  2. ELECTION OF DIRECTORS

    | THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT YOU VOTE “FOR” THE ELECTION OF CHE-WEI LIN AND ROBERT FLANAGAN AS CLASS I DIRECTORS. | |

  3. ELECTION OF DIRECTORS

    We have a classified Board consisting of two Class I directors, two Class II directors and three Class III directors. At each annual meeting of stockholders, directors are elected for a term of three years to succeed those directors whose terms expire at such annual meeting date. There are no arrangements or understandings between any director and any other person pursuant to which he or she is or was to be selected as a director of the Company. The term of the Class I directors, Che-Wei Lin and Dr. Elizabeth Loboa, will expire at the upcoming Annual Meeting. Accordingly, two persons are to be elected to serve as Class I directors of the Board at the Annual Meeting. The Board’s nominees for election by the stockholders to those two positions are current Class I member of the Board, Che-Wei Lin and new nominee, Robert Flanagan. After many years of dedicated service, Dr. Loboa will not stand for re-election and will be retiring from the Board at the conclusion of her current term. The Board thanks Dr. Loboa for her contributions and distinguished service. If elected, each nominee will serve for a term expiring at our annual meeting of stockholders in 2029 and hold office until their respective successors are duly elected and qualified. If any of the director nominees declines to serve or becomes unavailable for any reason (although we know of no reason to anticipate that this will occur), or if a vacancy occurs before the election, the proxies may be voted for such substitute nominees as we may designate. The proxies cannot vote for more than two persons. We believe that each of our directors has demonstrated business acumen, ethical integrity, and an ability to exercise sound judgment as well as a commitment of service to us and our Board.

  27. 2025 CEO Target Total Direct Compensation

    | Long Term Incentive | Short Term Incentive | | 50% of CEO and Other NEO Long-Term Incentive Compensation is Performance-Based: Rigorous, Pre-Set Three-Year Financial Goals. 50% of our CEO’s and other NEOs’ target long-term incentive annual equity grant was in the form of performance-based restricted stock units (“PSUs”). The PSUs are based 50% on a relative TSR goal and 50% on the attainment of a stock price hurdle, both measured over a three-year performance period. The threshold levels of performance that must be met before any PSUs are earned are rigorous and challenging. The compensation committee views the inclusion of a metric that includes relative TSR as critical because it ties executive officer compensation with the creation of stockholder value and aligns the interests of executive officers with those of the Company and its stockholders. By measuring our stock performance relative to peers, it mitigates the impact of macroeconomic factors, both positive and negative, that affect the industry and/or stock price performance and are beyond the control of management. Additionally, it provides rewards that are more directly aligned with performance through different economic cycles. The compensation committee believes this is particularly effective when coupled with an absolute TSR metric, which directly reflects the experience of the Company’s stockholders. The other 50% of our CEO’s long-term incentive equity grant was in the form of restricted stock units (“RSUs”), which drives longer-term retention, and provides some value even during periods of market or stock price underperformance. The proportion of total compensation that was variable and at-risk and the other performance-based metrics further enhanced the link between pay and performance for the CEO and NEOs in 2025 and strengthened the alignment of the | Short-Term Annual Cash Incentive: Rigorous, Pre-Set Annual Operational Goals. At the beginning of 2025, we established annual cash incentive plan targets for achieving certain operational milestones (“2025 Targets”) as outlined below. We believe the 2025 Targets were rigorous, aggressive, and challenging, attainable only by demonstrated commitment and strong performance by the management team. The 2025 Targets took into account the relevant opportunities and risks we were facing. Target 1 “Revenue” (25% Weighting). The 2025 Revenue target was $375,000,000, a 50% increase from 2024 actual revenue. In 2025, the Company’s revenue was $455.7 million, exceeding target under Target 1, earning the maximum payout for this Target 1 bonus. Target 2 “Non-GAAP Operating Income/Operating Loss” (25% Weighting). Non-GAAP Operating Income/Operating Loss is our GAAP operating income (loss) as defined under generally accepted accounting principles, excluding share-based compensation expense, expenses associated with discontinued products, non-cash expenses associated with discontinued products, amortization expense, and non-recurring expenses. The 2025 Non-GAAP Operating Income/ Operating Loss target was Non-GAAP Operating Income/ Operating Loss of $0, or breakeven. In 2025, the Company’s performance was between the minimum and reduced levels, earning a percentage of this Target 2 bonus. Target 3 “Design Win” (50% Weighting). The Company’s success and growth is dependent on the ability to sell new products and obtain significant market share from design wins. “Design Win” is defined as the successful completion of the evaluation stage, where our customer has tested our product, verified that our product meets substantially all of |

