Summary
Twilio closed fiscal 2021 with fourth-quarter revenue of $842.7 million, up 53.8% from the prior-year quarter. Full-year revenue reached $2.84 billion, up 61.3%. Gross profit in the quarter was $396.5 million, up 40.6%, and full-year gross profit was $1.39 billion, up 51.9%. Gross margin fell to 47.1% in the quarter, down 4.4 percentage points, and full-year gross margin was 48.9%, down 3.0 percentage points. The GAAP loss from operations was $283.6 million in the quarter, wider than the prior-year quarter. GAAP net loss was $291.4 million, also wider. For the full year, GAAP net loss widened to $949.9 million, and diluted GAAP net loss per share widened to $5.45. The gap between GAAP and non-GAAP results remained large. Non-GAAP loss from operations was $27.2 million in the quarter, compared with non-GAAP income from operations of $12.8 million a year earlier. Non-GAAP net loss per share was $0.20, versus non-GAAP net income per share of $0.04.
Operating metrics showed strong top-line momentum but some cooling in expansion. Dollar-Based Net Expansion Rate was 126% for the fourth quarter, down from 139% in the fourth quarter of 2020; excluding political traffic revenue in both periods, it was 130%. For the full year, Dollar-Based Net Expansion Rate was 131%, or 133% excluding political traffic. Active Customer Accounts totaled 256,000 as of December 31, 2021, up from 221,000 a year earlier. Acquisitions contributed meaningful revenue, with Twilio Segment and Zipwhip both adding to the top line. Organic revenue grew 34% year over year, or 39% when excluding political traffic revenue in both periods. Full-year organic revenue grew 42%, or 44% excluding political traffic. Twilio closed the Zipwhip acquisition in July 2021 for $838.8 million and the Segment acquisition in November 2020 for $3.0 billion. The company ended the year with 7,867 employees.
Guidance for the first quarter ending March 31, 2022 calls for year-over-year revenue growth of 45% to 47%, with organic year-over-year growth of 32% to 34%. The company expects a non-GAAP loss from operations and a non-GAAP loss per share of $0.26 to $0.22, based on 180 million non-GAAP basic shares outstanding. Management also repeated its goal of delivering non-GAAP operating profitability beginning in 2023. On the balance sheet, deferred revenue was $141.5 million at December 31, 2021, up 62.3% from the prior-year quarter, and remaining performance obligations were $154.2 million, up 83.4%. Full-year operating cash flow was negative $58.2 million, down from positive cash generation a year earlier. Capital expenditures were $46.0 million for the full year, up 78.4%.
The quarter came with a long list of risks. Twilio pointed to COVID-19, labor shortages, supply chain disruptions, inflation, rapid technological change, intense competition, and the challenge of integrating acquisitions. It also cited network service provider fees, A2P fees imposed by major U.S. carriers, changes in foreign exchange rates, and the impact of privacy changes on certain third-party platforms. A separate corporate event added uncertainty: on February 9, 2022, Syniverse and M-3 Brigade Acquisition II Corp. terminated their proposed merger because shareholder redemptions would have exceeded the minimum cash condition. Twilio will not purchase shares of MBAC. The Framework Agreement with Syniverse remains in force, and the parties are pursuing an alternative transaction in which Twilio would make a minority investment of $500 million to $750 million in Syniverse and enter into a wholesale agreement. Twilio also launched Twilio Ventures, a $50 million fund, and added Eyal Manor as Chief Product Officer and Dana Wagner as Chief Legal Officer. The company was named to Fortune's 2021 list of 100 Best Companies to Work For.

Risks
COVID-19 and related labor shortages, supply chain disruptions and inflation may reduce customer spending, lower renewal rates and delay sales cycles. MD&A states the broader implications of COVID-19 on results remain uncertain and these adverse conditions may continue for an extended period.
Gross margin declined to 47.1% in FY2021 Q4 from 51.5% in FY2020 Q4, a 4.4 percentage point decrease, and fell to 48.9% YTD from 52.0%. MD&A attributes the pressure primarily to carrier A2P SMS fees, international messaging growth, higher network service provider fees and acquired intangible amortization.
Net loss widened to $949.9 million YTD FY2021 from $490.98 million YTD FY2020, and operating loss widened to $915.58 million YTD from $492.90 million. Accumulated deficit was $2.1 billion as of December 31, 2021, and non-GAAP income from operations was only $2.5 million for FY2021.
Twilio completed large acquisitions including Zipwhip for $838.8 million in July 2021 and Segment for $3.0 billion in November 2020, and regularly pursues acquisitions, partnerships and investments. Integration may require significant management attention and may not achieve anticipated synergies or revenue benefits.
Dollar-Based Net Expansion Rate declined to 131% for FY2021 from 137% for FY2020. The business depends on existing customers increasing usage, but most customers lack long-term commitments and can reduce or cease use at any time.
International revenue was 34% of FY2021 revenue, up from 27% in FY2020, and international headcount grew from 1,369 to 2,964 employees between December 31, 2020 and December 31, 2021. International gross margin is typically lower than domestic, and expansion increases regulatory, compliance and currency risks.
Headcount grew from 4,629 employees on December 31, 2020 to 7,867 on December 31, 2021, straining culture and management. Twilio also faces competition for experienced enterprise sales professionals and new hires require significant training before full productivity.
As of December 31, 2021, Twilio had $1.0 billion of indebtedness outstanding, including 3.625% notes due 2029 and 3.875% notes due 2031. The indenture contains restrictive covenants and cross-default provisions that could accelerate debt if breached.
Privacy and cross-border data transfer rules, including GDPR, CCPA, CPRA, LGPD and the Schrems II ruling, create compliance costs and customer hesitancy. Twilio has experienced reluctance or refusal by European or multinational customers to use its services due to potential risk from Schrems II.
Telecommunications regulations apply in the U.S. and internationally, including FCC rules, robocalling standards such as SHAKEN/STIR, licensing and numbering resource requirements. An Australian Communications and Media Authority finding in 2019 against several companies, including Twilio, shows possible fines, audits or prohibitions.
The cloud communications market is intensely competitive and fragmented, with competitors that may bundle products at lower prices. Pricing pressures could reduce margins, especially as customers demand reductions when usage increases.
A February 26, 2021 critical feature enablement service overload caused connection issues across multiple products for a limited number of hours. Twilio increased server capacity and caching but cannot guarantee future disruptions will be prevented.
The Syniverse MBAC merger terminated on February 9, 2022 because redemptions would have exceeded the minimum cash condition; Twilio will not invest in MBAC and is pursuing a $500.0 million to $750.0 million minority investment in Syniverse with a wholesale agreement. The investment remains subject to closing conditions and market uncertainty.
