ARM Holdings RSU India guide: post-IPO equity, Fidelity, and what Indian engineers should do with ARM shares

ARM Holdings (ticker: ARM) went public on NASDAQ in September 2023 in one of the largest tech IPOs of the decade, raising approximately $4.87 billion and valuing the company at ~$54.5 billion at IPO pricing. The stock, buoyed by the AI compute narrative (virtually every AI chip — NVIDIA, Apple, Qualcomm, MediaTek — uses ARM architecture), rose sharply post-IPO and trade above $150 at various points in 2024–2025.

ARM's largest engineering presence outside the UK is in India — primarily in Bengaluru (Prestige Tech Park and Manyata Tech Park areas) and Pune, with teams working on CPU microarchitecture (Cortex-A, Cortex-M, Neoverse), physical IP (standard cells, memory compilers), tools and infrastructure, and software/ecosystem. Indian engineers at ARM have held equity in various forms throughout ARM's ownership history (SoftBank private, then public again).

ARM's grant types

Grant type	Details
RSU (Restricted Stock Unit)	Standard grant; 4-year quarterly vest (post-IPO grants)
Pre-IPO grants	Various forms; many converted to ARM shares at IPO
ESPP	ARM does not operate an ESPP for India employees
PSUs	Issued at Director and VP+ levels; performance-based

Most India-based engineers (Engineer through Principal Engineer) receive RSU grants. Post-IPO grants follow the standard 4-year quarterly vesting schedule.

Pre-IPO grant holders: If you received equity grants while ARM was privately held (under SoftBank ownership, 2016–2023), those were likely in the form of ARM Limited shares or notional units that converted to ARM Holdings plc shares at the IPO. The cost basis and grant date for Indian tax purposes should reflect the original grant or vest date, not the IPO date — confirm with ARM India HR and your CA.

ARM RSU vesting schedule — 4-year quarterly

Post-IPO RSU grants at ARM typically follow the standard Silicon Valley 4-year quarterly schedule:

Year	% vested	Quarterly tranche
Year 1	25%	6.25% per quarter
Year 2	25%	6.25% per quarter
Year 3	25%	6.25% per quarter
Year 4	25%	6.25% per quarter

No cliff for standard grants. First vest approximately 3 months from grant date.

Vest dates for ARM India employees typically fall in February, May, August, November or January, April, July, October depending on grant date.

Post-IPO lockup: Employees who held ARM equity at the time of the September 2023 IPO were subject to a 180-day lockup (expiring approximately March 2024) during which they could not sell. For Indian tax purposes, the lockup restriction does not affect the cost basis computation — the perquisite is still recognised at the vest date FMV, not the sale date.

ARM's stock appreciation context

Period	ARM price (approx)	Key driver
IPO (Sep 2023)	$51	Listed at $51; valued at ~$54B
Q1 2024	$70–$80	Post-lockup; AI narrative strengthening
Q1 2024 peak	$164	AI compute hype; 10x PE premium to Qualcomm
Late 2024–2025	$100–$160	Normalisation; still elevated vs peers

ARM's post-IPO price trajectory has been driven primarily by the AI compute narrative — the argument that AI inference at the edge will run on ARM-based chips, expanding ARM's royalty addressable market beyond smartphones. Whether this thesis plays out determines where ARM's stock goes from current levels.

For Indian engineers who received pre-IPO grants, the appreciation from private-company grant price to post-IPO market price has been substantial — some multi-hundred percent gains. The tax implications depend on when shares vested (before or after IPO), the FMV used at each vest date, and the structure of the pre-IPO equity.

Fidelity NetBenefits — ARM's platform

Key sections:

Section	What to look for
Stock Plan → Holdings	ARM shares by lot: one lot per quarterly vest event
Stock Plan → Activity	RSU Release events; quarterly pattern
Tax Forms	1042-S for dividend withholding; 1099-B for sales
Statements	Annual statement; Jan 1–Dec 31 for Schedule FA

Account number: Under Account Settings in Fidelity NetBenefits. Required for Schedule FA.

ARM pays a dividend. Post-IPO, ARM has initiated a modest dividend programme. As an Indian resident (NRA for US purposes), ARM withholds 30% on dividends at source. You claim this as a foreign tax credit via Form 67 in ITR-2. The Form 1042-S in Fidelity's Tax Center shows the dividend amount and withholding.

Worked example: Principal Engineer, Bengaluru (post-IPO grant)

Assume a Principal Engineer who received a new-hire post-IPO RSU grant of $200,000 at ARM's IPO price of $51/share in October 2023:

• Grant: $200,000 / $51 = ~3,922 shares (4-year quarterly; 245 shares per quarter)
• First vest (January 2024): ARM at ~$65/share
• Quarterly perquisite: 245 × $65 = $15,925 × ₹84 TTBR = ₹13.4 lakh

But also: If you had a refresh grant at ARM's $140 price in 2024:

• Year 2 quarterly: original grant (245 shares at ~$100) + refresh grant vesting
• Income stacks significantly in Year 2 onward

Key nuance — post-IPO stock volatility: ARM's stock moved from $51 (IPO) to $164 (peak 2024) to ~$120 (normalised). The perquisite value at each quarterly vest depends on the stock price on that specific vest date — not the grant price. A vest at $164 generates 3x the INR perquisite of a vest at $51 for the same number of shares.