    | Long Term Incentive | Short Term Incentive | | interests of the executive officers with those of our stockholders. | their requirements and has informed us that they intend to purchase the product from us. The Design Win target was to complete two Design Wins in 2025. In 2025, the Company exceeded this target by obtaining three Design Wins under Target 3, earning the maximum payout for Target 3. |

  29. 2025 CEO Target Total Direct Compensation

    The compensation committee determined that the Company’s aggregate achievement under the three 2025 Targets for the short-term annual cash incentive plan was 104.79%. Additional details are provided below under the heading “2025 Annual Cash Bonuses.”

  30. Executive Compensation Policies and Practices

    | WHAT WE DO | | WHAT WE DON’T DO | | | | Maintain an Independent Compensation Committee. The compensation committee consists solely of independent directors. | | No Generous Perquisites. We provide only limited perquisites or personal benefits to our executive officers. | | | Retain an Independent Compensation Advisor. The compensation committee engages its own compensation advisor to provide information and analysis regarding our executive and equity incentive compensation programs. | | No Exclusive Executive Retirement Plans. We do not offer defined benefit pension arrangements and we do not provide retirement plans to our executive officers that are different from or in addition to those offered to our other employees. | | | Annual Executive Compensation Risk Assessment. The compensation committee annually reviews our compensation programs and compensation-related risks to ensure that our compensation programs do not encourage excessive or inappropriate risk-taking and that the level of risk that they do encourage is not reasonably likely to have a material adverse effect on us. | | No Special Health or Welfare Benefits. Our executive officers participate in broad-based Company-sponsored health and welfare benefits programs on the same basis as our other full-time, salaried employees. | | | | | No Hedging or Pledging of our Equity Securities. Our insider trading policy prohibits our executive officers, members of the Board and other employees from hedging or pledging our equity securities. | | | Meaningful Amount of Compensation At-Risk. Our executive compensation program is designed so that a significant portion of compensation is “at risk” based on our performance to align the interests of our executive officers and stockholders. | | No Dividends or Dividend Equivalents Payable on Unvested Equity Awards. We do not pay dividends or dividend equivalents on unvested RSUs and PSUs. | | | Succession Planning. We review the risks associated with our key executive officer positions to ensure adequate succession plans are in place. | | | | | Clawback Policy and Stock Ownership Guidelines. We have a clawback policy and stock ownership guidelines for our executive officers to align their interest with those of our stockholders. | | |

  31. Compensation-Setting Process

    | ● the financial and operational objectives established by the Board for the year at issue; | ● the annual performance review for each executive officer, including contributions to our overall performance, demonstrated leadership and significant individual achievements; | | ● the anticipated role that officer will play in the coming year in achieving those objectives and the cost and difficulty of replacing that individual; | ● our financial performance relative to our peers; | | ● internal pay equity among our executive officers; | ● the compensation practices of our compensation peer group and the positioning of each executive officer’s compensation as compared to our peer group; and | | ● each individual executive officer’s skills, experience, qualifications, and role relative to other similarly situated executives at the companies in our compensation peer group; | ● the recommendations provided by our CEO with respect to the compensation of our other executive officers. |

  32. Role of Compensation Consultant

    Role of Compensation Consultant The compensation committee retained Aon to assist with establishing an updated peer group for 2025 and to perform a pay study for executive officer and director compensation. Aon reported directly to the compensation committee and to the compensation committee chair. While Aon coordinated with our management for data collection, including for obtaining the job descriptions for our executive officers, Aon did not provide any other compensation related services to us. The compensation committee evaluated Aon’s independence pursuant to the listing standards of Nasdaq and the relevant SEC rules and determined Aon was independent and that no conflict of interest arose as a result of the work performed by Aon.

