• SiSonic MEMS microphones (digital and analog)

  MEMS microphones are tiny microphones built on a chip. They come in digital, analog and automotive versions, and over 25 billion sensor units have shipped to date, per the S-1/A.

• V2S vibration sensors

  Sensors that pick up vibration, sold alongside the microphones in the sensor product line.

• Neural Decision Processors and AISonic audio processors

  Low-power chips that run AI tasks on the device, for audio, sensor and vision uses (NDP100 to NDP250). A planned NDP3 chip is listed too. AI technology was in tens of millions of devices at Jun 30, 2026.

• AI software

  AI models, a Modeling Platform and a software kit for developers. Software and services brought $3.8 million in FY2025.

• Largest customer (not named)

  31%

  of revenue

  Provided 31% of revenue in the six months to Jun 30, 2026 and 38% in FY2025. The S-1/A calls it a technology and commercial partner. Price concessions on microphones led to reduced margins, and some negative-margin sales.

• Second-largest customer (not named)

  11%

  of revenue

  Provided 11% of revenue in the six months to Jun 30, 2026 and 15% in FY2025.

• All other customers

  58%

  of revenue

  58% of revenue in the six months to Jun 30, 2026 (Cityfort calculation from S-1/A filed Aug 31, 2026). The S-1/A says it has over 100 customers and names Samsung, Bose, Sonos, Nintendo, Roku, LG, Panasonic, vivo and others, without saying which are the two largest.

1. 1Customers paid $271.8 million in FY2025, of which $268.0 million was for products.
2. 2Total cost of revenue was $218.3 million, which left $53.5 million of gross profit.
3. 3Research took $52.5 million and sales and overhead $39.4 million. A $5.9 million write-down of unused equipment left an operating loss of $44.3 million.
4. 4Interest and other non-operating costs took $10.8 million ($4.0 per $100 of revenue), and income tax $5.8 million.
5. 5Costs were $60.9 million more than revenue: that is the net loss. Undeclared preferred dividends of $11.2 million make the loss for common stockholders $72.1 million.

Each line = amount ÷ total money in × 100. Lines may not add to exactly $100 because of rounding.

• Two sensor plants

  Sensors are assembled and tested in Suzhou, China (about 211,000 sq ft, sublet from Knowles to Mar 31, 2030). The other plant is in Penang, Malaysia (about 220,000 sq ft, leased in January 2026, initial term to Jul 18, 2028). Annual capacity is about 1.6 billion units.

• Outside chip factories

  Syntiant owns no chip factory. Its AI chips rely on two outside foundries, in Singapore and Taiwan. For wafer making overall, the S-1/A names foundries including Sony, TSMC, GlobalFoundries, SK keyfoundry and UMC. Its outside assembly and test partners include UTAC and ATX.

• Silicon wafers

  MEMS wafers come from a supplier in Japan. Syntiant has a remaining wafer and engineering-services purchase commitment of $33.6 million through Mar 31, 2027, taken on in the Knowles deal.

• People

  1,490 employees: about 1,200 in manufacturing in China and Malaysia, and about 190 in research and development.

• Patents

  Syntiant owns about 27 US and 26 foreign issued patents. It has a perpetual license from Knowles to about 200 US and 133 foreign issued patents, except for hearing-health uses.

• Qualcomm, NXP, STMicroelectronics, Synaptics, Texas Instruments

  Named in the S-1/A as competitors for AI processors.

• Infineon

  Named in the S-1/A as a competitor in both AI processors and sensing.

• AAC Technologies, Goertek, TDK

  Named in the S-1/A as competitors in sensing.

• Customers' in-house teams

  The S-1/A says customers' own in-house solutions compete with its software.

• Digital microphones

  Working

  Revenue up 6.0% to $89.9 million, six months to Jun 30, 2026

  Unit volumes rose, while the average selling price fell slightly, per the S-1/A.

  Status: Working, on track against what the company said.

• AI chips and software

  Early

  Revenue down 4.4% to $6.7 million, six months to Jun 30, 2026

  The S-1/A calls AI an emerging growth area. Lower one-off engineering services were partly offset by chip sales.

  Status: Early, too early to judge.

• Selling AI to sensor customers

  Early

  First AI smart glasses design win in 2025 (S-1/A)

  Shipments typically start 12 to 24 months after a design win. The S-1/A lists this platform strategy as a risk that may not win acceptance.

  Status: Early, too early to judge.

• Recent acquisitions

  New

  Orosound (Apr 10, 2026) and AudioSourceRE assets (Apr 22, 2026)

  Goodwill was $5.0 million at Dec 31, 2025 and $13.4 million at Jun 30, 2026.

  Status: New, recently announced.

Status compares progress with what the company itself said it would do: Working = on track against what the company said; Mixed = partly on track; Behind = behind the company's own plan; New = recently announced; Early = too early to judge.