Pre-IPO grant holders: special considerations

If you received ARM equity while the company was private (notional units, phantom equity, or ARM Limited shares under SoftBank ownership), several questions need CA guidance:

1. What was the cost basis? If units were granted at a nominal price, the perquisite at vesting/IPO is the full FMV minus that nominal price.
2. What was the vest date FMV? For private-company shares, FMV may have been determined by a 409A valuation (a US fair value assessment). Your employer should have used this in Form 12BA.
3. Did the conversion to ARM Holdings plc shares at IPO trigger a taxable event? This is a CA question — in some structures, the conversion itself is a disposal and reacquisition at IPO price.
4. Lockup and the taxable event: If shares were vested pre-IPO but locked up, the vest date (not the lockup expiry) is typically the perquisite recognition date.

Get the specifics from ARM India HR and your CA before filing.

Form 16 reconciliation

ARM India (ARM Embedded Technologies Pvt Ltd / ARM India Private Limited) deducts TDS on RSU perquisites through India payroll:

Item	Form 16 location
RSU perquisite (quarterly vests)	Part B, Section B(1)(b)
PSU perquisite (if settled in the year)	Same section
TDS on perquisites	Part A; matches Form 26AS
Form 12BA	Lists each vest: share count, FMV, INR value

Verify the FMV used in Form 12BA against the actual ARM share price on each vest date in Fidelity. For quarterly vests, this is 4 data points per year to check.

Schedule FA for ARM shareholders

For each calendar year (Jan 1–Dec 31) when you held ARM shares:

Field	Value
Country	2 (United States of America)
Name of Entity	ARM Holdings plc
Address of Entity	110 Fulbourn Road, Cambridge CB1 9NJ, United Kingdom (registered address; US-listed)
Nature of Entity	Foreign Listed Company
Custodian	National Financial Services LLC (Fidelity's custodian entity)
Account Number	Your Fidelity NetBenefits account number
Peak Value (INR)	Highest ARM value × shares × TTBR during the calendar year
Closing Value (INR)	Dec 31 price × shares × Dec 31 TTBR

Note on ARM's domicile: ARM Holdings plc is incorporated in the United Kingdom (registered in England and Wales). It is listed on NASDAQ in the US. For Schedule FA purposes, the country is the US (where the shares are listed and the account is held), not the UK. Confirm with your CA.

Dividend disclosure

ARM pays a modest quarterly dividend. Same process as any US-listed dividend:

1. US withholding: 30% at source (reported on Form 1042-S)
2. Indian tax: gross dividend taxable at slab rate
3. Foreign tax credit: claim via Form 67 in ITR-2

Capital gains when you sell

Cost basis: FMV at vest date for each quarterly lot. For post-IPO grants, FMV is the market price on vest date (available from Fidelity transaction history).

STCG (< 24 months): Slab rate.

LTCG (≥ 24 months): 12.5% under Section 112.

Post-IPO volatility and LTCG planning: ARM's stock has been volatile post-IPO. If you received grants at $51 IPO price and lots vested at $65–$100, those lots become LTCG-eligible 24 months from each vest date. Lots vested in Q1 2024 become LTCG-eligible in Q1 2026. Monitor vest dates and calendar LTCG windows.

RSU concentration in a post-IPO semiconductor company

Post-IPO companies carry specific risks that mature public companies don't:

• Lock-up expiry selling pressure (mostly resolved for ARM by 2025)
• Valuation premium compression — ARM's AI narrative commanded 150–200x earnings; if the narrative weakens, multiple compression can cause large drops even without fundamental deterioration
• SoftBank overhang — SoftBank retained a majority stake post-IPO; large secondary sales are possible

The rational approach for ARM India engineers: sell each quarterly vest and redeploy into diversified index ETFs rather than compounding single-stock risk in a post-IPO company with a premium valuation.

Rovia makes this systematic. Transfer ARM shares from Fidelity to Rovia via ACATS (in-kind, no capital gains event), sell at 0.15% brokerage, redeploy into VTI or CSPX within the same account.

Compensation by level

ARM India (Bengaluru and Pune) works across CPU microarchitecture (Cortex-A78C, Cortex-X1, Neoverse V2), physical IP, tools and infrastructure, and software ecosystem. ARM competes for semiconductor talent with Qualcomm, Intel India, NVIDIA, and design services companies (Wipro, HCL Tech) for IC design talent.

Level	Title	Experience	New-hire RSU grant	RSU as % of TC
Engineer	Software/Hardware Engineer	0–3 years	$20,000–$40,000	12–18%
Senior Engineer	Senior Engineer	3–6 years	$40,000–$90,000	20–28%
Staff Engineer	Staff/Principal Engineer	6–10 years	$90,000–$180,000	28–38%
Principal Engineer	Principal Engineer	10–14 years	$180,000–$350,000	36–46%
Director	Director of Engineering	12+ years	$350,000+	46–56%

US estate tax

ARM shares held in Fidelity (a US broker) are US-situs assets subject to US estate tax for NRAs above the $60,000 exemption. At $150/share, 1,000 ARM shares = $150,000 — estate tax exposure of approximately ($150,000 − $60,000) × 40% = $36,000.

When selling ARM lots and redeploying into ETFs, choose Ireland-domiciled UCITS ETFs (CSPX, VWRA) rather than US-domiciled ETFs (VOO, VTI) to avoid extending the US estate tax footprint.