  34. Competitive Positioning

    Competitive Positioning For purposes of comparing the compensation of our NEOs against the competitive market, the compensation committee periodically reviews and considers the compensation levels and practices of a group of peer companies. This compensation peer group consists of companies within the industry with a similar size profile in terms of revenue and market capitalization. For 2025, the compensation committee assessed the appropriateness of the peer group to ensure it was aligned with the Company’s profile. Due to a significant increase in the Company’s valuation, as well as increases in revenues and headcount, the compensation committee approved changes to the peer group from the one used in connection with decisions about 2024 executive compensation. The following criteria were used to establish the 2025 peer group:

  35. Competitive Positioning

    | INDUSTRY | | | Focus on companies within the communications equipment industry and other similar technology hardware companies, including semiconductors and systems software companies; | | | MARKET CAPITALIZATION | Focus on companies with market capitalizations of $650 million to $4.0 billion based on the Company’s market capitalization of approximately $1.6 billion at the time; represented a range of approximately 0.4x to 2.5x the average of the Company’s 30-day average and spot market capitalization; | | REVENUE | Focus on companies with revenues of $280 million to $1.75 billion based on the Company’s 2024 actual and 2025 revenue projections; represented a range of approximately 0.4x to 2.5x 2025 revenue projections; and | | HEADCOUNT | Focus on companies with headcounts of 1,350 employees to 8,400 employees based on the Company’s year-end 2024 and projected 2025 headcounts; represented a range of approximately 0.4x to 2.5x the average of 2024 actual headcount and 2025 headcount projections. |

  36. Competitive Positioning

    | Accordingly, the compensation committee established the following compensation peer group for 2025 to assist with the determination of compensation for our executive officers (the “2025 Peer Group”): | | | A10 Networks, Inc. ACM Research, Inc. ADTRAN, Inc. Allegro MicroSystems, Inc Alpha and Omega Semiconductor Limited Calix, Inc. Cohu, Inc. Digi International Inc. Extreme Networks, Inc. FormFactor, Inc. | Harmonic Inc. Infinera Corporation MaxLinear, Inc. NETGEAR, Inc. NetScout Systems, Inc. Photronics, Inc. Ribbon Communications, Inc. Semtech Corporation SkyWater Technology, Inc. Viavi Solutions Inc. |

  37. Competitive Positioning

    | Using the criteria identified above, the compensation committee determined it was appropriate to make the following changes: | | | Companies Removed | Companies Added | | Aviat Networks, Inc. CEVA, Inc. Clearfield, Inc. Comtech Telecommunications Corp. indie Semiconductor, Inc. OneSpan, Inc. Vishay Precision Group, Inc. Xperi Inc | Allegro MicroSystems, Inc Calix, Inc. Extreme Networks, Inc. FormFactor, Inc. Infinera Corporation, MaxLinear, Inc. NetScout Systems, Inc. Viavi Solutions Inc. |

  39. 2025 Base Salary

    2025 Base Salary Base salary represents the fixed portion of the target direct compensation for our executive officers and serves to attract and retain highly talented individuals. The compensation committee determines adjustments to base salaries on an annual basis as well as in the event of a promotion or significant change in responsibilities. The compensation committee considers several factors in determining base salaries, including individual performance, the Company’s financial performance, competitive market data, experience, and tenure. The compensation committee generally references the 50th percentile when evaluating market competitiveness, but recognizes that individual factors, as noted above, may result in an individual being positioned above or below this market reference point. In 2025, referencing the competitive market as shown by the 2025 Peer Group, the compensation committee approved base salary increases of 16% to 22%, as well as to account for strong financial performance and stockholder value creation. The changes positioned three executives’ base salaries above the 50th percentile and two below the 50th percentile of the 2025 Peer Group, which the compensation committee viewed as appropriate based on performance.

  40. 2025 Annual Cash Bonuses

    2025 Annual Cash Bonuses We use annual cash incentive opportunities to attract and retain our executive officers consistent with market practice, to reward our executive officers for achievement of our corporate objectives, and to recognize outstanding contributions. 2025 Target Annual Cash Bonus Opportunities In establishing the target annual cash bonus opportunities for 2025, the compensation committee considered the competitive market information provided by Aon as well as the Company’s financial situation and opportunities, in order to allow the Company to provide an adequate incentive to retain our critical leadership and align pay with performance. In light of these considerations and given the substantial TSR and revenue performance, the compensation committee used target percentages to provide our NEOs with an appropriate level of reward for achievement of target performance of our critical corporate objectives described below and taking into account the Company’s much higher revenue and market capitalization. The compensation committee viewed the changes in target bonus opportunities as reasonable to align with the competitive market based on the 2025 Peer Group and noted that these amounts are earned only if the Company’s goals are achieved.