EBITDA here = operating income plus depreciation and amortization (from the cash flow statement). Fiscal years are the company's own (December 31). Net profit is the share belonging to the company's owners. Total net income differs from net profit to the company's owners: Net loss was $60.9 million; $11.2 million of cumulative undeclared dividends on preferred stock made it a $72.1 million loss for common stockholders. The $16.26 loss per share rests on about 4.4 million weighted shares, because preferred stock has not converted.

Syntiant says in its S-1/A that it is an emerging growth company, so the filing gives two audited years instead of three.

• Net debt of $21.0 million is a Cityfort calculation from S-1/A filed Aug 31, 2026: balance-sheet debt minus cash. It was $7.1 million at Dec 31, 2025.
• The $52.2 million is after an $8.1 million unamortized discount. It covers the term loan ($53.5 million, including a $3.5 million end-of-term payment), the Seller Note ($6.0 million) and other debt ($0.85 million).
• The term loan is $50.0 million from Structural Capital, taken in December 2024 at a fixed 13.0%, with an effective rate of 23.4% in the first half of 2026. It matures on Dec 31, 2028, is secured on substantially all assets, and has 24 equal monthly principal payments from January 2027.
• Loan covenants (conditions the loan sets) require at least $15.0 million of unrestricted cash and $50.0 million of liquidity. For FY2026 they require revenue of at least $260.0 million and Adjusted EBITDA, as the loan defines it, no worse than negative $16.0 million. From Dec 31, 2027 they require Adjusted EBITDA of $5.0 million over trailing 12 months.
• The $50.0 million liquidity test also counts receivables and part of inventory, so it is not comparable with the total liquidity of $31.2 million at Jun 30, 2026 ($45.9 million at Dec 31, 2025).
• February 2026 amendments waived 2025 noncompliance with certain financial and nonfinancial covenants.
• An August 2026 lender commitment gave an option, exercisable by Oct 31, 2026, to delay principal to January 2028 and revise covenants. It carries an extra $5.0 million end-of-term fee. EDGAR shows no later filing as of Nov 5, 2026 that says if it was used.
• The S-1/A says it believes its cash and cash receipts will be sufficient for at least the next 12 months, based on its plans at that date. Redeemable preferred stock and warrants of $280.5 million sit outside equity; the accumulated deficit was $225.2 million.

  Watch Gross margin by segment in the next filing.

• Debt

  Loan conditions tied to revenue and cash

  The S-1/A says a default could speed up repayment. 2025 noncompliance was waived in February 2026, and the term loan sets a FY2026 minimum revenue of $260.0 million.

  Watch Whether the next amendment says the Oct 31, 2026 loan option was used.

• Cash and liquidity

  Losses and less cash

  The accumulated deficit was $225.2 million at Jun 30, 2026, and the S-1/A says Syntiant may not reach profitability. Cash fell from $45.9 million to $31.2 million in six months.

  Watch Cash and operating cash flow in the next period.

  AI revenue is still small

  AI was 5.1% of revenue in the six months to Jun 30, 2026 (Cityfort calculation from S-1/A filed Aug 31, 2026). The S-1/A says the plan to sell sensors, chips and models together may not win acceptance.

  Watch AI revenue and new design wins.

• Competition

  Larger competitors

  The S-1/A says competitors have greater resources and customers may build in-house. It names Qualcomm, Infineon, NXP, TDK and Goertek among others.

  Watch Average selling prices and customer wins in later filings.

• Size and price not yet set

  The S-1/A leaves the price range, shares offered, money raised, dilution and share count after the offering blank.

• Voting power concentrated with the founders

  Class B shares carry 10 votes each, against 1 for the Class A shares being sold, and the founders and certain trusts hold them all. Voting percentages are blank. The board has staggered 3-year terms.

• Part of the money goes to a holder

  The offering money repays the Seller Note owed to Knowles, a holder of more than 5%. The balance was $6.0 million at Jun 30, 2026. Knowles's CEO is a Syntiant director, expected to resign from the board before the registration statement takes effect.

• Broad discretion over the money

  Apart from the note, the money is for working capital, research and general purposes with no amounts given, and management has broad discretion, per the S-1/A.

• Results before and after the Knowles deal differ

  The S-1/A warns results before and after the December 2024 deal are not comparable. It says combined sensor revenue would have declined slightly in FY2025 had it owned the business from the start of 2024. It gives two audited years, as an emerging growth company may.

• Shares unlocked after 180 days

  The lock-up lasts 180 days after the prospectus date, and the lead underwriters may release shares at their discretion. Sales to cover tax on stock awards are an exception; share estimates are blank.

• No dividends

  Syntiant has never paid a dividend and says in the S-1/A that it does not anticipate paying one.
