.
  • November 2022 Bird files an amended 10-K restating prior financials. Its systems had booked revenue on rides completed against preloaded wallet balances that were uncollectible: money recorded as earned that riders did not have.
  • 2022 98,800 average deployed vehicles, 46.5 million rides, $293.3 million of gross transaction value. Ride profit before vehicle depreciation hits 54.6% of Sharing revenue; after depreciation, 28.8%. Net loss $358.7 million. Year-end cash: $33.5 million, with substantial doubt disclosed about the company continuing as a going concern.
  • December 20, 2023 Bird Global and subsidiaries including Bird Rides, Inc. and Skinny Labs, Inc. (dba Spin) file voluntary Chapter 11 petitions.

You're in the owner's chair

You run a shared-scooter fleet of 98,800 deployed vehicles. Your board's headline metric is ride profit before vehicle depreciation, currently 54.6% of revenue. Accounting keeps pointing out that the same rides are 28.8% once the scooters are counted. What do you do?

  • Steer on ride profit after vehicle depreciation, not before it
  • Grow the deployed fleet — the margin improves with scale, so scale it
  • Source cheaper scooters — attack the depreciation line at its price tag

The same rides, before and after the scooters wear out

  • 2021 ride profit — before vehicle depreciation: 44.4 % of Sharing revenue
  • 2021 — after vehicle depreciation: 15.6 % of Sharing revenue
  • 2022 — before vehicle depreciation: 54.6 % of Sharing revenue
  • 2022 — after vehicle depreciation: 28.8 % of Sharing revenue

From Bird's own reconciliation in its 2022 Form 10-K. The gap is vehicle depreciation: $49.8 million in 2021 and $59.8 million in 2022. Both pairs improved, and the pair that mattered was always the lower one.

Business model

Buy scooters, leave them on public sidewalks, rent them by the minute through an app. There is no store, no counter and nobody at the point of sale. The fleet is not a support cost for the business. The fleet is the business, and it lives outdoors, unattended, in the hands of strangers who have paid a few dollars and owe you nothing.

Revenue model

Per-ride charges: an unlock fee plus a per-minute rate, with a contractor "Fleet Manager" network taking a revenue share for charging and repair. In 2022 that produced 46.5 million rides, $293.3 million of gross transaction value and about $231 million of Sharing revenue, roughly $4.97 of revenue per ride. But $31.0 million of that was unredeemed preloaded wallet balances, cash riders topped up and never spent. Strip it out and an actual ride brought in about $4.31.

Cost structure

Bird published its unit economics twice, which is the tell. "Ride Profit (before Vehicle Depreciation)" was 54.6% of Sharing revenue in 2022; "Ride Profit (after Vehicle Depreciation)" was 28.8%. The 25.8-point gap between them was $59.8 million of scooters being used up, about $1.29 of every ride, or close to 30 cents of every dollar a rider actually paid to ride. Above that sat the company: $233.8 million of general and administrative expense, $40.1 million of research and development and $16.3 million of selling and marketing in the same year.

Strategic challenge

Depreciation in a scooter fleet is not a schedule on a spreadsheet. It is the physical world scoring the business. Bird depreciated its vehicles by usage, against an estimated number of lifetime rides, and accelerated the charge on vehicles it determined were "no longer active": the accounting name for a scooter that stopped reporting because it was broken, sunk, kept or gone. The filings even carry a line for the ones that simply were not there: "vehicle count adjustments" from physical inventory counts, $1.2 million in 2022 and $4.7 million in 2021, excluded from the ride-profit metric the market watched.

Key decision

Which margin to manage on. Bird put the pre-depreciation figure forward as the headline measure of ride economics, describing it as the number that shows the cash return. That framing is defensible in isolation and disastrous as a steering wheel, because in a rental business the asset being consumed is not overhead. It is the inventory. Every strategic call that followed, above all how fast to grow the deployed fleet, was made against a number that had the largest cost of the product removed from it.

What worked

More than the ending suggests. The ride economics genuinely improved three years running: before depreciation, 14.8% to 44.4% to 54.6% of Sharing revenue; after depreciation, negative 19.4% to 15.6% to 28.8%. Pushing charging and repair labor onto contractor Fleet Managers converted a payroll into a revenue share that only paid out when a scooter earned. Purpose-built, ruggedized hardware extended vehicle life, which is the only lever that actually moves depreciation per ride. By 2022 Bird had built a fleet that made money on a per-ride basis after the asset was accounted for. That is the hard part, and it did it.

What failed

Scale was pointed at the wrong constraint. Average deployed vehicles went 37,600 to 68,600 to 98,800, but average rides per deployed vehicle per day went 1.3, then 1.6, then back to 1.3. The newest scooter was ridden no harder than the first one, so each addition brought its own depreciation and an average day's demand. And even the fixed version of the fleet was too small for the company on top of it: 28.8% of about $231 million is $66.5 million of ride profit, against $233.8 million of general and administrative cost alone. Total gross margin for 2022 was $34.7 million against a $358.7 million net loss.

Risk factors

Assets left unattended outdoors and used without supervision; a depreciation life that is management's estimate of lifetime rides, so the reported margin moves when the estimate does; city permits that can be withdrawn; weather seasonality; a headline metric that excluded the biggest cost of goods; a restatement and a material weakness in the controls over revenue; and $33.5 million of cash against a loss running at more than ten times that a year.

Lesson summary

In a rental business the asset is inventory sold in slices, and a margin quoted before depreciation is a restaurant quoting profit before food. Bird's own filings show the scooter consumed about $1.29 of a $4.31 ride. The company then did the difficult thing and fixed it, and still filed Chapter 11, because a 28.8% ride margin on $231 million of rides was never going to carry $234 million of general and administrative cost. Sound unit economics are necessary. They are not, on their own, a business.