    The bonus opportunity is determined via linear interpolation with potential payouts ranging from 0-125% of target based on corporate performance. Minimum or below performance earns 0% of the target amount, Reduced performance earns 50% of the target amount, and Maximum performance earns 125% of the target amount for each executive. 2025 Corporate Performance Objectives The compensation committee believed that achieving the 2025 Targets should be the focus of the management team and their short-term cash incentive plan should be based on their performance relative to these targets. The compensation committee determined that no annual cash incentive would be earned with respect to a metric for performance below the minimum level set forth below. The compensation committee set the minimum, reduced, target, and maximum performance levels (as applicable) for the corporate performance measures as follows:

    2025 Actual Performance and Resulting Payments In January 2026, the compensation committee determined that for 2025 we met maximum performance for Target 1 described above, we were between minimum and reduced performance for Target 2 described above and met our maximum performance for Target 3 described above, resulting in payments at approximately 104.8% of the target awards. The dollar amounts for the target cash bonus opportunity as compared to the amounts earned are as follows:

  49. 2025 Long-Term Equity Incentive Compensation

    2025 Long-Term Equity Incentive Compensation We use equity incentive compensation to attract and retain our talent, to motivate them to achieve our corporate goals and to align their financial incentives with stockholder returns. Awards for 2025 Performance In 2025, the compensation committee granted awards of performance-based PSUs and time-based RSUs to the NEOs. 50% of the total award value was granted in the form of RSUs, which vest quarterly over a four-year period based on continued service. The remaining 50% of the total award value was granted in the form of PSUs, which are earned with respect to a variable number of shares (between 0% and 200% of the target number of shares) based on the Company’s achievement of preset performance goals. The PSUs granted in 2025 will vest 50% based on achievement of specified levels of relative TSR vs. the 2025 Peer Group (as summarized in the section above entitled “Competitive Positioning”), and 50% based on achievement of a specified stock price hurdle for a three-year performance period ending April 29, 2028. The stock price hurdle goal can be earned at any point during the performance period, but vesting is dependent on a recipient providing continuous service through the end of the performance period. The relative TSR payout and performance curve is summarized below. Payouts will be interpolated on a straight-line basis for performance in-between the percentiles noted below.

  52. 2025 Long-Term Equity Incentive Compensation

    In establishing the appropriate level of equity to our executive officers, the compensation committee considered the market information provided by Aon as well as the Company’s 2025 financial outlook, opportunities, and Company performance. The goal is to provide an adequate equity incentive to motivate our critical leadership while aligning management’s interests with stockholders’ interests and expectations. In light of these considerations, the compensation committee made meaningful increases in equity awards to our NEOs in 2025 as compared to 2024. In February 2025, the compensation committee approved the amounts for awards of RSUs to be granted to the NEOs pursuant to this approach as follows:

  53. 2025 Long-Term Equity Incentive Compensation

    | Named Executive Officer | Time-Vesting Restricted Stock Units* | Target Amount Performance-Vesting Restricted Stock Units* | Total Value at Target Performance | | Chih-Hsiang (Thompson) Lin | $2,850,000 | $2,850,000 | $5,700,000 | | Stefan J.

Kuo | $600,000 | $600,000 | $1,200,000 |

  54. 2025 Long-Term Equity Incentive Compensation

    * Value was converted to number of units on the applicable grant date based on the average closing price for the prior 20 trading-days. The compensation committee granted these RSUs to the NEOs under the 2021 Amended and Restated Equity Incentive Plan (the “2021 Plan”). The number of shares and grant date fair values for these awards are disclosed in the “2025 Summary Compensation Table” and “2025 Grants of Plan-Based Awards” table below. Earned 2022-2025 Performance-Based Restricted Stock Units In 2022, the compensation committee granted performance-vesting restricted stock units granted that vested 50% based on achievement of specified levels of relative total stockholder return, or relative TSR, and 50% based on achievement of specified

    stock price hurdle, for a three-year performance period ending April 29, 2025. The Company’s relative TSR for the period ended April 29, 2025 was at the 100th percentile, and the stock price for these purposes was $37.00, the combination of which translated to the maximum number of PSUs earned of 200% of target, as follows:

  58. Employment Agreements & Post-Employment Compensation

    Employment Agreements & Post-Employment Compensation We have entered into written employment agreements providing for at will employment with our CEO and each of our other NEOs. These employment agreements provided for their initial base salary and target bonus opportunity, as well as severance eligibility in the event of qualifying terminations of employment, including a termination of employment following a change of control of the Company (a so-called “double-trigger” arrangement). In the case of the acceleration of vesting of outstanding equity awards, we use this double-trigger arrangement to protect against the loss of retention value following a change of control of the Company and to avoid windfalls, both of which could occur if vesting of either equity or cash-based awards accelerated automatically or if cash severance amounts became due solely as a result of the transaction. We believe that having in place reasonable severance benefits, particularly for terminations in connection with a change of control, allow us to attract and retain highly qualified executive officers, permit those officers to focus on the best interests of the Company without undue concern for their own financial position in a change of control, and reduce conflict at the time of a termination through a pre-negotiated package conditioned on signing a release of claims. For detailed descriptions of the post-employment compensation arrangements we maintained with our NEOs for 2025, as well as an estimate of the potential payments and benefits payable under these arrangements, see “Potential Payments Upon Termination and Change of Control” below.

  59. Equity Grant Practices

    Equity Grant Practices We do not grant equity awards in anticipation of the release of material non-public information and we do not time the release of material non-public information based on equity award grant dates or for the purpose of affecting the value of executive compensation. In addition, we do not take material non-public information into account when determining the timing and terms of such awards. Although we do not have a formal policy with respect to the timing of our equity award grants, the compensation committee has historically granted such awards on a predetermined annual schedule. We currently do not grant any stock options to our employees, including our NEOs.

  62. 2025 Summary Compensation Table

    (1) Amounts for 2025 consist of the aggregate grant date fair value of the time-based RSUs plus the PSUs assuming target performance, both as granted by the compensation committee in April 2025 (aggregate grant fair value assuming maximum performance: Dr. Lin — $4,518,124; Dr. Murry — $1,823,096; Dr. Chang — $1,426,764; Mr. Yeh — $1,426,764; and Mr. Kuo — $951,176). The amounts included for RSUs granted in 2025 represent the aggregate grant date fair value computed in accordance with FASB ASC Topic 718, disregarding the estimate of time-based forfeitures. The assumptions used in calculating the grant date fair value of the RSUs are reported in Note B to the consolidated financial statements included in the Annual Report on Form 10-K for the year ended December 31, 2025 (the “Annual Report”). The amounts reported in this column do not correspond to the actual economic value that may be received by the NEOs for the RSUs.

In addition, the cost of personal use of a Company provided car for 2025 is included for Dr. Lin, with the amount determined based on the cost of the lease of the corporate car related to the proportion of mileage the car was driven for non-business trips, which was $34,794, and housing in Taiwan for 2025 while on business, which was $37,485. We also provided Mr. Yeh with a housing allowance for an apartment in Ningbo, China, given his responsibilities for managing operations in both China and Taiwan. The amount disclosed for Dr. Murry also includes $30,000 donated to a charitable organization for which Dr. Murry serves on the board of directors, consisting of $20,000 matching donation by the Company and $10,000 donated by Dr. Lin, excluding Dr. Murry. The amounts shown for Mr. Yeh for 2025 have been converted from NTD (New Taiwan dollars) and RMB (Chinese Yuan Renminbi), as applicable, to USD (United States dollars), using the exchange rate as of the last trading day of each applicable fiscal year, which on December 31, 2025, was 31.35 NTD = $1 USD and 6.99 RMB = $1 USD, respectively.

    Cash retainers paid to non-employee directors were paid on a quarterly basis and pro-rated for time served, as appropriate. In addition, the number of equity awards granted to our non-employee directors for 2025 under the 2021 Plan was calculated by dividing $190,000 by the closing price of our common stock on the date of grant. All RSUs granted to our non-employee directors vest in equal monthly amounts over the first twelve months following the date of grant, subject to early termination in accordance with their terms. The grant of RSUs was made following the election of directors at the 2025 Annual Meeting with a grant date of June 13, 2025. Directors were also reimbursed for out-of-pocket expenses incurred in the course of their service on the Board or its committees.
